MACHINE FOR OPENING AND CLEANING COTTON.
SPECIFICATION forming part of Letters Patent No. 485,272, dated November 1, 1892.
Application filed February 29, 1892- Serial No. 423,185. (No model.)
.To all whom it may concern.-
Be it known that I, WALLACE P. GROOM, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Machines for Opening and Cleaning Cotton, of which the following is a description sufficient to enable others skilled in the art to which the invention appertains to make and use the same.
My invention relates to apparatus the chief purpose of which is to open or loosen up and clean cotton fiber preparatory to carding and other processes to which cotton is subjected in the ordinary course of manufacture. The operation of opening or loosening up of matted cotton fibers at the cotton-spinning mills is for the double purpose of separating from cotton sand, dust, and other extraneous matter comrningled with it and to bring it into condition for further manipulation.
In consequence of the severe compression to which cotton is subjected for purpose of shipment the fiber, together with the extraneous matter with which it is commingled, becomes more or less firmly matted. In order to loosen or open up cotton for purposes of manufacture,resort was formerly had to a process of whipping with willow whips, called willowing, and latterly to much harsher treatment in machines called willows or boaters, in which the whipping or heating is done by rapidlyrotating metal boaters, which pound or thrash the fiber as it protrudes from between feed mechanism. The mechanical devices heretofore employed, however, fail to fully accomplish the result desired. Not only is the loosening up of the cotton incomplete and the elimination of the extraneous substances imperfect, but the treatment of the staple is so harsh and severe as to greatly injure it, the same being lacerated and broken by the fierce blows of the rapidly-revolving metallic heaters.
Itis the purpose of my invention to attain a much more nearly-perfect elimination from the lint-cotton of all extraneous substancessuch as cottonseed, (whether whole, broken, or immature,) sand, dust, leaf, motes, &c. without injury to the staple. My method of opening or loosening up the fiber 1s aprocess which may, perhaps, be appropriately designated as re-ginning. By this process the lint-cotton is freed from the larger part of the extraneous matter with which it is commingled, as aforementioned, the same having passed through the gin with the cotton in a former process called ginning. It is also loosened up much more thoroughly, notwithstanding the treatment itreceives, which treatment is comparatively gentle, though finally positive.
The main feature of myinvention consists, essentially, in a rotating whipper or opener in which the parts coming in actual contact with the fiber are flexible or elastic or in which flexible or elastic openers are used in conjunction with rigid openers, the result being in either case that the matted cotton is subdued and loosened up without injury to the fiber.
An important feature of my invention in this connection consists in making the openers of different lengths or degrees of radial projection and in arranging them in such relation to each other that the fiber as presented by feed mechanism is treated successively to different degrees of force, strain, orpull in such manner that the cotton is first acted upon by comparatively long elastic resilient brushes or openers, which project the full width of the space between the feed mechanism and the periphery of the rotating whippers, and then to others less elastic and of less degree of radial projection. The result of this is that where the cotton is matted the fibers are gradually loosened and separated without breaking, straining, or otherwise injuring them,sinceif thefirstbrush-openersencounter a matted portion of cotton they yield before it, while loosening the fiber slightly, and the succeeding more rigid openers eifectually subdue and open up the matted cotton with-.
out lacerating or breaking the fiber.
An incidental feature of my invention consists in the combination, with a rotating whipper, substantially such as herein designated, of a series of levers similar to those used in what is known as the piano-feed arrangement, formed with auxiliary yielding sections or extensions, which, while presenting any overhanging cotton to the rotating whipper, readily adapt themselvesto any excess of passing material.
Finally, my invention consists in the special construction and arrangement of parts herein shown and described, by which my invention maybe rendered available in practice.
In the accompanying drawings I illustrate means for practically carrying out myrimprovements, although I do not confine myself to the identical form and construction of parts shown, since it is obvious that various modifications may be made in arrangement and detail without departing from the essential features of my invention.
Figure 1 is a diagrammatic representation of the several parts of apparatus which may be employed in connection with my improved opening mechanism. Fig. 2 is an enlarged diagram of the feed-roller and a lever with the adjoining portion of the whipper, illustrating the treatment to which the cotton fibers are subjected. Fig. 3 represents projections of whippers or'ope'ners shownin Fig. 2; Fig. 4, a longitudinal section of a portion of the periphery of the whipper cylinder shown in Fig. 2, illustrating the arrangement of the openers in different lateral planes with relation to each other. Fig. 5 is an elevation of the inner end of one of the feed-levers; Fig. 6, a face view of the same; Fig.7, a rear view of one of the auxiliary extensionpieces detached from its lever; Fig.8, a front View of the end of a feed-lever without its auxiliary extension-piece. Fig. 9 is a transverse section of a preferred form of whipper; and Fig. 10 an elevation of the same, the central portion being broken away. Fig.11 is an elevation, and Fig. 12 an edge view,of one of the segments of which the whipper shown in Figs. 9' and 10 is built up.
An endless apron or latticecreeper A conveys the cotton loosely spread thereon to afeed-roller a and to a series of levers B,siinilar to those heretofore employed in cottonopening apparatus of this class. The levers B are of ordinary construction and arrangement, excepting that each is formed at its inner end with a pivotally-connected extension-piece b. This extension-piece 1) consists of a finger b, the upper surface b of which when the extension-piece b is in its normal position forms an additional feed-surface to hold up overhanging cotton, for which heretofore no provision has been made. These devices 1) are held in their normal positions by counter-weights b or equivalent means, which will permit the fingers b to yield and adapt themselves to an excess of pressure upon their upper surfaces 19 The frame or cylinder of the rotating whipper 0 may be constructed or built up in various ways, the essential feature in this respect consisting in providing suitable supports for the various openers used. Taken as a whole the whipper O is practically a cylinder having a series of radial openers of prescribed forms. These series of openers are also preferably of difierent degress of radial projection, as illustrated more clearly in Fig. 2. The distinguishing feature of my invention in this connection consists in the use of flexible material in the formation of these radial openers, either alone or in conjunction with openers formed of rigid material. Thus in Fig. 2 the longer openers c are not only flexible, but are also elastic and resilient, being formed of bristles, elastic wire, or equivalent material. These are preferably arranged in the form of and largely perform the function of brushes, combing oropening out the lighter and less matted fibers, while yielding and bending when closely or firmly matted portions of the cotton are encountered without cutting, tearing, or damaging the fibers. Next in order inFig. 2 is a series of openers 0 formed of leather or other slightly-flexible material. These openers e do not project out quite so far radially as the brushes c,the
difference of projection, however, being coinparatively slight in practice, amounting in some cases to not more than one-eighth of an inch. The shorterlength of the openers c is designed to prevent their striking too harshly against matted portions of the cotton as yet unopened by the brush-beater c, the object being to subdue and loosen such matted portions by a comparatively stiff but yielding blow, which will not endanger the integrity of the individual fibers, while loosening them and opening them for the action of the brushbeaters 0.
Should the matted portions-be so firm as to resist the reducing action of both the brushopeners c and the flexible openers 0 provision may be made for positively loosening such portions to a degree sufficient for reduction by the brush-beaters c by means of rigid openers c of slightly-less-radial projection than the flexible openers c Portions of the cotton passing through the feed mechanism of sufficient firmness to resist the impact of the openers at the point of protrusion into thepath of the said openers may hang over the front edges of the feed-levers 13. Such overhanging cotton is sustained and presented to the further action of the rotating openers by the auxiliary extension-piece fingers b,
-. which, however, yield sufficiently to compensate for variations in quantity of material passing over them, so as to protect the latter against injury.
The pivotal connection 19 between the ends of the levers B and the auxiliary extensionpieces I) may be effected in any desired way. As shown in the drawings, the lower side of the lever'B is formed with a lug b, which fits in a recess 19 of the extension-piece b, and the pivot b passes through the said lug b and the sides b of the recess 1).
In Fig. 2 the openers c c c are supposed for the sake of convenience in illustrating their action upon the cotton fibers to be arranged longitudinally in series upon the face 0 of a cylinder. The adjoining projections O O 0 represent the arrangement of the heaters c c c as related to each other transversely of the cylinder, the several series being placed so as to break joints or intervene with each other in transverse planes. This is also illustrated in Fig. 4, in which the openerbrush 0 is also shown. The same result may be accomplished in practice by the construction illustrated in Figs. 9, 1O, 11, and 12, in which the whipper C is made up of segments 0 each formed with a brush-opener c and a rigid opener 0 which is in the form of a segment of rigid inverted truncated V-shaped or saw teeth. These segments 0 are held in place by longitudinal bars 0, to which are attached the flexible leather openers 0 The relative degrees of radial projection between the several series a c c of openers is substantially the same as that illustrated in Fig. 2, the only difference being one of form and arrangement, while the action upon the cotton fiber is essentially the same. This latter arrangement is susceptible of an important variation in arrangement, however, in that each series of rigid teeth may be placed in a position slightly eccentric to the shaft D, so as to act gradually and gently upon the morefirmly-matted portions of cotton. This fea- V ture is illustrated in Figs. 9 and 11.
The segments 0 are successively arranged slightly one in advance of the other along the shaft D, (say onequarter or one-eighth of an inch,) so as to break joints with each other, and practically constitute a spiral of low pitch extending around the shaft D from one head-piece D to the other D The rotating opener O is supported and inclosed by suitable framework E. It is preferably situated in a chamber F, in which a partial vacuum is maintained byan exhaustfan G, currents of air being admitted at ff, which float the cotton awayfrom the impurities, which latter may be gathered in a settling-compartment, such as indicated at F.
