Title: Improvements in or relating to machines for forging metal rings
Inventor: BAKER SYDNEY ERNEST
IPC: B21K1/04
Filed: 1961-05-18
Abstract: 1,031,672. Forging rings. WOODHOUSE & RIXSON Ltd., and S. E. BAKER. Aug. 17, 1962 [May 18, 1961], Nos. 31744/62 and 31745/62. Divided out of 1,031,671. Heading B3H. A machine for forging metal rings 16 comprises a bedplate 1 carrying a radial forging tool 15 and an axial forging tool 17, means 8 for rotating the ring between forging strokes including a pair of rolls 8 which bear upon the periphery of the ring and are movable parallel to the bedplate 1, and means 23, Fig. 3, for controlling the forging operation in dependence upon the position of the rolls. Both tools 15, 17 are actuated by hydraulic rams 3, 4; the tool 17 is pivoted at 18 on an adjustable fulcrum. Rolls 8 are carried on arms 9 pivoted at 11 and connected by links 12 to a ram 13 working in an hydraulic cylinder 14. One arm 9 is connected to a link 23 operating a cam 24, Fig. 3, engaged by a bell-crank 25 controlling an air bleed 27 in an air line 29. Pressure in the latter controls a spring - loaded piston 30 connected to a pinion 33 controlling the delivery of a variable stroke pump 34 which supplies a main hydraulic pump 36 feeding the rams 3, 4. Both pumps are driven by a cam 35. As forging proceeds the tools 15, 17 are gradually advanced by extra liquid being supplied by pump 34 to pump 36. The diameter of ring 16 thereby increases which forces the rolls 8 outwards and this tends to restrict bleed 27 which reduces the delivery of pump 34 and hence slows down the rate of forging. Finally a limit switch stops pump 36. In another embodiment, Figs. 4, 5 (not shown), a vertical machine of the kind described in Specification 1031671 is used. The tools may alternatively be driven by cranks whose stroke length is determined by screws operated by an hydraulic motor supplied from a variable stroke swash plate pump controlled by the piston 30. Reference has been directed by the Comptroller to specification 859,791.

Abstract: 210,406. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Kasley, A. T.). Jan. 26, 1923, [Convention date]. Adjusting and connecting bogies for steering. - Two axletrucks are connected by a link or draw-bar preventing longitudinal movement of one truck relatively to the other and a coupling connecting diagonally disposed comers of adjacent ends of the trucks which is substantially rigid under predetermined loads but yieldable under excess loads. The trucks 10, 11 are connected by a rigid draw-bar 22 and the sole bars 22<1>, 23 are each extended to form an anchorage for a forked rod 28 which carries the spring 37 between follower plates 33, 34. A bar 35. which may be forked, passes through the follower plates and is provided with a distance sleeve 42 for limiting the compression of the springs. The end of the rod 35 is pivoted to a link 47 which has its opposite end pivoted to the framework of the axle-truck. Both spring systems are connected by a two part riveted link 27 the rivets of which are adapted to shear when the springs 37 are so compressed that the distance sleeve 42 abuts both follower plates 33, 34. The springs 37 are initially compressed so that when the trucks travel on a track of normal curvature the transverse link mechanism acts as a rigid connection and exerts a guiding action on the trucks. On a track of abnormal curvature the springs are compressed either by the follower plate 33 or 34 according to whether the ends 22<1>, 23 move toward or away from one another. In the case of extreme movement of the ends 22<1>, 23 due, for example, to a derailment, the rivets in the member 27 will fail by shear
