=1 Claim.

This invention relates to new and useful improvements in cable anchors especially adapted for use in anchoring the stationary end of electric cables such as are used in conjunction with electrically operated traveling cranes and other machinery. .The stationary or anchored end of cables employed in conjunction with such machinery is usually located in the center of the transverse track and there the cable is subjected to a terrific strain and bending motion. Each time the crane travels over dead-center, the cable is flexed 180 and after this operation is repeated many times, the cable wears and causes electrical disruption and consequential shut down delays while repairs are being made.

It is, therefore, the object of the present invention to provide an anchor which eliminates most of this wear as the angle of bendis materially reduced and a considerable amount of the strain compensated for by the special construction of the cable anchor box Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 is a side elevational viewof a crane showing the improved cable anchor in side elevation and the pit which it is located in section.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 5.

Figure 3 is a section on the line 3-3 of Figure 5.

Figure 4 is a fragmentary rear elevational view of the anchor.

Figure 5 is a side chor.

Figure 6 is a section on the line 6-6 of Figure 3.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1, that numeral 5 denotes a trackway upon which a crane 6 or like vehicle travels. on this crane 8 is an automatic wind-up reel 1 for anelectric cable 8, while numeral 9 generally refers to the improved anchor for the cable 8.

The anchor 9 is situated in a pit l0 located between the rails. of the track 5. The anchor 9 comprises a triangular-shaped box ll having front and rear walls. Depending from the back wall of the box II is a tail portion l2 on which is located a bracket l3, this bracket I! having a elevational view of the anpivot pin l4 disposed through the upper portion thereof and through a barrel l5.

Numeral I6 denotes a clamp rising from the barrel l5 and having a curved lower portion, this clamp being split longitudinally to define two sections a, a which are flanged and bolted together as at l1 about the cable 8 and this is the fixation point of the clamp assembly. The cable 8 axially extends from an electric outlet box l8 secured to the front wall of the triangular-shaped box H, to the clamp l6 and fromthe clamp l6 upwardly through the box and through an opening in the intermediate portion of a slide plate l9 which covers the box and slides in a slideway 20, thus protecting the cable and the interior of the box ll against weather conditions.

As can be seen in Figure 3, the side walls of the box II are curved so that when the crane 6 is distantly removed from the anchor 9, the cable will describe but a slight bend as depicted in broken lines.

The box II has apertured lugs 2| to receive securing elements for securing the box in a desired position in the pit l0.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

An anchor for a cable comprising a funnelshaped box-like structure having flat front and rear walls, the rear wall embodyi a depending central tail-like extension, means for attaching a cable to the lower end of the extension to extend upwardly out of the structure, and comprising a tubular upright clamp pivotally mounted at its lower end on said extension for swinging between said walls parallel therewith to compensate for swinging movement of the cable between said walls, said structure having upwardly flaring edge walls to obviate sharp bends in the cable between said walls, and a cover for said structure through which said cable slidably extends, said cover being slidably mounted on said walls for compensating movement with said cable.
