Description
V. WILLOUGHBY ETI" AL RAILWAY CAR UNDERFRAME Filed Nov. '7, 1931 Dec. 5, 1933.
Patented Dec. 5, 1933 v RAILWAY CAR UNDERFRAME Victor Willoughby, Ridgewood, N. J., and Robert W. Joy, Brooklyn, N. Y., assignors to American Car and Foundry Company, New York, N. Y., a corporation of New Jersey Application November 7, 1931. Serial No. 573,646
k3 Claims. (C1. M15- 414)- side sills of the ear underframe by means of aV relatively channel-shaped diagonal brace `which is flattened at one end for connection with an end and side sill and yis somewhatI widened and v flanged at its opposite end for direct connection with draft sills.
l0 Referring to the accompanying drawing, Fig. y
l is a partial plan View of an end portion of a car underframe broken away at one place for better illustration of details; y
Fig. 2 is a longitudinal vertical sectional view taken on the line 2-2 of Fig. 1; and v Fig. 3 is a transverse sectional view'taken on the line 3 3 of Fig. 1.
Referring to the parts, 4 indicates a bolster which may be of conventional form. 5 indicates the bolster center iillercasting which is connected directly to draft sills or center sills 6 and is provided with longitudinal extensions 7 shown in full lines at the broken portion of Figjland in dotted lines attached to the opposite draftsill of the same gure. It has been common practice to provide diagonal braces connecting side and end sills with draft sills. However, in the present instance the diagonal braces indicated by reference character 8 are employed for the additional purpose of connecting the end sill, Aside sill, center sill or draft sill and the longitudinal extension 7 of the bolster center filler casting, in addition to which the present invention relates to means whereby the diagonal brace is better adapted to resistrend thrust than if it were flattened at both ends as shown 'where it is connected with the side and end sill. the diagonal brace 8, has the web and at least one of its flanges, 9a in the instance shown, deflected from the longitudinal plane of the brace to-form a vertical flange 9 which parallels, con'- tacts with and is riveted directly to the draft sills or center Vsills 6 as best shown in Fig. 3 by means of the rivets. 10. 1t will be obvious from an inspection of Fig. 1 that the diagonal brace which is of general channel shape in cross section is widened at 8 adjacent the vertical flange 9,`
thereby affording an extended attaching portionwhere it joins the center or draft sill 6.
From the middle portion of the diagonal brace 8 towards the juncture of the side and end sill the diagonal brace is formed considerably wider than at the middle of its length and is pressed upwardly as best shown in Figs. 2 and 3, thereby y forming stops 8a which, in additionto bracing To this end the connection at the side and end sills, serve as positioning meansl to` facilitate placing the diagonal brace in proper position 4with relation to saidside and end sills beyond which the ydiagonal brace is flattened as shown best at 12 in Fig. 2. 'l
vWhat is claimed is:
y1. In a car underframe, a draft sill, an 'end sill, a side sill, and a diagonal brace extending from the draft sill tothe juncture of thejside sill and end sill and directly connected to saidsills,theend portion of the brace at the draft sillbeingwidened Y and having a deflected portion providing a ver@ tically arranged attaching Vflange engaging and 7 secured rto the draftV sill. 0 K l 2. As an article ofmanufacture, a brace mem-l ber for car underframes comprising'fa one piece channel member having its flanges adjacent one end portion merged with the web to. providea relatively wide attaching portion,'stop members 75. -4
formed at the attaching portion, -the opposite end portion of said` channel member A'having its Weband at least one of its side flanges deflected in such a manner as to provide a relatively deep vertically arranged attaching flange. f 80 3. In a car underframe, a bolster, side anden sills, a bolster center ller casting, a draft sill lapping the center filler casting, and meansfor stiifening the underframe comprising a downwardly facing channel member having itsflanges adjacent one end portion deflected into the plane of the webto provide a relatively widelattraching portion extending across the juncture of the side and end sills and secured to both thereof, stop members formed integral with said channel mem-
