time on CABLE CLAMP.

Eat-ented July 14, rear.

Application ales July 2, 1912. Serial in. 707,245.

To all whom "it may concern Be it known that l, FRANK'P. Konan'r, a citizen of the United States, and residingat Fairhaven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Line or Cable Clamps, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to rope, line, or cable clamps, and the object thereof is to provide a clamp particularly adapted for use in connection with wire ropes or cables, but which may, if desired, be used in connection with ropes, lines or cables of any material or class, and which is simple in construction, efiicient in operation and con: venient of manipulation.

The invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the "separate parts of my invention are designated by suitable reference characters in each of the views, and in which Figure 1 is a blank, from which the train part of iny clamp is-formed; Fig. 2 an end view of the clamp complete; Fig. 3 a longitudinal section on the line 3-3 of Fig. 5; Fig. 4 a transverse section on the line 4-4 of Fig.- 3 with the cable removed; Fig. 5 a plan view of the clamp and showing the cable in dotted lines, and; Fig. 6 a view similar to Fig. 3, but showing a modification, and showing the cable in dotted lines.

In the practice of my invention I provide'a clamp device of the class specified-involving in its construction a boxshaped member a formed from a blank a which is preferably approximately rectangular in form and the end portions of which are provided centrally with extensions a The blank a which is composed of steel is drawn, pressed, or stamped into the boxshaped form a comprising a bottom a, side. members a and end portions a having central raised members a formed by the end projections a of the blank, and in this operation the bottom a is crowned or made conc'avo-convex so as to give strength to the boxor box-shaped member a of the clamp.

In the above described operation, the

raisedportions at of the end'members form in connection with the side members a end recesses (t -through which the line, rope, or cable I). or the separate parts therev of, pass, and I also provide a bolt 0 having a transverse head 0 the length of which is approximately the same as the transverse inner dIIIlGIlSlOIlS of the box member a, and

the head 0 of the bolt 6 is provided in the under side thereof with recesses and said bolt 1s threaded, as shown at 0 and is passed downwardly through the box-shaped member a, .or through an aperture 0 formed centrally in the bottom a of said box-shaped member, and said bolt is provided with a nut (13 and washer'd From the foregoing 'description it will be seen that the boX-shaped-member a is open at the top, and in practice the rope, line or cable, or the separate parts thereof are laid therein longitudinally thereof, after which the bolt 0 is assed downwardly through the bottom a o the box-shaped member a with the transverse head 0 thereof resting on and I binding the said rope, line, or cable, and the nut cl is screwed onto said bolt, sufficient force being exerted in this operation to-bend down or compress the rope, line, or cable Z), or the separate parts thereof, as shown in Fig. 3, and securely clamp or hold the same in the box-shapedmember a.

It will be notedthat the bolt head is 10- cated at a considerable distance from the end portions a of the box shaped body and as the recesses formed in said end portions to receive the cable donot extend to the-bottom of thedevice the cable is deflected out' of a straight line by the cl amping portion of head of the bolt. The ends of the clamping head have a guidingengagement with the side members a of the hollow body which prevents the bolt. from'turning, thus holding it in properrelation with the portions of the cable and also facilitating the turning up of the nut.

It. will also be seen that my invention involves only two parts, the box-shaped member a and the bolt 0 having "the transverse head 0 said parts being constructed as shown and described, the bolt d and washer d being common devices of their class.

. In Fig. 6,1 have shown a modification in which the box shaped member ais elongated and two of the bolts 0 employed, and in this form of construction the box-shaped member a is provided with a transverse raised bar or similar device 6 which is secured therein and to the bottom a of said box-shaped member and over vwhich the rope, line, or cable, or the separate parts thereof, are passed. It will be understood that this form of clamp is employed where greater strength is required, and by means of myimprovement I provide a clam device of the class described possessing the greatest possible strength in proportion to the material employed, and which, while answering all the requirementsof a clamp of this class, can be made at a minimum cost and applied and used in the simplest and most efi'ectivemanner. I

Having fully described my invention what I claim as new and desire to secure by Letters Patent is 1. In a clamp of the class described, a hollow body formed of thin metal and having a bottom and struck-up lateral and end Walls forming reinforcements for the bottom and stiflening the hollow body longitudinally and transversely, the end walls being provided with recesses of less depth than said walls, a clamping boltextending' through the bottom plate at a considerable distance from both the recessed end walls and having a head disposed transversely of the body and lying within the'lateral walls, and at a considerable distance from each end wall, whereby said head will engage the strands of a cable and deflect them out of a straight, line, and the recesses in' the end walls will hold the cable strands against lateral displacement.

2.111 a clamp of the class described, a hollow body formed of thin metal and having'a bottom, and lateral and end Walls, the end Walls being provided with recesses of less depth than said walls, said body havin its greatest length between said recessed walls and a clamping bolt extending through the bottom. plate, at a considerable distance from both. the recessed end walls,

and having a head disposed transversely of the body, and lying within the lateral walls, the end faces of said head engaging the inner faces of the said lateral Walls to prevent the rotation of the bolt with respect to the saidbody, and a nut on said bolt whereby said head Will engage'the strands of a cable at a considerable distance from. the points of engagement of the end walls therewith, and deflect the same toward the bottom of said hollow body.

3. In a clamp for rope or cable, the comv bination with a hollow body having a bottom and side and end portions, the end portions being provided with recesses of less depth than said end portions, said bottom being provided with a central transverse raised portion, of a bolt passing through said bottom. on each side of said raised portion, and located at a distance therefrom and from the adjacent end portion, said bolts having clamping heads extending transversely of the hollow body, and having fiat end portions in guiding engagement with the side portions of said hollow body,

and nuts on said bolts whereby the heads of said bolts will engage the cable strands at considerable distances from said end portions, and from said centrally transverse raised portion, and'will readily deflect them toward the bottom of said hollow body.

In testimony that I claim, the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 28th day of June 1912.
