STRIPING MECHANISM FOR CIRCULAR-KNITTING MACHINES.

' SPECIFICATION forming part of Letters Patent No. 463,432, dated November 1'7, 1891.

d Application filed June 8. 1891. Serial No. 395,471. (No model.)

drawings, in which- Figure l is an'elevation of a circular-knitting machine fitted with my improvement; Fig. 2, a plan thereof, with ribbing-cam shown in dotted lines and parts in section; Fig. 3, a side elevation of a part of the machine gyFig. 4, an elevation of another part; Fig. 5, a view showing the shape of the main thread-guide Vand'latch-guard; Fig. 6,aview ofthe threadguide and latch-guard as formerly used. Figs. 7 and 8 illustrate the formation of the fabric on the ribbing-needles.

The object of the invention is to enable knitted goods having stripes running in the direction of length of the fabric to be made upon circular-knitting machines.

L L is the frame, carrying the vertical or frame needle-cylinder Z.

N is the frame cam-cylinder, which revolves around the needle-cylinder Z and is driven by beveled gear K from the shaft M in the known manner. is supported in the known manner upon the shaft D of the ribbing-cam disk P, which is carried by the arm D2 on the pillar D3. The frame C, attached to the cam-cylinder N, carries the main thread-bobbin S, the thread tof which is carried to the thread-guide Q upo the bracket R on the frame C.

To provide for the insertion of threads to form the stripes upon the fabric W at suitable places along, upon the usual ring A, which retains the frame-needles and is located at the top of the cam-cylinder N, are placed pins for carrying the small reels or bobbins b for the respective threads. On the ring A are also pillars c', carrying the rollers c, each adapted to revolve upon the pillar c', supporting it and arranged with its axis horizontal and in a radial line from the vertical axis X Xof the machine. Each roller carries the eccentrically-placed projecting tube o", through which the respective thread S is passed from the bobbin b. The roller c The ribbing-needle disk D has the flange or flanges c2, for a purpose hereinafter shown. The ribbingcams are revolved with the frame-cams by the arms B, connected to the sleeve J on the shaftD, and brought into connection with the frame camvcylinder N in the usual manner. The pin P connects the cam-disk Pto revolve with the arms B when'the latter are driven with the frame cam-cylinder N;

On one of the arms B is the sliding bar e, connected thereto by pins e and slots e2. On one of the pins e is pivoted the latch d, having the turned-over end c, adapted to take into a recess w in the sliding bar e and lock the same in its lowest position when desired. The tail of the latch d is connected to the tail of the plate e bythe spring p, so that the same spring lifts the latch by.drawing down its tail, and'lifts the sliding bar e into its highest position when not retained by the latch d. In this highest position of the sliding bare the projection f thereon, which may be of leather, stands in a position where, during the revolution of the arm B, this projection f touches the lowest lying part of the iiange or flanges c2 of each wheel c, so that the wheel is revolved for an appreciable distance. On the frame C is a similar sliding bar g, attached by pins and slots, and having lthe projection 7L of the same nature as the projection j", but intended to act upon the upper lying part of the flange or flanges c2 of each Wheel c, and thus act to revolve each wheel in a direction contrary to the motion imparted by the projection f. The action of either lone of these projections, as desired, will revolve the wheels c so as to bring the thread s, projecting from the tube fr thereon, into engagement with the latch of the rib-- bing-needle k, which stands opposite the tube r. By this means the respective ribbing-needle which has been pushed forward to receive the thread by means of the cams will receive both the main thread t in the usual'way and the stripe-thread s, the latter, however, lying in front of the former, so as to show upon the outside-of the finished fabric. The other pro# jection will operate to return the roller to its first position, while the needle draws the loop and throws on? the standing loop in the usual manner. The next rotation will again loop the respective thread s in the same manner ICO over the sante needle, so that the second loop is formed in like manner. By successive 1'0- tations of the ina-chine stripes are produced longitudinally with the fabric at or upon those ribbing-needles 'which are respectively opposite the rollers c. By suitable arrangement or grouping ot the rollers e variouspatterns of stripes may be produced.

Interrupted stripes may be produced by setting the stripe mechanism out of action during the desired number of rounds by Inoving one or both projectionsf 7L out of action. The bar g is held outof action,when desired, by lifting the saine and securing it in its upper position by screwing down the screws on which it is guided.

I claim as lny inventiond l. In a knit-ting'niachine for the manufacture of knitted goods having longitudinal or diagonal stripes or the like, the combination of a main thread-guide, a series ot' stationary auxiliary thread-guides located,as described, with regard to the needles on Which the stripe or pattern stitches are to be knitted, a projection adapted to rock said auxiliary threadguides, whereby their threads become engaged with the said needles, and a second projection adapted to return said auxiliary thread-guides to their original position, and

means for supporting the auxiliary threadguides and for supporting and actuating the main thread-guides and the two projections in combination with a projection adapted to rock said Wheels in one direction, and a second projection adapted to return the said wheels to their first position, and means for supporting said wheels c and for supporting and actuating the tivo said projections, substantially as and for the purpose set forth.

3. In a circular-knitting machine, a ring A, having pins for thread-spools h, and threadguides c thereon, located, as described, with regard to the needles on which the stripe or pattern stitches are to be knitted, in combination with the canrcylinder provided With the bars e and g, having projections j" and h and rotating with the cams, substantially as and for the purpose set forth.

In Witness whereof I have signed this speciiieation in presence of two Witnesses.
