CAR-AXLE BQX.

SPECIFICATION forming part of Letters Patent No. 375,221, dated December 20, 1887.

Applicaion filed September 21, 1885!. Serial No. 250,301. (No model.)

To allwhom it may concern.-

Be it known that I, STEPHENR. STINARD, of Pompton, in the county of Passaic and State of New Jersey, have invented a new and Improved Oar-Axle Box, of which the following is afull, clear, and exact description.

The present invention has for its object to i mprove the construction of the car-axle box for which Letters Patent No. 354,448 were granted me December 14:, 1886, and in such manner that waste of thelubricant will be avoided.

The invention consistsin fitting a tray having inclined or sloping side walls into the axle-box below the axle-journal, and whereby, while the setting oiled waste will, as before, be forced or crowded against the axle-journal, the lubricant will be retained in the tray, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a central longitudinal sectional elevation of my improved car-axle box, taken on the line 90 :0 of Fig. 2, and with the end of the car-axle shown in side view. Fig. 2 is a transverse section taken on the line y y of Fig. 1; and Fig. 3 is a perspective view of the oil-waste tray, drawn to a larger scale.

The journal (1 of the car-axle A bears on a brass, B, fittedat the top of the axle-box O, and the box has a dust-slide, D, at its inner end, and a drop-lid, E, at its outer end; and the box has lugs F, to receive the saddle-bar of the car-truck frame, all substantially as described in my prior patent aforesaid.

In my former patent the opposite sides of the axle-box are inclined inward toward a plate which is fitted onto lugs in the box and forms the bottom of an oil-waste cavi by, the side walls of which are formed by the inclined sides of the box, the object being to support oiled waste or other lubricant-absorbing material in such relation to the axle-journal that a settling or packing of the waste will force or crowd it all the more closely to the journal, which thus always receives proper lubrication to keep the axle and boxcool and in good condition. The only valid objection to this construction is that the oil is liable to leak'from the cotton waste or other absorbent and escape at the joints ofthe loose bottom plate with the adjacent walls of the axle-box. This objectionable feature is entirely obviated by the present improvement, which consists in 5 using a tray having inclined side walls to hold the waste, as next described. This oilwaste tray H has a bottom, I, which corresponds with the loose plate I of the former patent, and is in like manner provided with a transverse rib, J, which enters notches g,made in flanges G Gr on the opposite sides of the axle-box chamber, and on which flanges the tray H is supported. The engagement of the rib J with the flanged notches gprevents accidental endwise displacement of the tray, but allows removal of it whenever required. The opposite side walls, h h, of the tray are inclined toward the tray-bottom I. The front wall, h,

of the tray, is about theheight of the side walls, It, and the rear wall, h", of the tray is of like height, but has a concaved recess, h, which allows the tray to fit loosely beneath the axle-journal. It is obvious that while this tray, having inclined sides and with the ;5 oiled waste K therein, affords every advantage of the old construction with a loose bottom plate, as regards compulsory crowding of the waste to the axle-journal, it has the additional and important advantage of retaining the oil which is poured onto the waste to prevent loss of the oil and assure a much longer-continued lubrication of the axle-journal with a given quantity of oil or grease and with less attention on the part of railway em- '8 5 ploys.

The tray H may be made very cheaply by casting it in one piece of metal; or it may be shaped from sheet metal or made in any other approved way. 0

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

1. The combination, with a car-axle box and the axle, of a tray fitted in the box and having sloping or inclined side walls, substantially as shown and described, whereby settling oiled waste placed in the tray will be save the oil, and said tray having a rib or lugs entering notches of the axle-box,substantiall y as herein set forth.

forced to the axle-journal and the lubricant will be retained in the tray, as and for the purposes set Iorth.

2. The combination, with a car-axle box and 5 the axle, of a tray fitted in the box, and hav- \Vitnesses:

ing sloping or inclined side walls which force GEORGE WASHINGTON MICKENS, settling oiled waste to the axle-journal and l A'BRAM L. DEBOW.
