Patented Nov. 3, 1936 UNITI-:o STATES PATENT OFFiCE 2.059.825 l srsANnsn oN mom Application December 19, 1934, No. 753,199 4 c1. lol.. zic-s1) strength. stranded coole, usually called Ae. mese senger wire. The messenger wire provides tile tensile strength locking in the insulated electric 1o cobles, the letter usually being mede of copper, aluminum snol the like, while tlie messenger wires ere frequently mede of steel. At spocecl interveis, cable hangers ere orrcnged clone the mes" sensei wire to suspend the insuloteol electric is cellule..

The coi-lier types of cnlole hangers were lieuolly mede oi galvanized steel or copper welll vvire oi sumcient strength, which was hooked over the 'messenger celole end encircled about tile in suleted celoie. While in some ceses suoli prior wire hangers function setlsectorily from s. tensile strength standpoint, they ore coen to the serious objection tiret they out into the sheath oi the insulate/i celcle,` seriously injuring the some ond gli ultimately cousins the ieilure oi. the sl'leotl'l enel the lcoloie itseli.

Attempts lieve been mede to` overcome this olesa t' iectionelile lecture by the provision oi' lieneers ioctl oi merline, which encircles the insuletcfl 3@y coole enel the messenger onli is secured ley s epeciol type oi tietl lznot. in other etternpts to overcome tlie objectionnole ieuture oi the honger wires cutting into tllc celole, textile ioloric lionsm ess lieve lucen used lieving ttlnss or buckles 35 nucl tice like tor securing the seme to the niessenirer. Tile morline one the textile teorie lienuers ere open to the serious objection tlflet they ere subject to curly destruction due to ex unsure to the elements, it being obvious tilct they lo must withstood snow, rein end excessive temoereture cllnnges between seesons. This quickly rots tile orsenic materiels oi the textile teorie hangers enti results in en excessive meintenence oost, vvl'liclo oi? course is obiectioneble from un is economic stenclnoint.

To overcome the shortcomings oi the prior oroctice olt'ove referred to. suoli es the excessive ebreslon snol cutting oi the wires on the one lleno und the rotting or disintegration of the or l@ sonic morline or ieloric on the other hond, l ilove devised en improved cable henger involving the use oi o ribbon-like metallic breicl or felcricv which provides ,t cient bearing or Contact eren on tile cslole, to evoiol cutting of the sheath und to which is oleo proof eeelnst rotting to which orsonic materiels are subjected. Preferably, the ribbon-like henger is composed of e, multiplicity of strends oi metallic wire'of meteriei well suited to resist tile corrosive ection ci the elements, suoli preferable materiel for the wire sti-cutis being o. 5 ouprous motel suol-i. se copper. 'bronze or other alloy rlcli in copper.

This meneer, es :lo shown in Fig. 2, lies en intermediote portion vvrspneo stout tlie coole enel it servies ettecivlm ment ttinss i 'iliese nttings, es illustrsted in Fiss. l. to e inclusive, ore of lloolc-liire form. 'llliey nier be readily-'produced from stock size ce tubing somevvliet ilottenecl out by n pressing oneretlon, the ends of the honger riiolcons beine loser-tesi in the' tubing end then subjected to e swosing operetion. Alternatively, tlie tubing from vvliicl'l time ttinss ore m. may be subou jecteii to e. clrewins operation so es to ceusc `ou intimiste engagement with the strands of the ribbon-like henger. e svvesing or drawing op eration, it loe unclerstootl will ceuse the metal to iiow between the interstices of the strands and 65"' thus effect a secure mechanical engagement between the joined parts. Alternatively, if desired,

the ribbon Il may be secured by a rivet II, as illustrated in Fig. '7. And instead of employing l a tting oi' hook-like form, I may provide terminals of the character shown in Figs. 5 and 6, 'wherein one attachment fitting is provided with a keyhole aperture 20 adapted to be interlocked with the headed stud 22 on the attachment fitting A of Fig. 6. It is also contemplated that the hanger ribbon may be secured inplace by an attachment resembling a belt buckle with a tongue to tit into corresponding holes inthe ribbon, or I may employ a fastener similar to the type or belt buckle wherein a clamping action is obtained.

From the foregoing, it will be apparent that my invention provides an improved hanger in the nature of a ilat ribbon composed of a multiplicity of braided or interwoven strands which will give a maximum strength with a minimum weight and which cannot be readily destroyed by the elements and which would not have the objectionable feature of cutting into the cable or its insulation.

The hanger of my invention, while peculiarly well suited for supporting cables from an overhead messenger wire, is also suited for sustaining cables fromother overhead supports and it is also adapted for supporting pipes, or other 30 elements requiring suspension. vThe non-cutting characteristics of the hanger are particularly well suited for the hanging of heater pipes wrapped with asbestos or other insulation.

While I have described quite specifically the :,osasas embodiments of the invention herein illustrated it is to be understood'that the disclosure is to be interpreted in an illustrative rather than a limiting sense and the claims are to be construed as broadly as is consistent with the teachings of the prior art.

What I claim is:

1. A hanger of-the character described comprising a ilexible iiat ribbon of braided metallic strands having two flattened tubular hooks secured thereto, one of which embraces one er tremity oi the ribbon and forms one terminal el? the hanger and the other of which embraces the other end of theribbon and forms theopposite terminal oi' the hanger.

2,. A hanger of the character described comprising a ilat ribbon of braided non-corrodible metallic strands with flattened seamless tubular terminal hooks embracing the opposite ends of the ribbon.

3. A hanger of the character described comprising a flat ribbon of copper strands, a respective seamless tubular attachment terminal dtting secured to each extremityl of said ribbon, the two fittings adapted to cooperate in the suspension of a cable from an overhead support.

4. A hanger of the character described comprising a fiat ribbon of braided, non-corrodible metallic strands, flattened 'seamless tubular hooks embracing the respective ends of said ribbon, both of said hooks being adapted to independently engage an.overhead wire so as to support a cable in the bight of said ribbon.
