I., assignor to_ Hemphill Company, Central Falls, R. L, a cor poration of Massachusetts ‘ ‘ ' Application March 22, 1945, Serial No. 584.179 ‘ 6 Claims. 1 This invention relates to a new and useful improvement in fashion mechanisms of knitting machines for regulating loop length in various sections of the stocking such as the top, leg, etc., or within any of these sections. The mechanism shown is adapted for use in a circular independ ent needle knitting machine of the Banner type but the invention is not limited to machines of (01. 66-54) ‘ 2 . if desired, those of the leg fashioning mecha nism as well. As shown, it is associated with a single knitting cam‘ block, the idea being that so little space is occupied by it that separate de vices can be used for each cam block thus pro viding the shortest and best possible connections to each cam block and eliminating any prob ability of inaccurate response. The form of the invention shown herein is designed especially for this type or to circular knitting machines. It has been customary to vary the length of 10 a Banner type circular, independent needle, knit ting machine, as previously stated. the loops in various parts of a stocking to ob In the drawings: tain desired characteristics, accommodate yarns 1 Fig. 1 is a side elevation of a fashioning disc of different weight and secure a certain amount and the parts directly associated therewith; of shaping.

Patents #2,30'7,969 and #2,369,780 whereby the length of the loops knitted at one or more cam blocks is controlled. Fig. 3 is a detail view of a section of the edge of the fashion disc; Fig. 4 is a general side elevation of the fashion Fashion brackets of this kind occupy consider able space and are usually positioned close to a 20 disc, a knitting cam block and the connections therebetween; ‘ pattern drum on the main cam shaft by means Fig. 5 is a front elevation of the connections of which they are operated and where space is directly associated with the knitting cam block; at a premium. They have also been operated Fig. 6 is a top view of an adjusting screw where from an auxiliary cam shaft driven from the by a quick over all adjustment of stitch length 25 main cam shaft as shown in the Patent #2307, can be obtained; and 969 referred to but they are still rather bulky Fig. '7 is an enlarged view of one of the cams and difficult to install. Their bulkiness results of the fashion mechanism. of this invention show in the fact that they contain a considerable number of plungers side by side in parallel rela tion so that they may be engaged by an equiv alent number of cams in individual rows on the pattern drum. " Where a single fashion bracket has been used ing particularly the spherical contour of its cam 30 ming surface. As shown, the fashioning ‘mechanism consists of a disc I having a‘rim ‘2 and a hub 3 keyed to a shaft 4 which is the auxiliary cam shaft of the knitting machine. This shaft may be to regulate stitch length at both the main and auxiliary sides of the machine some difficulty 35 driven, if desired, from the main cam shaft by means of a train of gears such as that shown has been encountered in providing suitable con in Fig. 5 of Patent #2301969. Disc I is; recessed nections which will insure that both knitting cam on one side as shown in Fig. 3 to provide an an~ blocks respond accurately to the action of the ‘nular space between rim .2 and hub 3 for the fashion bracket. It is not practicable to use 40 reception of a renewable insert 5 of ?ber or other two fashion brackets of this sort, one for one suitable'material which is kept in place by any cam block and the other for the other because suitable means such as screws 6 passing through of space limitations. In addition, in such brack the'?ber disc and entering disc I. Preferably ets no means has been devised for making a quick over all adjustment or for indexing the 45 the edges of ?ber insert 5 are tapered a little as shown in Fig. 2 and the shape of its inner various adjustments so that they can be repeated face is such that all but its outer edge is spaced without experimentation. from the bottom of the recess. The reason for Fashion brackets of this type are generally this will be explained later. i ‘ used for obtaining the different stitch lengths Rim 2 of the fashion disc is provided with a required for major sections of a stocking. Pro gressive variation of stitch length in a given 50 plurality of radially positioned adjustable cams 1 by means of which the length‘of the loops knit section of the stocking such as in the leg by means at the cam block with which the fashion disc of‘ which it is fashioned or shaped have been is associated may be determined throughout the: secured by additional means. The invention of knitting of the stocking. Y this application is capable of performing all of the operations of the usual fashion bracket and, 55 Each cam ‘I is in the form of a machine screw £411,255 having a thick head 8 which is mounted on a ing the knitting of the leg or any other desired ' threaded stem 9 passing through a threaded open part Of the stocking. ing in the rim 2 of the fashion disc and into ?ber insert 5 as best shown in Fig. 2. The top II] of each cam is spherical, formed from a cen ter corresponding with that of the fashion disc so that every part of this top is equidistant from that center. Each cam is also pierced with one, or more holes II whereby it can be turned by a suitable wrench to screw it it in or out of rim 2 to vary its height. The purpose‘ of ?ber in sert 5 is to grip the stem 9 of each cam ‘I so . It is well known that the stitches produced by a knitting machine, when it is ?rst started and, ‘ particularly, if it is cold, vary appreciably from those obtained after it has warmed'up. There fore, the fabric produced'at one time is differ ent than that produced at another. The amount of adjustment required to compensate for this 10 can be ascertained but, obviously, it is not prac U! ticable to adjust all of cams ‘I repeatedly. With this invention this is unnecessary because a turn that it will retain such adjustments Without the of knob ll of lifter I3 in one direction or the assistance of lock nuts or other inconvenient de other will produce‘a corresponding change in vices. The disc is shaped as described above and 15 the height of cam block l9 for all of cams ‘I with as shown in Fig. 2 so that in case its grip upon stem 9 becomes insu?icient it can be distorted slightly by tightening up screws 6 so that it will bear more ?rmly against stem 9. out altering the indivdual adjustments of these cams. This adjustment of lifter I3 can be made ‘ very easily and as often as necessary without stopping the machine so that no loss in produc I The top of each cam 1 may also be provided 20 tion results. The same conditions are more than with an indicator I2 as shown in Fig‘. 3 to en able all of the cams to‘ be set in a given posi tion, if desired, and to assist in indicating the extent of small adjustments likely. to occur each day. Therefore, to enable the knitter to repeat the stitch length adjust merits, the top of knob II is preferably indexed, as diagrammatically indicated at 23 in Fig. 6, ‘Positioned directly above fashion disc I, so 25 so that he can set the cam block'at a glance that it is free to rest upon any cam 1 directly below it, is an adjustable lifter I3. The stem of this lifter is threaded through the end Id of an arm I5_ and also through a ?ber disc I6 held in to' the same setting each day and make the other subsequent adjustments in the same way." The fashion disc of this invention occupies very little space laterally of the machine so that much a fork in the end I4. The 'upper end of lifter 30 needed space formerly occupied by the fashion I3 is provided with a knurled knob H by means bracket is available for’ other uses. This also of which it can be screwed in or out. Fiber disc makes it practicable to use a separate fashion I6 serves the same purpose as ?ber insert 5, i. e., to hold lifter I3 in any of its adjusted posi disc for each cam block and to so position it that , the connections’between it and the cam block can tions. 35 be straight, rigid and short. All of these things ' As shown in Fig. 4, arm I5 is pivoted at a point are important to insure accurate re?ection at I8 adjacent the back of the machine. Knitting the knitting cams of ‘minute adjustments of the cam block I9 is mounted upon the usual plate fashion cams. Also the fashion disc of this in 2|] which" in turn is supported by. a ?at vertical vention is much less expensive and much simpler slide ‘2i, the lower end '22 of which rests upon 40 to make and to assemble than the usual fashion the top of arm I5 as shown. This point is more or less midway between the two ends of arm I5. By this arrangement a relatively large movement of? arm I5 is re?ected in a small movement of slide 2! and cam block I9 so that ?ne adjust merits of loop length can be secured by rela tively coarse adjustments of lifter I3. Asisllming that the knitting. machine is ca pable of 48 “moves,” fashion disc I is, preferably, provided ‘with 48 cams ‘I, one for each of these As will now be obvious, as one cam ‘l passesfrom under lifter I3 and is supplanted by bracket. ' Referring again to the indicator I2 on the top‘ of each cam ?, preferably these are made after the disc has been mounted on an arbor and all 45 of the cams ‘I adjusted to the same height meas ured from the center of the disc. If the threads on the stems of each cam ‘I are accurately cut and the indicators I2 are all made to point in the saline direction, all or any of the cams can be adjusted to a desired height simply by lining up the indicators I2.
