JOHN P. POLNASZEK, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-HALF TO i ANDRE L. BINET, OF ROBBINSDALE, MINNESOTA;

GRAIN-CAR` STRUCTURE. l

Application filed April 19, 1926. Serial No. 102,844.

Thisfinvention relates' to boit'V car con-- struction and especially to an attachment for facilitating the removal of grain d-oors employed instandard box cars.

lt is the main object of this invention to provide an extremely simple but highly eiiicient box car construction or attachment therefor, which -will quickly deliver the grain within a car adjacent the grain doors at either side of the car, thereby permitting the grain doors to be readily removed without becoming damaged.

A further object of the invention is lto through the bottom thereof adjacent thel doors and slidable gates for closing or opening said passages adapted to be operated from without the car and normally held in closed position. v l

A still further object is to provide in combination with this device, a delivery chute` for each passage, adapted to drop the grain at therespective sides of the car in the usual grain pits. t

These and other objects of the invention will be apparent in the following description'made in connection withl the accompanying drawings, in which like characters refer to similar parts throughout the several views, and'in which Figfl is a fragmentary side elevationof a portionof aboX car made in conformance with my invention.

Fig. 2 is a cross section on the line 2 2 of Fig. 1. f

Fig. 3 is .avertical section taken on the line 3-3 of Fig. 2.

Fig. 4 is a detail cross section of one of my devices on a larger scale taken on the line 1 4 of Fig. 1 and showing my device sealed up for shipment, and

Fig. 5 is a fragmentary cross section of my device showing the connection of the operating handle with the gate.

A preferred embodiment of my invention is shown in combination with a standard freight car of the boXtype. The car comprises the sides 6 having the usual door ways formed in the central portions thereof, and supported on the longitudinally extending central beams 7 and the side beams 8. The bottom of the car is indicated by the nu# meral 9 and a 'grain door of any suitable construction is indicated by the numeral 1() f mounted within one of the door ways.

I preferably rrecess the sides of the car bottom 9 centrally of the door ways to aord a pair of rectangularpassages immediately adjacent the grain doors 10 when the latter are employed. On the sides of each of these passages guidel means are formed, preferably by securing angular bars 11 to the edges of car bottom 9 labout said passages.

Angular bars llvcarryinwardly projecting ltongue portions 11 forming rectangular flanges in the inner ysides of each of the pas,- sages. A gate'designated as' an entirety A normally closes each of the passages described and comprisesv an upper rectangular plate 12 and a lower rectangular plate 13 riveted or otherwise secured to plate 12 and provided at'its edges with downwardly and outwardly curvedpflanges 13, the edges of plate 12 and flanges 18at are spaced apart to .snuglydengage the tongues 11a on angle bars 11, whereby slidable engagement is made be tween gates A and guides 11. Angle bars 11 may be insetv slightly on the car bottom 9 whereby the top plate 12 of gates A may be maintained Hush with the upper surface of bottom 9. inasmuch as the passages are formed by recessing the side edges of the floor 9, it will be seen thatmy gates may be withdrawn outwardly ofthe car.

Secured to the bottom plate 13 of each of the gates is an inwardly extending armor link 11i preferably carrying at its inner end an eye 15, to which is secured one end of a coiled spring or other elastic member 16. Spring 16 may be secured at its other end to one of the central 'beams 7 thereby resiliently holding the gate in closed position. y An operating handle 17 .is secured by means of a chain or other flexible member 18 to the front end of each of the gates, facilitating the opening thereof from `without the car. Beneath and on the inner side of each of the passages described I provide a hood or delivery chute 19 of preferably segmental form, adapted to direct the grain )downwardly and outwardly and dropping rso description, butmayibe brieflyy summarized as'folloivs:

llVlienit :is-desired to unload the grain cai'. the handle1 lmaybe pulled, thereby permitting the'grainV in the central portion of the car ad'acent the Orain doorto be withdrawn. y r ,b 'm v Woor 'three minutes is 'sunici'ent time to yrenio've" a A"substantial"portion oir' the `'grain pressing against the grain door. The grain door may 'be 'thenH readily removed Without destro'yiii'gthe 'same as V'is the usual custom. After the grainadoors are removed the automaticshovels"may be employed 'and 'fthe car unloaded'in theusual manner.

2rEhe time factor in destroying the grain door is an importantfone, as vW'ell as the Waste and expense of providing new grain d'oforsf'tor every'sliipment. 'My device pei'- mitslthe' car'tobe rapidly unloaded Without impairingin any Way :thegrain doors Veinployed. i

As'has Vbeen stated, the grain delivered throughl'the hoods 19 is dropped at the side of the car and into the'usualfgrain.pits.

A'lt will benoted thatmy gates 'A eniploy'ed, overlap lthe tongues lla suliciently to Storm leak proofclosuresior thepassages and are moreover resiliently heldin closed position by thesprings 16.

Fromthefabove descriptionit Will be seen that I have'invented a highly efficient improvement'in box car construction, which may be readily applied as an attachment for standard box cars noiv inl use, and `which will accomplish results' heretofore runat tained.

' lt ivill, ot course, be understoodthat various changes maybe made iin the forni, details, arrangement and 'proportions of the parts, rWithout departing from the scope of applicaiits invention Which, generally stated, consists in a `device capable of carryway adapted to receive a grain door, said car -havingfa floor opening immediately adjacent said doorway, a delivery chute eX- ftending.downwardly and outwardly from said floor opening, a gate horizontally iiiovable. across .said opening and outwardly from the doorway of said .carimeansforiiormally holding' said .gate inwardly in closed ,position, and means yfor opening said-gate from ivithou .said car', .whereby:material in the car pressing: against the grainidoor maybe.
