- FIGG 11/00 Field of Search 403/177, 212, 215, 210, 403/211, 209. 24/115 H, 115 11,1226;
- ABSTRACT A wire grip which easily and quickly secures several 1561 References C'ted wires for pulling through a conduit.
- This invention relates to a wire grip comprising two lengths of wire rope which are axially staggered so that individual wire grips secured to each of the wire rope is correspondingly axially staggered providing use of the wire grip therefor in smaller conduit.
- FIG. I shows the wire grip with the wire rope axially staggered to provide a staggering of each individual wire grip.
- FIG. 2 shows a side view of FIG. 1 with individual wire grips axially staggered.
- FIGv 3 shows the loop end view of the two wire ropes showing a smaller diameter of the wire grips overall.
- FIG. 4 shows an end elevation of the grip end.
- FIG. 5 shows a sectional view of how the wire grip pulls all sizes of conductors through a conduit.
- FIG. 6 is a cross-section view of a conductor wire held in a wire grip by opposed set screws.
- FIG. 7 shows a single wire grip
- the reference numeral 10 indicates a wire grip embodying this invention for drawing electric power cable or wire through conduit.
- the wire may be of any type having core wire strands or multiple wire strands such as shown in FIG. I and FIG. 6 as element 20.
- the wire grip 10 comprises two individual wire ropes 30, 40, of equal length which are axially staggered so that the wire rope includes grips l and 4 and wire rope includes grips 2 and 3.
- the lengths of the wire rope need not be equal in length, but of varying length. That is, the lengths of the individual wire ropes can be of different lengths so long as the wire grips are axially staggered with respect to each other.
- This double loop portion is used with a pull rope so that the wire grip can be pulled through a conduit, as shown in FIG. 5.
- each grip secured to the end of a wire rope comprises threaded bores 19 extending transversely through the body.
- .Iam screws 18 are threaded therein through the body by any means, however. normally an allen wrench will fit the recess 2
- the jam screw I8 is forced against the wire 20 deforming it and causing it to bend and partially enter the opposite end of threaded bore 19.
- the threaded bores 19 extend at right angles to respective planes containing the body cylindrical axis 25 of each grip and along the side walls to provide positive thread engagement for the jam screw 18. This feature also provides for reversing the jam screw when the threads on one side of the bore are damaged.
- This invention is primarily directed to a plurality of wire grips which are axially staggered so that the wire grip passes over sheaves, and through elbows in conduit more easier than any previously known method or apparatus.
- FIG. 3 and FIG. 4 shows that by axially staggering each grip an overall smaller diameter is obtained thereby allowing the wire grip 10 through smaller conduit as shown in FIG. 5.
- FIG. 7 shows an individual wire grip l' with a wire loop portion 52 comprised of two individual wire ropes 54 and 56 crimped by a collar 12'.
- a single wire rope can be used in lieu of the double wire rope.
- the wire grip consists of ajam screw I8 threaded into bore 19 as in the previous embodiment.
- a wire grip for drawing multiple strand wire through a conduit comprising:
- said grip means axially staggered to provide a smaller diameter thereby allowing said wire grip through said conduit.
- each of said grips comprises:
- jam screw means threaded into said threaded bore means for securing stranded wire.
- the gripping means of one wire rope being at the formationextreme end portions of said linear displacement car displacement formation and are between said extreme end portions in said linear displacement
