MORSE B. SOHAFFER, OF LOUIS, MISSOURI, ASSIGNOR TO THE AMERICAN STEEL BODY DOUBLE BOLSTER COMPANY, OF SAME PLACE.

CAR BODY BOLSTER.

SPECIFICATION forming part of Letters Patent No. 640,827, dated January 2, 1900.

Application filed October 30,1899. Serial No. 735,277. (No model.)

T 66 whom it may concern.-

Be it known that I, MORSE B. SCHAFFER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a new and useful Improvement in Car Body- Bolsters, of which the following is a specification.

This invention relates to an integral bodybolster for railroad-cars, and is an improve- IO ment on the body-bolster for which I obtained Letters Patent in the United States, dated June 6, 1899, No. 626,445, for an improvement in car-transoms.

This invention has for its object to increase 1 5 the rigidity of the body-bolster and to insure a positive and uniform distribution of the strain of the draft-gear thereto.

The invention consists in features of novcity, as hereinafter described and claimed,

reference being had to the accompanying drawings, forming part of this specification, whereon- Figure 1 represents a transverse section through the sills of a railroad-car with my improved body-bolster, shown in side elevation, applied thereto; Fig. 2, a top plan of the body-bolster; Fig. 3, a longitudinal vertical section through the body-bolster and transverse section through the car-sills on line 3 3 in Fig. 2 5 Fi 4t, a transverse section through the body-bolster longitudinally to the car on line 4: 4. in Figs. 1 and 2; Fig. 5, an end elevation of the body-bolster as seen from the side of the car, and Fig. 6 a transverse sec- 5 tion through the body-bolster longitudinally to the car on line 6 6 in Figs. 1 and 2.

Like letters and numerals of reference denote like parts in all the figures.

My improved body-bolster A is composed 0 of two horizontal side plates to, which are arranged transversely to the car at a suitable distance apart and bear against the under sides of the inner car-sills l 2 3. The side plates a are united at their ends by plates 1),

which are at right angles to the side plates a and in the same horizontal plane therewith and bear against the under sides of the side sills at, the plates 0. and 73 forming a rectangular-shaped frame which practically corresponds to the top plate or arch-bar of an. or-

dinary car body-bolster,

Midway between the side plates a and parallel thereto, respectively, is a beam or girder 0, arranged transversely to the car and united at its ends to the end plates 1). The girder c at its middle portion bears at the top against the under sides of the inner sills l and is preferably I-shaped thereat in cross-section, having the top and bottom flanges 5, vertical central web 6, and terminal walls 7, which unite with the top and bottom flanges 5 and web 6 and preferably extend therefrom across the spaces between the girder c and the side top plates to and beneath the latter, to which they are united and serve as braces thereto.

Through the center of the middle portion of the girder c is formed the vertical hole 01 for the king-bolt, (not shown) and beneath the bottom flanges 5, around the hole (Z, is formed the center plate 6 for engaging the truck-bol- 7o ster in the usual Well-known manner.

From the end walls 7, respectively, of the middle portion of the girder c extend, preferably, two parallel vertical webs 8, the upper edges or surfaces whereof are horizontal and preferably in the same plane as the corresponding surfaces of the top flanges 5 of the middle portion of the girder c and the side and end top plates a Z) and bear against the under sides of the car-sills 2 3, the bottom edges or surfaces of the webs S inclining upward or diminishing in depth from near the end walls 7 to the junction of the webs S with the end top plates b; or in lieu of two webs 8, as shown, one web only or more than two webs may be used. The webs 8 are united to the adjacent side top plates Ct, respectively, by vertical braces or strengthening-ribs 9, disposed along the body-bolster A beneath the car-sills 2 and a or otherwise, as desired. Immediately beneath the car-sills 3 the webs 8 are united at the top by cross-bars 10, which correspond in width to and bear against the under sides of the car-sills 3, respectively. From the cross-bars 10 the webs S incline up- 5 Ward at the top toward the side sills 4, where they project above the end top plates b and are united thereat to each other and to the plates 1) by vertical. cross-bars 11, forming lugs, which butt against the inner sides of the mo side sills e and serve to strengthen the parts and check the end thrust of the body-bolster.

hole d and constitute the side bearings of the.

body-bolster A.

Between the end walls 7 of the middle portion of the girder c and the central hole 01 for the king-bolt are two parallel webs or walls 14, which intersect the vertical web 6 at right angles thereto and unite with the top and bottom flanges 5. The webs or walls 14, which are opposite to each other at an equal distance, respectively, from the central hole 01 extend from one side of the vertical web 6 across the space between the girder c and the" corresponding side top plate a and beneath the latter to a suitable distance beyond its outer edge, where they are united, preferably at the bottom, by a floor 15 and at the rear by. -a vertical web or partition 1 6, which is united 5 at the top to the said plate a; or in lieu of the floor 15 these extended portions of the walls 14 may be closed at the top only, or they may be left open at the top and bottom, asdesired.

On the inside faces, respectively, of these ex-.

tended portions of the walls 14 are formed two vertical lugs 17, the whole forming a pocket at for receiving and guiding the strap draw-bar f, with its followers g, springs h, and draw-bar bolt 2', of the ordinary-coupler draw-bar, as indicated by broken lines, in a similar manner to the separate castings, with their lugs and guides, now usedfor that purpose and which have hitherto been bolted to the ordinary draw-timbers. The walls of the pocket at are preferably braced at the top by horizontal flanges 14', which unite the said walls externally to the outer edge of the top plate aadjacent thereto, the upper and under sides of the flanges 14 being flush with the corresponding sides of the said plate. The walls 14 extend from the other side of the vertical'web 6 across the space between the girder c and the corresponding side top plate a and terminate beneath the latter, as in the case of the end walls 7 of the middle portion of the girder 0. These extended portions of the walls 14 are united beneath the said plate a by a vertical web 18, which may be connected to the corresponding web of the body-bolster at the other end of the car by the bolt 19, as indicated by broken lines.

In case it is desired to use the ordinary draw-bar springrpocket attached to the drawtimbers in the usual manner in lieu of the draw-bar spring-pocketzr, as above described,

the draw-timbers may be inserted within the recesses y, formed, respectively, in the body-bolsterAbetween the extended portions of the Walls 14, inclosing the pocket rand the corresponding parts of the end walls 7 of the middle portion of the girder c, as indicated by broken lines, in which case the rear ends of the draw-timbers 70 will butt against the vertical web 6 of the girder 0.

Through the side top plates a and end top plates 1) and through the top flanges 5 and bearing-bars 10 of the girder c are formed holes 20, which are suitably disposed for receiving the bolts (not shown) by which the body-bolsteriA is secured to the car-sills. Similar bolt-holes 21 are formed through the strengthening-flanges 14 of the pockets m for receiving the bolts (not shown) by which the flanges 14 are secured to the corresponding car-sills 1 and by which, in conjunction with the bolts through the corresponding holes 20 of the top flange 5 and top plate a, the draw-timbers 7c are secured to the sills 1 when the draw-timbers 7t are used in lieu of the pocket 03, as before mentioned. Holes 22 are also formed through the walls 14 and 'through the opposite extended portions of the end walls 7, respectively, for receiving the bolts by which the draw-timbers 70, when used, are secured within the recesses 'y.

The body-bolster A, with the combined draw-bar spring-pocket and all the various parts formed and arranged substantially as hereinbefore described, is made integral throughout and preferably of cast-steel, the whole forming a rigid and durable structure.

If desired, the parts composing the draw bar spring-pocket a:to wit, the extended portions of the walls 14, with its floor 15, connectin g web 16, lugs 17, and strengthening-flanges 14may be dispensed with and the bodybolster used alone in the usual manner.

I do notlimit myself to the specific configuration and disposition of the parts composing the girder c as shown on the drawings, as these may obviously be modified without departure from my invention.

By this invention the strain of the draftgear is distributed through the entire bodybolster and thence through all the car-sills uniformly, thereby steadying thecar and preventing undue and irregular strains thereon.

Also by dispensing with the separate parts of the ordinary draw-bar spring-pocket and their attachments to the draw-timbers and combining these parts in a single piece the construction of the pocket is simplified and rendered rigid and durable.
