Specification of Letters Patent.

Patented Sept. 1, 1914,

Application filed. April 7, 1913. Serial n5. 759,530.

To all whom it may concern:

Be it known that I, BRYAN J. ONEILL, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Grain-Doors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in car doors, particularly pertaining to a door for freight cars and adapted particularly as a grain door for both inside and outside use.

One of the objects of the invention is to furnish a grain door that can be readily adapted for use either inside the doorway or on the outside of the car so that it will be grain tight in either of those positions.

Another object is to furnish a door that will close the entire door-way from bottom to top and at the same time one that will have no parts that can fall upon and thus be dangerous to persons working about the car.

Another object is to furnish a door that will be practically indestructible in that those working about the car cannot damage the door in any way.

Another object of the invention is to provide a tilting or pivoted door section and a sliding door section the former operating the latter in its opening or closing movements.

Another object is to provide a metal grain door of great strength, and means for holding all of its four edges when closed and covering the door opening, in order to support the weight of the grain against it, and in order to provide an absolutely grain tight job particularlywhen the door is used outside of the car.

Another object is to "improve upon the structure of the door patented to me and J. Conners'adm. of M. Voorhees, decd on the 23rd day of August 1910, #968,073.

In order to make my invention thoroughly understood I have furnished the accompanying drawing, in which,

Figure 1 is an elevation of a portion of the outside wall of the car showing my improved door 111 connection w th the same;

Fig. 2 is a similar illustration showing the door partially open. Fig. 3 is a horizontal section of the wall of the car and the door shown on the outer side of said wall. Fig. 4 is an elevation of the edge of the door as seen in the direction of the dart in Fig. 3. Flg. 5 shows a part of the car and its door opening in perspective. Fig. '6 is a vertical section of the door somewhat enlarged over that shown in the other figures. Figs. 7, 8 and 9 are horizontal sections of portions of the door and the wall of the car taken re spectively on lines w 00, y 3 z 2, Fig. 1.

A is the wall of the car and B is the usual door opening. 'Above the door opening is a track C the form of which is preferably that shown in Fig. 6 or what is known as the Z type of track which furnishes a depending flange D behind which the upper edge of a main door section represented at E is de signed to lie. Said main door section is supported upon the track by means of hangers F provided with rollers G. The said door section extends from the top of the opening 13 down to within a comparatively short distance from the floor, covering practical-ly three fourths of the door opening as a preference, but the amount of door opening covered is merely optional except, as will be understood later, an opening must be left below it. The door section E is provided with a hinged door section F which may be secured in its closed position by any suitable fastening means, the car being loaded through the opening covered by said door section from any usual grain spout. Inside the section E the hangersF are extended into depending strap portions F which, in the present instance, lie on the inner side of said section, see Figs. 3 and 6. Inside the lower portion of said section and lying upon the strap portions so as to be spaced from the former in a small section G" the relation of the latter and the section E being clearly shown in Fig. 3 said section G, if desired, being extended somewhat beopening and constituting a j amb. This bar i H prevents the door from swinging outward but if desired the entire edge of the door section E may also pass behind said bar.

J is a lower door section pivoted at its lower edge at one end upon the wall of the car at one corner of the door opening. K is a stud extending through the wall of the car and forming the pivot for the said lower section J. A worm-wheel L is secured relatively to the said door section in any suitale manner to rotate on said stud. The inner end of the stud maybe secured relatively to the wall in any suitable manner and forms a solid support for the parts described. However, if desired, the said stud may constitute a shaft which may be rotatably mounted in the wall in any suitable manner if desired, the door section J and the worm wheel being afliXed thereto.

M is a worm suitably journaled on the side of the car and having engagement with the worm-wheel, the same having a suitably extending shaft N by which rotation may be imparted to it.

0 is a Z-bar secured to the side of the car in a horizontal position below the door way and into this and upon it the lower door section J is adapted to rest as shown in Fig. 6 while the upper edge of the section J lies between the parts E and G. The upper edge and one of the side edges of the door section E when the latter is closed are held by the track and the Z-bar H and resist the great pressure of grain from within. The lower edge of the pivoted section J as -well as its free end are also likewise held by the Z-bars O and H respectively. I shall now describe the manner in which the remaining or fourth edge of the door section E its section G and the pivoted section J are provided with means having the same end in vielylv of making the door practically grain tig t.

As shown in Figs. 3, 5, 7, 8 and 9 a Z-bar P is secured to the side of the car at the right hand side of the door opening B and which faces in the same direction as the 2- bar H previously described. By a study of Fig. 7 which is a section of the door portion E on line w m Fig. 4, it will be seen that a U-shaped strip Q, is secured upon the hanger strap F. This extends down as far as the upper edge of the lower section G. Again, in Fig. 8, which is a section on y Fig. 4, it is observed that the section G which, as explained, is secured upon the straps F, has a recurved edge R which is of the same form as the part Q described. In Fig. 9 which is a section on line 2 2, Fig. 4, there is shown a U-shaped strip S secured to the lower door section J in the same manner as the strip S secured to the lower door section in the same manner as the strip Q and in Fig. 4 it will be observed that all of the parts Q, R, S, lie above one another in the closed position of the two door sections E and the pivoted section J. These said parts Q R S engage behind the extending flange of the Z-bar P. This structure provides for securing the right hand edge Between the door sections E and G are two stops T U spaced from one another the purpose of which will now appear.

In the operation of the door the lower section J which lies below and partially within the space between the door section E and its section G as explained, when raised slides up into said space and as shown in Fig. -1 it meets one of the stops T. A continued movement results in shifting the main door section E to the right upon the track C due to contact with said stop T. After the section J has reached the vertical position or has passed slightly beyond that position the main door can be pushed by hand to its full open position. In lowering the pivoted section to close the door it engages the other stop U and this results in moving the main door section upon its track and if desired the attendant may assist in the shifting movement of the door the pivoted section pass ing down to its place in the Z-bar 0 after the stop U has been moved away from it. The track C holds the upper edge of the door in position so that it cannot push outward as explained and thus it readily guides the edge of the door behind the Z-bar H aided also by the fact that the lower pivoted section which has no lateral movement on the member K also assists in properly guiding the door behind said bar H and for the same reason the Z-bar P is engaged by the parts Q R S. A slight raising of the section J permits the grain to pass out through the opening left by it to remove the pressure from the entire door so that said door may be swung back with but little effort.

In order to close the entire door opening I and still have the advantage of a powerful form of lifting apparatus I have employed the easily lifted pivoted door which covers the lower part of the opening, together with the sliding door section which closes the entire upper portion of the opening. The advantage of the present structure therefore is to enable me to cover the entire door opening whether inside or outside the car together with means for holding a door at all four of its edges as well as preventing loss of grain.

One of the advantages of my door is that besides being a grain door it furnishes a door for all other purposes and is what may be termed an all service door so that while particularly adaptable for grain it is likewise usable for all other purposes.

section J v Various changes may be made in the structure throughout since I do not wish to confine myself to the exact arrangement shown.

Having described my invention, I claim 1. A grain door comprisinga lower door section pivoted at the lower corner of the door opening, and an upper horizontally movable section engaged and moved by said lower section.

2. A grain door comprising a lower door section pivoted at the lower corner o1 the door opening and adapted to tilt in a plane parallel to the side of the car, an upper door section adapted to move in a horizontal direction parallel to the side of the car and engaged and moved by the pivoted section.

3. A grain door comprising a lower door section pivoted at one of the lower corners adjacent one of the lower corners of the door opening and adapted to tilt on its pivot parallel to the side of the car, an upper door section horizontally movable parallel to the side of the car, and a part on said upper door section engaged by the lower door section after a predetermined upward movement of said lower door section.

4;. A grain door comprising a lower door section pivoted near the floor of the car at one side of the door opening and adapted to tilt parallel to the side of the car, an upper suspended door section also movable parallel to the side of the car and engaged and moved by the said lower door section, and means to operate the latter.

5. A grain door comprising a lower door section pivoted near the floor of the car at one side of the door opening and adapted to tilt parallel to the side of the car, an upper suspended door section also movable parallel to the side of the car and engaged and moved by the said lower door section, a member secured relative to the door, and means to engage and operate the member.

6.
