To all whom may concern Be .it known thatI,"O

citizen of' the UnitedStates, residing at Halliday, in the county-of Dunn and State 5 of North Dakota, have inventedcertain new and useful lmprovements`'inv Grain-Spout Doors, of which the following''is a specifiv cation', reference being hadfto the accompanying drawings. 4This invention relates .to the grain spouts of elevators and likestructures, and particv ularlyl to means disposed in the length of the spout and adjacent 'its relatively small delivery end whereby access may be had to the interiorof the spout; f 1

In the grain spouts 'ofl,elevators as ordinarily constructed, there is' great trouble with the spout becoming clogged with stones, horseshoes, wooden blocks,`hay and straw,I and like foreign articles getting within'the spout at its lOlYI or discharge end and blocking the spout, these articles `not being able to lpass through the small Aend of the spout.- It .is very difficult-'to remove these articles 'and the only way it can be vdone in spouts as'- at'fpresent constructed is to remove they articlesthrough a hole in the bin to which the spoutis connected, fishing `for these articles'lhaving' tobe done through the entire length lof the spout. lThis ordinarily takes from thirty minutes7 toan A The general do away with'this inconvenience by .providing a'door disposed in the spout adjacent its narrow or delivery end, and further to so construct the door that' it will:` not impede the Vpassage of the material passing through the spout and will not be liable .to catch and retain any of this material.

A further object of the invention is the provision of a door having an improved l 45 form of latching device whereby the door is held in place, this latching device also constituting a handle for the door.

Other objects will appear in the course of l. the following description.

50, My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a grain l distributing spout provided with my nnproved of the spout, the door being also shown in section; Fig. 3 is a transverse secthrough this hole in -the b in downward object oflfiny invention is to door; Fig; 2 is a longitudinal sec-1 tional view of the spout, the door and the keeper being'alsoshown partly in sections Fig.' 4 is a lperspective detail view of the comb-ined latch and handle; Fig. 5r isl a per-A spective View ofthe door, detached.

- Patented July 18,1916.

Referring to these drawings, 10 designatesv a vspout leading from a bin 11. This spout as illustrated is rotatably connected with the b1n11 so that it may be rotated around its axis to discharge into Iany one of a number of hoppers leading toother chutes-or spouts lnfth'e manner common 1n grain elevators.'

A djacent its delivery end the spout is proi. vlded with an opening, designated 12, which' is relatively long and hasy a width v'eryj'v nearly equal the ldoor ofthe spout. This opening, however, may be made of any suit-` able length or width. Disposed uponl the, 1

exterior of the spout, at thesmaller end of and has its body outwardly displaced from ns the opening, is a keeper plate-13 which-is vriveted or otherwise attached to the spout the plane of the' face'of the spout so as to l form a pocket extending below the opening 12 and beyond the side walls of the opening. Disposed above the upper end, of fthe,

opening is a strapfll, forming a latch keeper. v v v The' door .consists of aplate 15 which is transversely curved .to itthe curvature of the spout, and which,rif the spout is tapered,

is likewisereduced in -width at its lower end,

the-lower extremity of vthis :door being.,y

adapted tobe inserted in the pocket-formed by the strap 14. Adjacent the upper edge' lof the door there is provided a guide strap 16. Mounted upon the door is the handle 17 which isjformed of astrip yof resilient metal riveted aty its lower end to thedoor,

as at 19, -and'having its' upperend extended v4through the strap 16 and normally extended v,beyond the upper edge ofthe door. v This re silient strip is preferablyv longitudinally 4slotted at 20 just above the intermediate .bowed portion. of the spring strip for the passage ofI a stud 21 which passesthrough the .strap 16. The resilient strip, as before stated, is bowed, this bowed portion extending between the strap 16 and the lower end of the strip. l i y Normally, and when the door is in place, the lower edge ofthe door is disposedin a pocket 13 and the upper'end of the resilient handle is disposed in the strap 14. When it is desired to remove the door, the spring handlevis compressed or; contracted, thus ,'Furtherniore, vit will be seen that the innerv lWithdrawing the latching end of the handle fromitsengagement with the strap 14 and the door then may be readily lifted out from the pocket. The door maybe as readily put in place and when in place will be rigidly held by the latching end of the handle.

lt will be seen that with this. construction it is" always easy to obtain' access to the lower end of the spout so Aas to remove therefromA any foreign artic-ies which -have lodged there,4 no matter how .large this may be.

aee of the spout is entirely 'smooth as the only .projections arenile heads ofthe rivets Winch vhold the straps in glace Wha@ i have aus-aerea a @wenn definite.

construction for this door which I'believe -to 'be particularly effective, it will ofcourse -be understood that the door may be varied in some respects Without departing from lthe, spirit of the invention and'that the latch# ing device ot the door may be changed. The: door is particularly adaptedto" the grain distributing spout ofl elevators though not 4necessarily limitedto this use.
