Title: Improvements in or relating to Safety Guards.
Inventor: MATTHEWS LEONARD FREDERICK
IPC: F16P3/00
Filed: 1966-05-11
Abstract: 1,180,051. Machinery guards. G. A. HARVEY & CO. (LONDON) Ltd. 11 May, 1967 [11 May, 1966], No. 20956/66. Heading F2J. A safety guard 28 protecting the working zone of a machine tool is moved bodily by the machine during its operating cycle between a first position preventing access to the working zone and a second position allowing limited access for feeding, bending, or removing workpieces, and is rotatable manually between the first position and a third, fully open position when the machine is inoperative. The guard and a pedaloperated linkage (12) (Figs. 1, 2, not shown) controlling the machine driving clutch (13) are interlocked to prevent simultaneous full opening of the guard and operation of the clutch. The guard 28 comprises a perforated screen depending from an angle section beam 27 having stub axles 26 secured to it and projecting from its ends to bear in vertical slots 25 in plates 24 bolted to fixed posts 20 and vertically adjustable thereon. The guard is so balanced that it tends to rotate inwardly into the working zone. In its closed position, the axles 26 rest in the bottoms of slots 25 and an arm 50 secured to one axle 26 rests against an adjustable stop 51 to hold the screen away from the working zone. In operation, when a platen (14), (Fig. 2, not shown) approaches an anvil 15, strikers 33a on the platen contact the ends 32 of respective levers 30 having fixed pivots to act via links 29 to raise the axles 26 in their slots so that the guard pivots slightly and assumes its second position, shown chain-dotted in Fig. 7, in which a workpiece 53 can be bent and removed. One end of an adjustable-length push-rod 37 is spring-urged against a cam 34 secured on the axle 26. An axially movable rod in the clutch actuating linkage (12) carries a stop 43 and a socket 44. With the guard in its first or second positions, a flat on the cam allows the other end 47 of the rod 37 to remain clear of the stop 43 and socket 44. If the clutch control is not actuated, the guard may be pivoted outwards to its third position, the cam moving the rod 37 into the socket 44 to lock the clutch control. If the clutch control has been actuated, the stop 43 is aligned with the rod 37 and prevents rotation of the guard into its fully open position. In a modification (Fig. 8, not shown) for a machine having a pneumatically actuated clutch with push-button control, a cam on the screen axle closes a valve in the pneumatic circuit when the screen is pivoted through a predetermined angle towards its open position, to stop the machine.

IPC: B62D11/12
Filed: 1961-06-12
Abstract: 985,283. Change -  speed gear. P. P. RICHARD. June 12. 1961 [Aug. 12, 1960], No. 21116/61. Heading F2D. [Also in Division B7] A track-laying vehicle comprises an engine including a super-charger driven by a differential inserted between the engine output shaft and the load, a transmission line between the engine and each of two tracks, and two changespeed gears, one in each transmission line, the gears being individually operable to effect steering of the vehicle. In the Figure, the output shaft 2 of a diesel engine 1 drives the planet carrier 3 of epicyclic gearing, the sun wheel of which drives a supercharger 9 through gears 7, 8. The ring gear 4 is connected to an output shaft 5 which drives endless track sprocket wheels or the like 21, 22, through identical transmissions each comprising a gear 11 or 12, change-speed gear 13 or 14, and bevel gears 17 and 18, or 19 and 20. Driving the supercharger through an epicyolic differential gear permits the engine to develop full power while the speed of shaft 5 varies by a factor of about two and a half, the actual speed of the shaft depending on the load. The change-speed gears 13, 14, are thus required to vary the speed of drive by a factor of about 1À6, to give a final drive speed which can vary by a factor of four. Steering is effeeted by actuating one only of the change-speed gears, so that the intended inner track is driven at a lower speed than the intended outer track. In another embodiment, the gears 11, 12 drive pumps feeding hydraulic motors which drive the endless tracks. Each pump drives two motors, both motors driving the same track, and fluid may be pumped to one or the other or both motors to change the drive speed. The motors may be of different maximum power. Alternatively, each gear 11, 12 may drive two pumps one, or the other, or both of which may be selected to drive a single motor. In an electric transmission, electric generators and motors may replace the hydraulic pumps and motors, and two generators or motors may be connectable in series or in parallel.
