Oct. 6, 1931. w. LENK I THREAD BRAKE FOR TWISTING SPINDLES Filed Jan. 5, 1951 invenhr:
Patented Oct. 6, 1931 UNITED fsTATEs PATENT OFFICE 'WILHELM LENK, or nnmsennrn-nmwnr, GERMANY, assrenon 'ro BARMEB MA- sonrmrnnnrx AKTIENGESELLSCHAFT, or REMSCHEID-LENNEP, GERMANY THREAD BRAKE FOR TWIS'IING SPINDLES Application filed January 5, 1931, Serial No.
This invention relates to a thread. brake, which is employed on twistlng spindles, in which during every spindle rotation, two or more twists are imparted to the thread.
Such thread brakes are in themselves known and are arranged always in front of the point of admission of the thread into the hollow spindle in order to thus impart to the thread the tension necessary for the uniform twisting. For this purpose the thread has hitherto been wound several times around a suitable device and then passed through the spindle. This is however open to the objection, that the thread, owing to the difierently occurring tensions, can easily pull tight on the running off bobbin so that thread breakage often occurs. Moreover, the threading of the thread into the hollow spindle at the beginning of the twisting is rendered diflicult, as the thread is not smoothly conducted through the spindle by the running ofl bobbin.
These disadvantages are overcome by the invention. The novelty consists in that the thread brake consists of an outer sleeve, the admission and discharge apertures of which are closed in the interior of 'the sleeve by spring controlled sleeves inserted the'one in the other telescope like. The admission and discharge apertures terminate in the interior as conical enlargements bearing against the sleeves. The sleeves are closed each on the outer end by semispherical heads and pressed apart by a spiral spring arranged in the sleeves. This construction of the thread brake enables the thread to be conducted through smoothly without entangling and to be put under tension merely at its admission and discharge on the upper and lower conical surfaces. The telescoped sleeves can yield in longitudinal or in lateral direction owing tothe conical bearing faces, so that there is no possibility of the thread pulling tight. Moreover, owing to this arrangement, an easy Y "threading of the thread is possible at the beginning of the twisting, as the threading 1 needle can be passed through the tensioning device without hindrance, since the spring controlled sleeves can yield towards all sides. However the sleeves, owing to their conical 506,795, and in Germany January 23, 1930.
trated by way of example in the accompanying drawings in which:
Fig. 1 shows the thread brake in elevation. Fig. 2, is a longitudinal section of the brake.
Fig. 3 is a cross section on line III-III of Fig. 1.
The outer sleeve 1 of the thread brake is arranged for example in the bobbin holder 2 in front of the hollow spindle. The sleeve 1 has an aperture 3 at the top and an aperture 4at the bottom, which apertures have each a conical enlargement 5 and 6 respectively on the inner ends. Telescopable sleeves 7 and and 8 bear against these conical surfaces for the purpose of closing the apertures 3 and 4.
These sleeves 7 and 8 are semispherical at the top and bottom ends and forced apart by an inner spring 9. The thread 10 therefore is put under tension at the admission and discharge apertures 3 and 4, the sleeves 7 and 8, owing to their conicalbearing surfaces 5 and 6 and owing to their construction, being able to yield and shift towards all sides. Evidently the thread brake according to the invention can also be used as spinning and twisting tube.
I claim 7 1. A thread brake, comprising in combination with a twister spindle an outer sleeve having an admission and a discharge aperture, two inner telescopable sleeves in said outer sleeve adapted to close said apertures, and a spring in said telescopable sleeves adapted to force apart said inner telescopable sleeves.
2. A thread brake as specified in claim 1, in which the admission. and discharge apertures are comically widened at the inner end.
to form bearing surfaces for said inner t'elescopable sleeves.
3. A thread brake comprising in combination an outer sleeve having an admission and a discharge aperture conicall enlarged at the inner ends, inner telescopa le sleeves in said outer sleeve, a semispherical head on the outer end of each of said inner sleeves adapted to bear against said conical widened portions ofand to close said apertures in said outer sleeve, and a spiral spring in said inner sleeves adapted to press said heads against the conical portions of said outer sleeve.
In testimony whereof I ailix my signature.
