ANDREW L. ALVE'Z, OF KANSAS CITY, KANSAS.

GRAIN-GAB DOOR.

Application filed April 13,

To all whom it may concern:

Be it known that 1, ANDREW L. ALVEY, a citizen of the United States, residing at Kansas City, in the county of lVyandotte and State of Kansas, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is a specification.

My invention relates to improvements in grain car doors. 1

The object of my invention is to provide a grain car door which may be easily and se-- curely locked in the closed position, and which may be quickly and easily opened when the car is loaded with grain.

A further object of my invention is to provide an outwardly swinging hinged door construction in which, when the car is loaded with grain and the door closed, the hinges will not be subjected to strain due to grain pressure on the door.

Another novel feature of my invention consists in the sealing means employed for closing the joints around the door when closed, to prevent the escape of grain.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate one form of my invention, Figure 1 is an outside elevation of a portion of a car provided with my improved construction, the doors being shown in the locked positions. Fig. 2 is a horizontal section on the line aZ) of Fig. 1. In this view the doors are shown in dotted lines in the open position. Fig. 3 is a vertical section on the line c-(Z of Fig. 1. Fig. 1 is an inside view of the doors in the closed position, the view being a vertical section on the line c-f of Fig. 3, a portion of the door lintel being broken away.

Similar reference characters designate similar parts.

1 designates the body of an ordinary grain car having the usual door jambs 2, a door lintel 3, and a door sill 4t.

5 and 6 designate respectively two outwardly opening doors pivoted respectively to the jambs 2 by hinges 7, which have vertical pintles S, which serve as the vertical axes of the doors 5 and 6. The door 6 is preferably provided with a longitudinal flange 9, which, when the doors are closed overlaps the door 5.

The doors 5 and 6 are provided with portions 10 which, when the doors are closed,

as shown in solid lines in Fig. 2, overlap and rest against the inner sides of the jambs 2 respectively. By means of this construc tion, when the car is loaded with grain and the doors are closed, the overlapping portions 10 bear against the jambs 2, thereby relieving the hinges T from strain due to grain pressure on the doors.

In order that the grain pressure upon the portions 10 of the doors 5 and 6 may not be suiiicient to interfere with the easy opening of the doors, I provide guards which overlap the inner sides of the portions 10, when the doors are closed. Preferably these guards comprise vertical plates 11 respectively secured to the inner sides of the jambs 2 and having vertical arcuate portions 12 which, when the doors are closed, overlap or extend over the adjacent portions 10 respectively. Said arcuate port-ions 12 are preferably vertical longitudinal flanges arcuate in cross section, the centers of the arcs coinciding respectively with the axial centers of the pintles 8 which are the axes of the doors 5 and 6. The arcuate flanges 12 are disposed so as to just clear the adjacent Vertical edges of the doors 5 and 6 when the doors are swung to and fro, thus preventing grain from passing between the edges of the doors and the arcuate flanges 12 at the time the doors are swung from the closed toward the open position.

The door sill 4': is provided at its inner edge with an upwardly extending longitudinal flange 13 against the outer side of which the doors 5 and 6 are adapted to bear when the doors are closed. The flange 13 is preferably provided with an inwardly and downwardly inclined extension 14L which reaches from the upper edge of the flange 13 to the floor of the car body 1, thereby permitting the easy removal of the grain lying on the floor and against the extension 1 1-.

The portions 10 of the doors 5 and 6 are notched at 15, to permit the portions 10 passing over the flange 13 when the doors are swung.

Suitable releasable means may be provided for locking the doors 5 and 6 in the closed positions. For this purpose 1 preferably provide the following described locking mechanism.

A rock bar 16 is pivoted by means of a rivet 17 to the door 6, the rivet extending through said door at a point adjacent to the flange 9 and near the' longitudinal center of mild said door. To one end of the rock bar it) is )ivoted by a rivet 18 the lower end of an upwardly extending bar 1.9 vhich is slid ably mounted in a suitable guide 20 secured to the outer side of the door (3 adjacent to the upper edge thereof. The upper end of the bar 19 is adapted to enter a vertical. hole 21. provided in the under side of the lintel To the other end of the rock har 16 is pivoted by a rivet 29. the upper end of a down- 'ardl extending bar 23, which is slidahly mounted in. a guide 24. secured to the outer side ot the door 3 near he lower edge thereoil. The lower end of the har r23 le adapted to enter a. vertical hole providern the door sill. 4:. when the rock bar 16 is vertirally disposed, as shown in solid lines in Fig. 1, the bars 15) and 23 will he respectively disposed in the holes 21 and il hen the rock bar is horizontally disposed, as shown in dotted line. in Fig. 1, the hers 1*.) and will be withdrawn from the holes 21 and 25. To swing the rock har 16 to and from the locked. position a lever 26 is pivoted. one end to the rock bar 16, the pivot or the lever heinodii'sposcd horizontally when the rock bar is vertically disposed. The lever 26 is provided, prcterahly with a longitudinal slot 27, adapted to receive therethrough, when the rock her and bar 523 are vertically disposed. a staple 28 secured to the outer side of the hair 22% and. adapted to receive a sealing device 25 'for securing the lever in locked engn moot with the staple 28.

A. similar locking mechanism may be pro vided for locking the door if desired, although in some cases the locl ring mechanism which has just been desi. 'ihcd, will be sutlicient tor the purpose oi. locking both doors in the closed position. in the drawings, l have shown two guides 20 and secured to ti 0 door 5, and bars 19 and 23 respectively slidahly mounted in said guides and pivotallv connectedv to opposite ends of a rock her 15. which pivoted to the door 5, the rock her having secured to it a lever 26 having:' a. slot 2'? tor receiving a staple 28 secured to the bar 23.

l i hen it is desired to open the doors 5 end. (i. the scaling: devices 2!) are removed from the staples after which the levers 526 are swung outwardly until the levers are clear ot the staples 28, after which the levers and rock bars 16 are swungto the horizontal position. thcrel'iy withd awingz the b: .1 19 out 93 from the holes 21 a d The doors being thu released, will he swung to the open position, shown in Fig. 9 in dotted lines. reason of tire guard flanges 12, the grain will not offer much resistance to the opening movement of the doors.
