IMPROVEMENT IN MACHINES FOR WINDING YARN.

Specification forming part of Letters Patent No. 155,161, dated September 22, 1874 3 application filed August 26, 1874.

To all whom it may concern Be it known that I, JOHANN LIEBING, of Asch, Bohemia, Austria, residing in Manchester, Hillsborough county, New Hampshire, have invented certain Improvements in Machines for Winding Yarn, of which the following is a specification:

My invention relates to machines for winding yarn, and consists in a novel construction, combination, and arrangement of parts; and it has for its objects to take the yarn from a spool and wind it into skeins, each of definite length, which skeins are dyed the desired colors and rewound on spools, to be I used by the knitting-machine, and each skein,

when knit into the stocking or other article knit on a circular-knitting machine, forming a separate stripe, as will be fully hereafter described.

Figure l is a perspective view of the machine; Fig. 2, a representation of a stocking knit from the parti-colored yarn.

A represents the framing of the machine; B, a shaft, from which project, at rightangles to each other, the arms 0, on the extremities of which are secured the bars D, parallel with the shaft, thus forming a winding frame, which is revolved by the pulley E. F is a spur-wheel secured to the side of the upright A, and receives motion by the studs or spurs b b on the shaft B entering between its teeth.

is a cam secured on the inner face of the wheel. The wheel F and cam G will be, together, hereafter designated the pattern-wheel. H is a bar, reciprocating in the guides c 0, secured to the upright A A, and is provided, at its extremity near the pattern-wheel, with an anti-friction roller, 01. This bar is kept in contact with the pattern-wheel by a spring, 0, and it will be seen that as the wheel is turned the bar will be operated by the cam G, and have a reciprocating motion imparted to it. f is a cross-bar secured to the uprights A A in the same plane with the bar H. I I are traversing arms pivoted at one extremity to the bar f, and at their middle to the reciprocating bar H, while they are provided, at their free end, with eyes g, through which the yarn is passed. These arms receive an oscillating motion in a horizontal plane as the bar H is reciprocated, the screws by which they are pivoted to this bar working in slots in the arms. h h are the spools of yarn stuck on pins projecting up from the frame A. z i are pins projecting from the bars D to keep the skeins separated.

The operation of the machine will be as follows: The yarn is taken from the spool, and passed through the holes j j in the cross-bar of the frame, situated immediately above the spools; thence to and through the eyes 9 on the extremity of the traversing arms I l, and then up to the winding-frame, to one of the bars of which it is fastened. The machine is now set in motion, and the winding of the yarn onto the frame commenced. At each revolution of the frame 0 D the patternwheel is turned the distance of two teeth; and it having been previously calculated how many threads there shall be to each skein, the wheel and cam are constructed accordingly, so that the same number of revolutions of the shaft B will have turned the wheel so as to bring the cam around to the bar H, and operate it, thus changing the position of the traversing arms, and running the yarn for the next skein to the other side of the pegs or pins z c projecting from the bars D; and thus the operation is carried on, each change of the traverse-arms forming a new skein, until skeins sufficiently large have been wound, when the machine is stopped and they are taken ofi', care being bad to keep them separate. They are then dyed the desired colors, and wound on a spool, from which the stocking-is knit, each skein forming its own stripe in the stocking.

It is evident that the cam on the wheel F may be constructed and arranged to form variously-sized skeins-as, for instance, where a broad stripe between two narrow ones is desired, the wheel would have a long cam between two short ones, the long cam answeringto the broad stripe, the short cams to the narrow stripes, and the spaces between to the white portion of the stocking; or, vice versa,

the cams may represent the white, and the pattern-wheel F G, constructed and operatspaces between them the colored, stripes. in g substantially in the manner described and In practice, there would be pattern-wheels specified.

for each variety of striping.

Having thus fully described my invention,

What I claim is- Witnesses:

The combination, with the winding-frame F. B. KNOWLTON,

O D, traversing arms I I, and bar H, of the OH. F. NALLGIG.
