SPECIFICATION forming part of Letters Patent No. 728,467, dated May '19, 1903. Application iiled February 14,Y 1903. Serial No. 143,348. (No model.)

To all whom may concern,.-

Be it known that I, FRANK S. INGOLDSBY, a citizen of the UnitedStates, residing at St.

Louis, in theState of Missouri, have invented a certain new and useful Improvement in Dump-Cars, 'of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

In the operation of dump cars in vcold weather much difficulty is experienced from the loadv freezing to the car, thus greatly in terfering with its being dumped.

The object ofV thisinvention is to provide simple and efficient means for preventing the adhering of the load to the car. Such means consists, essentially, of a sheathing within the car between its inner surface and the load, the sheathing being so held as toleave a closed space between it and the car. is preferably made of wood. It may be applied to a metal car or otherwise, as desired.

The invention is very adaptable to dumpcars of the Ingoldsby'type, one of the characteristics of which type is a central longitudinal beam having hinged at its lower edges dumping-doors which swing downward at their outer edges. v I'apply the sheathing to the Walls of the car and to the central beam. In each case I prefer to make of thesheathing an additional factor in the easy discharge of the load, reducing the chance of the loads clinging-namely, When the, sheathingis onv the side walls of the car -by incli ning it inward at the top, and when it is on the central beam by causing it to increase the -sloping of that beam. The sheathing is made in such form that it may be removed at any time when it is not desired.

This invention also comprehends the particular embodiment of my sheathing hereinafter more fully described.

In the drawings, Figure 1 is a cross-section through a portion of a dump-car of the Ingoldsby type. Fig.- 2 is alongitudinal section of the same, showing the sheathing on the central beam. Fig. 3 is a side elevation of the end panel of said sheathing. Fig. 4 is an enlarged cross-section of the central beam and the surmounting sheathing. The re- The sheathing l Iber.

maining iigures illustrate details of such sur mounting sheathing, Fig. 5 being a side elevation 'of one of the saddles for supporting it; Y

Fig. 6, a vertical central section across said saddle; Fig. 7, an edge view of said saddle; Fig. 8, a side elevation of` the ridge-Stringer for the sheathing, and Fig. 9 a cross-section `oi' such ridge-Stringer.

The car side is designatedA. It is shown as a plate-girder having at its upper edge a flange ot and at its lower edge a fiange a. The central longitudinal beam consists of a sheetmetal ridge-plate B, having beneath it suit-.

The sheathing for the car sides consists,

preferably, of vertical planks E, secured at varionspoints to longitudinal stringers e. These stringers increase in width from the `bottom ofv the car upward to cause the top of the sheathing` to project inwardly to more effectively4 free the load. At its upper end this sheathing may be supported by brackets e', secured theretoA and extending over the iiange a and there secured by bolts, as e2. The load will hold the sheathing against the car side, though it may be further secured at its lower end bysuitable bolts through the car side. (Not shown.) The space between the stringers e provides a closed air-chamber, which to a very greatextent Aprevents the freezing of the load to the plankingE. A similar construction` mayy be used on the car ends F. The sheathing which surmounts the central beam is designated D. As, shown, it consists of np-and-down planking tongueand-grooved together and presenting a ridge at a considerably-steeper angle than that of the central beam B. This sheathing D is made insuitable panels, of which three for each side of the beam is a convenient num- The planking D is secured to longitu- Vnotches (i7, formed therein.

dinal stringers CZ and d on its under side, and at the ridge the planking on each side is secured to a common ridge-Stringer d2. These stringers rest on suitable saddles d3, which straddle the central beam B. These saddles, as shown, consist of the two boards d4 d4, held together by the two splicing-boards di d5 on opposite sides thereof. Numerous nails or screws hold these parts together. These saddles have at their upper ends recesses d6, which are occupied by the ridge-Stringer d2, the side pieces d4 at the beam projecting into The stringers tl' have formed on their under sides notches d8, extending about half-way through them, and these notches embrace the boards d4 opposite the notches d9 therein, the stringers crossing the boards at these notches. The splice-boards d5 are arranged so that they have edges at the boundaries of the notches d and (Z9, as shown, to form a more efficient seat for the stringers.

By the above means the stringers are each interlocked with the saddles, the saddles holding these longitudinal members and the latter holding the saddle. The stringers are made in sections secured together by spliced joints, as indicated in the case of the ridgestringer in Fig. S, by the overlapped ends du du and the bolts CX12.

Near the upper edge the sheathing D is removably secured by screws d13 to the ridge- Stringer, while at its extreme upper edge the sheathing carries protecting-plates dm, and through these plates are passed bolts (115. Near its lower edge the sheathing is held to the central beam bybolts d1, passing through that beam and receiving nuts on their lower ends. These bolts are countersunk in the sheathing, so as not to form any projection on which the load might clog. At the inclinedends F of the car there are provided saddles'cl, similar in construction and operation to the saddles d3, but inclined.

By making the sheathing in sections and constructing it in the separable manner above set out it is very easy to take it off at the end of the winter season or replace it when desired. In replacing it the saddles are placed along the central beam at about the right intervals. Then the ridge-Stringer (Z2 is put in place and the saddles shifted to bring them to accurate position to interlock with the notches d7 in the stringer. Then one side of the sheathing is put in place, the lower ends of the saddles being slightly shifted, if necessary, to make-them interlock with the notches d8 in the stringers d. The saddles are thereby held accurately in place and the other half of the sheathing is put on, its Stringer CZ interlocking with the saddles. The screws C113 are then turned in and the bolts d15 and d1 are put in place.

The sheathing on the central beam providing a closed air-chamber through which the air cannot freely circulate, but is retained as a heat-insulator,elfectively prevents the freezing of the load to the upper surface. It also gives that upper surface in a steeper form, so that the load will more easily slide olf of it. When the car is loaded, the load itself calks any openings between the planking of the sheathing, thus making virtually sealed air-chambers.

I claiml. A dump-car having its sides protected by a sheathing separated from the car side by an air-space, the sheathing inclined inward at its upper edge.
