` THOMAS ASHWORTH, OF URMSTON, ENGLAND.

APPARATUS FOR SPINNING AND DOUBLING COTTON.

SPECIFICATION forming part of Letters Patent No. 613,106, dated October 25, 1898. Application filed December 22, 1897. Serial No. 663,045. (No model.) Patented in England October 26, 1894, No. 20,496.

To @ZZ whom it may concern.-

Be it known that I, THOMAS AsHwoRTH, a subject of the Queen of Great Britain, residing at Urmston, near Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Apparatus for Spinning and Doubling Cotton and other Fibrous Substances, (for which I have obtained British Patent No. .20,496, dated October 26, 1894,) of which the following is a speciication.

This invention relates mainly'to a novel construction of iiier for spinning and doubling cotton and other fibrous substances in the form of a cop upon a paper or other tube or spool or upon the bare spindle, the objects of the invention being to obtain a very high velocity without liability to vibration and to regulate the drag upon the spindle so as to produce a perfectly even yarn.

p The nature of my said invention and the manner in which the same is to be performed or carried into practical eifect will be readily understood on reference to the annexed sheet of drawings and the following explanation thereof. T

Figure lis an elevation, and Fig. 2 a section, of a spindle and iiier constructed according to my invention; and Fig. 3 is a section of a modification of the same. Fig. 2 is an enlarged sectional view of a part. Fig. 2b shows in sectional plan spindles and parts of the lubricatingltroughs. Fig. 3a shows an outside detached View of the retainingferrule for the tubular spindle, Fig. 3, drawn to a larger scale; and Fig. 3b is a sectional view showing the ferrule in place.

The improved spindle a, Fig` l, is somewhat like a mulespindle, being parallel or cylindrical in the central portion and tapered at top and bottom, so as to allow of a parallel tube or spool Z) being fitted loosely thereon, so as to grip the spindle, or in some cases I make the upper part of the spindle parallel, or nearly so, and I lighten the same by drilling a hole down from the top, as shown at Fig. 2. The yarn is wound directly onto the tube or spool b, which is doffed with the cop.

The flier consists of a short cylindrical tube c, with a trumpet-shaped mouth or cup 0X at the top Vprovided with a flange d, as shown at Figs. 1 and 2. The trumpet-shaped cup c is formed to fit the nose of the cop, (the base of which is at the top, as shown by the dotted lines,) and at or near the lower end of the cylindrical tube cis fixed or formed a wharve e to receive the driving-band. A notch f (see Fig. l) is made through the flange d of the cup leading to an eye g for threading in the yarn, which runs, as shown in the drawings, so that the cops are spun or wound nose downward in Vthe cup-shaped tubular hier.

The lower end of the flier-tube c fits and revolves inside and is supported by a separate or loose bearing-ringv h, preferably of metal,which itself revolves freely in a recess in the base of the oil-cup t, (see Fig. 2,) the latter forming a portion of a bolste1fX,which is screwed and bolted into the fixed rail 7e of the frame. The lower portion of this bolster is or may be bored out and bushed to t the cylindrical part of the spindle ct, which re* volves and rises and falls therein. The up per portion of the bolster above the oil-cup i (see Fig. 2) is fitted with or forms a long collar, larger in diameter than the spindle a, and iitted at its upper end with a loose revolving ring hx, (see also enlarged View, Fig. 2%) which supports the upper portion of the tubular flier c just beneath the cone or trumpet cx.

The spindle a does not touch the inside of the long collar t'X, there being a space between them, and the outside of the long collar does not touch the inside of the fliertube c, which is carried by the two revolving rings h and hX, above mentioned, so that the friction is reduced to a minimum and at the same time no oil can ascend, so as to damage the yarn.

The bottom of the edge of the wharvee (see Fig. 2) is lower than the top edge of the oilcup t', so as to prevent oil from being thrown out at this point.

Below the bolster X is a rail or bar Z, having a to-and-fro oscillating horizontal motion imparted thereto, which rail may form a hollow trough from end to end or be` provided with a series of oil-holders, (one to each spindle,) as shown in plan view at Fig. 2", and near to each spindle is formed a notch from which projects a loop or wick m, which is always kpt lnoistened by the oil in the trough or rail Each time the rail Z moves to and fro it applies the oiled wicks m to the spindles a, and thus lubricates them, and this wick m also acts as a drag in the following manner: The to-and-fromotion of the rail or bar Zis so regulated that the loops of wick are pressed against the spindles a. at the moment when the yarn is being wound onto the largest diameter of the cop and are grad ually withdrawn as it reaches the smaller diameter, so that the drag is always proportioned to the pull of the yarn. To make this action more certain, I prefer to place a light spring m at the back of each loop. (See Fig. 2b.)

Above the lifting-rail n I also fix, on the lower part of thespindle a, an elastic wing or vane o, Fig. 2, preferablyof india-rubber, which is so formed that it may be sprung or forced onto the spindle and :readily removed or changed when required. This forms an atmospheric drag to regulate the speed or drag of the spindle.

When commencing a fresh set of cops, the spindle CL is in its lowest'position and the base of the cop is wound on the upper part of the tube b, inside the trumpet-mouth cX of the flier. As the spinning or doubling proceeds the spindles a rise up and the cop is built downward on the tube or spool b, the nose of the cop being inside the cup 0X.

When the dofng takes place, the end of the yarn becomes wound around the point of the spindle, and when the fresh tube or spool is placed thereon it holds the end tightly and breaks it oif the cop. I prefer to fix a small brass ring or ferrulep (see Fig. 2) on the spindle a to support the lower end of the tube or spool b.

Fig. 3 shows how by a slight modification this invention may be adapted to frames provided with tubular spindles ctx, revolving around fixed studs or pins p. In such a case I prefer to provide the lower ends of the tubular spindles with flanged rings q to bear against inwardly-hanged ferrules g, Figs. 3f and 3b, which are provided with bayonet-slots to engage with retaining-pins q2 in the footsteps r and so prevent the tubular spindles from being lifted when dofng the caps.

I claim as my invention- A spinning or doubling machine, provided with a tubular flier, having a cup or trumpet shaped mouth at the top for spinning or winding cops nose downward, in combination with a fixed collar or bolster, formed with an oil- Cup, bearing-rings at the upper and lower parts of the bolster to carry the iiier which is provided with a wharve to receive a drivingband, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOS. ASIIWORTII.
