SOLE-SEWING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 545,484, dated September 3, 1895. Application filed January 22, 1894. Serial No. 497,697 (No model.)

To all whom. it may concern/.-

Be it known that I, Louis GoDDU, ot Winchester, county of Middlesex, State of- Massachusetts, have invented an Improvement in Sole-Sewing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings represent- I ing like parts.

ro This invention has for its object to provide a novel sole-sewing machine a'daptedeither to stitch the upper to a sole for turned work or a welt and upper to a sole for welted work.

My improved machine contains a narrow work-rest, a curved awl, a curved thread pusher or inserter, a thread-guide, and a thread-measuring hook to pull oft' from the tension device a quantity of thread for the next stitch to be made, and a suitable feedzo ing device. In another application made by me, Serial No. 497,696, filed January 22, 1894, I have shown and described a machine for making a like stitch, the awl and thread pusher or inserter being, however, illustrated z5 as straight and as attached to carriers adapted to be slid in a guide-box movable at right angles to the direction of the feed of the material, the awl being adapted to be thrust into the material and to be retracted,

3o leaving a hole for the thread, and then the said frame is tipped, as referred to, to place the forked part of the thread pusher or inserter in line with the awlhole to meet the thread held distended between a stationary thread-delivery and the hook of the measuring device.

In this my present invention I have mounted the carriers for the curved awl and thread pusher or inserter side by side, so that theyI 4o may be oscillated about a common center of motion, the awl being actuated to enter the Work, after which it is retracted and the awl and thread pusher or inserter are moved .laterally, the feeding device holding the material until the thread pusher or inserter is put in position opposite the awl-hole. In order, however, to make the stitch referred to and employa curved awl and pusher side by side,

' I have been obliged to impart to the thread- 5o guide a slight movement substantially at right angles to the direction of the length of the feed, a thread-measuring device engaging the thread at one side, co-operating with said thread-guide, stretching and laying the thread in the path of movementof the thread pusher or inserter as it approaches the awlhole.

One feature, therefore, of this present invention may be said to be a sole-sewing machine includingthe following instrumentali- 6o ties: a work-rest, an awl-sector, an attached curved awl, a thread-pusher and the sector carrying it, devices to move said sectors laterally in unison and to rock them alternately,

a thread-guide, and a thread-measuring dev6 5 vice to draw the thread therefrom and to move it into the path of the thread pusher or inserter, substantially as will be described.

Figure l vin front elevation represents al sufficient portion of a sole-sewing machine 7o containing my present improvements to enable myinvention to be understood. Fig. 2 is a right-hand end elevation thereof, the fast member of the clutch-pulley represented at the right hand in Fig. l being omitted. Fig. 3 is a sectional detail in the line Fig. l, looking to the right; Fig. 3a, a detail of the thread pull-off. Fig. 3b is a view showing the Work-rest and pitch-gage, together with the pointed feeding device, engaging the sole and 8o part of the thread-insertar. Fig. 4 is a section in the line x, Fig. l, looking tothe left. Fig.

be described, which supports numerous parts. Fig. 6 is a detail of the thread-measuring de- 85 vice and the slide to which it is attached. Fig. 7 is a detail showing the end of the th readguide and part of the work-rest, pitch-gage, and Welt-guide. Fig. 8 is a detail showing the thread-guide and its carrier detached; 9o Fig. 9, a detail of the lever for moving the work-rest. Fig. 10 shows part of a turned shoe, and Fig. 11 shows part of a Welt stitch ed to an upper/,and sole as it may be in the machine herein to be described.

The column A, adapted in practice to rest upon the Hoon-has at its upperendasuitable head A', which constitutes the rigid framework of the machine, parts lof the head serving as bearings for a main shaft A2, and-other roc parts to be hereinafter described. The main shaft has, as herein represented, at its righthand end, viewing Fig. 1, suitable fast and loose pulleys A3 A4 of the clutch variety under the control of a moving device or actuator A5, connected with a suitable treadle, (not shown,) so that the constantly-moving member A4 of the clutch may be made to engage at suitable intervals the fast member A3 of the clutch and rotate the shaft when desired. Such devices are old and common in United States Patent No. 265,227, and need not therefore be herein further described.

The main shaft a2 has fast upon it two hubs B C, the hub B having at its peripherya camgroove b and a cam-face m15, (see Fig. 2,) and near its edge a cam b', and at its inner side the hub B has a cam-groove b2. (See Fig. 3.) The hub C has in its periphery a cam-groove c and a cam-face cx, and at its inner side an awl cam-groove c', (see Fig. 4,) and at its outer lefthand side it has a second camgroove c2, the outline of which is represented by dotted lines in Fig. 4.

The framework has suitableopenings cr hearings for the receptionof a rod or shaft D, upon which is clamped, by suitable setscrews d, (see Fig. 5,) a movable hollow frame D', said set-screws entering threaded lugs of, as herein shown, a split sleeve or hub d', the said hub being clamped firmly to said rod, the ends of the rod, as herein provided for, being therefore free to slide hack and forth in the bearings in the frame.

The frame D is of peculiar shape, and, as herein represented, it has projections d, one of which is broken off in Fig. 5, said projections having suitable holes, as cl3, to receive a pin or stud d4, which constitutes the fulcrum on which is mounted the hub e of the awlsector e', (see Fig. 4,) to which is attached in suitable manner the awl e2.

The hub e of the awl-sector serves as a bearing for the hub fof the sector f', to which is secured the segmental thread pusher or inserter f2, adapted to act upon a measured thread and push it into a hole made by the awl,.as will be hereinafter described. The awl-sector derives its oscillating movement from a toothed sector-lever e3, mounted on a rod e4, confined in suitable bearings of the head A by set-screws e5, the bearings being split so as to be pinched upon the rod, as best represented in Fig. 2, the rear end of said lever e3 having a roller or other stud to enter the cam-groove c', before referred to. The sectorf derives its movement of oscillation from a toothed sector-leverjs, having also at its pivot the rod e4, said lever having a suitable roller or other stud which enters the cam-groove b2 at the inner side of the cam B.

The movable frame D' has a roller or other studcl, which enters the cam-groove b at the periphery of the hub B, said cam-groove reciprocating said frame D laterally back and forth, as will be described.

The framework has bearin g at As A9 on or forming apart of the head A', for a shaft A10, upon which is mounted to rock and slide lougitudinally thereon the feed-frame b3, having an arm b4, provided with a suitable roller or other stud b5, (see dotted lines, Fig. 4,) to enter the cam-groove c2 in cam C, to rock the frame on the shaft A10, said frame having adjustably attached to it by screw b the feeder 117, having one or more penetrating points b1?. The roll h5 is kept pressed into the groove c2 by a spring 198, (see Fig. 1,) placed within a hollow part of the shaft A10, the outer end of said spring being acted upon by a screw b9', screwed into a threaded hub of the bearing A9.

vThe feeding-frame is provided with aroller or other stud 113, (shown in full and dotted lines, Fig. 4,) which enters the camgroove c at the periphery of the hub C, said camgroove reciprocating the feeding-frame laterally.

The shaft A10, between the hubs of the feeding-frame, is shown asprovided with a slideblock blo, clamped on said shaft by a set-screw blz in ears of the splity hub of said block, flanges or feet of said block resting and sliding on tracks Z713 of the movable frame D', said block preventing any rocking movement of the said shaft. The block blo serves as a carrier for the thread-measuring device Z914, the shape of which is best shown in Fig. G, it having near one end a hook 2, a set-screw 3 holding the threadmeasuring device in place. The block h1 has a roller or other stud Z215, (see Figs. 3 and 6,) which is kept normally against the cam b' bythe spring ha, before referred to, and said block and thread-measuring device have given to them a to-and-fro motion with relation to the thread-guide g.

The thread-guide g, shown as a hollow rod with a notched orbifurcated endg', is at tached to a carrier g2, having a thread-passage 2O therethrough, and shown as having a split hub g3 attached by screw g4 (seeFig. 3) to a rocking stud g5, mounted in theframe D', the carrier being located in such manner with relation to the said frame as to be adjacent thereto throughout the length of the threadpassage 20, for a purpose to be described, the rear end of the carrier having a roller or other stud g, which is acted upon by the peripheral cam CX of the cam-hub C, (see Figs. l and 4,) a spring 10 (see Fig. 3) keeping the roll g against said cam, the latter causing the front end of the threadguide to be raised and lowered, so as to put the thread issuing from said guide and held by the thread-measuring device in the path of movement of the thread pusher or inserter as it approaches the awlhole, the thread measuring device having drawn olf enough thread for the next stitch and holding the said thread so that the said thread-pusher will meet it at a point distant from the last stitch equal to the distance of one awl-hole from another plus one-half the length of the loop of thread to be left in the awl-hole.

The thread t is taken from a suitable waxbox t', in which the wax is heated by steam IOC IIO

from a pipe t2, steam entering the frame D at p (see Fig. 4) from asuitable source of supply, which may be a steam-chamber.

The pull-off consists of a lever h h2, pivotedat m5, and having (see Figs. 3a and 4) a finger h3, on which is a roller h4. (See Fig. 5.) The lever h has a roller or other stud h5, which also enters the cam-groove b2. The thread is led from the stripper o, under the studs or thread-guides 4 5, as in Fig. 2, and over the roller h4 of the pull-0E, so that when the said roller is raised, as in Fig. 2, the pulloff draws thread from the stripper and waxbox. The thread-tension devices-a suitable wheel or device about which the thread is given a turn on its way into the thread-guideis prevented from rotating during theaction of the pull-off by the detent t4 in engagement with teeth t5, connected to a part of the tension device, the latter being carried by the frame D. )Vhen the pull-olf is moved, the pawl t4 prevents retrograde movement of the tension device s and causes to be pulled from the wax-box enough thread for a new stitch, so that there is always left slack thread brehind the tension device, so that the 4threadmeasuring device (it having engaged the thread) will, in drawingV the thread from the thread-guidahave only to overcome the friction of the tension device, which is usuallyT slight. The work-rest 'm consists of a narrow thin edge connected to an arm m', attached adjustably by a set-screw m2 to a carrier-bar m3, placed in guideways in the head A, so that it can slide only longitudinally. The work-rest has, as shown, a pitch-gage m4, combined with it, which bears on the bottom of the sole while the upper or welt is pushed against the work-rest, that depending on whether a turned or a welted shoe is being stitched. I desire to hold the work-rest forward firmly while the stitch is being made and to relax such pressure while the feed is acting to feed the shoe. To provide for this, I have mounted on the frame D, at m5, a lever m6, provided with a roller-stud m7, which is normally kept against the peripheral cam m15 of the cam-hub B by a spring m8 (see Fig. 9) in a little tube at the lowerend of said lever, an adjusting-screw m9 being applied thereto to control the force of the spring, the inner end of said spring entering a pocket (shown by dotted lines, Fig. 3) connected to the frame D'.

The lever m6 has at its lower end teeth m10, which engage teeth m12 of the shank of the work-rest. (See Fig. 3.)

The arm ma of the work-rest, when a welt is to be attached, has secured to it by screws n a welt-guide n', which is of such shape andv depth as to let one edge of the welt come between the work-rest and upper when the latter contacts with a shoulder formed at the edge of the sole, as in the sectional detail', Fig. 1l.

Fig. lO shows part of a sole and upper adapted for a turn-shoe.

Having described the construction of the parts, Iwill now describe the operation of the same. First assuming that the frame D is in its position farthest to the right, viewing Fig. 1; that the work-rest is way forward; that the feed device has been moved to the left, has acted to feed the material, and that it is yet down with its points in the material and acting to aid the operator in keeping the upper and' sole clamped closely together against the narrow work-rest; that the thread-guide g stands with its notched delivery end in its uppermost position, and that the awl and thread pusher or inserter are both out of the material, now the thread-measuring device will be made to engage the thread of the lifted thread-guide, preparatory to pulling therefrom and the tension device beyond it enough thread for the next stitch.

About as the measuring device engages the thread the thread-guide will be lowered to remove the thread to be drawn out by the measuring device from the path of the awl and the measuring device will be started to pull off the thread, and as soon as the measuring device is out of the way of the awl the latter will be started forward to enter the work yet held between the work-rest and the feeding device, and the measuring device will continue its movement to draw off thread and will complete its backward movement as or about as the awl retires from the work. The awl having been retracted, the frame D will be moved to the left sufficiently far to put the end of the thread pusher or inserter f2 opposite the awlhole, the feed yet remaining stationary, and at the same time the thread-guide and measuring device will move with the frame, but the work-rest will not move. During this lateral movement of the frame D to the left the thread-guide g will be lifted sufficiently to put the thread held between it and the thread measuring device across the hole made by the awl and in the line of movement of thethread pusher or inserter, so that as the latter is moved forward itwill engage the thread and put it into the awl-hole.

While the pusher is acting to put the thread into the awl-hole the th read-measuring device will be moved toward the thread-guide, suclr movement being effected independently of the frameD by the spring bs, the threadguide then giving up to the pusher the thread held by its hook; but as soon as the thread pusher or inserter is lifted from the material the frame D is again started toward the right.

IOO

device is again started toward the left to again feed the material the work-rest will be pulled back slightly, so that while the feeding device is acting to feed the material the pressure between the material and the workrest will be somewhat released; andthe feed having been effected, the work-rest will be again pushed forward, this happening, however, before the awl enters the work. The hollow frame D (see Fig. 4) receives steam, as stated, at the inlet p, the steam following along a channel 6 therein, (see dotted lines, Fig. 4,) at one side of said frame, thence upwardly along a channel 7 below the top of the track 513, and back to the rear end ofthe frame at its opposite side through a suitable channel 8, (see dotted lines, Fig. 3,) and out at the outlet p2 into pipe t2, and thence in to the usual hollow casing surrounding the wax-box t', as best shown in Fig. 2, whereby said frame is heated, the thread-carrier g2 being supported, as described, so that the heated portions of the frame are contiguous or adjacent thereto and heat it throughout the extent of the thread-passage 20.

l-Ieretofore while the opera-torwas removing a finished shoe and replacing it by a shoe to be stitched a considerable portion of the thread was cooled by exposure to the air, and the operator had to draw off and sever such cold portion before he could begin the stitching of the next shoe, the thread being drawn off until the heated portion was brought up to the stitch-forming devices.

By maintaining the thread heated throughout its length from the wax-box to and particularly immediately adjacent to the stitchforming devices, I obviate the waste occasioned by cutting off a portion of thread for each shoe, and I increase the rapidity of operation of the machine, for the thread is always heated and ready for use at the stitchforming devices.
