Abstract: 18,562. National Cash Register Co., [National Cash Register Co.]. Aug. 10. Type-writers and like machines; printing-apparatus combined with receipt checking and recording apparatus.- Relates to apparatus of the character described in Specification No. 14,003, A.D. 1897. The key, indicating, and registering mechanisms are similar to those described in the prior Specification, but a plurality of registers is used (four are shown in the drawing A<11>, B<11>, C<11>, D<11>, Fig. 7), any one of which may be brought into gear with the actuating-mechanism according to the nature of the transaction,'Cash,' 'Credit,' &c. to be recorded. For this purpose the driving-wheel on the main actuating-shaft B of the apparatus has some of its teeth removed so that the handle can be turned through a third of a revolution before actuating the apparatus. On the shaft B slides a sleeve J<11>, Fig. 6, with several cams G", H<11>, I<11>, any one of which may be brought under the lever E<11> by pressing special keys marked with the character of the transaction. Then, during the first part of the revolution, the lever E<11> is swung through a greater or less angle, according to the cam in action, and its rack Z' turns a pinion Y' correspondingly. The pinion is geared with a shaft Q<1>, Fig. 7, carrying a rotary frame in which the four registers are mounted. The frame is thus turned to bring the first driving-pinion T' of the required register adjacent to the actuating-pinions K<1>. In the subsequent movement of the driving-shaft B a cam U<1> on a geared shaft H, acting on forked levers P' carrying the shaft Q<1>, rocks the frame to engage the pinions T', K<1> and 'take off' on the required register the amount to be recorded. The register frame is ultimately returned t o normal position by a spring and special cam-actuated safety and stopping devices, to ensure accuracy of movement, are described. 'Carrying' in the registers is effected by spirallyarranged cams A<4> on a geared shaft Z<3> after the pinions T<1>, K<1> have been disengaged but b e f o r e the register frame returns to normal position. Whenever one of the register wheels has turned through a complete revolution, a tooth on an attached disc strikes a latch V<3> on a lever R<3> carrying a pawl S<3> and releases a spring pin T<3> which is thus forced out laterally into the path of one of the cams A<4>. The cam in passing rocks the lever R<3> and pawl S<3> so as to add one on the next registering-wheel and then a bevelled part thrusts the pin T<3> back again. A device, consisting of a sliding key with spring clutch and turn-button, is carried by a bracket so as to be in line with the shaft of the uppermost register ; when slid to one side it engages the end of the shaft and on turning the button the shaft is given a complete turn and carries all the wheels to zero. Means are also described for preventing the zeroizing action if any of the pins T<3> are not pressed back, and also for bringing each register in turn into position opposite the zeroizing device. The printing and slip-issuing mechanism are substantially similar to those described in the prior Specification. The ticket or slip is, however, printed with an advertisement on the back ; a separate type-wheel geared to the register frame is provided for printing the character of the transaction, and a clutch mechanism for throwing the check-strip feed-rollers out of action when desired acts also on the connection of the two printing-platens so as to disengage the upper one and render it inoperative. The electrotype roller for printing permanent matter is so mounted on its spindle that it can be readily withdrawn and a different one substituted.
