KNITTING-MACHINE.

SPEQIFICATION forming part of Letters Patent No.407,960, dated July 30, 1889.

T0 aZZ whom it may concern:

Be it known that I, EDWARD MURBY, of Detroit, county of Vayne, State of Michigan, have invented a new and useful Improvement in Knit'ting-Maehines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to certain new and useful improvements in knitting-machines; and it consists in the combinations of devices and appliances hereinafter specified, and more particularly pointed out in the claims.

My invention is designed more especially as an improvement upon United States Letters Patent granted to me August 5,1884, No. 302,928, although I do not limit my present invention to its application to my said patented machine, but contemplate as coming within the scope of my invention the application of my improvement to any machine of this class to which these said improvements may be found adapted. In my said patent the improvement consisted in a looping attachment for the manufacture of socks and other articles with an interior lining of loops knit into the fabric, so as to constitute an integral part thereof. V

I-Ieretofore in constructing the heels and in widening and narrowing for the toes of socks, also the finger ends of mittens, &c., it has been found impracticable to provide an integral looping at these points, and the looping has had to be put in by hand to complete the article after work thereon was finished.

My present invention contemplates im provements whereby said looping may be formed upon the heels and toes of socks, finger ends of mittens, &c., integral with the fabric itself in the process of its construction. These improvements are also designed to facilitate the construction of socks and analogous articles, as embraced in another pending application, Serial No. 199,942, filed April 23, 1886, wherein threads of yarns of different materials or color are so knit'together that the Application filed December 28, 1886. Serial No. 222,835. (No model.)

interior of the article is faced with one material and the exterior is faced with another material, as set forth in said application.

Prior to my present invention it was also found impracticable to so face the exterior and interior surfaces of the fabric'in forming the heel and toe or finger ends, as the case may be; but my improvements herein described are designed to accomplish these results in the construction of the heel and in widening or narrowing, thus making the fabric uniform throughout.

I have shown in the accompanying drawings a machine embodying the features ofmy said patent with these improvements applied thereto, in whicli Figure 1 is a plan vieiv of a knitting-machine embodying my invention with parts in section and parts removed, and Fig. 2 a vertical section illustrating my invention.

I carry out my invention as follows: A is the supporting-frame; B, the needle-cylinder; C, the surrounding cam-cylinder, and D the crank-shaft geared in any ordinary manner to rotate the needle-cylindle.

1) represents the needles; E, any ordinary yarn-guide for feeding one of the yarns e.

F is a stem connected witharemovable arm G and made adjustable therein by an adjusting nut or cap, as shown at F, so that it may be raised or lowered upon the said arm, the said stem being non-rotatable.

H is a rotatable plate or disk located upon the said stem and supported thereon by a collar 19 and nut 20 on the lower end of said stem, said disk being provided with grooves, as indicated at h, radiating from its center upon its upper surface, said grooves containing a series of points h located therein, said points being arranged laterally to the line of the movement of the needles and constructed with a projecting lug or heel 7Z2.

I represents a stationary camplate provided with a cam-groove, as shown at I, said groove engaging the lugs or heels of said points.

H represents lugs or ears upon the lower side of the disk 11, which are made to engage corresponding ears B within the needle-cylsaid .portion of operative needles.

inder, so that when the needle-cylinder is revolved the disk-will be carried with it when located in place.

J represents a collar located upon said stem and made non-rotatable thereon in any proper manner, as by'set-screws M. (Shown in the drawings.) v

My invention consists in adding to these combinations of devices a yarn-guide K, swiveled upon the stem, so that its position may be shifted backward and forward by the operator, as shown in full and in dotted lines in Fig. 1, so as to carry the thread and feed it to the needles from either direction, as may be desired.

It is. understood that in making the heel and in widening and narrowing only a portion of the needles are in operation, the needle-cylinder being vibrated backward and forward to form the heel and to narrow or widen upon 7 For this operation the yarn fed through the guide E is fed properly to the needles for work in either direction. hen, however, the looping attachment is desired to be used in connection therewith, the yarn L is to be fed so that it will be engaged by the points h and brought down by the needles to form the stitches, said points serving to hold back the yarn and cause it to leave the loop hanging thereon, and it is found necessary, in order to form these loops in the fabric when only a portion of the needles are operative back and forth, that the yarn L should be fed from the corresponding direction in which the needles are to work-11 6., as shown in Fig. 1, if the needles are to work successivelyin the direc-' tion of the arrow, the yarn-guide may feed the yarn from the position indicated in full lines. 0n the other hand, if the needles are to operate from the opposite direction, the yarn mustbe fed from the guide with the latter in the posit-ion indicated in dotted lines. Consequently, as the crank-arm D isthrown to and fro to operate the needles first in one direction and then in the other in the usual manner, the yarn-guide K must be successively thrown backward and forward, so as'to feed the yarn first in one direction and then in the other. This motion of the yarn-guide K may be accomplished by hand,the operator throwing the guide into the position shown by full lines or that shown by dotted lines,

according to the direction of the travel of the needles. In this manner I find that the loops can be integrally constructed in widening and narrowing'an d in the construction of the heel. In case it is desired to construct an article without the loops, but with the internal and external facing of different materials, asspecified in my above-mentioned application, the plate H with the cam-plate I and the points engaged therewith are made inoperative or are removed entirely from the stem.

Ordinarily where a machine is fitted for manufacturing one or the other of the abovementioned varieties of articles the stem would be provided with or without the disk or camplates, as the case might be. Should the machine be devoted exclusively to the manufacture of the double-faced articles, as above 'mentioned, the stem would need only to be provided with a collar J, the disk H and plate I being omitted altogether.

It is found that the vibratory yarn-guide K, so far as its functions are con.cerned,serves equally well to feed the yarn to the portion of needles operative in the construction of heels, toes of socks, &c., either for the double-faced goods or for the looped goods, it being found necessary in making the double-faced goods to feed the yarn L to the needles in the direction in which they are operated. So in making the heels and in widening and narrowing of double-faced goods the yarn K is shifted backward and forward as the crank-shaft D is shifted to first work the needles .in one direction and then from the other. In this way the yarn L is carried to the needles in a manner to accomplish the desired results.

I do not limit myself to any specific construction of the guide K, the chief requisite being that it be made vibratory. As shown, however, in the drawings, Iprefer to construct it of three partsviz., an arm 7c, engaged upon the stem F and grooved, as shown at k',.t.o receive a slotted angular arm k made adjustable thereupon, as by means of screws passed through the slot of said angulararm into the arm I This angular arm is provided at its lower end with the slotted guidepoint It, adj ustably connected therewith by means of a screwk passed throughthe slot of the guide-point into the lower end of said angular arm. In this manner the point 10 may be raised or lowered and the arm 10 adjusted toward or from the stem F to feed the yarn exactly as desired.

To limit the vibration of the guide K, the collar I is provided with stops M M, located upon either side the guide. The guide may be held in place upon the stem by a washer N, provided with a set-screw n. This washer evidently may be set down so as to properly hold the guide wherever it is put as it is shifted.

As the yarn L is to beshifted to and fro, it is obvious that a suitable device must be provided to take up the slack when the shifting is effected, as is shown in Fig. 2 at 0.

During the knitting process, other than when narrowing and widening, the guide K may be adjusted to a proper position and used without shifting. Thus, supposing the needles to be operating continuously in the direction of the arrow in Fig. 1, the guide K may be adjusted to the position shown in full lines and rigidly secured in this position by turning down the nut or washer N. The reciprocatory movement of the guide-arm K is only necessary when the needles are operated alternately in one direction and then in the other.

I do not wish to be confined to any partic- IIO ular take-up device; but the one shown for taking up the slack in the yarn consists of a bar 0', having a suitable support 0 to which it is pivoted toward one end, as shown at 0 its rear extremity being engaged with a spring Q, fastened at one end to the supporting-rod Q, as shown in Fig. 2. The letter 0 designates a pivoted clamp, under which the yarn is passed, and which operates to hold the yarn and prevent its escaping from the spool when the take-up arm 0 is thrown upward by the action of the spring.

That I claim is 1. The combination of a vibratory yarnguide, a looper attachment comprising a stationary cam-grooved plate and a rotatable disk provided with a series of radiating points or fingers having heels that engage the camgroove, and a central stem on which said guide and looper attachment are located, substantially as described.

2. The combination, with the central stem F and a vibratory yarn-guide swiveled about said stem, of a looper attachment supported on said stem and comprising a stationary camplate provided with a cam-groove, a rotatable radially-grooved disk, and a series of radiating points or fingers having heels that engage the cam-groove, substantially as described.

3. The combination, with a centrally-supported looper attachment comprising a stationary cam-grooved plate, a rotatable disk, and a series of radiating points or fingers carried by said disk and having heels that engage the cam-groove, of a yarn-guide provided with a guide-point, means for adjusting said point in a vertical direction, and means for adjusting it in a direction toward and from the center of motion of the looper attachment, substantially as described.

4. The combination, with a looper attachment comprising a stationary cam-grooved plate and a rotatable disk having a series of radiating points or fingers engaged with the cam-groove, a vibratory yarn-guide, and the central stem on which said guide and looper attachment are located, of a collar surrounding said stem and provided with stops to limit the vibration of said guide, substantially as described.

5. The combination, with a looper attachment comprising a stationary cam-grooved plate, a rotatable disk, and a series of radiating points or fingers engaged with the camgroove, of a vibratory yarn-guide and a takeup device, substantially as described.

6. The combination, with the central stem F and a vibratory yarn-guide located on said stem, of a binding device to hold said guide in any required position, substantially as described.

'7. The combination, with the stem F, of a vibratory guide engaged thereon, said guide comprising an arm is, an arm k adjustably mounted on the arm 70 by set-screws, and the point 70 adj ustably engaged upon the arm k by a set-screw, substantially as described.

8. The combination, with the needles and a stationary yarn-guide E for feeding yarn to the needles, of a'centrally-supported looper attachment comprising a stationary camgrooved plate, a rotatable disk, and a series of radiating points or fingers carried by said disk and having heels that engage the camgroove, and an independent vibratory yarnguide K for feeding a separate looping-yarn to the needles, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
