To @einem t may omwewi:

Be it known that doser-'ii Tour, a citizen of. the United o residing at Leavciiworth. in the county l'aeavenworth and State N' Kansas, have invented certain new' improvements in y@irain-Car A do declare the following to a l'uli, clear,and e; iet description of the invention., such as will enable others .skilled in the 'to which it apport-eins to mete and use the l inven4 on which relates to improveinents in Y n car doors has for its object to improve upon Ythe general construction oi? devi this class to snch extent as to provik compat tively simple yet highly eiiicieat door which may be easily operated.

l'lfith t in n certain nove in unirme coi ier tally e matter beng sup .i pleniented by 'the o pany/ing drawings whic constit ite part of this application and which;

.Figure l. is an elevation of the inner face o one o; iireroyed the sides ot a grain car with the f. isedg For. 2, is a similar rfi 1s.

e and en on 'the ectively by the lines 1L ot' F1'. 2; 5 is '1v door opened are vertical transvei planes d( isfnated r' 3--3 of l i n i an enlarg ide elevation or the carriage plate ar( )arts carried thereby, e portion of one ci' tli latches iountcd on said plate being` shown in section; Figs. 5 and I are `r`ertvbfal transverse sections taken on the planes indie d by t ie lines 6&6 and l-'i sectional ou the plar ated Ay the L: 5; Fig. 9 is detail longin 'vieiv as seen on the plane line 9 d of .lie't 8 isa l'iorizontal .tudinal se indicated i l is a pc i 1 of one of the drums which ass in raising; the door, and the operating springof said driungnand Fig. 'il is a detail horizontal sectional View taken on the plane indicated by line Lil-l1 of -n specifically describing the invention shown in the drawings above briefly described, similar reference characters will be placed on correspondiney respective indices. To this end, S refers 'to one of the upright sides of a common type of grain carLsaid side having; at its upper edge the usual longitudinally disposed beam B and being equipped with type of door iframe l?. of this class, the beam B is disposed on the interior thereof and serves as anchoring means for the sheathing of .the car.

Secured to the inner side of 'the beam B by any preferred means, is a pair of vertically spaced horizontal tracks l, said tracks being spaced inwardly from the beam by washers or the like 2. The tracks l receive 'therebetween a pair of grooved rollers 3 rotatably mounted on bolts or the like projecting rearwardly from an elongated horizontally disposed carriage plate 4, the flat sides of said pate being` positioned in upright planes. Riveted or otherwise secured to the upper corners of the plate i, is a pair of angular brackets or straps through W iose lower ends bolts 6 are passed horizontally, said bolts being' also passed through 'the ends oit horizontal shaft 7 spaced inwardly from the plate 4i..

Mounted rotatably on the opposite ends of the shaft 7 and having inwardly extending hubs S received snugly in the opposite ends of ay tube 9 which surrounds said shaft, isa pair of peripherally grooved drums 10,tho hubs of said drums being providerlwith eyes l confined Within the tube 9 and receiving the outer hooked ends of a pair of coil springs i2 also conlined in said tube and encircling the shaft. Theinnerends of the springs 12 are hooked into eyes 13 on a pair of collars ift which are slidably keyed on the aforesaid shaft. Thus, when the drums l0 are rotated, the two springs l2 will be placed under tension, this'being expedient for reasons to be hereinafter specified.

Partially Wound on the drums and depending therefrom. is a pair of cables 16 parts throughout the several views and reference will be herein made to the numerous any preferred*y As is usual with cars elements by their ybeing in the form of a sheet metal plate whose opposite ends are received slidably in upright angle-iron guides 19 when the door is closed, said guides being secured to the lower end of the frame F as shown. Hinged at its lower edge to the upper edge of the section 18 by any preferred style of hinges 20, is an upper door section 2,1" also in the form of a sheet metal plate, fthe section 2l. being preferably of less lengtli'than the section 13.

The upper corners of the Bloor section 21 are provided with laterallyiextending per-l forated ears 22 of appropriate formation contacting with other perforated ears 23 which extend laterally from' the sides of the frame F, bolts 24 being passed removably through the perforations in the ears 22 and 23 to hold the aforesaid section 21 against outward movement when' the door i's closed. However, when it is desired to open the door, the bolts 24 are removed, thereby allowing the section 21 to fold inwardly and downwardly on the section 18. The tension of the springs l2will now cause the cable 16 to be wound on the drums 10 as the door is raised. For holding the door in raised position, the two latches 25 are provided,

said latches being shown in the form of uprightflevers fulcrumed between their ends on th" bolts 6 and having said ends offset laterally, the lower ends of said levers being formed with hooks 26 adapted to engage notches 27 inthe upright edges of the section 18, near the upper end of said edges. In order to effectivelyguidathe section 18 and thus insure that the lwoks 26 properly engage the notches 27 ahdremain in engagemeni-l therewith as required, the levers 25 are provided with pairs 'of depending guide fingers 28 designed to receive the upper corners of the section ltherebetween and thus produce 'the results desired.

The upper ends of the levers 25 are pivoted to the outer ends of a pair of longitudinally disposed links 29 which are slidable through tubes 30 against the tension of springs 31 confined in said'tubes, the inner ends of the links 29 being provided with eyes to which a pair 'QLcables 32 are secured, said cables being extended from the eyes toward the center of the carriage .plate l and being here passed'over sheaves 33 and connected by a ring or the like 34. Thus, when a downward pull is exerted on said ring, the latching levers 25 will be so rocked as to release the door to allow the latter to be lowered.

The carriage plate 4 is normally held in the position shown in Fig. 1 by a horizonramasse Preferably used in conjunction with the parts above described, is some type of guide for receiving the lower edge of the door when opened, this guide being indicated in the present embodiment of the invention in the form of an angle metal bar 36.

A device 0i.l the class specified constructed as above described, will be found to possess a number of advantageous characteristics and to be highlyA eilicient in operation.

All parts are preferably manufactured as illustrated in the drawings, but yif found :v

expedient, numerous changes may be made within the scope of the invention as claimed..

l claim 1. The combination with the upright side of a grain car having thereina door frame, of a horizontal track at the upper end of said frame and extending laterally therefrom, a carriage mounted on said track and of a length a proximately equal to thel width of the rame, upright guides at the lower ends of the opposed sides of' the frame, a door mounted in said guides or vertical movement therefrom, winding means on the carriage, cables depending from said means and connected to the door, whereby the latter may be raised from its guides and a horizontal guide beneath the of a horizontal track at the upper end o' said frame and extending laterally therefrom, a carriage mounted on said track ,and of a length substantially equal to the width of the frame, upright guides extending along the lower ends of the opposed-sides of the frame, a lower door section mounted in said guides for vertical movement therefrom, an upper door section hinged at its lower vedge to the upper edge of saidlower section and adapted to fold, downwardly thereon, means for normally holding said upper section in upright position, winding means on the carriage, cables depending from said winding means and connectedto the lower door section whereby the entire door may be raised when the upper section is released and folded upon the lower, and
