ing of the invention, it being understood} chine, that the motion changing mechanism and f be termed the mam knitting cams. the pattern mechanism for controlling the 1 movements of the shaft which carries the f controlling cams are substantially the same 1 in construction as in the Hemphill machine.

In the present machine, however, the cam for controlling the change of motion is so shaped that the needle cylinder is reciprocated during the knitting of the foot of the .stocking as well as during the formation of the heel and toe.

In the machine shown the needles are mounted in vertical slots formed in a needle cylinder 1 which is secured to a plate 2 mounted in the bed plate 30f the machine, and provided with a beveled gear engaged by a beveled gear 1, through which rotary and reciprocatory movements are imparted to the needle cylinder. The cylinder 0 erating gear at is secured to a drive shaft 5, and rotary and reciprocatory movements are imparted to the drive shaft through motion changing mechanism of well known construction such as is embodied in the Hemphill machine. The needles are divided into two substantially semi'circular groups or series L and S, the needles L being provided with long butts, and the needles 8 with short butts, as is common in this class of machines. Between the two long butt needles at each end of the series L, short butt needles 8 s; are interposed. The needles 8 s and the end needles Z Z of the long butt series comprise the suture needles for connecting the fabric knit upon the two groups of needles in knitting the split foot.

The knitting cams are mounted upon a plate 6 secured to theupper end of a sliding bar .7 the vertical position of the plate being controlled by cams '8 carried on a cam shaft 9 and engaged by pins carried by the bar, one of which is shown at 10 in Fig. 1. The shaft 9 is an intermittently operated shaft which carries the various cams for controlling the movements of the needle cylinder, and for controlling the various devices for operating upon the needles. This cam shaft is operated by a pattern mecha nism'such as is used in the Hemphill machine orin various other circular knitting machines.

The cam carrying plate 6 carries two sets of knitting cams so arranged and controlled that both sets ofcams act upon all the needles during rotar knitting, one set of cams acts upon the s 10ft :butt needles during reciprocatory knitting, and the other set of cams is inactive during theformation of the. heel and toe, and is active upon the long butt needles during the continuation of reciprocatory knitting in forming the foot.

One set of knitting cams -corresponds in construction and arrangement to the knitting cams employed in the Hemphill maoperating with these cams. in knitting the heel and toe comprise lifting and depressing pickers corresponding in construction and operation to the lifting and depressing pickers of the Hemphill machine. "As shown in Fig. 4, the main knitting cams comprise the two stitch cams 11 and 12, the center switch cam 13, and the two elevating cams 14: and 15. The narrowing devices comprise lifting pickers 16 and 17 mounted upon inclined pivot pins carried "by the' block 18 on which the knitting cams are mounted, .and'held yieldingly in position above the stitch cams 11 and 12 by spring: 19 and 20. The depressing pickers 21 am" I) K n r .2 me pivotally supported upon a standard 23 secured to the base plate 3 of the ma chine, and are yieldingly forced upward by springs surrounding their pivots. The depressing pickers are moved into and out of active position by means of a plate 24 which is secured to a block 25 and overlies t pickers, as shown in Figs. 2 and 3. The block 25. is secured to the upper end of a rod 26 which is forced downward by a spring 27. The lower end of the rod rests upon one end of the lever 28, the other end ct: which is connected by a link 29 with a lever 30 (Fig. 1). The front end of thelever 30 rides upon a cam disk 31 secured to the cam shaft 9, and the "cam is constructed to raise and lower the rod 26 at properintervals to move the. depressing pickers into and out of active position. The guard cam 32. is arranged over the depressing pickers to return the needle butts into proper relation to the pickers in case they are lifted by the pickers during the back stroke of the needles over the pickers. The mode of operation of the pickers is the same as in the I-Iemphill machine, and will readily be understood by an; oneskilled in the art.

n addition tothe main knitting cams, the

cam plate 6 carries a second set of knitting i cams arranged on theplate diametrically opposite to the main knitting cams. These cams, which for convenience may he termed supplemental cams, comprise the stitch cams 33 and 34, the center switch cam 35, and the two elevating cams 36 and 37. The switch cam 35 is pivotall mounted upon a vertical pivot pin 38 ant is held normally in the center position by aleaf spring 39 engaging its rear end. This switch cam is moved by the engagement -of the. butts of the needles therewith against either the end of stitch cam 33 or the end of stitch cam 34, according to the direction in which the needle cylinderis moving. The stitch cams 33 and 84, and the switch cam 35 are mounted u on a block 40 mounted to slide radially on t e camcarrying plate 6, and guided ing and widening in the. formation off-the.

After the formation of the heelor toe, as

the case may be, reciprocatory movements of the needle cylinder are'continued during the knittingot' the foot, and at this time the long butt needlesai'c directed through the supplemental. knitting cams being elevated after they pass through these cams so that they are not acted upon by the main knitting cams, the main knitting, cams acting at this time upon the short butt needles as during the knitting of the heel or too.

' The devices for controlling the long butt needles during the knitting of the foot, so

that they will be acted upon by the supple-' mental knitting cams, and will not be acted upon by the main knitting oams, comprise two needle depressingcams 54 and 55' arranged to be moved radially inward into position. to eng age the butts of the needles inthe upper or inactive plane and direct them down into a lower plane two fixed del a pressing cams 56 (and 57 for completing the 'depression of certain of the needles d'epressedjloy the cams 54 and 55,"as ewill be more fully explained hereafter, and'aneedle elevating cam 58 arranged on the sideoi the supplemental knitting cams opposite to the'side'on which the needle elevatin 'cam the long butt needles only into the upper or '95 inactive plane.

in this position until the slide 63 is shifted to disengage the cam finger from the cam carrying-lever 61.

In the construction and arrangement shown the knitting. cams are so arranged that the needles, after they have been drawn 'down' by the kniijating 'cams to draw the loops, andhavebeenmoved up to cast off the previous forrnd loops, remain in position with tl e late of the needle still in Just before the knitting phint is 1 ched, the needle is raised to c ear'thei; atch from the loop. \Vhen the needles are-\"n the lower or active level, therefore, the latches of the needles are in the loops on the, ieedles. In the con struction and arrangeniient shown, also, the lifting pickers remain it both the narrowing andgwidening, and during the knitting of t-helfoot. This manner of manipulating the needles by the knitting cams and lifting pickers has an important bearing upon the manner in which the needles should be manipulated in passing from phe heel or toe, as the case may be, on to the oot.

It is important, for reasons which will be more fully explained hereafter, that neither of the short butt suture needles should openate to .knit during the first reverse stroke of the needle cylinder in going upon the heel, c the foot, or in the too is knit or convenience before knitting the foot.

This picker 1s in the form of a Lever pivoted at 74, so that it may move ertically. The pivot 74 isca-rried by a bleak 75 which is pivotally mounted'to swing 'a bput a vertical axis, so that the-picker may move horizontally as well as vertically. Vertical move-.

mentis imparted to-the .picker by a fixed cam 76, over which the picker rides as it is swung about the vertical pivot 77. A spring 78 tends to hold the picker in normal position where it is out of the path of the needle butts. Themarend of the'picker is arranged to be engaged by the inclined upper end 7 9 of a rod 80; the lower end of which is pivotally connected to a lever 81. The front end of the lever 81 is arranged to be engaged by a pin 82 carried by a, disk secured to the cam shaft 9. The pin 82 is so arranged that as the cam shaft 9 is rotated to cause the shifting of the motion changing clutch, the pin 82 acts against the endof the lever'81, raising the front end of the lever and immediately releasin it. When the lever 81 'is thus operated, tie rod 80 is depressed, so that'the inclined end-79 acts against the rear end of the picker 73, swinging said picker in a direction to move it from the position indicated in Fig. 5 to the position indicated in Fig. 6. "As the picker 1s swung about its.

ion

verticapivot 77, .it rides up over the cam 76, so that its lower inncr aendmpasses above the short needle butts, and as the inner end of the picker swings toward the right in Fig.

During the eontinued move" ment of. the needle cylinder the butt of the needle Z acts to swing the picker into the position indicated in Flg. 5,.the-spring 78 also. tending to return the picker to this .p'bsit'ion. The pickerv now remains in this inactive position until" the motion of the needle cylinder is changed from rotary to reciprocating, in passing from the leg to the heel of the succeeding stocking,

The machine is provided with a yarn changing mechanism-8T "arranged to deliver yarn-to the needles at the p oint where they are operated by the main' knitting earns. and operated tochan'ge the yarn in passing from the leg to the heel and after the con'ipletion of the toe. The latch ring8'8 also provided with a threadguide-SQ for feeding .yarnto the'needles at the point. where they are operated by. the 'su ipleinen-tal knitting .ca'ms.

Assuming that a split foot stockipg is to be knit, in which the leg and top of the foot are knit-from black yarn, and the heeL-toe a'ndbottom of the foot are to be knit from whitexyarn, .the operation-of the machine is as followsF-Duringthe knitting (it the leg of the stocking. black yarn is supplied to the needlesby the yarn changing device; and black yarn is-sup-pli'ed to the needles through Lthe'threa-d eye ,89.- Both theinain and sup plelnental' knitting came not upon the needlesQand two knitting waves are formed:

which follow each other about the needles,

so'thatat each rotation ofthe cam cylinder two courses of loops are knit, and thus the leg oft-he Sit eking is knit lllfhalf the'nunr ber of revolutions of the" needle cylinder which would he required if hnt a single yarn were fed to the needles, and a 'slnglc knitting; wave torined therein.

When the .heelis reached, the cam shaft 9 is given a. movement which shifts the motion changing clutcln carries the pin 82 .past the end of the lever 81. and brings the depression 31 in the cam 31 under the end of the lever 30. This n'iovement of the cam shaft through the connections heretofore described thus changes the motion of the needle cylinder, causes the needle elevating cam 42 to be raised. into position to detlectthelong butt needles up into the inactive plane, draws the depressing pickers 21 and 22 down out of active position. throws the pickcr.73 into the position indicated in Fig. 6, and shifts the block 40 radially outward so that the supplemental knitting cams are'out of the path of the butts of the short butt needles but are in position to act on the long butts wheirthelong butt needles are deflected dowii into the active plane. During the knitting of the heel (or t0e),.,l 1owcver,- the long butts remain in thefinactive plane and] pass above these cams. The yarn changing device is also operated at. thistime' to change the yarn, so that white yarn is delivered to the needles at the point where they are operated on bythe inainvknittingi cams. The shiftingoftlieparts occurs while the needle cylinder is moving in its forward direction c'. the direction of the arrow Figs. 4 and ll. During the completion of the movement of the needle cylinder in this direction,

the can! 42 raises the long needle butts into the inactive plane, and durin this forward movement of the needle cylinder the needle Z is the last needle to knit. with the hlael: yarn fed through the thread eye 89. During the 'formation of the heel the lilaelttln' ezul leading throue 'h the thread eye S9 therefore draws idly back and forth through the thread eye 89 as the needle cylinder reciprorates. being'laid about the needles as the needle 1 passesaway from the thread eye in either direction. and being drawn back through the threadeye as theneedle'l up: preaches thethread eye. The thread is held taut-during this time by a takeupof nsual construction. The purpose of, throwing the suture needle a up into theinactive series .on the first return stroke of the needle cylinder in forming the heel can best he 'explainedt at this point. If the needle 8 were allowed short butt needlespa'nd that .inder, the black needle Z to the thread eye 89 would lie across the needle 8 at tho'time this needle drew a to. knit on the return stroke of the'necdle cylthread leading from the needle Z during the knitting of the heel,

would leadfrom the necdle s', and when knitting; with the black thread was resumed in going from ther'heel onto the foot, the black thread would not be properly presented to the needle I, anda stitch would be dropped at this point, thus forminga hole and imperfection in the fabric. During the first return stroke of the needle cylinder, however, the short butt suture needle 8 is raised to the inactive series by the picker 73 in the inanncr heretofore described, so that the needle 8 is-the last needle to knit with the white yarnjim'riue this stroke of the needle cyliutlen and the blac yarn theretore leads from me needle Z during the knit-- line of the heel, and isv ro )erl n'esentcd to the needle when this needle is operated during, the formation ofv thvijlirst' course on the foot. During the knityfitg of the heel the lifting pickers operate to effect the narrowing, and a-tter the narrowing has been coiupletedthe 'a'mshaft 9 is given an advance movementto bring the concentric part of the cam 31 under the end of the lever 30. so that the depressing pickers 21 aud'QQ are moved up into active position. During the widening the depressing pickers act to move two needles down into the active series at each stroke of the needle cylinder, while the lifting pickers remain in action and move a single needle into the inactive series during each stroke ofthe needle cylinder.

' bring the can: (39

When the heel has been completed the cam shaft 9, is given an advance movementto under the end of the lever 09, and thus operate the slide, 63, which throws into operation the needle depressing cams 54: and At this time the needle cylinder is moving on its last forward stroke upon the heel, and the lifting, picker 16 lifts the needle 8 of the short butt series up into the inactive series. On ,the return stroke of the needle cylinder, which is the first reverse stroke of the cylinder on the foot, the lifting" picker 17 moves the needle 8 of the short buttseries up into the inactive series. During the first stroke of the needle cylinder in each direction onthe toot, therefore, the needles 8, s, a and s 'of the short utt series are in the' upper or inactive series with the long butt,- needles. It is for this reason that the depressing cams 54 and Share so arranged that they do not direct the needles" down into the lower plane of the the cams 56 and 57 are provided for-completing the down ward movement of the short butts into the lower active series. If the cams 54 and 55 directed the butts of the needles down into the plane of the active series, the latches of the needles 8 ands would be swung out by engagement-withthe loops'on the needles at the time that: these needles were passing all the needles which are in the upper inactive series down into a plane where the long be directed against the. stitch cams. but do not direct them down far enough to cause the latches to be acted upon by the loops on, the needles. The short butt needles 8, 8, s and a", which are deflected down by the cams 5t and 55 during the first strike of the needle cylinder in each direction when passing,

butts will strike the switch cam 35 and.

from the heel on to the foot, pass idlyby the supplemental cams. The cams 56 and 57 direct the butts of these needles down the plane of the butts of the short butt needles, so that they will pass under the lifting pickers l6 and 17 with the short butt needles,

and will pass through the main knitting cams. During the continued knitting of the foot the suture needles 8. s are raised by the lifting pic rcrs' l6 and 17 respectively, so that only the suture needle which is the last needle in the series to knit is actuated by the main knitting cams at each stroke of the,

needle cylinder. and these needles, which are raised by the lifting, pickers, are returned to the active series of short butt needles by the cams 54 and 55 and the supplemental depressing cams 56 and 57. After the foot has hem completed and the toe is to he formed, the cam shaft 9 is given an advance movement. carrying; the cam 69 fI'OmIIIIdGI the lever 69, and bringing the depression 31f on the cam 31. under the end of the level" 3% This causes the depressing pickers to be moved down into inactive position, whe're' they remain'during. the narrowing operation, and alsomoves the cams 5 and 55 back out of active position, so that the long butt needles are not directed through the supplemental knitting cams. ,At, the end of the narrowing, the widening cams are thrown into action by another advance movement of the cam shaft 9; After. thetoe has been completed, the cam shaft this advanced to cause a shifting of the motion reversing clutch, which changes the motion of the needle cylinder from reciprocating to rotary,

shifts the cams 42 and 43 inc the position indicated in Fig. 4., so that the cam43 returns the butts into of .all ,theneedle 13o lnitt needles during the 'relatgia'e forward a etive series to the lower or active plane. and
