; The object ofthe intention is" op'royide improvements in knitting mach esg an' dpan ticularlyin an attachment which is applicate toreyolving cylinder, (circular) or reyolving' cam- (stationary cylinderyf niachines pon.

; Referring tovthe means for carryingrout the object thus broadly stated,.a' rotary yarn guide 1s mounted upon arevolvmg support above the plane of the needles, together witha' relatively stationary rack or other suitably formed element, whereby said guide, which is normally fixed with respectto said support, upon encounteringgsaid element is itself rotated independently oi' its support, with the result that for a'relativ ely brief portion of its circular path it describes a planetary motion, and in so doing carries the yarn i around the upper-portions of as many needles as may be desired, and again remains fixed until it again encounters said element,

With theforegoing facts in mind, the {ins 'vention comprises further details of construction and operation such as areclearly brought out in the following description, when read in conjunction with the accompanyingdrawings in which Fig, 1 is'a side elevation of one embodiment of the invention, showing" the rack element in verticalsection; land Fig. 2 is ahorizontal-section on the line of Fig. l.

VVhe'n the attachment is applied to a re volving cam machine, the rack with teeth I 21 revolves with the cam or cams, and the v cylinder 10, disc 9, yarn rack 2, etc., remain s a ya a There may be'employed asmany of these improved yarn feed devices as may be desired, or as may be practicable, depending upon the type and design of machine which may be involved. The disc 9 with its sup- Egrting drive shaft 1 and yarn rack 2 may rotated'by any suitable mechanism which ,may comprise either the same or different means thanthat which rotates the cylinder 10. Also, the respective guide tubes 13, and l4-may bewithdrawn and replaced when-o ever necessary or desirable, forrepair or substitution by simply lifting them upwardly and free from the bores 12 in the supporting disc 9, after firstlooseningthe nuts or screws by which they are operatively secured in position.

In the operation of the invention, the

knitting machine is operated in the usual manner, but the yarn 6 passes to the needles the yarn from its depending free end needles which'may be in raised position at a predetermined point in the circular needle row, or in the path of the arc of needles as the latter, are being raised and lowered out of their normal, position of rest. 'Through each of-these rotatable yarn feeds can be passed adifferent type of yarn or silk thread, or as manydifi'erent colors as may be desired,

either singly or in multiple, so that as many a; stripes or other ossible designs are produced in the finished tary feeds. a V 7 Having thus described my invention, what I claim and desire to protect by Letters Patit product as there are roent of the United States is 7 1L Thecombination of a knitting'machine comprisinga cylinder of needles and a support rotatablemin synchronism therewith, with a yarn guide rotatably carried by said sup ort upon an'axis eccentric to the axis of sal support andcomprising a toothed head having aicentralbore and atube communieating with said bore and having its free end terminating laterally of itsaxisof rotation with respect tosaid support and below the level of theupper ends of said needles'when they are in raised position, a relatively stationarytoothed rack adapted to engage and ro'tate'the toothed head of said guide with respect tosaid supportv and to said needles while in a predetermined portion of its path or orbit, to cause yarn from the free end of said guide tube to encircle a predetermined set of needles, and resilient frictionally braking means engaging and limiting the rotation of said head with respect to said support to only the movement imparted thereto by said rack.

I 2. The combination of a knitting machine comprising-a cylinder of needles and a support rotatable in synchronism therewith, with a yarn guide rotatably carried by said support upon an axis eccentric to the axis of sa1d support and comprising a head having a central bore and a tube communicating with saidbore and having its free end terminating laterally of its axis of rotation with respecttos'aid support, means to rotate said head of said guide with respect to saidsupport and to said needles while in a predetermined portion of its path or orbit, to cause yarn from the free end of said guide tubeto encircle a predetermined: set of needles, and resiliently frictionally braking means engag, ing, and limiting the rotation of said head withrespect to said support to only'theomovement imparted thereto by said first means.

In testimony whereof I have afiixed my signature.
