CABLE-SUPPORT.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Application filed December 29, 1920. Serial No. 438,768.

To all whom it may concern Be it known that I, ORSON W. BRENIZER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cable-Supports, of which the following is a specification.

This invention relates to lIIlIJlOYt-BlllfllltS in cable supports adapted to be hung at intervals upon a supporting or messenger wire to receive and support a cable therein, the messenger wire being formed of a plurality of strands twisted around a central or core strand and providing the messenger wire with relatively large and small diameters in alternate succession, forming intermediate shoulder portions.

The object of the invention is to provide a cable support of novel, simple and eflioient construction which may be formed of a single piece of spring wire and having provision first, whereby shoulder portions of the messenger wire may be utilized to prevent displacement of the cable support lon itudinally thereof, in a construction empdoying hooks to attach the support to the messenger wire, Without requiring a spring pressed gripping of the hooks against the messenger wire to prevent the hooks from leaving it while a cable is being drawn through the support; second, whereby the cable support may be constructed of a relatively short length of wire and possess many advantages not possessed by prior constructions which do not require a greater length of wire, thereby resultin in a great saving of material; and, thir whereby many advantageous results are attained.

The invention consists in the novel construction, combination and arran ement of parts hereinafter described and c aimed.

In the accompanying drawings, illustrating my invention,

igure 1 is a transverse section through a supporting or messenger wire haying cable support applied thereto embodying my invention;

Fig. 2 is a side view thereof.

Fig. 3 is'atop view thereof.

Figs. 4 and 5 are enlarged, transverse "seetions of the messen or wire on lines and 5-=-5, res 'ectitieyl, of F ig. 2, showing the two cable anger ooks applied thereto.

Fig. 6 is an enlarged transverse section of the messenger wire.

Referring to the drawings, 2 designates the supporting or messenger wire which comprises a central or core strand 3 and six outer strands 6 lying side by side and twist- 0 ed in spiral form around the core strand 3, as clearly shown in the drawings. A messenger wire of this character has relatively large and small diameters, which occur in alternate succession longitudinally of the 05 .WHG, as indicated at 7 and 8, respectively, n Fig. 2, and which extend continuously, in spiral form around the wire 2 from end to end thereof, following the lines of its twisted strands 6. These alternating large and small diameters are also indicated at 7 and 8, in Fig. 6, where it will be observed that each of two parallel lines which touch opposite sides of the wire 2 at one of the small diameters 8 thereof also touch two of its twisted strands 6.

The cable support is formed of a single piece of spring metal, and it comprises a on t le-receiving loop 9 extending beneath the supporting or messenger wire 2, hooks 1O and 11 formed on the respective end portions of the loop 9 and an arm 12 formed on and extending from the hook 10.

The books 10 and 11 are hooked around and over the supporting wire 2 from opposite sides thereof to connect the cable support thereto in a manner to permit it to act as a support for suspending a cable, indi cat-ed at 13 in Figs. 1 and 2, from the sup porting wire 2. I

The oppositely disposed faces 14 and 15 of the hooks 10 and 11, respectively, extend parallel toeach other, and the distance between the faces 14 of the hook 10 and the faces 15 of the hook 11 are each less than the large diameter 7 of the supportin wire 2 and but slightly in excess of or so Stan tia-lly equal to the small diameter 8 of the su porting wire, for a purpose hereinafter described.

The loop 9 extends transversely of the supporting wire 2 for the rece tion ofthecable'13,and the si db arms 0 the loop-9" diverge from the bottom of the loop longitudinally of the supporting-wired to space 105 thehooks 1-0 and 11 and permit such to 1 hooked around and over the supper-tin wire 2 at one of the small diameters thereo spacedfrom the other, asclearly shown in the drawings. The hooks 10 and 11 are set in arallel relationship and to extend at rig t angles to the supporting wire 2, and the distance between the centers of the hooks l0 and 11, both before and after the cable support is applied to the wire 2, is equal to the distance between the two spaced small diameters 8 of the supporting wire 2 which receive the hooks.

The arm 12 extends from the hook 10 in the direction of the length of the wire 2 and away from the hook 11, and its free end extends downwardly below the plane of the top of the supporting wire 2 to engage the same on the opposite side thereof to the side occupied by the curved body portion of the hook 10, for a purpose presently appearing.

'The'rrelation of the .parts of the cable support to each other, before and after the support isapplied to the supporting wire 2, is the same or substantially the same as shown in the drawings; and, in applying the support tothe wire, the hook 10 is first applied to the wire 2 at one of its small diameters 8. In applying the hook 10 to the wire 2, the cable support is turned and manipulated to pass the arm 12 over the Wire 2-.in advance of the hook 10, and,thereafter, the hook 10 is engaged with the wire 2.? The hook 1O fits the wire 2 sufficiently loose to allow it to be rocked enough to permit the hook 11 to move under the wire 2 while the hook 10 is being applied thereto. After the hook 10 has been applied to the wire'2, the hook 11 is moved beneath the wire 2 in the direction of the arrow 14 by springing the loop or bod 9 of the support until the free end of the ook 11 clears the side of the wire 2 on which the arrow 14: relocated; whereupon the hook 11 is raised and en aged withthe wire 2 as illustrated 1 against the wire 2.

mthe rawings, while the loop or body portion 9 of the supportis permitted to spring back to or toward its normal condition. When the hook- 11 is thus applied-to the wire 2, the loo 9 is sprung in opposition toe pressure [of t e hook 10, 1n the dlrection of -the-arrow 15, against the wire 2 and in opposition to -pressure of the free end of the arm 12;, in the direction'of the" arrow 16,

1 he'oable support may be removed from the wine 2, when desired, by a reversal of the operation than thereto; 1 i a It will now be understood that, when the oable"support is applied to the supporting wire 2 therefor, and a cable is drawn through the 1oop9 in either direction, the arm 12,

engaging one-side of the wire 2 will pre ivent-the hook-10 from being accidentally disengaged from or leaving the wire 2 while the hoe just described for its applies-y 11 is engaged therewith, and that the hook 10 and arm 12 will cooperate to prevent the hook 11 from being accidentally disengaged from the wire 2, by requiring the loop 9 to be sprung from the condition shown in the drawings for such disengage ment.

When a cable is drawn through the loop 9 of the support, in either direction, the hooks 10 and 11 will engage the shoulders formed between the large and small diameters 7 and 8, respectively, of the supporting or messenger wire 2 and thereby prevent the cable support from being displaced longitudinally of the wire 2 during the cable drawing operation.

Of course, the normal condition of the cable support, before it isapplied to the supporting wire 2, may be such that, in applying it to the wire 2, it will be necessary to spring the loop 9 to such an extent that the hook l0 and arm 12 will continue to exert pressure against the wire 2 in the directions of the arrows 15 and 16, respectively, and that the hook 11 will exert pressure against the wire 2 in the direction of the arrow 17, after the application of the cable support to the wire, but such pressure is not necessary either to prevent the accidental disengagement of the hooks l0 and 11 from the wire 2 or to prevent the displacement of'the cable support longitudinally of the wire 2 when a cable is drawn through the loop 9 in either direction I claim as my invention:

The combination with a supporting wire having relatively large and small diameters in alternate succession, of a cable sup )ort comprising a cable receiving loop exten ing beneath the supporting wire, a hook on one end portion of said loop en aged with said wire, and a hook on the ot or end ortion of said loop andengagedwith said wire and extending around one side thereof and hav ing an arm extending therefrom in the direction of the length of said 'WlIG and adapted 'to engagewthe opposite side thereof to prevent the accidental disengagement of said hooks from the sup 'orting-wire,l-each of said hooks engaging-t c 51703) and bottom of the supporting wire; one of ,SillilllQOllS having two opposing faces adjacent to two opposite sides of the supporting wipe at one, of it's small diameters, the distance between; said :taces being less than the adjacent large diameter of the supporting wire, whereby, displacement of the cable support longitude nally of 'the supporting wire imprev-ented without theaid ofan'y springpressed grip ping action of the cable support upon thesu porting wire, p
