Figure 19 is a view, in end elevation, of the journal guide shown in Figures 16, 17 and 18.

Referring now particularly to Figures 1, 2 and 3 of the drawings, it will be observed that the reference character 10 designates, generally, a railway car axle which is provided with an axle journal 11 that has at its outer end an end collar 12 which extends radially beyond the bearing surface of the journal 11. The longitudinal axis of rotation of the axle 10 is indicated at 13. The longitudinal axis 13 is employed as a reference base in defining the invention in certain of the claims.

The axle journal 11 extends into a railway car journal box that is indicated, generally, at V114- and forms an integral part of a side frame of a railway car truck. The journal box 14 includes a top 15, a bottom 16 and vertical side walls 17 and 18. Side frame Walls 19 and 20 extend from the vertical side wall 17 toward the journal box at the other end of the truck or side frame as is readily understood. Positioned within the journal box 14 is a journal bearing 21 that rests upon the upper side of the axle journal 11 and is held in position by a wedge 22.

It is desirable to prevent movement of the axle journal 11 out of the journal bearing 21 which tends to take place during the starting or stopping of a train or at any time when there is a change in its speed. it is to provide for guiding the axle journal 11 within the journal box 14 and centering it substantially in the position shown under the journal bearing 21 that this invention is particularly addressed. For this purpose there is provided on each of the vertical side walls 17 and 18 a journal guide which is indicated, generally, at 25 and the details of construction of which are shown more clearly in Figures 7, 8 and 9 of the drawings. Preferably the journal guide 25 is formed of a non-ferrous metal such as a bronze casting. It has a bearing face 26 which is arranged, as shown in Figures 1 and 2, to be juxtaposed to diametrically opposite sides of the axle journal 11. When so arranged, the axle journal 11 is confined within the journal box 14 and cannot escape from the journal bearing 21. The bearing face 26 is provided with a plurality of vertical grooves 27 to facilitate the maintaining of a film of lubrication over the surface of the axle journal 11.

thereon. the heads 41 are spaced from the inner surfaces of the In order to secure the journal guide 25 in place it is in the form of an outilaring tenon or it has a wedge shape which is provided by inclined ends 28 and inclined sides 29. The rear surface 30 of each journal guide 25, as shown in Figure 2, bears against the inner surface of the respective side wall 17 or '18. The rear surface 30 in each case is provided with vertical grooves 31 for reducing the amount of material required for each journal guide 25.

The journal guides 25 are wedgingly held in operative position in a socket 34 in the form of a mortise flaring outwardly toward the respective side wall 17 or 18. The socket 34, as shown in Figures 4, and 6, is formed in a journal guide housing, indicated generally at 35, and formed preferably of a malleable iron casting. The socket 34 is provided with inclined end walls 36 and inclined side walls 37 for receiving the correspondingly inclined ends and sides of the journal guide 25.

With a view to permitting endwise application of the journal guide housing 35 assembled with a journal guide 25, the journal guide housing 35 is provided with a bifurcated section 38 as an endwise extension. The bifurcated section 38 has an endwise opening slot 39 for application to a bolt 40 which forms one of a pair of threaded bolts that are located in a horizontal plane through the longitudinal axis 13 of the axle journal 11.

As shown more clearly in Figure 2 of the drawings .the bolt 48 is provided with a head 41 which overlies the bifurcated section 38 of the journal guide housing 35 .while a nut 42 is provided at the other end. The bolt 48 extends through an opening 43 between the side frame walls 19 and 20.

The other bolt of the pair is indicated at 44 and it ex- .tends through an aperture 45 at the other end of the journal guide housing 35 and also through a registering opening 46 in the respective side wall 17 or 18. At its inner end the bolt 44 has a head 47 and a nut 48 is threaded on its other end. The heads 41 and 47 of the .bolts 40 and 44 preferably are rectangular and flanges 49 and 50 are formed integrally with the journal guide housing 35 adjacent thereto to prevent turning of the respective bolts when the nuts are tightened.

Before applying the journal guide centering means shown in Figures 1, 2 and 3 of the drawings, the openings 43 and 46 are formed in the side walls 17 and 18 of the journal box 14.

journal bearing 21 and wedge 22 have been removed.

Next the bolts 40 are inserted in the openings 43 in the side walls 17 and 18 and the nuts 42 are loosely threaded The bolts 40 are located in such position that therein is moved downwardly along the left side of the axle journal 11 with the left end or inclined end 28 ad- 'jacent the end collar 12. The spacing is such that the ,bifurated section 38 clears the bolt 40.

When the journal guide 25 has been properly located, the journal guide housing 35 is moved lengthwise with the bolt 40 interfitting in the slot 39. Next the bolt 44 is inserted and 70 finally the nuts .42 and 48 are tightened. Because of the mortise and tenon arrangement of the journal guide housing 35 and the journal guide 25, the latter is wedg- .ingly held in position against the inner surface of the respective side wall 17 or 18.

When it is desired to remove the journal guide 25 and the associated journal guide housing 35, the nut 42 on the bolt 40 is loosened while the bolt 44 is removed. Then the journal guide housing 35 can be Withdrawn endwise toward the front of the journal box 14 and, after the bifurcated section 38 clears the bolt 40, the assembly can be moved upwardly over the surface of the axle journal 11 after removal of the journal bearing 21 and wedge 22 and then withdrawn completely from the journal box 14.

Another embodiment of the invention is illustrated in Figures 10 to 19 inclusive and reference thereto now will be had. Insofar as possible the same reference characters will be employed where the same elements are used.

Figures 16, 17, 18 and 19 show a modified form of journal guide. It is indicated, generally, at 53 and preferably is of non-ferrous material such as a bronze casting. The journal guide 53 has a bearing face 54 that is arranged to be juxtaposed to the surface of the axle journal 11 at diametrically opposite positions when supported by the vertical side walls 17 and 18 of the journal box 14. Vertical grooves 55 are provided in the bearing face 54 to facilitate maintaining a film of lubrication over the surface of the axle journal 11. The journal may be.

guide 53 preferably is in the form of an outflaring tenon or of wedge shape and has inclined ends 56 and inclined sides 57. The rear surface 58 is arranged to bear against .the inner surface of the side wall 17 or 18 as the case Grooves 59 are provided in the rear surface 58 to reduce the amount of material employed.

The journal guide 53 is arranged to be positioned in a socket 60 or mortise which flares outwardly toward the respective side walls 17 or 18. The socket 60 is formed in a journal guide housing that is indicated, generally, at

61 and preferably is a malleable iron casting. The journal guide housing 61 is intended for application to the side wall 17 while a journal guide housing, shown generally at 62, of opposite hand construction is intended for application to the other side wall 18. Except for being of opposite hand construction the journal guide housings 61 and 62 are identical and thus the description of one will suflice for both.

On the under side of the journal guide housing 61 at the inner end there is provided a bifurcated section 63 which has a longitudinally extending slot 64 which is arranged to interfit with the bolt 40. Since the bifurcated section 63 is offset from the longitudinal axis of the journal guide housing 61, the apertures 43 in the vertical side walls 17 and 18 are correspondingly offset or located integrally with the journal guide housing 61 adjacent the slot 64 and aperture 65 for the purpose of preventing turning of the bolts 40 and 44 by cooperating with the square heads 41 and 47 thereof.

In'describing the application of the journal guides 53 it will be assumed that the axle journal 11 is positioned within the journal box 14 as shown in Figures 10, 11 and 12. Also, it will be assumed that the journal bearing 21 and wedge 22 have been removed. The bolts 40 are inserted in the openings 43 in the side walls 17 and '18 and'the nuts 42 are loosely threaded thereon. Next a journal guide 53 assembled in a journal guide housing 61 is inserted endwise into the journal box 14 above the end :collar 12. The left end of the journal guide 53 or' the inclined end 56 adjacent thereto is moved in close proximity therewith downwardly over the surface of the axle journal 11. This permits the bifurcated section 63 to clear the respective bolt 40. When the journal guide 53 has been located properly, it and the journal guide housing 62 are moved endwise past the bolt 40 so that it extends through the respective slot 64. Then the bolts 4 4 are inserted and all of the nuts 42 and 48 are tightened to hold the journal guide 53 securely in position.

While reliance can be placed solely on the mortise and tenon joint between the journal guide 53 and the journal guide housing 61 for holding the former in place in the latter, additional holding means can be provided by bridging portions 68 which are formed integrally with the side walls of the socket 60 and extend thereacross and interfit with the vertical grooves 55 in the bearing face 54.

Since certain further changes can be made in the foregoing construction and different embodiments of the invention can be made without departing from the spirit and scope thereof, it is intended that all matter shown in the accompanying drawings and described'hereinbefore shall be interpreted as illustrative and not in a limiting sense.
