Specification of Letters Patent.

Patented May to, real.

Application filed November 3, 1919. Serial No. 335,402.

To all whom it may concern:

Be it known that I, RAY citizen of the United States, residing at Yonkers, New York, have invented acertain new and useful Improvement in L- comotive Driving Axle Journal Boxes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates generally to locomotives and more particularly to journal boxes for the driving axles of locomotives, the principal object of my invention being to rovide a relatively simple and eflicient ournal box which, by virtue of its construction, is capable of being easily and quickly placed in or removed from proper operative position with respect to the locomotive frame.

It will be understood that the types of driving axle journal boxes now in general use are provided at both ends with lateral flanges that bear on the inner and outer faces of the pedestals on the locomotive frame. Obviously, these journal boxes when placed in position of use are entered into the journal box openings from below,

In the event that it is desired to replace one of these journal boxes, it is necessary to remove the pedestal binders from both sides of the locomotive frame, disconnect the driving rods and then drop the wheels and axles into pitsT r raise the locomotive off the wheels and axles in order to permit the removalof the journal boxes. These operations involve the expenditure of considerable time, labor and consequent expense, and it is the purpose of my invention to eliminate or minimize this expense by providing a journal box which may be readily positioned between the pedestal jaws or removed therefrom, and to provide simple and efficient means for maintaining the journal boxes in proper position between the pedestal jaws, such means preferably taking the form of brackets that are detachably secured to parts of the locomotive frame.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described,

M. BROWN, a I

and claimed, and illustrated in the accompanying drawings, in which Figure 1 is an elevational view of a part of the locomotive frame and showing a journal box of my improved construction positioned between the pedestals, said journal box being shown in section.

Fig. 2 is a horizontal section taken approximately on the line 2-2 of Fig. 1.

Fig. i 3 1s an enlarged vertical section iaken approximately on 'the line 33 of Fig. 4 is a sectional View taken approximately on the line l4 of Fig. 3.

Referring by numerals tothe accompanying drawings, 10 designates a part of the main frame of the locomotive, and formed integral therewith to the sides of the journal box opening 11 are the usual pedestals 12. Positioned in the journal box opening 11 is my improved journal box, the same comprising a substantially inverted U- shaped body o rtion 13 within the upper portion of w 'ch is arranged a bearlng member 14 of brass or analogous material, and bearing against the underside of the latter is the journal 15 of the driving axle.

Positioned in the lower portion of the box thus formed and immediately beneath the journal is a receptacle 16 that is adapted to contain waste and suitable lubricant.

Interposed between the sides of the body 13'0f the journal box and the pedestals 12 are liners or shims 17 and bridging the space, beneath the journal box opening 11 and connected in any suitable manner to the lower portions of the pedestals is the usual pedestal binder-0r tie plate 18..

Bearing on top of the member. 13 of the journal box is a suitable support 19 for the usual driving axle supported spring 20. 0

As hereinbefore stated, the types of driving axle journal boxes now .in eneral use are provided on their ends with lateral flanges which bear directly against the 1nner and outer faces 'of the pedestals, but it s noted that my imlproved journal box 1s wholly devoid of such flanges, and, therefore, same may be designated as a flangeless journal box. The main body. portlon 13 of the journal box is of such length that its end portions extend beyond the inner and outer faces of the pedestals and when ,m

proper operative position the outer face of the box bears directly against or lies immediately adjacent to theinner face of the hub of the driving wheel A. (See Fig. 2).

To maintain the journal box in proper operative position; brackets 21 of suitable design are secured in any suitable manner, preferably by means of bolts, to cross members ofthe locomotive frame, and the ends of which cross members unite with the side members of the frame at points adjacent to the pedestals 12. The outer ends of these brackets 21 extend beyond or overlie the side portions of the inner end of the body 13 of the journal box and removably secured to the overlying outer ends of said brackets are bearing plates 22 which engage directly with or,lie immediately adjacent to the inner faces of theside portions of the journal box body 13. Thus the journal boxthe pedestals after which the brackets 21 are.

secured to the cross members 10, so that the bearing members 22 carried by said brackets engage directly a aist the inner faces of'the side portions of t ebox.

A locomotive driver journal box'of my improved ',construction is comparatively simple, can be easily and cheaply manufactured, is capable of being readily placed in position for use or-removed therefrom, and therefore is instrumental in elimlnating tive frame on opposite sides of space for retainlng the journal boxes in much of the time and labor ordinarily involved in removing and replacing the generally used types of journal boxes.

It will .be readily understood that minor changes in the size, form and construction of the various parts of my improved device can be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims. I claim: f 1. The combination with alocomotive frame provided with journal box openings, of flangeless journal boxes ositioned in said openings, the outer projecting ends of which journal boxes are positioned adjacent to the hubs of the wheels carried by the axle that has bearin in said journal boxes, and

detachable brac ets disposed toward each other and secured to a part of thebllqocomoe axle position within said journal box openings. "2. The combination with a locomotive frame provided with journal box openings,

of flangeless journal boxes positioned 1n said openings, the outer'projecting ends of which journal boxes are located adjacent to the hubs of the wheels carried by the axle that has bearing in said journal boxes, detachable brackets disposed toward each other and secured to a part of the locomotive frame on op osite sidesof the axle space, and removab e bearing. plates detach-ably secured to ner faces of the journal boxes to retain them in osition.

n testimony whereof I hereunto aflix my signature October 29, 1919.
