The attachment-plate, the link, and the clamp may be of any suitable metal, and the clamp, which is composed of two jaws or sections, is provided with a vertical opening 17, in which is arranged a vertical rod 18. The vertical rod 18 has its ends bent at an angle and secured to the innerface of the adjacent side of the car, and the body portion of the rod, which is offset from the car, forms a pintle-and a guide for the graindoor. rlhe grain-door is adapted to break at the center to withdraw the outer vertical edges of the sections from the vertical ways 3 to permit the door to swing inward, and the said grain-dooris adapted to be swung around to the position shown in Fig. 3 of the drawings and may be arranged in an elevated position or at the bottom of the car. The clamp has one of its sections or jaws recessed to receive the other, and the two jaws or sections are perforated for the reception of a bolt 19. The section 2 of the grain-door is provided at the upper edge with an eye 20, which is adapted to engage a hook 21 of the side of the car for holding the door in an elevated position, and when the door is arranged at the top of the car the clamp 15 is supported by a bracket 22.

The hinge connection is provided with three joints or pintles, and it permits the sections of the grain-door to be readily engaged with and removed from the ways of the sides of the doorway. The door is locked when closed by a combined brace and latch-bar 24, which is mounted on the stud 25 of one section and which engages the perforated ear 26 of the other section. The stud is preferably formed integral with an attachment-plate, and it has a threaded outer portion for the reception of a nut 27, which secures the combined brace and latch bar to the stud. The combined brace and latch-bar is provided at one end with a slot 29 to receive a stud, and it has a hook 30 at the other end for engaging the perforated ear, which is formed integral with a suitable attachmentplate. The slot will permit t-he combined latch-bar and brace to be conveniently arranged when the grain-door is notin use. Instead of employing the latchbar and brace any other suitable fastening device may be used for securing the graindoor in its closed position.

In order to relieve the grain-door of the pressure of the grain when it is desired to open the door, each section of the grain-door is provided with an opening 31, arranged near the bottom of the car and normally covered by a supplemental door or slide 32, arranged in vertical ways 33 and provided at the top with a suitable grip or handle for enabling it to be readily raised. The ways 33 preferably consist of bars provided with Iianges spaced from the grain-door to form grooves for the reception ofthe slide, which fits snugly against the grain-door. When the supplemental doors or slides are raised to uncover the openings 31, the grain will flow through the openings and will leave sufficient space at the inner face of the grain-door to permit the sections 1 and 2 to be readily disengaged from the ways 3.

What I claim is- 1. The combination of a car provided at opposite sides of its doorway with ways, and a sectional grain-door provided at the bottom with a flange interlocked with the bottom of the cai-,whereby the grain-door is held against upward movement and the grain is prevented from escaping, substantially as described.

2. The combination of a car provided at the bottom of its doorway with a groove, and a sectional grain-door provided at the bottom with outwardly-projecting Iianges fitting in the groove of the car, whereby the grain-door is interloeked with the bottom thereof to hold the door against vertical movement and to provide a grain-tight joint, substantially as described.

3. The combination of a car provided at opposite sides with ways, a grain-door arranged in the ways and composed of sections hinged together and provided at the bottom with ianges interlocked with the bottom of the car, and the vertical cleats or bars secured to the inner faces of the sections and covering the inner edges of the said sections at the joint, substantially as described. i

4. The combination of a car, a grain-door composed of sections hinged together and interlocked at their bottom and outer edges with the car and provided with openings, slides normally covering the openings, and means for securing the door, substantially as described.

5. The combination of a car, a grain-door composed of hinged sections, one of the sections being provided with a keeper and a combined brace and latch-bar slidably connected with the other section and provided with means for engaging the keeper, substantially as described.

G. The combination of a car, a grain-door composed of hinged sections, a stud mounted on one of the sections, a keeper arranged on the other section, and a combined brace and latch-bar provided with a slot receiving the stud, said brace-bar being also provided with a hook for engaging the keeper, substantially as described.

7. The combination of a car, avertical rod secured to the car, a clamp mounted on the rod and adapted to swing horizontally and slide vertically, a grain-deci' composed of sections, and a link hinged to the clamp and to the grain-door, substantially as described.

S. The combination of a car, a vertical rod secured to the car, a clamp composed of two IOO Ilo
