cylinder revolves, the butts come in contact with and slide up and down the inclines or cams, and so cause the requisite up-and-down movement of the needles in the operation of knitting.

Operation. The needle is lowered to knit, by what is called the stitch cam, which has a diagonally inclined edge, and thus moves the needle down as the cam cylinder revolves. The cam cylinder also carries a yarn guide through which the thread is laid in the hook of the needle just before the needle is moved down by the stitch cam. As the needle moves downward, the latch is pulled up by the loop on the shank of the needle so as to close the hook of the needle, thus safely drawing down a new loop through the old one. When the needle rises again, the yarn in its hook pulls Fiffi^i- stocking as it comes

open the latch and turns it down upon the

shank of tiie needle until the yarn has passed entirely below the latch, forming a loop around the shank through which, in turn, another loop is pulled down. Thus each needle pulls a series of loops, one through the other, forming a knitted fabric.

When the needle descends with a new loop the old loop is cast off over the closed hooked end of the needle, and forms a part of the tubular fabric which hangs down within the needle cylinder.

In knitting the tubular portions of a stocking, all the needles are in operation, and knit one course at each revolution of the cam cylinder. In knitting the heel or toe of a stocking, only a portion of the needles are in operation, and the cam cylinder is reciprocated, or moved first in one direction and then in the opposite direction. The heeland toe are in the form of a pouch or pocket, and they are knit by what is known as the narrowing and widening operation.

In this operation about one-half the number of needles are first raised to a higher level, or into an idle position, so that their butts will not be operated upon by the stitch cams. The other needles remain in an active position where their butts may be operated upon by the stitch cams. In the operation of narrowing, which then takes place, one of the active needles is shifted to a higher level, or to the idle series, at each reciprocation of the cam cylinder, by raising or elevating the
