ABSTRACT:
A clamping device particularly suited for clamping the rails of an elevator to the frame of a building. Such elevator rails are usually T-shaped in section, having the base fastened to fastening elements or brackets on the frame and the vertical portion extending therefrom. Clamps are used to fasten the base of these rails to the brackets on the building. The clamp here described has a flat base with two spaced longitudinal flanges and a hole in the base for the reception of a bolt. The longitudinal flanges are partially cut out along their bottom edges and there is a lateral flange extending between them immediately behind the cut out portions. The cut out portions are shaped to fit on the base of the rail. The longitudinal flanges contact two flat sides of the head of a fastening bolt, which may be inserted in holes in the clamp and bracket. A nut on the bolt is tightened by the use of one wrench for the bolt is held from rotation.
