IMPROVED RAILWAY JOURNAL-BOX.

Specifieation forming part of Letters Patent No. 50,982, dated November 14, 1865; Reissue No. 2,338. dated August 14, 1866.

To all whom 'it may coment:

Be it known that I, RANsoM G. WEIGHT, of Meadville, in the county of Crawford and State oi'Pennsylvania, have invented a new and useful Improvement in Railway-Axle Journal- Boxes 5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, made partof this specification, in which- Figure 1 is a longitudinal vertical section through the center, indieated by the line cc x, Fig. 2. Fig. 2 is a plan, one-half being shown in section. Fig. 3 is avertical transverse section on the line y y, Fig. 2. Fig. 4 is a front elevation. Fig. 5 is an elevation of the inovable back detached. Fig. (i is a plan of the same.

In the different figures the same letters indicate identical parts.

I will particularly describe the changes I make iu' the ordinary railway journal-box.

The top of the box is made with a recess (indicated by the letters a and b in Fig. 1) intended for receiving the top of the hearing B, which is thus held firmly in place, lugs at the eorners ot' the hearing restin g against the sides of the recess b, preventin g lateral notion, while the ends are restra'ined by the ends of the box, so as to prcclude any cousiderable longitudinal play. The hearing is hollowed out on its under face to fit the journal A of the axle. The longitudinal play of the aXle is controlled by the projection h ou the outer end of the hearing.

The hearing may be introduced without removing the axle by the following means: The opening through the inner face of the journalbox is not made round, but elliptical, as indicated 'by the exterior lines surrounding the axle A in Fig. 3, leaving spaces l l above and below the axle, as shown in Fig. 1. By raising the box until the axle rests upon the lower edge ot' this elliptical opening, roon is given for introducing the hearing through the opening always made in the front or exterior end of the box for lubricating thejournal, &0.

The bearing thus inserted over the end of the axle is held in place by the bar m, inserted in the grooved lu gs KK, in conj unction with the ehambered recess b, already described. The box and bearing are then let down upon the axle. The space l above the axle permits the wearing of the hearing from use Without bringing the box and axle into contact. This elliptieal opening in the inner face Would permit the escape of the oil required in the box for the lubrica tion of the journal, and also the introduction ot' dust and sand into the box. To avoid this difliculty the elliptical opening must Iot be carried to the bevel of the bottom of the box, so that a suffieient chamber nay be left to retaiu the oil not Suspended bythe waste usually employed for the purpose.

On the inside or back end of the box the projeeting fianges D D', runningvertically ou both sides of the box, are forned with dovetailed grooves, for the purpose ot' receiving the dovetailed slide E F. This slide is couposed of two neatly-joined pieces, E and F. The piece E includes the half of the axle, and has U-forned projeetions extending the whole length of the slide, and having the sides e edovetailed to fit thedovetailed grooves already described. The inner faces ot' these projections have tongues fittiu g into corresponding rabbets iu the edges of the piece F, or vice Vers-a. The piece F thus slides in the piece E, and includes the other halt' of the axle, as shown in Figs. 5 and 6. The dovetailed flanges being on the outside of the box, the slides may be inserted Without removing the axle. They are held together by a rod, g, passing through then both, as shown, or by any equivalent device. These' slides, formin g a novable back for the box, fit sn ugly against the axle and in the grooves, an'd prevent the escape of the oil and the entrance ot' dust or sand.

Ido not claim to be the first to fit an adadjustable back to a railway journal-box, so as to prevent the admission of dust, &c., but

What I do claim as ny inventio, and seek to secure by Letters Patent, is

1. The dovetailed projecting fianges D 1)' and dovetailed slide E F, (the slide being composed of two pieces-constructed and united as described,) in eotnbination with the rod g, for securing the same, the parts being arranged for use substantially in the nanner and for the purpose set forth.

2. The hearing B, with its projection b and chanbered recess b, with or without the bar m, substantially as and for the purpose set forth.

In testimony whereofl have signed my name to this spcification before two subscribing witnesses.
