Abstract: 950,494. Coin freeing mechanisms. C. FELDZER. July 31, 1961 [Aug. 2, 1960; Aug. 3, 1960], No. 27652/61. Heading G4V. Coin freeing mechanism for releasing services of different values has a single push member 10 which releases a service if the sum inserted is correct and controls the issue of any change required and, if the sum is incorrect, travels through the same distance but refuses the service and returns any coins inserted. The apparatus may be used for change-making, giving a large coin for small change or vice-versa. Inserted coins pass through three selectors A, B, C, Fig. 9, and are stacked on edge in a channel 35, Fig. 1, the lowermost coin resting on a surface 45, Fig. 5, on a cam 28 carried by a spindle 22. When the push member 10, Fig. 1, is depressed, a rod 3 carrying a pivoted member 13 moves rearwardly and a pivoted catch 19 engages a stud 25 to rotate the spindle 22. The cam 28, which is counterbalanced by a weight 27, is rotated clockwise and raises the stack of coins so that, if the stack is of correct height the uppermost coin engages one of several pivoted catches 41, 42 projecting into the channel 35 and raises a rod 39 on which the catches are mounted. As the rod rises, it acts on levers 43, 44 and the member 13 is rocked so that its rearward end 17 engages a fixed sloping surface 18. The cam thus continues to raise the coins and the rod operates through electrical or mechanical means to operate the article-dispenser or other service and its upper-end actuates a rocker 39<SP>1</SP> to operate change-giving mechanism. When the cam has completed its travel, it frees the coins for direction into a cash box. If the coins introduced do not form the correct payment, the catches 41, 42 are not engaged and the rod does not drive the levers 43, 44 so that the catch 19 disengages from the stud 25 and the end 17 of the member 13 moves under the fixed surface 18. The other end 16 of the member 13 engages a stud 26 and rotates the cam 28 counterclockwise so that the coins are directed to a return channel 58. A flat on the cam 28 acts on a push rod 49, Fig. 9, to open the selectors A,B,C for the return of any coins held therein and a full-stroke pawl 70, Fig. 1, ensures full movement of the rod 3. If change is necessary, the appropriate catch 42 is arranged through the agency of a block 57, Fig. 11, to raise one or other of two rods 38, 40, Fig. 1, together with the rod 39; these rods 38, 40 are arranged to operate rockers 38, connected by cables to change mechanism 51. A cylinder with a stud on its lower end may rest on the coins in the change mechanism and when a coin channel empties the stud enters a hole at the bottom of the channel and prevents operation of the whole apparatus. For varying the amount of change returned for different selected operations, projections 90, Figs. 12 and 14, are locked in groups at adjustable positions on a cylinder 82 and the cylinder can be set in various angular positions by a selector knob. The knob is carried by a spindle 85 geared to the cylinder 82 and the cylinder is mounted in levers 89 rotatable on the spindle 85 so that a releasing member 103 connected to the coinfreeing mechanism can tilt the levers into a position where the projections 90 can contact levers 98 which control change returning levers 104 set by the coin freeing mechanism. Cams 96 are also mounted on the cylinder 82 and operate push members 97 which release one of the operations of the apparatus. A toothed wheel 95 also on the cylinder engages one of its teeth in a slot 162 and locks the cylinder against rotation. As the selector knob is rotated to correspond to higherpriced operations, cables connected through springs to the catches 41, 42 representing lower prices are wound on the cylinder 82 and disable the lower-price catches.
