HERBERT WHITE RICHARDS, OF CHICAGO, ILLINOIS.

GRAIN-DOOR FOR CARS.

Specification of Letters Patent.

y Patented May 7, 1907.

Application led December 9, 1905. Serial No. 291,011.`

To all whom t 11i/Cty concern:

Be it known that I, HERBERT WHITE RICHARDS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain newA and useful Improvements in Grain-Doors for Cars, of which the following is a specification.

This invention relates to grain doors and its object is to improve the construction and operation of such doors.

lith this end in view the invention consists in the new and useful construction and combination of parts hereinafter described in detail, illustrated in the drawings and incorporated in the claims.

In the drawings-Figure 1 is a side elevation of a portion of the side of a car and a door embodying my invention. Fig. 2 is a section taken on line X-X of Fig. 1. Fig. 3 is a section taken on line YY of Fig. 1. Fig. 4 is a view similar to Fig. 1, but showing the` door in its open position entirely out of the way of the door opening. Fig. 5 is a section taken on line A-A of Fig. 4 showing the doors on both sides of the car in their wide open positions. v

Referring in detail to the several views, wherein like numerals refer to corresponding parts throughout the views, 2 represents the body of a car having side-door- openings 3 and 4, the lower halves of which openings are normally closed by graindoors 5 and 6. A description of the door 5 will suffice for both doors.

The door 5 consists principally of two parts 7 and 3 pivoted together on hinges 9, 9. Cn the member 3 and adjacent to the hinges 9, is a batten or cross-piece 10 to which are pivoted at 11, 12 and 13, crossbars 14, 15 and 16. These cross-'bars are pivoted to the batten 10 so that ends 17, 13 and 19 project normally beyond the edge of the batten 10 and the inner edge of a cross-piece, or batten, on the part 7 of the door. The edges of battens 10 and 2O meet as shown clearly in Figs. 2 and 3. On the insides of the parts or members are crosspieces 21 and 22 to which the vhinges 9 are secured by means of screws in the ordinary manner. A connecting-bar 23 is pivoted at 24, 25 and 26 to the respective latch-bars 14, 15 and 16 and serves to move said latchbars in unison for the purpose of rotating their ends 17, 13 and 19 into and out of engagement with the edge of the cross-piece 20. This edge is shod with an angle-iron 27 which serves the dual purpose of protecting said edge against wear and preventing the driving of nails through said ends 17, 13 and v19 and the cross-piece 20. On their edges adjacent to 'the vertical sides of the dooropening the door sections or members 7 and 3 have brackets 23 and 29. These brackets are of elbow form and have eyes 30 and 31 which engage a rod 32 extending horizontally across the door opening. In each end of the rod 32 is an eye or loop which vengages a vertical rod 33 on one side and a similar rod 34 on the opposite side. The ends of rods 33 and 34 are bent substantially at right angles and formed with eyes which are secured by means of bolts or screws 36 to the walls of the car.

In order to bring the latch-bars flush with the outer surface of the car-side the door 5 is set inwardly from the inside wall of the car by means, of posts 37 and 33 which form j ainbs for the vertical edges of the door, and posts 39 and 40 interposed between the inner wall of the car and the rods 33 and 34. The door, as a whole, is thus movable vertically upon the rods 33 and 34 and the individual sections 7 and 3 of the door slide on brackets 23 and 29 horizontally on the rod 32. The doors 5 and 6, as shown in Figs. 4 and 5, are supported entirely out of the way of the load s ace in the car by means of eyes 41 and 42 on the lower edges of the doors, which eyes are engaged with hooks 43 and 44 ona chain 45 suspended from the ceilingof the car, or the running-board 46. The vertical rods 33 and 34 are inclined from top to lower ends toward the wall of the car, or as the rod 33 is shown in Fig. 5. The object ofA this is to provide means for wedging the face of the door tightly against the inner wall of the car, or, rather, against the edges of the dooropening, when the door is lowered and closed. This will prevent leakage of small grain between door and side of car. The rods 33 and 34 wedge the upper part ofthe door tight and elbow-shaped brackets 47and 43 are secured to the bottom or fioor of the car so as' to form stops preventing inward swinging movement of the doors lower edge when said door is closed. The posts 37 and 33 are equipped like the edge of the piece 20, with angle- iron shoes 49 and 50 which serve in the same capacity as the shoe 27.

In Figs. 1, 2 and 3 the door is shown by full lines in its closed position and by dotted lines in its open or partly open position.

Starting from the closed position the door is opened by lifting the connecting bar 23 to the position in which it is shown by dotted lines in Fig. 1; When thus raised the ends 17 18 and 19 are rotated out of engagement with the section 7, or the angle-iron-edge 27 thereof, thus disengaging the hinged edges of the parts 7 and 8 so that they are free to move on their hinges. As said parts 7 and 8 swing on their hinges 9 their opposite edges move toward the center on the brackets 28 and 29 and rod 32. After the parts of the door have moved angularly to the position in which they are shown by dotted lines in Fig. 3 sufficient grain will be unloaded from between the door and the Hoor of the car to release the door from the pressure of the load. The door can then be raised bodily upon the guide- rods 33 and 34 until the eyes 32 of the rod 32 mount the horizontal upper bends of the guide- rods 33 and 34, as shown in Fig. 5, when said bends will support the upper edge of the door vertically. The lower edge of the door is then swung upwardly and suspended upon the hook on chain 45 during the unloading of the balance of the load. As shown most clearly in Fig. 2, the cross piece 2O overlaps the hin ed edges of the members 7 and 8 and hol s the hinge-joint rigid when the piece 2O is engaged by the latch-bars 14, 15 and 16.

In order that the door-members 7 and 8 of the door opening( may' move angularly relatively to each other that part of the cross-piece 20 which overlaps the member 8 must move angularly relatively to said member and this it cannot do when its free edge is held between the projecting ends of the latch-bars and the part 8 of the door.

I claim as new and desire to secure by Letters Patent A car having a door opening therein` a door therefor comprising two hinged sections, an overlapping hatten on the outside of one of the sections abutting against a complementary batteri on the' other section, an angle iron at the meeting edge of the battens, a plurality of latch vbars pivoted to one of the battens overlapping the joint, the ends of said bars engaging the angle iron, a connecting bar pivoted to the opposite ends of the latch bars, a rigid horizontal supporting bar upon which the opposite upper corners only of the sections are slidably connected, said supporting bar capable of vertical adjustment, and brackets to secure the lower edges of the sections.

In testimony whereof I have hereunto set my hand in the presence of two subscribing w1tnesses.
