JOHN HENRY, OF GRAND FORKS, NORTH DAKOTA.

GRAIN-DOOR.

Application filed [February 14, 1911.

To all whom it may concern:

'Be it known that 1, JOHN HENRY, citizen of the United States, residing at Grand Forks, in the county of Grand Forks and State of North Dakota, have invented new and useful Improvements in Grain-Doors, of which the following is a specification.

My present invention has to do with grain doors for cars; and it has for its object to provide a simple door calculated to with stand the rough usage to which analogous doors are ordinarily subjected, and constructed with a view to being quickly and easily opened when it is desired to discharge grain or other substance carried in bulk I from the car.

The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of specific embodiments thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings'which are hereby made a part hereof: Figure 1 is an elevation, partly in section, illustrating my novel door as it appears-from the outside of the car. Fig. 2 is an enlarged vertical section taken in the plane indicated by the line 22 of Fig. 1, looking toward the left. Fig. 3 is an enlarged horizontal section taken on the line 33 of Fig. 1, looking downward. Fig. 4 is a view taken'at a point within the car' and illustrating one section of the door as lifted out of operative position and fastened out of the way against the side wall of the car. Fig. 5 is a horizontal section taken in the plane indicated by the line 55 of Fig. 4, looking downward. Fig. 6 is a detail section taken on line 6-6 of Fig. 4 and showing the fastener for securing the door section in idle position. Fig. 7' is a view'taken at a point within the car and illustrating as closed a modification of my invention hereinafter referred to in detail. Fig.8 is a horizontal section taken in the plane indicated by the line 88 of Fig. 7, looking downward.

Referring by letter to the said drawings, and more particularly to Figs. 1 to 6 thereof: A is the door opening in the car wall. Above the saidopening A a recess or space B is provided withwhich communicate small recesses C in the door posts D, as will be understood by comparison of Figs. 2 and 4. The communicating space B and recesses C are designed to receive the Specification of Letters Patent.

Patented June 11, 1912.

Serial No. 608,510.

cesses 0 in the posts D, as clearly shown'by 4 full lines in Fig. 2, the upper and idle position of the bar being indicated in the same figure by dotted lines.

Rabbets F are suitably provided at the inner sides of the door posts D, and connected to the inner sides of the posts are keepers G which terminate in outwardly extending portions d, Figs. 3 and 4, which portions d are spaced from the outer walls of the said rabbets F. It will also be observed by referenceto the drawings that a strip H, preferably of metal, is arranged at the lower end of the door opening A, and

that small strips I, Figs. 2, 3 and 4, are

' side of one of the door posts D for a purpose hereinafter set forth.

In addition to the parts thus far described, my novel door comprises a movable door section K and a movable door section the said sections being preferably, though not necessarily, connected with the car wall through the medium of chains M. By reference to Figs. 1 and 2, it will be seen that the section K is provided with a hook e toengage the bar.E and hold the section 'thereagainst, and that said section K is also provided on its outer side with a projection f, and with a swinging latch g, and a locking bar it therefor; the projection f being arranged near the lower end of the section so as to permit of the ready interposition of a crowbar between it and the plate or strip H, and the latch g and locking bar it being so arranged relative to the keeper J that the latch can be swung into engagement with the underside of the keeper J so as to hold the door down, and being designed to be retained in said engagement by the locking bar 72. in the position shown in Fig. 1. When the locking bar it is swung on its pivot i away from the latch g, the said latch is free to swing out of engagement with the keeper J, and then the door section K can be raised rectilinearly by a prying instrument positioned between projection f and strip H.

For the purpose of holding the door section L down, I provide the said section on its outer side with a thin projection j which is adapted when the section is placed in its closed position, to assume a position directly under the bar E. From this it follows that when the bar E and door section L are relatively arranged, as shown in Fig. 1, the bar E will operate to prevent rectilinear upward movement of the section L.

While I prefer to employ some suitable means, the devices described, for instance, for holding the door sect-ions K and L down in their working positions, I do not desire to be understood as confining myself to the employment of means for the purpose, inasmuch as when deemed expedient the weight of the sections K and L may be depended on to hold the same against casual upward movement.

The opposed edges of the sections K and L are inclined slightly from the vertical, Figs. 1 and 8, so that the section K is slightly wider at its upper end than at its lower end, while the lower end of the section L is wider than the upper end thereof. It will also be observed that the section L is provided at its outer side with a flange that extends beyond its inner edge, and is designed to break joints with the inner edge of the section K, so as to prevent the escape of grain or other substance between the opposed edges of the sections when the same are closed. At their outer edges and inner sides the sections K and L are rabbeted throughout their height so as to afford narrow outer edge portions Z designed to rest in the rabbets F of the door posts and between the outer walls of said rabbets and the outwardly directed terminals cl of the keepers G on the posts. 7

For the purpose of fastening the sections K and L against the inner side of the car wall and out of the way when said sections are not in use, I prefer to employ the means illustrated in Figs. 4 to 6, with reference to the door section K, it being understood that similar means will be employed in connection with the door section L. It will be observed that one end of the section K is arranged at the inner side of an angle plate P, and that the other end of the door is engaged by a spring fastener B, so that when the door rests on the ledge S provided '7 and 8 comprises door sections K", L and for its support, the door or door section will be securely held against casual displacement. The fastener R is, because of its resiliency, movable at right angles to the car wall and also in a plane or planes parallel to said car wall, and from this it follows that the plate 25 on the fastener may be readily engaged with the adjacent end of the section K, to secure said section, and may as readily be disengaged from the end of the section to release the same.

ments is as follows: When the sections KY and L are closed, as shown in Figs. 1, 2 and 8, and it is desired to open the door, the latch g is disengaged from the keeper J, and then the section K is raised rectilinearly by a crowbar or other means until the grain adjacent the door has run out. Then the section K is pushed into the car, after which the operator takes hold of the upper end of section L and cants or pulls saidend toward the remote side of the doorway, when the grain adjacent said section L will pass out between the outer edge of the section L and the adjacent post, and will also run out below the raised portion of ,the lower edge of the section L.

To close the door, the section L is positioned as shown in Figs. 1 and 3, with its reduced edge Z in the rabbet F and between the keeper G and the outer wall of the rabbet, and so that the lower end of said section rests between the strip H and one of the opening A is accomplished, and that there is no liability whatever of the door bulging outward under the pressure of grain within the car, and no liability of either of the sections K, L being casually displaced. After the sections K and L are removed to permit the passage of grain through the door openling, the bar E can be readily adjusted so as to leave the door opening entirely clear.

While convenient for the purpose of hold- .ing the door sections K and L against the bar E and the outer walls of the rabbets F,

the hook c and the keepers G or other de- .yices for the same purpose, are not essen- -tial to the successful practice of my invention, and therefore such devices may be omitted without involving departure from the scope of my invention as claimed.

The modified construction shown in Figs.

posts D and the keepers J, as well as the.

strips H and I on the car floor, in the same manner as the before described sections K izo and L. The inner edges of the sections K and L are inclined slightly from the vertical and so that said edges converge downwardly. It will also be seen in Fig. 8 that the sections K L are provided at their outer sides with flanges W which extend inward beyond their inner edges and are continuous throughout their length. These flanges, when the parts are positioned as shown in Figs. 7 and 8, serve to break oints with the intermediate section M and in that way preclude the escape of grain or other substance carried in bulk between the opposed edges of the sections.

lVhile I have shown and described certain forms of my invention, it is to be understood that I am not limited to the details or the form or relative arrangement of parts disclosed, but that modifications may be made therein without departing from the spirit thereof.
