Title: Disc brake assemblies
IPC: F16D65/14
Filed: 1972-02-10
Abstract: 1312596 Hydraulic and mechanical discbrake actuators; slack-adjusting GENERAL MOTORS CORP 10 Feb 1972 [7 April 1971] 6249/72 Heading F2E A disc brake assembly comprises a caliper 12 including an actuator mechanism having a hollow piston 26 which is hydraulicallymovable and is also movable mechanically by a screw-and-nut device 46, 58, a wear adjuster comprising a sleeve 34 movable within and relative to the piston 26 to a position limiting excessive return movement of the piston due to brake wear, cone clutch surfaces 33, 35 on the piston and sleeve respectively, a spring 64 urging apart the piston 26 and the sleeve 34 and tending to disengage the clutch surfaces, and a second spring 66 placed between the piston 26 and the nut 58 of the screw-and-nut device and acting through the nut to hold the cone clutch surfaces 33, 35 in engagement-the arrangement being such that the relative movement of the sleeve 34 to a position limiting excessive return movement of the piston is effected by the second spring 66 acting through the nut 58. As shown, the caliper 12 is slidable or floating relative to a fixed member (not illustrated) and screw 46 is axially fixed relative to the caliper. The piston 26 is prevented from rotating by engagement 27, 29 with backing plate 18 which is itself not rotatable. Cone clutch surface 33 is formed on a member 32 press-fitted in piston 26. Sleeve 34 and nut 58 have concave-convex meeting faces 61, 63 and a splined connection 62. Spring 66 (see also Fig. 2) engages at its outer edge in groove 67 of piston 26. The brake is "off", though no separation is shown between pad assemblies 14, 16 and disc 10. In hydraulic operation without wear,-piston 26, sleeve 34 and pad assembly 14 are moved to the left while caliper 12, screw 46 and nut 58 are moved to the right, a gap thereby developing between surfaces 61 and 63. In hydraulic operation with wear piston 26 moves further to the left and does not return after operation to its pre-actuation position, so spring 64 causes separation of cone clutch surfaces 33, 35 and re-engagement of faces 61, 63, and the pressure of spring 66 now forces nut 58 (and hence sleeve 34) to the left by rotation around screw 46 until cone clutch surfaces 33, 35 re-engage. After this sequence, reverse rotation of nut 58 is prevented by clutch engagement and splined connection 62. In mechanical operation, screw 46 is rotated by cable-operated lever 54 so non-rotatable nut, sleeve, piston and pad assembly 14 move to the left. Screw 46 reacts through a washer 51 and caliper 12 on pad assembly 16. If wear has occurred, spring 64 disengages the cone clutch when lever 54 is returned to normal position, permitting spring 66 to advance the nut and sleeve as before.

Title: Improvements in and relating to systems of electric motor control
IPC: H02P29/00
Filed: 1925-03-11
Abstract: 240,725. British Thomson-Houston Co., Ltd., (International General Electric Co., Inc.). March 11, 1925. Systems for alternating-current motors and continuous-current motors.-The motors M1, M2 feeding wood to a pair of grinders driven by a main motor M are supplied from a voltage transformer T1 connected in opposition to a current transformer T2 which may be shunted by a choke coil (not shown) so that if the load on the motor M increases, the voltage across the motors M1, M2 decreases, causing a corresponding decrease in rate of feed of the wood. The motors M1, M2, of the compensated repulsion type, are compounded so that with increase of load on either, its field is strengthened, with consequent drop in speed, thereby keeping the output of each of these motors constant and the load on each grinder equal. Means are provided for effecting a limited reverse rotation of the motors M1, M2 when the motor M is shut down so as to relieve the grinders from the pressure of the wood. An oil-switch 0 is interlocked by a magnet Sp with the starting switch A1 of the motor M so that the stator can only be switched in when the switch A, is in its zero position. The double starting switch A2 is electrically interlocked with the switch A, and a protective device S1 so that the motors M1, M2 cannot be started until the motor M is started. When the switch 0 is opened, an auxiliary contact Sa on the device S1 energizes a device S2 to connect the motors M1, M2 to another supply Lt through a resistance W for reverse rotation which is limited bv a terminal switch E. Instead of the motors M1, M2 being single-phase commutator motors they may be direct-current compound motors supplied from a converter connected in the line of the motor M. Such an arrangement consists of a single armature rotary converter supplied by two three-phase current transformers in differential connection.
