  • the frame II is, as usual, provided adjacent its lower'end with an' 'arcuate' slot l3 to, receive a guide-stud l4, and is also pivotally connected by a screw II to one end of aneedle-bar vibrating pitman i 0.
  • the. pitmaniG- has a split strap -'l'
  • the eccentric I 8 there is secured to the cross-shaft 22 a gear-wheel 26 driven by a wormgear 21 carried by the needle-reciprocating shaft I. 1
  • the worm-gear 21 has a hub "extending into anannularly recessed collar 29 secured by screws 30'upon the shaft 5,
  • the -gear-.-hub 20 being preferably provided-with spanner-apertures v32 to receive, a suitable tool for 5 effecting adjustment of the worm-gear 21.
  • a loop-taker in the form of the usual rotary hook 34 having its axis of 'rotation substantially parallel to the cross-shaft 23, whereby the rotary hook beak rotates in a plane parallel to the plane of lateral vibration of the needle.
  • the rotary hook 34 is carried by a shaft 35 rotatably journaled in a bushing 35 secured in a lug 31 at the under side of the bed-plate I.
  • a bevelgear 38 Suitably secured to the hook-shaft 35 is a bevelgear 38 in mesh with a similar gear 39 carried by one end of a rotary hook actuating shaft 40.
  • the shaft 40 extends horizontally lengthwise of Y the bed-plate I and is ioumaled for rotation in a tubular feed-lift rock-shaft 4
  • the hook actuating shaft 40 carries a pulley 44 connected by a clipslots provided in a throat-plate 48, secured upon the bed-plate I and having the usual needle-slot 49.
  • the feed-dog 41 is carried by a feed-bar 50 having a slot 5
  • a crank-arm 55 Secured upon said feed-lift rock-shaft 4
  • the pitman 51 extends upwardly within the arm-standard 2 and has, at its upper end, a strap embracing a feed-lift eccentric 58 carried by the actuating shaft 5. It will therefore be understood that the feed-dog 41 is raised and lowered once for each reciprocation of the needle.
  • the rearward end of the. feed-bar 50 is pivotally supported by and between the upstanding arms 59 at one end of a feed-advance rock-shaft 50, disposed in substantial parallelism with the feed-lift rock-shaft 4
  • Clamped upon the opposite end of the feed-advance rock-shaft 50 is a depending crank-arm 53 connected by a pivot-bolt 54 to one end of a link 55, of which the opposite end is connected by a pivot-bolt 55 to a slide-block 51.
  • the slideblock 51 is shiftably disposed in a segmental guideway 58 provided in a rocking-member 59 having a fulcrum-pin 10 extending laterally from said member substantially medianly between the ends thereof.
  • the fulcrum-pin 10 is journaled for rocking movements in an apertured boss 1
  • the rocking-member 59 has an car 14 to which is pivotally secured, by a screw 15, the lower end of a pitman 15. At its upper end, the pitman 15 has a strap embracing an adjustable feedadvance eccentric 11 carried by the needle-reciprocating shaft 5.
  • the adjustable eccentric 11 is constructed, in the present case, substantially 2,218,096 lateral vibration of the needle or, in other words,
  • the slide-block carrying link 55 is connected by a ball-joint 18 to the lower end of a link 19 reciprocating endwise within the arm-standard 2.
  • the link 19 is connected by a ball-joint to an arm 8
  • , 82 is pivotally connected to the lower end of a pitman 84 having a strap 85 embracing a feed-controlling eccentric 85. As illustrated more particularly in Fig.
  • the eccentric 85 is secured by a set-screw 81 upon a shouldered crossshaft 88 journaled at its rearward end in a bushing 89 suitably fixed in an aperture in the rear wall of the bracket-arm 3, the cross-shaft 88 being disposed above the needle-reciprocating shaft 5 and in substantial parallelism with the cross-shaft 23.
  • the forward reduced portion of the cross-shaft 88 is journaled in a shaft-sleeve 90 which is itself journaled for rotation in a bearing-bushing 9
  • the spiral gear preferably has its side face annularly recessed adjacent the feedcontrolling eccentric 85 to receive a disk-flange 95 of said eccentric.
  • the shaft-sleeve 90 has a disk-flange 91 preferably having a beveled indexed periphery and provided with a series of apertures 98.
  • Adapted to releasably enter any one of said apertures 98 is a coupling-pin 99 extending from a side face of a coupling-disk I00 secured by a key IOI upon the shaft 88 for rotation therewith, but permitting limited movement of the coupling-disk I00 endwise of said shaft.
  • the coupling-disk I00 has a knurled head I02 centrally apertured to receive the head I 03 of a screw threaded into the forward end of the cross-shaft 88, the screw-head I03 serving as an abutment for a spring I04 which functions to hold the coupling-disk I00 yieldingly in contact with the disk-flange 91, with the coupling-pin 99 disposed in one of the disk-flange apertures 98.
  • the cross-shaft 88 may be turned to change the timing of the eccentric 85, as will be self-evident.
  • An angular cover-plate I05 is detachably secured upon the bracketearm 3 and provides for access to the mechanism within the bracket-arm.
  • fagoting comprises successive repetitions of a six-stitch figure, (1) a stitch a, made by vibrating the needle l8 laterally in one direction while the work is fed backwardly; (2) a succeeding and longer stitch 12 made by further vibrating the needle laterally in the same direction while the work is fed forwardly; (3) a succeeding stitch c of substantially the same length tially the same length as stitch a, made by completing the return vibration of the needle while the work is again fed forwardly. From this description, it will be understood that, in producing fagoting, the work is fed twice forwardly and once backwardly in each direction of lateral movementof the needle I8.
  • the needle vibrations are derived from an eccentric and the requisite workfeeding movements of the feed-dog are likewise controlled by an eccentric. While it has been old in the art to employ an eccentric for vibrating a needle-bar laterally so that the needle reciprocated once in each direction of lateral movement thereof, the present eccentric arrangement provides for so vibrating the needle laterally that the needle reciprocates a plurality of times in each direction-of lateral move-' ment thereof, and still further provides for the production of stitches of unequal lengths in each direction of lateral movement of w the needle.
  • the described feeding mechanism is so designed that in one complete rotation of a feed- I controlling eccentric the work is fed twice forwardly and once backwardly.
  • the speed of operation of the machine may be substantially increased beyond the maximum speed capacity of prior machines while, at-the same time, reducing objectionable noise and wear.
  • the provision for convenient adjustments of the relativetiming of the needle-vibrating and feed-controlling eccentrics a large variety of ornamental seams may be readily produced.
  • the feed-bar 50 is, as usual,-raised and lowered by the feed-lift eccentric 58 having the described connections with the slide-block 62, and forward andbackward movements are imparted to said feed-dog 41 by the feed-advance eccentric I'I which functions to rock the seg-r' mental guideway .88 about its fulcrum-axis 18.
  • the rocking movements of said guideway are transmitted by thelink 65 to the feed-rocker 59, 60, 63, as will be readily understood.
  • the shifting movements of the slide-block 61 in the guideway 68 are controlled by the feed- I controlling eccentric 86 through the described connections with said slide-block 61, the throw of the eccentric 86 being such that the slide the fulcrum-axis 18 of the guideway 68.
  • the feed-controlling eccentric 86 is timed for producing fagotlng work, the point of maximum eccentricity. of the eccentric 86' has a position :c
  • block 61 travels from one side to the other of.
  • said position x of the eccentric 86, the slide-block] v v6'l is substantially at :r in the portion of the guideway 68 above the fulcrum-axis thereof.
  • the slide-block 6'! travels downwardly across' the fulcrum-axis 18 in the guideway 68, during the return idle. movement of the feed-dog 41, to bring said slide-block to the point 11" in the succeeding median position of the feed-dog 41 in which the work is fed backwardly.
  • the feed-controlling eccentric. 86 has its point of maximum eccentricity substantially at y to control the feed-dog 41 so that it feeds the work backwardly during a portion of the time when the needle-vibrating eccentric I8 has its angular movements, Fig. 6, to form the short backward stitch a, Fig. "I. Also. that when the feed-controlling eccentric point is at z, the work is fed forwardly during a portion of the time when the needle-vibrating eccentric I8 has its angular movement b to form the relatively longer stitch b.
  • the width of the fagoting seam may be conveniently changed by merely atflusting the eccentricity of the needle-vibrating eccentric I8, by means of the eccentric-adjusting spindle 33.
  • the lengths of the stitches may be conveniently changed by adjusting the cocentricity of the feed-advance eccentric 11, whereby the amplitude of rocking movement of the guideway 68 may be increased or decreased.
  • the present machine may be readily set for producing a large variety of ornamental seams, a few of which seams are illustrated in Fig. 8 of the drawings.
  • Different varieties of seams may be produced by merely changing the timing of the needle-vibrating eccentric I8, which as before described may be accomplished by freeing the eccentric-driving worm-gear 21 from the shaft 5 and turning said worm-gear upon said shaft.
  • seams may be produced by merely adjusting the timing of the feed-controlling eccentric 86, which as also before described may be conveniently effected by pulling forwardly upon the couplingdisk head I82, partly turning the feed-controlling cross-shaft 88 and recoupling the disks 91, I88, in a newly selected relative position thereof.
  • the desired relative position of the disks 81, I88 may be obtained with precision.
  • timing adjustments of the feed-controlling eccentric 88 do not interfere with the proper feeding of the work, because the timing of the rocking-member 68 to actuate the feed-dog 41 and the timing of the feed-lift mechanism is unaffected by said timing adjustments of the feed-controlling eccentric 86.
