Abstract: 1,211,102. Clutch-brake combinations; friction clutches; cooling disc brakes. U.S. INDUSTRIES Inc. 6 Dec., 1967 [7 Dec., 1966], No. 55578/67. Headings F2C, F2E and F2L. A drive mechanism e.g. for a press comprises a housing 5 bolted to the frame 25 of the press and having a drive shaft 2 and a hub 13 journalled therein at opposite ends, the hub 13 carrying a flywheel 6, which may be belt driven, and enclosing a hydraulically operated plate clutch and brake unit 7, 8 carried by the shaft and having sets of plates 44, 38 respectively splined to the hub and housing. In the position shown the brake 8 is held operative by springs 51 acting on one part 47 of a central double piston 47, 48 to lock shaft 2 to the housing 5, flywheel 6 being freely rotatable. Actuation of the piston 47, 48 by fluid entering cylinder 50 compresses springs 51 to release the brake and the piston engages clutch 7 to cause the flywheel to drive the shaft. On removal of the hydraulic pressure, springs 51 disconnect the drive and brake the shaft. If the piston 48 is now expanded by hydraulic fluid entering chamber 55, part 48 of the piston engages clutch 7 but, as brake 8 is operative, the clutch acts as a brake on the flywheel. Removal of the hydraulic pressure from chamber 55 causes the piston to contract under springs 59. Fluid enters the cylinder 50 and chamber 55 selectively via passages 63, 64 in the shaft from a rotary seal 60 coupled to inlet pipes 61, 62. Cooling and lubricating oil enters the mechanism through a passage 81 and after passing through the bearings and the brake and clutch unit discharges through opening 109.

Abstract: 1388106 Random selections D RENOWDEN and J BENGHIAT [trading as HAMILTON] 22 Feb 1972 [26 Nov 1970] 56328/70 Heading G4D In apparatus for playing bingo or the like each player position has an extra lamp, these lamps being periodically energized in a continuous sequence until either the end of a time period or the completion of the game; if the last energized lamp coincides with the winner of the bingo game a larger prize is given. When a bingo game is started by energizing a pneumatic number ejector or "blower" motor, a relay X is energized. This de-energizes a flasher relay F but energizes a timer relay T and a motor DM which drives a rotary selector switch. The latter comprises a double sided printed contact stator (Figs. 2, 3, not shown), and a rotor carrying ten wiper contacts (Fig. 4, not shown). The stator has five concentric slip rings and two concentric sets of fifty contacts connected to fifty player positions. Eight of the wiper contacts WB-WE, RW2- RW5 connect four slip rings R2-R5 to four adjacent contacts LC of one set so that four lamps are lit at time in sequence. The other pair of wipers WA, RW1 connect the fifth ring R1 to one of the other set of contacts SC; the respective contact SC is only energized when the player position is in use, i.e. a fee has been paid. When the timer relay T releases contact T1 or the blower relay X releases contact X1 the motor DM stops at the next contact (by homing switch DMS), and the flasher relay is energized to flash the lamp then selected by wiper WE (the other three lamps can also flash if push buttons LPB are operated). If the selected player position is in use a sound relay S is energized and sounds a bell, &c. CH. Thus the lamps flash in a sequence until the end of the game when one or more of the lamps then alight continues to flash and if that player position is in use a bell sounds.
