keys hugs the latter at all times so that, after 1934. The general structure of that machine has the printing operation, it is motivated without been reproduced to some extent in the aeeom impact and hence reduces the noise and wear panymg drawings and requires descnption hereincident to the actuatlon of such an element in in only insofar as Such description will aid in structures where it is normally held in a far position and is then released or motivated to undelstandmg the addltlons tpmvements 40 perform the clearing operation. To these and that. I have now In tms mew-and re other ends, the invention resides in certain imferrmg partmularly to t .drawmgs i provements and combinations of parts, all as to Flgs' 1 2 thereof I intimates a casing will be hereinafter more fully explained the d1v1ded by a horizontal slot 2 lnto a lower base 45 novel features being pointed out in the claims Portion 3 and an upper housing overhanging at the end of this specificatio breast portion 4. The base portion 3 is provided In the drawings: with a table plate 5 constituting the bottom of Fig. 1 is a top plan view of a, h k it the slot. In the printing of a check, the latter 5 machine constructed in accordance with and is laid upon the table, thrust back into the slot illustrating one embodiment of my invention; and y m n of a p v b gauge m 6 Fig. 2 is a side elevation thereof viewed from positioned so that with the aid of a pivoted line the side of the main operating lever, namely, the gauge I the printing impression through the deright side; vices hereinafter described may be accurately Fig. 3 is a substantially central longitudinal placed on the amount line of the check. This 55 the return movement of this operating lever that accomplishes that result.

In the general operation of the machine, when the operating lever 26 is brought forward from the position of Figs. 1, 2, 3 and 5, it being assumed that appropriate types on the various segments 9 have been brought into the printing line opposite the impact of the platen l5, the latter is raised from the position of Fig. 3 to that of Fig. 4 in the ordinary manner through the mechanical connections previously described. This forward movement of the operating lever is an idle one so far as the draw bar 38 is concerned because the plate on the same operating shaft 22 and its pin 36 is moving forwardly on the riding surface 46. The limit of the forward movement of such operating crank 20 is shown in Figs. 4 and 6. The arrival at this forward position results in the forward advance of pin 36 on member 35 on the operating shaft 22 and the dropping of draw bar 38 to the extreme low position of Fig. 4, incidentally bringing shoulder 4| on the draw bar in the direct path of such pin 36 on its return. When the latter so. returns with the operating lever, it engages and interlocks with shoulder 4| on the draw bar, as shown in detail in Fig. 8, dragging the latter rearwardly and with it the clearing yoke 33--34 which it positively actuates in this respect. The result is that the clearing and resetting yoke picks up successively or simultaneously, according to their previous adjustment, all of the radial key levers 28 of the various type segments and thrust them back to the normal position of Figs. 3 and 5 augmented by the action of the yoke spring 51 or at least not opposed thereby. When such a sufficient actuation of the draw bar has been accomplished, the

length of the riding surface and its relation to the shoulder 4| in agreement with the movement of the pin 36 is such that just as the draw bar, through its wrist pin connection 31, carries the clearing yoke 3334 to restore the type keys and levers to neutral position, the pin 36 rides below the shoulder 4| in the pins downward and rearward movement and automatically disconnects itself from further affecting the attained result of restoring the keys and key arms with the clearing yoke 34 still mildly engaging the same under the impulse only of its own weak actuating spring 51. This is another way of stating that the draw bar 38 through its wrist pin connection 31 with the clearing yoke 3334 disconnects from the latter when the same has restored the key and type arms to normal neutral or zero positions.

To positively disengage pin 36 from shoulder M of draw bar 38 at the conclusion of the effective movement of the latter on the return of the operating crank so that clearing yoke 34 will come to rest against the type setting arms 28 of the keys 2'! in their neutral or zero position, there is also mounted on plate 35 carrying pin 36 a dog 42 in the form of an adjustable slotted plate secured by a screw 43 to a flange 44 bent laterally from the said plate, by means of which screw and slotted connection the dog 42 may be advanced radially from the axis of operating shaft 22. Surface 46 beforementioned on draw bar 38 lies in the path of this dog. The dogs projection, so regulated by screw 43, causes it to engage surface 40 and causes pin 36 on plate 35 to slip out of engagement with shoulder 4| on the draw bar at the proper point. The idea is that this adjustment shall be so made that pin 36 will keep positive contact with shoulder after the printing operation.

4| on the draw bar until the latter has returned setting levers 28 to just the right point and thereupon totally relieve draw bar 38 from pin 36 so that the latter may ride under shoulder 4| and across an under surface 45 on the rear extremity of the draw bar. In other words, when the operating lever 20, on such an adjustment, moves forwardly to an extreme position, it merely accomplishes the printing operation. When it moves rearwardly, it picks up its actuator 38 otherwise idle and accomplishes the result stated.

It is sometimes desired to repeatedly print a number of checks of the same denomination, as, for instance, in a simple illustration, where a number of employees are being given a pay check of the same amount, say, $25. In that case, it is obvious that the operator should not be required to reset the amount keys 2'! back to $25 after printing each check but should be allowed repeated actuation of the main operating lever to produce on successive checks replications of the same amount as may be required To take care of this, I provide a simple means ,for rendering the resetting yoke 34 inoperative at the will of the operator by temporarily holding draw bar 38 out of all contact with the operating mechanism on the return of operating lever 20 This consists, in the present instance, of a dog 46 (Figs. 5 and 6) mounted to turn in a wall of the upper casing 4 on the right side of the machine adjacent the operating lever 20. Externally, it is provided with a finger piece 41 (Fig. 2) by means of which it may be adjusted by the operator between the positions of Figs. 2 and 5 and that of. Fig. 6. On the interior, it has a laterally and inwardly turned flange 48 adapted to engage beneath the draw bar 40, heretofore deing are to occur, finger piece 47 is rocked rearwardly to the position of Fig. 6.

Thereupon when draw bar 40 moves under the influence of the operating lever in either direction, it is held raised against the tension of its Spring 39 by the flange 48 of the do and is rendered idle and ineffective so that the pin 36 on member 35 of the operating shaft 22 cannot reach the shoulder 4| and cause the draw bar to actuate the clearing yoke.

The rubber vacuum cup 66 shown attached to the base element 3 and floor plate 6| thereof in Figs. 9 and 10 are for the purpose of insuring such contact with a table or desk that the manipulations of the operating crank 20 will not disturb the position of the machine.

In a check writing machine provided with a clearing yoke constructed in accordance with my invention, the following points are to be noted: the clearing or resetting yoke at all times hugs the arms of the setting keys for the type segments; it is displaced or retarded by the keys as they are advanced or by the key that is advanced to the greatest degree and when such clearing yoke is picked up by the actuating devices connected to the main operating means, it makes no noisy impact with the key or key arms but is positively actuated from that point in the same direction that its individual sprin 5'! is normally urging it.
