To all whom it may concern:

Be it known that I, HERBEKI' H. WIL- LIAMS, a citizen of the United States, and resident of Brooklyn, New York, have invented certain new and useful Improvements in Journal Boxes, of which the following is a specification.

My invention aims to provide certain 1mprovements in journal boxes and provides a practical method of manufacturmg such boxes or the principal parts thereof of stamped or forged steel; thus permitting a considerable reduction in the weight, a more accurate and a stronger product, and effecta reduction in the cost of manufacture. 1y invention also makes it possible form the various paits with absolute uniformity and to combine them solidly and accurately intoa journal box which is not only lighter but is also of greater strength and more uniform dimensions than have been possible by previous methods.

The accompanying drawings illustrate an embodiment of the invention.

Figs. 1, 2, 3, a, 5 and 6 are perspective views illustrating respectively the complete box, an inside stop piece, a dust guard casing, an arch bar seat and upper and lower segments of which the cellar is formed;

Figs. 7 and 8 are respectively longitudinal and transverse vertical sections on the correspondingly numbered lines in Figs. 8 and 7 Figs. 9, 10, 11 and 12 are views similar to Figs. 7 and 8 illustrating modified details.

The principal feature of the invention is the making of the cellar of two segments, illustrated for example, in Figs. 5 and 6, of sheet metal drawn, pressed or stamped into shape and afterwards united along their edges to form the complete cellar ready for the addition of the other parts. The journal box shown is of the Master Car Builders type and is divided along a horizontal longi-j 12 forming parts of the sides thereof which are bent in to form the usual outer grooves 13 for the fastening bolts of the car bolster. The sides 12 at their inner ends are bent outward to form portions 14 of the edges of the dust guard pocket, extending beyond the inner edge of the top 11 and united by a plate 15 which forms part of the inner wall of said pocket. The line of division between the two segments, indicated by dotted lines in Figs. 7 and 8, is located above the lower edge of the outside openin on which rests the usual lid or cover. he outer end of the upper segment, Fig. 5,.is, therefore, open.

The lower segment, Fig. 6, includes the bottom plate 16 of the cellar and side portions 17 with grooves 18and

portions

19 and 20 of the edges and inner wall of the dust guard pocket, these parts restering with the

parts

12, 13, 14: and 15 of 1 ig. 5. These two segments are brought together along their horizontal edges and united by welding. For this purpose we may use, for example, the electric welding method described 1n the patent of Thomas E. Murray, jr., No. 1,281,636 of October 15, 1918.

The box may be divided along various other lines than those illustrated. For example, it might be divided along a vertical longitudinal plane into two symmetrical halves afterwards welded together. Or it might be divided into more than two segments, to be united along various lines. And the" segments might be shaped to include only the cellar proper, without the dust guard pocket, or to include in addition several of the other elements hereinafter referred to and generally shown as separate parts welded in place.

Assuming the segments of Figs 5 and 6 united as described we have the finished cellar of Fig. 1 with its top Wall 11, bottom wall 16 and side walls21, and with the ends 22 and-rear wall 23, Fig. 7, of the dust guard pocket complete.

The arch bar seat 23, Figs. 1 and 4, is made of a single rolled steel plate welded on thetop of the cellar and with bolt openings aligned with the grooves 24 in the sides of the latter.

The tie bar seat 25 is also made of a separate piece of rolled steel bent up to form flanges 26 embracing the sides of the cellar and is welded to the bottom of the latter and has the necessary bolt openings in line with the grooves 24. The design of the arch bar seat and also of the tie bar seat will depend upon the kind of car and bolster with which the journal box is to be used. The exact dimensions of these parts and articularly the distances between their hearing faces and from such bearing faces to the inside sto pieces of the journal box are of consideralile importance, and greater accuracy can be. secured. by making them or rolled or sheet steel than by making them or either of them of cast steel oriron.

'metal. Preferably I shape this as in Fig. 2

of a plate27 welded on the underside of the top of the cellarand provided with downward side flanges 28 and 28' const tutmg the guides or side stops for .the bearing blocks and with a short forward flange or flanges 29 constituting front stops therefor. Pref -erab1y also at the rear edge of the plate 27 I bend up a' flange 29 constituting part of an outer wall. of the dust guard pocket opposite the inside wall 23 thereof. See Fig. 7.

Instead of bending up the flange 29 to form part of the pocket from the end of the inside plate 27, as in Fig. 7, the top 11 of the cellar :may be bent up as in Fig. 10 to form a flange 30 serving the same purpose, the plate 27 having its end flush with the face of the flange 30.

The top of the box is usually provided with a door hinge lug cast -integrally. I prefer to make such a lug in 'a separate piece as indicated at 31, Figs. 1 and7, and to weld the edges thereof on the top'll of the cellar.

However, this lug may be formed as in Fig. 9, by extending the top 11 of the cellarv outward and bending it up in aflange 32 and back on itself in a second flange 33, the edge of Which may-be welded to the plate.

Or this lug may be formed as in Fig. 11 by extending the central part of the plate 27, the part between the lugs 29, forwardand bending it upward. in a flange 34 and back on itself in a second flange 35, the edge of which is welded to the top plate 11.

The dust guard pocket with its end walls 22 and its outer and

inner walls

29 and 23,

carries a separate dust guard casing 36, Figs. 3 and 7, with an outward flange 37 around its upper edge. As illustrated-it is made of a single piece of sheet metal stamped with the required flanges and with

openings

38 and 39 and then bent up along the edges of.

the bottom 40 as shown in Fig; 7. It' fits in the dust guard pocket, with its flange 37 extending over the topof the latter. .When' in place it is held with. its edges together and there is no necessity of'welding such edges, though they may be welded for convenience in handling.

In some types of journal box the bottom of the dust guard-pocket and easing are open to permit dust to. fall through, and

such a'design may be adopted in journal boxes made according tot-his invention.

more firmly against the strains to which it is subjected in the direction of the car axle,

the walls of the cellar may be shaped to fit in the space between thefianges 28 and thus to lock the stop piece against inward or outward movement. Fig. 12 shows such a scheme. The upper part of each sidewall 'of the box is bent inward'to form a projection 41 to fill the space between the flanges 28 of the stoppiece. side of the box a depression in line with but somewhatdeeper and wider than the grooves 21 which carry the fastening bolts. The stop piece'contains all the stops usual in this style. of journal box, front and back stops for the wedge and side and the journal bearing.

By the use of this stop 'piece it is possible to secure absolutely accurate and uniform dimensions at the points required without the necesity of anyother machining. The forming of the dust guard casing of stamped steel. secures a uniform and smooth recep-' tacle for the insertion of the dust guard. It is advantageous also to form the arch bar and the tie bar seats separately of stamped or forged steel. They can thus be made accurately and uniformly and can be conveniently fastened to the cellar.

The various parts .may be fastened together in numerous ways. The preferred method is by electric welding. Other means may be employed however, such as riveting or a combination of riveting and welding, to accomplish the same result; and welding by other than electrical methods may also be use The particular order in which the parts are assembled in the manufacture of the journal box is chieflya matter of convenience and may be varied according to the method of fastening the parts together. In welding them as described, for example, the

i stop piece and hinge lug and the pocket casing. are preferably assembled with the upper segment of the cellar before this is united to the lower segment; and after such union the arch bar seat 23 is welded on the upper This forms on each guides for the wedge segment and the tie bar seat 25 on the lower segment. A fin of metal will generally be extruded along the inner and outer faces of the welded joints, and this will be removed, at least in so far as:it interferes withthe application of the

seats

23 and 25 and with the use of the journal box.

The dividing of the cellar along the horizontal plane calls for a comparatively short line of weld, which makes the drawing of the segments comparativelyeasy'and which also makes iteasy to get atand to remove the fins formed in the welding operation. It also locates these fins where they will not interfere with the mounting of the inside'stop piece and the top and bottom seats. In order to hold the inside stop piece that illustrated and it is understood that the ularity in detail certain embodiments of my.

invention, yet it is not to be understood therefrom that the invention is restricted to the particular embodiment disclosed. Vanous modifications thereof in detail and in the arrangement of the parts may be made by those skilled in the art without departing from the invention as defined in the followin claims.

at I claim is:

1. A journal box the cellar of which consists of a plurality of sheet metal segments meeting each other edge to edge and united by butt-welding along the entire line of their meeting edges and leaving their faces smooth.

2. A journal box the cellar of which consists of two sheet metal segments meeting each other along horizontal longitudinal edges at the sides of the cellar and united by butt-welding along the entire line of their meeting edges and leaving their faces smooth.

3. A journal box the cellar of which consists of sheet metal segments welded together and forming the top, bottom and sides, in combination with an arch bar seat, a tie bar seat and an inside stop piece, each separately formed and fastened to the cellar.

4. A journal box having a top, a bottom and sides of sheet metal and having a separate arch bar seat thereon.

5. A journal box having a separate inside stop piece on the underside of the top of the cellar said inside stop piece having a flange forming part of the dust guard pocket.

6. A journal box having a cellar of two sheet metal segments welded together and a dust guard pocket having two parts, one of which is integral with each of the respective se ments of the cellar.

A journal box having a cellar and a dust ard pocket and having a separate dust guar casing in said pocket.

In witness whereof I have hereunto signed my name.
