Specification of Letters Patent.

Patented June 6, 1916..

Application led June 16, 1915, Serial No. 34,374. Renewed April 14, 1916. Serial No. 91,261.

T o @ZZ whom it may concern Be it known that I, MonniLL DUNN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Journal-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same. 4

My invention has for its object to provide an improved journal box cellar, and to such ends generally stated, the invention consists of the novel construction and arrangement of parts hereinafter described and defined' in the claims.

The cellar illustrated in the drawings is a pressed steel or sheet metal structure especially designed for incorporation in a journal box ofthe type disclosed and claimed in U. S. Letters Patent No. 1,077,159, issued to Ivar A.. Randel, of date, October 28, 1913, but thev invention is capable of more general use, and insome instances, may be cast integral with the top of the box.

In the drawings, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a side elevation; Fig. 2 is an outer end elevation; Fig. 3 is an inner end elevation; Fig. 4 is a bottom plan view; Fig. 5 isa plan view; Fig. 6 is a section taken on the line m m6 on Fig. S; Fig. 7 is a section taken on the line x7 m7 on Fig. 5; and Fig. S is a. section taken on the line S m8 on Fig. 5, all showing the improved cellar as formed from she-et steel and particularly designed for the above noted special purpose.

In forming the cellar from sheet steel or other sheet metal, it will be pressed into the v form shown by means of suitable dies, and the entire shell l of the cellar will be formed integral from a single sheet. The bottom of the cellar is rounded or made approximately semi-cylindrical, as indicated at 2, except at its central portion, where it is formed with rectangular depressions 3, the outer faces of which are flush with the parallel sides of the cellar and the horizontal bottom surface of which is in a horizontal plane that is tan-v form vertical channels 4 that afford clearance for the journal box bolts. At its inner end1 the cellar has an inwardly bent flange 5 that forms the outer dust guard wall. The parallel sides of the cellar, at the front end thereof, are formed with inclined edges 6 to afford a lid seat, and the bottom of the box, at its outer portions is curved upwardly at 7 to a'point high above the bottom of the box and to a point where it joins with the lid seat 6. Approximately at the point where the curved portion 7 joins the central or lowest part of the cylindrical bottom ofl tion of a. hoisting jack to lift the box and its load, without crushing the cellar, and are.

disclosed and claimed in the joint application, filed of even date with this renewal and amendment by Messrs. Alvin C. Mc- Cord and Ivar A. Randel.

The journal box cellar constructed as above described, may be made comparatively light, and at the same time,.will have very great strength. By rounding the bottom of the boxsaid bottom is brought up as close as practicable to the journal and the amount of oil and waste necessarily contained in the vbox is reduced to a minimum and kept in better engagement with the journal. The depressions 3 afford a flat bottom or seat for engagement with the tie bar of the truck frame, and not only stiften the box, but distribute the load strains properly throughout the cellar. On account of the sides of the cellar being brought down vertically, making. a right angle connection with the flat tie bar, the journal box bolts which secure the box to the arch frame, passing through the arch bar and tie bar of the frame, are given a bearing throughout, their entire length which would not be the case unless this flat depression was made in the bottom of the box. This is important because, while theoretically, the strains onthe journal box are all in the upper part of the box where the bearings and brass come into engagement with the inside lugs at the top of the cellar, actually, on account of the imperfections in arch bar frame construction, there is also considerable strain thrown upon the bottom part of the bolts by the tie rod, which would tend to bend them out of line, or twist the box out of line, unless the bolts have some engagement or Contact with the box at its lower edge. The strains so put upon the journal box bolts, due to imperfections in the construction of the arch bar side frame, will be taken as a shearing strain on the bolts, whereas, if the box be without the angular depressions 3, such strains would be thrown on the central portions ofthe bolts, causing the same to be bent, and thereby rendering the tie bar useless. Adjacent to the said flange 5, the vertical walls of the cellar are preferably pressed slightly outward at 11 to afford shallow vertical channels that are adapted to receive the inner dust guard wall and to afford a dust guard seat. The perforations 12 shown in the upper portions of the side walls of the cellar are provided to facilitate the casting fast thereto, of a cast metal top, as disclosed and claimed in the prior patent above identified.

The cellar described has features of construction which are especially desirable in a pressed steel or sheet metal cellar, but which, nevertheless, are highly desirable in a cast cellar, such as a malleable iron cellar, where a thin shell of approximately uniform thickness is required. Both` in pressed steel and in malleable journal box cellars, the shell should be of uniform thickness. The angular depressions 3 provide this feature in a cellar having a rounded bottom, and they cooperaterwith the rounded bottom portions which are both inward and outward thereof, to very greatly stiffen and truss the cellar a its lower side portions. l Y

What I claim is:

1. A journal box cellar having a rounded bottom and provided with angular depressions at the opposite sides of its intermediate rounded portion, and which depressions afford a fiat bearing for the tie bar.

2. A journal box cellar having a rounded bottom and provided with angular depressions at the opposite sides oflits intermediate rounded portion, and which depressions afford a fiat bearing for the tie bar, the outer faces of said angular depressions being in the plane of the sides of said cellar, and the lower surfaces of said angular depressions being in a plane that is approximately tangential to the said rounded bottom.

3. A journal box cellar having a rounded bottom and provided with angular depressions at the opposite sides of its intermediate rounded portion, and which depressions afford a flat bearing for the tie bar, the outer faces of said angular depressions being in the plane of the sides of said cellar and the lower surfaces of said angular depressions being in a plane that is approximately tangential to the said rounded bottom, and the sides of said cellar and the vertical walls of said angular depressions having an inwardly pressed corrugation affording clearance for journal boxl bolts. f

l. A journal box cellar having a rounded bottom and provided with angular depressions at the opposite sides of its intermediate rounded portion, and which depressions afford 'a flat bearing for the tie bar, the said cellar at the inner extremity of its rounded bottom and side walls, having an inturned flange affording an outer dust gua-rd wall.

5. A journal box cellar having a rounded bottom and provided with angular depressions at the opposite sides of its intermediate rounded portion, and which depressions afford a flat bearing for the tie bar, the shell of said cellar having approximately the same thickness throughout.

6. A pressed steel cellar having a rounded bottom and formed with angular depressions at the opposite sides of its intermediate rounded portion, and which depressions afford a flat bearing for the tie bar.

In testimony whereof I affix my signature in presence of two witnesses.
