LUBRICA'IOR FOR VEHICLE-WHEELS.

Specification of Letters Patent.

Patented Oct. 14, 1913.

Application filed April 19, 1912. Serial No. 691,949.

To all whom it may concern:

Be it known that I, Lr'ioiv DAMoURs, a subject of the King of Great Britain, residing at Trois Pistoles, Province of Quebec, Canada, have invented certain new and useful Improvements in Lubricators for VehicleWVheels; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will on able others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to lubricator for vehicle wheels.

In order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a central, vertical, cross section through a wheel hub, showing the invention applied; Fig. 2 is a fragmentary view showing the invention on an enlarged scale; and Fig. 8 is an enlarged elevation of the lubricating tube, removed.

In order to deliver lubricant from the chamber 6 to the wheel axle, a threaded bore is provided through the sleeve 5 to removably receive a small tube 9 provided with a plurality of perforations 10 and having an annular shoulder 11 against which is seated the lower end of a coil spring 12. The tube 9 does not extend to the shell 4, but has its upper end a short distance therefrom, within the chamber 6. Thus, there may be relative movement between the shell 4 and sleeve 5 without injury to the small sleeve 9. The upper end of this spring is connected to an absorbent wick 13 which becomes saturated with lubricant and feeds the same, by capillarity, to the axle. The wick 13 becomes saturated with the lubricant which enters the casing 9 through the perforations 10. As the lubricant enters the wick it will flow downwardly by force of gravity. As the wick becomes more and more saturated the lubricant will work farther and farther down until it reaches the axle. When the wick becomes completely saturated there will be a steady flow of oil to the axle. When the vehicle is not in use this flow will be prevented by the engagement of the end of the wick with the axle. But when the vehicle is in use the wheel revolving around the axle creates a continuous wiping effect on the lower end of the wick and greatly aids the capillary action thereof. In order to move the wick downward as it wears off, a screw plug 14 is threaded into the upper end of the tube 9. This plug engages the end of the spring. By turning the plug 14, the spring may be more or less compressed, and the wick correspondingly lowered, as will be clear on reference to Fig. 2. The coil spring 12 acts to keep the wick 13 extended longitudinally so as to prevent any bunching thereof, thus insuring the wick being properly lowered when the plug 14 is screwed in.

It is thought that the operation and use of the invention will be clear from the preceding detailed description.

Changes may be made in the construction, arrangement. and disposition of the several parts of the invention without in any way departing from the field and scope of the same, and it is meant to include all such within this application wherein only preferred forms have been disclosed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with a wheel, a sleeve provided with a bore, a shell mounted thereon and spaced therefrom to form a lubricant chamber, a perforated tube mounted in said bore and extending partially across the lubricant chamber toward said shell, a wick in said tube, means for keeping said wick extended, and means for regulating said wick extending means.

2. In combination with a Wheel, a sleeve provided with a bore, a shell mounted thereon and spaced therefrom to form a lubri- In witness whereof I have hereunto set my hand in the presence of two Witnesses.

cant chamber, a perforated tube mounted in said bore and extending partially across the lubricant chamber toward said shell, a Wick in said tube, a coil spring Within said tube and embedded in said Wick, and a plug threaded into one end of said tube and hearing against said spring.
