Abstract

A cable chute adapted to guide into position beneath an existing messenger strand a plurality of cables which are to be permanently suspended from the messenger strand. The cable chute is designed to permit simultaneous handling of several cables, such as relatively fragile coaxial cables, without damaging the cables through inter cable contact. Additionally, the chute is self-aligning about both horizontal and vertical axes to compensate for variations in the position of the cable reel with respect to direction and elevation of the existing messenger cable.

Claims

1. A cable chute comprising:

a. a base frame, b. a supporting rod fixed to and projecting from said base frame, c. means for mounting said base frame on an existing member with said supporting rod projecting substantially vertically from said base frame, d. collar means rotatably received on said supporting rod, e. a pivot pin projecting substantially perpendicularly from said collar means and capable of rotational movement about an axis coincident with the axis of said supporting rod, f. a roller frame, g. means pivotally mounting said roller frame on said pivot pin for pivotal movement about the longitudinal axis of said pivot pin, and h. a plurality of rollers rotatably mounted on said roller frame with the axes of said rollers extending in substantially parallel relationship to said axis of said pivot pin and the cable engaging surfaces of said rollers defining a generally arcuate path curving about a center extending parallel to said pivot pin.

2. The cable chute of claim 1 further comprising:

a. gusset means for reenforcing said chute extending between and fixed to said collar means and said pivot pin.

3. The cable chute of claim 1 further comprising:

a. limit means projecting outwardly of said collar means for limiting pivoting of said roller frame on said pivot pin.

4. The cable chute of claim 1 further comprising:

a. means for retaining said collar means on said supporting rod.

5. The cable chute of claim 1 further comprising:

a. means mounted on said pivot pin adjacent said collar means for engaging and positioning a face of said roller frame in spaced relation to said collar means.

6. The cable chute of claim 1 wherein:

a. said plurality of rollers includes a plurality of sets of coaxially mounted rollers with the axes of said sets disposed in spaced parallel relationship to each other.

7. In a cable chute comprising a base frame, means for mounting said base frame on a pole, an upstanding supporting rod extending from said base frame, and a roller frame rotatably mounting a plurality of rollers with the cable engaging faces of said rollers defining an arcuate path, the improvement comprising:

a. a collar rotatably received on said supporting rod, b. a pivot pin attached to said collar medially thereof and extending substantially perpendicularly therefrom, c. a pair of substantially trapezoidally shaped gusset plates attached to and extending substantially tangentially from said collar to said pivot pin, d. a washer mounted on said pivot pin adjacent said collar and fixed to said pivot pin and portions of said gusset plates, e. a pair of limit rods attached to outer surfaces of said gusset plates and projecting outwardly away from said collar in spaced parallel relationship to said pivot pin and beyond said washer fixed to said pivot pin, f. said roller frame being pivotally received on said pivot pin, g. said plurality of rollers including a plurality of sets of rollers coaxially mounted on said roller frame with the axes of said sets disposed in spaced parallel relationship to each other along a generally arcuate path, and h. means on an outer end of said pivot pin for retaining said roller frame pivotally mounted thereon.

8. The cable chute of claim 1 wherein:

a. said base frame includes means for clamping said cable chute to a messenger strand.

9. The cable chute of claim 1 wherein:

a. said supporting rod comprises an elongated rod depending from said base frame.

10. The cable chute of claim 9 wherein:

a. said supporting rod is greater than twice the length of said collar means, and b. said collar means includes a plurality of collars rotatably received on said supporting rod.

11. The cable chute of claim 10 further comprising:

a. spacer means received on said supporting rod intermediate said collars.

12. The cable chute of claim 1 wherein:

a. said base frame includes a cross bar adapted to be positioned beneath and substantially parallel to a messenger strand, and b. clamp means is provided mounted adjacent opposite ends of said cross bar and adapted to be clamped to a messenger strand.

13. A cable chute comprising:

a. an elongated cross bar, b. means mounted adjacent opposite ends of said cross bar for clampingly engaging a messenger strand, c. an elongated supporting rod attached to and extending downwardly substantially perpendicularly from said cross bar medially thereof, d. gusset means extending between and attached to said cross bar and said supporting rod, e. a plurality of collars rotatably received on said supporting rod, f. spacer means rotatably received on said supporting rod intermediate adjacent collars, g. pivot pins attached to and extending substantially perpendicularly from each of said collars, h. gusset plates attached to and extending between said collars and their respective pivot pins, i. limit rods attached to outer surfaces of said gusset plates and extending in spaced parallel relationship to said pivot pins, j. roller frames pivotally mounted on said pivot pins, k. each Of said roller frames including a plurality of sets of coaxially mounted rollers with the axes of said rollers extending in spaced parallel relationship to each other and positioned along an arcuate path convexly curved toward said cross bar, l. means for retaining said roller frames on their respective pivot pins, and m. means for retaining said collars on said supporting rod.
