SPECIFICATION forming part of Letters Patent No. 537,076,'dated April 9, 1895. Application led October 23, 18.94. Serial No. 526,742. (No model.)

To LZ Z,wZ1.0m it may concern.-

Be 1t known that I, CHARLES T. SCHonN, a

Y citizen of the United States, residing atAllegheny, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Bolsters or Transoms, of which the following isa full, clear,

and exact description.

The object of this invention is to produce from sheet or plate metal, preferably soft steel, -by pressing or otherwise, bolsters or transoms for railway cars and the like. l

In practice, I have found that bolsters hav ing straight sides are of barely sufficient rigidity and stiffness to resist the strains incurred under all ordinary circumstances, and very seldom or never capable of resisting such vstrains under extraordinary conditions; and

in a built-up or composite bolster constructed of two main pieces united by tie-pieces, there are necessarily many rivet holes and rivets employed, themselves being elements of weakness in the structure; and the rivets having to be applied hot, additional cost of material those of Wood, and also to admit of the use of steel holsters orv transoms on the ordinary MasterCarBuildersstandarddiamond-frame trucks,fl provide for the variations in height at the points where the center-bearing plate is applied and where the spring-plates arensed, by building up these point-s with added` pieces of metal. Now, with these facts in mind, my invention maybe stated to consist of a pressed steel bolster or transom formed integrally with a solid dat face, side lianges and returnanges at their edges, the sideA flanges being widest atthe center of the bolster and 'decreasing in width toward both ends Yof the bolster, and pressed steel spacing plates disposed at'points thereon necessary to my invention as applied to a ytruck bolster or A transom for railway cars, in the several tigures of which drawings like parts are similarly designated, Figure l is a side elevation.

Fig. 2 is a top plan view. Fig; vSis a cross-` section at 3-3. Fig. 4t is a crosssection at 4-4, and Fig. 5 is an elevation at the end.

As shownvmost clearlyin Figs. 4 and 5, the

truck bolster or transom is iliade with a flat bearing surface,n face or top a, side flanges b, which are widest at the point of greatest `nary as ordinary strain. The return flanges c extend, by preference, from end to end. A bolster or transom thus constructed has been demonstrated to meet practically all the requirements of the strainsto which it is subjected in use.

The several parts ofthe body being integral,

admitnot only of. its being produced economically and quickly by the present well-known methods of pressing steel plates, but in addition insures a homogeniety in the article which greatly augments its endurance or capacity.

Wooden holsters are cutaway at their ends Y holsters with such wooden bolsters, or to adapt them to diamond frames, I provide for variations in height by building up the holsters at the desired point or points by the addition of metal spacing plates of the proper height. Such plates are shown at d for the centerbearing plates, and at e,e, for the'springplates, the said spring plates themselves not beingshown. The spacingplates d are made with end flanges d', by means of which they may be riveted or otherwise fastened to the body, and with an intervening elevated seat d? to receivethe center-bearing f, and this elevated seat is provided with a central transverse depressi-on cl3 to stiften it and to admit IOD e for fastening them to the return'anges c,-

and with the elevated seat e2, the edges of which may be provided with pocketses, o r a transverse depression, sllch as that designated d3 in the plates d, to recevefastening devises.

The plates d and e are mmade by pressing np.

the same from flat, steel plate. t

Holster solemn-guide plates it are shown as of the consti-notion set forth in `my Ytannini rent patent, No. 529,809, granted November 27, isnt.

Asalready indicated, holsters ortransoins may be oonstrueted in aeeordanee with this invention by pressing 'them np from steel er other plate instal, in e veryeeonomieal manner, and such beams possess great 'strength 'or endurance in meeting 'beth eompreesi've and tensile strains.` g

I do not limit my invention to bblsteis or transoins fon trucks, for obviensly ii .may he usediior bodies as Well.

1. As an improved arti-oie of manufacture,

s pressed steel bolster or transom having an integral solid, tlat face, side flanges and return ilanges at their edges, the side flanges being Widest at the center of the bolster or transom and decreasing in width toward b'oth ends of the bolster or transom, and applied pressed steel spacing plates arranged upon such bolster or transom at points thereon required to be built up to arbitrary standard heights, substantially as described.

2. A metal bolster or transom, combined with spacing-plates having end lian ges and an intermediate transverse depression, and applied to the bolster or transom to gain propel' elevations on the said bolster or transom for the application ofusual appurtenances, substantially as described.

3. The spacing-'plate herein described,hav ing end iianges, a eentrai depression and an intervening relavated l'seat, and adapted for jnse fin bending nip bolstersoitransoms and 4the like tor 'the reception oi the center-bearing plate and the spring-plates, substantially as specified. p l p 4. The combination ol? the bolster or transom, a een-trai spacing-plate, a center-bearing plate applied to enen spaeingplate and end spacing=platesior the reoeption `of the springlares, the several spaeingplates having end anges, a eentral depression and an intermediateelevareu seat, substantiallyas described. in testiinoilyivlleieoi I have hereunto set nl'y hand 4this 13th day of Oetober, A. D. 1894.
