HANDLE STOP FOR AUTOGRAPHIC REGISTERS.

Application filed July 12,

To all whom it may concern:

Be it known that I, MILTON C. STERN, a citizen of the United States, res'ding at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Handle Stops for Autographic Registers, of which the following is a specification, reference being had therein to the accompanying drawing.

Th's invention relates to a handle stop for autographic registers and the like.

In autographic registers and other machines in which a feeding mechanism, or other part of the machine, is to be operated a predetermined distance upon each operation of the machine it is customary to provide an operatng crank having a handle provided with a stop to cooperate with a fixed stop mounted on the machine and thus check the movement of the crank at the end of a complete rotation thereof. To permit another operation of the crank the stop on the handle must be moved out of engagement with the fixed stop. This has been accomplished in various ways which are more or less awkward and inconvenient in their operation, as, for example, the movement of the handle transversely to the crank to. withdraw the pin, or stop, carried thereby beyond the end of the fixed stop.

The object of the present invention is to provide a handle stop of this character which will be so constructed and arranged that it can be very easily and conveniently operated to disengage it from the fixed stop.

A further object of the invention is to provide a device of ths kind which will be simple in its construction and operation and which can be manufactured at a low cost.

Other objects of the invention may appear as the device is described in detail.

In the accompanying drawings, Fig. 1 is a s de elevation of a portion of an autographic register showing my invention applied thereto; Fig. 2 is a plan vlew of the operating mechanism of such a register, including the handle and its stop; and Fig. 3 is a sectional view taken on the lm 33 of Fig. 2 and partly broken away.

In these drawings I have illustrated one embodiment of the invention and have shown the same as applied to an autographic register of a well known construction, butit will be understood that this particular embodiment has been chosen for the pur- 1920. Serial No. 395,512.

pose of illustrat on only and that the device may be applied to autographic registers of different types and to mechanisms of various kinds where such a stop may be useful.

The autographic register here illustrated comprises a main frame 5 having mounted therein a shaft 6 which carries two pin wheels 7, the pins of which are adapted to enter series of perforations arranged along the respective edges of the superimposed webs of paper which are to be actuated. Mounted on the shaft 6 is a gear 8 which is operatively connected through the medium of an intermediate gear 9, shown in Fig. 1, with a gear 10, mounted on a stud shaft 11, journaled in an elongated bearing 12 secured to the main frame 5. The character of the feed ng mechanism is such that a single rotation of the gear will advance the paper the correct distance.

The gear 10 is rotated by means of a crank arm 13 secured to the shaft 11 and having at. its outer end a handle 14. In order that the rotation of the gear 10 may be checked at the end of a complete revolution the handle 14 has secured thereto a stop, here shown in the form of a pin, 15, extending axially therefrom toward the main frame of the machine and adapted to engage a second stop, or pin, 16 rigidly secured to the main frame and arranged in the path of the pin 15. In order that the pin 15 which is carried by the handle 14 may be moved out ofline with the stop 16 to permit rotation to be imparted to the crank arm and the gear, the handle is mounted on the crank arm for lengthwise movement relatively thereto, thus enabling the stop 15 to be moved into an inoperative position by a natural and easy movement of the handle 14. In the operat on of an autographi-c register of this kind the operator usually stands alongside the register in the rear of the shaft 11, consequently, when he grasps the handle 14 for the purpose of actuating the feeding mechanism, it is a very easy and simple matter to. move the handle rearwardly at the same time that he exerts a downward pressure thereon, thus withdrawing the stop 15 out of alinement with the stop 16. The handle may be mounted on the crank arm in any suitable manner but I prefer to provide the arm with a slot 17 extending lengthwisethereof and to slidably mount the handle in this slot. To this end the handle is provided with a "circumferential groove which forms a reduced portion thereon, as shown at 18, in Fig. 3, which fits withn the slot-17, and which also providesflanges 19 which are arranged on opposite sides of the arm 13 and which serve to hold the handle against lateral movement relatively touthe arm. The handle is acted upon by a spring which tends to move it toward one limit of its movement in the slot 17, preferably toward the outer end of the slot, and a pin 20 carried by the arm 13 limits this outward move ment of the handle and positions the stop 15 in operative relation to the stop 16. This spring which actuates the handle may be arranged in any suitable manner, but, as here shown, the arm 13 is provided at the inner end of the slot 17 with a recess 21 and a co led spring 22 is mounted in this, recess, projects into the slot 17 and bears against the reduced portion of the handle 1%, thus tending to move the same toward and to hold the same in engagement with the pin, or stop, 20, at the outer end of the arm 13. When the handle has been retracted to permit the stop 15 to clear the stop 16, the crank arm will be rotated and during this rotation the inward pressure on the handle is released so that the spring will move the same outwardly to its normal, or operative, position. Should the operator maintain the inward pressure on the handle during the rotation of the device the direction of this pressure will be naturally reversed as the crank arm moves through the latter part 'of its movement, as it will be apparentthat the pressure on the handle necessary to impart thereto the latter part of its movement will be in an outward direction, thus preventing the operator from inadvertently retaining the handle in its retracted position and permitting the crank arm to move past the normal limit of its movement, as idefined by the stops.

The operation of the device will be readily understood from the foregoing description and "t will be apparent that it is very sim ple both in its construction and operation and that the operation is a natural one in the manipulation of the crank arm, thus facilitating the operation of the latter. Further, the construction is such that the device can be very easily manufactured and, consequently, can be produced at a lowcost. There are. no parts which may be easily broken orv d'sarranged and the movable stop will be automatically returned to its normal, or operative, position without action on the part of the operator.

While I have shown and described one embodiment of my invention, I wish it to be understood that I do not desire to be limited to the details thereof, as various modifica tions may occur to a person skilled in the art. Having now fully described my invention,

what I claim as new and desire to'secure by Letters Patent is 1. In a mechanism of the characterdescribed, the combination with a device to be operated compris'ng a shaft, of a device for actuating said shaft having means for interrupting the movement thereof at the end movement of the handle must be inwardly towards the shaft and the operator when it is desired to release the locking of the parts.

2. In a mechanism of the character described, the combination with a device to be operated comprising a shaft, of a device for actuating said shaft having means for interrupting the movement thereof at the end of each complete rotation of said shaft, said actuating device comprising i a crank arm forked at its outer end connected with said shaft, having a recess near its forked end, a handle slidably mounted in said slot and having a circumferential groove in which the prongs of said arm lie, a'spring seated in said recess and tending to move said handle toward the outer end of said slot, a part carried by said arm near the outer end there of to limit the movement of said arm by said spring, a stop carried by said handle, and a secondstop arranged in the path of the stop which is carried by said handle when. the latter is in its outermost position, the several parts being so arranged that the movement of the handle must be inwardly towards the shaft and the operator when it is desired to release the locking of the parts.

3. In a mechanism of the character described, the combination with a device to be operated compris'ng a shaft, of a crank arm connected with said shaft, and having a longitudinal slot,-.a handle having a reduced portion slidably mounted in said slot and having flanges arranged on the opposite sides of said arm, a spring tending to move said handle toward the outer end of sad slot, said arm having means to limit the movement of said handle by said spring, a stop carried by said handle, and a second stop arranged in the path of said first mentioned stop when said handle is in its outermost posit on.
