When, in a suit in equity for the infringement of letters
patent, the court below makes an interlocutory decree in
plaintiff's favor, and then entertains a motion for a rehearing and
receives affidavits in support of it, and denies the motion, this
Court does not feel itself at liberty to consider those
affidavits.
The first claim in letters patent No. 218,300, issued August 5,
1879, to William Mills and Christian H. Hershey, for an improvement
in haircrimpers,
viz.:
"A hair-crimper consisting of a nonelastic metal core C, and
braided covering A, said covering A being cemented to said core C
throughout its entire length, substantially as described,"
is void for want of novelty.
This was a bill in equity brought by Heysinger and one Christian
H. Hershey, now represented by the administrator of his estate,
against the appellants, trading under the name of Noyes, Smith
& Co., to recover damages for the infringement of letters
patent No. 218,300, issued August 5, 1879, to William Mills and
Christian H. Hershey, for an improvement in hair crimpers.
In their specification, the patentees state that
"this hair crimper is intended to be applied to the hair in the
manner of the crimping papers formerly in common use, the ends
being turned under out of sight, and the hair retained by the folds
thus made."
"It consists essentially of a strip of soft, nonelastic metal,
preferably flat, covered with a fibrous coating, cemented thereto,
so that when cut into proper lengths for use, the ends
Page 150 U. S. 628
will not fray out, but remain the same into whatever number of
pieces the crimper may be divided, thus rendering it specially
adapted for use with children, where crimpers of different lengths
are often required, while at the same time greatly simplifying and
cheapening the cost of manufacture."
The crimper consists of a core of what is known as "gardeners'
lead," which is passed in long strips through a liquid cement known
as "dextrine" and is then wound about by a braid of fibrous
covering, and the adhesive material taken up in the passage through
it of the leaden core is thus interposed between the fibrous
covering and the soft metal core, making an adhesion between them,
while leaving the outer surface of the braid soft and
unsaturated.
"Were the fibrous surface thoroughly saturated with adhesive
matter, the crimper would be comparatively useless, as the least
moisture in the hair would cause its adhesion thereto."
The article is manufactured in long strips, which are laid away
and dried, after which they are run through a cutting machine,
which cuts the strip into pieces of equal length, laying them out
in dozens, which are then bundled and boxed for the market.
The first claim of the patent -- the only one charged to have
been infringed -- reads as follows:
"A hair crimper consisting of a nonelastic metal core, C, and
braided covering, A, said covering, A, being cemented to said core,
C, throughout its entire length, substantially as described."
Upon the hearing in the court below, a final decree was entered
for $360.85, with costs, from which decree defendants appealed to
this Court.
MR. JUSTICE BROWN, after stating the facts in the foregoing
language, delivered the opinion of the Court.
This case was defended upon the ground that one Gilbert H.
Blakesley, the real defendant in the case, long before this
Page 150 U. S. 629
patent was issued, manufactured hair crimpers in substantially
the manner specified in the patent. The substance of the testimony
in this connection is that, in the latter part of 1875, one Julius
Wright, whose principal business was the manufacture of garters at
Bristol, Connecticut, began the manufacture of hair crimpers by
rolling a sheet of copper to the proper thickness, putting it upon
a reel, and braiding it with silk. "Then," says he,
"I had this taken off a reel, and stretched out on a bench, and
at certain lengths that I wanted to cut the crimps I used the
dextrine with a brush, for the same purpose that we did for cutting
up the garter -- that is, to assist in cutting up. Then, those that
I made, I made a little brass tip, as I called it, which I put on
to give the crimper a finish, or ornament, whichever might be
proper."
He states the object of applying the cement to have been "to
adhere the silk to the metal, and stiffen it, so as to cut it." He
was engaged in this way for one or two months, and made up about
thirty gross of crimpers. The dextrine was laid on at intervals of
about two and a half inches, and the advantage of using it seems to
have been to facilitate the cutting of the crimpers at these
points, and providing them with a silver-plated clip at each end.
It was not claimed that Wright cemented the braided covering to the
core "throughout its entire length," as specified in the first
claim of the patent.
He further testified that Blakesley took up the business in the
spring of 1876 by passing the strips of metal up through a dish of
dextrine, after which it was braided with silk. He says the metal
was not covered when it entered the dish, but it looked wet and
discolored as it emerged, and that the effect of passing the strip
through the cement or dextrine, and then applying the silk
covering, would be to secure the covering to the metal. Blakesley
stated the process as follows:
"I directed a plain strip of brass through a dish of dextrine
provided with a roller journaled in a dish, thereby to immerse the
strip, passing it to the braider while wet with cement, to which
the silk cover adhered throughout the length of the strip. I then
cut them up at any point I desired."
He judges that he made some fifty gross or more in this way, and
then
Page 150 U. S. 630
changed his plan by making them with a double covering.
"I first covered the plain strip of metal with cotton, the strip
being dry. I then conducted the cotton-braided strip through the
silk braider, applying a cover of silk. The cotton-covered strip
was conducted through a dish of dextrine under a roller journaled
in the dish, thence to pair of stripping rolls situated between the
dish and the braider, this dextrine saturating the cotton
thoroughly throughout its length, the stripping rolls depriving it
of the surplus cement, leaving it wet and thoroughly saturated, and
wet enough to receive the silk covering and cement it, so that all
three -- core, cotton cover, and silk cover -- were cemented
together. They were cut up and packed as before."
The court below held, with regard to the double cover process
used by Blakesley, that the braided covering was immersed in the
dextrine,
"not in order to cement it to the core, but to enable the
material to be cut without fraying out. The adhesion of the strands
together, and not their adhesion to the core, was the object he had
in view."
The court, however, regarded the theory that Blakesley made
crimpers also by immersing a strip of metal in dextrine and then
covering it, as refuted by the omission of both Blakesley and
Wright to mention the fact in their affidavits used to oppose a
motion for a preliminary injunction, as those affidavits purported
to give a full history of the manufacture of crimpers by Blakesley,
"and the omission to state what was so important, if true, is
significant."
Acting upon this theory, the court directed an interlocutory
decree for the plaintiffs. Defendants thereupon moved immediately
for an order to reopen the case for the admission of additional
testimony bearing upon the question of anticipation, and for a
rehearing, and presented seven affidavits in support of Blakesley's
testimony concerning the manufacture of crimpers by passing a bare
strip of metal through the dextrine before the silk braid was
applied, and also the affidavit of his counsel, explaining the
omission of the mention of this particular in the affidavits of
Wright and Blakesley, read in opposition to the motion for a
preliminary
Page 150 U. S. 631
injunction. The court denied a rehearing, and the case was
referred to a master, who proceeded to take testimony in respect to
the damages, and submitted a report, upon which a final decree was
entered. Under these circumstances, we have not felt at liberty to
consider the affidavits for a rehearing.
But, assuming that the court was correct in its conclusion that
the testimony of Wright and Blakesley with respect to the process
of immersing the bare strip of metal in the dextrine and then
covering it should be disregarded by reason of their omission to
mention the fact in their affidavits to oppose the injunction, the
question still remains whether the process about which they did
testify, and which it is admitted Blakesley did adopt, was not a
substantial anticipation of the Mills and Hershey patent. This,
which is known as the "double cover process," consisted in covering
the plain strip of metal with cotton and conducting the strip so
covered through a dish of dextrine under a roller journaled in the
dish, and thus saturating the cotton thoroughly throughout its
length; thence to a pair of stripping rolls which deprived it of
the surplus cement, when the cover was braided on, so that, as he
states "all three -- core, cotton cover, and silk cover -- were
cemented together." Blakesley states that the cotton strands did
not make as compact a braid as silk, but left the meshes somewhat
open, so as to allow the cement to circulate more freely through
the covering. If, as he states to have been the case, the
saturation of the cotton was so thorough that all three -- core,
cotton cover, and silk cover -- were cemented together, it is
difficult to see why this process did not cover everything that is
claimed for the Mills and Hershey patent. The advantage of
cementing the braid to the core throughout its entire length is
stated in their patent to be "so that, when cut into proper lengths
for use, the ends will not fray out, but remain the same, into
whatever number of pieces the crimper may be divided," while the
outer surface of the braid is left soft and unsaturated.
This was precisely the object sought to be accomplished, though
for a temporary purpose, by Wright, in his first experiments,
Page 150 U. S. 632
by applying dextrine to the braided covering at intervals of two
or three inches, and by Blakesley in the several processes used by
him, including the one which is charged to be an infringement, and
which consists in enclosing the metal core in long strips of paper
passed through a bath of dextrine before the braided covering is
applied. But whether Blakesley applied the dextrine to the bare
metal in the manner described in the Mills and Hershey patent, or
to the metal after it was covered with the cotton braid, makes
apparently little practical difference with respect to fraying out,
and was a matter which rested in the judgment of the manufacturer.
If either plan were known, the adoption of the other would involve
no invention, the dextrine in both cases being used for the same
object -- namely, to prevent the silk braid from fraying at the
point where it is cut. It was a matter of simple mechanical skill
to determine whether that object were better accomplished by
running the bare metal or the covered metal through the dextrine
before the outer braid of silk was applied. If the meshes of the
cotton were loose or open, the adhesion of the core would be amply
sufficient to prevent the fraying out, which it was the object of
the patent to accomplish. The bath of dextrine was the essential
feature of both devices, and even if the double cover were less
efficient than the other, it required no exercise of the inventive
faculty to omit the cotton cover and immerse the bare metal.
It is evident that if Mills and Hershey had been the first to
use the process described in this patent, of immersing the bare
metal in a bath of dextrine and then covering it with a fibrous
coating, the double cover process of Blakesley would have been an
infringement. The intervention of a loose cotton covering between
the outer braid and the bare metal would have been treated simply
as an evasion.
In an examination made of the plaintiffs' and defendants'
exhibits put in evidence in this case, it appears in fact there is
very little adhesion between the covering and the core in the
plaintiffs' device, and none at all in the defendants', though it
is possible this may be due to their age. Such adhesion as there is
in plaintiffs' crimpers seems to be due rather to the
Page 150 U. S. 633
pressure of the braid upon the core than to the use of an
adhesive material.
The decree of the court below must be
Reversed, and the case remanded, with directions to dismiss
the bill.
