SPECIFICATION forming part of Letters Patent No. 459,036, dated September 8, 1891.

Application led August 4, 1890. Serial No. 360,848. (No model.)

To @ZZ whom. it may concern:

Be it known that l, CHRISTIAN DANCEL.,of Brooklyn, county of Kings, State of New York, have invented an Improvement in Tax- Thread Sewing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object the production of a novel machine for sewing with wax-thread, the stitch being made from two threads, one manipulated by a hooked needle and the other by a shuttle, the machine herein represented being adapted for sewing outsoles to welts in the manufacture of boots and shoes.

The machine herein to be described contains a straight hooked needle and a curved awl, both adapted to work upwardly from below the work-support, upon which the sole is supposed to rest, the needle-bar-actuating mechanism and the awl-actuatin g mechanism having combined with them devices whereby they are adapted to accommodate themselves to varying thicknesses of material, the point of the awl and of the hooked needle always rising for substantially the same distance through the top of the welt, whatever maybe the thickness ofthe outer sole and welt. The fulcrum-posts for the levers employed for actuating the needle-bar and awl-carrying lever are varied in their position by or through the presser-foot, which bears upon the stock, which in practice will be the welt, the sole at such time resting upon a fixed work-support. The stock is fed by means of feeding devices, which clamp and move it positively. That member of the feedingclamp against which the outer sole bears has, as shown, a knife located just in advance of the needle to cut a groove or channel in the sole to conceal the stitch, for in a machine wherein the shuttle is double-pointed and enters successive loops of needle-thread firstfrom one and then from the other side thereof it will be remembered that every other loop of needle-thread is twisted out of line, and were it not for the groove in the sole the stitch would present to t-he eye a zigzag appearance, which would be apt to render the shoe unsalable. This groove, if made in the sole before putting it in the machine, must be made in a machine wherein the shoe is held on a last, the upper serving as the gage to define the distance of the seam uniting the welt and outsole from the upper. To however avoid this extra operation, the channel-groove maybe out in thesewing-machineat apoint immediately before the stitch-makin g point and just previous to making the stitch. The needle-thread is ledfrom a suitable spoolor bobbin to a thread eye, whichis connected with the rising and falling presser-foot, and the said thread is taken from the thread-eye by a forked thread-carrier, which deposits a quantity of the said thread upon a loop-sustainer, which is maintained in position while the thread-carrier deposits the needle-thread held by it into the hook of the needle. This having been done, the said thread-sustainer is retracted or moved out of the way, it coming into position again when the thread-carrier is fully lifted and the needle is just about penetrating the material, the thread-sustainer remainin g stationary while the needle-thread is laid in loop form above it, as described. This thread-sustainer is also adapted to rise and fall together with the presser-foot, according to the variations in thickness of the stock, so that it may always occupy the proper posi'- tion to correctly co-operate with the threadcarrier whether the stock is thick or thin. The shuttle used is double-ended and adapted to make a stitchin each direction of its movement, and the shuttle-race is completely cut through crosswise and has combined with it an oscillating loop-spreader, which takes the loop of needle-thread while held in the hook of the needle and carries it laterally, thus spreading the loop to be entered by the shuttle. (lo-operating with the loop-spreader is a cast-off for throwing the loop ont of the eye of the needle on the back-stroke of the spreader. The needle-bar as it rises actuates a lever to pull off from the thread-supply a quantity of thread, which varies in amount according to the thickness of the stock, the needlethread at such time being clamped between the pull-off lever for the needle-thread and the thread-eye referred to. The needle-thread is passed over a take-up, which acts not only IOO to give up thread to the thread-carrier during its descent, but also to give up thread to the needle while descending and to the spreader, and thereafter to take up the loop of needle-thread. While the needle is completing its descent the needle-thread is unclamped between the take-up and the measuring-roll and clamped between the measuring-roll and the thread-supply, so that the ro thread previously drawn off positively from the thread-supply has an opportunity to come into the stitch then being made;

Figure 1 is a top or plan view of a machine embodying myinvention; Fig. 1, three views of the shuttle enlarged 3 Fig. 2, a lefthand side view thereof; Fig. 8, a front elevation thereof; Fig. 4, a right-hand end view. Figs. 5 and 6 represent the shape ot' the awl and needle-actuating cam-grooves. Fig. 7 is zo a partial section below the dotted line Fig. 4; Figs. S and 9, details of the cam-grooves in the peripheries of the feed and spreader cams B C; Fig. 10, a diagramshowingthe measuringroll, the actin g portion of the thread-clamp,the 2 5 tension device, the needle, the thread-eye, the Vthread-carrier, and part of the take-up; Fig. 11, a detail showing part of an outsole and welt with the hooked needle therein and about to be supplied with a measured loop of thread 3o from the thread-carrier, the presser-foot resting on the welt, the thread-sustainer yet supporting the loop of needle-thread about to be drawn through the stock by the hooked needle. Fig. 12 shows three views of that inem- 3 5 ber of the feed-clamp which is provided with the cutter; Fig. 13, a top View and side elevation of the loop-spreader and cast-off en-V larged; Fig. 14, three views of the shuttlerace detached, and Fig. 15 two views of the 4o measuring-block.

Referring to the drawings, A represents the framework of the machine, which may be of any suitable shape to support the working parts. This frame-work has suitable bearings for a main or cam shaft A upon which are secured cams B, C, D and E and a pinion F, (shown by dotted lines in Fig. 4,) it being located between the cams C and E,its purpose being to engage and rotate the cam-gear E",

5o mounted upon a stud E2, the said cam-gear having a cam-groove in one side of it, as represented in Fig. 4, which receives a roller or other stud E3 on a lever E4, pivoted at E5 upon a part of the frame-work, the said lever at its upper end having a swiveled joint E,

to which is connected by screw E7 a shuttledriving rod E8, having suitable drivers e e', (shown in Fig. 4,) which act against the opposite ends of the shuttle E9, (shown separately 6o in Fig. 1%) the said drivers acting in usual manner to reciprocate the shuttle and carry it through the loop of needle-thread,to be described; but the speed of rotation ot the camgear E is one-half that of the main shaft A',

so that the shuttle is passed through one loop in one direction and through the next loop in the opposite direction, thus making a stitch at each stroke of the shuttle in each direction. The rod E8 has an additional bearing in a lug or ear E10, secured to or forming part of the shuttle-race E12, which is attached by a suitable bolt or bolts E13 to the top plate of the frame-work A. This shuttle-race is shown separately in Fig. 14, where it will be seen that the race has a broad transverse slot 40, through which works the spreader ZJ, to be described, (shown separately in Fig. 13,) the said race having at its upper side a work-support b', provided with a groove b2, up through which the needle and awl rise, the one to perforate the material and the other to enter the hole made by the awl.

The portion b4 of the shuttle-race acts as a support for the under member 010 of the feedclamp. It. will be noticed that this shuttlerace is substantially straight at its upper side, but that it is slightly inclined from a horizontal plane and that the work-support is elevated above it, such construction permitting the shuttle to move in a straight line, and also enabling the shoe to be tipped as required, in order that the stitch may be made through the welt and outsole close to the inseam or to the upper next to the last.

The shuttle will be provided with any usual tension mechanism, and the shuttle-race and shuttle will be heated in any usual manner to keep the shuttle-thread warm and the wax on the thread soft.

' The spreader b (shown separately in Fig. 13) is composed, essentially, ot' an upright arm hayng a groove 2 for the reception of the loop of needle-thread, the said arm being Vconnected to the upper end of an oscillatingn shaft Z914, having at its lower end a pinion b5, which is engaged by a toothed segment b, pivoted at bi, the said segment having adjustably connected with it by a set-screw bs a link b9, in turn jointed at its opposite end to a lever B', having its fulcrum on a stud B2 and provided with a roller or other stud B3, which enters the groove 3 (see Fig. 9) in the cam C, the shape of the said cam being such as to oscillate the said shaft for about onehalta rotation. The'shatt b14 has connected to it a cast-off U0, (shown in Fig. 13,) it having a point 4. In operation this spreader and cast-off swing backward and forward through the transverse slot in the shut tlc-race, the center of motion of the pinion lb being in the vertical plane in which the shuttle moves.

The cam B has at its outer side (see Fig. 4) a cam-groove 5, 'which receives a roller or other stud at the inner end ot a rocking lever B, having its fulcrum at B in suitable brackets B7, depending from the upper part of the frame-work, the upwardly-extended arm B of the said rocking lever carrying the movable member 41 of a thread-clamp, to be described, the said arm being shown in cross-section in the detail Fig. 10. The cam B (shown seprately in Fig. S) has at its periphery a cam-groove 6, which receives a roller` or other stud c of a lever c', having its fulcrum at IOO IOS

c2 and slotted at its outer end, as at c3, to receive a stud c4, connected with the feed-regulating lever e5, pivoted at 7 on the lever c, pivoted at cT (see Fig. 1) upon the frame work and connected by a jointed link es with an ear on the frame c, carrying the under meinber c10 of the feed-clamp. The frame e9 is pivoted upon avertical stud-screw cl2, aboutwhich stud-screw the feeding-clamp is vibrated when feeding the work, the length of the vibration being made greater or less by moving thefeedregulating lever c, as will be well understood. The frame c9 has a horizontally-arranged stud-screw cl3, which serves as the fulcrum for the lever or arm c, on which is mounted the upper member eli ofthe feed-clamp. The mem ber cli of the feed-clamp is normally acted upon by a spring c", which may be adjusted by or through a thumb-screw C18 as to its strength, the said spring permitting the upper member to rise and fall and to adapt itself to the varying thickness of the sole and welt or stock passing between it and the lower member of the clamp. To lift the upper member of the clamp by hand, I have connected with the lever cAl alink 020, (see Fig. 4,) which is attached to a lever C21, pivoted at c2:2 upon the measuring-block 023, to be described, the said measuring-block being shown best in the detailFig. 15.

The lower member cw of the feed-clamp has connected to it by screws 8 (see Fig. 12) a knife f, which is located immediately in front of the stitch-making point, so that it cuts a groove in the sole just in advance of the sewing, the needle and awl entering the said groove, the stitch being buried therein. The knife is so shaped as to spread and somewhat open the groove made by it in the sole.

The measuring-block o23 forms a part of a slide c2", fitted vto rise and fall in a suitable groove in the upright- AX, iiXed upon the frame-work. The slide cmhas a stud c25, (see Figs. 4. and 15,) which forms the fulcrum for the lever C26, which is forked at its front end, as shown in Fig. 2, to embrace a loose block fitted upon a stud-screw C27, attached to acarriage C28, adapted to slidein a suitable groove in the arm or lever g, to which is bolted the pressenfoot g', the said carriage having pivoted upon it at c25 (see Fig. 3) the thread-carrier g2, it having a roller or other stud g3, which enters a cam-slot g4 in a plate g5, attached to the arm or lever g, the lower end of the said thread-carrier being bifurcated, as at 12, and being notched at 13 (see Fig. 11) substantially at right angles to the notch or bifurcation 12. The rear end of the arm or lever g is pivoted by the stud g, (see Fig. 2,)

vso that the presser-foot carrier at the under side of the said lever normally rests by grav ity upon the welt vw. The stud c25, extended from the slide 024, is also extended through the lever g, so that'as the position of the said 1ever is changed by the thickness of the stock under the presser-foot carried by it the said lever will correspondingly raise or lower the said slide cit, and with it the fulcrum-pin c'25 for the lever C2G, such provision enabling the thread-guide to, always move the same distauce--namely, downto the welt w, (see Fig. 11,) no matter where it may be, and up to a position above the thread-eye to be described, notwithstanding variations in thickness of the stock. The presser-foot has connected with it a thread-eye 71 through which the needle-thread is led on its way to the work.

The rear end of the lever c2G has jointed to it a link 71', whiehin turn is jointed to arightangled extension (see Fig. 1) of a lever h2, mounted on a stud 713, the lower end of the said lever having a roller or other stud, which enters a cam-groove h4, shaped as shown in dotted lines, Fig. 2, and made in one side of the cam D, the said cam, lever, and link vibrating the said lever c2 to reciprocate the thread-carrier. j

The lever g (see Fig. Li) has pivoted upon it a lever m, the front end of which is connected by a stud-screw 1l to a slide my', upon which is pivoted by stud-screw 15, the threadsustainer m2, (best shown in Figs. 1, 3, 4, and 11,) it having a point 16, suitably grooved to prevent the needle-thread slipping oii from it. The thread-sustainer has jointed to it by stud-screw 17 a link m3, (shown by dotted lines, Fig. l, and full lines, Fig. 1,) which in turn is jointed to a lever mi, pivoted at m5 upon apart of the framework, the lower end of the said lever having a suitable roller or other stud 1S, which is acted upon at suitable times by a camsurface 19 19X (see Fig. 9) at the periphery of the cam C. rllhe rear end of the lever in is jointed by link m7 to the bracket cap-plate m8. This cap-plate has suitable bearings for a stud n, upon which is mounted the take-up lever n', having a suitable sheave n2, the said take-up lever (see Fig. 2) having a second arm 72,3, which is slotted for the reception of an adjustable stud-screw ai, which is connected by link 'n.5 with the lever n, mounted on the stud h3, before described, the lower -end of the lever n having a suitable roller or other stud, which enters a cam-groove 2O at the outer side of the cam E.

The upright AX has a stud D', upon which is mounted the awl-carrying lever D2, it having at its front end, as herein shown, a suitable awl D3, the awl being held in place in any suitable manner. rlhe awl-carrying le- Ver D2 has jointed to it a link D", in turn jointed to alever D5, having its fulcrum upon a pin DJ- in a fulcrum-post D7, provided at its lower end with a fixed collar DS and at its upper end with an adjustable nut D9, which nut rests upon the measuring-block C23, or upon a sound-deadening washer D30, (see Figs. 3 and 13,) interposed between the block and nut. The nut D may be adjusted on the fulcrum-post D7 to compensate for any shortening of the awl due to grinding. The lever D5 has at its rear end a suitable roller or other IOO IIO

IZO

stud D60, (see Figs. 2 and 5,) which enters a cam-groove 21 in the side of the cam D. (See Fig. 5.)

The cam C has at one side of it a camgroove 22, the shape of which is best shown in Fig. 6, which receives a roller` or other stud 23 of a lever H, having its fulcrum at H on ay fulcrum-post H', provided at its lower end with a collar H2 and at its upper end with a nut H3, which rests normally upon the measuring-block o23 alongside of the nut D9. The front end of the needle-bar-actuating lever H is provided with sector-teeth, which engage teeth of the needle-bar H4, it being a straight bar provided withastraight hooked needle p.

In this my invention the needle and awl work in the same vertical plane, and both rise in the groove h2 in the Worksupport b', the awl-inaking a hole through the outer sole and welt, and then being withdrawn to let the needle p rise up through the sole and welt, it passing through the hole made by the awl. This arrangement of the awl and needle at the same side of the stock and in the same vertical plane, substantially at right angles to the line of stitching, enables one or the other to remain in the stock at the same point for a longer period than is possible when the awl and needle are arranged one alongside of the other in the direction of the length of the stitch, and in this arrangement the awl and needle always remain in the same vertical plane with relation to the work-supportthat is, neither of them has to do with feeding the material.

By dispensing with the awl-feed heretofore used the machine is simplified, and by causing the needle to enter the aWl-hole just as quick as the awl leaves itwithout moving the shoe prevents any accidental displacement of the shoe, which Would happen if the awl was arranged at the side of the needle and the material had to be fed in order to place the awl-hole over the needle. The needle-bar has a dog fr attached to it by a suitable screw r', which dog, about as the point of the needle enters the sole, strikes the end of a lever fr?, pivoted at r3 on a stud of a hanger rx, secured to the framework, the opposite end of the said lever, called the pulloif lever, having a sheavefr4. (Shown chiefly by dotted lines in Fig. 4 and by full lines in Figs. 7 and l0.) This sheave acts upon a bight of the needle-thread t. The needle thread, taken from a suitable thread-supply, which may be a cop, spool, or bobbin, is led over any usual tension device, as t', thence under a roll t2, thence up over a roll t3, down through a slot (see Fig. l0) in the frame-work under the sheave r4, and up over the sheave n2, down to and through the thread-eye h to the work. The needle-thread, it will be noticed, passes at opposite sides of the clamping-block 4l at the upper end of the arm B of the lever B5, and as the said arm is moved to the right or left clamps the said thread between it and the frame-Work. Vhen the dog r meets the pull-off lever r2 to turn it, the thread is clamped between the clamping-block and the portion 24 of the frame-work, or at the left, viewing Fig. 10, and at such times the sheave r4, acting on the needle-thread, pulls off the needle-thread more or less in quantity, according to the thickness of the stock, for it will be understood` that the point to which the needle ascends varies through change of position of the fulcrum-post- H', according to the variations in thickness of the stock under the presser-foot. As the dog r acts to turn the pull-oit lever r2 the latter lever acts upon a stud s2, fast-to the clamp-lifting lever C21, and automatically lifts the upper member @15 of the clamp while the feed-clamps are being moved backwardly over the stock, the stock then being held by the needle and also between the presser-foot and work-support, and it is at this time that the groove or channel is cut in the bottom of the outersole,the length of the groove being the distance of the feed.

In operation let it be assumed that the outer sole of the shoe lies upon the worksupport and upon the lower member c10 of the feed-clamp then in its most forward position; that the presser-foot g and the upper meniber 015 of the work-feeding clamp rests upon the welt tu; that the awl has been thrust up through the sole s and welt; that the needle D3 has been carried down into its lowest position; that the spreader b has engaged the loose or active side of the loop of needlethreadjust drawn down by the needle, and that the spreader has been moved to spread the loop of needle-thread across the path of the shuttle then stationary; that the take-up n3 is in its most elevated position; that the thread support m2 is retracted; that the thread-carrier g2 is in its most elevated position, and that the thread-clamp 41 is moved toward the left (viewing Fig. l0) to clamp the needle-thread between the sheave r4 and the takeup sheave n3. In this condition rotation of the main shaft in the direction of the arrow 2S (see Fig. l) will depress the awl,with drawing it from the stock, and as the awl commences to descend the needle-bar commences to rise, the point of the needle entering the awl-hole in the stock substantially as the point of the awl leaves the said hole, the needle entering the awl-hole Without any change in the position of the stock, thus avoid' ing any possibilit-y of displacement of the material. As the awl lcommences to descend, the thread-Support m2 is moved forward, it arriving in its most forward position about as the point of the needle enters the stock, the thread-carrier g2 commencing its descent while the needle is rising through the stock, the thread-carrier in its descent engaging the needle-thread below the thread-eye h and carrying it laterally across the-top of the then stationary thread-support, the thread guide or` carrier descendingin a cam-shaped path to the right of the thread-support (see Fig. 11)

and measuring' off a quantity of the needlethread for the stitch to be made, the threadcarrier taking the thread so being measured olf -by it and carrying itdown to the welt, at which point it meets lthe hook of the needle, the thread-carrier putting the needle-thread in the hook of the needle, as in Fig. 1l. During the descent of the thread-carrier, as described, the take-up also descends,it continulng to descend until the thread-carrier presents the thread held by it to the hook of the needle, when the descent of the take-up stops and the thread-support is quickly withdrawn from the loop of thread placed about it by the threadcarrier leaving the said loop free to be drawn down by the needle in its next descent. lVhile the needle is elevated and in the stock the stock-feeding clamp is moved backwardly or to the right, viewing Fig. 3, the knife 7" then cutting a groove in the sole equal to the length of the feed movement. As the needle descends with the loop of needle-thread so measured off for it, the thread-carrier rises and the take-up con tin ues to descend, giving up thread to the descending needle; but in its descent the thread does not rend through or across the hook of the needle, because thread for that stitch had been previously measured off by the threadcarrier and thread-support. After the needle completes its descent the shaft D" is oscillated to cause the spreader l) (see Fig. l2) to engage the active or loose side of the loop of needle-thread and carryit across the shuttlerace in front of one end of the then stationary shuttle, and during this time the take-up completes its descent, giving up thread to the spreader in order to make the loop of sufficient size for the shuttle. The spreader having come to rest, the shuttle while the takeup is most depressed and while the needle and awl are both depressed below the stock is passed through the loop of needle-thread, and as soon as the shuttle is through the loop of needle-thread the take-up starts to rise and the motion of the shaft b" is reversed, causing the cast-off bw to engage the loop of needle-thread and cast it out of the hook of the needle if said loop has not already been released from the needle, the take-up continuing to rise and the spreader' continuing to move back into its farthest position to the left (viewing Fig. and remaining there until the take-up has nearly completed its movement to take up the stitch, at which time the awl again commences to rise toward the material, the take-up completing its upward movement before the awl engages the material, the feeding-clamp moving the material forward between thc presser-foot and Work-support while the awl approaches the stock, the feed being completed before the awl reaches the outer sole. While the needle rises through the stock the thread is clamped between the sheave r4 and the takeup; but as soon as the needle is in the stock and before t-he thread-carrier delivers the loop of needlethread to the hook of the needle the thread-clamp shifts its position or moves to the right, (viewing Fig-L) clamping the thread at the side all and between the sheave r1 and the thread-supply,`it holding the said thread so clamped until the needle uishes its next descent and the take-up sets the stitch, the thread being released j ust about as the awl commences to enter the outer sole.

am aware that sewing machines of this class have been provided with a pull-olf to act upon the needle-thread before it is passed through the eye of the looper to be supplied to the hook of the hooked needle, the said pull-off being operatively connected with the worksupport through a variablemotion mechanism, whereby the pull-off has more or less movement imparted to it through changes in position of said work-support, such position being determined by the thickness of the stock; but such construction is notherein claimed.
