CABLE HANGER.

Application filed April 5,

My invention relates to improvements in cable hangers and has for its primary object a cable hanger which is designed to be suspended from a messenger wire and which is provided with a longitudinally extending cradle or seat for the cable so that a contin uous longitudinal support will bev provided for the cable instead of the point support as is the cas'e with the present style of wire and cable hangers. V

A further object is to construct a cable hanger which can be readily attached. and detached to existing lines without the aid of tools, and which has substantially a V shaped longitudinally extending cable seat or "cradle. This peculiar shape of cradle permitting its ready application to cables of various sizes and giving substantially a long longitudinal support for the cable.

In the drawings:

Fig. 2 is *a side elevation of the same;

Fig. 3 is an end elevation viewed in the direction of the arrow in Fig. 1; I

Fig. 4 is a fragmental perspective view of the clamping and supporting hook; and

Fig. 5 is a fragmental perspective viewof the supporting hook.

In the construction of my device I employ a. hanger which is preferably made from spring wire, one end of which is provided with a snpp'ortii'ig hook 6. Formed integral with the hook '6 is an outwardly bowed arm 7-, this arm extends downward to a point 8, which point is designed to be directly be neath the messenger wire. When the hanger is attached from the point 8 the wire extends upwardly forming an end or arm 9, this arm is bent upward at an angle so as to form a relatively sharp bend at the point 8. The portion -9 is then bent so as to form a side member orfinger 10 the side member extends. in a direction parallel to the messenger wire 11. The side 10 is then bent so as to form. an end 12 which parallels the end or arm 9. Formed integral with the arm 12 and parallel to. the side 10 is a bottom member 'or'finger 13,.this member has formed integ ral therewith an end 14'which is parallel to the ends 9 and. 1-2. This arm or end 14 is also upwardly inclined (see Figs. 2 and 3). Formed integral with the arm 14 is a side or finger 15 which is parallel to the side 10 and bottom 13. The side or finger 1% has end 1924. serial no. 704.360.

16 formed integral therewith which is parallel to the end 14 and lies in the same plane. The end 16 extends downwardly to a point 17 from which point extends a bowed arm 18., this arm being bowed in theopp'osite direction to the arm 7. The arm 18 is ;pro vided with a horizontally extending portion 19 which is so bent as to pass beneath the messenger wire, and on the end of the portion 19 is formed a clamping and sup-porting hook20. V

,It will be noted from Fig. 3 that the sides or 10 and 15 are raised sufficiently above thebottom 13 so that when a cable is placed thereon, it will be held clear of the

arms

7 and 18. The sides or

fingers

10 and 15 bottom or finger 13 and

ends

9, 12, 14 and 1 6 form a cradle or cable seat which is substantially V shaped or angular in cross section. This feature :not only centers the cable over the seat but will also prevent its rolling around and shifting laterally therein, and at the same time when the cable is placed within the seat it will be supported longitudinally either by the bottom 13 or by the sides- 10 and 15. In this way the point contact with the cable is prevented and conse'quently the 'dangerioi kinking for sagging down is practically eliminated. I

It will be noted from Fig. 1 that the hook 20 is arranged at an angle to the messenger wire so that it will have a clamping eliect thereon.

In attaching my device the hook 20 is first placed over the messenger wire 11 when this is done the hook 6 will be laterally removed from the messenger wire and on the side opposite. from that shown in 2. The hook 6 is then brought down underneath the cable and over to the other side. This action causes the hook 20 to twist on the cable and thus set up torsion and gripthe messenger wire on two sides. The hook 20 is then raised sufficiently toclear the messenger wire and brought over so that when it is released it will-grip the wire. This flECtlOTLGHJUSGS torsion to be set up in the arm 19 which grips the messenger wire on the bottom andv forces the top o1 the hook against the top of the messenger wire; The torsion set up in the member 19 also exerts a downward pull on theh'ook 20 which prevents it from acciden-tally lifting 'oif, even though no cable is located within the hanger thus it will be seen that the clamping and supporting hook not alone supports the arm 18, but also has a clamping action on the top, bottom and both sides of the messenger wire thus effectually preventing the hanger from creep- 1n %Vhile I have shown the cradle as being substantially rectangular in plan, still this may be varied to various shapes without departing from the spirit of my invention, the essential feature being an elongated longitudinally extending seat or cradle which is angular or V shaped in cross section and which is so constructed as to have substantially a long longitudinal supporting surface and at the same time prevent the cable from contacting with the supporting arms. In other words, eliminate all possibility of point contact.

It is not essential that the bottom member or finger 13 be parallel to the

sides

10 and 15 but it may be arranged at an angle thereto, And furthermore if found necessary or desirable the

side members

10 and 15 need not be raised above the

arms

7 and 18 but terminate in the same plane so that these arms will also contact with the cable. The angularity or curvature of the seat or cradle member may also be varied with reference to its depth without departing from the spirit of my invention Having fully described my invention, what I claim is 1. A cable hanger constructed of a single piece of resilient material comprising abody portion provided with a substantially V- shaped cable supporting seat, said seat liaving plurality of contact points for the cable adapted to engage and support the cable on its opposite sides whereby the cable is prevented from lateral movement in its seat, spaced apart arms carried by the body portion so that the hanger may be applied to an existing cable without spreading said arms, the arms being provided at their ends with gripping means for engagement with a messenger wire, at longitudinally spacedapart points.

2. A cable hanger adapted to be suspended from a messenger wire, formed with arms spaced apart and adapted to grip the wire at points distant from each other, and an open seat, into which the cable may be freely passed between the said arms, the seat having contacting points to engage with the cable on its opposite sides and above its bottom or lowermost portion, whereby the cable is prevented from free transverse movement in its seat due to swaying of the cable with the abrasion incident to such movement.

8. A cable hanger constructed of a single piece, of resilient material comprising a body. portion formed into a substantially V- shaped, cradlelike, cable-supporting seat, said seat having a plurality of contact points for the cable adapted to engage and support the cable on its opposite sides and below its longitudinal axis, spaced-apart arms carried by the body so that the hanger may be applied. to an existing cable without spreading said arms, the arms being provided at their ends with gripping hoo s for engagement with the messenger wire at longitudinally spaced-apart points.

i. A c2 ble hanger constructed of a single piece of resilient material comprising a body portion provided with asubstantially V- shaped able supporting seat, the said seat having a plurality of contact points adapted to engage and support the cable on its opposite sides whereby the cable is prevented from lateral movement in its supporting scat, spaced-apart arms carried by the body portion so that the hanger may be applied to an existing cable without spreading said arms, one of said arms being provided with a hook. adapted to engage the messenger wire beyond the arm by which it is carried and having a portion between the hook and the cable-supporting seat adapted to engage the said messenger wire, and the other of said arms being provided with a hook .to engage the messenger wire spaced apart from the first mentioned. hook.

5. A cable hanger comprising an elon r gated angular cradle having its sides parallel to the longitudinal axis of a cable and furnishing a continuous support throughout its length therefor, said sides adapted'to make a continuous longitudinal contact with said cable, and means located at each end of the cradle for securing the same to a messenger wire. a

6. A cable hanger comprising torsional 3 supporting means for the hanger, supporting arms formed integral with said torsional.

supporting means, and a cable seat provided with cable. supporting iingers arranged parallel to each other and substantially parallel to the longitudinal axis of the supported cable whereby Said cable is. Supportedlongitudinally throughout the length of the seat. i a

7. A cable hanger constructed of a single piece of spring material, and comprising a number of laterally spaced cable supporting lingers, certain of said lingers being ar-' ranged in a plane below the other fingers,

and all of said lingers being arranged to continuously contact with a cable and substantially parallel to the longitudinal axis of said cable, EIDHIIII carried by each of the outermost fingers, a supporting hook carried by one of said arms, and a supporting and clamping hook carried by the other arm,
