SPECIFICATION forming part of Letters Patent No. 510,9 59, dated December 19, 1893. Application filed September 1,1890. Serial No. 363,670. (No specimens.)

To all whom. it may concern:

Be it known that I, SWITs OONDE, of Oswego, in the county of Oswego, in the State of New York, have invented new and usefullnr sections at intervals into the knitting body,

all as hereinafter more particularly described and pointed out in the claim.

In describing this invention, reference is had to the accompanying drawings, forming a part of this specification, in which, like letters indicate corresponding parts in all the views.

Figure 1 is an elevation of a portion of a needle cylinder illustrating in operative position by dotted lines one of the parts of the secondary feed of the preferable form of feeding mechanism for carrying out my method. Fig. 2 represents a top plan view of my improved feeding mechanism for carrying out my method, and a portion of the needle cylinder. Fig. 3 is a side elevation of the parts shown at Fig. 2, a portion of the needle cylinderbeing broken out for the purpose of more clearly illustrating the primary feed of said feeding mechanism. Fig. at is a front elevation of the detached primary feed. Fig. 5 is an inverted plan view of a detached portion of said feed. Fig. 6 is a sectional view, taken on line 0c-w, Fig. 4. Fig. 7 is a detail sectional View, illustrating a portion of the secondary feed, and Figs. 8 and 9 are, respectively, front and rear elevations of a detached modified construction of the primary feed.

In order to clearly describe my method I have illustrated, and will now proceed to describe a feeding mechanism,which is particularly applicable for carrying out the same, and forms the subject matter of a pending applicatim, Serial No. 363,538, filed August 30, 189

A represents the frame upon which is revolubly mounted a needle cylinder B formed with bearded needles I) and rotated by suitable gearing Cf from a shaft 0 beneath the table. The body of the knitted fabric is knitted by the cylinder in the usual manner, not necessary to herein further illustrate or describe, and the spots are formed by the primary and secondary feeds, which I will now describe.

The primary feed D for feeding the strand cl consists of a pair of rollers d d journaled in a bracket E adj ustably mounted at e upon a second bracket E in order to permit of a variation'in the approximation of the primary feed D and the secondary feed, presently described. These rollers d' (1* are mounted on shafts (Z d, which are actuated by the gears d d mounted upon said shafts and meshing with eachother. Power is transmitted to one of these shafts as d by a pulley cl driven by a belt 61 which passes over the guide pulleys d and the driving wheel (1 The yarn is fed from a suitable spindle or skein, not necessary to herein illustrate or describe, is thence passed through the guide f upon the table A, and through the hollow guide F, whence it issues between the rollers d d being thereby constantly fed forward toward the secondary feed.

At figures S and 9 Ihave shown a modified construction of a primary feed for use in carrying out my process in which the rollers d (1 are conically shaped and their actuating shafts d (i inclined and connected by bevel gears 71". k. In this modification the guide F consists of a depending plate f reinforced by a plate f having a perforation at its central portion and having its ends slightly lapped upon the rollers d d With this moditied construction I am enabled to approximate the primary feed more closely to the secondary feed, and thus feed yarn of smaller size than it is possible, or at least desirable to feed with the previously described construction of feed.

7 In order to adapt the rollers to yarn of different thickness, one of said rollers is mounted with a movable bearing G against which bears one extremity of a spring G',the opposite extremity of which is secured to the bracket E by the pin g and the adjusting screw 9 The secondary feed is so constructed as to feed the strand d at a greater speed than the same is fed by the primary feed, and the preferable form of said feed consists of the needles b of the needle cylinder B, and a burr wheel H loosely journaled on the inclined spindle h carried by an adjustable spindle 1h mounted in the bracket 1. This burr wheel H is of the ordinary construction, and is provided with burrs, which register with and engage the knitting needles I) for revolving the wheel H in the usual manner, and said wheel is so arranged as to catch the arm fed by the primary feed to which it is in close proximity, and in connection with the needles b to feed the same beneath the loops or beards of the needles I). When the advance end of the strand cl is engaged between the wheel H and the needles I), which feed the same at a greater speed than the primary feed D, the strand is broken or divided at a point in close proximity to the rollers (1' (Z and the small section engaged by the burr wheel and the knitting needles is fed by the movement of saidparts beneath the needle beards and. just beneath the main strand 1, Fig. 1. This main strand 1 is fed from a suitable guide 4, a portion of which is illustrated at Fig. 1 to the fabric by any desired means as by a burr wheel 2, Fig. 1, and when the needles engaging the same have passed the wheel H they operate in the usual manner to knit said strand 1 into the fabric, and to simultaneously knit the small section of the feeding; strand cl into said fabric. The usual depressor wheel 3, Fig. 1, may be usedfor depressing the fabric while the main strand 1 is beingfed to the needles I). As the needles I) are continuously revolved at a greater speed than the strand at when fed by the primary feed, a considerable portion of the knitting fabric passes the wheel H before the rollers d d feed the strandd sufficiently forward to be again engaged by the burr wheel H and the needles b, whereupon said feeding strand is again broken, and a second section is fed to andknitted into the knitting fabric.

It will be particularly notedthat the sole function of the burr wheelH is to feed in connection with the needles b, the small sections of. the feeding strand d to the knitting fabric, andthat said burr wheel does not otherwise aid in the knitting of the fabric. Y

J represents a depressor plate for depressing the knitting fabric after its passage from the depressor wheel 3, until after the small sections of the feeding strand d are fed beneath the beards of the needles I) engaged with said knitting fabric. This depressor plate is secured to a bar J, which is-adjustably mounted in a slot 2' of an upwardly extending arm I on the bracket I.

Upon reference to the foregoing description and the accompanying drawings it is obvious that the body of the fabric is knitted in the usual manner, and the spot forming strand constantly fed forward to the fabric by the primary feed; that strain is then applied lengthwise to the strand d by the secondary feed, which feeds said strand at a greater speed than the primary feed, and thereby breaks or tears the same into small sections; and that said sections are fed at intervals to the knitting fabric, and are knitted thereinto.

A particular feature of advantage accruing from the use of my method is that the weakest kinds of yarn can be readily fed by the slow feeding primary feed without liability of their breaking before engagement by the wheel H of the secondary feed. Indeed,I have ascertained by practical experience, that the ordinary untwisted roving can. be readily knitted by my improved method. By this improved method I am also enabled to knit a fabric having a series of spots therein arranged in rows, and I thereby produce a fabric of pleasing appearance, which can be sold readily with substantially no addition to the cost of production, since my process is very simple, and is readily carried out byia simple attachment to the'knitting'machine without involving change in its general construction.

I have also noticed, in carrying out my method, that the extremities of the several sections of the strand d, when broken, are

biased or inclined, so that the threads com- This is of particular advantage,

stitch or loop of the fabric,- and the longer threads by the next adjacent: stitches or threads. Indeed, in some cases, when the proportionate speeds of the primary and secondary feedsare suitable, it takes three or four stitches or loops of the body of the fabric to entirely secure or knit into the fabric the extremities of the short sections of yarn cl, and the sections thus gradually lose themselvesin the body of the fabric without an abrupt ending.

A fabric knitted by my improved method presents apeculiar mottled appearance, which is both novel and pleasing. As illustrated'in passing through the guide f in Fig. 3,1'preferably usetwo feeding strands of different colors or textures, and it is evident that by varying the colors and kinds of the strands of the spot forming yar.n,.a vast number of diversified designs are obtainable.

My method will be readily understood f-rom the foregoing description and uponreference to the drawings,but I do not herein limit myself to the describedconstruction of feed for carrying out the same, since it is evident that any other suitable construction may be used.
