Opinion

Shipman, J.

This is a bill in equity to restrain the defendants from the infringement of reissued letters patent No. 10,162, issued March 14, 1882, to Arthur E. Hotchkiss, for improvements in clock movements. The original patent was dated November 4, 1879. The application for the first reissue, No. 9,656, granted to said Hotchkiss April 12, 1881, was filed in the patent-office January 22,1881. The application for the present reissue, No. 10,162,'was filed July 19, 1881. The Parker & Whipple Company are exclusive licensees under the original and reissued patents. At the date of the invention expensive clocks of tiny size were being made, which met with favor from the public. They were convenient and attractive, and the main object of the patentee (the original specification says a leading object) was to make a good time-keeping clock of the like small size, which could be furnished to the public at the small price which characterizes the manufacture of Connecticut clocks. The clock was devised for this end, unquestionably with much study and painstaking, and I shall assume that the invention as claimed in the reissue was both novel and patentable. Much skill and ingenuity have been displayed in attacking and defending these contested points, but as I think that a vital point of the plaintiff’s case depends upon the validity of the reissue, I shall confine myself to that question.

[44]*44The patentee, in his original specification, stated the nature of his invention as follows:

“ This invention relates to that class of time-Ireepers in which a fixed annular rack or internally toothed wheel is employed to aid a spring barrel in rotating the train of wheels. The nature of said invention consists, partly, in the combination of a fixed internally toothed circular rack and a concentric going barrel or plate with a mainspring, a transiñitting wheel rotating with said barrel, and a fixed clock movement. It also consists in arranging the operating parts of the time-piece on a fixed plate, and attaching the same to the back of the clock-case by means of tongues which extend out from said plate through perforations in the back of said case. It also consists in providing said tongues with broad shoulders, which cause said plate to stand out fiom the back of the clock-case, so as to leave space for the mainspring between them. It also consists in the combination of a mainspring having a perforated end with a lateral finger extending from the broad part of one of said tongues, whereby said mainspring is firmly held at its fixed end, yet easily detached. It also consists in the combination, with a fixed plate, which confines the mainspring and supports the movement of a rotating plate arranged in front of said fixed plate, and provided with a hub which extends through said fixed plate and' is connected to the winding end of the mainspring. It also consists in adapting to and combining with the hub thus constructed a key having a screw-threaded winding part for engaging with said huh, and a recessed part for engaging with the prismatic end of the center shaft. It also consists in constructing the annular rack or internally toothed wheel with an annular recess for receiving the pillar plate and thereby economizing space. It also consists in constructing the pillar plate and pillars in one piece, and attaching said pillars to the front plate by twisting them. It also consists in substituting an automatic winding dog, operating like an escapement verge, for the click and spring ordinarily used. It also consists in constructing the case with an opening at the bottom, and adapting the key and the adjusting nut of the pendulum hall to one another, so that the adjustment of the said ball may be effected conveniently from the outside of the case. It also consists in providing said ball with a spring which will force it down into place, and with a guide which will prevent it from turning.”

The 12 claims of the original patent were confined to these details thus enumerated in the specification-.

In March, 1880, the Parker & Whipple Company entered into a contract with the Yale Clock Company to manufacture the Hotchkiss clock, at a stipulated price per clock, the licensees furnishing the dies and tools for such manufacture. About 50,000 clocks were made by tlie defendants and delivered to the licensees between June 17 and December 27, 1880. During this period the defendant Frederick A. Lane, superintendent of the Yale Clock Company, made the infringing clock. It did not contain a single patented feature of the Hotchkiss clock, but in respect to every other leading feature the parts of the two clocks are interchangeable. The Lane clock was immediately patented, was put upon the market, and is being manufactured by the Yale Clock Company.

An examination of the Hotchkiss patent showed tbat the vital parts of the invention were not alluded to in the specification or in the claims. Perhaps the fact that the clock had three wheels, [45]*45and ilieir position, might have been understood by an export from, drawing No. 6. That drawing was not made for the purpose of showing the wheels, and it is manifest from the specification that the patentee did not suppose they had anything to do with his invention, which he did suppose lay in entirely other parts of the clock. The model showed a completed clock, and contained whatever was and was not invented by Hotchkiss.

In the specification of the second reissue, the patentee omitted the entire description, which has been quoted and inserted in the following:

•• My invention relates to an improvement in clock movements, the object being to make a clock movement which shall be simple and durable in its construction, of small initial cost in manufacture, and the several parts of which shall be relatively arranged in such manner that the movement may be inclosed in a small and compact case. To this end the invention consists in dividing the train into two parts; in arranging the divisions of the train in a frame having three plates; in providing an additional wheel and pinion between the escape wheel and center wheel; in making the three wheels between the escape wheel and center wheel with the same number of teeth and of the same size; in arranging the pivots of the three arbors carrying the three like wheels and pinions between the escape wheel and center wheel in the circumference of circles which are concentric with the center arbor; and in other minor improvements as the invention is hereinafter more fully described and explained by reference to the drawings.”

In accordance with this statement the plaintiff’s experts claimed upon the trial that the invention consisted generally in the division of the train into two parts by means of a frame having three plates, the point of division being between the center wheel and the center pinion; and, secondly, in the arrangement, between the center wheel and the escape wheel, of three wheels which are driven by the center wheel in the circumference of a circle which is concentric to the center arbor, the three wheels being arranged on a semi-circle concentric to the ceuter pinion. This general outline of the invention is stated with accuracy and completeness in eight claims of the reissue, four of which relate to the division of the train into two parts in a frame having three plates, while the other four relate to the arrangement of the three wheels. The tenth and eleventh claims relate to details which were specified in the original patent, but which are not used by the defendant. The defendants infringe the first eight claims.
