Abstract

386,116. Wedges. KIMMINS, E. J., Cotswold Grange, Stonehouse, Gloucestershire. Jan. 5, 1932, Nos. 249 and 6761. [Class 89 (ii).] Shores or chocks of the type comprising a plurality of members having inclined contacting surfaces gapped to receive a transverse wedge to cause relative movement of the members have at least two of the members formed of a plurality of timbers with inclined edges spaced apart and a double coacting wedge member. The lower member in the example shown is formed of superposed timbers a, b, and wedge members c connected by cross members. The intermediate member may also be formed of superposed timbers or alternatively formed ot end wedge members connected by cross members h. The upper member is formed of superposed timbers k connected by bolts l. The wedge members have gapped coacting faces and are metal surfaced. The wedge p is formed with spaced wedge members q and end projections to receive hammer blows. Guide members may be used on the coacting wedge members.
