KNI'rTrNe-MACHINE ATTACHMENT.

' Be it known that I, HORACE D. lncm'a i citizen of the United States, and a resident of the city of NewYorl'borough of Brooklyn, inthe county of Kings and State of NewYork, have'inven'ted a new and Improved Knit-t-ing-Machine Attachment, of

' lwhich the following is va full, clear, andrenfor different conditions, suchas lmittingplain or half-cardigan and-rackingstitches.'

act dcscription.- v i.

f This invention relates `to a new and' 1in v .provedattachment for'knitti'ng machines of `a type adapltedto knit sweaters, f whereby the speed t ereof may be'l varied to? allow In many. types of-sweaters, itis often de Vsii-able to. knit a band adjacent theflower `end thereof, of-a rac'king'stitch, while the' Vremainder has 'a'plain4 stitch, In suchan event, it has been found in practice that while knitting this racking stitch,the machinemust. be runV much slower'than is neces- Sary when'r knitting the plain Stitch; As

far as I amaware,`such machines as are now on theimarket run at 4the'slow-'speed at'all times, so' asfto accommodate the racking. stitch, and thus wastexconsiderable time,

I when they might be running fast while male ing the plain stitch. Inasmuch as the-plain sweater, a considerable capacity. is evident.

stitch is Jused 'in the greater part of the loss in time and chine, which will automatically shift from a fast speed while knitting the plain stitch, to a'slow speed while knitting the racking stitch, and also automatically shift vback' from aslow speedto a highspeed whenv `changing from the` racking stitch-to the plain stitch.

-A further object of this invention iis to provide a "device whichwill `be simple 'in construction, inexpensive to manufacture, strong, durable, readily accessible and adjustable, and automatic in` its operation.`

These and further objects, `together'with the construction and combination 'of parts, will be more fully described hereinafter and particularly set forth in the claims. Reference'is tobe had to the accompanyling vdrawings forminga part of this specifi.

A Referring more .particularly toy the separate parts ofy thisinvention as embodied inl I the form shownm the drawings, 1 indicates I the drivingshaft, which may'gbe driven in any suitable man ner from any suitable source of power, as forexample by being provided with a 'tight pulley 2 and a loose pulley' driven'bya shiftable belt. Onthe l -v shaft/1, there are iixed aplurality of gears 4- and 5 of different diameters and havin different numbers yof teeth,so as to afford a dierent driving ratio.' The gear 4, which i 1s shown as the largest, meshes with -a gear 6 loosely mounted on. ashaft 7.. '.lhe'gear` -5 meshes with -a gear 8,' which is also -loosely mounted on the shaft 7 and lseparate from -the gear 6. It will be seen that if the drivel l from the shaft l to the shaft 7 is through thelgears 4 and 6,- the shaft 7 will be driven atfa greater speed than if Iit werey driven is'slidingly mounted in a spline in the shaft i v7 and in a collar 107,-'secured Ato the shaft 7 by'a pin108. This key can be moved'to a position such that it will 'connect-either of the gears 6 and 8 vto the shaft 7, in vwhich position itwill rotate with. the collar 107 ina cavity, 10 formed' by facing cavities provided in the "opposed sides ofthe gears has groovesor recesses 1l and 12`communicat-ing therewith, whereby the'key can be locked toeither of the gears, thus vsecuring 85 through the gears 5 and 8. I'nor'der to I connect either of thegears '6 or 1,8 to the shaft 7, there is provided a key 9, whichv .6 and 8. Each of these cavities,'however, I

either of the gears to the shaft 7. VThe keyl 9 is connected by a 'rod '13, which extends ina groove" in the shaft 7, to a collar 14. The collar 14 is of the grooved type,and4 may be operatedin a manner to be-described. On the`shaft 7, ,there isprovided' a bevel gear 15, which meshes with a bevel gear 16 on a table 17.' This table is part of the 'knitting mechanism, and is rotated from the` The shaft 7 211,0v

shaft '7 by this connection. is alsop'rovided with a bevel gear'lS, which meshes with-a corresponding fbevelg'ea'r '.19

von" another part 20 of the knitting mechanism. The k-nitting mechanism is thus also operated from the shaft 7, and its speed depends on the speed of the shaft?.

It will be' readily understood by those skilled in the art that the .parts enumerated above are supported upon a suitable frame- Work; av part`of-this framework is shown in Fig. 1, and comprises a pair of standards a carrying alinedbearings .to receive the shaft 7. j '.lhe framework also,y includes an inner, bearing b, which supports the shaft 7 between the gears and 18; and the righthand standard a is provided with an extension c,- in which is formed a bearing c', to

lreceive one endof the shaft 1. c2 is a similar bea-ring in line with the bearing c and made rigid'with the framework by being connected to the standard c by means of an arm or bracket, or in any other convenient way.

,. The framework in question also supports 'a circular ring F, which surrounds the rotary table 17 and serves as asort of seat therefor, on Fig. 2.

As will be seen by reference to Fig. l, the

collar 14 ,is of the grooved type, providing means for the bifurcated end of a lever 21 to be operatively connected thereto, without vpreventing the rotation of the collar and the shaft relative to the lever. The lever maybe pivoted intermediate its ends at 22,

and is provided at its opposite ends witha pair of pins 23 and 24, Connected to the pm 23 in a slidingly pivoted manner, as by means of a slot 25, there is provided a connecting rod 26, which is connected at its opposite end by'a similar pin-and-slot connection, to anarm 2K7 of a-bell crank lever 28. `Connected to the-pin 24 by a slotted arrangement similar to that of the connection rod 26, there is provided a similar connect-r another, until such time as the key shall Acomevopposite'one of the grooves orrecesses 1 1- or 12 while moving in the 'cavity 10. The lost motion provided by the pin-and-slot connectionof the rods 26 and-29 to the lever y21 and the lever 28fallows for this action'.

vThere is also provided 'a spring'31, which is connected at its opposite` ends to therods 26 and 27. .A The length' of the vrods .26 and 29 may be adjusted in ,any suitable manner to the',proper degree, as by means of turnbuckles 32'and 33. l

'Oscillatabvly mounted adjacent to thel table 17 and projecting above the surface of the same, there is provided a' trip 3`4, hav- ,such as 41, in any suitable manner.

ing an arm 35 which projects horizontally at substantially right angles to the vertically-disposed body port1on of the trip. This trip may be operatively connected in any well known manner Ito the bell crank lever 28, as by being provided with an arm 36 at its'lower end, in which an opening 37 is provided, for the purpose of permitting a lug 38 on the bell crank lever 28 to have' operative connections with the trip 34 at vtrip 34 is formed with la groovedcollar 39,

in a groove of which extends one end of a lever 40, pivotally connected at any point, This lever is bifurcated alsoat its opposite end and extends into the groove o asimilar -collar 42 on a tri 43, which, similarly to the trip 34, exten s 1n a vertically-extending opening in the table 17, and is capable of vertical movement and oscillatory movement relative to the table. This trip 43 also has an arm 44,vvhich extends outwardly similarly to the arm 35. On the table 17, there fis provided a tripper 45, which is.shown in the form of a disk rotatably mounted on a stub shaft on the table,

and is adapted to engage eitherone of the4 arms 35 or 44 on the trips .34 and 43 respectively when the latter are on a level with the 'disk 45. By reason of the connection of the trips through the medium of the lever 40, however, it will be seen that when one of the trips is up, the other is down. Iii order that when one of the trips 34 or 43 is' rotated, or rather oscillated in one direction, the other tripwill be simultaneously rotated, and also in .order that when either one of the trips is oscillated, the bell crank lever 28 will be simultaneously oscillated, the 43 is provided with an arm 46 at its lower end, which is connected to the bell crank lever 28 at t-he same side of the pivot thereof as the lug 38, by means lof a link 47.. To afford a natural tendency of the trips 34, and 43 to occupy a normal relative position, there is provided a spring 48, which is connected to one side of the lever 40 at one end,`and to a fixed bracket 49 at its other end.

For the purpose of causing a vertical movement of the trips, one of the collars on one of them, such as the collar 39 on the trip 34,.is engaged by the end of a lever arm 50', Whichisrigidly connected to a' spindle 50',

mounted' on the framework of the mechatrolling mechanism` for the knitting mechanism, indicated at 52. This may be of any suitable character, such asan endless chain 53 having links of varying heights adapted to lift and permit the depression of a 'plurality of arms 54 which rest thereon. vThis chain may pass over a suitable sprocket wheel 64, which may be driven in any'suitable manner, so as'to be in synchronismiwith't-he knitting mechanism, as, for example, by means of a pawl and ratchet `connection with the table 17. vThe particular drive, however, does not form a part of this inventionT and -'any lwell known form may be used.

n. will be understood that the knitting mechanism comprises any well-known com- -fbination of mechanical elements by'means of which the needles are manipulated and controlled -in the manner required'to make plain and .racking stitches; .and these elements are the chain the lever l50 may be lifted to increase theyspeed at the Sametime when theA needles are caused to make the'plain stitches, and allowed to sink to reduced speed at'the same time when the needles are caused to make the coarsesor racking stitches. It will be seen that the control arm 51 forms, with y the lever 50, a bell crank lever, which will be' oscillated when the arm 54 is raised and lowered.

Inasmuch as the pattern chain 53 has links of .three dierent heights, and themedium height link moves the lever-arm the ,'de-v sired distance, it is necessary -to allow forthe highest link. For this ,purpose the lever 50 is broken at 150 into two parts, pivotallyconnected together and normally held in alinement by a spring 151. lThe overlapping portions of the lever 50 are prevented from moving too tar'relative to each other, bya pin and slot connection '152, indicated in Fig. .4. The collar 39 prevents the trip 34 lfrom going too high by engaging' a stop ormed' by the-support or frame in which the trip is mounted, which is-.allowedfor by the lever 50 breaking.

The operation of the device will be readilyl lunderstood when taken in connection with the above description. Assuming the parts in the position indicated in Figs.`1, 3 and 4, it will be seen that the trip 43 has `its arm` 44 projecting inwardly and at such a height that it will be engaged by the tripper 45, as it vcornes around,'with'the table 17 moving in the direction of the arrow .in Fig. 1. When this tripper 45 hits the trip v.43, as indicated in Fig. 4, it will swing thelatter outward; 1

`at the same time, through the connecting arms and links -46 and 47 will manipulate the bell cranktlever 2,8 vand swing thewarm 35 ofthe trip 34 inwardly,fs o as to be' position to loeoperated by the tripper 45 at some predetermined future time, dependin'gvon the controlling chain 53; which at that time will cause the trip arm 35 to be on a level with the tripper :disk 4 5.,t 'By throwing the trip 44 from tlieinward-lyprojecting position indicated in Fig. "1, the

bell crank lever 28 is roscillated towardthe left, thus pushing on the connectiligrod26 through the arm 27 and pushingon the connecting rod 29 through thearin 30. the key 9'should happen to Ivbe. in av position in oppositionto the groove'12, it would, by

this movement,through the instrumentality of the lever 21, and the rod 13, be drawn-into the groovel2, connecting-the gear 8in driving relation with the shaft 7. "If,vhowever,

the gear should be in a positionl 'such` that l Ithe key 9 was 'not -directly opposed-Tte the groove 12, vthe bell-crank lever 28, by pressl ing the rod Qr link. 26 to the. left, will tension the spring 31. It will, befnoted Vby reference to Fig. 1,- that the rod or-link 29 at this momentvis in positive engagement with the pin 24-on the lever 21, but the'pin carried by the arm 30 of the bell-crank lever v28 is at this time yin the eXtreme right endV ofthe s lot. In consequence, the rotationiof -the bell-crank lever-28 to the left, or in ay direction contrary to that of the hands of a clock, will not engage the rod 29 in Such a cess 12 opposite the key 9, the spring 31, which, as before statedis now undertension, will pull the rod 29.130 the'leftfalso, andthe rod 29 will then act on the pin 24, moving se .i

'100 way a-sto push it tothe left along'with the v rod, 26. The instant, however, that the gear -8 in the course of its rotationrbringsthe rethe upper end` of the lever 21l to the' right,

and thus draw the key 9 into'thelrecess1'2. This will of course lock the gear 8 to the vshaft 7.* It will thus be seen thatwhen the arm 44 on the trip 43was projecting invwardly, the drive from -.the shaft 1 to the shaft `7 was through the gear 4 and the gear 6, and that by this action of the tripper 45,

the drive has beenv shiftedto the inter-connecting gears 5 and 8 between theshafts 1 and 7, so that the speed of the shaft 7 has' been materially reduced Inasmuch as the vertical position of the arm 44 is controlled from the knitting mechanism control 52, including lthe chain' 53', this arm A44 will only be in position to be struck by theptripper 45 vwhenitis desired to change fromthe rapid drive of the knitting mechanism corresponding to v'the'closek'nitting of the sweater,'t the slow driveof the knitting mechanism corresponding to the coarse knitting of the sweater.. .v f p When 'the' machine changes froml a -slow drive of'the knitting mechanism, corresponding to the coarse knitting of the sweater, to the rapid d-iive, corresponding` to the close knitting f the sweater, another s part of the pattern chain will engage the arms 54 and cause the .lever50 to lift. As

. a result the'trip 35'which has been previously rotated in vtoward the circle of revolution of the tripper 45, will be lifted to the levelof this ti'ipper 45, and it will be of course engaged by the tripper 45, as soon as the tripper reaches it, to be rotated'outward or to the right, the saine as the trip 43 in the preceding case. When the trip 35 is thrown 5 outward in this way, the bell-crank leve-r will be rotated to the right.` The rod -29 will then be pulled, tensioning the spring 31'; and as soon as the recess 11 in the gear 6 comes opposite the key 9, the tension of 4this spring 31 will be sufficient to drawthe rod 26 to the right'also, swinging the lever j 21 to the left at its upper end, which-is contraryto its direction in the preceding case; and as a result the gear 6 will be locked with 25 the shaft 7, and the fast drive will once more come into operation. vIt will thus be seen that the knitting mechanism represented by the elements 17 and 20 will lbedriven fast .or slow, according to the type of stitch be ing knitted, and that the change from one to v the other will be' vautomatic and in synchronism with the change in the type of stitch.
