Abstract: 203,521. Vickers, Ltd., McKechnie, Sir J., and Bateman, L. H. Sept. 8, 1922. Force-transmitting mechanism; band or coil; electric and magnetic. -In brakes of high-speed shafts, two brake drums mounted loosely on the shaft are connected to it by gearing in such a way that during rotation of the shaft, and during application of the brakes, relative rotational movement is caused to take place between the drums at a comparatively slow peripheral speed. In this way braking is effected at slow speed, and excessive wear and generation of heat is avoided. The Figures show the application of the brake, to the high-speed shaft A of the electrical driving mechanism described in Specification 195,654, [Class 38 (iii), Electric motor control systems &c.]. The shaft has webs carrying a crank pin D<1> on which is mounted a toothed pinion D meshing with teeth on both of the brake drums B, C, which are loose on the shaft. The teeth on the drums are unequal in number. The part A<1> balances the weight of the pinion. Two brake bands B<1>, C<1> are provided, the fixed ends being secured to a pin e in a bracket E, and the movable ends being attached to the end F of a bellcrank lever F<1> which is actuated by a solenoid G through a rod g on which are arranged a pressure-regulating spring G<x> and a lighter release spring g<x>. The solenoid may be controlled from the switch which controls the motors. In operation, the brake bands are applied with equal pressure, and one brake drum is held stationary while the other tends to move at low speed. The arrangement may be modified by fixing one of the drums B, C and dispensing with its brake band.

Abstract: 402,901. Valves. KENT, Ltd., G., and JACKSON, E., 199, High Holborn, London. Sept. 2, 1932, No. 21525. [Class 135.] The supply of gas to a hot-water boiler is controlled by valves 8, 16. A handle 10 pivoted to the stem of the valve 8 has a lug which can engage any one of three notches in the valve casing. In the position shown, the valve 8 is closed, but a small port 18 allows gas to pass from the gas conduit 4 to a pilot burner 19. In the second position of the valve 8, ports 13, 14 register with conduits 4, 5, respectively, and gas passes directly to the boiler through outlet 3. This is the position of the valves when it is necessary to heat up the boiler from the cold state. In the third position of the valve 8, ports 13, 15 register with ports 4, 6, respectively, and the port 5 is shut off. A by-pass 7, connecting ports 5, 6, permits sufficient gas to pass to the boiler to maintain the water warm. The valve 16 is mechanically connected to the hot water draw-off cock and is arranged to open as water is drawn from the boiler, so that gas passes directly from the port 6 through the valve 16 to the boiler. The by-pass channel 7 may have a screw for adjusting the opening therethrough.

Abstract: 642,079. Switches held set and freed mechanically. PAILLARD SOC. ANON. Sept. 22, 1948, No. 24755. Convention date, Oct. 16, 1947. [Class 38(v)] A switch comprises a contact-carrying rotor which can be moved in turn to a number of service positions in which it is resiliently locked against the action of a spring tending to restore it directly to normal, release being effected by pressing the rotatable actuating member to slide the rotor axially and separate the parts of a clutch connecting the rotor and resilient locking device. A tension spring 19 is compressed between the rotor 20 and the base 1, the ends 28, 29 of the spring engaging, respectively, in holes 51, 53 in the base and rotor. The latter is located in its various positions by means of blade springs 39, 40, co-operating with a square block 38 secured to a disc 45 having holes 46 engageable by pins 31 on a clutch member 30 fixed to the rotor. The switch is operated to its service positions in turn by a knob 34, movement of the rotor being limited by lugs 32, 33 on clutch member 30 engaging parts 44 of the springs 39, 40. Depression of the knob 34 disengages pins 31 from holes 46 and allows the spring 19 to return the rotor to its normal position, in which the contacts 5, 23 and 7, 25 are in engagement, Fig 2. The contacts 23, 25 and a further contact 24 are bent down from radial portions of an annular ring 22 lying in a groove on the underside of the rotor.
