SPRING-EQUALIZED TRUCK.

Specification of Letters Patent.

Patented Aug. 4, 1914.

To all whom it may concern:

Be it known that we, F RANKLIN L. BARBER and EDWIN IV. Venn, citizens .of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Equalized Trucks; and we do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to car trucks, and has for its especial object the provision of a spring equalized caboose truck.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in p the claims.

In the accompanying drawing which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a side elevatlon showing the truck with the wheels and journal box removed; Fig. 2 is a plan view of the parts shown in Fig. 1, some parts being broken away; Fig. 3 is a vertical section taken on the line as w on Fig. 1, some parts being broken away; Fig. 4 is a horizontal section taken on the line 20* w on Fig. 1, and Fig. 5 is a fragmentary view showing portions of the truck in side elevation.

It may be here stated that the salient novel feature of the improved truck herein disclosed and claimed is the arrangement whereby an equalized truck with double acting springs is obtained without the use of equalizing bars or pedestal journal boxes.

The side frames 1 of the truck are preferably of cast steel with frame extensions 2 which rest on the journal boxes and support the frame and its load from the journal boxes. The journal boxes are not shown, but would be located between the frame extensions 2, and a T strap 3, that are-formed from fiat bars reduced at their inner ends and passed through holes in depending portions of the frame and secured thereto by nuts 4.

As shown, the cast side frames 1 are formed with openings 1, 1", a'nd 1. The openings 1 are simply to give lightness to the frame, but the openings 1 and 1 perform other and more important functions.

Theopenings 1 have extended brackets or spring seats cast integral with the truck side frames to receive and hold the base of coi led springs 5 that are surmounted by saddle caps 6 to which they are pivotally connected. On the outer and inner sides of the truck side frames 1, are solid link hangers 7, the upper ends of which are pivotally connected 111 pairs to the upper ends of the saddle caps 6, by means' of pins 8.. The lower ends of the pairs of links 7 carry jib pins 10 on which rest the ends of elliptical equalizing springs 11.

The laterally spaced side frames 1 are rigidly connected by cross transoms 12 located in the lower corners of the openings 1 and riveted to adjacent flanges of the said side frames. The flanged upper portions of the sides of the frame openings 1 afford columns 1', between which the ends of the truck bolster 13 are arranged to work with freedom for limited endwise movements of said bolster transversely of the truck. The bolster does not directly engage with the faces of the columns 1 but directly engages with channel-shaped guide pieces 14, which, in turn, work vertically on the faces of the said columns, but by their channel-shaped form are held against movements with the bolster transversely of the truck. movements of the bolster are limited, as shown, by stop flanges 15 on the ends thereof, and which engage with the guide pieces 14. The said guide pieces 14 have lips 16.

that rest upon, and vertical ribs 17 that interlock with the end portions of a combined spring cap and roller base 18, which latter has a flanged piece seated upon the hub 11 of thecooperatingequalizing spring 11.

Lateral motion bearing rollers 19 are interposed between the ends of the bolster 13 and the underlying spring cap and roller bases 18, and the-said members 13 and 18 are provided with the customary, or any suitable form of concave seats, whereby the bolster is yieldingly held in an intermediate centeif ed position.

By reference particularly to Fig. 3, it will be noted that equalizing springs 11, in the preferred arrangement illustrated, are arranged in pairs, one inside and the other outside of the cooperating side frame 1.

The endwise- This gives a wide lateral support for the combined spring cap and roller base 18 and also keeps the springs close to the side frames. Furthermore, this duplex arrangement of the said springs and of the links 7, transmits the weight centrally to the coiled springs 5 and to the truck side frames.

The so-called slides 1a are preferably in the form of castings but may be otherwiseformed. IVhen worn, they may be readily replaced; and furthermore, they permit the bolster, when on its side, to be passed through the openings in the frame and turned to position, without requiring wide openings below the column guide faces. The guide pieces 14 should be inserted after the bolster is in place. Each hanger made up of the solid links 7, might, as is obvious, be made up of a single U-shaped piece. As shown brake hangers 20 are cast integral with the truck side frames, but this is a feature which constitutes no part of the present invention.

The truck, while especially designed as a caboose truck, may, nevertheless, as is obvious, be generally used wherever found serviceable.

\Vhat we claim is:

1. In a car truck, the combination with truck side frames having columns, of combined spring caps and roller bases, springsupported on said side frames, a truck bolster with its ends working between said coluinns, rollers interposed between said bolster, and combined spring caps, and roller bases, and guide pieces carried by said combined spring caps and roller bases, interposed between said columns and bolster and movable vertically on said columns, said bol ster having an cndwise movement, in respect to said guide pieces, transversely of the truck.

2. In a cartruck, the combination with truck side frames having columns, of combined spring caps and roller bases springsupportcd on said side frames, a truck bolster with its ends working between said columns, rollers interposed between said bolster and combined spring caps and roller bases, and guide pieces detachably supported by said combined spring caps and roller bases; interposed between said columns and bolster and movable vertically on said columns, said bolster having an endwise movement, \in respect to said guide pieces, transversely of the truck.

3. In a car truck, the combinationwith side frames having columns, of combined spring caps and -roller bases spring-supported on said side frames, a bolster with its ends working between said columns, lateral motion rollers interposed between said bolster and combined spring caps and roller bases, and channel-shaped guide pieces interposed between said bolster and columns izing springs.

o.- In a car truck, the combination with truck side frames having columns, of front and rear coiledsprings seated on said side frames, elliptical equalizing springs extending longitudinally of said side frames to the front and rear of said columns, hangers carried by said coiled springs and connected to the ends of corresponding equalizing sp'rings,-and a truck bolster working between said columns and carried by the intermediate portions of said equalizing springs.

6. In a car truck, the combination with truck side frames having columns, of front and rear coiled springs seated in openings in said side frames, elliptical equalizing springs extended longitudinally of said side frames, hangers carried by. said coiled springs and connected to the ends of said equalizing springs, a truck bolster carried on the intermediate portions of said equalizing springs, and lateral motion devices interposed between said equalizing springs and bolster.
