SPECIFICATION forming part of Letters Patent No. 498,139, dated May 23, 1 93.

Application filed m 22, 1392.

To aZZ whom it may concern:

Be it known that I, GEORGE E; NYE, of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Circular-Knitting Machines, of which the following is a specification.

My invention relates to: that class of circular knitting machines in which vertically reciprocating latched needles mounted in a revolving cylinder and actuated by cams, cooperate with a series of horizontal latched needles mounted radially in a dial plate and reciprocated by cams.

It consists in improvements designed more particularly for use in connection with the machine patented to me on the 28th day of April, 1885, No. 316,907, the principal object being to produce tuck stitches by any desired number of the dial needles and plain stitches by the remainder, and thus to produce ornamental fabrics such as could not be produced on the original machine. This result I secure by making use of dial needles of two or more forms, diifering as to the location of their shanks or studs, in combination with separate operating cams for the needles of the respective forms, and a thread guide which delivers the one thread to all the needles in the series without regard to their forms or movement. By this arrangement, underwhich the dial needles of one form are operated independently of the others, I am enabled to impart different movements to theneedles of different forms, and at the same time having them all act on the one thread so'as to produce the required changes in the stitches during the knitting of each round or course auto matically, and without changing the fabric from one set of needles to another.

While I commonly use my improvement in connection with the dial needles it may be applied in the same manner and with like effeet to theoylinder needles.

Inthe accompanying drawings,Figure 1 represents in side elevation a machine en1- bodying my improvements, a portion-of the cylinder, dial and cam mechanism being shown in vertical section. Fig. 2 is a bottom plan view of the cam mechanism for operating the dial needles. views illustrating the dial needles in their two forms.

Figs. 3 and 4 are side $erial No. 440.915. ca may Fig. 5 is a sectional elevation illustrating the manner of constructing and operating the lifting cam of the cylinder needles. r

In the drawings I have represented my improvement applied to a machine which is in most respects identical with that shown in my patent above referred to.

A, represents the tubular rotary cylinder provided with grooves to receive the vertical needles a, which are raised and lowered by r stationary cams P P engaging their heels.

B, represents a rotary horizontal plate, usually known as the dial provided in its upper face with radial grooves containing the horizontal needles 121), which are reciprocated by cams on the under face of the stationary plate 0, in essentially the same manner as in other machines known in the art. I

In carrying my present invention into effect I provide dial'needles of different forms, such as shown at b and 1), Figs. 3 and 4, having their heels or studs 12 on which the cam operates, at different points in their length. As these needles difiering in form cannot be practically operated by the same camsIprovide special or separate cams for each form of needles. As shown in the drawings the needles 6, are of they usual form with theheels s near their inner ends. They are actuated by the throwout cams c, and the drawing-in cams E and F, as shown in Figs. 1 and 2, these parts being as regards their external form and their actions on the needles substantially identical 3 in their construction and modeof action with those represented by the same letters in the patent No. 316,907. The needles 1), however, instead of being actuated by the above-mentioned cams are moved by the engagement of 0 their heels with the drawing-in cams G, which I now apply to the machine for thefirst time, and with the outer edges E F of the cams E and F, which are now formed on their outer edges for the first time to serve as throwingout cams. By means of the extra cam surfaces the needles b, are operated independently of the needles b.

By forming the draw-in cams as shown, and making them independently adjustable they I00 may be so set that the needles actuated thereby will only reach the full limit of their institches, but will not be drawn in lfar enough; by the left hand cam to cast oif. The needles I) will thus receive two stitches before casted with, and operated by, the same slide H; or they may be operated by. different slides and pattern chains; or one of said cams may be movable and the other stationary. It will be observed that in Fig. l of the drawings two plates H, areshown though only the lower .one islsho wnl connectedlto an actuating link. By giving *the pattermchains which operate the respective cams suitable forms, the neeing OE, and will cast off onlyoncerrinreachf -*dleshqnayvbecaused to knit the plain and round, producing the familiar tuck stitch.

By a proper construction of the pattern chains by which thercamsfare moved'any: group or;

series of the needles 1) may be caused to knit either plain or tuck stitches, in anyronnd or course.

I deliver the thread to' the needles by the "usual fixed guide 7a, which 1 lays one and the same thread within the'grasp 0f 1 all the nee- 2o dles. It is to be noted that in my machine the one thread is delivered i throughout the entire course 'orroun'd to all the needles'and, that although the different-dial needles move different distances a; and i produce di iferent 25 forms of stitch they act 011- the one thread.

The cams c and 1 G may be fixed per-manentlyin position, in-whieh'case the' machine will imit a constant pattern; the figure of which w ill depend on" the' manner in: which the needles b 'b'are grouped or arranged in it relation to" each other,- but I prefer tomount them on pivots that they may be sw ung= in. ward and outward, and :to "connect them.

the tuck stitch alternately at such intervals as the chain may determine, and in like manner the needles b, may be caused to knit the two forms of stitch alternately by means of thispatternchain. The essence of my invention resides in the combination or d'ial needles di'ffiering in form from each lother; tandzxarrangedr in one row or iseriesy with cams rtot operate themi independ- -"ently,' and witlr a thread 'gmide whichlaysione aud thelsame thread? to an the-isaid needles, and any'ireq uivalent construction rwh-ieln en- "ables th e'iactuating "cams to distinguish between' the 'di lierent groups of fdiah needles is "any invention.

ltrwill be observed that :und'errmy construction the needles of ther twohficnms may be grouped or arranged in any desired order of successionyand that arry desiredmnim ber of them may ef one farmland. the remainder of J. the otherformr according methe design of thellfabric to' be produced.

or they may be connected with different actuating devices to be moved and set independ' ently of eachothen'and in diiferentpositions, to produce stitches of diiferent pattern; as may be desired. 1 One of the newcams, G, is connected at its freeend to aslideHpconnectd byailink 'I, to an elbow-lever J ,whichis actuated bya 6o pattern chain,- the construction and "operation of this pattern chain and leverbeing'es- *sential-ly thesame as those above described.

The two cams G, like the camsc, may be connect- While the drawings show only one of -the? present invention, and that they:hnay be' re- 1 placed-byanyequivalent pattennrmebhalnism of 1 which there-is 'at the present timetahn umber familiarto every persen skilled in thisart. represents the l usual roam located in the 1 frame outside of -thecylinden to actnate the -vertical cyltnder needles.

2. In combination with the needles differing in the form of their shank, the cam F and the cams c and G, and means for independently adjusting the cams c and G.

In testimony whereof I hereunto set my hand, this 26th day'of March, 1892, in the presence of -two attesting witnesses.
