Application. filed Gctober i1, 1915. Serial No. 55,241.5.
.To @ZZ whom 2'?? may concern.'
Be it known that l', leeren BLACKBURN, a citizen of the United States, and resident of Webster Groves, liffi-issouri, have invented Certain new and useful linproveu'lents in Cablelangers, of which the following is a specification containing a full, clear, and exact deseription, reference being had to the accompanying drawings, forming a part hereof. i
My invention relates. to improvements in cable hangers 'wherein a support is provided, for a cable, having means for suspension from a messenger and means for holding the suspending means against movement lei'inthwise relative to the messenger.
'lne object of my invention is to constructa device of spring wire for the support of aerial cables suspended freni s messenger or span wire which may be applied "mthont the 'use of tools to existing lines and which is designed to prevent lrinking of the cable and to be locked to the messenger or span Wire to preserve spacing.
With the above object in View my invention relates to Certain novel details o1 construction and arrangement of parts, herein yafter fully set forth, pointed ont in my Claims und illustrated the eeeornpanying drawings, in whichff igure 1 is plan of one of iny improved sable hangers applied to messenger;
2 is an elevation oli hanger as applied to messenger and shows by dotted lines a cable supported by the hanger; and
Fig. 3 is an end vView of the hanger as shown in Figa 2 looking toward the looking end.
Referring by numernls to the accompany ing drawings,l 5' designates the body of the hanger which is of cradle formation, that is, comprises the spaced ling-'ers A, E and C upon which the eable 6 shown only by dotted lines, is supported at more than one point to maintain it in a straight line in or der ob'viate lrinlring as is common in the support of leaden cables. l
As shown the entire structure is made up from a single piece et material, preferably steel wire, and hence the ingers n, B and C of the eradle like body are joine l by the; curved portions and 8. By preferente, elsa7 ythe fingers A, B and C are dished es shown Fig. 3 to contorni morenearly with the cable and to present relatively long bearn ing` surface for the cable which further tends to obyiate cable bending or lrinlring.
Arising from and forming integral oontinuations of the iingers A and C, ot the Cradle like eeble supporting body, are the arms 9 and 10, the arm 10 terminating With a hoohy 11 whereby it may suspend from a messenger or span Wire 12 and the arm 9 having at its uppermost end an integral Wrist or substantially straight portion 13,
which carries at its free end a hook 14, which is a companion to the hook 11 and constitutes therewith the means for suspending the. hanger from the `messenger or span Wire, and also provides the means for loek- As shown in Fig. 2 the Wrist 13 is shown i to be substantially parallel with the span wire.l which is its true position when epplied, but it is to be understood that normally this Wrist inelines downwardly and outwardly from the arm 9 to the'hoolr 14 and occupies a plane, relative to the plane of the lingers A, B and C higher than the hook 11, thus necessitating a bodily strain of the entirestrueture including the cradle like body and the Wrist 13 to v'place the two hooks 11 and 14 over a span Wire. The sub-- stantiaily straight portion or yWrist 13 cariied by the arm 9 is of greater length than the diameter of the span Wire, and when the hanger is in use said portion extends at an angle to the longitudinal axis of the span Wire, and exerts a yielding upward pressure on the underneath surface thereof. The said portion 13 oontaets on the underneath surfaeef oiA the span Wire and the bent over or overlying portion of the hook 1% contacts with the upper surface of the span Wire at a point beyondor laterally' removed from the contacting point of the portion 13 of? the Wire and exerts a downward pressure thereon. Wien the hanger is applied, as
shown in Fig. 1j it will be observed that not only the portion 13 ooeupies an angle other than a` right angle to the longitudinal axis of the span Wire, but the portion of the hoolg overlying the span wire is also arranged at an angle other than a right angle to the span Wire, and at an angleto the portion 13.
It is to beobserved further that the-Wrist 13 in addition to the incline just referred to stands at Aan angle relative to the span wire,
Vand issubstantially at right angles to the hook 14rtlereby causing the hook to betorsionally clamped to the span wire.
tBy this arrangement of the parts, it is obvious 'that the hanger may be applied to existing span wires and cables.
ln applying my device the hook 1s'- is iirst placed over the span wire, with the bodyT and the other hook 11 swung laterally 'from the span so that the Cable may rest between the arms 9 and 10 and over the fingers A, B and C.
With the cable thus resting the entire hanger swung to bring the hook l1 to position on the span wire7 that is, the entire structure is swung on the book 14, to bring the hook 11 to position on the cable, which necessarily springs the wrist 13 both laterally and vertically relative the span wire thereby eausing the Wrist 1? as Well as the hook 11i to bind against the span. Wire and thus hold the hanger against movement whereby to lpreserve relative spacing.
Haring thus described my invention, what l claim as new therein is:
1. A cable hanger comprising spaced iingers arranged to support, but not surround a eab-le7 arms spaced apart and curved in opposite direi-tions formed integral with certain of said dogersv1 hook earried by one of said arms? and a yielding, Clamping means carried. l'y the other arm, said clamping means exerting and maintaining a yielding Vertical pressure'on the messenger wire when the hanger 1s applied.
2. A. cable hanger constructed of a single,
piece or' material and comprising` a number or laterally spaced and curved lingers7 arranged 'to support7 but not Surround a Cable, an arm ear'g'ied by each of the outermost on es of said lingers, a hook carried by one of said arms7 and a yielding o amping means ear- .ried by the other arm for preventing creepof the hanger when applied to the messonger.
3. e. cable hane'er formed *from a single piece of spring wire comprising a body portion affording a seat for a cable, arms earried by the bodyportion bent outwardly and spaced apart so that the hanger may be applied to an existing cable, Without spreading the arms apart, one of said arms provided with a hook adapted to engage a span Wire on its top'.1 surface at a point beyond the arm by which litis carried and with 'a substair v fthe span wi needles tially straight and yielding` portion interme diate said hook and the cable supporting seat, said portion being` of greater length than the diameter of the span 'Wire and arranged to engage said wire on its underneath surface, andthe other oit said arms being,` provided with a. hook arranged at an angle to the iirst mentioned hook adapted to engage the span wire on its top'surtaee 4. As a nenr article ol manufacture7 a cable hanger formed from a single piece of resilient material, one end being` provided with a suspending hook terminatingy in `a leve." arm adapted to be positioned beneath a messenger Wire, a body portion formed oi' a series of suspension points or surfaces ar ranged at an angle to the axis of the niessenger and a cable to be supported thereby, the other end ot the hanger vterniinenting; in hook spacern apart from the first mentioned hook, thus aording an inerea sed leverage by means of which the hanger .may be applied to or removed from the messenger wire.'
5. A cable' hanger comprising a cradle like body, open topped, 'whereby a oable may be supported thereupon Without threading the cable through the device, a suspendingl arm at eaoh end of the device7 a hook at the end of one arinat approximately right angies to the longitudinal ot the devine., a Wrist at the 'free end of the other suspending arm a hook at the 'i end oi. said wrist arranged at an angle other than a right' angle to the longitudinal anis of the device.
