l Application filed February 1, 1906. SerialNo. 299,002.
citizen of the United States, "residing atk Springfield, in theccounty of Sangamon and State of Illinois, have invented a new andl useful Improvement in Car- Truck Bolsters, of which thefollowingis a Specification. y
My invention relates to an improvement in that class of car-truck bolster which is ordinarily composed of cast-steel integral through out, and has for its object to reduce weightand obtain a strong, rigid, and durable bolster.
The invention consists in features of novelty, as hereinafter described and claimed., reference being had lto the accompanying drawings, forming part of this specification, whereon- Figure 1 is a top plan view of a preferable construction of my improved car-truck bol- Ster; Fig. 2, a side elevation thereof; Fig. 3,
, an end view of the same; Figs. 4 and 5, vertical transverse sections through the olster on lines 4 4 and 5 5, respectively, in igs. 1 and 2; Figs. 6, 7, and 8, corresponding views to Figs. 1, 2, and 3 of a modified form of the bolster; and Figs. 9 and 10, cross-sections thereof on lines 9 9 and 10 10, respectively, in Figs. 6 and 7.
Like letters and numerals of reference denote like parts in the respective figures.
Referring to Figs. 1 to 5, a represents my improved truck-bolster, having its body b,
with'the center plate 1, side bearings 2, and
truck-column guide-lugs 3, composed, preferably, of cast-steel integral throu hout. The
olster a seen In the modification of the in Figs. 6 to 10 two truss-bars c are used in lieu of one, as before described., in which case4 the middle portion 4 of the body b is preferably I-shaped in cross-section and the bot- Paten-'ed May e, 190e. l y
tom channels 9 formed only part way along the under side of the bottom flanges at the outeredges thereof and preferably beneath the center plate 1 similar channels 9being formed for the bars c through the end portions 10 of the body b adjacent to their side Walls, as shown, the bars c bearing throughout against the under side of the body b', Which is substantially similar in principle and construction to the body b, previously described,
