Fi 1 is a pan view of 'arn furnishing whee s and a portion of the ead supporting Fig. 2 is a front view of the yarn furnishin wheels andthe associated devices. y 'ig. 3 is a side view partly in section.

Fig. 4 is a sectional view of the supple- "V16 mental yarn furnishing wheels.

Fi 5 is a view of the furnishing wheels detac ed.

The yarn from the bobbins, not shown, passes between furnishing Wheels 5,6, 57, 58, 20 one setfor each feed, and thence to the yarn uide at this feed, and provision `is made for delivering two yarns to each feed, one of which is a plating yarn. s

'On their 4way from the furmshing wheels 88 to the yarn guide the yarns ide ends of dropper ngers 1 and 17 and ied guides 18 'adjacent thereto. These dropper fingers control stop motion means. The broad wheel 56 and the two narrow wheels 57 and 58 have long teeth intermeshing so as to measure ofi' the yarn passing between them in suitable and accurate lengths or sections to properly supply the needles to which the yarn is led without being subjected t'o .any variable tension, there being no tension devices employed between the furnishing wheels and the needles.

The toothed wheel 56 is mounted on a shaft 59 bearin in the casing of the stop motion head an this shaft has a bevel gear 60 on its inner end meshing with a suit-able bevell'gear which is driven in unison with the needle Icylinder in any suitable manner.

each feed passes between the furnishing wheels 56 and 57 and the other yarn passes between said w-hel 56 and the wheel 58. These'wheels 57 and 58l are carried by a swinging bracket consisting of the depend-` ing arm 62 and the substantially horizontal arm 68, the bracket being pivotally mounted at 64 to an ear or post 65 on the. vframe of the stop motionhead.' The bracket is adjustable by means of a nut 66 bearing on `its pass through forked end 67, said nut being on the screw threaded lpost or pin 68 mounted in the frame of t e stop motion head. A jam nut 69 holds the parts in adjusted position. A.

spring 70 maintains the bracket `up againstv f, 00

e nut 66, but the bracket may yield to allow for variations in the yarn, or for the passage 'of lumps. which, however, will be taken careof by any suitable detector means at the needles. The -adjustmentof the bracket will vary the depth of mesh of the teeth and thus lvary thelengths lof yarn furnished the needles in exact accord with the demands of the needles, which, of course may be made to draw longer or shorter loops. Besides the adjustment of both wheels 57 and 58 relative to the wheel 56, it is to benoted that the wheel 57 is adjustable relative to wheel 56 independently of wheel 58, so that lthe furnishing of one yarn may be regulated in degree in respect to the amount of yarn furnished by the other wheel in order to get the proper relation during plating.

For this purpose the wheel 58 is mounted on a in 7l carried by the swinging bracket and t e other wheel is mounted on an eccentric sleeve 72 turnable ona reduced part of L the pin 71 and held by a nut 73 screw threaded upon the pin. can be turned by the finger piece 74 and when so turned it will cause the wheel 57 to .mesh more or less deeply with the wheel 56.

lshown at c and with reduced tooth portions d which perform the function of measuring off or furnishing the yarn but do not act as One of the yarns of each pair a, a at\ driving means.

' This structure will prevent the yarn from The eccentric sleeve l tain irregularities in the action of the yarn and prevent these fromaffecting the stop motion mechanism, which therefore will not have to be set to take care of these.

I claim:

l. In combination, a pair of yarn furnisby ing Wheels having intermeshing teeth Witn, portions for driving one from the other,

and having other toothed portions of less thickness than the driving portions, Which v .other portionsperform the function of yarn furnishing Without performing the unction of driving one Wheel from the other, substantially as described. i i
