JAKOB HEUCHERT, OF WINNIPEG, MANITOBA, CANADA, ASSIGNOR OF NINE-TENTHS TO MARGARET MULLALY,

OF MVINNIPEG, CANADA.

GRAIN-CAR DOOR.

To all whom it may concern.'

Be it known that I, Janes HnUoHnn'r, of the city of Vinnipeg, in the Province oit Manitoba7 Canada, have invented certain new and use't'ul Improvements in Grain- Car Doors, of which the following` is the specification.

My invention relates to grain car doors and the object of the invention is to provide a door which can be quickly opened to release grain7 coal, or other such like substance from a car and which when opened can he readily raised and suspended t'roni the roof of the car.

A further object o'l.f the invention is to provide a strongly reinforced door which will not allow leakage oit grain l'ronl the car when closed and which has no tendency to rise from the closed position.

The invention consists essentially in a door havingl an outer cross rod secured thereto upon which it is outwardly swingable, vertically directed channel irons secured to the door posts and .receiving the ends of the rod, channel iron bars secured to the opposing face o't` the door post and engageable with the inner side oit the door, pivotally supported angle iron bars located within the door posts and engageablc with the outer face o1. the door, nieans 't'or turning the channel iron ineinbers in unison, nicaus for suspending the door 'troni the roof of the car, and ineans for locking the door in the closed position, the parts being arranged and constructed as hereinafter inore par ticularly described.

F igure 1 is an exterior View oit' a portion of a car with .my door applied. Fig. 2 is an interior View as in Fig. 1. Fig. is a vertical sectional view through the door the section heilig taken in the plane denoted by the line X X, Fig. 1. F ig. 1t is a plan view of the mechanism utilized tor closing and opening the channel iron bars, the parts being shown as they appear when the door is closed. Fig. 5 is a similar view ot' the above parts as they appear when the door is tree to open. Fig. is an enlarged vertical sectional viewthrough one ot' the door posts Specification of Letters Patent.

showing the nianncr in which the door is held in the closed position.

In the drawings like characters ot' reference indicate corresponding parts in each figure.

l and 2 represent the door posts of a car, 3 the door sill, and et. the lintel or upper cross beanr, such parts bounding the doorway opening 5.

G are the inner and 7 the outer face boards of the car appearing to either side of the doorway opening.

S is the rootl ot the car carried by the bealns 9 in the usual manner.

10 is the car floor.

The door sill 3 is cut away at the doorway opening and a plate l1 is inserted therein having an upwardly directed flange 11 which bears against the door. It will be understood that the body ol the plate is slightly below the level o1 the tloor.

12 is the car door which is o1. the height usually enll'iloycd for carrying the various grains and ot' a length which will allow it to 'pass between the door posts. The door has a cross bar 13 secured to its upper edge to which I have .fastened two eye bars 11 carrying a cross rod 15 having the ends thereof extending to the side and behind the post where they are received and carried by vertically directed channel irons 1G secured to the posts. The channel irons have their upper and lower ends closed and coinniunicate at their upper ends with notches 1G formed in the door posts the purpose ol which will shortly be apparent. then the door is in the closed position the rod 15 rests on the lower closed end o'l the channel irons and the lower edge or bottoni of the .door bears against the flange 11, ol the plate 11.

17 are vertically directed channel irons firmly secured to the opposing `tace o'l the door posts and bearing against the inner .face ot' the door when in its closed position.

1S and 19 are angle iron bars located within recesses 20 formed in the door post-s said bars having shanks 21 extending there from the upper ones of which are pivotally secured within the door posts at the upper end of the recesses 2O which it will be understood only extend upwardly a slight distance above the upper edge of the door. The lower or downwardly extending Shanks of those 21 pass through suitable openings 22 formed in the door sill and are supported by brackets 23 carried by the vcross beams 241 of the car.

25 are bearing plates secured to the under side of a car and through which pass the downwardly extending` Shanks 21.

26 and 27 are arms secured to the lower ot the Shanks 21 by adjusting nuts 28'and appearing on the shanks between the bearing plates 25 and the brackets 23. The arms on the Shanks extend in opposite directions and have short links 29 secured thereto which receive the threaded end ot a rod 30.

31 is a strap secured to the under Side ot the car and passing Linder the rod 30 such being provided to hold the rod in place and to prevent it from sagging.

The arm 26 has an extending portion 26 to which is hingedly secured a lever 32 by which the arms are turned. The lever operates over the adjoining edge of the bracket 23 which is notched at 23 to receive the lever and hold it in a set position. An opening 33 is provided in the extending portion of the arm 26 for the insertion of a pin or lock whereby the lever is held in the lower position until the pin or lock is removed.

311 is a hook pivotally Secured to the beam 9 of the car and adapted to receive the lower edge of lthe door when it is raised to the roof of the car.

It is to be noticed that one of the arms of each of the irons 18 and 19 is wider than the other and that the narrower arms swing within the notches 20 while the wider ones are adapted to lie iiush with the tace' of the door posts when turned and be received within grooves 20 continuo-us with the notches. It is also to be noticed that the arms of the angle irons 18 and 19 are cut away somewhat above the floor level of the car the reason for this being that it makes it easier for them to be put in position when a car is being equipped with my door.

The lower shanks are inserted within the openings 22 and passed downwardly as far as possible so as to admit the upper shanks within the notches 20. When the angle irons are raised the upper Shanks pass into the openings or bearings provided for them at the upper end of the notches and they are held in this position by the tightening of the adjusting screws 28 on the lower Shanks.

35 are pins or lugs extending outwardly from the face of the door such lugs being provided to enter complementary openings 3G provided in the wider arms of the angle irons 18 and 19.

In order to more clearly understand my invention I will now describe its operation assuming the door closed and the car filled with grain. To open it is only necessary to release the locking means supplied in the opening 33 and raise the lever 32 to the horizontal position then swing it to the position shown in Fig. 5. This motion causes the angle irons 18 and 19 to turn until the wider arms are flush with the faces of the door post at which instant the door swings outwardly on the rod due to the outward pressure of the grain. The door is then raised and the ends of the rod are broughtinto the notches 16 at which time the door is swung inwardly till the lower edge is retained by the hook 811 in which position it is suspended.

I wish to draw particular attention to the angle irons 17 and to the plate 11 as these are of great value in preventing grain from leaking from the car when the door is closed.

The angle iron bars 18 and 19 not only serve to prevent the door from swinging outwardly but also serve to hold the door tightly against the angle irons and the flange 11 so that leakage is practically impossible.

It may be found desirable in certain instances to release the grain slowly from the car without allowing the door to swing outwardly. In order to accomplish this I have provided a lever 37 having a cam Shaped head 37 such lever being pivotally secured to the outside of the doo-r by a pin 38. 39 is a further pin engaging with the lever in the normal position and preventing it from passing downwardly below the lower edge of the door. A notch 322 is provided in one of the brackets 23 which will allow the angle iron bars to be turned slightly by the lever and held in such position thereby releasing the door sutiiciently to allow it to be raised by means of the lever 37. By turning the lever 37 to the alternative position to that shown in Fig. 1 it will be seen that the door will be raised by the action of the cam head against the plate 11.

`What I claim as my invention is:

In a device of the class described, the combination with the door posts of a car having vertically directed notches therein, of an outwardly swingable doo-r adapted to pass between the door posts, a set of vertically directed angle iron bars located within the notches and having upwardly and downward extending Shanks, the upper Shanks passing into suitable formed in the door posts, and the lower Shanks beneath the ear through Suitable openings formed in the Sill, brackets earried at the nnder Side of the ear receiving the extending ends Vof the lower Shanks, ad jnstable arms Secured to the latter Shanks and extending in different directions, a rod Connecting Said arms together', bearing plates Secured to the under Side of the ear through which the lower Shanks pass, and

bearings l a lover hingedly Secured to one of the arms and adapted to operate over notches provided in the adjoiningl bracket to hold the angle irons in a set position, as and for the 15 purpose Speeifieifl.

Signed at Winnipeg, in the Province of Manitoba, thiS 25th day of August 1909.
