UNITED STATES PATENT EETCEQ GEORGE I. KING, OF DETROIT, MICHIGAN, ASSIGNOR TO THE AMERICAN CAR AND FOUNDRY COMPANY, OF ST. LOUIS, MISSOURI.

BODY TRASOM BOLSTEV'R FOR RAILWAY-CARS.

SPECIFICATION forming* part 0f Iiletterslatent No. 658,784, dated October 2, 1900. Original application iiled February Z6, 1900, Serial No. 6 ,534. Divided and this application tiled May 7, 1900. Seri/al Y To a/ZZ whom it may concern:

- Be it known that I, GEORGE I. KING, a citizen of the United States, residing'at the city of Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Body Transoms'or Bolsters for Railway-Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a top plan view of my improved body transom or bolster for railway-cars. Fig. 2 is an elevational view. Fig. 3 is a cross-.sectional view on line 3 3, Fig. 2; and Fig. 4 is an end elevational view.

This invention relates to a new and useful improvement in body transoms or bolsters for railway-cars, the object being to construct a device of the character described in a simple and compact form and at the same time preserving the strength which is required `of structures of this character.

With this object in view the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

The bolster shown in the accompanying drawings is illustrated in an application for patent for hopper-bottom car, led by me February 26, 1900, Serial No. 6,534, and this present application is divided from the parent case.

Generally speaking, the bolster consists of a casting, preferably steel, made deepest at its middle portion and strengthened to best take care of the strains to which it is subjected. The casting forms, substantially, the compression member of a trussed structure, the center sills acting in the capacity of struts, while a cover-plate serves as a tension memi ber, said cover-plate being riveted to the flange of the bolster proper and terminating short ofthe ends ot' the bolster.

The body portion of the bolster in the form of a casting is marked 7 6 in the drawings and observes a general cross-section of I-beam form, one otl its characteristics being that a squared (No man.)

i recess 90, open at its top, is provided at about theenterof this casting, and against the flanges forming the side Walls of said recess are received and secured by suitable rivets the channel-beams 49, forming the main members of the center sills. The usual center bearing 91 is provided on the lower face of the bolster, while the structure above this center bearing and between the beams 49 is strengthened by a bulge or crown 92, which also forms abutting shoulders, against which rest the lower flanges of the beams 49.

93 indicates the side bearings, formed integral with the bolster and which, as usual, are located directly above the side bearings of the truck-bolster.'

The central web of my improved bolster is cut away at convenient pla-ces .for the purpose of lightening the same, and strengthening-ribs are provided at convenient points Where the middle web is left for well-known purposes. I have arranged these ribs vertically, as at 94, immediately above the side bearings to strengthen the structure at this point, while diagonal ribs 95 extend from the junction of the flanges at the upper corners of the middle pocket to the junction of the vertical ribs 94 and the bottom lateral flange of the bolster. The vertical web of the bolster is preferably extended beyond itsbottom flange for the purpose of strengthening the same. The ends of the bolster are broadened and formed with elongated vertical walls 96, which are shaped to snugly receive the angle-bars 16 and 17, forming the side sills, which are riveted thereto. The hori- 'Zontal anges of the bar 17 are further supported by the horizontal shelf-like projections 97, extending from the ends of the bolster therebeneath. These projections 97 are strengthened by vertical Iianges 98, the same being continuations of the central vertical web of the bolster.

77 indicates the cover-plate, to which I have referred above, said cover-plate being sub'95 stantially diamond-shaped in plan View, the broadest part bridging the squared recess 90, while the side edges converge toward the casting, the ends of said cover-plate terminating short of the ends of the bolster. Rivets IOO affords attachment for the licor-supports.`

(Not shown in the present application.)

Having thus described my invention, what I claim, and desire lo secure by Letters Pat-l ribs 94 and the bottom lateral flange of the ent, is-

l. In a body-bolster, the combination with a casting whose upper face is liush with the center and side sills throughout the width of the carto serve as an unbroken floor-support between the center and side sills, saidv upper face bein;r formed with a recess at about its center for receiving the center sills, and serving as a compression member, of cen* ter sills arranged in said recess and serving as a strut, and a cover-plate bridging said recess and extending some dist-ance therebeyond, said cover-plate being riveted 1o the upper liange of the bolster and serving as a tension member therefor; said cover-plate also offering a licor-support of considerable area which extends lsubstantially across the bottom of the car, substantially as described.

2. The combination with a body-bolster formed with a recess in its upper face for the reception of the center sills, of a tension member in the form cfa cover-plate bridging said recess, and an angleplate for reinforcing said cover-plate tension member; substantially as described.

3. The herein-described body-bolster provided with a squared recess 90,-open at its top, for receiving center sills, an integral center bearing on the lower face of the bol-` ster, and a bulge or crown 92 above said center plate and between the lower ends of the center sills, whose inner edges abut thereagainst; substantially as described.

4. The herein-described body-bolster substantially of I-beam cross-section throughout, of integral side bearings depending from said bolster, the central web of the bolster being cut away at convenient places for the purpose of lightening lthe same, vertical ribs 94 arranged above the side bearing, and diagonal ribs 95 extending from the junction of the lianges at the upper corners of the middle pocket tothe junction of the vertical bolster; substantially as described.

5. The herein-described body-bolster substantiall y of I-beam cross-section throughout its length, the vertical web of the same eX- tending beneath the bottom flange, the ends of said bolster beingbroadened and formed with elongated vertical walls 96 shaped to receive ythe side sills, and horizontal shelf-like projections 97 extending from the ends of the bolster, said projections being strengthened by vertical ianges 98, said vertical flanges being continuations of the central vertical web of the bolster; substantially as described.

6. The herein-described body-bolstersubstantially of I-beam cross-section throughout, the central web of said bolster being,r cut away at convenient places for the purpose of lightening the same, vertical ribs connecting the top and bottom lianges of the bolster, and diagonal braces or ribs; substantially as dcscribed.

In testimony whereof I hereunto aix my signature, in the presence of two witnesses, this 26th day of April, 1900.

GEORGE I. KING.
