The third claim of reissued letters patent No. 978, granted to
William S. Carr, June 12, 1880, for "improvements in water closets"
(the original patent having been granted to him August 5, 1856,
and, as reissued, extended July 23, 1870, for seven years from
August 5, 1870), namely,
"In a valve for water closets, a cup leather for controlling the
motion of said valve in closing gradually, substantially as
specified, said cup leather moving freely in one direction, and
closing against the containing cylinder in the other direction, and
the leakage of water in said cylinder allowing the movement
Page 114 U. S. 2
of said cup leather as set forth,"
construed, and the operation of the device explained.
The state of the art as to prior devices and the construction
and operation of the defendants' device, set forth.
In view of the state of the art,
held that for the
purpose of securing the free passage of water in one direction and
preventing its escape in the other direction otherwise than
gradually, the defendants had used nothing which they did not have
a right to use, and had not appropriated any patentable invention
which Carr had a right to cover, as against the defendants'
structure, by the third claim of his reissue.
All that Carr did, if anything, was to add his form of orifice
to the valve and cup leather of an existing pump plunger.
The third claim of the Carr reissue involves as an element in it
the means of leakage set forth.
The only point of invention, if it could be dignified by that
name, was the special means of leakage shown by Carr, but which the
defendants did not use.
To be patentable, a thing must not only be new and useful, but
must amount to an invention or discovery.
Recent decisions of this Court on the subject of what
constitutes a patentable invention cited and applied.
Under them, claim three of the Carr reissue must, in view of the
state of the art, either be held not to involve a patentable
invention or, if it does, not to have been infringed.
The first claim of letters patent No. 21,734, granted to
Frederick H. Bartholomew, October 12, 1858, for an "improved water
closet," and extended October 2, 1872, for seven years from October
12, 1871, namely, "The use of a drip box or leak chamber arranged
above the closet and below and around the supply cock substantially
as described," must, in view of the state of the art, be limited to
a drip box arranged above or on top of the closet, and is not
infringed by a structure in which the drip box is cast on the side
of the trunk, near the top but below it and not on top of it.
These are suits in equity to restrain infringements of a patent.
The facts which make the case are stated in the opinion of the
Court.
MR. JUSTICE BLATCHFORD delivered the opinion of the Court.
These are four suits in equity. The first one was brought
Page 114 U. S. 3
in February, 1877, in the Circuit Court of the United States for
the Eastern District of Missouri by Charles F. Blake, as trustee of
William S. Carr and Frederick H. Bartholomew, against Elizabeth E.
Boisselier and John C. Kupferle for the infringement of reissued
letters patent, No. 978, granted to William S. Carr, June 12, 1860,
for "improvements in water closets," the original patent having
been granted to him August 5, 1856, and, as reissued, extended,
July 23, 1870, for seven years from August 5, 1870.
The second suit was brought in February, 1879, in the same court
by Charles F. Blake, as trustee of Sarah Bartholomew, against the
same defendants for the infringement of letters patent, No. 21,734,
granted to Frederick H. Bartholomew, October 12, 1858, for an
"improved water closet," and extended, October 2, 1872, for seven
years from October 12, 1872.
The third and fourth suits were brought in July, 1879, in the
Circuit Court of the United States for the Southern District of New
York by Charles F. Blake, as trustee, etc., and William S. Carr and
Sarah M. Bartholomew -- one against the McNab & Harlan
Manufacturing Company and John Harlan and the other against John
Eaton and others, each for the infringement of the said Carr patent
as reissued and extended, and of the said Bartholomew patent, as
extended.
In each of the two suits in Missouri, a decree was made in May,
1880, adjudging that the patent sued on was not good and valid in
law and dismissing the bill. In each of the two suits in New York,
a decision was made in February, 1881, 7 F. 821, adjudging that the
two patents were good and valid in law and that the third claim of
the Carr reissue and the first claim of the Bartholomew patent had
been infringed and awarding an account of profits and damages, and
in January, 1882, a final decree was made in one suit for $1,200
damages and $118.74 costs, and in the other for $415 damages and
$101.24 costs. The plaintiffs in interest in each of the Missouri
suits and the defendants in each of the New York suits have
appealed to this Court. The questions are the same in all of the
suits, and arise on the same proofs.
The third claim of the Carr reissue is the only claim of
that
Page 114 U. S. 4
patent which is alleged to have been infringed. So much of the
specification of that reissue as relates to that claim is as
follows:
image:a
"Fig. 1 is an elevation of my closet as in place for use; Fig. 2
is a plan of the cock and part of the plan of said closet, and Fig.
3 is a vertical section of my cock made use of in letting the water
into and shutting the same off from said closet.
Page 114 U. S. 5
Similar marks of reference indicate the same parts in all the
figures. The nature of my said invention consists in a peculiar
construction of cock which is opened by the motion of the seat of
the water closet, and allows but little water to run into the pan
of the closet until the weight is removed from the seat, when the
cock, gradually closing of itself, allows the water to run for a
limited and regulated time sufficient to wash out the basin. . .
."
image:b
"In the drawing,
a is the trunk on the upper end of the
soil pipe
b, fitted with the pan
r on the shaft
or spindle
q, and
c is the basin setting on to
the trunk
a. These parts, thus far, are to be of any usual
or desired character;
d is a pipe supplying water from any
suitable head, and said pipe is attached to the coupling 1 that
screws on to the body
e of the cock, and
f is a
pipe and coupling passing water (when admitted as hereafter
detailed) to the basin
c, where it is to be fitted with
the deflector as usual. The cock
e that supplies water to
the basin is constructed with a stem
h, passing nearly or
quite air-tight through the leather washer 4 beneath the cap
n, and the lower end of said stem
h is formed
with a valve
g and with
Page 114 U. S. 6
a cylindrical part 3, fitting water-tight or nearly so, the
opening of the washer 2 between the coupling 1 of the pipe
d and cock
e and the sides of this cylinder 3 are
formed with notches or a groove
x. It will now be seen
that if the stem
h be pressed down by the weight of the
person acting on the seat
u, rod
v and lever
p, or by any other suitable means, the valve
g
will be forced away from the washer 2 and allow a dash of water to
pass through the notch
x sufficient to fill up the parts
of the cock, and then that the cylinder 3, descending and filling
the opening in the washer 2, will prevent, or nearly so, the
passage of any more water into the closet;
i is a spring
around the stem
h which acts in aid of the pressure of the
water on the valve
g to close the same as soon as the
force which opened the said valve is removed, but, if this alone
was used, the concussion would be so great as to tend to break the
parts, besides which sufficient water would not be supplied to the
water closet to cleanse the same. I therefore make use of the
following means, which cause said valve
g to close slowly
and in a regulated amount of time, thereby allowing the desired
quantity of water to dash past the washer 2 at the time the notches
or openings
x are moving past the same. The upper part of
the cock
e is formed as a cylinder
k, in which is
a disk
l, attached to the stem
h and a cup
leather
m above the same;
n is a cap of the
cylinder
k which is formed with a short tube 8, passing up
through a hollow projection 0, from the side of the trunk
a and secured thereto by a nut 6. At the time the valve
g is pressed down as before stated, the water dashes
momentarily on to the cock and fills the same, passing the cup
leather
m and filling the cylinder
k and, upon
the pressure on the stem
h being removed, the cup leather
expands by the slight rise of the stem, and would retain the valve
g open were the cylinder
k water-tight, and
therefore the closing of said valve will be regulated according to
the extent of leakage provided in said chamber
k, and for
this purpose the leakage at the washer 4 around the stem
h
may in some cases be sufficient; but I propose to use a screw 9,
entered through the cap
n with a head next the washer 4
and part of one side of the screw filed away, so as to adjust the
amount of leakage and regulate
Page 114 U. S. 7
the time during which the water will run into the closet. . . .
I am also aware that a given amount of water leakage has been used
to prevent a sudden motion in cocks, balances, meters, and a
variety of other instruments; therefore, I do not claim the same,
but I am not aware that a cup leather has ever before been so
fitted and applied with a valve as to allow the water to pass the
said cup leather freely in the chamber in which it moves and then
act, when the power is relieved from the valve, upon the water in
said chamber and gradually allow the valve to close."
The third claim of the Carr reissue is as follows:
"Third. I claim, in a valve for water closets, a cup leather for
controlling the motion of said valve in closing gradually,
substantially as specified, said cup leather moving freely in one
direction, and closing against the containing cylinder in the other
direction, and the leakage of water in said cylinder allowing the
movement of said cup leather as set forth."
In the Carr apparatus, the valve is combined with a containing
cylinder and a cup leather in such manner that the valve is caused
to close slowly because the action of the cup leather as a tight
packing prevents the passage of water while the valve is closing,
and the valve can open rapidly because, as it opens, the cup
leather does not act as a packing, but permits the passage of water
outside of it. In the containing cylinder there is a piston which
has on it centrally a cup leather, and is provided with a small
aperture which permits the gradual escape of water from it. When
the cylinder is filled with water, the valve is held to its seat by
a spiral spring. When the valve stem is depressed, the valve opens
rapidly because the cup leather permits the water to pass freely
outside of it. When the force which depressed the valve-stem is
removed, the spring acts to shut the valve, but it shuts slowly
because the cup leather acts as a tight packing, being forced
outward against the inner wall of the cylinder by the pressure of
the water. Therefore the water escapes slowly from the cylinder
through the small aperture, and the valve cannot move faster in
shutting than it is allowed to move by the escape of the water
through the small aperture.
Page 114 U. S. 8
The apparatus alleged to infringe the two patents is the same in
all of the suits. It has a brass casting, and is thus described by
the plaintiff's expert:
"This brass casting of the defendants has at its lower part a
cavity whose walls partially bound the variable chamber. This
cavity is a cup-shaped piece of brass screwed to the bottom of the
casting. A cylindrical brass plunger enters this cavity, and the
upper end of it is formed into a valve. This brass plunger is
packed to the top of the cavity by a cup leather, which is secured
between the upper part of the brass cup and an internal flange on
the brass casting. The stem of the plunger and valve is surrounded
by a coiled brass spring, which always tends to lift the plunger
and shut the valve. The plunger has also a small nick or groove cut
in its periphery and extending from the top to the bottom of the
plunger. When this contrivance is ready for operation, all parts of
the cavity in the brass casting, including the variable chamber,
are filled with water and the valve is held on its seat by the
spiral spring, the plunger then being in its highest position. When
it is desired to open the valve, force is applied to depress the
valve stem; this force compresses the spring, depresses the
plunger, and opens the valve quickly owing to the fact that the
water can escape rapidly from the variable chamber, such rapid
escape being due to the operation of the cup leather, which now
ceases to hug the plunger and acts as a valve, permitting the water
to escape freely from the variable chamber. When the force which
was applied to depress the stem and open the valve is removed, then
the spring strives to shut the valve and elevate the plunger, and
as soon as it commences to elevate the plunger, the pressure of
water causes the cup leather to hug the plunger tightly so that it
ceases to act as a valve and becomes a tight packing. As soon as
this occurs, water can only enter the chamber through the small
groove in the periphery of the plunger, and the valve can shut no
faster than this small flow of water permits it to shut."
It is shown by the evidence that cup leathers had been used in
the central valves of the plungers of pumps, the cup leather
contracting on the downstroke and allowing the water to
Page 114 U. S. 9
pass by and spreading out on the upstroke and raising the water,
and that it was not new to employ a variable chamber to effect, by
the gradual escape of water from it, the slow and gradual closing
of a valve.
In George Hulme's English patent No. 8,971, of November, 1841,
is shown a device for "keeping a valve a open for any required
length of time for the supply of water to the basins of water
closets generally." The specification says:
"To regulate the length of time that the valve, F, may be kept
open for the flow of water from the reservoir to the basin of the
closet after the pan or valve has closed, the barrel A A is
furnished with the openings N N communicating from the under to the
upper side of the bucket D and fitted with a cock O. Now by turning
the cock O in such a position that the waterway through the cock O
will be diminished, more time will be required for the bucket to
displace the contents of the barrel, and
vice versa."
The bucket D does not have a cup leather, but has a central
valve E to allow the water to pass.
The defendants have substantially the Hulme construction, using
a cup leather centrally, instead of the Hulme central valve. A
central valve being old, and a cup leather being old, and a central
valve and cup leather combined being old, and a plunger with a
central valve and a means of regulating the escape of the water
from above it being old, and the device for the escape of the
water, used by the defendants, being the same as in Hulme, it must
be held that for the purpose of securing the free passage of water
in one direction and preventing its escape in the other direction
otherwise than gradually, the defendants have used nothing which
they did not have a right to use, and have not appropriated any
patentable invention which Carr had a right to cover, as against
the defendant's structure, by the third claim of his reissue. If
Carr had made the defendants' form of structure when he made his
own, he would not, in view of the state of the art, have made
anything having patentable novelty in it, and therefore what he has
claimed in claim 3 of his reissue has no patentable feature which
the defendants' form of structure infringes. The action of the cup
leather in Carr's structure and in the defendants' to admit
Page 114 U. S. 10
the free passage of the water while the valve is moving in one
direction and to prevent such passage while the valve is moving in
the other direction is due to the flexibility of the leather and to
the pressure of the water on its different sides alternately, and
to its position with reference to the wall of the chamber, and is
the same as in the old central valve of a pump plunger, which was
furnished with a cup leather. The effect resulting from allowing
the water, which cannot return through the passage by which it
entered, to escape by a small orifice and gradually, and thus cause
a gradual movement in a valve attached to the central stem, is due
to the small orifice. All that Carr did, if anything, was to add
his form of orifice to the valve and cup leather of the pump
plunger. But the idea of having openings extending from one side to
the other of a bucket, and thus regulating the closing of a water
valve by the slow escape of the water from the upper side of the
bucket through such openings, was fully exhibited in the apparatus
of Hulme.
Claim 3 of Carr's reissue speaks of the cup leather as "moving
freely in one direction and closing against the containing cylinder
in the other direction." This action existed in the cup leather of
the old pump plunger. The claim also says, "the leakage of water in
said cylinder allowing the movement of said cup leather, as set
forth." This means that the greater or less extent of the leakage
allows a faster or slower movement of the cup leather and a faster
or slower closing of the valve. The claim involves, therefore, as
an element in it, the means of leakage set forth. It says that the
use of the cup leather is "for controlling the motion of said valve
in closing gradually, substantially as specified." But it is the
gradual escape of the water through the small orifice which
controls the motion of the valve. The cup leather does not control
such motion. The only action of the cup leather is the same which
it had in the old pump plunger: to hold up a column of water and
act as a packing to prevent the return passage of the water. In
this condition of things, it would seem that the only point of
invention, if it could be dignified by that name, was the special
means of leakage shown by Carr of having a screw through the cap
with part of the screw filed away, and
Page 114 U. S. 11
which is not used by the defendants, who use the same means of
leakage as Hulme did.
The provision of the Constitution, Article I, Section 8,
subdivision 8, is that Congress shall have power
"to promote the progress of science and useful arts, by securing
for limited times to authors and inventors the exclusive right to
their respective writings and discoveries."
The beneficiary must be an inventor, and he must have made a
discovery. The statute has always carried out this idea. Under the
Act of July 4, 1836, 5 Stat. 119, § 6, in force when these patents
were granted, the patentee was required to be a person who had
"discovered or invented" a "new and useful art machine,
manufacture, or composition of matter," or a "new and useful
improvement in any art, machine, manufacture, or composition of
matter." In the Act of July 8, 1870, 16 Stat. 201, § 24, the
patentee was required to be a person who had "invented or
discovered any new and useful art, machine, manufacture, or
composition of matter, or any new and useful improvement thereof,"
and that language is reproduced in § 4886 of the Revised Statutes.
So it is not enough that a thing shall be new in the sense that in
the shape or form in which it is produced, it shall not have been
before known, and that it shall be useful, but it must, under the
Constitution and the statute, amount to an invention or
discovery.
To refer only to some more recent cases, adjudged since these
suits were decided below, this principle was applied in
Vinton
v. Hamilton, 104 U. S. 485,
where, a cupola furnace being old, and a cinder notch being old,
and the use of a cinder notch to draw off cinders from a blast
furnace being old, and the cinder notch, in drawing off the cinder
from a cupola furnace, performing the same function as in the blast
furnace, it was held that the application of the cinder notch to
the cupola furnace would occur to any practical man, and that there
was nothing patentable in such application.
In
Hall v. Macneale, 107 U. S. 90, a
cored conical bolt in a safe with a screw thread on it, having
existed before, and also a solid conical bolt, it was held to be no
invention to add the screw thread to the solid conical bolt.
Page 114 U. S. 12
In
Atlantic Works v. Brady, 107 U.
S. 192,
107 U. S. 200,
it was said, that it is not the object of the patent laws to grant
a monopoly for every trifling device which would naturally and
spontaneously occur to any skilled mechanic or operator in the
ordinary progress of manufactures, and this doctrine was applied in
Slawson v. Grand Street Railroad Co., 107 U.
S. 649; in
King v. Gallun, 109 U. S.
99; in
Double-Pointed Tack Co. v. Two Rivers
Manufacturing Co., 109 U. S. 117; in
Estey v. Burdett, 109 U. S. 633; in
Bussey v. Excelsior Manufacturing Co., 110 U.
S. 131; in
Pennsylvania Railroad Co. v. Locomotive
Truck Co., 110 U. S. 490; in
Phillips v. City of Detroit, 111 U.
S. 604; in
Morris v. McMillin, 112 U.
S. 244, and in
Hollister v. Benedict Manufacturing
Co., 113 U. S. 59.
In the case last cited, the thing claimed was new in the sense
that it had not been anticipated by any previous invention and it
was shown to have superior utility, yet it was held not to be such
an improvement as was entitled to be regarded in the patent law as
an invention. The claim was
"A stamp the body of which is made of paper or other material,
and having a removable slip of metal or other material, displaying
thereon a serial number, or other specific identifying mark,
corresponding with a similar mark upon the stub, and so attached
that the removal of such slip must mutilate or destroy the
stamp."
The part designed to become a stub when the stamp proper was
separated therefrom, and displaying a serial number, was well
known, and so was the constituent part of the stamp proper designed
to be permanently attached to a barrel. The third element -- namely
a constituent part of the stamp proper displaying the same
identifying serial number as the stub, which part, after the stamp
proper had been affixed to the barrel, bore such relation to the
permanent part that it could be removed therefrom so as to retain
its own integrity but to mutilate and thereby cancel the stamp by
its removal, was not new so far as the contents of such constituent
part were identical with those on the stub. But the question turned
on that feature of the third element whereby a removable part of
the stamp proper, the contents of which identified the stamp with
the stub after the stamp had been attached, could be so removed
Page 114 U. S. 13
as to retain its own integrity but mutilate and thereby cancel
the stamp by its removal. This was held not to be a patentable
invention and
"not to spring from that intuitive faculty of the mind put forth
in the search for new results or new methods creating what had not
before existed or bringing to light what lay hidden from vision;'
but to be only 'the display of the expected skill of the
calling,"
and involving
"only the exercise of the ordinary faculties of reasoning upon
the materials supplied by a special knowledge and the faculty of
manipulation which results from its habitual and intelligent
practice,"
and to be "in no sense the creative work of that inventive
faculty which it is the purpose of the Constitution and patent laws
to encourage and reward."
On these principles, claim 3 of the Carr reissue must, in view
of the state of the art, either be held not to involve a patentable
invention or, if it does, not to have been infringed.
The specification of the Bartholomew patent says:
"The nature of my invention consists in providing for water
closets a cistern or drip or leak chamber arranged upon the top of
or over the trunk of a closet, and placing a supply cock within or
above said drip box or cistern so that any waste or leak or drip
from the cock shall be conducted into the trunk so as to insure the
keeping of the floor dry. . . . Fig. 1 is a prospective view of a
pan-closet, showing my drip box arranged upon the top plate of the
closet and the cock for supplying water to the same secured to the
closet within the drip box. . . . The general form of the closet is
such as is in common use. Upon the cover R I cast a box, enclosure,
or cistern E, about one inch high (more or less), and broad enough
to admit of placing the 'A' cock (I use a valve cock) within the
cistern, and (where it is practicable) so as also to receive the
drip that may escape from the joint at the arm of the basin, called
the 'putty-joint.' I screw the cock into the cover of the closet,
and make a hole within the drip box or in the bottom of the cock to
admit the leak to fall into the trunk P, and not onto the
floor."
The first claim of the patent, which is the only one alleged to
have been infringed, reads thus:
"First. I claim the use of a drip box or leak chamber arranged
above the closet
Page 114 U. S. 14
and below and around the supply cock, substantially as
described."
The defendants' structure has a trunk and a supply cock and a
drip box arranged below and around the supply cock, but the drip
box is cast on the side of the trunk, near the top but below it and
not on top of it. The drip goes into the drip box and thence into
the trunk and the soil pipe. The following devices are shown to
have been old: a drip cup or drip box; a pipe to convey away
drippings, in machinery, from a drip box arranged in connection
with a cock; a drip cup applied to the valve of a water closet, the
leakage from the valve falling into a saucer, and thence finding
its way, through a hole, into the inside of the trunk; a valve on
the floor at the foot of the trunk; a valve attached to the trunk
and below its top; a valve above its top; a valve with a drip pan
conducting the drip into the soil pipe at the foot of the trunk; a
valve on top of the trunk, and a provision, by means of a hollow
arm, to conduct the drip into the trunk. In view of this state of
the art, the claim must be limited, as defined by its language and
that of the specification, to a drip box "arranged upon the top of
or over the trunk" -- "arranged upon the top plate" -- cast "upon
the cover" -- "arranged above the closet." The limitation imposed
by the patentee must be presumed to have been made with good
reason, and even if there was anything patentable in the claim as
it reads, it cannot, in view of the state of the art, be extended
to cover any structure except one which has a drip box arranged
above or on top of the closet, and therefore has not been
infringed.
From these considerations it results that
The decrees in the Missouri suits must be affirmed, and
those in the New York suits must be reversed with directions to
dismiss the bills, with costs.
