SPECIFICATION forming part of Letters Patent No. 444,126, dated January 6, 1891.

Application filed December 18, 1889- Serial No. 334,163. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM CAREY, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have in- 5 Vented certain new and useful Improvements in Machines for Uniting the Soles and Uppers of Boots and Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to that class of ma chines principally used for securing together thcsoles and uppers of boots and shoes by a seam composed of. a continuous thread or Wire in loops and short lengths of wire or other like material inserted in same.

The objects of the invention are to provide means for producing a union which shall not require a complete perforation of the two or more substances or parts to be secured, to

avoid the necessity of preparing'the short lengths of wire in any way, such as bending, &c., previous to their insertion, and to do away with the necessity of turning the boot or shoe inside outand of channeling the sole.

- The distinguishing features of the invention are, first, a loop-inserter and an awl, or, as it might be otherwise termed, a combined awl and nail-driver, arranged to work at right angles to each other, the former forcing 0 the continuous thread or wire in loops entirely through one or more of the pieces being secured and partially through the remaining piece, and the awl serving to drive from the edge of the latter piece inward the short lengths of wire fed into the machine and to locate them within the loops of the continuous thread,so asto form a locking-toggle; secondly, the adaptation of the well-known swinging horn of boot and shoe machinery to this class of machines to carry the articles to be united; thirdly, an arrangement of parts allowing the uniting of substances of varying thicknesses, and, fourthly, means for severing the continuous thread in a sense automatically when the work is completed, and so allowing the article to be removed from the horn freely. Such mechanism I will now describe in detail, and for full comprehension of the same reference must be had to the annexed drawings, in which Figure 1 is a front view of the machine, showing the swinging horn in a central position; Fig. 2, a part vertical elevation and sectional view of same, taken at right angles to Fig. 1; Figs. 3, 4, and 5, detail views of the nose of the horn and mechanism arranged therein for introducing the continuousthread; Fig. 6, a horizontal section of machine on line x a, Fig. 2; Fig. 7, a horizontal section on line at 00, Fig. 3, looking up, showing cutting device; Fig. 8, a detail perspective View of loopinserter; Fig. 9, a detail front view of goosehead and upper portion of body of machine;- Fig. 10, a part vertical elevation and sectional View of same at right angles to Fig. 9; Fig. 11, a section on line m 00, Fig. 10; Figs. 12, 13, 14:, 15, 16, 1'7, 18, and 19, sections, respectively, on lines 1, 2, 3, 4, 5, 6, '7, and 8, Fig. 10; Figs.

Figs. 28 and 29 are detail perspective views of the cutter for severing the wire when work is completed.

Similar letters of reference indicate like parts. i

A is the main frame of the machine in the form of a hollow tapering pedestal or column having an extension A, with an opening A in it, and arm A extending from its front, also carrying on its upper end a top plate a, 0 perforated to accommodate a vertical shaft and carrying a head-section A, also perforated to form a bearing for the vertical shaft and cut away to accommodate cams on the same, and terminating in a goose-head A 5 which is in line with the extension A and arm A B is the horn, hollow, and provided with a vertical sleeve B, projecting from the inner end of its horizontal portion down through the upper part of the extension A, which forms a bearing for it, and has screwed upon its end a collar 13 to prevent vertical movement. To insure a steady vertical, alignment throughout the sidcwise rotation or swinging movement of the horn, an arm 13 from the upper side of its horizontal portion is pivoted to the arm A in the axial line (indicated in Fig. 2) of the sleeve 13. In the nose of the horn is arranged the loop-inserter, and this,

-with the presser-foot carried by the goosehead A", works vertically in the axial line of the sleeve 13, the presser-foot offering the necessary resistance to the action of the loopinserter and awl, and in this respect fulfilling a function of the usual work-table.

U is the loop'inserter, (shown in detail in Fig. 8,) flat in cross-section, grooved at its upper end and partially down the side edges to carry the continuous thread of uniting material, and having a screwed lower portion for insertion into the screwed eye of a movable cross-head C, working in vertical guides G on the inner sides of the nose of the horn. (Shown in Figs. 3 and 4.) Vertical reciprocating movement is imparted to this crosshead C preferably by cam mechanism, together with a vertical sliding bar extending vertically across the opening A in the extension of the frame, working in the sleeve 3 of the horn, and a guide in the lower part of such extension, a screw in such bar, all to be more fully described, and bell-crank levers D and E, a geared segment D, and connecting-rods D D, these latter arranged within the horn and connected as shown in Fig. 2.

Fig. 3 is a section taken through portions of two substances, (in the present case,) resting on the nose of the horn and also through such horn on the line of the union, the view being in the direction indicated by the arrow in Fig. 4, and as it is necessary for the loopinserter "I, not being round, but flat, to be kept always in a line at right angles to the forward movement of the awl whatever may be the position of the horn, (which rigl'it-angle line will be as indicated by the dotted line, Fig. 5,) the mechanism hereinafter described is used to retain the loop-inserter in such position.

The upper surface of the nose of the horn is composed of a plate Z), conforming to the usual contour of such nose, screwed in place and having two circular openings, whose axes are in line with the longitudinal axis of the horn, with interior annular recesses in the plate encircling them, in which fit, so that their exteriors will be flush with the exterior of the p1ate,two geared disks 1) b the former having a central slot parallel with the dotted line shown in Fig. 5, up into which the end of the loop-inserter 0 projects, and through which it works to drive the continuous thread I) in a loop into the substances, as shown in Fig. 3, and an eye Z) in the same line as the slot through which the thread is drawn, and b having on its interior face radial teeth I), with which meshes a bevel-pinion on the end of a shaft 71", running down the horn, and by means of another shaft and other gears b I) b I), so as to communicate with an annular rack I) on the extension A encircling the sleeve 13 of the horn. These disks are held in place simply by confinement between the plate I) and the body of the horn, and are in mesh with each other and free to be rotated in such bearing. 13y such means and the screw-connection of the awl with the crosshead C the loop-inserter, whether the horn be turned to right or left, will not turn,as the gear I), being rotated by traveling along the rack 71, transmits motion through the system of shafts and gears to give a rotation to the gear 11 opposite to that of the nose of the horn, and so counteracts any rotation that I) would have with it and the cross-head C,thc eye of this latter simply working on the screw, which is of very low pitch, as shown in Fig. 8, of the loop-inserter, and so allowing it to remain substantially in the same position.

If is the cutter for severing the continuous thread when the work is completed, as shown in Figs. 4, 7, 2S, and 29, and consists of a plate with inwardly-projecting knife-edge 71"", held in place in a recess to receive it in the vertical end of the nose of the horn by a screwb passing through the same. The knife-edge lits close up to the bottom of the disk Z1 and projects inward sufficient to shear past the eye 0 in it, and so cut the wire extending from same when the horn is swung beyond its usual half-circle, as indicated by dotted lines, Fig. 7.

The mechanism for adjusting the length of throw of the loop-inscrter C will be better understood after the parts connected with the awl and presser'foot mechanism have been described.

In an oblong recess (L in the top plate a (see Figs. 10 and 12) is arranged a slide F, corresponding in shape and depth to the recess, so as to be flush with the top plate, but shorter in length, and having a central opening for cams, mounted on the vertical shaft referred to and to be hereinafter described, to work in. To this slide toward the rear is pivoted the section G of a hinged carrier formed of two sections G G, i being the hinge-pin. The head-section A of the machine is cut away at its base and front to accommodate the section G of this carrier, which is also formed with an opening to accommodate cams on the vertical shaft and projects out through the front of such head-section toward the nose of the horn, and is normally held in an inclined position, for reasons to be mentioned farther on,with its nose higherthan the top ot'such horn, such position being determined by the lower end of a vertical pin G (with which the carrier makes contact, as will be more fully explained,) socketed in a channel in the web of the head-section and adjusted by means of a cam-lever G, pivoted above it, and by a spring-support G",socketed in the top plate a near the front, holding the ITO carrier up, as shown in Figs. 10 and 27. The awl H of'the machine is arranged in this carrier, and, as shown in Figs. 13, 14, 15, and 20, is secured by screw h in a cross-head H, located in a longitudinal slot G in the forward end of carrier G and adapted to receive a reciprocating motion from mechanism to be hereinafter described. The nose of carrier is perforated, as shown at g, Fig. 14, for the passage of the awl, and in a groove g at right angles to this perforation a slide J, with two channels jj parallel with the perforation, is arranged to work and serve to cut the short lengths of wire to be inserted by the awl H from a continuous strand fed into channel j from feeding mechanism at certain intervals through another channel to be described, and also to locate them in a position in front of the awl, as will be explained in the operation of the machine. v

K K are two horizontal disks with serrated peripheral grooves, as shown in Fig. 20, for feeding the continuous strand from which the short strips It, as shown in Fig. 14, are out into the channel 70 in the interior of the forward end of the carrier and leading to channelj of the slide J. The channel k and recesses for the disks K K are formed in the upper surface of a portion G of the carrier about half its thickness, (see Fig. 20,) and by means of plates k k the carrier is evened up to the full thickness. This construction is also convenient for providing the proper dovetail guideways for the cross-head H. The disk K is keyed on a spindle 70, passing completely through the carrier and having mounted on its upper end a ratchet K, to be operated as will be described farther on, and K is pivoted in the free end of a spring-holder 70 screwed to the side of the carrier, by which the necessary friction is secured for feeding various sizes of wire and compensating for any wear.

Referring now to Figs. 9, 10, 11, and 17, L is the presser-foot bar, secured in place in a vertical channel in the goose-head A? by faceplate a having slot a and adapted to work vertically in such head above and in line with the loop-inserter O.

L indicates a longitudinal slot in the central portion of bar L, in which slot is fitted so as to be adjustable in it a slide L This slide has a slot Z, into which project the ends of the operating-lever L and an adjusting wedge-piece M, to be more particularly described, and has the lower end of a vertical adjusting-screw L working through the upper portion of the bar L, connected with its upper end, as shown in Fig. 10, whereby it is moved up or down to accommodate exceptional thicknesses of material, and another vertical adjusting-screw L is arranged to work in a bracket Z, projecting from the back side of bar L in a line over the forward end of carrier G and come in contact with same for purposes to be mentioned farther on.

In a horizontal dovetail groove in the web of the head-section, about level with the slot Zin slide L when the presser-foot is in its raised position, as in Fig. 10, is arranged to work a slide M, to the forward end of which the wedge-piece M is pivoted at m. This slide is hollowed almost from end to end to accommodate a coiled expansion-spring m, as shown in Fig. 17, one end of which is secured to a fixed stud m passed through an aperture m in the face of the slide, and a slot on in the back of same and screwed into the web of the frame beyond, and the other end bears against the interior of the inner end of the slide, so as to keep a bearing-surface h projecting at right angles thereto, pressed against an operating-cam to be presently described with several others. A rack M is formed on the face of the slide for abouthalf its length from the rear end, with which meshes a pinion M mounted on a vertical shaft M extending from a bearing in top of the head-section down through apertures m in the carrier G, slide F, and top plate a to and through the bearing m situated in the interior of the pedestal A about level with the collar on the end of sleeve B of the horn, and on its lower end is fixed an arm M.

D is the vertical sliding bar previously mentioned in relation to the loop-inserter 0, having its upper portion, which works in the sleeve B of the horn, hollow and screw-threaded to receive the screw M provided with a head m and neck m projecting above the top of the bar, the latter, as shown in Fig. 26, being partially encircled loosely by the collar-segments E, pivoted to the ends of the forked bell-crank lever E, pivoted in the horn. A screw-pin m projecting from the screw M near its lower end, is connected with the arm M on the shaft M by a rod M and the adjustin g mechanism of the presser-bar is there by connected with that of the vertical awl and a unison of operation, to be described, effected.

It now remains to explain the mechanism for operating the parts just described and the complete operation of the machine.

N is the driving-shaft, carried in suitable bearings horizon tally through the frame A at a height which brings its front end opposite the center of the opening A and having mounted on its rear end the driving-pulley, on its front a disk 0 for operating the vertical awl, and having a cam-shaped groove 0 in its face, in which fits a roller 0 carried by sliding bar D, and about midway a bevelgear N, intermeshing with a similar one N on the end of a vertical counter-shaft N extending up through a lower bearing N in the pedestal to an upper one formed in the top of the head-section A Pis a cam-roller (for operating the awl) keyed on shaft N just below top plate or, having a peripheral groove p on it, containing a high rise p and alower rise 19 On a spindle P, carried in projections from the front of the pedestal, is mounted a bellc 'ank lever P with one arm projectinghorizontally through a slot I in the pedestal and carrying at its end a roller P to fit the groove 1) in such cam-roller P, and its other arm extending vertically up toward the carrier G and having socketed in its end (so as to allow for certain lateral play of such carrier, as will be fully explained) the neck of a headpiece P, with which the cross-head II is connected by a link P pivoted to the downwardly-projectinglugs of such cross-head and to such head-piece.

Proceeding upward, the first Q of a series of cams above the top plate on the shaft N is for giving abackward throw to the slide F, its contour being shown in Fig. 16 above the slide F, one R of the shape shown in Fig. 12 for giving it a forward movement, and upon these in succession, one S (shown in horizontal section in Fig. 13) required to move the carrier G laterally, and another T (shown in horizontal section in Fig. 14-) for operating the slide J, which cuts the small pieces of wire from the continuous strand and feeds them to the awl, and then the one U that operates the feed for such continuous strand. Above these again is situated a cam-rollerV, having a peripheral groove V in it containing arise V for operating the presser-foot bar, whose lever L pivoted at l to the web of the headsection, carries on its inner end a roller L which fits such groove. The uppermost cam \V is that which operates the slide M, to which wedge-piece M is attached,its horizontal section being shown in Fig. 17.

The description of the intermediate connections between the parts first described and those just referred to will be better given in the explanation of the working of the machine and the adjustment of its several parts for accommodating varying sizes of material, with which explanation I will therefore now proceed.

In order that a complete conception of the machine may be had and of the size of the stock or material it is capable of accommodating, it may be as well to say that Fig. 10 is drawn to a scale approximately half full size, and that the two substances indicated on the horn would therefore be about a medium size of the stock in the class to which the particular work of this kind of machine is applicable. Before either the loop-inserter or the awl is inserted into such material it is necessary for the presser-foot to come down on top of and the nose of carrier G to be in contact with the edge of said material, as indicated by dotted lines, Fig. 10, and after the stitch has been completed to feed the same forward.

To allow the stock to be placed on the horn conveniently, the cam-lever G, which when depressed acts to keep the carrier G at the maximum elevation required for the largest thicknesses of material, is turned up and the nose of the carrier G raised by the action of spring-support G to the height shown by dotted lines, Fig. 27, so as to leave plentyof space between both noses.

To accommodate a less or greater projection of the edge of the material beyond the nose of the horn, the forward throw of the carrier G must be regulated by hand before the machine is started, as will now be explai ned, reference being had to Figs. 12 and 22.

In the front portion of the slide F, to which slide the carrier is pivoted, is a dovetail section F, against the inner end of which cam R works, whose near approach to or recedence from such cam will cause a greater or less forward throw of the carrier, the screw F whose head projects through a perforation in the front of the top plate. being the means for securing the necessary adjustment, and that adjustment (shown in Fig. 12) being what is required by a medium projection of the ma terial, the slide being moved only half-way toward the cam. For greater or less vertical thickness of material there must be an aceommodating and corresponding variation in the depression of the presscr-foot, the ele vation of the carrier G, in which the awl is carried and themovement of the loop-inserter, in order that the two implements willalways work in the required relation to each other, and to effect this the adjusting mechanism embracing the wedge-piece M, screw L, rackslide M, pinion M vertical shaft M and screw M with connections between them, is used.

The maximum height at which the horizontal awl may work is shown by the inclination of the carrier in Figs. 10 and 27, (secured by spring-support G and cam-lever G, as before n1entioned,) which is its normal position after the work is placed on the horn, and in order that the awl may be inserted at lower points the adj usting-screw L is used to depress the carrier when the presser-foot bar is brought down. In the present case, as medium-sized stock is shown in place, it will be necessary to depress the carrier to the position indicated by dotted lines in Fig. 10, and if the stuff were thinner the screw L would be lowered accordingly and if thicker raised to suit.

Everything is now in readiness to start, and in order that the relative operation of the several parts may be thoroughly understood it will be well to divide a single rotation of the horizontal and vertical shafts of like speed into the sixteen degrees of movement indicated by radial dashes wherever the shafts show in section and extended at different points when required. The rotation of the shafts is in the direction indicated by the arrows, and the first degree of movement will, as shown in Fig. 13, allow the projection s on the end of the curved levers, pivoted at s to the slide F, to be pressed into the recess in the cam S by means of a springpin S located horizontally in the base of the headsection, and by means of a nut S pivoted vertically on the opposite end of such lever and working in a slot S in the carrier enable the lever to throw such carrier sidewise in the direction indicated by arrow 1 to the position shown by dotted lines, which is determined by the adjusting-screw S working horizontally in the base of the head-section and arresting the throw of the carrier. It is by means of this screw S and a similar one S", arranged in like manner opposite it in the base, that the feed of the material on the horn to secure a long or short space between each locking-toggle is regulated, as will be more fully explained. Two degrees of rotation, as seen in Fig. 12, will enable cam R to throw slide F forward in the direction of arrow 2, and with it carrier G, by the rise of such cam coming in contact with the projecting inner end of the section F of such slide to the position shown by dotted lines in Figs. 12 and 10-6. 9., into contact with the edge of the material on the horn. Three degrees will, by means of the rise of cam T, (shown in Fig. 14,) throw the forked end of a lever T, pivoted at t to carrier G, into the position shown by dotted lines, and the opposite geared end of this lever in mesh with teeth on an end of another lever T also pivoted to the carrier, will cause the opposite forked end of this latter lever, in which works a pin 25, projecting up from slide J, to move such slide into a position that brings its channels j 3'. respectively, in line with the channel k (through which the wire to be out into short pieces is fed) and the perforation g, (through which awl H works.) From three to five degrees, by means of the rise of cam U, (shown in Fig. 15,) will move the forked end ofa lever U, pivoted at a to the carrier, to the dotted position shown, and the spring-bolt U projecting from the opposite end of same in contact with ratchet K, will rotate same a single step and cause disk K to feed the strand of wire held between it and K along channel K into channel j in the slide J. Almost simultaneously with this feed and during the fifth degree of rotation the rise of cam S comes in contact with the end of lever S and presses it back to its original position, thus throwing the carrier in the direction of arrow 3 and so feeding the stock a step, the nose of the carrier being serrated to afford a grip. In connection with this feeding movement of the carrier, it will be obvious that by adjusting the screw S nearer to or farther from the side of the carrier the length of the spaces between each locking-toggle can be shortened or lengthened, the opposite screw S serving to always arrest the return movement of the table at the same point with relation to the hornviz., with the axis of the horizontal awl in line with that of the vertical one. Half a degree more will, through the rise V in the peripheral groove of camroller V, elevate the end of lever L carrying roller L and depress the forward end of same, which enters the slot 1 in the adj ustableportion of the presser-foot ba A quarter of a degrees rotation beyond this will be sufficient to free the slide M from the rise of cam \V, (shown in Fig. 17,) which has from the start of the machine been pressing it forward until the bearing-section of the wedge-piece has its narrower portion situated between the forward downward bearing-point of the lever L and the bottom edge of the slot Z, as shown by dotted lines, Fig. 10, at which moment the slide becomes subject to the action of the spring m within it, whose force will throw it backward to a distance dependent upon the thickness of the material under operation on the horn, as will be seen from the following: As the lever L has an invariable throw of, say, three-eighths of an inch, and it is required that the presser-foot be depressible for distances varying from three-eighths of an inch to reach the thickest to five-eighths for the thinnest stuff, this difference of two-eighths must be made up by the forcing of the wedge when the thinnest material is in place in between the points mentionedviz., the bearing-point of the lever and the bottom edge of the slot. As will be easily seen, any such adjustment as has been described in connection with the awl and presser-foot must necessitate a corresponding adjustment in the throw of the loop-inserter, and this is secured by transmitting the variation through the rack M pinion M shaft M and arm M to the screw M located in the sliding bar 1).

Before explaining the particular operation of screw M it will be best to point out that the sliding bar D has an invariable vertical throw, or, to be more exact, a vertical drop, as it is by the falling of the roller 0 carried by it, into the fall in the groove 0 in the face of disk 0 (shown in Fig. 25) and the consequent downward movement of the bar that the upward movement of the loop-inserter is effected. This vertical movement of the loop-inserter will take place on the sixth degree of rotation of the shafts, the position of the sliding bar D, and the intermediate connections between it, and the loop-inserter being in the meantime in the positions shown by Figs. 4c and 23. It will be noticed that the horizontal arms of bell-crank lever E in Fig. 23 are thrown upward by the top of the sliding bar bearing against the under side of the collar-segments E, and that the head of the screw which is required to depress such horizontal arms of the lever E is outof contact with and some distance above same, which distance corresponds'in effect to the two-eighths difference mentioned in connectionwith the depression of the presser-foot bar. Now before the rise of the loop-inserter takes place the proper adjustment is oommunicated to the screw M through the means mentioned, and this consists in diminishing the distance between the head of the screw and the collar-segments of the lever E by ro tatingthe screw in one direction and so lowering it as the material may become thicker and a long throw of the loop-inserter C be required, as it will easilybe seen that if during the downward movement of bar I) an y portion of such motion is lost to the lever E, as will be the case in uniting the thinnest material, the loop-inserter cannot possibly be raised as high as when the head of l) is in contact with the lever E before it starts to descend. The rotation between the seventh and eleventh degrees will, through the high rise p in the peripheral groove 1) of cam-roller l, acting on the end of lever P carrying roller P", cause the vertical arm of such lever to be thrown forward the distance indicated by axial line 1, and so drive the cross-head ll forward and the awl through the loop of the stitch that has been formed by the loopinserter and withdrawit. The eleventh degree will cause cam T to throw slide J back to its original position, with channely' in line with perforation g, and by so doing sever the length of wire that has been fed into ehannelj, and so locate it in the path of the awl which, between the thirteenth and fifteenth degrees of rotation, is, by means of the lower rise p of cam'roller throwing the vertical. arm of lever P the distance indicated by axial line 2, caused to drive forward the piece of wire in front of it and locate it in the loop, thus locking the loop. The last degree of rotation will cause the rise of cam Q to come in contact with the rise Q on the face of the circular opening in slide F, as shown in Fig. lb, and thus return the same and the carrier G with it to its original position, thus com 'iletingan entire operation.
