IMPROVEMENT IN CAR-AXLE BOXES.

Specication forming part of Letters Patent No. 178,723, dated J une 13, 1876; application filed December 6, 1875.

To all whom it muy concern:

Be it known that I, JOHN M. BRosIUs, of Richmond, in the county of Henricoand State of Virginia, have invented a new and Iniproved ltailway Oar Truck and Box; 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- Figures l and 3 are transverse vertical sections; Figs. 2 and 4., plan views.r

The invention consists in extending out the end of the upper section of axle-box, and making this extension detachable, so as to furnish convenient access to the space within and allow the brass to be replaced; in applying to one side of box an inclined spout, and making an excision on side face of brass, to allow the lubricant to be poured into the box, so as to ,easily reach the packing, and also the insertion of packing; in the employment of shouldered standards on the corners of box to support the brass above the bottom and allow ample space for the packing; in using two overlapping adjustable wedges in each box for bringing the'brasses, as they wear, in proper juxtapostion to the journals; and in making the bottom section in one piece, and with a median recess, to envelop half the two journals, so as to hold the axle more steadily and prevent deflection.

A A represent a car-truck, having the inner cross-pieces c c secured to the outer pieces A, and between said cross-pieces and the pieces A are placed the short pieces a a. B represents the bearings secured by straps O on the pieces A, and D the axles journaled in them. These axles aredoweled together at their inner ends and journaled in boxes E. Thus far there is nothing on which I propose to secure protection in this application. I make the box E on the upper section with an extension, F, which is bolted through lianges .cf to the main body. This detachable extension is added to the upper section for the purpose of giving ready admission to the space used for the brasses, so that the latter may be entered or removed with facility and convenience. I also make a spout, G, on the lower section, having the incline g, and a corresponding excision, h, onthe side of brass H, so that the oil may be readily applied and flow down to saturate the porous packing under the brass. The lubricant, having saturated the packing, is gradually trasferred by capillary attraction, through brass-holes h', to the journal. This vspout is covered by a door, gf, which may be hinged to upper section or vsecured in any other suitable manner.

In order to afford proper space in the box for the reception of adequate packing, I place at the corners (and they may be placed at other points, though they are not necessary) the'vertical standards K, having shoulders 7c,

-all placed at the same height, so as to support the brass at a considerable elevation above the bottom of box.

In order to take up Wear upon the brasses,

I use two overlapping wedges, L L, having closed slot l and open end slot l', the former being a passage for the lubricant, and the latter to receive the head and neck of a bolt, M. On the latters end is a thread, by which nuts N are adjusted to draw the wedges farther down in the box, and thus keep the brasses and journals in proper alignment.

The .brass heretofore had a median recess in the upper section to receive a flange on journal; but I find that by making a similar recess in the lower section, and making that section in one piece, there is more steadiness imparted and less deflection of the axle.

Having thus described my invention, what I claim as new isl. An extension, F, clamped detachably to the upper s ection of a car-axle box, as shown and described, to enable the brasses to be easily removed and replaced.

2. The combination of spout G, having incline g, and corresponding excision on the brass, as and for the purpose set forth.

3. The combination, with an axle-box, ofthe 4corner standards K, having shoulders lc at the same altitude, as and for the purpose specilied.

4. The combination of slotted overlapping wedges L L and adjusting-screws M with the axle-box, as and for the purpose set forth.

5. A brass made in one piece, and having a median recess, 71.', in lower section, combined with both journals, as and for the purpose specified.

The above specification of my invention signed by me this 3d day of December, A. D.

JOHN M. BROSIUS.
