UNITED STATES PATENT 'OFFICE WILLIAM C. JILLSON AND AMOS B. PALMER, UF WILLIMANTIC, CONN.

IMPROVEMENT IN MACHINES FOR OPENING COTTON, &c.

Specilication forming part of Letters Patent No. 110,368, dated December 20, 1870; reissue No. 4,312, dated i March 28, 1871; reissueNo. 7,526, idated February 20, i877 g application tiled February 8, 1577.

To all ywhom 'it may concern Be it known that we, WILLIAM O.J1LLsoN and AMOS B. PALMER, both of Willimantic, county of Windham, State ofConnecticut, have invented certain new and useful Improvements in Machines for Opening Fibrous Material, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, making a part of this specification, in which- Figure 1 is a longitudinal sectional view of the machine, and Fig. 2 an upper plan view with the covering hoods or bonnets removed.

Similar letters of reference denote correponding parts wherever used.

The object of the invention is to open or loosen up and clean the fibrous material operated upon without injury to the staple, thereby putting it in condition to be more easily worked by the subsequent machinery employed in the various manufactures thereof; Aand to this end the invention consists in the employment, in a machine for opening up' and cleaning fibrous material, of a series of revolving pivoted or yielding whipper-rods or beaters, arranged within an inclosing shell or case, for confining the material while being acted upon by said whipper-rods or beaters. These pivoted or yielding rods or beaters are attached by their ends to a rotating drum or reel, and, by preference, are so arranged that those of one row or series on the drum shall alternate with, or be set opposite, the spaces between those ofthe preceding series.

A B are sections ot' the skeleton drums. a a are the cross-bars connecting the drumheads, and upon which the whippers are hung, and b b are the whippers, bent at one end to form an eye, which eye is slipped over the cross-bars before the drum is put together. The dotted lines show the position the whippers assume when in motion. C G are coils of wire or washers, also slipped over the crossbars, and which serve to regulate the distance at which the whippers are to be set from each other, and also to arrange those of one row or series opposite to the spaces oi'those in the preceding row or series, or, in other words, in such manner as to breakjoints therewith, for preventing any portion of the iibrous material from escaping without being acted upon by some of the beaters. F is a slot or opening, through which the iibrousmaterial to be operated on may pass, and this may or may not be furnished with feed-rolls, as desired. G G are the central shafts of the skeleton drums, and are journaled properly in the side of the machine frame creasing. E E are openy screens beneath the drums. H H are the bonnets or hoods which form the upper portion `of the cylinder inclosing the whippers.

The operation of this machine will be readily understood. The tibrous material is passed' in at F, and the whppers loosen or lighten it up, and in turn lpass it out at D; or, if desired, it can be passed out between two rollers, and over an apron. Each one of these arms being independently attached, if either of them is clogged or lilled up it does not affect the workin g of the others. Thus the ber cannot possibly be torn or injured.

We are aware that revolving shafts with radial projecting arms are old in cotton-openers; but their operation was very imperfect for two reasons: rst, because, from their being rigid and unyielding, they injured the staple by breaking it, and thus shortening it to such an extent as to largely diminish its value; and, secondly, on account of theirrigidity,"`they sometimes, when they came in contact with stelles or bits of iron, which are frequently found in raw cotton, set the machine on fire. These two defects, which so seriously impaired the usefulness of this class of machines, are entirely obviated by adapting the whippers to readly yield when they meet with an obstruction; and the strength of the blow which is struck by the arms is thus regulated by the weight and velocity of the whipper. We are also aware that a long thin piece of metal has been loosely hung on a drum for opening cotton; but this is objectionable for the reason that clogging ofthe fibrous material at any one point on the bar a'ects the entire bar, and thus the staple is torn and injured; but we are not aware of any such machine in which yielding or pivoted whipping rods or arms are used.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a machine for opening fibrous materi- 2 mss al, the combination, withan inclosing shell or case, of a series of yielding whipper rods or arms, arranged and rotating within said shell or ease, substantially as and for the purposeLa described.

2. In a ina-chine for opening fibrous material, the combination of revolving pivoted whipper rods or arms and an inclosing shell or case for confining the fibrous material while being acted upon by they whippers, all substantially as described.

3. In a machine for opening flbrols material, two or more reels or pulleys, provided with hinged or pivoted whipping-rods, in combination with two or more shells or concaves, these parts being constructed and arranged substantially as shown and described, whereby the material, after being partially opened by the first set of whippers, shall be fed to the second set of whippersby the action of the first,

substantially as set forth.

4. In. combination with the whipper-rods and reel-bars, constructed as shown, the elastic sleeves for separating the whipper-rods,

and allowing them to yield laterally, substan-
