srncrrroa'rron forming part of'Letters Patent no. dated Ap 1902.

Application tiled April 24, 1901'. Serial No, 57,303, (No mod l.) I

To aIZZ. whom it? may concern;

Be it known thatI, FRANK WI OOMB, a citizen of the United States, residing at Norristown, Montgomery county, Pennsylvania, have invented certain new and useful Imrprovements in Stop-Motions for Knitting- Machines, of which the following is aspecifi cation.

Myinvention relates to stop-motions for knitting-machines, and particularly to that form in which rotary bobbins are employed, though some of the featuresof improvement are applicable to otherstyles of machines. L

In some respects my present invention is an improvement upon that disclosed in application for Letters Patent of theUnited States filed by me November 2, 1900, No. 35,272, said improvement relating more particularly to the tripping mechanism of the stop-motion head.

My present invention includes other important features, as will be particularly pointed out hereinafter.

One of the chief features of this invention is a revoluble bobbin-stand made to revolve in unison with the revolutions of the machine without supporting the bobbins directly on the revolving parts of said machine.

It is Well understood that when the bobbinstand and the bobbins of yarn and overhead connections are attached directly to the spindle or revolving parts of the machine the unequal weight between the bobbins of yarn, of which some are partly empty, and the lack of perfect balance of the bobbin-stand and overhead connections causesobjectionable vi .brations and increased wear of the revolving parts of the knitting-machine, resulting frequently inimperfect knitting and rapid destruction of the Working parts. By my im proved construction astand or support is used to sustain all the weight of the bobbins, bobbin-stand, stop-motion, and connections and to give greater stability and steadiness to the revolving bobbins, stop-motion, and other parts. The rotation is governed'by the driving device, which is attached to the spindle or other moving part of the knitting-machine.

To avoid as much as possible any Wabbling of the bobbin-stand and the stop-motion, I

make the rotating plate of the stand preferably ot' a large diameter, and this also allows of inserting-thread-eyes for the passage of the yarn from the bobbins to the needles through the rotating plate well inside of the bearingsurfaces, the rotation of the revolving bobbin-stand carrying the thread eyes in the proper relation to the thread-carriers of the machine.

By my arrangement the. threads are carried down within the axis or bearing of the rotary bobbin-stand. i a In the drawings, Figure l is a side view of a knitting-head with my improvements in place. Fig. 2 is an enlarged View of the stopmotion head and upper structure. Fig. 3 is a plan view of the tripping mechanism of the knitting-head, some of the parts being broken away and some omitted. Fig. 4 is a detail side view of the connection between the stopmotion and the brake mechanism. Fig. 5 is a sectional plan View on the line 5 5 of Fig. l with the bobbins omitted. Fig. 6 is a detail view, partly in section and partly in elevation, of the supporting means for the rotary bobbin-stand and the connection between the same and the spindle of the knitting-head.

shoulder h on a fixed bracket t, which is supported'by the post 7c, fixed to the base-ring of the machine.- The ring f, which is adapted to rotate upon the shoulder h, is held in place by the gibm, screwed to the-bracket. The ring is rotated by a pin 41, depending therefrom and engaging 'a forked arm 0 of a collar p, fixed to the rotating spindle g, which is carried by the rotary head of the machine. A central standard 7' extends up from the rotary head Z2 of the bobbin-stand, and this car.-

ries at its upper part the stop-motion head I and attached devices. This stop-motion head comprises a casing 8, attached to the stand ard' to rotate-therewith and containing'the IOO tripping mechanism, to be hereinafter describecL' p The yarn from the bobbin passes first being shown at :23, Figs. 5 and 6.

through the threadgage t, thence through shearing devices a to feeler-iingers c, sweeps 20, eyes so, and thence to the needles through the hollow axis of the bobbin-stand, the guideeyes for directing the thread through said axis The threadgages, shears, and feeler-fingers, with their guide-fingers y, are all supported from the stop-motion head, as will be described.

The sweeps consist of wires having a semicircular bend at z, fitting over their pivotpins 1, which extend through the arms 2 of the block 3, secured to the reduced extension 4 of the standard 9', above mentioned.

The sweeps are held in by their bent portions engaging the upper wall of the arms 2. The inner ends of the sweeps engage the hooked ends of the rods 5, which extend down into the stop-motion head, so that their lower hooked ends may engage detent-levers 6, pivoted within the stop-motion head at 7, the lower arms of each of said detents engaging normally the shoulder 8, Fig. 8, of the movable shear-blade 9, which is pivoted at 10 and is under tension of the spring 11, tending constantly to close the shears and sever the yarn, which tendency is resisted by the detent. The rods 5 are held in proper position by the collar (Z, fixed to the standard, which collar affords a backing for the rods.

When the sweepis pulled down owing to the yarn becoming taut, the detent-lever will be withdrawn from the movable sheaublade, and the same will close under the action of its spring. The same result will be accomplished when the thread fails, for then the feeler-finger, which is pivoted to the stopmotion head at 12, will fall and its lower eccentric end 68 will engage the detect-lever and throw it out of connection with the shearblade. hen the shear-blade moves, a pin 13 thereon will operate the swinging lever 14-, which is pivoted centrally of the casing .5. This lever carries on its under side a pin or roller 15, Fig. 8, which will operate a springpressed detent 16, pivoted within the casing at 17, whereupon a catch-lever 1S, pivoted within the casing at 19, will be released. This catch-lever has a shoulder 20, adapted to hold a pin 21, which extends up through a slot 22 in the bottom of the casing from a trippinglever 23. This tripping-lever is pivotally supported on the standard by its hub 21, fitted to turn about the standard. The tailpiece 25 of this lever carries a catch-pin 26 rigidly, which extends downwardly therefrom and is normally engaged by a spring-pawl 28, pivoted in a slot 2.) of the block 30, which is fitted to slide on the standard and is attached to the hollow stem 31 of a tripping-foot 32, having a series of pins 33 extending down through the arms of the bobbin-stand. The said stem encircles the standard 0, and it and the tripping-foot are thus arranged centrally of the bobbin-stand and rotate therewith.

The tripper-lever 23 is under tension of a spring 3.4., encircling the standard, one end engaging a pin 35 of the lever and the other end being held by a collar 36, secured to the standard. A

It will now be understood that the release of the catch-lever 18, as described, when the shears operate will allow the pin 21 and the tripping-lever 23 free movement under the action of the tripping-spring 34, and the catch 26 will be withdrawn from the pawl 28, thus allowing the tripper-foot to fall by gravity to thrust the pins 33 downwardly, so that in the continued rotation of the bobbin-stand move with it, and in the final movement of,

the parts the roller 32 will return the lever to normal position by rolling along the cam-surface 14E of the lever 14, and thus through the pin 13 will reset the movable shear-blade 9 to its open position. In resetting the trip mechanism the pin 21 is moved, as will be hereinafter described, in a direction opposite to the arrow direction 21 and in this movement itstrikes the curved edge of the finger 63 of the catch-lever 18 and operates the same so that the catch-lever will be caught and held by the detent 16, and then the shoulder will have arrived in position to engage the pin, thus holding the trip mechanism in reset condition. The lever 14 is pivoted to a pin depending from a plate or bracket 1M within the casing s. The tripping mechanism, it will be seen, comprises the spring-pressed detent 16, which may be operated by the lever 1-4 with very little re sistance, as the pin 15 of the lever 1-1 is arranged near the pivotal point of the lever lei, and the catch-lever 18, which is made to rest against the detent 16 at one end, has a long lever-arm between the detent and its pivot 19 and a short lever-arm between the pivot and the point where the pressure of the main tripping-spring is sustained. The main tripping-spring being a strong. one it is desirable to avoid the pressure of the lever 18 against the detent 16 in order that the tripping of detent 16 may be'easily accomplished. The lever normally extends more nearly parallel with a line drawn through the pivotal points of detent 16- and lever 18 than at rightangles to it. Thepivot 31 is so located and the lever extends so that the pin 21 swings in an are which cuts a line drawn between the pivotal point of the lever 18 and the pivot of detent 16. The object of this is to relieve the pressure of lever 18 against detent 16, and, as will be readily seen,

if the locking-shoulder were at right antached to lever swings in an are more.

nearly parallel with the length of the lever 14, and as it rolls along the cam-surface 14 great power is exerted on this lever 14 to reset the shears and overcome the resistance of the spring which operates them. The lever 18 has a guardsurface 18, which effectually prevents the lever 18 from becoming locked with detent 16 while the pin 21 is at the opposite end of its travel frornthat shown in the drawings.

Referring now to the connections leading to the shipper devices, when the tripper-foot 32 falls the pins33, carried thereby, will be shipper-rod 49.

brought into the path of a finger 39, carried by an arm 40, fixed to a rock-shaft 41, journaled at its upper end in the standard 1, before described, and at its lower end in the base-plate 42 of the brake device, to which base plate the standard. is secured. The rock-shaft has fixed thereto an arm 43, which is connected by a link 44 with an arm 45, fixed to the rock-shaft 46, extending down through the fixed base-ring of the machine. This rockshaft has an arm 47, adapted to engage an incline 48 on the tripper-arm 49, which may be of any suitable construction to engage the The movement of the parts described will releasethe shipper-rod, which under the action of its spring 50 will operate the shipper-fork 51. tripper-foot and its stem being arranged centrally of the machine the bobbin-stand will not be'out of balance when rotated, as would be the case were some other form of device used located to one side of the center of the machine. These parts are carried around with the stand as the pins33 engagesaid stand, and these pins guide the trip-foot and its stem vertically.- For resetting the parts a handle is provided on the tripper lever at 37, by which it may be turnedagainst the tension of its spring and made to engage the catch-1ever 18, after which bysliding the tripper foot and its stem vertically the spring-pawl will engage the catch-pin26, and thus hold the tripper-foot up ready for another action.

In order to arrest the machine quicklywhen the power is thrown off, I employ a friction-. brake, comprising a brake-shoe 51, adapted when operated to engage the rotaryrflange 52 of the'knitting-head, Fig. 5. The head is carried by a shaft 51" under tension of a spring 51 in the base 42 and held inactive It will be seen thatthe by a latch-pin 53, engaged by a catch 54, se-' cured to the rock-shaft "41, so that when the shaft 41 is operated to shift the drivingmeans the catch-lever. 54 will release the latch-pin 53, and the shaft 51 being free to rotate under the action of its spring will apply the brake-shoe to the rotary base-fiange, the shaft having an eccentric end carrying the brakeshoe, as set forth in an application filed by me of even date herewith numbered 57,302.

. The arm of the stop-motion head directly above the shears is provided with a guide-eye 60, Fig. 3, to which a narrow slit 61 extends diagonally. This serves to hold the thread in position between the shear-blades.

The feeler-fingers a; are pivoted to the stopmotion head with a view to preventing centrifugal force from unduly afiecting them. They are arranged to fall in a direction opposite to that in which the head rotates, and they thereforeoperate transversely of .the stop-motion 1 head. By reason of this there will be no pressure on the'yarn due to centrifugal force exerted through the feelers, and the machine maybe run at any desired speed, and at the same time the feelers may be made sufficiently heavyto fall quickly when released.

- Thefeeler has a plurality of fingers65 extending in one direction'to pass into aplurality of openings formed in. the guides .or

guards, 66, and it has an upper and lower finger 67 extending in a direction at right 1 angles to the fingers 65 and at points above I and below the guide; This arrangement permits threading to be readily performed, while I preventing the thread from coming out when once'inserted.

p The feeler-finger is pivoted eccentrically, as. shown in Fig. 7, and in falling its eccentric portion 68 will operate the deten't."

The'guide-arm has a stop 69 for the upper I 'endof the feeler-finger to prevent its upper end from-springing out due to centrifugal force. c

I provide an improved form of knot-catcher,

IIO

Figs. 9 and 10, comprising two disks, having slots 7 0 extending inwardly from the edge and terminating in an eye 71. The disks are placed one over the other with the eyesin line, but with the slot in Oneinclining ina direction opposite to that in the other. The I 1 disks are spaced apart by a block or piece 72, 1

which leaves a space between them, and. in threading the yarnis passed through oneslot, then through the space between the disks, and through the other slot to theeyes; I

I The rods 5, controlled by the sweeps,'afre pressed by springs,'an d these are independently'adjustable by collars 73 on the standard, the lower collar having an opening through which'the spring for the upper'collar passes. It will be seen that the rotary bobbin-stand is supported axially over and inde- I pendent of the knitting-head, this feature making'it also independent of the spindle,

which is part ofthe knitting-head.

It will be understood, as before stated, that the rotary bobbin-stand and rotary stop-motion parts are supported independently of all the parts of the knitting-head, which parts include among them the spindle, as Well as any other parts of the head which would be affected by the unequal weight or irregular movement of the parts above.
