Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed February 28, 1907. Serial No. 359,808.

' ticularly to rope clamps or guy clamps, and

the objects of the invention are to improve upon the construction of such devices, and increase their efficiency of operation, with simplicity of parts, which are cheap to manufacture.

Another object of the invention is to enable the ropes to be more securely clamp-d between the parts than heretofore.

Further objects of the invention will hereinafter appear, and to these ends the invention consists of aguy clamp for carrying out all of the above objects embodying the features of construction, combination of elements, and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification, and shown in the accompanying drawings in which Figure 1: is a side elevation of the clamp embodying the invention; Fig. 2 is a vertical section of the same, on the line :z-a; of Fig. 1

Fig. 3 is a side elevation of a modification of the guy clamp, and Fig. 4 is a vertical section on the line y-' of Fig. 3.

According to this invention the guy clamp comprises three parts, a body member or jaw A, a securing memberjor bolt B, and a nut C or C. The body member or jaw A is preferably provided with flat parallel faces D and E, and a single central longitudinal hole F entirely surrounded by the material of the jaw A. One of the faces of said jaw A is provided with transverse grooves G at each side of the central hole F for the reception of the ropes H to be clamped.

Either the bolt B or nut C is provided with transverse grooves J adapted to register with the grooves G and cooperate therewith to clamp the ropes H.

In Figs. 1 and 2 the flat head K of the bolt is provided with grooves J on its under side and the screw-tlreaded shank L of the bolt is adapted tobe passed through the central jaw. It will be seen that the under side of the bolt head is adapted to lie in proximity to the jaw without touching the same. Preferably, both sets of grooves G and J both in Fig. 1 and in the modification in Fig. 3. are

curved as shown more particularly in the sectional views. 'Preferably these grooves G and J are curved in planes lying substantially parallel to the axis of the shank of the bolt, in this instance the grooves J being concave, while the grooves G are convex. According to this construction, the ropes are clamped more firmly. in position than if the grooves were straight.

In Fig. 3 the shank L ofthe bolt is adapted to be inserted through the aperture F from the opposite side of the jaw A to that in which it is inserted in Fig. 1, so that the head K of the bolt lies against the jaw. The nut C in this instance is provided with the grooves J which cooperate with the grooves G of the jaw A.

I am not to be understood as limiting the invention to the formsof guy clamps shown, for the device may be embodied in widely varying forms within-the scope of the apended claims. The invention contemplates, owever, a simple form of guy clamp comprising three essential arts, whereby the guy ropes may be clamper directly between and against any two of said parts.

I claim and desire to obtain by Letters Patent the following:

1. A guy clamp comprising in combination 'with cooperating curved transverse grooves adapted to lie at each side of the shank ofthe bolt, whereby guy ropes may be clamped directly between said two grooved parts.

2. A guy clamp comprising in combination three parts only, first, a body member or jaw having fiat parallel faces, and a single central longitudinal hole entirely surrounded by the material of the jaw, one of theta-cos of said jaw being provided with curved transverse grooves at each sideof the central hole, secondly, a securing member or bolt having a 5 the jaw, the under side of the olt head beingfiat head, a shank a screw -threaded end, against the bolt head and jaw, and thirdly,'

" the shank ofthejbplt being passed Kthrhugh -& nut on the screw-threaded shank ofuthe the central hole in the jaw, and theheadof bolt for tightening and holding the parts.

the bolt lying opposite the rooved fece of 'In testlmony whereof I have signed this specification in the presence of two subscriblng wltnesses.
