H of illinois, haveinvented certain new and useful Improvements in Knitting-Machines,

. of which the 'following-is;` a specification.

The object ol'this invention is to provide means, in a knittingmachine,v for holding f. the yarn at the point of transfer of yarns, or

between the ending of one stocking and the commencement of another.

The further object of this invention is to automatically triin'the stockings in the procereby saving the expense of trimrnin 1' by hand, also the liability `ot and by trimming the stockings automaticelly a great saving of yarn and in labor is made. ln the accompanying drawings, Figure 1 is a plan vieiv of a portion of a straight knitting machine containing my improvements.

VThe machine in `which my present im proveniente are embodied generally diecloeed in Fig. 14, and iso'f the saine general type as that machine found in my Fatent No. 616,600. It willbe unnecessary to 4describe in detaihthe` general` structureA of the inachinefas my present iniproveniente4 relate rather to detailed improvements than to general structure, and V1t is sullicient to point out that the. machine comprises the 'traine parte y15 conneotedby the crof-:epieces 1t` and having the jack-Slides 17 ior operating the needles, yarn-holding devices and yarn-severing devices. The usual yarn carrier 'l having latch-openers is mounted inA suitable Ways above the needles, any usual means lor moving `the yarn-carrier being, provided., as yarn-carrier slides 19, which `are connected by the cross-bar 20. The same type of carrier-wheel 21, tor the yarn-slides or ,(iirriersis provided as in iny foi-momenten@ referred to, Aandytl'gie yarn carrier; slides are provided with a] suitable cross-plate or platee referred to.

` The needle vision plates 1, the 'needle Supporti-i2,` 3 are located vbetween the divisionplatee 1 and each isprovided with two feet 4 and `he pattern Wheels 6 are located with rela' tion to the feet'of the oscillatory leversl, that the feet may be actuated thereby. Needle jacks 7 are moved bythe.. oscillatory levereinto andout of engagement with the earns 8. The means orreciprocating the carne are not shown, as it ie well linden stood. i l

At Figs. l and 5 is shown a knitting needle support with a linittii'lgneedle l5 in place.

At Figs'. 6, 7 and 8 is shown a yarn holding needle support which has the eideplates S ol greater height than the side lates of the knitting needle supports, V,an

of the di..

beds arel made up are located between v which outward under 'pressure like the needle supports, with. Awhich is Shown 'a needle sha-nk.

At Fig. Q is shown a holding needle ers.

.9.2, all as in the patent The oscillatny-levertl ;cover the hooked end l() of. theJ holding needle 11. Ae shown at Figs. Pand lloneof the eide plates .:l ie Separated, a part of ite height from .the needle support in order that it may yield tended and a knife withdrawn. At Fig. 3

the knife is shown extended and the holding needle Withdrawn. The holding needles and knife or knives arc operated by the knitting cams and their time of movement controlled by theA pattern ivheel iii the same manner as the knitting needles in the machine.

lrawn down between the side plates 9 of the needle support and will be clamped between the needle and side lates. Owing to the varying thicknesses ov yarn, and to the different thicknesses of yarn that may be einployed, one of the side plates is made latorally yielding. After the yarn has been seized by one of the holding needles, the return movement of the needle cam will extend the knife and sever the yarn between the ho/lding needle and the fabric, and the continued return movement of the needle cam will Withdraw the knife. The knife may be operated a number of times to insure the yarn being severed. This operation is repeated at each change of yarn or at the finish of each article. At Fig. 13 the knife is shown with a hooked sharpened end 14, and a knife of this construction Will sever the yarn held by the two. yarn holding needles. n

In the claims I have stated that the needle beds or needle supports are formed with grooves within which are located the knitting needles, yarn holding 1 needles and,` knives. I Wish it understood that'the grooves may be formed by the beds bein biillt up as shown by my patent above referred to, or can be formed in the materialfdf `which the beds or supports are made. l

l. claim as my invention:

l. In a knitting machine the combination of a needle bed, knitting needles supported by the bed, yarn holding means .located adjacent to one end of the needle bed, to hold the yarn in position for cutting, and a yarn severing knife located adjacent to one end of the needle bed, the yarn holding means and knife being movable transversely of thefneedle bed. v
