SPECIFICATION forming part of Letters Patent No. 763,947, dated June 28, 1904.

Application filed January 23,1904,

'o all 'wi/mn t may concern:

Be it known thatI, ANTON BECKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, -have invented a new and useful Metallic Flush-Floor Dump-Car, of which the following is a specification in its best form now known to me, reference being had to the accompanying drawings, in which similar numerals indicate the same parts throughout the several views.

My invention relates to metallic cars capable of being unloaded by the mere opening of a series of doors.

The object of my invention is to provide Asuch a car in which the floor is flush and smooth when the doors are closed and to provide means by which the car is self-cleaning, so thatwhen unloading is attempted all of the yload is automatically removed. l My invention consists in a car capable of accomplishing the above objects which can be easily and economically constructed, which will not readily get out of order, and which can be easilyand cheaply repaired.

It also consists in a novel form of end sill and bolster and means for attaching the draftrigging, adapted to assist in the accomplishment of the general objects of the invention. i

It also consists in novel arrangements of parts and other features, which will hereinafter be more fully described and claimed.

In the drawings, Figure 1 is aside elevation, and Fig. 2 is a plan view, of approximately one-half of a car, showing my invention in` its preferred form. Fig. 3 is a partial end .View of thev car, Vshowing'the end sill and draw-bar attachment. Fig. 4 is a detail sectional plan viewtaken on line 4 of Fig. 3. Fig. 5l isa detaillsectional side view of the end sill, taken online 5 of Fig. 3. Fig. 6 is a sectional view taken kon line .6V of Fig. l, showing one of the several cross-bearers of the car.- Fig. 7 .is a detail view of a portion `'of a cross-bearer,-showing the method of atl tachment of.y wings which protect the edges of the doors of the car in a manner'to be Y hereinafter described. Fig. 8 is a detail end,-

Fig.. 9 is a sectional end view on line 9 of Fig. 1, showing the bolster and the construction for attaching the draft-rigging. Fig. 10 is a sectional view through the crossbearer, taken on line 10 of Fig. 9, showing particularly the wings heretofore mentioned. Fig. 11 is a detail view of the rack applied to the cross-bearers. Fig. 12 is a view from the bolster to the end of the car, taken partly in section on line y12 of Fig. 3 and partly as a side View on li'ne 121L of Fig. 9. Fig. 13 is a partialpdetail plan view taken ony line 13 of Fig. 12. l

In the preferredform of my invention I provide an underframe having extending from end to end of the car, through its center, a central plate 25, the plate being cut away, as shown in Fig. 12, to provide for the king-pin and draw-baryoke, this'cut-away being' indicated by the lines 26, 27, 28, and 29. The

full depth of this plate between the holsters` is, as shown, the full depth of the under-frame. The central plate 25 has on its lower edge a fianged plate 32, running, as shown in Figs. 1 and 12, from a point beyond one bolster to a corresponding point at the other end of the car beyond the other bolster. This web-plate 25 and flanged plate 32 are connected together by angles 33 and 34, running from bolster to bolster, as shown. Connected to this central plate-girder, just described, are a scries of cross bearers, as shown in Fig. 1. These cross-bearers at the holsters are double, with flanges extending in both directions,`and at other 'points the cross-bearers are single, with flanges extending in only one direction. The opposite halves of tthese cross-bearers may be made of pressed steel shapes of the size and form desired, or theyv may be made ofwebbed plates and flanged angles, as desired. For convenience `of illustration Ihave shown halfl of the vcross-bearers as composed of` plate 40, forming the web of one-half of the cross-bearer, the same having pressed flanges 41, 42, and 43. On -the opposite side of the central plate 25, heretofore referred to, is a corresponding plate 46, having corresponding pressed flanges 47 and 48, &c. The two iianges 44 and 47 of these corresponding plates 46 and 40 are shaped as shown in Fig. 6, so that they fit snugly over the central plate 25, the angles 33 and 34, and the iianged plate 32, and are secured to these various parts by rivets 50 51 52 53 54, &c., asshown in Fig. 6. rj he lower flanges 41 and 48 of the crossbearer are for purpose of clearance and convenience in angular form, as shown in Fig. 6. rlhe cross bearer is strengthened by a plate 60, extending from side to side of the car, running crosswise of the underframe of the car, secured to the anges 41 and 46, heretofore described, by rivets 61 and to the fianged'plate 32' and angles 36 and 34 by rivets 50 and 51, heretofore described. Similarly the underframe of the car is strengthened and formed by another reinforcing-plate 65, extending across the top of the under-frame and the top of the cross-bearer flanges and secured to said flanges by rivets 66. (See Fig. 6.)

Secured to the ends of the bolsters and cross-bearers by rivets 68 and also independently secured to the ends of the car are stakes 69, made, as shown, of double angle-irons at the center and bolster and of single irons elsewhere.

Secured to the upper reinforcing-plates, heretofore referred to, are a series of castings 71, 72, and 73. Through these castings, just described, is a rod or shaft 75, on which are journaled or hinged oppositely-disposed wings 76 and 7 7, which in the manner to be hereinafter described operate to make that portion of the car over the cross-bearers selfcleaning. In commercial practice each of these wings is approximately four inches from the center of the rod to the outer edge of the wing. rlhese hinged wings are so made that they extend clear across the top of the cross-bearers of the car, as shown in Fig. 2, but are preferably cut away at the center in angular lines 80 and 81," so that they may operate properly in connection with the dumping-doors, as will be hereinafter described.

At intervals along the top of the centerplate 25, heretofore referred to, are a series of hinge-supports 85. These hinge-supports arc connected by a rod, or preferably by a series of short rods 86, on which are journaled or hinged floor-sections or doors 88, made up, preferably, of large plate, which just lit in between the central plate-girder of the underframeof the car, the cross-bearers, heretofore described, and the side of the car. (See Fig. 2.) These doors are, as shown in Fig. 2, substantially the same size between the bolsters, while the doors 89 at the end of the car outside the holsters are for convenience made slightly larger; but manifestly the car may be so designed that they are of approximately the same size as the other doors. These doors, as shown in Fig. 6, are adapted to be moved to a horizontal position, in which position they form sections of the floor of the car, and are also adapted, as shown in the full lines on the right of said figure and the dotted lines vof the same figure, to be tilted downward,

so that material upon them will slide off. These motions of the doors of the car may be made by hand or by any of several forms of mechanical devices, one of which will be hereinafter fully described. On the edges of the doors 88 adjacent to the cross-bearers are secured plates 90, adapted to fit under the edges y of the wings 76 and 77, mounted on the tops on the opposite plates 46 are cut other correspending parallel slots 96. Running the entire length of the car through these slots and on the opposite sides of the car are two shafts 98 and 99. Mounted upon said shafts are pinions 100, meshing in racks 101, rigidly secured to the under side of the slots and 96, heretofore referred to, from which it will be seen that if the pinions 100 travel up and down the racks 101 the shafts 98 and 99 will be moved from the outer ends of the slots 95 and 96 to the inner ends thereof, and vice versa. Also mounted upon shafts 98 and 99 are guides 93, heretofore referred to, adapted to slide backward and forward in the slots 92, and antifriction-rollers 103, adapted to bear against the under side of the door (see Fig. 10) and move along from the side of the car to the center, and vice versa, from which it will be seen that by moving the shafts 98 and 99'frorn the side of the car to the center the door 88 will through the agency of guide 93 and wheels 103 move the door downward to the dottedline position against the resistance of foreign obstructions and that moving the shaft in the opposite direction will move the door from the dotted-line position shown at the left of Fig. 6 to the full-line position, where the door is again in line with the floor. On the outer end of these shafts 98 and 99 and outside the end sill, as shown in Figs. 2 and 3, are ratchetwheels 105, adapted to be engaged by pawls 106 of the universal levers 107 of the ordinary construction, the operating of these levers being adapted to move the shafts 98 and 99, with the parts heretofore described attached tok them, along the racks 101 from the outer end of the slots 96 and 97 to the inner ends.

As heretofore described, when the floorvare lowered in the manner described -in the last paragraph these wings 76 and 77 descend .from the full-line horizontal position of Fig.

to the dotted angular line position, as shown in Fig. 10, the angular edges 8O and 81 of said wings sliding' along the central portions of the doors. The change to the tilted position causes all dirt and other material which in the loaded car rested upon the tops of the the doors themselves lift these wings'7 6 and 77 from the inclined position shown in Fig. 10 to the full-line position, where the iioor of the car is again level.

The box of the car is formed by riveting to the inside of the stakes 69, heretofore referred to, plates 110 and reinforcing the tops with an angle-iron 111, having one flange projecting over the top of the stakes, as shown in Fig. 9, thereby making a smooth neat edge to the top of the box of the car. The angle-irons at the side and ends of the car are joined by neat plates 112, as shown in Fig. 2. The stakes are reinforced and secured to the under frame of the car by an angle-iron 114, secured by rivets to the stakes and to the bottom of the car, as shown in Fig. 9, the angle-iron 114 and the iiange 43 of the cross-bearer web 40 being supported by castings 115, which serve to give greater strength and rigidity to the connection between the stake and the top of the cross-bearer. The lower flange of this angle 114 extends, as shown in Figs. 9 and 10, over the edge of block 115, so as to make a jam or stop for the doors of the car to bear against when the door is up. Stops 145 are placed on the cross-bearers to limit the downward motion of the door. In order to reinforce the side of the box of the car outside of the holsters, I rivet to the side plates-110 two U-shaped angle-irons 117 and 118, the bottoms of the U-shaped angle-irons being placed back to back and riveted together, as shown in Fig. 1. In order to carry off water from the tops of the angles, a slight clearance should be left betweenthe bottoms of the Us where riveted together. I find that this construction greatly increases the strength and rigidity of the end of the car. In order toprovide means for attaching one of the several forms of draft-rigging, l provide between the bolster and end sill a housing (illustrated in Fig..9)consist ing, preferably, of two channel-irons120, se-

cured `to the bottom iianges of thebolster by suitable rivets and reinforcing-plates and having an inverted-V shape composed of pressed plates 121, secured by rivets 122 to the central Vweb-plate 25 and by rivets 123 to the tops of the channel-irons 120. By making the top of this housing of this inverted- V shape I allow the iioor-doors 88 to swing V down, as heretofore described, and also allow ample roomA for the various parts of the draftrigging.

In order to provide for removing the drawbar while providing strength for the car and in order to have the draw-bar at the proper height while keeping the car low upon the tracks, I have the outer end ofl the channels 120 rolled upward, as shown in Fig. 12, .and secure across their under sides by bolts 140 an angle-iron 126 and secure tothe angle-iron and to the ends of the channels or corresponding members 120 an end plate 127, the same having' an inverted-U-shaped notch cut in it, forming a hole 128 above the angle-iron 126, through which the draw-bar is adapted to pass. In order to further strengthen the end sill, I secure to this plate 127 and to the webs of the end sill a casting 130, (shown in detail in Fig. 3,) having in its center a reinforcingrib 131. This construction gives the end of the car great rigidity, so that there is no danger of the draw-bar or draft-rigging being torn from the car with any ordinary strain.

The inverted-U-shaped cut is, as shownrin Fig. 12, carried into the L-shaped plate134 in vthe end sill, to be more fully described hereinafter.

In order to provide an end silloutside of the underframe of the car correspondingto the dead-wood of an ordinary car, I secure to the. under side of the end of the car channelirons 133,.having their ends .inclosed in L-' shaped sections 134, and secure the whole together by a Z-bar 135, secured to the end of the car and to the channel and tothe L-shaped sections by suitable rivets, as shown in Figs. 4 and 5.` The corner of the end sill iscapped by a push-pole pocket 136. This pocket connection further strengthens the connection between the L-shaped 4pieces and the channel. The connection between the end sill and `the car-bodyis further strengthened by the'insertion of an angle 138, Fig. 12, secured by rivets to the top of the Z-bar on the end sill and to the end of the stakes. -Thecenter plate 25 is rigidly secured to -the end sill by angleirons 139, secured to the center plate and'to the top of the end sill, particularly to the Z- bar, and they are also connected to the angles 138, just described. (See Fig. 12.)I

I do not wish to be understood by referring to channels or angle-irons or anyfsimilar shape to mean that thereis any distinction `forythe purposes` herein used Vbetween the commercial forms, pressed forms, or built up :forms:

NeitherdoI wish to-be limitedtothe' exact IvOO details of construction, which may be varied within reasonable limits without departing from the principles of'my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
