Specification of Letters Patent.

' To a/ZZ whom t may concern:

Be it known that I, SPENCER OTIs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Car Trucks, of which the following is a s ecification.

My'invention re ates to railway-car trucks,

and has for its object to provide an improved column, spring-plate, and tie-bars therefor, as hereinafter more particularly described.

In the accompanying drawings, Figure l is a side elevation of a car-truck embodying my invention. Fig. 2 is a sectional view on the line 2 of Fig. 3. Fig. 3 is a transverse section on the line?) of Fig. 1. Fig. 4 is an end sectional elevation on the'line 4 of Fig. l. Fig. 5 is a plan view of the blank from which the spring-plate is formed.

Referring to the drawings, a, t, and c indicate the usual upper and lower arch-bars and the side tie-bar of a railway-truck. d represents the columns therefor. As shown, these columns are formed of wrought-metal channeled bars having flanges CZ', substantially parallel with the web thereof. e represents an angle tie-bar riveted to the flanges d. of columns on opposite sides of the truck, forming a transverse tie-bar for the upper ends of opposite columns. Within the ends of the channeled bar is an angle-brace member f, as

shown in Fig.4 2, the horizontal flange of- Which forms a closure for the upper end of the channeled bar and bears against the upper end of the channeled column-bar, the vertical flange of the brace member being secured to the vertica'lflange of the tie-bar by suitable fastening means, as by rivets f As will be readily understood, the strain in the upper arch-bar is a compression strain which is taken up partly by the bolts g. A part of this strain is transferred through the anglebrace member to the column d by means of the bearing of the horizontal flanges of the brace against the column. The bolts g pass through the upper arch-bar, the angle tiehar, the angle-brace member, the springplate h, the lower arch-bar, and the lower tie-bar, as clearly shown in Fig. 2. The co1- umns d rest upon these spring-plates 7L, each of which is formed from a substantially rectangular Wrought-metal plate having flanges LW on its opposite sides. The flangestherefore are on all four sides of the spring-plates. The flanges d of the columns are secured to the flanges 7b2 of the spring-plate by sui table fastening means, as by rivets h5, and the plates are further provided with spring-retaining projections Li. Secured also to the outer sides of the flanges h2 are flat transverse tie-bars h3, connectingI the spring-plates on o posite sides of the truck. The springp ate is formed from a blank, as shown in Fig. 5, having the corners cut away, as indicated in this figure, the flanges being turned up along the dotted lines.

It will be seen that I have provided an eX- tremely simple and strong truck which is firmly braced in all directions and which can be made for the most part of metallic shapes, which can be purchased in the open market without the necessity of employing special patterns therefor. The angle-brace member gives an additional bearing for the bolt and serves to transfer a part of the compression strain on the upper end of the bolt to the columns, as above described.

It Will be understood that I desire to include in the claims such variations from the structure shown and described as may properly fall within the spirit and scope of my invention.

I claim- 1. In a railway-car truck, a column comprising a wrought-metal channeled bar having flanges substantially parallel to its web and substantially parallel members connecting the flanges and web.

2. In a railway-car truck, having columns on each side comprising channeled bars having flanges substantially parallelt to their webs and substantiallyparallelmembers connecting the flanges and web, and tie-bars secured to the flanges connecting the opposite sides of the truck.

3. In a railway-car truck, a substantially rectangular wrought-metal spring-plate having flanges on its four sides.

4. In a railway-car truck, the combination of asubstantiallyrectangular metallic springplate having flanges on its four sides of flanged metal columns secured through their flanges to the spring-plate flanges on opposite sides ofsaid plates.
