HENRY I-I. FREY, or NEWTON, KANSAS.

GRAIN-DOOR FOR CARS.

Specification of Letters Patent.

Application filed February 9, 1911.

Patented Oct. 10, 1911. Serial No. 607,470.

To all whom it may concern:

Be it known that I, HENRY H. FREY, a citizen of the United States, residing at Newton, in the county of Harvey and State of Kansas, have invented certain new and useful Improvements in Grain-Doors for Cars, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to grain car doors and has special reference to that class of grain car doors which cover only a portion of the door opening, and which are adapted to be moved out of the way and suspended within the car.

The invention has for its objectto provide an improved grain car door of this kind which is so constructed and arranged that it may be partly opened to increase the size of the opening, and also to permit of its being folded up into position when not in use.

Referring to the accompanying drawings Figure 1 is an outside view of a portion of the side of a grain car showing a door opening and a door constructed in accordance with thi invention mounted in said opening. Fig. 2 is a view in vertical section of the door and car frame. Fig. 3 is a view in longitudinal cross section. Fig. 1 is a view in vertical section of the door car frame, showing the door folded up and secured beneath the roof of the car. Fig. 5 is an inside view of the car door and opening therefor constructed in accordance with this invention. Fig. 6 is a detail view in perspective of the car door. Fig. 7 is an enlarged detail view of a hook for securing the car door when it is folded up and suspended beneath the roof of the car.

In the accompanying drawings the door posts 1 of the car door opening are each provided with a vertical groove 2 which connects with a horizontal groove 3 in the sill 1 of thecar door opening. The grain car door is formed in two parts with the main lower part 5 and the narrower upper part 6 hinged thereto by hinges 7. The upper edge of the part 5 and the lower edge of the part 6 fit together by means of the rabbet joint 8 to form a tight joint and thereby prevent the escape of grain. The grain car door adapted to be seated in the grooves 2 has its bottom edge seated in the groove 3, the width of the door being such that it may be placed from the rear of the door posts into the grooves 2. The door is held in the lower end of the grooves 2 by means of the short posts 9 overlapping the door posts 1 and the grooves 52 as shown in Fig. 5,said posts 9 terminating at their upper end even with the upper edge of the lower portion 5 of the grain door, thereby permitting the upper portion 6 of the door, when desired, to drop back inside of the car. In order to hold the upper portion 6 of the grain car door in vertical position, suitable fastening means is provided, as for exam ple, the latches 10 each hinged at one end to a door post 1 and adapted to swing down on the upper portion 6 of the car door and being provided with a notch 11 which is adapted to engage a pin 12 on the portion 6 of the car door. In order that the notched latches 10 may be out of the way when not in use, a slot 13 is provided in each of the door posts 1 in which each of the pivoted latches 10 is adapted to be seated when not 1n use.

The lower portion 5 of the grain car door is provided with a small suitable closure or door such as the triangular door 14, which is adapted to be seated in a triangular opening in the door and is held in place by any suitable means, as for example by means of a latch 15 pivoted to the door on the outside thereof and adapted to be swung across the door 141 and to be held in locked position over the same by means of a notch 16 in the latch 15 which engages a pin 17 on the door. The door 14 is provided with suitable means for moving it into and out of position in the opening in the door, as for example, a ring 18 which engages an eye staple 19 secured to the door 14 and projecting through a notch 20 in the latch 15. It will be seen that by means of this construction by swinging the latch 15 out of engagement with the pin 17 and away from the door 1 1, the latter may be pulled out by means of the ring 18 thereby permitting the grain to discharge through the opening in the portion 5 of the grain car door and releasing the pressure of the grain thereon so as to permit the door to be opened by sliding it upward.

In order to raise the door when the upper portion 6 has been unfastened, handles 21 are provided on the door by means of which it may be raised up in the grooves behind the posts 9 and when the door is not required for use it may be raised up in grooves 2, and suspended out of the way. For this purpose the lower portion 5 of the grain car door is provided with sultable hooks as for example the metalllc strips 22 secured to the outside of the lower portion 5 of the.

door and each formed at its upper end with a book 23 which may be engaged with a rod 24: extending across the upper end of the door opening secured to the door posts 1. The door mounted on the rod 9A may be swung up into folded position as shown in Fig. 4, the upper part 6 of the door being folded against the under side of the roof of the car with its rabbet joint fitted against the corner of the longitudinal beam 25 of the car and the lower portion 5 of the door being folded up horizontally and parallel with the upper portion 6 and held in such position by means of a suitable catch as for example the hook 26 formed of an iron rod bent into hook shape and hinged to the roof of the car as shown in Fig. 4.

It will be seen that by means of this invention a grain car door is provided which can readily be mounted in place to cover the lower part of the door opening of a grain car and also may be extended so as to cover the greater portion of the car door opening. It will be further seen that by means of this invention the grain car door may be readily moved out of the way when not in use and folded up in compact position beneath the roof of the car.

What I claim is In combination with a car having a door opening, of a grain door verticallyslidable in said door opening, said door consisting of a lower section and an upper section hinged thereto, said sections being provided with a rabbet joint, a horizontal rod secured to the sides of said door opening, and extending across the top thereof, metal strips secured to the outside of said lower portion and extending beyond the upper edge thereof, said strips having their free ends terminating in a hook for engagement with said horizontal rod, when said door is in a folding position, the rabbet end of said upper section adapted to engage the edge of the top of said door opening when the door is in a folding position, means for retaining said door in a folding position, and means in said lower section for discharging grain.

In testimony whereof I hereunto afliX my signature in presence of two witnesses.

HENRY H. FREY.
