SEWING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 593,577, dated November 16, 1897.

Application filed August 25, 1894. Serial No. 521,306. (No model.)

To all whmn it away concern.-

Be it known that I, HERBERT E. HAWES, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification. 7

While many of the features of this invention are applicable separately and in combition to a diversity of purposes, the special purpose of my invention is to perfect and improve the machine for making buttonholewaistbands for boys trousers illustrated in my other application for patent, filed May 4:,

1893, Serial No. 472,977, wherein a strip of mittingly through a buttonhole stitching mechanism, so that the buttonholes are automatically formed in the strip at proper intervals, and said strip can then be divided into the proper lengths to form the buttonholewaistbands. To this end I have devised mainly novel mechanism for operating the drawing mechanism in harmony with the buttonhole-stitching mechanism, for varying the intervals between the buttonholes, for slacking the strip between the drawing mechanism and the buttonhole-stitching mechanism during and to accommodate the reciprocation of the strip with the work-clamp, for cutting or parting the thread from the work on the completion of each buttonhole or piece of stitching, for fastening and retaining the end of said thread in the needle until the commencement or it may be partial or total completion of the next buttonhole or piece of stitchin g and for then releasing the thread, for cutting or dividing the buttonholed strip in lengths or sections suitable for waistbands, for applying to each of said strip-sections a trade-mark, stamp, or symbol, and for automatically discharging said marked and buttonholed sections or waistbands from the machine into a receptacle therefor.

In order that my invention may be clearly ascertained, I shall first give a detailed description of the mode in which I carry the invention into practice, and then point out its various features in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which I have designated the same parts by like letters of reference in all the figures.

Figs. 15 and 16 are side and plan views, respectively, showing the workclamp, thread-parter, and their operating mechanisms. Figs. 17, 18, 19, 20, and 21 are detail views, hereinafter referred to, showing the operation of the thread-separator. Fig. 22 is a cross-sectional View illustrating the operation of the strip-dividing, marking, and discharging mechanisms. Fig. 23 is a detail sectional side elevation on the line 23 23, Fig. 4, showing the strip-dividing mechanism.

For a buttonhole stitching and cutting mechanism I at the present time employ an ordinary Wheeler 85 Wilson buttonhole-machine of the kind described in my prior application, Serial No. 472,977, aforesaid, of which Figs. 1, 15, and 16 show the driving mechanism A, the reciprocating work clamp or holder B, the needle 0, and the starting mechanism and stop-motion mechanism D. On an extension of the frame E, on which the buttonhole-stitchin g mechanism is mounted, beyond and in line with the position of rest of the work-holder B, I fix the strip-drawing meche with the folding attachment.

anism, for which I prefer to employ, as in my aforesaid prior application, Serial N o. 47 2,977 aloose upper drawing-wheel F, pressed yieldin gly, as shown in Fig. 2, upon a flanged lower drawing-wheel F by which it is driven.

The strip G of indefinite length from which the waistbands are to be formed I may previously fold and hem, as by the means described in my prior applicatiomSerial No. 521,307, filed August 25, 1894, or otherwise suitably prepare for the purpose, and I may lead it to the work-holder B by means of a tension device, as described in my prior application, Serial No. 472,977, filed May 4, 1893,

or, by means of a suitable guide, directly from a bobbin or roll on which the strip is previously wound, as illustrated in my said prior application, Serial No. 521,307, in connection I arrange the drawing-wheels F F to pull the strip G between the presser-foot B and the lower clamp-plate B of the work-holder B transversely to the length of the buttonholes, so that the buttonholes will extend transversely of the strip, as shown.

To operate, the drawing mechanism F in harmony with the buttonhole-stitching mechanism, I connect the driving mechanism A of the latter by means of a worm-shaft A and worm-wheel A with a cam-shaft H, mounted transversely on the frame E of the machine, and on said shaft H, I fix a cam I, (shown in detail; in Figs. 8, 9, 10,11, and 12,):to operate the drawing mechanism F and pull the strip. G a predetermined distance through the workholder B once during each rotation of the said cam-shaft H. For thus operating the. drawing mechanism from the cam I, I engagewith said cam an antifriction cam-follower I, fixed on a lever I which is pivoted on the frame E, and is provided, as shown in Fig. 6, with a slotin which is held ad j ustably one end of a link 1 theother end of which is pivoted to a clutch I, Which is itself pivoted to swing on the. shaft H. I prefer to form the clutch I of an arm 1 pivoted toswing on the cam-shaft and carrying twopivotal toggle-leversI I whichareboth pivoted to the arm I and the lever I to the linkl The toggle-levers support clutch-shoes 1 I", which are held byor slope of the cam I'swin-gs thelever 1 the lin-k l will instantly, through the toggle-levers I 17, bind the clutch-shoes I I on the-rim I and rotate, the drawing-wheel F through an arc d'eterminedby the stroke of the cam-1ever I As the cam. I thencauses the link I to returnby gravity or it. may be by a spring the link will instantly loosentheclutch-shoes 1 Pen the rim, the springs 1 yielding, and return the clutch I to its normal, position, where i t.rema ins until the next operation of thedrawin g mechanism. To secure thed-raw-r cam portion J. tion of the disk J 3 in harmony with the; drawin g-wheel F against movementduring the return of the clutch I I prefer to mounta similar but reversely-arranged friction-clutch K at the opposite side of the rim I and on an arm K,depending from the frame E,as shown. The operation of the drawing mechanism would in this way be regulated to draw the strip Gforward an equal distance on the completion of each buttonhole thereon, so that the buttonholes will be formed at equal distances apart; but it is often necessary to vary the distances between the buttonholes, and I have therefore provided mechanism for adj usting the cam I, and thus the stroke of the operating-clutch I and of the drawing-wheel F at certain predetermined stages in the formation of the series of buttonholes. In the example here given I have shown such camadjusting mechanism in Figs. 8, 9, 10, 11, and. 12, arranged for the formation of five buttonholes at equal distances, then a longer space,

i then three buttonholes at shorter andequal.

distances apart, then a. longer space, and so on, each set of three buttonholes being; intended for the rear of the completed waists band, the set of five for the front, and the intervening wider spaces for the sides of the waistband.

The cam-adj ustin g mechanism which I here i employ, as shown in Figs. 8 to 12, comprises a pivotal expanding active portion J of the cam I, held in contracted position by a spring J, but adapted to be spread to increase the stroke of the cam I at certain times by cam 5 projections J held adj ustably at the desired,

points in the periphery of a split disk J and engaging as said disk is. turned a corre sponding cam projection J on the expanding I cause the automatic rota,-

in g mechanism F, and thusthe automatic vai riation of the drawing, as desired, by fixingthe disk J on a short shaft J mounted ec- ,centrically and to turn in the body of the. cam I, and fixing on said shaft J- a toothed wheel J which I arrange toen gage, as shown in Fig. 12, a fixed pawl J and to be turned thereby the distance of one tooth at each ro-- tationof the cam I. The adjustment of the cams J 2 peripherally and radially on the disk: J 3 will thus accurately determine the periods; and extent of the variation of the drawing springs I' 'in engagement with opposite sides of arim- 1 ,formedon thelowerdrawing-wheel F With thisconstruction, as the active partv and the distances between the buttonholes on the strip.

To insure the starting of the buttonholestitching mechanism on the completion of each drawing of the-strip, I employ a cam K 011 the cam-shaft H, arranged'to at the propertime and through the cam-follower-K, connecting-rod K and connections K operate.

the starting mechanism D, substantially as described in my prior application, Serial. No. 472,977, the cutter being actuated to. cutzthe buttonhole and the stop-motion automatic-- ally stopping the stitching on the completion:

be depressed automatically to clamp the strip G on the completion of each drawing and before or on the starting of the buttonholestitching mechanism and to be raised to free the strip on the completion of each buttonhole and before the commencement of the next drawing by means of a cam- L, (shown in Fig. 5,) mounted on the cam-shaft H and engaging a cam-follower L, which operates at the proper time to raise and lower the spring-depressed resser-foot B, through the rod L and angle-lever L (shown in Fig. 1,) and the link L lever-plate L and stud L thereon, (shown in Figs. 15 and 16,) the stud L engaging the upper work-clamp-plate arm 13 as the lever-plate L is swung on said arm B to'which it is pivoted. I provide this means of operating the presser-foot B as a convenient means also of operating my new thread-parter and thread-fastener, which I have invented for the particular purpose of automatically separating the threads from the work on the completion of each buttonhole and for automatically fastening and retaining the separated end of the thread in the needle until the commencement, or it may be whole or partial completion, of the next buttonhole.

The form of thread-parting device which I have illustrated in the drawings, particularly Figs. 15 to 21, consists of a piece M, pivoted in the corner of the upper work-clamp plate B to swing horizontally across the corner of the slot therein, and thus between the raised needle and the end of the completed buttonhole. I preferably sharpen the lower outer edge M of the piece hi and arrange it to swing between the outer part B of the upper clamp-plate B and a blade M fixed on and below the part B of the clamp-plate B so that when the blade M is swung on its pivot M as shown in Figs. 18, 19, 20, and 21, its upper edge M, which is preferably rounded, as shown, will carry and grip the thread between it and the part 13 and immediately afterward, or it may be at the same time, the blade M of the movable piece M will cooperate with the fixed blade M to shear, cut,

or part the threads from the work, while the parted end thereof will remain fastened, as described, and thus retained in the needle. As a convenient means of operating this form of thread parting and fastening device automatically on the completion of the stitching of each buttonhole, I mount the vertical pivot M to which the movable piece M is fixed, in a bearing 1 erected on the upper clampplate B and provide said pivot with an arm M", which I connect by means of an operating-rod M with the leverplate L before described, for raising the presser-foot. I so adjust this presser-foot and thread parter and fastener operating mechanisms that on or after the completion of each buttonhole and before the ensuing drawing, as before described, the incline L of the cam L, Fig. 5, first operates the lever-plate L and thus the piece M, so as to part and grip the thread without acting on the presser-foot until the stud L on the lever-plate L strikes the operating-arm B of the upper clamp plate, when the presserfoot is also raised and the work freed to permit the drawing. On the completion of the ensuing drawing and before the commencement of the next buttonhole, the presser-foot and thread parter and fas tener being, meanwhile retained in position by the cam-lever U, the presser-foot is first permitted by the cam-decline L to be depressed upon the work by its spring E the stud being. meanwhile retained against the upper clamp-plate arm B and the end of the thread thus still fastened, then the stitching of the next buttonhole commences, and when it has progressed far enough for the piece M to clear the needle and threadthe cam-decline L permits or causes the piece M to be returned by its spring M to its primary cutting position and the gripped end of the thread, now retained by the stitching, to be released.

I have also devised a slacking mechanism for easing or slacking the strip G between the drawing mechanism and the buttonholestitching mechanism during the reciprocation of the work-holder, and thus prevent the same from drawing on the strip, substan tially as illustrated in Figs. 2 and 3, wherein it will be seen I conduct the strip from the work-holder to and between the two rollerguides N and N, the guide N being stationary on the frame of the machine and the guide N, mounted in bearings N pivoted on the mountings of the guide N and having an operatingearm connected by a' rod N with an arm N on the drawing cam-lever-F, so that on the return of said lever after each drawing and during the initial operation of the buttonhole-stitching mechanism the movable guide N will be swung upward out of line with-thatis, over the fixed guide and slackthe strip G, and on the completion ofthe buttonhole and stoppage of the work-holder the strip will by the same means be again taken up before or with the commencement of the drawing.

I also provide mechanism for dividing the buttonholed strip G into sections of the required length, each to make a buttonholewaistband, substantially as follows. -As best shown in Figs. 2,3, 4, 22, and 23, I mount on the frame of the machine in the line of feed and beyond the drawing mechanism a transverse vertical blade 0, beneath the lower cutting edge of which the strip G is thus fed by the drawing-wheels F F. I fix the blade 0 on a blade-holder O, which I make adjustable on the frame E, longitudinally to and from the drawing mechanism, so that the division of the strip G can be accomplished at the required points of the buttonholed strip. On the adjustable blade-holder 0', I likewise provide anarrow table 0 below and immediately in advance of the blade '0, to conduct the strip Gr thereto, and immediately below [actuated catch Q pivoted on the bladeand beyond the blade; 0., I arrange atable O- to conduct the strip G therefrom. I further prefer to constitute of the edge 0 of the eduction-table O a lower cutting-blade to cooperate with the upper blade 0 and out or divide, the strip passing therebetween, and for this purpose I arrange the said lower blade 0 to swing upward across the said upper blade 0 by providing the eduction-tableO' with bearings on one side thereof mounted on a longitudinal pivot 0 held in the upper adjustable blade-holder O and in the frame of the'machine. To accomplish the operation of this form of strip-divider at the required time on the completion of a certain number. of forward drawings, I fix an antifriction camfollower P onthe cam-shaft driving wormwheel A to engage and actuate a cam P, fixed on a slide-bar 1?, having a slot P to ride on the cam-shaft H, and reciprocated in opposition to the cam-follower Pby a spring 1?. In the slide bar P is. formed a slot to which I fasten adj ustably by means of a screw P one end of a lever P which is pivoted on v a. shaft P mounted in bearings on the adj ustable blade-holder, the adjustable connec tion of the lever P and slide-bar P to permit the adjustment of the strip-divider before referred to.

The pivotal lever P carries-a pawl P which engages. and turns the distance of one tooth a ratchet-wheel P fixed on the shaft P, which ratchet-wheel in this instance I provide with eight teeth, so that the shaft P is rotated oncefor-each eight reciprocations of the slidebar 10. and revol nations of the controlling camshaft II. On the cam-shaft P I fix also a secondary cam P to engage a cam-follower p on the movable eduction-table O and thus operate the strip-divider once for each eight operations of the. buttonhole stitching and drawing mechanisms, so that in this instance the strip G will be divided on the completion of each set of eightcomposed of separate sets of five. and three bnttonholes.

I also provide mechanism for stamping or otherwise applying a name, symbol, or other mark to each section of the strip so divided substantially as follows: As best illustrated in Figs 3., 4, and 22, I fix on the rising side of the eduction-table O a standard Q, on which I pivot to swing toward and from the strip G, passing over said table 0 a stamp Q, bearing the mark or device to be applied to. the waistbands, and connect the shank Q of said stampv to. the table 0 by a spring Q to normally hold the stamp elevated above the strip. On the standard Q, I alsopivot an inking-pad G2,, which is pressed normally against to ink the face of the stamp Q by a spring Q but is arranged to be swung downward out of the way by said stamp when the latter is swung on its, pivot down upon the strip G. I likewise form the shank Q of the stamp. Q with a shoulder Q which is automatically and normally engaged by a springholder 0, when the eduction-table O is lowered, as shown in Fig. 4, in such a. manner that when the eduction-table O is swung upward, as before-described, to divide the strip the shank of the stamp Q on the table 0 Will be detained by the fixed catch Q until the stamp is swung downward thereby past the inking-pad Q and upon the strip G, as indicated' in Fig. 22, marking the same, when the catch Q slips oh. the shoulder Q on the stamp-shank and allows said stamp to be again thrown upward over the inking-pad by its spring Q tions or waistbands thus marked substam tially as follows and as best shown in Figs. 4 and 22, wherein it will be seen that I fix an additional cam R on the secondary cam-shaft. P to engage a cam-follower R on and near the pivoted side of the eduction-table 0 so as. to follow up the action of the dividerand It will be understood that I do not intend to limit my invention to any of the special forms or combinations of mechanisms herein shown and described, as I may in practice employ vastly different forms. of mechanisms to the same end and may omit any of the various component mechanisms without materiatly affecting the operation of the others in, so far as my invention is: concerned.
