ofanotch at one corner, that is engaged by. I

pin 28 on a lever 29 pivoted to the`side plate,

20. This lever 29 is caused to oscillate by reason of the back.and forth movement of .the said actuating member... In the form 30 1s reciprof,

to a. main rock e' a shaft 34exten hng across the machine. A

pin on the pitrnan 30 rides in the'slotted,

end 36 of the lever 2 9 and the lever is oscil lated by the reciprocation of the pitman. It will be understood that the restoring bar 22 can oscillate in .the gui'ding slots 25 :and 2G to permit swinging of the arms 23 andv 24. A coil spring 'connectsthe arm 23 Witha suitablyr located pin 3S that willy draw the arm 23 downward as well as rearward, and the arm is normally held in "engagef'nent with the pin 28 on the lever 29, pawl 39 is pivoted on the side plate 20ratii$ rear, and its 4free forward end is moved iliivvard against the arm 23, by reason 4of the pin 3S being locatedon this pawl. In the lower edge of the arm 23 is av shoulder 40'engaved by the pawl when the arm is moved ibrward from its normal posit-ion. On the opposite. side of the machine moet of these parts are duplicated as will b'e seen in Fig. 2. A Pitman 41 caused to reciprocate simultaneous with the ,lait-man 30, by means At the rear the plate 21.

not set forth herein. A lever 442 identical .with the lever 29 is provided that is oscil- 4is also fast to the restoring bar this arm will move simultaneous therewith. It will be noticed that therestoring bar 22.engages a. toothed lever 4 that forms part of a transfer mechanism.' 1t will be seen that this -in Fig. 3

lever when Vthe restoring bar moves to the other end of its slot as-indicated in Fig. 4, is swung to the position indicated in broken lines. And it will be uhderstood that if the toothed lever is controlled by a spring or other member it will be returned to former position .when free toy move, upon retraction of the restoring bar. lVlien the pitman 30 is moved forward to the position indicated l the lever 2 9will move-rearward 'to bring its pin 28- to engage the abutment 27 of the arm 23, and likewise the pin 43 will engage 'the abutment 44.on the opposite side on the frame 24;the yseveral springs connected-with these arms serving to move the, arms downwardly for such engagement. Upon return movement of the pitmen the arms will start to move forward and the restoring bar will advance in the slots 25 and 26. But thisv short movement of therestoring bar will take place at the initial portion of the return movement of the pitmen and levers. Just before the restoring bar reaches the end of these guide slots, ex V tensions nd- 51 on'the arms.23 and 24 respectively will strike stops 52 and 53 on the side plates, that willcause the restoring bar to rock on its axis to swing the rear ends of these arms upward and away from the pins 43 and 28 on the side levers. This will -permit the continued rearward movement of the two levers 29 and 42 -as the pins on the levers will move under the arms, as indicated in Fig. 4; But just 'previous to the release of the arms 23 and 24 from'the lever pins, the pa'wls 39 and 45 .will move to engage the abutments40 and 54 on the arms 23 and 24 respectively,-that will prevent at this stage retraction of the arms and restoring bar by the springs4 37. and 46, as. indicated in Fig. 4. The continued retraction of the pitmenv and levers 29 and 42w1l bring the pins 28 and` 43 thereon into engagement with lugs '55 and 56 on the pawls 39 .and 45 respec- This will tivel and'shiftthe pawls awayfrom the shou der s on these arms; see Figs. 1 and -2. rmit the retraction of the arms and restoring baz-by the springs 37 and 46.

gage a pin 49 on the arm 23. By this means the arm 23, also arm 24, are swung upward and held from engagement with .the pins on the levers 2S) and 42, when the latter are swung by the two pitmen. In the arrangement shown this lever 57 also performs auf other function. On the side plate 20 is pivoted a lever 58 whose upper end connects by stud 69 with a suitable frame 1() carrying the numeral pinions 5, by which lever the tuinions are moved to and from the rack bars 6, and to and from the toothed levers. 4. The lever 57 is shown as pivoted on the lever 58, and the forward end of the lever 57 carries a pin 60 arranged to engage abutments 61 and 62 formed'by a slot in the' pitman 30. At the latter part of the fop ward'movement ofthe pitman 30 this pin will strike the abutment 61 and the lever 57 will swing the lever 58 to shift the pinions.

At the latter part of the return of'the pitman 30 abutment 62 will strike the pin 60 and.again shift the lever .58 to return the pinions to.former position. The rear endy 59 of the lever 57 is normally free from-the pin 4S), and does not interfere with the engagement of the arm 23 with the pin 28' on the lever 29. The special keys 1, 2 and 3 engage and depress a swin 'ng lever 63, and the latter carries a bent ever 64 whose `extremity is adjacent a pin 65' on the lever 57. By this means when either of these keysis de ressed the lever 57 is rocked and engages t e pinl.49 on arm 23 to shift the -arms away from. engagement with the pins the levers 29 and 42. -But when a fourth key 66 is depressedthe lever 64 is rockedaway frm the pin 65, and the means formoving the restoring bar is not thereby dis'- abled. This key is the non-print key of the machine, and it is desired to have the' adding mechanism operate as usual, lWhenI 120 such key is depressed.

In order to hold the lever 58 and the frame in the two positions of engagement'v of the numeral inions, I provide s. locking= member in the orm of a leverv 85-havinga tooth 8 6 on its extremity that is pressed upward by 'a spring: 87 to alternately engage notches 88 Aand 89 in the lower end of the lever 58. It will be seen that this tooth 86y has parallel sides with an langular extremity.

The notches 88 au'd S9 are substan- 130 tilly angular, but have at the ont-rr portier 'of each a. straight or vertical wall extend# ing perpendicular to the end of lever 5S,
