JOURNAL-BOX.

Specification of Letters Patent.

Patented J an. 2, 1917.

Application filed June 10, 1912. Serial No. 702,681.

T all whom it may concern:

Be it known that I, FRANK D. SHELDON, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of IVisconsin, have invented certain new and useful Improvements in Journal- Boxes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to journal boxes for use in connection with railway cars and locomotives and has for its object the provision of means carried by or integral with the journal box casing to prevent the bearing wedges and brasses from being displaced should the car or locomotive leave the track. In the past it has been necessary to inspect the journal boxes whenever a car or locomotive jumped the traclr in order to see that the bearing brasses and wedges were in proper position on the journal. If in inspecting the journal boxes it was found that the bearing brasses or wedges had been displaced, it was necessary to lift the car or locomotive to release the strain on the j ournal so that the bearing parts might be readjusted. My invention obviates this difficulty by providing means for retaining the bearings and wedges in proper position upon the journal at all times whether or not the weight of the car or locomotive is bearing upon the journal.

In one application of my invention the means provided for retaining the journal, bearing brasses and wedges in proper position is so conformed and placed that it acts as a dust guard to prevent dust and dirt from going into the journal box.

My invention is illustrated in the accom panying drawings forming a part of this specification, in which Figure l is a front View of the journal box of my invention showing in part the h means for securing the same to the car or locomotive with which it is associated; Fig. 2 is a side sectional View of the journal box and the car wheel upon whose journal it is disposed, taken on the line 22 of Fig. 1; and Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Similar numerals refer to similar parts throughout the several views.

In Figs. 2 and 3 of the drawings, the car wheel is shown at 1, the journal at 2, and the journal box casing at 3. At 4 is shown the spring through which the weight of the car or locomotive is transmitted to the journal box. One end of this spring rests the frame of the car or locomotive as showw in Fig. l of the drawings, the other end being disposed upon a stud 5 carried by the journal box casing 3. A suitable pedestal 6 is provided to retain the journal box in position relatively to the framework of the car or locomotive. The journal box may be secured by means of the bolt 7 and the'nut 8 carried by the pedestal 6.

The strain exerted upon the journal box casing 3 through spring 4 is transmitted to the journal 2 through the wedge part 9 bearing against the underside of the top of the journal box casing 3 and brass bearing 10. The bearing 10 is preferably provided with a Babbitt lining 11 as shown in Figs. 2 and 3. The casing 3 is provided with inwardly projecting portions 3 which serve to prevent lateral displacement of the wedge 9.

In order to retain the wedge 9, brass bearing 10 and the journal box 2 in proper position relatively to each other at all times, I provide a retaining plate 12. This plate is preferably semi-circular in shape to fit the journal 2 and is retained against the lower side of the journal opposite the seat of the brass 10 by means of the adjusting screw 13 carried by the journal box casing 3. The retaining plate 12 serves to hold the journal 2 in proper position relatively to the journal box at all times. The wedge 9 and the bearing 10 are therefore prevented from being displaced, thereby avoiding the difliculties experienced with journal box arrangements of the prior art when the car or locomotive left the track. When a car is derailed and the journal drops down there is a tendency for the outward end of the journal box to tilt upward. For this reason, although I prefer to place the retaining plate toward the rear of the journal box to exclude dirt and sand, I place the retaining plate under the journal opposite the seat of the brass. In light weight cars, such as are employed in coal mines and the like, or construction work, which frequently leave the track, due to rough track, or stones or other obstacles on the rails, it may be desirable to place the retaining plate well toward the front of the journal box thus securely holding the journal and brass in proper polltl sition and efiectively doing away with all lost motion; As best illustrated in Fig. 2, the plate 12 serves to prevent dust orgrit from entering the oil cellar 1 1. The door or lid 16 is normally held in closed position by the spring 17 which is so apparent from the drawing that no further reference need be made to this feature. 7

While I have shown my invention in the particular embodiments shown in the'drawings, I do not wish to be limited to these constructions, as it is apparent that other equivalent constructions may be employed without departing from the spirit of my invention.

What I claim and desire to secure by Letters Patent is:

In combination an axle for a car wheel, a journal box inclosing a portion of said axle, said axle having a wearing surface forming a finished bearing, a removable journal member lying inside the top of the box and engaging the finished bearing surface of the axle, said removable journal being held in place by the downward pressure of the box, a wedge member between the top of the box and the journal member, a retaining plate presented edgewise to the axle below the bearing surface but normally out of contact with the same, and means to support said retaining plate to prevent the journal member from being displaced, said journal box having an oil cellar in the lower portion thereof below said axle, said retaining plate lying adjacent one edge of said oil cellar and closingofl' the same to form a dust excluding means.

In witness whereof, I hereunto subscribe my name this 7th day of May, A. D. 1912.

FRANK D. SHELDON.
