Abstract: 821,411. Control of motors. HOOVER, V. A. Jan. 31, 1956, No. 3042/56. Class 38 (3). [Also in Groups XXX and XXXIII] A linear actuator is provided with a load limit switch which disconnects the drive from a motor when the screw of the actuator engages a mechanical stop, the switch being rendered inoperative until the screw engages an electrical limit switch on approaching the stop. As shown, Fig. 3, a nut 40 is rotated in bearings 42, 43 by a motor 80 through gears 82, 83, 85, 86, the gears 83, 85 being carried on a shaft 84 in bearings 87 which are adapted for axial movement. Screw 50 is provided with stops which engage stops on the nut at the limits of travel of the screw, stopping the gear 86. Gear 85 is helical and tends to slide axially against a spring 95 when the gear 86 is stopped, opening a limit switch 98 and de-energizing the motor 80. Outer and inner limit switches 110, 120 are normally closed and short out the load limit switch 98, but are opened as the screw approaches a mechanical stop by a cam 64, on a tube 55 connected to the screw and slidable over the nut 40, which engages arms 114, 122 on the switches. On closing " retract " switch 26, Fig. 2, current passes from a D.C. source 162 through lead 161, energizing the coil of a relay 169 to close contacts 168 and energizing the motor 80 through " retract " winding 164. After the cam 64 has opened switch 120, the motor is under the exclusive control of the load limit switch 98. As shown in Fig. 2, a crossconnection is provided between the circuits of two actuators for energizing auxiliary brake releasing coils 155 when the corresponding motor 80 has failed. In a further embodiment, Fig. 12, the actuator is adapted to be stopped in an intermediate position, and the thrust applied by the actuator is limited to a predetermined amount. Limit switches 380-383 are operated by cams on a shaft 394 rotated by arms 390, 391, which are pivoted about an axis perpendicular to that of the screw 336 and are rotated by a cam ring 389 mounted on a sleeve 341 connected to the screw 336 and slidable over the nut 332. Specifications 706,382, [Group XXIV], and 821,413 are referred to.

Title: Improvements relating to scoring apparatus for games
IPC: A63B71/06
Filed: 1938-02-04
Abstract: 498,431. Coin-freed game apparatus. COOKE, G. H., and BAINES, R. H. Feb. 4, 1938, No. 3626. [Class 27] [Also in Group XV] Relates to scoring apparatus for games in which scoring results in stepping forward a disc or other member to an extent corresponding to the score, the disc being eventually returned to its initial position, the attainment or passing of a predetermined score resulting in an electric contact on the disc closing a circuit to give a signal or effect some operation. The signal or operation may be the lighting of a lamp ; or in an apparatus for a bagatelle or shooting game, a further ball may be released for play ; or in a coin-freed machine the player's coin may be returned. The invention consists. in providing a switch operated in such a manner by means for effecting or causing the return of the disc to its initial position as to avoid the indication being given again or the operation being repeated as the result of the return movement of the disc. As shown, for use in a bagatelle type of game wherein balls projected from a side channel bump against electric contacts and produce electric impulses in a solenoid 11, the core of the solenoid actuates a lever 9 and pawl 81 to rotate a ratchet wheel 8 and give successive movements to a scoring disc 4 perforated with numbers n which are optically projected on to a screen. An electric contact 6 is secured in one of a series of holes 5 corresponding to the score numbers. When the score disc has been stepped forward a predetermined amount, the contact 6 engages and subsequently passes a resiliently-mounted contact 7 thereby closing a circuit to illuminate a signal lamp 19 or to effect some operation. The return of the scoring disc 4, under the influence of a spring 12, is prevented by a pawl 13 until the pawl is freed from the ratchet wheel 8 by a solenoid 16 which may be energized by a press-button, by the weight of balls accumulating in a magazine, by an inserted coin or bv movement of the coin slide. The solenoid plunger 15 operating the holding pawl 13 is normally held by a spring 14 in a forward position so as to close two spring contacts 17, 17<1> in series with the signal lamp 19. When the solenoid plunger is drawn back to release the holding pawl 13, the contacts 17, 17<1> open the lamp circuit and prevent a second signal (or further operation) when the contact 6 passes the contact 7 during the return of the scoring disc 4. Specification 498,426 is referred to.
