None of the separate elements of the devices described in the
patent granted September 18, 1873, to John A. O'Haire and W. A.
Jones, as assignees of John A. O'Haire for an improvement in
operating car doors was new, nor was the combination new, nor was
there any patentable invention in the contrivance described in the
patent.
The device described in the patent granted March 30, 1876, to
appellant for an
Page 114 U. S. 150
improvement in signaling devices for streetcars required no
ingenuity, and cannot be called an invention.
The combination described and claimed in the patent granted
September 7, 1875, to appellant for an improvement in streetcars is
a mere aggregation of separate devices, each performing the
function for which it is adapted when used separately, and the
whole contributing no new result as the product of the joint use,
and it is not a patentable invention.
John Stephenson, the appellant, was the plaintiff in the circuit
court. He brought his bill to restrain the infringement by the
Brooklyn Crosstown Railroad Company, the appellee, of three letters
patent. The first was a patent dated September 16, 1873, granted to
John A. O'Haire and W. A. Jones, as assignees of John A. O'Haire,
the inventor, for "an improvement in operating car doors." The
second, dated March 30, 1875, was granted to the appellant "for an
improvement in signaling devices for streetcars." The third, dated
September 7, 1875, was also granted to the appellant for an
"improvement in streetcars," consisting in placing a mirror in the
hood of an ordinary streetcar to enable the driver to see what was
occurring in and behind the car.
The bill charged an infringement of each of these patents by the
appellee in all of its cars.
The answer of the appellee denied infringement of any of the
patents sued on; averred that all had been anticipated by specified
American and foreign patents and by certain persons in this
country, naming them; that none of the devices was patentable, and
that the devices described in the second and third patents were in
public use and on sale for more than two years prior to the
application for letters patent therefor respectively.
Upon final hearing, the circuit court dismissed the bill, 14 F.
457, and the plaintiff appealed.

MR. JUSTICE WOODS, after making the foregoing statement,
delivered the opinion of the Court.
We shall consider each of the patents in the order above
stated.
The invention described in the O'Haire patent consists of a
combination and arrangement of devices by which the rear door of a
streetcar can be opened and closed by the driver from the front
platform where he stands, in order to let passengers into or out of
the car. The drawing by which the specification is illustrated
shows the frame of an ordinary streetcar provided with a door which
is supported upon and moves back and forth upon suitable pulleys
and ways, which, it is said, may be arranged in any desired manner.
Passing through the bar from which the hand straps are suspended,
and which is made hollow, is a rod or rockshaft which has a lever
or crank upon its front end within easy reach of the driver. Upon
its rear end is a similar lever or crank carrying a roller, which
works up and down in a rectangular guiding frame secured to the
rear edge of the door, and by which the door is opened and closed.
The driver, by a slight push upon the front lever, can open the
door, or by a pull toward him can close it without moving off his
seat.
The claim is as follows:
"The rod
i, crank or lever 3, and guiding frame 6,
secured to the door and combined with an operating lever for the
driver, substantially as shown and described."
The infringement charged against the defendant was the use of
cars containing an "improvement in operating car doors," described
in the patent of George M. Brill, dated December 1, 1874. The
device covered by this patent was substantially the same as that
described in the O'Haire patent, except that the rockshaft ran
along the bottom of the car instead of through the bar from which
the hand straps were suspended.
There is no evidence to show that O'Haire's invention antedates
the application for his patent, which was made on June 27, 1873.
Considering the state of the art at that time, we are of opinion
that the device covered by his patent does not embody anything new
which the defendant infringes. The opening
Page 114 U. S. 152
and closing of the rear door of a streetcar from the front
platform is not new. The specification of the O'Haire patent
says:
"I am aware that it is not new to operate the door from the
front platform of the car, as this has heretofore been accomplished
by means of an endless cord which passes through the rods to which
the holding straps are secured, and I therefore disclaim such
invention."
At the date of O'Haire's application, it was well known, as is
shown by the evidence, that doors and window shutters guided by
slides, both in vehicles and apartments, were opened and closed by
mechanism used by persons placed in such situations that they could
neither reach nor open and close the doors or shutters directly.
The device of O'Haire must therefore, to be the subject of a valid
patent, embody some new means for accomplishing this end.
The elements of which his contrivance was made up were the rod
or rockshaft, reaching from the front to the rear of the car, the
lever by which a rocking motion was given to the shaft, and the
means used for communicating motion from the shaft to the door.
The testimony is conclusive to show that there is nothing new in
the rockshaft or in the lever by which it is moved. Long before the
date of O'Haire's application, the evidence is clear that
rockshafts operated by a lever or crank were used to open and close
the doors of furnaces, and the window and door openings of sugar
refineries, by persons standing at a distance from the windows and
doors to be opened and closed. A rockshaft moved by a lever at the
end of a railway carriage for the purpose of opening and closing
the sliding doors of the carriage was described in the English
letters patent set out in the record of John Johnson, dated March
3, 1857. The use of a rockshaft for a similar purpose, namely, the
opening and closing of sliding window blinds, is also shown in the
patent of David Kidder, dated June 8, 1869. Rockshafts for the same
purpose are shown in the patent of Darwin D. Douglass dated June
11, 1861, and the patent of W. H. Brown dated February 23, 1864.
The shaft in the Brown patent was moved by a lever, and in the
Kidder and Douglass patents by a knob attached
Page 114 U. S. 153
to its end, which is the well known equivalent of a lever. It
appears, therefore, that the use of a rockshaft actuated by a lever
for communicating motion was an old device which had been in use
long before the date of the O'Haire patent.
It remains to consider the mode adopted by O'Haire for
communicating motion from his rockshaft to the door of the car. We
find it to be one of a number of old and well known devices for
changing rotary into horizontal or rectilinear motion. The
testimony shows that the devices long used for this purpose are a
pinion or segment a pinion whose teeth interlock with the teeth of
a straight bar or rack or a rigid lever attached at one end to the
rockshaft and having on the other a pin or roller working in a slot
formed on the door or shutter to be moved. Sometimes the slot is in
the lever and the pin or roller is on the door or shutter. These
devices perform the same functions in substantially the same
manner, and have long been recognized as mechanical equivalents.
The device covered by the patent of O'Haire therefore consists of a
rockshaft with a lever attached for the purpose of giving the shaft
a rocking motion, combined with a well known and long used device
by which the rocking motion was changed into a rectilinear motion
and communicated to the door of a car. No one of these devices can
be claimed as new.
If there is any ingenuity displayed in the contrivance described
in the O'Haire patent, it must therefore be in the combination of
these devices to attain a result. The claim of the patent is for
such a combination. But in our opinion, this combination was
anticipated by the patents of both Douglass and Brown before
mentioned.
The inventions described in these patents are for the opening
and closing of outside shutters from the inside of a house without
opening the windows, and they consist of a rockshaft passing
through the wall of the house, to which a rocking motion is
imparted from the inside of the house, in the one case by a knob,
and in the other by a lever or handle on the inner end of the
shaft. By means of a pinion on the outer end of the rockshaft,
applied to a toothed rack on the shutter, a rectilinear sliding
motion is imparted to the shutter, which is thus
Page 114 U. S. 154
opened and closed. The rockshafts in these patents are identical
with the rod or shaft in the O'Haire patent; the lever in the Brown
patent, by which the rockshaft is moved, is the same as the lever
in the O'Haire patent, and the knob in the Douglass shaft is its
well known equivalent, and the contrivance by opinion and rack for
transmitting motion from the rockshaft to the shutter is the well
known and long used equivalent of the devices used for a similar
purpose in the O'Haire contrivance. We find, therefore, that none
of the separate elements of the devices described in the O'Haire
patent is new, nor is the combination new. So far, therefore, we
find no patentable invention in the contrivance described in the
patent under consideration. It was said by this Court in
Smith v.
Nichols, 21 Wall. 112, that
"A mere carrying forward a new or more extended application of
the original thought, a change only in form, proportions, or
degree, the substitution of equivalents, doing substantially the
same thing in the same way by substantially the same means, with
better results, is not such invention as will sustain a
patent."
So in
Pennsylvania Railroad v. Locomotive Truck Co.,
110 U. S. 490, MR.
JUSTICE GRAY, delivering the opinion of the Court, said:
"The application of an old process or machine to a similar or
analogous subject, with no change in the manner of application and
no result substantially distinct in its nature, will not sustain a
patent even if the new form of result has not before been
contemplated."
These authorities are pertinent.
See also Vinton v.
Hamilton, 104 U. S. 485;
Blake v. San Francisco, 113 U. S. 679.
If, therefore, there is any patentable novelty in the O'Haire
contrivance, it is in the placing of the rockshaft inside the bar
to which the hand straps are attached. But the plaintiff's counsel,
in order to bring the device used by the defendant within the
monopoly of the O'Haire patent, insist that this is no part of the
patented contrivance, and the testimony shows that the defendant
does not use it.
We are of opinion, therefore, that, construing the patent of
O'Haire in view of the state of the art at the date of its issue,
as we are compelled to do in order to leave any ground whatever on
which it can be sustained, the defendant does not infringe.
Page 114 U. S. 155
We have next to consider the patent granted to the plaintiff,
dated March 30, 1875, "for an improvement in signaling devices for
streetcars."
The specification thus states the object of the contrivance
described in the patent.
"The prevalence of streetcars managed by the driver without the
aid of a conductor makes it necessary that every possible facility
should be provided for him as well as the passengers."
"The ordinary streetcar has a signal bell located at each end,
with a bell strap attached thereto, which runs centrally along the
ridge or highest part of the ceiling. This strap, as thus located,
is inaccessible to many passengers. My improvement is intended to
remedy this trouble, and consists in a new combination and
arrangement, with a streetcar, of bells or gongs and of the cords
or straps which operate them, whereby passengers can, without
rising from their seats, signal to the driver. This is of primary
importance to invalids, ladies, and children, and that more
especially when the car is crowded."
The device covered by the patent consists of the placing of two
bells attached to the rafters of the bonnet or hood of the driver's
platform, one at each corner of the front end of the car. To the
hammer of each bell is attached one end of a bell cord, the other
end of which is attached to the inner side of the rear wall of the
car, the cords being led along the lower margin of the ceiling, one
on each side the car, from which bell pulls or hand straps are
suspended at intervals within easy reach of the seated passengers,
so that they, without rising from their seats, can ring the
bell.
The claim was as follows:
"In a streetcar, two bell cords, each provided with a system of
pull straps and arranged in such manner as to pass along the lower
margin to a bell or gong attached to the outside of the driver's
end of the car, substantially as and for the purposes set
forth."
We are of opinion that there is no patentable invention
described in this patent. Bell straps or cords running from one
Page 114 U. S. 156
end of an omnibus or streetcar to the other, under the middle of
the ceiling, were well known and in common use years before the
application of Stephenson for his patent. The fact that they were
so placed and used is mentioned in the specification. The evidence
also establishes the fact that before the year 1870, it was a
common practice to attach pendant bell pulls or hand straps to this
central cord so as to bring it within easier reach of the
passengers. The evidence shows that many of the cars in which such
hand straps or bell pulls were used were built and sold in New
York. The use of such pendant hand straps long before the
application of Stephenson for the patent now under consideration is
conclusively proven.
It is also shown by the evidence that as early as the year 1861
a bell cord or strap running along the sides of the cars above the
heads of the passengers was publicly used on streets cars in Boston
and Philadelphia, and the same arrangement of the cord or strap was
shown in the patent of Charles Carr, issued July 5, 1870. When,
therefore, the patent of Stephenson for his improvement in
signaling devices for streetcars was applied for in March, 1875,
the only advance in the art which his specification showed was the
applying to the cords running along the sides of the cars of the
bell pulls or hand straps which had before then been attached to
the cord running over the middle of the aisle. This, in our
judgment, did not require the least degree of ingenuity, and cannot
be called invention.
Hotchkiss v.
Greenwood, 11 How. 248;
Stimpson
v. Woodman, 10 Wall. 117;
Atlantic Works v.
Brady, 107 U. S. 192;
Slawson v. Grand Street Railroad Co., 107 U.
S. 649;
King v. Gallun, 109 U. S.
99;
Phillips v. City of Detroit, 111 U.
S. 604. The patent, therefore, by which the plaintiff
seeks to embrace in his monopoly such an arrangement of the signal
cords and hand straps of a streetcar is void.
The third patent which the plaintiff avers is infringed by the
defendant is for the improvement in streetcars granted to John
Stephenson, the appellant, September 7, 1875, on an application
dated August 7, 1874. It is thus described in the
specification:
"In running streetcars, it has been found to be a serious
Page 114 U. S. 157
source of trouble to have the driver continually turning around
to ascertain when it is necessary to stop to permit passengers to
enter or leave the car, as such constantly takes away his attention
from his horses, and that frequently when it is most required. To
obviate this trouble is the object of my present improvement. My
invention for this purpose consists in combining a mirror with the
front hood of the car, it being so arranged in connection therewith
and with an opening in the front end of the car as to give to the
driver a clear view of the inside of the car and through the
entrance door of the latter, and that without the necessity of his
having to turn around for such purposes, thereby enabling him,
without withdrawing his attention from the horses, to see when it
is necessary to stop, either to receive a passenger or to allow one
to get out. This mirror is set at a small angle to a horizontal
plane so that its upper edge will project rearwardly beyond its
lower edge, it being placed at such angle as will enable it,
through the opening F in the front end of the car to give the best
view of the interior of the car, and through the glass windows of
the entrance door A."
The claim was as follows:
"The combination of a bonnet E, provided with a mirror C with an
opening, or an opening covered by a transparent medium F in the
front end of a streetcar, substantially as and for the purposes set
forth."
A combination is patentable only when the several elements of
which it is composed produce by their joint action a new and useful
result or an old result in a cheaper or otherwise more advantageous
way. The elements of which the combination described in this patent
is composed were all old and well known. They were a mirror, the
hood of a streetcar over the driver's platform, and a glass panel
in the front end of the car over the door. We are of opinion that
the alleged combination of these three elements as described in
this patent is not patentable. There is in fact no combination, but
a mere aggregation of separate devices each of which performs the
function for which, when used separately, it was adapted, and does
not contribute to any
Page 114 U. S. 158
new result, the product of their joint use. The result attained
is merely the reflection of an object in a mirror. The hood and the
glass panel in the end of the car do not change in any degree the
function of the mirror. It is used as a mirror only. The function
of the hood is not changed by the mirror or glass panel, or both.
It is a hood only on which, as in the wall of a room, the mirror is
hung. The use of a glass instead of a wooden panel in the front end
of the car simply removes an opaque obstacle between the mirror and
the object to be reflected by it. Neither one of the three elements
of the alleged combination performs any new office or imparts any
new power to the others, and combined they do not produce any new
result or any old result more cheaply or otherwise more
advantageously. There is therefore no patentable combination.
This conclusion is illustrated and confirmed by the following
cases:
Hailes v. Van
Wormer, 20 Wall. 353;
Reckendorfer v.
Faber, 92 U. S. 347;
Pickering v. McCullough, 104 U. S. 310.
It results from the views we have expressed that the decree of
the circuit court dismissing the bill was right. It is
therefore
Affirmed.
