Title: Improvements in flushing cisterns
IPC: E03D1/30
Filed: 1920-11-02
Abstract: 171,611. Saville, G. A. Nov. 2, 1920. No Patent granted (Sealing fee not paid). B a l l and float valves.-The cistern 1 is fitted with a cylinder 2 for the reception of a piston 8 slidable on the spindle 9 of a float 10 which operates the inlet valve 11. The cylinder walls are continued upwardly by a cylindrical guide 17 having ports 18. When the cistern fills, the float 10 raises the piston in the cylinder causing a partial vacuum therein, the perforated bottom of the cylinder being fitted with a non-return valve 6. To give a flush, an air valve 5 is operated, air passes into the cylinder, and the piston rises up the spindle 9 and uncovers the ports 18. The contents of the cistern thereafter pass through the ports and the valve 6 to the closet. The piston is held in raised position by the device shown in Fig. 2. A spring-pressed ball engages a recess 26 in the guide 17. As the cistern empties, a float arm 22 descends and brings a pivoted cam 24 to bear on the ball and force it out of the recess so that the piston may fall again. The inlet valve spindle 12 is provided with a guide 13 carried by the cover 20.

Abstract: 688,032. Friction clutches. DELPRO SOC. AR.L. Dec. 2, 1949, No. 31007/49. Class 80 (ii). A centrifugal friction clutch comprises a pair of arcuate friction bands 22 engageable with a driven drum 19, one end 22a of each band being connected to the driving housing 15 while the other end is connected to a lever 1 pivoted at 23 to the housing 15, another arm of the lever 1 pivotally carrying an arm 7 connected by a link 12 to a centrifugal mass 2 pivoted at 27 to the housing 15, the free end of the arm 7 carrying a roller 10 engaging a cam slot 3a in a part 3b projecting from a ring 3. The latter is rotatable in the housing 15 under the control of a spring 4d mounted in a cylinder 4a and acting on a piston 4b whose stem 4c is connected to the part 3b, the cylinder 4a being pivoted at 30 in, the housing 15 and having an arm 28 carrying a roller 31 engaging a guide slot 3c in a projecting part 3d of the ring 3. The arrangement is such that, below a predetermined speed, the parts occupy the full-line positions shown in Fig. 1, the moment of the forces acting on lever 1 due to the centrifugal force of the mass 2 and to the spring 4d being zero, so that the clutch is disengaged. Above that speed, the mass 2 moves outwards and the ring 3 turns clockwise, whereby the moment of the forces acting on the lever 1 becomes very large, and the clutch surfaces are engaged under high pressure. The clutch may be cooled by, air drawn in through holes in the housing 15. The movement is damped by oil in the cylinder 4a, and the degree of damping during clutch engaging movement may be varied by means of a longitudinallyadjustable rod 41, Fig. 8, in a bye-passage 40 between the ends of the cylinder, while ports 37 in the piston 4b, controlled by a spring-loaded valve 35, allow free return movement of the piston. There is a ball-and-socket joint 33 between the piston and its stem 4c, and the latter has a conical face 49 seating in a conical recess in the cylinder end in the clutch-disengaged position. A filling plug 52 for the cylinder carries an adjustable rod 51 to limit the stroke of the piston.

Title: Improvements in or relating to servo-control means for hydraulic gears
IPC: F16H61/40
Filed: 1936-11-17
Abstract: 485,011. Servomotors for hydraulic gears. BISCHOF, B. Nov. 17, 1936, No. 31425. [Class 135] Relates to servo-control means for hydraulic gears in which the proportion between the mechanical and hydraulic output is regulated by piston stroke variation by the mutual displacement of two eccentrics mounted one over the other. The servomotor comprises two meshing gear-wheels 42, 43 forming the elements of a gear wheel pump and designed to rotate in opposite directions gear-wheels 31, 32 which in turn operate the eccentrics which regulate the piston stroke of the motor-element of the gear. The hand adjustment of the lever 50 causes displacement of the regulator valve 44 and the consequent admission of pressure fluid from the pressure chamber of the gear through the tube 49 and one or the other of the conduits 46, 47 to the corresponding side of the gear-pump and consequent adjustment of the eccentrics. A roller 55 on a lever 53 pivoted at one end to the casing and intermediately to the lever 50 works in a guide groove 56 in the gear-wheel 32, this gearing resulting in the valve being brought back to the position in which it blocks the conduits 46, 47. In a modification, the adjustment is automatic with an over-riding hand control. In this arrangement the lower face of the piston 59, Fig. 8, is subjected to the pressure in the pressure chamber of the gear through the pipe 58. A pin 61 on the piston rod controls through floating lever 50 the position of the regulator valve. To eliminate the effect of the pressure in the suction chamber of the gear with which the make-up pump 66 is connected, this pressure is conveyed to the top face of a piston 67 of equal size to the piston 57 and arranged at the opposite end of its piston rod.
