Application filed September 30, 1904:. Serial No. 226,717.

T all whom it may concern'f Be it known that I, CHARLES VVRIeI-rr, a citizen of the United States, residing at Everson, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Hopper-Cars, of which the following is a specification.

My invention relates to the structure of railway cars and the like for carrying loose material in bulk and particularly to steel cars of the hopper type, designed to dump the load through the bottom of the car. The primary objects of my invention are, to provide aconveniently opened side and bottom for this purpose, in which the load will assist in the dumping; to provide superior means for operating the dumping panels of such a car having hing'ed sides or bottom; to design the frame of the car for more eiiicient support of the body and utilizing all of the possible space for the load; and to generally improve the various parts of the structure of steel cars as will appear more fully in the following description. These objects, and other vadvantages hereinafter to appear, I attain by means of the construction illustrated in preferred forms in the accompanying drawings, where- Figure 1 is a partial side elevation of one end of a car embodying my inventions, showing parts broken away to illustrate several features of construction;

Figure 2 is a vertical cross section through the car on line (2) in Figure 1;

Figure 3 is a central longitudinal section, on line (3) of Figure 2, of one end of the same;

Figure A is a top plan of the frame of the car;

Figure 5 is an underplan view of the entire car body;

Figure 6 is an end view in elevation of the entire car body;

Figure 7 is a cross section, ony line (7) of Figure 8, showing a modified mechanism for operating the dumping panels, and

Figure 8 is a side elevation of one end of the car showing the modifying means of operating the panels.

Vhile the principal features of construction herein shown are as applicable to wooden cars, or others, I have shown for illustration a car constructed entirely of steel. The car frame proper is composed of the side sills 10 the middle cross sill 11 and the end sills 12, beneath which is a longitudinal center sill 13 placed below the plane of the side end and middle sills. From Figures 4 and 6 it will be seen that the end of the center sill 13 is embraced by two halves of the body bolster 14:, and in front the center sill 13 is cut olf at a proper distance, and I form an inclosure for the draft gear attached thereto by means of the two short sills 15 which project forward from the bolster to the end of the car, are supported under the end sills 12 and held securely in place by means of the strap or brace 50 as shown in Figure 6. For added stiffness I provide the struts 16 and the cross braces 17 attached as shown, and the sides 22 of the main body may be braced at intervals by means of the struts 18 shown in cross section in Figure 3. The ends of the body bolster 14 are preferably also braced by hanger straps 19 as shown in Figure 1. By this arrangement practically all the space in the car between the two trucks down to as close as practicable to the track itself provides room for the load, and more room and freedom for the dumping bottom is allowed.

The car body has the sides 22 and sloping ends and 21, and extending between the two wheel trucks as shown particularly in Figures 1 and 2, I provide the longitudinal dumping panels, composed of the side panels 24 pivoted to the side sill at 23 and carrying the sliding panel 26 pivoted to the hinged side panel at and supported at its two ends on rollers 27. These sliding panels 26, as will be clear from the drawings, make a closure at the lower end of the fixed panels 28, which are supported at the top directly on the center sill 13, as by the brackets shown. At each end of the dumping hopper I have attached directly to the center sill 13 a bearing supporting therein a screw 29 carrying a movable head 30, to which are pivoted toggle links 31, by pins 32 which move in a horizontal path guided by the rails 33. As better shown in Figure 6, the toggle links 3l are pivoted at their outer ends to cross thrust links 34 which in turn are pivoted by IOO pins 35 to the edges of the sliding panels 26 of the hopper.

It will be seen from this construction that the turning of the screw 29 by means of the gear 36 and the shaft 38, extending' to the outside of the car and conveniently operated by a ratchet 39 or by any other desired means, the toggle links 3i are drawn inwardly and thrust the bar 34 outward against the movable end of the sliding panels 26 and open them for dumping the car inside of the track. Engaging' the gear 36 fixed on the screw 29, I provide an additional gear and the longitudinal shaft 37 to the other end of the hopper, so that the turning of either one of the screws 29 will operate the screw at the other end at the same time. It will be understood of course that the particular arrangement of the toggle links and the employment of the cross thrust bars is not essential to the invention, but the toggle links may be directly connected by their ends to the pins 35 on the movable panel 26 and their motion reversed, or otherwise arranged as maybe convenient. In the arrangement shown it is seen that the toggle links have their greatest power at the beginning of the motion when the greatest power is needed, and that the weight of the panel after the car has been dumped will tend to render easy the return of all parts to normal position.

From Figure 2 it will be plain that when it is desired to dump the car on the outside of the track the panel 26 may simply be omitted and the liXed panel 2S extended to the outer corner and panel 24 directly operated by the toggle links as heretofore described.

I have shown in Figures 7 and 8 a modified means of operating the dumping panels in place of the toggle link construction just described. Upon a bracket 43 on the depending bulk head 40 at the ends of the hopper heretofore described, I provide a horizontal screw 42 having threads on the two respective sides of the middle running in reverse direction, and upon these I mount traveling blocks 4l which are pivoted to the ends of the sliding panel 26 after the same manner as the links are pivoted in the device of Figure 2. At the center the screw 42 has liXed thereon a sprocket wheel 44, which by means of a chain 47 operates a similar screw at the other end of the hopper. The screw may be directly revolved by means of 'the ratchet 45 on its outer end, which is engaged by a dog and lever 46, as will be plain from Figure 8, or it may be turned by any means preferred.

It will be evident from the above description that the entire available space of the car is taken up with the load, since the fixed panels 28 may be as deep and as close together as may be desired in the design, and all the movable parts are placed outside the hopper and between the car trucks. The load by its pressure will assist in opening' the movable panels, so that very little power will be required, and the dumping may be either inside the rail or outside with very little alteration of the design. The sliding panel 26 being mounted upon roller 27 on a horizontal track will move easily to and from place, and the employment of the side hinged panel 24 will cause the load itself to draw the panel 26 in an outward hori- Zontal direction for dumping, while the parts are returned by their own weight. The various advantages of the structure will be apparent to those familiar with the use of such cars.

Having thus described my invention and illustrated its use, what I claim as new, and desire to secure by Letters Patent, is the following:

l. In a hopper car a dumping panel supported upon hinges and adapted to slide hori- Zontally to open the hopper, substantially as described.

2. In ahopper car the dumping bottom comprising the hinged panels 24 and 2G, substantially as described.
