SPOOLER BOBBIN HOLEER.

p Application filed September 3, 1926. Serial No. 133,488.

varies from thefull quantity atthel loe-V ginn-ing of the winding operation to nothing when the operation is concluded. The mass of yarn also varies with the size of the bobbin. It is desirable also to have the yarn i mass on tliepbobbin as large as can be advantageously handled ou` the spoolcr. It will be seen, therefore, that the tension on the' yarn drawn off from. the bobbin will vary greatly yunder these varying conditions. This varying condition is' further accentuated by the vibration orjumping of the bobbin during the winding operation.

The object of the present invention is to provide a simple and efficient means for controlling the tension on the yarn as it is unwound from the bobbin.

The object of the invention is further to provide'means presenting a yield or give in the rest upon which the bobbin is supported so as to ease the shock when 'the bobbin `iumps or vibrates and thus reduce the strain on the yarn. y y

The object of the invention is further to provide a simple construction which may readily be applied to existing bobbin holders for securing the desired results.

These and other objects and features of the invention will appear more fully in the accompanying description and drawings and will be particularly pointed out in they claims.

As the invention relates entirely to the means for supporting the bobbin during the spooling or winding operation and as 'the general construction and operation of the spooler or winding machine are well known and familiar to those skilled in the art, it is only necessary to illustrate and describe that portion of the machine with which the present invention, in a preferred form, is directly concerned.

In the drawings:

Fig-1 isa side elevation of a bobbin iholderf of an ordinary typewith a preferred form l of `the. present invention embodied vtherein with the ordinary 'supporting `bar of the spooler frame shown in cross section..

Fig. 2 is a front end elevation `ofthe conf.

structionishown. in Fig. l. r F 1g.` 3 is ade'tall 1n perspective rest employed in this invention.

The ordinary spooler frame is `provided with bars such as l extending longitudinally of thev frame at each side. On*` these bars' are mounted, extending horizontally and slightly upwardly away from` theframe, a.

series of bobbin 'holders each :supporting Ia bobbin from which the yarn isxdrawn, in-

the spool-ing opei'ation, to the spools abo-ve on they fran'ie. The bobbin yholders are all alike so that it is only necessary :to illustratey and describeifone of them.

The ordinary bobbin holder .comprisesa of a lbobbin y bracket 2 forked at its lower end to embracethe ,barr l andlocked thereto, as `by `the set? screw 3. Tliisbracket caririessecured there-r to or integral therewitlnga support kor p'an l having a concave central section 5 and side flanges G. The upper surface o-f this pan inclines upwardly, 'and upoii this surface the bobbin. iisuallv'rests with the yarn mass in. vcontactl with the concave section.

From the bracket 2 ext-ends upwardly, and overhanging the pan, an arm 7 in which is pivotally mounted a pair of wire'guards 8.

These guards swing by gravity against op# posite sides of the yarn mass 9 on the bobbin 10 and thus maintain the bobbin in.

10ovv In the present invention there/is provided I a plurality of concave yielding vrests preferably made of strips of sheet spring metal. A preferred form of one of such rests is shown in Fig. 3. The central portion llis concave and on a flat-ter arc than the concavity ofthe section 5 of the pan. The ends of the rest are bent as indicated at 12 loosely to Fig. l.

Thus the weight of the bobbin is taken off' from the. extended surface of the pan or supportl and transferred to the surfaces of these rests.

Not only, therefore, is the width al d character of the supporting surfaces for the bobbin under control but also the spring or yield in the rests lthemselves is found to be a highly desirable factor in preventing breakage of yarn due to the vibration or jumping of the bobbin when the mass of yarn-is relatively large and heavy. It is found that by tne use of these rests, the speed atl which the spooler is operated may be substantially ncreased. It has thus been found possible to increase the speed about 40%. more, ,owing to the fact that the breakage of the yarn is very substantially reduced, the labor required in piecing the ends Aand maintaining the spooler in operation 1s muterially reduced. It is found that one operator can'handle three times as many'spin;`

' dles as heretofore.

' It will also be seen that the invention, as

v in the preferred form illustrated, may readilyT be applied without alteration to existing spooler frames which is of great advantage.

Furtherh The present invention, therefore, enables the yarn to be wound tightly and in a large mass on the bobbin in the spinning room and the spooler to be run at high speed because of the control of the tension provided by this invention, and all this'is done by a simple construction readily applied to exisiino' spooler frames.

-Iaving thus described the invention, what is claimed as new, and desired rto be secured by Letters Patent, is: n

l. A bobbin-holder for spooler fra-mes comprising a support presenting a plurality of concave yielding rests extending transversely of and longitudinally spaced along` the support to hold the bobbin during' the spooling operation.

:2. A bobbin-holder for spoolers havingthe construction defined in claim l in which thev ing the construction defined in claim l. inv

which each rest is a narrow strip of sheet spring metal having hooked ends loosely embracing the side edges of the support.

In testimony whereof, I havesigned my name to this specification.
