UNITE STABS WALTER AIKEN, OF FRANKLIN, NIMV HAMPSHIRE.

KNITTING-MACHINE.

To all 'whom 'it may concern:

Be it known `that I, WALTER AIKEN, of Franklin, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Knitting-Machines; and I do hereby declare that the same are described and represented in the following specification and drawings.

To enable others skilled in the art to make and use my improvements I will proceed to describe their construction and operation, referring to the drawings, in which the same letters indicate like parts in each of the figures.

Figure l, is a plan or top view. Fig. 2, is a plan of the bottom. Fig. 3, is the under side of the top circle. Fig. 4, is a portion of the upper side of the lower circle. Fig. 5, is a section of the machine cut perpendicularly through the center.

The nature of my invention and improvements in knitting machines, consist in providing some sliding traversing` sinkers to push or press .the fabric knit olf of the needles between which the sinkers are operated, and in supporting the wheel that presses or holds the work or fabric knit back on the needles, by an arm bent or curved around to the under side of the wheel, so that the top of the pivot on which the wheel turns may pass freely under the needles.

In the accompanying drawings A, is a circular plate of metal provided with a flange B, to project down around the plate C, as shown in Fig. 5. The edge of the flange B, is provided with teeth acted upon by the gear D, so as to turn the plate A, and operate the machine. The shaft of gear D, turns in the stand E, fastened to under side of the plate C, as shown in Fig. 2. This shaft may have a pulley, gear or crank applied to it to turn it, so as to operate the machine, either by hand or power.

C, is a circular plate made in the form shown in the drawing with a rebate around its lower outside edgeas shown at F, in which the points of the screws Gr, Gr, travel which are screwed through the flange B, so as to hold the plate A, down to the plate C, while it turns on it when the machine is operated.

The plate C, is grooved on its upper surface for the needles H, and sinkers I, which are arranged alternately in it; the grooves for the sinkers being more than twice as deep as the grooves for the needles. The

needle F ig. 6, is made with a hook and latch iK, which falls down on the hook as the sinker pushes the stitches off of the needles, after the thread carrier or hole L,in the latchopener Z1, has supplied or laid the yarn in the hooks of the needles. The latch opener Z), is fastened to the circle A, and carried around by it. The ends of the shanks of the needles H, are bent at a right angle as shown in Fig. G, and the part so bent fits a score in the edge of the plate C, cut down from the needle grooves for that purpose. The sinkers I, are made of thin plate metal in the form shown in Fig. 7, and the lug J, projects above the top of the plate C, into the cam groove L, in the plate A, which groove traverses the sinkers I, that is the port-ion L', of the groove draws the sinkers back, so as to allow the presser wheel M, under the needles to push the stitches and fabric back on the needles beyond the ends of the latches, and at the same time the cam groove draws the sinkers back out of the way of the latch opener a, which passes along and delivers the yarn to the hooks of the needles, when the sinkers are pushed out by the portion L2, of the groove, so as to push the stitches forward, close the latches and push the old stitches over the latches ofi'1 of the ends of the needles, so as to form new stitches ofthe yarn laid in the hooks of the needles. After the sinkers have been pushed out by the part L2, they are drawn back by the part L3, to their normal position. It is necessary to attach a weight to the fabric knit to draw it down, and keep a proper tension on the stitches. The presser wheel M, is provided with small teeth, so as to roll freely against the fabric and it turns on a st-ud in the arm N, which arm is fastened to the circle A, as shown in the drawing and bent around or curved around under the ends of the needles and far enough below them to permit the presser wheel M, to t-urn on a stud projecting up from its lower end under the ends of the needles. There is a groove in the plate deep enough to allow a needle or 'sinker to be taken out which groove is filled by the key P, with a score in it to correspond with the cam groove L, in the plate A.

By curving the arm around so as to support the presser wheel from the under side is a very great advantage as it allows the use of a very small wheel, as the needles may project over its center when the wheel is 2. The sliding traversing sinkers arranged in the manner described in combination with stationary needles, as and for the purpose set forth.

3. Supporting the Wheel that presses or holds the Work or fabric back on the needles by an arm bent or curved around to the under side of the Wheel substantially as de- Y scribed.
