CABLE-GRIP.
Specification of Letters Patent. 7
Patented Sept. let, 1915.
Application filed March 18, 1309. Serial N 0. 484,107.
To all whom it may concern:
Be it known that 1, WILLIAM HUTCHINGS, acitizen of the United States, residing at Eveleth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Cable-Grips, of which the following is a specification.
My invention relates to an improvement in cable grips, and the object is to provide means whereby the end of the cable can be grasped and drawn through conduits or over the cros-bars of telephone telegraph or electric lighting poles.
The invention consists of certain novel features of construction and combinations of parts, which will be hereinafter described and pointed out in the claim.
In the accompanying drawingsFigure 1 is a vertical sectional view; Fig. 2 is a sectional View of the tube member with the gripping members removed; Fig. 3 is a view in front elevation of one of the gripping members; Fig. fl: is a rear view of one of the members; and Fig. 5 is a view in elevation of the clevis and its connecting members; Fig. 6 is a transverse sectional view showing the tube with the gripping members therein.
A represents the tube member, which is constricted at its lower end as at 1. The lower end of the tube being beveled as at 2 on its inner surface. Grooves 3 are formed at equidistant intervals in the beveled portion, which grooves taper downwardly toward the lower end of the tube. The gripping members 5 are preferably made in three pieces, as shown in Fig. 6, and each piece is provided with a lug A, which is adapted to be received in the groove 3 in the tube A, permitting the members to slide in the tube and the lugs retaining the members in their proper positions against turning. The purpose of the taper in the grooves 3 and on the lugs A is to prevent the pieces 5 from falling out and becoming lost should the springs 6 break or become dislodged. Encircling the members are springs 6, which enter grooves 7. The springs hold the members together and allow a certain amount of expansion of the members before they are drawn down to the lower part of the tube where they are drawn close together by the beveled formation of the tube. Within the bores of the members are formed teeth 8, which preferably extend transversely. These teeth are adapted to engage the cable and hold it securely as it is being drawn either 7 the tube.
through a conduit or over the cross-bars of a pole.
The upper end of the tube A is screwthreaded as at 9, and received in the tube is a hollow plug 10, which is screw-threaded on its exterior as at 11, which screw-threads are adapted to engage the screw-threads of Notches 12 are formed in the surface of the plug 10, to receive a tool for screwing the plug into the tube A. The plug is internally screw-threaded for a short distance, and a collar 13, which is also screwthreaded, screws into these threads as at 14. The upper end of the collar flares outwardly as at 15, and is swiveled between the flared portion and the plug or clevis 16. A lead cable, or for that matter, any other cable may be inserted into the tube A, forced therethrough out through the collar 13. As the strain is placed upon the clevis 16 the gripping members 5 will be drawn toward the end of the tube and the beveled surface of the tube will cause the gripping members to grasp the cable and consequently the greater the pulling strain upon the clevis, the tighter the members will grip the cable. By providing an opening entirely through the device, there is no danger of the cable pulling out of the tube member before the jaws or gripping members will have an opportunity to properly grasp and hold the cable, for the reason that when inserting the cable in the device it will be forced entirely through the collar 13, and as the strain or pulling action from the clevis will cause the jaws or members 5 to slide along the beveled surface of the tube member A and grip the cable, and after the teeth on the members 5 have gripped the cable there will be no danger of the cable becoming disengaged from the tube member.
It is evident that more or less slight changes might be resorted to in the form and arrangement of the several parts described within the scope of the claim, and hence. I do not wish to be limited to the exact construction herein set forth, but
Having fully described my invention, what I claim as new and desire to secure by Let ters Patent, is:
A cable grip comprising a tube having an internally beveled or constricted lower end, with vertical grooves formed at intervals in the beveled or constricted end, a plurality of gripping members having internal teeth and tapering beveled lower ends, said ends adapted to restuponthe constricted end of the tube in order to frictionally force said members together at the bottom, the inner diameter of the gripping members When con to in the grooves in the tube and prevent the Copies of this patent may be obtained for five cents each, byaddressing' the F Commissioner of Patents,
members from rotating, and means to sustain the pulling strain secured at the upper end of the tube for confining the gripping members therein;
In testimony whereof I aflix my signature, in the presence of two Witnesses.
