JOURNAL-BOX FOR GARS.

TO ALL WHOM 1T MAY OONCERN:

A Be it known that I, G. H. CLEMENS, of Baltimore, in the county of Baltimore, and State of Maryland, have invented certain new and useful Improvements in Journal-Boxes for Railroad Gars.; and I do hereby declane that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw-v ings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it. Myinvention consists in constructing a journal-box in such a manner that the portion which rests upon the journal shall be capable of adjusting itself to the journal at all times, and shall also furnish a reservoir forV containing the lubricating oil. It further consists in inserting into suitable openings in the bearing surface of the box, pieces of wood in such a manner as to permit the oil to pass through their pores to the journal, as hereinafter explained.

Figure 1 is a. side elevation of a car-truck with my improvements applied, having a portion shown in section to represent the internal construction of the journal-box. I l

Figure 2 is a vertical section taken on the line z a: of fig. 1.

Figures 3, 4, and 5 are views of portions detached.

I construct the shell or outer portion of my box of two hemispherical castings,IG and H, joined on a horil zout-al central line, as shown in iig. 1, and having an opening on their inner side suiiicient to receive and enclose the journal F, as shown in iig. 2. I then construct the box E of a suitable size to fill the space above the journal within the upper portion Gr of the case, this 'box E being made spherical on its outer surface to fit the inner.

surface of the case G, and being concave on its lower surface to lit the journal F, as shown in figs. 1, 2, 3, and 4Q The box E, I make hollow, to form a reservoir to contain the oil for lubricating th'e journal, and in its concave` face, where it rests upon the journal, I fornigseveral oblong openings, which Illl with blocks of wood, as repre-y sented by a, iig. 4. These blocks are driven in endwise, and have their upper ends resting against the upper wall of the box, while their lower ends fill the openings,` and come .flush with" thc-concave or bearing surface, as

represented in iigs. 1 and 2. Small holes e are bored through these blocks transversely, to permit the oil to iiowV freely to all parts of the reservoir, and also to penetrate the wood readily, the intention 'bei-ng to have the oil-"- pass gradually through the pores of the wood to the journal, and thus to keep the journal constantly lubricated,vv the ends ofthe blocks at the same time forming a very durable bearing, much less` likely to heat than metalA bearings. A hole, u, is formed in the upper wall of the box E, as represented in fig. 3, this hole coming in a position to receive the oil poured through a hole, z', in the upper part G of the case, as shown in fig. 2, there being a similar but larger opening, t, in the lower portion H ofthe case, to permit the removal of the sediment that accumulates within the case about the journal. These openings z and t are closed by Stoppers a, which-arez composed ofl leather or other elastic material secured to a metal handle, as represented in iig. 5. Upon the upper surface of the box E is a projection, 7L, which fits into a corresponding recess in the upper part G of the case, as shown in tig. 1,*the recess being larger than the projectioulnso as to permit the box Eto move in all directions to a limited extent, in order to adjust itself to the position of the journal, the projection serving to y prevent the box E from turning so far as to get out of place on the journal. The box E enclosed within the case, is placed upon the journal as described, and the whole is then held in place by means of a strong iron stirrup or loop, D, which surrounds the case vertically, fitting in a groove, m, formed thereon, as shown in iig. 2, the upper ends of the loop being bolted rmly to the car-frame A, as shown in iig. 1. A strong iron bar, B, having its ends curved to iit over the cases, and resting in the groove on their upper portions, is arranged, 'as shown in iig. 1, and supports the framel of the truck by a rubber spring, C, or by a series of springs suitably l located, the curved ends of thebar B passing through slots cl formed in the loops I), which permits a vertical,

but prevents any lateral, movement of the bar, and the cases and boxes. In order to keep the caseclosed, when the spring yields so as to permit them to rise in theloops, a spring, n, is placed ina recess between the bottom of the case H and the loop D, as shown in fig. 1, this spring being stiif enough to raise the part H, and keep it pressed up close against the part G, when -the latter is raised by any means. If preferred, the bar B may be dispensed with, and the spring C may be placed directly over the boxes, between them and the frame A, or any other suitable arrangement may be adopted, aspreferred, It will be seen that the box E, being perfectly spherical on its upper surface, and the inner surface of the case Gr being made correspondingly spherical; the box will turn in any direction sufficiently far to readily adjust itself to the positionof thejournal, and thus inuclx wear and friction, and also heating of the journals and boxes, will be avoided. The lubricant penetrating tue wood blocks will constantly and gradually work through the pores ofthe wood, and thus keep the journal constantly lubricated, and, if necessary, very small holes-made lengthwise of the blocks to a more free flow of the oil or other material used for lubrication.

Having thus described my invention, what I claim, is-

1. The hollow box E, having the blocks of wood arranged therein, said bo'x being formed spherical on its upper surface, to permit of its adjusting itself to the journal, as herein described.

2. In combination with the box E, constructedas described, I claim the case, composed of the parts G and H, constructed as set forth.

G. H. CLEMENS.
