ih all whom may concern:-

lznown that 1, Hum: J, Causes, a is vecu of the Unitcd States, residing at llairfam in the county of llenvil-le and State oi lvl'innesot'a; have invented. certain nev and useful Improvements in l rtable Elevoters; and I do hejrel'iy declare the follow to bee full, clear, and exact description of the invention, such as will enable others 1 lled in the art to which it uppertaius to e and use The same.

in invention has for its object to prole a SQlil-CfJZ1ifllZlQfl and portable grain eleespecially adapl ed for use on farms, liveriug grain into grammes; and, to shis end, the invention consists of the novel do does and combinations of devices heroindelined anddescrihed in the claims. in the accompanying drawings, which illustrate the invention, like characters indicate like parts;throughout the several views,

Referring to she drawings :---Figure 1 is a viewspducipally in longitudinal vertical lion taken centrally ihrough the loved lion; $2 is an end "elevation With the feed spout swung into an inoperative position; Fig, 8 is a side elevation of the parts shown in Fig. 1 with some parts broken away and with some of the exposed parts shown in section; Fig. i is a vertical section lakes on the line of 213 of Fig. 8; and Fi F; is :1 detail View in vertical section taken collie line m of Fig. 3.

The numeral l indicates a supporting hose on which is mounted a fan casing 8,

shown, preferably composed of two upright sections detachably scoured one to tho oilier, and, having formed therein axially alined eyes 10 and 11. Each section of said casingis provided with a supporting foot 5 rigidly secured to the supporting base' l. is. lzwo-part liorizonljally extended bearing sleeve '12, axially alioed with the eyes 10 and 11, is secured to the lower section of she fan casiug 8 by a bracket 13, integrally formed therewith oil the same side as the eye '10. lntermediately journaled in the hearing sleeve 12 a shaft 14, the inner end of which extends through the eye '10 into lhefan casing 8, and the other end of which rigidly secured therein adriviug pulley 15.

her 17 and a plurilty of radial hollow blades 18 leading from said chamber, the said hollow blades 18 having fiat driving faces. The side of the fan chamber 16, adjacent to the eye 1.0, has integrally formed therewith a horizontally extended hub 20 lieyed to the inner end of the shaft 14. The other side of the fan chamber 17 is provided with on eye or an air and grain intake 21 surrounded by a laterally projectlug flange 22, which extends through and Works wieliin the eye 11 of the fun casing 8. Preferably, a gas engine is employed for driving the fan 16, in which case a belt will be arranged to run over a pulley on the engine shaft and over the pulley 15, but, for the purpose of this case, it is not thought necessary to illustrate either the 19, provided for preventing the air and grain from passing between the ends of the fan blades 18 and the casing, after said blades have passed the opening 23. This cut-ofi blade 19 is heldin different vertical adjustment by a set bolt 19, in order that the same may be adjusted from time to time, to take up wear on the ends of the A discharge grain spout 25, preferably made in two sections, dctachably connected at 26 by a bayonet joint or other suitable means, not shown, is, at its lower end, connected to the casing 8 by a flexible joint 27. This joint made up of pivotally connected members of well-known constructiomwthe lower of which is telescoped onto, the collar 24. The members of the flexible joint 27 are preferably made rectangular iii with the joint 27 by a long coiled spring.

29, anchored to said plate, and to the supporting base 4. Obviously, this spring Will permit the plate 28 to move during the adjustment of the joint 27. Any suitable means, not shown, may he provided for supporting the upper end of the discharge spout 25.

A pair of alined vertically spaced hinge lugs 37 are integrally formed with the section of.the fan casing 8 having the eye 11. One end of a supporting arm 38 is pivoted to the lower hinge lug 37 for horizontal swinging movement. The inner end of a horizontally extended feed spout 39 is supported on the arm 38, by a pair of legs 40, for horizontal swinging movement' therewith. A V-shaped brace rod 41 is provided for holding the arm 38 from sagging. The upper end of this rod 41 is pivoted, at 42, to the upper hinge lug 37, and the lower end thereof is rigidly secured to the arm 38." .At its intermediate portion, the rod 41 is rigidly secured to, the upper end of the inner leg 40. On the outer end portion of the feed spout 39 is a longitudinally extended open bottom hopper 42 arranged to discharge into the said feed spoilt and a ground-engaging leg 43. As shown in Fig. 1. the feed spout ilSJ-is supported by the leg 43 in a position to permit the hopper 42 to swing under the rear end of the wagon box, and into a position to receive the grain dumped or shoveled from said wagon'box, after the end gate thereof has been removed or opened.

The grain delivered into the spout 39 is carried to the fan 16 by a. spiral convcyer 45. mounted in the feed spout 39, with one end of its shaft journaled in a bearing 46 on the outer end of said spout, and in a bearing bracket 47 suspended within the inner end portion of said spout. On the inner end of the convcycr sha ftis a head 48 having :1 rectangular socket, the purpose of which will presently appear.

The conveyor 45 is driven from the shaft I 14 by the following connections. to wit Keyed to the shaft 14 a relatively small grooved friction wheel 49, which meshes with a relatively large beveled friction wheel 50. keyed to one end-of a countcr-sh'aft 51 journaled in bearings 52 on the. fan casing 8. [To the other end'of thecounter-shaft 51 is keyed a sprocket wheel 53, over which sprocket wheel and an alined sprocket wheel- The sprockct' 54 runs a sprocket chain 55. wheel 54 is keyed to a short shaft 5(i, alined with the shaft of theronveyer 45.,and journaled on a bearing bracket formed with the fan casing 54. On the end of the shaft 56, adjacent to the conveyor 45, is a rectangular head 58 adapted to fit within the socket of the head 48 when the con veyer spout 39 is swung into an operative position. and thereby lock the conveyor and shaft 56 for common rotary movement. Obviously, when the spout 39 is swung intoan inoperativeposition. the driving connection between the shaft of the conveyor 45 and the shaft. 56 is broken, by the separation of the interlocking heads 48 and 58.

To regulate the flow of grain from the 57 integrally maybe varied; and said hood and hopper cooperate to afford a feed regulator, to determine the amount of grain to be fed to the conveyer 45 from said hopper. The upper ends of the arms 60 are, as shown, bent laterally outward to afford hand pieces by which the hood 59 may be raised or lowered within the hopper. I

The operation of the device maybebriefly stated as follows :When the device is not in use, the feed spout39 is swung to one side on the arm 38, so that a wagon may be driven close to the supporting base 4. The feed spout 39 is then swung into an operative position with the hopper 42 slightly under the rear end portion of the wagon box, in a position to receive the grain as the same is shovcled or dumped from said wagon. The fan is now started and, when the same has reached the required speed. the end gate of thewagon is opened and the grain allowed to llow into the hopper 42, and directly onto the hood 59, and is fed therebetween and the upwardly diverging sides of the hopper 42.

-into the feed spout 39. Obviously, by vertically adjusting the hood 59, the amount of grain fed to the conveyer 45 may be varied atwill. From the spout 39, the grain is through the eye 11 over the grain in the spout 39. By the proper adjustment-of the delivery spout 2). the grain may be deposited in the granary where desired.

\Vhat I claim is: y
