To/1,7 7 wil/07m it may concern: e Be it known that I, (lurrom) B. POTTER, a citizen of the United States of America,

llampden and State of Massachusetts, have invented new and useful Improvements in Yarns and Processes of Making the Same,,-of which the 'lOllOWHIg is a specification.

This invention relates to the textile art,

and it has special, reference to yarns and to the process or making the same:

The object of the invention is'to provide an improved yarn composed of fibers whose normal lengths are unequal, as of cotton and.

wool fibers, and te rovide an improved y the 7 mixed fibers may be worked on ordinary octchine and drawn into a sliver, as shown in Fig.

ten working machinery regardless of the proportionate quantity of wool fiber in the mixture.

it is well known that in order to work a mixture of cotton and wool fibers on a machine adapted to cotton if the proportion of wool exceeds a certain amount it is impossible to produce agood am. This is largely owing to the fact that t e wool fibers are very much longer than the cotton fibers. it is also known that in mixing fibers of cotton and wool it is exceedin ly diflicult to produce a yarn through WlliCl the wool is evenl distributed, and it is also difiicult to pro uce a yarn from such mixture of uniform thickness. These dilliculties have in a measure been overcome by using some short-fibered wool, such as noils, with the cotton; but the supply of this material is totally inadequate to the demands of the market.

In the drawings forming part of this appli-.

cation, Figure 1 represents a bunch of cotton fibers, and Fi 2 represents a bunch of woolen fibers; T ig. 3, a portion of a sliver of wool, and Fig. 4. shows two subdivisions of the sliver. p

in carrying this invention into practice the length of the cotton fibers which. are to constitute a part of the mixture is first ascertained, and it may be assumed that these are represented in Fig. 1 of the drawings. The wool which is to constitute the other portionef the mixture is then run through a suitablema- 3, and this is in turn put through a machine which will cut it u equal to the lengtfi ofthe cotton fibers whic constitute the other portion'of the mixture into lengths substantiall a between'theidotted lines I) b. The normal length of the wool fibers as compared with By thus treating the wool the average length of itsfibers cannot exceed thej'average length of'the cotton fibers, and the two may be worked together by means of machinery these lengths beiiig indicated by the portions 'cotton'may be assumed to be shown in Fig. 2.-

adapted to operate on the normally shorter fiberr It has been found in practice that by thus unifying the length of the fibers a uniform distribution of the wool throu h the cotton',--or vice versa, in the process 0 manufacture can be relied upon. Furthermore, the uniform length 0f the fibers results in the production of a yarn possessing reat uniformity, whereas when any mixture of two fibers Whose lengths are as unequal as those of cotton and wool is made the am will be drawn out thin in spots and wil remain bunched. iri other s ots.

A still further advantage is possessed by a yarn made under the process herein disclosed, and that advantage consistsin the fact that the proportion. of wool to cotton may be materially reduced Without resulting deterioration in the apparent qluality of the fabric made from the yarn. he reason for this is that the soft or woolly feelin which the addition of the wool gives to t e fabric or the yarn is due to the projection of the ends of the fibers beyond the surface of the fabric or yarn, and it therefore stands to reason that with an admixture-0f wool fiberswhich have been out into lengths substantially equal to the cotton there will be provided in a given length ofyarn a larger number of ends of the wool fibers which may project beyond the surface to produce this soft feel in the goods. Another advantage and a very great one resulting from this method consists in the fact that it is immaterial what the proportionate quantities of wool and cotton may be in the mixture if the average len the of the two fibers be e ual, for the mass wi 1 work equally well What er the quantity of wool be thirty per cent. of the whole or seventy-five er cent. of the Whole, Whereas when wool fi er is used which is long as compared with the cotton and the quantity of wool is as.much as fifty per cent. great difficulty ,is experienced in workin such a mixture, and it is practically impossi le to work it on machinery ada ted may be manufactured by a mill fitted With machinery adaptedonly to cotton is greatly increased by means of this process.

In carrying out the present invention it is to be understood that it is obviously neces sary that the WOOl fibers be arranged in parallel order prior to the clitting thereof and scribed. As to the use of the Word Wool herein, this term is to be considered as including all the animal fibers of like nature to Wo0lthat is, inclusive of all the fleece fibers. Having thus described my invention, What I claim, and desire to secure by Letters Patent of the United States, is

1. The method of making a cotton and Wool yarn which consists in drawing the wool into a sliver, then mechanically subdividing the latter transversely into sections Whose length shall equal substantially the length of a the cotton fiber, then mixin the fibers and forming the yarn in the usua manner.

2. A yarn composed of cotton and Wool fibers, the latter being cut from a sliver into lengths correspondin substantially to the length of the cotton ber.

. 3. A yarn composed ofcotton and WOOl fibers, the latter being cut from a sliver into lengths correspondin substantially to the length of the cotton fi ers and uniformly distributed therewith throughout the yarn, said wool fibers presenting an extended area of CLIFFORD B. POTTER. Witnesses;
