Application ined July 24,

' the railway carl door outwardly of the ordinary graincar ydoor to hold'the grain while permltting removal of the sections of the nia-1n grain door without the necessity of destroying the same.

An'important object of the invention is to produce a device which is capable of usewith various types `of grain car doors without re* v"gard tothe distance between the door posts between, certain limits and which may be very readily inserted and removedp A further object of the invention is to provide an extensible door having means whereby it may be securely held in its closed position without regard to the extent to' which itv is expanded. f y A still .further ,object of the invention is the'production of anextensible door of this character which may be readily and cheaply manufactured, which will be durable and etlicient in service andfa general improvement intheart. i .l

Y These and other'objects l attain by the constructionshown in the accompanying draw' ings, wherein for thepurpose of illust-ration( vention vand whereinz-f Figure 1 is a frontelevation of a temporary grain car door constructedin accordance with my invention;

' galvanizedy tin 4ofabout twenty'gauge having secured thereto 'atvthe edges thereof andat its'center tubular reinforcing'bars Atene edgeof the sheet, these reinforcing bars-and V 4 thersheet 12 are secured to one flange 14 of the vertical angle bar, the other ange 16 of a section on the line2`2 of Fig-V 'i and 16 immediately above the central'bar 29 1928 Serial No. 294,983.

which has'directed therethrough 'set-screws 17, the purpose of which will presentlyappear. lThe upper and vlower tubular bars 13 are preferably'connected to this angle bar by angular braces, designated at 18. Adjacent the opposite edge of the sheet, the tubular bars are connected by spaced vertical braces 19, each of which is in the form of' a piece ofk strap iron bent to form a loop through which the upper and lower, tubular 'bars are passed. These braces about midway the height thereof are connected by a transverse bracket 20 from which extends outwardly a pivot bracket 21, to which is pivoted a lever 22 having adja cent its pivot a plurality of lopenings 23. The outer end'of this lever isformed-as a handle 24, by means of which'it may be manipulated.

Theauxiliary section 11 comprises a sheet 25 similar to the sheet 12, to the outer edge l of which isse'cured one flange 26 of anangle bar 27, the other flange of which has set-- vscrews 28 directed therethrough'. `To this angle bar fare secured the ends lofqrods` 29 corresponding in. number and'arrangement' to the tubular bars 13. The upper `andlower rods'are braced by angular braces 30, the

innerends of ywhich engage therods and are secured thereto and tothe sheet. These braces are inserted between the rods and the f sheet, so that the surface of the sheet is spaced fromthe face of the'rods. The sheet slidably'engaged in the tubular bars V13.

rPivotally connected to the angle bars `2"? Y and the central tubular rod 13 are the ends of toggle links 31, the inner ends of which are pivotally connectedA to one another, as at 32.v These links extend' through `and voperate in the slots 33'formed between adjacent runsv v chain V34., The opposite end of'this chain is lconnected to one end of a tension spring mechanism 35, the opposite endofrvwhich is in turn connected to a hook element36-`adapt`' ed to be selectively engaged 1n an -opemngf 23 of thelever 22. Y. Y -k Y ,y

It will be noted that the pivotal connection of thelever 22 offset 'outwardlyfrom` the face of the sheet-12 as respectsthe hook 36 to'which the chain is adapted for connection,

so that if the connection between the hookk 36 and lever 22 is under strain when the lever is vertically disposed andlies against the face of the sheet, this strain will tend to move the lever toward the sheet which, of c0 urse,`acts as a check for its motion, so that theV strain is held.

It will also be obvious that a downward strain ofthe pivotal connection between the toggle links will tend lto urge Vthe auxiliary.

section 11 outwardly, so that if the device is arranged between door posts,this vstrain will .forcethe angle bars into engagement with the doorposts and maintain the door 'in position therein. The set-screws will assist in prefventing side slip of the door when applied.

VIn inserting the door, the toggle links are -preferablypulled downward until the door is ,firmly engaged after which the lever may be elevated and the connection of the -chain 34 with ythe/.hook 33a altered, so that when vthe lever is again forced downwardly to its vertical position, the full strain of the spring 35 will be acting upon the toggle links to urge them into alignment with one another andac- V.cordingly acting to spread the sections of the doorandcause a tighter fit between the angle irons and the door posts P of the car. The sheet 12 adjacent its bottom andpreferably between the vertical braces 19 is formed with an opening 37 and a detachable spout 38 is preferably provided for engagement with theedges -of these openings. In the present construction, this spout is shown with a curved lipr39 upon the lower wall40 adapted to engageover thelower edge ofthe opening l and theupper-wall 41 of the spout and sheet 10 areshown as provided withcoacting faswteners 42 for holding the upper end of the spout in engagement.

To further assist in maintaining the y'sheets l12 andg25 in proper engagement with one another, the sheet 12 has preferably. secured to the rear face. thereof, as designated at 43,

' lbars which `slidably engage the rear face of the sheet 25. The sheet 25 hassecured there- -to guides 44 through which these bars are slidably directed. Y

v very readily inserted 4and when it is in .posi-k It will be obvious that with a construction` of this character, the auxiliary door may be iti'on, the maingrain door can be removed a section Vat a time without ,destroying the boards 'from which it is formed.

f It Vwill also be obvious that the construction Y f' hereinbefor'e set forthis vcapable of a ,certain yfrange of Xchange and modification, without i lmaterially departing from the spirit ofthe Y invention and I accordingly do not limitmysel-f to such specific structure except as here-k v inafterv claimed.
