Opinion

KNAPPEN, Circuit Judge.

Suit for infringement of Ehrlich patent, No. 560,089, May 12, 1896, for cash register, indicator, and check-printer. Defendant is sued as a user of a Hailwood cash register. The District Court dismissed the bill for lack of infringement, and appeal is taken from that decree. Defendant also appeals from an order hereafter referred to.

[1] The Ehrlich device, broadly speaking (and disregarding the registering and printing mechanism), embraces an oscillatory rotatable horizontal cylinder operated by a “motor” in the form of a coiled spring and connecting shaft. This cylinder operates by means of a bevel-gear, an upright shaft having upon its upper end a sleeve carrying an indicator wheel; the wheel and" shaft being capable of turning independently of each other. The cylinder is held in initial position by a detent. The indicator bears numbers on its periphery, each number corresponding to a key in the form of a push-pin upon the face of the lower part of the machine-frame. The depression of any one of this series of keys directly releases the motor-detent and allows the cylinder to turn under the influence Of the motor-spring, until arrested by one of a series of stop-pins upon the cylinder surface contacting with the end of the depressed push-pin. The movement of the cylinder also produces a rotation of the indicator sufficient to bring into view, through an opening in the machine case, the number corresponding to the key depressed. The same operation of any one of this series of keys releases the cash drawer, the closing of which rewinds the motor-spring, restores the motor and cylinder to their original position, releases the previously depressed key, and restores it to its normal position for another operation. The claims sued upon are Nos. 1, 2, 18, 19, 24, 25, 36, and-37. Claim 1 is as follows;

“1. Tlie combination of a motor, an oscillatory member actuated thereby, means for holding the motor in check, a series of keys controlling said means and co-operating with the oscillatory member to arrest the latter at different points [whereby upon operating any key in the series the motor will be released and the oscillatory member moved by it until arrested, by the operated key] and (means for restoring said member to initial position and winding up the motor).”

[465] Claim 2 differs from claim 1 in omitting the bracketed portion above, and in place of the words in parenthesis substituting “a money -drawer and connections for restoring the oscillatory member to initial position and winding up the motor.” Claims 19, 36, and 37 each include'a detent for holding the motor in check, and a series of keys controlling the detent.

Defendant’s machine differs from the Ehrlich device in several respects. Instead of one indicator, it has four indicators, each of which is actuated by its own separate mechanism and bears its own series of figures; each number on which is represented by its own separate key, likewise in the form of a push-pin. The actuating mechanism for each indicator embraces a notched or shouldered segment (oscillating) mounted on a horizontal shaft. The motor consists of a weighted frame attached to the shaft and operated by gravity, slightly aided by coiled springs. The depression of any one of a series of push-keys releases a hook from engagement with a projection on the lower part of the segment, and interposes the appropriate pin in the path of one of the shoulders thereon. It has, however, no effect upon releasing the motor and does not advance the segment which actuates the indicator. Such release is effected only by depressing a key entirely separate and independent from the series of keys referred to, whereby a detent which holds the drawer in its closed position is released, the motor being thereby released and advancing the segment until its shoulder contacts with the appropriate push-pin. The closing of the money drawer winds up, or restores, the motor and withdraws the push-key from its depressed position. It will thus be seen that defendant’s machine entirely lacks the element of a motor-detent controlled by a series of keys, the depression of any one of which moves the indicator, as the direct result of the releasing of the motor-detent. This feature is one of the prominent elements of the Ehrlich device. The specification says:

“The motive power of the machine is a coiled spring, which is wound up by the closing of the money-drawer. This motor is held in cheek by a detent which is controlled by a series of keys. When any one of said keys is operated, the motor is released and moves the indicator, register, and type-wheel distances corresponding to the value of such key to indicate and register such value and set the type-wheel to print it.”

[2] This method of key control is not given as a preferred form. A claim for combination is not infringed if any one of the elements is omitted without substitution of an equivalent.

A. 204. Whether defendant’s machine infringes the claims under consideration thus depends on whether the detent-releasing mechanism of defendant’s machine is the equivalent of Ehrlich’s mechanism; and this question in turn depends upon the state of the art prior to Ehrlich, and the advance made by him.
