ROLLER FOR COTTON-GINS.
SPECIFICATION forming part of Letters Patent No. 637,922, dated November 28, 1899.
Application filed November 21, 1898. Serial No. 696,961. (No model.)
To ctZZ whom, it may concern:
Be it known that I, DANIEL SIMEoN CHAPIN, of Milford, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Rollers for Ootton-Gins, of which the following is a description sufliciently full, clear, and exact to enable those skilled in the art to which it appertains or with which it is most nearly connected to make and use the same.
In the practice of the art of ginning cotton it has been ascertained to be an indisputable fact that the so-called roller-gin is preferable to the so-called saw-gin, for the reason, inter alia, that the latter damages the staple at times to an almost-ruinous extent, while the former does not injure it to an appreciable degree. The principal reason why the roller-gin has not been universally adopted has been its relative uncertainty and slowness of action. This and other objections have resulted for the most part, if not entirely, from the imperfections of the roller which carries the fiber into the machine to have the seeds and substances foreign to 'the fiber separated therefrom. It is essential to a perfectly-operating roller that it shall possess structural characteristics in virtue of which n it will readily and with certainty but without injury catch or take hold of the fibers when the latter comeinto contact with the roller, so that the roller may carry the stock through to be acted upon by the seed removing means. Among the qualities of a perfect roller are durability and firmness to a degree that will enable it to maintain a regular surface and at the same time possess features or means which will enable it to immediately and certainly take hold of the fibers coming into contact with it and hold them with a degree of tenacity requisite to properly convey them through the gin, and yet without injury to the staple.
I have ascertained from long, intelligent, and careful experimentation that a roller comprising a body composed of layers or disks of cotton duck or its equivalent and provided at intervals with layers of fiber-catching means such as fine Wires, bristles, or coarser vegetable fibers radially or substantially radially arranged, yet so that their outer ends will protrude beyond the surface of the roller, the whole powerfully compressed and maintained in compressed condition-will subserve the purposes of a perfect gin-roller.
Reference is to be had to the annexed drawings, and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.
Of the drawings, Figure 1 is alongitudinal sectional view of one form of my improved roller for gins and other mechanisms. Fig. 2 is a transverse sectional view, taken on the line 2 2 of Fig. 1, cutting through the body part of the roller. Fig. 3 is likewise a trans Verse sectional view of the improved roller, taken on the line 3 3 of Fig. 1, cutting through a fiber-catchingmeans section of the roller.
In the drawings, a designates the rollershaft, which may be provided with a permanent head I) near one end and a removable and adjustable head 0 near the other end. The removable and adjustable head may be formed snbstantiallylike the head I; and after the efficient or body portion of the roller has been compressed to the desired degree and placed on the shaft may be screwed upon the shaft or otherwise suitably secured thereon.
f designates rings or disks of cotton duck or equivalent woven fiber of which the body part of the roller is formed by the disks be* ing made by cutting or stamping them out of sheets of the woven material and subjecting them to powerful compression, so as to ren .der the mass solid and substantially proof against moisture and so that its surface may be regular and firm.
In the work or process of arranging the layers f of cotton duck for compression, as stated, I incorporate therewith at intervals layers g of what I term fiber-catching means, which means are composed of fine wires, bristles, horsehair, cocoanut fiber, or the like radially arranged and with their outer ends protruding to an appreciable extent beyond the surface of the roller when it is finished.
It is not essential to my invention that the wires or bristles or other equivalent means be arranged in absolutely radial position, since it is necessary only to give them such position that their protruding ends may perform the function of catching the fibers brought into contact with the surface of the roller and carrying them into the machine.
Having; thus explained the nature of the invention and described a way of constructing and using the same, though Without attemptiug to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is- A roller for cotton-gins comprising in its construction round disks or layers of cotton duck powerfully compressed into roll form, as described, and provided at intervals with radially-arranged fiber-catching means, as lengths of fine Wire or bristles, and means for 15 maintaining the layers in compressed condition.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of 20 September, A. D. 1898.
