Application filed December 6, 1916. Serial No. 135,360.

To all whom it may concern:

Be it known that I, MILTON WEIL, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in the Manufacture of Hosiery and other Knit Articles from Raw Silk, of which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and useful improvements in the manufacture of knit hosiery and other knit articles from raw silk whereby the spinnin or throwing of the silk is entirely dispense with and the hosiery produced is of the desired density without an increase in the number of raw silk ends used for each knitting member or strand.

In the manufacture of knit silk hosiery as heretofore practised, it has been customary to spin one or a number of raw silk 1 ends (anywhere from 5 to 25 ends) into a twisted thread (including singles, tram and organzine), to wind the twisted thread onto a spool or the like and then to feed the twisted thread to the thread carrier and to the knitting elements of a knitting machine to form the knitted fabric. It will be noticed that the practice of spinning or twisting the raw silk ends into a twisted thread involves considerable expense but has heretofore been deemed necessary in order to insure thestrength and firmness of the knit article and to allow proper unwinding of the twisted thread from the spool and feeding of the thread practically tensionless to the knitting elements. The feeding of loose, non-twisted ends to the knittin elements of a knitting machine has hereto ore not been carried out, as it was considered impracticable to unwind loose, non-twiste'd ends from a spool and feed the same to the knitting elements without producing entanglement of the loose ends. In a companion application for an attachment for high speed winders, Serial No. 135,359, filed December 6, 1916, I have shown and described a mechanism by which the non-twisted raw silk ends are unwound from the spool and fed in this non-twisted condition and with little tension to a winding'machine or directly to the thread carrier and knitting elements of a knitting machine.

My present invention consists in a method whereby the ends of raw silk are doubled to form what I prefer to term a knitting member having a pluralityof the ends in untwisted relation and then forming the knitting member into knitted interlocking stltches with the raw silk ends remaining in untwisted relation. My invention further consists in a new article of manufacture, namely, knit hosiery or the like, formed of a knitting member which consists of a plurality of ends of raw silk in untwisted relatlon to each other, the knitting member bemg formed into interlocking stitches with the raw silk ends remaining in untwisted relation.

In order to accomplish the desired result 1n detail, I proceed as follows, special reference being had to the accompanying drawmgs, in which- Figure 1 is a side elevation of the apparatus for carrying the method into effect, parts being shown in section;

Fig. 2 is a sectional plan view of the same on the line 2-2 of Fig. 1; and

Fig. 3 is an enlarged side elevation of a portion of the knit fabric.

A number of raw silk ends arranged one alongside the other form a non-twisted knittingmember 10 unwinding from a spool 11 removably mounted on a vertically disposed spindle 12 fixed at its upper end to a suitable overhead support 13 directly above the knitting machine. The bottom flange of the spool 11 rests on a key 14 pivoted at 15 to the spindle and adapted to swing into alinement with the spindle whenever it is desired to remove an empty spool from the spindle 12 and place a filled spool on the spindle 12. It is understood that after the spool is slipped onto the spindle 12 the key 14 is swung into right-angled position relative to the spindle 12 to support the spool 11 on the spindle. The knitting member 10 after unwinding from the spool 11 passes through an eye or similar guide 16 held on the lower end of an elastic band 17 attached at its upper end to an eye 18 of a flexible flier arm 19 terminating in a coil20, the end of which a is fastened to an arm 21 of a hub 22 shown in the form of a heavy coil of wire loosely encircling the spindle 12 and resting on a collar 23 formed on the spindle a short distance above the top of the spool 11. The knitting member 10 after leaving the eyelid passes through a thread guide 25 located centrally below the spindle 12 andabove a winding machine or a knitting machine to be formed into knit interlocked stitches for producing a knit article in which the knitting member 10 is formed of non-twisted raw silk ends. By taking the untwisted knitting member 10 oli' the spool by way of the thread guide 16 held on the elastic band 17 the ends of the knitting member are not liable to become entangled. It is understood that when the knitting member 10 is passed to a winding machine it is wound up on a cone, cop, tube, bobbin or similar spool device, to be subsequently used on the knitting machine for delivering the knitting member to the thread carrier and the knitting elements of the knitting machine, but, as above stated, the knitting member 10 may be directly fed to the thread carrier of a hosiery knitting machine.

From the foregoing it will be seen that by the arrangement described knit hosiery or other knit article is formed of a knitting member of untwisted raw silk ends, which latter remain in untwisted condition on the knit article.

It will be noticed that by manufacturing hosiery in the manner described, the expense of twisting or throwing is entirely dispensed with and the hosiery produced is of a denser quality without increase in the number of the raw silk ends for each knitting member. The strength of the hosiery is not impaired on account of not twisting the raw silk ends.

It will also be noticed that by leaving the raw silk ends untwisted more density is given to the fabric, considering the number of raw silk ends in a twisted thread to be the same as in the untwisted knitting member 10.

Having thus described my invention, I

claim as new and desire to secure by Letters ends in untwisted relation, and then forming the knitting member into knitted interlocking stitches with the raw silk ends remaining in untwisted relation.

2. The herein described method of manufacturing hosiery from raw silk, consisting in doubling a plurality of ends of raw silk in the natural state to form a knitting member, delivering the knitting member to the knitting elements of a knitting machine, and then forming the knitting member into knitted interlocking stitches with the raw silk ends remaining in untwisted relation.

3. As an article of manufacture, raw silk knit hosiery, made wholly of a knitting member which consists of a plurality of ends of raw silk in the natural state and in untwisted relation to each other, the knitting member being formed into interlocking stitches with the raw silk ends remaining in untwisted relation.

1. The herein described method of manufacturing hosiery from raw silk, consisting in arranging a plurality of raw silk ends one alongside the other in untwisted relation to form a single strand, winding the strand on a spool, maintaining the raw silk ends of the strand in untwisted relation while exerting a pull on. the strand to unwind the strand from the spool and while guiding the strand through guiding means capable of flexing and stretching and receding from or approaching the spool, and finally delivering the strand to the knitting elements of a knitting machine to knit the strand into interlocking stitches with the raw silk ends of the strand remaining in untwisted relation.

5. As an article of manufacture, raw silk knit hosiery which consists wholly of a single strand formed of a plurality of raw silk ends in the natural state and in untwisted relation to each other and knitted into interlocking stitches with the raw silk ends of the strand remaining in the natural state and in untwisted relation.
