Title: Improvements in hydraulic clutches
IPC: F16D31/06
Filed: 1934-10-06
Abstract: 449,897. Hydraulic transmission of power. LEE, H. C., 3, Station Parade, North Ealing, London. Oct. 6, 1934, No. 28645. [Class 69 (ii)] A hydraulic clutch comprises a shaft provided with a slidable vane which may be pressed outwards into contact with the inside of an eccentric cylinder, the action being controlled by moving the shaft axially. In the position shown in Fig. 4, the vane C is held in by contact with the bearing F, and a byepass passage M in the shaft is in full communication with the cylinder K. When the shaft B is moved upwards, the vane and its guide S are moved together with it until the vane is free of the bearing F, when it is pressed out by springs P<1>, P<2> and liquid pressure caused by a spring- pressed piston R. The byepass passage M is still fully uncovered so that the clutch operates with maximum slip. Continued axial upward movement of the shaft is independent of the vane and its guide, and the passage M is gradually covered by the bearing G thus reducing slip. Finally, a solid drive is effected by a spring- loaded member H engaging a slot Z in the shaft as shown in Fig. 1. The clutch can then be disengaged by either upward or downward movement of the shaft. In order to limit the pressure on the blade during hydraulic drive, its edges are bevelled at V<3>, V<4>, Fig. 1, so that during parts of each revolution, liquid may pass from the front to the rear through byepasses T<1>, T<2> in the guide S. Leakage is made up through a channel X.

Abstract: 730,051. Cutting glass. PILKINGTON BROS., Ltd., and DENLOW, P. M. Nov. 13, 1953 [Nov. 14, 1952], No. 28830/52. Class 56. Glass ribbon, emerging upwardly from the annealing chamber of the drawing apparatus, is scored both longitudinally and transversely and, in order to prevent premature division along the longitudinal lines when the ribbon is snapped along the transverse lines, the former are interrupted adjacent the points at which they would otherwise intersect the latter. The transverse scorer is operated when the leading edge of the rising ribbon engages a switch, not shown. The longitudinal scorers 17 normally engage the ribbon but when the leading edge engages a switch 42, earlier than it engages the switch controlling the transverse scorer, it closes a circuit to open a valve 56 to admit fluid pressure to a cylinder 60, thereby causing a rod 63 to rise and swing a bail 30 to move the scorers 17 out of contact with the glass. The scorers return to contact after an adjustable time by means of a trip member 70, operated by the rising rod 63, freeing the notched arm 51 from the lever 53 controlling the valve 56 thereby permitting the latter to close and the rod 63 to descend and rock the bail 30 in the reverse direction. Specifications 456,822 and 634,553 are referred to.
