WILLIAM E. IVHITEHEAD, OF LOWELL, MASSACHUSETTS, ASSIGNOR TO THE VHITEHEAD & ATHERTON MACHINE COMPANY.

CARDING=MACHINE.

SPECIFICATION forming part of Letters Patent No. 271,558, dated January 30, 1883,

Application filed August 29, 1882.

To all whom it may concern:

Be it known that I, WILLIAM E. VVHITE- HEAD, of Lowell, in the State of Massachusetts, have invented certain new and useful Improvements in Oarding-Machines, of which the following is a specification.

It is customary to make the carding-cylinder of carding-machines of a length somewhat less than the distance between the sides or arches of the machine-frame. is that the cotton fly is liable to collect on the edges of the cylinder during the operation of the machine, and if the ends of the cylinder come close up to the arches the cotton-fly will rub against the latter with sufficient friction to strike fire. By making the cylinder of such a length that at each end it will be separated from the arches by an appreciable interval or space, liability to accident from the above cause is removed; but the consequence of leaving these end intervals or spaces is that a portion of the cotton works off from the ends of the cylinder and appears on the doffer in small rolls, about the size of walnuts, which are carried along with the. sliver and make had work. The same trouble is experienced on the lickers-in as well as on the dofi'er, and this defect is found in all carding-machines, and is a serious one for manufacturers, as the bad effect of the inferior work done by the machine is apparent in the cloth made from the product of the machine. The object I have in view is to remove this defect, and after considerable experiment I have succeeded in doing so. Y

()n a carding-machine there is of course an opening in the shell or case that surrounds the -main cylinder at the point where the dofi'er comes, and also at the point where the lickersin are situated. It is at these points that the cotton blows out and-appears on the doffer and lickers-in in the objectionable form above noted. I-have found that the difficulty can be completely removed by applying at these openings side lips or flanges, termed by melinings, each of which is fastened to the side of the frame and projects therefrom'laterally, so as to extend over the edge of the contiguous end of the cylinder about one-fourth of an inch. These linings thus cover and in effect stop up The reason for this, trouble are those above specified, and the apmarket.

(No model.)

the exposed portion of the side spaces or passages intervening between the ends of the cylinder and the arches of the frame. They act to prevent the cotton from collecting on the edges of the cylinder and from being then transferred to the doffer, 850. The linings might be continued farther around the cylinder; but this, however, would not be necessary. The only places where there is any plication of the linings to these points is effective to suppress that trouble.

Toenable those skilled in the art to understand and use my invention, I proceed to describe the manner of carrying it into effect by reference to the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of so much of a carding-machine as needed for the purpose of explanation. Fig. 2 is a diagrammatic end elevation, partly in section, of a portion of one side of the machine, with a view to represent more clearly the position occupied by the side guard flanges or linings with reference to the doffer, lickers-in, and carding-cylinder.

A is the carding-cylinder; B, the frame or casing; O, the doffer; 1), the lickers-in, which in this instance are on the same side of the machine as the doffer; E, the lap-roll; F, the topflats. These parts are of ordinary or suitable construction, and in their arrangement and combination differ in no essential respect from like parts of known carding-engines now in the There are the usual openings in the frame at the points where the doffer and thelickers-in come opposite to the cylinder. At each end or side of each of these openings is a lip or flange, G, hereinbefore termed by me a lining, which is a strip of some suitable material of a length equal to the distance which separates the top and bottom edges of the opening in the case to which it is applied, and curved so as to conform to the curvature of the cylinder.

Each lining is attached to the inside face of one of the sides of the frame, and projects laterally therefrom, so as to lap, the adjoining end of the carding-cylinder being of such width, 100

preferably, as to extend over or beyond the edge of the cylinder about a quarter of an inch. The wire card-teeth do not come to the ends of the cylinder, (letter, and lickers-in, there being from one-quarter to three-eighths of an inch of the clothing at each end that has no wire in it. The linings or flanges G project over this bare portion of the clothing, so as to nearly touch it. In this way the passages or spaces between the ends of the cylinder and the side arches of the frame are bridged over and closed at the points where the openings for the dofler and lickers-in are formed in the frame. In this simple way I completely suppress the objectionable feature hereinbefore referred to as attending the working of ordinary carding-machines.

I am aware that it has been proposed to apply to the ends of rollers of carding-machines covering-disks attached to the frame, and provided with annular peripheral flanges to 0verlap the ends of the rollers. This expedient,

which would be ineffectual for the purpose I have in view, I of course do not claim.

\Vhat I claim as new and of my invention is- 1. The combination, with the machine frame' or casing, the carding-cylinder, and the dofier, of laterally-projecting guard flanges orlinings applied to the side edges of the openings in the case or frame through which the dotfer works, so as to overlap the ends of the cylinder and to bridge and cover at that point the spaces or passages intervening between the ends of the carding-cylinder and the sides of the frame, substantially as and for the purpose hereinbefore set forth.

2. The combination, with the cylinder, doffer, and liclrers-in of a carding-machine, of guard flanges or linings applied to and projecting laterally from the frame, so as to overlap the edges of the carding cylinder and bridge and cover the spaces or passages intervening between its ends and the sides of the frame at the points where the dofier and lickersin are situated, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand thi. 21st day of August, 1882.
