Description

June 14, 1949. c. R. PI PER 2,473,071
CABLE CLAMPING DEVICE Filed July 9, 1947 I INVENTOR; CHESTER R.P/EPER ATTORNEY Patented June 14, 1949 UNITED STATES PATENT QFFICE- 3 Claims.
This invention relates to cable fasteners generally, and has particular reference to an im proved clamping device especially adapted for securing a guy cable to the rod of a land anchor.
Among the objects of the present invention are: to provide an anchor rod having self-contained fastening means for the guy cable; to prevent injury to the cable where the same is connected to the rod; to facilitate the application and securement of the cable to the rod; to eliminate the need for cutting the cable prior to its application to the rod, and to secure the cable in substantial alignment with the rod to reduce bending stresses therein.
These and other objects and advantages will appear from the following description wherein reference is made to the accompanying drawing showing the improved clamping device of my invention. In this drawing:
Fig. 1 is a top plan view of the clamp body;
Fig. 2 is a front elevational view of the clamp body;
Fig. 3, a front elevational view, shows the entire clamp structure with a cable secured thereto;
Fig. 4 is a side elevational view of the clamp e body, and
Fig. 5 is a transverse sectional view taken at line 55 of Fig. 4.
Referring now by characters of reference to the drawing, numeral designates the upper end portion of a metal rod which may, as contemplated herein, constitute the stem of an earth or land anchor used for staying guy cables and the like. One end of the rod, for convenience referred to as the upper end, is upset and flattened by forg ing processes to produce thereon an enlarged, generally discoidal body I l, the plane of the body being canted at a small angle to the rod as shown in Fig. 4. The rod joins the sloping back side of the body, leaving the front and marginal portions of the body unobstructed.
The body is constructed somewhat in the form of a pulley or sheave in that it is provided with a peripheral groove I2 defined between marginal flanges l3, to provide a circumferential cable-receiving seat. The body is further characterized by a cable-receiving groove or channel l4 that extends diametrically of the body in alignment with the rod In, the channel having a gradually widening throat at its lower end, opening in the lower edge of the body in front of the neck portion I 6 of the rod. It will be observed that the diametrical groove I4 is relatively shallow at its upper end and does not, at this end, penetrate or transect the peripheral groove l 2, so that cable portions seated in and extending through the diametral groove do not interfere with a cable portion lying in the peripheral groove.
The diametrical groove M is of gradually increasing depth and the curved, divergent side walls ll of the throat merge with the bottom surfaces of the peripheral groove as shown. A centrally located longitudinal rib l8 rising from the bottom of the diametrical groove divides the same and forms a pair of laterally adjacent cable seats l9 and 20. The paired seats l9 and 20 are flanked by two pairs of apertures M which accommodate the legs of U-bolts 22, nuts 23 being threaded on the legs of said bolt at the back side of the body.
Securement of a guy cable under tension to the described clamping structure may be easily accomplished. First the U-bolts '22 are removed, whereafter the cable is laid in one of the diametral wire seats and looped about one of the curved surfaces or cheeks H1. The free end of the cable is drawn tightly about the said cheek until the desired cable tension is attained, and then is wrapped completely around the body in the peripheral groove and placed in the diametrical groove adjacent the companion cable portion. The U-bolts are reapplied to the body and clamped tightly upon the paired cable portions, as shown in Fig. 3.
The peripheral cable seat contacts the cable in an arc of approximately 540 degrees and afiords excellent frictional snubbing effect thereon. The cable portions entering and leaving the clamp body are parallel with each other, which affords an ideal condition for clamping b means of the U-bolts 22.
I claim:
1. A rod having means for securing a cable thereto, said means comprising a discoidal body formed on said rod with the plane of said body disposed at an angle to the axis of said rod, said body having a diametrical cable-receiving channel in alignment with the rod and a peripheral cable-receiving channel communicating with the lower end of said diametrical channel, and cable clamping means extending transversely of said diametrical channel.
2. A rod having means for securing a cable thereto, said means comprising an enlarged head portion formed on said rod, said head portion having a cable-receiving channel extending in substantial alignment with the rod axis, and a peripheral cable receiving channel extending around the head portion in a plane disposed at an angle to the rod axis and communicating with 3 the lower end of the first said channel, and cable clamping means extending across the first said channel.
3. A rod and means for securing a cable thereto, comprising a discoidal body integral with the rod, said body having a continuous cable-receiving groove having a first portion extending across a side face of the body in alignment with the rod, a second portion extending in a circumferential path'iatfithe'puterredge of the body and a third portion' extending .acrossthe said side" face of the body in parallel adjacence to the first said portion, the circumferential portion of said groove being in a plane at an angle to the first and third portions; openings extending through'the'body 15 "23031303 4 and U-clamps extending through said openings for securing cable portions disposed in the first and third portions of the said groove.
CHESTER R. PIEPER.
