' To all whom it may concern: l

Be it known that I, PAUL F. Busen, citizen of thevUnited States, residing 'at-Cleve- 'of Ghio, have invented certain new and useful linproveinents in Grain-Doors for lGars, of which the following is a speclcation.

My invention rela-tes to an improvement in doors .for grain'ca-rs, all substantially as shown and described and-.particularly pointed but inth'elelaiins.

'I ln the accompanying drawings,v Figure l 1 Visfar side elevation of a ear embodying iny inention, -and Fig. 2 is an enlarged cross section. Fig. 3 isfa plan of the immediate eontrolling means for the doors, and Fig. 4 is a perspective viewof one of the doors and of the controlling -meansA in working relations therewith. `Fig. 5 is a plan View of one of the quadrangu'lar posts and a 'section of a door therein. 1 The leading idea'of provide a tiexible door for grain cars adaptway when not wanted. provide a door D for each side of the car ed to'slide in guidewaysvat the edges ot' the door 'opening and extending beneath the car so asto run said'doors down out of the To these ends l C, and this door is supplemental to the usual outside sliding door B., The said door D is constructed from a series of corresponding slats or pieces 2 otsheet metal provided eaeh with an otlset,k portion 3 at what becomes the inner upper edge, said oset portion having a right angled shoulder of a depth equal to the thickness of said strip so as to make a plain and smooth interior adapted to eonline the grain at the saine time that -the doorV or gate will flex to turn the angle oi curve which will bring it beneath the ear. At further peculiarity of the construction of this door` is the hinges l which connect the l slats or plates Q, said hinges being provided near the two ends of the slats on the inside opposite the said offsets 3. lt follows that the said doors can bend or flex in making the turn beneath the car but lie perfectly dat one against one another in said otliset por tion when up in using position, This ot course atl'ords the desired closure tor grain and enables either door to be opened more or less or raised more or less when a ear is being tilled'with grain and also to be lowered and run entirely out of the way when.

the inventionis to lsary room for storing saine.

thejcar is unloaded or when it is used for other purposes. v One of the material advantages of this airangement of doors, or 'construction of ear, is that when they grain is stowed away out ofuse it is out of the Way in every respect and leaves the car with its full caf paeity and-room to receive any other coniinodity than grain up to the roof. The guides or runways for said doors are shown as substantially square sectioned or four sided posts or boxes b, which extend down to the bottoni of the car in this or equivalent forni and are supplemented beneath the ear by the bottoni b as seen in Figvl. Each slat or plate is further provided with 4a seetion 5 of what becomes as a whole a toothed. raek R upon the inside of each door at the. edge thereof, and these rack sections. run in the said guide boxes or'ways b and confine the gate laterally as to said parts. Y

l) represents a pinion engaged with each of Vsaid racks,V` in the angle where door D runs beneath the Ifloor of the car ontol guideway or support o beneath, and the said guideways ZJ for the opposite doors overlap beneath the ear so as to provide the neces- Said pinions are mounted on a shaft S transversely of the 'door opening anda bevel gear G thereon is nieshed by a corresponding gear G on a hand actuated shaft S which is located at one side of the door and practically out ot the way and has a hand wheel H for controlling saine. The pinions P mesh with the racks R and serve to operate the door D both ways. Respecting the said door or doors, it is to be further observed that there a skip or opening in the lower portion thereof or between the so-called lower slat l0 ot the door series proper and the end slat l2 while the rack R continues across said skip or opening on a flexible steel strap ll connecting said slats l0 and l2 at its ends.' The said opening is useful only in unloading or emptying a car iilled with grain' or other like iiowing material. and is inade available for this purpose. ,These guidesl extend upward 'within the ear relatively to the top tliereoifr.,as seen in Fig. 2, wherein the door D also has been run upl to its limit and the "opening O- therein is exposed at the bottom in Fig. 4, or at the left, Fig. 2, and in which said case it is at least above the highest filling level of lthe grain in the car.

7What I claim is:

.1. A oar having a door opening in its side 'and a guidewa)Y for the doorbeneath the car communicating with said opening, said door havingl a flexible toothed rack on its inside along each edge and extending below the lower edge ofthe door, a shaft having p'inions located in the angle between said guideivay and-said door opening, and a hand con- 4trolled shaft for controlling the door, whereeach side having sections corresponding to said-slats, guideways for said door extending beneath the car body, pinions in operating engagement 'with said racks and hand controlled means to operate said pinions and raise and lovver the door, the said racks eX- tending beyond the. lower edge of the door and flexible straps supporting said extengrain door consisting of a. series of slatsv hinged together and extendingl into said guidewavs and slat provided with a section of a continuons toothed rack confined within said guideways, a shaft at the bottom of said' door opening having pinions meshing with said racks and a gear on one end, and a hand controlled gear meshing with said gear and adapted to-operate said door.

In testimony whereof I aflix my signature in presence of two witnesses.

PAUL F. BUSCH.
