panying drawings.

a device of this kind,

'very simple, eflicient and overlying the opposite side edges or This invention relates to an improved grain door for use in connection with grain cars, trucks and the like, to provide a device of this kind, which is practical in construction and capable of being cheaply made and sold and applied to a car at a reasonable profit.

Another object consists in the provision of wherein the grain door is slidable into a closed position, in combination with a single loop lever adapted for moving the door into and out of closed position and adapted to be engaged by a'latching member, for holding the door,

locked.

Still another object consists in the provision of guides, with which the door engages, in combination with inclined flanges flanges of the door (which are beveled or inclined correspondingly to the flanges of the guides) so that the door may wedge into locked position.

A further object embodies a flange across the lower portion of the dooropening ex tending from one overlying flange of one of the guides to the opposite flange of the other guide, to act as means to prevent escape of the grain when the door is closed.

While the design and construction at present illustrated and set forth is deemed preferable, and it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and :he right to these changes is claimed, provided they are comprehended within the :cope of what is claimed. 7

The invention comprises further features LDCl combination of parts, as will be herenafter set forth, shown in the drawings and laimed.

and an object is Patented In the drawings Figure l is a view in side elevation of a portion of a grain car, showing the improved grain door as applied thereto, showing thedoor in closed position,

Nov. 9, 1920.

2 is a view in side elevation of the side of a truck body, door as applied, and showing the door in an open position,

1 133 is a vertical sectional view on line 8-3 ofF 1g. 1, showing the door closed and locked, Fig. el- 18 a sectional Fig. 2, showing view on line 4:l of the door open, a portion of the single actuator being engaged by the upper part of the door, so as to act to open the door a substantial distance, and

*ig. 5 is a detail perspective view of the lower end of one of the vertical side angle irons 3 showing how the inclined bent por tion 8 is formed. y

Referring more especially to the drawings, 1 designates a portion of a grain car which is provided with a grain door open-i ing 2. Extending vertically of the sideof the car and adjacent the door opening are angle members 3, which are arranged in order to form guides for the grain door. An angle iron 4 isarranged 111 a horizontal position and is secured to the at 5 so that oneof the side of the car as flanges thereof will to deflect the rain door.

The lower portions of the vertical angle irons 3 are bent upon themselves as shown shed,

act as a cover or at 6 and in order to accomplish this thelat i 90 eral flanges 7 of the guide angle irons are cut as shown at 8, thereby permitting the lateral flanges of those portions of, the bent to overlie or over guides which are lap the lateral flanges of the vertical fixed portions of the angle irons. It will be noted that the bent portions 9 of the side angle irons are inclined, and in order to attain this result, the lateral flanges of the fixed portions of the vertical guides are beveled off or inclined wvhere they are cut at? 8, whereby the bent portions 9 may engage therewith. The lateral flanges of the best portions 9 are bolted or riveted or otherwise secured at 11 to the lateral flanges of showing the improved side jambs of the and the like from the 'metal plate 26 are spaced from .door will be moved the fixed guides in order to insure a rigid construction and so that the bent portions 9 may act as abutment means, with which parts of the grain wedge, when the door is closed.

The protecting angle iron is secured to the lower part of the ear, and overlies thelower portion of the door opening and the in clined bent portions 9, in order to insure a rigid construction. T his protecting angle iron 12 is secured at-13 to the car, and the flange 1% is disposed or bent in order to'be engaged by the door to insure a firm position of the door when closed. The vertical angle irons 3 are secured at 15 to the side of the car.

A door actuating member or lever loop 16 is provided and it is constructed from a single length of rod material bent upon itself to, form the loop 17, the side arms of which have lateralparts 18. Beyond the lateral parts 18, the arms of the'loop are extended in parallelism, and in alinement with the arms of the loop as shown at 19. T heends ofthe portions 19 are bent laterally to provide the trunnions 20, which are fulcrumed in bearings 21 of the lateral flanges of the vertical guides or angle irons 3so that the lever loop be moved pivot-ally for the purpose of opening and closing the door. A grain door 22 is provided, and this door comprises .a frame having side angle pieces 23 and transverse pieces 24: and 23, which are riveted together and to which a sheet metal plate 26 is riveted, as shown T he vertical side edges of this sheet the lateral flanges of the frame of the door, a distance so that the plate may engage between the edges of the flanges of the bent portions 9 to assist in reinforcing the door. In other words, the sheet metal plate 26 is of a width sufficient to set between the edges of the flanges of the bent portions 9. Metallic loops27 are secured at 28 to the door and these loops are in turn pivotally mounted on the lateral parts 18 of theloop lever so that when the lever is moved upwardly, the from its guides, and

door may be withdrawn when the loop is moved downwardly, the l to a closed position, and when dHlOVQiltO a closed position, the bev eled edges 29 of the lateral flanges; of the sideangle irons of the door will wedge into contact with the flanges of the bent portions 9, and insure holding the doorin a rigid closed position, and be lower part of the sheet metal plate 26 will also wedge in contact with the flange 14: of the protecting angle strip.

Pivoted on the metal plate 26 as at 30 is a rotatable button or plate 31 provided with an arm 32. The armr32 is designed to overlie the lever loop, when swung to a downdoor are designed to ward position and the door closed in order to hold the door in a closed position and in a wedged contact with the bent portions 9 and the flange 1 1. Men it is desired to open the door it will be noted that the button may be rotated on its pivot in order. to move the arm 32 from a position over the lever loop. in which case the lever is free to be swung upwardly on its fulcrum. it will be noted that the portions of the arms of the lever loop between the trunnions 20 and the bent portions 18 will be so disposed with relation to the upper edge of the the lever is moved on its fulcrum for the purpose of opening the door, the upper edge of the door will contact with the portions of the arms between the'parts 18 and the trunnions 21) so that upon further movement of the lever loop, the door may be swung entirely openin an upward direction.

When the door is so opened it will assume a position at right angles to the lever loop. It willfbe observed that the door may be opened as above stated and. thentheloop maybe closed against the outer facelof, the door and lockedin such a position so that the door may swing outwardly and upwardly with the lever 'loop,'in fact the two will move together as one body. rangement and operation of the door is only attained when the lower .edge of the door has been disengaged from the bent portions 9 of the lower ends of the angle irons 3 When the door is so used, it will swing against the outer portions of the bent portions 9 and may be tilted outwardly .in order to permit the discharge of grain and to permit access to the interior of the car through the grain door opening.
