HENRY BRINTON, OF PHILADELPHIA, PENNSYLVANIA.

CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent NO. 700,730, dated May 27, 1902.

Application liled October 28, 1899. Serial No. 735,013. (No model.)

To all whom t may concern:

Be it known that I, HENRY BRINTON, a citizen ot' the United States, residing in the city and county of Philadelphia and State ofV Pennsylvania, have invented certain new and useful Improvements in Circular-Knitting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in that class of circular knitting machines wherein the cam-cylinder is provided with devices, termed pickers, for automatically elevating and depressing certain needles during the operations of Widening and narrowing the web, and wherein mechanism is employed for imparting the requisite continuous rotaryand reciprocating rotary motions to said cylinder at predetermined intervals, the continuous movement being effected during the production of tubular work-as, for example, the leg or foot of a stocking-and the reciprocating movement being had during the knitting of fashioned work-as, for example, the heel or toe of the stocking. In this class of machines during the knitting of tubular work the entire circular series of needles in the needlecylinder are in active position and are actuated by the revolving knitting-cams. Preparatory to the production of fashioned Work aboutone-half of the series are raised above the active path of said cams and the latter are reciprocated to and fro, the end needles of those remaining in action being lifted out ofA action in alternate succession until the requisite narrowing of the web has been accomplished, whereupon the said needles are depressed into action in inverse order to the last preceding operation, so as to effect a corresponding Widening of the web. This being done, all the needles are moved into action and the knitting of tubular work is resumed.

The leading features of my invention relate, first, to a novel clamp-support for the needlecylinder; secondly, to improved picker-controlling mechanism; thirdly, to cam devices for shifting the half-series of needles out of and into action, as desired; fourthly, to mechanism for automatically stopping and controlling the operation of the machine at certain stages of the knitting operation; iifthly, to

means forautomatically regulating the length of the stitches at predetermined intervals, and, iinally, to variousnovel features of construction and combinations of parts, which will be hereinafter particularly described and claimed. Q

In the drawings, Figure 1 is a plan of the machine. Fig. 2 is a rear elevation thereof. Fig. 2a is a detail of the link connection between the stitch regulating lever and the rock-shaft under the control of the pattern mechanism. Fig. 3 is an end View of the machine. Fig. 4 is a longitudinal vertical section on theline 4 4 of Fig. 1.

Fig. 16 is a similar detail of one of the elevatingpickers and a portion of the cam-cylinder, as `on the line 16 16 of Fig. 5. Fig.V 17 is a like detail of the rock-shaft for setting the pickercontrolling slides, as on the line 17 17 of Fig. 1.

1 designates the bed of the machine; 2, the

IOO

fixed needle-cylinder; 3, the rotatable camy cylinder, and 5 the driving-shaft, provided needle-cylinder lxedly.

with a bevel gear-wheel 6, which coacts with the lower toothed portion 7 `of the latter cylinder.

8 is a clamping-ring which supports the This ring is adjustably mounted on the bed-plate and has cer- -tain provisions, hereinafter recited, for vertical adjustment. The lower portion of the ring is fitted within the usual circular opening of the bed-plate, the projecting upper portion being split vertically, as at a, and horizontally, as at b, to afford two expansible jaws 9 9. Journaled in the lower'portion of the ring is a vertical shaft l2, which extends between the opposing edges of the two jaws, the interposed portion of the shaft being laterally flattened, as at 1S, throughout the length of the jaws to aord an elongated ectherethrough in a manner to be movable into and out of the paths of the needle-heels to act upon the latter and be acted upon thereby. In the present instance thel elevatingpickers each comprise a crank-lever 22, full crumed at the upper end of an arm 23, which is pivoted on the exterior of the cylinder. The lower arm of the crank-lever is provided with aslot 24, to which is fitted a pin or stud 25 on the Wall of the cylinder, While the upper arm of the lever is provided with a notched projection 26, which extends through a slot in the wall of the cam-cylinder, so as to lie immediately above the adjacent stitch-cam 27 and to be movable between the outer end of the latter and the opposing upper end of the central V-cam 28. A suitablydisposed torsional spring 29, secured at its respective ends to the cylinder and arm, tends normally to maintain the notched portion of the cranklever seated at the outer end of the stitchcam. When the lever is in Ithis position, the notch thereof lies in the track of the active needle-heels, so that in the rotation of the cylinder the first opposing needle-heel will be engaged by said lever and raised thereby above the path of the knitting-cams in the usual manner. The lever upon the disengagement of the needle therefrom drops yieldingly upon the heels of ther remaining active needles and rides thereon until it clears the latter, whereupon the leverassumes vits normal position in readiness for a succeeding action. The two elevating-pickers likewise act upon and are acted upon by the opposin g end needles in alternate succession until the requisite number of needles have been moved out of action.

The depressing-pickers each embody a partially-rotatable arm 30, slidingly mounted on a post 3l on the exterior of the cylinder and held in operative position by the `pressure of a spring 32 and by the coacting beveled walls of a slot 33 in the body of the cylinder. The slot 33 is preferably A-shaped, the apex thereof lying above the plane of the knitting-cams. The free end of the picker extends through the slot and is provided with a needle-engaging notch or recess 34C. This end of the picker is maintained normally-at the apex of the slot by means of the spring 32, which, encircling the post, bears against shoulders on the arm and post, respectively. When in this position, such end will engage the iirst opposed needle-heel in its path and shift it down into the path of the knitting-cams and thereupon release it, the picker then riding yieldingly against the under sidesof the heels of the remaining elevated needles, and finally escaping the latter at the end of the stroke and resuming-its previous position-in readiness for a succeeding action. Preparatory to the narrowing operation both depressing-pickers are set below the plane to be occupied by the heels of theiupthrown needles, so that such pickers will move idly below such heels. The two depressing-pickers are simultaneously moved into or out of action and likewise act upon and render active the opposing end needles of the inactive series in alternate succession. y,

On the external wall of the cam-cylinder are two oppositely-movable slides 34 34, which are constructed and arranged to coact with the respective sets of pickers to render them idle and active at predetermined intervals. These slides comprise two horizontally-movable plates or strips having pin-and-slot connections 35 with the cam-cylinder. They are disposed between the depressing-pickers and are connected by means of links 36 with a head 37 on one end of a horizontal rock-shaft 3S, which is mounted in a bearing at the base of the usual thread-guide post 3S, whereby ICO IIO

when said shaft is properly turned the slides with a lug 40, which depends below the plane of the upper arm of the adjacent picker-lever 22 in such manner that when the slide is retracted its lug will abut against said lever and raise it out of active position. The other slide is provided with a pivoted dog or latch 41, the forward or free end of which lies above the plane of the adjacent elevating-lever 22 when the latter is in active position, so that when the slide is retracted to permit the movement of the depressing-picker into active position said latch or dog will be set directly above the lever 22. A suitably disposed spring 42, secured to the slide and to thedog, maintains the latter yieldingly in place. Such movement of the slide is effected just before the last stroke of the cam-cylinder during the narrowing operation. Hence when the elevating-picker engages the last needle to be thrown out of action the nose of lever 22 in its upward movement will abut against such latch and raise it against the pressure of the spring, the nose thereupon clearing the latch, whichlatter,resuming its normal position,will prevent the return of said picker to action. (See Fig. 6.) The dog 41 is provided at its shorter end with a lip or stop 4l, which takes against the lower edge of the adjacent slide, and thereby prevents the dog from dropping. During the knitting of tubular work both slides are in retracted position, the elevatingpickers thus being maintained in the inactive condition and the depressing-pickers occupying their normal position. Preparatory to the narrowing operation the rock -shaft 38 is turned by hand to project the slides endwise from each other, and thereby free the pickers 2O to permit them to assume their active position and at the same time depress the pickers 2l into inactive position. stroke of the narrowing operation the rockshaft is turned in an opposite direction, so as to retract the slides and effect the reversal of the two sets of pickers, as above stated. The latter movement of the rock-shaft is automatically accomplished by means of a camhead 43, which is at the proper time moved into the path of a toe 44 on the end of a rockshaft through the instrumentality of pattern mechanism, which will be hereinafter described. This rock-shaft is provided with suitably-disposed studs 45 45, which are designed to abut against a portion of the post or bracket 38, and thus limit the throw of said shaft in either direction. The periphery of the shaft is also provided with two ilattened portions a: and y, against which is adapted to bear a spring-actuated stud 46, iitted in said post or bracket, whereby the shaft is temporarily locked in either position to which it may be set. In the present instance a iiat spring 46, which is affixed to said post or bracket, presses yieldingly against the lower end of the stud and maintains it normally in contact with the'rock-shaft. (See Fig. 17.)

47 48 are two oppositely inclined cams itted in close proximity to each other in diagonal slots in a plate 49, set in the Wall of the cam-cylinder. These cams are independently movable horizontally into and from the interior of the latter. During the knitting of tubular work both cams are retracted. Preparatory to the fashioning operation the cam 47 is projected into the cylinder in a Before the final` manner to act upon and raise out of action the half-series of needles above referred to. This being accomplished, the cam 47 is retracted. In the linal stroke of the cam-cylinder during the completion of the'fashioning operation the cam 48 is projected into the cylinder, so as to act upon and return to action the half-series of needles previously upthrown, whereupon the cam 48 is returned to its normal position. The

cams

47 and 48 each comprise a plate provided with an outwardlyprojecting stem 50, having a laterally-extending stud 5l, against which bears a retracting-spring 52, set in a socket in the plate. Fulcrumed on the plate at a point intermediate the stems of the two cams, so as to swing in a vertical plane, is a rocking head 53, which is provided on its inner side with two bevels or cam portions 54, against which bear the outer ends of the said stems insuch manner that when the head is in horizontal position both cams will be retracted, and that when it is rocked to the right or the left the corresponding cam will be projected into the cylinder by the action of the bevel against the opposing stem. The rocking head is provided with an extension 55, which affords a handle whereby it may be manipulated by the attendant so as to set the lifting-cam in action. It is also provided with an inclined lower edge 56, which is adapted during the rotation of the cam-cylinder to coact with an /\shaped cam-piece 57, fixed on the bed of the machine, and thereby shift the rocking head into .normal position. The head is also equipped with a depending tappet-arm 58, which is adapted at the completion of the fashioning operation to coact with a movable trip-lever 59 in a manner to shift the depressing-cam 48 into action. This-trip-lever is IOO carried by the arm of a rocking frame 60,'v

which is fulcrumed in lugs 6l on the bedplate, another arm 62 of said frame being extended adjacent to the pattern mechanism and adapted to be actuated thereby in a manner to move the trip-lever into action or permit it to become inactive, as hereinafter described.

Referring to the mechanism for automatically stopping and controlling the operation of the machine at certain stages of the knitting operation, 63 64 are two pattern-chains,

the former of which may be termed a legi and-foot chain andthe other a heel-andtoe chain. These chains are hung upon sprocket-wheels 65 65, which are *loosely mounted on a rock-shaft 66, having its bearings in the bed of the machine. On the hubs of said wheels are ratchet-WheelsA 67 67, engaged by two pawls 68 68, respectively, carried by a common arm 69, fixed on the rockshaft 66. This shaft is operatively connected with the swinging radius-bar 70,- hereinafter described, and continuously rocked thereby. In the present instance the rockshaft is provided at one end with a depending arm 7l, which is connected by means of IIO a link 72 with the bar 70. .A means is provided whereby the said pawls may be engaged -with and disengaged from their respective ratchet-wheels in alternate succession, so that with two vertical slides `76V 76, respectively,l

which are tted to guides 77, depending from the bed-plate. These slides are socketed, as at 78, for the reception of studs 79 on therespective arms of a centrally-pivoted rock-lever 80, whereby through the movement of said lever the slides may be movedin opposite directions to each other and the cranklevers be correspondingly actuated to eifect the action and inaction of the4 respectivev pawls. The pivot-stud 81 of this lever is prov vided with a crank 82,which is connected by means of a link 83 with anothercrank- 84 on a rock-shaft 85, extending below and at right angles to the main shaft. `This rock-shaft is pivotally connected by means of a lever86 to y a clutch member S7, splined on the main shaft, to the endthat when said clutch member is shifted either to the right or left the rock-shaft is partially turnedand the rock, lever 80 likewise actuated.Y

Sleeved on the main shaft are the usual fast, and loose pulleys 8S 89, respectively. There is also sleeved on said shaft a pinion 90, with, which coacts a sector 91, carried on the up. per end of the vertical radius-bar 70, that is pivoted at its lower end to the standard of the machine. This bar is longitudinallyslotted, as at 92, to receive vthe wrist-pin 93 of a crank-wheel 94, which is mounted on a sec. ondary shaft 95, journaled below the main shaft. The secondary shaft is provided with a spur-wheel 96, which gears with and is continuouslydriven by a pinion 97' on the sleeve4 of the fast pulley, thus effecting the oscilla. tion of the radius-bar and its sector, and the latter in turn reciprocating the pinion and sleeve with which it-is engaged. The clutch member is interposed between the sleeves,

respectively, so that it may be engaged with either of them at will. In the present instance the innerends of the sleeves are provided with socketedcollars 98 99, respectively, and the opposingfaces of the clutch member are provided IVwith .spring-actuated studs 100, which are adapted to register with the sockets in the collars when the clutch member is properly shifted. l

From the foregoing it will be seen that when the clutch is engaged ywiththe sleeve of the fast pulley the vdriving-shaft and, perforce,

Y the cam-,cylinder will be continuously rotated and that when the clutch is engaged withthe sleeve of the pinion 90 the said shaft, and therewith the cam-cylinder, will be reciprocated.

heel-and-toe chain. with a suitably-disposed projection 107, which yis designed at a,v predetermined interval to Bearing against one edge of .the lever 86,

yby whichthe clutch member is controlled, is

a spring-actuated rod: 101, that is slidingly fitted to'an orifice in ,thev standard, whereby the said lever is normally held by said rod in a position to engage the clutch member with the sleeve ofthe fast pulley. This lever is provided with a lateral stud or projection 102,

below which extends a vibratory latch-arm 103, provided with a suitably-located notch ,104, with which said stud or projection interlocks when the lever is shifted to engage the clutch member with the sleeve of the oscillating pinion 90, the latch-arm thereupon locking the lever 86 in place in opposition to the spring-rod. The latch-'arm is carried by a rock-frame 105 on the bed-plate, one member 106 of whichframe extends adjacentto the This chain is provided abut againstv the said member and lift the same, thus kdepressing thelatch-arm and free- ,ing the lever S6, whereupon said lever, with its connections, is thrown to its normal position by the action of they spring-pressed rod. When the fast pulley is clutched tothe -main shaft, as above described, the position of the rock-shaft is such that the pawl 68 for the legand-foot chain is in action, while the other pawl is idle, and when the pinion is clutched to the main shaft .the position of the rockvshaft 81 is reversed and likewise the respective pawls. l

108 is `the belt-shipper, by means of which the driving-belt is transferred from one pulley to the other, as desired. This shipper includes a horizontally-movable rod 109, which is suitably guided yin the standard of the machine. This rodis normally held in position to maintain the belt upon the loose pulley by the action of a spring 110, which, encircling the rod, bears against a collar 111 on the latter and against the standard. Pivoted to the block is one arm, v112, of a toggle-lever, the other-arm, 112% thereof being affixed to a forwardly-extending rock-shaft 113, which is 1 j ournaled in lugs on the side of the gear-case. ,The forward end of this shaft is provided with a handle 114, whereby preparatory to IOO IIO

the starting of the machine the shaft may be turned by the attendant to throw the shipper toward the fastpulley, against the compression ,of the spring, the toggle upon passing its center locking the shipper thus adj usted. Extending from the toggle-arm 112;L is a toe 115, the free end of which lies directly above a-boss or shoulder'll on the lower end of a vertically-movable rod 117, that is fitted in a' suitable guideway in the bed-plate, whereby `the toggle-lever is locked in the position shown to maintain the belt upon the fast pulley. On the upper end of this rod isalateral and raises the rod 117. The shoulder on the lower end of the latter thus lifts the opposing toe and trips the toggle lever, whereupon the shipper, resuming its normal position, transfers the belt from the fast to the loose pulley, and in consequence arrests the operation of the machine. This action takes place at the completion of the leg and the foot portions of the stocking. When the machine has been stopped, as just described, the attendant turns the rocking head 53 by hand to project the diagonal lifting-cam 47 into the cylinder, and likewise turns the rock-shaft 38 to shift the slides 84 in a manner to throw the depressing-pickers down out of action and release the other pickers, which latter in consequence drop yieldingly upon the heels of the needles. I-le then moves the clutch, (against the action of the spring-rod,) so as to release the fast pulley from and lock the pinion 90 to the main shaft. The cam-cylinder is thereby reciprocated. In one stroke the lifting-cam impinges against and raises out of action one-half of the series of needles, whereupon the beveled lower edge of the rocking head rides upon the stationary cam 57, and is thereby moved to eifect the retraction ofthelifting-cam. Whentheelevating-pickers reach the open space from which the needles have been raised, said pickers assume their active position, and hence during the succeeding strokes of the cam-cylinder the end needles in action are lifted above the path of the knitting-cams, as above described, until the requisite narrowing has been accomplished. Before the final stroke in the narrowing operation a suitably-located projection 120 on the pattern-chain 64 engages the rock-shaft 43 of the cam-head 43, and thereby moves the latter into the path of the toe 44 on the outer extremity of the rock-shaft 38 to eect the reversal of the two sets of pickers, as previously described. When the projection 120 escapes the shaft 43, the cam-head' resumes by gravity its normal or retracted position. The reciprocations of the cam-cylinder continue and the depressing-pickers act upon the previouslyl up-thrown needles to move them into action at the proper intervals and eect the requisite widening of the web.

When all these needles have been returned` to active position and the formation of the heel thereby completed, a projection 121 on a link of the moving pattern-chain 64 coacts with the arm 62 of the rocking frame 60, which carries the pivoted trip-lever 59, above referred to, thus raising the latter into the path of the depending tappet-arm 58 on the rocking head. Hence this arm during the stroke of the cam-cylinder abuts against the trip-lever and effects the movement of the rocking head sufficiently to project the depressing-cam 48 into the cylinder, which cam thereupon acts against and returns to action the half-series of idle needles. The entire circular series of needles are now in active position. The fixed cam 57 coacts with the beveled edge of the rocking head, as before, to return said head to a central or neutral position, in which case both diagonal cams are retracted. Vhen the projection 121 on the pattern-chain 64 escapes the frame 60, the latter and therewith the trip-lever resume by gravity their normal or inactive position, whereupon the projection 107 on the chain coacts with the frame 105, that carries the latch-arm 103, thus partially turning said frame and depressing the latch-arm in a manner to release the clutch-lever, whereupon the latter, resuming its normal position, disengages the clutch from the sleeve of the reciprocating pinion and engages it with the sleeve of the fast pulley. This being done, continuous circular knitting is carried on to form the foot of the stocking, at the completion of which the operation of the machine is automatically arrested, as before, and the picker-controlling.'mechanisms are actuated for the formation ot' the toe precisely as above described in regard to the formation of the heel. clutch is automatically unlatched by the action of the projection 107 on the patternchain G4 and rengaged with the sleeve of the fast pulley, thus proceeding with the knitting of a series of tubular courses vuntil the operation of the machine is arrested.

Provision is had for automatically regulating the length of the stitches at predetermined intervals--that is, in the formationl of the heel and toe the stitches are slightly longer than in the production of the leg. This is accomplished by making the needle-cylinder vertically adjustable iu respect to the camcylinder and providing a vertically-swinging lever 122 for eifecting the requisite adjustments. This leveris pivoted at one end thereof to a bar 123, depending from the bed of the machine, the opposite end of the lever resting on an arm 124 on the rock-shaft 85, with which the clutch is connected. The clamp 8, above described, which supports the needle-cylinder, is provided with a sleeve 126, which is slidingly itted to a depending post 127 on the bed-plate. The post projects below the sleeve and is screw-threaded for the reception of a nut or nuts 128, upon which the sleeve rests. By adjusting these nuts up or down the lowest position of the needlecylinder may be nicely regulated. The lower portion of the post is centrally perforated for the passage of a stud 129,' the upper end of which is connected with the sleeve by a transverse pin 130,which extends through aslot 101a in the post, the lower end of the stud resting upon a set-screw 131 in the body of the lever. By this construction it will be seen that when the clutch is shifted preparatory to reciprocating Work the arm 124 on the rock-shaft 85 will slightly raise the lever 122 and perforce the needle-cylinder, thus increasing the length of the stitches, and lthat when the Upon the completion of the toe the IOO IIO

clutch is returned'to its normal position for circular work the lever and needle-cylinde will resume their original position. l

As during the knitting of long hosiery it is` desirable that the length of the stitches in the calf and `upper portion of the leg be greater than that of the stitches in theankle portion,

I provide a supplemental mechanism whereby the stitch-regulating lever is raised for a proper period as follows: 132 is a rock-shaft mounted in brackets or lugs '133,'depending from the bed-plate. On one end of this shaft is pivoted an arm 134, provided with a deder side of the latter for the purpose of adj ustment. On theopposite end of the 'rockshaft is fixed a depending arm 140, Fig. 15, that lies adjacent to the leg and foot chain G3 in the path of a series of relatively arranged high links 141 on the latter, whereby at a given time the said arm is moved outward and so maintained fora proper period, thus partially turning the rock-shaft and slightly raising the stitch-regulatinglever. `When the links 141 escape the arm, the parts controlled thereby resume their normal position.

As a simple and efficient means to lock the clutch intermediate the sleeve of the rotary pinion and of the fast pulley, and thus permit the cam-cylinder to be idle even though the driving-belt be upon said pulley, I mount in suitable lugs 142 on the bed-plate a pin 143, which may be moved into and from the path of the clutch-lever 86. The pin is projected normally into such path by a spring 144, which, encircling the pin, bears against it shoulder 145 thereon and against one of the ugs. and the pin is furnished with a lsuitably-located stud 147, to the end that when the pin is retracted against the compression of the spring the stud thereon may be drawn through the slot and by a partial turn of the pin seated against the outer face of the lugin a manner toretain the pin temporarily retracted.
