-13 cum wince-9a) This invention relates. to sewing machines and more particularlyito ornamental stitching ma chines, the invention having for its primary object-- to provide a quiet running high-speed ornamental theshaft-S carries a counterbalanced crank-disk I connected'by the usual link 8 with a vertically stitching machine, u

A more specific object of the invention isto eliminate from ornamental fstitchingmachines the wear and noise incidental to the use of pattern-cams heretofore employed insaid machines for controlling the stitch-formingand work-feedf ing mechanisms thereof.

Another object of the invention is toprovide'an ornamental stitching machine with conveniently regulatable means for producing various -ornais mental stitching effects of different configura-' tion. Still further objects of the invention will be apparent from the following description and claims.

The invention consists in the needle and' feed.

actuating and controlling mechanism of sewing machines as hereinafter described in connection with the accompanying drawings which "illustrate a preferred embodiment of the invention and in which: a

Fig. 1 represents a vertical longitudim ilsec-' tion, partly in front elevation, of the improved ornamental stitching machine. Fig. 2 represents a bottom plan view of the machine. Fig. 3 represents a vertical section through the bracket-arm standard of the machine on substantially the line 3-4 of Fig. 1. Fig. 4 represents a cross-section through the bracket-arm to include both of the cross-shafts which carry the needle-vibration and feed-controlling eccentrics. Fig. 5 is a detail view in front elevation of the feed-indicator disks. Fig. 6 is an enlarged detail view of the needlevibration controlling connections, with the controlling eccentric therefor'illustrated diagrammatically in the timing thereof for producing o fagoting stitches. Fig. 7-is a'diagrammatic, illustration of fagoting stitches which may be pro- 1 duced by the machine, when the-needle-vibration controlling eccentric is timed as shown in Fig. 6.-

which may be produced by the machine, by merely changing therelative timing ofthe needle and feed-controlling eccentrics. Fig. 9 isj'a diagrammatic representation of the feed-controllingoon-- 'nections.

The sewing machine illustrated in the drawings has theusual work-supporting bed-plate I, from one end of which rises the tubular standard 2 of l a bracket-arm 3 whichoverhangs'the bed-plate I Fig. 8 illustrates, diagrammatically, several of various kinds of ornamental stitching 'efl'ects aled in the bracket-arm], to

Rotatably Jo extend horizontally lengthwise thereof, is a main actuatingor'needle-reciprocating shaft 5 carrying at one" end a beit-pulley 8. At its oppositei'end,

I ally hung" at its upperend upon a fulcrum-pin l2 the bracket-arm head-l. 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. At its opposite end, the. pitmaniG-has a split strap -'l'| embracing a rotary needle-vibrating eccentric l8 constructed substantially as more-fully disclosed in the U. S. patent to C. F. Gray, No. 1,020,089, Mar. 12, 1912.' 'In general, the eccentric l8 has an enlarged shaft-aperture l9 and extends laterally from a frame 20 adjustably'carried by a disk 2i secured bya screw 22 upon a cross-shaft 23. The

'cross-shaft-a is disposed below and substantially 25 normal to the needle-reciprocating shaft 5, being :jour'naled at the front of the bracket arm 3 in a bearing-provided by a detachable cap-plate 24 and at its rearward end in a frame-boss 25. Ad-

Jacent 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 2'l/is preferably secured upon the shaft 5 to providefor angularly adjusting said worm-gear 21, thereby to change the timing of the eccentric I8. To this end, the worm-gear 21 has a hub "extending into anannularly recessed collar 29 secured by screws 30'upon the shaft 5,

said collar 2! being'secured to the gear-hub 28 40 by set-screws II. By freeing the set-screws 3i, the shaft 5 andzworm-gear 21 maybe relatively "rotated to-change the timing r the eccentric Iii,

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.

In the'presentcase, the ratio of the gears."-

and 21 is such that the cross-shaft 23 rotates once for six rotations of the needle-reciprocating shaft 5. Consequently, the needle l0 reciprocates six 5 times in each complete rotation of the eccentric 18, i. e., the needle'reciprocates three times while moving laterally in one direction and three times in its return lateral movement to complete. sixthcycle. amplitude of the complete the width of the ornamental seam is determined 18, which may be effected by means of the usual regulating spindle 33, as disclosed in said prior Patent No. 1,020,089.

Cooperating with the needle III, in the formation of lock-stitches, is 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. 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| which, in turn, is journaled to rock in spaced bearing-lugs 42 and 43 depending from the bed-plate I. At its end opposite to the bevel-gear 39, 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| receiving a slide-block 52 connected by a pivot-bolt 53 to a crank-arm 54 clamped upon one end of the feed-lift rock-shaft 4|. Secured upon said feed-lift rock-shaft 4|, at the opposite end thereof, is a crank-arm 55 connected by a pivot-bolt 56 to the lower end of a pitman 51. 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| and journaled in bearinglugs 5| and 52 depending from the bed-plate I. 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| at the lower end of a bracket 12 secured by screws 13 to the under side of the bed-plate I.

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,

in accordance with the disclosure in the U. S. patent to J. H. Stearns, No. 2,029,278, Jan. 28, 1936, although any other suitable or desired form of adjustable eccentric may be employed. From the foregoing description, it will be understood that the feed-dog 41 derives work-advancing and return movements of variable amplitude from the eccentric 11 and that said work-advancing movements are timed to occur when the feed-dog 41 is raised by the feed-lift mechanism actuated by the feed-lift eccentric 58.

in order to control the effective action of the feed-dog 41 automatically, 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. At its upper end, the link 19 is connected by a ball-joint to an arm 8| of a two-armed lever 8|, 82 fulcrumed upon a pivot-screw 83 threaded into the inner wall of the bracket-arm 3, the fulcrum-axis of the lever 8|, 82 being substantially parallel to the crossshaft 23. The arm 82 of the lever 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. 4 of the drawings, 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| suitably fixed in the front wall of the bracket-arm 3.

Secured upon the sleeve 90, by a set-screw 92, is the hub 93 of a spiral gear 94 in mesh with a spiral pinion 95 suitably secured upon the needlereciprocating shaft 5, the ratio of the gears 94 and 95 being such that the cross-shaft 88 rotates once for three rotations of the needle-reciprocating shaft 5.. The spiral gear preferably has its side face annularly recessed adjacent the feedcontrolling eccentric 85 to receive a disk-flange 95 of said eccentric.

At the front side of the bracket-arm 3, 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. By uncoupling the disk-flange 91 and coupling-disk I00, 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.

The sewing machine hereinbefore described is particularly adapted for producing ornamental stitching, commercially known as fagoting. As illustrated diagrammatically in Fig. 7 of the drawings, 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. I

While the .fagoting seam above described is well known in the art, the prior sewing machines constructed toproduce'fagoting seams were provided with suitably timed pattern-cams having follower-guiding tracks of the requisite shapes to vibrate the needle laterally and to control the feeding of the work. These patterncams imposed definite limitations to the maxi mum speed of operation of the machines and to the varieties of ornamental seams capable of being produced with the respective cams in the machine.

In the present machine, as hereinbefore structurally described, 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.

Likewise, instead of employing a pattern-cam for controlling the effective operation of the feeddog, 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. By employing eccentrics for the purposes described, instead of pattern-cams, 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. Furthermore, by 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.

tion of the stitch a of Fig. 7, and successive angular movements b, c', d, e, f in the formation of the remaining stitches b. c, d, e, I, respectlvely, pl the seam. While said; angular tricity are equal, it will be noted that the effective needle-vibrating components of the angular movements b" and e, while substantially equal to each other, 'are longer than the effective, substantially equal needle-vibrating components a, c, d and f. Byrelating the lengths of said effective components to the stitches com,-

prising a fagoting cycle, it will be observed that the eccentric functions to vibrate the needle [8 -movements ofthe point of maximum eccenso as to produce four relatively short stitches a, c, d and I of substantially equal length and two relatively longer stitches b and e, ofsubtions thereof, but also upon the feeding mechanism which is illustrated diagrammatically in Fig. 9 of the drawings. The feed-dog 41, carried by. 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. In any ofi-center position of the slide-block 61' in itsguideway 68, 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. When the feed-controlling eccentric 86 is timed for producing fagotlng work, the point of maximum eccentricity. of the eccentric 86' has a position :c

in a median position of the feed-dog" in one forward work-advancing movementthereof. In

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. In

a one-thirdrevolution of the eccentric 86, from the position x to position 3 of its point of maximum eccentricity, 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.

In the next one-third revolution of the eccentric 86, from y to z, the slide-block travels upwardly across the fulcrum-axis 18 of the guideway 68 to substantially the point a, during. the

movement to a median positionrof forward feed ing movement.

point :r, the slide-block 61 travels slightly up-".

wardly and then downwardly to the position z' thereof wherein the feed-dog 41 'is again advancingthe work forwardly.

From the foregoing, it will be understood that v for fagoting work, 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. Still furthen'that when the feed-controlling eccentric point is at x, the work is again fed forwardly during a portion of the time when the needle-vibrating eccentric I8 has its angular movement '0' to form the succeeding shorter stitch 0. During the remaining half of the fagoting cycle, the above described control of the feed-dog 41 is repeated, as will be self-evident.

Obviously, 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. Also, 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.

In addition to fagoting work, 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. Other varieties of 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. By means of any suitable indicator-expedient, the desired relative position of the disks 81, I88, may be obtained with precision.

Still further varieties of ornamental seams may be produced by adjusting the timing of both the needle-vibrating eccentric I8 and the feed-controlling eccentric 86, as will be apparent. In connection with the timing adjustments described, it is to be understood that said adjustments do not interfere with the comple mental action of the reciprocating needle I8 and rotating loop-taker 34 to form. stitches. The loop-taker 34 accommodates the maximum lateral throw of the needle I8 efiected by the needlevibrating eccentric I8 of the machine. For still wider lateral throws of the needle, any wellknown or other suitable device may be employed either to accelerate and retard the loop-taker or to bodily shift the loop-taker laterally in timed relation with the needle.

It is also to be understood that the 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.
