Description

Patented Feb. 6, 1923.
WILLIAM C. HARDEN, OF ODENVILLE, ALABAMA.
TROLLEY WHEEL.
Application led November 10, 1921.
To all whom t may concern:
Be it known that I, VILLIAM @new HARDEN, a citizen of the United States, residing at Odenville, in the county of St. Clair and State of Alabama, have invented a new and useful Trolley `Wheel, of which the following is a specification.
This invention relates to trolley wheels, pulleys or the like, and aims to provide novel means to insure lubrication of the wheel or pulley.
Another object of the invention is to provide a wheel or pulley having an oil chamber, means being provided to scoop the oil and direct the same to the bearing thereof.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawing:
Figure 1 is a sectional view taken on line 1-1 of Figure 3.
Figure 2 is a sectional view taken on line 2-2 of Figure 3.
Figure 3 is a sectional view taken on line 3 8 of Figure 1.
Referring to the drawing in detail, the device embodies sections 5 and 6, which sections are secured together as by means of the bolts 7, which pass through registering openings in the sections.
Each section is formed with a cut out portion 8, which cut out portions provide an oil containing chamber when the sections are brought together as shown by Figure 8 of the drawing.
The wheel is formed with a central opening 9 for mounting on an axle or shaft, the central opening being in communication with the oil chamber S, as through the pipes 10 which are disposed in spaced relation with each other and provided with curved extremities 11 which pick up quantities of oil contained in the oil chamberS and deliver the same to the shaft or axle on which the wheel is moving. As shown, a pair of these tubes are carried by each section of the wheel, the tubes of one section being Serial No. 514,354.
tion with the chambers 13 formed between the outer surfaces of the sections and the iianges 14 which are spaced therefrom, as clearly shown by Figure 3 0f the drawing.
Upenings l5 are provided, which openings register with the opening 9 of the wheel to accommodate the supporting shaft associated with the wheel. Opening 15 should be somewhat larger than opening 9.
From the foregoing it will be seen that as the wheel is moved from a stationary position, the initial movement or rotation of the pulley causing the pipes 1() and l1 to scoop up quantities of the fluid and deliver the same to the central opening 9 to' lubricate the shaft positioned therein. The waste oil from shaft flows into chamber 13, and thence through tubes 12 into chamber 8.
In order that oil may be supplied to the chamber 8, a filling opening 16 is provided in one of the sections, the opening being normally closed by any suitable means not shown. K
Having thus described the invention, what lis claimed as new is A wheel construction embodying opposed sections, each section having a. cut out portion providing an oil chamber, when the sections are brought together, each of the sections having a central opening, curved pipes having their inner ends disposed adjacent to the central opening and having their outer ends positioned in the oil chamber, said wheel having lateral chambers, pipes providing communication between the lateral chambers and oil chambers, and said curved pipes adapted to deliver quantities of oil to the central opening when the wheel is moved from its inactive position to its active position.
In testimony that l claim the foregoing as my own, I have hereto aiiixed my. signature in the presence of two witnesses.
