This invention relates to multiple-needle embroiderinfgg. machines of that type cemprising means for producing a series of par' allel seams with a covering thread led in a` sinuous'path andsecured upon the face of the work by means of said parallel seams, as disclosed in the United States patents to Friederick Mueller Nos. 735,559, dated August e, 1903, and 781,673,'d'ated February 7, 1965; and it has for itsprimary vobject to provide means for laying loops of covering or embroidery thread led from one side et' the stitch line between stitches et' one of the parallel seams and varound stitches of another oIn the parallel seams.

In its preferred form, the improvement comprises a coveringor embroiderythread carrier reciprocating vat one side of and parallel 'with the line of seam and a spreader reciprocating transversely of' the line of seam and in liront of the needles and adapted to form and distend loops of the carrierthread rer passage of the needle farthest from the carrier, the carrier being actuated to present its thread-rearward of the adjacent needle but to recede from advance pou sition sufiiciently to enable the spreader to seize its thread between the carrier and the -plast formed stitch of said adjacent needle.

rEhe invention also includes special means for 'actuating the thread-carrier and spreader, means 'lor insuring the proper positioning of the carrier-thread for attachment to the fabric by the stitch-forming mechanism, and feeding mechanism including lateral shifting means adapted to be disengaged at will from vits actuating means and designed to impart step-by-step sideshifting movements to the work to form festoon or other patterns of seam.

The machine is constructed. with the usual irame comprising a bcd-platel and overhanging bracli'et-arin 2 with head 3 in which formed therefor in the head 3 to prevent the' turning or the needle-bar in its bearings.

Cooperating with the needlesl in the production of parallel seams is the shuttle 16l carrying the thread-case 17 and fitted within vPatented July 7, 1914. l Application filed September 15, 1910. Serial No. 58Q,162. i

4is journaled the main-shaft 4l carrying at its i the shuttle race 18 also arranged parallel' with the main-shaft, the shuttle being actuated ,in a well-known manner by the driver 19 ixed upon one end of the transverse rock-shaft 20 having at .its opposite end the crank 21 provided with the crank-pin carrying the slide-block 23 embraced by the forked outer' end 24 of the crank-arm 25 upon the intermediate rock-shaft 26 having upon its opposite end the crank-arm 27 connected by means o'll the screw-pin with one end of' the pitman-rod 29 connected at its opposite'end `with a depending arm 30 of an angle-lever fulcrulned at 31 and having a lateral arm 32 carrying' a ballfstud 33 which is embraced by a strap at the lower end of the connecting rod 34 which has at its oppoof the guide-strips 42 secured in position by` the fastening screws 43.

The feed-dog is provided with apertures 36x entered by fastening screws 44 by which it is secured upon the vcarrier 45 formed with aI hub 46 which is slidingly fitted upon the supporting pin 47 mounted in theupwardly' projecting arms 48 of the feed rockshaft 49 mounted upon the usual conicalpointed center-screws 50. The rockingmovements 'are imparted to the feed rock-shaft through the crank-arm 51 fixed upon the 'rearward end of the rock-shaft 49 and piv- A otally connected with the lower end of the link-bar v52 whose opposite end is provided With the yoke 58 embracing the collar 54 fitted upon the feed-actuating eccentric 55 upon the main-shaft 4. The link-bar 52 carries near its yoke 53 a lateral stud 56 embraced by one end of the link 57 whose opposite end embraces astud 58 carried by an 'arm 59 of the feed-regulating angle-lever' whose other arm isi-provided with a thumbnut GO for shifting the same to vary the p0- sition o f the fulcrum-stud 58, as in the regullar feeding mechanism of the' wellknown Singer oscillatingv shuttle machines. :The lower side of the feed-'dog carrier 45' is formed with a longitudinal groove 61 entered by the roller (32 having a rocking connection with a lateral :arm 63 fixed upon the forward end of the feed-lifting rock-shaft 64 mounted upon the conical-pointed centerscrews 65 and having fixed upon its rearward end the crank-arm 66 pivotally conpnected with the lower end of the pitman-rod 67 having at its upper enda strap '8`e1n- .bracing the feed-lifting eccentric 69 upon the main-shaft. The feeding mechanism imvparts to the work advance movements transverselyj of the'bed-plate and of the line of 'the needles.-

Mounted u on affulcriim-pin 70 fixed within the head 3 of the bracket-arm isl the hub`71 of-a vibratory lever'having a depending arm 72 formed with a slideway in which is itted the shank 73 of the threadcarrier'having the transverse tubular guidemember 74 with thread .orifice 75. The guide-channel of the vibrator-y arm 72 is closed by a cap-plate 7G carrying the screw 77 between which and a pin 78 near the.

upper end of the carrier-shank 73 extends' the spring 79 acting to normally force the The top of the.

carrier downwardly close to the work. The upwardly extending arm 80 of said vibratory lever is provided with a -yoke 81 einbracing an actuating cam 82 formed upon a plate 83 carried by the needle-actuating crank-pin 8, so that foreach reciprocation of the needle the carrier receives a corresponding reciprocatory movement in the d1- rection of feed and at one side of the needles.

The forni and position of the cam 82 is such' initial position as the needles are rising from the work.

The spreader comprises theshank 84 having near its point the laterally extending curved blade 85 with depending barb or spur 86 with downwardly inclined lower edge and so mounted as to move transversely of thje direction of fee'd in front of the needles to brush aside the carrier-thread extending between the member 74 andl the Work when moving to extreme advance position, but in 'its return movement Ato seize saidthiead andfform a loop inthe same which is distended sufficiently to embrace the path of the needle 14;L farthest from the carrier in the extreme retracted position lof the spreader. The spreader-shank 84 is se'- cured by means of screws 87 to the depending'lateral arm 88 of arocker whose hub 89 is mounted betv-.feen collars 90 upon the presser-bar 91 and provided with a second lateral arm 92 pivotally connected by means of the pin 93 with a link 94 whose opposite end is connected. by the pin 95 with a crankarm 96 upon the rock-shaft 97 slidingly mounted' within the bracket-arm head The rock-shaft 97 has Ifixed upon its opposite end the crank E38-carrying a ball-stud 99 embraced' by the strap '100 at the Aforward end of a pitman-rod 101 provided at its opposite end with l'a strap 102 embracing Ithe ball-stud 103 upon the upper arm 104 of a rock-lever fulcrumed at 105-upoii the bracket-arm 2 and carrying upon its lower arm 10G the stud 107 entering the peripheral groove 108 of the actuating cam 109 fixed upon the main-shaft. The mechanism just described is constructed and arranged to impart to the spreader about as the needles enter the Work in each stitch-forming cycle an advance movement, from initial )osition at the slide of the needles opposite tliat occupied by the `thi-ead-carrier (Fig. 10), across the path of the `thread-carrier in advance ofthe needles 1l) .and a return to initial position about," as the needles are rising from the pivotal pin 112 the lug 113 upon the upper side of the pressure-plate 114 formed in advance of said lug with the needle-'aperture 115 entered by the taperedstitch-nger 116 whose forwardly extending' shank 117 is secured within a groove 118 therefor in the upper face of the pressure-plate 114 by means of the clamp-screw 119. Arranged in advance of the needle-aperture 115 and beneath the path of movement of the threadcarrier 73, 74 isa transverse carrier-thread deiiecting rib in the form of a wire 120 secured in position by means of the screw 121.

The object of the rib 120 is to support thel carrier-thread upon the side of the spreader'- path opposite the carrier member 74 slightly above the upper face of the presser-foot to insure its seizure by the spur 36 of the spreader; while the object of the threadfinger 116 is to afford a stripper intermediate the needles for the work during the rise of the needles.

The presser-bar is provided with the usual iixed collar 122 with rearwardly extending angular arm 123 for engagement with the camshaped lifting lever 124 and other presser-lifting means, between which collar- 122 and the bushing 125 vis interposed the spring 126. The presser-bar has adjustably secured thereon by means of the screw 127 theixed collar 128 with forwardly extending arm 129 adapted-for engagement of the lateral roller-stud 130 carried by the upper end of the carrier-shank 73 whereby the lifting of the presser-bar causes the rise of the carrier so as to avoid interference with the upward movement of the pressure plate 114. In practice7 the thread-carrier shank 73 is formed with a slot 73* (Fig. 3) entered by the shank of the screw 7 2 securing the capplate 76 upon the lever-arm 72, and it will thus be seen that the screw 7 2 acting in conjunction with the upper end of the slot 73x may `serve as a stop to limit the downward ino-vement of the carrier-shank 7 3 under the action of the spring 79, in order that the roller-stid130 may normally remain out of Contact with the lifting arm 129 during the operation of the machine. As the spreadercarrier, comprising the members 88, 89 and 92,. is mounted upon the presser-bar inl ermediate the fixed collars 90, it will be seen that the spreader is also lifted with' the presser-bar, the rock-shaft 97 rising there-l` with by reason of itsdescribed connections, with the spreader-carrier.-

The pressure-plate lug 113 is bifurcated to uto the'l normal direction "of feed or receive the .spreader-linger 131 which extends forwardly intermediate the needlepaths and above the needle-aperture 115,

Iand its forward. portion is wedge-shaped and downwardly and'backwardly inclined, as'represented particularly in Figs. 3, 5 and 6. Its object is to maintain the needlethreads separated between the work and the needle-eyes while the needles are rising and' the covering thread is being drawn laterally, so as to prevent'the reduction in the gage of the seam which would otherwise be produced by reason of the tension upon the covering thread. A

In order to effect the previously described sidewise movement 'of the feed-dog for pro- Aduction of` embroidery stitching in different patterns, the sliding feed-dog carrier 45 is provided'with -a depending ball-stud 132 embraced by a strap 133 at the forward end of 4a pitman 134 provided at its opposite end with a strap 135 embracing a similar stud 136 upon the depending arm 137 of'a` rocklever fulcrumed upon the fixed stud 138 and having an upwardly extending arm 139 carrying a roller-stud 140 which enters the pattern cam-groove 141 of a cam-wheel 142 whose hub 143 is mounted upon the stud -144 upon which it is removably confined by means of the nut 145 and washer 146, a flat nut and washer with its ends rest-ing upon the outer face of the cam-wheel 142 to insure against overthrow of the cam-wheel in its step-by-step rotary movements. Secured by suitable means to the cam-wheel 142 is a ratchet-wheel 148, and loosely mounted upon the stud 144 is the hub 149 of a rocker having an upwardly extending arm 150 provided with a stud-pin 151 upon which is mounted the awl 152 pressed in normal engagement with the teeth of the ratchetwheel 14S by means of a flat spring 153 secured upon the arm 150A and pressing upon an angular projection 154 upon the hub ofthe pawl 152.' By lifting the pawl 15,2 suiiiciently the spring 153 is caused-to bear upon the other face of the projection 154 so as to maintain the pawl out of operative relation with the ratchet-wheel 14S.

The pawl-carrying rocker is provided with a lateral arm 155 having a strap 155X embracing a ball-stud 156 carried by the, eccentric-rod 157 whose upper end is'provided with a strap 15S embracing the actuating eccentric 159 upon the main-.shaft 4. The timingl of the parts is such that, when '95 spring 147 ,being interposed between said the ratchet-wheel 148, an impulse is im- 'partedto the cam-wheel 142 during each advance movement of the feed-dog, whereby the work is nio-vedlaterally as well as longitudinally for shiftingy the work at an angle advance movement of the work.

The bearing bracket 160 sustaining the fulcrinn- studs 138 and 144 is provided with a socket 4161 directed toward the fulcrumstud 144, in which is fitted the latch-plug 162 having toothed upper end'for engage` ment with the peripheral teeth of the ratcheti wheel 148 and formed'with a recess in its opposite end between the inner extremity of which and the bottom of the socket 161 is interposed the spring 163 for maintaining the plug 162 normally in contact with the ratchet-v'vheel, to insure against the retrograde movement of the latter during the retraction of the pawl 152% after each opera tive ratchetovheel advancing` movement.

The throat-plate 39 is provided with depending spaced blocks 164 secured thereto by means of screws 165 to embrace the opposite edges of the feed-.dog 36 as represented in dotted lines in Fig. 95 and the side-shifting movements of the feed-deg are therefore' communicated through these blocks to the throat-plate which slides along the bedplate, so that no clearance need be provided between the feeding surfaces of the feeddog and the apertures therefor in the throatplate to-ccmpensate for the lateral movements of the feed-dog as has been necessary heretofore. This feature of the present improvemcntis important, for the reason that with extreme widths of ornamental seam which the present improvement is designed to produce it is necessary that the work should be eiiectively supported intermediate the parallel operative surfaces of the feeddog when the latter are lowered, and according to the present improvement the feed-dog apertures may be formed to closely embrace the operative portions of the feed-dog asin ordinary straight-away stitching irnmliines.

In threadingthe machine, the needlethreads a and c* are led from the spools 166 upon the pins 167 through the tensions 16S, thence downwardly around thc guide-pulleys 169 and stationary guides 170, upwardly through the eyes 171 of the take-np lever 172 fulcrumed at 173 and carrying the roller-stud 174 entering the cam-groove 175 of the cam-cylinder 7, from which take-np the threads pass through the thread-guide 176 and guide-eyes 177 in the neelille-clamp 13 to the eyes' of t-he respective needles'. Thecovering thread is led from the source of supply through suitable eyes in the washer 178,'between the disks of the tension 179, and thence through the guide-aperture 'l' in the discharge orifice of the carrier member 74.

.ln the operation of the machine, when the needles are in eXtreme upper position the ,thread-carrier and spreader occupy the positionsxepresented in Fig. 10, the former having its orifice disposed rearward of the needle 14 'and the latter being' disposed at the opposite side of the needles with its barb or spur positioned to hold the loop of covering thread c so that one limb is led from the orifice of the carrier rearwardly ofthe needle 14 and forwardly of the needle 141L and the other limb of said thread-loop c rearward of the needle 14u and in advance of the previous stitch of the needle 14. The covering-thread-handling elements remain in these positions until the points of the needles'- have passed below'. the covering thread, when the carrier first begins torecede and the spreader subsequently begins its recession, successively reaching their eX treme positions as represented in Fig. 11 just about as the needles reach their lower positions. While the needles are rising, the thread-carrierand spreader effect their return movements to their respective initial positions preparatory to a succeeding stitchforming operation,- the needle-thread loops having meanwhile been locked Wit-hin the work by the shuttle-thread b. Theadvance of the work under the action of the feeding` mechanism subsequent to the emergence of the needles and before their succeeding descent produces the lead of the covering `thread from the last stitch of the needle thread o somewhat inclined to the direction of feed. into the throat of the barb S6 rearward ofthe needle 14L and between the same and .the previous stitch of the needle-thread of, as will be seen by reference to Fig. 10.

The present improvement differs from others providing for the sinnous laying of the covering thread aro-und cach alternate stitch of each needle, in that by its operation every seam stitch of each needle embraces a loop of the covering thread, whereby the face of the work is more cii'eotively covered and the spacing of the stitches may be cor respondingly increased so as to proportionntely increase the output of the machine.

The improvement is susceptible of consid-A erable modification inthe construction and arrangement of its component parts without departure from the scope of the inventiomnnd it is evident that. it is applicable to different types of machines and' is not limited to those having only two needles.
