1,030,755, Specification of Letters Patent.

To all whom it may concern:

Be it known that we, CHARLES T. WEST- United States, residing at St. Louis,"Mis souri, have invented a certain new and useful Improvement in Car-Underframes, of

which the following is a full, clear, and eX- act description, such as will enable others skilled in the art to which it appe'rtains to 'make and use the same, reference being had tothe accompanying drawings, forming part of this specification, .in which- Figure 1 is-a planview of an underframe of our improved construction. Fig. 2 is a longitudinal section taken approximately on line 2-2 of Fig. 1. Fig. 3 is an enlarged horizontal section taken through a portlon of the bulling sill at the point where one,of the vertical end posts is attached. Fig. 4 is an enlarged cross section taken approxil' mately on line 4-4 of Fig. 1.

This invention relates to that type of'un derframes wherein a double body bolster, 'a'

latform frame and a bufling beam are comined preferably in a single cast-ing and the type of underframe herein shown and described is particularly adapted for, use in connection with blind end cars, although our invention is, -of course, not confined to this particular type of cars. y

Our invention is particularly designed to meet the requirements of .a construction where it is desirable to increase the strength of old cars by the application of a steel underframe and strong vert-ical end posts.y Ordinarily in the re-building or repair of old cars the end posts can only be applied to the car body by permitting the rear flanges of said posts to 4bear against the outer faces of the end sill so that said posts extend approximately or 12 inches out-ward from the end sill, and 'at ltheir upper ends said posts project bey'ondthe old hood or end or top portion of the car, thus necessitating the replacing of the hood which involves considerable labor and material and expense.

Our invention 1s deslgned to overcome t the objection just noted, and the end sill of rear portion of the end sill, and thus the outer flanges or edges of 'said endposts do notproject beyond the present limits of the hood of the car, and thus it is not necessary F. FREDE, citizens of the to re-build the hood and all benefits of strong, deep end posts are obtained.

' Our improved construction permits the retention of the old wooden end sills of the car body, and it is only necessary to notch these wooden end sills at two points and therefore said end sills retain practically their full strength whencombined with our improved underframe and buffer beam.

To the above purposes our invention con-4 sists in certain novel features of construction and arrangement of parts hereinafter more fully described and claimed.

As shown in the drawings the double body bolster of our improved underframe comprises a pair of bolster members 1 united at their. centers by a longitudinally extending member 2 and the ends of said bolster member 1 are connected by side rails or members 3 which are parallel with the center member 2. The platform frame or extension comprises a center member 4 which is formed y integral with the double body bolster in alinement with the member 2, and formed integral 4with the ends of the member 1 to whichthe member 4 is connected are side rails or pieces 5 which are practically continua-tions vof. the side rails 3. Formed in the forward portion of the member 4 is a series ofpockets 6 adapted to receive the bufling gear. The forward ends of the parts 4 and 5 are united by a horizontally disposed plate orend sill 7, and formed integral with this end sill and occupying a position above the plane occupied by the top of said end sill is a buffer beam 8 which is preferably of the usual box shape, and provided in its front and rear walls with suitable openings 9 for the buffer stems. Vertically disposed, horizontally extending webs or flanges 10 areformed integral with the under sides of the buffer beam 8, end sill 7, platform frame and double body bolster. The body of the buffer beam 8 is extended rearwardlyl over the top' of the end sill 7 as designated by 11 at points equi-distant -from the center of said beam and these rearward extensions are made for the purpose of accommodating extra wide I-beams 12 which are utilized as end posts between the buffer beam and the end' of the hood of the car body. Formed through the top platel of the buffer beam betweenthe front wall thereof and the rear walls of the extensions 11 are'openings 13 adapted to receive the lower ends of the I- beams 12, and formed through the bottom plate of the buffer beam immediately below the openings 13 are T-'shaped openings 14 adapted to receive the extreme lower ends of the end posts 12. The lower front :corners of the posts 12 are notched or cut away so that the front lianges of said posts rest directly upon the bottom plate of the buffer beam while the rear anges and rea-r portions of the webs of said posts project through the openings 14.'A Vertically disposedwalls 15 are formed integral with thev top and bottom plates of the buffer beam immediately adjacent the sides of the openings 13 and 14, thereby materially strengthening the bui'er beam at the points in which the openings are formed, and formed on the under side of the buffer beam in alinementf` of said posts unite with the hood of the car at the proper points. The wooden end sill of the car body rests directly on top of the end sill 7 immediately to the rear of the buffer beam, and it is only necessary to notch this wooden end sill at two points ,to accommodate the rearward extensions 11,- and thus the full strength/of the wooden end sill is practically retained throughout its length.

' The side bearing members used in connection with our improved underframe consist of cast metal beams or rails 17, the ends of whlch are provided with integral horizontally disposed plates or lianges 18 which are perforated in order to receive rivets or like fastening devices by means of which said side bearings are attached to the bolster members 1. A car underframe of our improved construction is very strong and rigid, is comparatively light in weight, combines in one casting the double body bolster, the platform frame, end sill and buier beam and said underframe is particularly adapted for" use in connection with car bodies now -in use, and when applied to said car bodies 'materially strengthens the end portions thereof and the end posts which are rigidly'tixed' to the buffer beam are located so as to conform with the end sills and hoodsof car bodies of the presentconstruction.

It will be readily understood that minor changes in, the size, form and construction of the various parts of our'improved' underfime can be made and substituted for those' herein shown and described without departing from the' spirit of 'our invention, the

scope of which is set forth in the appendedl i claims.
