?etented Aug 4, i931 I serene ELLIS HARTLEY, @F WHITINSVILLE,'MASSACHUSETTS, ASSIGNOR T WEITIIQ' CHINE WQLELKS, 9h WHITINSVILLE, MASSACHUSETTS, A GOBPQRATION 01" FEASSA- CHUSETTS APZPAPATUS FOR SPIN'IJING YARN Application filed March 4,

This invention relates to apparatus for spinning yarn and more particularly to the yarn spinning apparatus shown and do? scribed in my prior Patent No. 1,839,408, issued August 16 192?.

It is the object of my invention to improve the apparatus therein shown by the provision of an annular ilange or guiding memberbelow the spinning ring, by which provision the yarn is more effectively guided to the bobbin and the use of an open type traveler is facilitated l/ly invention further relates to arrangenients and combinations of parts which will so hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which Fig, l is e sectional side elevation oi? parts of e spinning frame embodying my improvements; and

Fig 2 is as sectional side elevation of the cop and associated parts on an enlarged sealer Referring to the drawings, l have shown parts of e spinning frame in which a plu v relitv ct spindles 10 are mounted in a fixed spindle rail 1. The spindles 10 are normally held in fixed position but are adjustable vertically, being provided for-this ur-nose with a helical groove 13 in which the rounded point of a set screw id is seated. By turning the spindle engularl the vertical adjustment thereof in either direction is accom- .plished,

Bobbins l? are supported on spindle whirls 16, mounted on sunports 17 carried by the bobbin rail 18. The whirls 16 are freely rotatable about the axes of the spindles l0 and are movable vertically ,with the bobbin rail 18.

Cups 26 are mounted on the'upiper ends of the spindles ill and are each provided with a denending conical portion encircling end largely enclosing the bobbins B. The construction thus for described is usual in a cap spinning frame.

A collar 22 is threaded on the lower end of the cap 20 andfiovides a support for a spin ning ring .24 w 'ch is clamped on the 6011211 1930. Serial No. 433,113.

22 by a locking ring or nut 26. This construction is along lines similar to that disclosed in my prior patent above identified.

An open type traveler T is mounted on the spinning ring 24 and guides the yarn as it is drawn downward from feed rolls through a yarn guide or eye 32. The traveler T is preferably of the type shown and described in my prior Patent No. 1,746,154, issued February 4:, 1930.

My present invention relates particularly to the provision of an annular guiding memher or flange 40 mounted below the ring Preferably the guiding member 40 is clamped between the conical lower portion 42 01? the collar 22 and the conical inner -face 44: of the ring 24. The lower part of the guiding member 40 is in the form of an outwardly and downwardly inclined flange which projects below the path of the traveler T. '7!l0 it will be seen that the locking ring 26 serves not only to hold the ring 2din position, but also clamps the guiding member 40 securely between the collar portion 42 and the ring surface 4 1-. Furthermore, the pressure of the locking ring contracts the slotted lower loortion of the collar 22, causing it to firmly grip the threaded outer surface of the cap 20,

The extreme lower end of the cap 20 is left so smooth and unthreaded and is carefully finished to provide on additional guiding surface for the yarn on its path from the traveler 'l to the bobbin B.

By the provision of the guiding member 40, the effective operation of this type of cap spinning apparatus is much improved and all difiiculty of unthreading the open type traveler is avoided. Furthermore, by p providing the ring and traveler in combina tion with the guiding flange at the lower end of the cap 20, it is found possible to wind the yarn much more closely on the bobbin B and to thus increase the amount of yarn $5 on each bobbin, correspondingly increasing the run of the bobbin.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, 1m]

otherwise than as set forth in the claims, but 1181? I claim is: t h L as mm a ara usv avmg a mdle abobbih mou nte d thereon and rota table and axially movable relative thereto, and a cap mounted on the upper end of said spindle and depending about said bobbin, in combination, a splnning ring mounted on said cap and adjacent the lower end thereof,

' and a separate and additional annular arn guidin member mounted on said cap an positioned below and adjacent said ring, the yarn guiding portion of said member havmg a diameter as, large as the diameter of the largest part of said rin and enga 'ng the yarn at a point substantia y further gem the axis of the cap than the lower edge of said (gag.

2. e combination in a spinning appago ratus as set forth in claim 1, in which the outer portion of the guiding member is outwardly and downwardly inclined. 3. The combination m a spinning apparatus as set forth in. claim 1, in which a collar is provided on the cap on which the ring is mounted, and in whlch the guiding member is clamped between the collar and the ring. 4. The combination in a spinning appa- 3 ratus as set forth in claim 1, irf which the guiding member\-has an outwardly and ownwardly inclined portion underlying the path of a traveler mounted on said ring.

5. The combination, in a spinning appa- 3 ratus as set forth in claim 1, 1n which a collar is provided at the lower end of the cap, said collar having a conical lower portion, and in which theguiding member is clamped against said conical collar portion and extends outwardly and downwardly to underlie the path of the traveler mounted on said' ring.

In testimony; whereof I have hereunto affixed my signature. 3 ELLIS HARTLEY.
