Be It ltnown that 1. Jan: Smtwrrrntt, n ettiarn of the Swine Confederatitm. and retident of llorgrn. near Zurich, Switzerland, have invented certain new and useful lmrovemettts in 'lhmd-lightening Devices or Rlt'illl audpther Textile )laeltimm, of which the ollowm tea a m-ilieatiou.

In reehng-, trim ingatnl other textile mnehtnea there are used, as a rule. thread-tight: etttng devieea, the object of which is to give to the thread to he reeled or wound on. on the one hand. a uniform tension and to etleet. on the other hand. a uniform teedin or ndmislion, of the name to the reel. lie-e thread tihtetnnsdericea rouaiat. as a rule. of metal grula. cat ting into each other t-rtatawise. mid movided with any desired number of teeth.

ween whirh the thread in guided. tine ot' the grida can moved toward and away from the other and atanda under the action of a weight. There metal teeth however. have the drawback that. althou l they are hardened. ther are eaady attached by the artitlcia and twine. and can t ten not be ttaltd any in r. A further drawharlt of the aaid devioea that the eiae of their brakingattrhoa cannot he lated aa demanded by the dilerent aorta o rt:-

For thi purpoae the teeth are provided with hl'l'tW-ittlit'h t (Fig. Bl. 'l'hese teeth |mssess besides these several projet-tions m. if the thrend to he worked run only tmnl u slight siren-hing. all that is lttt't'rv-ttt') is to remove one or net'- eral teeth and thereby ntljust the tightening derive for the renta-etire thrend.

In Figs. 7 and 8 are shown the teeth used for the nttid sample forms of t-on tritt-tion on an enlarged aenle. from whit-h-ttrerythiug further will at om-e be seen.

Instead of the teeth united with tttt'it other there may also he used single teeth without changing the e-sentinl feature of the invention.
