TROLLEY-WHEEL.

Specification of Letters Patent. Y Patented Apr. 11, 1916.

Application filed February 16, 1915. Serial No, 8,665.

To all whom it may concern:

I citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Trolley-Wheels, of which the following is a specification.

This invention relates to improvements in trolley wheels.

In carrying out my invention it is my purpose to provide a frame of cast metal orthe like which shall provide side members as well as the bearing for a copper or similar conducting ring which contacts with the feed wire of a trolley system.

Another object of the invention is to provide a device of this character wherein a conducting ring of comparatively soft material shall be removably arranged upon and supported upon a substantially hardened frame and rotatable upon the said frame, whereby worn rings or conducting members will be readily attached to or removed from the support.

Another object of the invention is to provide a device of this character which shall obviate the necessity of entirely disposing with the trolley wheel when the copper or conducting portion thereof has been worn out.

lVith the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

In the drawings: Figure 1 is a side elevation of a trolley wheel constructed in accordance with my invention, Fig. 2 is a similar view looking toward the opposite side of the wheel, Fig. 3 is a sectional view approximately on the line 33 of Fig. 1, Fig. 4 is a sectional view approximately on the line 4-4 of Fig. 3, Fig. 5 is a perspective view of one of the side or ring supporting members, Fig. 6 is a similar view of the co-acting side, and Fig.7 is a perspective view of the ring or conducting member.

Referring now to the drawings in detail, the numeral 1 designates my improved trolley wheel in its entirety. The wheel includes two side members indicated by the numerals 2 and 3 respectively. Each of the members 2 and 3 is provided with a peripheral annular portion 4, and the inner edge of each of said portions 4 is beveled out;

wardly, as at 5, and also the inner faces of the said portions 4 are beveled or inclined from their inner edges 5 toward their outer edge. A plurality. of spokes 6 connect the annular flanges 4 with a central, preferably annular member'7. The spokes 6 of the side member 2 extend-over the inner face of the annular member 7 thereof, and are provided with fingers 9 which project' within the bore of said portion 7. The portions projecting beyond the inner face of the member 7 of the said section 2 provide what I will term lugs 10, and the said members 7 as well as each of the lugs 10 is provided with alining or registering openings 11.

The second or co-acting member 3 also has its spokes 6 extending inwardly from its central portion 7, the said spokes being connected with the hub 11 which extends inwardly and centrally from the member 7. The outer end of the hub 11 is provided with a plurality of depressions or slots 12 co-inciding in number and adapted to receive the fingers 9 provided upon the spokes 10 of the member 2. The enlarged inner portions of the spokes 6 of the member 3 extend laterally and longitudinally from the flange 7 terminating in straight shoulders 13 that are disposed approximately at the terminals of the slots or grooves 12 and the said shoulders 13 are provided with threaded openings 14 which co-incide with the openings 10 in the spokes 6 of the member 2, while securing members, preferably in the nature of threaded elements 15 pass through the openings 11 and within the threaded shoulders 13 and secure the sections 2 and 3 in locked position.

The outer edges of the projecting or later- ..rrrc. I

ally extending portions of the spokes 6 of the member 3 are rounded to receive the inner edge of a ring or annulus 16. This ring member 16 is preferably constructed of copper and has its outer periphery formed with an annular depression 17, while its outer edges are preferably beveled, as at 18, to be snugly received by the angular portions 5 0f the flanges of the side members 2 and 3. One or both of the sides of the ring 16 is formed with one or more lugs or extensions 19 which are adapted to contact with the spokes of one of the sides of the device to retain the said ring against rotation, or in other words to cause the said ring 16 to rotate with the removable sides therefor. The hub of the section 3 is provided with a cylindrical bore which may have, and preferably has, acopper lining 20, which provides a bearing for the bolt or shaft which passes through the arms in the bifurcated end or harp of the trolley pole.

' From'the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what I claim is:

In a trolley wheel, a cylindrical hub provided with slots in its periphery, a pair of side members, including spokes and enlarged at their inner extremities, the enlargements of the spokes of one member being secured to said hub while the enlargements of the spokes of the opposite side member are provided with tongues that enter the hub slots, a grooved ring frictionally held between said members and having its inner surface resting on the enlargements of said spokes, and screws securing the enlargements of the spokes of one member to the enlargements of the spokes of the opposite member.

In testimony whereof I hereto aflix my signature in presence of two witnesses.
