RIB-KNITTING MACHINE.

Specification of Letterslatent.

` To all whom 'it may concern.' j

Be it known that I, JOSEPH D. MonLuY, a

citizen of the United State/s, residing in. Utica, New York, have invented certain Im-' provements in Rib-Knitting Machines, e of which the following is a specification.

My invention is intended especially for use in connection withv rib knitting machines of line gage, the purpose of my invention being to prevent interference of the needles, or

ofthe latches of the needles, of one set, with the needlesgor the latches of the needles, of the other set-,in the operation of the machine. This ob'ect I attain in the manner hereinafter set orth`,reference being had to the accompanying drawings, in' which- Figures l, 2, 3, 4, 5 and 6 represent suflicient of the operative parts of a rib knitting machine to convey a proper understanding of my invention, the various figures showing said operative parts .in different positions assumed by them during the knitting operation; Fig. 7 is a view of one-half of the machine, partly in top or plan view and partly in horizontal section, through the dial cam rings; Fig. 8 is an inside elevation showing one set of cams of the cylinder cam ring developed in a flat plane, and Figs. 9 and 10 are views similar to Fig. 4, but illustrating modifications of my invention.

My invention is equally applicable to straight machines or Ito circular machines but in the accompanying drawing, I have illustrated it in connection with a circular machine.

Referring first to Figs. l to 6 of the draw'- ings, l represents part of the needle cylinder of the machine having vertically guided needles 2 part of the needle dial having horizontally guided needles 3 part of the cylinder cam ring, and 4 part of the dial cam ring, all of these parts being constructed and operated in the usual manner except as to the timing of the movements of the cylinder and dial needles, as hereinafter explained.

The cylinder and dial may be the stationary members of the machine and the cylinder cam ring and dial cam ring the rotating members, or the reverse construction maybe adopted, as desired. A

Mounted upon the needle cylinder l is an outer annular dial 5. in which are radially guide loop-receiving points 6, equaling in number the dial needles we and in line rau ially therewith and with the spaces between the cylinder needles a1. These loop-receiving points are acted upon by cams carried by an annular cam ring 7 which is mountedupon the dial-5 and is caused to rotate if said dial is stationary, or 'is held against rotation if said dial has rotary movement. The loop-v receiving points 6 have butts 9 which travel 'in a cam groove 10 of the ring 7, said cam rate/atea oet. 1,1912.

are at this time held in the retracted posi- I tion, asshown in Fig. 1, instead of being projected, as in an ordinary rib knitting machine., Before the cylinder needles are retracted so as to draw their stitches, the loop-receiving points 6 n are projected as shown in Fig. 2, to such an extent thattheir inner ends occupy the spaces between `the cylinder needles, whereby, as the latter are retracted so as to .cast the previous stitches and draw stitches of the fresh yarn,'loops of' the latter will be formed over the inner portions of the projected points 6, as shown in Fig. 3, in the same manner that they would have been formed over the Shanks of the dial.,

needles if the latter'had been projected in@I the ordinary manner. The inner ends of the" loop-receiving points 6 are now raised by the action of the cam 12, as shown in Fig. 4, the cylinder needles, by preference, rising correspondingly as there illustrated, and the dial needles are projected so that their outer portions pass beneath the points 6, and through the loops of yarn carried by said points, the same movement also clearing the l, stitches -`on said dial needles, as shown 1n Fig. 4. The points 6 are now retracted so as to castltheir loops onto the dial needles, this retraction of the points4 being, by preference, accompanied by a downward movement of the cylinderl needles so as to draw' the transferred loops into the hooks and in front of the latches of the partially retracted dial needles, as shown in Fig. 5, and the retraction of said dial needles then continues until they have cast their stitches and drawn I new stitches as shown in Fig. 6, the cylinder1 needles preferably rising to permit. such draft without imparting undue tension to the yarn.

. In ne gage rib knitting machines in which both the cylinder and dial needles are projected at the same time to receive the knitting yarn, diiiiculty has been experienced vbecause of the contact of the latches ot' one set of needles with those of the other set,

such contact being due either to bending of the latches themselves or to twist-ing of the needles in their guides so as to have the same effect. It will be evident, however, that when one set of the needles is projected While the other set is retracted, this objection is etiectually overcome.r

In Fig. 2' of the drawing, 13 represents the rojecting cam for the dial needles and 14 the retracting cam therefor, and in Fig. 8, 15 represents the draft cam for the cylinder needles which is so constructed as to permit rise of said cylinder needles When the loopaeceiving points are` raised, as in Fig. 4, further depression ot said needles v ing points 6 to the dial needles m should be eiected at such a point in the movement of the latter Y.needles that there is no likelihood of the trapping of the transferred loops by the closing latches of the dial needles.

j It desired, the loop-receiving portion of the point 6 `may he so high that the dial needle can pass beneath the same Without' any lift of the point, as shown in Fig. 9, in which case the points will simply have to be projected and retracted in their radial planes, the cylinder needles being drawn down in the first instance only far enough to cast their stitches and having further draft imparted to them after the loop -receiving points have been retracted and have cast their loops onto the dial needles, or on thc other hand, it the loop receivers are at one side of the dial needles, thc cams which impart radial reciprocating movement to the points 6 may be eliminated, rising and falling movement only being imparted to them by the arms 11 and 12.

In the modification shown in Fig. 10,v the loops are. formed over tixed loop receivers (ia disposed between the cylinder needles and alongside of thc dial needles, and at'tcr the latter have been projected so that their hooks have passed beyond. the loops, and their vstitches have cleared the latches, the needles arc raised at their outer ends so that their hooks will engage thc loops when thc needles are retracted. Such raising ot thc hooks of the dial needles may be effected by an angular pitch of the acting facesof the dial needle actuating cams, as shown in Fig. 10, and if desired each dial needle may have in the rear of its butt a tongue such as shown in Fig. 10, which tongue is subjected to pressure when the dial needles are tip ed and freed from pressure when said ial needles resume their normal horizontal position and the faces of the actuating cams again resume their normal vertical relation.

Various arrangements of cams may bc employed for imparting the desired movements to the loop-receiving points 6, such, for instance, as are shown in the Letters Patent of R. YV. Scott, No. 925,036, dated June 15, 1909, for imparting movement to the web-holders, and any desired means may be employed for imparting tension to the knitted Web, or causing the knocking over of the stitches upon the needles.
