UNITED STATES KURT n. THIERFELDER, or MILWAUKEE, WISCONSIN.
PORCELAIN THREAD GUARD FOR CONES.
Application filed January 28, 1925. Serial No. 5,285.
To all 'whom t may concern:
Be it known that I, KURT E. THIERFELDER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of lilisconsiii, have invented certain new and useful improvements in Porcelain Thread Guards for Cones, of which the following is a specification.
My invention relates to porcelain threadguards for cones, such as are commonly used in the textile industry; these thread-guards being used when the thread is spun from the cones onto bobbins, or direct from cone or bobbin to the machine making the fabric.
The object is to provide a guard for the end of the cone, which will be securely held thereon, and which will prevent the thread from getting broken, or from being unduly jerked during the unwinding process; and which will yet permit the thread to be unwound very rapidly, without any interference.
The cones herein referred to are commonly used over and over continuously on coning machines where the silk is first coned and then run oif onto bobbins.
The silk when being coned, is coned or wound to within about an inch from the top of the cone, as illustrated in the drawings. The silk is then spun from the cones onto bobbins, and in this process travels very fast. As the cones are commonly made of paper, and are used continuously over and over again, the small ends of the cones very frequently become torn, cracked or broken, so that the thread as it swiftly travels past the end of the rapidly revolving cone, often hangs and is broken. In fact the outer periphery of a cone is purposely made somewhat rough, and the end of the cone, due to the great compression applied at that point during the manufacturing process, is apt to be a little rougher and more irregular on the outer surface than the rest of the cone, so that even when the cones are new, the thread is at times caught on the end of the cone and broken; and of course, when a break occurs, the cone must be stopped and the silk re-knotted, and the knot eventually makes a bad place in the weave. Moreover, with a rough or raggedended cone, the thread has a tendency to jump or jerk, causing uneven winding on the bobbin and uneven tension in fabric. Also with rough and damaged cones which cause breakage, there will always necessarily be a certain amount of rewinding of pieces of yarns which could not be used from the original cones. Thus there arises both eXtra labor and delay, in addition to the loss occasioned by damaged goods.
My invention overcomes all of the above diificulties, permitting a very rapid rotation of the cone, and also giving an unbroken thread free of knots, evenly wound upon the bobbin, with no fragments of threads left on the cones.
The invention consists in the novel construction and arrangement of the guide relatively to its use with the cone, as will be now described and claimed, reference being` had to the accompanying drawings in which Fig. l is a side elevation of a cone provided with my improvement, the cone having thread wound thereupon ready to be spun onto a bobbin: and,
Fig. 2 is a sectional View of a cone with my improvement thereon.
My device is formed preferably of porcelain, and comprises the outer shell or cap portion l having the interior central pin 2 formed integral therewith. The outer or cap portion l has its outer periphery gently curved longitudinally, as indicated at la, and its inner periphery lb is slightly tapered like the frustum of a cone. Attention is, however called to the fact that the degree of taper is slightly less than the taper of the cone, so that the cap will grip the cone the tightest at the lower end of the cap.
The central pin 2 lits the opening 3 in the end of the cone. By this arrangement, the compression of the inner periphery lb of the cap on the outer periphery of the cone will tend to press the walls of the opening 3 of the cone into firmer engagement with the pin 2. Hence my device is adapted to be very securely held on the end of the cone, and can be instantly placed thereon or removed therefrom with perfect ease, when desired.
The cap 1 is also provided at its lower end with the peripheral bevel l", which deflects the thread away from the whirling cone and thus gives a free and uniform delivery of the thread to the bobbin, or knitting machine, instead of frequently catching the thread on the rough surface of the cone adjacent the cap and winding it under the end of the cap, as would otherwise be the case.
The guide fits snugly over the top of the cone, forming a shell-like cover which prevents the silk from abrading contact with the rough top-end of the cone.
The annular pressure of the inner peripheral walls of the cap on the outer periphery of the end of the cone, tends to compress said end, and causes it to more firmly grip the central pin 2 of the cap, and will do this even when the end of the cone is somewhat cracked or otherwise marred. Hence my device often permits the use of cones that would otherwise be entirely unfit for use.
The walls of the cap may be made considerably thinner than is shown in the drawings, and still be strong enough not to be liable to breakage from falling. made as heavy as shown they will stand any amount of rough and careless usage with safety.
The central pin 2 of the cap could be made slightly conical with the smaller end downward, so that it would have a wedge-like contact with the opening 3 of the cone; but that would tend to enlarge the opening, and would promote cracking and splitting. But with that pin formed of even diameter throughout, and the inner peripheral wall lb of the cap inclined, all as shown in the drawings, the opening 3 in the cone will always be pressed into tight engagement with said pin 2, without said opening becoming appreciably enlarged even with long and continuous use; and in order to insure the perfect operation of the device in this respect, the cap is made sufficiently long to provide the vacant space ld in the top thereof. In use the cap will be made as long as will be found most advantageous.
But when The operation of the device is apparent from the foregoing, and when slipped on the end of the cone as shown in the drawings, is ready for use.
Having now described my invention, what I claim as new and desire to protect by Letters Patent is l. In a device of the character described, a cap having an internal, longitudinally extending central pin adapted to extend into the opening in the end of the cone with the body of the cap adapted to fit over the smaller end of the cone and arranged to press the walls of said end toward said central pin; whereby to simultaneously set up a binding engagement between the central pin and the end of the cone, and between the cone and the body of the cap.
2. In a device of the character described, a cap adapted to fit over the smaller end of a textile cone; and having a truncated coni cal inner periphery; and an internal pin of uniform diameter at the axial centre of the cap, and of a size to lit the opening in the end of the cone.
3. In a device of the character described, a cap adapted to fit over the smaller end of a textile cone; and having a truncated conical inner periphery and a bulged outer periphery; and an internal pin of uniform diameter at the axial centre of the cap; and of approximately the depth of the cap and an annular external beveled section at the open end of the cap between said end and said bulged section.

In testimony whereof I affix my signature.
