WILLIAM o. mnynnoi BEVERLY, massacnnsn'r'rs, assisnpnmo UNITED snot: V mncnmmw comrany, or rarnnsoN, NEW Jnnsnma conron'a''rIoN' on NEW JERSEY.

To all whom it may concerns Be it known that I, VILLIAM, G. Maren, a citizen of the United. States, residing at Beverly, in the county of Essexand state of Massachusetts, have invented certain new and useful Improvements in shoe-Sewing Machines; and I do hereby declare the fol lowing-to he a full, clear, and exact description of the invention, such as will enable others Skilled in the'art to which it appertains to make and nsethe same.

This invention relates to shoe sewing ma; chines, and more particularly to sole sewin' machines provide'ch with a straight hoo needle'and devices cooperating therewith to. form a chainstitclr in which the ork is supported by a rotatable work support or liorn which extendswithin the shoe, such machines heing'generiflly known in the art as machines of the McKay type. i V

In general, the object of the invention is to produce a simple and compact machine of the McKay type, which will run smoothly at high speed, which .will producebetter work than the machines which hmeheretotore been produced,.and in which the work may be introduced and removed with the minimum loss of time.

In shoe sewing machines of the McKay type the work is engaged upon one side {by the upper surface'of the tip of the horn, and upon the other by a presser foot, which parts are relatively movable to accommodate work of varying thicknesses; The thread is,laid in the hook ofthe needle bya looping de rice or whirl located in the tip of the-horn, and the needle during its retractingonloopdrawing stroke acts to tighten the preceding stitch and to draw oif thread from the supply for the formation of the next stitch. In order that the needle may he threaded properly. and in order that the stitches may he formed and tightened in a uniform manmiin each cycle of operations of the machine. the needle must occupy substantially the same position with relation to the horn at the end of its Work piercingstroke, and must retract substantially the same distance from the work during each loop drawing stroke, regardless of the thickness of the work. In machines of the McKay type at present in common,connnercial use. the horn is vertically fixed, and the presser foot is movable with relation to. the horn to coinprnsate for varying thicknesses of work. In

these machines the limit of the work iercing stroke of the needle is fixed, while t feloop- I accordance with changes in the vertical position of the presser foot, due to variations in ithe thicknessofthe work. Machines have been devised in which the resser foot i s'vertically fixed and the horn isarrauged for vertical movement, and in these machincsthe.

needle retracts to thesa ne position in each cycle of operations, but its work piercing stroke is varied to compensate for variations in the position of the horn," du to changes in the thickness of the work. In cominei cial machines of the'McKay type, the needle" actuating mechanism hasa provision for lost motion between limiting stops, the position of one of which is controlled by the presser foot so as to; produce the necessary variations in the needle, stroke, and frictional devices are employed to hold the needle stationary during the periods of lost motion. This mechanism has marked disadvantages, cer tairrof which make it impracticable to run the machines at high speed. The abruptengagement of the moving parts with the stops causes objectionable vibration, noise and wear on the parts, especially when the ma.-

chine is run at comparatively high speed. i v

The frictional devicesemployed to hold the needle stationary during the periods of lost motion are objectionable on account of the wear on the needle bar produced thereby wl'iich tends to throw the needle out of afiiien ient'lwi'tli the whirl, and on account ofthe v,h fitiii'g of the needle bar, which often re- "sults when th machine is run at High speed, and, also beca ise of'the loss of powerincident to the employment of such devices. In these machines the needle bar at the end of the loop-drawing stroke of the needleis controlled only by the engagement of e frictionaldevices therewith, and the needle is liable to overthrow and cause imperfect work, particularly when the machine is running at high speed. It has been a serious problem in the manufacture of machines of the McKay type to devise a needle actuating mechanism of comparatively simple construction which would produce the necessary variations in the needle stroke in a reliable manner which would be mechanically efli,-

cicnt, and which would operate at high speed mechanisms have he n f proposed, but such mechanisms have b for the most part complicated in const ction, expensive to manufacture, and i iiicient in the transmission of the pow e for have been peculiarly subject to wgar and consequent derangement.

One of the objects of the present invention is to provide mach nes of the McKay type with a needle actuating mechanism which is comparatively simple in construction and eliicient in operation, which will produce the requi'ed variations in the stroke of the needle in a reliable manner, and which will operate smoothly even when the machine is run at high speed.

In accordance with this object, the invention contem lates a revision of an improved nee le actuating mechanism com prising various novel and advantageousfeatures clearly set forth in the following description and particularly pointed out in the claims.

The features of the invention will be readily understood from an inspection of the accompanying drawings taken in connection the axis of the main shaft 0 with the following detailed description.

In the drawings illustrating a machine embodying the invention in its preferred form, Figure 1 is a view in side elevation of the complete machine; Fig. 2 is a view in horizontal section, takenthrough the base of the machine; Fig. 3 is a view in front eleva tion, part] in section, of the head of the machine; ig. 4 is a view in side elevation looking from the right, illustrating all except the rear portion of the head of the machine; Fig. 5 is a plan view, partly in sec tion, of the portion of the mac iine shown in Fig. 4; Fig. 6 is a sectional view taken substantially on the line 6-6 of Fig. 4, looking in the direction of the arrows; Fig. 7 is a sectional view taken substantially on the line 77 of Fig. 4, looking in the direction of the arrows; Fig. 8 is a view in vertical sec tion taken substantially in a fplane through the machine, illustrating the forward portion of the head of the machine; Fig. 9 is a detail view, partly in section, illustrating particularly the variable clamp connection forming part of the presser foot liftin mechanism; Fig. 10 is a detail sectional view taken substantially on the line 1010 of Fig. 8; Fig. 11

is a sectional view taken substantially on the line 11-11 of Fig. 10; Fig. 12 is a. sectional view taken substantially on the line l212 of Fig. 4; Fig. 13 is a view in side elevation,

partly in section, of the mechanism illustrated in Fig. 12, looking from the left; Fig. 14 is a sectional View taken substantially on the line 14-44 of Fig. 13; Fig. 15 is a sectional view taken substantially on the line'1515 of Fig. 14; Fig. 16 is a detail view, partly in section, illustrating particularl y the mechanism by which the feed point is connected with its actuating mechanism; Fig. 17 is a detail sectional view illustrating the vibratory lever and cooperating locking bolt and certain devices for controlling the engagement of the locking bolt with'the lever, all of which constitute parts ofthe stop mechanism; Fig. 18 is a view similar to Fig. 1?, illustrating certain of the parts in dill'erent positions.

The machine illustrated in the drawings comprises the usual vertically reciprocating straight hook needle indicated at l, whichduring each cycle of oprrations is projected through the work into position to receive the thread from a. looping device located in the tip of the horn. The cast-off for preventing the previously formed loop from catching in the hook of the needle as the needle is retracted is indicated at 2. The work is supported during the sewing operation by the horn 3, which in the resent embodiment of the invention is vertically fixed, but is arranged to rotate in the usual manner. The work is engaged between the upper surface of the tip of the horn and presser foot -l which is arranged for vertical movement to accohnnodate work of varying thicknesses. The work is fed at intervals during the operation of the machine by the feed point 5, which is projectedinto the work nd is then advanced in the direction of the seam to feed the work. i

The presser foot 4 is secured to the lower end of a bar 5" which is mounted to slid" 1 i vertically in suitable guides on the fr uie. The lower portion of the presser foot bar slides in a guide in the forwardly projecting portion 4" of the frame of the machine, and the upper portion of the bar 5 is reduced to 105 form a. cylindrical extension or rod 6 which is arranged to slide in a sleeve 7 secured in an upwardly or forwardly extending bracket Son the frame. The presser foot is held down on the work by a heavy coiled spring 9 which surrounds the upper cylindrical portion of the presser foot bar, and engages at its lower extremity a shoulder on said bar. and at its upper extremity the lower end of the sleeve 7. The downward 116 movement of the presser foot under the action of the spring 9, when no work is in the machine. is limited by a nut 10 threaded upon the upper end of the prcsser foot bar. By adjusting the nut l0 on the presser bar, 120 the vertical position of the presser foot when no work is in the machine, and the tension of the spring 5), may be varied. The sleeve 7 is threaded into the bracket 8, and may be adjusted vertically to vary the vertical posi- 126 tion of the presscr foot when no work is in the naicliine without varying the tension of the spring l The sleeve 7 is held in adjusted position by :1 lvck nut 12. By suitable adjustments of the nut 10 and the sleeve 7, the lower limiting position of the prcssci foot may be changed. and the tension of the spring 9 may be adjusted as required lay the ciaracter of the work which is heiug oper ated upon.

As is usual in machines of this type. the Presser foot is lifted during each cycle of operations to free the work from cnjiagcment with the upper surface oi the horn and permit the work to be fed. it is evident that the vertical position of the prcsser foot when in engagement with the work varies with the thickness of the work. and in order that the Presser foot may be lifted from the work substantially the same distance in each cycle of operations, regardless of its vertical position when in engagement with the work. a variable friction clamp connection is provided in the resser foot lifting mechanism,

the relative positions of the parts of which.

are determined when the pl'esscr loot is down in engagement with the Wm'li. and

which is locked during the liftin c action of said mechanism. In the construction illustrated, the mechanism for lifting the prcsser foot comprises an arm 13 secured to a rock shaft 1% and provided at its extremity with a pivoted block 15 which engages in a suitable recess in the presser foot bar. The rock shaft 1 t extends rearwardly suhstantially parallel with the main shaft of the machine. and a second arm 16 is attached to the rear extremity of said rock shaft. The arm 16 is rovided with a recess or pocket ll (sec Fig. 9) at its extremity for the reception of a series of friction leaves 18. A series of friction plates 19 are arranged to slide through openings in the outer cud of the arm 16, and are interfitted between the frie tion leaves 18. The ends of the friction plates 19 are pivotally connected with a lever 20 which is loosely mounted on the shaft 14, and carries a cam roll 21. which engages a cam groove 22 in the cam disk mounted on the main shaft 24 of the machine. In order to clamp the friction plates 19 to the arm 16 so that they cannot move through said arm when the lever 30 is actuated. a lever 24 is pivoted upon a transverse stud 25 carried by the arm 11;, and is provided with a recess adjacent the end of the shorter arm in which engages a projection on the clamping plate 26 which fits in the pocket 17 and engages the face of one of tin plates il The lever 24 is actuated to Force the clamp ing plate 26 inwardl) in the pocket and clamp the friction plates 19 to the arm 16 by means of a coiled spring 2T {st-o Fig. a seated at one end in a recess or bore in the end of the shaft 14. and at the other in a recess in the end of the long arm of the lever 24*.

During each cycle of ope ations. and while the presser footislilteddhe lever 24 is actn ated to relieve the pressure upon the outer friction plate 19. thcrelrv unlocking the rlanip and permitting ihc prcswr foot to he iorrli d down on the u'orh h the (oiled spring The unlocking, ol the clamp pcr niits the friction plates lEl to auloniaticullv adjusttiu-nisclvcs in the outrrcnd ot the arm loin arrordanrcnithrhunnos in the \ci'firul position of the prcssor l'ool due to variati ns in the thickness. ol Ilu- \iorh. li lorc the prusscr fool isliitrddluilllllli! isagain lorlird to ronncct lhc 'ilill arluutrd ll'\l.i' ill rigidly niih the arm iii to rnulilc said l ver to lift the prrsser foot. in the pr sent invention. lhc lcrrr 2 l is artnatcd llll lll\ll lo lllilmk tinclump. in the ron irnrlion illnslratvd. the rod ol' the longrr arm of the ion-r 2i is rwrsscd to rcrciic one rxtrcinitv ol' :1 slrn in, the other end of whirl; strut. is ri-roiiwl in a similar recess in the and of a screw Bi tln'rudcd into an arm 2W of :1 lei-or piiotvd on a stud Ill.

To this end a pair of links 58 are pivot-ally connected at their forward can treinitica with the link 54, and at their other extremities are both connected w'uh a head 5!) formed en an arm fill of a lever oi. pivoted loosely on. the shaft 14. The lever 61 is provided with a laterally extending arm .32. the lower face of which engages the upper face of an arm 63 fast on the rock shaft ll. The faces of the arms 62 and 6B are normally held in engagement by a coiled spring 64 surrounding a bolt 65 passing tl'll'ullgll both arms. said spring engaging at its reepcctive extremities the arm 62 and a not on said bolt. Through the connection of the arm 13 fast on the shaft ll: with the prcsser foot liar. the angular position of said shaft is determined by the poaition of the prrsser loot. \Vhcn the presses: font rises or falls. the shaft 14 is rotated and the arm 153 swung ahont the axis of the shaft.

During the sewing operation. the machine is driven by means of a helt 122 passing ahout a pulley 123 fast on the main shaft? it of the machine. and connecting: said pul ley witl a pulley 124 mounted upon a driving shaft l2? located in the l ase ot' the ma ehine. The shaft 123 is provided with a loose pulley 126 and with a pulley 127 splined thereto hut movable longitudinally thereof. \\l]l('lt is driven by a helt from the power shaft. The pulley 1'21 is loosely mounted on the shaft 12.") in front of the pulley 121 and is provided with a ring 128 of t'rirtiou material for engagement with the adjaeent surfaee of the pulley 127. A fourth pulley 129 is pinned to the shaft 125, and the pulley 124 carries a second ring 130 of friction material for engagement with the adjacent surface of the pulley 125?. The shaft 125 is arranged for longitudinal movement in its hearings, and when said shaft is thrust endwise toward the rear of the niachine, the pulley 1'11 is clutched between the opposed faces of pulley 129 and pulley 1:2? and therehy caused to rotate with said pulleys. hen the shaft is released and allowed to move, forwardly or toward the front of the nuiehine. the loose pulley 12-1 as carried out of clutching engagement with the pulleys 121' and 1:29. The shaft 125 is actuated to clutch the pulley 121 l'ietp'een pulleys 1:27 and 12% hy suitahle connections from the treadle -13. Said connections (one prise. a. hell crank lever pivoted on a stud 131 and provided with an arm 13 which engages the. end of the shaft 125. T ie other arm 132* of the hell crank lever is provided with a forked forward extremity which eulhraces a rod lilil. which is the rod which con trols the device for throwing the stop lllflll' anisin into operation. The rod 131* is core nected at its lower end with a lever 131, which lover is arranged to he actuated from the treadle. A collar 13? is secured to the rod 133 ahove the arm 132. and the rod 133 is yieldingly held in raised position hy the coiled spring 1am. The treadle 1 is pivoted on a horizontal stud 123T carried by a hlock mounted. on a vertical swivel pin 138. This manner of mounting the treadle permits the treadlc to he swun e vertically and horizontally. The rearwardly extending: arm 13%) of the treadle is provided with a lateral projection 140 which is adapted to engage heneath the forward end of the lever 1734. When the projection 140 is beneath the arm of the lever 134, and the treadle is depressed, the rod 133 is moved downwardly and actuates the bell crank 132 to thrust the shaft 125 r rwardly and thereby clutch the alloy 124 x the shaft and start the machine into operation. \Vhen the forward end of the treadle is released, it is lifted by a coiled spring 141, allowing the rod 133 to be lifted by the spring 136 to release the lever 132- 132. The shaft may then move forward to release the pulley 124 from clutching engagement with pulleys 127 and 129. The rearwardly extending arm of the trcadlc is provided with a second projection 142"for engagement beneath a forwardly extending arm of the lever -12 by which the prcssor foot is lifted. The lateral moremcnt of the. arm 13$) of the trcadle is limited by the engagcment of the end of the arm with stops 143 and 144. These stops are so placed that when the treatlle is swung horizontally to hring the end of the arm 139 into engagement with the stop 143, the projection 140 will he brought heneath the lever 113 1, and the projection 142 will he away from beneath the lever -12, and when the treadl is swung in the opposite direction to bring the end of the arm 139 into engagement with the stop 111 the projection 1&2 will be hronght heneath the lever -12 and the projection 140 will be away from beneath the. lever 134. To prevent the actuation of the treadle when the treadle is in an intermediate horirontal )osition in which the projections Ho and 1 -12 might both he in position to engage respectively levers 134 and 42, a forwardly projecting lac 141 is formed on the bracket which supports the. lovers 131 and 42 hetween the stops 143 and 1-14..

in order to permit the work to he removed when the seam has been completed, and another piece of work to he introduced easily and quickly, the machine is provided with mechanism for autormitically arresting the rotation of the shaft at the point in the cycle of operations when the needle is retraeted out of engagement with the work and the presser foot is free to be lifted. hen the treadle is released at the end of the sewing operation. the mechanism which hrings the maehine to rest with the parts in proper positions for the removal of the shoe is thrown into operation. This mechauisui comprises a friction clutch, one memher of which is driven at slow speed in a forward direction. and which, when the clutch lnenihers are engaged, first acts as a hralie to slow the shaft down to the slow speed of the forwardly driven member. and then to drive the shaft at slow speed in a forward direction to hring the devices which finally a rrest the rotation of the shaft into engagement. The friction clutch consists of clutch inemlrers 145 and 146, of which the memher 117i is loosely mounted on the main shaft 21 of the machine. and is driven at slow speed in the same direction as the normal direction of rotation of the shaft 24, by means of a spiral pinion 148. mounted on a hollow shaft or sleeve 149 journaled in hearings 150 in the machine frame, which meshes with the. teeth of a spiral gear 147 secured to or formed integral with the clutch nicmher 1-45. The hollow shaft 149 is constantly driven during the rotation of the main shaft of the machine through a friction clutch contracting said shaft with a pulley 151 which is continnousiy driven by means of a belt 151 connecting said pulley with the pulley 129 mounted on the shaft at the base of the machine. The clutch connection hetween the shaft 149 and the pulley 151 consists of a clutch. member 152 secured to or formed integral with the shaft 149. and a second clutch member 153 carried by the pulley 151. The pulley 151 is journaled upon a rod or shaft 151 eitcnding through the hollow shaft 149, and is confined between collars carried by the rod, as clearly shown in Fig. 14.
