GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented Dec. 20, i910.

Application filed August 6, 1909. lSerial No. 511,604.

To all whom fit may concern.'

Be it known that l, Jumps Knot-1N, a citizen of the `United States, residing at Menomonie, in the county of Dunn and State. of l'isconsin, have invented certain new and useful Improvements in Grain-(hir Doors, of which the following is a specificaion, reference being had to the accompanying drawings.

This invention relates to improvements in grain ear doors-and especially with refer# ence to guide members for a gra-in car door, adapted to be applied to the door posts and serving to engage trunnions which project from opposite sides4 of the doen-and to guide such trnnnions so as to permit the door to be raised or lowered, and to also permit the door, when raised, to be swung' inwardly, and su ported from the car roof, as hereinafter fu ly described and claimed.

ln the accompanying drawingsl1`igure 1 is an interior elevation of a portion of one side of a car provided with a door, and a pair of my improved guide members for the door, the roof and floor of the car beingl shown in section. Fig. 2 is a` detail perspective view of one of my improved guide members. Fig. B is a transverse sectional view of the saine showing .the same applied to one of the door posts, and also showing the upper side of the door, and a trunnion of the door engaging the said guide member.

For the, purposes of this specication the side 5 of a grain car is shown provided with a doorway, and a vertically movable door 14 to close the lower portion of the doorway, the said door being shown provided with reinforcing* metal plates 15 at its sides, and also provided at its upper corners with oppositelyextending trunnions 16 having enlarged heads 1G', at their outer ends. The door is also shown provided on its inner side, near its lower edge and at its' center with a ring 17 pivotally connected thereto and for engagement with a hook 18 under the roof of the car. to support the inner end of the door when the latter is raised and swung inwardly under the car roof. ln accordance with my invention, I provide a pair of guide members'T, cach of Whiohf com rises a channeled portion to receive one of t ie door posts and providing side walls S), to engage opposite sides of the post. and an inner wall fl, comiectinp, the side walls 9 together, and to bear against the inner side` of the post. lhc said members are secured to theldoor posts by means of spikes 8 which are indicated in dotted lines in Fig. 1. Each guide member is also provided with an iiitegr'al tubular portion l0 which is disposed at the inner corner thereof at thelangle between two of the walls thereof, the said tubular portion forming a reinforce for the channeled' portion. The said tubular portion is provided at its upper end with a goose-neck 11, and is further provided with 'a guide slot 12, which extends from near the lower end of the tubular guide portion to the upper end of the goose-neck, that portion of the said slot in the goose-neck conforming to the curvature thereof. A securing plate 13 is formed integral with the goose-neck at the upper end of the latter, and has its central portion united thereto, the said securing plate extending beyond opposite sides of the goose-neck. and being applied to 'the car beam at the upper end of the post, and secured to the said beam as by means of the spikes, las shown in Fig. l.

It will be observed, upon reference to Fig. 2 that the upper end of the slot 12 is open. The said slots 12 of the guide members I"are on the opposing sides of said guide members, and are engaged by the trunnion 16 of the car door, the heads 16 of the trunnions operating in the tubular portions of the guide members. These trunnions are vertically movable in the slots 12, andas the door is forced upwardly, will follow the curvatureof the upper ends of the slots. Vhe-n the trunnions have been moved to the upper extremities of the slots 12, the door will close the upper half of the doorway. The door can be then swung inwardly and upwardly and secured in such position by causing its ring 17 to engage the hook 1 3, thus the said ring and hook coacting with the guide membelrs and the trunnions of the door to support the door in such lifted posi-j tion until the car has bleeneinj/)tied or filledl- Having thus described tlieinvention, what is claimed is: l.

The herein described guide member for the trunnion of a grain car door and for application to one of the'door posts, the said guide member comprising' a channeled portion to receive one of the door posts and providing webs or walls to-bcar aga-inst opposite sidcsiof and also against the inner side of the post, a tubular portion disposed at thel llt" c prebence goose-mec i; 2.1116
