To all whom it may concern:

Be it known that I, DAwsoN W. Dunna'r'r, a citizen of the United States, and a resident of Clarksville., county of Montgomery, State of Tennessee, have invented certain new and useful Improvements in Grain-Scourers, of which the following is a full and clear speciiication, reference being had to the accompanying drawings, in which- Figure 1 is a vertical longitudinal sectional view of a machine embodyin the essential features of my invention; ig. 2 a side elevation in detail of the automatic moistener; and Fig. 3 a detail perspective view of the automatic scouring or peeling devices, the parts being separated for the purpose of better illustration.

rlhe object of this invention is to provide a simply constructed apparatus for automatically` moistening and scouring or peelmg grain, and the invention consists of certam .novel Jfeatures of construction hereinafter described and claimed. In the drawing a designates a spout or hopper adapted to conduct the grain into one end of the top conveyer tube rThe ther or tail end of the tube h discharges i into an inclined tube c which in turn dist charges into a second eonveyer tube ci ar- 30 ranged belowtube lb, The other end of the tube a? discharges by means 'of an inclined tube c into the forward end of still another conveyer tube and the tail end of this latter tube discharges into a spout 'g from ducted to a suitable A rotary conve er in each one of the I conveyer tubes i: es to forcibly move the v i' in along .the same, these screw conveyers 40 eing driven .in the direction of the arrows any suitable mechanism. ln-the spout a isa depending valve plate i whose shaft is` l extended throuh the side w of the spout and is wei hte atj to cause the valve to normallyy oseu Attached tc-one end of the shaft of this valve' .is an armjc, the free end orf-this arm being connected by `means of a linka? te a sliding'rod m, the outer end cf this ,rodlm carrying a funnel shaped tube n.

A water tank 0 supplies water to this funnel through.v a suitable valved pipieg p.

- The funnel is ada ted to charge either into a passage g'lea ing into the upper conveyer tube or into the inletend cfa waste e r. When no grain is passie through the spout the valve plate i 1s held c osed andv i A Specication of Letters Patent. Application led March 11,- 1912. Serial, No. 688,009;

retenues Nev. se, taie'.

with a waste pipe 1' so that the water which drips from the water supply means will run olf into the waste pipe; but as soon as the grain begins to flow down through the spout the valve plate will be shifted, the weight j will be raised and the funnel will be pushed back until its outlet is coincident with the passage g, so that thereafter the water will be discharged into the upper conveyer tube. ln this'way I provide a simple automatic mechanism which will cut off the supply of water as soon as the supply oi grain to the upper conveyer ceases, thereby avoiding the necessity of manually cutting olf the water every time there is an. intermission in the supply of grain.

, is construction is advantageousl for the further reason that it avoids the use of means for automatically opening and closing the valve in the supply pipe'p, 1t being simp'ly necessary to roperly adjust the valve at vthe `beginning o the operation'o the machine, and thereafter the feed will be uniform. sight-feed for the water since at all times the dropping of the water from the end of pipe p may be observed.

ln the tail or discharge end of each Vof the conveyer -tubes is lmounted a metal open ended tube s into which the end of the conveyer extends. The outer or discharge end of this tube s 's normally closed by a disk t which may be constructed of some rigid material as metal or of some exible or yielding rllhis construction also provides a the funnel is normally in communication material such as stiff leather or rubber.

This disk fits squarely against the outlet end of thetube and normally completely closes the same, it being pressed to its seat on the end of the tube by a coil sprin u whose outer end bears against a pressure ar v suported on rods fw, suitable thumb screws w Being threaded von the ends of the rods for the purpose of varying the action of the s rin on the disk. With a construction of t is c aracter it will be observed that the Ascrew conveyerwill forcibly ress the grain against the disk and this w' ll result in the disk moving away from the end of the tube far enough to permit discharge 'of the gram. The grain will be forcibly pressed out and the friction between the `face of the disk and the annular edge of the tube a will be sufcient to clean and scour or peel the grain, the pressure being regulated to suit the exigencies of the case and the number of conveyer veyer tube and employing the shaft of the conveyerto assist 1n supporting the adjustmg means, it will be seenvthat I provide means whereby the attendant may readily have access at all times to the parts in order that the pressure of the disks may be nicely regulated. f

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is- 4 l. A grain scourer consisting of a conveyer tube, a screw conveyer therein yhaving its shaft extending beyond the end of said tube, a scouring disk adapted to close the end of said tube and being mounted slidably on the extended end of the conveyer shaft, a

spring on the extended end of the conveyer shaft, and means mounted on the conveyer tube and said shaft for varying the pressure ofsaid spring on said disk.

2. A grain scouring means consisting of a conveyer tube, a screw conveyer therein having its shaft extending beyond the end of the tube, a scouring dis adapted to close the end of the tube and mounted on the conveyer shai't9 a pressure bar slidably mounted on said shaft, a spring between said pressure bar and the disk, and adjusting means for the pressure bar supported on the conveyer tube, for the purposes set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
