Title: Electric timer switch
IPC: G04C23/16
Filed: 1954-07-02
Abstract: 758,148. Time switches. VEEDER-ROOT, Inc. July 2, 1954 [July 7, 1953], No. 19481/54. Class 38(5) A switch has a control member actuated by a driving element to perform a first contact operation, said driving element being engageable with a driven member at a certain position to cause the control member ' to perform a second contact operation. As shown applied to cooker control, the control member 64 is fixed on a shaft 62 which is biased to the left or front (Fig. 1) by a spring 66 to hold a contact 40 away from a contact 42 whose arm abuts a stop 70. The shaft also carries the driven member 110 which is slidable thereon but is rotatable therewith by virtue of a pin 128 and slot 126, the member 110 also being biased to the left by a spring 130. To set the timer, the shaft 62 is pushed to the right to allow contact 40 to return to its normal position, Fig. 2, where its arm 44 abuts the stop 70. This movement to the right also frees cams 152. 154 on member 110 from slots 156, 158 (Fig. 5) in a base member 4, so that the members 64 and 110 can be rotated through an angle dependent upon the desired cooking period. The switching-off time is set by a knob (not shown) connected through gearing to a gear wheel 80 which is thus rotated through an appropriate angle in the same direction. The movement to the right of member 110 also causes gear 80 to move to the right so that a key 100 carried by a boss 82 thereof is held against the member 64. The gear 80 is in constant mesh with a thick gear wheel driven from the knob ,and from a clock mechanism .which rotates the gear 80 back again. When the key 100 moves opposite a recess 102 in member 64, the latter is moved to the left by spring 66 to allow the contacts to close. At the same time pins 160, 162 on gear 80 and member 110 engage so: that. thereafter, member 110 and shaft 62 are also rotated until the cams 152, 154 move opposite slots 156, 158 to permit further leftward movement of shaft 62, cam 64 and member 110 to the Fig. 1 position to re-open the contacts. The contacts may be closed manually by rotating the spindle further in the same direction to an extent limited by stops 92, 164 to move a recessed portion 72 of member 64 between contacts 40, 42. Specification ' 728,105 [Group XXXVIII] is referred to.

Abstract: 235,747. White, A. E., (International Time Recording Co. of New York). Aug. 19, 1924. Multiple-indication apparatus.-An electric device for indicating the product of two quantities, such as weight and price per unit weight, comprises a pair of differentially movable elements one of which is adapted to be set to represent the multiplicand, a setting means for introducing the multiplier; and electrical means controlled conjointly by these setting means for controlling the position of the other differentially movable element to represent the product. In the arrangement shown as applied to weight and price values, the weight is set on a dial A by means of a pointer 1 either by hand or by means operatively connecting it with the indicating mechanism of a weighing apparatus and the price is set by the depression of one of a series of keys 2 whereupon a pointer 3 is automatically moved to a position indicating the total value on a dial B. The pointers 1, 3, co-operate with circular resistances 4, 5 arranged in parallel in the circuit of a battery C which circuit also contains leads 26, 29, to the armature 24 of a polarized relay D and to electromagnets E, F, respectively. The relay D has one coil 12 connected with the resistance 4 and the spindle of the pointer 1; the other coil 15 is connected with the spindle of the pointer 3 and with contact arms 18 pivotally mounted on the key stems 17. Each key 2 is provided with a pair of contact arms 18 which when a key is depressed co-operate with fixed contacts in such a manner as to shunt a corresponding resistance 20 across the coil 15 and to include a corresponding resistance 21 in series with the coil 15. The resistances 20, 21 are so designed that the total current in the circuit 13, 16 is the same whichever key is depressed. When the pointer 1 has been set and the appropriate key 2 depressed the coil 12 will influence and move the armature set to complete the circuit at the contact 25 and thereby energize the coil of the magnet E to draw the armature 30 to the left so as to rock the bell-crank lever 31 and depress the rack 33. Movement of the rack advances the pointer 3 to a position at which the influence of the coil 15 on the armature 24 neutralizes that of the coil 12 and the armature assumes its normal position. If the coil 15 has the greater effect initially the magnet F is energized to return the pointer towards its zero position. The contact arms 18 co-operate with contacts 37 so as to ensure that the key farthest to the left when depressed effects the control.
