Joseph F. Topinka, Cleveland, Ohio Application March 13, 1943, Serial No. 479,138
2 Claims. 1 (01. 24-124) My invention relates to improvements in cable anchors for wire cables, or ropes, the primary object in view being to provide for quickly and easily attaching anchors to ends of such cables, or ropes, without resorting to splicing, and whereby the anchor and cable cannot possibly pull apart.
Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claims are read with reference to the drawing accompanying part of this specification.
In said drawing:
Figure 1 is a view in side elevation of a wire cable equipped with my improved anchor, in its preferred embodiment,
Figure 2 is a view in longitudinal section taken on the line 22 of Figure 1 and drawn to an enlarged scale,
Figure 3 is a view in transverse section takenon the line 3-3 of Figure 2,
Figure 4 is a fragmentary view in side elevation of the cable, compression sleeve, and anchoring ends of the wire strands of the cable,
Figure 5 is a view in perspective of the com pression sleeve, and
Figure 6 is a view of the lead pellet.
Reference being had to the drawing by numerals, I designates a portion of the usual wire strand cable, or rope, and 2 my improved anchor at one end of said cable or rope.
The anchor 2, in the preferred, illustrated embodiment thereof, comprises an externally threaded shank 3 axially bored from what constitutes the inner end thereof to provide a y.- lindrical elongated socket 4 therein, said shank being provided on the other end thereof with the usual apertured axial lug for attaching the anchor to a fixture or the like, as will be understood. A gland nut 6 having a rear end i axially apertured, as at 8, for the extension of the cable I therethrough, is threaded onto the shank 3 against the outer end of a cylindrical compression sleeve 9 fitting around the cable I and extending part way into the socket 4. The compression sleeve 9 is smaller in external diameter than the diameter of the socket 4 and the ends of the wire strands I0 of the cable I are looped around the inner end of the compression sleeve 9 and extended back along the outer side of said sleeve 9 around the same, as best shown in Figure 4, to form anchoring ends I I on said strands. The inner end portion of the compression sleeve 9, with the described anchoring ends II of the wire strands I0, are embedded in a lead binder I2'filling the inner end of the socket 4 and forming a binder sleeve around the anchoring ends I I of said strands I0 bonding with said ends and positively preventing said ends from being pulled loose and out of the compression sleeve.
A particular feature of my invention is that the lead binder I2 is formed from a round lead pellet I3, shown in Figure 6, which is inserted in the socket l ahead of the compression sleeve 9. Said sleeve 9 with the anchoring ends II of the wire strands are then thrust by degrees against said pellet I3 under turning of the gland nut Ii onto the shank 3 and against the outer end of the compression sleeve 9. Under this operation the pellet 3 is flattened out against the inner end of the socket 4 by compression between said end of the socket and said sleeve and the end of the cable I, and iscaused to spread out around and over the anchoring ends II of the strands I0 in the form of an enveloping sleeve bonding with said anchoring ends and filling in the space between said ends and said sleeve and the Wall of the socket 4.
The foregoing will, it is believed, suffice to impart a clear understanding of my invention without further explanation.
Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the subjoined claims.
What I claim is: i
1. A wire strand cable provided at one end with an anchor comprising an externally threaded shank having a socket extending therein from one end thereof into which said cable is extended, a compression sleeve fitting around said cable and extending into said socket, said cable having strands at said end looped outwardly around one end of said sleeve and extending along the outside of the same longitudinally thereof to form anchoring strands, a soft metal bonding medium between the inner end of the socket and said end of the cable and between the wall of the socket and said strands and in which said strands are embedded. and a gland nut threaded onto said shank and bearing against the other end of said compression sleeve.
2. A wire strand cable provided at one end with an anchor comprising an externally threaded shank having a socket extending therein from one end thereof into which said cable is extended, a compression sleeve fitting around said cable socket and said strands and in which said strands are embedded, and a gland nut threaded onto said shank and bearing against the other end of said compression sleeve, said nut being operative to force said sleeve and strands into said medium and compress the same in said socket.
