R ILWAY JOURNAL BOX.

AppIieationllledMay 12,

This invention relates to an improvement in the Construction of journ al boxes for railway bearings and the like. There are large quantities of these boxes in use of standard a size in both outer and inner dimensions so as to fit the standard mountings for the same now in use and to receivethe standard axles. Neithertheinner nor outer size of the journal boxes can be changed becauseo't the necessity for meeting these existing standards. i v Considerable difiiculty has, however, been experienced with the present form ofjour nal box because of the narrowness of the ledges which support the journal bearing or brassesj, "permitting the brasses slipping off the ledge getting out of position with consequent damage to the various parts i i j It is an object of the present invention to overcome this difficulty by providingin the journal boxes wider supports or ledges for the journal hearings, or brasses without, however, preventing the use of suclr improved boxes with standard car axlesfland box mountings. v

A more specific object of the inventionis to provide a journal box oi the type de scribed, having instead otthe usual nai' ro-w continuous ledge, a series of wider lugs or projections which on opposite sidesof the box are staggered, the lugs onone side being opposite the space between. the lugs on the opposite side, providing 'awide support on which the journal brass may rest and permitting the standard collared car axleto be passed in a zig-zag manner between said lugs. j Another object of the invention to'proe vide a journal boxof the type described which will permit'more efficient lubrication of the bearings t Various other'objectsand advantages will appear as the description of the invention proceeds. i; In the accompanying drawings {which illustrate a preferred form of embodiment of the invention:

Figure 1 shows a sectional plan View of 50 one form of journal box with a journal member or axle partly lnserted thereln; the said axle member being outlined in dot and dash.

box partly in section on the line 2--2 of Figure 1. j v

Figl 3fshows asectional view on the line 3-3of Figure l. i

Fig. & shows a perspective view of a brass or journal bearingol the typeused in the box as shown; 1 f In the embodiment of the invention illus trated in Figure 1 of the drawings a journal box is provided withledges 11 and 12 projecting out from the sidewalls thereof in position, to support the brasses; these ledges are provided with extended portions or lugs 13-14; and 15 as illustrated and p01 tionsof lesser width as shown at 16 and 17. The arrangen'ient of these ledges or lugs is such that each wide portion iso-pposed to a narrow portion in the opposite member, and the spacing is such as to permit the collar 22 on the axle 21 to move in a zig-zag manner past each lug. f "Theaxle 2 1 with collar 22 is shown partially inserted in the box 10 of Figure 1. It will be seen that while the collar 22 might not pass the ledge members 13, 14 and 15, if the sides thereof were in straight line, it is possible with the ledges in the form shown by applying a rocking, or weaving motion w; the journal to move the collar alternately into and out of the narrow spaces between the ledges andto enable it topass the wider parts thereof. i

It will be understood that'once the collar 22Jl1as passed all the lugs 13, 14 and 15, the axle may assume true relation to the bearings with the collar-22 inside the inner lugs and the lugs extending, inwardly beyond the edge of the collar butnot into contact with the axle portion 21. f

In the assembledbearing as illustrated in Fig. Qthe edges 18 and 19 ofthe brassQO rest upon thelugs 13, 14 and. 15 and the brassin turn rests upon the'axle 21, the weight of the car resting on the top of the journal box. it it i The extra width ofthe ledges. 11 and 12 due to the projection of the lugs 13, 1 1 and 15 effectively prevent the brass 20 from slipping off' the ledges asoftenhappened with prior boxes,and the spaces 16 and 17 between the lugs, permits the lubricant which is packed in the bottom of the box to work up under the brass and then down over the journal providing better lubrication than where the edges of the brass rests on a continuous ledgeL In assembling the journal box on an axle the axle is usually the stationary member and the journal box is weaved back and forth over the collar of the axle tocause the lugs to,

pass the collar.

It will be understood that the size and shape of the lugs 13, 14, 15, etc., may be varied, that, the collar 22 need not always be wider than the distance between the lu s 13,

14 and 15 and that various other modifications and changes may be made in the embodiments of my inventionillnstrated without departing from the spirit of the invention'or the scope of the appended claims,

Which are intended to cover the provision of wider brass ledges Without interfering With the use of my journal box, with standard housings and axles. V

I Having thus described my invention, what I I claim as new and desire to secure byLet ters Patent is asv follows:

1.; In a journal box of the class described, ledges extending along the inner walls thereof, the said led'es being of irregular width and'so placed t at the wide portions on one will be oppositefto narrow portions of the other; i f r I 2. In a journal box of the class described,

1 opposite ledges Within the wallsof the said box of such form that alternating wide and narrow'portionsthereof will be. in the position that each wide portion of. one ledge is opposite to a narrow portion of the opposing ledge throughout the lengthof the said ledge members.

3. In a journal boxof the class described, internal, longitudinal side ledges having alternate recesses and. projections. therein and so placed that the projecting portions of I for use with an axle having a collar thereon,

staggered spaced projections, on the opposite inner side. walls of said box in osition to support. abrass hearing from fa ing therebetween', the space between the free edges of all the projections on each, side. being less than the diameter of the, axle. collar, and the distance. between the edge of any projection of one side for. .a distance equal to the thickness of the axlecollar tothe edge of the projection on the other side being greater than the axle collar diameter.

6. In a journal box of the class described, equipped with fittings of conventional pattern, and longitndinal shelf-like members on the inner side walls. thereof projecting inwardly beyond the journal collar, the said members being adapted to serve as retainers for a brass bearing members, and being so formed that their inner edge portions present an irregular alignment of such contour as to require the passing of the collar of a journal member with a weaving movement when same is inserted.

7 In a journal box of the class described adapted to receive a collared shaft, longitudinal ledge members located on the in ner side Walls thereof, the said ledge members having flat top surfaces adapted to support a brass bearing member, and their inner side portions formed with alternating projections and receding portions, the said projections and receding ortions so disposed that the base surfaces of the receding portions are in line with the others of the same ledge, and the surfaces of the projecting portions are in similar alignment, the distance between the projecting portions being less than the diameter of the shaft collar.

8. In a. journal box of the class described, a casing, shelfdike longitudinal projecting members within the said casing, extending inwardly beyond the axle collar, the inner. portions of the said shelf-like members presenting a broken alignment in which the narrow portions of each are opposed to, and of opposite. contour to the wide portions of the opposing member.

, 9. In a journal box of the class described an inwardly projecting ledge on each side thereof in position to support; a brass bearing from falling therebetween, and wider than the standard ledges of said boxes, and means to. permit the journal box to be assembled on an axle having a collar of greater diameter than the distance between said ledges comprising cut-away portions in staggered relation.

10. In a journal box of the class described, internally projecting means extending into the center of said box and adapted to form ledges for supporting brasscs, the effective interior extension of said means leaving a less space than that required for a collared axle and means to insert a collared axle therein.

In testimony whereof I have aflixed my signature to this specification.

LOUIS D. GREGG.
