IMPROVEMENT lIll KNTTING-MAGHINES.

TO ALL WHOM 'IT MAY GONCERN:

Be it known that I, SAMEL LARKIN, of Bridgeport, in the county of Faireld, and State of Connecticut, have invented a new Improvement in Knitting-Machines; and I dov hereby declare the following, when taken I in connection with the accompanying drawings, and the letters of reference marked thereon, to lbea full, clear,

andcxact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure l, a side view. l

4Fignres 2, 3, and 4, detached parts to illustrate my improvement; and in Figure 5, the work which the machine is desired to produce.

This invention relates to an improvement in theknitting-machine inventedby'd. and A. House, and

` for which Letters Patent ci the United States were granted, bearing date March 13, 1866, of which said invention the assignees of this present invention arc also the assignees.

The object of this invention is to knit in stripes with two coloris, thatY is, to make alternate stitches with diiercntcolored threads. i

-In Vthe original machine, when twothreads are used, a stitch is noeessarilyformed fromv each thread upon each needle, which, if two threads are used, linits in stripes across the work andV not in vertical stripes. This invention, therefore, to accomplish the desired object, consists in combining with the hooks and needles a lever or linger, which holds the thread away from andfso as te pass alternato needles, so that the same color is brought continually to the same needle, and thus vertical stripes Aare knit.` i

To enable others to construct and' use this improvement, I will'proceed to describe the same as illustrated in the accompanying drawings.

A is the bed-plate, a the needles, arranged .in a continuous chain, and operated in like manner as in the original patent or" House.

B is the knitting-hook, arranged upon the arm C, and upon which said arm the presser-finger D is also i arranged, the hook forming the stitches and the nger D pressing them down, all in like manner as in the original patent of House, receiving the thread through the guides E.'

Each operation et' the hook forms a stitch, with two threads and 'two hooks, as denoted in g. 2, and as described in the original patent, two stitches beingormed at the same time, i .When knitting with two threads of the same color,'the stitches are formed continually one above the other, each successive line of stitches around the work being formed from alternate threads. u

If colored threads are used, it w-ill be seen that' the threads will necessarily lie so as to form a simple,

plain ring around the Work, but in sing threads of two colors, it is desirable, at many times, thatit be wrought in stripes, as seen in iig. 5. On the original machines this wasimpossible, but by my improvement I am enabled so to do, and this is accomplished by, at each movement of theneedles, holding the threads hack, so that they do not pass under the hook o'f' the next needle, but skip over to the second, that is, the threads respectivelyA taking alternate needles.

To accomplislrthis, I arrange a-lever orfringe, d, which, hung atf on the carrieris operated by a cam, b, so that, as the presser-finger goes down, and ixmnediately before thcchain of needles moves, the finger-0l is thrown forward from theposition in iin. 1 to that in figs. 2 and 4, so as to carry the thread back of the needles,

the redvline denoting the thread thus held' back, whereas, without, the finger rl, the thread would be carried nnd'cr the hook, as denoted by the broken line, g. 2. So soon as the needles have moved one point, and the carrier rises, the ngcr cZ falls back, as denoted'in iig.' 1, and the threads are brought up under the second hook, as denoted by the rod line, fig. 1, and thus each stitch of like coloris formed upon alternate hooks, each color skipping the needle -upon which the other formsa stitch, se that continuallyithcsame color falls under the hook of the same needle at each revolution of the chain.

Saeco 2 If more than two colors are used, the finger operates in the same way, the needles being carredalong so as always to bring the same color upon the same needle. l

If, after knitting a short distance in this inanner, it be desirable to alternateeso that a short stripe of one color shall be made above a short stripe of another oolor, and thus form cheeks, as it were, it is only necessary to adjust the chain of needles one point, and the eolors will be reversed upon their needles. Thus, by the simple application of the 'finger d, I am enabled to produce upon this machine a great variety of work.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

The inger d, constructed und operated as described, seas t6 carry the threads over any given number of needles to form the stitches in the relative position to eaeh other, substantially as set forth.

SAMUEL LARKIN.
