TROLLEY-WIRE SUPPORT.

Specification of Letters Patent.

Patenten oet. 5', ieee.

Application inea March 20,'1909. serial No. 484,765.

i To all whom. it may concern:

v'itknewnthat-I, RorDEN O. CoUoH, a citizen of the Unit-edl States, residing at Charleston, m the county of Kanawha and tftate'of Nest Virginia, haveinvented certain new `and uset'ul Improvements in Trolley-@Vire Supports, of which thetollowing is a specification. 4

lMy invention relates to wire supporters or hangers, but more particularly to hangers for electric trolley-Wires and. has for its pur# pose to` provide a device of that character which -is applicable to be itted to insulators of any standard or special type; and wherein themeans for securing` the hanger toits supporter serves also as the means t'oi' securing the trolley-wire to the hanger; thus avoiding the use of intermediate fastening means-for the latter'.

IThe further purpose of the present invention 1s to provide a hanger ofsuch structure that by reason of its manner of attachment,` to the insulator will' effectively strengtheniv the joint between them, which joint in the i present used type of hangers is their point` of greatest weakness. The device is kpurposely designed to meet certain 'reipii-reinents of thetrolley railway system in mines and it has other advantages rendering it particularly useful in that service, which advantaies'will be pointed out in the course ot' the `iollowing description vand set torthin the claims.` l

ln the accompanying drawing wherein is shown my invention in its preferred structure, Figure 1 isa transverse sectional View of the saine, and Fig. 2l is a view 1n perspective showing parts of the device segregated.

Referring t0 the figures in further detailand wherein like numerals of reference indis corresponding parts in both views, 1 -i .-ignates an insulating or base block to which the hanger proper is secured. The .block 1 .isof substantially cylindrical design and is `jovided vwith an aperture therethrouglii'forlhe reception of .a securingbolt 2 having a pointed .screw threaded end` 3 by means of which the base block is fixed in position. 'lhe head tot the securing bolt 2 i" is incased within the space `between the hanger members and being thus shielded is guarded from such obstructions as would otherwise tend toloosen the bolt. A The upper marginal edge of the insulator block 1 is provided. with a-.depending or oveihanging ledge 5, the purpose whereof is to serve as a water shed for the insulator block and thereby increase the insulating etiect of the support as a whole by shedding thewater from' the hanger proper.

The trolley-wire engaging means coinprises [substantially a clamp formed of two like inenibers, which members are for their greater part of semi-cylindrical design and .have on their inner faces and coexte'nsive with the widtl'i'thereof ridges 7 adapted to BEST AvAiLAeLE ooFY4v tit within a .complementary annular' groove 7a formed within theinsulating block 1.

To effect amore perfect union between the member of the clamp and the base block, and.

vent relative movement between them and at the Sametime to permit a clearance'for the trolley-wheel of thecar. Both' of the members t3 have formed on their lower portions enlargements 1l and 13 which are per`r torated in alinement for the passage of a tie or securing bolt. 9 which with the nut 12 constitutes the means tor holding the clamp to the insulator block 1 and also as the means for engaging the clamp with the trolley-wire and holding the latter-'in suspension. The aperture through that portion 11 is of polygonal design in cross section whereby to receive and hold againstl relative turninginoveineiit a like designed shank10 of the bolt 9. That' portion 13 is so disposed with relation tothe body of the 'clamp proper that there is 4'freedom ofl movement for the turning of he nut 12,

and whereby the nut and that end of the bolt in engagement therewith, arewthin the plane o the sides of the clamp members: In order that the device may .be used in dierent parts of amine, there'is provided' an oifstanding lug 15 recessed to receive the end of the feed wire. provided on each of the clamping inen'ibers a perforated'lug 1G which when the parts are assembled provides a strain ear forja ystay wire.

'lo cover the overall dimensions of the insulator block and the several parts secured thereon thereY is av metallic plate or shed 17 disposed on top of the insulator 1 and held in that position by the bolt Q which passes centrally through-'said plate. The water shed is further serviceable in that it gives a seat or even base for the insulator block l and thus enables a betterl positioning of the trolley-wire. l

lIn order that the hanger may be readily suspended from a span wire, wire 18, there is provided on the upper face of the plate 1T a pair of oppositely disposed lugs it), each of which is under-cut and has a curved face 20 of substantially the saine contour as that of thespan wire. Goperative -with the lugs 19 is a peripherally grooved and `circular block 21 formed integrally with the platel?, and interposed between the nut 23 and the block 21 is a rubber and an iron washer Q4 and Q4 adapted to prevent Water from ruiming down upon the insulator. 'l`lie span' wire ii'tting within the groove is oit-set with respect to the lugs 1S) and is thus held against relative movement with the hanger. But the device is not restricted to this method of suspension; on the contrary it is obvious that the pointed screw threaded end-3 of the bolt :2 adapts said bolt to enter a timber oi' other fixed part suitable for suspension oi the insulator and in this latter method of suspension, the nut 23 can, of course be omitted, if desired.

From the foregoing description, itwill be vseen that by the peculiar manner of assembling the several parts of the trolleywire support the insulator block 1 servesl as a fulcruin for the clamp members 6 with respect to the trolley-wire 14 and in turn the trolley-dre 14 serves as a fulcruin with respect to the insulator block 1, the bolt i) thus serving the double purpose oi effect-ing a se cure union between those parts,

.Having thus described my invention what I claim as new therein' and desire to secure by Letters Patent is 1. In a trolley-wire support, an insulat- 'iiig base-block, a clamp adapted to grip the base-block and support the trolley-wire, and means flor simultaneously fastening the clamp t'o the wire and the base-block.
