Specification f Letters Patent.

Patented Feb. 7, 1911.

Application filed January 14, 1908 Serial No. 410,791.,

To all whom it may concern:

Be it known that I, Ax'rox Bncnnn, of Columbus. in the county of Franklin and State of Ohio, have invented certain new and useful improvements in "Uuderframes;

for Cars; and I do hereby deciL r e the. following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it. apperprovide an underframc for vehicles of the character above specified, which shall be simple and substantial in construction and which shall comprise few parts supported upon the pedestals through the medium of angle-beams. beyond which latter the transverse members of the structure are made to project.

With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings. Figure 1 is a transverse sectional view of a car undcrframe embodying my improvements. and Fig. 2 is a partial longitudinal sectional view.

l, 1 represent angle-beams, which in the present instance are shown as Z-beams, and these are mounted upon and secured to the pedestals 2 in which the journal-boxes for the axles are disposed.

3 represents a center girder which may comprise two channel. plumbers 4, 4. To the outer face of eacli., -'1'Lmber of the center girder. the inner end of one-member of a transverse beam 5 is secured. Each member of the transverse beam may consist of a rolled 0r pressed channel-iron and secured to a center member girder by means of an angle-iron or gusset plate 6,-or if.desired the inner end of each cross-beam member may be'provided with a flange secured to the cen efgirder. In either case a filler 7 is disposed between the members at the center girder. The cross-beam members project beyond the. Z-beams 1, 1, rest upon them and are rigidly secured to said Z-bcams by means of suitable bolts or rivets. It will be observed that the bottom of the center girder is in a plane above the supports of the Z-beams on the pedestals, and that therefore said center girder is supported or suspended from said Z-beams through the medium of the cross-beams 5. A tension plate or strap 8 extends across the center girder and is securely riveted at respective sides thereof to tl1e fianges of the cross-beam members. A bottom compression plate 9 passes through slots made for its accommodation in the center girder members and said bottom compression plate is secured by rivets to the lower flanges of the cross-beam anembers.

Angle-irons 10am secured upon the crossbeams 5 near the outer ends of the latterand extend along the sides of the structure. Similar angle-irons 11 are located at the ends of the frame-work and atthe corners of the latter the angle- irons 10 and 11 are secured together by suitable gussets. The base flanges of these angle-irons may project inwardly or outwardly as desired and against the vertical portions of the angleirons 10, the side-sills 12 (which are supported upon the ends of the cross-beams) abut. and may if desired be secured thereto. In a similar manner the end-sills 13 abut against the angle-irons 11 at the ends of the framework.

Furring strips 14 are located upon the cross beams 5 and extend longitudinally of the structure for supporting the car-floor: ing. The ends of the center girder members are provided with seats for end sills and the forward portions of the center girder'members sustain the car platform.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

1. The combination with a center girder and car pedestals. of longitudinal side beams, each having an upper tension-member and a lower compression nn...ber, the lower compression members of tit: side beams resting directly: upon the car pedestals, and crossbeams resting directly a on the upper tension members of the site beams and connected with the center girder.

2. The combination irith side Z-beams and a center girder, of a cross-bearer fixed to 2 w i Y 983,263

the center girder and sup rting the same, said cross-bearer resting irect-ly upon the side Z-beams and projecting laterally beyond the same.

3. The combination with car pedesta'ls and a center girder, of side Z-beams resting directly upon and secured to said pedestals, and cross-bearers resting directly upon the side Z-beams and projecting laterally beyond the same, said cross-bearers being secured to the center girder and constituting the supporting means for the latter.

4. The combination with car pedestals, of side Z-beanis located upon said pedestals and having their lower horizontal flanges and their vertical webs secured to said estals, cross-bearers secured upon sai Z- heams, and a center girder supported by said cross-bearers.

5. In a car structure, the combination of Z beams supported upon the pedestals of the car structure, a center girder andcrossbeams, each -comprising two members, one member of each cross-beam secured at its inner end to the center girderand supported at its outer end by a Z-beam.

6. In a car underframe, the combination with side angle-members adapted to be supported upon the )edest-als oi a car structure, and a center gir er, of cross-beani members comprising channels secured at their inner ends to the center girder and projecting lab erally beyond the side-angle-memhers and secured to tile latter, and plates or straps secured to the flanges of said channeled crossbeam members and extending past the center girder.

In testimony whereof, I have signed this specification in the presence of two sub scribing witnesses. 7
