Abstract

292,770. Abel, J. H. June 18, 1927. Drilling.-A stand or support for a drilling tool of the hand, breast or ratchet type having a stem or stud on which a feeding screw is rotatable comprises a plate F to which are attached two separate chains A, the other ends of the chains being secured, to a nut B mounted on the feed screw C. The chains are attached to the nut B and the plate F by either of the methods shown in Fig. 1 or by providing hooks on the nut, and wire strainers may be incorporated in the chains. A hole S is provided in the plate to allow the drill to pass through and also to act as a drill guide. The plate F may be attached to the work or a bench by screw clamps or may be slidably supported in a guide O, Fig. 5, which may be clamped to the work or a bench either directly or with the interposition of packing blocks. The support may be attached to a girder by the clamp shown in Fig. 7. The Provisional Specification also states that lead or other packing may be inserted between the plate and. the work &c. to prevent slipping. Specification 222,177. is referred to
