GRAIN-DOOR.

No. 810,267. Specification of Letters Patent. Patented Jan. 16, 1906. Application filed February 27, 1905. Serial No, 247,486.

ToaZZ whom it may concern..-

Be it known that I, JOSEPH E. DRAKE, a citizen ofthe United States, and a resident of Blue Rapids, in the county of Marshall and State of Kansas, have invented a new and Improved Grain-Door, of which the following is a full, clear, and exact description.

My invention relates to grain-doors for such structures as railway-cars, it being an ro improvement upon my Patent N o. 740,407, dated October 6, 1903. Its principal objects are to facilitate the opening of the door and to otherwise improve the organization.

Reference is to be had to the accompanyi 5 ing drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a horizontal section through a car to which one embodiment of my invenzo tion is applied, the view being taken looking upwardly and showing the doors in a raised position. Fig. 2 is a transverse vertical section on the line 2 2 of Fig. 1. Fig. 3 is a detail in elevation, showing the inner side of one of the doors and its guide. Fig. 4 is a sectional detail through the upper edge of the door and particularly illustrating the supporting means, and Fig. 5 shows in perspective one of the carriers. i

3o I have here illustrated a car A, having in its opposite sides the usual door-openings B B. Extending above and to one side of each door and longitudinally of the car is a guide 10, preferably consisting of a hol- 3 5 low or tubular bar supported by brackets 11. At the inner side of each guide-bar is a longitudinal slot 12, this lying in a horizontal plane and being shown as closed at one end. At its opposite end it may extend for the full 4o length of the bar, there being provided a stop which may consist of a pin 13, which is secured to the car by a chain or flexible memextends outside the guide and has rotatable upon its upturned cylindrical end a roll 2() for contact with the guide. Secured to each pair of supports is a door O. This includes a 6o frame having side members 2l 21, connected by an upper member 22, these elements being preferably braced at their junctures 23. Secured to the opposite extremities of the side members is a lower member 24, which is divided, there being at its center a space. The frame members 21 and 22 are conveniently formed from angle-iron having one liange extending outwardly from the car. Between the members 22 and 24 the side members are 7o connected by'a cross-bar 25, `also of angleiron and having a flange extending inwardly. Secured across the top of each door-frame at its inner side is a supporting-strip 26, which may be of wood, and to this is connected an upper door-section 27 by means of hinges 28. This door-section at its lower edge coacts with the cross-bar, which serves as a sill for it. Each door-section is provided with a securing device, which, as illustrated, is in the 8o form of a hasp 29, projecting through an opening in the vertical flange of the crossbar and engaged by a hook 30, pivoted upon said flange. Fastened upon the inner side of each door-frame below the cross-bar is a fixed door-section 31, which may be shod at its lower edge with an angle-iron 32. In this section is a space 33, extending between the ends of the divided member 24 for substantially half the distance between it and the 9o cross-bar. Connecting the adjacent extremities of the member 24 and the bar 25 are separated vertical bars 34, which strengthen the structure and also serve as guides or ways for a panel 35, which may occupy and close the space 33 or be slid upwardly to free it. The panel is shown as provided with transverse reinforcing-strips of angle-iron 36 and ber 14 and iitting alined openings 15 in the has a securing device, which may consist of a bar. In each guide-bar, opposite the doorbolt 37, carried by the panel and capable of roo 45 opening and near each side thereof, are slot j coacting with eitherof tworecesses 38 and 39, enlargements or openings 16, extending tothe former locking the panel when closing ward the under side of the bar. the space and the latter in its raised position. Operating in each guide are supports (here Each of the cross-bars 25 is extended at its shown as two in number) and each comprisends 40 beyond the door, where there may 105 5o ing a cylindrical member 17, iitting the holcoact with it securing devices or buttons 41,

This places the doors in a substantially horizontal position, in which they will continue until the shanks reach the slot enlargements, when they may be swung downwardly into coperation with the door-openings. Here they may be secured by the buttons 41, access to these being had through the upper door-sections. Each panel now being locked in its lowered position, the car may be filled through one or both of the door-sections, and when this operation is completed said sections are themselves closed and locked in place. When it is desired to unload the car, a panel is released and raised, allowing the contents of the car to iow through the opening 33. When this discharge has ceased, the doors may be freed by unlocking and raising the upper sections and turning back the buttons. Said doors may then be successively swung upwardly in the guides, the shanks turning in the slot enlargements. When they are in a substantially horizontal position, means are provided for securing them in place. As illustrated, each door has associated with it and hung from the car-roof near its inner raised end a tubular bar 42, depending from brackets 43 and having in its under side a slot 44, from which opens an enlargement 45, located opposite the doorspace 33. In the bar-channel operates the cylindrical portion 46 of a carrier, which also has a depending shank 47, from which extend opposite engaging projections 48 and 48a. When the carrier-shank lies opposite the slot enlargement, the engaging projection 48 may be swung away from the door, the shank lying in a horizontal plane. rIhe door having been raised, this projection may be turned downwardly, entering the space 33 and engaging the lower or inner extremity of the panel, and thus securely supporting the door in its raised position. At this time the Shanks of both the door-supports and the carrier are in alinement with the guide-slots, enabling both door and carrier to be slid longitudinally of the car, so th at they will be out of the way. In this travel the support-roll rests upon the upper side of the guide, as is particularly illustrated in Fig. 4 of the drawings, facilitating movement. The projection 48a servesl to engage and retain the doorsection 27 in its raised position.

IIaving thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination with a car having a door-opening, of a hollow guide extending longitudinally of the car above the opening, a supporting member iixed upon the door and being movable through and rotatable in the guide, and an arm extending from the support and having means overlying and contacting with the guide during the rotation of the supporting member.

2. The combination with a car having a door-opening, of a hollow guide extending longitudinally of the car above the opening, a supporting member fixed upon the door and being movable through and rotatable in the guide, an arm extending Jfrom the support outside the guide, and a roll upon the arm contacting with the guide throughout the rotation of the supporting member.

3. A grain-car door, comprising a frame having side members and a cross-bar connecting the side members between their ends, and having its ends projecting beyond the same, a lower fixed door-section secured to the side members of the frame at one side of the cross-bar, and an upper doorsection hinged at its upper edge to the frame and having its free lower edge engaging the cross-bar.

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

JOSEPH E. DRAKE.
