DUMPING-CAR CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. 8, 1914.

Application filed June 10, 1913. Serial No. 772,746.

T 0 all whom it may concern:

Be it known that I, RALPH V. SAGE, a citizen of the United States, residing in the borough of WVestmont, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Car Construction; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railway cars and more particularly to the manner of constructing the lower portions of sides of a dumping car. n

One of the objects of my invention is to provide a simple, strong and economical construction for a car side, and more especially adapted for that class of freight cars known as drop bottom gondolas in which the floor of the car is composed of a plurality or series of hinged doors located between narrow floor strips extending transversely from each side of the center sills.

Another object of my invention relates to the construction of the corner shedding plates for the car and the improved manner of bracing the same by means of a flanged bracket member, whereby the lower end of the side stake, the outer end of the cross bearer and the shedding plate are rigidly secured together, while the shedding plate also forms the lower chord of the plate girder.

A further object of my invention is to mount the door operating shaft in journal bearings so arranged that the weight of the lading on the door operating shaft will be directly sustained by the girder side of the car.

Referring now to the accompanying two sheets of drawings forming part of this specification, in which like characters of reference designate like parts :Figure 1 is a top plan view showing a little more than half of a car, in which drop doors are located on each side of the center sills and form the greater part of the floor of the car. Fig. 2 is a side elevation of that portion of the car shown in Fig. 1. Fig. 3 is an enlarged side elevationof the lower end of one side of the side stakes and the adjacent portion of the shedding plate and door operating shaft. Fig. 4: is a transverse section of 16 is a vertical transverse section of a portion of a car taken on the same line as Fig. 4, but illustrating slightly modified forms of the shedding plate, bracket member and journal bearing for the operating shaft. Fig. 7 is a detail sectional elevation taken onthe line VIIVII of Fig. 6 looking in the direction of the arrows.

Referring to the numbers of reference on the drawings :1 indicates the center sills of the car which are shown as rolled channels arranged with their webs vertical and back to back, and with their flanges extending horizontally outward toward the sides of the car, and spaced apart by means of shallow flanged box-shaped members 2 and 8. The center sills, however, may be of any other form or arrangement. A cover plate 4 is riveted t0 the top flanges of the center sills 1 and to the top flanges of the boxshaped members or diaphragms 2 and 3 and serves as the central floor strip of the car.

The car bolsters are preferably constructed of open side box-shaped members 5 of trapezoidal form having their vertical webs placed back to back with outwardly extending integral flanges around the edges thereof. The inner flanges of these bolsters are riveted to the center sills together with the flanges of the spacing members 3. These members are further secured together by means of a bottom plate 6 and a topcover plate 7 which is laid over the bolsters and forms the floor ofthe car at this point, as shownin Fig. 1. The outer ends of the bolster members 5 are of less depth than their.

inner ends and have their flanged edges riveted directly to the lower ends of the side stakes 8 of the car as may be seen on referring to Figs. 1 and 1 of the drawings.

9 indicates the cross bearers, spaced at suitable distances apart between the bolsters, each composed of an elongated rectangular pressed metal member with a vertical web and integral flanges extending at right angles thereto entirely around the outer edges thereof; the inner flanges of each of said members 8 being riveted to the center sills and to the flanges of the spacing mem bers 2 between the center sills as shown. Narrow floor plates 10 are riveted to the u per horizontal flanges of the cross-bearers 9, but of slightly greater width than the said flanges, thus projecting beyond the same for the doors 11 to close against and on a plane with the cover-plate 7 of the bolsters and the central longitudinal floor plate 4.

,The plate girder sides of the car are constructed of plates 12 with a guard angle 13 secured at the top, forming the upper chord and stiffener thereof, the lower part of the said plates being bent inwardly at an angle near their bottom edges as shown at 14, thereby forming shedding inclines and part of the lower chords of the side girders. A lower member 15 comprising a bent plate of substantially V-section is arranged upon its side with one of its legs 16 extending horizontally outward toward the outside of the car and resting on the top of the cross bearers 9 and on the car bolsters, to both of which it is riveted, while the other leg is inclined upwardly with its upper end under and riveted to the lower end of the in clined shedding plate 14. This member 15 forms the lowest part of the lower chord of the plate girder side and shedding plate.

The outer ends of the cross bearers 9 and the bolster members 5 are attached directly to the downwardly projecting lower ends of the side stakes 8 of the car, and to further strengthen the sides of the car and the inclined shedding plate portion at these points, a bracket 17 is provided, comprising a vertical web extending transversely of the car with an upright flange bent at right angles thereto as shown at 18, the upper portion of which is riveted to the side stake 8, and its lower portion is riveted to the lower part of said stake, together with the flanged outer end of the cross bearers 9, or those of the bolster members 5. The upper inner edge of this bracket 17 is inclined to conformwith the incline of the shedding plate 14 and member15 and is flanged as at 19 and riveted to the said inclined shedding plate and to the upper inclined leg of the V-shaped bent plate 15, as shown. Slits are formed in the horizontal leg of the V-shaped member as shown at 20 and in the top flange of the cross bearers 9 and bolster members as shown at 21, so that the bracket 17 may pass through them at these points.

A short angle bar 22 is riveted to one side of the lower end of the car stake and to the vertical side of the outer end of the cross bearer 9 to give additional strength and stiffness, and more securely connect the stake and cross bearer together.

A journal bearing 23 is formed on the lower central portion of the bracket 17, as shown in Figs. 4 and 5, in which the cylindrical journal opening has an integral annular flange 24 extending therefrom around the edge thereof; but a separate casting or forging 25 may be used for this purpose, as disclosed in Figs. 3, 6 and 7.

' The door operating shaft 26 extends longitudinally of the car and on each side thereof. As illustrated, only one shaft is shown, but it will be understood that the other side ofthe car is constructed similarly. Suitable door operating mechanism 27 is mounted thereon, as shown, and connected to the car doors. Any desired mechanism may be used, but I prefer to use that disclosed in my patent No. 942,108, dated December 7th, 1909, but as this forms no part of my present invention, a detailed description thereof is not given herein.

The operating shaft p asses loosely through perforations 28 near the outer central ends of the cross bearers 9 and the bolster members 5, but these perforations 28 do not form bearings for the door operating shaft 26 as this shaft is entirely supported directly from the plate girder car side by the brackets 17 as before stated.

In Fig. 6 I have illustrated a slightly modified form of an inclined shedding structure and lower chord, in which the lower edge of the web of the plate girder side 12 ends in a short inclined flange 29 which overlaps and is riveted to a narrow strip 30 having its inner end attached to the inclined flange '31 of the vertical edge plate 32, and the forward edge of thedoor, when closed, contacts with the bottom edge of said plate 32, instead of the lower horizontal flange 16 of the V-shaped bent plate shown in the other drawings. In this modified form the bracket 17 has greater width and its upper face is inclined at a less angle, otherwise the structure is substantially the same.

In the car structure shown the inclined shedding plates and longitudinal attachments also form a bottom chord member for the plate girder sides which is well adapted to withstand the strains, due to loads thereon, and by reason of its width and construction, also braces the same laterallyand holds it in correct alinement.

YVhile I have shown and described my invention in considerable detail, 1 do not wish to be limited to the exact details of construction specified, but may use such substitutions, modifications or equivalents thereof, as are embraced within the scope of my invention, or as pointed out in the claims.

hat I claim as new and desire to secure by Letters Patent is 1. In a car of the character described, provided with a plurality of drop bottom doors, a longitudinal center sill to which said doors are hinged, plate girder sides, bolsters and intermediate cross bearers attached to said sill, extending outwardly therefrom and attached to the plate girder sides, longitudinal door operating shafts extending through perforations in the outer ends of the cross bearers and bolsters, each of said plate girder sides having a vertical upper portion with stakes attached thereto and extending below the same, and a lower inwardly inclined portion forming the bottom chord member thereof, a plurality of flanged brackets each having a vertical web spaced apart from the cross bearers or bolsters with their flanges attached to the downwardly extending portions of the stakes and to the said inclined portion and depending therefrom, and journals formed in said depending portions of the brackets adapted to revolubly support the door operating shafts independent of the cross bearers and bolsters.

2. In a car of the character described, provided with a plurality of drop bottom doors, longitudinal center sills to which said doors are hinged, plate girder sides, bolsters and intermediate cross bearers attached to said sills, extending outwardly therefrom and attached to the plate girder sides, longitudinal door operating shafts extending loosely through perforations in the outer ends of the cross bearers and bolsters, each of said plate girder sides having a vertical upper portion with stakes attached thereto and extending below the same and a lower inwardly inclined portion with a bent plate attached to its lower edge forming the bottom chord member thereof, a plurality of flanged brackets each having a vertical web spaced apart from the cross bearers or bolsters with their flanges attached to the downwardly extending portions of the stakes and to the said inclined portion and depending therefrom, and journals formed integral in said depending portions of the brackets adapted to revolubly support the door operating shafts independent of the cross bearers and bolsters.

3. In a car of the character described, pro vided with a plurality of drop bottom doors, longitudinal center sills to which said doors are hinged, plate girder sides, bolsters and intermediate cross bearers attached to said sills, extending outwardly therefrom and attached to the plate girder sides, longitudinal door operating shafts extending loosely through perforations in the outer ends of the cross bearers and bolsters, each of said plate girder sides having a vertical upper portion with stakes attached thereto and extending below the same, and a lower inwardly inclined portion with a bent V shaped plate attached to its lower edge forming the bottom chord member thereof, a plurality of flanged brackets each having a vertical web spaced apart from the cross bearers or bolsters with their flanges attached to the downwardly extending portions of the stakes and the said inclined portion and depending therefrom, slits formed in the outer ends of the cross bearers and in one of the legs of the V shaped plate through which the web of the flanged brackets pass, journals formed integral in said depending portions of the brackets adapted to revolubly support the door operating shafts independent of the cross bearers and bolsters, and a stiffening angle attached to the lower end of each side stake and to the outer end of each cross bearer substantially as described.

In testimony whereof I hereto affix my signature in the presence of two witnesses...
