With these and incidental objects in view, the invention includes certain novel features of con struction and combinations of parts, the essen tial elements of which are set forth in appended 46 claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part and it is to these im 25 provements that the present invention is directed.

The usual traveling carriage, a portion of which is shown in Fig. 3, carries a platen roll 40 (Fig. 1) (disclosed in the parent application) is operated, disclosed in the parent case, oscillates the shaft 53 ?rst counter-clock wise and then clockwise to normal position. By referring to Fig. 1, it is obvious that any movement of the shaft 53 is transmitted by means of the arms 51 to the bail 56 of the leading Initial movement counter-clockwise of which, by means of the stud 5i and the slot 50, 15 platen mechanism, see the co-pending applica tion of Raymond A. Christian, Serial No. 653,838, ?led January 27, 1933. Machine keyboard and operating mechanism 20 causes the amount rack 41 to move rearwardly until one of the graduated steps 46 engages the stud 43 of the depressed amount key 4|. This prevents further rearward movement of the segment 52; conse quently the bail 5B completes its rearward move‘ The machine of this invention has a plurality of denominational rows of amount keys 4!, one of such denominational rows being illustrated in The amount keys 4| are depressibly mounted by means of a top keyboard plate 42 ,25 having therein slots adapted to loosely support the upper end of said amount keys and by means of studs 43 secured in the lower ends of said ment independently thereof, ?exing the spring 54. In its return movement clockwise, the bail 56 20 picks up the segment 52 and returns said seg ment and the amount rack 41 to their normal, or zero, positions. In case no amount key is de pressed, the‘ zero stop lever retains the rack 41 in its zero position, as shown in Fig. 1, during ma chine operations. 30 the proper denominational wheel of the selected totalizer positions the rack 41 commensurate 30 with the amount on said totalizer wheel in a manner presently to be described. 35 Totalizers Depression of one of the amount keys 4! moves the stud 43 carried thereby into the path of one In its present embodiment the machine of this invention is equipped with two totalizers, of a series of graduated steps 46 on an amount 40 an upper add-subtract or No. I totalizer and 8. rack 41 mounted for horizontal reciprocating lower adding or No. 2 totalizer (Fig. 1) ; however, 40 present machine with additional totalizers.

Located on the right hand side of the key board is the usual starting bar 64 having stems 65 and 66, which are pivoted respectively to a amount keys 4!, as explained above, an alining bar 84 connected by a pair of arms 85 to a shaft 86 is rocked into engagement with teeth 81 of the segment 52 to plate 61 pivoted on a stud 68 secured in the frame 3!, and an extension 69 of a lever 10 loose on a stud 1i also carried by the frame 3|. The plate 61 carries a stud 12 which cooperates with the 60 of the depressed amount key. In subtracting operations, the corresponding wheel of the No. l or balance totalizer is rocked United States 65 No. 1,601,102 issued to F. W. Bernau on Septem Depressing the starting‘ bar 64 rocks the plate 61 clockwise against the tension of a spring 16. ‘ the stem 66 of rack 41 revolves the wheel 80 of the No. I or balance totalizer in a reverse or counter-clockwise direction until said rack 41 is stopped by the de pressed amount key, as explained earlier herein. After the leading frame bail 56 and the rack 41 complete their initial. movement rearwardly, the wheel of the balance totalizer is disengaged from said rack 41. This results in the value of the depressed amount key being subtracted from the balance totalizer. The wheels 80 (Fig. 1) of the No. l totalizer 75 2,184,688 each carries a tripping plate 88 with diametrically opposed tripping teeth which cooperate with add transfer pawls 89 and subtract transfer pawls 90 to transfer amounts from lower to high5 er denominations and to position the racks l1 in total taking operations in a manner tions,presently the add to be described. In adding opera transfer pawls 89 are rocked into the path of 3 I09 which actuates the printing segment 95 and the arm 96 in a manner presently to be described. In‘ adding, subtracting, and total taking opera tions, initial movement rearwardly of the seg ment 52 (Fig. and theframe amount 41 means under 5 influence of the1)leading ballrack 56, by of the link 94, positions the-printing segment 95 commensurate with the position of the amount . the teeth of the tripping plates 88, and the sub- 10 tract pawls 90 are simultaneously rocked out of the path of the teeth of said tripping plates. In subtracting operations, the subtract transfer pawls 90 are moved into the path of the teeth 0f the tripping plate 88 and the add transfer pawls rack 41. When the bail 56 reaches the terminus of its rearward movement, it dwells brie?y in this 10 position, and, during this dwell, clockwise move ment of the shaft 91 and the yoke I08-rocks the release trigger I00 counter-clockwise to release the arm‘96 and the printing segment 95 to the 15 89 are moved out of the path of said teeth, Referring to Fig. 1, which, as previously stated, action of the spring I09, which has been given 15 added tension by clockwise movement of the bail shows the mechanism for one denominational unit, in adding operations, when either of the teeth of the tripping plate as wipes past the trip20 ping point of the adding transfer pawl 39, the -’[,ran5fer mechanism for the next higher denomination is tripped, thus causing one to be added in said next higher denomination.

Directing attention to Fig. 2, a row of control keys H8 and a No. I add key II9 located on the left hand side of the keyboard control the func tions of the totalizers.
