TROLLEY-WEEEIJ MOUNT.

To rzllwlmm it may concern: I i

Be it known that I, THOMAS SANDE S, a citizen of the United; States, residing, at Kingman, inthe county of Fountain, Indiana, have inventeda new anduseful Improvement in Trolley-lVheel Mounts, of which the following is a specification. 7

My invention relates to that class of trolley-wheel mounts, wherein a substantial mount is provided whereby a trolley-wheel is supported inbearings, and upon the extreme end of a trolley-pole, and the objects of the invention are: first, to providea suitable bearing and support for a trolley-wheel upon the extreme end of atrolley-pole; sec- 0nd, to provide such a trolley-wheel mount. which by reason of its pecular structure and attachments, permits an automatic adjustment in the position of the trolley-wheel while traversing a curve, for the purpose of avoiding the danger of the trolley-wheel jumping the wire; and third to provide such a trolley-wheel mount, which will be substantial, sightly and safe against dis placement; These objects I attain bymeans of the mechanism illustrated in the accompanying drawings, in which Figure 1, is a side viewof the trolleywheel and mount. Fig. 2, is a vertical sectional view of the mount. Fig. 3, is a front view of the trolley-wheel and its mount.

Similar letters of reference refer to simi-' lar parts throughout the several views.

The letter a indicates a trolley-wheel, of the usual shive-wheel type, provided with a hollow hub 12, supported rotatably upon a shaft 0. The hub b is perforated to form an oil-vent (Z, said oil-vent extending from the outer side of the hub in a diagonal direction downward toward the center of the shaft 0, and for the purpose of lubricating the said shaft.

The letter A indicates a trolley-wheel mount, which consists of a trolley-head 6 and a head-stock f.

The trolley-head e consists of a U-shaped, I

or fork-like muinbenflcomposed of a solid base 9 and two parallel, upwardly project ing bearihg-arms'lt.

The bearingarms )h are perforated at their upper ends, said perforations being disposed opposite one to the other, and form ing journal-bearings 6, wherein the extreme ends of the shaft 0 are journaled, respectively.

The base 9 of the trolley-tread is'perfo- Specification (if Letters Patent.

rated vertically and centrally to admit the hereinafter described journal-pin 9', upon which the trolley rotates. The extreme ends of the shaft 0 are journaled in the journalbearings 71 and said shaft supports the trol'-' ley-wheel a. The extreme ends of the shaft 0 project beyond the journal-bearings i, and are perforated to receive the .cotter-pinsm, respectively, whereby said shaft is prevented from lateral movement. The trolley-head is flat upon either side, for the purpose of presenting a flat bearing surface to two retain-e ing springs s, hereinafter described.

The head stock f consists of'a metallic, cone-shaped member, flattened upon two opposite sides, and inverted to place the larger end upward. The central portion of the head-stock f is perforated horizontally by a large slot t, for the purpose of reducing the weightof the stock, and to permit the placement of the journal-pin j. The upper portion of the stock f'is provided with a perthreaded perforation n, adapted to receive the ournal-pin j, as-shown. The journalpm 9' is provided'with external threads'u, throughout its lower portion, adapted to screw into the threaded perforation n of the head-stock f; and the upper portion isproportioned .to nicely fit into the vertical erforat'ionvprovided therefor in the base 0 l the "trolley-head e.

The journal-pin j is provided with a head 0 upon the lower end, adapted to seatitself firmly against the body of the stock, and is perforated at the upper and projecting end. to receive a cotter-pin 9, whereby the trqlley-head is'confined upon said journal-pin! The lower portion of the head-stock f is hollow perpendicularly, and adapted to receive the outer end of a trolley-pole w, upon which the trolley-mount is supported and. firmly attached by means'of a pin 0, which passes through opposite sides of the lower end of the head-stock and the trolley-pole, respectively. A broad, flat spring 8, wide at the upper end and tapering toward the bttom, is firmly attached by means of screws 9 to either flattened side of the head-stock, and is so positioned that the broad, u per end thereof, will project upward and ear against the flattened sides of the trolleyhead, respectively, as shown. The springs .9 are disposed opposite to each other, and are so adjusted that they bear firmly againstthe corresponding: sides I of the trolley-head,

Lara

thereby serving to hold the trolley-head and its wheels in perfect alinement with the head-stock, and incidentally in perfect alinement with a straight trolley-wire as, against which the trolley-pole holds said wheel.

The springs s are designed with proper nicely proportioned pressure exerted by the springs s, the trolley-wheel is at all times held in perfect alinement with the trolleywire it follows, and all dangeris avoided of said wheel crossing or jumping the wire, and. causing broken cross-wire and 5 V a rotatable trolley-head, and a fixed headother troubles incidentto such accidents,

The advantages claimed for my inven' tion, over similar devices used heretofore, consist 'in the simple, compact, and substantial structure of the mount; the nicely adjusted flexibility of the trolley-head, attained by reason of the peculiar structure thereof. t

What I claim as new and useful, and desire to secure by Letters Patent, is:

1. The combination with a rotatable trolley-head and trolley-wheel axle or shaft, with a head-stock, adapted to movably support said trolley-head, a journal-pin fixed centrally on the body of said head-stock and adapted to confine said trolley-head in movable connection with said head-stock, a pair of oppositely disposed springs attached to said head-stock, and adapted to bear upon opposite sides of said trolley-head, all substantially as described and for the purpose set forth.

mounted upon opposite sides of said headareas re 2'. In a'trolley-wheel mount, the combination of a rotatable trolley-head, said trolleyhead consisting of a base and two bearingarms; and journal-bearing in said bearingarlns, adapted to receive a trolley-wheel axle, or shaft, with ahead-stock adaptedto support said trolley-head upon its upper face, a journal-pin threaded centrally into and projecting upwardly fromthe upper face of said headstock, and adapted to confine said trolley-head in movable" connection with the head-stock, two opposing springs,

stock and projecting upwardly, and adapted to press against opposite sides of said trolley-head, and means of attaching saidheadstock upon the extreme end of a' trolley-pole, all substantially "as described and shown,

and for the purposes set forth.

3. Ina trolley-wheel mount,- consisting of stock, in movable connection with each other, means of attaching-said members together, a pair of opposing springs, fixed upon the respective sides of said head-stock and adapted 'to bear against the corresponding sides ofsaid trolley-head, a hollow, lower portion of said head-stock adapted to receive the end of a trolley-pole, means of attaching said head stock to a trolley-pole, and a trolley-wheel shaft journaled in, and supported by, said trolley-head, all substantially as described and shown, and for the pur poses set forth,

In testimony that I claim the foregoing as my own, I have affixed 'my signature hereto, in the presence of two Witnesses.
