When however the actuating lever is ment lever in acontrary direction so as to project the rear pawl into the matrix path and retract the front pawl.

The actuating levers 13 of the several escapement mechanisms are controlled in their action by a series of substantially L:

shaped operating levers 19, which are pivotally mounted at their lower ends on a horizontal axis with their upper ends arranged in position to engage the arms 16 of the actuating levers of the selected magazine. These operating levers 19 are normally disengaged from the lever arms 16 but, are adapted, by the operation of the keyboard mechanism, to be rocked upwardly and rearwardly to engage said arms and rock the lever arms 15 downwardly away from the 'escapement levers so as thus to allow the springs 12 to function.

The operating levers lilare rocked upwardly in the'foregoing manner by means ofthe 'usual vertically reciprocating reeds 21, whose upper ends as shown, are in posiyokes upwardly and causes a correspond.

ing movement of the operating levers 19, all as well understood in the art.

The operation of the parts above described is as follows:

i On the. depression of a finger key, its

corresponding cam yoke 22 is tripped. and by the rotation of the cam 23 the associated reed 21 is elevated torock the corresponding operating lever 1 9 upwardly and rearwardly, whereby the engaged actuating lever '13 is rocked to the position shown in Fig. 1. In this action, the front spring 17 is depressed and the arm 15 of the actuating lever 13 disengaged from the escapement lever 7, so that the rear spring 12is allowed to reverse the position of the escapement lever, thereby retracting the front *pawl- 10 to release the foremost matrix and at the same time projecting'the rear pawl 11 into'the path'of the next matrix to arrest it momentarily. This action is followed al most instantly by the return of the parts to theirformer condition, disengagement of the'operating lever 19 from the actuating lever 13 permitting the latter, under the influence of the springl'Z, to re-engage the escapement lever androck it back to itsoriginal position, thereby withdrawing the rear pawl 11' from the matrix path and lower magazine.

It is to be noted that the movements of the escapement levers are effected only un derthe influence of the two springs, so that in the event of any obstruction to the movement of the parts, as by theclogging of the matrices,'or their misplacement, or from other causes, no damage can result. The arrangement is also useful in taking up the overthrow motion of the keyboard devices and in relieving excessive wear upon the rubber rolls. These and other advantages will be readily appreciated by those skilled in the art. I

-In Figs. 4, the construction of the escapement mechanism is substantially the same as that above described, but in this case the actuating levers 13 for the escapement levers are directly controlled in their operation by the keyboard reeds 21 which for this purpose are extended upwardly at an inclination, as at 26, so that their upper ends will be in position to engage the'actuating levers. The two arms 15f and 16 of each lever 13 are disposed in line with each other, the forward arm-16 being arranged in position to be engaged and rocked upwardly by the keyboard reed to the position shown on the upper active magazine, and thereby move -'the"rear arm 15? downwardly out of engagement with the escapement lever in order toallow the spring 12 to actuate the escapement lever. Since the reeds 21 engage the undersides of the actuating levers 13 and operate the same by an upward vertical movement, the upper ends of the reeds are disposed inwardly of the planeof the forward ends of thelnaga zines, and hence it is necessary, before the magazines can be shifted, to move the upper ends of thereeds out of the path of the magazines. This is accomplished, in the present instance, by providing a comb plate 26 through which the reeds extend at their upper ends, which plate is carried by arms 27'pivoted on a horizontal axis 28, so that by rocking the arms the comb plate will shift the upper ends of the reeds into or out of operative relation to the'aetuating levers. The comb plate may be operated by any suitable means, such for exam is as a handle 28 'fixed to one of the arms 2 and extending within convenient reach of the operator.

The foregoing improvements have been shown only in preferred form and by way of example, and obviously many changes and modifications may be made I therein without departing from the spirit of the invention. It should be understood, therefore, that the invention isnot limited to any specific form or embodiment except in so far as such limitations are set forth in the appended claims.
