Lorena, in the countyof Beaver, Oklahoma,

huye inventedv aacertain new and useful Improvement ,in Cotton-Picking Fingers, of whichthe following is av full, clear, concise, andl exactdescription, reference being had to-zthe accompanying` drawings, forming a part of this specification.` l

My. inventionsrelates to cotton picking fingers, and hasfor its object the provision of an: improved finger that will .be more vsuited .to the rpicking of cotton than the fin.-

gers hitherto devised.

y' l wil-lexplain my inyention fully by reference tothev accompanying drawing, in which the preferred form of cotton picking finger is shown as constructed 'in accordance with my invention, the process of producing the finger and the construction of the finger being explained in connection with the drawing.

In the drawing- Figure l is a view in Yelevation ofa finger constructed in accordyance with my invention, the base portion of the finger being broken away for lack of room. Fig. 2 is a view in the direction of arrow 2 of Fig. et, illustrating one step in the process of constructing the finger. Fig.

, 3 is a View on line 3 3 ofl Fig. 2 illustrating the same process step shown by Fig. 2. Fig. at is a plan view illustrating the process step illustrated in Figs. 2 and 3. Fig 5 shows the structure of Fig. 4 after a groove has been formed to complete the toothed construction. Fig. (i is a cross-sectional view on line 6 6 of Fig. 5.

' Like parts a .e indicated by similar characters of reference throughout the different figures.

In he formation of the finger, a tapered bar, circular in cross-section, is selected, the larger end a of the bar constituting the base of the finger, the base portion being desirably of uniform diameter throughout, the balance of the finger tapering from the base portion toward the point c. The teeth are formed by means of a serrating tool d, whose striking end has two striking surfaces e e1 that arc desirably disposed at an angle approximating SO degrees. The ridge that intervenes between the striking sur aces e el constltutes 'the cutting edge of the serrating tool or chisel. This cutting edge is impressed upon l'- LJOHN-F.v APPLEBY, OF LORENA, OKLAHMA.

of about '45 degrees with respect to the axis of the rod, so that teeth are formed upon the rod that are obliquel-y disposed with-respect to the length ofthe finger. The cutting edge f ofthev tool isso rested upon the finger and the tool is so driven, that each cut'uponthe bar made by the tool constitutes a "chord of the circle defining thel shape vof the finger in cross-section. The force that' drives the tool into the'. metal of the rod is directed in a line that is lsubstantiallyinclude'd within a plane containing the aXis of the finger and vthe radius of the circle which bi-sects lthe chord above mentioned, in :which way the tool is caused to strike a square'blow upon the rod. Not only is the striking force given the direction indicated, but the tool is inclined-at an angle of about l() degrees from the vertical, so `that the advanced striking surface ewill raise the metal as indicated at g in Fig'Q, while the rear striking surface e1 will partially lay the metal just previously raised by the striking surface e. The tool is caused to descend into the rod a distance desirably sufficient to raise the metal by the action of the striking surface c enough so that when the. raised metal is partially depressed by the striking surface el, the teeth will proJect a slight distance beyond the perimeter of the rod as indicated most clearly in Fig. 6. The tool is moved along the rod longitudinally thereof and desirably in a straight line after it makes each indentation. As the ridges thus formed along the length of the bar present no barbs, I cut away a part of each ridge so as to form thereon a picking barb or point such as indicated at h in Fig 6. These ridges are desirably cut away by forming a groove i longitudinally of the rod, which groove not only removes enough of the ridges formed by the striking tool, to create the picking points l1., but is also desirably extended into the metal of the rod a sufficient extent so as well to expose tlzc points h to the cotton. The groove vz' is preferably of V-shape, as indicated most clearly in Fig. 6, so that no material that is gathered by the picking barbs may find permanent lodgment in the groove and so that no material that otherwise finds access to the groove may find permanent lodgment in the groove, the diverging Walls of the groove preventing material from securing an anchorage within the groove.

It will be seen that I have provided a procobliquely upon a metal rod,I causing the ser- -ratlng'tool to strike up metal from the rod previously raised each time the tool isimpinged upon the rod, causing the serrating tool whileinaking the next cut partially to restore the metal it has and forming a V-shaped groove through the teeth and a solid portion of the finger. As a result of this process, I am enabled to produce a cotton picking nger in the form of a tapered rod circular in cross-section, provided with teeth formed therein in a, row extending longitudinally thereof, and a V-sha )ed groove cut into the rod having one wall facino' the teeth, the

olpposite Wall of the groove being formed by t i e teeth, the points of the teeth projecting beyond the perimeter of the rod.

Having thus described my invention, I claim as new and desire to secure by Letters Patentz- A1. A cotton picking finger in the form of a rod provided with teeth formed therein in a row extending longitudinally thereof, and l a V-shaped roovecut into the rod having one wall facing the teeth, the opposite Wall of the groove bein formed bythe teeth, the points of the teet perimeter of the rod.
