UNDERFRAME FOR RAILWAY-CARS.

Specification of Letters Patent. Patenttl Sept. 13, 1910.

Application filed February 26, 1909. Serial No. 480,177;

To all whom it may concern:

Be it known that I, CHARLES S. SHALLEN- BERGER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Underframes for Railway-Cars,.of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, inwhich Figure 1 is a perspective view of a part of an underframe constructed in accordance with my invention. Fig. 2 is a side 'eleva-' tional view of oue'end of said underframe, partly in section. Fig. 3 is a sectional view on line 3- 3, Fig. 2. Fig. -l isa detailed view of one of the bolster sections. Fig. 5 is a sectional view on line 5-5, Fig. 2. lug.

' (i is a side elevational view illustrating one end of a modified form of underframe. Figs. 7 and 8 are detailed views of modified forms of bolster members.

This lnvention relates to a new and useful improvement in underframes for railway I 4ov cars, the object being to construct an underframe wherein the center sill is preferably in the form of a single member, trussed, if desired, the ends of said center sill being connected to castings constitutin r the draft sills of the car, the outer ends 0 said .draft sills being-connected by a memberwhich serves the function of a portion of the end sill, or the deadwood.

In the drawings, 1 indicates the center sill which is preferably constructed of a single rolled member of modified I shape, though an ordinary I-beam, or a built up center sill, may be used'if desired.

2 indicate draft sills having shoulders 3 in the side walls thereof for the abutment of spring fdllowers, said draft sills being cast together and being appropriately flanged and reinforced by webs and gussets. At the rear or inner ends of these draft sills is a thrust-block 4 against which the end of the center sill abuts. This thrust-block is appropriately strengthened by webs formed integral with the casting.

5 IS a rearwardly extending top flange integral with the castin andv riveted by means of rivets 6 to the top ange of the center sill.

This flange 5 is preferably a continuation of the top flange of-th'e draft sills.

7 is a bottom plate, which is practically acontinuation of the bottom flange of the draft sills, said bottom late being secured to the bottom flanges 0 the center sill bymeans of the rivets 8. This bottom plate 7 extends rearwardly beyond the bolster so as to support the center-bearing plate 9, which may be riveted thereto or cast integral therewith. The inner end of plate 7 is secured to the bottom flange of the center sill by rivets 10.

The outer ends of the draft sills 2 are connected together by a member 11 formed integral with the draft sills, said member 11 and the front wall 12 of the draft sills forming a deadwood, the recess in said front wall accommodating the draw bar.

13 is a bracket casting which is preferably made separate and riveted to the member 11, said -bracket casting constituting an upward projection of the deadwood against which the end sill of the car abuts.

14 indicate members of the bolster, which members are preferably castings essentially I-shaped in cross section and whose inner ends are seated in the center-sill. A tension plate 15 riveted to the center sill and to said bolster members constitutes a top cover plate. The king-pin passes up through an opening in the center plate, the web and bottom flange of the center sill being cut away to receive said pin, the bolster members being also recessed as at 14 to accommodate said pin. A cotter-pin or key may be passed through the opening 14" to hold the kingpin in position.

16 indicate flying transoms which are preferably in-the form of castings substantially like the bolster castings, except, of course, it is unnecessary to provide these flying transoins with the side bearin s. A tension cover plate 17 is riveted to tie top flanges of the center sill and to these flying transoms.

18 indicates a casting riveted to the under side of the centersill and preferably in the plane of the flying transoms. This casting has marginal lips extending up oneach sideof the-bottom flange of the 'center sill, as shown in Fig. 5, said lips being located between the center sill and abutting shoulder on the flying transoms.

laterally. The securing rivets hold it against longitudinal displacement. Casting 18 constitutes a double strut or divided queen post in which truss rods 19 are seated. The ends of these-truss rods.pass through openings in the webs of the bolster members and are secured to lugs 2 extending laterally from the inner ends of the draft members. Nuts are provided to adjust the tension of these truss rods.

In Fig. 6 Ihave shown a modified form of truss rod arrangement in which the rods pass up over a block arranged on the cover plate 15, thus givinga greater depth to the truss.

My improved 'underframing as above described is primarily intended for use as a supplemental framing, the center sill being in the horizontal planeof the draft sills and directly transmitting bufling and pulling stresses. Thus, my improvement may be employed as a supplementary underframing for wooden cars provided with the usual longitudinal wooden sills and wooden end sill. It is obvious, however, that my improve ment is capable of use in steel car construc tion in which event, the side sills can be connected to the ends of the bolster and flying transom members, orthe sides of the car, acting as plate girders, can be relied upon to carry part of the load.

Where it is necessary or desirable, in conneetion with cars having wooden sills, to accommodate said sills, I may construct the bolster and flying transom members as shown in Figs. 7 and 8, wherein the castings '20 extend above the center sill, forming a pocket for the receptionof-the wooden center sill 21, the upper portion being either tapered, as shown in Fig. 7 to accommodate the intermediate sill, or formed with an abrupt shoulder, as shown in Fig.8, against which the intermediate sill 22 rests. In the constructions shown in Figs. 7 and 8, a top cover plate 23 is employed which is riveted to the tapered or shouldered portions of the casting, asthe case may be.

I am aware that minor changes in the construction, arrangement and combination of the several parts of my device can be made and substituted for those herein shown and described, without in the least departing from the nature and principle of' my invention.

Having thus described my invention, what I claim is:

1. In, a car underframe, the combination with a center sill, of castings fixed tothe ends of'said-sill, which castin' s each comprise top and bottom plates, raft sills integral with the outer ends of said to and bottom plates and an end plate integral with the outer ends of the sills. e
