Fig. 4 is a fragmentary plan view-of a tubular necktie knitted by the apparatus shownin- Figs. 1- and-2 ,"showing: by Way of example,- weltstitches arranged in *cliagonal. pattern on the'rnecktie fabric.

wRef-erring more specifically to the accompany- :ingwdrawing, the circular knitting apparatus to vwhich the :present invention relates may be of a conventional :type, standard in a the .--necktie knitting .trade, consisting of. a stationary needle 3cy-linder 40; on which are mounted, in the-conventional way, knittingneedles i I having latches at "their uppenends; and butts l 3" adjacent .their :loweraends. 1A rotary, annulantable lfiis::ar-

ranged about the cylinder .1 0.

:Mounted on table I 5, :in the conventional :way, are two pattern wheels l6" and ll, respectively,

disposed irr-diametrically..opposedtposition. Associated with each. pattern-wheel are liftingicam elements: 18. and i9, respectively, and istitchmam elements 2B and 2|, respectively. 'The cam surfaces .of :the lifting and stitch" cam elements are spaced apart, to form the needle butt track or guideway 22.

In the conventional apparatus, as heretofore used, there were provided on the table I5, rectangular, radially disposed recesses 23 and 24, respectively, adjacent each of the pattern wheel positions 16 and I1, respectively, and to the rear of such wheels. The recesses 23 and 24 open into the needle butt track 22, and receive therein cam blocks, such as the cam block 25, having the cam surface end 26 extending into the track 22, and adapted to receive thereon needles selectively positioned by the adjacent pattern wheel to engage upon the cam surface thereof, and be placed in knitting position; the other needles not so selectively positioned being disposed in tucking position.

It will be apparent from the foregoing description that the apparatus to which the present invention relates, as heretofore constituted, could knit only knit and tuck stitches, with a consequent limitation on the patterns and designs that could be produced upon them.

In order to enable the increase in the variety of stitches that could be knit on such apparatus, with a consequent increase in the variety in the patterns and designs of the tubular knitted neckties that could be produced thereon, I have devised means which may engage the needle butts l3 toadjust the needles I l, or a selected number of them, to welting position, thereby enabling the knitting of knit, welt and tuck stitches, or knit and welt stitches, as desired, upon the apparatus.

Such welting means comprises a cam, generally designated as 33, comprising a rectangular body portion or block 3|, adapted to fit in the recesses 23 and 24, and to replace therein, in either or both of them, the cam block 25, which is conventionally arranged therein. The cam block 3| may be secured within the respective recess by the same means as the cam block 25, orby any other suitable means, many of which will suggest themselves to anyone skilled in the art,

The block 31 may have mounted on its inwardly facing end 32 a diagonally disposed cam blade 33, arranged at approximately right angles to the tilted adjacent pattern wheel, such as the pattern wheel [6, as shown in the illustrating drawing. The upper end of the blade, which is closest to the pattern wheel, has a forwardly extending, substantially horizontally disposed needle separating lip 34.

It will be readily apparent that a selected number of the jacks on the pattern wheel I6 may be set to raise the butts l3 of a selected number of needles I I, to be engaged on the upper face of the needle separating lip 34 of cam blade 33, so that such selected needles will be normally engaged by the stitch cam element 26; while another selected number of jacks may be set relatively lower, to raise another selected number of needle butts only sufficiently high to be engaged against the lower face of the needle separatinglip 34 of the cam blade 33, so that the respective needles will be depressed'by the cam blade 33 below the knitting or tucking position, to a welting position.

It will be readily apparent that if only one cam 30 is used on the apparatus, replacing one of the cams 25, a necktie having all three types of stitches in its pattern and design, namely, knit, tuck and welt, will be produced; while if both of the cams are replaced by a cam' the knitted necktie will comprise only knit and welt stitches.

In order to avoid the possibility of damage to the needles by the cam blade 33, which is positioned athwart their passage, the blade 33 may be resiliently mounted to be rearwardly displaceable, so that any needle butt strikin the edge instead of a surface of the blade will push it rearwardly, out of the way, rather than be damaged thereby.

One form of such blade mounting is shown in the embodiment illustrated in the drawings, wherein the forward end of the cam block 3| is diagonally slotted to receive and guide the blade 33, and to permit its longitudinal movement therewithin. A longitudinal passageway 36 is formed in the cam block 3|, extending from end to end, with the outlet 31 therefor, at the rear end of the block 3| bein of reduced diameter, to form the interior shoulder 38. To accommodate the rearward movement of the blade 33, the forward upper corner of the block 3| may be entirely cut away, so as not to block the lip 34.

A plunger 39, having the relatively thicker head portion 40, adapted to fit snugly within the passageway 36, is arranged within the passageway 36, its opposed end passing through and projecting from the restricted outlet 31. The blade 33 is mounted on the head portion 45 of the plunger 39, and a coil sprin 4! is arranged over the plunger 39, intermediate the shoulder 38 and the head 40, to urge the blade 33 resiliently toward the cylinder H]. In order to retain the blade within the track 22, flush with the edges thereof, so that it will not interfere with the movement of the table [5 about the cylinder l6, an adjusting nut 43 is fitted over the threaded projecting end of the plunger 39.

A recess 44 may be formed in the wall of the guideway 22 to permit the rearward movement of the blade 33 when necessary.

It will be readily apparent that if any of the needle butts I3 strike the edge of the blade 33, instead of engaging the surfaces thereof, the blade 33 will be pushed out of .the way, without damage to the needle, and will return to position upon passage of th needle.

This completes the description of one preferred embodiment of the apparatus and product of the present invention. It will be readily apparent that many modifications and variations thereof may be made by any one skilled in the art, in accordance with the principles of the invention hereinabove set forth and Without the use of any inventive ingenuity. I, therefore, desire to be protected for all such variations and modifications that may be made within the spirit of the invention and the scope of the claims hereto appended.
