TOP DRAWING-ROLLER FOR SPINNING-MACHINES, 86C- SPECIFICATION forming part of Letters Patent No. 363,035, dated May 17, 1887.
Application filed Decemhtr 13,1856. Serial No. 221,349. No model.)
To all whom, it may concern.-
Be it known that 1, Joan W1LcocK, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvcment in Top Drawing-Rollers for Spinning- Machincs, &c.; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making part of this specification.
My invention relates to machines for drawing, roving, and spinning cotton and worsted yarns, &c.; and it consists in an improved top drawing-oil" roller for such machines.
As is well known in machines employed in the process of drawing, roving, and spinning worsteds, &c., an important and material part of the machine is the drawing-rollers. Frequently there are employed in the said machines or frames a set of metal rollers through which the roving passes before being drawn. After passing through these rollers the pro cess of drawing out the roving takes place, and in order to accomplish this end a set of rollers, which we. will designate the upper and lower, are employed, which said rollers, revolving faster than the roving is fed from the bobbin or reel, consequently draw the material into a smaller thread and out to greater length; but in order that, as neces sary, the drawing off rollers shall take hold of the roving, a peculiar construction of such upper and lower rollers is necessary. The lower or under roller is usually of metal, having a fluted surface or circumference.
Heretofore the upper roller (in most general use) has been a device constructed of wood or metal, generally wood, having, in order to accomplish the necessary friction, a layer or two of leather or cloth, or both, fastened around its surface or circumference by tacks, glue, or other means. Between the two drawing-rollers the roving passes, and is thus drawn out to the required extent, as regulated principally by the relative speed of the rollers and the yarn as fed. v This brief general summary of the particular part of the processes of drawing, roving, and spinning which has relation to my improvement is given. in order that the application of my invention to the machines may be the better understood. In those rollers which e1n ploy the leather or cloth covering difficultyis experienced in the leather or cloth, 850., covering of the surface of the top drawing-roller coming off, wearing out, rotting, &c., while in a solid composition roller the yarn is very frequently cut and broken-as when an irregnlarity occursthere being no give to the roller.
The object of my invention is to provide a roller so devised and constructed of such material that these and other difficulties heretofore experienced shall be obviated, abctter result attained, and less power required to drive the machine. The replacing of the leather or cloth coverings when worn out or displaced requires the employment of skilled labor, and, besides this expense involved, occasions the stoppage of the machine and much delay in the process of manufacture. The coverings are required to be replaced and readjusted every few months. In many rovings in which there is considerable grease and dirt remaining the constant contact with the roller-coverings saturates and then rots them, so that they require more frequent replacing.
1 will now describe my invention, so that others skilled in the art to which it appertains may apply the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents in front view two of the upper or top drawing-rollers applied to the shaft or arbor, having the side plates fitted thereto. Fig. 2 is a side view showing the composition-shell and a side plate, and indicating by dotted lines the rubber center applied to the shaft, and a portion of the supporting bracket or device being also shown. Fig. 3 shows a sectional elevation of the parts shown in F1 2 in detail. Fig. 4 is a general View of a series of top rollers placed as in the machine, in contact with the under or metal fluted rollers.
Similar letters of reference refer to similar parts throughout.
In the drawings, A represents the shell or composition portion of the top drawing-roller affixed to the arbor or shaft 2) by means of the plates 0 c. The center of the roller is provided with the filling or cushion d, made of rubber or other elastic material, which, being firmly fitted into thecut out center of the roller, is in turn applied to the shoulder i of the plate 0. The plate 0 is firmly affixed or fitted to the shaftb, being keyed or shrunk thereto, or by other desirable means. The plate 0, being firmly fitted to the shaft 1), the composition shell A is securely held in position by the plates 0 0', screws 9 passing through and being screwed into the plate 0, as shown. Slots Z are provided in the composition shell A, in order that the screws or bolts when the rubber filling or cushion gives by reason of the pressure brought to bear in the process of the operation, may play up and down in the slot. Otherwise the roller would be rigid and the function of the rubber cushion remain unperformed.
The letter f in Fig. 4' represents the metal fluted or under roller. h is the bracket or bearing of the shaft or arbor b.
The roller A is composed of paper,or a composition of which the principal ingredient parts are paper and cement, or vegetable fibers chemically treated, and does not require any covering on its surface whatever, as heretofore, and will, to all intents and purposes, never wear out, and produces a saving in steam-power, in that it does not require as great a power to run the rollers as in the old system. By reason of the cushion of rubber or other elastic material fitted into the center of the'roller an evenness and uniformity of motion and of pressure are attained.
Although the leather-covered rollers which I have described are the best known and in universal use, yet I am aware that heretofore there have been other rollers invented for like capable of giving when any irregularity or unevenness occurs in the yarn or thread. Otherwise the yarn would be likely to be cut, and if the'material or composition employed for the working-surface should be of a wearable and yielding material grooves will be worn therein by the constant passage of the yarn or thread and irregularities will occur;
My invention as herein described is in a drawi ng=roller having a hard durable composition shell or working-surface provided with a center composed of a yielding giving material, the whole being secured to the arbor or shaft by the plates.
Having thus described niy'inveniion, what I claim, and desire to secure by Letters Patent, 1s-
In a drawing-off roller, a composition shell or working-surface, in combination with a center of rubber or other elastic material, the arbor or shaft, and the plates, substantially as herein setforth and described.
In testimony whereof I have hereunto set my hand this 11thday of December, A. D.
JOHN XVILOOCK.
