GRAIN-CONDITIONEB.

Application filed June 9, 1913.

constructions and combinations hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is' an eleration and partial section of a machine embodying my invention, Fig. 2 is a vertical section through one of the tubes of the conditioner, Fig. 3 is a section through the centering cap at the upper portion of a conditioning tube, on a plane at right angles to the plane of Fig. 2, Fig. 4y is a longitudinal section on line 4--4 of Fig. 3.

I employin this machine a Vheating chamber consisting of a suitableV frame upon which is located a heater consisting of upper and lowerfheads 3, 3, tubes 4 passing through the heater and having their ends secured in said heads and a shell 5 preferablyv of cylindrical form into whichV the heads are set and secured, said shell being preferably surrounded by a suitable jacket 7 and heat retaining Vpacking 6. Steam is admitted to the heating chamber through a suitable pipe S and the water of condensation may be drawn off through a pipe 9.

The heating chamber as here shown is arranged upon a suitable plate lOhaving openings 11 located one below the end of each tube 4, and a regulating slide 12 is locatedy below the plate 10. A shallow chamber is preferably formed between the lower head 3 of the heating chamber and the plate 10. Above the heating chamber is a hopper 14 `which is preferably yieldingly supported and is connected with suitable means that controls the position of the slide 12.

In my application filed April 5, 1913,'Serial No. 759,137, I have illustrated and described the hopper herein shown and also the means for automatically controlling the Specification of Letters Patent.

Serial No. 772;652.

positionof the slide 12 rby the weight of the grain in the hopper, and while I have shown the parts in the drawings of this application.` I consider it unnecessary to describe the same herein.

rIhe tubes 4 each preferably project a short distancevbeyon'd the outer face of the upper head 3, and is surrounded by concrete (see Fig. 2). The lower ends of the tubes also extend beyond the outer face of the lower-head 3. Arranged in each tube 4 is a spirally coiled wire 16. rIhe diameter of this coil is preferably about one-half the diameter yof the tube, and the upper portion of the wire is of less diameter than the lower portion (see Fig. 2). At the lower end of each tube is a centering support consisting preferably of a casting having a flange orV Vring 17 that surrounds the projecting end of the tube 4, a central cross bar 18 and a projecting lug 19 having outwardly projecting bosses 20. At the top of each tube 4 is a similar centering cap having a ring 17, a cross bar 13, a lug 19 and projecting bosses y20. The bosses 2O on each lug are preferably arranged one slightly above the other as shown in Fig. 3 of the drawings so as to conform to the pitch of the spirally coiled wire. The lugs 19 are also provided with the projections V19', which bear 'against the inner circumference of the coil, and prevent any sidewise motion of said coil, thereby keeping the coil in the center of the tube. The ends of the spirally coiled wires 16 are engaged with the lugs 19 and bosses 2O by screwing said lugs and bosses into the end of the coil as clearly shown in Fig. 3 of the drawings. The rings 17 are brought over the projecting ends of the tubes 4 and the spirally coiled wire is thus centered in theV tube and is firmly held therein while there is upon each side of the cross bar 18 a substantially semi-circular opening nearly one-half the size of the area of the pipe through which the grain from the hopper above may flow freely into and through the tube 4.

I find that in operation the space within the spirally coiled wire will completely fill 'with grain and that this grain will remain therein without any substantial change as long as other grain is flowing through the tube, but when the flow of grain to the machine ceases the grain between the circumference of the coil and the inner wall of the tube Will irst run out and; then the grain Within the coil Will also run out.l I also ind that with. this'spira'lly coiled .core centrally arranged in the tube there is no danger of clogging the grain in the tube. Many of y the kernels of grain project throughY thev coil and it seemsimpossible for the grain t ov -arch over lor' bridge across between the coil and the inner Wall of the tube. This is probably due to the fact that these' project-r ing ends of the kernels of grainvvithin the spiral are also spira'lly arranged and the j kernels of grain do not lodge thereon but Vslide o and pass down the tube. It is also important, as I find from actual practice, to

. have the ends of the spiral centered and held many particulars Without departing from inyinvention.

y,I claim as my invention:-

1. The combination, in aY grainY heater,

vvithra heatingchamber, provided With heads and an inclrosing shell, ofV tubes extendingl through said heads, open' caps arranged on theirprojecting ends Voi, said tubes, andcores arranged in said tubes and consisting of spirally coiled Wires havving-their ends engaging said caps.

'2.y The combination, 1n a grain heater,

fWith a heating chamber, of heating tubes extending therethrough andY having ends 'projecting beyond the' Walls of said chamber, open caps fitting over the ends of said 2, I i Y 1,139,610

tubes, and' a spirally coiled Wire core in each Vtube having its ends engaging said caps.

3; Thev combination,- in. a grain heater,

With-azheating chamber, of tubes extendingy therethrough and having ends projecting beyond the Walls of said chamber, open ycaps each provided with a ring engaging the proc jecting end of a tube, and with av diametrically arrangedcross bar, and aninWardly projecting lug,A and a core formed of a spirally coiled Wire' arranged in each tube with its ends-engaging thelugs on said caps. l

4. The combination, in a grain heater, with a heating chamber, provided With heatinfg tubes, of a spirally coiled Wire core arranged in each tube, and an open cap atthe end ofeach tube, engaging the endsof said oore'andcentering the same in said tube.

5', vThe combination, in a grain heater,

with a heating chamber, of a tube extending ranged cros's bars k18 and the inwardly projecting lugs vl9fhaving lateral bosses 20, and

the spirally coiled Wire core arranged in saidk tube and having its ends engaging Said lugs and bosses.` Y Y In Witness whereof, I have hereunto set my hand this'25th day of March 1913.
