Abstract: 15,532. Rinsche, F. C. July 9. Typewriters and like machines.-In key-set, leveroperated, printing adding-machines of the type described in Specification No. 13,316, A.D. 1900, a laterally-movable paper carriage is provided capable of two positions, one on the right for printing an identification number against an item, and the other upon the left for printing and adding the item ; two strokes of the operating-handle are given for a line, one for each position of the carriage, and after each the carriage moves from one position to the other, but in the identification position the totalizing-counter is thrown out of gear and the line-spacing parts are not operated. The total key is only unlocked when the carriage stands in the item position. The machine is one of the multiple bank type, in which the operated keys act as stops to determine the extent of the forward motion of the denomination rack-bars, which are released and spring-impelled upon operation of the handle ; registration upon the totalizing-counter takes place upon the return movement of the rackbars, provided the pivoted frame 86, Fig. 5, has been raised so as to put the racks and pinions into gear. The carriage frame A, Fig. 1, is hinged to a saddle a laterally movable on ball races through a distance determined by engagement of the carriage handle A<1> with the ends of a slot in the framework. Line spacing is effected by the arm 138, which is suitably oscillated by the operating-handle, and the collar b<1>, which it strikes to rock the pivoted bail b, is so placed that it is only struck by the arm when the carriage is in the item position. To determine the engagement of the counter-actuating racks, the rear bar A<11> of the carriage has a cam-edge with which a roller upon the link E engages, and the link-work F, G is thereby positioned so that the link 93, which is oscillated from the handle-driven shaft 78 by the pins 90, 91 and means shown, may either engage the pin 88<a>, Fig, 5, in its slot 93<b>, or miss it, the arm 88 being correspondingly swung forward to raise the rack-engaging frame 86 or leave it depressed as shown. The lateral shift of the carriage at each operation of the handle is derived from the shaft 78 through the lever 81, the pin H, Fig. 9, upon which co-operates with the two hooked arms K, K<1>, which are spring-pivoted to the lever J and have guard wings L, L<1> so controlled that they can only be displaced to allow the pin to engage with a hook when the lever 81 is moving upwards. The lever J is thus rocked in opposite directions at successive movements of the handle, and transmits motion by a bell-crank lever to the carriage. The total key 148 allows the rackbars to take up positions equivalent to those of the numeral wheels, and its operation while the carriage is in the identification position is prevented by the mechanism shown in Fig. 4 ; depression of the key tends to raise' the opposite end of a lever 168 so that a r-shaped slot rises, and the pin 169 upon the rack-raising arm 88 by engaging in the vertical member of the slot causes the arm to be rocked and the racks put into gear with the totalizer. This action is however impossible unless the carriagecontrolled link 93 is in the depressed position, corresponding with the item setting of the carriage when the roller 93<a> depresses the arm y of a pivoted stop Y so as to leave the vertical member of the slot open. The total key shifts the inking-ribbon so as to print the total in a distinctive colour.
