BOX.

SPECIFICATION forming part of Letters Patent No. 578,949, dated March 16, 1897.

Application filed August 2 9, 1 8 9 6 To all whom it may concern:

Be it known that I, JOHN IV. SKILTON, a citi- Zen of the United States, residing at Miami, in the county of Dade, State of Florida, have invented certain new and useful Improvements in Axle-Boxes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and 1o useful improvements in axle-boxes; and it has for its object, among others, to improve upon this class of devices in such a manner that the axle will be thoroughly lubricated, so as to run for a great length of time without being again oiled. I provide against the waste of the lubricant and employ Wicks, preferably of sponge, that serve by capillary attraction to supply the oil to the bearing and also to keep the journal thoroughly clean.

supported upon springs and having openings for the passage of the wicks. The inner end of the casing is bored out larger than the axle and deep enough to receive packing and a follower, which is drawn to place and held adjustably by bolts or rods. The wooden box within the casing is provided with a felt strip at the back end and also along its upper face, which. corresponds with and lits the 3o under side of the axle, the box being held in position by springs bearing against the outer end thereof and the felt strip serving also as a means of keeping the axle supplied with oil.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention in this instance resides in the peculiar combinations and the construe tion, arrangement, and adaptation of parts, all as more fullyhereinafter described, shown in the drawings, and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a central vertical longitudinal section showing the improved axle-box. Fig. 2 is a vertical cross-section on the line 2 2 of Serial No. 604,275. (No model.)

Fig. l, looking in the direction of the arrows. Fig. 3 is a view looking at the inner end of the follower, which is removed. Fig. 4 is an end elevation of the wooden box removed.

Like letters of reference indicate like parts 5 5 throughout the several views.

Referring now to the details of the drawings by letter, A designates the outer casing, which is similar to the standardbox now in general use except as hereinafter specified. 6o Instead of the usual hinged door at the outer end this end is closed by the plate or cover B, which is secured to the end of the casing by screws C or analogous means. The inner end of this casing is adapted to receive the flange D of the follower-plate E, as shown in Fig. l.

F is packing of any suitable character, disposed between the inner end of the flange of the follower-plate and the inwardly-extend- 7o ing annular flange G of the casing, the follower-plate having a iange e, which bears against the inner end of the casing, as indicated. 'lhe follower-plate is drawn in and there held by means of the rods H, which pass'through holes h in the iange e of the said plate and receive nuts upon their other ends, which pass through the end plate B, as shown. By this means the packing can Abe compressed as may be required.

The bore of the follower-plate fits snugly around the axle, as shown, and the packing also lits snugly about the axle and prevents waste of the oil or lubricant at the inner end of the casing. In fact, the construction is such that there can be no waste at any point.

Upon the upper side of the axle within the casing is the bearing-block L and the wedgeblock J, of usual construction and mode of operation. 9o

K is a wooden box supported upon elliptic springs L', only one of which is shown, which rest upon the bottom of the casing, as shown, their ends being free for movement and their arched portions bearing against the under side of said box. This box is concaved upon its upper face to fit the curvature of the axle, and it has a plurality of channels M for the passage of the wicks N, which are by preference of sponge, and which bear against the roo under side of the axle and serve to conduct the oil thereto and also to keep the axle at all times thoroughly clean.

O is a thick piece of felt arranged at the inner end of this box and its upper edge shaped to fit the axle against which it bears. This felt is kept in position by the springs P, (only one being shown,) which are arranged at the front end of the box and between the same and the front end or plate B, and are preferably entered in holes Q in the front end of the box, so as to prevent their displacement. The number of springs employed for this purpose may be varied.

R is the axle.

Modiiieations in the details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages. A

NV hat is claimed as new isl. The combination of the easing, the box therein with passages, the springs pressing upon the under side of the box, means interposed between the outer end of the box and the inner face of the end of the casing and the wicks in said passages and bearing against the under side of the axle, as set forth.

2. The combination of the casing, the box therein and having vertical passages, the

springs beneath the box, and means acting on the outer end of the box to press its inner end against said packing, the wicks located in said passages, and the packing at the inner vend of the box, as set forth.

3. The combination of the casing, the box, the springs beneath the same, the wicks, the felt strip at the inner end of the box, and the springs acting against the outer end of the box, substantially as and for the purpose specified.

4. The combination, with the casing having a flange, and the follower-plate having an inwardly-extending flange, of the packing between said flanges, the box within the casing, the springs acting on the outer end of said box and the wicks of sponge passed through said box, substantially as specified.

5. The combination, with the box having vertical passages, and the wicks passed therethrough, of the springs bearing upon. the under side of said box, the felt strip at the inner end of the box, and the springs between the outer end of the box and the inner face of the end plate, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.

J OHN W. SKILTON.
