HOPPER-CAR.

, Specification ot Letters Patent.-

Patented Sept. 2, 1.913.

Application filed. December 20, 1912. Serial No. 737,784.

To all whom it may concern Be it known that I, AnoYLn Caurnnnn, a citizen of the United States, residing in .(Jhicago, in the county of Cook and State of Illinois, have invented a new and useful Im provement in Hopper-Cars, of which the following is a specification.

This invention relates to improvements in hopper cars, and more particularly to the operating mechanism for the hopper doors thereof.

()no object of the lIlVOlltiUZl is to provide a hopper car of a simple, strtiig, el'licient and dhrablc construction, provided with operating shafts which are common to several sets of hopper doors and adapted to operate the latter simultaneously.

Another object of the invention is to provide an operating mechanism for the hop )er doors, of few parts and minimum number of shafts, to thereby decrease the cost of construetion and save time in opening and closing the doors.

Other and more specific objects of the invention are: to arrange the transversely extending operating sha'tts in such a way that it is unnecessary to out the center sills, which would thereby he weakened; to so dispose the operating shafts that the same are below and exterior to the hoppers; to provide space between some of the sets of hoppers for cross ties, and to provide novel means for adjusting the length of the con neetions between the hopper doors and the winding drums of the door operating mechanism.

The invention furthermore consists. in the improvements in the parts and devices, and in the novel combinations of parts and devices herein shown, described or claimed.

In the drawing forming a part of this specification, Figural is a top plan view of half of a hopper car having my improvements embodied therein. Fig. 2 is a longitudinal, vertical section of'the structure shown in Fig. 1 and taken substantially on the line 2+2 thereof. Fig. 3 is a trans verse, vertical section, taken on the line 3-3 of Fig. 1. Fig. 4 is a detail, vertical sectional View, upon an enlarged scale, showing parts of the door operating mechanism. Fig. 5 is a transverse, detail, sectional view taken substantially on line 5-.''') of Fig. 4. and showing parts oi the operating mechanism, and Fig. (5 is a detail sectional view, taken substantially on the line (k-6 of Fig. 5.

In said drawing, my improvements are shownas applied to a hopper car of the type generally known as the seventy ton, flat bottom hopper car which, as usually constructed, is provided with twelve hoppers arranged transversely of the car with six hoppers on each side of the center sill, but, as will he understood, the improvements are susceptible of use on other types of hopper cars.

The carbody is designated generallyby the reference A, and as shown is provided with a plurality of transversely extending hoppers 13, said hoppers B being arranged in sets of four. The drawings in Figs. 1 and 9 illustrateapproximately a half of a car, said car being provided with twelve ho pers, arranged in three sets of four eac that is, each set comprises two adjacent hoppers on each side of the center sill. The hoppers in each set are divided by vertically extending partitions 10 and the adjacent hoppers of two sets are ,divided by partitions 100. Each hopper B has the bottom thereof formed by means of a pair of hinged, oppositely swinging hopper doors 11, said hopper doors, when in closed position, forming what may be termed a substantially flat bottom, as contradistinguished 't'rom hoppers of the V shaped type. The doors of each set of four hoppers are operated simultaneously by similar mechanism, and I shall only describe the mechanism for operating the doors of one set. This mechanism, as shown, comprises a common, transversely extending operating shaft 12, mounted in suitable dependin brackets 13 at the center of the car, secure to the bottoms of the center sills 14 and suported at its outer end by suitable dependmg brackets 15.. Secured to said she t 12, intermediate the brackets 13, are a pair of winding pulleys 16, to each of which is socured a chain 17, said chains being ada ted to wind upon said pulleys, as will be 0 vious, and being extended in opposite directions (see Fig. 4), and secured to pulleys 18, each of said pulleys 18 being mounted on a short shaft 19, rotatably mounted in suitable hearings 20 secured to the inner sides of the center sills 14. Each of said shafts 19 is also provided with a polygonal drum 21,

having an ofiset lug 22 and a locking face To each lug 22 is pivotally secured, on opg iosite sides thereof, a pair of triangular :-rhaped plates 24:, the latter having pivotally connected thereto, between the same at their onterends, a hook shaped link 25, bifurcated at its lower end, as at 26, and having detach-ably, pivotally mounted within said bifurcations, an eye -bolt 27, adjustably mounted in a threaded, diamond shaped block 28, more particularly described hereinafter. Also pivotally secured to said triangular shaped plates 24, and on the outsides thereof, are a pair of hook shaped links 29, the latter having detachably, pivotally mounted therebetween at their lower ends, another eyebolt 2'4.

Each threaded block 28 is mounted between offset portions 80 of transversely extending channel irons 231, which are secured to the under faces of the hinged hopper doors 11, said channels, as will be under stood, being adapted to operate the hopper doors on each side of the center sill in pairs sinmltaneously, and the block 28 being located centrally of the car beneath the center sills. Each eye-bolt 27, as above described, is dctachably pivoted to the ends of the hook shaped links, as by means of a removable pin 32, and. by removing said pin 32, the eye-bolt may be adjusted within the block 28. it will also be noted that each eye-bolt 27 is provided with a longitudinally extending slot through which is adapted to a cotter pin 3st, the latter being used so as to properly retain the eye-bolt in position within the block 28, and thereby prevent twisting of the connections between the doors and the winding drums. It will also be noted that the block 28 is of substantially the same height as the channel irons 31, and that therefore the adjustment between the eye-bolt and the block is accomplished witlr out extending the eye-bolt beyond the parts of the door. .lach triangular shaped plate 24. is provided with a flat bottom face 35,

' which coiiperates with the locking face 23 of the polygonal drum, the latter being also provided with lugs 36 on the outsides of the triangular members 24, on which rest the.

hook ends of the links 29. The pivotal connections of the hook shaped links are so arranged that lines passing through the centers of the pivotal connections, when the doors are in closed position, will be to one side of the center of rotation of the polygonal drums, so that the load on. the doors will have no tendency to release or unlock the operating mechanism.

From l' ifd'. 2 of the drawing, it will be seen that the partitions 100 between the adjacent hoppers of two sets of hoppers are inewhat shorten-Anon those referenced above the operating shafts. 'Inls arrangement is made so that space is provided for cross-ties 37, secured to the bottoms of the center sills and to the bottoms of the intermediate partitions 100 and the various hopper sheets to thereby provide increased strength for-the car. i a From the foregoing description, it will be seen that I have provided a construction wherein only three operating shafts are required to open and close twelve pairs of hopper doors, whereas, so far as I am aware, it has generally been customary to provide an operating shaft for each pair of transversely arranged hoppers. It will also be noted that the operating mechanism is so arranged that the center sills are not cut away, since the short shafts supporting the po lygonal drums and pulleys are mounted. between the same, and that the operating shafts themselves are entirely exterior to the hoppers, and thus are not likely to become injured by the material of the load.

Although I have herein shown and described what I now consider the preferred embodiment of my invention, yet I would have it understood that the same is merely illustrative, and that all changes and modifications are contemplated as come within the scope of the claims appended hereto.
