SPECIFICATION forming part of Letters Patent No. 271,971, dated January 23. 1883.

(No model.)

To all whom ti may. concern:

Be it known that I, WARREN D. Hose, of Laconia, county of Belknap, and State of New Hampshire, have invented an Improvement in v Knitting-Machines, of which the following de-.

scription, in connection with the accompanyin g drawings, is a specification.

My present invention is an improvement upon the apparatus shown in my Patent No. I0 255,996, dated April 4, 1882, and has for its object to reciprocate the tappet-rings by the direct action of gearing, rather than by acamplate such as shown in the said patent. The knitting mechanism employed will be the same as in my Patent No. 220,924, October 28, 1879. Figure 1 represents in side elevation, with portions broken away, a sufficient portion of a knitting-machine to enable my invention to be understood; Fig. 2, a sectional elevation,par- 2o tiallybroken out; Fig. 3,abroken detail, showing a portion of the tappet-rin gs and part of the mechanism for moving them, with the upper end of rod 1%, to be referred to; and Fig. 4, a diagram of the-pattern which will be formed by the cam shown in the drawings, with the pins removed, however, from one of the tappet-rin gs. In this invention I have marked the different parts common to my Patent No. 255,996 with like letters, and hence I need not specifically 0 describe the operation of the said parts, as they are fully described in my said patent, further than to say that A represents the needle-cylinder; B, the dial-plate; B the cam-cylinder for the vertical needles; E F, the tappet-rings; t 1', their adjustable pins; D, the disk; h h, its

tappet-projections; N, the rack-bar; 0, gearwhecl; f, the pinion moved by the said gearwheel; g, a crank-pin thereon; O, the rotating thread-guide; p, a pinion on the shaft of the thread-guide; M,a cam; S,a sprocket-wheel; Q, a Jacquard chain; '0, a reciprocating bar or rod; K, pawl-lever; l, pawl; J, wiper; H, cogwheel; j 70, transmitting-gear, and I an eccentric, all common to thesaid patent. V

In the present drawings, in Fig. 2 I have also shown part of the rod R, common to my Patent No. 255,996. This rod will be lifted by the projections of the Jacquard chain Q, as in the said patent, and for the purposes described in the said patent, and also for the purposes in my Patent No. 220,924, dated October 28, 1879, so the same need not be herein further described.

In Fig. 3 I have shown the top of the rod B in place in the usualnotch between the rings E F, having the tappet-pins 'i, as in said patents.

Instead of the cam-plate P, which in the said patent acts upon arms extended from the said tappet-rings, I now provide each of the said tappet-rings, at its under side, with rack-teeth 0 (see Fig. 1,) suitable to be engaged by the gears 3 4, the gear 3 engaging the teeth of the inner tappet-ring, F, and the gear 4 engaging the teeth of the outer tappet ring, E.

The gears 3 at are secured respectively to sleeves 5 6, held in brackets 9 10, the said sleeves having also fixed to them respectively, outside the supporting-brackets, gears 12 13. The gears 12 13 are engaged by the teeth ofa 7o rack-bar, 14, connected with the upper end of the sliding rod or bar 0, referred to, it being guided in a guide,15. The rack will be drawn down and the foot of the rod 0 will be kept against the cam M by means of a spring, 16.

The cam M herein shown has four throwpoints to raise the rack-bar gradually and let iufall quickly, and when both tappet-ringsare employed such cam, by gradually lifting the bar 0, will effect such movement of the rings as to cause their pins to be gradually separated from each other a little further for each course of knitting entering into the figure, so that were the pins set at a distance apart to knit two stitches for the commencement of a spot the last course of the spot, by reason of the separation of the pins,might contain from ten to twenty stitches, thus making a nearly triangular spot,and when the bar drops from the end of the cam the short course for the next 9 spot will be commenced next to the broad part or base of the nearly triangular spot. By removing the pins from one of the tappet-rings, thus throwing it out of operation, the cam M, by gradually lifting the bar 0, will cause the tappet-ring which is yet provided with pins to gradually change its position with relation to the needle-bed, so that the pins will actuate the yarn-guide at a different point, or opposite different needles for eaohcourse of the spot or figure, thus inclining the figure gradually to the right or to the left, according to which tappet-ring is permitted'to retain its pins, thus making a figure of equal width from end to end, as in Fig. 4. The number .of pins in the tappet-rings will depend upon the number of times that the yarn-guide is to be shifted for each course of knitting, each change of the yarn-guide causing a yarn of different color to appear on the right side of the fabric, and the 4 distance between the said pins will depend upfrom it to come into operation after four stitches have been taken, when the yarn-guide will be again changed to present to the needle for the face of the fabric, say, a white yarn; but the next pin, or the one to again change the yarnguide to again present the blue yarn, may be at such a distance from the pin which caused the yarn-guida to present the white yarn as to permit the needles to make twenty stitches with the white yarn on the face of the fabric, so that each course of knitting would present four blue and twenty white stitches in successiononthefaceofthefabric. lhusitwillbeseen that by changing the pins toward or from each other, so as to move the thread-guide sooner or later, a great variety of figures may be produced, the figures depending for their outline upon the number of stitches made in each course by the yarns of different color.

The shape of the cam M may be varied at will, according to the shape of the figure to be produced upon the fabric being knitted.

By the employment of a gear, as described, to move the tappet-rings, I am enabled to operate the said rings more steadily and uniformly and with less friction.

I claim 7 1. The tappet-ring provided with teeth, and gear to engage the same, and the rack-bar, and connecting mechanism between the said gear and rack-bar, combined with means to move the rack-bar, substantially as described.

2. The thread-guide, rack-bar to move it. the disk D, provided with tappet-projections, and means between the-disk and rack-bar to move the latter, and a tappet-ring provided with teeth 0 the pins 2 on the tappet-ring, a cam, M, slide-rod, and rack, combined with a gear to engage the teeth of the tappet-ring,

and with connecting means between the saidgear and the rack-bar, substantially as described.

3. The two tappet-rings provided at their under side with rack-teeth, and the pins t", carried by the said rings, and a thread-guide and disk D, and means between the disk and threadguide to actuate thelatter, combined with the pattern-cam, means to move it, the sliding rack 14, gears 3 and 4, and intermediate gear between the said rack and gears 3 4, substantially as shown and described.

, In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
