UNITED STATES PATENT OFFICE.
(LIFTON I). PETTIS, OF TERRE IIAUTE, INDIANA.
GRAIN-CAR DOOR.
SPECIFICATION forming part of Letters Patent No. 415,468, dated November 19, 1889.
Application filed February 16, 1889. Serial No. 390,094. (No model.)
To all whom it may concern.-
Be it known that I, CLIFTON D. PETTIS, of Terre Haute, in the county of Yigo and State of Indiana, have invented a new and Improved Grainar Door, of which the following is a full, clear, and exact description.
This invention relates to grain-car doors, the object of the invention being to provide an exceedingly simple, cheap, and durable door, and one which, when not in use, may be compactly'stowed in the upper portion of the car just beneath the carlings.
To the ends named the invention consists of novel constructions, arrangements, and combinat-ions, to be hereinafter more fully described, and specifically pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a partof this specification,
in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is an inner face view of my improved grain-car door, the carbeing shown in central longitudinal section. Fig. 2 is a crosssectional view taken on line or .r of Fig. 1. Fig. l is a face view of the wear-plate or hooksocket, which is connected to the outer face of the door, near the upper edge thereof. Fig. 1 is an edge view of the socket shown in Fig. 3. Fig. 5 is a plan view of one of the forgings by means of which connect-ion between the door audits supporting hooks or rods is established. Fig. l) is a plan view of one of the toes employed to hold the lower edge of the door close against the door-posts, and Fig. 7 is a detail perspective view.
In the drawings, 10 represents a door, to the inner face of which there are bolted forgings 11, which constitute eyes adapted to receive rods 12, formed with open hooks 13 at their lower ends, said rods being connected to eyebolts 1;, as shown. At the lower corners and upon the inner face of the door I secure wearplates 15, which, when the door is in the po sition shown in the drawings, bear against toes 16, that are screwed to the car-floor, the toes serving to hold the lower edge of the door against the door-posts, the upper edge of the door being held to place by hooks 17, which engage eyes 18, carried by the door, the hooks being held from displacement by gravity keepers 19, that are pivotally mounted above the hooks and arranged to bear upon the upper edge of said hooks, as shown in Fig. 2.
In a position proper to receive the upper outer edge of the door I mount a gravity-hook 20, said hook being suspended from one of the carlings, and upon the inner face of the door I secure a wear-plate 21, which is formed with a socket 22, so placed as to be entered by the hook when the door is moved, as will be now set forth.
To clear the door 10 when the car is filled with grain, the hooks 17 are thrown from engagement wit-h their eyes 18 and the door is slid upward from the car-floor upon the rods 12, the open hooks 13 permitting the rods to pass through the forgings, thus permitting the grain to flow outward beneath the lower edge of the door, and after sufficient grain has so flowed outward to permit of the swinging of the door the door is swung upward, so that its lower edge travels, as indicated by the curved line (1, until said lower edge strikes the eyes 14:. Then the rods 12, and with them the door 10, are moved upward until the hook 20 enters the socket 22 of the wear-plate 21, the hook being so formed that an accidental disengagement of the hook is almost impossible.
To facilitate the upward movement of the door, I provide it with a hand-plate secured to the lower outer side of the door, said handplate being recessed, as indicated at I) in Fig. 1.
Having thus described my invention, I claim as new and desire to secure by Letters Patent In a grain-car door, the combination, with the body of a car provided with the toes 16 on the floor, of the door 10, provided with the forgings 11, and the socketed Wear-plate 21 22, secured to the upper inner face of the door, the rods 12, pivoted at their upper ends to the inside of the car-body and having the open hooks 13 on their lower ends, and the gravity hooks 20, substantially as herein shown and described.
CLIFTON D. PE'lTIS.
