24 claims.

This invention pertains to improvements in grain door for railway cars.

More particularly it relates'to outside doors for use on railway cars of the type used for shipping side cf the car, made wholly ployed in the capacity of a grain door for re-4 grain, the door of A5 my invention being of a form for use on the 'outof metal, and em* placing' thel quite well'known wooden inside door.

One of the objects of the invention is to provide an outside grain door that will be thoroughlyy proof against leakage of grai which it is installed.

Another object lies in provi n from the car on ding a door having separate parts movable relatively to each other by which the loading and un loading of a-car is doorparts of which can belo relatively to the car, and by mechanism.

cked relatively and the use of a single Other objects and advantages will be apparent from the following description aided lby the appended drawings forming part hereof, it being stated at the outset `that changes of minor nature may be made without departing from the spirit of the invention or from the terms of the claims to follow.

ating one of such )door-supporting track 2.

(Cl. ,2U-27) Figure 9a 4shows in perspective part of a ymain door section. Part 'of a railway car is denoted by the character l over the doorway of which' is any usual Suspended from the track is a main doorsection 3 by means of hanger portions it as parts of the latter, in this instance', and lying in the same plane therewith, said section being. spaced at its upper edge' some distance from thetrack, and whose .lower edge, also, is spaced well above the floor 5 of the car. In addition to the said hangers 4 the dooris provided with depending portions Eat each of its Vertical edges, and these may also be parts thereof and lie in the same plane therewith. These. portions E at their lower ends are `upturned into hooks 1, Figuresf and 9, to engage beneath a flange' on the lower` side of a guidemember 8, for example, fixed in position below the'doorway, and along which the said hooks are freely movable.

The space above the main door section 3 is designed to be closed by a second door section 9 having a hanger I0, for example, for suspending one thereof from the saidtrack 2, the lower edge of this said section slidably engaging opposite surfaces of thek section 2 at its top edge, said edge being preferably formed with an oiset as in Figures 5 and 9a to'hang more directly in line with the track 2, 'it being observed that a graintight joint is preserved between the associated edges of the sections.

1 The space below the section 3 is closed by a third'door section Il which lies just behind and inward therefrom as in Figure 5, preferably occupying a position between said section 3 and an inner reinforcing sheet 3 secured to the latter and covering substantially the entire inner face thereof but spaced therefrom for the purposes v stated, the character 32, Figure 4, denoting la spacing member at one edge of these parts.

Y A stud l2 is fixed in an extension 6 of one of the" depending portions `6, for instance; of the door section' 3 and extends to and through one end of the section l I, and a Worm-wheel IZ'is afxedthereto. `Said section Il is loosely mounted on said stud and is adapted to turn about the same, there being mounted on said section H' between ears i3 thereon a worm i4 meshing with said worm-wheel l2. terminates in a squared end I3 to receive an operating wrench, not shown, said squared end lying Ydeep within a tubular portion I32 so that a wrench of a, special socket type is required to Y 'reachit '-On one ofthe jambs at the doorway issecured Preferably the worm shaft Y an L-shaped strip I5, Figure 4, so stationed as to receive the edges of the door sections 3, 9 and I I, bracing them against the load of grain and preventing leakage of the latter.

In order that loss of grain may be prevented at the opposite jarnb for the doorway a trapping means is provided. That is to say, in Figures 6 and 7 at said jamb a strip I3 is secured, said strip having an extension I 'i spaced from and paralleling the outer wall surface of the car. The section 9, Figure 6, has at its vertical edge a return hook portion I 3 which in the closed position of said section engages behind the said extension I'I. Again, in Figures 7 and '7a the main door section and the section Ii both have the hook portions 33 and I I', respectively, for a like purpose, a gra-in tight joint resulting throughout the entire height of the doorway.

Since the upper section 9 of the door is slidable it can be opened to permit entrance of a grain spout through to load the car, and sampling of the grain can be done through the same opening. When it is desired to sample the grain nearer the floor of the car this can be done through an opening 2D in the lower section II which is normally closed by a part next to be described. By pivoting section II it can be raised to discharge the grain through the action of the worm and Wormwheel mechanism previously described.

One of the purposes of the invention is to lock the sections 3 and 9 at one operation, when sealing the door as in usual railroad practice. Secured on the lower portion of the section 3 is a bracket 2i pivoted on which is a lever 22 whose lower end in its swinging movement' may either overlie or expose the said opening 2D, said opening being closed, of course, in the locked and sealed position of such lever. Pivoted to the lever near its upper end is one end'of a bar 23 whose otherend is pivotally connected to a lever-arm 24 on a rock-shaft 25 journaled on said section 3, said rock-shaft extending to the upper section 9 and having at its end an arm 26 arranged to enter an opening 21 ina plate 28 fixed on said section 9. 29 to engage the bracket 2I, and also carries a hasp 30, for instance, to engage any usual staple 3I through which a pin or bolt 32 may extend to receive the customary railway seal 33.

In the position of the named parts shown in continuous lines in Figure 1 it will be seen that the vopening is covered. And in this position, also, the arm 26 of the rock-shaft 25 engages -in the opening 2l of the plate 28. However, when in the position shown in dotted lines the said opening lies exposed and the arm 26 is free of the plate'28 so that the upper section 9 may be shifted. The latch 29 serves to prevent chance opening of the door as a whole when the hasp 30 is disengaged from the staple 3| as might occur during switching operations.

While the lower section II may, ofpourse, be

Ialso locked by a slight change from the structure shown itis in effect locked through the Worm v'and worm-wheel operable only by the special `wrench already mentioned so that miscreants cannot easily Vcause trouble.

It is to be observed that Whereas certain of the operating parts for the section I I have heretofore been mounted upon the vcar itself they are in this instance carried on the door entirely. Thus the dooris a complete unit ready for installation on the zcar.k

It is to be observed that since the wormwheel -I2- isrxed with respect to the main door section The lever 22 carries a latch Y 3, the section II will be moved about the stud I2v by the worm which travels around the said worm-wheel during rotation.

My door structure, in eiect, adds the upper and lower sections 9 and Il, respectively, to the: outside door in common use and thereby an all-- purpose door results in that both a grain door, by special structures, and a door for ordinary merchandise can be accommodated. The usual outside door canonly, of course, be used for one purpose, being fit only for commodities other than grain.

Again, the door of my invention by providing the upper andY lower door sections in an outside door permits ready loading and unloading of the grain thoroughly appreciated by persons having full knowledge of such matters.

' Due to the fact that such an operating arrangement as the worm and worm-wheel is used by which great power is possible, the door section I I can be readily raised even when the weight and pressure of grain liesagainst it. rOn the other hand, because of the fact that the said section passes between the portions 3, 3 of the main door section the weight of grain and the friction thereof against said sectionl II is constantly decreased as the latter moves up behind the inner portion 3. Thus the section is even more easily operated, requiring less and less power the higher it is lifted.

I claim:

In an outside door for railway cars, a main door section disposed'to cover the middle height of the doorway of a car, a door section p-ivotally mounted on the main door to cover the space beiow the same and shiftable parallel to said main door, and mechanism for swinging the pivoted section, such mechanism being jointly mounted on the door sections.
