SPECIFICATION forming part of LettersPatent No. 615,263, dated December 6, 1898.

Application filed August 13,1895. Renewed April 11, 1898. Serial No. 677,248. (No model.)

To all wiz/0m t Hefty concern:

Be it known that I,-ELOU1LD DUPLEssIs, of the city of St. Hyacinthe, in the county of St. Hyacinthe and Province of Quebec, Canada, have invented certain new and useful Improvements in Sewing-Machines; and I do hereby declare that the following is-a full, clear, and exact description of the same.

My invention relatesimore particularly to 1o the type of sewing-machine illustrated and described in pending applications led by me April 11, 1898, Serial No. 677,246, and April ll, 1898, Serial No. 677,247; and the object of the invention is to provide certain new and I 5 useful instrumentalities or tools consisting of a presser-foot, a work-table, and perforating mechanism, to be hereinafter described and claimed, and to combine such instrumentali# ties with the stitch-formin g instrumentalities zo and feed mechanism of the sewing-machine set forthhin the first above-mentioned pending application in order that such machine (which is adapted in one application to do through-and-'through sewing where a horn is required, as in what is known as the McKay style of work, and in the other application is adapted to do welted work) may be converted into a machine for doing edge-stitching, a third object of the invention being to pro# 3o vide a machine for doing edge-stitching that will be less expensive toconstruct, have less parts to operate, and that will be capable of running at a much higher' rate of speed than the ed ge-stitchin g machines at present in use.

For full comprehension, however, of myinvention reference must be had to the annexed drawings, formin ga part of this specification, in which like symbols indicate corresponding parts, and wherein- 4o Figure l is a front elevation of the head of a machine constructed according-to my in' of the readily-removable Work-table; Fig. 6, 5o

Fig. 9 is a detail side elevation of the needle-operating mechanism, with the actuating-cam thereof in section. Fig. lO is a detail side elevation of the thread-case, 6o thread-hook, retainer, thread-carrier, and the operating-cams and intermediate connections of the thread-hook and retainer and part of the operating means of the carrier. Fig. l1 is a detail side elevation of another part of the means for operating the thread-carrier; Fig. l2, an enlarged transverse vertical sectional view taken on line Z Z, Fig. 8. Fig. 13 is a detail side elevation, partly in section, of the carrying end of the presser-foot lever; 7o and Fig. 14:, a transverse vertical sectional view thereof. f

The pedestal a of the machine is preferably of the type common to boot and shoe Wax-thread sewing-machines, except that it has an upper adjustable portion or neck a' of` less diameter than the pedestal-body and movable vertically through the openings in the top end of the latter. This movable neck a' carries the head portion of the machine, to 8o be presently described, and also has bolted to it near its lower end a work-support, preferably in the form of a hollow horn a4, the p front side of the pedestal-body ct being slitted from its top end downward sufficient-ly to accommodate'such horn,which projects through it, and as a means for securing the adjustment of these parts relatively tothe pedestal a vertical screw a5 is threaded through a bracket-arm a6, projecting from the face of 9o the pedestal-body a, and has its'upper end bearing beneath the base of the horn, while its lower end is provided with an aperture to receive the end of any suitable bar whereby it can be rotated.

The reason for making the machine-head and work-support adjustable is to accommodate operators who in some cases are incon- Venienced one way or another by the fixed height of machines of this type.

The usual running-gear and attachments are, as heretofore, situated at the base of the pedestal; but as they form no part of my invention they need neither be shown nor further alluded to.

The framing of the head portion of the machine comprises a base-plate l), having openings down through the center to communicate with the interior of the pedestal,aud lateral extensions b', (only one of which is shown,) this base being screwed to the top of the neck portion d'.

b2 is a vertical and forwaidly-projecting web integral with the base-plate b and having an opening b3 to accommodate the operating-cams and their shaft, and left and right hand standards b4 are bolted to the lateral extensions b b. The web b2 also has formed in one with it an upwardly-projeeting ridge or extension b, extending along its upper edge from its forward end rearward for about half the length of the web and slotted, as at 117, to accommodate an adjustable sliding block forming a part of the mechanism, to be presently described, for regulating the length of stitch. Projections b5 b are also forlned on the upper edge of the web b2, the one, bg, forming a bearing for a spindle forming a part of said stitch-regulating mechanism and the latter, b, serving as a part to which one of the feed-operating levers is pivoted. Near the lower forward end of the web bi a circular transverse opening b1" is formed to allow of the operation of the threadcarrier, as will be hereinafter described, and at right angles to such opening Z110 a second opening bu is formed, extending up from the lower edge of the web, and passing but connecting with the opening bw, as shown in Fig. 9, to allow the operation of and accommodate the needle and needle-segment. The upper forward end of the web b2 is also bored vertically to receive the lower end of a vertical standard c, by which various parts to be hereinafter described are carried.

D is the shaft mounted in the standards I)4 and carrying a driving-pulley D', a disk D2, having cam-grooves c and f cut in its lefthand face and a cam-groove r in its righthand face, a second disk D3, having a camgroove g cut in its face, a third disk D, having cam-groove 7L 7e cut in its face, a fourth disk Dwith cam-grooves m n cut in its face, a ifth disk D, with cam-groove o also cut in its face, and a sixth disk DT, also having a cam-groove p cut in its face.

Looking at the front of the machine and beginning at the right-hand end disk D2, l will proceed throughout the series of disks and describe the several parts operated b v the respective cam-grooves cut in the faces of such disks,starting with cam-groove e for operating the take-up. The form of this groove c is shown in Fig. S, and it receives a roller e, which is axially mounted on the sidcxof avertically-reciprocatiug rod preferably formed in two parts or lengths e2 e3 and adapted to project laterally into said groove. The parts e2 e3 of this rod are connected together through a collar-and-pin connection, such as e", and the upper part c2, which carries the roller e', is forked at its opposite end to bear on either side of a ring carried by the shaft D to steady and keep the rod always in a true vertical position. The lower part e3 of the rod passes down through an opening in the top of the movable neck portion of the pedestal and at its lower end is formed with an eye c6 to allow of its being pivotally connected with the take-up lever c7 in any preferable manner that will allow of ready adjustment.

The take-up lever is of bell-crank form and fulcrumed within the movable neck portion of the pedestal upon a pivot pin or bolt c, secured in the neck portion d.

'lhe long arm of the take-up lever is curved to allow of its working within the horn a and carries a sheave elf on its outer end, and near its inner end, in close proximity to its fulerumpoint, is cast a projection in the form of a rod e, which projects downward to engage with and operate the tension-lever.

The cam-groove f in the disk D2 acts in conjunction with the Cain-groove n in the disk D to operate the, feed mechanism. I will first describe the parts actuated by the groove j". This groove f is of the form shown in Fig. 4 and receives a roller f', carried by the inner end of a lever f2, fulcrumed on the projection b" and having its outer end bent inward beneath and flexibly connected with a secondary lever f3, which is in the form of a straight arm having its inner end pivotally connected with the fulcrum-pin of the lever f2 and its outer end curved concentric with the spindle c, (see Fig. 1,) carried in the front end of the web or frame b2, and the flexible connection between it andthe lever f2 is preferably effected by means of a coiled spring f4, taken around a stud f", projecting from the side of the lever f3 and having one end connected to such lever and the other to the lever f2, preferably by means of a clamping-plate f6, holding the end of the spring securely in a groove eutin the face of the lever f2.

The forward end of the lever f2, as before mentioned, is bent in beneath the leverf, and a lug f7 is preferably formed on the side of the leverfs, up against the under side of which the lever f2 is pressed by the action of the springfl, and such lever f2 operates to impart a vertically-reciprocating movement to a feed device which l will describe subsequently to describing the cam-groove n and parts operated by it, which latter I will now describe.

The cam-groove n is of the form shown in Fig. 3 and acts in conjunction with calngroove f, as before mentioned, for operating the feed, and its particular function is to im- IOO IIO

part the necessary horizontal or lateral reciprocating motion to the feed-dog, which motion in one direction is the feed movement proper thereof.

The groove n receives a roller n' on the inner end of lever n2, which is fulcrumed to a movable block n3, adapted to be adjusted along the slot if in the upwardly-projecting ridge be of the web b2 by means of a rack 112 and pinion 113, the pinion being operated by hand-wheel 114 to impart a sliding movement to the rack, which is rigidly connected to fulcrum-block n3, thereby securin g a diminished or lengthened movement of the outer end of lever n2, according as the fulcrum-block n3 is moved from or to the cam n.

The outer end of the lever n2 is forked to enter between two annular shoulders n10 nu, formed on the lower end of a sleeve 7112, which has a laterally-projecting lug 'm13 at its upper end and is tted loosely on the vertical standard c at the upper forward end of the web b2. q A link nl has one end loosely pivoted to the lug 17,13 and its opposite end to the upper end of a vertical carrier-frame w15 for the feed device, such frame having sleeves nl@ n" at its ends to receive the shank of the feed device and being pivotally connected at its lower end at als to a horizontally-swinging frame '17.19, pivotally connected with the standard c through arms w20 n.21, formed with openings to encircle such standard. This hori- Zontally-swinging frame is to allow of the adjustment or rotation of the feed device to different positions about the nose of the horn in order to secure feed in various directions, as this is sometimes necessary in view of the horn being stationary.

To set the frame n.19 and feed in the required position, a notched disk 'm22 is located above the arm w21 and held rigidly upon the standard c by means of a screw cap or nut m23, forcing it against a shoulder n.24 on such standard. A spring-operated latch is used to engage the notches in the disk m22, and such latch being in the form of a lever w25, fulcrumed at nsand havinga vertical arm adapted to engage the notches in the disk w22 and a horizontal arm adapted to be engaged by a pin projection m26 on a hand-lever n2?, also fulcrumed at 7118, the spring w28 for operating such latch being shown in dotted lines in Fig.

1. The vertical arm of the lever w25 is pro-- vided with a pin projection w29, adapted to come incontact with the frame 17,19 and so limit the outward movement of the lever.

The hand-lever n2? is also used for elevating' crumed on the diminished outer end ofv a block g3 and held in place thereon by means of a nut g4. The inner end of this block, which is perforated, as at g5, is also diminished and screw-threaded to take into a similarly screw-threaded boring in the web b2, as is shown in Fig. 10, and lever g2 carries at its outer end a segmental toothed rack g. The cam-groove h is of the forln shown in Fig. 10 and receives a roller h', carried on a stud-bearin g h2 on the side of a sleeve h3, havving wing-plates h4 cast in one with it and bearing upon the sides of groove h to steady the sleeve and keep roller h from being displaced by the rotation of a sliding rod h5, the diminished or inner end of which carries such sleeve loosely retained thereon by means of screw h6. This sliding rod passes through and is carried in the perforation g5 in the block g3 on the side of web or frame b2, to which the lever g2 is fulcrumed, and through bearing hs, also on the side of the web', and is adapted to receive a reciprocating movement from groove h and a rotary movement from groove g through pinion b9, carried rigidly on the rod h5, segmental toothed rack 96, and lever g2, on which such segmental toothed rack is carried.

The forward end of the rod h5 is bored longitudinally and receives the rear end of the thread-carrier proper in the form of a finger hw, bent, as shown particularly in Figs. 1 and 11, so that its free end will project in front of the thread-case and carry the thread in a hook h11 at its extreme end from the needle to the thread-case.

The cam-groove lo in the disk D4 is of the form shown in Fig. 10 and operates the oscillating thread-hook anda device for preventing any accidental displacement of the threadcase when the oscillating hook is thrown back to release the thread after it has taken it around the case. The groove 7e receives a roller le', carried on the inner end of a lever k2, which is fulcrumed at lesto the web or frame b2 and has its outer end terminatingin a segmental toothed rack 7a4. This rack 7a4 intermeshes with a pinion h5, which is formed in one with and centrally of the side of a circular plate k6, which has a peripheral projection k7, to which is secured the oscillating thread-hook 768, the plate and pinion being centrally bored and mounted upon a studbearing 709 in one end of a bracket-arm ,1510, which is secured at the other end to the web or frame b2 and bent outward and parallel with such web, so as to leave sufficient Space between it and the web for the pinion and plate just mentioned and the thread-case, now to be described.

The case inclosing the upper thread is shown in detail in Figs. 6 and 7, and consists of a shallow cylindrical box 7c, one side or end of which is open and the other and closed side of which has a central boss or pin k12,which is preferably passed through a central opening in such closed side to project IOO IIO.

into the case and carries in grooves formed along its periphery and end a spring-clip 7013, parts of which project beyond the periphery, but are compressible. The head of this pin L12 provides a projection necessary to establish a space between the periphery of the case and the frame of the machine to enable the thread to pass freely around same.

The thread reel or bobbin is formed with two circular side plates 7s, which are connected by a centrally-tubular core 7c, adapted to iit over the pin L12 in the thread-case and be held in placc thereon by frictional contact with the projecting parts of the spring-clip L13, which are compressed by it.

The periphery of the thread-case L is perforated, as at 7tlg, to allow of the passage of the thread tlierethrougl1,and adjacent to such perforation a tension-plate k is arranged, one end of which is riveted to the case and the other end of which is bent inward to bear upon the periphery of the case and formed with a hook 7.113. A slot (not shown) in the periphery of the case extends from the perforation k1" to a point beneath the tension-plate near the hook thereof, and an adjustingscrew k2, passingr through an aperture in the tensionplate and screwed into the periphery of the case, is used to regulate the pressure of such plate.

The cam-groove m in the disk D5 is of the form shown in Fig. 3 and used to operate the parts for raising and lowering the presserfoot. The groove receives a roller nr, carried on the end of a lever m2, fulcruined at mS to the web b2 and having a lateral projection m4 on one side. This lever has a flexible connection with a secondary lever m, which I will now describe. The secondary lever m5 is curved somewhat and fulcrumed centrally of its length at the saine point m3 on the web as the lever m2, its inner or rear end carrying a screw m, with which one end of a retractile coiled spring m7 (which is shown partly broken away) is connected, its other end being connected by means of a screw m8 to a device for adjusting the tension of such spring, consisting of a screwbolt m, taking in a screw-threaded boring in the web b2, such bolt carrying loosely thereon block m10, which also carries a guide-rod m11, sliding vertically through a second bearing in the web. The purpose of this flexible connection between the two levers m2 and m5 is to allow the lever m5 a certain amount of independent play or automatic adjustment, as is required by the variations in the elevation of the presser-foot caused by the varying thickness ot' the stock being operated upon. The lateral projection m on lever m2 serves to maintain levers m2 m5 in their proper relative position. The presser-foot 38 is carried ad justably with relation to the work by a swiveling block m12 in the outer end of such lever mi and held in place in such block by set-screw m13.

mi is an adjustable guide for thc upper end or shank portion of the presser-foot, and is in the form of a curved arm slotted and held to the web b2 by a set-screw m15.

The cam-groove o in the disk D6 is of the form shown in Fig. 9 and used to operate the needle. The groove receives a roller o on the inner end of a connecting-rod o2, having its outer end pivotally connected at o3 with the needle-segment o4, which is held in place in its guideway by suitable retaining-plates o5, as shown in Fig. 9, and carries the curved needle o6.

The cani-groove p in the disk D7 is ol' the form shown in dotted lines in Fig. 8 and receives a roller adapted to project into said groove and axially mounted on the side of the upper end of a vertically-reciprocating rod p3. rlhis rod may be made in two parts, and such parts may be connected together in a similar manner to the parts c2 e3 of the take-up rod,and the upper part, which carries the roller, (like the part 62,) may be forked at its upper end. The lower part p3 of the rod passes down through the top of the movable neck poi-tion of the pedestal and at its lower end is formed with an elongated eye p6 to allow of its being adjust-ably and pivotally connected with one arm of a lever p7, fulcrumed on a rod p8, which is shown in detail in Fig. 12, and carries the tension-wheel and its operatingspring, as will be hereinafter described. The other arm of this lever p7 is pivotally connected to the lower end of a reciprocating bar or section p, slotted, as at p10, to receive a block p, pivotally carried upon a pin p12 within the horn and with which block said bar or section through slot p10 has a sliding connection. The upper end of this section p" carries the threader portion proper. This threader portion proper, as will be seen by reference to Fig. S, consists of a pair of springfingers p13 p14, carried in the upper end of the bar pf and secured therein by set-screws p20, by the loosening of which the fingers can be adjusted higher or lower, as may be desired, with relation to the needle. The upper free end of each finger is formed one (13) with an eye p16 and the other with a hook p17, the eye and hook being for the purpose of placing the thread in the barb of the needle, the chock p17 allowing of the withdrawal of the thread by the needle. As a means for adjusting or locating the threader relatively to the needle, adjusting-screws p18 are carried by the sides of the horn, as shown in dotted lines in Fig. S, and adapted to bear loosely upon either side of the bar p9 Without in any Way interfering with its motion.

The thread-tension device which I prefer to use is shown in Fig. 8 and in detail in Fig. 12, and consists of a sheave 70, mounted loosely on the fulcrum-rod psof the threaderlever before mentioned and having two peripheral V-shaped grooves 71 72, the former ot' which receives the thread and the latter of which presents two friction-faces fora friction-lever '73, presently to be described, to

IOO

IIS

bear upon. Acting upon this sheave is a flanged' sleeve 7 a, loosely mounted on said rod p8 and forced against one side of the web of such sheave by means of a coiled spring 7b, encircling the rod and having one end bearing against the sleeve 7 and the otherend against the hub of an adjusting hand-wheel 7, screw-threaded on the outer end of such rod, the pressure of the sleeve 7 upon the sheave 70 serving to force it in turn against a sleeve 7d similar to the one 7rt but rigidlyT mounted on the rod 198.

The lever 73 has one end fulcrumed at 74 in the base of the work support or horn at a point below the sheave 70 and its opposite end flexibly connected with the pedestal by a coiled spring 75. 76 is a lateral shoe projecting from its upper side, with its edge shaped to conform to the groove 72 in the sheave 70.

The lever 73 requires to be furnished with a rise or projection of some sort to be acted upon by the downwardly-projecting oscillating finger en, and in order that the action of the lever 73 can be varied and the extent to which the thread from the thread case is drawn through the work regulated I prefer to make such rise or projection in the form of an adjustable block-nut 77, fitting over and having a screw-threaded connection with the lever and formed with a lateral extension 7 8, such nut or block being movable along the lever in either direction.

Thus far I have described all the parts of the machine which are common to and which operate the immediate parts, tools, or instrumentalities that act directly upon the work and beinginterchangeable, as may be desired, for various kinds or characters of work-such as the McKay stitch turned-shoe sewing, the stitching of welted work, edge-stitching,

and plain straight sewing-and I will proceed to describe the particular instrumentalities necessary to do edge stitching or plain straight sewing.

The novel instrumentalities or tools comprised in the present invention and to be combined with the common parts just mentioned are adapted to be readily removable and are preferably constructed as follows:

The presser-foot (shown in detail in Fig. 4) consists of a shank or bar 38, having a narrowed and flattened foot portion 39,' notched, as at 39, to allow of portions of such foot portion being situated in close proximity to the needle and on opposite sides of same, while a groove 4S is formed along its under side to accommodate the stitching beneath it, and so avoid any chance of flattening such stitching. The foot portion 39 is tapered in order that it may bear over the stitches and at the same time be raised and lowered while the sole is being stitched without interfering with either the upper or the stitches.

The work-table (shown in detail in Fig. 5)

consists of a plate 32, the dimensions of which will depend upon the manner in which the work is held while being stitched-as, for instance, if the boot or shoe to be operated upon is held with the tread of the shoe thereof uppermost the forwardly-projecting portion 32a' of the table will have to be shortened, so as to accommodate the upper of the boot or shoe, and at the same time act as a work-guide, as shown in dotted lines in Figs. 2 and 5. I prefer, however, to hold the boot or shoe to be stitched with the tread of the sole thereof downward, as shown in full lines in Fig. 2, in which case either the side of the foot portion 39 of the presser-foot will act as a work-guide, or a readily-removable work-guide, to be hereinafter described, can be provided, and the work-table 32 can be considerably enlarged, as shown in Fig. 5, for a purpose to be hereinat'ter set forth. The work-table is preferably secured over the open nose of the horn t4 by means of a web 52, extending downwardly over the lefthand side of the nose of the horn, to be attached thereto by screws 52, An opening 52b is cut through the plate 32 to accommodate the needle oG and the perforating-awl 55.

The adjustable readily-removable stationary work-guide that I preferl to use, if it is desirable to keep the work from touching the presser-foot, consists of a plate 60, slotted, as at 6l, to receive a retaining-screw 62, which takes into the work-table 32, the bearing edge of this guide being offset or bent upward and outward, as at 63, to provide a spaceto accommodate the edge of the sole and allow the forwardly-projecting portion of the guide to bear upon the upper of the boot or shoe.

The awl is operated by groove r in the opposite side of disk D2 to that in which grooves g and f are cut. This awl 55 when edgestitching is being done must project out of its segment a sufficient distance to allow it to pass through the work, which is readily done by loosening the retaining-plate and drawing the awl out the required distance.

The operation of the present embodiment of my invention is briefly as follows: The feed-dog 27 is first raised by handle n2? and the boot or shoe placed upon the work-table with the upper bearing preferably against the forwardly-projecting portion 63 of workguide 60. The feed-dog 27 is then lowered by handlen2 and holds the work against displacement until the presser-foot relieves it. Upon the machine being started the awl or perforator 55 will bepassed through the work a sufficient distance to project upward a short distance in front of the end of feed-dog 27 to allow such feed-dog to bear against the end Vof such awl or perforator in order that the work can be fed by such feed-dog without the necessity of its being inserted into the work, thereby besides affording a firm hold upon the work to be fed will at the same time not disflgure the surface of such work. The work is then fedv by such feed-dog 27, the awl at the same time being caused to ac- IOO IIO

companyit. The rest of the operation is precisely the same as that described in my allowed application, Serial No. 677,246, in that the presserfoot is lowered, the awl withdrawn, the needle inserted, the threader threads the needle, the needle draws the thread through the work, and the threadcarrier engages the thread and conveys it to a position to be taken by the oscillating hook partially around the thread-case, after which it is acted upon by the take-up and tension devices to tighten and complete the stitch, the presser-foot being then raised, and the operation either repeated or, if the stitching of the edge of the boot or shoe is completed, to allow it to be removed, to do which the feed-dog 27 will have to be first raised by handle n.27.

As will be seen from the foregoing, a machine for doing edge-stitching constructed according to my present invention besides having the advantage of a comparatively small number of operating parts to make a twothread lock-stitch, will allow an operator to stitch the edge of the sole of a boot or shoe with eitherside uppermost, and, further, it is only because I illustrate and describe this form of machine as converted from a machine for doing McKay7 style of work that an unnecessary space is shown between the stitch-forming instrumentalities and the pedestal; but this unnecessary space can be readily diminished by any one skilled in the manufacture of sewing-machines by shortening the levers and rods, thus strengthening such levers and rods and increasing the speed of the machine without departing from thespirit of my invention.

It is also obvious that by using the worktablc of extended width and length herein described and illustrated and shown in detail in Fig. 5 plain straight sewingsuch as sewing-belting, harness, or the like-can be done as readily as edge stitching. Finer work, such as the stitching of uppers, can be done equally well by simply dispensing with the awl or perforator and preferably the adjustable work-guide, which are readily removable, or the forked rod am can be removed by loosening its retaining-screw and the feed-dog 27 lowered to engage the work, in which case the awl will simply be inserted and withdrawn from the work and will not assist in operation of feeding, which will then be done entirely by the feed-dog 27. I find the swinging feed desirable in instances where the work cannot readily be turned, although in most instances it will not be required.

Vhat I claim is as follows:
