GRAIN-CAR 000 SPECIFICATION forming part of Letters Patent No. 769,609, dated September 6, 1904.

Application filed May 9, 1904. Serial No. 207,132. (No model.)

Be it known that we, EDWARD HUBER, residing at Marion, in the county of Marion, and DAVID lnswrs FOSTER, residing at Orestline, in the county of Crawford, State of Ohio, citi- ZOIIS of the United States, have invented certain new and useful Improvements in Grain- ,lar Doors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in grain-car doors and fastenings therefor; and it consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

One object of our invention is to provide an improved fastening device for a grain-car door which will be effective also for raising and lowering the door.

A further object of our invention is to provide improved means for supporting agraincar door, which supporting means also adapt the door to be raised and fastened in an elevated position under the car-roof.

A further object of our invention is to provide improved means for clamping the door when the same is in a lowered position.

In the accompanying drawings, Figure 1 is an exterior elevation, partly in section, of a grain-car door and fastening device embodying our improvements. Fig. 2 is adetail horizontal sectional view taken on the plane indicated by the line (I a of Fig. 1. Fig. 3 is a similar view taken on the plane indicated by the line 7 b of Fig. 1. Fig. 4c is a transverse sectional view of the same in operative position in a car.

In accordance with our invention we provide vertically-disposed supporting-plates 1, which are here shown as made of angle-iron and are secured to the inner corners of the sides of the doorway, their inner flanges 2 being spaced a slight distance from the inner sides of the doorway. In the bottom of the doorway is a floor-plate 3, which rests on the sill, the latter being provided with recesses l. The floor-plate is provided with slots 5, the

outer ends of which communicate with angular engaged openings 6, said slots and openings being coincident with the recesses f in the sill. In the upper side of the doorway are bolted a pair of bracket-plates '7, each of which is provided with a pair of depending lugs 8, appropriately spaced apart.

The door 9 is here shown as a metal plate provided at its ends corresponding with the vertical sides of the door with return-bends 10, forming springs which engage the inner sides of the flanges 2 of the metal angle-plates 1. These spring return-bends effect a slidablc connection between the door and the said angle-plates and firmly clamp the door in place when it is lowered, as will be readily understood. On the outer side of the deer are angle-bars 11, which are bolted or otherwise secured thereto and which serve to stiffen and strengthen the door, as will be understood. The said angle-bars are provided with vertically-coincident openings for the reception of adjusting and securing bolts 12, which have their heads 13 secured in the recesses l: under the sides of the heads of the floor-plate, the angular opening (5 permitting the heads of the bolts to be inserted in and removed from the said recesses. The bolts are provided with lower nuts I l and upper nuts 15 to respectively engage the under and upper sides of the upper bar 11, and it will be understood that by appropriately turning the said nuts on the bolts the door will be raised and lowered on the latter. The bolts and nuts firmly secure the door when it is lowered or at any desired elevation and enable the door to be so firmly secured when in a lowered position as to effecta tight joint between its lower side and the floor-plate to prevent the loss of grain. The bars 11 are further provided with round openings for the reception of swinging supporting-rods 16, the upper ends of which are pivotally mounted between the lugs 8 of the bracket-plate T on bolts 17. \V hen the bolts 12 have been disengaged from the recesses a and the floor-plate by loosening the nuts thereon and turning the bolts to the inclined position shown in dotted lines in Fig. 1, the door may be raised on the swinging supports 16 and the latter turned inwardly to raise the door to a position close under the car-roof and support the door in the said elevated position by engaging the said swinging supporting-rods with hooks 18, with which the car is provided. The swinging supporting-rods 16 are here shown as provided with spring-keys 19 of the usual construction to prevent the casual disengagement of the door from the said swinging supporting-rods.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what V we claim as new, and desire to secure by Letters Patent, is

1. The combination with a vertically-movable door, of adjusting and securing screws connected thereto for vertical movement with reference thereto and also for angular movement with reference thereto, and a fixed element at the bottom of the doorway to which said adjusting and securing screws are detachably connected. I

2. The combination of swinging depending supporting-rods, a door slidably connected thereto, adjusting and securing screws connected to the said door for angular movement and also connected thereto for vertical movement with reference thereto, and a fixed element at the bottom of the doorway to which the said adjusting and securing screws are detachably connected.

3. The combination of a vertically-movable door, swinging depending supporting-rods to which the same is slidably connected, fixed vertical guide elements at opposite sides of the doorway, clamping elements with which the door is provided, engaging said guide elements when the door is lowered and disengaged therefrom when the door is raised, adjusting and securing screws carried by the door, connected thereto for angular movement and also connected thereto for vertical movement with reference thereto, and a fixed element at the bottom of the doorway to which the adjusting and securing screws are detachably connected.

4E. The combination of a vertically-movable door, adjusting and securing bolts on which the same is slidably mounted, fixed means to which the said bolts are detachably connected, and nuts on the said bolts to raise and lower the door and clamp and secure the door when adjusted.

5. The combination of dependingswinging supporting elements, a door vertically movable thereon and having return-bend clamping elements at its sides, and fixed guideplates at the sides of the lower portion of the a doorway and having flanges engaged by said clamping elements when the door is lowered, said guide-plates being disengaged by the return-bend clamping elements of the door when the latter is raised, to permit the door to be swung inwardly.

6. In combination with fixed guide elements, a door comprising a metal plate provided with return bends at its sides forming springclamps engaging the said guide elements.

In testimony whereof we have hereunto set our hands in presence of the subscribing witnesses.
