Application filed a ru 22,

grain doors for railway cars, and thefobject 5 v, of my invention is t0 COIlStI'l1ClS adoor pro vided with means for securing it, without plurality a p vention consists in certain novel features of nailing, in a car door opening and to construct the lowermost endof the door of a 'of'hinged'sections, which may be manipu ted-to permit grain to flow from the car, so that the. pressure of the grain may be released from the door in, order that the door maybe elevated" for the further removal of the grain from the car. 7

With the shove purposes in view my ins construction and arrangement of parts as will be hereinafter more fully described, pointed out in,.-the,claims and illustrated by the accompanying drawings, in which- Figure 1 is a longitudinal, sectional elevation of a grain car equipped with a grain door constructed according to my invention; Fig. 2 is a fragmental, transverse, sectional elevation of a car equipped with one of my improved doors and filled with grain; Fig. 3 is aview similar to, Fi 2 illustrating the rain door partially op 11 and the grain fiowing. from the car; Fig. 4 is a transverse, sectional elevation 'of.a grain car equippedwith a pair of my improved doors; and Fig. 5 is a sectiom l plan taken on the line 55 of Fig. 1.- 7

Referring by numerals to the accompanying draw' gs: '6-6 designate the door posts to which are secured the stops 7. M

To the lowermost end of the body portion 8 (if my improved door are hingedly secured the hinged sections 9.

10 designates az bolt which is inserted through an openingformedin the, floor of the car between the posts 6, as required to hold'the hinged sections 9 of the'door par.- allel with the body portion 8.

11 desi ates door keepers or dogs which are hinge to the door posts'6 and arranged- Specification of Letters Patent.

1912. Serial No. ceases to hook over the top of the body portion 8 of the grain door so as to hold the doorin position between the stops 7.

12 designates guide rods secured to the posts 6 above the stops 7. v

13 designates straps which are secured to the body portion8 of the grain door and 'in each of which there is an eye 14 for the support of the links I5, which links are arraggeid to embrace and slide upon the guide ZI'O S f off-set 16 in which the links 15 rest whenthe Z door is elevated, as shown by dotted lines in Fig. 4.

Carried by the. ridge pole of the car is a pair of overhead door catches or hooks 17 which support the inner ends of the body portion 8 when not in us v Secured to the inside face of the side 'plate of the car above the door opening is sh-aft 19, the opposite end of the shaft be wing journaled in a bearing 20 suspended from the roof of the car.

21 designates a ratchet secured to rotate with the shaft 19.

22 designates a pawl which'is gravity aotuatedto permit arotation'of the shaft 19 in one direction only I 23 designates a lever which is pivotally supported upon the shaft 19 and w ich carries an integral dog 24 for engagement with the ratchet Wheel 21. The lever 23. loosely embraces: the shaft 19 so that it may be moved lengthwise thereof,- 24; may be moved out of the ratchet 21.

25 designates a ring which is suspended from the roof of the car for thesupport of the free end of the lever 23. I

26 designates a flexible connection having one of its ends connected with the bolt 10 engagement with arranged to be wound around the shaft.

27 designates eyes which are secured to nections between the connection 26.

In the practical operation of my improved door, assuming the car to be filled with grain as shown in Fig. 2, the operator releases the ring 25 from the lever 23 and eyes 27 and the flexible Patented Sept. 1 7, 1 912.

Formed in each of the guide rods, is an a metallic plate 18 in which is journaled a.

whereby the dogand its other end secured to the shaft 19 and the lowermost jone of the hinge sections 9 of the car door, and 28 designates flexible conmoves the lever so as to bring the dog24 to engage with the ratchet 21. Then, by a rotation of the ratchet wheel, the shaft l9will act as a drum and wind up the flexible connection 26 so as to release the bolt 10 to permit the hinging of the sections 9 of the grain door. A further mani ulation of the lever 23 will cause the flexi 1e connections 28 to draw out or causethe hinged sections 9 to assume the positions shown in Fig-3; thereby. permitting the grain to flow from the car so that the weight of the'grain will be taken away from the body portion 8 of the grain door. The operator then releases the door kee ersill and elevates the entire door, the lin loj-goiding the door over the rods 12:50 thatjthe links will" be brought to the olt-sets 16. The doors are then swung to the positions shown Fig. 4 and'their' inner ends secured in an "elevated position by the tootsie; Theunloading of the car then proceeds-hire. common mannen'v If it be desired'to again reload thelcar with grain the hooks 17 i are releasedafrom the 111116! ends of the doors and the'doors are moved downwardly between the stops 7 and se cured by the keepers: 11. The'bolt 10 isthen placed in position to'prevent hingingof the sections 90f thedoor.

It is" obvious from such. a construction that the :door may be repeatedly used, as

Copies otthispatent may be obtained for five cents cash by addressing theflommilsioner of Eatents,

there is no nailing or other like securing of the door.

I claim: L 1. In. combination with a car having door posts, a stop carried by each post, a guide rod carried by each post, a grain door hav-. ing a rigid body portion provided with a the rigid body vportion intplace in the .car,
