TROLLEY.

SPECIFICATION forming part of Letters Patent No. 600,633, dated March 15, 1898.

Application filed November 4,1896. erial No. 611,013. (No model.)

To all whom it may concern:

Be it known that I, JOHN CLAYTON, a citizen of the United States, residing at Ouyahoga Falls, in the county of Summit and State of Ohio, have invented certain new and use ful Improvements in Trolleys; 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 to make and use the same.

My invention relates to electric trolleywheels.

I-Ieretofore considerable difliculty has been experienced in using trolley-wheels, owing to the fact that frequent lubrication was necessary in order that the wheel might run smoothly. Another difficulty has also been experienced, as the trolley-wire is liable to jump the trolley-wheel when the car is moving rapidly or going around a curve.

The object of my invention is to provide a novel form of trolley-wheel which will be selflubricating for a comparatively long period of time, thereby doing away with the expenditure of time and labor.

A further object is to provide improved means adapted to prevent the trolley-wire from jumping the wheel.

Having these objects in view, the invention consists in the combination, with a trolleywheel, of a hollow bearing therefor, which is adapted to hold a lubricant and is provided with outlets, so that the lubricant will be delivered to the bearing-surface of the wheel as the latter revolves. V

The invention further consists in certain improved guards adapted to prevent the trolley-wire from jumping the wheel; and it further consists of certain other improved features and novel combination of parts appearing more fully hereinafter.

In the accompanying drawings, Figure 1 is a side elevation, Fig. 2 an end view, Fig. 3, a cross-sectional view, and Fig. 4 a detail View, of the hollow bearing for the wheel, the latter being removed, said view disclosing one pair of lubricating grooves.

The numerals 1 and 2 designateduplicate sections or halves of the head, and these clasp around and are secured to the trolley-pole 3. The sections of this head are provided with hollow bearing-sections i and 5, said sections being form ed integral with the respective sections of the head. Each bearing-section is provided with opposite lubricating- grooves 6 and 7, which slant downwardly. These grooves are deepest at the inner edge of the section, wherea semicircular hole 8is formed, which leads into the interior of the section. It will thus be observed that when the bearing-sections abut on each other there are provided two circular holes 9 and 10, through which the lubricant contained within the bearing-sections can find its way out into the grooves.

The numeral 11 designates the trolleywheel, which is snugly yet easily received on the bearing-sections. At 12 is shown a bolt which passes through the bearing-sections from side to side of the headand is provided with a nut 13 on its ends. The lubricant employed should be solid or substantially so, and it is introduced in the bearing-sections, the latter projected into the trolley-wheel, and then the parts are clamped together by the bolt and nut. As the wheel revolves the lubricant passes out through one of the circular openings and into the inclined grooves that lead therefrom, so that said lubricant is distributed over the entire width of the bearingsurface of the trolley-wheel. Of course it is obvious that as many of the openings and lubricating grooves could be employed as found desirable; but I find that two sets are generally sufiicient, and hence have only spoken of that number. The capacity of the bearing-sections being quite great, the wheel will be self-lubricating for a number of days.

I will now proceed to the description of the means adapted to retain the trolley-wire on the wheel. Connected to each section of the head there is a curved or arc-shaped guard 14:, and this guard lies immediately outside the faces of the wheel and projects up above the periphery thereof. It can be made of any desired width and is well adapted to guiide the trolley back into the wheel should it jump from the latter.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with head sections adapted for connection to the trolley-pole, of hollow bearingsections connected to said munication with the interior of the bearing-v sections, and a trolley-wheel mounted on said bearing-sections.

3. The combination with head sections adapted for connection to the trolley-pole, of

hollow bearing-sections connected thereto and projecting inwardly and meeting, said sections being adapted to contain the lubricant, each bearing-section being provided with an inclined lubricating-groove which leads from the edge of the section laterally, said grooves being disposed in sets which meet at the edges of the bearing-sections, a trolley-Wheel mounted on said bearing-sections, and means for holding the head-sections together.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN CLAYTON.
