Application filed April 9, 1906. Serial 110,310,583.

To all'whoqh it may concern:

Be, it known that I, FRANK S. 'INooLDsBY,

a citizenof the United States, residing at St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Cars, of which the following is a full, clear, and exact description, reference being had'to the accompanying drawings.

This invention relates to a car of composite :construction,the, object being to so employ wood and metal that the advantages of strength, lightness and cheapness will be attained.

"The invention is well adapted for dump cars of the Ingoldsby type, wherein there is a central longitudinal beam to which are hinged dumping doors which form a portion of the floor of the car and drop downward at their outer edges to'dL Qharge the load. When the present invention is em-.

bodied in such dump car, the central longitudinal beam is asteel structure, preferably of the box girder type, while the sides and inclined ends ofthe car are made of planking with suitable metal trussing and bracing.

Other features of invention increasing the efliciency of the car, will appear from the following description, wherein the embodiment of the invention shown by the drawings is fully explained.

In the drawings, Figure 1 is vation of my car. Fig. 2 is a vertical section of half of the car shown in Fig. 1. Fig. 3 is a cross section of the car. Fig. 4 is a portion of an end view, being sectioned through the side sill beyond the bolster.

Fig. '5 is an enlarged, view of the locking lever and its support. Fig. '6 is a face view of the lever-support, being sectioned through the journal boss. Fig. 7 is an edge view of the filler casting which supports the door hinge and the raising shaftl Fig. 8 is a side elevation and Fig. 9 a plan of the hingeeye carried by the filler casting.

The side of the car, indicated by A, is a Howe truss "composed of the upper chord a,

and the lower chord a, which-are channel beams, the main struts a and additional inclined struts, as a and the vertical ties a. The struts and ties are riveted at their lower ends directly to the lower chord-a and at their upper ends directly to the upper chord 0.. These struts and ties are preferably angle members, as shown; Secured to the a side ele- By making the car side in the form of a Howe truss, the effective length of the upper chord is reduced to the distance between the upper end of the two diagonal main. I

struts a ,,whereby the strains are much better resisted. To keep a tight joint between the lower channel beam a, and the planking of the side in case the planking shrinks, I provide a comparatively narrow strip a of seasoned wood immediately adjacent to the channel. The strip being well seasoned and small has comparatively no shrinkage. The strut ties hold it in engagement. with the channel beam a. and the shrinkage of the rest of the planks between themselves or from the strip a does no harin by reason of t e lap on the planks. The inner face of th strip a is beveled to the edge of the channel beam and this channel beam is filled with a wooden strip a, extending between the .end floors of the car to prevent any ledges on which the material might lodge.

When the invention is embodied in a dump car, as shown, there are inclined end floors B, composed of ship-lap, or tongue and groove boards, and a central longitudinal steel ridge beam C extending fromend floor to end floor and having some ofits members passing through the end floors to the I bolsters. As shown, the inclined end floor is secured at its upper end to an upper cross beam B of the car and is braced intermediately by a cross beam Z) which maybe of wood, and by the cross beam angle irons b l and 11 The central bea'l'n may be of the box girder type, composed of a painof vertlcal plates 0 which extend in ,pa'rellelism from the bolster? 'D at one .endof the earl totlie bolster at the other. The upper edges ofthese platesar'e cut off diagonally as they approach thebolster, as shown in 'Fig. 2. The central beam has cover plates cfc extending from'end floor to end fioorand riveted to the upper bent portion of the boX girder plates, and this construction is joined together and re inforced by an angle beam 0 These plates are flanged on the under side of the end floors and thus form connections and supports for the latter, which are secured to them by bolts. Intermediate of the end floors, the upper edges of the plates 0 are bent toward the apex of the ridge and lie along such ridge, being riveted to it and reinforcing it as shown. The plates a carry along their lower edges angles 0 Secured to these angles are cross braces c Stiifener plates 0 are located at intervals in the upper portion of the box girder and have flanges bearing against the plates 0, and rivets pass through these flanges, whereby the stiffener is held in place.

The arrangement of the center sills, draft sills and bolster is covered in my application No. 312,535, filed Apr. 19, 1906. Briefly it comprises a through bolster D having cross webs d to which the ends of the plates 0 and the draft plates E are riveted. Along the upper edges of the draft plates, are riveted angle members 6 and 6 with their flanges facing in opposite directions. These members extend across the top of the bolster and are riveted to opposite sides of the center sill plates 0. A third angle member 0 is provided on the opposite side of the plate 0, from the angle member 6. The angles 0 at the lower edge of the center sill plates extend to the bolster, and additional angles 6 are secured to the draft plates and cross through the bolster and are secured to the lower ends of the center sill plates on the opposite side from the angles 0 This makes a very stiff and strong construction, and one which, in the event of damage to the end of the car, is easily and economically removed and replaced without disturbing the balance of the car.

On the outer sides of the plates 0 and beneath the ridge plates are filler castings 0 secured to both the plates 0 and the cover plates and serving to brace the beam. These castings are of the form shown in side View in Fig. 3 and edge view in Fig. 7. They. have webs e and flanges c by which they are riveted to the cover plates, and flanges 0" riveted to the plates 0. The filler castings also have cross flanges a. To the under side of these cross flanges are bolted the hinge straps F. These straps are provided with eyes 7 to receive the hinge pintles.

The dumping doors are indicated by G. They comprise suit-able planking and floor beams g,the floor beams terminating at their inner ends in eyes which are hinged to the straps F. When the doors are closed, the outermost plank Gr thereon abuts against the lower face of the channel beam a. The doors are adapted to be held in this position by locking levers H pivoted to the channel beam and having hooked lower ends adapted to extend beneath the projecting floor beams g, which preferably have hooks on their outer ends. The upper ends of the levers H may be connected by a link H and operated by a lever H The lever H is journaled on a boss 2' formed on the outer side of a block I which is secured to the channel (z t A boss 71 formed on the inner side of the block seats in a hole in the channel and a rivet 2' seated in the recess in the block holds the same against the channel. A bolt 2' and nut hold the lever in place on its boss. This construction carries the strain from the lever directly to the channel beam itself.

It will be seen that there is some distance between. the lower edge of the chord a. and the floor beams g, and the tendency of the car side to bend outwardly might thus give a severe bending strain to the locking levers which engage the hooked ends of the floor beams. To prevent this, I extend the plate I downward below the channel beam and extend it inward beneath such beam, as shown at i ,Fig. 5. This puts the locking levers in shear and enables them to hold the car side against outward bulging.

When the levers release the doors, they drop by gravity. 1 provide suitable bumpers K to receive the impact of the dropping d0ors,-these bumpers being adapted to engage springs 9 carried on the under side of the doors. The bumpers may be carried on plates 0 secured (preferably by bolting) to the angles 0 on the under side of the box girder, said plates having proper angles a riveted to their upper edges for this purpose. The bumpers, as shown, are pivoted to such plate and may be turned down to hold the door in position to shed outside the rail, or may be turned up, as shown in dotted lines in the left hand portion of Fig. 3, to allow the doors to drop vertical. livoted bumpers are shown and claimed in a co-pending application of mine.

To raise the doors after they have dropped, I provide a pair of rock shafts L on which are mounted arms Z adapted to engage beneath the doors. These rock shafts are journaled in plates 0, riveted to the web 0 of the filler castings 0*. Suitable means, not shown, are provided for rocking the shafts L to cause the arms Z to raise the doors.

The channel beam a which constitutes the main portion of the lower chord, extends from out to out of the bolsters and rests on the upper face of the bolsters to which it is secured. The channel beams at extending beyond the bolsters and terminating at the end of the car are secured to the channels a and to the ends of the bolster. The end sills N are secured to these extension channels a". The projecting flanges t of the main struts a and the end ties a 'for the car, .end floor to 'the bolster and secured are removed where the channel a crosses them and filling plates are provided between these channels and the,car sides, so that the channels may be conveniently secured in place outside of the struts extensions of the side are placed as described so that in case of any damage to the end of the car, the extension channel may be easily and economically removed and replaced without disturbing any of the balance of the car.
