AUTOMATIC SELF-CENTERING GUIDE EYE Filed Aug. 4, 1957 Patented Sept. 13, 1938 UNITED STATES PATENT OFFICE John J. Dunleavy, Scranton, Pa.

Application August 4,

14 Claims.

This invention relates to thread guiding devices such as are used in the textile art in connection with various types of winding machines.

The principal object of the invention is the pro- Vision of a self-centering guide used in connection with the winding of yarn and thread, principally silk and rayon yarn, and by the use of which pile yarn windings at the spool heads are eliminated.

A further object is the provision of an automatic self-centering guide eye provided with a projecting feeler arm which when it contacts with the spool head releases the guide eye member from the action of the traverse bar and wherein the guide eye is again automatically connected to the traverse bar and properly centered.

A further object is the provision of a selfcentering automatic guide eye by the use of which a more even wind is obtained through the winding of thread or yarn particularly silk or rayon yarn and wherein any bulging of the yarn at the heads of the spools is eliminated.

A further object is the provision of a device of this character wherein a more even tension with a better wound spool of yarn or thread is attained and wherein in operation the yarn is in contact only with the usual standard porcelain guide eye carried by the guide eye clamp or holder.

A further object is the provision of a device of this character wherein proper centering of the yarn is always maintained and piling up of the yarn at the head of the spool is prevented.

Heretofore in guides of this character in this art it has first been necessary to ascertain the proper position and location of the guide on. the traverse rail and after such position is ascertained the guide is adjusted along the traverse guide rail and set and remains fixed during the operation of winding.

My invention is the first wherein is provided an automatic self-centering guide eye for use in winding yarn or thread in winding machinery.

My self-centering guide eye is shown in the accompanying drawing, wherein corresponding sponding parts in each of the several views.

In the drawing:-

Fig. 1 is a plan view of my device showing same attached to the traverse rail and as used in connection with the spool on which the yarn is being wound;

Fig. 2 is a rear face view of the device;

I4, through which is passed a pin or rod I5. The 1 base plate I6 is rigidly secured to the traverse rail IT by means of screws or other fastenings I800, that the guide I2 is caused to move with the traverse rail," in both directions. On the inner edge of the plate H5 at each end is provided a loop or socket Ma which carries the pin I5. The loop or socket I4 is shorter than the distance between the loops |4a to allow for a sliding or lengthwise movement or play of the guide I2 when the feeler arm or projection 2| contacts the head 24 or 25 of the spool. Projecting downwardly from the plate I3 from the front thereof is a portion l8 formed from the metal plate. The lower edge of this downwardly projecting portion is provided with teeth or indentations I9 in which enter upwardly extending projections or teeth 20 on the base I6.

It will thus be seen that when the teeth 20 are in mesh with the teeth I9, the guide eye will be carried along with the traverse rail in whichever direction the same is moving.

Projecting inwardly from the portion I8 is a feeler arm or projection 2| which, in the present instance is made adjustable as to its length by passing the inner end of the arm through an opening in the plate l8 and downwardly extending portion 22 of the plate l3. A spring 23 is interposed between the plates 22 and I8 which normally holds the arm 2| projected outwardly.

The feeler arm 2| is made adjustable in order to take care of filled or partially filled spools and is automatically shortened as the mass of yarn on the spool increases.

It will thus be seen that when the feeler arm 2| contacts with the head 24 or 25 of the spool, the spool revolving, due to friction the guide with its clamp will be pivotally moved on the pin or rod I5 and released from the plate I6, which is carried by the traverse rail, and moved along the rod, and automatically returned by gravity, into proper centering position, when it will drop and again mesh with the teeth 20 and when the traverse rail starts in the opposite direction and reaches the head 25 of the spool, if piling of the yarn is likely to occur, the same operation will be performed and the same action take place.

It will thus be obvious that by the action of my self-centering automatic guide and the operation thereof, piling yarn windings at the spool heads will be eliminated.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. In a device of the character described, a traverse guide rail, a self-centering guide eye pivotally and slidably mounted thereon and movable therewith, means normally holding said guide eye against sliding movement on the rail, a winding spool for the yarn, and means adapted to contact with the head of the spool and cause said guide eye to swing on its pivot and thereby automatically disconnect said guide eye from movement with the rail.

2. In a device of the character described a traverse guide rail, a winding spool, a self-centering guide eye slidably and pivotally mounted on the rail and movable therewith, means holding said guide eye against sliding movement on the rail, a contact arm on the guide eye adapted to contact with the head of said spool and automatically disconnect the holding means to permit of relative movement between the rail and the guide eye. a

3. A device of the character described for winders, comprising a thread guiding member, a plate, means carrying said thread guiding member pivotally and slidably mounted on said plate, means on said first mentioned means cooperating with means on said'plate for normally holding said thread guiding member against sliding movementon the plate, and means for releasing said holding means to permit of relative movement between the plate and thread guiding member.

4.
