SHOE-LACING MACHINE.

SPECFIGATION forming part of Letters :Patent No. 692,956, dated February 11, 19042.

Application filed April 30, 1900. Serial No. 15,019. (No model.)

To @ZZ whom, it 77mg/ concern:

Be it known that I, DANIEL AARON WIL- LIAMSON, a citizen of theUnited States, residing at Tyrone, in the county of Blair and State of Pennsylvania, have invented a new and useful Lacing-Ma'chine, of which the following is a specication.

This invention relates to a shoe-upper-lacing machine; and the objectof the same is to provide simple and effective mechanism for regularly threading a shoe-lace through the eyelets of an upper in a uniform and regular mannerprevious to lasting the said upper and to overcome the disadvantages arising from hand-lacing and preserve the uniformity of different sizes of shoes after completion and permit the same to be closely' laced when worn and have a regular dimension at the location of the instep without defacing the edges of the upper adjacent the eyelets or tearing out the latter during the lasting strain.

The invention consists in the construction, arrangement, and general and detail combination of parts which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of an upper-lacing machine embodying the features of the invention. Fig. 2 is a top plan view of the improved machine with the arm broken away. Fig. '3 is a front end elevation of the same. Fig. 4 is a horizontal section taken in the plane of the line 4 4, Fig. 1. Fig. 5 is a detail perspective view of the upperholding clamp and a part carried thereby. Fig. 6 isa bottom plan viewof the loop-frame which is carried by the clamp. Fig. 7 is a detail elevation of one of the actuating cams and gears. Fig. 8 is a perspective View of the improved lacing-machine, showing the shoe-upper in applied position thereon. Fig. 9 is a plan view of a portion of the shoe-upper, showing the lacing as it appears on one side after insertion. Fig. 10 is a similar view of aportion of the shoe-upper looking toward the opposite side of the saine. Figsr 1l, 12, 13, and 14 are diagrammatic views illustrating the manner ot' inserting the lace in the upper.

Similar numerals of reference are employed `to indicate corresponding parts inthe several of such dimension and contour as to partially house and afford convenient means for mounting the several mechanisms supported thereby, and from the rear thereof the Vertical member 2 of an arm 3 rises to a desired height and continues into the horizontal member 4 of said arm, from which project upper and lower bearing extensions 5 and 6, the eXtension 5 being constructed with an angular bearing-plate 7 and the extension 6 itself being disposed horizontally under the plate '7 and both suitably apertured for the vertical reciprocation therethrough of a needl-e-bar 8, having a threading-needle 9 clamped in the lower extremity thereof. To one side of the arm 3 an oscillating lever 10 is pivotally connected, the fulcrum being located nearer the rear end, and' thus increasing the throw of the portion of the leverin advance of said fulcrum or toward the front end of the machine, as will be readily understood, and to the rear end of said lever, beyond the fulcrum, a connecting-stud 11 is secured and engaged by the upper slottedend 12 of a vertical pitman 13, having an eccentric connection 14 at its lower extremity, with the drive-shaftl eX- tending transversely through the bed, and having thereon also at one end a grooved drivin g-pulley 1G to receive a belt from a suitable source of power and at the other end a pinion 17 for a purpose which will be presently explained, the pulley 16 and pinion 17 being located on the exterior of the opposite sides of the bed 1. The front end of the lever 10 is also formed with a slot 18 for loose engagement with a pin 19, projecting from the needle-bar S, and by means of the said slot 18 in the lever 10 and the slot 12 in the die-bar move easily and Without binding or without too much lost motion to thereby proper1 y reciprocate the said needle-bar and effectually carry out thelacing of the upper, which will be more fully hereinafter specified.

The pinion 17 meshes with a spur-gear 20, integrally formed with a cam-rim 21 on its inner side, as clearly shown in Fig. 7', and between which and the correspondingly-shaped in eccentric relation to the innenside of said spur-gear. The cam-groove 23 is engaged by a pin 24, having a roller 25 thereon-for antipitman 13 the parts for driving the said nee-4 web 22 a cam-groove 23 is regularly defined IOO frictional purposes, the said pin being secured to a bell-crank lever 26, fulcrumed on the adjacent side of the frame, and to the opposite arm of said bell-crank lever an angularly-bent connecting-rod 27 is secured and eccentrically attached at its opposite extremity to the cross-arm 28 of a segmental oscillating gear 29, pivoted on a horizontal seat 30 at the front end of the machine. The said segmental gear 29 is in continual mesh with a pinion 31, xed in a horizontal position on a whirl-post 32, having a Whirl-head 33 on the upper extremity thereof, with an opening 34 therein, through which the shoe lace or thread is fed, and operates in such manner as to place the thread or lace in the hook 35 at the lower extremity of the needle 9. The pinion 34 and whirlpost 32 have engagement with a front yoke 3G, which is secured to the central reduced portion of the seat 30, adjacent the location of the said whirlpost and pinion, and has its upper horizontal member 37 forming a bearing for the' said post.` The lace or thread,

which is fed from a suitable reel or spool lo-v cated in proper relation to the machine, is passed through the outer looped end of the yoke 36 and then around a tension 38, similar in all respects to an ordinary sewing-machine tension, and from the said tension the thread or lace is led through the opening 34 in the whirl-head 33. It will be obvious that the function of the tension 38 is to take up the slack ot' the thread or lace, and it will also be seen that the employment of the segmental gear 29 and the cam mechanism for operating the same will cause the Whirl-post and whirl-head to be properly rotated and in 'timed relation to the reciprocation of the needle to form the loop and produce a chainstitch. On the drive-shaft l5 acam 39 is also mounted and has a peripheral cam-groove 40 with a lateral deflection 4l and is engaged by a pin 42, carrying a roller 43 and connected to the rear end of a feed-arm 44, fulcrumed on the top of the bed 1, as at 45, and having a plurality of apertures 46 therein for the pur'- pose of adjustment and to `regulate the stroke of the same. rlhe outer end of the feed-arm carries a yielding feeding-linger 47, which takes into and operates in conjunction with a ratchet face or edge 48, formed in the rear edge'of a lower member 49 of a clamp 50, which also comprises an upper freely-adjustable member 51, which is movable on vertical'posts 52, rising from the rear portion of the lower member 49 and snrron nded by coiled springs 53, bearing against the under side of the said upper member 5l to thereby normally hold the latter in elevated position. Both members 49 and'l are provided with a slot 54, and the slots in the two' members are in vertical alinement and are ofthe same contour as the line defined by the eyelets in a shoe-upper. The needle 9 vertically reciprocat-es through the slots 54 of the clamp members, and when the shoe-upper is applied to the machine it is folded so that the eyelets in opposite edge portions thereof are in alinement and then placed over the lower member 49 with thesaid eyelets accurately coinciding with the slot 54 inV said members, and while in this position the shoe-upper is clamped against accidental movement by moving the upper member downwardly thereagainst and locking it against movement or tendency to return to its normal elevated position by a cam-lever 55, veccentricall y fulcru med on an upright 56, rising from the rear portions of the lower clamp member 59. The clamp 50 is removably held on the outer end of the bed l under the needle and needle-bar through the medium of a transversely-extending supporting-bar 57, centrally connected to a flat arm 58, attached to the adjacent portion of the bed, land normally bearing on the said supporting-bar is the lower member 49 of said clamp, which also has sliding movement on the bar during the feeding operation through the medium of the feedngerl47, carried by the feed-arm 44, successively engaging the teeth of the ratchet 48. The supporting-bar 57 and a portion of the arm 58 enter a retaining-guide 59 on the under side of the rear portion of the member 49 of the clamp, as shown by Figs. l and 6, the dimension and curvature of the said guide being snch as to cause the supportingbar 57 to hold the entire clamp in proper position and permitvit to be shifted in a transverse direction in the arc of a circle over the end of the bed.

IOO

The rear j upper depending flange 60 of the retaining- `loopingframe Gl, which comprises a pin-bar 62, having a plurality of pins 63, extending in a rearward direction and in a plane at right angles to the said barwhich is under the therefrom and on which the pin-bar 62 is freely d movable and held inward to bring the ends of the pins 63 normally in contact with the outer face of the guide 59 by springs 69, surrounding said pins 68 and bearing at opposite extremities against the pin-bar and the contiguous faces of the arm 67. Y

To change the stroke of the end of the arm 44, carrying the linger 47, and consequently change the extent of the feed 'of the upper holding device, the screw 45 is released and reset in other of the openings, 46, the latter registering with similaiopenings 46a in the eeaese bed, as shown in Fig. 8, the arm in the adj ustment shown being arranged for its greatest stroke.r Y Y The lace or thread from the opening 34 in the whirl-head 33 is brought upwardly and looped over the pins 63, and in commencing the operation of feeding and looping the thread or lace through the eyelets of the shoeupper the clamp 50 and all the parts carried thereby, including the loop-frame 61,-are simultaneously moved to the right in looking at the end of the machine, as shown by Fig. 3, by releasing the feed-finger 47 from the ratchet 48 and again setting the said feed-fin! ger in proper position in the saidratchet. This adjustment ofthe clamp-frame is con- 4tinued far enough to the right to bring the first pin in close relation to the needle 9 when the latter descends directly over the Whirlhead 33.

In the bearing extensions 5 and 6 a cast-oft is also movably mounted and consists of a vertical rod having a lower inwardly-bent extremity 7l, normally in Contact with the needle 9, the said cast-oft being provided at its upper end with a stop-collar 7 2, adapted to be engaged by a linger 73, slidable in a vertical direction on the same above the upper bearing extension 5 and preferably integrally formed with a clamping socket or cap 74, fitted on the upper end of the needle-bar. To the under side of the bearing extension 5 a bearing-clamp is located, and therethrough the said cast-ott has movement, the clamp serving to hold the cast-oit in true position relatively-to the needle-bar and prevent too-4 loose movement, so as to cause the said cast' off to effectually operate in the desired manner or to carry out its lintended function of casting ottl the loops of the thread or lace from the needle-hook 35. Below the clamp 75 a stop-collar 76 is adjustably mounted on the cast-off and is engaged by a projection 77, secured to the pin 19, forming the connection between the lever 10 and the needlebar 8.

In the operation of the machine the shoeupper is clamped under the needle-bar in the manner hereinbefore explained and with the line of eyelets coinciding with the slots 54 in the clamping members 49 and 51, the clamp 50 having been first moved to the right in Ylooking at the machine as shown by Fig. 3

and until the pins 63 of the loop-frame 6l are disposedin starting relation to the shoe-npper above. The operation of the drive-shaft 15 through the pulley 16 will cause the eccentric 14 to vertically reciprocate the pitman 13, and thereby oscillate the lever 10, which iirst moves the needle-bar 8 in a downward direction, and after the needle-bar has moved downwardly a predetermined distance the cast-oit 70 moves in the same direction until the lower extremity comes in contact with the eyeletdisposed inthe path of the needle 9, and lfrom this time the cast-off remains inactive and while the yneedle continues downwardly into the whirl-head 33,

whichhas been operated by the segmental gear 29 and connecting-rod 27 [and the means for actuating the latter to form a loop, which is caught by the hook 35 of the needle 9 and drawn upwardly through the eyelets of the shoe-upper in alinement until the lower extremity of the'ca-s't-otf 'is reached, when the operation hereinafter more fully explained will ensue, and the thread orlace iu loop form will be disengaged from thehook 35, and at this time the feed-arm 44 is horizontally oscillated. by the deflection 4l of the cam 40 to thereby cause the feed-finger 47 to move the clamp 50 and all parts carried thereby one step toward the left or such a distance as to bring the next unoccupiedpair of eyelets in the shoe-upper Vin the path of the needle, when the same operation ensues, and continues until all the eyelets have been threaded ,or laced or as many of the same as it is desired to connect. It will be seen that the thread or lace, which is ofva temporary character for the purpose of lasting, Vdoes not pass over the edges otthe lacing-flies, and the strain during the lasting operation is exerted in a direction transversely of the flies, and thereby permits the shoe-upper of the completed shoe which has been so treated during the lasting operation to be laced closely or so that the edges of the lacing-flies may be .drawn together and also have the upper t well over the instep and in accordance with the form of the last. Heretofore the means employed for holding the upper of alace-shoe during the lasting operation permitted the lacing-flies to pull away from each other and made it difticult to closely lace the completed shoe or have it t with comfort andA regularity over the instep. The stroke ot the castoft will be regulated by adjusting the collars 72 and 76 to accommodate different thicknesses of material forthe length of stitch, and by adjusting the pin-bar 62 through the medium of the screw 66 in t-he slot 65 the loop of the thread orlace may be lengthened or shortened, kso as to accommodate uppers having eyelets placed close to the edge of the flies, as it is apparent that the closer the eyelets are to the fly edges the shorter the loops must be. When the last stitch or loop is drawn upwardly through theterminal eyelet-of the series operated on, itis caught by the hand of the operator and a suitable length of the thread orlacing drawn upwardly and secured to one of the adjacent previously-formed loops, so that it may be conveniently reached after lasting for the purpose of lremoving this temporary thread or lacing. In the'operation of inserting the lacing through the eyelets of the upper the'needlepmakes a descent through the first pair ofv alined eyelets and into the center of the Whirl, with the hook of .the said needle just below the upper surface of said whirl', the cast-ott` during such descent ofthe needle remaining in yclose contact relation with the upper eyelet of the pair being at the time operated upon. The whirl then moves from left to right and ICO IIO

` carries the lacing or thread around the frontZ of the needle and disposes said lacing or thread in the hook of the latter, and the needle now ascends with the lace or thread therein, and when the hook thereof reaches the plane of the upper eyelet., as shown by Fig. 11, the cast-off covers the said hook and firmly holds the lace or thread in the latter to thus form aloop. The parts are so arranged that when the clamp 50 is shiftedto start the lac# ing operation the irst pin 63 will be in-such position that the iirst updrawn lace or thread loop will be brought to bear against the rear portion thereof, as shown by Fig. 12. After reaching the highest point of its movement the needle again immediately descends, the clamp having been in the meantime shifted' to bring the space between the first and second pins 63 under the needle, as shown by Fig. 13, to pass through the next eyelets,-and after reaching the latter the cast-O again remains on'the uppermost eyelet, while the needle continues to descend, as before, to the whirl and again have the lace or thread thrown around the hook thereof to form a second loop. As the needle moves upwardly from the top surface of the shoe-upper the loop of lace or thread is between the needle and castoif and under updrawing tension to form a loop, this joint upward movement of the needle and cast-off continuing for a` comparatively short distance above the plane of the upper,when the needle-hook becomes cleared from the cast-off and immediately descends through the loop, followed after an interval by the cast-off, that descends to the planeof the upper and holds the loop until the needle again ascends with a new-caught portion of the thread, which is drawn through the previously-formed loop to lock the latter, the cast-o operating as before. The next upwardv movement of the needle d traws the loop of the lace or thread upwardly between the first two pins and through the second pair of eyelets and the first-formed loop,which has been held in place by the cast-off duringthe second descending movement of the needle, through the second set of eyelets and down tothe whirl, as shown by Fig. 13, to thereby interlock the loops. The cast-off again engages the needlehook, and the needle and cast-off rise above the clamp with the second loop, as in the first instance, the clamp again being shifted as before to place a succeeding set of eyelets under the plane of movement of the needle to cause the second loop to be drawn against the seco'nd pin 63 and bring the space between the second and third pins under the needle. This operation is regularly successive until all the eyelets of the upper have been engaged in a similar manner, and it will be seen that as the loops are formed and drawn above the plane of the upper the clamp is shifted to carry the loop from one set of eyelets to the next set of the latter. After the eyelets are all engaged the pin-bar 62 is drawn outwardly eees to clear the pins 63 from the loops and the upper is removed from the clamp in a prepared condition for application to a last. Previous to the removal of the upper from the clamp 50 the pin-bar 62 is drawn outwardly by hand to disengage the pins 63 from the loops or to afford means for clearance of the loops.

The advantage of the improved machine is that it overcomes the irregularities and unsatisfactory results arising from ha11`d-lacing and provides means for having every upper uniform and regular. It frequently occurs in uppers laced by hand that the strain incident to the lasting operation will cause the lacing-flies to open, owing to slack lacing, and the next upper of the pair would be laced too close, with the result that the completed shoe embodying the lasted upper that was laced too slack when put on the foot could not be made to snugly fit by the ordinary lacing meansemplo'yed in applying a shoe to a foot and the other tightly-laced upper for lasting could be drawn snugly to fit the foot, and thus a very serious objection in a pair of shoes would naturally result.

In Figs. 9 and 10 the threaded or looped lace is shown as it appears fromopposite sides ofthe upper and illustrates the secure method of holding the upper Without liability of tearing out the eyeletsor breaking through the edges of the upper during the lasting strain.
