To all whom it may concern:

Be it known that .l, 31:01am A. lizlnno, a citizen of line United States, residing (iiilvlansiield, in the county of liichlnnd and a; State or ll/hi0. have invented a now and useful Suspension Device for Trolley-Wires or other Cowlnoiors Carrying Currents of High Voltage. of which the following is o specification.

'lhisinvontion relates to suspension do vices for-trolley wires orother conductors carrying currents of l h voltage.

The object of the in"; ntion is to provide a 'oonoirnotion which is'siinplc and elliciont 7. for .sus cnding irolley wires and other coni'luctors carrying currents of high voltage.

Other objects oi the 'lUYSlliliUI'l will appear more fully horoimitl ter. i

The invcnlion consists snhstnnlinllr in tho 2) i'zonsiruotion, coinbimilioin location and H2- in) my invention as Rppliokl to a coronary suspension-for trolloy wires. Fig. 2 is a detail view in side elovnlion of the insulator oinployeci in cormeotion with asnsponsion (levioo'of my ilivenfion. Fig. 3 is a View in sociion on The line 3----3, liig- 52, looking in the (infection of the arrows. 4, 5 and 9 are views in control longitudinal section of,

n'ioclifiod forms of "'nsnlntor onil'iracod. within the splrit and scope of my IDVGllilOl'l. Fig.

Rig 7 and 8 are views showing the application. of a suspension device embodying rho principles of n invention, and wire or other "conzlnotorl-v The same part is designated by the some reference sign whcrovcr it occurs through out the several views. 1

In tho use of cloci'ric currents of high Voltage for {no operairionof electric on s or othcr purposes, ii is (iosirahlo to supporit the trolley wrro or other condncior in such room,

is also desirable in some illr i'iillciib to sup-- portthe trolley wire or other ('OlELiLlCiOl' with as few sags or clips as on: iblc, thereby producing a. more nearly straight condition oi the trolley wire, for insinnre for ilie trolicy wheelflo travel along. This important in the where high speed of the our is desired. it is also dvesi z bin to support the trolley wire at frequent intervals as a precaution for no; safety of the public in case the trolley wire should break or fall. This is especially true whore the trolley wire or conductor carries a 'curreni of high vol- Luge. It is also desirable to provide :1 con-- siruction of suspension device of the nature referred to "which is inexponsive in mono-- 'fncl'i ro, and which may applied to change over the consiriictions at present in use for supporting or suspending tlfOllQ-;Y \Yiil'@5 car rying; cnrrent'of low volizige to a system (lo signed for carrying current of high voltage.

.Thc attainment of these and other desirable objects by a construction which is simple, ei'lioiont and economical of n'nnnrfachn-o is nnong the special purposes of 111y 13105011i, HTLVPUUOD. I

in the drawings reference-sign .Pi. designnies a post, designed ro be placed between or' to one side oi? the iracks of an elociric rail way romlbecl and from which the trolley arm or bracket of [tubular form, but I do not desire to ho'liiniiecl or restricted in this respect. This arm or bracket may loo supportecl upon the pos' A in any suitable or convenient manner, as, for instance, by means of a casting O secured to the post A, and, provided with a socket in which tho end of the arm or bracket B is inserted and clamped or held in any suitable or con venient manner, as, for instance, by means of the set screw Di If desired, the arm. or hrackot B only ho bracod to "the posh A in any snilza le inainior; for insizmco, and as shown in F1 0. i-omi 6 a brace rod is connected one l on in of casting l sccurocl'to the arm or hriliolzci ll,

and a'tqthe other end to the post A. This brace rod may be arranged above the bracket or arm B as shown in Figs. '1, o and 7, or, it

desired, a brace rod G connected at one end to a casting H on the post A, and at the other end to a casting 'd on the arm or bracket B, said bracea'od G being located below the arm or bracket Upon the outer end of the'aim or bracket B is receiver an insulator K.

In practice, and. preferably, the insulator is provided with a central bore longitudh.

nally therethrough", through whiclrthe cnd of the'arin or bracket B is designed to he slipped, the insulator being held against cnd wise nmvement upon the arm or bracket B in any suitable or movement manner, as, for

instance, by means of collars L Suitebly secured upon the arm or bracket B.

The insulator K may be of any suitable n'iaterial such as porcelainor other insulating material, and the specific construction of the insulator may be varied throughout a wide range without departure from the spirit and scope of my invention, the'essentiial feature being the provision of an insulator adapted in support either directly or indirectly a inegrseiiger wire from which a trolley wire or othe'i conductor may be suspended or supported, or else adapted to suspend the trolley wire or other conductor directly, us will appear more fully hereinafter.

l t is obvious that the messenger. wire, trolley wire or other con dncior may be suspended from or supported by the insulator K in many specifically dill'erent ways. For inetance, in the drawing in Figs. 1, 2, 3, 6, 7 and 8 I have shown the insulator K provided with a central peripheral groove or scat, indicated at M, (see Fig. in which i: received the arms N O of a casting, said arms being clamped together by a bolt orotherwise,:.1s indicated at P, at one end thereof, and at the other end being pivoted or otherwise connected together by a' pin Q, from which pin may be suspended a clamping device or hanger. This hanger or clamp device may be of any suitable or convenient type or construction.

in Figs. 1, 3, 7 and 8 I have shown a" straight wire hanger ll of ordinary construelion, dceigned to be suspended from the bolt or pin Q, and to receive and support a trolley wire or conductor or messenger wire, from which the trolley wire or (,(HldllClOl' may in turn be suspended. in Figs. 1, 7'and 8 l have shown the hanger R enpportiiu, a messenger wire 8, but-it IS,()l)V1OIlS that the trolley wire or conductor nn 'ht with equal tacilil'ybe carried, or supported. by the hanger li. In Fig. 6 I have shown a clamp dcvii'o 'll ol somewhat dillcrenl constru tion fillu'lllflild i'rom the clamp band which is ap pliod. lo th insulator A, but Wl)i(ll clamp ordinary or etaiulurd ur etruction designed to clamp and suspend directly a trolley wire or other conductor A. it is obvious, however, that a clamp device ol the construction shown in Fig. 6 at 'l may with equal facility be employed to suspend a messenger wire instead of a trolley wire or other conductor, and such trolley wire or other conductor suspended from the messenger wire in any suitable or convenient manner, as, for instance, bymeansof snsparticular and specific construction of the clamp device or hanger used is unimportant, so far as the principles of my invention are concerned. It will be understood, of course, that in the messenger wire construction the trolley wire or other conductor will be suspended from the messenger wire at frequent intervals, whereas the messenger wire will be supported or suspended by or from the ineulator K on the brackets or arms B only at the intervals of the posts A along the roadway.

in Fig. 4 l have shown a modified Form of insulator K, having a central peripheral groove or seal M, and a longitudinal central bore 1 tlu-rethrough to be plecvod upon the end of arm or bracket l..

In Fig. t) I have shown another modified Form of insulator K",- providcd with a central peripheral groove or seal similar to tho groove or heat M of the construction shown struction shown in Fig. 4-, r-fo as lo-cnablo the Same to be sleeved upon the end of the or bracket B. The form shown In Fig.

more nearly cylindrical in shape than the form ahown in the other figures ol the draw- .ing, and tor this rcusolris economical in manul acturc. it is obvious, however, that i'nzt'ny other specifically ditl'crcnt torms or shapes of insulator may equally well answer the purpose. be limited or restricted to the exact details of construction of insulator.

lmtcad of suspending the messenger wire,

trolley wire or other conductor by. means of a strap or band, such as N, O, and a sua pending, hanger or clamp It or .l,such wire or conr'luctor may beeuspcndcd in any other suitable or convenient manner from the iii-I uilaloi'. as, for insl anc'c, by moans of a wire or rod l), ale shown in Fig. 5, v uid wire or i-od l) passing around the conductor or-lrol-- l do not desire, therefore, to;

' heal h the arm or. bar B and bracing the seme'lrom the the wire S shown in F insulator. It is alsoobvious that, if desired, the messenger wire ma y rest upon the insw later and be held thereon 'iinst danger of accidental l'lisplaceaient from its seat in the insulator ii. an suitable on convenient munner, as, for instance, by the Weight of themg; is, however present to a greater degree in the case of the messenger Wire construction than in the case Where the trolley Wire siuiiported upon or suspended directly lrom the insulator. It is especially desirable to so brace the trolley Wire Whether fillpilltil'lill upon or susaiended directly from the insulator or from a messenger wire at curves in the roadway, and puii'ticulzirly where the trolley Wire is suspended from a inessmiger wire, in which case the trolley wire liable to be pulled over too far by the crosslnraces or pull-over wires.

it is slso among the special purposes of my invention to providea construction for suitably bracing the trolley Wire against being pulled over out of proper alinenient with the rozulbed, and this object may be accompli led in many dill'erent ways, and. in Figs and have shown an application ot' my invention in various Ways to the ac complislnnent of these objects. In Fig. 7 l have shown an insulator li, similar in all respects to insulator K, and having a band strapped around the central part thereof similar to the band comprising the arms h and U of Fig. 3, and from which is suspended a fitting 'l", to which is connected a. brace arm E, said brace arm being connected by means of a clamp T to the trolley Wire vAll. In this instance the insulator K is placed. upon the brace (ll arranged be post A, said insulator being held thereon by collars L, similar to the collars L for holding the insulator K on arm or bracket B. it is obvious, however, that; the insulator K and sleeves L may be otherwise suitably supported; for in stance, in Fig. 8 l have shown theiinsulator mounted directly upon the arm 5, and cona led through brace arm E and clamp d.e-'

vice l to the trolley Wire A. in this instance the under brace G is dispensed with.

it is oh'\ 'ious th't n'iany variations and changes in the 11;: the trolley Wire againstlateralsway let-ails constiiuctniu and arrangement would readily occur to persons sh lied in the art and still full Within the spirit and scope of n'ivcntion, I do not desire, therefore, to be limited or restricted to the exact details of construction shown and descrihed. lint l-lavmg now set forth the ObJEECl? and.
