HARRY STILLSON HART, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE ROGER BALLAST CAR COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS. A

METALLIC'CAR.-

SPECIFICATION forming part of Letters Patent No. 700,767, dated May 27, 1902.

Q I Application filed July 3,1899. Serial No. 722,624. (No model.)

To all whom it vnay concern.-

Be it known that I, HARRY STILLSON HART, j a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Cars, of which the following is a specification.

My invention relates to that class of cars which are formed of ordinary commercial iron IO or steel, and has special relation to that class of cars known as ballast-cars, all of which will more fully hereinafter appear.

The principal object of the'invention is to provide a freight-car, preferably of the wellknown ballast-car type,with side plate-girders restingat each end upon asingle self-contained or combinedend sill and bolster, which side girders support-the entire car-body and dispense with the usual side, center, and cross sills, as will be more fully hereinafter set forth.

A further object of my invention is to provide a simple, economical, and efficient metallic ballast-car with two transverse mem- 2 5 bers which take the place of the end sills and body-bolster and by which the car is supported and the shocks incident to use transmitted throughout the entire car.

Further objects of the invention will appear from the following description-and anexamination of the drawings.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of a portion of a car constructed in accordance with my improvements; Fig. 2, a plan view of the same; Fig. 3, a longitudinal sectional elevation taken on line 3 of Fig. 2; Fig. i, a plan sectional view taken on line 4 of Fig. 6 looking in the direction of-the arrow; Fig. 5, an end view of the 'car, and Fig. 6 a transverse sectional elevation taken on line 6 of Fig.

In illustrating and describing my invention I will only illustrate and describe that which I consider to be new, taken in connection with so much as is old as will properly disclose the invention and enable those skilled in the art to practice the same, leaving out of consideration other and well-known parts, which if described here would only tend to prolixity, confusion, and ambiguity. I have also preferred to illustrate and describe my improvements in connection with what is known as a ballast-car for the reason that most of my new features are particularly applicable to this style of car; but it will be understood that some of these features are applicable, with slight mechanical changes, to other kinds of cars-such as gondola, flat, and even box cars-and I do not desire to be understood as limiting myself entirely to the particular type of car illustrated herein.

In the art to which this invention relates it is well known that all or nearly all railwaycars in common use are provided with what are termed end, center, sub, intermediate, and side sills and body-bolsters, which act to support the weight of the parts and load and to receive and distribute the shocks incident to usage. These parts I dispense with and supply novel elements to take their place, and it will be seen from the following description and drawings that these novel elements, as well as the entire structure of the car, are composed of ordinary commercial iron or steel, such as angle and sheet iron, so that when the car is injured and needs repair all that is necessary is to purchase ordinary commercial iron at the nearest depot, which will enable the car to be repaired economically and readily at any point of its run.

In constructingmy improved car I use what I prefer to term a combined end sill and bodybolsterA, one of whichis located transversely at or near each end of the car and by which the load is sustained upon the ordinary truckbolster, not shown or described herein. This combined end sill and body-bolster is com posed of angle-irons a, which extend outwardly in a horizontal plane and act as flanges and to which are secured sheet-metal pieces a,that form the vertical members. and connect the angle-irons together and also take the=-place of a web. An examination of Fig. 3 will show that these web portions are placed parallel to each other and on the inside, extending vertically, and that the angle-irons act as flanges, extending outwardly. In Fig. t it will be seen that the web portions'areseparated considerably, so as to leave a space a at or near the central part, but gradually approaching each other at or near the end portions, where they are secured together and to a vertical plate a which is grasped between them. In Fig. 5 it will be seenthat these combined end sills and body-bolsters are cambered on their lower surfaces, as at a. v

To provide the body of the car and sustain the weight thereof,two side plate-girders B are provided and are formed of angle-irons b at the lower part and b at or near the upper part, between and to which the plate portions b are secured. Each end of these side plategirders is secured to the combined end sill and body-bolster and vertical plate by means of rivets 193, as shown particularly in Figs. 4 and 5, upon which they rest and by which they are supported. It will be noticed from an inspection of Fig. 1 that at or near the end portion and at their upper side these side plate-girders are cut away at an angle from the upper part toward the end, as at b, which in a measure resembles or follows the lines of a parabola, and thus provides maximum strength with the least amount of metal and an approximately equal fiber stress through the total length of the girder.

As above described,I prefer to use the side plate-girders B, which are formed as shown and which in the usual structures will support all the load that it is necessary to carry.

It is desirable, however, at times and under what might be termed unusual conditions to carry heavy loads of ballast, and I therefore reinforce these girders by using intermediate girders and connecting the same together, so as to form what may be termed a box girder at each side of the longitudinal center of the car, but which would only be necessary in connection with cars intended to carry heavy ballast or weights and-unnecessary in other types, such as gondola or coal cars. It is desirable in order to provide for unusually heavy loads to make these side girders as strong as possible, so that the shocks and strains incident to use can be fully absorbed without injuring the car, and.

thus satisfactorily dispense with the side and intermediate sills. To accomplish this result, I provide intermediate plate girders formed of angle-irons O, which are arranged lengthwise of the 'car and secured, by means of rivets and angles at each end, to the combined end sill and body-bolster,and plates 0, which are riveted thereto and which extend in ,a vertical plane and are arranged longitudinally with the car and parallel with and between the side plate-girders. These last-named girders form, with theside girders and the hopper-bottom and floor portions. D and D (which are arranged at an angle, as will be more fully hereinafter explained) and diagonal lattice-bracing L, a box-girder at each side of the car and which are sus tained at their end portions on the combined sills and bolsters.

To sustain the floor of the car, or, in other words, the hopper-bottoms D and D and the inclined ends D thereof, the posts E are provided and secured to the side plate-girders, extending upwardly in vertical planes. I have only shown five of these posts in the drawings; but it will also be understood that I only show one-half of one side elevation of the car. These vertical posts primarily act as stiffeners for the side plate-girders and at their upper ends have secured to them the plates (1 and d, which extend longitudinally of the car and connect with end pieces or angle-irons (1*. These parts dand d practically form a portion of the side of the hopper and are secured to the side plate-girders, as well as to the vertical posts.

The inclined bottoms extend downwardly and inwardly toward the longitudinal center of the car, where they are provided with swinging doors G and G, that meet at the longitudinal apex of the hopper bottom. These doors are opened and closed by means of the chains 9, which run across idlers g and are connected to a rock-shaft 9 The rockshaft is provided with a ratchet 9 which is operated by means of the lever-handle g and held against rotationin one direction by means of the pawl 9 The closing of the door is obtained by vibratory movement of the handle well known in winches and like mechanisms, while the opening is permitted by raising the handle and holding the pawl out of action,thus permitting thedoors to be opened by their own weight and load. These chains, which serve to open and close the doors of the hopper-bottom, are inclosed in a housing formed by means of the plates H and H, as shown particularly in Fig. 3, and which are riveted to the hopper-bottom, as shown in such figure, and act not only as housings, but also as tie-rods for the hopper-bottom.

It is desirable to provide means by which nally therefrom and to which the ordinary draft-rigging may be secured. These draft members are braced against vertical strains and by means of the braces I and 1 which are formed of the platestand angles 11 and i ,as shown particularly in Fig. 3, and extend upwardly and backwardly from the draft members to the inclined end of the hopperbottom, to which they are also secured by means of tie-angles 13 which extend across and tie the intermediate plate-girders together, and thus distribute the strains to such part. These draft elements are also. braced against horizontal strainby means of the plates 2' and '5 which are shown particularly in Fig. 2, and aresecured to the draft elements and the combined end sill andbodybolster.

To assist the combined sill and bolster in carrying the load, I provide .a truss-bar K,

which is riveted at or near each end to the vertical plates 0 and passed over struts K. By this means it will be seen that the load, as well as the weight of the car, is entirely carried onthese combined end sills and bodybolsters,which are strong enough to resist the entire stress and strains. It'will also be seen that the securing of the combined end sills and body-bolsters to the side and intermediate plate-girders, which form the box-girders in combination with the lattice-work L, (shownin Fig. 4,) distributes the shocks due to the bufling and hauling of the cars throughout the entire structure.

End platforms are provided,as usual in such cars, and are formed of plates of sheet metal M, resting on the draft members and secured to the angle-irons m and which are further provided with side plates m. These side angle-irons and plates are also secured to the bottom of the side plate-girders and passed outside of the ends of the combined end sill and body-bolster. to the end of which they are also secured. End postsP are provided, which are secured to the upright members for the draft-bracing by means of rivets and to the angle-irons running across the end of the hopper-bottom and which are used asnected rigidly to and resting on the top of said bolsters, said body being entirely supported from said bolsters'and side girders, substantially as described.
