Specification forming part of Letters Patent No. 169,331, dated November 2, 1875; application led June 15, 1875.

To all whom t may concern Be it known that I, CHARLES J. APPLE- TON, of Philadelphia, State of Pennsylvania, have invented a new and Improved Knitting- Machine; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this speciflcation, and the letters of reference marked thereon, in which the same letter represents the same thing in each figure.

This invention relates to certain improvements in knitting-machines; and consists of through the center of Fig. 1.

Referring to the drawings, A represents the welt-cam, B, the ratchet; C, the patterncam; D, the shaft for pulleys l 2 3 4; E, the Welt-lever post 5 E', the spring-welt lever 5 F, the driving-gear; g, the catch and dog; H, the dial-ring, J, the cam-ring; K, the needle-cylinder, M, the Ybrace t'o hold cap and dial; N, the cap; O, the dial; P, the collar on shaft; g, pin to move slide R; S S, the slide-boxes; S', the ratchet-pawl to work ratchet B, T, the spring on shaft D 5 U, the bed-plate; V V, the pillars holding brace M5, W, the collar working against cam C; K X, the shaft-lugs Z, the ratchet and' cam-shaft; Z', the belt-shifter.

One object of my invention is to produce, at the same time, two striped knit fabrics with selvage sides, of any desired pattern, on a circular knitting-machine, with a single feed for each fabric, the fabrics being similar to hand-loom Work. Another object is to produce Welts on each fabric, automatically, at pleasure.

I accomplish these objects by giving the cam-ring an oscillating as Well as at times a circular motion.

On a section of the needles in the cylinder and dial yarn of one color is placed, and on another section yarn of a different color, and the yarn changes sections at determined revolutions of the cam-ring, so that each section of needles knits rst one color and then the other.

The operation of the machine is as follows: The Workbeing on the needles, shaft D turns gear F, which revolves cam-ring J until pin g strikes ,slide R, which moves belt-shifter Z', so that the open belt on tight pulley l is moved upon loose pulley 2, and the cross-belt on loose pulley 2 is moved upon tight pulley 3, and cam-ring J is thereby reversed, and revolves in the opposite direction until pin q strikes slide B.. rlhe cam ring J continues to revolve back and forth, as described, until slide R, by pawl S',"moves ratchet B on shaft Z, so as to cause pattern cam C to push against collar W and move the pulleys on shaft D at the same time that slide B moves the belts in the same direction. The belts are consequently not shifted, and cam-ringJ makes an entire revolution before itv is reversed, moving the yarn of one color upon the section of needles previously occupied by the other color.

The welt-producing mechanism acts thus:

' The welt-cam A on shaft Z, moved by ratchet B, depresses the inner end of lever E' by lifting the other end, so that the inner end strikes the dog and catch g, detaching dial-ring H from the cam-ring J, so that the dial-needles cease to work, and plain knitting is done by theA needles operated by cam-ring J until dog gag-ain enters its catch on dial-ring H, when the dial-needles Will be again thrown into action, and both sets of needles will knit, the plain knitting having formed the Welt.

The action of the needles is the same as in vthe Pepper and other ribbed knitting-machines.

What [claim as my invention, and desire to secure by Letters Patent, is-

1. The combinatiom'with the needle-cylinder K and dial O, of the cam-ring J and dial-ring H, constructed substantially as described, so that ribbed or plain work may be produced automatically, at pleasure, as set forth.

2. The, combination of a. cam-ring, J, slide l 1?., 1pulleys1 2 3 4, and lpattern -cam C, 'mlapted to Operate together, substantially as described. `Y

3. Four sliding pulleys, alternately tight and loose, applied to a. shaft, D, and coulbined with shifting mechanism, as described,

whereby circular and semicircular movements maybe imparted to the'cmfriug J, et `pleasure, substantially as specified. Y o
