-so taken is kn Fig. 2, full lines, show the switch and cams the positions they will occupy when the inder commences its movement in the dig. 1, Fig. 4 showingvthe position of the bridge, it resting oni-cam f ready for the needle-butts to ride up the incliued upper side of `cam f, and at the end of cani f, in Fig. 2, the b shift the switch m, so that point l will meet end p of cam g, lines, Fig. 2, when the needle-butts will'pass down the lower side of g. (See Fig. 4.) These cams are adapted to actuate the needles to knit properly when the cam-cylinder moves in either direction.

This switch, it will be noticed, is moved onin cyl ly by the b utts of the needles, no other devicesl being necessary.

The carrier r consists of a ring fitted to reproeate on the plate Z1, aud-provided with ci Y posts s and a bar, t, to which are fitted a number ofthread-guides, u, the number of thread- .guides depending upon the width of the stripes to be knitted and joined at their sel- `In this instance I have shown ten thread'- guides, adapted to operate in connection with' fifty needles7 therefore I use on e guide for each set of tive needles, and the stripes or strips ried by the guide; but in addition to present ing its thread to its own live needles, each thread-guide, at one of its extreme movements, moves far enough to allow its caught by the first needle of the the needle of the adjacent set, and the loop itted by such needle, with its needle connecting the loops of the two strips or stripes, the longitudinal row of double loops, knitted by this needle, presenting two colors, and sort of a welt or cord. Should yarns of one color be used, the strips or will be connected by a welt or cord formed by the double stitches.

Looking at Fig. l, the thread-guides u are all at one side of the different sets of needles, to which they are to deliver threads, and each thread-guide rests, commencing at the end w of the needle-bed a, just beyond each fifth needle. One end of the projection 'u' rests against one side of shifter, which it moved to the position shown in Fig. 1, at thecompletion of the movement of the cylinder in the direction of arrow 2. Motion being imparted to the cam-cylinder d, in the direction of arrow 1, the needles are caused to knit the thread laid intol or near their hooks when the carriera. and threadguides were moved into the position shown in Fig. 1, and the cam-cylinder continues to rotate until the end a) of the projection c meets the opposite or left-hand side of the arm w, then the projection turns the carriershifte'ri on itsv supporting-pin b', and causes the utts meet point Land:

In some instances I propose to use threads alike asito quality and color for the manufacture of gloves, moving the carrier and thread guides/substantially as above described, to form the hand portion, or a fabric for the hand or palm and wrist portion, and on reaching a point where fingers are needed I will change the`movement of the threadguides so that they will not move far enough to lap their threads on -the needles of an adjacent set, and this Aaction (the rest of the machine operating as usual) will produce narrow strips of fabric disconnected at the selvagest and suitable for lingers, such narrow strips.

gers. This change of distance, and over, oneless needle, may be made by the stop c1, so that the pins will engage the stops el and stop the carrier as soon as thethread-guides lay their threads inztheneedles: of theirown set only. This provision of.l moving the thread-guides to connect, and at other times not to connect, also-,theselvages of the strips, permits a fabric to be knitted, composed of portions more or less wide, connected by means of narrow strips.

By using a number of thread-guides, with a thread for each, as described, I am enabled to knit rapidly a fabric composed of strips orstripes of contrasting colors, each strip being-.,-

. knitted by a single and unbroken thread@ The driving-shaft g( has attached; to it ai liub, h', having two fixed pulleys, ibi/f,- andi turning on the hub loosely isAapulgley, j.

Friction devices ai, two or more, and of an y v suitable construction, are connected with arms o attached to the hub h', and the force ofthe pressure of the friction devices -on the hub m is regulated by screws p. The thread-guides might move over more than one needle of an adjacent set, and thicken the fabric andincrease the size of the welt. The wheel c and hub m are held against longitudinal movement inthe direction of the shaft.

I intend to drive this machine by power and by the plain or crossed belt, according to which one is in action. Suppose the straight belt on pulley t" to be in action, then the crossed belt will rest on theloose pulleyj, and the cam-cylinder will be moved in direction of arrow 2 until A a stop on the, cam-cylinder strikes stop el; then the cylinder cam no longer rotates, or can the wheel c and hub m connected therewith,

but the pulleys and hub h' continue to move,'-

the friction devices slipping about hub m', and during this time the shaft g', through its screw Z', acting on the screw-thread in the hub m', which cannot move longitudinally, forces the shaft g and pulley iz" j', passing the pulley i through the plain belt held by th'end of the stationary belt guide, and placing the loose pulley j into the plain belt, and the same movement passes the loose pulley through the crossed belt then resting on it, and brings the fast pulley i into it, and then the machine will be reversed. With the reversal of the motion of the shaft h', the cylinder not being held against rotation ingthe direction of arrow 1, will quickly rotate until a stop on the cylinder again meets the stop e2, when the'cylinder 'will again be stopped, and the longitudinal movement of the shaft and pulleys will be the j reverse of that just described.

This mechanism might be applied to reverse the action of other than knitting-machines,

dles; nor do I claim the combination of such a movable switch, with the needle elevatingand depressing cams, as such features and combinations form the subject of another applica-k tion led by me in the Patent Office October 28, 1875.

`I claiml. A needle-bed, adapted to receive reciprocating-needles, and cams and a movable switch I to actuate such needles at each reciprocation of the cam-cylinder, in combination with a carrier, connected with and operated by the cylinders and provided with two or more thread-guides, whereby independent threads may bedelivered automatically and simultaneously to sets of two or more needles, and be 3. The combination, with the cam-cylinder stop t' and carrier for the thread guides, of a vibrating carrier shifter moved by the stop on the cylinder at the end of each reciprocation/of the cylinder, substantially as de-.

scribed. A

4. The combination ofthe cam-cylinder and its driving-gear and hub, with a screw-shaft, fast and loose pulleys, friction devices and stationary belt-guides, whereby a straight and crossed belt may operate to reverse the motion ofthe cam-cylinder, substantially as described.

5. The cam-cylinder and its stop, adapted to meet a stop, e1, in combination with the driving-gear e, hub, friction device, and driven shaft, whereby when the cylinder arrives at one extreme of its motion the driven shaft may continue its motion without injury to the machine.
