Gelak AttorneyRoger M. Hibbits [57] ABSTRACT Cable clamping means comprising first and second face plates disposed essentially parallel to each other and provided with apertures therein, elongated spacers operably mounted between said face plates providing a wedge shaped space therebetween, a clamping block operably disposed within said wedge shaped space, and a hollow cylindrical eyelet operably disposed through said apertures in said face plates and clamping block.
2 Claims, 6 Drawing Figures WEDGE CLAMPING DEVICE FOR CABLE BACKGROUND OF THE INVENTION This invention relates to new and useful improvements in cable clamping devices, applying particularly to cables which are used in conjunction with excavating machinery hoists, tuggers, winches, draglines and guy wires.
, SUMMARY OF THE INVENTION It is accordingly a primary object of the present invention to provide an improved cable clamping device.
It is another object of the present invention to provide an improved cable clamping device which is simply and economically manufactured.
It is a further object of the present invention to provide a cable clamping device which is more efficient.
It is a further object of the present invention to provide a cable clamping device which is simpler to use.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of cable clamping means constructed in accordance with and embodying the present invention.
FIG. 2 is a perspective view of a sliding block for use in the cable clamping means shown in FIG. 1.
FIG. 3 is a fragmentary sectional view of the cable clamping means shown in FIG. 1.
FIG. 4 is another fragmentary sectional view of the cable clamping means shown in FIG. 1.
FIG. 5 is a fragmentary sectional view showing another arrangement of the cable clamping means as shown in FIG. 3.
FIG. 6 is a fragmentary sectional view of another arrangement of the cable clamping means as shown in FIG. 4.
DETAILED DESCRIPTION OF THE INVENTION Referring now to the accompanying drawings in detail, the cable clamping device, 1, in its preferred embodiment comprises face plates, 2, disposed essentially parallel to each other. Elongated members, 3, which is a flat bar, and, 4, which is a flat bar curved at, 12, are interposed between face plates, 2, a wedge-shaped space being thereby provided between elongated members, 3, and, 4. Eyelet, 5, extends through appertures provided in face plates, 2, and the wedge-shaped space between elongated members, 3, and, 4. Eyelet, 5, may be secured to face-plates, 2, by welding as shown in FIG. 1. Sliding block, 6, shown in FIGS., 1, and, 2, is in the form of a wedge having non-parallel sides which arcuately meet at the large end of sliding block, 6. Sliding block, 6, is provided with elongated apperture, 7, which allows movement of sliding block, 6, relative to eyelet, 5. Elongated members, 3, and, 4, are installed between plates, 2, essentially parallel to the corresponding sides, 8, of sliding block, 6. In operation, cable 9, is passed between elongated member, 4, sliding block, 6, and face plates, 2, about sliding block, 6, and returns through the space between elongated member, 3, sliding block, 6, and face plates, 2, and terminates in cable end, 1 1. Cable, 9, is shown in FIG. 1, fragmented at cable section, 10, which would be the end of cable, 9, which would go to a load. In operation the line of force or tension on cable, 9, would be nonparallel to elongated member, 4, and an arcuate bend, 12, is provided in elongated member, 4, to minimize strain on cable, 9, at the point where bend, 12, is provided. For purposes of illustration, a pin, 13, is shown passing through eyelet, 5. In operation pin, 13, would be connected to an external source of power such as a tractor.
Tension on cable, 9, in the direction of section, 10, forces sliding block, 6, towards the narrow end of the wedge-shaped space provided by elongated members, 3, and, 4, and thus ca ble, 9, becomes clamped between sliding block, 6, and elongated members, 3, and, 4.
FIG. 3 shows in greater detail the relationship of face plates, 2, sliding block, 6, eyelet, 5, and cable 13.
FIG. shows in greater detail the relationship of face plates, 2, elongated members, 3, and, 4, sliding block, 6, and cable, 9.
FIG. 5 shows another embodiment of the present invention, wherein the eyelet, 5, of FIG. 3, is replace by eyelets, l7. Eyelets, 17, may be eliminated by using bosses on the exterior surfaces of face plates, 2.
While I have, illustrated and described preferred embodiments of my invention, it is to be understood that changes and modifications in the form, construction, arrangement and combination of the parts and steps of the cable terminating means and methods of making and using the same may be substituted for those herein shown and described without departing from the nature and principle of my invention.
Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
