Application tiled July 3l, 1905. Serial No. 272,041.v

Be it known that I, WILLIAn J. CoCKLiN, a citizen of the llnited States, and a resident of Rising (fitnv. in the county of Butler and State of Nebraska, have invented a new and Improved Grain-Door, of which the following is a full, clear, and exact description.

'Ilie invention relates to a door or freightcars of the type known as "boit-cars;7 b v which door the cars may be reni'lered sutl'icientl)r tight to permit loading grain in hulk. The object ofthe invention is to siinplif)r the construction of the door, render it stronger or more durable, and permit it to be readil;V folded, so that it will not interfere with using the car for other freight.

'lhe invention resides in certain special features of construction and arrangement of parts, as will be fully set forth hereinafter and particularlyv pointed out in the claims.

Reference is had to the accompanying drawings, which illustrate as an example, the preferred embodiment of my invention, in which drawings- Figure l is airouter side elevation of the door closed. Fig 2 is a cross-section on the line 2 2 of Fig. 1 and showing by dotted lines the folded position of the door. Fig. 3 is an inner side elevation of the door closed, parts being in section on the line 3 3 of Fig. '2. Fig. 4 isa section on the line 4 4 of Fig: 1. Fig. 5 is a section on the line 5 5 of Fig, 1. Fig. 6 is a detail of one of the dogs for holding the door closed, and Fig. 7 is a sectional view showinga modification.

Referring to Figs. l to 6, I() indicates the upper section of the door, and Il the lower section. 'lhese are provided with buttstraps I2, connected b v a horizontal rod I4, wherebyY hingedlv to join the sections oi the door. 'l`he lower section Il is provided at its edges with metallic bindiiig-plates I6, which abut against the inner face of the frame I9 of the door, and cleats oi battens 15,secured to the inner sides thereof. 'lhesc cleats carry stop-plates 2t); which overlap the side edges of the door-section Il and prevent inwaiil movement thereof. 'l`hc edges of the plates of the door, and at the outer side of the door intermediate portions of the binding-plates or beads, and have latches l 7 pivoted thereto, which are arranged to engage in cavities t8, tormed in the door-trame. 'lhe binding- 3 for the door-sections.

plates lo are fastened to the door-sections by rivets or other suitable means. By this means a tight connection is effected between the lower section 11 and the frame of the door. and b v releasing the latches 17 the said section ma)Y be swung'outward on the rod 14 andraised against the upper section. .I indicates a hook in the outer side of the section It) for holding the lower section raised. At its lower edge the section I1 has a metallic binding-plate 12.

'l'he upper section It) has a bindingplate 22% at each side edge, which plates, as shown best in Fig. 4, have their edge portions engaged with and fastened by rivets or other desired means with the respective faces of tle door-section. Intermediateportions of t'hese' plates .23 stand or project outward from the outer face of.the door, producing beads which are locatcdinward ofthe cxtreme side edges of the door toform rabbets 2f Each doorsection I() engages the inner side of the door-frame, while the said bead abuts against the inner face of the frame, the rabbets 23 of the bonciiig-plates receiving the vertical inner edge of said frame. Latches '24 are pivoted to the beads -of the plates 23 and are adapted to engagc'in the cavities 25 in the frame of the door, the same as the latches 17 before described. The hinge-butts 12 before described are fastened,respectively, to the adjacent edges of the upper and lower edge sections, while the hingediutts 12 are fastened, respectivclyaothe beadsotthebinding-plates It and 123, as shownin Fig. 1. In addition to the function above nainedthe beads which arc formed on the bindingplates lt and 23 serve also as strengthening posts or columns rlhesc strengthening membersextendingaloiig t he vertical edges of the door lend strength thereto and great-ly increase the durability of the parts. On this lower edge the upper section If) ot the door is provided with a binding-platc 33. The upper edge section is hung by rods 26, which have their lower ends arranged to turn in bearings 27,attaclied to the inner side of the l section 10, and their upper ends in bearings 16 are respectively fastened to the side faces i 2.', attached to the joist '2Q over the door, as

Fig. Isliows. t he ends of the rods beingturned to torni journals rocking in the bearings, so I6 stand away lroin the door, forming cleats that the rods ina swing with the door around the center of the bearing EN. These rods permit the door to assume the active position shown in the drawings and to swing upward Vmay befolded sidewise, 'as shown in Fig. 3, ithenotches32"1 of the socket-piece 32 holding 'ranged as shown by full lines to -effectually put out of' the way.

'plates the use of a door formed in a single sec .tion 36, this section being provided .with an .openin a smal er door section or closure 37. `closure 37 is connected to the section 36of the door by a hinge 38 at the outer edge of .the closure 37, and it is provided with a suitiahle' latch for holding it securely in closed ponailed, and the iron bindings prevent persons othe folded position shown by dotted lines l in Fig. 2. f f

Attached t i the upper end of the section i0 is a hook 30, which #is adapted to engage a sling 31, projecting down from the center roofjoist of the car, as shown in Fig. 2. This holds the door raised at this point. The joi'st 29 is provided with two socket-pieces 32, having notches 32a in their upper ends, the socketieces receiving the headed Shanks 33 of an ers 34,. which are positioned to enfrage the owei edge of the section 10 when folded and to sustain the same; as shown by dotted lines in Fig. 2. The hangers when not in use the hangers in either active or inactive position. i

In the use of the door` the arts are are osethe doorway and keep the grain in the car. The car is providedwith the usual sliding door, which covers the doorway` and'grain-door, as will be understood from the prior art. To unload the grain the lower section 11 should be swung f up against the section 10 and temporarily fas-` tened by the hook 21, thus allowing part of the grain tofiow out the doorway, the remainder vbeing shoveled out. To fold the door whenv using the car for, other freight than grain, the section 11 should be swung back on section l() and fastened by the hook 21. Tlienboth sections should be thrown up (as shown by broken lines in Fig. 2, and hold' by the hook 3() and hangers 84.

It will be seen that the device when in use forms a thoroughly tight door, preventing the escape of'any of the grain,v and when it is desire( to use thecar for other purposes the door may be folded into inactive position and The modification shown in Fig. 7 conteni- 36a in its lower portion which receives The s ition. Said closure 37 takes the place of thehinged lower section hereinbefore described. Myimproved door does not need, to be from driving nails, thus prolonging the life of the doors. A l i Having thus described the preferred form of my invention, what l claim as new, and desire to secure by Letters latent, is

1. 'In a-grain-door, the combination with a car having a door-opening therein, of upper and lower door-sections, means for hngedly connecting them, means for supporting the d oor-sections,`a` 'metallic binding-plate run.
