Title: Improvements in or relating to pneumatic braking devices for a rotating element
IPC: B60T8/20
Filed: 1941-10-31
Abstract: 555,311. Brakes. BOBST & FILS, SOC. ANON, J. Oct. 31, 1941, No. 14058. Convention date, Nov. 18, 1940. [Class 103 (i)] In a braking device for a rotating member in which the braking action is produced by the compression of a gas in a cylinder or equivalent, maximum compression is arranged to be effected when the crank and connecting rods by which the piston is operated are at right angle to each other and to permit the continuation of the rotation of the rotating member beyond this position the cylinder or a second piston on which the compression reacts is withdrawn. In Fig. 2, air is compressed in a cylinder 5 by a piston 4 actuated through a crank and connecting rod 6, 2, by the rotating member to be braked. A second piston 8 is actuated, for instance, by a cam in such a manner that maximum compression is effected when the crank and connecting rod are at right angles as shown, the piston 8 being subsequently withdrawn to permit continued rotation of the member 1. Instead of providing the piston 8, the cylinder may be reciprocated. In Fig. 4, the member 1 is rotated by a sector 12 oscillated by the part to be braked through a rod connected at 14, the drive between the sector and members 12, 1 being un-indirectional. The cylinder 5 is pivotally connected at 7 on a crank 17 integral with the sector 12 and may have a permanently open atmosphere adjustable port 18. In the position shown, also the cylinder is freely open to atmosphere through passages 20, 21 in the cylinder and the pivot 7 respectively. There is thus no braking action during the first part of the movement of the sector in the direction of the arrow 16 and during which the piston and cylinder move respectively downwards and upwards. At about the crank position d, the passages 20, 21 are completely out of register and when the crank and piston again reach the positions shown, the cylinder has reached. As uppermost position at which the maximum braking action is this effected. The sector then returns but without, however, turning the crank. The device shown in Fig. 4, may be used in machines for feeding paper or like blanks, for example machines, fitted with conveyer chains carrying gripper bars, the chain s being intermittently stopped.

Filed: 1945-06-07
Abstract: 594,687. Radial pressure clutches. MERCURY CLUTCH CORPORATION. June 7, 1945, No. 14400. Convention date, June 5, 1944. [Class 80(ii)] In a mercury-actuated centrifugal clutch, the expansible mercury containing chamber, which actuates the friction shoes, has a filler ring to divide the chamber into two annular compartments and reduce the quantity of mercury required. The driving discs 13 are splined to a sleeve 6, secured to the driving member 1, and are retained axially by spring rings 14. Flanged clamping rings 15 are mounted on the sleeve 6 and are spaced apart by a sleeve 16, a felt sleeve 17 being interposed as a mercury seal between the sleeve 16 and the clamping rings 15. An annular U-sectioned expansible gland 18 has the inner ends of its legs 18a clamped between the discs 13 and the rings 15, and contains both mercury and an annular filler ring 19 which divides the gland 18 into inner and outer compartments 20, 21. The periphery of the gland 18 bears against the inner support members 26 of the friction shoes 25 which also comprise outer support members 27 and friction members 28. Drive is transmitted to the friction shoes 25 by driver bars 37 located in holes 38 in the discs 13, and the shoes are held out of contact with the driven member 46 by the leaf springs 34. When at rest, the mercury is contained substantially in the inner chamber 20 to the level 24, but when the driving member 1 rotates, the mercury passes by centrifugal action through a clearance 22 between the filler 19 and gland 28, to the outer chamber 21. Increasing speed of rotation causes the mercury to expand gland 18 which acts on the inner support members 27 to engage friction members 25 after the springs 34 have been overcome.
