GERARD 'BEEKMN, OF NEW YORK, N. Y.

` COTTON-HARVESTER.

SPECIFICATION forming pari. 0f Letters 'Patent N0. 495,007, dated. April 11, 1893. Application led November 15, 1890. Serial No. 371,525. (No model.)

`To yvr/ZZ whom it may concern.-

Bet kn own that I, GERARD BEEKMAN, actzen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvementsin Cotton-Harvesters, the said inhavingbeen described, also, in an application for United States Letters Patent filed by me on the 17th day of February, 1887, Serial No. 227,897, on which Letters Patent were granted to me on the 23d day of September, 1890, No. 436,770, by reference to which this will fully appear, the claims for the subject-matter described in the present application having been omitted by me from the said as required by the Patent Office, without any intention of abandonment.

The following is a specification of my invention, reference being had therein to the accompanying drawings.

My invention relates to that class of cottonharvesters in which the picking mechanism rotates backward at substantially the same rate of motion as that of the harvester over the ground.

The objects of my invention are to group and support several pickers in oneI elasticarru, such as is described in my said Letters Patent, and Iattain these objects bythe nicchanism illustrated in the accompanying drawings.

Figure 1 represents a plan view of the arrangement of adjoining arms, and pickers oi the kind shown. Fig. 2 represents a vertical section of a modified form of an elastic-arm, in which one elastic shaft sets in motion several pickers. Fig. 3 represents a perspective view of the same, the pickers being removed. Fig. 4 is an enlarged detail view showing the regulating wheel, R, in section; and Fig. 5, a horizontal section of Fig. 4 taken on the line w-a:.

Similar letters referto similar parts throughout the several views. e

Only a portion of the mechanism which I prefer-to employfor rotating shafts X is shown. It isthe same as that described in my said Letters Patent. Spools J are journaled in wheel F and rotated therein by means of abelt pressing against said spools, said belt being stationary or moving in a direction opposite to that of wheel F. To shanks Il, of spools J, are attwo or more pickers. The flexible shafts X are preferably composed of a tine coil of wire, substantially as shown in my said Letters Patent, but they may be composed of any other material, suitablev for flexible shafting. The pickers attached to the end of the flexible shaft X may be of any form of revolving picking device, suitable for seizing 'the ber of cotton, such, for instance, as those referred to in `my said Letters Patent. They may be vof string or of wire, or spiral spring, which wire may be rigid or exible,and may be covered with gotta-perche., rubber or textile fabrics, or with any other substance which will assist the cotton in wrapping itself around the pickers.

A short distance below the wheel F, is the regulating wheel R, having slots, U, through which pass the flexible arms N. Said flexible arms,N,are made of coilsof wire or of curved tubes. The slots U are elongated, as appear in Figs. 4 and 5, to permit the elastic movement of the arms N, due to the yielding action of the coils of wire O, at their upper parts, whereby they are attached to wheel F. At the lower extremities of the arms N, the pickersl forming extensions of the shafts X, are supportedin their divergent relation by means of the several elastic tubular ngers P. These tubular fingers P, are also composed of coiled wire or other suitable material adapted for flexibility.

In Figs. 2 and 3 is shown a modification of my invention, which modification enables a single flexible shaft, inclosed in an elastic arm, to rotate a number of' rollers. The roller, g, Fig. 2, in the form of a frustum of a cone,

is screwed upon the lower end of the shaft,Y X, and around this roller are grouped otherl conical rollers, h, h. Each of these rollers, g and h, has a picker, X', screwed into its outer and lower end. The bearings of these rollers are in the concaved plate, i, and con Vex-plate,

7e, Figs. -2 and 3, which are held together by theconical box, Z, the concave-plate, t', being screwed upon the lower end of the conical box, l. Below the plate, t', and surrounding each of the shanksof the rollers, g and h, are hollow nipples, m, m, upon which may be screwed the flexible-tip, P, P. The inward drag of the flexible-shaft, X, if made of aspitached flexible shafts X, giving rotation toV
