ARGYLE CAMPBELL, OE CHICAGO, ILLINOIS, ASSIGNOR TO ENTERPRISE RAILWAY EQUIPMENT COMPANY, 0F CHICAGO, ILLINOIS.

MEANS FOR DISCHARGING GRAIN To all whom t may concern: l

Be it known that I ARGYLE CAMPBELL, a

tates, residing at Chiof Cook and State of Illinois, have invented a 'certain new and useful Improvement in Means for Discharging Grain and Similar Materials from Cars or other Containers, of which the following is a full, clear, concise, and exact description, reference being had tol the accompanying drawings, forming a part of this specilication.

My invention relates to improvements in means. for discharging grain and similar materials from cars or other containers.

As is well known, it is customary for railroads to transport grain and other like bulk materials in ordinary box cars, the closure for the side doors being most frequently formed by means of planks nailed to the door posts. Such cars inthe grain service are not entirely satisfactory for the reason that in unloading cars it is necessary to chop away some of the planks with the result that chips are mingled with the grain and some of the planks are always los't each time the car is unloaded.

While many experiments have been attempted to provide satisfactory means for' discharging grain and likematerials from ordinary box cars, the same have not proven entirely satisfactory, and the expense of providing such carsy with discharge hoppers of usual construction is such that the railroads ordinarily cannot afford the same. As vis well known, it is necessary, in unloading cars filled with grain and the like, to relieve the pressure behind the side door opening closure before the closures can be removed or shifted if the same are permanently attached to the car.

One obj ect of myinvention is to provide a simple arrangement which may be applied to either new or old box cars to adapt them for the carrying of grain and other materials carried in bulk, and without the necessity of incorporating any radicaland expensive changes in the car.

Another obj ect of the invention is to provide a simple and inexpensive discharge chute which may be applied to the side walls of a box car adjacent the usual side door openings and thereby permit the removal of a suiiicient amount of grain from behind the Specification of Letters Patent.

sidedoor opening closures to thereby facilitate unloading of the cars.

Another object of my invention is to provide a relatively small and inexpenslve grain-discharging chute which may be employed 1n conjunction with certain types of grain doors employed on some railway cars, which discharge chute will act as a relief door or auxiliary door for the main grain door.

v The invention further consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described and made the subject matter of claim.

In the drawing forming a part of this specification, Figure 1 is an elevational view of a portion of a side of a box car taken at the center of the car opposite the usual side door opening and illustrating my improvements in connection therewith. In said figure, two applications of my improvements are shown, the full lines indicating my imof the car and the dotted lines indicating the improvement applied to a grain door, in which latter instance my improvements act as a relief or auxiliary door for the grain door. Fig. 2 is an enlarged vertical sectional view taken substantially on the line 2-2 of Fig. 1. And Fig. 3 is a horizontal sectional view taken substantially on the line 3-3 of Fig. 1, and reproduced upon an enlarged scale.

In said drawing, 10 denotes the side wall of a box car of usual construction, said car having the usual side doorv openings indi-y cated by the reference 11. The, floor of the car is indicated by the referencel 12, and 13 indicates a side sill of the car.

Referring to the constru tion illustrated in Figs. 2, 3 and the full line illustration 1n Fig. 1, my improved discharging arrangement comprises, broadly, thev following eleindicated by the reference A, a door or cover, indicated by the-reference B, and a lever, C.

The chute proper A, as shown, is preferably in the form of a casting and has upper and lower outwardly and downwardly extended Walls 14l and 15 and vertical side walls 16--16. At its outer end the member A is formed with a relatively wide flange 17 adapted to lie' against, or be countersunk means-such as bolts',

into, the outer boards 18 of the carwall and be secured to the car wall by any suitable 19%19, extending through said flange and through the wall of the car, as indicated in Figs. 1 and 2.

The thickness, horizontally, of the chute proper A is made such that the inner edge 20 thereof will lie flush with the inner boards 2l of the car wall so as to thereby avoid any undesirable projections on the interior of the car.V At its outer and lower end, the chute proper A is provided with a relatively narrow flange 22 extending all around the chute proper' and defining the exit or discharge mouth thereof. Said flange 22, as clearly shown in the drawing, projects beyond the iiange 17.

he cover B is also lpreferably in the form of a casting and of a suitable size to close the exit mouth of the chute A. Said cover or door B haspreferably integrally formed therewith hinge lugs, indicated at 23, and the casting A has corresponding hinge lugs 24, so that the cover B may be pivotally mounted on its bottom edge by means of the hinge pin 25.

T e cover B is also provided with an inwardly extending flange'26 around all edges thereof an/d so proportioned as to snugly lit over the flange 22 of the member A. In 1 this way, a grain seal is provided whenever thecover is in closed position.

The lever C is pivotally mounted on a headed pin or bolt 27 mounted in a boss 28 .preferablyformed integrally with the chute member A. Said lever C 1s provided with a cam face 29 'adapted to coperate with the corresponding cam rib 30 formed on the outer face of the cover or closure B. The cams 29 and 30 are so formed that as the lever C is swung clockwise to the position shown in the drawings, the cover B will be forced securely against the chute proper A.

o retain the lever C in proper position when the cover B is closed, the member A is preferably provided'with an outwardly extended bracket 3l having an upstanding arm 32 behind which vthe lever C is adapted to engage when the latter reaches its position for locking the cover B. Further, to prevent tampering with the discharging device, the bracket 31 and the lever C are proto manufacture, may be readily applied to old box cars now in service at very small expense, the only expense involved being4 that of the labor required to cut out the necessary opening in the car walls and bolt my device in place. Old box cars thus equipped with my device have a much greater usefulness than the ordinary boxcar; the expense of so equipping box cars is almost inconsequential; and there is no excessive -dead weight or unproductive load added to the car.

Referring to .the'construction indicated by dotted lines in Fig. 1, the discharging device-is-the same in all respects as that hereinbefore described in detail, except that it is applied to a main grain door indicated by the reference D. The latter may be of any Well known design, such-for instance-as those which slide upwardly vertically on the inner face of the car wall for a limited distance and are then swung about pivots so that the door is hooked in inoperative position near the roof of the car.

Although I have hereinv shown and described what I now consider the preferred manner of carrying out the invention, the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

claim:

also be noted that my construction,l in addition to being relatively inexpensive` 1.
