CLAMP.
SPECIFICATION forming part of Letters Patent No. 761,282, dated May 31, 1904.
Application filed ember 14, 1903.
To all whom it may concern:
be operated on by a punching and shearing machine, or the clamp can be used equally as well in building and other construction work where it is necessary toelevate metal plates, platforms, at. i
My invention consists of the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying rawings, in which Figure 1 is a perspective View of my clamp in use. Fig. 2 is a side elevation of the clamp in use. Fig. 3 is an end View of the clamp, the eccentric lever being. shown in a vertical In the drawings, A represents a metal plate to be lifted by my clamp. In constructing the clamp I employ a lever B, perforated adjacent one end, as shown at B, and the oppoand slightly enlarged, as shown at B 1 The hook 'member C comprises the straight flat face 0, which is adaptedto engage'the under face ofthe plate to be lifted. Extending upward from the rear end of the lower horizontal memberof the hook on which the face 0 is formed are two parallel arms 0 These arms are slightly spaced apart and in their lower portions are arranged at a right angle to the face 0 and are then bent forward over the horizontal member. The lever B fits between these arms, and the upper forward portion of the arms is pivoted by a suitable bolt to the lever adjacent the rounded head B A chain D has a link secured in the' perforation B of the lever B.
Serial 110,177,037. (N0 model.)
the chain D being connected at one end to the lever of one clamp and at the opposite end to the lever of the other clamp, and the central part of the chain is engaged by the hook of the hoisting -chain. (Not shown.) When the clamps are placed in the position shown in Fig. 2, it will be obvious that an upward pull on the ohainD will tend to lift that end of the lever and that the end B will be forced downward, bearing on the plate A, which will be held firmly between the end B and the face C of the hook.
These clamps will not only hold a plate in a horizontal position, but also at any angle that may be desired. I
Having fully described my invention, what I desire to secure by Letters Patent and claim as new is 1. A hook member having parallel, upwardly and forwardly extending arms spaced apart and a straight, fiat face formed inadmeans for lifting the opposite end of the lever.
3. A'device of the kind described comprising a member having a straighfi'face, parallel arms extending upwardly from and at right angles to said face and having their upper portions curved over the face, and a lever having a rounded enlarged end fitting between and pivotally connected to the arms.
4. A clamp of the kind described comprising a lever perforated adjacent one end and enlarged and rounded at theopposite end, a hook member pivoted to the lever adjacent the enlarged end and having a flat face adapted to lie substantially parallel with the lever, and a chain having one end attached to the perforated end of the lever, substantially as and for the purpose described.
