To all'whomz't may concern: I

,Be it known that I, IIEINRICH WILHELM FRIEDRICH Janene, a citizen of the United States, and a. resident of Cleveland, in the county of Cuyahoga and State of Qhio, ave invented a new and Improved Adofwhich the follow- This invention relates to improvements in doorsfor cars designed to carry grain, and has for an object to. provide an improved structure'which may beadjusted or expanded so as to. permit grain of different weights to be shipped in the same car without changing the door and without reducing. the amount of grain which may be safely shippedin any particular car.

Another object of the invention is to providea grain door formed in a plurality of parts and arranged with apertures on one side co-acting with a locking pin designed to be projected through the respective apertures according to the height of'the adjustable portion ofthe door so as to hold the In carrying out the objects of the invention, a door is provided which is hinged in position in the car so as to swing or to be pivoted to one side when it is desired to oi the .door.

One construction of a grain door of a somewhat similar nature to the present invention is disclosed in my Patent No. 554,932, issued February 18, 1896. In the present invention the same shows an improvement over this former patent by the particular arrangement and construction of the door and means for holding the same in various positions. The door is provided with a lower portion which is pivotally is attached, and which is associated with a movable portion designed to be raised upward to close to a greater or less extent the entire doorway; A pin is arranged in one side of the door casing which is adapted to be projected through various apertures provided in the adjustable door at various times so as to hold the door at varying heights. This is of advantage as the different grains have different weights. When a heavy grain is being shipped, as for instance wheat, the adjustable portion of the door is left in its 'lowermost'position as the car will not support more than approximately half of a load, while lighter grain, as for instance ing's oats, may be placed in the earuntil the car 18 two-thirds fullor possibly more. In

order to prevent the oats from being discharged out the door, .of thedoor is raised to a point preferably slightly above the upper level of the grain.

the adjustable portion I A practical embodiment of the invention s represented. in the accompanying draw-- Fig. 1, except that the Same is looking from the interior of the car outwardly;

and Fig. 4 is a section through Fig. 3 on 4 4 4 the line accompanying drawings by numerals, 1 indicates a car body of any description, provided with the usual door opening 2 in which is arranged a grain door Referring to the 3. Arranged adjacent the door opening 2 is the ordinary outside sliding door 4 which not only covers the door opening but also the grain door 3 when in a closed position. The door 4 may be of any desired or usual construction. The door 4 carries a projecting hook 5. a locking staple'6, and

a bolt or latch 7. When'the door 4 is closed the hasp 8 is moved over until the projection 9 fits over the projecting hook 5' and the staple 6 is caused to project into the slot out 10, the hook 7 being previously moved of engagement with the staple.

The hasp 8 is provided with a pressed out cup-shaped portion 11 which fits over the end of a pin 12 and also over the operating ring 13 connected therewith and protects the same against being tampered with when the hasp 8 is closed. been closed the book 7 is again caused toengage the staple 6 so asto hold the door temporarily closed, or a lock of any kind, as for instance an ordinary padlock is brought into engagement with the staple 6 when it is desired to positively prevent the opening of the door. The door 4 is an outside protectforming a partof this specification, in M which similar characters of reference indi- After the hasp 8 has ing door, while the door 3 designed to sustain the weight of the gram in the car, and

door portion 1a. The outer door portion 14 is provided with an apertm'e near the topfor accommodating the pin 12, and an aperture near the bottom for accommodating a pivotal pin 16. Preferably the lower edge of the inner adjustable door portion 15 is held normally in line with the upper edge of the pin 16 when in the lower position.

i The adjustable door portion'15 is provided with a plurality of apertures 17 into which the pin 12 is designed to be thrust or projected whenever it is dcsired'to hold the moved upward until the handholds 21 and Goblet of this patent maybe obtained for 22 are in position to have the hooks 23 and '24: positioned therein for holding in an elevated position the door portion. This is desirable Where hay or other light material is to be shipped. "By the construction and arrangement of the pin 12 and associated parts with the aperture 17, the inner door portion 15 may be easily adjusted at any height,

While by the provision of the pin or bolt'16 the car door 3 may be swung to one side, as

shown in dotted lines in Fig. 3, for expos-- ing the entire door opening.

Having thus described my invention I claim as new and desire to secure by Letters Patent 1. In a grain door of the class described, the combination with a door frame, of a pivotally mounted door, a stationary pin for, pivotally connecting said pivotaily mounted door with said frame, a reciprocating spring pressed pin mounted in said frame, an aperture formed in said pivotally mounted door for accommodating said pin whereby the pivotally mounted door is locked against adjustable section pivotal movement when the reciprocating pin is projecting into said aperture, a vertically adjustable section associated, with said pivotally mounted door, said vertically adjustable section being formed with a row of apertures adapted to accommodate said reciprocating spring-pressed pin at ditierent places whereby the vertically adjustable sec tion is held in its adjusted position and said pivctally mounted door is held against. pivotal movement.

in a grain door-of the class described, the combination with a stationary door frame, of a door pivotally connected there with, said pivotal cpnnection being at one of the lower corners so that the door may be swung pivotally in a plane parallel with the frame, a pin adapted to extend through said frame and into said door, and a vertically formed with a plurality of apertures associated. with said door, said reciprocating pin'beingadapted to fit into any of said apertures for holding said sec tion in various adjusted positions and simul taneously locking said door against pivotal movement.

3. In a grain door of a door structure member, said door structure being formed Withan aperture near the upper edge and said extension member being formed with a row of apertures near one edge designed to at various times registerwith the aperture in the door structure, a journal member passing through one part of said door structure and extending in such a direction as to cause the door structure to move pivotally only in a vertical plane, a locking pin adapted to project through any of the apertures in said extension and through the aperture in said door structure, and means for normally hold ing said pin in said aperture.

In'testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
