3 Claims. (Cl. V56-33) This invention relates to new and useful improvements in cotton harvesters and the primary object of the present invention is to provide novel and improved means for effectively combing cotton and for removing the weeds from the cotton during the combing operation.

Another important object of the present invention is to provide a cotton stripping and combing machine involving oppositely rotating power driven stripper rollers each of which supports a plurality of radially slidable combing fingers that ride against a stationary cam member positioned in each roller so as to project certain of the fingers outwardly from their supporting roller and toward each other during rotation of the roller for the purpose of eectively combing and stripping cotton.

A further object of the present invention is to provide a cotton combing and stripping machine consisting of a lower pair of stripper rollers which are located below the combing rollers and which rotate in relatively opposite directions and oppositely to the combing rollers for the purpose of pulling weeds, twigs or the like from cotton being handled by the combing rollers.

A further object of the present invention is to provide a cotton combing machine of the aforementioned character involving a pair of conical rollers which may replace the combing rollers and a drive connection between the combing and stripping rollers so that the combing rollers replaced by the stripping rollers and a lower set of stripping rollers Will rotate in a similar direction to convert the device from a cotton combing machine to a corn puller, in a convenient manner.

A still further aim of the Vpresent invention is to provide a cotton stripping and combing machine that is extremely simple and practical in construction, strong and reliable in use, eicient and durable in operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, :reference being had tothe yaccompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a top plan View of the present invention operatively mounted on a tractor and coupled to a collecting wagon; l

Figure 2 is a longitudinal vertical sectional View taken substantially on the plane of broken section line 2 2 of Figure l;

Figure 3 is an enlarged fragmentary longitudinal vertical sectional 'view taken substantially on the plane of section line 3 3 of Figure l;

Figure 4 is an enlarged fragmentary transverse sectional view taken substantially on the plane of section line 4 4 of Figure l-with the rods omitted;

`Figure 5 is an enlarged fragmentary transverse sectional View taken substantially on the plane of section line 5 5 of Figure l;

Figure 6 is an enlarged detail sectional View taken substantially on the plane of section line 6 6 of Figure 3;

Figure 7 is a fragmentary longitudinal sectional view of one of the combing rollers taken substantially on theplane of section line 7 7 of Figure 6 with one row of combing lingers removed for the purpose of illustration;

Figure 8 is a view similar to Figure 5 but showing the invention in slightly modified form; and

Figure 9 is a fragmentary top plan view showing'the two sets of rollers employed in conjunction with the modified form of the invention disclosed in Figure 8.

Referring now to the drawings in detail, wherein for ICC the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral 10 represents a slide housing having its rear end suitably secured to a wheeled support 12 which is coupled to a collector, such as a wagon 14, by a tow bar 16. The forward open end vof the housing 10 iixedly supports ground shoes or skids 18 that will ride upon the ground as the housing is moved forwardly by a tractor 20 to which the support 12 and housing 10 are connected by a rigid framework 22.

The

inner side walls

24 and 26 of the housing 10 fixedly support horizontal arms 2S and 30 having holding bearings 32 and 34 secured thereto. The supportingrshafts 36 and 38 of a pair of side-by-side, hollow cylindrical, combing rollers 46 and 42 are held inthe bearings 32 and 34 by set screws or the like 44 and 46 so that the

rollers

40 and 42 may rotatefon shafts 36 and 38.

Fach of the rollers 40 `and 42 is provided with circumferentially spaced, longitudinally extending rows of apertures 48 and bushings 49 are secured to lthe .rollers lin association with each of the apertures 4S such that the bores of the bushings are in radial alignment therewithfor slidably receiving the rows Vof combing lingers or short rods 5l). The inner ends of the fingers 50 lare enlarged to form seats 51 for the inner'ends of coil springs 52 that embrace the lingers 50. The springs -52 are biased between the inner peripheries of the

rollers

40 and 42 and the Vseat-.forming ends 5l to yieldngly urge the fingers 50 radially inwardly of the outer peripheries of their supporting rollers.

The intermediate portions of Ythe shafts 36 and 38 are formed with bar-cams orelongated.cammembers-Sl'that extend longitudinally of the rollers and within the rollers'. The lobes 56 of the cam members 54 aredisposed ina common plane and extend toward each other from Vthe axes .of the shafts 36 and .38, so that as the lcylindrical rollers -4ll and 42 rotate, the seat-forming ends '51 of the rows of fingers Vof the rollers closest together will ride against the .lobes `56 to project these yfingers radially outwardly from the rollersfas shown inFigures l and 7.

in order Vthat the fingers yprojected from one roller will not engage the fingers projected from the other roller, `the rows of finger-accommodating apertures 48 in one roller are lstaggered relative to the yrows of .apertures in 'the other roller, or else, ythe rollers are longitudinally offset from each other, and through thisconstruction, lthe projected fingers of one roller will be interdigitated withthe projected fingers ofthe other roller.

Means is provided for rotatingthe'rollers'40 and `42^in relatively opposite directions so that roller V40 "will rotate clockwise and roller 42 willrotate counter-clockwise when viewing these rollersfrom the rear ends thereof,vas shown in Figure 5. This roller rotating means -consists of -a longitudinal driven shaft 58 `rotatably supportedby support 12 and having a drive connection 60 with the powerV take-off shaft 62 of the .tractor 20. A suitable reversingA gear-mechanism 64 is coupled to the sections of shaftrSSl and actuated by a hand lever 66 -so that Vshaft .58 may rotate either clockwise .or Aanti-clockwise for a Vpurpose presently to be described. v

The vforward end of shaft 5S fixedly supports a sprocket 68 that is connected to a sprocket 70 fixed to the rear end of roller 40 by an endless sprocket .chain 72. The upper flight of chain 72 engages the bottom portion of a sprocket 74 fixed to the rear end of roller 42.

A lower pair of side-.by-sidelcylindrical `

stripping rollers

76 and 78 underlie the

combingrollers

40 and 42, and are disposed closer together than are the combing rollers.

The rollers 76 and 7S have supporting shafts 80 and 82 which are held in bearings 84and 86 carried by arms-88 and 90. The arms S8 and 90 'are iXedto the sidewall-s 62 and 58. Shaft 92 xedly supports a second sprocket 100 that is connected to a sprocket 102 fixed to the rear end of roller 78 by an endless sprocket chain 104 to cause roller 78 to rotate ina similar direction as

shafts

58 and 92.

An idler sprocket 106, suitably carried by housing 10, engages a sprocket chain 108 that extends about a second sprocket 110 fixed to the rear end of roller 78 and the upper ight of chain 108 engages the bottom portion of 'a sprocket 112 fixed to the rear end of roller 76, so that

rollers

76 and 78 will be driven, as shown by arrows in Figure 5, to pull weeds, sticks or the like downwardly from cotton engaged between

rollers

40 and 42.

Longitudinal conveyor belts 114 and 116 are carried by

rollers

118 and 120 mounted on the

side walls

24 and 26 of the housing 10. Belt 114 is disposed between roller 40 and side wall 24 and belt 116 is disposed between roller 42 and side wall 26, as shown in Figure 4, so that cotton leaving the

rollers

40 and 42 will pass onto the belts 114 and 116. The

rollers

118, 120 at one end of each of the belts 114 and 116 are power driven by suitable means, such as by power take-off shafts 62, so that the upper fiights of these belts will move rearwardly to conduct cotton to the rear of the housing where the cotton will drop onto a transverse conveyor 122 suitably mounted upon the support 12.

Conveyor 122 comprises a pair of rollers 124 with central peripheral V-shaped grooves 126 over which there is engaged an endless conveyor belt 128 that will form a transverse trough. One of the rollers 124 is power driven by suitable means operatively connected to the power take-off shaft of the tractor to move the belt 128 toward the inlet 130 of a blower unit 132 that is supported on support 12. The outlet 134 of unit 132extends to the wagon 14 to direct cotton leaving conveyor 122 and entering the inlet 130, into the wagon 14.

Figures 8 and 9 illustrate the present invention in modified form whereby the device may be employed for pulling corn. In this embodiment, the

rollers

40 and 42 are replaced by conical sprally

ribbed rollers

40a and 42a whose rear ends carry

sprockets

70a and 74a that engage the sprocket chain 72a in the same manner described in coniunction with Figure 5, however, lever 66 is actuated to drive shaft 58 oppositely from the direction of drive utilized with the

rollers

40 and 42, previously described, artig hence,

rollers

40a and 42a will rotate Atoward each o er.

Thesprocket 100:1 on shaft 92a engages an endless sprocket chain 10411 that extends about the sprocket 112g at the rear end of roller 76a and the lower ight of chain 104aengages over the sprocket 110a at the rear end of roller 78a so that rollers 76a and 78a now rotate downwardly toward each other as do the

rollers

40a and 42a.

In practical use of the present invention, the tractor is moved forwardly and cotton plants are engaged between the

rollers

40 and 42 so that as the rollers 40 and 42y are driven, the projected fingers 50, which extend between the

rollers

40 and 42, will strip the cotton from the plants and effect a combing of the cotton. The cotton will be lifted by these

rollers

40 and 42 and dropped onto the belts 114 and 116 where the cotton is moved rearwardly onto the conveyor 122. The cotton is drawn from the conveyor 122 by the unit 132 and directed into the wagon 14. During the combing of the cotton by the

rollers

40 and 42. they

rollers

76 and 78 will pull weeds, twigs and the like downwardly, and drop this foreign matter onto the ground.

Tn order to employ the device as a corn puller. the

rollers

40 and 42 are replaced by the

rollers

40a and 42a and the rollers 76a and 78a are driven in the manner described in cnniunction with Figure 8. What is claimed as new is as follows:
