CAR-BOLSTER.

To f/,ZZ whom, it Imay concern.'

Be it known that I, ETHAN I. DoDDs, a citizen ofthe United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Bolsters, of which the following is a specification.

My invention pertains to car-holsters; and its principal objects are the production of such a structure which shall provide great strength, which shall be comparatively economical in the cost of manufacture, and the depth of whose sides may be varied to some extent. The bolster has its bellied sides integral with the bottom plate at its central portion, and at the intermediate inclined and horizontal endportion of the sides the bottom is riveted to inturned flanges integral with the sides. At the upper portion of the sides Irivet angle-bars with outwardly-extended flanges, to which may be secured a top plate. In addition, if desired, I may connect the upper parts of the side plates by achannel-bar riveted thereto.

In the accompanying drawings I have illustrated two embodiments of my invention, whcrein- Figure 1 is a longitudinal vertical central section of a body and truck bolster both embodying my invention. Fig. 2 is an enlarged end view of' the two bolsters as shown inFig. 1. Fig. 3 is an enlarged cross-section on the i lint,` 3 3 of Fig. 1 as viewed in the direction indicated lby the arrows.. Fig. 4.- illustrates the blank `from which the body-bolster is constructed. Fig. 5 illustrates a similar blank from which the truck-bolster is constructed, and Fig. (j is a perspective view of a modified l'orm of truck-bolster.

Inaslnuch as both bolsters are made from blanks which are similar in all respects, a description of the body-bolster blank shown in Fig. 4 will suIIice for both constructions.

'lhc body-bolster is made from a rectangular sheet of metal by cutting inwardly from each end two parallel cuts on the lines 11 l2. 'l`he sheet is then shcarcd on the lines 13 14 and 14 l5, four of each of these cuts being made, :is shown in Fig. 4, the point 15 where the line 14 15 meets the line 11 1-2 being some distance from the point 12. By means of tht-,sc cuts two tapering iecespf metal are removed from each end, eaving the four recesses shown on the drawings.

` as the body-bolster.

Patented .Tiny 3, 1906.

In order to provide integral flanges for portions of the lower edges of the parts which areto com rise the side plates of the bolster, I bend up t ie flanges 16 on .the bent lines 17, the same extending from points 12 to the ends of the bolster. The outer longitudinal portions 18 of the sheet'lO, which are to form the sides of the bolster, are then foldedy upon the lines 19 19, joining the points 12 12,' so that the sides will be at right angles to the central bottom portion 20. The central strip of the sheet which forms the bottom of the bolster is then bent on the transverse lines 21, so that the portions 22 will be inclined and lie against the inclined ortions of flanges 16. The central strip is a so bent on the lines 23 to provide the end horizontal portions 24 of the bottom, so as to lie against the horizontal portions of the flanges 16. When the bolster is thus formed to shape, the bottom is riveted to the integral side flanges 16, as shown in Fi s. 1, 2, and 3.

It will be evident from this escription how the main portion of the truck-bolster is made, since it is constructed identically asset forth above and differs from the body-bolster only in respect to size.

Adjacent to the upper edge of each side of the body-bolster I rivet the angle-bars 25, with their flanges extendingvoutwardly, the bars being substantially the same length As spacing means for the ends of the bolster I provide dish-shaped members 26, with their flanges extending outwardly, the same being riveted to the sides and bottom'of the bolster, the rivets passing also through the angle-bars 25 and the flanges 16. To these upper outwardly extended angle-bars I rivet a top tension-plate'27, as is shown in Figs. 1 2, and 3. The angle-bars.

28, secured to the sides of the truck-bolster,

extend over only a part of the length of the bolster, as is shown'v in Fig. 1, and to these angle-bars I rivet a compression-plate 29. At the ends of the bolster the dish-shaped members 30 act as spacing means to hold the sides apart and at the saine time join them together, these members being riveted to the sides and bottom of thefbolster, as shown in Figs. 2 and A3. It will be clear that these upper angle-bars-may be fastened to the sides, so that their outwardly-extended flanges would be some distance above the upper edges of the sides. By 'so doing I may vary the depth of the sides 'of the bolster and IOO strength of the same and am 'enabledto use a standard size bolster for cars which require such structures of different strengths or depths. The strength of the bolster may also be varied by using angle-bars of differ` v' tending upwardly and riveted to the sides portion of its len ing said outwardly-extended flanges,

adjacent to their upper edges. It will be seen from this construction that I secure an especially 'strong/structure, since the integral flan es of this channel-bar 31 are riveted di` rect y to the sides. y

While I have herein shown and described the preferred embodiments of my imprevements, it isl to be understood, however, that the details may be modified without departfrom the invention, and accordingly I d'o not limit myself to these details, except to the extent that they are made the subjectmatter of specific claims..
