SPECIFICATION forming part of Letters Patent No. 680,567, dated August 13, 1901. Application filed November 22,1900. Serial No. 37,332. (No model.)
To aZZ whom it may concern.-
Be it known that I, WILLIAM C. COTTRELL,
and parts and combinations of the same, as
will be fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is representedin the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.
Figure 1 is a cross-section of the improvement, and Fig. 2 is a side elevation of the same.
The wheel proper consists, essentially, of an outer section A, an inner section B, secured to the axle C, and plates D, extending over the joint between the outer and inner wheelsections A and B, the plates being secured by bolts E to the outer Wheel-section A, and said plates having annular inner projections D,
. forming with the grooved peripheral surface of the inner wheelsection B a ball-race containing balls F. By the arrangement described the outer wheel-section A is free to revolve independently of the inner section B,and by the use of the ball-bearings a very easy running of the section A isobtained. The outer Wheel-section A is formed on its periphery with the usual groove for engaging the trolley-Wire.
The axle 0 extends with its outer ends into ball-cups G, screwed into the sides H H of the yoke H, adapted to be secured to the outer end of the trolley-pole in any suitable manner. The section H is preferably hinged at H and is normally locked in position by a pin 11*, which when withdrawn permits of swinging the side H outward for removal of the axle O and the wheel carried thereby in case repairs are necessary.
Each of the ball-cups G is formed at the inside with an annular groove G for containing balls I, also engaging an annular shoulder O on the axle C, said shoulder O and groove G forming a ball-race for the balls I. By the arrangement described the axle C is mounted on ball-bearings to insure a very easy running of the axle and consequently of the inner Wheel-section B.
In order to hold the balls I in position in the cups G, I employ retaining-rings J, fitted in the inner ends of the cups and held in position by spring-rings K, fitting in the recesses in the wall of the cup, as is plainly indicated in Fig. 1. Set-screws L screw in the sides H H to secure the cups G in position after the cups have been adjustedthat is, screwed inward or outward to hold the balls I in proper position in the ball-races.
In order to prevent electricity from passing through the usual ball-bearings and the axle ball-bearings, I provide brushes N, secured to the sides H H and engaging the outer faces of the plates D, so that the electricity passes directly from the outer wheel-section A to the plates D and by the brushes N to the yoke H, and then by the pole to the polehead and motors of the car on which the trolley-wheel is used.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A wheel comprising inner and outer sections independently revoluble, and annular plates secured to the side faces of one section and projecting beyond the same into engagement with the side faces of the other section to hold the two sections engaged, said plateshaving annular projections extending inwardly between the sections of the wheel to form a bearing-surface for the one upon the other.
2. A wheel, comprising inner and outer sections independently revoluble, annular plates secured to the side faces of one section and projecting beyond the same into engagement with the side faces of the other section to hold name to thisspecification in the presence of the tvivo sections engaged, saaid plates Saving two subscribing Witnesses. i annu ar projections exten ing inwar y e- 1 tween the sections to form a bearing-surface, WILLIAM COTl BELL 5 and bearing-ba1ls arranged to run on said Witnesses:
