To an *w/tom it may concern:

Be it known that we, WILLIAM Glues Doncms, oi the city of lWinnipeg, in-the Province of Manitoba, and lVi'LLmM; Boninson, of the town of Selkirk, inthe Province of Manitoba, Canada, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is the specification.

Our invention relates to rain our doors.

and the object of the invention is to provide a strong, serviceable and inexpensive door, by which grain, coal, and such like produce can .be quickly-unloaded. from the car and which will not allow of-leakage or the grain when in position. v

A further object is to provide a grain door in the construction of which the usual form of rectangular doors at present so widely employed can be utilized.

It consists essentially in a door formed from two similar members, of the same height, which when in position overlap the one on the' other; means carried by the door post for receiving the ends of the door; means for retaining the members in closed position when the car is empty or .loaded; and means for preventing upward displacement of the door, the parts being arranged and constructed hereinafter more particularly described. Figure l is a side elevation of a portion of a car showing the door way opening, supplied withour door. Fig. 2 is a side elevation of t e door in position, and looking. at it from the interior of the car. Fig. 3 is a sectional view through the Walls of the our in the plane denoted by the line X X,

door,the door being closed. l ig. 4 is a similar vlcw to that shown in Fig; 3, the door being shown inthe position which it assumes immediately prior to releasing the grain. Fig. 5 is an enlarged detailed perspective 'view of a portion of one of the door posts showing a portion of one of the members of the door and the manner in which it perspective "View of the other of the door posts showing a portion of both members of the'door and the means employed for securposition posts showing the latch employed for or is retained in position against the Fig. 6 1s an-enlargeddetailed.

shaped channels

bars

cross strips

20 and 21 in this wise appear at the opposite ends of the door immediately to the sides of the ClOOI POSt'S. One end of each inemberisadapted to pass within the \(-

shaped channels

12 and 13, the other or free ends overlapping and being just clear of the doorposts. v

23 and 24 are bolts passing through the plates 14' and 15 across the ll-shaped channels and into the door posts. The bolts are located toward the upper end ot'the plates and serve the purpose of preventing the door from having any-upwardplay when in -This nisnooomplishedby cutting awa'yone of the upp mcorners of each mom- 8 is a vertical sectionher of the door, as at 25, so that the ends of the members. pass under and engage when in position, with the bolts.

26 and 27 are plates fastened to the inner member of the door near the bottom, their purpose being to keep the lower edge of the inner member of the door at the same level as the outer member of the door which rests on the door plate. 1

28 is abutton pivotally secured to the plate 15, such button being designed to retain the inner member of the door in the closed position when the car is empty. 29 are similar latches pivotally supported by pins 30 .which are carried by plates 31 securely fastened within a recess formed on the inner face of the door post 1. The door post is also recessed at 32 and 33, the recess 32 forming a housing for the latchwhen in the upper position, and the recess 33 allowing the latch to pass downwardly (in the direction of the arrow Fig. 8) to the alternate position, as shown by dotted lines. It

willbe noticed that the pins 30 passzthrough the latches somewhat to the side, of the center, and that the latches have their edges extending slightly beyond the plane of the door post. The purpose of this is to allow the latch to be readily thrown downwardly. v In order to better understand the opera-. tion of the door we will now describe the manner inwhich it is placed in position One end of the member 17 is placed within the channell'Z, and the opposite end of the member .ilS is passed within the channel 13, the members in this position overlapping for practically the full width of the door.- way. The latches 29 are thrown to. the position shown in dotted lines in Fig. 8, and in this position it is required that the cross brace 21 rest against the latches. If the car be filled with grain it is unnecessary to throw the button 28 to the position shown in Fig. 6, as the pressure of the grain prevents the inner member from swinging 1n-v wardly. When the car is unloaded or empty the button is required, as is obvious, to prevent the inner section from passing out of position. To open the door when the car is loaded it is only necessary to force the latches to their upper position. Immediately this is done the free end of the member 18 is pulled outwardly till it assumes the position shown in Fig. 4, when it can be readily removed by pulling itslongitudinally or pressing downwardly on the door sill. As soon as it is released the inner member is forced outwardly with the grain.

One of the characteristics of the novel features of the presentinvention lies in the fact that the free end of the outer overlapping section is held in position by the retaining latches 29 and. in this connection it will also be noted that the retaining latches are only to be considered as illustrative of ,pivotally interconnected with any form of releasable retaining means carried by'the' fixed posts and engaging the free end of the outer section.
