DUMPING BOX-CAR.

SPECIFICATION forming part of Letters Patent No. 684,574, dated October 1901- Application filed March 2, 1900. Serial No. W078. (No model.)

To all whom it may Camem- Be it known that I, FRANK S. INGOLDSBY, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Dumping Box-Oars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to combine into one structure a car which may be used as a dump-car (suitable for carrying wheat, for example) or for ordinary package freight. In accomplishing this I provide a car having trap-doors in its bottom, which may be lowered to dump the contents, and above these doors a false bottom, which may be turned up along the side of the car to convert the car into a dump-car or may be lowered to cover over the trap-doors, converting the car into what is commonly known as a box or furniture car.

The invention consists of a car having these features and includes the more specific adaptation thereof hereinafter described, and definitely set out in the claims.

In the drawings which clearly disclose my invention, Figure 1 is a side elevation of the car. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a transverse section, and Fig. is a plan of one of the floors which constitute the false bottom. The last two figures are on a scale twice the first two.

The same letters of reference designate the same part in each figure.

The car-body includes the longitudinal sides a, each of which may be trussed and may have one or more openings or doors a the roof a and the floor-framing consisting of the end structure a and the central longitudinal and cross beams a and a respectively. All of these floor members have their sides inclined, as shown, the end frames a having their upper surfaces, composed of the horizontal sheathing a and the inclined sheathing a supported by suitable sills or beams. The space between the various floor members is adapted to be closed by the trap-doors B. These doors are constructed and operated substantially as shown in my prior patents, No. 551,319, No. 613,279, and No. 632,650, issued,respectively,December 10, 1895, Novemher 1, 1898, and September 5, 1899. Briefly, the mechanism is as follows: Each door B is beveled at its edges and adapted to thus make a tight contact with corresponding bevels along the sides, ends, and central beam of the car. The doors are supported by straps 0, se cured to their upper side, which are pivoted at c beneath the central longitudinal beam and have their outer ends extending in the form of beveled hooks 0 beyond the edge of the car. These hooks are engaged by coopcrating beveled hooks on the lower ends of levers D, pivoted to the side of the car and connected together by a link E, connected to the operating-lever F. Thus when this lever is thrown forward the hooks of the levers D are released from the hooks of the straps O and the doors fall by gravity.

The pivots c of the door-straps are in the upper corners of struts G, secured to the under side of the central longitudinal beam, and in these struts are j ournaled operating-shafts H, which carry pinions h, meshing with segments J, secured to the under side of the doors. The shafts H are geared to two diagonal shafts K, which in turn are geared to the vertical shafts L, adapted to be rotated by the hand-wheelsl at the top of the car. Thus the rotation of either hand-wheel rotates the cor responding pinions h, which, operating on the segments J, elevate the doors on that side of the car, and when elevated the doors are tightly locked in place by the cooperating bevels of the levers D and the straps O, as stated.

Now within the car, hinged to its sides, are floors or doors M, which may constitute a false bottom or be turned up against the sides of the cars,being there held by suitable means, as the buttons m, carried by these sides. The upper surface of the end framing a beyond the ends of these doors is flat, as shown at a; but suitable end floors P are adapted to occupy an inclined position above the part a in the car, continuing the incline a of this end framing. Thus when the floors M are turned up out of the Way, as shown in the right-hand half of Fig. 2, and the end floors P are spread down the car is converted into a dump-car. On the other hand, when it is desired to convert the car into an ordinary box or furnitre car the end floors P are moved into a vertical position, as shown at the lefthand end of Fig. 2, being held in this position by suitable means, (as the cleats a and at extending across the car at the floor and near the roof at the end,) and the floors M are lowered, resting at their ends on the end frame a and the cross-beam a and at their free edge along the longitudinal beam at. Thus a car is provided with a flat continuous floor adapted to satisfy the uses of the ordinary box or furniture car.

The end floors P are preferably three in number at each end of the car, so that their position may be changed by one man. They have on the under or outer sides lugs 19 and 19 which in the inclined position of the floors take into socket-plates p and 19 set into the end of the car and the floor-surface a", respectively. These socket-plates are of an ordinary form, having, preferably, a rectangular opening for the reception of the lug. Suitable countersunk handles p are provided on the face of the doors for conveniently raising and lowering them. When the car is to be converted into a box-car, the doors are simply lifted up into the vertical position by these handles, the upper edge passing behind the rabbeted cleat a and lower edge being lifted over the floor-cleat a and set down hehind it, the lugs 19 10 taking into recesses provided for them in the end of the car. The floors M are also removably secured to the sides of the car. These floors are constructed of suitable planking supported on their under sides by deck-beams The webs of these deck-beams merge into their base-plates near their ends, and these ends are countersunk into the edges of the planking. Thus along the free edge of this floor the countersunk ends are seen at m, while at the opposite edge they are bent into the hooks m which take into staples m in the side of the car. When the floor is horizontal, the hooks may be removed from these staples by elevating the outer edge of the floor. As soon as the elevation of the inner edge is begun, however, in the swinging up of the floor the hinging becomes positive. Suitable countersunk elevating-handles m may be provided near the edges of the floor to turn it up on its hinge to convert the car into a dump-car and to provide for the convenient removal of the floor altogether when desired.

By bending the base of the deck-beams m up along the front edge of the floor at one end and into the countersunk pivoting-hook at the other I not only make aver-y cheap construction,but supply a very rigidly-braced floor and provide the pivot thereof near the upper edge of the fioor, whereby it may be also near the side of the car. Thus a very eflicient hinge is provided.

It will'be noticed that when the floors M are vertical they extend across the entrance or openings 0. through the sides of the car, and

thus no additional guard is necessary to close these openings when the car is being loaded with grain or other material which would press against and prevent the closing or opening of the outer doors of the car. The base of the car in this position consists (by reason of the inclined walls of its openings) virtually of four hoppers, open above and closed below. When the floors M are let down, these hoppers are closed above on a line with the permanent horizontal flooring of the car.

The bevel on the longitudinal edge of the floors M not only cooperates with the inclined upper surface of the central beam, but when the floors are turned up prevents lodgment of material on the edge. When the floors are turned up, the exposed under'beams m being verticaliof course forrn no lodging-place for material, while as to the end floors P it is to be noticed that the same surface is always exposed to the load, so that whether these floors are inclined or vertical no obstruction results.
