NETE@ rasant WILLIAM DAHLEN, OF DULUTH, MINNESOTA.

Gnarls noon.

Application filed February 21, 1922. Serial No. 538,206.

To all 'whom t may concern:

Be it known that I, WILLIAM DAHLEN,

a citizen of the United States, residing at Duluth, in the county of St. Louis and State e of Minnesota, have invented certain new and useful improvements in Grain Doors, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to railroad car doors and has special reference to what is commonly known as grain doors for cars.

' The principal object is to provide means whereby a practical door of this type may be is readily produced when necessary from common lumber, with the least amount of effort and skill.

Another object is to provide 'means where by such a door may be readily reinforced 2e when desired.

Still another object is to provide convenient means for initially opening the door when the car `upon which it is employed is loaded.

Other objects and advantages will appear in the further description of the invention.

Referring to the accompanying drawing forming part of this application and in which like reference characters indicate like pal'tS:

Figure 1 is an inside elevation of one ernbodiment of the improved door parts being broken away;

Figure 2 is a horizontal vertical sectional view on the line 2 2, Figure l;

Figure 3 is an outside elevation of the door showing the outer opening board partly raised;

FigureiiL is a central vertical section on .te the line 4-4 Figure l; and

Figure 5 is a perspective view of one of the door boards. j Y

1 and 2 represent the rectangularly shaped door posts as commonly found upon railroad es cars, between which is formed the usual door opening 3. i

About the innermost opposite corners of the two door posts l and 2 is installed a generally angularly shaped metal facing vl eo the same preferably extending the full width of the face of the posts within the door opening, though it is preferably not of the full width of the posts upon the interiory of the car. These metal facings extend the full' height of the posts and are securely fastened thereto in any desired manner as for example by large screws 5 and are upon their lowermost ends turned at right angles as at 6 forming foot pieces which may be securely bolted or otherwise fastened to the floor of the car, thus forming additional strengthening members for the posts, this being for the purpose of compensating for any weakening ofthe posts that might occur from the application of the improved door.

rlhe edge portions of these angle irons Il are projected inwardly as at 7 at right angles to the inner face thereof and then bent again at right angles towards the door opening as at 8 forming vertical channels longitudinally of the edges thereof, and which channels terminate some considerable distance from the floor of the car approximately the width of one of the boards or members of which the door is composed. At such lower terminations of these channels, bottoms therefor are provided as at 9 by there being securely fastened to the inner face of the angle iron a Z-bar clip 10, clearly shown in Figure 4c of the drawing. These clips which form the lower terminal of the channels provide supports for the door boards as they are placed within the channels and prevent same from extending below lsuch terminations. The door boards 11 are of the proper length to fit within the channels transverse the door opening and are preferably somewhat rounded upon their ends so that either end may be lifted as by a bar or the like from beneath and all of the boards forming the door thus conveniently dislodged when itis desired to open n 4.
