Appncaanfna August 7, 1891. seatinqjmieve. (No modem A Be it known that-I, SATTERLEE ARNOLD, a

citizen of the United States, residing at Brook-l lyn, county ofKings, and Sate of 'New York, have invented certain new and useful .Improvements in Sewing-Machines; fully described and represented in the followingspecification and the accompanying drawings,

forming a part of the same."

This invention relates to sewing-1nachines, .and especially to'that class of machines in which lthe work is carried by a wheel provided with pins or points on which the work is iinpaled, the object of the invention being generally to improve the construction of this class of machines, and especially to provide a maf chine for uniting knit fabrics requiring less skill on the part of the attendant and by which the work shall be done more rapidly and with less labor and a close smooth seam-be secured without employing the slow and expensive process of registering-loops, as in tlie looping` or turningoff machines in common use for A uniting knit fabrics.

In'l carrying out. my invention l employ a large wheel provided Witiipins or points, upon which `the work is impaled and by which itis advanced, and I combine therewith an im` paler by which the work is automatically pressed O11 .the pins before the sea-m is made,

` it being necessary for the attendant therefore onlyto stretch the worl; upon-the impaling pins tothe desired tension and .secure it aty two points on the pin-wheel, the proper position of the work for sewing as the different partssuccessively approach the needle thus being assured wit-hout care on the part of the operator.` tVith-tliis pin-wheel and impaler l preferably combine a trimmer, by which the excess of material above the'l seam rey moved, preferably. after the seam is made, and- 'means` for uncurling the edges of vthe fabric, so as to automatically secure the proper position of the edges of the fabric for trimmingA and sewing. l provide also a rubber, scraper, or na-pper, by which the edges of the fabric are rubbed, so as to removeany loose material and raise vla. napuuponytlie edges, and. a sheaiger, by which tliejnapraisedby the .rub-rn ber isvtrimmed off, soas *topa/id informingfa srnoothernished seam.

erably rotated continuously, as fully pointed I out hereinafter, and certain constructions, in-

cluding such a continuously-rotating wheel, in combination withother features, form parts of the invention independently ofthe impaler, as Well as improved devices yforming parts of the machine embodying the generalfeatures of the invention in their preferred form.

With the pin-wheel and Leo-operatingde-l vices above described I may employa sewing mechanism-of any suitable form for uniting is evidentithat the wheel and co-op'erating devices may be applied to manyof the forms ofV such mechanism now in use. I prefer, how-v ever,.to use a sewing mechanism-of substan` ythefabrics without registry of the loops, as ,it-

tially the construction 'of my PatentvNo.`

378,6et5, dated February 28, 1888, in which the v needle-bar has a movement in the line of feed n when the needle isout of the work, so as to form a retrograde stitch. A

For a full understanding of my invention a 4 detailed description of a machine ofthe pre'- ferred form embodying the same1 will now be.

given, reference being had to the accompany'- ing drawings, forming apart of-.this specification, in \vhich,- I y V Figure l isa sectional front-elevation of the machine.

Referring 4to said drawings, themf'rameof the machine consists" of the bed-plate A, upon which is' mounted the overhanging frame B,

extending toward .the front of the machine,

where it is provided .with two'depending arms QD, the for'mersupporting the sewing mech- -anis'm'andftllfelatter the feeding or pinwheel and 'colo'perating' devices, which are located ing frame Bat such a distance from the-'bed-l plate'A as tolte ontsidefthelattemfso that the The parts towhich my 'inven'tion*especially relates will first' be described in detail The pin-wheel E consists of a large' .'whcelprefenI ably arranged horizontally and providedbn `its periphery-near the upper edgejwith fa 'sework may 'readily heplacedupon and lcarried ries. of -radial pins 1 0, extending preferably through. the whole or a large lpartof thecircumference ofz the wheel, these pins being set at' any suitable .distance apart, so as to hold -the fabrics't'obe united in'proper position,

'the rim-of the wheel thusforming a pinfplate by which the goods are carried. 'Thiswheel E is. carried by a vertical shaf t F, monntedin bearings in the arm.D and provided at its upper end with a wormwheel 1],.which meshes with a worm 12 carriedby the shaft- G, which` is mounted transverse-lyof lthe machine in bearimgrson the arm O D, this shaft being driven'from a'vertical shaftH through beveled gears 1.3,,the shaft H being inturu driven -by the-main` operating-shaft of the sewing mechanism IA through worm 1 4 and-worm gear "15." 1 "v The main operating-shaft K may be driven in any suitable manner, but islshown as op erated by a belt-and-pull'ey' connection from the main. driving-shaft K, mounted 4in the frame A at the rear of the machine..

-The connections between the driving-sl1aft and `pin-wheel are preferably constructed to be'broken at' will, so that the latter 'may be thrown out of operation.. Any suitable means may be provided for this purpose. I have shown a simple construction vin which the shaft G is carried by a slotted bar 16, sliding 'on the-.head of the machine and held in position'with the 'worm 1'2 in engagement with theI gear -lLby spring 17.. T-he plate 16 is movedagainst the tension ofthe-spring 17 to lthrowthe worm. and gear out Aof mesh by a pin 18, acting within the cam-slot 21, formed inthe plate 16,v said pin beingcarried on a vertical stud orshaft20, actuated bya hanf die 19.

For thel purpose of automatically pushing the'work onto the impaling-pins, so that it is held` firmly in proper position as itl ap-l proaches the needle, I provide an impaler,

which engages the wjork,"preferably upon` 'both sides of'the impalingf-pins, and forcesit upon and down to the base ofthe pins, so that it. is held in proper position for sewing. This impaleris preferably of the formshow xnconsisting of `a head 22,.,slotted so as to engage 4 cam-groove.

23, sliding in supports in the arm C and pivotally connected at itsfrear end to an arm 24 on a-vertical shaft'25,'inounted in bearings onv the rear side of the arm C, this shaft 25 beprovided with abowl or roller running'in the The impaler. is preferably provided with a curved or inclined guiding-sur- `face on the side from 'which the wot-kap,

proachestheimpaler, so that the work is properly deflected or guided and danger of its catching'as it passes the impaler is avoided. .As shown,l the impaler iscurvedon the oppositeside also; but-'this is not important.

. While I prefer to use an impaler moving to 4 by a reciprocating head, vas shown in Fig. l,

may be found satisfactory.'

A trimmer is preferably mounted above the wheel on'thejopposite side of the needle from the impaler, and 4is constructed as follows:

The trimmer proper consists'of two rotary' cutters 28 29, carried, respectively. by shafts '-3031, connected by gears 32, so that the shaft- 30 is driven from the shaft 31 and preferably at ahigher rate of speed, as shown, so as to make a drawcutj The shaft 31 is driven by means of a pulley 33 and belt 34 from a sleeve ,ing operatedby aGaIn-groove 26 in the upper tidejof: the Worm-gear 15' by a crank-arm 27,

.and from the pin-wheel a Stationary ilnpaler may be used, and 'it is evident that the form 9 of the impaler may be varied widely..v Thus,

35, mounted loosely on theI shaft Fof the wheel E, this sleeve beipg driven by any suit,- able means, preferably from the drivi ngshaft K-by a'pulley 36and belt 37,' as-sho'wn.'

The' rotary A cutters andv4 their operating mechanism maybe mounted in a' fixed position upon the frame'of vthe machine in--any suitable' manner as such cutters are commonly mounted; but, for apurpose presently to be described, I.pref.er. to mount them, as shown, in aswinging-bracke'tBS, carried by a sleeve 39 'on shaft Einside the sleeve 35,. previously described.A This swingingfbracket with the trimmer is-held in the proper posi. ytion by means 'of an. arm 40 on the arm D, provided withI a pin 41,' adapted to hold the latter in place, this arm 40 b'eing preferably made movableve'rtically upon the arm D by a slot and set-screw 42,-as-'s'ho'wnin Fig. 3, so' that the pin may b e withdrawn to release -the bracket; 38 and'allow vit to be swung .upon the s and releasing 'the bracket.: fIhe arm .4Q may.4

ft F. Anyzotherconstruction-,may be.` used,l owever, for the purpose ofisecurin'g be a strong spring-arm secured in a yfixed po-- sition on the arm D, but which may be sprung upward to release the pin when the bracket is to be moved.

The bracket 3S-,is supported outside the shaft F by a bowl or roller 43, moving freely upon a rib 44 upon the upperside of the pinwheel E,`this bowl 43 being preferably made adjustable by a bolt and set-nut 1, as' shown,

so that the vertical-position of the bracket and trimmer may be adjusted, as desired, to secure the trimming of the seam on the proper line. The shafts 30 3l and cutters 2S 29 may both be mounted in fixed bearings in the bracket 3S, as such cutters arecommonly mounted; but, for the purpose of adjusting Athe lap of the cutters to secure the proper action and compensate for wear I prefer the construction shown, in which the shaft 3l is mounted in a fixed bearing 45, secured to the bracket 38, and the shaft 30 is mounted iu a hearing 46,`adj ustable as follows: The bearing 46 is supported by an ear-47, carried therelby and adjustably securedto an ear 48, carried by the bearing 45. The adjustment is secured by a pivotal connection at each vend of the ears formed-by three screws, the upper screws 2 at each end beingl threaded in ear 47 and resting in recesses in the adjacent face of ear 48, so as to form pivots on which the bearing 46 swings rin a vertical plane, these pivot-screws being` preferably in line 1 with gears .32, so that the'meshing of the latter is not affected by the movement of bearing 4G. p The lower adjusting-screws 3 also are threaded in the ear47 at each ,end and rest on the surface of ear 48. The central adjusting-screws4, between screws 2 and 3, are tapped through and loose in ear 47 and threaded in ear 48. j

, By withdrawing screws 3 and tightening screws 4, or vice versa, the bearing 46 may be swung on pivots 2 and any desired adjustment of the'lap of the cutters secured. It

.is desirable also that a vertical adjustment should be provided by .whicbthe distance between the cutter-blades maybe varied, so as to secure the proper contactpressure. For this purpose I provide the means shown in detail in Figs. 7 and 13. y The `shaft 30 is mounted to slide through ythe bearing 46-aud The hub Vttof gea-r 32 carries two adjusting-screws 7v 7', which `are tapped through the hub 6 from opposite sides and,-

engage the upper andlower sides ofv grooves or recesses 8, these sides being beveled opy posite .directions to form cam-surfaces, where they are engaged by the screwsl7 -'The shaft and gear are held against upward movement during the operationof the cutters by',

the bla es, and the shaft is adjusted. vertically todpress the cutter-blades together and compensate for wearl by loosening the screws 7 and tighteniugthe screw 7. By reversing this-loosening the screw] and tightening ine screw 7the pressure .maybe decreased tud thus an exact adjustment obtained. l

The surplus material above the seam removed by the trimmer is thrown oft' by a shedder formed of twolplates 49 50, mounted just above the cutters 28.29 and extending in the line of movement of the pin-wheel and outward from its periphery. These plates 49 50 are secured to the ear 4S, previously described, by screws '9, as shown, or in any other suitable manner, so that the shedder may readily be removed. The plates 49 and 50 are extendedon rthe opposite Sides of the cutterblades, so as to form guides between which the edges of the fabrics are held as they pass t0 the cutters, these guides 99 100 forming au uncurling device by which the curling or turning over of the edges of the fabric above the seam is prevented and the proper presentation of the fabrics to the trimmer secured. An'uncurling device is preferably used in connection with-the impaler and sewing mech- `anism, and may be found'suflicient to prevent.

the curling atthe trimmerwithout the use of the guides 99 100, just described, this consisting, inthe construction shown, oi' a plate 101, placed edgewise j ust-above and parallel with the wheel, opposite to or a little behind the impaler, and lhaving an inclined surface operating to uncurl the edges as the fabrics approach the impaler and sewing mechanism.

As above stated, I prefer to place the trimmer in the position shownV in full'linesin' the y drawings, so as to'trim oif vthe surplus portion of the material after the seam is made; but, if preferred, the trimmer may be placed on the otherside of the needle and the surplus ICO material trimmed ed before the seam is made.

My improved trimmer mounted to swing concentrically with its driving-shaft is adapted to be used in either position, and for the purpose of securing it inadvance of the impaler I have shown an arm 5l, provided with a pin 52, similar to the arm 40 and pin 41, previously described.l the arm 5l being mounted upon the arm D by a slot-and-screw connection 42, as in the case of arm 40, but extending in the oppositedirection from arm 40, so 'as to hold the trimmer in position upon the opposite side of the needle. This arrangemeut of the trimmer is shown in dotted lines in Fig. 5. As it is necessary that vthe fabric be impaled upon the pins before trimming, the impaler is mounted in advanceof they trimmer, Vand when the trimmer is positioned as just described, so as totrim-before the seam is made, I may employ a' stationary impaler, as previously described, and mount it upon the trimmer-frame,l as shownin dotted lines inFig.5L` f When the trimmer is to be secured inv position in advance of the needle, the shedder 49 50 must be removed; but a shedder of simila'rform may be secured upon the oppositeend ofthe plate 43', so as to guide the surplus material 'outwardl from the pin-wheel, as shown- It .will beseen from the drawings that to swing ,the vtrimmer it is IIO necessary only toremove' the pin 4i, solas to ryelease the trimmer andpto remove the bracke `by'ltiihich the rubber and shearer and their op erating parts, to be described hereinafter, are daifried.

For the purpose ofrnbbing down the s eam, removing -the surplus material left by the trimmer-such as' any loosecut lo'ops of-'knit goods-and raising anap upon the edge of the united fabricsi pro'videa rubber, scraper, or napper, which consists, preferably, as shown, of two or more knife-blades,which are provided with'teeth ontheir under sides, which engage -the edges of the fabrics. The'knifeblades 5,3,forming the rubber, are carried by an arm 54 on .a shaft 55, mounted on screws' pivot bearings 56 in a bracket 57, carried. by the arm B and removably'secured thereto by screws 58, or in any other suitable manner.' The arrnft is preferably adjustable ou shaft 55, as shown, so as to secure theproper action oi'therubber. The shaft 55 is rocked by a.4 crank 59 and pitman 60 from acrank-disk 61, drive'ufromthe main driving-shaftK or other part ot the mechanism in any suitable manner. As shown, th'e disk forms a pulley and is driven by a' belt 62 from theshafb K.

MVhile I prefer to form the rubber of toothed blades, as shown, itis evident that its construction may be varied. Abrush of'any suitable construction or a iile maybe used with good results,- but this construction is' preferable both on account of the better result produced and the ease with which the toothed blades are kept in proper condition. The movement, also, may be varied and a notating'rubber em ployed,vvvhichv may be of any suitable form and operated by any of the means in common use with rotating brushes' in looping-machines, but the reciprocating rubber is preferred. l

The long'nap raised bythe rubber is preferablytrimmed off to form a smooth and in "ished-inner edgeof the seam, and for this purpose I provide a Shearer, which consists, in the formshown, of an oscillating blade 63, carried by the shaft 55, previously described, so as to oscillate with the rubber 53 and act upon the fabric just after the latter, this blade 63 (Jo-operating with astationary'blade 64, munted on the base-plate A.

Referring especially to Figs. 1, 3, 4, 5,'and 10, this sewing mechanism will now be described. The main operating-shaft I, previonslydescribed, is supported'in the upper part of the arm G,'and is provided at its inner end witha crank-disk 67, connected by' a'link 68, withone'of the cranks 69 of the crank-shaft 7.0, the'` other crank .71 of which4 is connected by means of a link 72 withthe upper end of the looper-rod 73, which carries at its lower end the looper by which the needle-thread is carried/around the stationary shuttle 74.' This construct-ion is substantially that of my Patents Nos. 331,006 and 331,007. The looperLrod is provided near its middle nut in any position towhi'ch it may be ad-V justed inthe bridge-piece 75, the head of the -stud beingslotte'd to permit its adjustment bya' screwdriver. The needle-bar 7 9 isreciprocated horizontally iu a verticallyswing 'ing frame 80, pivotedon center screws 81 in arm C, the needlebar being operated by means of the link-connected primary and secondary,operating-levers 82 83, which are actuated from an .eccentric on shaft I through pitiilau Si. The take-np consists of levers 85, operated from a' camgroove on the crankdisk y67 through a pitmanSG and rockshaft, provided with a crank-arm 87 having a bowl The presser-foot consists of a plate 8S, slotted for the needle, as usual, and carried by aspiring-bar S'J, mounted on the frame, so that the presser-foot is held in position outside of the pin-Wheel E and tion 'shown in'that patent, employing in com 4nection therewith,however,theimprovements -of my application, `SerialNo.v 318,646. filed l'co ITO

prefer .that shown.' A vertical shaft 90 isv mounted on the rear side of the arm C, adja- 'the thread are of a common constructiion cent to the shaft 25, and is oscillated'by means of a crank-arm 91, having a bowl running in a cam-groove on the lower side of the Worm-gear 15, all as shown in Figs. l, 2,'and 4. This shaftI 90 carries at its lower end a slotted roclg-armx92, in which a pitman 93 is adjustably\securedv by means of set-screw 94,' this pitman ,93 being secured at its oppositefend to `vthe needle-bar'frame 80 by a p ivoted ad- ]'ustable connection 95, as shown in Fig. rl0, so th-atvthe throw ofthe needle-bar frame may be varied by adjusting the pitman 93 in the slotted rock-arm 92 without changing the central position of the needle-bar frame. The

thread-pull and other, devices for controlling and need not be described.

The special form of voperatingmechanism,v

thedevices for guiding the looper-rod, and the connections for swinging the needle-bar frame form no part of the vpresent invention, but are of substantially the construction claimed in my application `above referred to.

Theoperation of the machine, so far-as it involves the features of my invention, will be understood from a brief description inv connection with the drawings, especially Fig. G.

f The fabrics to be united are placed upon the pin-wheel E by securing the advance end of the fabric to the pins slightly in advance of the impaler and then stretching the fabric to the desired tension and securingthe fabric to the pin-wheel' upon theopposite side of the wheel justin advance of the shedder G6, or at any point, desired, in'accordance 'with f vthelength of the fabric tobesewed. lf the -work consists in sewingl together knitandf4 woven fabric or fabrics o f different elasticity,

. as in securing the cuffs to the Lbody portions ofthe-fabrics andthen impalingfthemon some or all' of the pins suf-ciently to support the fabrics for sewing is assu-red. of a wheel having its` pins set quite closely of shirts and drawers, it isevident thatl both 4fabrics may beadju'sted as desired by stretchf/ ing them separately upon the pin-wheel, so',

as to secure the desired tension and relation them and hold them in place for the impaler, which presses lthem upon and downto the base of the pins as they are advanced-toit byA the pin-wheel, so that the proper position of By the use together, and preferably substantially as shown, l am able to properly support knit and other 'elastic fabrics and hold them in vproperv As before stated, the nee-` position throughout, so that the lines of sewing and trimming may be formed on' true right or curved lines, according to the manner in which they are placed upon the wheel, and the edges may be trimmed closely to form a fiat seam.' lf the pins fare placed wide apart, the fabrics will not be supported properly, but will sagbetween the pins, so that the lines of sewing and trimming will. be irregular when the fabrics are removed from the wheel. .The exact distance apart at which the pins are set will vary'somewhat with the character of the goodsbutwith the common knit goods it will be found that.l the best results are attained by setting the pins at a distance apart of from' a' sixth to a half inch, although this distance may be increased somewhat with fairly good results. In placing the fabrics upon the pin-'wheel no attion thus differing essentially from the ordinary loopingmachine, in which the points. are so arranged thatsuccessive loopsare impaled upon the points and the movement of the needle registers with the points, so that it. is necessary to provide different machines for fabrics of different, mesh. My vmachine Ais adapted tov sew fabrics of any mesh, the

range of adjustment of the stretch being unlimited, it beingnecessary only to secure the' ends ofthe fabric to the pins so that vthe fab-I i'ie will-be held in properfposition, andthe operatoris not required to impale the fabric upon each one of the pins in proper position for sewing, as this is automatically done by the impaler. proved machine, in which the fabrics are unit-ed bysewing withoutregistry of the loops insteadof by looping, I am ableto use with knit fabrics a feeding mechanism haw.

tention. need be paid V-to the stitch of the fabric in relation to thev pins, my construc-v It is evident that with my im:

ing a continuous moveinent,lwhich is impossible with looping-machines in which an intermittent movement is necessary. -ly -the use of` feeding mechanism havingthis continuous feeding movement I amenabled to place my punctu res m uch closer together than is possible with'an intermittent feeding mechganism, so that-the' number'of stitches niaybe IIC very largely increased, a feature ofgreat imzpartance in uniting knit-fabrics withoutreg# istry of the loops. l d placed upon the pins andg'the machine set-in operation, the work is fed -forward slowly by the pin-wheel, and vjust before the successive portions of the fabric relachthe needle they a'repressed inward to the base of the pins byl theimpaler, asshcwn in Fig'. 6so thatlthey. pass the needle secured in propervposition.

As the seam is formed and Athe fabric X fed forward past-the needle. The surplus material Y kabove the edge of the pin-wheel is trimmed off by, the cutters 2S 29, formin'gthe trimmer, and theshedder, formed of thepl'ates --LG 50, guides the surplus material fromt'he cylinder as it is trimmed olf, all this operatio'n being shown clearly in Fig. 6. After The work having been y passing the trimmer the edge of the united fabrics acted upon by the rubber, so as to knock on i: any lcose half or cut loops and nap up the ti 3er, the material being held in po- .sition during this operation by the curved guide G5. 'ihe operation of this rubber dif fers essentially from that of the brush now in common use in ioopinginachines`,in which the brush does notlact as a napper, because this is im pcssihle without risk of injuring the registeredv loop, the brush simply operating tc remcve the outside broken loop without affecting the fabric. In my machine, in which knit fabrics are united by sewing without regi try of the loops, as distinguished from The operation is the same with the trimmer adjusted to the opposite side of the needle and heldin position by the arm -inadvance of the needle or swung above the wheei to trim prior to sewing, the surplus material then being removed before the sea-m is made, the rubbingand shearing operations remaining the same.

The operation of the needle will be understood from a brief general description. The

stitches are set so closely together thatl the' vmovement of 'the work while theneedle is within the same is very slight, so that a continuous feeding movement is possible, even withgo'ods' of close mesh, and the stitch is forme'djand the fabrics secured together just abcve the pins withonn-fregistry of'the loops as he worl. is carried gast the needle by the pi v. wheel. Vtlith ne retrograde .sewing mechanism shown, in which'a seam is formed a combined open stitch and short gripntitch, as fully set forth inv my Patent No. 378,645, the work is carried past the needle by the pin-wheel to form v the open stitch. When the needle is withdrawn from the work at the completion of this stitch, the swinging needle-bar frame will be actuated by the connections heretofore described, so as to carry the needle a short distance in the direction of the feed, thus forming a short retrograde gripstitch, the needle then being returned to nor- 'mal position when withdrawn from the work and another open stitch being formed. The pinfwheel, in combination withthe retrograde movement sewing mechanism, provides a positive feed, and I am able to secure the proper function of the retrograde stitch and form a much closer seam than otherwise. I am thus able also to use the retrograde stitch with knit fabrics without employing a looping-cyl inder, and this -stitch serves to form astrong,

tight seam, irrespective of the line'on which Ithe knit fabrics are cui.

It will be seen that the pin-wheel is driven by the wormgear 11 and worm l2 by a slowmovcm'ent relatively to the sewing mechanism, and this form of feed enables the movement of the pin-wheel to be readily varied in the construction of the machine,.as desired, and a rslow speed attained without a. complicated gearing. y By means of the handle 19 and sliding plate- 10 the driving mechanism forthepin-wheel may readily and quickly be thrown out .of operation when desiredfor anypnrpose.

lt Wli be understood that I do uottliniit myself te thespecitic form of devices shown, as many modiiications'may be made therein without departing from my invention.

By the term ,radial pins in the specificaltion and claims ,Ido not mean that the pins must be set at right angles totheaxis or in radial'planes, but I'have-nsed this term to cover pins projecting outward from the periphery of -the `wheel, although not strictly radial. t y
