GUY-STRAND CLAMP.

Specification of Letters Patent.

Patented Aug. 13, 1918.

Application filed December 1, 1916. Serial No. 134,496.

To all whom it may concern:

Be it known that I, BERTON M. MATHIAS, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State. of Minnesota, have invented certain new and useful Improvements in Guy-Strand Clamps, of which the following is a specification.

One object of my invention is to provide in a guy strand clamp, means for preventing the loop and the guy strand from spreading at the clamp itself.

Another object of my invention is to provide in a'strand clam'p, means for creating a stronger grip on the dead end of the strand than on the live end.

Another object of my invention is to provide means for maintaining the stress on the bolts in an axial direction and thus preventing the bolts from bending.

With these and incidental objects in view, the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms a part of this specification.

In the drawing, Figure 1 is a side elevation of my preferred construction as applied to a looped strand. Fig. 2 is a section taken on the line A A Fig. 1, and Fig. 3 shows a modified section on the same line A A as an alternate construction.

Fig. 4 discloses an alternate construction of the retainer, and Fig. 5 still further alternate construction.

Fig. 6 is a modified form of clamp using straight bolts instead of U bolts; Fig. 7 is a section taken on the line B B Fig. 6; and Fig. 8 is a section taken on the line C C Fig. 6.

Fig. 9 is an end view of the clamp shown in Fig. 1 as viewed from the direction of the arrow I); Fig. 10 is a section taken on the line E E Fig. 9; and Fig. 11 is an enlarged detail of a preferred form of washer.

The prime object of my invention is to combine with a clamp a retainer. In my preferred construction, I employ a body member 1, having formed at one end thereof, a loop or retainer 2 having the opening 3, Fig. 2, sufiicient to easily pass therethrough the ends of the guy strand 4:. i

The end 5 of the guy strand takes th strain for which the strand is used, and the large loop 6 is passed around a pole or stub which tends to spread the strand apart at 7 were it not for retainer 2.

The dead end of the strand 8 is passed through the clamp proper at 9, and this clamp may comprise a .U bolt or clamping members of any other suitable style of uniting clamp members on the guy strand.

As shown in Fig. 1, the inner grooved surface of the body 1 is corrugated at 10 as the dead end of the strand has more tendency to slip from the clamp than the strain end of the strand.

Instead of having the retainer 2 formed in a letter 0 style, I may form it in a C shape as shown in Fig. 3 so as to allow the strands to be slipped through the opening of the C instead of threaded through as necessary with the O shaped retainer; or I may have the retainer in the form of'a separate part 11, Fig. 4, butting on the end 12 of the body member 2, the end 12 being preferably formed at an angle as shOWn to better position the retainer for the strains set up by the loop.

In Fig. 5, I show a construction wherein the retainer 2 is replaced by a U shaped member 13, fastened to the body 2 by a bolt or pin 14.

For some classes of work, the body member is better formed as at 15, Fig. 6, terminating in one end in the retainer 2 and coacting with a plate 16 by means of bolts 17 Where the guy strands are small and it is diflicult to work the nuts on the U bolt used in Fig. 1, I find it advantageous to form this U bolt with a substantially oval cross-section as shown in Fig. 10, thereby spacing the center lines of the bolt farther apart without modifying the fitting of the U bolt with the small guy strand. 7

With any of the constructions shown, I may use as an addition to the nuts on the bolts, a rocking washer 18 and form the body 2 with a depression 19 registering with the rocking washer so as to insure the strain always coming evenly on the bolt. With this construction, even though the U bolt or straight bolt, whichever the case may be, is drawn out of line by the guy strand, the strain in the bolt itself will be in an axial direction, and hence the bolt will not bend under the strain.

While I have described my invention and illustrated it in several designs, I do not wish it understood that I limit myself to these constructions, as the application in my invention may be varied in many ways within the scope of the following claims:

Claims 1. In a guy strand clamp, the combination of clamping means, a retainer spaced from said clampmg means, to prevent spreading of the guy strand passing therethrough, a bolt, nut and washer forming a part of said clamping means, said washer having a curved projection thereon to register with a co-acting depression in said clamping means for the purpose of maintaining tension set up in said bolt in an axial direction.

2. In a guy strand the combination of a body member, a U bolt co-acting therewith to form therewith clamping means, said U bolt havin an ovoid cross-section at its U shaped en and retaining means associated with said body, spaced from said U bolt to prevent spreading of strands passing therethrough.

3. In a guy strand clamp the combination of a non-clamping body member, clamping means carried at one end of said body member, and a non-clamping retainer of a C shape carried at the other end of said body member to retain therein two guy strands, thereby preventing the spreading of said strands at said clamping means.
