UNITED STATES PATENT OFFICE;

WILLIAM II. IfIoE'LL, or GRANDCANE, LOUISIANA.

LUBRICATING-AXLE.

SPECIFICATION forming* part Of Leiters Patent N0. 646,830, dated April 3, 19O.

Application filed 001701381' 23, 1899. Serial. No. 734,507. (N0 model.)

T all whom t may concern:

Be it known that l, WILLIAM H. HoELL, a citizen of the United States, residing at Grandcane, in the parish of De Soto and State. of

Louisiana, have invented new and usefulA Improvements in Vehicle-Axles, gSkeins, and

Boxes, of .which the following is a specifica# ,features and in the construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claims followingV the description, reference being had to the accompanying drawings, forming apart of this speciiicatiomwherein- Figure 1 is a vertical longitudinal sectional view of my improved axle spindle, skein, and box. Fig. 2 is a bottom plan view of the axlespindle, and Fig.-3 is a similar view of the axle-skein. y

Referring to the drawings, the numeral -1 indicates the axle, 2, the axle-spindle; the axle-skein, and 4 the axle-box.v The axlespindle is turned down or made of reduced diameter between its ends, as indicated at 5, to form achamber for the reception of an oilpad 6. The oil-pad 6 may consist of a strip of felt or other suitable fibrous material, and is conveniently` attached in place by wire loops or bands '7 twisted about the spindle and pad. The u nreduced ends of the spindle are exteriorly screw-threaded, as indicated at 8 and 9, and over said threaded portions is screwed theaxle-skein-S, which is interiorly threaded at its ends for the purpose, as indicated at 10 and 11. In order to prevent the axle-skein from accidentally becoming unscrewed from the spindle, I form a threaded hole 12 (shown in dotted lines) in the unreL duced end 8 and a corresponding perforation 13 in the end of the axle-skein, said perforation and hole being arranged to register with each other when the skein is fully screwed up in place on the spindle, after which a machine-screw 14 is screwed through the perforation into the threaded hole and effectually prevents the skein from turning on the spindle. As shown, the oil-pad 6 is secured to the under side of the spindle,v so that the oil, which is supplied to the chamber 15 through perforations 16, formed in the upper side ofthe skein, runs down by gravity to the pad and saturates the latter. Elongated slits or slots 17 are 'formed in the under side.

be found amply sufficient to keep the parts effectively lubricated, owing to the thorough manner in which the parts are protected and dust and the like excluded by the means which I will now describe.

Formed externally `on the inner end of the axle-skein is a collar 18, provided with an outwardly-projecting annular flange 19, that is concentric with the skein and the internal diameter of which is slightly greaterthan the external diameter of the skein, thereby forming an annular groove 2O between the skein and flange for the purpose presently made apparent. The axle-box 4 is rotatably fitted .over the skein, and at its inner end is provided with two concentric inwardly-extending flanged collars, respectively numbered 21 and 22 in the drawings, an annular groove 23 being formed between said flanged collars, in the bottom of which is disposed a packingring 24, of leather or other suitable material. When the axle-box is in place on the skein, the inner anged collar 2l fits in the groove 20, and the iianged collar 19 tits in the groove 23, between the

flanged collars

21 and 22. The outer end of the axle-box is slightly reduced in diameter internally, as at 25. By the means described oil is prevented from escaping between the axle skein and box and dirt, sand, and the like are eectually exeluded.

The threaded end 9 of the axle-spindle is extended beyond the end of the axle-skein, and the latter is extended slightly beyond the end of the axle-box. When the parts have been assembled in place, a carriage-nut 26 is IOO screwed over the end 0 of the spindle. The nut is provided with an internal annular shoulder 27, that bears against the end of the skein, and with an annular flange 2S, that fits over the end of the skein. If preferred, a washer 20 may be fitted against the shoulder 27. In this manner dirt, sand, and the like are prevented from gaining entrance at the outer end ot' the axle.

The entire device constructed as above described is extremely simple and comprises but few parts, which may be quickly taken apart for cleaning, oiling, or the like and as quickly assembled again. Owing to the improved manner of applying the lubricant, the oil need only be replenished at long intervals, thereby effecting an economy in both time and labor and in the consumption of the lubricant. No wear occurs to the axle-spindle, it being entirely taken up by the axle-skein, and when the latter becomes suiiiciently worn to cause the parts to operate loosely the skein can be readily removed and replaced by a new one.

A groove 30, rectangular in cross-section, is preferably formed in the under side of the inner end of the axle-skein. This is for the purpose ot receiving a clip-plate that is used in connection with an axle-clip when a wooden cap-piece is fitted to the upper side of the axle, the clip-plate and axle-clip operating to clamp the wooden cap-piece on the axle.

Having described my invention, what I claim isl. The combination with a metallic axlespindle reduced between its endsl to form an annular oil-chamber, of an axle-skein fitted over the enlarged ends of the spindle and provided with elongated slits in its under side through which the oil is fed by gravity, an oilpad disposed in said chamber between the spindle and axle-skein and over said slits, said pad being clamped on the spindle, and

means for locking the axle-skein on the spin# dle to prevent the former from turning independently of the latter, substantially as described.

2. The combination with a metallic axlespindle reduced between its ends to form an annular oil-chamber, of an axle-skein fitted over the enlarged ends of the spindle and provided with elongated slits in its under side through which the oil is fed by gravity, and provided on its upper side with oil-feed openings, a fibrous oil-pad disposed longitudinally in the bottom of said chamber between the spindle and axle-skein and over said slits, attaching-'bands clamped about the pad and spindle, and means for locking the axle-skein on the spindle to prevent the former from turning independently of the latter, substantialiy as described.

3. The combination with a 'metallic axlespindle reduced between its ends to form an annular oil-chamber, ofA an axle-skein fitted over the enlarged ends ofthe spindle and provided with elongated slits in its under side through which the oil is fed by gravity and provided on its upper side with oil-feed openings, an oil-pad disposed longitudinally in the bottom of said chamber between the spindle and axle-skeinv and over said slits, Wires tightly encircling said pad and spindle and secured together at their ends, and a screwpassing through the inner end of the axleskein and engaging a socket at theinner enlarged end of the spindle, substantially as described.

In testimony whereof I have hereunto set my hand in presence ot' two subscribing witnesses.

WILLIAM II. IIOELL.
