A-ground-engagin'g wheel 34 is carried on each of the axles 30 and supports the. rearward end of the structure 20. The structure 20 has on its rearward end 28, Figure 8, means for attachment of the structure to a pushing vehicle. Specifically, this means embodies a pair of laterally spaced upright bars 29positioned rearwardly of and spaced from the rearward end 28 of the structure 29 and each secured in spacedrelation to the rearward end 28 of the structure 2%. Each of the upright bars 29 carries a pair of attaching members '36 and 38 arranged in vertical spaced relation, the'att'aching members being secured to the forward end of a pushing vehicle 62, as clearly shown in Figure 8. When the attaching members 36 and 38 are attached to the pushing vehicle 62 the structure 20 is supported by the pushing vehicle for movement over a groundsurface. i

A plurality of upstanding housings 42 are positioned Within the structure 2% and extend in linear aligned spaced relation along each of the sides of the structure 20," the housings 42 extending along one of the structure sides being in spaced relation and staggered relation'with-respect to the housings 42 which extend dong the other of the structure sides with portions of the housing extending along one of the structure sides facing portions of the housing extending along the other of the structure sides. Each of the housings 42 embodies a drum 44' provided with a vertically extending slot 46 in the portion of 'thetdrum 44 corresponding to the facing portion of the housing. The housings 42 also include asleeve 43 circumposed about an rotatable about the drum 44 as an axis, the sleeve 48 having a plurality of vertically ex tending closed slots arranged in spaced relation therearound each registrable in turn with the slot 46 in the drum 44, the slots in the sleeve 48 being shown in Figures 2, 4, and 10 and designated by the reference numeral 50.

As shown in Figures 6 and 7, the sleeve 48 is-ni'ounted in a ring bearing member 52 for free rotation about the drum 44, there being provided a bearing member 54 interposed between the drum 44 and the sleeve '48 upward ly of the lower end of the latter.

An overhead conduit 56 having'one end open andlthe other end closed is positioned'so as to extend over the upper end of the support structure 20 with'the closed end contiguous to the forward end 26 and the open end adjacent the rearward end 28. The open end of the conduit 56 is connected by a flexible conduit to a source of suction, this being a draft fan 58 mounted upon a platform 60 carried by a pushing vehicle such as a tractor62 in Figure 8. I

A'collector housing 64 is carried on the platform 69 and an internal combustion engine 66 is mounted on the collector 64 and is operatively connected by means of a 'belt 68 to the draft fan 58. An exhaust conduit 7% conmeets the collector 64 with the fan 58. Other flexible conduits 72 connect each of the upper ends of the drums '44 with the conduits 56.

wise direction of the said one axle 30. Specifically, this means consists in a pulley 92 carried by the said one stub shaft 30, Figure 3, the pulley being connected by a belt 94 to another pulley 96 carried on a transversely arranged crankshaft 98 which is journaled in the upper end portion of the structure 20 adjacent the rearward end 28. The crankshaft 98 carries three cranks on each side of the conduit 56, as shown in Figures 1 and 3. The top of each of the drums 44 is provided with a socket 100 in which fits a pin 102 carried on the free end of each of a plurality of crank arms designated generally by the reference numeral 104. One crank arm extends to each of the cranks on the crankshaft 98, as shown in Figure 1. Upon rotation in the clockwise direction of the stub axle 30 which carries the pulley 92 each of the drums 44 or housings 42 is reciprocated between the lines a. as marked by arrows in Figure 5.

Means is also provided connecting the sleeves 48 of each of the linear aligned housings 42 to the adjacent stub axle 30 for rotational movement responsive to the rotational movement in clockwise direction of the adjacent axle. Specifically, this means embodies a pulley 74, Figure 3, mounted upon each of the stud axles 3i) and each connected by a belt 76 to a driven pulley 7 8 carried on one end of a longitudinally extending driven shaft 80 positioned on each side of the structure 20 and supported in bearings 81. Each driven shaft 80 carries three pulleys 82, one for each of the adjacent sleeves 48. The lower end portion of each sleeve 48 is provided with a grooved ring 86 constituting a pulley. A belt 84 drivingly connects each pulley 82 to the ring 86 on the adjacent sleeve 48 for effecting the rotational movement of the sleeves 48 responsive to the rotational movement in the clockwise direction of the adjacent stub axle 30. i A split collar 88, having a concave inner face, Figure 4, is circumposed about each sleeve 48 and encloses the portion of the belt 84 seated in the groove of the adjacent ring 86. Each collar 88 is mounted on a base member 90 supported on the structure 20 below each of the sleeves 48.

Guide means is provided projecting from the forward end of the supporting structure 20 for directing the cotton plants into the passageway provided between the housings 42. Specifically, this guide means comprises a pair of angularly shaped and diagonally spaced plates 106 and 108 carried by the forward end of the structure 20 and so arranged as to guide the cotton plants into the passageway provided between the respective housings 42.

Referring to Figures 12 to 19, inclusive, the reference butterfly valve to the throw 128. The second throw 1'34 numeral 110 designates generally a modified cotton picker supporting structure according to the present invention. In this form of the invention a plurality of housings 112 are arranged in linear aligned relation and extending along each side of the structure 110. An overhead conduit 114 is connected to each of the housings 112 intermediate the ends of the latter. One end of the conduit 114 is closed and the other end is adapted for connection to the fan 58 or other source of suction.

The structure 110 of Figures 12 to 19 inclusive has on its rearward end 111, Figures 12, 13, and 14, means for attachment of the structure to a pushing vehicle 109. This means includes a pair of laterally spaced upright bars 113 positioned rearwardly of and spaced from the rearward end 111 of the structure 110. Each of the upright bars 113 carries a pair of attaching members 115 and 117 arranged in vertical spaced relation, the attaching members being secured to the forward end of the pushing ve- In this form the structure 110 is supported by the pushing vehicle 109 for movement over a ground surface when the attaching members 1 15 and 117 are secured to the pushing vehicle 109.

Means is provided for connecting the housings 112, or the drums which constitute such housings 112, to the adjacent stub axles 118' for effecting projectile and contactile-movement of the housings 112 relative to the passageway which is formed between their facing portions.

Specifically, this means consists in a drive pulley 120 mounted on the inner end of each of the axles 118 and connected by a belt 122 to a driven pulley 124 mounted upon one end of a longitudinally extending crankshaft 126. The crankshaft 126 is journaled in the forward end and the rearward end of the supporting structure 110 and carries a pair of crank throws for each of the housings 112. As will readily be seen in Figure 12, there are two such crankshafts 126, one for each of the rows of housings 112. The first crank throw of each pair of crank shafts is designated by the numeral 128 and is shown, in Figures 12 and lito be connected to a butterfly valve 130 in the auxiliary conduit 116. A crank arm 132 connects such of each pair of crank shafts 126 (Figure 12) carries a coupling element 136 through which projects an intermediate portion of a normally horizontally disposed support bar 138, the intermediate portion of the bar 138 being operatively connected to the coupling element 136. One end of the support bar 138 is secured to the outer face of the adjacent housing 112, Figure 18, and the other end of the support bar 138 is slidable in an eye formation 140 provided on a horizontally disposed reciprocatory shaft 142. A crank element 144 on one end of the shaft 142 provides reciprocatory movement as shown in full lines and dotted lines in Figure 12 in response to rotation of a driven pulley 146 which is connected by a belt 148 to a drive pulley 150 mounted exteriorly of the adjacent wheel 152 and on the end portion of the stub axle 118.

A pair of angular and obliquely arranged plates 154 and 156 are connected to the forward end of the supporting structure 110 and serves as guide means for guiding the cotton plants into the passageway provided between the facing portions of the housings 112. As shown in Figure 17, the facing portion of the housing 112 is provided with a slot 156, closed at its ends, and connected by the auxiliary conduit 116 to the source of suction. In Figure 14 the dotted line showing indicates the tilting reciprocatory and contractile and extensile movements of the housing 112 responsive to rotation of the wheel 152 in the clockwise direction as viewed in Figure 13.

In use, the cotton picker of the present invention, in either of the two embodiments heretofore described, is attached to a pushing vehicle such as a tractor 62 with the forward end of the structure of the picker supported by an attachment member connected to the upper end of the structure and to the tractor. This enables the structure to be driven over a row of cotton plants with the plants passing between the guide means and lifted into the passageway provided between the respective housings which extend along each sideof the structure. When the cotton picker shown in Figures 1 to 7, inclusive, is employed, the rotation of the sleeve 48 on each of the housings 42 "brings the slots 50 in turn into registry with the slot 46 and the drum 44. The opening and closing of the slot 46 and the drum 44 by the rotation of the sleeve 48 applies a sudden suction to the cotton bolls on the plants passing between the housings 42, effectively extracting the cotton from the bolls and carrying the cotton through the conduits 72, 70, to the collector 64. Most of the dirt, leaves, and trash are permitted to fall to the lower end of the drum 44 for later removal while the cotton is carried upwardly through the conduit 56 by means ofthe suction fan 58 When the cotton picker shown in Figures 12 to 19 is employed, the reciprocatory movements of the housings 112, and the extensile and retractile movements of the housings 112, together with the opening and closing of the butterfly valve in each of the auxiliary conduits 116 serves to remove the cotton from the cotton plants and to carry the same upwardly through the conduits 116 and 114 to the draft source and to the appropriate collector. The opening and closing of the butterfly valve 130 in each of the conduits 116 applies a sudden suction action to the cotton bolls on the plants passing between the housings and effects the extraction of the cotton from the bolls in an efiicient manner.
