` Application tiled J une 1,1891. Serial No. 394,734. (No model.)

To all whom it may concern,.-

Be it known that I, JACOB J. SoUDER, a citizen of the United States, residing inthe city ofVashington, in the District of Columbia, have invented a new and useful Dumping- Car, of which the following is a description.

The invention relates particularly to certain improvements in the dumping-car shown in a former construction by me, which constitutes the subject of United States Patent No. 371,224, which was issued to me October 11, 1887.

The present car, like that above referred to, -is constructed with a view to thev convenient transportation simultaneously of granular material in bulk in a lower compartment and of miscellaneous merchandise in packages in an upper compartment.

The invention consists'in certain improve-y ments in the construction of the bed-frame and its immediate connections, whereby the supports of the same are strengthened and whereby additional 'and more readily available space is afforded for discharging the granular contents of the car; in certain modiiications in the construction of the hopper and its bottom connections, whereby the' longitudinal hinge rod or bar of the dischargingchutes or drop-doors is supported directly by the transverse supporting-bars of the hopper; in certain improvements in the drop-doors, whereby the locking-bars are engaged` directly with the body of such doors and with the lugs upon the transverse supporting-bars 5 in the provision of auxiliary lugs and supports upon the exterior sills of the bed-frame and of locking-bars which engage with said supports to maintain them in their supporting position; in the provision of hinged inwardly-swinging wings which, when in their outward adjustment, constitute the sides of the discharging-chute; in certain improvements in connection with the pivoted and adjustable hoor-sections, andinl various other novel constructions, all of which will rst be' particularly described, and then distinctly pointed out in the claims.

, In the-drawings,`Figure lis a side elevation of the central or hopper portion of the car, the sliding side door being open and the hinged falling or drop door, which constitutes bottom plan view of a like central portion of the car, the discharging-chute-doors and their 1 lockingvappliances being in rtheir closed and locked'adjustment. Fig. 4 is a perspectiveview, the car being tilted, showing details of the bottomv of the bed-frame, a portion of one of the wings of the drop-door and portions of the bed-frame being broken out and the dropdoor of the discharging-chute being open. Fig. 5 is a transverse vertical section of the lower portion of the car on the line/v o in Figs. 1, 2, and 3, looking in the direction of the feathered arrow. Fig. 6 is a transverse vertical section on the line c e' in Figs. 1, 2, t

and 3, looking in the'direction of the unfeathered arrow. Fig. 7 is a detail of the pivoted floor-section as when looking from outside the car through an orifice in the Wall of the same. j Fig. 8 isa detail, partly in section and vpartly in elevation, ofthe fixed end Hoor-section, the pivoted Hoor-section, and the inclined ybrace-rest, showingthe manner in `which the pivoted iloor-sections'engage under the projecting flange or covering-piece of the fixed floor-section. Fig. 9 is a partial top plan view, the roof of the car being removed and the floor-sections being in their horizontal adjustment. Fig. 10 is a detail, partly in section on the line w w in Fig. 9, showing the connection of the pivoted floor-sections with the central detachable hoor-sections. Fig. 11 is a section on the line .r w in'Fig. 9, showing the relation of the floor covering-plate in the side-door openings to the coincident detachable floor-sections.

As will be seen in the drawings, I provide in the bed-frame B of the car A, between the cross-sills b2 b2 at the ends of the hopper H, the single pair of short longitudinal sills b3 b3, which are arranged near together over the middle of the hopper. This construction affords a large clearing-space b4 between such central sills h3 h3 and the exterior longitudi- IOO nal sills ZJ b', which is essential in discharging coarse mineral or other substances. To compensate for possible loss of strength resulting from this change in construction, halfsills b5 b5 are provided between the central and the exterior longitudinal sills, and underneath and across these half-sills, at the inner extremity thereof, is extended a longitudinal truss-rod 11G, which is secured by its ends to the transverse end sills of the bed-frame or equivalent fixed part of the car. The exterior longitudinal sills b b also are each provided with a longitudinal truss-rod bs, which is similarly secured to the extremities of the bed-frame and which in its central portion bears against the lower ends of the equalizing-braces 117 127, which are suitably secured to and which project downwardly from the under surface of the bed-frame. If desired, the rods h6 may be connected by transverse tie-rods blo.

The hopper II is, as shown, directly supported by the transverse bars 7L, which rest by their ends in the body of the exterior longitudinal sills b. In addition to these supports I provide the stirrups h 7L', which by each end are secured to the short longitudinal sills b3 b3. I provide a hinge-bar h2, which is coterminous with the lowest portion of the hopper, which is secured within thelower and curved portion of the transverse bars 7L and of the stirrups 71, and which receives the looped ends of the hinge straps or cleats his.

Under my construction the body of the drop-doors D has notches d in the ends thereof corresponding to the lugs or catches 7b3 upon the transverse supporting-bars h, and when such doors are raised to their closed position the pivoted supporting-arms E, having at their pivoted end an outward curve, as seen in Figs. l and 8, engage both the lugs h3 upon the supporting-bars 7i and the main portion of the body of the door D itself. In addition to these supports at the ends of the drop-doors I provide upon the outer edge of such doors projecting lugs CZ', and upon the bottom surface of the bed-frame of the ear I attach holding lugs or latches a, which are movable in a horizontal plane upon their pivot a. In connection with these swiveled holding-lugs d I provide upon the bed-frame the downwardlyextending catches a2, each having a notch. (Not shown in the drawings.) Then the drop-doors D are lifted to their closed position, an outward movement of the locking end a4 of the lug a brings such end into engagement with the lower face of the projecting lugs d and with the notch (not shown) in the catch a2. By the same movement the pin a5 upon the opposite end of the holdinglug a is caused to project directly outward at a right angle with the side of the car, and in this position it is engaged, when the door is locked, within a perforation e in the lockin g-bar c, which moves in the way or guide a, secured to the bed-frame, and which is connected by a pivot-joint e2 to the pivoted supporting-arm E. Each locking-bar c, in addition to the perforation e for engagement with the pins a5 of the holding-lugs @,is provided near the outer extremity thereotl with a per foi-ation c3, by which, when in its locking position, it is received upon a pin f2 in a downwardly-projecting extension f of the locking appliance F.

As a means for closing the in terval between the body of the hopper and the ends of the drop-doors, when such doors are in their open or discharging adjustment, I pfovide the wings W, each of which is connected by a hinge-joint w to the body of the hopper and is adapted to be swung bodily inwardly, and, when the drop-door is closed, to lie flatly at full length against the upper surface of the same. A iange or stop d2 is provided upon the upper surface of the door, near each end thereof, which in closing the door enters a corresponding shallow groove 7L, which is formed or bounded upon one side by a downturned edge 7u of the body of the hopper and upon its opposite side bythe body of one of the transverse supporting-bars 71, and effccts a tight closure therewith. When the door is dropped, the closing-wing IV is thrown outward against the flange or stop cl2, and is held thereto by rigid adjustment of the door through the operation of the winding-shaftS and its chain s. When the wing andthe door are closed and the locking-bareis in engagement with the pins ai of the pivoted holdinglugs a and with the pins or studs f2 upon the locking appliance F, the hinged covering and securing plate f3 of such locking appliance is closed down upon the pivoted locking-bar e, its perforation f*L receives the loop of the staple f5 upon the extension f and its perforationfG receives the squared end of the winding-shaft S. Primarily the windingshaft is held against backward revolution by engagement of the pawl]7 with the teeth of the ratchet fg, the pawl being in turn secured by the cam f8; but additional security is assured through the provision of the securing plate or hasp f3 and the engagement of the shaft within the perforation f of such plate, the whole, as will be understood, being finally secured by engagement of any suitable padlock in the loop of the staple f5.

I provide at each lower corner of thehinged Hoor-sections g of the Hoor G a hinge-piece g', the outwardly-projecting ear g2 of which has a perforation g to receive a pivot-pin g, by which it is connected to a link-bargf, the opposite extremity of which has a ,slot g. Upon the coincident inner face of the sill b is secured an angular lug b, the perforated flange or ear bm of which receives a pivot-pin gi, which extends through the slot Q6 in the link-bar and moves freely therein. The seetion g is beveled upon its outer edge g from the top downwardly and inwardly, and the coincident portion of the sill b is provided with a rest or bearing-piece bm, which is correspondingly bereled from the top down- ICO wardly and outwardly from the sill. The slot g6 in the link-bar g5 permits free movementv out danger of injury to the hinge connections,

and so that when the section has been lowered to its horizontal position it may engage by its cut-away portion or recess g8 beneath the projecting covering-Hangs Q10 of the fixed floor-sections g9. It will be noted that under this construction the floor-sections g are hinged, not to the fixed sections Q9 of the floor, but to the bed-frame of the car, and that the provision of the beveled support or rest 513 affords a continuous bearing for the section, while avoiding the feature-objectionable in a self-clearing car-of a shelf-like bearing projection.

Although I have shown the transverse sills h2 as extending' across the body of the bedframe and the intermediate longitudinal sills h3 b3 as terminating at such transverse sills and as being continued by a separate short longitudinal sill B5 between transverse sills b2 and the end sills b, it will be apparent that the sills b2 and the sills b3 might be vhalved together and suitably re-enforced, the sills h5l under such construction extending from end to end of the bed-frame, the essential purpose of this part of my invention being accomplished under any construction in which the longitudinal sills b3 are placed near together in the center of the bed-frame and in which the half-sills b5 are so placed in connection therewith as to produce the discharge-open' ings b1. In a similar manner these inner longitudinal sills might extend from end to end extend along and are secured upon the lower surface of the half-sills h5, securing the same together and preventing inward or outward movement of the longitudinal sills of the bedframe.

As seen in Figs. 5, 6, 9, and 11, I provide in the openingfor the side door A ofthe car upon the sill h covering-plate 514, the inner portion of which constitutes a flange b15,which overhangs one of the central detachable floorsections g17 of the oor G and extends into a corresponding recess 912 in the upper surface of such floor-section. At each end the sections Q17 have a similar recess 914 to receive the covering-plate 913 of one of the pivoted floor-sections g. A stop as is pivoted to the lining a7 of the car in such relation to the plate upon the section g that when the covering-plate Q13 of such section is engaged with the recess 914 in the section g17 it will be held Lopening an exterior downturned in such engagement by adjustment of the stop against the covering-plate.

As will be seen in Fig. 9, the two detachable floor-sections g17 are at their meeting edges provided with a recess and a corresponding flange like those shown at the junctions of the floor-sections g9 and g; and g and Q17.

In the drawings the hopper is represented as composed of metal, and for the transportation of mineral substances I prefer to so construct it; but of course I do not restrict myself in thechoice of material'.

Having thus described my invention, I claim- 1. The combination, with the end sills b b, of the intermediate transverse sills B B, the intermediate longitudinal sills b3, the halfsills b5 h5, forming in connection with the intermediate and the exterior longitudinal sills the discharge-openings or clearing-spaces b4, and the longitudinal truss-rods h6, extending across the inner ends of the half-sills h5, substantially as and for thepurpose set forth.
