FLYERS FOR TEXTILES MACHINES March 22, 1960 Filed March 1, 1957 Unite States Ptent Claims priority, application Great Britain March 24, 1956 3Claims. ((157- 116) This invention relates to flyers, particularly for use in uptwisting machines using double flanged bobbins. The

flyer to which the invention relates is of the type comprising a metal cap having a rolled over edge which revolves coaxially around the upper flange of the bobbin, the yarn guide being located in the rolled over edge.

The object of the present invention is to provide improved means for controlling the amount of resistance to the rotation of the flyer by the bobbin upon which it rests.

The invention comprises the interposition between the flyer cap having the yarn guide carried thereon and the top of the yarn bobbin which revolves with the uptwister spindle, of a plate or disc having a felt or other friction material secured upon its upper face which supports the cap and an India rubber or other'friction pad secured to its underside which rests on the upper end of the yarn bobbin, the cap having a spindle detachably secured thereto which projects downwards and revolves within a sleeve like portion of a member which is free within the upper end of the uptwister spindle.

The accompanying explanatory drawing is a sectional view of a yarn bobbin with its driving means and of the flyer which revolves about the upper end of the bobbin, showing one form of my improved means for controlling the rate of rotation of the flyer relatively to the bobbin.

The spindle by which the bobbin a is revolved comprises a spindle blade 12 and a flange b which has pegs c thereon extending into holes in the bobbin flange d so as to drive the bobbin. In the example illustrated, there is an adaptor bushing e between the spindle blade b and the bobbin a.

The flyer, which is of the type described in my prior application No. 469,698, now Patent No. 2,838,904, comprises a metal cap f, in the peripheral edge of which is secured a yarn guide g. Such cap is usually made of aluminum and in the example illustrated there are metal plates h and i secured to the upper and lower sides of the cap. A spindle j is secured to the cap by a nut k, and such spindle revolves within a sleeve like part m, which has a flange n adapted to rest on the top of the spindle blade b, and a bushing 0 secured in the top of the blade, and a part p which extendsinto the spindle.

A balloon spring q extends between the part p and the service positions. When it is desired to Withdraw the flyer and associated parts from the spindle, a sharp pull on the flyer will cause compression of the balloon spring q so that it will pass through the bushing 0 and allow the said withdrawal.

Disposed around the member in but relatively free therefrom is a plate or disc 1, to the underside of which a pad u, preferably of India rubber, is secured and to the upperside of which a pad v, preferably of belt, is secured. The pad u rides on the top of the bobbin a and the plate i on the underside of the flyer rides on the padv.

It will be appreciated that the bobbin a tends to revolve the flyer f due to the friction between the bobbin and the pad u and the friction between the pad v and the disc i secured to the underside of the flyer. The strength of such frictional drive can be varied by using different materials for the pads u and v and/or by adjusting the weight of the flyer. This can be effected by using different weights or thicknesses of the plates or discs h and i.

When the device is to be placed in position initially, the part m with p and ballon spring q are placed in and on the spindle b and'bush 0; and the spindle j, without the flyer f, pads u and v and the nut k, is placed in the part m, when the washer r and split spring ring r are secured in place. The plate t with its pads u and v is now placed in position. The flyer is then placed on the spindle j and the nut k fitted to secure the flyer to the spindle j.

What I claim is:

1. An improved flyer driving arrangement for use in an uptwisting machine comprising, a rotatable spindle driven by the machine and having an opening extending axially inward from its free end, a yarn bobbin mounted on the spindle for rotation therewith and extending axially beyond the free end thereof, a flyer cap having a guide thereon mounted on the outer end of the bobbin, a pin secured centrally of the flyer cap and extending into the spindle opening, and means for driving the flyer cap from the bobbin comprising a disc having a pad of friction material secured to its underside which rests upon the bobbin and a pad of friction material secured to its upper side on which the cap rides, the said pads being of different texture and different surface area.

2. An improved flyer driving arrangement in accordance with claim 1, in which the pin is detachably secured to the flyer cap, and means on the pin for securing a metal plate to the flyer cap for engagement with the friction pad on the upper side of the disc.

3. A flyer as claimed in claim 2, in which the friction pad on which the flyer cap rides is made of felt and the friction pad which rides on the bobbin is made of rubber.
