HEBER K. HANSEN, OF LOGAN, UTAH, ASSIGNOR OF ONE-FOURTH TO FEED TURNER AND ONE-FOURTH TO N. RALPH MOORE, or LOGAN, UTAH.

To all whom it may concern:

Be it known that 1, Hanna K. HANSEN, a citizen of the United States, residing at Logan, in the county oftache and State of Utah, have invented a new and useful Grain-Separator, of which the following is a specification.

This invention relates to means for separating grain and seed of different characters.

One of the principal objects is to provide a novel combination of elements, whereby a thorough preliminary separation of chaff, dust and the like from the grain or seed, a secondary separation of the different grades of seed, and the final separation of the heavier trash and different types of seed or grain are successively accomplished.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein v Figure 1 is a side elevation of the separator. Fig. 2 is a top lanview of the same. Fig. 3 is a longitudina sectional view therethrough. Fig. 4 is an end elevation of the lower portion of the machine, showing the means for shaking the shoe. Fig. 5 is a vertical sectional view on the line 55 of Fig. 8. Fig. 6 is a detail sectional view showing theinlet controlling gates for the fan. Fig. 7 is a detail view of the cont-rolling gate for the feed hopper.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a suitable frame is employed, comprising supporting standards 11, with longitudinal and transverse bars 12 fastened thereto. A feed hopper 13 is mounted on one of the upper corners of the frame, and preferably has a protecting screen'14 of comparatively large mesh arranged upon it, said screen permit ting the passage of grain and the like, but prohibiting the -introduetion of large bodies or articles, which may be mixed with the grain to be cleaned. In the present embodiment, the'screen 14, is shown as horizontally arranged, and it is evident that it may be located at an inclination, sothat" pass therethrough articles which will not will gravitate therefrom. The bottom of the hopper is provided with a discharge opening 14, controlled by a sliding gate 15, operating in grooves 16, and having a suitable handle 17. As shown in Fig. 7, the

gate 15, prior to its introduction into the grooves, is curved so that it will frictionally engage the walls of said grooves, and thus be maintained in any desired position without the necessity of fastening means.

'Arranged directly beneath the discharge opening 14, and supported in the frame, is a conduit that is in the form of a conducting hopper 17, having a comparatively large re-- ceiving mouth at its upper end and a smaller discharge ,opening 18. Disposed directly in rear of the conducting hop er 1.7 is another conduit 19, the front wa l thereof con stituting a portion of the rear wall of the ho per 17 The conduit 19 also has an upper receiving mouth, and furthermore is provided at its lower end with an offset discharge spout 20. A trap door 21, located in the bottom of the spout 20 atits junction with the main body of the conduit, is movable across the s )out, and thus provides an opening in said bottom, as will be evident by reference to Fig. 3.' The inlet mouths of the conduits '17 and 19 are disposed in spaced relatipn to the bottom of the feed hopper 13, and lunged on the rear Walls of said conduits are deflector leaves 32 and 23, the leaf 22 swinging across the said space, and being movable over the inlet mouth of the hopper 17, the leaf 23 in like manner moving across the space and being movable to a position to en tirely close the conduit 19. A fan casing 24 has a delivery throat 25 for directing a blast of air through the space between the conduits and feed ho iper, and said casing has inlets 2-1, controlled by sliding gates 25. These gates carry friction springs 26, one of which is shown in Fig. 6, said springs serving to hold the gates in different positions. In the casing is arranged a suitable rotary fan 26 carried on a shaft 27 that is journaled on certain of the side bars of the frame.

A shaking shoe is suspended from the suporting frame, and comprises an oblong rame 28,. suspended at an inclination by straps 29, the upper set of straps being held by fasteners 30 that permits the upper end of the shoe to be raised or lowered. This frame carries an upper comparatively coarse screen )late 31 that is fastened between upper and lower strips 32. The lower strips detachably fit within the fraine 28, the upper strips constituting flanges that prevent the material moving from the sides of the screen plate. This plate 31 has a lower imperforate apron frame, and projects some distance beyond the same, as shown in Fig. 3.

lletachablylocated within. the shoe frame is another frame 34, to whichissecured 'a novel separatingscreen 35. No claim 18 made herein to this screen, as the same constitutes the subject-matter of a divisional application liled on April 3, 1907, Serial No. 366,190. The said screen short of the lower end of the frame 28 to pro vide a discharge opening 39, and beneath. this opening is located a reversible delivery spout. The spout comprises side walls secured to the adjacent standards, and connected at their ends by end walls 41, the lower portions of the side walls projecting beneath the end walls ll, as shown at d2. The said side walls 40 have oppositely inclined sets of grooves 43 in their inner sides, and a removable bot tom plate 4.4 is slidable in either set of grooves, being preferably provided with ahandle 4-5, by means ol which it may be removed and inserted.

suitable manner, and terminates short of the above described delivery. spout. The shoe is actuated by a shaft a7,'journalcd, as shown at on certain of the standards 11., and having an, eccentric portion a9 that o )erates in boxings 50, secured to the end of the shoe frame Q8.

The machine can of course be either power ormanually operated. In the present emlhidiment, the same is to be run by hand. Therefore, a drive shaft 51 is journaled on the frame and projects beyond the sides there of, this shaft having pulleys 52 and 53 on its projecting portions. The pulley 52 is con nected to a pulley 54 on the fan shaft 27 by a belt 55 and the pulley 53 is connected to a pulle 5c on the shaking shaft 47 by a belt 57. The drive shaft 51 projects beyoni'l both pulleys and 5;}. and a handle crank is ar ranged to be attached to either end.

The operation of the machine may be briefly described as follows: The material to be cleaned and separated is introduced into the hopper l3, and. is fed therefrom at any desired rate, the flow being of course controlled by the gate 15. If now, the fan is in operation, it will be apparent that the blast therefrom will operate transversely of the stream of material, flowing from the discharge opening 14 of the hopperyand all cha'fr, dust, and the like will be blown from the rear of the machine. The heavier'grain and material Wlll enter the conduit or hopper .7, the same being controlled 1n a manner 35 terminates By this. arrangement, the bottom id can be located at an inclina- 33, which extends over the lower end of the well understood by the deflector leaf 22.

The lighter and less valuable grain'will be blown rearwardly and. enter theconduit 19, the size oi themouth of which is controlled. by the deflector leaf 23. The grain passing into the conduit 19, will .gravitatotherethrough and either be discharged through the spout 20 or through the opening controlled by the .trap 21. The heavier material and grain, however, which enters the hopper 17f will pass therefrom on to the shaklng shoe.

The large articles, such asunthreshed heads, sticks and the like, which have passed the screen 14,'will move downwardly over the- .screen 31,.and be delivered from theapron 33. The grain, however, willpass throughthe opening of the screen 31, andfa'll upon the screen 35. One classof the grain will not pass therethrough but thereover, and consequentiy will find its way into thedischarge spout 40. The -'material, which does "pass t irough-said screen 35, will be moveddownwardly upon the grain pan. 46, and drop-from the end of the same. As a result, it will be seen that there are six distinct separations in this very simplestructure, so that the grain will not only be cleaned, but effectively separated. Horeover by reversing the chutebottom and securing the handle crank on the opposite side of theshaft 51, the machine can be operated from the'opposite side. Moreover, the structure as a whole is open to change and modification within the scope-of the claims hereto appended, and is not lim ited to the exact details and arrangement shown.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is V 1. In a separator of the character described, the combination with a supporting frame, of a feed hopper mounted thereon and having a lower disciarge opening, a gate for controlling the discharge opening, conduits having upper receiving mouths locatedbeneath and in spaced relation to the feed hopper, one of said conduits extending below the other and having an offset delivery spout, deflector leaves pivoted on the upper ends of the rear walls of the conduits, a fan casing having a delivery throat communicating with the space between the feed hopper and" beneath the shorter conduit, the other conduit extending below the upper end of the screen, and means for rotating the fan'and shaking the screen.

2. In a separator of the character described, the combination with feeding means,

of the screen "and comprisinr side walls.and

vo'fa'fan, ascreenithat receives the material,

j ecting portions of such side walls, and a detachable bottom that fits in either set of grooves and extends the length of the spout.

3. In 'a separator of the charaeter described, the combination with a supporting-- frame, of a feed hopper mounted thereon and hav ng a lower discharge opening, conduits having upper receiving mouths located side by side beneath and in spaced relation to the feed hopper, one of said conduits extending below the other and having an offset delivery spout,.deflector leaves arranged between the receiving mouths of the conduits and the discharge opening of the feed hopper, a fan for delivering a blast of air between the feed hoppers and, oonduit s, a shaking screen supported at an, inclination on the frame and aving itsupper end disposed beneath the shorter conduit and above the offset delivery end of thelonger conduit, and means for rotating the fan and shaking screen.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
