The knitting machine of the invention is conveniently housed in a carrying case 25 (Fig. 1) constructed of wood or some other substantial material and comprising a box-like cover 26 (Fig. 2) provided at either end with carrying straps 21 (Fig; 1) and a bottom or base board 28 removably fastened to the cover in any suitable way. j

The knitting mechanism is secured in place on base 28 between longitudinal beams 30 and lateral bars 3|, but before entering into a detailed description of said mechanism it is deemed desirable to describe first the role played by the cover 26 in the operation of the machine.

The longitudinal side walls of cover 26 are provided near their mid points each with a plurality of spaced pairs of screws; 32 (Figs. 1 and 2) which act to support a partition board 33 placed therebetween. At the'center of its upper edge partition 33 is provided with a pivot screw adapted to receivea turn table comprising a pair of sheet metal plates 34 (seev also. Fig. 3) connected together at their four corners by screws 35 in such manner that the plates-can be drawn together or spaced farther apart by manipulation of the screws. To prevent the turn table from flying off the pivot-screw, the latteris provided with a wing nut 36; Four'yarn receiving arms 3'! have their inner ends looped each about one of the screws 35, said. screws being tightened down tov hold arms 31 in place by the pressure of plates 34 thereon. At their outer ends arms 31 are suitably bent to support and guide a loop of yarn 38,said yarn passing from said loop througha guide member 40 removably mounted in one end of- -cover 26, and-over to' the knitting mechanism which is placed in close proximity thereto. There also may be provided a second guide member mounted in the other end of the cabinet but this latter member is'notshown.

The knitting mechanism is mounted on a base plate 4| 'secure'd on'baseboard 28 between beams 30 and bars 3| (Figs. 4 and 10) and its framing comprises a longitudinal center bar 42 connected at either end to lateral frame bars 43. The outer face of each bar 43 is provided with a pair of plates 44 (Figs. 4, and 11) which are secured to the bar by screws 45, said screws passing through slots 46 in the plates in order to make the latter adjustable laterally to vary the length of the stitches as, will becomeapparent hereinafter. Each plate is alsoprovided with a bearing notch 4! to receive one of the trunnions 48in the ends of a pair of rocking cross bars 50 to be more fully described hereinafter.

Mountedon I each plate 44 for fore andLaftLsliding movement thereon is a slide 5| having at one end an open end slot 52 (Fig. 11) adapted to receive theend' of trunnion 48, and at the. other endan .ean53 for manual manipulation of the slide. The slide is mounted on plate 44 by means of a screw- 54 in the latter playing in a slot 55 in the former, and can be moved to the position shown in Figs.- 5,""6 and -'7 where its' 'slot' -52embraces trunnion 48 and retains thelatter in notch 41 (Fig. 11), or to the position shown in Fig. 11 where slot 52 i's-free'of the trunniont'o-allow rocking cross bar 50" to be'removed fron rthemachine.

The outer longitudinal edg'eof 'ea'ch of the rocking bars- 50- hassecured thereto a backing strip 56 (Figs. 4 and 11') and'the inner portion of the upper edge of each Qfsaid b'ars has a'retaining strip 51 fastened thereon, the latter stripbeing of-suffioientl-y g'reater'weight' than the former to unbalance the bar and cause itsinner edge'to rock downward for reasons: t o b'ec'ome apparent hereinafter, however, it is desired that each of the'b'ars 50 rock only at certain'appropriate times; and to-' prevent its rocking at other times each bar 50 has a latchlever 58 pivoted to: its underside at 6!] (Figs. 4 and'8), said lever being urged by a spring 6| into engagement'with a lip 62 formed on the right-hand end (Fig. 4) frame bar 43 (s'ee also Figs; 5 and'7'). When it: is desired to rock either bar 50 the lever 58 associated therewith is moved fi'ee of'lip-tz and the bar allowed to rock by its own'unbalanced weight. Each of the rocking bars 50*"is provided with a long series of equispaced' rooves- 63' (Fig; 16) extending from backing'strip 56 to theinner'edge offlthe bar beneath retainingstrip' 51. Each of these grooves has slidably mounted therein a r hook member 64 (Figs. 9 and'l3l', said member being provided atits inner endwith a hook portion 65 and at its outer end with a restoring ear 66 extending laterally therefrom above bar '50. In the normal position of themembers 64' shown:- in Fig. 13 the outer end's thereof abuttlie-backing strips 55' and the hook's fifi' stand just forward of the retainingstrips 5T.

I'norder to prevent the oppositely disposed hooks 65 from sliding inward and banging against one another when the machine'is notin use, and also to move all of said hooks totheir advanced or to their restored positions simultaneously, there are provided two restoring bars- 61" (Fig. 14) which areplacedin contact-either with the restoring ears 65 orthe' outer edges of the hooking member as theoccasionxdemands', andia're drawn by hand to the desiredposition.

In order to restore advancedfhook;members"6 4 individuallyone after'the-other there is provided" ai plowc'am fia' (Fig; 12) :havi'n'ga shouldered lip l'fifto' engage one or'the. other-oi the retaining strips 51 (Fig. 17) alon'g' whichthecam ispulled by means of a handle IT,Jthe incline 12 of the em engaging the restoring" ears .66- of the hook;

4 members in succession and restoring them to normal position.

Midway between the hooks 65 is the center bar 42 which has a headed pin 13 projecting from its upper edge between each longitudinal pair of hooks 65 (Fig. The center bar 42 is also provided at each end with an eye screw 42 (Figs. 4 and 10) through one of which the yarn can be guided in its pathto the, knitting, mechanism, and on the other of which the free end of the yarn is' tied.

Mode of operation The first step ih'th'e preparation of the machine for knitting isto wind the yarn in a loop on arms 3T (Fig. 2), the free end of the yarn being passed through.guideF 'and over to the knitting mechanism where it is guided by one of the eye screws 42 and tied to the other. (Figs. 4 and 11) The next step is to lock the rocking barsv in their nor mal 'position by means of levers 58 (Figs. 4, 5 and 8), and to move" all of the hooking members 64 to their retracted positions (Fig. 11-) with the aid of restoringbars 61- (Fig. 14). The machine is then incondition to'commence knitting operations in' the manner now to be described.

In the following discussion it will be assumed for brevity and clarity of description and illustration that theiknitting operation is to be performed on a partially completed piece of knit goods '54 (Figs.- l5-22).

The piece of goods T4-is laid atop one of the bars 50 (Figs. 15 and 19) and the end loops '15 thereof slipped'over the headed pins 13'.

The first'step' of the operation consists intiIting the other (not the one on which the piece of Figs. 15 andIQ aridpiacing the anchored length of yarn 38 atop knit goods 1'4, adjacentthe pins of the'bars 61' (Fig. 14) allof the hook members 64 carried by the tilted hart!) (Fig. 15) and to rock the bar back to its horizontal position by means of the appropriate-lever 58-" (Fig. 8), thus bringing the hooksof =sam members into position to engage the length ofyarn 38 (Figs. 16

and 20).

The third step consists inengagingthe shouldered'lip litof-cam-EB with the retaining strip 5? and pulling said cam along said'strip to restore the advanced hook members 64 tonormal position (Figs. 17 and 21), the hooks 65 ofsaid members each pulling with it between the adjacent pinslB,

a section of the length of yarnB-B, whichby the and on to the sections'of yarn 38 previously pulled by hooks 65. "This, of course; forms" aseries of newen'd loop's 169 The tilted bar 50 is then rocked back to its norma horizontarposition andsteppne, above; repeated and so on.

goods was placed) bar-35?] downward as shown in- The secondstep is; to advance-by means of one point onward, however, is identical with that described above.

It is believed evident that the lengths of the loops 15, 16 can be varied simply by adjusting plates 44 (Fig. 5) laterally so as to vary the point to which the hooks 65 are restored with the sections of yarn 38. I

Referring to Figs. 23, 24 and 25, there is illustrated therein a simple modified form of the invention. This machine comprises a base plate88 upon which there is mounted between angle bars 8| and 82 a center board 83 having its upper edge rounded and studded with a series of equispaced headed pins 84. Center board 83 is embraced at either end by a sheet metal strap 85 which at its upper ends is suitably formed to provide bearings for two cylindrical bars 86 and 81. Each of the bars 86 and 8! is provided with a series of headed pins 88 having the same spacing as pins 84 but each being located midway between each pair of the latter. At diagonally disposed ends thebars 86 and 81 are prolonged past the bearing strips 85 to provide for their being manipulated by hand. Each of the bars 86 and 8! is maintained in its normal position with the pins 88 vertical by a stud 98 in its prolonged end engaging in an open end slot 9| in bearing strip 85, the stud being maintained in the slot by a compression spring 92 enclosed in the other bearingstrip 85 and pushing on the bar.

The operation of this device is substantially identical with that of the one described above, the end loops of the material being slipped over the center pins 84 and the bars 86 and 81 rocked by hand to advance and restore the pins 88 which act in the same manner as the hooks 55 hereinbefore described.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
