UNITED STATES PATENT OFFICE..
EMIL J. HUGO, 0F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO LARGMAN, OPPEN- HEIM & C0., OF PHILADELPHIA, PENNSYLVANIA, A COPARTNERSHIP COMPOSED 0F HARRY LARGMAN, JOSEPH LARGMAN, M. OPPENHEIM, AND EMIL J'.
HUGO.
CORD WINDER.
Application led August 22, 1923. Serial No. 658,763.
7,'0 all whom, it may conce/m.' l
Be it known that I, EMIL J. HUGO, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented -a new and useful Im )rovement in Cord Winders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improved device for winding a thread upon a center core for the production of fancy cords, and more particularly my invention relates to an improved support for the spool or bobbin upon which the supply of covering thread is held and from which it is fed for winding upon the center core.
Heretofore the covering thread supply has been wound on a spool or bobbin and the spool supported to freely rotate on a spindle. The thread is led through guides to the center core which passes through the center of the spindle, the thread being drawn from the spool and spool being braked or tensioned by a cord frictionally engaging a Groove in the spool and carrying a weight.
uch devices have proved ineicient primarily because of the inefficiency of the tension device, which requires constant change of adjustment, as the diameter of the body of thread on the spool decreases in size, in order to approximate a constant equal tension. Further, due to inequalities in the tension on the wrapping thread and a certain amount of give and take in the core thread, it is extremely diiiicult to avoid the production of cord havinga wavy effect or in other words cord in which the covering thread is wound unevenly on the core thread.
Now it is the object of my invention to provide a device of the character indicated, in which the covering thread will be under a constant equal tension irrespective of the diameter of the body of thread on the spool and in which there will be no tendency for the wrapping thread to be wound unequally on the core thread.
Having now indicated in a general way the nat-ure, purpose, and advantage of my invention, I will proceed to describe in detail a preferred embodiment thereof, with reference to the accompanying drawings, in Which- F ig. 1 is a plan view of a device embodying my invention.
Fig. 2 is a longitudinal view of the device shown in Fig. 1.
a represents any suitable support for a fixed spindle b upon the outer end of which is detachably secured a conical head c. The spindle is hollow and the thread is provided with a central bore in order to permit the passage of the center core thread d.
A sleeve e, upon one end of which is secured a pulley f adapted to be driven, is slipped over spindle b and is adapted to receive a spool g which carries a supply of covering thread l1., the outer end of which is retained by the neck of head c.
A friction member i, loosely mounted on the sleeve and faced with felt j or other suitable friction is adapted to be yieldingly pressed against the inner end-of the spool and to be driven by pulley f by means of a spring secured to and positioned between the friction member and a head Z carried by the pulley. Thus, the spool is positioned on the sleeve e between the neck of head 0 and friction member z'.
The bearing of the friction member i against the end of the spool may be adjusted by varying the degree of compression of the spring lc by moving the pulley through the medium of adjusting member m secured to support a by means of a wing nut n.
A flyer o, one arm of which is provided with a pulley p over which the thread h passes, is secured to the head Z carried by the pulley and serves to lead the thread from the spool.
The operation of the device will, it is believed, be readily understood. A full spool of covering thread is slipped on the sleeve e after removal of head c from spindle b. The spool is positioned by the replacement of head c and the tension of spring lc adjusted by manipulation of adjusting member m. which is secured by wing nut n. The end of the covering thread 71, is led over the pulley p of the flyer 0 and secured to the core thread cl which is led through the spindle and head and attached to a suitably driven spool upon which it is wound as it is covered.
` mires the rotation of the spool at a speed slightly greater than the speed that is imparted rto it by the frictional drive. Thus, the strain on the thread is minimized.
The covering thread constantly on ltension as described is directed to the core thread over the end of head e and is Wrapped around the core thread at the time when it v emerges from the head. Thus the head serves as a guide for the Wrapping thread during the actual Wrapping operation and the presence of any gap between the core thread and the guide for the core thread and Wrapping thread as it is wrapped is eliminated thus avoiding irregular Wrapping.
It will be appreciated that the particular embodiment of the invention described is susceptible of various modifications and changes- Without departure from my invention.
' Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
l. In a cord Winder, in combination, a loosely mounted spool, a driven member, a friction member adapted to engage the spool` and means affording a yielding connection between said driven member and said friction member.
2. In a cord Winder, in combination, a loosely mounted spool, a driven pulley, a iier positively driven by the pulley, a fric tion disc in engagement with an end of the spool, and a spring secured to said disc and pulley adapted to act to hold said disc in engagement With said spool and afford a driving connection between said pulley and said disc.
3. In a cord Winder, in combination, a. loosely mounted spool, a driven pulley, a friction disc in engagement with an end of the spool, a compression spring secured to said disc and pulley and positioned therebetween and adapted to act to maintain said disc in engagement with said spool and atford a driving connection between said pulley and said disc, and means whereby the tension of said spring may be varied'to vary the degree of frictional engagement between said disc and said spool.
4. In a cord Winder, in combination, a fixed spindle, a sleeve rotatably mounted thereon, a driven pulley secured to said sleeve, a spool loosely mounted on said sleeve, a friction disc loosely mounted on said sleeve and adapted to engage an end of the spool, a spring secured to said friction disc and to said pulley and adapted to act tc force said friction disc against the end of said pulley and afford a driving connection between said pulley and said friction disc.
