Application filed May 8, 1915. Serial No. 26,676.

To all whom it may concern Be it known that I, JOSEPH KENNEDY, a

. citizen of the United States of America, and

a resident of New York, county and State of New York, have invented certain new and useful Improvements in Cable-Hangers, of which the followingis a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to hangers for suspending a cable or the like from a messenger wire or other suitable support, and has special reference to such as are known as cable claims.

Referring to the drawings,

Figure 1 is a perspective view of a hanger arranged and constructed in accordance with my invention.

A side elevation of the hanger in use is shown in Fig. 2, a messenger wire being shown in section and a cable being indicated by broken lines.

Fig. 3 is a view corresponding to Fig. 2

of the upper portion of the hanger before it is attached to the messenger wire.

Fig. 4: is a front view of the hanger in use. The hooked engaging portions of the hanger are shown on a larger scale in Figs. 5 and 6, the relation of parts while the hanger is being hooked on to the messenger and after it is putin position being shown in respective figures.

In erecting a telephone cable line or the like, the messenger wire is usually strung in posltion and then a plurality of cable hangers are clamped onto it by a man seated on a swing seat which is suspended from the messenger wire. The hangers are usually spaced about two feet apart and when all the hangers are in position in a span between poles, the cable is threaded through the hangers and pulled from one pole to another sliding along through the loops of the hanger. It is therefore evident that a satisfactory and elficient cable hanger must grip the messenger wire with sufficient firmness to avoid either longitudinal or torsional movement relative to the messenger wire.

It has been my aim to provide a hanger which shall fulfil these conditions and which at the same time can be very readily applied to the messenger wire by the man in the swing seat using one hand and without special tools or implements.

In general, the hanger of my invention comprises a double wire loop which in some respects resembles those of the prior art, but the engaging hooks of my improved hanger are especially constructed to grip the messenger wire in a new way whereby the possibility of either longitudinal or torsional movement relative to the messenger wire is rendered very remote. the fact that the hanger comprises a central hook which firmly gripsthe wire at two approximately diametrically opposite points, as for example, on the two sides of the messenger wire and a pair of spaced hooks one on each side of the central hook, each of which grips the messenger wire on two approximately diametrically opposite sides in quadrature relation to the sides gripped by the intermediate hook, as for example on the top and bottom.

aving special reference to the drawings, the hanger illustrated comprises a pair of loops 10 and 11 which are depended from a common two-part hook 12 at the top and This depends upon having its free ends bent to form hooks 13 and 1 1 located on the respective sides of the two part hook 12.

As clearly shown in the relative large scale views of Figs. 5 and 6, the bend in each part of the double hook 12 shown at 15 is of a smaller radius than that of the messenger 16, with which the hanger is adapted to be used, and the jaws of the hook diverge, forming a wedge-shaped opening to receive the messenger wire. Each of the hooks 18 and 1 1 is similarly formed but lies in a horizontal instead of a vertical plane, and consequently engages the top and bottom, ofthe messenger wire while the parts of the 'hook 12 engage the sides of the messenger wire.

Each of the hooks 13 and 141, is furthermore provided with a hump orshoulder 17 onits under jaw to prevent the messenger lfrom slipping out of the hook when once it is-in place. i g

. Another important feature of my invention isclearly illustrated in Fi gs. 2 and 3 of which Fig. 3 shows the relation of the hooks 12, 13 and 1 1 before the hanger is mounted on the messenger wire and Fig. 2 shows their relative positions after the hanger is clamped .in position. It is evident that the hooks 13 .gEtllCl lk are pushed downwardly relative to .resilient wire bent to form a two-part centhe hook 12 or in other words that the hook 12 is pushed upwardly relative to the hooks 13 and 14. This is further illustrated in Fig. 5 which shows the relative positions'of the hooks when the hooks 13 and 14:. have been pushed back and thehook 12 has been forced down onto the messenger wire. In order to -coniplete the attachingoperation the hooks l3 and 14: must be pushed down until the humps 17 may pass underthe wire after which they may be sprung onto the wire with a snap. The. resiliency of the springwire ofwhich the hanger is made will theneausethe- hooks 13 and 14 to exertan upward pressure upon the messenger w re to force it more tightly into the double book 12. i

The hanger is made-of spring wire or other resilientmaterialand it offers a very strong resistance to this displacement and consequently the messenger wire is very strongly forced upwardly by the hooks 13 and 11 into the wedgeshaped opening of the double ihook 12.

Detailed modifications may, of course, be

"effected within the-spirit and scope-of my invention and I intend that only such limitations be imposed as are indicated in the appended claims.

What I claim 1s: '1. A'han'ger comprising a single piece of tral hookhaving tapered openings'between jaws, adapted to engage'the sides ofamessenger wire, a pair of loops depending from the parts of the central hook, and end hooks having tapered openings formed in the wire near its respective ends and adapted to engage the messenger wire on the top and bottom.

2. A'hanger comprising a single piece of resilient wire bent to form a two-part central hook having tapered openings between jaws, lying in a substantially single longitudinal plane and adapted to engage the sides of a-inessenger wire, a pair of loops de pending from the parts of the central hook and spaced end hooks having tapered openings lying in a substantially transverse plane and openings of the end hooks on their under jaws, formed in the wire near its respective ends and adapted to engage- .the messenger wire on the top and bottom,-said humps being adapted to hold 'thewire firmly in the transverse hooks.

3. A hanger eomprisinga :two-part hook having tapered openings between .j aws lying csubstantially in one plane, a'pair of loops depending from the parts of said hook, and end hooks havingtapered openings lying substantiallyqin a plane :at right angles to thefirst andlocated one on each side of the two-parthook. j 1. A hanger adapted to be affixed to a wire or rod comprising a two-partitapered hooklying substantially inza vertical plane, a'pairo't loops depending from the parts of ;the hook, and end hooks lying in a'ho rizontal plane, the horizontaliplane of the end hooks being ofiset relative to the center of .a wire-or rod as engaged by the two-part hook, whereby said end hooks force the wire 'or rod into the taper ofthe-two-parthook.

5. A hanger comprising adjacent hooks having tapered openingsarrangedtoact in different directions :to each other and to have a supportingv wire wedged into said openings and a loop extending. downwardly from said hooks and adaptedto sup port a cable.

6. A hanger comprising a single piece of resilient wire bent to .form. a downwardly facing hook having a taperedopening arranged to lrave a. supporting wire-wedged into said opening, a tzLDSY'Gl'SG member adapted to be forced upwardly under said wire and to press the wire into said tapered opening; and a loop extending downwardly from said hook and said transverse member.

7. A hanger comprising a singlepiece of ;resilient wire bent to form a downwardly facing hook havingatapered opening arranged. to have'a supporting wire wedged .into said opening, a transverse hook also having a tapered openingxand adapted to humps or projections near the into the downwardly facing hook; and a loop extending downwardly from said hooks and adapted to support a cable.

8, A hanger comprising a single piece of resilient wire bent to form a downwardly facing hook having a tapered opening arranged to have a supporting wire wedged into said opening, a transverse hook also having a tapered opening and adapted to copies of this patent may be obtained for five cents each, by addressing the have the same wire wedged into its opening, the under portion of said transverse hook being arranged to force the Wire upwardly into the downwardly facing hook and having humps adapted to hold the Wire firmly in the transverse hooks.

In witness whereof I have hereunto set my hand this 6th day of May, 1915.
