SPECIFICATION forming part of Letters Patent No. 783,084, dated February 21, 1905.

Application filed March 4, 1904. Serial No. 196,515.

To (If/, wle/mt it may concern.:

Be it known that I, HARRY SPENCE, a citizen of the United States, residing` at Sanford, in the county of York and State of Maine, have invented an Improvement in Fliers, of which the following description, in connection with the accompanyingdrawings, is aspeciiication, like letters on the drawings representing like parts.

This invention has for its object the production of a novel iiier to be carried by a spindle and used for spinning yarn, more especially yarns having projecting filamentssuch, for instance, as mohair or low-count yarns-that are wound after the manner of the warp-wind on double-headed bobbins.

In spinning yarn with an ordinary iiier, especially mohair, the beard of the yarn projects unduly from the Wound mass near the under side of the upper head of the bobbin and becomes tangled in the Hier-eyes, breaking down the yarn.

The improved iiier herein to be described is for doing away with any injurious tendency of said beard to be caught by the flier-eye and break the yarn.

In accordance with my invention I mount upon the upper end of the spindle a cage having at its lower end a ring that acts on the beard of the yarn above the point where the yarn being wound meets the yarn-load, and consequently when the bobbin starts on its upward journey the beards are depressed, so that they may be caught by some of the layers of yarn first wound under the upper head of the bobbin. Preferably the ring has lugs that engage the flier-legs. The arms sustaining the ring part of the cage are shown as double bars. The central hole of the flier lits over the hub of the cage, and the eyes at the lower end of the flier-legs extend below the ring. This cage also prevents any liability of the flier-legs spreading due to centrifugal action when the spindle is rotated very rapidly.

The particular features in which my invention consists will be hereinafter more fully described, and pointed out in the claims at the end of this specification.

Figure 1 in front elevation shows a spindle containing a flier. Fig. 2 is a section below the dotted line and Fig. 3 is a detail showing the flier-legs removed.

Referring to the drawings, A represents a spindle having a whirl A, to be driven by a band. This spindle has a step A2 in a stationary step-rail B, and the spindle between its ends is revoluble in a bolster or bearing B in the bearing-rail B2. The upper end of the spindle is extended through a hole in a liftingrail O, upon the top of which is laid non-metallic material*suoh, for instance, as leather, and designated by the letter O-and this leather or equivalent material receives upon it a washer O2, of felt. This felt washer and the leather constitute a very effective drag.

The bobbin D has two heads CZ fl. The bobbin is loosely mounted upon the blade of the spindle above the lifting-rail, and the bottom head d of the bobbin rests by its own weight upon the drag, so that the bobbin is rotated .with relation to the spindle by or through the strain of the yarn as it leaves the iiier, to be described, the diiference in rotation between the spindle and its iiier and the bobbin,which is rotated at a slower speed than the spindle, owing to the drag, effecting the winding of the yarn upon the bobbin.

The upper end of the spindle is tapered at and has forced snugly thereon the hub e of a cage comprising a disk c' and opposite double bars c2, that sustain a ring e3. The cage has at its opposite sides dier-engaging devices f, represented as hooks. The hole in the central plate g of the flier, the latter being composed of said central plate and two like legs or arms g', each having an eye g2, is fitted over the hub e, and the legs of the iier are made to embrace the gage, said legs entering the space gbetween the bars @2, the eye giof the iiier-legs terminating a little below the lower end of the ring @3.

Preparatory to starting the frame for spinning' after the bobbin has been applied to the upper end of the spindle the roving is led, as shown, from the draft-rolls through the eye g2 of the iiier-leg' at the right-hand side of the lspindle, it being' immaterial which eye the roving' is led to. The end of the rovingI having some twist is led directly from the liiereye g2 under the ring g3 to the bobbin and is attached thereto in usual manuel'. Usually when the winding is about to be commenced the yarn is wound one or more times around the iiier-legabove the eye, that depending' upon the strength of the yarn and the weight of the bobbin and the tension. Now as the spindle is rotated rapidly the roving' is spun between the drawing-rolls and the bobbin and is delivered from the eye gzdireetly to the surface of the bobbin, and during this action the expansion of the Hier-legs due to centrifugal action is absolutely prevented by the hooks j'. When a 'few layers of yarn have been laid upon the bobbin, the beard or portions of liber that extend from the yarn project unduly therefrom at the under side of the head rl of the bobbin, and if this beard is permitted to stand outwardly the amount of beard, as it is called, increases at each upand-dovvn movement of the bobbin,and finally the Hier-eyes are clogged and the yarn is broken. To obviate this, I have added the ring' c to the lower end' of the cage. During the descent of the bobbin the upper side of the ring' e3 reaches the top of the bobbin in advance of the thread, and the bobbin continues its descent until the ring occupies a position for a distance above the top ol the bobbin suliicient to enable the beard projecting' from the thread at the lower side of the head d to extend outwardly below the lower edg'e of the ring', where it remains until the thread reaches its highest point, at which point the beard is overlaid by the oncoming thread and is secured in the thread mass of the bobbin. Now when the bobbin starts on its upward journey the edge of the ring' immediately acts on the long' libers and turns them down sharply, so that they are caught by some of the lirst windings of the thread about the bobbin und er its head (Z. and the longer beard is thus conlined in the yarn mass.

It will be understood that this flier, although described for use in connection with mohair yarns on double-headed bobbins, may be used for any spinning' and with any class of bobbin, the cag'e having its advantages in preventing the expansion of the flier-legs and enabling' the Hier to be made lighter in weight than heretofore, which is a material object when thousands of iiiers are being employed in the mill, it requiring much less power to rotate them, and the weight carried by the upper end of the spindle being reduced adds materially to the reducing gyration.

I prefer to make the cage of aluminium.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a spinning-machine, a cage consisting of a top having depending arms and a ring at the lower end of said arms, and a flier having a leg' and a delivering-eye from which the thread is led directly under the edge of said ring' to the bobbin.

2. In a spinning-machine, a cage consisting of a top having' depending double arms sustaining a ring, and a flier, the legs of which occupy a position opposite the spaces between said pairs of arms and have their thread-delivering eyes located below said ring whereby said thread may be led directly to the bobbin at a point below the lower edge of said ring.

3. In a spinning-machine, a cage consisting' of a top havingl depending' arms sustaining a ring, and provided with a Hier-leg holder, and a Hier, the legs of which extend below said ring' and engage said leg-holders.

4. In a spinning-machine, a cage comprising' a top disk having a hub, arms depending from said disk and sustaininga ring, and having flier-leg' holders, combined with a flier carried by said cag'e and having its thread-delivering eye located below said ring.

5. A spindle, a bobbin thereon. a cage sustained by said spindle and having a ring at its lower end, and a iiier carried by said cage and having its thread-delivering eye extending below said ring, the latter wiping or laying' down the beard of the yarn as the bobbin starts on its upward journey that the thread leading' from the eye may be wound over and to hold said beard.

6. In a spinning-machine, a revoluble spindle having a cage provided with a ring and a liier having a thread-delivery eye located below the Linder edge of said ring, and means to sustain and move a bobbin vertically with relation to said spindle, the ringl reaching' the top of the bobbin in its downward journey in advance of the thread, the thread being' led from the thread-eye directly to the yarn-load below the lower edge of said ring, to operate substantially as described.

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

- HARRY SPENCE.
