COTTON-PICKER.

ringfleld, in the county of Sangamon and tate dflhinoi's,

have invented a new and useful Ootton Picker, of which the followingis such. a full, clear, and exact description as enable others skilled in the art to make and use our said invention; A 1 r This invention relates, to cotton pickers purposeof the invention is to pull the fiber, by air suction, from the bolls of the-growing cotton plants'and deposit it in suitable re movable receptacles carried along with the -More specific'purposes of the invention are to provide afan ofimproved construction adapted to produce air-suction in the suction throughthe fan without clogging the fan; orting on the rear part of the bed of an or inary farm wagon, the fan and an engine for provide suction-tubes of im' ,roved construction; to provide simple an effective means for connecting the suction-tubes with the fan and to provide means for controlling the operation of the suction-tubes respectively. With these ends in view our invention consists in the novel features of construction and, combinations of arts shown in tlie annexe reference is hereby-Tmade and hereinafter particularly described and Referring to the drawings in which similar reference letters and characters designate like parts in the several views; Figure 1 is a perspective view of the complete apparatus in osition on a farm wagon; Figs.,2, 3, 4 and 5 illustrate, on an enlarged scale, details of the head. Fig.

The engine A, and e fan B, are fixed on a suitable platform 0 which extends across the rear part of the wagon bed X, and is secure bolts I) extending through the platform .and'through the bottom of the wagon bed A drum E is connected with the induction pipe I) of the fan B by a suitable coupling 6. The fan B is equip rotor comprising a disk 6 a ng l), and wings b all secured on the shaft b and connected together by bolts b secured on the ring 6 and prevents the fiber from. winding on and clogging the Wings 0 i the fan.

The flaring part of the ring K admits the cotton boll and renders the suction most effective in detaching the fiber'fro'm the boll-.- The delivery pipe M is connected with the outlet ipe b of the fan, t the free end of is a discharge-head N cona coupling m The shaped as shown in n, of greater v the outlet ipe M nected wit the pi e head N is prefera ly T Fig. 3, and has an outlet opening sectionalarea than the sectional pipe M; through charged, and a smaller orifice a "for the discharge of dirt extracted from the cotton as A segmental concavoslots '2) convex screen plate P ha de act the cotton arated by bars p serves to area of the i which the cotton is .dis

entering through the tube M and downward through the opening n; and the slots p in the plate permit the passage of dirt and its discharge tl'n'ough the orifice n. The

guides it discharge opening n being of enlarged area as described, the cotton becomes loosened as it passes downward along the plate P, andthe air pressure behind the cotton and propellmg it, expels leaves, stems, pebbles or other) dirt, through the slots p and the orifice? n.

i T1118 feature is of practical advantage because it admits of cleaning the cotton during its passage through the head, The cotton discharged. through the head is received in sacks O or other suitable receptacles which may be removed at pleasure.

In the drawmgs are shown a drum equipped with four suction-tubes; that being a con-= venient number to operate upon and pick the cotton from both sides of a central row and oneside of a row 'on each side of said central row; when the wheels of thelwagon are running bctweenrowsand the wagon is passing over the central row; it is obvious however,

that'a greater or less number of suction-tubes may be used, within the scope of the invention. a

The operation of the apparatus is as fol: lows :A team hitched to the wagon pulls the Wagon across the field with the wheels travel- Operators, one for each suctiontube, carry the free ends of the suction-tubes in their hands and walking behind the wagon apply the rings K to the bolls as they are reached in succession,

, as the wagon moves slowly along the rows;

and the suction in' the tubes induced by the fan, driven by the engine A, draws the fiber from the bolls, carries it through the fan B, and through the delivery pipe M and the discharge head and discharges it into the rece tacles 0. If it be desired to place one of tlic formcxtending crosswise of tubes in dis-use the pushed inward so that thegate will lie across and close the opening of the gate-pipe com' municating with the tube;

Having fully described our invention what we claim as new and desire to secure by Letters Patent is; i v y r 1. The combination of a wagon bed, a platthe wagon bed, bolts detachably connecting said platform with saidwagon bed, removable receptacles within the wagon bed, a fan mounted on said platform, an nected to operatesaid 'fan, a drum connected to communicate with the interior of said fan,

suction tubes ,connected to communicate with said drum, an outlet pipe connected to communicate'with the discharge opening of said fan; anda discharge head connected with said delivery pipe and adapted to discjhargeinto the removable receptacles in the wagon bed.

2. The combination of a segmental'con cavo-convex deflector provided with slots separated by bars; a discharge-head having a gate 9 of the gatepipe with which that tube is connected, will be engine on said platform condischarge opening for fiber and an orifice for 9
