2 Claims.
This invention relates to a cotton picker of the type shown in E. A. Johnston U. S. Patent 2,140,631 issued December 20, 1938, and more particularly to a novel arrangement and improved support of the mechanism contained in the picker housing.
A general object of the invention is to provide a housing head or support of such apparatus of a design which may be easily and economically fabricated preferably from sheet steel components, and to further provide a novel arrangek ment of the apparatus with connections to the support which add tothe strength thereof.
. A further object is to' devise a durable support of skeletal construction which combines :lightweight with an effective distribution of the material to achieve a rigid, strong and compact structure.
Another object is to support the main bearing assemblies of the picker drum mechanism on the internal bracing of the housing head.
A still further object is to provide a structural unit having a peripheral framework with an interlacing of braces therein consisting of straight interconnected beams arranged to clear various parts of the mechanism and at the same time afford an adequate support and mounting therefor.
A more specicobject is to devise an arrangement requiring few cross braces which are disposed in an effective relationship to withstand the loads imposed thereagainst.
The invention contemplates an arrangementv wherein the components of the casing head and the mechanism therein vare connected to each other in mutually cooperating relationship. Furthermore, the invention comprehends mounting each picker drum from a cam member which is arranged to form a connection between several members of the bracing structure.
These and other objects of the invention will become more apparent from the specification and the drawings, wherein:
Fig. 1 is a top plan view with parts broken away of a picker assembly with the cover plate removed, and
Fig. 2 is a fragmentary transverse Vertical sectional view taken substantiallyalong the line 2-2 of Fig. 1. y
Describing the invention in detail, the cotton picker comprises a housing or polygonal shell 2, the shape of which may best be seen in Figure l, and is formed of interconnected at generally vertical sections consisting of a front panel or paneling 4 and rearwardly diverging side panels or paneling 6 and 8 extending from opposite vertical edges of panel 4. Panel 6 has a rear section I0 which extendsfsubstantially perpendicular to forward panel 4 and merges at its rear edge with an adjacent `lateral edge of a -rear panel segment I2 extending generally parallel to front panel I0. Segment I2 is part of a rear panel or paneling structure generally indicated I4, which additionally comprises an outwardly angledpanel segment VI6 extending forwardly from the opposite lateral edge of vsegment I2 and merging with the rear edge of a more sharply outwardly angled panel I8 which connects at its forward edge with the rear edge of panel 8. The contour ofthe shell is determined by the mechanism contained therein and is designed to enclose' the mechanism with the least amount of material while maintaining flat sections. The forwardly offset rear side at the right of Figure l is designed to accommodate a wheel of an associated tractor upon which thepicker is mounted as shown in A. W. Scarratt, et al., U. S.

The other outer or rear end of strut 39 is connected as by welding at 36 to segment I6 of panel structure I4 adjacent thev forwardly directed corner construction at 38 formed by the juncture of segment I6 with panel I8 which provides a relatively rigid area. Strut 30 is substantially perpendicular to beam 28 which is approximately parallel to panel 4.
lStrut 32 extends generally parallel topanel 6 3 between panel 4 and the forward side of beam 28 and is connected at its rear end by welding as at 40 to the Vmain beam 28 in an area intermediate the middle of beam 28 and the end thereof connected to panel 6. The outer or forward end of strut 32 is connected as by welding to the panel 4 intermediate the ends thereof slightly .to the right of center as seen Fig. 1. 'The arrangement of strut 32 provides rigidity and resistance to the rearward thrust of the plants entering the front of therunit. The strut 32 is strengthened by an auxiliary brace or strut 42 extendin'gjbetween panel 6 and strut 32 generally parallel to beam 28. The outer end of .member Y42 isxconnected as by welding to panel 6 Vin an area interf mediate its connection with beam '-28 :and `said panel 4. 44 to strut 32 intermediate the ends thereof. The forward corner formed by the panels f4 'and 6 is strengthened by a secondary or an auxiliary strut or beam Y46 'extending .substantially perpendicular to strut 42.
