The arm 23 is returned into the operative position shown in Figures 2 and 3 by the resetting cam 25 which lifts the spindle 24 axially against the action of the spring 248 ancl'when the lower end of the spindle is resting on the highest point of the cam, the pin 25 v on the cam 25 ,strikes against the pin 24" on the spindle 24 and turns the spindle and thereby the arm 23 through QO in a horizontal planeagainst the action of the spring 24 Thespindle 35 actuated by the pinion 34, is provided with a boss 52 furnishedwith a radially disposed part 53 provided with a cam surface 53 arranged to act on a rocker element 54 (drawn to an. enlarged scale in Figures 5 to 8) secured on theswitch-over spindle 49, said rocker element 54' being provided with two cam faced members 55, 56, the action of the part 53 being to efiect a partial rotative movement of the switch-over spindle 49, the direction of rotation being dependent on the longitudinal position of the switch-over spindle 49, which latter is furnished with means, comprising a pin 51 coacting with a stop element 59 mou'nted on the casing, for limiting the degree of rotative'movement in both directions. 1 The switch-over spindle 49 constitutes the operative member for'the pre-setting drums 59, 69 and 8! which'are mounted on a spindle 6.2 supported in bearings 63 secured in the casing 2. The pre-setting drums 59, 60, 6| comprise three figure drums, the units drum 59 is actuated in either direction by a double action ratchet mechanism hereafter described operated by the movements of the switch-over spindle 49, and is interconnected with the tens drum in the known manner, and, the hundreds drum SI is interconnected with the tens drum, by means for driving pinions 64, 65 respectively, said pinions being mounted in(' separate carriers 56 and 61, furnished with springs, such as 65 and 97 to maintain said pinions in mesh with toothed wheels 68, 69 on the figure drums 99 and BI respectively.
The units drum 59 is actuated in either direction from the spindle 49 through double acting mechanism comprising a pair of ratchet wheels I0, I! formed on a drum I2 actuated by a ratchet arm I3 pivotally mounted at I4 on the outer end of an arm I5 secured on the spindle 49 (Figure 9). The arm I3 is provided with pawls I6 andIl arranged to coact with the ratchet wheels 19 and'Il respectively by means of a vertically disposed element Illslidably mounted on a pair of pins I9 secured in a U-shaped member 89 fixed to the casing 2.

V
For the purpose of effecting the reversal of the direction of rotation of the figure drums 59, 69 and El and setting drums 89, 99 and 9! a switch-over mechanism is provided and to this end each of the figure drums 59, B9 and El is furnished with a radial projection 94 so arranged that when said drums come into the zero position the projections 94 make contact with projections 95 provided on electrical contacts 96 coacting with contacts 91 (more clearly illustrated in Figure 10 which diagrammatically illustrates the electrical connections) and when these coacting contacts are closed a current is completed through the battery 98 and an electro-magnet 99 which efieots the axial movement of the pro-setting spindle 49, one end of which constitutes the solenoid element of the electro-magnet. Each of the setting drums 89, 9.9 and 9! is likewise provided with means such as a cam shaped projection lllll'adapted when said setting drums'are in the zero position to close a second series of contacts I94, 1'02 through intermediate rollers I93 formed of insulating material and thereby completes a circuit through a second electro-magnet I04 to effect the axial movement of the switch-over spindle 49 in the reverse direction. 4
In operation, the figure drums 59, 50 and GI are first set to zero position and the setting drums 89, and 91 to the figure at which it is desired to insert a strip, the electro-magnet 99 in circuit with the contacts 99 operates the switch-over spindle 49 in one direction, the printing machine is set in motion and'when the predetermined enu-mb'er ofesheetslhave beerrprintedthe' swinging zontally through 90 delivers the severed strip on 1 {top of the 'pile of paper situated-adjacent the side -wall X (Figure 1), of the: casing l.
the, number given on the figure drums/will be that At this -stage originally shown on the setting drums while the latter will have come to zero. As the arm 23 passes into the position shown in broken lines in Figure 1, the pin 4!] is forced upwardly by the lever 31 under the action of spring 39 thereby reengaging clutch 21 through shaft I5 Shaft l5 now rotates cam 25, lifts spindle 24 and the pin 25 simultaneously strikes the pin 24 and thus efiects the resetting of the arm 23 and at the same time a further length of paper-strips is fed into position and will be severed automatically from the main strip as the arm 23 again drops into its operative position. As the press continues to deposit the sheets on the pile the figure drums will be returning to zero and the setting drums will return to their original set position, and so on as the printing machine continues to operate.
