Title: Improvements in and relating to lifting jacks and the like
IPC: B66F1/02
Filed: 1945-05-29
Abstract: 606,344. Load-handling apparatus; lifting jacks. BRADBURY & SONS, Ltd., J., and FORSTER, F. May 29, 1945, No. 13478. [Class 78 (iii)] [Also in Group X] Relates to working platforms for scaffolding, and is a development of the invention described in Specification 591,596, [Group X], whereby the rate of descent of the guide can be controlled, from the platform attached thereto, by frictional means. In the Figure is shown the slide 21, from which the guide (not shown) is suspended, the operating lever 22, the links 25 and the gripping plate 24, all as designated in Specification 591,596. A friction shoe b is pivotally attached to the lever 22 at d so as to make contact with the standard 5 when the lever is near the limit of its upstroke. A rocking trigger f is mounted on an extension of the lever 22 with a bit g which can engage with a projection 24<1> on the gripping plate 24. When the'hand-grip h of the trigger is pressed towards the lever, against the pressure of the blade i, the gripping plate 24 is tilted to its neutral position by the bit g, but only after the lever 22 has been brought near enough to the limit of its upstroke for the friction shoe b to have been associated with the standard. The bottom gripping plate can be freed as described in Specification 591,596. The guide can then descend the standard, the rate of descent being controlled by altering the pressure of the friction shoe through the operating lever. Should the operator lower the lever sufficiently to bring the shoe away from the standard he will at the same time remove the bit g from the projection 24<1> of the plate a distance sufficient to enable a spring or the like (not shown) to move the plate to the gripping position, and descent will therefore be stopped. The lever 22 may be loaded by a spring so that it occupies the braking position. A second shoe may be provided, pivoted to an extension of the lever beyond the pivot 22<1>, so that the two shoes grip the standard between them when the lever is in its uppermost position.
