(Cl. I56-42) 7 Claims.

'M5/:invention relates to cottonpicking machines of the kind disclosed in yUnited States Patents No. Re. 19,411 issued January l, 1935, No. 1,894,198 issued January l0, 1933, No. 2,058,513 issuedOctober 27, 1936, No. 2,023,491 issued December 10, 1935, No. 2,058,514 issued October 27, 1936, No. 2,085,0461issued June 29, l1937, and No. 2,162,750 issued June 2i), 1939.

My present .invention seeks to provide an improved means for rougheningrthe steel wire spindles of the cotton picking machine.

Other 4objects will in part be obvious and in part be pointed out hereinafter,

To the attainmentiof the aforesaid objects and ends, the invention also resides in the novel details of construction, combination and arrange-- ment of parts, all of which will be first -fuily described in the following detailed description, and then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Fig. 1 is a top plan view of a portion fof a cotton picking machine embodying my invention, parts being broken away and parts beingshown in-section Fig. 2 is an enlarged detail section on the line 2 2 of Fig. 1.

Fig. 3 is an enlarged detail horizontal section on the line `3 3 of the tubular post in Fig. '2 and a pair of springy rods carried thereby.

Fig. 4 `is a detail perspective on an enlarged scale View of oneof the shoes.

vReferring now to .the accompanying drawings, in which like numerals and letters of reference indicate like parts in all ythe figures, the `main frame of the machine includes angle irons i, la, I b, cross bars Ic, Id and longitudinal bar le, 2 the drive shaft, 3 the driven shaft, 4 the conveyor chains, 5 the spindle carrying slats and 5a the brackets which connect the slats to the chains. The main .frame is of known construction and per se is not a part of my present invention.

The spindle roughener is best `illustrated in Figs. 2, 3 and 4. A shaft' carries a set of spaced rigid discs 1 to the under faces of which are secured abrasive rings 8. Thediscs 1 are spaced apart by suitable spacers 9 and secured by arnut I'Il threaded on the shaft so that the shaft and the discs With their abrasive rings comprise a unitary structure. The shaft lis bored at its lower end to set on a pin I! carried by a bracket I2. The upper end of the shaft carries a swivel head I3 having trunnions I4 to rest in the bifurcated end of an arm I5 pivotally mounted at I6. An adjustable stop I1 limits the distance the 2 arm may rise, and hence limits the Ilift of ythe stack of abrasive unit. This unit is-res-ili'ently suspended by .means Yor a .lever .'18 fulcrumed at I19and held by a spring pressed'bolt 2120. 'Thellever i8 has its freefend inserted in an eye for IloopfLI on Vthe -arm I5.

22 is a pipe, carried by fthe fir-fame 4of the machine. On the pipe 212 -is .pivoted va rocker 23:one end of ,which-presses on .the swivel head I3 vWhile the other end is pivoted toan. eyeboltfzkthreaded into the upper end of a tubular'post 125 on 'fthe lower end of which post is a foot 21 whichmay ride up and down in a xed guide :(26. Thefpost 25 carries suitably spaced ,pairs of rods 1:28 having ends 29 on Which'are carried shoes .lf3-0 lthat project between the adjacent abrasivedisc' units'. When in non-operating position the shoes rest on top of the .metal disc elements 1 leaving both the shoes 30 and the .abrasive element/8 outoi contact with the spindles 32. 'The shoes ..30 have tapered front ends 3l :to cause the :spindles to ride up over the arms .3.0 at Val1 times. At the ends adjacent the .post 25 guards 33 are secured on the shoes 30 to prevent cotton from :being thrown over those lends and accumulatingvonathe arms 28.

An operating arm `34 is secured to-the'pipefzz, to which the rocker 23 is also secured for the purpose of rocking the rocker 23 and thereby lowering the abrasive units shaft 6 and raising the post 25 in consequence of which fthe vspindles 32 will be held in contact with the abrasive; The arm 34 is operated by a piston 35 in a cylinder36, the piston rod 31 being pivoted to the arm 34. Suitable operating iiuid is admitted into the cylinder 36 from a suitable operator-comtrolled source (not shown-but wel1=known^l via a pipe 38.

`The shaft '6 is `rotated-step-by-step at suitable intervals by means of a vpawl-carrying-lever135 pivoted on shaft 6 and having a pawl-40 lto engage a ratchet 4I on the upper 'face of the top disc 1. The lever 39 has a pin-42 which lies'in an elongated slot 43EL in a connecting rod L43 Athat is pivoted to the yoperating lever 44 (see Fig. '1). The lever 44 is supported in any suitable wel] known way, on a pivot 44a.

A rock shaft 45, mounted on the frame of the machine in any suitable known manner,` carries' ngers 4B that project between the elements gof the abradingunit to throw out any cotton 'that vided an endless conveyor with cotton pickingl spindle-carrying slats: the improvement which includes a spindle roughening device between the elements of which the spindles are drawn by thev endless conveyor; said device comprising a vershaft; means for mounting said shaft for longiltudinal movement; a post, shoes carried by said post; means for mounting said post for longitudinal movement parallel to that of said shaft; op

tical set of abrasive-carrying discs spaced apart on a shaft, a corresponding set of spindle engaging shoes on a post, the shoes projecting in between pairs of said discs and spaced therefrom, the spindles being carried by the conveyor between the abrasive-carrying discs and the shoes, and means for moving said abrasive-carrying discs and said shoes in opposite directions along the axis of said shaft to bring the abrasive surfaces and said shoes into operative engagement with said spindles, said last named means comprising yieldable means for suspending said abrasive-disc-carrying shaft, means for suspending said shoe-,carrying post, a rock shaft with a rocker engaging said abrasive-disc-carrying shaft and connected to said post by virtue of which as said rocker is moved to depress the abrasive-disc-carrying shaft it willsimultaneously lift said post for purposes described.
