U.S. Supreme Court Stephenson v. Brooklyn Crosstown Railroad Co., 114 U.S. 149 (1885)
Stephenson v. Brooklyn Crosstown Railroad Company
Argued March 11, 1885
Decided March 23, 1885
114 U.S. 149
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
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
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
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
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."
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.
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
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
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
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.
It results from the views we have expressed that the decree of the circuit court dismissing the bill was right. It is therefore
