Filed: 1942-05-14
Abstract: 555,661. Internally-expanding brakes. PRATT, J. H., and GIRLING, A. H. G. May 14, 1942, No. 6559. [Class 103 (i)] An adjusting device for internally-expanding brakes comprises a spindle 7 which is turned by its hexagonal projecting end, so that the engagement of the corners of its hexagonal or like central part with the flat inner faces of sleeve members 9 and 10 causes a displacement of the members and through struts 13 of the shoes. Further turning of the spindle 7 causes through rotation of pinion 8b having teeth 8a engaging teeth on the ends of sleeves 9 and 10 a rotation of such sleeves which by screw threads 10 also cause an outward movement of plugs 11 and 12 to spread the shoes by struts 13. Rotation of the spindle 7 is continued until the shoes engage the drum. The spindle 7 is then turned in the reverse direction to bring the sleeve members 9 and 10 back into engagement with flats on the central part of the spindle thus resetting the brake clearance which is fixed by the size or depth of such flats.

Abstract: 897,113. Ammunition fuzes. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Feb. 25, 1960, No. 6591/60. Class 9(1). A percussion fuze, more particularly for unrotated projectiles, which can be arranged to operate instantaneously on impact or after a delay, has a casing 1 with an axial passage containing a relay train 26 aligned with a booster 10 and a firing pin 4 carried by a cap 3 slidable in the fuze head 2. A hood 6 of resilient plastic material covers the cap. The pin 4 extends into an opening in a switch 31 and is aligned with a blind bore 14 in a transverse slide 9 during transport. By rotating the member 31 through 90 degrees from the position of Fig. 1, the pin 4 is rendered inoperative and the fuze set for delayed action by a firing pin 28, Fig. 5. After firing the projectile, a detent 18 and a surrounding sleeve 16 set back due to inertia and release the slide 9. The slide, thrust by a spring 15, then moves across the fuze, its movement being braked by a rack 22 and pinion 23 controlled by an escapement 25, until a bore containing a detonator 11 is aligned with the pin 4 and the train 26. The fuze is then ready for operation on impact if the switch 31 is correctly set. With the switch set for delayed operation, after impact, sleeves 37, 41 co-operating with balls 40 to lock the pin 28, Fig. 5, are forced apart, the forward sleeve entering a bore 12 in the slide 9. A spring 39 then drives the striker 28 against a detonator 13, which by way of a groove 7a, fires the detonator 11 and the train 28 as before.

A fluid-actuated clamp for clamping a workpiece F, Fig. 1, against a support K comprises a piston 17, Fig. 2, reciprocable in a cylinder 14 by pressure-fluid applied to a chamber 33 and acting .against a spring 29, a stud 10 attached to the support, e.g. by screw threads 11, and means, e.g. balls 30, operable by movement of the piston towards the work to anchor the cylinder to the stud, whereby the piston can press the work against the support. The cylinder contains a sleeve 22 which engages the end of the stud, the balls being contained in radial holes 31 therein'and moved into a groove 32 in the stud by an extension 18 of the piston which slides over the sleeve. A recess 26a in the end of the extension allows outward movement of the balls to release the stud when pressure, is released from chamber 33 and the piston is withdrawn from the work by spring 29. As shown, the support is a jig receiving the reduced end of cylindrical work which is to have a number of radial holes I drilled therein, the work being indexed by table A, rotated step-bystep by a compressed-air mechanism. To permit cylinder 14 to turn with the work, fluid, e.g. compressed air, is supplied to and exhausted from chamber 33 via member 38 within the sleeve 22, and connected to line 36. In another arrangement, where large work is to be clamped, a number of clamps are provided at the required positions and fed from a common source. Where the air-pressure available is insufficient, it may be applied to a piston which moves a smaller piston in cylinder containing hydraulic fluid, the resulting pressure of which is thus greater than that of the air supply. In a modification the stud has a T-head for engagement with a slot in a-work-supporting table, and threads at its free end for engagement with threads in the sleeve of the clamp.
