Abstract: 555,538. Money-delivering apparatus. HOPE, C. May 11, 1942, No. 4922/41. [Class 27] A change giving machine of the kind in which reading feelers co-act with a perforated or equivalently characteristically formed plate, drum or like selector set according to difference between an amount tendered and a purchase price, has a separate selector for each kind of coinage (e.g. silver, copper) and means operated by insertion of a coin or coins for setting it. Coin tubes 13, Fig. 3, one for each of the different coins of the kind (e.g. silver, copper) are carried on a fixed plate 21 and are slotted at the bottom to allow ejectors 29 pivoted on feelers 31, 33 sliding in a fixed transverse bar 34 to eject the coins into a shoot 24 and so into the hand of an operator when he pushes back the frame 26, 24, 25 against the action of springs 27, the frame sliding on fixed guides 35 to tension springs 37 and thrust the feelers 33 against the selector drum 50. The feelers that meet holes in the drum carry the ejectors 29 far enough back to allow the heavy end 39 to tilt the front 29 up to engage the lowest coin or coins in the tube, and eject them on return. A single and a double coin ejector may be fitted at the end of a tube, for example, those controlled by the double column of perforations 33a, Fig. 2, on the silver drum 50, or copper drum 51. A coin tendered is inserted in its appropriate tube 13 by thrusting it between a fixed roller 15, and a movable roller 16, mounted on a bail 100 swinging round a pivot 19 and rocking by a link 20, a lever 52, 53 on a shaft 54 and rack 55 a ratchet pinion 59 formed on the selector drum. The rack member 56 slides on guide pins 58 on the lever 53 to give a one-way drive to the drum which is held by a spring detent 121. The drum is also set to the purchase amount in a reverse direction by an opposite ratchet toothing 67 engaging one-way pivoted teeth 66 on a wheel 65, loose on the shaft 54 connected by a link 62 to a sliding setting member guided in a slot in the cover of the casing. The drums are thus set to the difference to cause delivery of the change. Should a coin tube be empty, a portion of the lower front wall is mounted as a tongue moving round a pivot 41 on the tube and has a counterweight rod 42 attached to cause the tongue to swing into the empty tube and drop its end 43 to engage a piece 44 on the frame 26, 24, 25 and hold it against use. The sales may be totalled by pinions 105 secured to the wheels 65 engaging totalizing counters 104. Transfer mechanism.-A transfer is necessary between the silver and copper drum, and the latter therefore has a cam 68, Fig. 2, to engage a fixed wheel 69 and shove the drum 51 along its shaft so as to bring a tooth 71 on it to engage an end rack 72 on the drum 50. Zero setting of the drums 50; 51 is necessary after each transaction and is effected by wheels 87 thereon engaging friction wheels 80 loose on shaft 54 and having ratchet pinions 81 engaged by pawls 82 on arms 84 fast to the shaft which can be rocked by a handle 86. The transfer cam abutment wheel 69 is rocked out of the way by a finger lever 103, and the drums are arrested at the normal position by studs 88 on the wheels 87 engaging stop levers controlled by springs 93. To allow for the endwise movement of drum 51 it has splines 97 to engage the wheel 87.
