$PECIFICATION forming part of Letters Patent No. 510,958, dated December 19, 1893.

Application filed August 30,1890. Serial No. 363,538. (No model.)

by a feeding strand is divided or broken into' sections, which are fed at intervals to the knitting fabric; and to this end theinvention consists, essentially, in a pair of feeds for feeding the same strand into the fabric, one of said feeds being arranged to feed the strand at a greater speed than the other feed for continually breaking the strand and feeding the same in sections at intervals.

The invention also consists in the detail construction and arrangement of the feed for continually feeding said strand to the feed of quicker movement, and in the detail construction and arrangement of the parts, all as hereinafter more particularly described and pointed out in the claims.

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

Figure l is an elevation of a portion of a needle cylinder illustrating by dotted lines one of the parts of the secondary feed of my invention as in operative position. Fig. 2 represents a top plan view of my improved feed and a portion of the needle cylinder. Fig. 3 is a side elevation of the parts as shown at Fig. 2, a portion of the needle cylinder being broken out for the purpose of more clearly illustrating the primary feed. Fig. 4 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 ill-d3, Fig. 4. Fig. 7 is a detail sectional view, illustrating the construction of the secondary feed. Fig. Sis an isometric perspective of the detached movable bearing for the lower end of one of the actuating shafts of the primary feed. Figs. 9 and 10 are, respectively, horizontal and vertical secthe upper extremity of said shaft; and Figs.

11 and 12 are, respectively, front and rear elevations of a detached modified construc tion of the primary feed.

A represents the frame of desirable form, size and construction, supported upon which is a knitting machine also of desirable form and construction, the one illustrated being a circular bearded-needle knitting machine, in which E represents the cylinder, and h the bearded-needles.

0 represents a shaft from which motion is transmitted by any desirable form of mechanism C to a shaft 0 by which the cylinder B is revolved.

The feeding mechanism consists of the pri mary feed D and the secondary feed. The latterfeed feeds the strand (1 engaged thereby at a speed greater than the primary feed D, and consequently said strand is continually broken or divided into sections which are fed successively into the fabric by the secondary feed, whereupon the needles 12 forming a part of said secondary feed, knit the separate sections of the feeding strand d into the fabric.

The primary feed I) preferably consists of a pair of rollers cl and d journaled in a bracket E, which is provided with a rear inclined bearing face 6 mounted upon the inclined bearing face 6 of a bracket E secured to the table A. The bracket E is adj ustably secured in position upon the bracket E by means of a set screw 6' having its upper extremity mounted in a slot 6 in the rear exin position by a set screw a having one end mounted in a slot 6 in the rear extremity of said bracket and the other screwing into the top face of the frame A. By means of the adjustment of the brackets E E the rollers d d are readily approximated the desired degree to the secondary feed. These rollers d d are preferably actuated by means of suitable gears ti and d meshing with each other and mounted on the shafts d d of said rollers. Motion is conveyed to one of said gears as d by means of a pulley (1 which is mounted on the shaft (1 and is rotated by a belt d passing over guide pulleys d and the driving or skein, not necessary to herein show or lie scribe, through a guidefto the guide F at the rear of the rollers d (1 whereby the yarn is fed between the rollers, as best seen at Fig. 5.

In order to adapt the primary feed to different thicknesses ofyaru ,the lower end of the shaft of one of said rollers, and preferably the shaft d of the roller d is mounted with a movable bearing G, which is guided in the bracket E. This bearing G consists of an upright portion g mounted in a cut-out g in the shaft bearing of the bracket E and formed with a curved face g adapted to bear against the shaft 61 Projecting rearwardly from the upright portion g are lateral arms g mounted in cut-outs g in the bracket E for preventing upright displacement of the movable bearing G. The free extremityg of a spring g bears against one of the arms 9 of the movable bearing G, and the opposite extremity of said spring 1s secured to an arm of the bracket E by a dowel pin 9 and an adjusting screw g As best seen at Figs. 9 and 10 the upper end of the shaft d is permitted to move slightly by means of'a sliding block d mounted in a slot (i opening from the journal bearing of said shaft, and is prevented from undue movement by means of a set screw 61 having its inner extremity arranged to make contact with said block. The block (1 is held in position by lateral arms 01 provided thereon and movable in slots d in the bracket E.

For the purpose of constantly clearing the rollers cl and d of all fuzz from the yarn I provide the wipers f, which bear against the outer portions of their peripheries, and preferably consists of a spring metal for permitting the adjustment of the rollers.

The secondary feed as previously stated is so constructed as to feed the strand d at a greater speed than the same is fed by the primary feed, and, as here illustrated, I have shown this secondary feed to consist of the needles I) of the cylinder B, and a burr wheel I-I loosely journaled on the inclined spindle 71* carried by an adjustable spindle h mounted in a bracket 1. This burr wheel H is of the ordinary construction and is provided with burrs which register with and engage the knitting needles for revolving the wheel H in the usual manner, and said wheel is so arranged as to catch the yarn fed from the primary feed to which it is in close proximity and in connection with the needles I) to feed the same beneath the beards b of the needles b. When the advance end of the strand dis 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 d LP, and the small section engaged by the burr wheel and knitting needles, is fed by the movement of said parts 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, mounted on a suitable support, not illustrated, and, when the needles engaging the same have passed the Wheel 1-1, they operate in the usual manner to knit said strand 1 into the fabric and to simultaneously knit the small sections of the feeding strand 01 into said fabric. The

usual depression wheel 3, partially indicated by dotted lines, Fig. 1, may be used for depressing the fabric while the main strand 1 is being fed to the needles I). As the needles I) are continously revolving at a greater speed than the strand d when fed by the primary feed, a considerable portion of the knitting fabric passes the wheel I-I before the rollers d (I feed the strand dsul'ficiently forward to t 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 and knitted into the knitting fabric.

It will be particularly noted that the sole function of the burr wheel H is to feed, in connection with the needles Z), the small sections of the feeding strand d to the knitting fabric, and that said burr wheel does not otherwise aid in the-knitting of the fabric.

'J represents a depressor plate for depressing the knitting fabric afterits passage from the depression wheel 3 until after the small sections of the feeding strand (2 are fed be neath the beards of the needles I engaged with 'said knitting fabric. This depressor plate is mounted on a bar J supported on an upward extension or arm I of the bracket I. The inner end of a screw j is screwed into the rear extremity of the bar J, and the outer end of said screw is passed through a slot 1' in the upwardly extending arm I, and interposed between the head of said screw and the adjacent or rearward face of the arm I is a washer 3' whereby, when the screw j is turned, the bar J is firmly secured in position.

At Figs. 11 and 12 I have illustrated a modified construction of my invention, in which the rollers d cl are conic'ally shaped and their actuating shafts d and d are 'inclined and connected at their outer extremities by bevel gears 70 and k. This construction enables me 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 previous construction of my invention. In this modification the guide F consists of a IIC depending plate f reinforced by a plate f having the perforation f at its central portion and having its opposite extremities slightly lapped upon the wheels (2 and (1 I have ascertained, upon practical operation, that my peculiar construction of feed is particularly adapted for feeding untwisted roving to the needles, owing to the slow operation of the rollers d and (P, which obviate all breakage of the roving.

The feeding strands of the fabric fed by my invention may be diiferently colored, and the short sections fed at intervals thereto then give a peculiar mottledappearance to the fabric, both novel and pleasing, and allow of numberless designs subject to the choice .of the operator.

The operation of my invention will be readily understood from the foregoing description and upon reference to the drawings, and it will be noted that my improved feed is in the nature of an attachment to the ordinary knitting machine, which is readily placed in or removed from operative position. It will also beunderstood that the construction of said feed is very simple, and its operation is certainand efiective.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The herein described feed for knitting machines, the same consisting of a continuously operating primary feed for feeding a strand, a secondary feed for feeding to the fabric the strand fed by the primary feed at the same time said strand is being fed by the 7 primary feed, and means to operate the primary feed and to operate said secondary feed tofeed said strand at a greater speed than the primary feed is simultaneously feeding the same, whereby the strand is divided into a number of small sections fed at intervals into the knitting fabric, substantially as and for the purpose described.
