CAR WHEEL.

Specification of Letters Yatent.

Patented Apr. 4, 1922 Application filed November 9, 1918. Serial No. 261,819.

To all whom it may concern.

Be it known that I, WILLIAM F. SGHERER, a citizen of the United States of America, residing at Weston, in the county of Campbell and State of Wyoming, have invented new and useful Improvements in Car lVheels, of which the following is a specification.

The object of the invention is to provide a simple, relatively inexpensive and efficient car wheel, suitable for railway and street car use, in which freedom of movement forwardly and rearwardly of the wheel proper is permitted independently of the axle, wherein there is provision for ample lubrication, and in which means are employed for excluding dust and dirt from the journal, to the end that the durability and relative efficiency of the structure may be increased while maintaining the cost of manufacture within reasonable limits.

Further objects and advantages will appear in the following description, it being understood that changes in form and proportion may be resorted to within the scope of the claims without departing from the spirit of the invention.

In the drawings:

Figure 1 is a side view of a wheel and axle showing a preferred embodiment of the invention,

Figure 2 is a similar view partly in section to show the construction of the bearing or journal,

Figure 3 is a detail view of the retaining ring or collar.

In the illustrated embodiment of the invention, the wheel 10 is constructed independently of the axle 11 and is mounted upon a reduced portion or spindle 12 of the latter for free movement forwardly and rearwardly, or for independent rotation in either direction, said wheel proper being provided in its bore with lubricant grooves 18, and having an inwardly extending sleeve 1 1 terminated in an outturned flange 15. Said sleeve is enclosed within a casing 16 which forms a lubricant cup or chamber and is rigidly or fixedly secured in any suitable manner to the body portion of the axle and is provided at its outer end with an inturned flange 17 which takes into the annular groove or cavity formed around the sleeve 14 between the facing surfaces of the wheel proper and the outturned flange of said sleeve, whereby oil, grease or other lubricating material placed in the casing will be held in such position that the wheel practically runs in oil or lubricant, the lower portion of the sleeve being submerged so that the lubricating material is carried entirely around the journal and insures a minimum of friction and wear in the operation of the device.

The outward displacement of the wheel is prevented by a split ring or collar 18 which receives the outwardly projecting portion of the spindle of the axle and fits in an annular seat 19 formed therein, said ring or collar and the outer portion of the spindle, together with the hub 20 of the wheel being enclosed within a cap 21 which is removably fitted upon said hub and is designed to turn with the wheel.

Obviously, the lubricating material disposed in the casing enclosing the inwardly projecting sleeve formed on and carried by the wheel proper, is caused to work through the hearing or journal of the wheel proper to the outer extremity of the hub, whereas the casing on the inner side of the wheel and the cap carried by the hub serve to exclude dust and dirt from the bearing surfaces and maintain a suitable, practical frictionless working condition of the movable contacting members of the structure.

Also it will be obvious from the foregoing description that a wheel of the construction indicated may be produced at a reduced cost as compared with those now in general use which are formed on or in connection with the axle by which the opposite wheels of a car are connected, and moreover, the removal of a worn or damaged wheel may be accomplished with facility, it being necessary simply to displace the cap and remove the retaining ring or collar in order that the wheel proper may be exposed.

Obviously, the complete removal of the wheel can be accomplished only by also dis-l placing the casing, which to facilitate such operation, is of sectional construction as indicated.

' What is claimed is:

The combination with an axle having a reduced spindle portion, of a wheel having an outwardly extending hub portion and an inwardly extending exteriorly channelled sleeve, a lubricant containing casing carried b the axle to enclose said sleeve and provlded at its inner end with a lubricant retaining flange in contact with the bottom of the channel in said sleeve, a ring or collar engaging the spindle beyond the outer end of said hub consisting of a split Washer and an embracing spring retainer, and a lubricant retaining cap carried by the hub and 10 housing the extremity of the spindle and said ring or collar.

In testimony whereof I affix m signature.

WILLIAM F. SC ERER.
