Abstract: 315,753. P÷schl, O., and Benesi, M. July 17, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cash registers; audibde indicators. - The indications of registering apparatus are reproduced audibly by combining with the apparatus one or more phonographic devices adapted to be set and operated in accordance with the setting or indications of the apparatus. As shown applied to a cash register, Fig. 1, the keyboard A is associated with means for adjusting one or more sound record carriers B, the carriers being released to operate reproducing devices C by means associated with the operating mechanism E of the cash register. The keyboard consists of several banks of amount keys 2 arranged in the usual manner in the frame 1 and each co-operating with a plate 5, Figs. 2 and 3, on a bent rod 6 guided in the frame 1 and a plate 7. Each of the rods presses against a plate 10 fixed to the front end of a rod 11 guided in the plate 7 and in a rear plate 9, Fig. 7, the rod terminating in a head 12 engaging a plate 14 on the end of a rod 15. The rods 15 carry cross bars 17 controlled b springs 18 and guided in slots in a pillar 20. These bars operate to release and position the sound record carrier B constituted bv a drum mounted to slide along and rotate on a shaft 21 and carrying on its periphery sound records in the form of lines x arranged at fixed distances from each other. When one of the amount keys is depressed the corresponding rod 11 is displaced to force its bar 17 rearwards so that its left hand end, Fig. 4, works along the inclined edge of one of the teeth of a comb plate 26, thereby raising the plate to release the projection 23 thereon, from engagement with the projection 22 on the carrier B. At the same time the other end of the operated bar 17 acts upon a wedge-shaped tooth 30 on the upper end of a vertical bar 31, Fig. 8, and forces it downward against the action of a spring 34 so as to project the lower end 36 of the bar 31 into the path of movement of the carrier B and arrest its movement, the extent of such movement depending on the key depressed. The shaft 21 is carried in a frame 50 and has secured thereto a ratchet wheel 51 engaged by a pawl 52 and a spiral spring 53. The spring is attached at its outer end to one of a set of four pins 54 on a disc 55 having a single cam tooth 56, Fig. 13, and connected to a gear wheel 58 meshing with a pinion 59 on a governor shaft 60 with a conical sleeve 63 controlling a brake brush 64. The wheel 58 is provided with bolts extending into the carrier B to effects. its rotary movement. This movement is under the control of the indicator mechanism F of the cash register. The shaft 74, Fig. 11, rotated by connection with the main operating shaft E, Fig. 1, rocks the indicator releasing lever 72 and through an extension 77 and stop pin 78 on a gear wheel 79 rotates a pinion 70 on the shaft 21 to effect the winding up of the spring 53. A spring 82 serves to return the wheel 79 on the return swing of the extension 77. The carrier B is released for rotation by withdrawing the spring-controlled pawl 85, Fig. 13, from engagement with the cam tooth 56 by the co-operation of a bolt 89 thereon with a spring- controlled tappet 90 pivotally mounted on a rod 91 one end of which is operatively connected to a lever 93 such as the key-locking lever of the cash register. The reproducing device comprises a sound box 97 containing a diaphragm and jewel 98, a conducting tube 99, flexible tube 100 (Fig. 1) and sound horn 101. The tube 99 is pivotally mounted on an arm 103 and is pressed downwardly by a spring 105; the jewel is however normally prevented from bearing on the sound record surface by a rod 107 slidably mounted on the arm 103. The rod is connected at its end to the rod 91 the movement of which releases the sound box and permits the jewel to bear on the record surface. The re-setting of the carrier B is effected by the crank handle operation. A pin 41 on the handle 40, Fig. 9, rocks a two-armed lever 42 and through a push rod 44 rocks a bellcrank lever 45 to displace a spring-controlled shaft 46. The shaft 46 is provided with stops 47 projecting into the path of the carriers B and restores them to their original positions, the projections 22 re-engaging the projections 23 on the comb plates 26.
