Abstract: 298,668. Nixon, C. W. July 14, 1927. Money - delivery apparatus. - A control mechanism for coin-controlled machines of the kind requiring the deposit of a purchase coin before the machine can be operated comprises a sliding carrier with one or more relatively movable coin clamping slides of various sizes adapted to receive a deposited coin which is gripped by a slide on the initial movement of the carrier so that a hook draw-bar on the slide engages bellcrank lever device and a goods ejector. The carrier is moved by the engagement of a pull-bar 61 with a lever 38 operated by a handle 32 and comprises cross pieces 44, 45, Figs. 5, and 8 connected by strips 46, 47, 48, the cross pieces being provided with shoes 49 slidable on rails 50 and the strips 46, 48, are connected by a yoke 56; springs 57 being connected to the yoke and to a support 52 whereby the carrier is retracted against an abutment 59. Associated with each strip is a coin-controlled unit including a head 62 and a slide 63 forming a coin-space which may be adjusted by means of a pin 74 on the slide and an adjustable bolt 75 secured in a plate 76, Fig. 8. The slide 63 is provided with a pin 68 slidable in a slot 69 on the strip 46, a spring 72 being connected with the pin 68 and with a pin 73 on the strip so that the slide is drawn toward the head to clamp a coin or coins in space 65, the coins being advanced from the abutment. The head 62 may be pivoted and the coin space adapted to hold two coins, a counterbalance weight 92 being connected to the head to facilitate the expulsion of the coins as the slide is withdrawn. When a coin is dropped into one of the coin-spaces and the pull bar 61 is moved laterally the hooked drawbar 77 on the slide engages, at the end of the stroke, with the bell-crank 27. On the return stroke the load on the arm 26 of the bell-crank causes the slide 63 to overcome the tension of the spring 72 to release the coin which drops into a receptacle. The upward movement of the arm 26 raises a sleeve 25 and an attached rod 82. which strikes a ledge 83 on the pull-bar 61 to release the latter from the draw-lever 38, the springs 57, in combination with a dash-pot, then draw the carrier against the abutment 59. As the slide near the abutment a projection 81 strikes the draw-bar 77 and releases it from engagement with the crank 27. Each slide is locked to its strip in the extreme position of the carrier when no coin is in the coin space. Each slide has a. button key 85 held by a spring 86, the head of the key being seated in an aperture 88 in the strip so that when the head of the key slides down declivity 89 of the guide the spring will push the stem of the key through aperture 88 and into aperture 90 in the slide. The key is withdrawn on reverse movement. A locking device Figs. 3, 4, to prevent the handle 32 being depressed until a coin has been dropped into one of the coin-spaces, comprises a plunger 100 projecting normally below the handle 32, Fig. 4 and connected by rod 102, bell-crank 103 and rods 105, 106 to one of three cams 108 mounted on a shaft 109. Each slide has an extension 110 with cam head 111 and when a coin has been dropped into one of the coin spaces, the slide of that unit, on the initial down stroke of the handle will move under its corresponding cam to rotate the shaft 109 thereby withdrawing the pin 100. Change-giving.-The bell-crank 27 in its movement, operates ejectors 30 for discharging change from banks 14 into the receptacle 31, Fig. 1. Storage.-A casing 10, Fig. 1, contains a rotary skeleton magazine 11 which includes an upper spider 12 with a ring 13 supporting a series of change-banks 14 and a lower spider 15 with a ring 16 supporting a series of goods-holders 17, 17<1>, from which the goods are discharged into a receptacle 18 by an ejector 19 operated by links 20 - - 27 when one of the three cranks 27 is moved by the carrier. An operating handle 32 is mounted in a bearing 33 of a forked member 34, pivoted at 37 to a bracket 35 and is adapted to be rotated and depressed. When rotated a pin wheel 36 engages a gear wheel 36<1> to rotate a shaft 28 and with it the magazine 11. When the handle 32 is depressed a bell-crank 40, pivoted to the bracket 35 at 41 and to the forked member 34 at 42, operates a lever 38, pivoted at 39 to the bracket by means of a link 43 to draw the pull-bar 61 laterally to move the carrier. Specification 298,666 is referred to.
