T0 all whom t may concern."

Be .it known that I, PERCY WV. SHAW, a citizenv of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new anduseful Improvements in Thread-Fastening Machines; and I do hereby declare the following'to be 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 use the same.

The present invention relates to thread handling machines and more particularly to f machines of this type Which'are employed pass two loops of thread successively through v for temporarily fastening the upper endsole of al lasted shoe together preliminary to the permanent sewing of the inseam.

One Object of the present invention is to provide a machine of this type which employs a hooked needle for forming and inserting a thread fastener in the work. With this object in view one feature of the invention contemplates the provision of a hooked needle, means for actuating the needle to the work, means for passing one loop of threadl through; the other, and means for drawing upon the thread from the supply end'to lock the loops in the work and set the stitch. The provision of a hooked needle for forming the thread fastening enables a thread to be employed which completely fills the hole in the work and forms a stitch which is locked tightly upon its completion. The utilizing of a hooked needle for forming a stitch also has other mechanical advantages invr 'connection with the operation of the machine which will be. obvious to those skilled in the art.

A further object of the invention is to provide a machine for the formation and insertion of a thread fastener which occupiesv a minimum space lengthwise of the shoe land the insertion of which may be readily and accurately determined by the operator to of theA invention consists in the combination" with a back gage and channel guide for positioning ythe shoe, of thread fastener forminsole lip of a lasted shoe. ln the simplesty 'l and 1119s?

ing and inserting` devices for inserting ay stitch transversely through the upper and' which has yet been devised, this'is accomplished by providing work positioning devices andstitch forming mechanism to which a relativefvertical movement is 11nparted during the 'formation of a stitch to insert thev stitch transversely of the insole lip of a shoe which is held in a substantially tion; Fig.`2 is a side elevation ofthe machine shown in Figi; Fig. 3 is a top plan view of the machine shown in Fig. l; Fig. t isa detail upon an enlarged scale illustrating the construction of the thread cutting mechanism; Figs. 5 to 7, inclusive, are details illustrating the construction of the thread looping and clamping mechanism; Figs. 8 to'll, inclusive, are details illustrating diagrammatically the formation of the thread 4fastener in the upper and insole lip of a shoe; Figs. 12 to 20, inclusive, are de-y tai'ls illustrating diagrammatically the 0peration'of elevating the toe thread from the path of the needle when forming the second stitch for anchoring the toe threadin place; Fig. 2l is a view showing the lasted shoe after the first stitch has been formed for anchoring the toe thread and prior to passing vthread about the toe; Fig. 22 is a view illustratingA the shoe after thev thread has been passed about the toe and prior to the formation ofthe second fastening; and Fig. 23 lis a view illustrating the method of fastening the toe by inserting two anchor fastenings at opposite ends ofthe toe wire to retain the toe wire in position.

The present machine is intended lto insert a. plurality 'of separate unconnected thread fasteners about the sides of a lasted shoe in order to temporarily retain the shoe in its lasted condition and allow the removal ofy the metallic fastenings prior to the Vpermanentl sewing of the inseam. In the vpresent invention this is'accomplished'by inserting a plurality of vertical stitches transversely p Patented Aug. 21, 1917. Application ala May 2s, 1914. serial Nb.' 841,624.

through the upper and insole lip of the` lasted shoe between the metallic fasteners, and severing the thread at the completion of the stitch. The thread severing mechanism is under the control of the operator and when passing about the toe may be rendered inoperative in order to bind in the toe by means of-a toe thread, as shown clearly in thev drawings. It will be obvious to those'y skilled in the art that when lasting a shoe the metallic fasteners are vinserted at the points of greatest strain upon the upperand .inl order yto hold the lasted upper mostefithe direction of the length of the shoe. The

present type of'fastener is also employed advantageously in anchoring the ends of the toe wire in place when it is desired to retain the toe of the shoe in this manner. As

n will be `observed from an inspection of Fig.

23 of the drawings the fasteners may be insertedacross the ends of the toe wire and after the anchor tacks are removedthe wire is bent in a reverse direction to lock it in place. i

In the illust-rated embodiment of the inventionthe thread fastener consists of two loops of thread passed successively` through the lasted upper and'lip of the insole by a hooked needle. The use of a hooked needle for the formation of the thread fastener permits a thread to be employed which com pletely fills the hole in the work, forming a tightly locked` fastener which -holds the lasted upper securely in place.

A curved hook needle 1 is clamped in a needle segment 3 fulcrumed at 5 and operated from a bell crank indicated at 6, onel arm of which is connected to the needle segment through a link 7. rlhe bell crank is fulcrumed upon the machine frame at 8 and is operatively connected with `a path cam formed in a cam face 10 and designedto impart two loop formingmovements and a thread releasing movement to the needle during each rotation of the cam shaft.

Prior to the engagement of the thread by the needle, the hook 82 is moved along the thread toward the shoe in order to grasp the thread in close .proximity to the short end, after which the thread clamp is allowed to clamp the thread in the hook. When the needle has been advanced through the work, .the lobper is actuated. to lary that POM/i9!! Q the thread between the looper. and the thread supply in the barb of the needle, after which the needley is retracted drawing thread from the thread supply to form the first loop. Upon the second passage of the needle through the work, the looper, which is upon the opposite side of the needle, is returned to its initial'position to again lay the thread in the barb of the needle for the formation of the second loop. After the second loop has been drawn through the work, the needle is advanced sufficiently toy throw the loop out of the` barb of the needle, the thread clamp is opened to release the thread and the -looper is then moved back 4to again engage with and clamp the thread between the work and thread supply prior to the severing of the thread. To this end thevlooper, asa whole, is supported by a cylindrical stud 16 extending through a bearing 17 formed in the machine frame and actuated through an arm 19 extending upwardly from the stud shaft 16 and operatively connected with a path cam formed in the face 20'., The end of the shaft 16 is connected with ythe lower` end of a lever 2Q fulcrumed upon the machine frame at 211- and having its opposite endactuated by a barrel cam 26. The connection between the lever 2'?. and the shaft 16, asv

will be noted from an inspection of F ig. 2, transmits lengthwise movements to the shaft while permitting the shaft to oscillate independently of the lever. With this construction, movements of the looper toward and from the shoe are imparted by rocking the looper and shaft 16 in the bearing 17l and the transverse movements of the looper to .lay the thread in the barb of the needle are imparted by a bodily movement of the shaft llengthwise in the bearing. In order to. clamp the thread duringthe formation of a stitch, the looper consists of a'sleeve 30 and a hook 32 s lidingly supported therein. rlhe hook is actuated to clamp the thread against the lower end of the sleeve by a spring 34 which is interposed between the shoulder formed upon the sleeve and a slide block 36 mounted in a head 37 formed upon the end of the shaft 16. In order to open the clamp against the action of the spring the slide block is providedwith a cam roll 3S which engages with the surface of a peripheral cam 40 having a periphery of sufficient width `to allow for the necessary transverse movements of the looper. With this construction, the thread is vyielding-ly clamped by the spring 34 and is positively released at the completion` of thestitch by the cam 10 which, as will be seen from the drawings, engages with the cam roll only during the time that the thread clamp is open, thus allowing the looper to rock freely during the .formation of a stitch without affecting the operation `of the thread clamp.

When the needle is retracted to draw the` second loop'of thread through the work, it

is essential that some means be provided fory inclosing the barbof the needlev and for casting off the first loop to allow :the second loop to be drawn therethrough. Tofthis'end a combined 4'needle guide rand cast-0E is Yprovided which servesnot `only to support the needle during the piercing of the work but insures that the firstloopof thread shall bel cast off the needle tocause it 'to encircle the* second loopafter it has vbeen drawn through the work. A needle guide 45 is fulcrumed at 5 .and is provided with a toothsegment-LG meshing with a corresponding segment 47 formed upon one arm of a bell crank 49, fulv` crumed upon the machine frame at Oand actuated through a peripheral caml. rlhe bell crank is permanently main-tainedin op? erative relationl with the vcam. by a vtension spring connecting` the arm.V of the bell crank with the' frame vof the machine. During the yfirst advancing movement Iof the needle, the needle guide is-fady vanced into close-proximity with ,the work .to support the needle after which it is retracted to allowthe loop ofr thread to be drawn rthrough the work. Upon advancing the needle a second time, the needle guide is again moved forward'into close proximity with the work and remains in this position until thev barb of the needle carryingthe; second loop engages with theneedle guide serves to pass it through this loop, thus en` ablino'it to readily cast olf the loop when the needle is retracted. l

After the thread clamp has released ther short 'end of the thread and priorrto lits re` engagementv with the thread,-;the atake-up acts between the thread supply" and Ithe Work to tighten the first-loop and draw the second loop encircled thereby into the work.

The thread passes; from the thread supply over. any suitable'form of tension device in-` dicatedv at 55 a-nd'lneXt under guide rollers 57 and 58. A 'take-up roll 60 engages with the thread between ,theguide rollers andl is journaled upon the lower end of;an arm 62v 'secured to a rockshaftl. A secondarm 65'is also secured to the rock shaftand is op` eratively connectedv at its free end with a path cam formed in ythe face 67 which serves to actuate Vthe take-up inthe usual' manner to tighten the stitch. The lasted shoe is retained in position duringthe for mation ofthe thread fastening by aback gage and channel guide arranged to engage with opposite sides of thev insole lip and vlasted upper. After-the shoe has been -posi tioned. properly and upon starting the machine the back gage is actuated to clamp the between substance and hold the shoe during the formation of the thready fastening. After the shoe .is clamped yin position it is held by the two members during the entire operation 'of inserting a thread fastening, both the back gage and channel guide being depressed to feed the shoe for the formation of thevsecond loop of thread. At the completion Iof the thread fastening operation the back-gage is automatically retractedto release the shoe.. The shoe is positioned in proper relation to the stitch forming mechanism by a channel guide 70 which is adjustably secured to a head 72 and is arranged to project into the channel formed at the base of the insole lip. ln order to provide for the feeding of the shoe the head 72 is fulcrumed. upon the machine frame at 74 and is operatively connected to a cam path formed in the face 75 through a cam roll 76. With this construction the head 7 2 is rocked to depress the channel guide and lasted shoe during the formation of the stitch. In order to clamp the shoe against the channel guide a back gage 78 is slidingly mounted in the head and is operatively connected at its rear end with a lever 80 fulorumed upon the head at 8l and having its upper endr operativelyl connected with a second path cam formed in the face 75 of the cam disk 40 through a cam roll 82. It is` desirable that the back gage shall be first moved into engagement with the inseam to` position it properly and shall thereafter bev forced against the inseam with a yielding pressure to clamp the 1 between-substance firmly during the formation of the stitch. This .method l,of operating the back gage exerts a certain lasting veffect upon the upper and the tendency of the parts to spread out to their initial Vpositions when the back gage is yretracted insures the formation of a tight stitch in the work. To this end'the lower end ofthe lever 80 is pivotally connected to al rod .83 which slides in a bearing forming apart of the back gage slide 78. The

yielding'connection between the rvrod and back'gage slide is secured by the provision cfa coiled spring 87 interposed between the bearing and locknuts 88 threadedl upon the end of the rod 83. .Movement of 'the rod with relation to the bearing 85 by means of the spring 87 is limited by a stop collar 90' gage takes place and further movements of iis` the lever SOserve to compress the spring 87l and yieldingly press the back gage against the shoe. The back gage is locked in its ade vanced position by apawl 92 which is allowed to move into engagement at certain predetermined intervals with a ratchet tooth plate 93 secured to the back gage slide. The pawl 92 is mounted upon one end of a lever 94 fulcrume'd upon the rocking vhead atv 9 6 and having a cam roll 97 jour-naled upon its rear end which is adapted to engageat the proper intervals with a periph eral cam 99. This cam serves to positively unlock the back gagey and allow it to beretracted at the proper time, and the spring 101 connecting the arm 94 and locking headv serves to normally move the pawl into engagement with the ratchety plate The back gage 7S is' removably secured to the` back gage slide as indicated at 105 and is provided with a vertical slot 104 to allow the passage of the needle therethrough when forming both loops of thread.

Upon the completion of the thread fastening the thread is severed close to the surface of the work by a knife 106 slidingly mounted in the back gage, as shown clearly in Figs. 2 and 4. This knife consists of a thin blade with a cutting edge arranged to' coperate with and shear the thread. against the edge of the backgage slot, and pivotally connected at its upper end through a clamp 108 to one arm of a bell crank 110 fulcrumed upon the rocking head at 112. The bell crank normally maintains ythe knife in a retracted position by means of a spring 113. This retracted yposition is determined by the engagement ofa stop 114 formed uponfthe second arm of the bell crank and arranged tocontact with the side of the back gage. In order-to rock the bell crank and impart a cutting stroke' to the knife a stud 115 projects from the lower end of the arm 116 and is engagedby the slotted `end of a lever 118 pivotally supported at 120 upon a. de-V pending arm 122.` The arm 122 is pivoted to the machine frame at 123 and is provided with a cam roll 124 which engages with and is actuated by a face cam 125. construction the knife is normally maintained in an inoperative position bythe spring 113, but at the completion of the thread fastening the cam 125 rocks the -bell crank 116 to impart a positive cutting stroke to the knife. It is desirable to provide mechanism under the control of the operator for rendering the cutting mechanism inoperative in order that when desired, two thread fastenings may be connected by a length of thread. To this end, as observed clearly in Figs. 1l and .4, the'lever 118y is provided with a slotted end which normal-ly engages with a stud 115, but may be removed from engagement with the stud to break the Operative COQPGQQD by .foklg the .lever Vith this `about the fulcrum` 120. -To this end the Opf posite end of the lever is connected toa treadle rod128 which through the provision of ya suitable spring is normally raised to maintain the operative connection between the actuating cam and cutting knife intact. Upon depressing the treadle, however, this connection is brokenv and the lever 118 oscillated without imparting a corresponding movement to the bell crank.v

It will be noted that in forming the first loop of thread for the fastening the needle engages with the thread betweenthe thread clamp and supply and that wheny forming the second loop the'nee'dle engages with the thread Vbetween the thread clamp and the first loop, there-being sufficient slack thread between the thread clamp 'and material tov permit the formation of this second loop. Infforming the thread fastening after the toe threadhas been laid in place there is no short end and as the thread clamp is man nipulated to lay the bight of threadl over the barb of the needle this toe thread must be held out of the way ,in order that it shall not be 'engaged bythe needle and drawn into thev work. To this end an` auxiliary' finger or hook is arranged to engage with the toe thread and remove it from the path ofthe needle during the vformation of the thread fastening. 'In the illustrated embodiinent ofthe invention this auxiliary finger is normally maintained in an inoperative position but is connected with mechanism under the control of'pthe operator through which it may be' actuated at the proper time., A hook 130 is pivotally mounted`at132 upon the end of a lever 133 and is operatively connected with a cam slot 135 through the camvr'oll 137 in order to oscillate the hook and move it transversely at predetermined intervals. The lever 133 is moved vertically by a stationary cam roll .139 which engages with a curved cam slotA formed in the lever. The rear end of the lever 133 issupported by one arm 142 of a bell crank fulcrumed at 143 uponlthe lower end of an arm 145. The arm 145 is connected with a'path cam-formed in the face 146 of the cam disk 147 through a second arm 1495- as shown clearly vin Fig. 3- of the drawings. The bell crank is connected to the arm 149 througha pair vof arms 150' and151 secured respectively to the arms 145' and 149, land a tension spring 152 connecting the ends of the two arms and normally maintaining a tail 153 formed upon the hub' of `the bell crank in engagement witha lug 154 formed uponthe arm 145. With this` construction when Athe arm 149 is rocked by the cam'the arms 142 and 145 are moved therewith as a single integral arm to impart a vback and forth movement to the lever 133. The leveris retained in an inoperative position by a locking lfnelnfber 155 'Pivo-ted losl follows: Afterthe shoe is positioned propat 156 and having one end connected with the treadle rod 157and its opposite end engaging with a shoulder- 159 formed upon the rear end of the lever 133. The treadle rod normally retains the locking member in an operative position by any suitable type of spring, not shown, andwhenthe lever is lockedin a retracted lposition the move- Aments ofy the arm 149l simply rock the arms 145 and 151 and expand the spring'152 without ymoving the lower end of the arm 142 which is pivotally connected to the lever.

The machine is'provided with any suitable form'of singlerevolution clutch which serves'to start the'machine upona depression of the starting treadler and allows the y machine to operate during one complete operation of the'cam shaft, after which it is automatically stopped. This mechanism is actuated through a treadle rod 160 connected to the free end of lan operating arm "162.whichf actuates a clutch link 163 having a hook'shaped lower end which engages with a gin '165 ,projectingfrom the arm 162. v I he operation of the present machine is as erly for thev insertion of a .thread fastening 4thellmachine lis started and the bacl-l gage e is actuated to clamp the upper and insole lipjagainstthe channel guide.

'shoe isclamped in 'position thelooper 32 is After the moved along the thread into close proximity yto the' end and-the clamping sleeve is then actuatedto tightly lock the thread in the looper. The hooked'- needle is advanced through'the work and the looper is moved transversely to lay the thread-in' the barb of the needle, as shown in Fig. 8. The needle is then retracted to draw thev loop of thread through the worlrand the back gage and channel Aguide are depressed, after which the needle is-again advanced, bringing the severalparts of the machine into the position Lshown in Fig. 9. *With the needle inthe position shown in Fig. 9 the looper is returned to its initial position, laying that portion lofthe thread between the first loop .and

the looper in the barbl ofthe needle-,as shown -`in-Fig.`1-O. The needle is-inally retracted to draw the second loop through the worky and during this movement ofthe needle the needle guide is actuated to protect the barb and cause `the first loop to slide over the second, as shownin Fig. 10; `The needle'and the thread clamp then release the thread and thetalie-'up is actuated to draw upon the supply end of the threadl and pull the encircling loopv intovthe work to lock the stitch, as shown in Fig. 11, after which 'the thread lis cut in close' proximity to the upper by the thread cuttingv knife 106. When passing about the toe, as shown clearly in Figs. 21

and 22, the thread ycu'tting mechanisml is lrendered inoperative,vv andl 'at the lcompletion of the stitch thread is drawn from the sup- :the path of'the needle and t-o this endian auxiliary thread engaging hook is moved into position beneath thethread and is then elevated to hold-the thread from the path of the needle during the formation of the stitch, as shown clearly in Figs. 12 toV 19, inclusive. 1n some instances it is` desirable to retain'the toe wire and lock it at its vopposite ends by thread fastenings, in place of the usual anchor tacks. To this end the presends ofthe toe wire bentin a reverse direction to lock it in position. After the requisite number'oflthrea'd fastenings have been inserted in-a lasted shoe al-l of the metallic fastenings may be removed prior tothe'pernianent sewingy of the inseam.

lent thread lfastenings are conveniently utilized, aswshown'clearly in Fig. 23, and the l/Vhile it is-preferred to employ the spel Vcific construction and arrangement of parts lshownxand described, it .will be lunderstood that this. construction .and arrangement is not essentialexcept so far as specifiedfin the claims, and ymay bel changed orlmodiied -without departing from the broader features ofthe invention. f y i The invention having been described, what is claimed ist f f l' y 1.
