23 Claims.

This invention relates to car trucks embodying improvements over the car trucks and side frames disclosed and covered by my U. S. Letters Patent Nos. 2,170,112 and 2,170,123, dated August 22, 1939. In said patents the side frames of a car truck are disclosed as having guiding means upon and along the side frames for guiding the brake beam at a suitable angle of inclination during the operation of the brake, such guiding means including two spaced apart guide flanges or ledges on the side frames, the upper guide flange being disclosed as formed in one piece with the side frame, so that to remove the brake beam from the truck it was moved backwardly along the guides and then removed from the guides at points above the spring seats, as the lower guide flanges or ledges extended from or merged with the spring seat, so that the beam could not be removed downwardly below. the spring seats.

It has been found desirable to remove the brake beam upwardly between the side frames, that is, upwardly from the supporting and guiding flanges below the brake beam, and to this end one object of the present invention is to form the upper flanges or ledges, which confine the brake beam, as members or pieces formed or cast independently of the side frames and to so mount them that they can be taken an from the side frames or can be mounted so as to have a movement sufiicient to allow the brake beam to be raised and removed.

Other objects of the invention are to improve to be more satisfactory to the railways using such trucks, andan object which is obtained incidental to the present improvements .is that the truck is made more or less universal in that not only may the brake beam be guided along the side frames during brake operation, but also, when the separate upper flanges ofthe guiding means are detached from the side frames, the

brake beam may be mounted so as to swing from invention and wherein car trucks and their side frames generally so as Fig. 1 is a broken side elevation of so much of a tension member and guide column of a side frame as is necessary to illustrate the present improvements;

Fig. 2 is a section on the line 2-2, Fig. 1, showing how the separate upper flange is detachably supported;

Fig. 6 is a perspective view of the wear plate for taking the friction of the ends of the beam;

Fig. 7 is a broken side elevation similar to Fig. 1, but illustrating a modification of the inveno Fig. 8 is a section on the line 8-8, Fig. 7;

Fig. 9 is a section on the line 99, Fig. '7;

Fig. 10 is a transverse section on line ill-l0, Fig. 7;

Fig. 11 is a perspective view of a modified wear plate;

Fig. '12 a section on line 12-12, Fig. '7; and

Fig. 13 is a sectional view showing the beam co flange entirely removed from the side frame, to enable the beam to be supported by hangers and to drop upon the supporting flange in case of failure thereof.

Referring to Figs. 1 to 4 inclusive they will and there is shown onlyenough of a side frame including a tension member and a guide column to indicate the position of the present improvemerits, and it will be understood that they will be duplicated at the opposite end of the side frame, that is, at both sides of the bolster window I s- 1 thereof. Also the opposite side frames of a car truck will have the corresponding improvements so that two brake beams may be guided.

The preferably hollow tension member 15 of the side frame has the bottom portion 16 below the bolster window opening and its inclined portion ll which extends in the usual way to the usual journal boxes. The bolster guide column 98 extends upwardly from the tension member and the spring seat [9 extends inwardly of the side frame for supporting the spring for the bolster. All of these parts may be of the usual 2 construction, except for the present improvements. 5

Each side frame has a preferably integral guide flange or ledge 25 upon which the end of the brake beam 2| is supported at each side of the truck. Such guide flange 25 extends to or merges with the spring seat It and extends preferably at the angle of inclination described in aforesaid patents, and said flange extends along the tension member preferably in non-parallel relation to the inclined portion l1 thereof.

An inward shoulder or abutment 22 is located at a distance above the tension member proper and to that end it extends across the lower portion of the guide column l8 and along the upper edge of an upwardly projecting side member 23 which is in the form of a reinforcing web connecting with the upper portion of the inclined portion ll of the tension member l5. Such shoulder or abutment 22 preferably extends parallel with the flange or ledge '20, and the member 23 is best integral with the column and tension memher.

The extended surface or web 25 and shoulder 22 provide at the inner side of the tension member a preformed seat having an area sufilcient to provide an inwardly facing base on which to mount a second flange or ledge 24 so that it will extend parallel with the flange 20, at a spaced distance above it. Such flange 24 provides a confining flange for the brake beam 2| when it is to be guided upon the side frame. In order to mount the flange .24 on the side frame it preferably has an upwardly extending base flange 25 fitted upon the preformed seat provided therefor by members 22 and 23. Hence the flange 24 and the base flange 25 are preferably formed from one piece of angle steel.

In order to detachably mount the beam .confining flange 24 upon the tension member, bolts 25 may be used which pass through holes in the flange 25 and the base of the guide column, together with the web 23, nuts 21 being screwed onto the threaded ends of the bolts accessible to a workman through the window opening adjacent bolster opening It. When the bolts orthe fastenings have been tightened, the edge of flange 25 will abut the inner edge of the shoulder 22 and said flange and the confining flange 24 will be rigidly secured in position. Other fastening means may be employed, if desired, in order. to rigidly mount the separately formed member 24, 25 on the side frame, and even rivets with upset ends may be employed. In the case of rivets itnls obvious that the heads thereof may be readily cut oil so that the rivets may be pushedoutcof the rivet holes, and the member 24, 25 removed.

By the provision of the beam supporting flange and the beam confining flange 24 projecting inwardly from the side frame, a guiding recess 28 is provided for receiving the end of the brake beam, so that it may be guided substantially in accordance with aforesaid. patents. It is. preferred to strengthen and reinforce the low'erend of the guide column l5 and the web 23 by means of brackets 25 cast integrally with the tension member. There is a suitable closure 35 formed at the upper end of the guide recess 28 to prevent the brake beam from falling out in that direction. Suitable cut-outs or recesses or notches ll, 32 are formed in the forward ends of the flanges 2t, 24, as these are found desirable for allowing of proper lateral approach of the wheels to the side frame, as covered by said patents.

To provide for taking wear due to the movement of the brake beam 9. suitable wear lining in the guiding recess 25 is provided, the same consisting of a plate of tempered steel or the like having a broad intermediate portion 53 to fit on the upper surface of the beam supporting flange 20, a down turned lip 34 to fit against the front edge of said flange and an upturned back member 35 to fit against the side frame, at the back of the recess 28, the upper edge of the back member 35. being tightly engaged by the beam confining flange 24 when that is mounted on the side frame. Rivets 35 are passed through the lining portion 33 and the flange 2|, their ends being upset and countersunk in the said parts.

Referring to Figs. 1 and 4, should the occasion arise that the brake beam 2i and the brake heads,

etc. thereon are to be removed from struck, it is only necessary to detach from the side frames the separately formed beam confining flanges 24, and when it is desired to again mount the beamfor guidance on the side frames its ends are supported upon the supporting and guiding flanges 20 and the confining flanges 24 again secured rigidly in position. Although the construction described is adapted for guiding the beams on the side frames, it will. be seen that when the beam confining flanges are not in position on the side frames. as shown in Fig. 13, the beam may be suspended from the usual hangers supported on the side frames, and then if the hangers should fail to support the beam, the beam will be prevented from falling to the track because it will drop onto the flanges 20 at each side of the truck.

. Hence the construction shown and described is of a dual type, that is, it may be used as a whole for guiding a beam along the side frames or in part to form a safety device to catch the beam in case it drops. In the latter case, if because of the inclination of the beam supporting flanges the beam should not come to rest thereon in the place just where it may have dropped, but would gravitate inwardly down to the spring seats, as would probably be the usual case, the seats will catch the beam and prevent it from falling to the track. Then the beam can be removed upwardly from between the side frames because the upper beam confining flanges are not in use and there are no inner surfaces integral with the side frames which would act to obstruct the raising of the beam, so that it can be removed through one of the convenient openings of 'the truck.

In the modification illustrated in Figs. 7 to 12 inclusive the parts corresponding to the same parts illustrated in the other figures have corresponding reference numerals. In this construction the vertical web extension 38 from the bolster guiding column to the tension member is somewhat differently shaped from the web 23;

and owing to the fact that it does not have the abutment shoulder 22 it does not extend so far upwardly.

The angle metal member 39 above the beam supporting flange 20 is somewhat diiferently shaped from the corresponding member of the other figures. Such member 29 isprovided with a beam confining flange 40 and a vertical base aasasso 46 frequently formed in the bottom of a hollow or U-section tension member, and then the pin is passed through the knuckles 43, 44 and the ends riveted down to form a stationary pivot for member 39.

In this modification it will be seen that the angle member 39 may be swung upwardly on the pivot 45 so that the beam may be released upwardly, and the adjacent surfaces of the vertical base flange ll. and the web 38 are in frictional contact when the angle metal member" has been swung down to the position shown. One or more' removable bolts 41 are preferably used to fasten the angle metal member 39 rigidly in using position, the bolts passing through the flange 4| and the web 38.

A wear plate of tempered steel is preferably employed in this modification, the same having an intermediate portion 48 to cover the beam supporting flange 20, a downwardly and inwardly bent front flange l9 and an upward back flange 50. Small downward teats or humps are preferably formed on the intermediate portion 48,

and when the wear plate is sprung onto the beam supporting flange 20, the said teats will take into depressions 52 in said flange, thereby mainly securing the wear plate in rigid position. To more securely hold the wear plate it is preferred that the back wall or flange 50 extend upwardly for such distance as to enter a small longitudinal recess 53 formed in the corner portion of the angle metal member 39, said member so acting after the same has been bolted or otherwise rigidly secured to the web 38 on the tension membar.

It will be obvious to those skilled in the art that various changes may be made in the disclosed constructions without departing from the invention as defined in the appended claims.
