Abstract: 25,653. Richard, C. D. Nov. 8. Money - delivering apparatus. - Relates to money-changing apparatus of the kind which operates automatically to deliver coins of a value equal to the difference between the amount purchased and the amount tendered in payment. In the example described, the machine gives change for a dollar, but machines can be constructed on the same principle for other systems of coinage. Upon a transverse shaft 1, Figs. 1 and 2, are pivoted a series of levers 2, normally held in a raised position by springs 3. Fingerlevers 5 with finger-pieces 7 are also mounted upon the shaft 1. Each of the levers 5 is provided with a pawl 9 adapted to engage a shoulder 8 on the corresponding lever 2. When a lever 2 is raised above the position shown in Fig. 2, it operates a bell-crank lever 18, which actuates a reciprocating coin bar 21. Below each lever 2 is a forked arm 15. These arms are connected in pairs to transverse pivoted beams 13<a>, Figs. 2 and 4, the sum of the coin values of complemental levers being 100 cents or one dollar. The method of operating the coin bars 21 is as follows: A dollar being tendered in payment of a 95-cent purchase, the 95-cent finger-lever 5 is depressed, thereby causing the pawl 9 to engage the shoulder 8 on the corresponding lever 2. A cam shaft 13, Fig. 2, is then rotated, and a cam 14 raises the lever 5 to its original position. As the lever 5 is raised, the lever 2 is depressed, whereupon the beam 13<a> is rocked, and complemental lever 2 is raised, and the 5-cent coin bar reciprocated. A set-screw 12<a>, Fig. 2, disengages the pawl 9 from the shoulder 8 when the lever 5 reaches the highest position. A series of coin bars 21 are provided for 5 cents and multiples thereof as shown in Fig. 1. Four coin shoots 23 ... 26 are provided, which hold 5-cent pieces, 10-cent pieces, 25-cent pieces, and 50-cent pieces respectively. The 5-cent bar 21 is connected directly to an ejecting-slide 27 mounted at the bottom of the shoot 23. The 25 and 50 cent bars are similarly connected to ejecting slides in the shoots 25, 26 respectively. The shoot 24, Fig. 6, is provided with two ejecting-slides 30, 31, each of which is directly connected to a bar 21. When one slide is withdrawn, one coin only is ejected, but when both are withdrawn two coins are ejected. The method of operating the coin shoots is as follows: For ejecting 5, 10, 25, or 50 cent pieces, the action is direct as described above. When the 15-cent bar 21 is withdrawn, an arm 32, Fig. 1, engages projections on the 5 and 10 cent bars, thereby operating them. When the 20-cent bar is withdrawn, the slide 30, Fig. 6, is operated, and the slide 31 is operated simultaneously by an arm 35 engaging a projection on the 10-cent coin bar. For other values, the coin bars are not directly connected to the ejecting - slides, but are provided with arms operating one or more of the bars directly connected. All combinations from 5 cents to 95 cents are thereby obtained with four shoots only. The apparatus may be employed in connexion with a cash register.
