UNITED STATES WILLIAM F. KIESEL, JR., F ALTOONA, PENNSYLVANIA.

FREIGHT TRUCK.

Application filed May 17, 1919.

To all whom it may concern.-

Be it known that I, WILLIAM F. KInsEL, Jr., a citizen of the United States, and residing at Altoona, Blair County, State of Pennsylvania, have invented certain new and useful Improvements in Freight Trucks, of which the following is a specification.

The present invention relates to car trucks and more particularly to six wheel trucks for freight cars.

The principal novel features of this invention reside in the improved side frame members; the improved single piece bolster; the improved loose connection between the bolster and side frames, this connection being the sole means for holding the side frames in proper spaced relation; the improved means for holding the central journal boxes against transverse movement, the equalizer bars being utilized for this purpose; and the improved means for supporting one end of the equalizer bars on the side frame members. Other features of novelty will be ap parent from the description taken in connection with the drawings, in which Fig. l is a top plan view of a truck con structed in accordance with the present invention, certain parts of one of the side frames being shown in section to illustrate parts otherwise hidden;

sub- Serial No. 297,722.

Referring to the drawings it will be seen that the truck embodying the present invention comprises the side frame members F and F loosely held in spaced relation by the single piece bolster B. The end axles A and A support the side frames through journal boxes bolted to the under side of said frames. The central axle A has journal boxes at its ends on which one end of each of the equalizer bars E are supported, the other ends of'the bars bein carried by the frames.

As shown the side frames F and F are hollow and substantially rectangular in cross section. The cross sectional shape of the side frames may perhaps be best defined by the term box section. Furthermore, throughout the greater part of their length they are substantially straight. The end portions of these frame members however are tapered and inclined downwardly to a. slight extent. The frame members adjacentthe bases of the tapered portions are supported on the journal boxes 20 of the end axles, these boxes preferably being standard M. C. B. freight car boxes. The boxes are secured to the under side of the frame members by bolts 21, apertures 22 being provided in the bottom walls of the side frame members for these bolts. In order to give access to the heads of the bolts 21, apertures 23 are provided in the top walls of the frame members, these apertures registering with the apertures 22. The ends of the frame members are forked as at 24: and these ends are apertured as at 25 to provide means for supporting parts of the brake apparatus. Furthermore the tips of the tapered ends of the frames are offset so that they are disposed very nearly in the k planes of the wheels of the truck as clearly shown in Fig. 1. The bottom walls of the side frame members are formed with the elongated slots 26, these slots being positioned over the journal boxes 27 of the central axle, for a purpose presently to be described. Adjacent the end boxes 20, the under side of each of the frame members is provided with the hollow, depending proj ections 28. The equalizer bars E each have one of their ends 30 disposed within a projection 28 and this end is formed with an aperture 31 for a key 32, the ends of which are disposed in the registering apertures 33 formed in the side walls of the projections. As clearly shown in Figure 10, the under side of the key 32 is formed with a central.

lug 34, the length of which is substantially equal to the distance between the side walls of the projections 28 whereby the lug 34 holds the key against displacement. The apertures 33 are of greater height than the key, so that the key may be removed by first moving it vertically upward from its position in Figure 10 and then pushing it out laterally through one of the apertures 33.

As shown in Figure 9 the central box 27 is formed with the vertically disposed grooves 35 on its opposite vertical sides and recesses 36 in its top in line with the side grooves. The equalizer bars E are constructed to have one end thereof disposed in the said grooves and recesses. These ends of the bars are also provided with a projection. 37 which is disposed within the slot 26 in the bottom of the frame member. In this manner the adjacent ends of the equalizer bars act as keys to hold the central boxes 27 from transverse movement relative to the side frames.

The bolster is of one piece construction. As shown it comprises the two transverse spring beams 38 of I section. These beams are connected by the longitudinal trusses 39, the latter being offset inwardly from the ends of the beams 38, so that they are disposed just inside of the wheels 40. As clearly shown in Figures 6 and 7 each of these trusses are formed with a recess 41 in its underside for the passage of the axle A A strap 42 is disposed across the mouth of each of these recesses and secured to the under side of the trusses, as by means of bolts 43. The straps 42 are formed with the shoulders 44 which engage on the outside of the lugs 45 at the mouth of the recesses, thus providing a connection between the truss and strap acting to prevent the mouth of the recess from being opened up when the truss is stressed, and thus relieving the bolts 43 from carrying all of this load. The trusses 39 are connected by the transverse girders 46 which are spaced a distance substantially equal to the width of the recesses 41. These girders carrv the center plate support 47 and this plate is reinforced by the diagonal braces 48 extending from the corners of the plate to the junctures of the trusses and the beams 38. As shown in Figure 8 these braces 48 are substantially of inverted U-shape in cross section.

The beams 38 have their outer sides adjacent the ends thereof formed with the vertical channels or grooves 49 to receive the projections 28, thus providing a more or less loose connection between the side frames and bolster to hold the side frames in proper spaced relation. It will be observed, as the bolster is of one piece construction, the channels 49 are provided on one side only of each of the beams 38, the opposite sides having no engagement whatever with the side frames. The trusses 39 are connected'to and extend between the sides of the beams 38, that is to say, the trusses are not secured to the upper faces of said beams. Furthermore the transverse girders 46 are connected to and extend between the adjacentsides of the trusses 39.

The ends of the beams 38 are supported on the equalizer bars E by means of the coil springs.

Although an embodiment of the invention has been described in detail, it is to be understood that the invention is not thus limited, but includes modifications and changes which come within the scope of the appended claims.
