Title: Improvements in hydraulic cranes, lifts and other hydraulically actuated devices or apparatus
IPC: B66B1/04
Filed: 1928-10-15
Abstract: 324,093. East Ferry Road Engineering Works Co., Ltd., and Kibbler, H. Oct. 15, 1928. Presses.-Relates to hydraulic cranes, lifts, or other machines provided with means whereby the quantity of fluid is varied substantially in proportion to the load. The main cylinder a communicates with a supplementary cylinder d in which a ram c operates at a lower pressure and actuates the main ram b under light loads, e.g. when raising a crane hook without load. The ram c is operated by high-pressure water acting on an auxiliary ram h in a small cylinder i. The cylinders exhaust to a flooding tank or to a standpipe, and the cylinder d draws water from the tank f or standpipe through a non- return valve g when the ram c falls. Both cylinders i, a are controlled by a shaft n operating the main inlet valve k and the exhaust valves l, m. A valve p between the cylinder i, a is set to open at a given pressure in order to control the operation automatically according to the load. On opening the main inlet valve k full pressure is admitted to the cylinder i and the water in d is placed under low working pressure for raising the ram b, but if the ram b is under load the pressure in the cylinder a acting beneath a piston q opens the valve p and high-pressure water is admitted to the cylinder a. The valve p may be opened proportionately to the load and it may be opened by a tappet r and lever s when the ram c reaches the top of its stroke. The exhaust valve l may be given a lead over the exhaust valve m. allowing the rams c, h to fall to the bottom of their strokes before the main ram b is right down.

Abstract: 924,092. Switchgear structures; oil-break switches; actuation of switches. GENERAL ELECTRIC CO. Ltd. Sept. 17, 1959 [Sept. 17, 1958], No. 29795/58. Class 38 (5).  In switchgear having means for earthing a terminal of a switch by movement of a contact of the switch into engagement with an earthing terminal, interlocking means are provided to permit the use of the earthing terminal as a test terminal after the removal of the earth therefrom, the interlocking means being arranged to prevent movement of the contact whilst the earth connection is removed. Fig. 1 shows one phase of a three-phase switchgear structure for a ring main circuit and having two oil-break switches per phase, the oilbreak switches having moving contacts 17, 17a, each movable from the " on " position shown into an intermediate " off " position and thence into an earth position in which it engages an earthing contact 25 or 25a. The contacts 25 or 25a of the corresponding switches in each phase are earthed by a common earthing blade 43 which is pivoted at 50, Fig. 2, and connected to a push-rod 51. To open the corresponding switches in the three phases an operating handle (not shown) is turned to move a cam member 55, Fig. 3, which stresses a spring 67 and then raises a bar 56 from a detent 57 in a fixed member 58. A member 54 secured to the switch-operating shaft 22 is then turned until the bar 56 engages a detent 60, the contacts 17 being opened. Further operation of the handle causes the movement of the shaft 22 and the member 54 into the position where the contacts 17 engage the earthing contacts 25 and the bar 56 engages a detent 66. In this position, a depression 68 in the cam-like member 54 is over the end of the rod 51 so that the earthing blade 43 may be swung out of engagement with the terminals of the contacts 25, the end of the rod entering the depression 68 and preventing any further movement of the shaft 22 and contacts 17. In Fig. 1, the ring main bus-bar 21 is connected to a tie-off circuit by the isolator 29, fuse assembly 16 and oil-break circuit-breaker 17b described in Specification 29794/58.

Filed: 1920-10-26
Abstract: 170,765. Bailey, N. P., (Hassler, R. H.). Oct. 26, 1920. Spring shackles.-Relates to spring suspensions of the kind in which an auxiliary coiled spring 25 is interposed between the bearing-spring 14 and a lever 18 pivoted to the axle 11 or frame of the vehicle and provided with an extension 21 to limit its movement. According to the invention, the coiled spring 25 is adapted, as shown in Fig. 3, to become compressed into non-yielding form and to take up a substantially vertical position at predetermined heavy loads. The spring 25 is arranged between seats 22, 24 pivotally mounted on the lever 18 and spring 14. and the lever 18 is connected to the spring 14 by shackles 16. When the suspension has reached the position in which the spring 25 becomes non-yielding, further loading causes flexion of the end of the spring 14. When the spring 14 rebounds the extension 21 limits upward movement of the free end of the lever so that the rebound is cushioned by the spring 25 which may again become non- yielding. In the arrangement shown in Fig. 6, the lever 18<1> is pivoted on the frame 31 of the vehicle, and the bearing-spring 14' is secured to the axle 11'.
