The invention also has for an object to provide a novel and improved machine of this general character of a portable type and wherein a conveying mechanism is employed for carrying the bundles or sheaves to the threshing cylinder and wherein means is provided for lifting into proper engagement with the conveyer mechanism a sheaf or bundle which may be lying upon the ground.

The invention also has for an object to provide a novel'and improved machine of this character wherein the same is power operated and'whereby the engine may be employed to drive the machine over the surface and also to operate the various movable parts employed. in. the threshing or other operations.

It is also an object of the invention to provide a machine of this general character with a novel and improved grain separating means which includes a revolving drum or cylinder into which the threshing cylinder discharges together with means positioned within said revolving drum on cylinder for separating the grain.

The invention has for a still further object to provide a novel and improved grain separating means wherein a conveyer is positioned within a revolving cylinder or drum and upon which the grain separatedby the drum is discharged and wherein said conveyer discharges upon a screening element also disposed Within therevolving cylinder 01' drum.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved threshing machine whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwlse more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the I better understood, 1 will now proceed to de- 7 scribe the same with reference to the accompanying drawings, wherein Figure 1 is-a'view in side elevation of a threshing machine constructed in accordance with an embodiment of myinvention; Fig. 2 is a longitudinal vertical sectlonat view taken through the machine as herein embodied, certain of the endless aprons or conveyers being shown in elevation;

Fig. 3 is a view partly in top plan and.

partlyin horizontal section of the machine as herein set forth;

Fig. 4: is an enlarged transverse sectional view taken through the grain separating means and the adjacent portion of the machine; and

Fig. 5 is a fragmentary view in perspective of the lifting member as herein disclosed.

As disclosed in the accompanying drawings, F denotes a frame of predetermined dimensions and configuration and which is supported by the wheels W. The rear wheels W are adapted to rotate With their axle or shaft 1.

The axle or shaft 1 is provided with a gear 2 in mesh with the gear 3 loosely mounted upon the transmission shaft T driven by the engine E. The engine E may be of any preferred type but preferably internal combustion.

Coacting with the gear 3 is a clutch member 4t keyed to the shaft T but capable of movement longitudinally thereof whereb the gear 3 may be caused to rotate with the shaft T as desired or vice versa. As the clutch member at may be moved in any manner which best meets the requirements of practice, it is thought that a detail description and illustration of such operatingmeans is unnecessary. 1

Mounted upon the frame F is the housing or superstructure H and which has rotatably supported between its side walls the threshing cylinder A of a conventional type and which coacts with the concave B.

The axle 5 of the cylinder it extends be- 6G ing or'superstructurej H and said extended and 18 which serve to facilitate the delivery of the straw to the cylinder A. r V

v Discharging between/the rollers 17 and 18 is a chute 19 through which the grain and straw falls a ter the bundles or sheaves have yond one side of the housing or superstruc ture H andthe extended portion thereof is provided with a pulley 6 around which is disposed a belt 7 which is also directed around a pulley 8 fixedto the shaft 9. The shaft 9 extends transversely of the frame F at a predetermined position below the cylinder A and has atiixed thereto the gear wheel 10 in mesh with the gear wheel 11 carried by the vertically disposed shaft 12 operatively supported in any desired manner by the frame 1 and .the housing or superstructure 'H.

The lower end of the shaft 12 is provided cwith the gear 14 in mesh with'the gear 15 loosely mounted on the transmission shaft T y and with which coacts a clutch member 16 keyed to said shaft T but capable of movement longitudinally thereof whereby the shaft .12 maybe caused to operatewhen desired. The manner of operating the clutch 16 forms no particularpart of my invention and as any well known structure may be employed, it is thought that a detail description and illustration thereof is unnecessary.

Inadvance of the threshing cylinder A are the vertically spaced feeding rollers 17 been severed by the cutters 20. V

21 and 22 denote coacting endless conveyers disposed on predetermined inclines, the upper conveyer 22 being operatively engaged with the shafts 23 rotatably supported by the side boards 24: whilethe lower conve 'er a ll 21 isoperativelyengaged with the shafts 25 rotatablysupported by the side boards 26.

by it will be perceived that said in the same general direction.

The lower shaft 23 of the upper conveyer 22 and the upper shaft 25 of the lower conveyer perceived that the lower feeding roller 17 and the conveyers 21 and 22 will be caused to properly operate.

Thecutters 20 are mounted upon a shaft 33 which extends beyond a sideof the housportion is provided with a pulley 34 around which is disposed a belt 35 which is directed underand in contact with a pulley 36 carried by anextended portion of the shaft 37 of the forwardly directed tines 4-1.

the clutch member 49 keyed to said of the housing or superstructure H for a purpose'which will hereinafter be more particularly referred to.

Interposed between the lower ends of the side boards 26 is a bar 40 provided with the The tines 41 are adapted to substantially contact with the ground or. surface over which the machine travels so as to raise the sheaves or bundles which may be lying upon said ground. or surface so as to be properly engaged with the conveyer 21.

cylinder or drum C is adapted to rotate, and

as herein disclosed, the opposite A end portions of said cylmder or drum C extend within cylindrical openings 44 produced in the transversely disposed walls 4-5 included in the housing or superstructure H, and coacting with said cylinder C and wall 4-5 are the anti-friction members 46 whereby it will be perceived that said cylinder or drum C may be caused to rotate with a minimum of frictional resistance. Disposed around the cylinder or drum C 1s a drive belt 47 which is also disposed around a pulley 48 loosely mounted upon the transmission shaft T and with which coacts shaft T but capable of movement longitudinally thereof, whereby the rotation of the cylinder or drum C may be readily controlled. The clutch member 49 is adapted to be adjusted relative to the pulley 48 in any desired manner.

The opposite ends of the cylinder or drum C are open and the inner surface or wall thereof is provided entirely thercaround with the longitudinally disposed a nmilar grooves or channels 50 which afford pdf-lu-ls or buckets to receive the grain separated from the straw, and as said cylinder or drum C rotates the grain within the grooves or channels 50 will be delivered upon the upper stretch of the endless conveyer 51. As is particularly disclosed in Fig. l il to he noted that the grooves or channels 50 are arranged one immediately adjacent the other so that the grain. will be substantially continuously delivered upon the convever 51 The conveyer 51 is operatively engaged with the shafts 52 and 53 which are supported l l Ti referred to.

naearao by the table 5t which extends entirely through the cylinder or drum G and is sup ported in applied position through the me dium of the cross beams included in the housing or superstructure'H. It is also to be noted that the table 54 is positioned above the axial center of the cylinder or drum 0.

The shaft 53 is positioned rearwardly of the cylinder or drum 0 while the shaft 52 is positioned in close proximity to an opening 56 formed in the table 54 adjacent the forward end thereof and at a point within the cylinder or drum G. The conveyer 51 travels through said opening 56 and causes the grain collected thereby to be discharged through said opening and upon the vibrating screen 57 extending entirely through the cylinder or drum G and arranged below the table 5r, as is believed to be clearly shown in the accompanying drawings,

As herein disclosed, the screen 57 is supported by the hangers 58 and the forward end of said screen 57 is operatively engaged through the medium of the pitman 59 with the cranks 60' of the shaft 39 hereinbefore It will therefore be understood that as the shaft 39 is rotated the requisite vibration will be imparted to the screen 57.

The screen 57 is of a width substantially equal to the width of the bore of the cylinder or drum 0 and as the cylinder or drum rotates, the straw as it iscarried upwardly by said cylinder or drum Cwill engage the screen 57 and be thrown downwardly, whereby a thorough separation of the grain is assured. The screen 57 also permits the passageof chaff and dirt therethrough so that when the grain is discharged from the screen 57 into the receptacle 61, the same will substantially be free of impurities.

Coaoting with the receptacle 61 is an elevator 62 including the endless carrier 63 which is driven from the shaft 64:. The shaft 64L has an extended portion provided with a pulley 65 around which passes the crossed belt 66. The belt 66 also passes around the pulley 67 secured to an extended portion of the shaft 53. The drum 67 has also disposed therearound the belt 68 which coacts with the pulley 6 hereinbefore referred to,

whereby it will be perceived that the con veyer 51 and carrier 63 will be caused to properly operate.

Positioned below the concave B is an apron 69 which serves to deflect any grain dropping between the bars of the concave B within the cylinder or drum C and adja cent the lower portion thereof, as is believed to be clearly shown in Fig. 2 of the accompanying drawings.

From the foregoing descrlptlon, 1t is t' opies of this patent may be obtained for five cents each, by addressing the Commissioner of Patenta,

hereinafter claimed.
