UNITED STATES CHARLES W. YOUNG. OF KILLINGLY, CONNECTICUT.

TENSION-CONTROL INDICATOR.

Application filed February To all whom it may concern:

Be it known that I, CHARLES W. YOUNG, a citizen of the United States of America, residing at Killingly, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Tension-Control Indicators, of which the following is a specification.

This invention relates to indicators adapted to be placed upon twisters or any-other machines where yarns are twisted from beams upon spools or any other similar devices, so that lf there is too great or too little tension upon the strands of yarn, which are being twisted from the beam or other apparatus upon spools or any similar device, the indicator will register the fact so that the tension may be regulated properly.

After yarns are spun, they are run upon beams and there may be a large number of ends of yarn upon a single beam. These beams may then be put upon twisters and a certain number of ends of single yarn are taken from the beam and twisted and wound upon a spool or other similar device, so that from one beam there may be numerous ends of yarn being unwound at the same time upon numerous spools or other similar devices. As the beam unwinds, there has to be suflicient checking of its speed, by friction applied or otherwise, so that each end will be kept taut as it is unwound; otherwise, the yarn will kink or snarl. I-Iither' to, there has never been any process for measuring the tension of the yarn as it is 1 being unwound from the beam, and if too great tension is applied, it stretches the yarn so that when it is woven into a fabric or otherwise used it willbe weak and not of as great strength as it should be. This is especially true of yarn which goes into fabrics that are used in the manufacture of automobile tires, as the greatest strength possible is needed in such fabrics, whether it be a closely woven fabric or the cord fabric, so called. To aid in producing a uniform tension on the ends as they are unwound from the beam, there has been disclosed in this a lication the tension control indicator w ich will indicate any in- 18, 1925.

crease above or decrease below the normal or proper tension, so that friction upon the beam may be immediately .lessencd or increased and the tension at once restored to normal. I

Otherobjects and advantages of themvention will be apparent during the course of the following description. I

Figure 6 is a detail perspective view of the main stand bracket, formin a part of the tension control indicator, ancI I Figure 7 is a fragmentary perspective view of a tension lever which forms a part of the indicator.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates in its entirety a twister, or other similar machine, which employs a tension or rock bar 6, shown in detail-in Fig. 2.

This tension or rock bar 6 is formed of wood and consists of a hexagonal body portion 7 and journal portions 8 at the ends thereof. The hexagonal body portion 7 is provided with a row of wire eyelets 9 which may be provided in any desired number and spaced any suitable distance and are employed for having the ends of yarn passed therethrough from a. beam, upon which the yarn is wound, but which is not shown in this case, to the spools carried by the twister. This tension or rock bar 6 is journaled in the frame of the twister, shown in dotted lines and designated by the numeral 5.

The tension lever 10, shown in detail in Fig. 7', is provided with a clamp structure 11 at one end by means of which the lever may be secured to one end of the tension or rock bar 6 so that rotation of the bar in either direction will cause similar movement of the tension lever. This lever is provided with a depending, L-shapedextension 12' havin the foot portion 12, as best illustratedinFig. 7.

The extremity of thetension lever 1s: pro vided with an aperture 13. by means of which the weight 14 is fastened to the. lever.

Arranged in respect to the twister 5, as best illustrated in Fig. 1, is astand 15 having mounted on the upper end thereof a substantially U-shaped main stand bracket 16, as illustrated. This bracket is rovided with two pairs alined

openings

1 and 18 respectively, as best illustratedin Fig. 6.

A pinion stud 19isjournal'ed in the openings'l'. and is retained in place bythe collars 20*." This pinion stud has suitably keyed thereto a pinion 21 which meshes with the segmental gear 22 keyed to the rock stud 23 journaled in the apertures 18 formed in the main stand bracket 16. This segmental gear 22 is provided with a laterallyproyect-v ing lever '24 which is intended to bear against the upper edge of the foot portion 12 of the L-sh'aped extension 12 carriel by the tension lever 10 and to be moved upwardly when the said lever moves: in a similar manner and to move downwardly of its own weight.

Suitably mounted upon one end face of the U-shaped. inain stand bracket 16; asbythe screws 25, is a dial 26ihaving the scale lines 27 formed thereon with suitable indicia'as sociated tl'ierewith. An" indicator hand 28 is fastened'--to the end of the pinion stud 19 by means of the screw 2 9'whicjh' is threaded intothe opening; 30 formed] in; the said stud.

The operation of this tension control in dicator may be described asifollowsz- It is to be understood that'the endsjof yarn; the tension of which this indicator intended to register, are passed thru the wire eyelets 9 in the tension? or rock barb. Any increase or decrease intension' upon the strands of yarnwill cause the'tension or rock bar 6 to rotate in the proper direction, the rotatioircausedi by the increase in tension ipon the yarnbeing in a direction for causing upward 'movement of the tension lever 10, while a decrease in tension .upon the yarn en'dswill cause :theitension or rock bar 6 to rotate formovin'g' the tension lever downwardly. It will" now be understood that" any upward movement of" the tension lever 10 will cause the lever 24 of the segmental gear 22 to be moved upwardly for causing rotation of the pinion 21 and pinion stud 19 to produce movement of the indicator hand 28 in a counter-clockwise direction for producing a notification of the increase in tension upon the yarn. Any decrease in tension upon the yarn ends will permitthe tension lever to move downwardly, due to the existence of the weight 14, for permitting the lever 24 of the segmental gear 22 to move downwardly also. This downward movement of the lever 24: will cause the segmental gear 22 to rotate for rotating the pinion 21 and pinion stud 1 9 to move the indicator hand 28 toward the scale line 27 bearing the indic'ia 1.

It will now be apparent that the slightest change in tension on the yarn ends will be."

instantly registered upon the dial 26 by movement of the indicator hand 28 and the operator of the twister, or other similar machine with which this indicator is associated, may take proper steps for reestablishing the tension at the desired degree or restore it to normal.

It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of partsmay be re sorted to without departing from the spirit of the invention or the scope of the subjoinedclaims.

Having thus described the invention, I claim 1.
