v ADJUSTABLE DRIVING-BOX.

railway locomotives. and consists in im-l rovements upon the construction shown in atent No. 1,377,557, issued to Ray M. Brown, May 10, 1921. j The 'main object of m invention is'to provide means for adjusting the axle jour! nal box transversely of the locomotive pedes# tals in order to secure a proper` t when a box, pedestal, and wheel are assembled, and also to take up wear at any subsequent time.

In the accompanying drawings, which illustrate a selected embodiment of my invention,- 1

Figure 1 is a longitudinal vertical section through a locomotive pedestal, showing the journal box, axle and wheel and equipped with my invention.

Fig. 2 is a transverse vertical section on line 2-2 of Fig. 1.

Fig. 3 is a transverse horizontal section through the box on line 3,-3 of Fig. 1.

The locomotive driving wheel 1 is mounted upon the axle 2 which carries the journal box 3 in the usual-:mannen Journal box 3 is mounted in a pedestal 4 which is provided with the pedestal binder 5.

As shown in the above-mentioned Brown atent, 'ournal box 3 is flangeless, and, .so

ar as t e pedestal is concerned, is free to move transversel thereof toward and from wheel 1 or longitudinally of the axle and the journal recelvin recess in box 3.

. By reference to Fig. 2, it will be seen that the outer face of 'ornal box 3 bears against the inner face o 'the hub of wheel 1.

Pedestal 4 is provided with a bracket 6 which extends inwardly and has a pad 7 facing axle 2 but spaced therefrom a greater distance than the slde of box 3; A container "member 8 is bolted to pad 7 and is provided -with a vertical recess 9 in which a journal Specification of Letters Patent.

box shoe 10 is slidably mounted. Between shoe 10 and the rear of recess 9 is a wedge 11 which forms a bearing for shoe 10. The

contacting faces of shoe 10 and wedge 11 are inclined from the vertical and a bolt 12 passes through wedge 11 in the plane of the inclination lof the shoe Contactin4 face, engaging the top of the wedge, an its lower end passes through a rib 13 on member 8, and, by means of nuts 14, may be drawn downward to lower wedge 11 and thereby feed shoe 10 and box 3 outwardly. Member 8 is provided with anintegral ange 15 in which is screwed a set screw 16 which may beused for locking shoe 10 in any desired position. v

When the parts shown are assembled, bolt 12 is tightened until the proper fit between journal box 3, shoe 10, and wheel 2 is obtamed, and the bolt and shoe are then locked 1n position. At any time when the play between the box and the wheel becomes excessive, nuts 14 and set screw 16 may be loosened, wedge 11 inserted a suiicient distance to take up the play, and'bolts 14 and set screw16 again tightened.

If it is desired to remove box 3 for the purposes of repair, container member 81j'with shoe 10 and wedge 11 may be entirely re.

moved, 'ournal box 3 moved inwardly from the pe estal and rotated on axle 2 and dropped therefrom. As pointed out in the above-mentioned patent, this eliminatesl the necessity of disconnecting the driving rods and dropping the wheels and a'fxle into pits, or similar expensive operations( y I contemplate the usual modifications in,`

my invention, without departing Ifrom the spirit thereof, asset forth in the following claims:

I claim: Y 1. In Vcombination with` a locomotive ped` estal, .an axle journal box, and means for adjusting the movement of said box4 transl vegse 15111 of the pedestal. v

combination with a locomotive pedestal, an axle' journal box, and means adj ustable on and removable from the pedestal for limiting the movement of said box trans,-v versel of the pedestal. j

3. 151,1 combination with the pedestal and wheel of a locomotive, an axle journalvboX` movable transversely of the pedestal and f held against movement toward the wheel by engagementl of the 'hub of the wheel and against oppositev movement by an adjustable bearing shoe.

4. In a locomotive, a pedestal, a journal box therein, an integral side extension on said pedestal, a containing member removably secured to said' side extension, and journal box holding means mounted in said member and adjustable transversely of said pedestal.

'5. ln a locomotive, a Wheel, an axle therefor, a'pedestal, an axle journal box movable transversely of said pedestal, a `container member removably secured to said pedestal, a shoe slidably mounted in said member and adapted to limit transverse movement of said journal box, and a Wedgebetvveen said shoe and a surface of said member for adjusting said shoe to -coperate With said Wheel tor holding said journal box in a predetermined position.

6. ln a locomotive pedestal, a transversely extending'bracket, a container member removably secured thereto, a longitudinal re.- cess in said member, a tapered Wedge seated in said recess, a journal box bearing shoe .seated agalnst said Wedge, and means for 1n- `sertmg said Wedge between its seat and said shoe,

7. in a locomotive pedestal, a tmnsversely extending bracket, a container member removabiy secured thereto, a longitudinal recess in said member, a tapered Wedge seated in said recess, a journal box bearing shoe seated against said Wedge, a'bolt passing throughsaid Wedge in the plane of its taper, elements cooperating with said bolt and member to dravvsaid Wedge through said reiseaeoe cess, and means for ioeking said shoe in Wedge-adjusted position.

8. The combination with a locomotive trame provided with journal box openings, of Ilangeless journal boxes positioned 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 bearing in said journal boxes, and detachable brackets disposed toward each other and secured to a part of the locomotive frame on opposite sides of the axle space and provided with relatively movable means for adjustably retaining the journal boxes in position Within said journal box openings.

9. The combination with a locomotive frame provided With journal box openings, of iiangeless journal boxes positioned in said openings, the outer projecting ends of which journal boxes are located adjacent to the hubs of the Wheels carried bythe axle that has bearing in said journal boxes, detachable brackets disposed toward each other and secured to a part of the locomotive frame on opposite sides of the axle space, and removable bearing plates detachably and adjust ably secured to said brackets and coperating with the inner faces of the journal boxes to retain them in position.

l0. lin combination with a locomotive pedestal, an axle journal box, a recess therein, adapted to receive an axle journal, and means for adjusting the journal box longitudinally of the axis of the recess.
