ARTHUR BEASLEY, OF EAST ST. LOUIS, ILLINOIS.

EQUALIZING SIDE FRAME AND JOURNAL-BOX.

Specification of Letters Patent. Patented J une 10, 1919.

Application filed September 16, 1918. Serial No. 254,307.

To all whom it may concern:

Be it known that I, ARTHUR BEAsLEY, a citizen of the United States, residing at East St. Louis, in the State of Illinois, have invented certain new and useful Improvements in Equalizing Side Frames and J ournal-Boxes, of which the following is a specificationicontaining a full, clear, and exact description, reference being had to the accompanying drawings, forming a parthereof. I r

My invention relates to improvements 1n car truck side-frames and journal-boxes, and it consists in the novel construction hereinafter described and claimed.

The object of my invention is to provlde a construction wherein the side-frames and journal-boxes may equalize the load upon the journals in an improved manner, and thus prevent undue friction and wear.

A further object is to provide an improved emergency means, which will prevent separation of the journal-box from the sideframe, as for instance in the derailment of the car, and which will not interfere in the least-with the efficient equalization function of the side-frames and journal-boxes. although readily permitting the removal and replacement of a damaged journal-box.

In the drawings,

Figure 1 is a side-elevation, partlyin section, of one end of a car-truck side frame and its journal-box.

Fig. 2 is a transverse section ofsame, the section being taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken on the line 33 of Fig. 1, looking in the direction indicated by the arrows.

Fig. 4 is a perspective view of the journalbox removed.

Fig. 5 is a detail perspective view of the locking key used in securing the journal-box to the side-frame, and

Fig. 6 is a detail perspective view of a gravity lug or dog that is used in connection with the said key.

The numeral 1 designates the ordinary car-wheel mounted upon the axle 2 having the usual journal 3. j

The numeral 4 designates the journal-box, which may be of the usual construction, although in the present illustration of my invention I have shown upon its top a transverse semi-circular bearing-recess 5 located between the parallel top ribs 6 of the box; and upon the opposite sides of said box at the ends of said semi-circular bearing-recess I have formed integral vertical locking-lugs 7, which project at arightangle from the sides of the box, and extend downwardly thereon but a slight distance below the said semi-circular recess 5, so that the pedestal jaws 8 of the side-frame 9 may have an unobstructed movement upon the sides of said box, the latter being devoid of the usual pairs of vertical guide flanges between which sald jaws are located in ordinary truck construction. I

The said side-frame 9 is provided with a cylindricaltjournal 10 formed integral therewith and extending longitudinally thereof, and located in the said semi-circular bearing 5 of the said box.

The pedestal-j aws 8 of said side frame are provided in their faces with a vertical groove 11, whereby (in assembling the parts or in removing the box) the said lockinglugs Z may'pass from the lower ends of said grooves into a segmental recess 12 located at the upper end of said grooves, and swing laterally of said frame in said segmental recess during the practical use of the truck upon a railroad track.

A'flat locking-key 14 has an integral head or flange 15 formed on its outer end, and is inserted beneath said locking-lug 7 (at one side of the box) through a key-way 16 formed laterally in the inner pedestal-jaw of said frame, and thereby prevents the accidental separation of the frame and jour nal-box. 4

To prevent the accidental withdrawal of' frame, I form an L-shaped depression 17 in the underside of said key near the inner end of the latter, and locate a gravity dog 18 in said depression at the time said key is inserted, so that when the key reaches the limit of its inward movement the said dog will rotate in said depression and the outer end of said dog will fall until it rests against the inner side of the adjacent pedestal-jaw 8, and thereby prevent the withdrawal of said key until theprojecting arm of said dog is turned upward and replaced in its former osition in the said depression.

I pre er to use but one key for each journal-box, but if .desired two could be provided, and in order that one pattern of box may answer for a truck and avoid rights and left-s I have formed lugs 7 on both sides of the box.

For a similar purpose, both jaws 8 of the side-frames are provided with the vertical grooves 11 and segmental recesses 12.

The numeral 19 designates the usual brass which rests upon said'journal 3, and 20 indicates the usual wedge.

The operation will be readily understood without further description.

I claim:

1. A car-truck side-frame having pedestaljaws, one of which is provided with a vertical groove at the upper end of which is a segmental recess and a horizontal key-way; a journal-box; a rocking bearing between said box and said side-frame, whereby the box and frame may relatively rock and equalize; a locking-lug at the side of said box located to move in said segmental recess of said frame; a horizontal locking-key in said key way beneath said locking-lug; and

means for preventing the withdrawal of said key during the operation of the truck.

2. A key for locking the journal-boxes of car-truck side-frames to said frames, consisting of a piece of metal having in one side near its inner end an L-shaped depression, and, an L-shaped dog which occupies said depression while-said key is being placed in position, but which rotates after the key is placed until one arm of said dog gravitates to a position in which it engages the frame and prevents the withdrawal of said key until said arm is replaced in said depression.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

ARTHUR BEASLEY.
