Abstract: 151,319. Norton, S. H., and Day, S. H. June 6, 1919. Money-delivering apparatus.-Change for definite amounts is contained in series of drawers 5, each drawer being operated to deliver the change by a separate key 32. The operation of each key preferably closes an electric circuit, including an audible signal such as a buzzer b, and means are preferably provided whereby each operated key remain locked in the operated position until released by a master key. Means are also preferably provided to give a visible indication after the entire number of keys of any one set have been operated. Each drawer 5 comprises a front 10 secured to outer sides 7<1> and a back 7 which has a projection 17 below the bottom of the drawer. The bottom 8 is mounted on a hinge 9 so that when the drawer is opened the change drops into the hand of the operator. Each drawer is urged towards its open position by a spring 18, and is retained in the closed position by a pivoted catch 20 which engages the projection 17 on the drawer. The catch 20 is disengaged from the projection when the corresponding key 32 is depressed. The key lever 27 is normally held in its raised position by a spring 27<1>. The key levers are connected electrically, for-example, as shown in Fig. 6, in circuit with a buzzer b. When a key is depressed, the key lever 27 contacts with a spring-supported bar 46 and completes the circuit, causing the buzzer to sound. When the key is released, the lever rises sufficiently to break the buzzer circuit. The key is, however, prevented from rising into its normal position by a stop 39, which is pressed forwards by a spring 41 to engage a notch 37 on the key lever, a projection 42 connected with the stop 39, at the same time moving forward into a slot in a bar 72. The bar 72 is provided with a milled head outside the casing of the apparatus, so that, when desired, the bar may be rotated to press back the projection 42 and therewith the stop 39 so as to allow the keys to rise into their normal positions. Each set or row of keys is provided with a pivoted indicator 54 which is normally held out of sight by the pivoted armature 56 of a.n electro-magnet 48. When the electro-magnet is energized, the armature 56 is drawn forwards and allows the indicator 54 to fall so that it can be seen through a window at the upper part of the casing. The indicator is returned, when desired, to its normal position by a rotary arm 65 which bears against a projecting finger 61 on the indicator. The keys of any set or row are electrically connected in series with the electro-magnet of the corresponding indicator, so that the latter is operated only when the whole of the keys in the set have been depressed. For this purpose, at each key is provided a pair of spring contacts 44, 45, Figs. 6 and 8. A push pin 43 on the bracket 40 which carries stop 39 and projection 42 projects through one of the contacts 44 and abuts against the other contact 45, thus holding the two apart. When a key is depressed and the bracket 40 is pressed forward, the pin 43 moves away from the contact 45 and allows it to spring against the contact 44, thus completing that part of the indicator circuit. In a modification, the rotary slotted bar 72 for restoring the depressed keys to their normal position is replaced by a sliding bar which is formed in two parts. These parts when pushed from the back towards the front of the apparatus to re-set the keys, bear against the projections 42 and push the brackets 40 back into their original positions against the action of the springs 41.
