l Application filed Anglia 1. i905. 'seal No, 272,268.
To @Zt whom it may cortan-mf` Y Y Be It known that I, Louis J. MIGHELL, a
citizen of the United States, residing at Lake- City, county of Calhoun, and State of Iowa, have invented a newand useful Improvement in Grain-Doors for Cars; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the' accompanying drawings, which form a part of this speciiication.
My invention has for its obj ect to provide a grain-door for cars that maybe readily applied to any construction of door or car, and which will be cheap and sim le in'construction, easily operated, and w ich will not be liable to become disarranged while inuse.
The invention consists in certain novel features of construction, as hereinafter shown and described, and specified in the claims.
In the accompanying drawings corresponding parts are denoted by like designating characters. v
Figure 1 is a side elevation from the exteriorof my improved door with the improvement applied. Fig. 2 is a sectional view showing the arrangement of the parts of the door when placed in its position in 'the car. Fig. 3 isa sectional view showing the position of the parts of the door when in a position to be removed from the car.
The sliding plates A are provided with a plurality of slots B, inclined at angles of forty-five degrees, and are loosely and movably secured within the door by means of bolts C. Said slots are of a length approximately three-fourths the width of the plate A and are cut in that part of said plates contained-and withdrawn'within a vertical recess at each end of the said door and are so retained in any position of the sliding plates. The downward inclination of the slots in each plate is toward the door-space and away from the casing, and when the plates are caused to slide downward the lateral movement thus obtained entirely withdraws each plate within the door, bringing the lower extremities of said plates slightly below the lower edge ofthe door, in which position said door exactly iits the opening In the doorcasing and the sliding plates A may be brought adjacent to the vertical slots D inl said casing. Under the action of gravity the weight'of the door actuates the sliding plates p A when their proj ectingends E are in contact with the floor of the car, causing them to Aslide vertically and laterally along their in- `clinedv slots, thus engaging the vertical slots D in the door-casing, completely closing the aperture between'door and casing, by which means the dooris locked by the sliding bars.
To remove the door, the above movements are' reversed, said doorbeing withdrawn in an upward direction. The ends of the sliding plates which are iiush with the upper edge of the door when locked come in contact with the upper end of the slots N, moving the plates A along the inclined slots B in a reverse direction to the movement oflocking, said inclined slots B bringing the sliding plates A to their first position, as shown in Fig. 3, the ends of said plates protruding slightly below the lower edge of the door, the lateral and vertical movement of the sliding plates being facilitated by the bevel, at M, on
the outer corner of said plates.l The upper portion of the door-space is supplied with a Ventilating door F, sliding in inclined grooves G, formed by two metallic cleats attached to the inside of the door-frame. ples II provide` means for suspending either door to hooks K on the upper part ofthe casing. Ordinary sliding bolts L are attached to the doorfurnishing a further means of securing said door to the casing and preventing disarrangement of the sliding plates by movements of the car while in transit.
I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is-
' 1. Agrain-door having extension-plates at its ends pslidably connected thereto by means which cause a relative vertical motion between said door and plates'to produce an inward lateral motion of said plates in combination with door-posts slotted to receive the projected portions of said plates, the upper ends of the slots providing shoulders against which the upper ends of said plates abut when the door is raised to cause said plates to recede.
2. Agrain-door having extension-plates at its ends slidably connected thereto by means which cause a relative vertical motion between said door and plates to produce an outward lateral motion ofl said plates in combination with door-posts slotted to receive the projected portions of said plates, said plates tending to depend below the edge of the door so that as the door is lowered to Stai IOO IlO
place they will meet the sill and be caused to v of said plates abut when the door is raised to cause said ng shoulders plates to recede; said plates tending to depend below the edge ofthe door so that as the door is lowered to place they will meet the I sill and be caused to rise and project laterally into the slots in the door-posts.
In testimony that I claim the foregoing as my own I have hereto aHiXed my signature in the presence of two witnesses.
L. J. MIGHELL.
