GRAIN-CAR-DOOR CONSTRUCTION.

Specification of Letters Patent.

Patented Oct. 17, 1911.

/ Application filed November 12, 1910. Serial No. 592,046.

To all whom it may concern:

Be it known that I, HERBERT W. DREW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Car-Door Construction, of which the following is a specification.

This invention relates to improvements in grain car door construction and provides a construction whereby the door of a grain car may be easily maintained in a closed position or allowed to open at the will of the operator.

Referring to the drawings Figure 1 is a side elevation of a grain car showing the grain door in closed position. Fig. 2 is a transverse section along the line 2, 2 of Fig. 1. Fig. 8 is a partial sectional view along the same line as Fig. 2 and showing the looking mechanism in a position preparatory to opening the door. Fig. 1 is a partial sec tional view along the same line as Figs. 2 and 3 showing a part of the door in open position. Fig. 5 is a vertical sectional view through the car door showing the mechanism in locked position. Fig. 6 is a vertical sectional view along-the same line as Fig. 5 showing the door preparatory to the opening of the same. Fig. 7 is a vertical sectional view on the same line as Figs. 5 and 6 showing the door in an open position. Fig. 8 is a perspective of the details of the operative mechanism. Fig. 9 is a perspective showing the mechanism in locked position. Fig. 10 is a perspective showing the mechanism in an open position.

The grain door construction and general car construction is the same as that shown and claimed in my prior application No. 54:7,107, filed March 3, 1910.

The object of this invention is to provide in place of the operating mechanism for the grain door shown in that application another means of holding the grain door in locked closed position or to permit of .its being easily opened.

The same numerals refer to the same elements throughout the drawings.

The numeral 10 designates a grain door having a handle 10 to enable it to be readily opened and closed, manually if desired.

11 designates a T-shaped member with a vertical flange 11. i

12 designates an angular member to which the grain door is secured on either side. These angular members 12 have inwardly turned flanges 12 at their bottom extremity, these flanges 12 being inwardly turned on the bottom edge of the grain door 10. The locking mechanism' 13 is composed of the two members 13, 13 pivoted tothe door at 13 and to the flange ll at l3, respectively, and hinged to each other at 13. These members 13 and 13 have apertures 13 referred to hereinafter. The numeral 14 is used to designate the locking lever which is pivoted at one extremity to the side flange of the member 12 and carries at its other extremity a stud 15. The angular member 12 is pivoted at 17 to the flange member 11 and is spaced therefrom by means of a collar 16. Near thelower extremity of the locking lever 1 1 the latter is bent inwardly then downwardly as indicated at 18 for a purpose hereinafter described.

The members 13 and 18 are made of equal length and their axes of rotation 13* and 18 when the door is closed coincide so that when the door is in a closed position and the members 13, 13 lie together, as in dicated in Fig. 9, for example, they may rotate about a single axis.

In the operation of this device when the door is closed and the two members 13 and 13 come into juxtaposition preparatory to*' ing of the grain door 10. When it is desired to open the door the lever 14 is disengaged from the members 13, 13 and the latter are rotated into the position indicated by dotted lines in Fig. 6, whereupon the door will open either by reason of the weight of the inclosed grain or by means of a slight pull on the handle 10.

In reversing the operation when the door is open a slight tap at 13 where the locking members are hinged will throw them out of dead center and permit the door to be easily closed, whereupon it may be locked as shown in the drawings. This device furnishes a simple means of holding the door in locked "position and is easily operated. It is to be noted that the collar 16 spaces the members 11 and 12 far enough apart to allow the looking members to lie in a closed position and out of the way between the flange 11 and the inwardly turned flange of the member 12.

By fitting the side of the door opening with the T-beams 11 I obviate a very common difliculty in this class of cars, namely, the necessity of frequent coopering, which is not only comparatively costly, but necessitates the withdrawal of the car from active service. The T-beam being fastened to the side of the car, as shown and described, reinforces the side boards at their weakest point anttalthough they may bulge and warp this construction insures an even contact between the door and the side flange of the Tmember and prevents the escape of grain as well as insuring the easy operation of the door by preventing any jamming.

I claim:

1. In a car, a grain door, a flanged mem ber connected to one side of said door, a T-member connected to said car adjacent to said door, a pivotal connection between said first named member and said T-member, and a hinged locking device connected to each of said members whereby when said locking device is in one position said door is locked and when said locking device is in another position said door may be opened.

2. In a car, a grain door, a flanged member connected to said door, a T-member, said door being hingedly connected to said T-member by means of said flanged member, and a locking device, said locking device comprising check members, said check members being mutually pivoted at one extrenr ity and pivoted at their other extremities,

one to said T-member and one to said flanged member, said last named pivotal member, said last named pivotal connections being adjacent when said door is in closed position, and a locking lever adapted to engage said check members and hold them in a locked position when said door is closed.

4. In a car, a grain door, a flanged member connected to said door, a T-member, said door being hingedly connected to said T- member by means of said flanged member, a
