Abstract

410,565. Wedges. WOOD & CO., Ltd., H., Sun Buildings, Collingwood Street, BRITTON, W., 2, Brompton Terrace, Whickham, both in Newcastle-on-Tyne, and HAYES, A., 10, Aintree Gardens, Gateshead, Co. Durham. Jan. 19, 1933, No. 1803. [Class 89 (ii).] A wedge chock comprises opposed longitudinal members 1 each provided with wedge-pieces 2 at each end, longitudinally moving wedge portions 5 to coact with the wedge-pieces, and releasable means 6 to cause movement of the longitudinally moving wedges. Intermediate coacting wedge portions 7 and 8 may be provided on the opposed members 1 and wedges 5, respectively, to give further support to the central part of the chock and for this purpose also the transversely-moving actuating-wedge 6 may have vertical wedge-ribs 10 to coact with transverse wedge-ribs 9 on the outer members. As shown, the releasable means comprises a wedge 6 with ribs 6<a>, 6b, Fig. 5, to prevent detachment, and double inclined wedge surfaces 6<c>, 6d for quick and slow adjustment. The outer members are provided with slotted links 3 for loose attachment. The central actuating wedge may be replaced by toggle-levers or by a reverse-screwed shaft.
