UNITED STATES PATIENT OFFICE ALBERT 0'. Buckles, or cLnvE-LAnn, 01110, ASSIGNOB TO NATIONAL MALLEATBLE Ann STEEL CASTINGS COMPANY, or CLEVELAND, 01110, Aconronxnon or OHIO JOURNAL BOX Application filed August 12, 1927, Serial No. 212,446. Renewed July 11, 1931.

My invention relates to journal boxes, and particularly to journal boxes of the roller bearing type intended for use on freight car trucks. It is customary in journal boxes 5 usedin freight car service to attach the boxes rigidly to the car side frames and to provide for the required flexibility between the box and the axle itself by crowning the journal wedge in a direction transverse to the car and allowing a certain amount of clearance between the sides of the wedge and the box, so as to provide limited movements in both vertical and horizontal planes within the box.

When, however, roller bearings are used it is not practical to provide the necessary flexibility between axle and journal box without unduly increasing the size and weight of the box. Hence I have so constructed my journal boxes and the co-operating parts of the side frame to permit the necessary flexibility between these parts by providing radial surfaces about which the parts may move both horizontally and vertically rela-' tive to each other.

My invention also comprises various features which I'shall hereinafter describe and claim.

In the accompanying drawings, Fig. 1 is a plan of a portion of a side frame with a journal box assemjbled therein embodying my invention; Fig. 2 is a side elevation thereof; Fig. 3 is an end elevation thereof; Fig. 1 is a plan similar to Fig. 1 but with the frame and box in the position they would assume when rounding a curve in the direction indicated by the arrow; and Figs. 5, 6, 7 and 8 are transverse sections showing modified forms of top lugs.

Referring more specifically to the drawings, the side frame A is provided with depending jaws 2 and 3, the inwardly facing parts of which are of channel shape so as to provide recesses 4 therein, as is indicated in Fig. 1, to receive the side lugs 5 of the journal box B. At the top of the opening between the jaws 2 and 3 the frame has a recess 6 to receive a lug 7 formed on the top of the journal box B. Pins 8 are inserted through registerlng apertures 9 in the aws 2 and 3 below the lugs 5 to prevent separation of the box from the side frame in case of derailmentor during handling of the truck when disassembled from the car body. The pins may be held in position by the cotters 10.

To provide for the lateral movement of the frame A relative to the box B I have formed the surfaces 11 on the lugs 5, which maintained between box. and frameupon a V pair v of these surfaces, as is shown in Fig. 4c. This is of particular importance when brakes are applied, and the 'momentum of the car thrusts forwardly against the axle, carrying the side frame against the journal box with great force. V

The vertical. bearing faces 16 at the sides of the top lug 7 and the corresponding surfaces 14 are also formed on equal radii'so as to provide a full contact between a pair of such surfaces when box and frame are also angled in a horizontal plane. These surfaces 16 and 14 also serve to limit the transverse movement of the box with respect to the side frame, and hence clearance is provided at the sides 15 of the lugs 5 and ends 13 of the lug 7'to avoid contact of, such surfaces with the side frame under normal conditions.

To provide for vertical angling the top surface 17 of the lug 7 may be formed on a radius so that the box may move relative to the flat bearing surface 18 by which the box Bsupports the side frame A, as is shown in Fig. 3.

In Figs. 5, 6, 7 and 8 I have shown the top portion of the journal box formed of a separate member. InFig. 5 the separat-emember 20 seats over an upward projection 21 on the box and has an arc'shaped upper surface 22 which engages a fiat surface 23 on the side frame. In F ig. 6 the upper surface 24 of the,

separate member is flat, while the corre- :ponding surface on the frame is are aped. In Fig. 7 the separate member 26 is secured to the side frame by a projection 5 27 held in a slot 28 by a pin 29. Here the top surface 30 of the box is are shaped and cooperates with the fiat under surface 31 of the separate member. In Fig. 8 the top surface 32 of the box is flat while the bottom 33 of the separate member is arc-shaped. The purpose of employing a separate piece as shown in Figs. 5, 6, 7 and 8 is to relieve the journal box and the side frame of wear. The wear is taken on separable pieces which can be replaced or which can be made hard enough to withstand wear.

The terms and expressions which I have em loyed are used as terms of description not of limitation, and I have no intention, in the use of such terms and expreslions, of excluding any mechanical equivalent: of the features shown and described, or portions thereof, but recognize that varione structural modifications are possible *5 within the scope of the invention claimed.

- What I claim is:

1. The combination of a journal box having side and top projections thereon, with aside frame having recesses into which said at fit, means for retaining the box m'tiaeframe engaging the side projections, the top projection providing the supporting bearing for the side frame and the ends of the si e projections co-operating at times with vertically disposed walls of the recesses in the side frame. H8. The combination of a journal box and a sidmframe, the box and frame having comfilamentary are shaped surfaces to permit ateral angling between box and frame, the said box and frame having also dissimilar on gaging surfaces to permit vertical angling.

3. 'The combination of a journal box and a side frame, the box having arc-shaped surfaces substantially at right angles to each other cooperating with similarly shaped surfaceson the frame, the cooperating surfaces being spaced apart to allow limited lateral movement between the box and the frame.

4. A journal box and side frame connection in which cooperating curved surfaces are formed on the box and frame to provide angnlar flexibility therebetween, said cooperatin surfaces being spaced apart to also provi e for lateral movement therebetween.

5. The combination of a journal box and a side frame, the box having projections at the sides and top provided with arc-shaped surfaces for engagement with cooperating surfaces on the frame, a clearance being provided between the corresponding surfaces of the box and frame, the arc-shaped surfaces of the side journal box projections limiting the relative movement of the box and frame n in one direction and the arc-shaped surfaces of the top journal box projection limiting the relative movement of the box and frame in another direction.

6. The combination of a journal box and a side frame, the box having projections at the sides extending into recesses in the frame, the projections and recesses havin a substantial clearance therebetween to al ow both angular movement and bodily lateral movement between the journal box and side frame.

7 The combination of a journal box and a side frame, the box having projections at the sides and top provided with arc-shaped surfaces for engagement with cooperating surfaces on the frame, the corresponding surfaces of the box and frame having a substantial clearance therebetween, the arc-shaped surfaces at the top of the box being formed on radii substantially greater than the distance between them, thereby producing relatively flat surfaces which will allow relative movement between the box and frame in a direction to bring the arc-shaped surfaces of the side journal box projections into engagement with the side frame while maintaining an area of contact between one of said relatively fiat surfaces with the side frame.

8. The combination of a journal box and side frame, said side frame having depending jaws provided with vertically extending curved surfaces for the reception of a journal box therebetween, said journal box having on its sides curved surfaces for co-operation with said jaw surfaces to provide horizontal angular flexibility therebetween, said side frame and top of said box having co-operating surfaces one of which is curved longitudinally of said box and straight transversely thereof whereby said box is held against axial rotation but is free to angle horizontally and vertically relative to said side frame.

9. The combination of a journal box and a side frame, the box having vertical aroshaped surfaces substantially at right angles to each other cooperating with surfaces on the frame to fpermit lateral angling between the box and rame, the cooperating surfaces being spaced apart to allow limited bodily lateral movement between the box and the frame.
