Filed: 1923-06-23
Abstract: 222,191. Constantinesco, G. June 23, 1923. Addition to 205,293. Variable-speed ratchet gearing adapted for oscillating members of high frequency, and comprising intermediate cam-urged friction or positive grippers or pawls such as g, Fig. 5, is modified by the interposition of balls or rollers such as c between the gripper g and the oscillator f. In the arrangement shown in Fig. 5, the cam action for thrusting the gripper g against the rotor o is obtained by inclines similar to the inclines b, Fig. 2. The gripping face of the gripper g, Fig. 5, may have small teeth, or may be provided with a friction pad. When the friction is obtained by metal-on-metal, the gripping surface is preferably castellated as shown at n, Fig. 7, so that oil may be pressed out from between the gripping surfaces. In the construction shown in Fig. 16, the grippers 42 are pivoted members thrust outwards by the balls 46 in arcuate recesses in both the oscillator 43 and the grippers. Arrangements are described in which the pivoted grippers are thrust inwards against the rotor. Specification 217,684 is referred to.

Title: Improvements in and relating to hydraulic pressure systems
IPC: B60T13/12
Filed: 1937-06-14
Abstract: 497,226. Hydraulic transmission of power. BENDIX, Ltd., and ROBERTS, G. P. June 14, 1937, No. 16408. [Class 69 (ii)] [Also in Group XXXIV] An hydraulic pressure system, more particularly for brakes, comprises a spring-loaded servo-mechanism automatically brought into action when the hydraulic pressure exceeds a predetermined value. The master cylinder is connected at 13 and the brake cylinders at 39 so that the braking pressure is transmitted by passages 21, 22 and past a valve 26. The mechanical servo comprises springs 56 connected to trunnions on a thrust member 46 and pivoted at 48 to the casing. The thrust member is adapted to exert pressure on the hydraulic system by means of a spring 47 and a piston 36. The springs 56 are substantially at right-angles to the thrust member but slightly off-centre so that the axial component acts in the releasing direction. Pressure fluid from the master cylinder acts also on a piston 28 connected to the valves 26 and to a cylindrical part 25 acting as a stop for a peg 33 extending from the piston 36. When during brake application this pressure is sufficient to overcome a spring 31, the piston 28 is forced down, closing the valve 26 and moving the stop 25 down so that apertures 35, 64 are aligned in the path of the peg 33 and no longer stop the movement of the thrust member 46. Pressure fluid from the master cylinder which acts also through a pipe 17 on a piston 53 and the thrust member 46 now moves the thrust member to the right, the springs 56 are moved past their dead-centre and their horizontal component exerts pressure on the piston 36 and thus on the brakes. When the brake pedal is released, the piston 36, thrust member and springs 56 are returned to release position by the pressure in the transmission system, and the valve 26 and the stop 25 are returned by the spring 31. The valve 26 comprises a cup leather seal, which enters and closes the cylinder 23 containing the piston 28, and is enclosed by an inverted cup 26b which is slidable against a spring 26c and engages a seating 24. The cup is adapted to guide and protect the cup leather seal.

Filed: 1946-05-30
Abstract: 626,860. Seaming non - metallic sheets. BLAND, A. H. May 30, 1946, No. 16409. [Class 42 (i)] [Also in Groups XV, XVI and XVII] A machine for joining sheets of cellulose or like sheet material comprises a pair of jaws between which the sheets are clamped, the operating faces of the jaws being provided with complementary pyramidal projections and indentations. Lower and upper jaws 18, 20, Figs. 4 and 6, whose operating surfaces are formed respectively with pyramidal projections 42 and indentations 44 of complementary form, are carried respectively on a base 10 and a movable part 14 of a machine, hinged together at 16. Each jaw comprises a channel 30 of aluminium or an alloy thereof, and is screwed to a block 37 secured to the machine by screws 39. A resistance element 32 enclosed in asbestos 34 passes out of the jaw at either end to form a cable, whereby the jaws are electrically heated if required, as when the sheets to be crimped are thermoplastic. The jaws are normally held closed by adjustable springs 22 on the base 10 and acting through cables 78 attached to shackles 82 on arms 68 pivoted at 70 to the part 14. An electric motor 50 on the base drives pinions 62 through reduction gearing 54, and the pinions engage gear-wheels 60 mounted eccentrically on spindles 66 carried by the arms 68. On operation of the motor, the spindles 66 rise along the curved path 84, whereupon U-shaped brackets 86 carried by the spindles abut against stops 88 to open the jaws, the stops 88 being adjustable to vary the length of time the jaws remain open. Alternatively, the parts 10, 14 may be urged apart by a spring, and a handle or foot-pedal may be used to lower the part 14 and close the jaws. According to the Provisional Specification, a thermostatic device may be employed to control the heating of the jaws, and an interlock may be provided in the motor circuit to open the jaws when the motor is switched off, which may be a solenoid operating a cam; in another form, a fractional horse-power motor has a cam on the driving shaft to open the jaw against spring pressure, the motor speed being adjustable according to the sealing rate required.

Title: Improvements in or relating to electric temperature control systems
IPC: G05D23/24
Filed: 1949-06-21
Abstract: 662,492. Automatic temperature control systems. ROBERTSHAW-FULTON CONTROLS CO. June 21, 1949, No. 16490/49. Class 38 (iv). A temperature control system, particularly for a cooking oven, comprises a temperaturevariable resistance 24, Fig. 1, of negative temperature coefficient, responsive to the temperature to be controlled, connected in parallel with an electromagnetically-operated valve 18 which controls the supply of fuel to a burner 10. Connected in series with the parallel circuit is a temperature-variable rheostat 26 for presetting the operating temperature, the rheostat being set manually together with a main " onoff " valve 16. If the temperature increases the resistance of 24 decreases, the current flow through the coil of valve 18 decreasing also until at the predetermined temperature the current flow through the coil is insufficient to maintain the valve 18 open and the fuel supply is cut off. As the resistance 24 decreases, the current flow through rheostat 26 increases, increasing its temperature and therefore its resistance, thereby preventing excessive current flow. In a second embodiment, Fig. 2, the coil of valve 18 is replaced by the coil 52 of a relay 50. The relay 50 has an armature 54 which connects an electric heater 48 to the supply. An " onoff " switch 62 may be operated by the rheostat 26 control knob if it is desired to break the supply line when the system is inoperative.
