8 Claims. ((21. 308-40) The invention relates to railway axle journal stops mounted on the side walls of a journal box at opposite sides of the journal to oppose the same and limit the movement of the journal relative to the box, jornal bearing and wedge, and to avoid pounding the edges of the bearing, waste grabbing and undue play of the journal in the box, and also to help retain either waste packing or lubricator pad in proper position and to prevent damage to the dust guard.

Among the objects of the invention are to facilitate application and removal of the journal stops to and from the box without disassembly of the trucks; to hold the stops in place securely without bolting or welding or riveting or mac ning the box; and to reduce the likelihood of the journal axis being inclined to its bearing axis.

These objects are attained by structure illustrated in the accompanying drawings, in which:

FIGURE 1 is a longitudinal section through a box with journal, bearing, wedge and stop structure in normal functional position but also showing the position of box is jacked up and the bearing, wedge and stop structure is removed.

FIGURE 2 is a horizontal section on line 22 of FIG- URE 1, some parts being broken away for better illus trati'on.

FIGURE 3 is a vertical transverse section and view on line 33 of FIGURE 2.

FIGURE 4 corresponds to FIGURE 3 another form of the invention.

The journal box has the usual Association of American Railroads contours and includes a bottom wall 1 curving forwardly and upwardly to the box opening 2, side walls but illustrates dust guard seat 8,

ing 12 is mounted on the journal and carries a wedge 14 which supports the box. The bearing sides 12a oppose the box lugs 13 which are All of the above described parts form familiar construction which functions in a well-known manner to sup- A U-shaped yoke member of spring steel has legs 22 secured to the individual stops and extending therefrom forwardly and upwardly of the box and merging with a cross piece 23 normally disposed in a horizontal plane and its axis lies in a vertical plane spaced from the stops. Elements 22 and 23 possess sufiicient resiliency to thrust the inner ends of the legs apart so that they diverge from each other as they extend from the cross piece and thereby seat stops 16 in the arcuate recesses in the box side walls between the upper faces of waste ribs 15 and the lower faces of box lugs 13.

Each stop 16 is held assembled with the yoke by a vertical pin 25 inserted through a hole in the blocks and a semiround slot in leg 22. Preferably pins 25 are split steel bushings of spring steel commonly called roll pins. They frictionally engage the sides of the holes and downward movement is limited by their contact with ribs 15.

To install the stop, the journal box is jacked up and journal wedge 14 and bearing 12 removed through the front opening in the usual manner and the stop assembly is inserted through the front opening in the box, to the position shown in broken lines in FIGURE 1, then moved downwardly and further inwardly to the position shown in full lines. Also see FIGURE 3. In both these positions, movement of the stops rearwardly of the box is limited by contact of stop fingers 16a with the forward of the box until fingers 1611 contact depending lug 24 on the box top wall for positioning wedge 14 also limits inner movement of yoke cross bar 23.

The journal bearing and wedge can be inserted between and wedge,

FIGURE 4 illustrates another form of the invention in which the box, journal, bearing and wedge are as previously described, but the stop blocks 30 are of bimetal,

to each other and to the yoke legs by rivets 34, the rivet heads being countersunk below the surfaces of the blocks.

The elements positioning the blocks and engaging the yoke may vary substantially while retaining the feature of ready application and removal of the yoke with spaced stops without modifying the box.

Other combinations details of the structure may be varied otherwise than as ments on the blocks limiting rearward movement of the blocks in the box.

2. In combination with a railway journal box having side walls and a top wall and horizontal support elements and wedge-positioning lugs on its inner side walls and a wedge-retaining lug depending from the front part of its top wall, journal stop structure comprising blocks of bearing material seated against said elements and including upstanding fingers engaging said side wall lugs, and a retaining yoke having elongated legs secured to said blocks and extending from said blocks toward the forward end of the box and engaging transverse parts of the box at the front end of the latter and holding the blocks to their seats on said elements and positioning the blocks lengthwise of the box.

3. A combination of railway journal box and stop structure according to claim 2 in which the stop structure may be moved upwardly and outwardly from the box, when the box is jacked up relative to an axle journal therein and the journal bearing and bearing wedge are removed.

4. A combination of railway journal box and axle stop structure according to claim 1 in which the yoke is of resilient material and is distorted, during application of the stop structure to the box, to exert lateral thrust on the blocks to seat them against the sides of the box, and to exertthrust on the blocks to seat them on the horizontal support elements.

5. In combination, a railway axle journal having a larger diameter collar at its outer end, a journal bearing thereon with sides projecting laterally from the journal, a filler wedge on the bearing, a journal box seated on the wedge and having side walls spaced from the journal and having waste-retaining elements extending along said walls and having a top wall with a wedge-retaining lug depending from said top wall, and having a journal box lid, and journal stop structure comprising a block seated on each of said elements beneath a projecting side of the bearing and extending substantially abreast of a substantial part of the middle portion of the journal and including an upstanding finger engaging a forwardly facing part of the box side wall, and a yoke of resilient material extending forwardly from the ends of said blocks past said journal collar and upwardly and transversely of the box between said wedge-retaining lug and journal box lid, the resilience of said yoke requiring the movement of the inner portions of said legs toward each other to enter said blocks between the box side walls and requiring the outward bowing of the yoke to enter said blocks between waste-retaining element and the projecting sides of the bearing.

6. A combination of railway journal box and stop strucdownwardly below the horizontally and at substantially the same level beyond a 4 ture according to claim 1 in which the yoke legs are of spring material and may be distorted downwardly to clear a wedge and a journal bearing supporting the same so they may be inserted into and between the loop legs while the journal stop blocks and loop are in position as described.

7. A combination of ra'lway journal box and stop structure according to claim 1 in which the forwardly facing elements are parts of journal bearing retaining stops and the stop structure blocks are beneath said bearing stops and said rearwardly facing elements comprising upstanding lugs located at the ends of the stop structure nearer the front of the box.

.8. Railway axle box stop structure comprising a U- shaped yoke having a cross piece normally'disposed in a horizontal plane, and apair of elongated legs extending transversely from the opposite ends of the cross piece horizontal plane thereof and then structure vertical plane containing the cross piece axis, the yoke being of spring material and normally positioning said legs so that they diverge from each other as they extend away from the cross piece, and being adapted to loosely straddle a railway axle journal and end collar, and a pair of blocks mounted on the end portions of said legs remote from the cross piece, the yoke being distortable to position the legs and blocks substantially parallel to each other.
