UNITED STATES LAWREN E R GHARDSO F C AG OI RAILWAY-CAR rRUcK.

Application fired August 21, 1'924. Serial No. 733,264.

To all whom it may concern:

Be it known that I, LAWRENCE RICHARD- soN, a citizen of the Uni-ted States, residing at Chicago, in the county of (look and State of Illinois, have invented certain new and useful Improvements in Railway-Car Trucks, of which the following is a specification.

This invention relates to railway car trucks, and more particularly tocooperati-ve features of side frame and journal box con- .struction.

One objectof the invention is to provide a simple and durable side frame which requires a minimum amount of metal consistent with good design.

Another object is to provide a simple and durable side frame and journal box construction wherein the parts cooperate in a manner to meet all of the requirements under service conditions.

These and other objects are accomplished by means of the arrangement disclosed by the single figure of the drawing, which is a fragmentary side elevation of a railway car truck embodying my invention.

The various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring to the single figure of the drawings, it will be noted that the invention is illustrated in connection with a railway car truck including an integral side frame having a compression member 10 and tension member 11 which are joined to each other at points just inwardly of the journal boxes 12. The side frame has the usual bolster columns 13 forming an opening for a bolster 14 which rests upon springs 15.

Heretofore journal boxes have been received between jaws, the outer ones of which are rather extensive and, as a result thereof, are heavy. While I make use of a single journal boxjaw which is the inner one 16, by means of my invention the outwardly and relatively heavy journal box jaw is eliminated and the same function performed by a simpler and lighter construction. Since the amount of metal used in producing the inside jaw 16 is inconsiderable, no change need be made in connection therewith.

As is appreciated, the main purpose of the journal box jaws is to restrain the journal box against bufling and jerking actions. The problem is to overcome such forces. By

using the inner journal box jaw 16 that side of the construction is provided for. Instead of using the large heavy jaw which ordinarily embraces the outer side of the journal box, I have provided a relatively small hook 17 which forms an integral end of the side frame, said hook having a downwardly ex tending portion 18 and an inwardly extending tongue portion '19 which fits into a horizontally arranged groove 20 in aside wall of the journal box '12. As shown at the left hand side of the figure, the left hand groove 20 in the journal box 12 receives the tongue 19, whereas, at the right hand side of the drawing, the right hand horizontal groove 20 receives the tongue 19. Accordingly, in order to avoid the use of right and left hand journal boxes and to make said journal boxes interchangeable, both sides of each journal box are provided with grooves. In order to secure the journal box 12 in its operative position against all forces and coopcrating with the jaw 16 and the hook 17, a bolt or other suitable fastening member 21 is passed through an apertured car 22 of the journal box and through the web portion of the jaw 16. Here again the journal box is provided with apertured ears on both sides to avoid the manufacture of right and left hand boxes.

Considering the left hand end of the truck as shown in the figure, it will be appreciated that a force applied in one direction will be taken by the face of the jaw 16 and a force in the other direction will be taken by the hook portion 18. It is appreciated that when the hook 18 takes the blow that there will be a tendency for the journal box to rotate about said hook. However, such rotation is counteracted by locking the journal box, as at 21, to the Web of the jaw member 16. Of course, rotation of the journal box in any other direction is prevented by cooperation of the parts. By means of this arrangement a simple and durable side frame and journal box arrangement is provided, which is adapted to meet the various requirements under service conditions and at the same time reduces the weight and cost of the side frame.

I claim- 1. In a railway car truck, the combination of a side frame having a journal box jaw and terminating in a hook portion adapted to cooperate with said jaw for the reception and retention of a journal box against rotative movement, and a journal boxmounted between said jaw and hook portion.

2. In a railway car truck, the combination of a side frame having a journal box jaw and terminating in a hook portion adapted to cooperate with said jaw for the reception and retention of a journal box, and a journal box having a horizontally arranged groove for receiving the hook portion.

3. In a railway car truck the combination of a side frame having a journal box jaw and terminating in a liookportion adapted to cooperate with said jaw for the reception and retention of a journal box, a journal box having a horizontally arranged groove for receiving the hook, and means for looking said journal box to said jaw.

4. In a railway car truck, the combination of a journal box having a horizontal groove in a side wall thereof, and a side frame having a journal box jaw' and terminating in a hook portion to pass into said groove in 00- operating with said jaw, said jaw taking the reaction in one direction and said hook taking the reaction in another direction, and means associated with said jaw for assisting said hook in retaining the journal box in its operative position.

5. In a railway car truck, the combination of a journal box having a horizontal groove in a side wall thereof, and a side frame having a journal box jaw and terminating in a hook portion to pass into said groove in cooperating with said jaw to retain said journal box in position, and means for locking said journal box to said jaw.

6. A side frame for a railway car truck including tension and compression members and a journal box jaw, said side frame terminating in a hook portion for cooperating with the journal box jaw to retain a journal box in position against any rotation.

Signed at Chicago, Illinois, this 18th day of August, 1924.
