PORTABLE nnnvn'ron.

. I Application filed February 10, .1910. Serial No. 543,021.

To all whom 'it may concern: Be it known that we, EMIL A.'Fnrrz and HUGH J. CARSON, citizens of the United States, residing at Fairfax, in the county of Renville and State of Minnesota, have invented certain new and useful Improvements in Portable Elevators; and we do hereby declare the following to be a full,-

of the novel' devices and combinations of do viceshereinafter described, and defined in the claim.

In the accompanying drawings which illustrate the invention, like characters indihout the several views.

cate like parts throu Referrmg to the, rawings, Figure '1 is a longitudinal vertical" section taken on the line 02 a? of Fig. 2; and Fig. 2 is an end elevation, with some parts sectioned, on the line m w of Fig. 1.

The numeral 1 indicates a portable skeleton frame upon which is mounted a hopper 2. This hopper is provided, in its vertical side, adjacent to the bottom thereof, with a short dischar the eye4 of a an case 5 secured to t e frame.

Mounted in suitable bearings 6 on the frame 1 is a horizontally extended shaft 7., the inner end of which projects into the fan case 5. To the lnner end of the shaft 7, is

rigidlysecured a disk-like head 8 which works close to the inner surface of the outside of the case 5 and on the-op osite side from the eye 4.- On the inner ace of the head 8 is,secured a. multiplicity of radially and laterally projecting blades v9. These blades are preferably, as shown, channelshaped in cross section, ,with one side of each blade 9 riveted or otherwise secured to the inner-face of the head 8 and with the other side thereof working close to the inner wall of the fan case 5. By reference to Fig. 2, it will benoted that'the inner ends of the radially projectin blades 9 terminate from the center of the an case 5 a distance equal to the diameter of the eye 4 of the fan case 5, thus permitting the blades 9 to rotate e neck 3 which pro'ects into- 7 around the inwardly projecting end of the discharge neck 3. v

The fan case 5 is provided. with a longitudinal opening 10 which leads to an up wardly projecting spout 11. To the free uper end of the spout 11 is secured a flexible ischarge nozzle 12 which may be of any suitable construction. In actual practice, suitable means will be provided for operating the flexible nozzle from a distant point.

" Mounted in the discharge neck 3 is a vertically movable gate 13 having an upwardly extended stem 14 which terminates at its free upper end in a hand piece 15. guides 16 are secured to the hopper 2 through which the stem 14 works. To the outer end of theshaft 7 'is secured a driving pulley 17 which may be driven from any suitable sourcer The operation of the device may be briefly stated as follows: The fan is first started and when the same has reached the required speed, the grain to be elevated is'poured or.

Suitable shoveled into the hopper 2 and permitted to flow through the discharge neck 3 and into the 'fan case 5. By the adjustment of the gate 13, the flow of the grain through the discharge grain, in leaving the discharge spout 3, will first strike the head 8, be caught by the blades 9 and thrown through the opening 10.

in the fan case 5 into the discharge spout 11.

From'thence the grain vwill be blown throu h,

the spout 11, by the blast of the fan. y the proper adjustment of the nozzle 12, the grain may be deposited into any one of the several bins of the granarliy, at will.

The above device, wh' every simple and of comparatively small cost, has, in actual practice, been found highly efiicient for the purposes had in'view. It has been found that any smut I will be broken up by the action of the blades 9 on the grain, and it has also been found that a great deal of the dust in the ain will be blown therefrom as the grain eaves the 'dischar e nozzle 12.

What we claim is: L In an elevator of'the kind described, the combination with a fan casing having an eye -in oneside and provided with a discharge spout, of a disk-like head within said fan casing and working close to the opposite side from said eye, inwardly and radially proj ecting channel shaped blades secured to said neck '3 may be regulated. The

which may be on the grain head, a driven shaft projecting into said fan In testimony whereof we aflix our signacasing and secured to said head, a hopper tures 1n presence of two witnesses.

having a discharge neck projecting into and EMIL A. FRITZ. through the eye of said fan casing, and a HUGH J. CARSON. regulating gate mounted in said dischar e Witnesses:
