Abstract: 17,278. Dicker, S. G. S., [Gross, H. H.]. July 21. Money-delivering apparatus; coin and like handling appliances.-An apparatus adapted to throw out the sum required, or to give change from a dollar &c., comprises a keyboard having, in one form, thirty-three keys in three colours, namely nine unit keys 1 to 9, Fig. 2, in red, numbers 5 to 95 by fives in white, one silver dollar in white, and 10, 25, 50, and 100 cents in blue. The red key 5, the blue keys 10, 25, 50, and the white dollar key may be omitted. To give change from a dollar, the keys are marked with the complements to represent the sale, and to give change from less than a dollar, some of the ejectors are thrown out by a locking release bar provided with cams. Any sum required can be obtained by the operation of one or two keys together. The keys 37, Fig. 4, are provided with plates 39 having code projections to select from a series of U-bars 23 pivoted on the same pivot 24 as the keys. The U-bars 23 are provided with extensions 24<1> having pivoted thereto at 25 ejectors 26, weighted at one end 29 and having the other end projecting through a slot 27 in the casing and a slot 28 in the detachable coin magazine 13, and adjusted in height by screws 30. The coins are stacked in the magazine so that, on operating the keys 37, one or more coins are ejected and fall into a detachable hopper 18, Fig. 3, the lower end of which is closed by a gate 21 having a finger-piece 22, which, when raised, raises the gate 21 and allows the coins to drop into the hand. Pivoted on the pivot 25 is a lock-arm 33 weighted at one end 34, the other end passing through the slots 27, 28 and extending upwardly into the coin tube when this is empty, and being pressed down by the weight of the coins when the tube is full. The lock - arm is provided with a shoulder 35 adapted to engage a shoulder on the casing when the arm is in its upper position, i.e. when the coin tube is empty, so that the corresponding key cannot be operated. A locking release bar 42 is provided, which can be turned by a handle so as to engage humps 41' on the locking-arms 33 to release the locking- mechanism. The bar 42 may be provided with cams to throw some of the ejectors out of action when it is desired to give change for less than a dollar. The U-bars have stops 40, 72 engaging fixed parts 41, 73. An interlocking device to ensure the complete stroke of a key, and to prevent another key from being operated accidentally during operation of one or more keys, comprises two pairs of members 46, 49, Figs. 4, 7, and 9, depending from a shaft 45 and having ratchet teeth 46<a>, 49<a>, respectively pointing in opposite directions. The member 49 has a slot 50 engaged by a pin 51 on an arm 52 secured to a pivoted U-bar 53 adapted to be engaged by an extension 39<a> on the plates 39 when a key is depressed, so that the arm 52 is raised, the members 46, 49 are drawn forward, and a pivoted pawl 55 weighted at 56 rides over the teeth 49<a> until the end of the upward stroke, whereupon a pin 60 on the piece 49 engages a pawl-thrower 61 to lock the pawl 55 out of engagement with the teeth 49<a>. When the key has returned to normal position, another pin on the piece 49 releases the pawl-thrower 61, and the pawl 55 engages the teeth 49<a>, which is the normal position. To ensure the downward stroke of the key, another weighted pawl 57 is normally held out of engagement with the teeth 46<a> by a pawl-thrower 65, and at the end of the upward stroke, a pin 64 on the piece 46 strikes the pawl-thrower 65, and the pawl 57 engages the teeth 46<a> during the downward stroke, and at the end of the stroke, another pin on the member 46 causes the pawl-thrower to engage the pawl and hold it out of engagement with the teeth 46<a>, which is the normal position. A bar 68 is carried by the members 46, 49, so that if another key is moved during the operation of one or more keys, the extension 39<a> engages the bar 68 and prevents its operation. A release member 69 provided with a handle is adapted to engage the pawls 55 to release them from engagement with the teeth 49<a>.
