Application ned August 24, 15975 To ctZZ whom if vnu/y concern:

Be it known that I, HENRY TEssEYMAN, a i

ton, in the county of Montgomery and State ful Improvements in Truck and Body Bolsters for Freight and Passenger Cars; and I do hereby declare that the following is a full,

My invention relates to improvements in truck and body bolsters for freightv and passenger cars, its object being to so construct such bolsters as to reduce the cost thereof and increase their durability, andwith such ends in view'the invention consists in certain novel claims, and shown in the accompanying drawin Which- Figure 1 is a broken perspective'view of theV invention, showing the relative positions of the two bolsters and 'the floor-sills of a carV mounted onthe' body-bolster, one half being shown in full and the other halfA in section through the longitudinal center of the bolsters; and Fig. 2, a broken perspective view the separate sections of the transom-bolsters are united.

Similar letters and figures indicate corresponding parts in the drawings.

Each bolster is composed principally of two iron or steel channel-bars A and B, the top bar A of the upper or body bolster being straight and the lower bar B being so formed center it is parallel with the top bar, and then angles upwardly from the center to the end parallel portions, while both sections 'fof the lower or truck bolster are formed like the lower section of the body-bolster. The edges of the side flanges 1 of the channel-bars are brought together, Ornearly so, at their ends, where the two sections are firmly bound together by filling-blocks O, preferably cast and cored out on the insideto reduce their weight, in the manner hereinafter explained. On the top and bottom of these blocks are formed an- -shown in Fig. 2.

nular collars or bosses 2, and on two opposite Serial No. 649,318. (No model.)

ltion of theV ribs being to contribute strength to the hollow structure, through which holes 6, 7, and 8 are cored or bored,'as more clearly One of the filling-blocks is placed between the sections at -each end of the bolster, the sides 1 of the channel-bar sections overlapping two sides of each block. Holes 9 are pierced through the iiat surface lO vof each of the channel-bar sections to engage the annular collars 2 of the filling-blocks, and the'side anges 1 are cut away to engage and to coact with the lugs 8 in resisting the end strain on the saidside anges..

The side sills of the car-body are represented by the letter D and the intermediate sills' by the letter E, and they rest on the body- 'bolster as shown.

Bolts 11 extend from the under side of the 'of each bolster VVbetween the ends thereof and which are bound firmly together by bolts 13, 14,' and 15, the bolts 13 passing up through `the sections, the distance-posts, and the outside intermediate sills, while the bolts 14 perform the same function in connection with the two center sills and the further function of securing a center-bearing plate G to the Vunder side of the body-bolster, and the bolts 15 extend through the two sections of the truck-bolster, the intermediate posts F thereof, and through a center-bearing plate H,

mounted on the upper side of the bolster, and bind the said parts firmly together. The center bearing is composed of two parts I J, which are of usual construction. An ordinary kingbolt K passes through both bolsters and IOO through the center bea-ring in the customary manner.

Side bearings L M are secured to the bolsters, as shown in Fig. l, although they may be otherwise constructed and arranged, as may also the center bearings, on which the body bolster rotates. The usual form of chafe-plates are bolted to the sides of the truck-bolster, at the ends thereof, by bolts which extend through the holes 8 in the filling-blocks.

It will be observed from the foregoing description of my improved bolsters that they are of simple construction and of light weight in proportion to their required strength.

Having thus fully described the invention, I claiml. A bolster for railway-Cars consisting of two channeled sections bent to desired shape, filling-blocks located within said sections, at the ends thereof, bosses formed on the top and bottom of said filling-blocks to engage corresponding holes in the fiat surfaces of said sections, and meansfor rigidly securing said sections to said filling-blocks, substantially as set forth.

2. A bolster for railway-cars consisting of two channeled sections bent to desired shape, filling-blocks located within said sections, at the ends thereof, bosses formed on the top and bottom of said filling-blocks to engage corresponding holes in the fiat surfaces of said sections, means for rigidly securing the fiat surfaces of said sections to said fillingblocks, and lugs or bosses formed on opposite sides of the latter to engage cut-outs in the side fianges of said channeled sections, substantially as set forth.

3. In truck and body bolsters for railwaycars, the combination of a truck-bolster and a body-bolster, each composed of two channeled sections bent to desired shape, fillingblocks located within said sections at the ends thereof, bosses formed on the top and bottom of said filling-blocks to engage corresponding holes in the fiat surfaces of said sections, means for rigidly securing said sections to said filling-blocks, and side and center bearings located between said bolsters, substantially as set forth.

4. In truck and body bolsters for railwaycars, the combination of a truck-bolster and a body-bolster, each composed of two channeled sections bent to desired shape, fillinghlocks located within said sections at the ends thereof, bosses formed on the top and bottom of said filling-blocks to engage corresponding holes in the flat surfaces of said sections, means for securing the flat surfaces of said sections to said filling-blocks, lugs or bosses formed on opposite sides of the latter to engage cut-outs in the side anges of said channeled sections, and side and center bearings located between said bolsters, substantially as set forth.

Vitn ess my hand to the foregoing specification on this 21st day of August, 1807.

HENRY T SSEYMAN.
