SAMUEL IV. BROWN, OF LOWELL, MASSACHUSETTS.

MACHINERY FOR CLEANING COTTON.

Specification of Letters Patent No. 13,564, dated September 18, 1855.

To all 107mm, t may concern Be it known that- I, SAMUEL IV. BROWN, of Lowell, in the county of Middlesex and State of Wassachusetts, have invented a new and useful lIachine for Picking Cotton; and I hereby declare that thefollowing specification, in connection with the accompanying drawings; constitutes a full, clear, and exact description of the construction and use of the same.

In referring to the drawings, Figure 1, denotes a plan or top view, Fig. 2, a right side elevation. Fig. 3, a left side elevation; Fig. 4, a longitudinal and vertical section at A, B, Fig. 1.

The nature of my said invention consists in more effectually picking and cleaning cotton by drawing and separating the fine dirt, dust, &c., from the cotton by exhausting the air and dirt from above the cotton as it is thrown forward above the secondary feed rolls. And in employing two or more sets of secondary feed rolls, to conduct the cotton to the second beater in several different places.

To enable persons skilled in the art to which my invention.appertains to construct and carry out the same, I will describe it as follows: I construct a frame of wood seen at A, A, to which I attach my improved iron grids, which can be seen at G and D. Above each of these grids I place the iron beaters seen at E, the beaters being firmly secured to substantial iron shafts seen at G, by means of the iron arms H, and rings G2. These shafts should be properly fitted so as to revolve in substantial metallic bearings.

At I can be seen the feed apron and at J, J, Fig. 1 the first set of feed rolls which are forced or pressed together by the lever K and spring Q2 attached to it, at O can be seen the stands to support the rolls J, there should be a bonnet formed as seen at L, and placed over the first beaters E for preventing the cotton from flying away where it is not intended.

Back of the bonnet L and over the second beaters F should be formed a dome or exhauster seen at M, in the interior of which a rack N is placed to prevent the cotton from being drawn 0E with the dirt there being a place left between the surface of the dome and the rack. At the top of the dome is formed a dust pipe seen at b which leads to the pipe e, in which the fan or blower P is placed to operate and which must revolve with velocity, for the purpose of drawing the dust and fine dirt from the cotton as it is driven along by the first beater E, into the dome M.

At R, R, R, R, can be seen several sets of secondary feed rolls supported by the arches h2, which revolve and conduct the cotton from the dome M to the second beater F in several different places so that this beater will strike and more thoroughly agitate the fibers of the cotton by reason of these secondary feed rolls conducting the cotton to the second beaters in several different places.

The driving pulleys on the beater shafts can be seen at ya, p, connected and driven by belt Z2. On one of the shafts is placed the balance wheel or crank H2. On the opposite end of this shaft G is fitted the gear e, which gears into and drives the gear s, to operate the various feed movements. On one end of the driving shaft G I place the pulley @2 which drives the fan P by means of the belt to2, the out end of this fan shaft being sustained by the stand y2. On the hub of the gear s is placed the bevel pinion u, these being both sustained by the stand y. The bevel pinion u gears into and communicates motion to the bevel gear t, on the hub of which is placed the bevel gear 7', they being properly sustained by the stand y. The bevel gear r gears`into and imparts motion to the bevel gear S2 and also by the hub of the gear t to the shaft O2 on which it is placed and fastened. This shaft O2 is properly sustained in the stands a2, a2, and imparts motion to the lower feed roll J by means of the bevel gears w. The lower feed roll J drives the upper one by means of the gears b2. The apron I is also driven from the lower feed roll J, by means of the gear 02 and Z2 the apron being revolved around the rolls 7b2 and g2.

The secondary feed rolls R, R, R, It, are driven by the bevel gears r, and s2, one of them being fastened to the shaft O2, and the gears f2 on both ends of these rolls to keep the movement of them connected if they should be pressed apart at either end by the cotton, these rolls being pressed together by the levers mi2, and springs n2, oper ating on the boxes in which these rolls revolve.

What I claim as my invention and desire to secure by Letters Patent is,

1. I claim my within described dome havthe cotton from the dome and deliver it to the second beaters, in several different places, so as to complet-ely separate and agitate the Cotton, to straighten and even the bers and force the dirt from it, essentially in the manner and for the purposes set forth,
