In August, 1900, when Pumphrey filed his application, the slot machine art, if it may be so called, had narrowed to a point where the field was limited to improvements directed to greater simplicity and durability.
“My invention,” said Pumphrey, “relates to coin-operated mechanism of a class adapted particularly for use in connection with ‘slot machines.’ _ In machines of this character the use of a coin for tripping a lock by its weight or the'momentum acquired in its passage through a chute ordinarily necessitates the employment of a locking mechanism, the co-operating parts of which must be extremely light, delicate, and sensitive to insure a proper response under the action of the inserted coin, and as these machines are usually placed out of doors, exposed to all changes in atmosphere and temperature, a disarrangement or break-down of such locking mechanism frequently occurs, causing the machines to be labeled ‘Out of order’ for a considerable length of time, which thereby increases the cost of maintenance and materially reduces the net earnings. It is the object of the present invention to obviate the difficulties above mentioned by effecting the release of the machine by means of a hand-lever acting through the medium of a coin. The use of such a lever for this purpose, provides the requisite power for operating a tripping device of simpler and heavier construction than is ordinarily employed, and thereby renders the same more efficient and capable of withstanding the wear and tear with little or no liability of disarrangement under ordinary conditions, and, furthermore, insures an immediate response and complete operation upon the insertion of a proper coin.”
The claims here in controversy are:
“5. In coin-operated mechanism, the combination of a pivoted coin-carrier and a pivoted coin-finder, both mounted upon a movable carrier, and relatively disposed to receive a coin between their adjoining faces, and means for rocking the finder and thereby transmitting motion to the carrier through the medium of the interposed coin.
“6. In coin-operated mechanism, the combination of a trip-lever and a coin-carrier and a coin-finder co-operating therewith through the medium of a coin, a movable carrier common to both the lever and finder, and actuating means for the finder.”
“24. In coin-controlled mechanism, the combination of a member to be actuated, a pivoted trip therefor, spring-sustained normally out of operative relation, a coin-carrier, and a pivoted coin-finder co-operating through the me*957 dium of a coin to adjust the trip into a path of travel including said member, and means for operating the coin-finder and advancing the trip into engagement with said finder.”
Some question arose as to whether the word “carrier,” in the last clause of claim 5, meant the “coin”-carrier or the “movable” carrier or support upon which the coin-carrier and the coin-finder are mounted; but an examination of trie file wrapper demonstrates clearly that the word in dispute meant the “coin”-carrier.
The prior art concededly includes four patents, to wit: Cochran, No. 440,570, November 11, 1890: Williams, No. 530,148, December 4, 1894; Williams, No. 580,478, April 13, 1897; and Cook, No. 627,685, June 27, 1899.
It is contended that a later Cook patent, No. 664,235, granted December 18, 1900, application for which was filed on February 15, 1900, should also be considered as in the prior art; but this patent must be excluded under the authority of such cases as Bates v.

Apparently the novelty of the invention in suit resides in the pivotal momrliug of the operating lever, the pivoting of the trip-lever and its combined coin-carrier, and the pivoting of the finder co-operating with the latter. According to claim 6 of the Pumphrey patent, the coin-carrier is pivoted, while in Cook it is not; and so in claim 6 there is a “movable carrier common to both the lever and finder,” while in Cook there is not any construction in which the trip-lever and the coin-finder are mounted upon a common movable support for their proper operation.
Without further elaboration, it may be said that claims 5 and 6 show these elements above noted over previous patents and thus in a new combination. The practical result is that when a coin is deposited, and the lever or push rod is actuated by hand, the coin-finder, coin-carrier, and trip-lever are moved together bodily with the support, whereby tiie trip-lever is advanced into engagement with the member to be actuated.
As the constant effort in the art was toward simplification of a mechanism composed of many details, this improvement was sufficient to constitute patentable novelty. But, in the effort to cover every conceivable point by making 27 -claims, the patentee probably overstepped the bounds in claim 24, and I think it is likely that this claim was anticipated by Cook, No. 627,685. Be that as it may, the claim, when read against defendant’s structure, must be strictly construed.
Infringement of claims 5 and 6 seems clear, but not so with claim 24. In defendant’s structure the trip-lever 15 is normally in its operative horizontal position, and no movement takes place when the coin is inserted; while in the structure of Pumphrey’s patent the converse is true, because the coin-finder engaging the coin in the coin-carrier acts directly thereon to rock the trip-lever upwardly. The patentee
In view of the above differences ip tire actions of the structure of the patent in suit and of defendant’s mechanism, it cannot be held that defendant’s ejector 15 is “spring sustained normally out of operative relation.” The spring 19 of defendant’s mechanism returns the carriage to its outermost position, and when in this position the finder or projection 1% of the finder 9, to which the lever lip of the ejector 15 is attached, engages the framework 1, so that the trip-lever is rocked upwardly into its normal horizontal position. The spring itself has nothing to do with positioning the ejector in the same sense in which the spring 7a of the Pumphrey patent operates to move the trip lever 7 downwardly, in which position it is “spring-sustained” out of the path of movement of the member to be operated until a coin has been inserted in the coin carrier and the coin is acted upon by the finder.
With a claim entitled to broader scope, this difference in operation might not escape infringement; but, restricting the claim (if valid) to what I think are its proper limits, there is no infringement of this claim.
Complainants may have a decree in accordance herewith, with half costs.
