Fig. 11 is a sideelevation of the bracket projected from the side of the yoke, on which bracket the horizontal rod of the dial-needle presser is supported. .Fig. 12 is a perspective of the vertical-needle presser shown as detached. Fig. 13 is a perspective of a part of the cam of the cam-ring which operates the Fig. 14 shows in a diametrical section a modification of my invention in which the dial-wheel and dial needles are stationary, as well as the vertical-needle cylinder and vertical needles, with the can'i-ring operating the vertical needles revolving, as well as the cam-plate of the dial-needles. Fig. 15 is a view of the top of the diaLwheel of the modification, showing the recess for the gears, as well as the gears therein.
The several parts of the apparatus thus illustrated are designated by letter reference and the function of theparts is described as follows:
The letters S designate the driving-shaft, which is provided with a driving-pulley P and a shipper S The letter G designates a gear-wheel on the inner end of thedriving-shaft S, and this gear-wheel meshes into a geared rack g on the vertical-needle cylinder 0, by which as said shaftis rotated the cylinder 0 is caused to turn on the machine-bed B. I This verticalneedle cylinder 0 is vertically slotted to receive bearded or spring needles N, each of which is provided with an outwardly-projected nib H and these needles are as arranged adapted to be moved upwardly and at Fig. 1, and to descend by having their nibs n underrun the adjustable plate i as shown at Fig.

The letters 7c -desfigna'te cams formed on the edge of the cam-plate K, by which as the dial-wheel D revolves and .the cam-surfaces .6" engage with the ribs of the dial-needles the latter are forced outwardly in their .slotlted seats to hook onto the yarn, and then when coming in contact with the cam-surfaces the needles are drawn inwardly and when hooking into the yarn they cooperate with the vertical needles,.as will be hereina'fterdescri'bed.
"The letter B designates the sinker-bur, by which yarnas coming from the spools is by the sinker-bur carried -under the beards :of the vertical needles to form stitches when the needles arera'ised and innonnection with the dial-needles, as will be hereinafter described.
The letters A vdesignate 1a presser which is employed to force inwardly the :barbs 0r beards of the vertical needles N preparatory to casting off the stitches, .and this presser A is shown as attached to the :inachi-nezat Figs. 1, 2, and 5 and as detached therefrom at Fig. 12.
The letters A designate the presser employed to close up or force inwardly the beards or barbs of the dial-needles preparatory'to casting-oft the stitches, and-this presser is sleeved at its upper endontoa horizontal rod aiand made adjustable :t'hereat by meanso'f set-screwed uf. At its inner end thisrod'a tonguesinto a bracket-e7, projected from the yoke Y, and it is therein pivoted or hinged at a.
The letter u. designates .a rest for the rod a this 'rest 'bein g projected from theyoke Y, and on which rest the rod a? is supported.
The letter Z designates a depending leg which at its upper end adjustably connects with the horizontal rod e attheouter end of the latter beyond the connection made between the presser A and "the rod {4 This depending leg Z at its lower end is immediately over the projections or cams 011 the pattern-ring R v (indicated at 19.) hen either of the projections 19 comes in contact with the lower end of the leg l the latter is raised thereby and the dial-needle presser is raised from off the needles, so that a double or tuck stitch is formed, and these projections 17 are operated to thus act by the rotation of the pattern-ring R The letter 01 designates .a spring connecting at its upper end with the arm a and at its lower end with the base B, and the function of this spring is to make the descent of the presser A positive.
The letters E designate a ratchet-wheel which is arranged to turn with the shaft 6 on which it is mounted, and the letter E designates a sprocket-wheel arranged on and secured to said shafte so as to turn with the :latter.
The letter b -designa-tes apawl-arm which is provided with a pivoted pawl 17*, adapted to engage with the teeth of the ratchet-wheel.
The letter M designates a pattern-chain that is adapted to make a sprocket engage- .me-ntwiththe wheel E and be carried .around ithereon .as it is rotated by the ratchet-wheel.
The letters designate tappets or projections arrangednon therexterior face of thepattern chain.
The letter designates a vertical shaft which journals at a and is adapted to be moved upwardlyrand downwardlyin its journals, and when :moved upwardly to be so acvtuatedagainst the forceof the spring 6 encircling said shaft between the bed B and the e of the latteris extended inwardly and has secured thereon a crank-arm'bi 'w-hichis provided with a eameroller l)" -'on .its inner end.
The letters T designate the -,dow nwardlyextended .studs of the take-up-mechanism frame, which studs are supported bythe needle-cylinder andrevolve in a circle outsideof the web The letter T designates an arm which is .projected laterally from one of the studs of the take-up-mechanism frame, as shown at Fig. 1, and as this frame revolves and itsarm T andcam b =con1e into engagement with the roller-12 011the'crank-amn b of the pawl-shaftit operates said crank-arm to rotate the pawlshaftand thus actuate the pawl to move the ratchet-wheel one tooth.
The letter I designates another-arm which is projected laterally and outwardly from'one of the takeeup-f-rame studs T wh-ich may be the same :stud that :is provided with arm T as shown at 1, or another of the said studs, as shown in Fig. 5, and as the take-up frame revolves this arm I at each revolution will engage with one of the spokes m of the spoke-wheel m and so as to move it, the shaft 6 and the pinion p a quarter of a turn. As thus constructed, when one ofthe tappets on the pattern-chain has raised the shaft 6 the spoke-wheel will be in line with the arm 1 and when the pattern-chain has been stud U, on which the dial-wheel revolves. .This dial-wheel is rfiade with a hub 11*, that is downwardly projected from its under surface. to ita gear-wheel G which meshes into a gear-wheel G arranged on a verticalshaft having its bearingsin an offset formed on the collar 0 which latter is secured to the vertical stud U, on which the dial-wheel D and its hub turn. This vertical shaft g at its lower end has mounted thereon the gear-wheel G which meshes into another gear-wheel G turning upon the vertical stud U.
The letter O designates a plate which is attached to the under side of the gear-wheel G and the letters 0 O designate arms which are laterally and downwardly extended from said plate.
The letter O designates a nut which is threaded onto the lower end of the stud or shaft U, and O a washer thereon.
The letters L L designate arms inwardly extended from the studs of the take-up frame, and as thus constructed when the take-up frame is revolving and the arms L .engage with the arm 0 of the plate 0 the latter is rotated on the stud U and the gear G connected to this plate 0, communicates motion to the gear-wheel Gr on the lower end of the shaft 9 thereby causing the gear-wheel G to turn the gear-wheel G and the dialwheel D, the latter rotating in the same direction with the vertical-needle cylinder 0. The
,object of driving the dial-wheel from the plate 0 through these gears G G G and G instead of directly from plate 0 to the dialwheel, is that the latter combination and arrangement would be impracticable with the construction shown. The problem is to drive the dial-wheel from the cylinder,while leaving the casting-oif plates J stationary between them and not impeding the fabric. The only feasible way of effecting this is by gearing around the said casting-off plates and supporting the latter from a fixed central shaft on which the gears G G are free to turn, the fabric passing down, as shown, between the said casting-off plates and the cylinder. The
This hubhas arranged on and secured gears G G G2 afford asatisfactory means of transferring motion around the said casting-off plates without touching them, and the support of said casting-off platesby the fixed central shaft avoids all interference with the fabric, which would be a fatal objection to any attempt to support said plates from the outside of the machine.
The letters J J designate the casting-off plates, each of which at its lower end is connected to the plate 0 and is therefrom extended upwardly 011 an incline outwardly to pass up between the dial-wheel and the vertical-needle cylinder, said plate 0 being integral with projections from the stationary collar 0 Each of these plates J is provided upon its upper edge with a casting-off lip oredge Z and its operation in casting off the stitches will be described more fully in connection with the operation of the needles, the bursinker, and the pressers hereinafter.
Q In the modification-shownat 14 and .15 the needle cylinder C and the'dia-lew'heel Dfalld its needles do not revolve, but the cam-ring R and the cam-plate K and the casting-off plates revolve.
In the modification shown at Figs. 14 and 15 the gear-wheel G meshes into a rack 9 formed on the cam-ring R, instead of on the vertical-needle cylinder, as in the other drawings, and the yoke Y connects with the revolving cam-ring R to turn with the latter.
In the modification the'center stud or shaft U connects with the yoke Y to turn with it, and the dial-wheel D is made with a recess V, through which the stud U passes and where within said recess the stud U has mounted thereon the gear-wheel W which meshes into a gear-wheel W also arranged within said recess, said wheel V having a shaft 10 which is projected downwardly through the dial-wheel D and a vertical bearing to on the under side of the latter,
and on the lower end of this shaft 10 there is a gear-wheel W, arranged to mesh into a gear mounted on a sleeve 10 arranged 'to turn 011 the downwardly-extended hub 7t of the dial-wheel.
The letters a a designate arms laterally extended from the sleeve 20 ,011 whichare placed the casting-off plates J -.J each having the same construction as in the other figures and as revolving to have relatively the same position to the needles, the pressers, and their sinker-bur during the production of and casting off of the stitches as in the other illustrations.
The letter 92 designates a nut which is threaded onto the upper end of the vertical shaft orstud U and O a collar formed integrally with the lower end of said shaft or stud, and the function of this nut and collar is to keep the shaft U in position to be turned by and with the yoke Y The letter F designates a collar which encircles the lower end of the hub I2 below the sleeve 10 The hub 7r is made witha shoulder, against which the upper end of the said sleeve bears, with the lower end of the latter resting on the stationary collar F. The arms of the cast-off plates are projected up and outwardly from the sleeve 10 and the latter is rotated by the gears W WW, and IV, as before described.
The letter 2 designates a collar which is secured to the lower end of the hub 7L5 and is provided with arms 2 .2 which engage with arms L L, projected inwardly from the legs Z3 of the machine, by which engagement the hub 7L5 of the dial wheel is prevented from turning.
The operation of the mechanism thus illustrated and described is as follows: When the vertical needles are raised by their cams, as before described, yarn coming from a spool is by the sinker-bur B carried under their beards. The dial-needles are at the same time forced outwardly by their cam to pass between the vertical needles, so that the beards of the dial-needles are carried outwardly beyond the vertical needles, the latter having the yarn already under their beards, and when the vertical needles commence to draw downwardly by the action of their cam they draw the yarn over the dial-needle just back of the beards of the latter, and the vertical needles as drawing downwardly pass under the presser A, which presses inwardly their beards, so that the stitch passes over the latter as the vertical needles descend, carrying the yarn for a succeeding stitch through the loop on the vertical needles and casting off the old stitch over the verge of the cylinder, while the dial-needles having, as before described, had the yarn passed over them by the drawing down of the vertical needles are actuated by their cam to draw inwardly, carrying their beards over the yarn resting on their shanks, in which condition they pass under the presser A which closes their beards, so that the stitch thereon is carried outwardly over their beards as the dial-needles draw inwardly, with the stitch resting on the needles back of the outer end and in front of the beard, and while in this position as it comes in contact with the casting-off plate J its lip Z moves the stitch laterally from off the needles, and this operation is the same in the modification as in the other illustrations. By retaining the stitches on the dial-needles a short distance from their ends before being cast off the stitches are made shorter as to vertical length and have more length of loop laterally, by which the web has but little elasticity longitudinally, but is Very elastic laterally, which cannot be produced when latch-needles are used to produce like kinds of web.
I am aware that spring or bearded needles have been used in connected vertical and dial arrangement, and I make no broad claim thereto, my improvement consisting in the manner that I arrange them to be operated connectedly to shorten up the stitches vertically and elongate them laterally by the employment of a cast-oif mechanism operating upon the under side of the needles.
Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is-
1. In a rotary knitting-machine the combination of a cylinder provided with Verticallyarranged needles; cams whereby said cylinder-needles are caused to rise and descend; means by which the yarn is carried beneath the beards of said vertical needles when the latter are raised a presser whereby the beards of said cylinder-needles will be closed when descending to cast off their stitches; a dial- Wheel having radially-arranged needles and provided with cams whereby said dial-needles are forced outwardly and drawn inwardly; a presser whereby the beards of the dial-needles are closed when being drawn inwardly; and a casting-off plate adapted to engage with the under side of the dial-needles when the latter are being drawn inwardly and force the stitches therefrom, substantially as shown and described.
2. The combination with the vertical springneedles N, constructed to be operated sub stantially as described; of the sinker-bur B operated to deliver yarn to said vertical spring-needles; the presser A, operated to press in the beards of said vertical springneedles; the horizontally-arranged and radially-placed spring-needles N operated to be moved outwardly and inwardly substantially as described; the presser A and the castingoff plates J, J, each made with the edge or lip Z constructed to engage with the under side of said horizontally-arranged needles when the latter are drawn inwardly, substantially in the manner as and for the purposes set forth.
3. The combination with the dial-wheel D, having the downcast hub H of the vertical shaft or stud II, on which said dial-wheel journals; the gear-wheel G mounted to turn on the lower end of said shaft U, and provided with a plate 0, having downwardly and outwardly extended arms 0 0 adapted to engage with and be turned by the depending legs T of a revolving take-up mechanism; the shaft 9 having mounted upon its lower end the gear-wheel G adapted to mesh into the gear-wheel G and on its upper end the gear-wheel G and the gear-wheel G mounted on the dial-wheel hub, and adapted to mesh into the gear-wheel G substantially in the manner as and for the purposes set forth.
t. The combination with the dial-wheel D, having the downcast hub H carrying a gearwheel, of the stationary stud or shaft U; the gear-wheel G mounted to turn on the lower end of said shaft or stud; the plate 0 having the laterally extendedarms O O and secured to the lower side of said gear-Wheel G gears connecting said gear-wheel Giwith the gear-Wheel on the dial-wheel hub; a revolving take-up mechanism provided with inwardlyprojecting arms L L; a collar 0 secured to said stud or shaft U; and the cast-off plates J, J, upwardly projected from said collar substantially in the manner as and for the purposes set forth.
5. The combination with the cylinder 0, provided with a geared rack g and a drivingwheel G, of the shaft U, the dial-wheel D, having the downcast hub II, operated to be rotated substantially as described, of the col lar O connected to said shaft U, and the cast-off plates J, J, upwardly projected from said collar, constructed and arranged to be operated substantially in the manner as and for the purposes set forth.
6. The combination of the yoke with the presser A having a sleeved passage-way in its upper end of the rod o provided with the depending leg Z at its outer end, and at its inner end pivoted to the yoke; of the patternring R having the projection 13, on its upper surface; the vertical shaft 6 provided with the pinion P at its upper end, and having the encircling spring a the ratchet-wheel E; sprocket-wheel E pattern-chain M, having tappets t the pawl 17*, having the crank-arm I); and cam-roller 11*; a revolving take-up mechanism having the depending legs T T provided with the arm T and the arm 1 and the spoke-wheel m arranged on the shaft 6 constructed and arranged to operate substantially in the manner asand for the purposes set forth.
7. The combination with the stationary shaft or stud U of the dial-wheel D, having the hub II, downwardly projected from its under side, and provided with the gear-wheel G the gear-wheel G arranged to turn on said shaft U, at its lower end; the plate 0 connected to said gear-wheel G and provided with arms 0 0 adapted to engage with and be turned by the sides of a revolving take-up mechanism; and the gear-wheels G and G communicating motion from said gearwheel G to said gear-wheel G substantially in the manner as and for the purposes set forth.
Signed at Troy, New York, this 11th day of May, 1895, and in the presence of the two witnesses whose names are hereto written.
