Abstract: 277,845. Brandt, E. J. Dec. 29, 1926 Money-delivery apparatus comprises a bank of coin tubes provided with coin ejectors, and control keys adapted to eject, according to the setting of the key-board, either the amount indicated upon the key depressed, or the difference between this amount and a. dollar or other money value which is taken as a basis. Means are aso provided for giving change from tender of less than a dollar. Further keys are adapted, when struck, to deliver at least two coins of the same denomination, a coin on the down stroke, and one on the spring-controlled upstroke. Fig. 1 shows the slidable key-board 1 carrying keys 2 numbered from 1 to 99. Keys 3 are adapted to discharge small change for a quarter, fifty cents. or a dollar, respectively. A key 4, marked D20, is adapted to release two dimes, and a, key 5, five pennies. Keys 7, positioned in a cut-out portion 6 of the keyboard, are adapted to discharge coins both on the up and down strokes, the key marked P10, for example, discharging five pennies on each stroke. To slide the keyboard 1 for a single operation to pay the amount indicated upon a key depressed when the board is set for change-giving or viceversa, an automatic return shift key 8 may be rocked either forwardly or rearwardly, the keyboard being automatically reset in its original position when the transaction is completed. To return change from a, fifty cent piece, from seventy-five cents, or from twenty-five cents. elongated keys 9, 10 are provided to withhold the corresponding amounts the change when a main key 2 is depressed. The coins are carried in tubes 13 - - 20. Fig. 2 shows the mechanism connecting the keys 2 with the coin ejectors. Fingers 25 on ,a foot 24 on the shank of each key 2 are positioned over nested rock-arms 26 which are linked to levers 29. A coin ejector 30 is pivoted to each lever 29 and projects into a coin tube. When a key 2 is depressed ,the fingers 25 engage certain of the rock-arms 26 to actuate the appropriate ejectors 30. To prevent operation of the machine when the coin supply is nearly exhausted, levers 38, mounted in slots in the lower parts of the coin tubes, are formed with flat faces normally contacting with the coins. In the operative position shown in Fig. 2. the levers 38 swing forwardly, allowing a, spring- controlled latch 43 to engage a notch 44 in the lever 25 to lock it. The keyboard 1 is moved to a different setting by a main shift lever 45 which is linked to a slide 49. The slide 49 is carried in a guide 50, Fig. 9, and is provided with spring- controlled plungers 55, 56 which contact with lugs on the key-board. The key 8 is formed with. a plunger 62 adapted to rock on a pin 64. A pin 65 on the plunger 62 is normally retained in contact with a plunger 66 carried on the machine base. A central arm 74, Fig. 7, on the plunger 66, carries a trip bar 75 extending beneath the rock-arms 26, Fig. 3, so that when any of the arms 26 are depressed, the bar 75 is also depressed. The key 8 is rocked so that the pin 65 moves through an arcuate slot 76 in the plunger 66 to the position shown in 'dotted lines in Fig 8, moving the key-board to the new setting. The depression of a key 2, to carry out the transaction, depresses the trip-bar 75, allowing the 65 to contact with an intermediate portion 77 of the plunger 66, Fig. 8. and when the key 2 is released, the bars 26 and the tripbars 75 rise, the pin 65 riding to its normal position through the arcuate slot 76, thus repositioning the key-board in its original position. The keys 9, 10 are formed with slides 79, 79<1> having apertures 81, 82, 81<1>, 82<1>, res. pectively, to receive locking cams 83 on a latch 84. The lower ends of the slides 79, 79<1> engage levers 87, Fig. 3. When a key 9 is depressed and locked temporarily, the depression of a key 10 will release the key 9, the cam 83 being forced out of the notch 81. The rear ends of the levers 87 are linked to pivoted levers 90 formed with fingers 92 adapted to depress, and render inoperative, the corresponding ejectors 30. The key 9 is adapted to depress the ejector for fifty cent pieces, the key 10 depressing the ejectors for fifty cent and twenty-five cent pieces. The keys 9, 10 are released by the trip-bar 75, Fig. 3, depressed to contact, with the latch 84 and withdraw the cams 83, by the operation of any bar 26. To render individual levers 38 inoperative, slides 93 have ends 94 which may be positioned in the path of the levers 38 to lock them. All the levers 38 may be simultaneously locked by the actuation of a rod 95 connected to a pivoted bar 96<1> .extending beneath all the latches 43. To obviate tilting of the key-board 1 when it is manipulated from the main shift key 45, a rock shaft extends transversely of the machine, Fig. 3, and carries short notched levers 99 which receive pins 100 on the key-board. The keys 9, 10 are locked out of action, when the key-board 1 is set for the discharge of the amount indicated on the keys, by pins on the slides 79, 79<1> which, in this position of the key-board, engage the edge of the plate, fixed under the key-board. The keys 7 are slidably positioned in a channel 103 of a frame 102, Fig. 13, and rack teeth 111 on each key shank engage a pinion 112 carried by a shaft 113. Each pinion is mounted on an independent shaft. The shaft 113 carries cams which are rocked by the depression of the key and are again rocked by a spring 106 on the return stroke, thus acting twice on the cam followers which are the rock arms 26 positioned below the cams. The coins discharged enter a main shoot 129 pivotally carried on pins 130, whence they normally pass along the base plate of the machine to a forward opening. The coins may, however, be discharged rearwardly by rocking the shoot 129 to the position shown in Fig. 3, when the coins pass to one of the shoots 135, 136, Fig. 5. A rigid deflector 137 is mounted at the junction of the shoots 135, 136.
