I l a AUMTED STATES PATENT OFFICE.:
'CHARLES Lf GEBHARDT, OF GBEEN, KANSAS.
anAIN-sAvncf` A'rTAonMnNr ron. rHRnsErNG-MACHINESL To aZZfwLomz't may concern:
Be it known that I, CHARLES L. GEB- HARDT, a citizen of the United States, residing at Green, in the county ofl Clay and State of Kansas, have'invented certain new and useful Improvements in Grain-Saving Attachments for Threshing-Machines, of which the following is a specification, reference being had to the accompanying drawings, which form a part hereof.
My invention relates to improvements in devices for the saving of grain in the process of threshing and the object of my improvements is to provide an attachment for threshing machines of the ordinary type by means of which the grain is more completely separated from the chaff and returned to the machine.
I attain this object by means of the construction hereinafter described and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation in perspective of a grain thresher with my device attached;
Fig. 2, a sectional side elevation of that portion of a thresher to which my device is attached with a portion of my supplemental elevator boxing broken away;
Fig. 3, a detail view of the mechanism of my invention with a section of the sieve broken away; and
Fig. 4, a vertical sectional view through the line mof Fig. 3, of my invention as attached to the main thresher.
Similar reference numerals indicate like parts throughout the several views.
1 refers to the main frame of the thresher to which my device is attached; 2, the elevator frame; 3, the fan-blades; 4, fan-pulley; 5, fan-shaft; 6, tilting wind-board; 7, windboard tilting adjustment; 8, grain-auger; 9, sprocket operating such auger; 10, sprocket attached to fan-shaft; 11, sprocket on opposite end of shaft 26; 12, sprocket attached to elevator shaft; 13, fan-door; 14, grain sieve; 15, grain-pan, its bottom sloping toward the auger 8; 16, chaff-auger to remove the waste from behind the fan-drum (this auger is unnecessary in the type of thresher in which the blower may be placed on the outside of the machine) 17, sprocket operating such auger; 18, power sprocket connected by chain 19 with sprocket 17; 20, chain connecting sprockets 9 and 10; 21, chain con- MSpecification of 1'..etters,Pate-nt.v Patented J une 28, 1921,

My device is bolted to frame 1 so that the sieve 14, which is agitated by the threshershoe 29, receives the chaff or tailings from the tail-board of the shoe. The frame 33 of the sieve 14 extends rearward from and is attached to the rear of the tail-board-of-theshoe 31 of the main machine by means of angle-irons secured to such thresher-shoe, one on each side, in which frame 33 rests and to which such angle-irons are secured. As such shoe is agitated in the process of threshing such sieve is also shaken. From this chaff or waste the grain is separated by the blast from the fan 3 and falls to the grain-pan 15 and thence to the grain auger 8 by which it is conveyed to the tailings elevator by means of the supplemental elevator 2. It is operated by means of belt and pulley connected with the fanning-mill shaft of the thresher or other convenient power shaft.
The fan 3 extends across the thresher and the wind-board 6 at the mouth of the blast channel is adjusted by any ordinary appliance for that purpose to provide such a size opening as the weight or density of the waste material may require. Such fan is operated by means of a belt, from any convenient power, attached to pulley 4 and from the opposite end of shaft 5 a sprocket chain 2O connects sprocket-wheel 10 with sprocket-wheel 9, which in turn operates grain auger 8, from which the power is transmitted to sprocket-wheel 11 connected by sprocketchain 21 with sprocket-wheel 12 operating the elevator cups 24 by means of sprocketchain 23 and discharging the cleaned or separated grain through spout 27 into the tailings elevator of the thresher.
In the ordinary process of threshing the unthreshed grain or rather the straw with the grain in the heads is thrown into the feeder, from thence carried to the cylinder where much of the grain is separated from theoheads and passes thence with the straw f passes on over` the end of. thechaier, and' or chaff containing much unseparated grain,
particularly when the machine is overfed,
it is ,these tailings or waste, just before being caught by the blast from the stackerfan, that my device catches, separates and carries to the. tailings elevator, thereby saving the grain which would otherwise have passed out with the straw to the strawstac ters-Patent is,-
Having thus described my invention what I claim as new and desire to secure by Let- The combination Vwith a threshing machine provided with a shoe having a tailboard, of a sieve .attached to the rear of such tail-board and extending rearward therefrom and agitated bythe movement of such shoe, such sieve bein@r Yso disposed as to receive the tailings directly from suchtailboard, a supplemental fan so disposed as to create an air blast upwardly through such sieve, and means for conveying` the gralnto a predeterminedv oint.
