CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 448,130, dated March 10, 1891.

Application filed July 2, 1890. Serial No. 357,578. (No model.)

T0 to whom it may concern.-

Be it known that I, ILLIAM CROSS, residing at IVinnipeg, Manitoba, Canada, have invented a new and Improved Car'Axle Box, of which the following is a specification.

The invention is an improvement in the class of car-axle boxesin which the axle-journals rotate in contact with a liquid lubricant held in the bottom of the boxes.

The invention consists in the construction, arrangement, and combination of parts, as hereinafter described.

Figure 1 is a vertical longitudinal section of the axle-box. Fig. 2 is a horizontal section, the upper half of the view being taken on the plane of the top of the brass and the lower half having the brass removed; and Fig. is a vertical transverse section in two different planes, the left-hand portion being taken on line m a; and the right-hand portion being taken on line y y.

In the drawings the axle is reduced in diameter just outside the car-wheel for the space of about two and a half inches, and is then increased in diameter about one inch or a half an inch all around to form the journal A.

O is the axle-box, which upon the inner side is provided with a dirt-guard D, in the form of a packing held in the axle-box and embracing the narrow neck portion of the axle.

Bis a brass block, which is inserted between the top of the axle-box and the upper side of the journal. When this brass is inserted, it raises the axle-box, so that the dirt-guard and easing come up close to the smaller part of the axle. This causes as much of the journal as is larger than the axle at the dirt-guard to drop below the level of the opening in the casing, and as the bottom of the casing or box forms a tight oil-reservoir up to the level of the opening through which the neck of the axle passes it will be seen that the greater diameter of the journal A causes its periphery to dip down into permanent or continuous contact with the oil in the subjacent reservoir, thus receiving constant lubrication without waste and without fibrous packing.

E is a tallow-box formed upon. the top of the casing and having an outlet at the bottom arranged to discharge into the oil-reservoir below. The object of this is as follows: If the oil in the reservoir below becomes used up to the extent of failing to properly lubri- 1 eate the journal and heating ensues, this heating will melt the tallow ornormally solid lubricant in this box E, which will flow down into the oil-reservoir below and raise the level of the normally liquid oil to a renewal of perfeet contact with and lubrication of the journal.

In constructing the brass B it is formed with a right-angular arm or extension B which descends to the center of the journal and abuts against theend thereof. This center bearing or stop is held up against the end of the journal by a cross-bar F, Whose ends are driven into seats f, formed in the sides of the journal-box. This not only secures the brass in place, but it prevents the longitudinal vibration of the journal in the box.

The pendent portion or arm B of the brass B is tapered or cut away on its sides, as shown by dotted line in Fig. 3, thus leaving a space between its sides and the adjacent sides of the axle-box for passage of alubrieant escaping from the outlet of tallow-box E. Y Thus the melted tallow flowing down over the face of the arm of brass 13 upon the cross-bar F diverges, in part, laterally and enters the axle-box through the lateral passages formed as above described, while a portion flows over the front of the crossbar, and thus reaches the same place.

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

The combination, with the axle-journal, the axle-box, and its front cross-bar, of the bearing-block B, having its pendent front end tapered, thus forming side passages for thelubricant, as specified, and the tallow-box E, having abottom outlet located in front of said block and directly over the cross-bar, as and for the purpose specified.

VILLIAM GROSS.
