Abstract: 348,313. Coin-freed apparatus; moneydelivering apparatus. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., Pennywell Road, and DOLMAN, H. J., Rondray, Church Road, Staple Hill, Bristol. March 29, 1930, Nos. 10032 and 33075. [Classes 27 and 116.] In change-giving apparatus an inserted coin is caused to effect a mechanical connection between a continually actuated element and the change delivery mechanism. The latter may be positively driven in one direction against a spring &c. which then acts to return it to its initial position. The apparatus may also deliver an article or print and issue a ticket. In one form, Figs. 1, 2, the coin itself forms a connection between the change delivery mechanism and the reciprocating member. A slipper 14, Fig. 1, is reciprocated in a track 13 through a connecting rod 8 by a continuously driven disc 6 ; when the slipper is at the righthand end of its travel a projection 16 engages one end of a spring-controlled bell crank 43 so that a pin 45 is withdrawn to permit passage of a coin from the insertion slot 39 to the position 38. When the shoot 40 is obstructed by the pin 45 a member 5 assumes the position shown in dotted lines and the arm 52 serves to deflect any subsequently inserted coin to the passage 41. On forward movement of the slipper an extension 20 thereon engages the coin 38 and through an extension 29 a slide 27 is moved forward against a spring 57 to expel a coin from a receptacle (not shown). At the end of this forward movement an abutment 65 on the slide is engaged by a projection 63 on an arm 61 and the slipper 14 returns allowing the coin to fall through an aperture 82 and the projection 16 lifting the roller 66 on the arm 61, thus releasing the slide to return under the action of the spring 57. During the 'forward movement of the slide 27 a pin 55 thereon engages a pin 54, on a slide 26 which is thus moved against a spring 56, oscillating a spindle 32 through the rack teeth 30. A star wheel 33 is thus driven through a uni-directional device to eject a predetermined number of coins from a container 78, while at the extreme forward position a lever 79 may be moved to actuate a device for delivering an article or for printing and issuing a ticket. The return movement of the slides is limited by stops 58, 59, and the position of the former may be adjusted to vary the lost motion between the slides and consequently the number of coins ejected from the container 78. A further insertion slot is provided to deliver a coin of smaller denomination to the position 83 and to effect delivery of change from the container 78 only, while a number of reciprocable slides inter-connected by studs similar to 54 and 55 may be provided to be actuated by coins of different denominations. In the forms shown in Figs. 5, 6 and 9 the inserted coin co-operates with mechanism to effect a mechanical connection between the continuously actuated element and the change-delivery mechanism. In the form shown in Fig. 5, at the extreme right-hand position of the slipper 14 a member 90 is moved into the shoot 93 by a pivoted, spring- controlled lever 91 to thrust a coin to depress one end of a bell crank 98 ; a second bell crank 88 is thus moved to allow a member 86 to assume the position shown in dotted lines and thus to effect a connection between the change-delivery slide 26 and the continuously actuated slipper 14. A member 104 controlled from the member 90 is provided to control admission of the coins. In another form, Fig. 6, a coin falling down a shoot 109 depresses one end of the lever 107 and thus frees the bell crank 86 to effect connection of the slipper and slide. In Fig. 9 the lever 107 is depressed by a coin inserted in the shoot 109 against a counterweight 115 and engages with a finger III flexibly mounted on the bell crank 86. Coin-testing mechanism that takes an appreciable time to operate may be provided in the insertion slots.
