Abstract: 21,095. Laurick, C. Oct. 21. Receipts, checking and recording.-A set of numbering type-wheels on concentric shafts and two sets of legible wheels geared to the shafts are turned to exhibit, print, and add an amount by the separate operation of spur-toothed racks in gear with intermediate pinions 14 on concentric shafts 13, and the remaining operations are effected as follows by working a hand-lever 30 to and fro from the position shown :-The rack, and consequently the indicating and printing wheels, are returned to the zero position by a pair of carriages 27 sliding on guides 29 and drawing along them a cross-bar 37, Fig. 15. Being on trunnions, the cross-bar tilts away from the ends of the racks when it reaches the dip 31 in the guides, and in the return movement, owing to its lower edge catching the bight, it is turned at right-angles so as to be clear of the racks, which are operated between the two movements. On the carriage regaining its initial position, the cross-bar rights itself. The racks having wave teeth on their undersides were locked in their registering positions because a rocking frame 60 with justifying spring studs 63 is held close up by a pivoted strut 54, and therefore at the beginning of the restoring action the struts are tripped because they are dragged by latches 56 connecting them to a branch 49 of the main lever. On reaching the rocking frame, the main lever applies the justifying. studs lightly so as to allow the racks to be set for another number, but in the return movement it displaces a hanging lever 69, Fig. 12, and this in turn by a hook 65 on a pivot 68 fits the rocking frame again under the strut which lies loose upon it because the latch has been tripped by a fixed stop 57. The adding-wheels on a shaft 158 in a rocking frame, having been put into gear by one of the racks, are brought out of gear in the return movement of the hand-lever, (that is, after the racks have been restored to the zero position), and the tens are carried by arms 180 with pawls 181 on a second shaft 159 in the rocking frame, sliding bridges 160 between the shafts being set by dog teeth 161, 188 on the adding wheels so that the pawls must ride over cam lugs 183. A circular arrangement of the pawl-bearing arms permits each adding - wheel, if necessary, to shift its bridge before the next pawl to be operated has passed across it. A sector 95 turning with the handlever lifts a latch 89 from the cash drawer 288 to a hook 100, and the carriage, after returning, holds up another latch 92 so that the drawer is free to be opened but when closed again trips the hook from the first latch. A pawl 105 travelling over a fixed rack 107 till it strikes a pin 108 and lodges in a. book 111, ensures the complete return of the carriage. In addition to the numerical rack and wheels, there is also a rack to indicate and print the operator's distinguishing mark or letter, and another rack and wheels to distinguish the kind of transaction. The carriage in its right-hand position applies interlocking mechanism to the three racks, which makes it necessary to operate them in order. The indicating-wheels are covered by a shutter while the racks are operated. The adding- mechanism is put into and out of gear by the mechanism shown in Fig. 32. The operator's rack 2 pushes aside a lever 175 which by means of a hook 192 drags after it a second lever 170 ; this lever in turn pulls the rocking frame 178 of the adding- mechanism till an arm 193 turning with the first lever 175 lodges in a hook 194 on the second lever 170. When the transaction does not require registration, the other special rack has to be pushed so far in as to make a pin 197 disengage the draghook 192, and so prevent any movement of the rocking frame by the operator's rack. The cash drawer has horizontal and vertical rollers running on rails. Before the hand-lever can be put back to the initial position, a detent must be released by closing the hinged lid of an aperture after the operator has inserted an identifying-check which eventually drops from a sliding shelf. In a simpler apparatus, Fig. 1, with no re-setting carriage and dependent mechanism, the numerical racks are normally locked by an angle-iron cross-bar 37 on trunnions, which is held by a detent key 39 under the distinguishing rack 2, and the latter is locked until a key 36 pivoted on it is disengaged from the cross-bar. The key 39 is re-set by the cash drawer 46.
