Abstract

474,968. Coin-controlled savings clocks &c. DANSK SPARE-SELSKAB. June 21, 1937, No. 17247. Convention date, June 23, 1936. [Class 27] In coin-controlled clockwork-driven savings apparatus, e.g. savings clocks, savings calendars, &c., in which a control wheel 6, Figs. 1 and 2, for stopping the clockwork is turned stepwise away from its stopping position by the insertion of coins and is returned by a shifting mechanism controlled by the clockwork, the shifting mechanism comprises a wheel 10 having teeth on one-half periphery only and mounted on a shaft 12 which also carries a half-toothed wheel 11 coacting with a pawl 13 to keep the shaft 12 with the wheels 10, 11 in certain fixed positions. The wheel 10 has a pin 15 projecting at both sides, one end of the pin being attached to a spring 16 and the other end engaging and rotating the wheel 6 at each revolution of the wheel 10. The wheel 10 is rotated stepwise through half a revolution by a pin wheel 18 thereby tensioning the spring 16 until the plain part of the wheel 10 comes opposite the pin or pins on the wheel 18, whereupon the spring 16 rotates the wheel 10 rapidly through the second half of the revolution and returns the control wheel 6 through the space of one tooth. The wheel 18 is mounted on a shaft 19 having a wheel 22 driven by two pins 26 projecting from the face of a gear-wheel 24 which is connected with the spring case 23 of the clockwork. The wheel 18 has a number of holes 20 into which pins 21 can be placed for varying the rate of return of the wheel 6. Coin action, weight.-A coin dropping down a shoot 1 rocks a spring-controlled lever 2 having a leaf spring 4 which engages and rotates the wheel 6 away from its stopping position, where a pin 8 thereon actuates a lever to stop the clock. The wheel 6 has a large tooth space 9 which, in the stopping position, comes opposite the wheel 10 so that, should the clock still continue to run, the mechanism will not be damaged. When the space 9 comes opposite the spring 4, the wheel 6 will not be turned further in the forward direction, and any coins then inserted will fall direct to the money-box without jamming in the shoot 1.
