SPECIFICATION formingpart of Letters Patent No. 746,385, dated December 8, 1903. Application filed November 30, 1901. Serial a. 84.211, (in, model.)

To all whom may concern.-

Be it knownthat I, RALPH V. SAGE, a citizen of the United States, residing in the borough of WVestmont, in the county of Oambria and State of Pennsylvania, have invented certain new and useful Improvementsin Hopper Gondola Cars and Doors Therefor; and I do hereby declarethe following to be 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 certain improvements in the construction of railroad-cars, with special reference to that class of freightcars which are known as hopper gondola cars for carrying bulk freight, such as minerals or other materials which may be unloaded by dumping through hoppers arranged in the bottom portion of the car.

Certain of the objects of my invention are to provide an improved form, construction, and arrangement of hoppers, doors for closing the bottom of said hoppers, mechanism for operating and securing said doors, and other particulars, as will hereinafter be more fully described.

My invention, as illustrated and described herein, is applied to a metallic car having a main body substantially rectangular in its va-- rious outlines, the bottom of which is provided with two hoppers, preferably near the center, arranged asa pair, one on either side of the center sills and extending thence to ward the sides of the car. Each of these hop.- pers has the general form of an inverted frustum of a wedge, the parallel sides of which are adjacent to the car sides and the center sills, respectively, the sloping sides thus being located as to extend downwardly from the car-bottom in directions longitudinal of the car.

sloping hopper sides, and the corresponding or adjacent doors on the opposite sides of the longitudinal axis or center sills of the car are secured together by means of a connecting member, so as to move as one piece.

' To the central portion of each of the connecting members intermediate of the doors, which it secures together, I fasten a chain or other similar flexible connection, and said Each of the pair of hoppers, as above 1 described, is provided with double doors, preferably hinged in line to the bottoms of the chains when the doors are in a closed position extend upward in the form of an inverted V and are attached at the apex thereof to a single chain, which passes over an idler-pulley and thence is led to a winding shaft, which shaft maybe provided with any usual or suitable means, such as a wrench or crank, for operating it, and a ratchet, pawl; and locking device for securing it in position for holding the doors closed. These chains or flexible connections and the idler-wheel therefor are located in an open space between the center sills of the car, and thus are not disturbed or obstructed by the car lading, and the single or winding chain is extended in this open space to a convenient point where the winding-shaft is located below the floor of the car, with its end extending through the side in a convenient position for operating by means of the, wrench or crank aforesaid.

By means of the arrangement described I provide a mechanism for operating the doors, the opposite pairs of which are both equally closed and firmly held in closed position whether the individual chains connecting to them are of equal length or unequal length, as the winding-chain by reason of the manner of its connection to the separate or individual chains will pull with approximately equal force upon both of them under the varying conditions above stated, andthis 1s an importantand particular feature on my invention.. a

Having thus given a'general description of my invention, 1 will now in order to make the matter more clear refer to the annexed two sheets of drawings, which form part of this specification, and in which-like figures and letters refer to like parts.

Figure 1 is a side elevation of part of the car-body and hopper, showing the hopperdoors in closed position. Fig. 2 is a vertical longitudinal sectional elevation on the line 13-13 of Fig. 4, taken through one of the hoppers between the center sills and the side of the car, in which the hopper-doors are also closed. Fig. 3 is a vertical longitudinal sectional elevation on the line C O of Fig. 4, taken between the center sills and the adjacent hoppers, the hopper-doors being shown in open position. Fig. 4 is a vertical transverse Figs. and 6 are diagrammatic views of the doors, individual chains, and winding-chain to which the individual chains are attached, showing how both the doors will be equally held in closed position, notwithstanding the fact that either one of the individual chains may be shorter or longer than the other.

Referring now to the various characters of reference upon the drawings, 1 is the side of the car-body, shown as a p ate.

2 represents stiffening members of the side of the car-body, shown as angles.

3 represents the top flanges of the car-body, shown as angles.

4 is the end of the car-body, shown as a plate.

5 represents the stiffening members of the ends of the car-body, shown as angles, and

6 is the main floor covering of the car, shown as plates.

7 is the flat portion of the hopper-doors, shown as plates.

8 is a portion of the stiffening-frame of the hopper-door secured to the flat portion thereof, shown as angles.

9 represents connecting members consisting of rolled channels attached to and securing two adjacent doors together, also serving as stiffening members for the outer edges of said doors.

10 represents the door-hinges.

11 represents reinforcing members secured around the lower portion of the hopper, shown as angles, and 12 represents connection or eye platessecured to the connecting-channels 9.

One of the features of my improvement is the use of rolled-steel channels of commercial form for connecting the doors together, as this shape or section of material is one of the most economicalwhen considering the stresses to which it is subjected. The material of a channel subjected to bending in a direction parallel with its web is so disposed as to offer a great resistance, owing to the economical distribution of the material in the web and flanges and is much better in this respect than an angle. This channel form of connecting member also has a further advantage in that the eye-plate for securing the chain thereto may be riveted directly to the back of the channel in an economical and eflicient manner, the arrangement of parts being such that the rivets are in shear, which is the proper arrangement in accordance with good practice in this respect. This simple form of connecting member and eye-plate has the further advantage of being economical in constrnction, as. the work of securing them together may be done by punching cold and riveting or bolting together after the usual manner of structural work, besides which the component parts are ordinary commercial shapes which can be readily and cheaply procured at all times,

13 represents the separate or individual chains, one of which is, attached to each pair individual or separate chains being merged in one winding-chain 1 1, as shown.

15 is an idler sheave for the windingchain 14.

16 is the shaft for the sheave 14.

17 represents bearings for the sheave-shaft 16, secured to the center members or sills 22. 19 is the winding-shaft for the chain 14.

18 is a ratchet-wheel secured to the ratchetshaft 19.

20 is a pawl attached to the car side, as shown, for cooperating with and holding the ratchet-wheel and winding-shaft in position as desired, and 21 is apawl-lock for securing the pawl 20 in closed position.

22 represents the center sills of the carframe, shown in this case of two channels spaced a suitable distance apart with their flanges turned inward.

23 represents connections between the longitudinal sloping bottoms of the hopper and the center sills 22, shown as an angle.

24: represents connections between the longitudinal sloping bottoms of the hopper and the adjoining outer vertical sides of the same.

25 represents reinforcing members secured to the hinge sides of the hopper-doors, shown as angles.

26 represents reinforcing or strengthening members secured to the outside of the exterior sides 27 of the hopper, said reinforcing and strengthening members being shown as angles in this case.

27 represents the exterior sides of the hoppers, shown in this case as vertical plates, which are secured to the side channels and to the other parts of the hopper, as shown.

28 represents other stiffening or reinforcing members for the inner sides of the hoppers secured to the said inner hopper sides 29 and to the other members, as shown, and 29 represents the inner sides of the hoppers, shown as plates secured to the center sills.

30 represents the lower side members of the car-body, shown as channels.

31 represents transverse members extending between the center sills and the lower side members of the car-body and connected thereto, as shown.

32 represents connections for securing the transverse members or channels 31 to the center sill 22, said connect-ions being shown as angles.

33 represents the inclined bottoms of the hopper sloping longitudinally, as shown.

3% is a stiffening-diaphragm secured to and between the center sills 22 by means of the connections 35, and 36 represents the cornerangles of the car-body for stiffening the same and connecting the ends with the sides.

Referring now to Figs. 5 and 6, the former indicates how both the doors are firmly held in closed position, although the left-hand chain may be shorter on account of wear in the other chain or inaccurate adjustment of the chains, while Fig. 6 is a similar illustration in which the right-hand chain is the shorter, and it will be seen upon reference to these figures that as'long as the angle a is less than one hundred and eighty degrees the winding-chain 14 will draw and tighten both the individual chains in a manner such as to hold both the doors tightly closed in spite of differences in the length or adjustments of the connections 13.

On referring to Fig. 4 it will be seen that the outer sides 27 of the hopper are secured to the side channels '30 by means of horizontal flanges 37, formed integral with said plat-es 27, which horizontal flanges rest on top of and are secured to the upper flanges of the channels 30. I may also provide another flange 39 on the plate 27, extending upward in a vertical direction, as indicated in Fig. 1, and at the right-hand portion of Fig. 4, for the purpose of securing a direct connection between the hopper side plates 27 and the car sides 1, as'shown.

On reference to Fig. 2 the longitudinallysloping bottoms of the hopper consisting of the plates 33 are provided with flanges 38 at their upper edges, which flanges rest on and are secured to the transverse members 31, as shown. 7

Although I have shown certain of my improvements in considerable detail, I do not limit myself to the exact and definite particulars of the construction,arrangement, or seetions shown and described, but may use such substitutions and modifications or equivalents thereof as are embraced within the scope of my invention and as pointed out in the claims.
