STRIPING MECHANISM FOR KNIFITTING MACHINES.

Application filed April 3. l922 -iierial 1 To. 549,253. Renewed July 8, 1924.

To all to hem it may con cern Be it known that we. KENNETH HOWIE and l VTLLTAH O. TAYLOR, citizens of the United States, andresidents of Norristown and Limerick. respectively, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Striping Mechanism for.

' Knitting Machines, of which the following is a specification.

The invention concerns acircular multiple feed striping knitting machine having its feeds distributed at separated points about the needle circle.

'lhc invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims. I

In the drawings 1 indicates a part of the head of a knitting machine. This is supported from a base ring 2 by frame parts, one of which is shown at 3, the machine being of the type in which the cam ring is fixed and the needle carrier rotates. 4 is the revolving take-up ring or plate, the take up mechanism. being omitted, as this forms no part of the presentinvention. The invention is shown in connection with a latch needle machine, though it will be understood that it is equally applicable to a spring beard needle knitting machine.

' There may be any desired number of feeds, for instance. eight. One of the yarn guides is shown at 5, there being one of these guides at each feed and it will be understood that these feeds are equally spaced about the knitting head. Any one or more of the feeds is rendered inoperative by retracting the .needle advancing cam at that feed, so that the needles will not be advanced to take new yarn, and shed their old loops below their latches, and hence no knitting will be done at this inoperative feed and the old loops will not be cast 011'. For retracting-the needle advancing came from operative position, there is a star Wheel 7 at each feed which is shifted into difierent substantially horizontal planes by a vertically movable support or bracket 8, Fig. 1

andFig. 10 so that the upper and lower arms 7, 7 of the star wheel will be located either in or out of the path of a contact member or dog 9 travelling with the knitting head Each star wheel 7 has two pairs of arms, one pair being in a higher plane than the other pair, and the arms of each pair are diametrically opposite eachother. The higher pair of arms are indicated at 7 and the lower pair at 7".

\Vhen'the bracket 8 is swung down the upper pair of arms will'be in the same hori, zontal plane with the travelling dog 9, and

' operative or inoperative upon the needles.

when the bracket 8 is swung to its upper limit the lower'pair of arms 7 will be in the plane of saiddog. -The star wheel is fixed to a shaft or body 7 rotatably mounted in the bracket 8 under frictional restraint of a spring pin 8 The lower end of the star wheel shaft'or barrel is provided with a recess or socket 7 receiving a cam member 6 consisting of a flat plate carried by a shaft or barrel 6*, rotatablymounted in a fixed,

bracket 6 secured to the fixed cam ring. A. detent 6 serves to prevent overthrow of the cam and star wheel when the latter is struck and turned by the dog9.

When the bracket 8 is depressed and the dog 9 strikes one of the high arms 7 of the star wheel, the cam 6 will be turned fiatwise to a lever 10, pivoted in the cam ring at 11 and this lever-will be free to swing outwardly away from the center of the machineand allow the needle raising cam a. to assume operative position. This cam is carried by an arm Z) pivoted at c to the cam ring and pressed by a spring 03 to operative position. The cam is swung outwardly into inoperative position as shown in Fig. 12 dotted lines when the cam 6 is turned so that its edge forces the lever 10 inwardly. This lever 10 operates a pin 6 which bears on the tail of the lever b carrying the needle advancmg cam.

The star wheel 7 remains coupled up with the cam 6 by means of the forked construction at 7 of its barrel, whether the bracket 8 be up or down and the arrangement is such that if the star wheel is struck by the dog 9 it will give a quarter turn to the cam 6 and this actingupon or relieving the lever 10, as the case may be, will shift the,

needle advancing cam in or out to make it The pivoted bracket 8 has an arm 8 extending up therefrom upon whose laterally extending upper end 8'a bell crank lever 14 bears, Figs. 1, 9 and 10. This bell crank lever is pivoted at 15 to thestationary sinker cam ring 16 of the knitting head.

The bell'crank lever 14 is operated by a rod 17 Figs. 1, 6, 8 and 9,.extending towards the vertical axis of the knitting head. The rod is guided at its inner end in a part of a support or track ring 18, Fig. 6, forming part of a central head, which ring is held in fixed relation to the knitting head by a post 19t-o which it is rigidly secured. This post is at the axial center of the knitting head, and it depends from a bracket or arm 20, ex-

tending up from the fixed base 21 of the knitting head.

In an eight feed machine, there will be eight of the radial rods 17 with their associated parts 6, 7, 8 and 14, together with the needle advancing cams, one for each feed.

The rods 17 are controlled as follows:

All oscillating ring 22, also forming a part of the central head, Figs. 6 and 8, is mounted on the fixed track ring 18. It is held. down and guided thereon by screws 18 held by the track ring 18 and having their heads overlapping the flange 22 of the oscillatory ring 22. This ring carries a series of devices to be selected by pattern mechanism and which in turn select connections for controlling the feeds, which devices in the example chosen to illustrate the invention consists of plates23 pivotally mounted at 24-, each having a dog or pawl 27. These traveling devices or plates are depressed by headed push pins 25, onefor each plate, said pins being slidably guided in a head 25 fixed on the depending rod 19. When any one of the pins 25 is pushed downwardly it will force the corresponding plate 23 down from an inclined position shown at the left of Fig. 6 to the substantially horizontal position shown at the right of said figure. The raised or inclined'position of the plates is the normal one. Each plate is pressed upwardly by a spring 23 and is stopped by The turning of the star wheel. which is I ,mounted by its. shaft 29 in the fixed track plate 18 and forms part of the power'transmitting connection leading to the feed and now to be described, will turn a cam 30 fixedly mounted on the lower end of its shaft 29. This cam bears upon a. pin 31 carried by an, arm 32 pivoted at 33 to the underside of the plate 18. The end of arm 32 has a projection 33' to bear on the inner end of the rod 17, so that whenthe' high part 30 of the cam 30 presses upon the pin 31 the arin 32 will be turned outwardly and the rod 17 will be moved radially outward, to cause the bell crank lever 14 to depress the arm or post 8 with pivoted bracket 8 against the tension of its spring 35 and the star wheel 7 will be lowered so that one of its upper arms will be in the path of the dog 9 carried by the rotating needle cylinder, and when the star wheel is turned in this lowered position the cam 6 will be turned to change the position of the needle advancing tion to operate the needles to knit.

This will efi'ect a change at this particular i the machine.

- the plate contacting therewith.

through a slot: 38 .in the fixed bracket or track ring 18, and carried by an arm 38,

will cause the projection 33 to recede from the rod 17and allow said rod to recede or move towards the axis of the head under pressure ofspring 35 which lifts the bracket 8 and causespost S to rock theibell crank lever 14. inwardly or towards the center of The lifting of the swinging bracket 8 will also elevate the star wheel 4 with the result that this particular feed will be changedagain (thrown out of operation) by the dog 9 operating upon the lower arm of the star wheel, which by the elevation of the star wheel, has been brought into the plane of travel of the dog. The cam 30 has depressions at its high and low. parts and the pin 31 of the pivoted arm 32 falls into these notches and actsas a detent to prevent the cam from overthrowing. All of the said arms. are under pressure of the spring band 34.

It will be seen that the step by step movement of the cam 30 operates the arm 32 to push the rod 17 radiall; outward or allows the arm to be retracted by the spring band 34 to allow the rod to move radially inward towards the center of the machine and at all times the arm acts to hold the cam 30 against overthrow.

One oscillation or back and forth movebent of the ring 22 takes place at each revolution of the knitting head and there- 'fore all of the pawl plates 23 perform aback and forth movement laterally in a horizontal plane for each revolution of the machine, and if any plate be depressed by its push pin, the companion star wheel 28 will be operated one step by the tooth of The member 22 is mechanically operated by a rod or rods 36, connected with a pin or pins 371 depending from the, oscillating ring .turnable about the post 19. The other ends of the rods are connected with an arm 39 fixed on a vertical rock shaft 40" suitably journalled in fixed frameparts and having an arm l-l fixed thereto at its lower end and extending under the take-up ring to be operated by a cam l2 secured by posts 4-3 to the. under side of the rotating takeup ring 4L. The oscillation of the ring 22 is comparatively short.

Itwill be seen from vthe above that the throwing in'or out of t is feeds results from the turning of the cams 30 which determines the positions of the-corresponding star wheels 7 up or down and that these star .whcels are operated by the travelling dog:

0 to change the position of tllB'OttIlTG and thus set the needle advancing cam a in or out.

Reverting to the adjustable needle advancing cam it will be understood that this rai 2s the needles to their upper limit for knit ig after they have been partly raised by the fixed cam indicated in dotted lines in Fig. 11. In other words if the cam (a is set in towards the vertical axis of the machine the needles after'being part ly raised by the fixed cam fshown in dotted lines, will be furl her advanced by travelling up and over the cam a and will then thus take the yarn and knit,"whereas if the cam a is set outwardly by the star wheel 7 and connections described, the needles will be raised only part way by the fixed cam but will pass the yarir feed u'i'hout taking the yarn, and this 'end ainst a plate held by a bracket 921-. h..e l to the cam ring 16.

For depressing the pawl plates 23 in any prescribed order to make the striped pattern, a jacquard mechanism is employed a spring clamp wire or loop 92. Fig. 9

0 )eratin mechanicall 1 and controllin the said plates by mechanical connections to the push-pins 25.

These connections include flexible or spring rods 44; lying in tubes 45) which ex tend from the central head or block 25 at different points around the same to a bracket 4:6 in which they are supported. These spring rods or flexible operating means are preferably provided by closely coiling a wire, that is,-it is like -a coiled spring with its coils closed one upon ianotherso that whllefit is free to accoir modate itself to the curves of-the tubes 45 it provides-a substantially longitudinal rigidity capable of transmitting power imposed thereon. There is one of these tubes with its flexible rod for each feed and one for a counter operating rod, and their ends .are arran ed'in line, side by side, in said bracket. 7

Push pins 25, one for each tube depend therefrom and rest upon bell crank levers 4:7 pivoted to the-bracket, so that when any one of the bell crank levers is operated it will push up the pin 25 resting thereon" 4 through the tube, depress the pushpin L5 at the other end of said tube and thus the corresponding pivoted plate 23 will be depressed to make its pawl 27 engage, and by its movement along its arcuate path, turn the appropriate stai wheel 28 and thus throw" in or out that particular feed to which this operated train of connections belong.

T he bell cranks 4'? are operated by rods 48 having-hooks to be engaged by slidable pawl arms 50 having hooks 51 to engage the hooks49. Formally the pawl arms 50 are in elevated position out of engage ment with the hooked rods 48 as shown in Fig. 3. They are mounted pivot-ally on an actuating rod 52 slidably guidedinthe fixed forks forming apart of the bracket 46, and they rest upon the heads at the upper ends of feeler fingers or pins slidably mounted in a carrier bar 55 supported by rods 56 slidablo vertically of the dependingtubular members 57 'ot the- .fixed bracket member 46.- This carrierbar with its fceler pins is pressed normally upward by a spring 58, Fig. 1, hereinafter mentioned.

The feeler pins or fingers are adapted, when permitted to do so, to pass down through openings in a fixed plate 60 Figs. 3, 4 and 5, of segmental form. They are lowered as a series by an arm 61 engaging a recess 62 in the carrier bar 55, and connected to a swinging frame 63 pivoted at 64 to the fixed bracket 46 and oscillated by an arm 65, Fig. 1 forming a part of the swinging frame, which arm is operated by a vertical rod 66, from a lever 67 pivoted in a bearing 68 on the fixed base ring 2. The pivot for this lever 67 consists of a shaft mounted in the bearing ()8 and having an arm 69, Fig. 2' provided with a roller 70 to be engaged by a cam rib or plate 71 mountediby arm 72 on therotary takeup ring.

A spring 58 presses upwardly against a tail extension 7 3 of the lever 69 and through the connections just described keeps the carrier 55 of the feeler fingers 54 elevated. But

when the cam rib 71, Figs. 1' and 13 of the.

rotary take up plate works under the roller 70, the carrier 55 with the feeler fingersare lowered and some or all of them will pass through the acquard member accord- This jacquard member consists of asheet of suitable material such .as heavystrong mg to the disposition of holes therein..

mental support 60 for the jacquard band is supported by the hubs of the discs or drum structure 7 4 and it is held against turning by an arm 74, Figs. 3, 4 and 5 held in the bracket 46 and having a forked end 74 engaging a pin on a depending arm 60 of said platforn i.

This jacquard drum is turned'step by step to feed the jacquard member as will be hereinafter described. The jacquard member passes-overthe perforated segmental lined plate 60 and if an opening or openings in the jacquard sheet registers with an opening in the segmental fixed plate the corresponding feeler pin or finger, when lowered by the'carrier bar 55, will go down through the registered openings'and conscqucntly the corresponding pawl arm 50, -wh1ch is resting onthis pin, will fall 1nto alignment with the hook of rod 48 and then as the pawl arm 50 sildes back (as hereinafter mentioned) it will pull upon the hooked rod 48, rock the corresponding bell crank 4. elevate its push pin 25* and through the spring rod 44 in the tube 45 the appropriate push pin 25 will be thrust down and the corresponding pawl plate 23 will be lowered, carrying its pawl or tooth into the plane of the. star wheel 28 belonging thereto so that upon the movement of the oscillating plate 22 the star wheel will be operated to throw the feed in or out as above described.

The backward movement of the pawl arms 50 takes place altogether and for doing this the actuating bar 52 is slid in its guideways by links 76 ccnuected with the upstanding arms GS of the rocking frame 63. This backward sliding movement takes place simultaneously with the depression of the feeler carrier bar 55, both movements being derived from the same connections i. e. rocking frame 63, arm 65 thereof and the connections back to the roller 70. The feeler carrier bar is lowered by the arm 61 attached to the rocking frame 63 as before described. Some lost motion of the pawl arms 50 takes place, however, before they operate the hooked rods 48 because the hooks of these pawl arms are somewhat in advance of the hooks of the rods 48, as shown in Fig. 3. p

If, however, any feeler finger or pin 54 strikes an imperforate part of the jacquard member which covers the hole in the segmental platform 60, it will be arrested while the-carrier bar 55 continues its downward stroke and this arrested feeler finger will hold up its particular pawl bar 50 which is resting thereon so that it will not engage the hooked rod 48 as it travels rear ward and consequently it will perform an feeler finger, leading to the pawl plate 23 will not be operated and thus this pawl plate willrema'iu elevated and will not operate its star WheelQ-S, when the niovementof the oscillating plate 22 takes place.

F or turning the jacquard drum a ratchet 77 is employed connected with the drum and engaged jbya pawl 78 pivoted at "('9 to an arm 79 pivoted at 80 to the bracket 4.6. This'depending arm has an adjustable stop screw 81"v to bear against the bracket 16.

working 'in the bracket.

The arm 79 above its pivot is borne upon by a horizontal rod 81 pivoted at 82', Figs. 1 and 2 to the bracket 46 and operated by a pin 83 on an arm 84 clamped by a. screw 85 to the vertical rock shaft 40, Fig. 2. The lever 79 bears upon a spring pin 86 When the rock shaft '40 is turned in the arrow direction Fig. 2 to give the member 22 a move- .ment in the direction of the arrow :11, for

turning'any one or a number-of the star wheels 28, that the pattern calls for,'the

. parts just described will be'operated to ad Vance the pawl 78 to engage afreslrtooth of th'ejacquard drum ratchet. w This stroke of the pawl 78 will be its idle one, the jacquard drum not. being turned on this movement, as it should not be, owing to the fact that the feeler fingers have been lowered and one or more of them has passed through the hole or holes in the jacquard sheet,'but on the reverse movement of the rock shaft 40 .the spring pin 86 will operate the lever "7 9 and the pawl 78 will be given its movement to turn theratchet and the jacquard member one' step, the feeler pins all being raised at this time.

As above stated the invent on canbe carried out in connection with a spring beard needle knitting machine, and for this pure pose substantially the same pattern mecha DlSIll would be used together. with the central head carrying the pawl plates ,23'and the connections leading from this head to the various feeds would be the same. The main-difi'erence over the present organiza.-' tion would be that instead of controlling the needle advancing cam from the rotation of. the star wheel 7, the needle presscr cam and shiftable yarn *vfingers would be controlled in a manner like that disclosed in our application for Letters Patent of the United States #409,265 filed September 9, i920, and 426,564 filed Nov. 26, 1920. I

It'will be understood further that the mechanismherein shown and described is illustrative'of one embodiment of our inven-tion and is not to be regarded as restrictive upon the invention the scope of which is defined by the appended claims.

It will be observed that we employ con trolling mechanism for the several feeds disposed coaxially of the knitting head and r comprising a mechanically operated memher, as 22 and power transmitting. devices as 23, carried by said travelling member 22 and that this controlling mechanlsm is in turn controlled bv the pattern mechanism,

aud'whiic the devices 23 are selected by the pattern mechanism they form as a group selecting mechanism in respect to the connections leading to the feeds, the whole group having travelling movement and the selection of the appropriate connection being due to the setting of the member 23 belonging thereto into line so as to contact therewith.
