UNITED STATES PATENT OFFICE.

ROBERT D. STRYKER, OF HURON, OHIO.

GRAIN-DOOR.

Application led September 30, 1907.

To all whom it 1710/1/ concern.' i Be it known that I, ROBERT D. STRYKER, citizen of the United States, residing at Huron, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Grain-Doors, of which the following is a specification.

This invention comprehends vcertain new and useful improvements in grain doors for railway cars and for other uses, and the invention has for its object an improved construction of door of this character with an auxiliary or supplemental door hinged to the main door and designed, when opened, to form or produce an opening in the main door through which the grain is Vlirst allowed to run out, prior to enlarging the opening by the removal of the main door.

W'ith this and other objects in view as will more fully appear as the description proceeds the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and then point out the novel features in the appended claims. Y

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which:

Figure l is a rear view of a grain door embodying the improvements of my invention. Fig. 2 is a similar view with the upper section folded back. Figs. 3 and 4 are fragmentary front views illustrating the supplemental door in closed and partially open positions, respectively. Fig. 5 is a similar view with the supplemental door fully open. Fig. 6 is a transverse sectional view.

Corresponding' and like parts are referred to in the following description and indicated in vall the views of the drawing by the saine reference characters.

Referring' to the drawing, the numeral l designates the main jambs of a door way for a grain car or the like, and 2 the main grain door which is provided with the usual hinged section 2a adapted to fold back over the main section and arranged to be held in raised position by latches lat or similar fastenng devices secured to the jambs l. The main door 2 may be securely held in position by means of latches 2b of any desired construction secured to the floor of the car and engaging the main door at the lower corners thereof, so as to hold the main door against the jambs. The main door may also be pro- Speccation of Letters Patent.

Serial No. 395,282.

vided with any desired arrangement of parts so that it may be hung in the top of the car when not in use.

The main door 2 is provided, preferably near or at its bottom, with an opening of any desired size and proportions, said opening being closed by a supplemental door consisting of upper and lower hinged sections 3 and 3, preferably of equal size. The upper section 3 is hinged at its upper edge to the main door 2, and is mounted to swing' outwardly and upwardly, while the lower section 3lL is hinged to the upper section so that such lower section will swing inwardly and fold against the upper section when the supplemental door is o ened.

In order to secure y hold the door in closed position and at the same time to form a brace or reinforce for the said supplemental door, I provide a band 4 which is secured in a countersunk position to the section 3, preferably at the normally lower edge thereof and provided With a section at the back of the supplemental door, to secure the pivot bolt 4 securely in place, and a latch bar 5 of wood or metal is pivoted intermediate of its ends on the pivot bolt 4a flush with the supplemental 8 designates a pivoted hook which is secured to the main door above the supplemental door and which is designed for engagement with a screw eye or other loop 9 that in the present instance is secured to the latch bar 5 so as to hold the supplemental door in open position.

To protect the parts from Wear, I provide the latch bar 5 at its ends if the bar is made of wood with preferably metallic lates 10 designed to receive the wear of the eepers 6 and also provide the lower corners of the supplemental door with wear plates 11 designed to bear against the com lemental plates 12 which are secured to the ower corners of the supplemental doorway and that are designed to project slightly into the frame or doorway zio meeting edges of the sections 3 and 3a are preferably rabbeted so as vto `insu-re a tight joint when closed. Vertically extending battens 14 are attached to the rear face yof the main doorand project slightly into lthe supplemental doorway so as to form ambs ifor the supplemental door. The cleats 15 of the supplemental door are `(lesig-ned to bear against said jambs, lsaid bearing relation of the parts in connection ywith the beveled :edgesof the supplemental door and doorway insuring a ltight jointing and sealing of the parts when .the supplemental Vdoor is closed.

From the foregoing description in connection with the accompanying drawing it will `be seen that l have 4provided a very simple, durable and efficient construction of grain vdoor for grain cars and the like, which is supplied with a supplemental door so that a portion of the grain may be permitted to run out is claimed as new is:

A main grain door provided with anopening, a supplemental door adapted to close said opening and'consisting of an upper and a lower section, the uppersection being hinged at its upper edge to the main door yand 1arranged to swing outwardly therefrom and the lower section being hinged to `the upper section and adapted `to fold 4inwardly vupon the upper section and toiextend irri-closed position back of the extremity of the lower edge iof'the opening, and a latch bar pivoted intermediate of Iits ends on the supplemental doorat the meeting edges of the hinged sections thereof, the main door being kprovided with keepers for engagement by said latch bar.

In testimony whereof I affix my signature inpresence of two witnesses.
