To @ZZ whom, it 11m/y concern,.-

Beit known that l, HERBERT R. KEITHLEY, a citizen of the United States, residing at Chicago, .in the county of Cook, in the State of Illinois, have invented new and useful Improvements in Freight-Gars, of which the following is a specification. This invention relates to a metal railway freightcar which is built `up of ordinary rolled shapes and plates, and more particularly to a combined gondola and hopper-bottom car.V

The object of the invention is to produce a light strong car of simple construction and composed of the minimum number of parts and weight of metal consistent with great rigidity and carrying strength.

The improvements are directed to certain features of construction whichy will appear from the following description and claims.

In the accompanying drawings, consisting of four sheets, Figure 1 is a side elevation of one-halt` of a combined gondola and hopperbottom car embodying the invention. Fig. 2 is a longitudinal vertical section of one-half of the car in line 2 2, Fig. 4. Fig. 3 is abottom plan view of one-half thereof. Fig. 4 is a transverse vertical section thereof in line 4 Li, Fig. l. Fig. 5 is a transverse vertical section thereof in line 5 5, Fig. lv. Fig. 6 is a transverse vertical section thereof in line 6 6, Fig. l. Fig. 7 isa fragmentary ver tical central longitudinal section thereof in line 7 7, Fig. 3. Fig. 8 is a fragmentary transverse section showing one of the holsters.

- Like letters of reference refer to like parts in the several gures.

Brieiiy stated, the car is composed of vertical sides in the form of built-up plate-girders which aresupported by body-holsters arranged in the vusual relation and serve .as the lmain carrying elements or members of the car,vertical ends which connect the sides, longitudinal center Asills arranged in their usual relation at-the center of the car, transverse transoms, and floor-beams arranged between the bolsters, and a bottom which connects the sides and ends of the car is composed of horizontal bottom or floor plates and hoppers arranged on opposite sides of the center sills between the holsters and transoms. Each plate-girder side is composed of vertical end web-plates A, acenter web-plate A', a top or compression chord or member B', and a lower or tension chord or member C. The center Web-plate is arranged in vertical plane outside of the plane of the end web;

plates, with its ends overlapping and rivetedl c represents a filler-plate inserted between the vertical (lange of the upper chord and the center webfplate. Each side is provided with two substantially triangular vertical plates D, the upper edges of which are arranged between the center Web-plate and the lower chord to which `they are connected by the rivets connecting'the lower chord with the web-plate.

D represents a vertical 'plate which eX- tends from one triangular plate to the other,

`with'its upper edge arranged between the center web-plate and lower chord, to which it is connected by the rivets connecting the chord and web-plate together. The plates D and D,which extend below the lower chord, constitute, respectively, the outer side Walls of the hoppers and the supports for the ends of the transverse transoms.

d represents vertical stieners riveted to the web-plate and vertical plates D D' of the plate-girder sides.

Each of the end walls of the car preferably comprises a vertical plate E, connected to the ends of the plate-girder sides by vertical corner-posts e or in any other suitable manner, and an upper angle-bar e', arranged simi- .larly to the upper chords of the plate-girder sides. g

F represents the longitudinal center or draft sills, which are located in their usual relation at the center of the car 'below the channel-beams arranged with their Webs ver the center sills to the sides of the car.

tical and their flanges projecting horizontally outward. i

The body-bolsters, which are arranged in their usual relation near the ends of the car, are preferably constructed as shown inFigs. l, 2, and 8. Each bolster comprises a pair 'of separated vertical membersfat each side of the center sills, secured in any suitable manner at their inner ends to the center sills and projecting outwardly therefrom beneath the horizontal flanges of the lower chords of the plate-girder sides to support the latter. The lower edges ot' the vertical members of the bolsters are connected by a continuous cover-platef, which extends from one end to the other of the bolster beneath the center sills. The bolster construction thus far described isset forth more in detail in my United States Letters Patent No. 725,849, dated April 2l, 1903. The upper chord of the bolster is formed by the horizontal fioor-plates of the car, as hereinafter described. Transverse transoms are arranged betweenthe body-bolsters. Each transom is preferably in the form of a built-up plate-girder constructed as follows, (see Figs. 2 and 5:)

G represents vertical web-plates, which extend from the center sills to the vertical depending plates D of the plate-girder sides, to which and the center sills the web-plates are connected by angle-plates or in any other preferred manner.

- g represents angles extending from the center sills to the side plates D and having their vertical anges riveted to the upper edges of the web-plates of the transom.

g' is a plate extending from end to end of the transom over the center sills and riveted to the horizontal flanges of the angles g. This plate forms a continuous or unbroken upper chord for the transom.

g2 g3 represent, respectively, a flanged bar, preferably an angle-bar, and a plate which extendst'rom end to end of the transom beneath the center sills, the angle-bar having its vertical iange riveted to the vertical webplates of the transom and the plate g3 beingv riveted to the horizontal flange of the angle g2. This angle and plate form a continuous lower chord for the transom. g4 represents a short vertical channel-plate arranged between t'he center sills and having its vertical flanges riveted to the center sills and its lower end riveted to the angle g2 of the lower chord of the transom.

H represents floor-beams, which are arranged betweenthe body-holsters and transoms nearer to the holsters and extend from The floor-beams are preferably formed of Z-bars and are connected at their inner ends to the center sills by angle-plates or in any other suitable manner. l. The outer ends of the door-beams are secured in any suitable manner to the depending lower ends of Vertical angle-bars h, which constitute stiffeners for theplate-girder sides. The bottom or iioor at each end of the car is formed by horizontal end and intermediate door-plates I and J. The end plate I is secured at its outer endto the adjacent'end of the car by an angle-bar t' or in any other suitable manner and extends over the vertical members of the bolster. The intermediate floor-plate J extends from over the bolster to a point over the adjacent floor-beam H. The meeting ends of the tioorplates overlap over the bolster, as clearly shown in Fig. 2, and are riveted together and tothe upper flanges of thevertical members of the bolster, the plates thus forming an upper or tension chord for the bolster of double thickness and which extends continuously or unbroken from end to end of the bolster. The side edges of the floor-plates I and J eX- tend beneath and are riveted to the longitunal tension-flanges of the plate-girder sides, suitable tlller-platesjbeing inserted between the said flanges and the plate I. Both of the floor-plates l and J are riveted to the upper flanges of the center sills. The central horizontal portion of the bottom or floor is formed by a plate K, which extends from one transom to the other and overlies and is riveted to the upper flanges of the transoms. The side edges of the plate underlie and are riveted to the-horizontal tension-iianges of the plate-girder sides.

' L represents a horizontal cover or connecting plate for the center sills. It rests on and is riveted to the top flanges ofthe center sills, extending from bolster to bolster and projecting laterally beyond or overhanging the iiang'es of the center sills. This cover-plate is located beneath the central and intermediate floor-plates J and K.

The hoppers or hopper portions of the bottom, of which there are four, are arranged between the transolns and ioor-beams H on opposite sides of the center sills. The outer side wall of each hopper is formed by one of the depending triangular plates D of the sides, and the inner side wall is formed by a correspondingly-shaped plate M, arranged verti! cally beside the adjacent center sill. vThe plate M is connected at its upper edge to the overhanging portion of the cover-plate L for the center sills by an angle m or otherwise. The inclined bottom of the hopper is formed by a plate m', secured at its side edges to the side walls D and M of the hopper. The upper transverse edge of the inclined hopperplate m extends between and is riveted. to the adjacent floor-beam and end of the intermediate iioor-plate J. The other transverse wall of the hopper is formed by a door N and the inclined plate n, to which the door is hinged. The hinge-plate n Ais vconnected at its side edges to the side walls of the hopper,

and its upper edge extends between and is riveted to the angle and plate forming the upper chord of the adjacent transom. The hopper-door swings downwardly toward the center of the car in opening.

The end sills of the car are preferably con- IOS IIO

structed as shown in Figs. 2 and 3. end sill consists of a Z-bar O, arranged with its web horizontal, its outer Iiange projecting downwardly and its inner flange projecting upwardly beside the lower portion of the end wall-plate of the car, to which said ange is riveted. The end portions of the horizontal flanges of the angles forming the tensionchords. of the plategirder sides project ontwardly beyond the end wall-plates of the car beneath the web ofthe end sill, to which they are riveted or bolted, thus rigidly connecting the ends of the end sill with the ends of the tension-chords of the plate-girder sides.

The door-operating mechanism is preferably constructed as follows: The two doors for the adjacent hoppers on opposite sides of the center sills are connected by a common flanged bar P, preferably a channel-bar riveted to the lower free'ends ofthe doors. This connecting-bar is connected centrally by a linkp to a crank p, located between the center sills and secured to a transverse rockshaft p2, which is journaled in suitable-bearings p3, secured to the center sills and the inclined bottom plate of one o-f the hoppers. The shaft is provided at its outer end with a rock-arm ,294. Q represents a door-operating lever which is pivoted on a stud or pin q, secured to the side plate D adjacent to the rockarm p4. The lever is provided with a cam plate or portion q', the circular face of which in the position of the lever shown by full lines in Fig. l engages the rock-arm p4 to hold the latter and the rock-shaft stationary with the doors closed. To open the doors, the lever q is swung upwardly, as shown by dotted lines in Fig. 1, which releases the rock-arm p4 and permit-s the doors to swing open. In theopen position of the doors the rock-arm engages the inclined face of the cam, and when the lever is swung downwardly the rock-arm and the rock-shaft are returnedto the full-line position shown in Fig. l, thereby closing the doors and locking the same. The lever Q thus affords a convenient and desirable operating means as well as the locking device for the doors.
