GRAIN-CAR DOOR.

Application filed April 30, 1924'. Serial No. 710,041.

To all whom it may concern- 'Be it known that I, Kazmrrnnz- GoRNY, a

citizenv of the United States f America, re

siding at Bufiialo, inthe county of Erie and State of New York, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is, a specification.

This invention. relates to new and useful improvements. in grain ear doors. a

An important. object. of the invention is to provide a door which may be readily and quickly applied to ordinary freight car doorways for adapting such cars for handli-ng granularmaterial; r

A further object of the invention is to provide improved means for bracing such doors andfor permitting the gradual unloading of the material banked against the moved and av preliminary discharge opening has been provided, 1

Figure 3 is a longitudinal vertical sectional view of a fragmentary portion of a freight car and illustrates the inner side of the grain doors and the manner of mounting the same, also, the preliminary opening for aiding in unloading the material banked against the doors, V

Figure l is a transverse horizontal sectional view taken upon line IV-IV of Fig. 1, V

Figure 5 is a transverse sectional view taken upon lines V-'V of Fig. 1,

Figure 6 is a detail perspective view of the upper brace member illustrated in operative position in Fig. 1, and

Figure 7 is a detail perspective view of the lower brace illustrated in operative position in fig. 1. In the drawings, wherein for the purpose oi illustration is; shown a preferred emhodi ment of this invention,the numeral 5 desigates one sidewall of. a. freight car which is provided with a conventional. form of doorway frame 6 positioned within the. freight car.

In Figs.

3. to 5- inclusive the grain car doors 7 and 8are illustrated as being hing edly secured tothe vertical side portionsz ojf the; doorway traine 6. by meansrof'the hinges 9. These doors are preferably formed; of. metaland. are each provided with; atop brace strip 10 extending;transversely along the upper edge of the same and a second brace 11 which extends, transversely of each door and is positioned between. the u 'per 7 and lower edges of these-me. It wilbe seen by inspecting Fig. 3 that these braces,

10 and '11 are permanently secured to the doors. and are arranged onfthe inner sides of the same. The door 7 is also provided with a sealing strip '12 which issecured. to its free longitudinal edge and is adapted for overlapping the free longitudinal edge of the door 81for closing the space: between such edges. In Figs. 2 and 3, the lower" free corners of the; doors 7 and 8 are illustrated'as being provided with cutout portions for forming a rectangularly-shaped opening 13,. the object of which will appear as, the detailed description proceeds. It will, also, be noted that these doors 7 -and*8.-- are provided. of less height than the height. of the doorway frame 6 and for this reason an opening 14 is provided between the upper-transverse I edges of the doors and the tophorizontal portion of the doorway frame 6.

For the purpose of retaining the doors in their closed positions, the door 7 is provided with a slidebolt 15 secured to the inner face 9 of'its brace 10 while the door 8 is provided with a keeper 16, secured to its brace 10,

for receiving the slidebolt 15. For further aiding in bracing the doors in their closed positions, the removable braces 17 and'18, illustrated in detail in Figs. 6 and 7, are provided. In Figs. 1, 2 and 4, the door 7 is illustrated as being provided with a pair ISO of spaced'keepersltl while the door 8 is illnstrated as being provided with one of these keepers 20. It will be seen that these keepers'are permanently bolted to the outer faces of the doors 7 and 8. and are positioned in spaced relation to the upper transverse edges of the same. In Fig. 4 these keepers 19 and 20 are illustrated as being of sub stantially T-shape in cross-section and as providing, with the faces of the doors 7 and 8, guide grooves 21. The removable brace 17 is illustrated in Fig. 6 as consisting of a body portion 22 which consists of a fiat strip of suitable metallic material having transversely extending slots 23 which are suitably spaced for registering with the keepers 19 and 20. The upper longitudinal edge of this body portion or strip 22 is provided with a strengthening element 2 1 which is in the form of an angle iron that is riveted or otherwise secured to the said body portion or strip. In Figs. 1 and 4; this removable brace 17 is illustrated as being positioned in engagement with the keepers 19 and 20 and with the said keepers residing within the slots 23. In Figs. 1, 2 and 5, the doors 7 and 8 are illustrated as being provided with keepers 25 which are of identical construction to the keepers 19 and 20 and are arranged in juxtaposition to the vertical edges of the rectangularly-shaped opening 13. These doors 7 and 8 are also illustrated as being provided with threaded apert 26 which are positioned slightly above the horizontally extending edges of the cutout portions formedin the doors for providing the opening 13. In Fig. 7 the removable brace 18, which is illustrated in Fig. 1 as being associated with the keepers 27, is shown consisting of a body port-ion 27 which consists of a strip of flat metallic material and is provided with the transversely extending slots 28 which are positioned for registering with thekeepers 25. This body portion or strip 27 is also illustrated as being provided with an angular strengthening element 29 which is suitably bolted or otherwise secured to the upper longitudinal edge of the said body portion or strip. The portion of this angle iron 29 which flatly engages the body portion or trip 27 is provided with a pair of spaced internally threaded apertures 30 which are arranged for registering with the threaded apertures 26 formed in the doors 7 and 8. The body portion or strip 27 is also provided with a pair of threaded apertures which aline with the apertures formed in the angle iron 29. In Fig. 1, this removable brace 18 is illustrated as being positioned in operative relation with the doors 7 and 8 and with the keepers 25 residing within the slots 28. There are also il lustrated a pair of lag bolts 31 which are provided with lock nuts 32 and are positioned within the registering openings 26 and 30 formed in the doors 7 and 8 and the removable brace 18. It will be apparent that these lag bolts 31 will retain the brace 18 against accidental removal. It will also be apparent by inspecting Figs. 1 and 2, wherein the removable brace 18 is shown as properly positioned and removed, that the central portion of the body or strip 27 acts as a closure for the rectangularlyshaped opening 13.

In Figs. 1, 2, i and 5, there is illustrated a reinforcing strip 33 which is secured to the floor portion of the doorway and is illustrated as having its opposite ends turned upwardly for being secured to the vertical side portions of the doorway frame 6. This reinforcing element is positioned outwardly of the lower edges of the doors 7 and 8 and acts as a means for further preventing the outward forcing of these doors, due to the weight of granular material bearing against the inner faces of the same.

In Figs. 1. and 2, the outer face of the door 7 is illustrated as being provided with a handle 34- whioh may be employed for aid-' ing in forcing the doors inwardly after a portion of the material has been removed from the interior of the freight car. In Fig. 3, the side wall 5 is illustrated as being provided with eye bolts 35 which are adapted for receiving the hooked ends of the hooks 86 secured to the inner faces of the doors 7 and 8. It will be apparent that these books and eye bolts are provided for ing the doors 7 and 8 in their open 1 and 2, there is illustrated the mal form of sliding door 87 which forms a part of the standard equipment of an ordinary freight car. It is intended that this door be retained even after the improved grain car doors have been applied to the opening. This door 37 is illustrated as being slidably carried by the track elements 38 and 39 which are arranged above and below the doorway. Any conventional form of stop, as illustrated at 40, may be provided for restricting the sliding movement of the door 37.

The operation of this improved form of grain door is as follows Prior to the filling of a freight car equipped with these grain doors, the latter are swung into their closed positions and the bolt 15 moved into engagement with the keeper 16. The removable braces 17 and 18 are also positioned in engagement with the keepers 19, 20 and 25 and the lag bolts 31 are screwed into the threaded apertures 26 and 80. The lock nuts 32 are then moved along the lag bolts until they bind against the outer face of the angle iron 29 thereby retaining the bolts 81 against accidental loosening or removal. It will now be apparent that the small rectangular opening 18 formed in the bottom portions of the doors 7 and 8 is closed while the opening 1% is left unobstructed. This opening 1% is intended to be employed for feeding granular material into the freight car by means of a conveyor chute or other suitable means. After the car has been filled with grain or other similar material, the door 37 is preferably moved into its closed position and locked in any suitable manner. After the car arrives at its destination, the door 37 is to be unlocked and moved into its open position. removed for permitting the removal of the brace 18. This withdrawing of the brace 18 from engagement with the keepers 25 will uncover the opening 13 through which the granular material will gradually be discharged. This opening 13 may also be employed for shoveling the portion of the material bearing against the doors 7 and 8 which wiil not be automatically expelled through the opening 13 by the force of gravity. After the brace 18 has been removed, it will be apparent that the element 33 will prevent the outward bulging of the lower portions of the doors 7 and 8, due to the pressure against the inner faces of the same. It will now be apparent that after enough of the material has been removed from the interior of the car for permitting the doors 7 and 8 to be swung inwardly, the upper removable brace 17 may be removed and the sliding bolt 15 disconnected fron the keeper 16. The doors 7 and 8 may then be forced inwardly for permitting the entrance of laborers who will continue the operation of unloading the car.

It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the The lag bolts 31 may then be.

same, and the various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I claim In a device of the type described, the combination.with a freight car having a doorway frame, of a pair of inwardly opening doors hingedly connected to the, frame and having their lower free corners similarly cutaway to jointly form a discharge opening, a se ies of outwardly extending T- shaped keepers fastened to the outer faces of the doors near their upper edges, a brace member having a series of slots to receive said keepers when the brace member is arranged transversely of the doors and resting upon the keepers, an additional outwardly extending T-shaped keeper carried by each door at the vertical edge of its cutaway portion, second brace member having a pair of sl to receive the said additional keepers when the second brace member is arranged transversely of the lower edges of the doors with the intermediate portion of the same closing the discharge opening, and a permanent bracing strip secured to the floor portion of the doorway frame against which the lower edges of the doors are braced to withstand internal pressure.

In testimony whereof I afiix my signature.

KAZIMIERZ GORNY.
