SPECIFICATION forming part of Letters Patent No. 701,085, dated May 27, 1902.
Application filed January 29, 1902. Serial No. 911706. (No model.)
To all whom it may concern:
Be it known that 1, JAMES PRESTON, a citi zen'of the United States, residing at J oliet, in the county of \Vill and State of Illinois, have invented certain new and useful Improvements in Trolley-\Vheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to trolley-wheels, and particularly to the harps in which such wheels are held.
The object of the invention is to provide efficient means for holding such wheels in the bearings of the harp and for effecting a quick insertion or removal of the wheel therefrom. This object is attained by the use of a harp having arms hinged together and a sleeve supported by a jam-nut to clamp the arms to the wheel held between the same.
In the accompanying drawings, Figure 1 is a front elevation of an embodiment of my invention. Fig. 2 is aside elevation thereof. Fig. 3 is a central longitudinal section.
Referring specifically to the drawings, the trolley-harp comprises a stem 6, which is provided with two arms 6 and 6*, between which the wheel 7 is clamped and held to rotate. The arm 6 is integral or rigid with the stem and is provided with a lengthwise slot 8, in
which is pivoted by a pin 9 the end 10 of the arm 6", whereby the arm 6 is hinged and may be turned out to permit the insertion or removal of the wheel. The arms are clamped and locked by a sliding sleeve 11, which is flared or shaped to extend over or beyond the pivot 9 and engages the arms to bind the same together, The sleeve is retained by a jam-nut 12 on the threaded portion 12 of the stem.
The wheel is preferably cast or made in a single piece without an axle, and bearings are formed by cavities 13 in the wheel, which are shaped to receive the cones 14, secured to the arms, as by screws 15. Instead of cones ball or other antifriction bearings may be used.
Bythe construction herein shown axles and bushings are dispensed with, and the sleeveclamping arrangement permits ready removing of the wheel by unscrewing the jam-nut and lowering the sleeve below the junction of the arms.
What I claim is- The combination with a trolley-wheel, of a harp having hinged arms, a stem rigid with one of said arms, a sliding tapered sleeve on the stem engaging the arm to clamp the wheel therebetween, and a jam-nut on the stem binding the sleeve.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES PRESTON.
