Abstract: 26,275. Shaw, E. Dec. 1. Sale apparatus. -Goods of various kinds are stored in bulk or in packets in the same casing, and a weighed quantity or a packet of any kind is obtained for the same coin by means of a single actuating-mechanism. The invention comprises improvements on the inventions described in Specifications No. 18,748, A.D. 1898, Nos. 10,375 and 25,479, A.D. 1901, and No. 15,438, A.D. 1902. Storage.-As in the invention described in Specification No. 25,479, A.D. 1901, the goods in bulk are contained in rotary drums a, Fig. 4, which, when turned, deliver some of their contents to an endless band conducting it to the scale-pan d. The goods in packets are piled in upright compartments arranged right and left of the drums on girders 63. Samples of the goods are shown. Actuating-mechanism ; coin action.-A hand-wheel u having its long boss v turning in a bush v<1> in the casing front, turns an eccentric 2, from which motion returns through a side lever 4, Fig. 6, to a concentric lever 7, having a head with two pockets 8, 99, to receive a coin from one of two short shoots 9. The coin enables the lever to operate - one of two companion levers 12, 107, and with the operation of the former a slotted lever 20, Fig. 12, engaging a pin on its foot 15, shifts a clutch w so that a hollow shaft h is turned by the handwheel. Coin-discharging mechanism ; coin-slit closing- devices.-Catches 17, 103, Figs. 4 and 6, hold the displaced companion levers, while the coin lever 7 retreats and lets the coin drop. The coin lever has a wing 11, Fig. 6, to close the coin shoots while acting. Delivery mechanism.-Some lantern-pinions g on the hollow shaft h gear with the storage drums, and any one of them is clutched to the shaft by turning an inner shaft containing pawls k, Fig. 7, which spring out through slots i, o, the former in line and the latter disposed spirally. The pointer t by which the inner shaft is turned shows the commodity selected on a dial r on the outer shaft. The companion lever 12 operates a rack-rod 51 which closes the hinged bottom 47 of the scalepan d, while a cord 58 from the lever partially rotates a feed-roller for wrapping- paper as described in Specification No. 15,438, A.D. 1902. With the continued rotation of the hand-wheel, the clutched pinion turns the corresponding storage drum, and a cord 56 gives motion to the endless band inside while an eccentric 55 works the paper-delivery device. An arm on the axis of the catch 17 is loosely connected by a rod 31 to a light bracket 33 on the scale-beam, and when the latter tips, the rod having a lug is applied to a ratchet-collar 35 on the hollow shaft so that further rotation disengages the catch from the companion lever, which is accordingly pulled back by a spring so opening both the scale-pan and the clutch. In the delivery mechanism for the packets, a pusher 88 is provided at the bottom of each goods compartment 60, Fig. 18. A hollow split shaft 84 runs behind them, and an arm 91 on it is connected by a cord 92 to the arm 94, Fig. 6, of the front companion lever. A pair of arms project from the split shaft, and are connected by external and internal rods 96, 97. One of the arms is brought into register with the pusher for the desired goods by means of a rack and pinion at the front of the machine, and the hand-wheel is turned till the ejected packet is brought to the central exit by an endless band 61 in front of the compartments, which is driven by an endless cord from a pulley 66. A pin 106 on the eccentric trips the catch 103, to let the lever and split shaft be reversed by springs pulling on the attached arm. Fraud, preventing ; money shoots.-Teeth z on the clutch are normally engaged by a pawl 1. The coin shoots 9 have oval holes 38, to let undersized coins drop out and return by a lower shoot 39. The discharged coins run down a shoot 41, Fig. 6, to au endless exhibiting-chain 42, for the advance of which a sliding pawl 44 is connected to the companicn levers by a link 45.
