Attest UNITED STATES PATENT OFFICE.

JOHN M. GOODWIN,,OF MOUNT VERNON, NEW YORK.

'- TRUCK-EOLSTER.

To all whom it may concern;

Be it known that I, JOHN M; GOODWIN, a citizen of the United States, and a resident of the city of Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements tion which will properly transmit the Weight of the vehicle' to the vehicle-wheels without distortion or; appreciable flexure; and the invention involves the several features of construction and arrangement of parts, as will be hereinafter fully. described, and more particularly pointed out in the appended claims- Referring to the drawin s, which form a part of this specification, igure 1 is a top plan view of a bolster embodying my inven tion. Fig. 2 is a side elevation thereof. 3 is a vertical transverse section on line 3 3 of Fig. 1. Fig. 4 is a horizontal section on line 4 4 of Fig. 2. Fig. 5 is a side elevation ofa modified form, and Fig. 6 a horizontal sec tion'online66of Fi .5.

Referring first to 'igs. 1 to 4, the bolster is formed of two longitudinal side sections 1 and 2, which in this form of the invention are formed of heavy sheet metal and rovided an bottom fastened together at a fixed and referably uniform distance from each other y means of a top bindinglate 3 and a bottom binding-plate 4, these inding-plates being shaped to conformto the-desired contour of the side sections and firmly secured to the margins thereof by means of the angle-irons 5, above referred to At each end the bottom bindsuitably fashioned to rest upon the ing-plate 4 is provided with a bearing-seat 6,

earin of the side or suspension frames of the truc and the top binding-plate is also provided with a cap-plate 7 verticall above the said bearing-seat, these parts cing riveted or otherwise secured, respectively, to the top and bottom lates, as clear] shown in the drawings.

Specification of Letters Patent.

/ Application filed January 4,1906. Serial No. 294,522. a

which surrounds the king-pin.

he hollow boxike beam thus Patented March 27, 1906.

. formed is reinforced at its central portion,

where the pressure of the load is intended to be applied to it, by means of a filler-block or rigid part substantially filling the entire central portion of its interior. or having bearing engagement with the walls thereof. This filler-block is susceptible of different structural formations; but, as shown in Figs. 1 to 4, it is comprised of two projections 8 and 9, respectively, formed on 01' secured to the opposite interior walls of said beam or bolster, the two projections together constituting the said filler block or stiflening means. As shown in Figs. 1 to 4, the projection 8 is made selparately and secured to the side section 1, w 'le projection 9 is secured to the side section 2, andthe proximate faces of said projections are formed with complementary contours, so thatthe two will interlock or rabbet together. The two projections are equal in height to the height of the side sections, so that theyform post members between the top and bottom binding-plates, and the lateral bolts 10' pass through the side sections and both pro ections to secure them in lace and aidin holding the side sections rmly together; but" the projections may be provided with flanges, as shown at 8, by means of whichfthey may also be secured to their side sections. One or the other of the projections may be recessed to receive the swivel or kin -pin of the truck; but, as shown herein,

the ingin aperture is provided by forming a vertica recess or oovein each of said members, and the sai recesses when the projections are put together form a vertical cyindrical king-pin aperture. The top binding-plate 3 is apertured at 11 in registry with the said king-pin aperture, and a bearingplate 12, provided with an annular dependmg-boss 13, is secured to said top plate, with its said boss protruding through the aperture 11 and resting'against the bottom of an annular rabbet-slot in the upper end of the filler block. The bearin -plate 12 is 'firmly secured to the top bin ing-plate and has its upper surface concaved to support the convex protuberance from the car body bolster, (Not shown.) For economizing metal and reducing weight the projections or members 8 and 9 of the filler-block may be cored out, as indicated in Tieferrin now to Figs. 5 and 6, the invention is exhi ited in a modified form in which the bolster is still hollow-that is to say,

formed of upright side sections 13, fastened together at a distance from each other top and bottom bindinglates; but the sald s1de sections in this modi cation are respectlvely 5 cast or forged integrally with the inward or interior pro'ections 14 and 15, which constitute the 'er-block. The said projections interlock by a rabbet connection, and transverse bolts serve to hold them together. Porro tions of the rojections are also cored out for the sake of 'ghtness, as indicated in Fig. 5. In this form of truck the side sections are provided with vertical channels 16 at their ends, which serve as column-guides for the I 5 ends of the bolster in the side frames of the truck.

In both forms of the invention shown it- Will be observed that the pressure and strain exerted by the king-pin is borne in the first 2o instance by the filler-block and by it transmitted to the .body ortion of the bolster and also ,that the said ffiler-block, in addition to its function of a guide or socket for the kingpin, serves as a strut which converts the top and bottom binding-plates into the top and bottom chords of a truss for withstanding the vertical pressure upon the bearing-plate 12, thereby increasing the rigidity and resistance of the device to the superimposed load. -Having described my invention, what I claim, and desire to secure by United States Letters Patent, is-

1. A truck-bolster composed of side sections fastened together at a distance from 3 5 each other, in combination with means filling the space between the central portions of sai side sections and provided-with an aperture adapted to receive the king-pin.
