1 Claim. 1

My invention relates to cotton picking machines of the kind disclosed in United States Patents Re. No. 19,411 issued January 1, 1935, No. 1,894,198 issued January 10, 1933, No. 2,058,513 issued October 27, 1936, No. 2,023,491 issued December 10, 1935, No. 2,058,514 issued October 27, 1936, No. 2,085,046 issued June 29, 1937, and No. 2,162,750 issued June 20, 1939.

My invention has for its object to provide a secondary dofiing and moistening device with spokeless rubber rimmed rings so as to avoid the possibility of the cotton clogging around a hub and spokes such as those shown, for example, in Pat. No. 2,023,491, Fig. 15, and to provide a simple, inexpensive and effective metering device for regulating the supply of water to the spindles by gravity feed.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention also resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointed out in the appended claim, reference being had to the accompanying drawings, in which:

Fig. 1 is a top plan view of a portion of a cotton picking machine embodying my invention, parts being broken away.

Fig. 2 is an enlarged detail plan view of a portion of the spindle moistening and dofiing device.

Fig. 3 is a vertical section on the line 3-3 of Fig. 2.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all the figures, the main frame of the machine is composed of angle irons i, l l 2 indicates the drive shaft, 3 the driven shaft, 4 the conveyor chains, and 5 the spindle carrying slats which are connected at 5 to the chains.

Referring now to Figs. 1, 2 and 3, it will be seen that the spindle moistening devices comprise a set of superimposed rubber rings 6 carried on annular metal stiffeners 1. These stifieners difier from those shown in Pat. No. 2,085,046 principally in that they are without hubs and spokes. The rings 6, l are supported in place by flanged rollers l carried on shafts 8, the flanges 9 of which project between adjacent rings 6, I at two places, and by the spindles I2, hinge elements l3 and passing slats at a third place. The shafts 8 are journalled in suitable bearings II on the frame of the machine.

The moving slat conveyor draws the spindles between the rings 6, serving to impart rotation to the rings, during which water is applied to the rings 6. The moistening of the rings is accomplished by means of sponges l4 projecting through openings in a tubular support into which metered quantities of water are delivered by a pipe 20 from a suitable source (not shown). Beneath a valve 20, that communicates with the source of water supply, is a pan I! carried on a plate [8 and having a pin I!) to project into the valve 20 to open it when the pan is lifted. The pan delivers water into the top of the sponge tube iii to moisten the sponges I4. The long arm 2! of a lever which is pivotally mounted at 22, is secured to the plate l8 and has a short arm 23 to be engaged by an operating bar 24. The bar 24 is pivoted at 25 to a suitably mounted bracket (not shown) and extends over the moistener. An adjustable stop 26 is provided to limit the rise of the pan I1, and thus control the degree to which the valve may be opened by the lever 2|, 23 when it is rocked by the bar 24, the bar 24 being operated by a lug (or lugs) 21 secured to one or more of the chain hinges l3 (see Fig. 1).

This application is a division of my application filed March 29, 1944, Ser. No. 528,868, patented April 27, 1948, Pat. No. 2,440,450.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the construction, operation and advantages of the invention will be clear to those skilled in the art.

What I claim is:

In a cotton picking machine wherein is provided an endless conveyor with cotton picking spindles and a spindle moistening means: the invention which comprises an improved spindle moistening and auxiliary doffer device that includes a set of spaced apart spokeless rings between which and contacting the edges of which the spindles are drawn, means for supporting said rings for rotation about a common axis, said supporting means comprising in part said spindles and in part two ring contacting rollers spaced apart at the outer periphery of said rings as a set and having ring-supporting flanges disposed between each pair of rings, and a ring-moistening means disposed at the outer periphery of said rings as a set and located between and spaced from said rollers, said ring-moistening means including a tubular support, having openings, sponges in said openings and engaging said rings at their adjacent edges, and means to admit metered quantities of water into said tubular support to moisten said sponges.
