IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 156,767, dated November 10, 1874; application filed September 16,1874.

CASE 0.

To all whom it may concern:

Be it known that I, JOHN M. BROSIUS, of Richmond, in the county of Henrico and State of Virginia, have invented a new and Improved Oar-Axle Box and Lubricator; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure l is a longitudinal sectional elevation Figs. 2 and 3, front and rear end views, and Fig. 4 a cross-section in detail.

The invention relates generally to the axleboxes of car-trucks; and consists in several improvements, which will first be fully described, and then pointed out in the claims.

A represents a car-axle box, and B the journal that works therein.

First, I make the journal-gate E with excisions e e at the lower end, and place in the guidegroove E the triangular blocks or inclined strips 0 6. By this construction the gate does not require to be held by handwedge or other device, but will restin position until the journal is inserted in the box, and then rise as the journal is pressed inward, a sufficiency of the bottom being still left open to allow dust or dirt to escape in the usual manner.

Second, I form a box or projecting plate, F,

on the inside of axle-box, and at the end where the journal enters, so as to prevent the lubricant from being splashed out at the joint f. In old boxes I shall make it of sheet metal, fasten it by screws f f, and in' new ones I preferably cast it with the box. After a careful trial I find that it saves no inconsiderable portion of the lubricant, while it avoids the accumulation of oil at the joint, and the consequent gathering thereto of dirt. I

Third, I make an annular recess or groove, a, in axle and near the journal, for the purpose of receiving an elastic ring, I, that serves to form a packing to prevent the escape of the lubricant, and to exclude grit and dirt from working into the axle-box.

Fourth, I make the piece that is intended to hold the lubricating fabric J up to the journal of a single longitudinal metallic platespring K, so that it may be readily bent to accommodate itself to any inner conformation of axle-box, be easily fastened by the screw 70 in front, and be prevented from lateral play by a simple plate or cross-bar, k, which may have turned-up ends. This is not only applicable to old as well as new boxes, and very efficient for the purpose intended, but is comparatively cheap and easily adjusted from the bottom by a set-screw, k so as to accommothe lugs 10 k of the spring, so that the fabric will automatically adjust itself to and bear always along the whole length of the journal.

Having thus described my invention, what Iclaim as new is v 1. The combination, with axle-box, of a journal-gate, E, having excisions e e, and the guidegroove E, having inclined strips 6 c placed in the lower end, as and for the purpose set forth.

2. The plate F, projecting inwardly from the rear of axle-box, as and for the purpose specified.

3. The combination, with an axle having the annular recess or groove to, of the elastic ring I, as and for the purpose set forth.

4. The eombinatiol'l, with axle-box, of a device to hold the lubricating fabric to the journal, consisting of the plate-spring K, placed longitudinally on the bottom of the box, fastened at the outer end, and the cross-bar k as shown and described.

5. The combination, with lubricating fabric J, of the slotted holder J and guide-plate J as and for the purpose described.

6. The combination, with spring-band K, of a pivoted fabric-holder, J as and for the pur pose specified.
