Definitions
- This invention relates to machines for operating on shoes and is illustrated herein as embodied in a machine for adhesively attaching strip welting to the bottoms of shoes of the type which have on the bottom margin of the upper an outturned flange for use in attaching the sole.
- the flange is trimmed and a beveled precoated welting strip is adhesively attached to the abbreviated outturned flange by guiding the beleved edge of the welting strip into the crease between the flange and the upper and simultaneously pounding the beveled edge into engagement with the flange by a reciprocating hammer means, or pressing and squeezing it into engagement with the flange by co-operating pressure rolls.
- this flange is delicate and the treatment received by the beating or rolling action of machines heretofore employed is too harsh and tends to distort the flange, stretching it so that after the welting strip is attached it does not lie close to the upper and, accordingly, does not give a pleasing appearance in the finished shoe.
- one feature of the machine comprises means for supporting strip welting having a precoated beveled edge in a position to facilitate attaching the welting to the outturned bottom flange of a shoe.
- the aforesaid supporting means is constructed and arranged to advance successive portions of the welting with its precoated beveled edge exposed for engagement with the flange of the shoe to the position of attachment to enable the operator continuously to attach the welting to the flange of the shoe by turning the shoe and simultaneously pressing its flange in engagement with the beveled edge of the advancing welting.
- the supporting means includes spaced members adapted to engage the unattached welting with its beveled edge projecting therefrom and as it is advanced toward the position of attachment, by means provided for this purpose, successive portions of one of the members are caused to move toward the other to squeeze the welting to flatten it and to apply supporting pressure thereto so that when the flange of the shoe it brought into engagement with the beveled edge, the latter will not readily deflect.
- Cam means is provided for moving the successive portions of the one member toward the other. as the welting is presented to the position of attachment, the cam being constructed thereafter to release the portions and thereby to release the welting from supporting pressure so that it may slip from between the members. During the movementof the successivev portions of the one member toward the other, they are subjected to repeated'bl'ows which tend to still further flatten the welting.
- the one member comprises a plurality of independently movablesections between which there are slots or spaces, the sections being mounted to move with the opposite member as a unit.
- the opposite member is also provided with slots corresponding to the slots between the sections, and another feature of the machine resides in a cutting blade mounted for movement through the slots to sever the attached welting laid about the bottom flange of the shoe from the unattached welting adjacent to that section which grips the welting strip at the time it is to be severed.
- the holding means comprises a disk having a recess in one side near its edge the wall of which has radial slots therein, and a plurality of spaced sectors arranged opposite the wall of the recess, thereby to form spaced surfaces.
- a plunger is provided which is advanced by movement of. the knife toward its severing position to enter the spaces between a pair of teeth on a gear fixed to a shaft which rotates the holding means.
- the gear has teeth in such number that the spaces between the teeth correspond to the slots between the sectors. Rotation of the gear one way or the other by entrance of the plunger between a pair of teeth produces a corresponding rotation of the holding means, thereby bringing one of the slots into line with the path of movement of the knife.

- Fig. 4 i a View in front elevation of the machine, showing the welting strip presenting and supporting means;
- Fig. 5 is a section on the line VV of Fig. 1;
- Fig. 6 is a section on the line VIVI of Fig. 1;
- Fig. 7 is an enlarged perspective view of one of the sectors for pressing the welting strip against the face of the disk and the cam for advancing the same;
- Fig. 8 is a section through an Ayrlyte shoe illustrating at the left side the construction of the flange and the disposition of the welting strip in relation to the welt crease and at the right hand side the sole attached to the welting after the flange has been trimmed.
- the apparatus'for attaching the welting strip to the untrimmed flange has a hollow frame Ill (Fig. 1) closed at its upper extremity. Near the top of the frame bearings l Zand M are 'formed in thefront and back walls and are'arranged'to're- 'ceive for free rotation a horizontal drive shaft IS the ends of which extend beyond the walls of the frame. "On the front end 'of the shaft Hi there is mounted means l8 for holding the welting at a-predetermined position to facilitatepressing the flange of the shoe into engagement with the beveled'edge of the welting. This means is constructed and arranged frictionally to engage the unattached welting in advance of the predetermined position and to move it to-the predetermined position.
- this means consists, in part, of a disk fastened to the extreme outer end of the shaft.
- the inner side of the disk is cut away to form a circumferential recess 22 (Fig. 3) and the outer side is beveled at 24 around its outer edge face, for a purpose 'which will appear'hereinafter.
- Mounted on the shaft l6 behind the'disk 26 is a hub'26 having a plurality of openings ffirunning parallel to the axis of the shaft which slidably receive stems 30.
- 'sector shaped heads'32 are formed at the ends of the stems 39 adjacent to the rear'side of the disk 20, the heads extending radially outward from the shaft toward the circumferential edge of the disk.
- the faces 34 of the heads 32 are close to the rear sideof thedisk ZO'andbeyond the recessed portion 22 form a circumferential wall 36, which,
- welting strip 10 is led from a reel r into the groove 38 the walls of which frictionally engage the opposite sides of the welting strip, holding it with its beveled edge projecting radially from the disk 20, as seen in Fig. 1.
- the welting strip is progressively advanced to the position shown in Fig. 1 where the operator may place the shoe in a position to bring that portion of the flange 1 of the shoe 8 adjacent to the welt crease into engagement with the beveled edge of the welting strip.
- a pulley 4B freely mounted on the outer end of the shaft l5 and connected by belting 22 to a constantly driven pulley 44 journaled on a countershaft 46 at the base of the frame l9 provides means for rotating the shaft 25.
- a clutch disk 48 spiined on the shaft l6 and slidable into engagement with the side face of the pulley provides means drivably to connect the pulley '49 to the shaft f6.
- Movement of the clutch disk 48 is effected by a bell-crank lever 58 one arm 52 of which is forked to engage an annular groove 54 (Fig. 3) formed in the hub 55 of the clutch disk and the other arm 58 of which .is connected by a rod 68 to a'treadle 62' pivotally mounted near the bottom of the frame ill at M.
- a spring 66 attached at one end to the treadle 62' and at its opposite end to the frame It] holds the treadle up so that normally the clutch 48 is out of engagement with the pulley 40. Rotation of the shaft I 6, and consequently of the Welt strip holding means, is produced by holding the treadle 62 down.
- the beveled edge of the welting strip and-that portion of the flange adjacent to the stitch line with which the beveled edge of he welting strip is to be brought into engagement and adhesively united to form a permanent bond are coated with latex prior to bringing them together.
- the only pressure employed to cause permanent adhesion be tween the parts is that exerted by th operator in holding the flange of the shoe upwardly against the beveled edge of the welting strip.
- the welting strip must be held rigidly at the exact moment and point at Which the welting strip and flange are brought into intimate contact and yet prior to this time the welting strip must be free enough to permit relative movement in the groove 33 as the holding means rotates, and immediately following the attachment of the welting strip to the flange it must be entirely free from the groove so that it will remain stuck to the flange and will not be pulled away from it by the advancing movement of the shoe.
- This is effected herein by an annular cam 68 (Fig.
- the operating portion ofthe cam 68 extends over an arcuate portion thereof adjacent to its edge, sloping gradually from a low point at I to a high point at I2 and then dropping off suddenly at I4.
- the grip on the welting strip is gradually applied as the welting approaches its point of attachment and then is abruptly released so that there is no danger of pulling the welting strip away from the flange.
- the stems 38 pass beyond the high point of the cam 58 at E2 they are temporarily free to come and go in the hub 25. As they continue their movement and begin again to approach the low point of the cam at 'IIJ, they are brought under control so that when the ends of the stems reach the point III, they will smoothly engage the cam.
- notches I6 are provided near the rear ends of the stems 3D.
- the notches are picked up as they approach the top of the cam by an inturned rim I8 of an arc-shaped flange SI) fixed to the edge of the cam 53 and extending from a point near the top of the cam (Fig. 6) around the same to a point adjacent to the low point I8 of the cam.
- the inturned rim I8 slopes toward the low point 15.
- the welting strip runs into the groove 38 close to the low point III of the cam.
- the rim I3 holds the heads 32 prior to the engagement of their stems with the low point It at a sufficient distance from the wall of the recess 22 to permit ready entrance of the welting strip into the groove 38. Frictional engagement of the opposite sides of the welting strip is commenced as soon as the ends of the stems engage the low point of the cam.
- the welting strip usually has some irregulari ties in thickness. Moreover, as it is led around corners, for example. the tip and heel end of the shoe, it tends to become wavy. The pressure exerted on the welting by the heads 32 as they are progressively advanced toward the wall of the recess tends to eliminate any irregularities in its thickness and to flatten it out as it passes around curved portions of the shoe. It is desirable, however, to subject the welting strip also to a mild beating action as it is applied to the flange further to flatten the welting. This is suitably accomplished by striking the rear ends of the stems 39 of the sector-shaped heads 32 as they advance the welting strip and during the attachment of the welting strip to the flang.
- blows are imparted to the welting strip alone and not to the flange so that there is no danger of damaging the flange.
- the blows are delivered to the ends of the stems, through the annular cam 8 which is pivoted for thispurpose at 82 (Fig. l to swing outwardly away from the frame It, by a striker pin 84 one end of which bears against the rear side of the cam.
- the striker pin 34 is slidably mounted. in a bore 85 formed in the front wall of the frame ID and may be continuously and rapidly vibrated, except during the cutting-off operation, by a cam-operated driver 38.
- a head 98 is formed on the rear end of the striker pin 86 which abuts the end of the driver 88.
- the head I!!! is held in contact with a stop pin 9 3, which limits its outward movement, by a spring 52 disposed between the head and the inside wall of the frame If].
- the driver 68 is provided with a strap 96 which surrounds an eccentric 33 fixed to a shaft I90 journaled in the side walls of the frame.
- the shaft I00 carries a pulley III2 (Fig. 3) which is connected by a belt Ill l to the driven pulley 44 also fastened to the shaft 46 at the base of the frame.
- a link IE6 is connected thereto and to a plunger IIEB which passes through an opening III) in a transverse wall H2 extending across the frame.
- a spring IIB which pulls the link lilii, and conse quently the driver 88, downwardly out of contact with the head 99, a stop pin Hi3 being provided to limit the downward movement of the plunger.
- a bell crank I pivoted at I22 to the frame has one arm I24 connected to the plunger W8.
- a knee pad I25 is mounted at the end of the other arm I26 of the bell crank whereby when pressure is applied to the knee pad the driver 88 may be raised into contact with the head 9%.
- the pounding means may be moved into and out of operative position at the will of the operator.
- the welting strip After the welting strip has been attached to the entire bottom flange and simultaneously straightened, it is desirable to sever the attached welting strip from the succeeding unattached welting strip.
- the welting strip In order to cut the welting strip without pulling it out of the groove 38 and also to cut it at such a point that the cut end will be in readiness for application to the next shoe, that is, so that there will be no forwardly projecting, unsupported end, the welting strip is severed by passing a knife through it between the sectorshaped head which grips the welting strip at the working point and the preceding head which has just released the welting strip.
- radial slots I28 Fig.
- a knife I30 (Fig. 2) may be passed.
- the knife I3ll is mounted for sliding movement parallel to the shaft I6 in a guideway I32 formed in the front wall of the frame, an outboard bearing I34 being provided to support and guide the forward end of the knife.
- the knife is advanced at the will of the operator by downward movement of a cam plate I36 (Fig. 1) having a forwardly sloping cam slot I38 which engages a pin I40 carried by the knife.
- a link I42 is fastened thereto and to an arm I44 pivoted at I46 to the frame ID, the forward end of the arm being movable in a clockwise direction about the pivot I 46 by a rod I48 connected to a treadle 62 corresponding to the treadle 62 and pivoted to the base of the machine at 64, a spring 66 being provided for holding the treadle in an inoperative position.
- another spring I50 is provided which is connected to the arm I and to the frame ID, the latter spring assisting in holding the arm in a raised position.
- a gear I52 is fixed to the shaft I 6.
- the gear has teeth I54 (Fig. 6) thereon which correspond in number and are spaced similarly to the openings between the sectors 32.
- a plunger I55 low the gear I52 and movable into meshing engagement therewith is a plunger I55.
- the plunger I58 is slidably mounted in a central bore I58 formed in a rod I80 which passes through the wall H2 and is pivotally connected at its lower end to the rear end of the arm M4 at I62.
- a spring I64 is disposed behind the plunger I56 at the bottom of the bore I58 and yieldably supports the plunger for sliding movement therein. Since the rod I6! is attached to the arm I44, when the latter is rotated in a clockwise direction to advance the knife the plunger I56 will be moved forwardly to engage a space between one set of teeth I54 and thus operates to turn the shaft I and to center one of the openings between the sectors 32 with the advancing knife.
- the operator draws the leading end of a welting strip w from the reel r and pushes it edgewise between the walls of the groove 38 formed by the rear face of the recess 22 in the disk and the front faces 34 of the sector-shaped heads 32 at the point where the welting strip is substantially tangent to the bottom of the groove 38 (Fig. 4).
- the machine is then started by depressing the treadle 62' so that the holding means i 3 rotates, advancing the welting strip to the position shown in Fig. l.
- the operator then lifts a shoe to bring that portion of the bottom flange adjacent to the stitch line into engagement with the beveled edge of the welting strip.
- the operator advances the shoe by rotating it, thus progressively attaching the welting strip to the flange.
- the welting is flattened by the continuous beating action of the striker pin 84 which, through the cam 68 and stems 33 of the sector-shaped heads 32, impart blows to the rear side of the welting strip.
- the welting strip has been led around the entire bottom flange of the shoe, or around such portion of it as is desired, the operator releases the treadle 52, thereby stopping the rotation of the holding means I3, and releases the knee pad I25, thereby withdrawing the striker pin 85 from operation.
- the knife I38 is then advanced to sever the welting strip b depressing the treadle 62 which simultaneously alines one of the slots in the holding means IS with the advancing knife. This completes the operation and upon release of the treadle 62 the machine is ready for the next operation.

This invention relates to machines for operating on shoes and is illustrated herein as embodied in a machine for adhesively attaching strip welting to the bottoms of shoes of the type which have on the bottom margin of the upper an outturned flange for use in attaching the sole.
In this type of shoe, commonly known as the Ayrlyte shoe, as shown in United States Letters Patent No. 2,301,186, filed November 16, 1939, in the name of F. L. Ayers, the upper and lining are lasted over and secured to a midsole by a line of stitching in such a manner that the marginal edge around the bottom portion of the shoe, which is constituted by the superimposed layers of upper, lining, and midsole, projects outwardly at an angle, thereby forming a bottom flange which runs around the entire shoe. In one method of manufacture, the flange is trimmed and a beveled precoated welting strip is adhesively attached to the abbreviated outturned flange by guiding the beleved edge of the welting strip into the crease between the flange and the upper and simultaneously pounding the beveled edge into engagement with the flange by a reciprocating hammer means, or pressing and squeezing it into engagement with the flange by co-operating pressure rolls. In womens shoes, particularly, this flange is delicate and the treatment received by the beating or rolling action of machines heretofore employed is too harsh and tends to distort the flange, stretching it so that after the welting strip is attached it does not lie close to the upper and, accordingly, does not give a pleasing appearance in the finished shoe. In View of the foregoing, it is an object of the present invention to provide a machine for rapidly and effectivly attaching a precoated welting strip to the outturned bottom flange of an Ayrlyte shoe with out subjecting it to the harsh treatment referred to above and in such a manner as to insure a permanent bond.
In the attainment of this object, one feature of the machine comprises means for supporting strip welting having a precoated beveled edge in a position to facilitate attaching the welting to the outturned bottom flange of a shoe. As illustrated, the aforesaid supporting means is constructed and arranged to advance successive portions of the welting with its precoated beveled edge exposed for engagement with the flange of the shoe to the position of attachment to enable the operator continuously to attach the welting to the flange of the shoe by turning the shoe and simultaneously pressing its flange in engagement with the beveled edge of the advancing welting. The supporting means includes spaced members adapted to engage the unattached welting with its beveled edge projecting therefrom and as it is advanced toward the position of attachment, by means provided for this purpose, successive portions of one of the members are caused to move toward the other to squeeze the welting to flatten it and to apply supporting pressure thereto so that when the flange of the shoe it brought into engagement with the beveled edge, the latter will not readily deflect. Cam means is provided for moving the successive portions of the one member toward the other. as the welting is presented to the position of attachment, the cam being constructed thereafter to release the portions and thereby to release the welting from supporting pressure so that it may slip from between the members. During the movementof the successivev portions of the one member toward the other, they are subjected to repeated'bl'ows which tend to still further flatten the welting.
This is effected by -a reciprocating-striker arranged to impart through the cam repeated blows to the'successive portions of the one member. The one member comprises a plurality of independently movablesections between which there are slots or spaces, the sections being mounted to move with the opposite member as a unit. The opposite member is also provided with slots corresponding to the slots between the sections, and another feature of the machine resides in a cutting blade mounted for movement through the slots to sever the attached welting laid about the bottom flange of the shoe from the unattached welting adjacent to that section which grips the welting strip at the time it is to be severed. The
.outting blade is moved into operation at the will of the operator and, in accordance with still another feature or the machine, means is provided for automatically alining the slots between one pair of sections of the holding means withthe knife. As specifically illustrated, the holding means comprises a disk having a recess in one side near its edge the wall of which has radial slots therein, and a plurality of spaced sectors arranged opposite the wall of the recess, thereby to form spaced surfaces. To aline corresponding slots in the walls with the knife, a plunger is provided which is advanced by movement of. the knife toward its severing position to enter the spaces between a pair of teeth on a gear fixed to a shaft which rotates the holding means. The gear has teeth in such number that the spaces between the teeth correspond to the slots between the sectors. Rotation of the gear one way or the other by entrance of the plunger between a pair of teeth produces a corresponding rotation of the holding means, thereby bringing one of the slots into line with the path of movement of the knife.

has been attached to the flange,-the flange is trimmed off even with the underside of the welting strip, a filler is pressed in behind the trimmed flange to levelthe bottom of the shoe, and the outsole is' laid over the'bottom and stitched to the welting strip,as shown at the right side of Fig. 8.
The apparatus'for attaching the welting strip to the untrimmed flange has a hollow frame Ill (Fig. 1) closed at its upper extremity. Near the top of the frame bearings l Zand M are 'formed in thefront and back walls and are'arranged'to're- 'ceive for free rotation a horizontal drive shaft IS the ends of which extend beyond the walls of the frame. "On the front end 'of the shaft Hi there is mounted means l8 for holding the welting at a-predetermined position to facilitatepressing the flange of the shoe into engagement with the beveled'edge of the welting. This means is constructed and arranged frictionally to engage the unattached welting in advance of the predetermined position and to move it to-the predetermined position. As illustrated, this means consists, in part, of a disk fastened to the extreme outer end of the shaft. The inner side of the disk is cut away to form a circumferential recess 22 (Fig. 3) and the outer side is beveled at 24 around its outer edge face, for a purpose 'which will appear'hereinafter. Mounted on the shaft l6 behind the'disk 26 is a hub'26 having a plurality of openings ffirunning parallel to the axis of the shaft which slidably receive stems 30.
'sector shaped heads'32 are formed at the ends of the stems 39 adjacent to the rear'side of the disk 20, the heads extending radially outward from the shaft toward the circumferential edge of the disk.
The faces 34 of the heads 32 are close to the rear sideof thedisk ZO'andbeyond the recessed portion 22 form a circumferential wall 36, which,
with the wall of the recess 22, provide a circumferential groove 33. A welting strip 10 is led from a reel r into the groove 38 the walls of which frictionally engage the opposite sides of the welting strip, holding it with its beveled edge projecting radially from the disk 20, as seen in Fig. 1. By rotation of the disk 26 and hub 26, which is accomplished by rotation of the shaft 16, the welting strip is progressively advanced to the position shown in Fig. 1 where the operator may place the shoe in a position to bring that portion of the flange 1 of the shoe 8 adjacent to the welt crease into engagement with the beveled edge of the welting strip. It is to be observed that the beveling 2 4 at the edge of the disk permits the shoe to be brought close to the projecting welting strip to insure intimate contact Without interference from the disk and provides a guide which, by engagement with the welt crease, will hold the shoe from lateral deviation during the attachment of the welting strip. A pulley 4B freely mounted on the outer end of the shaft l5 and connected by belting 22 to a constantly driven pulley 44 journaled on a countershaft 46 at the base of the frame l9 provides means for rotating the shaft 25. A clutch disk 48 spiined on the shaft l6 and slidable into engagement with the side face of the pulley provides means drivably to connect the pulley '49 to the shaft f6. Movement of the clutch disk 48 is effected by a bell-crank lever 58 one arm 52 of which is forked to engage an annular groove 54 (Fig. 3) formed in the hub 55 of the clutch disk and the other arm 58 of which .is connected by a rod 68 to a'treadle 62' pivotally mounted near the bottom of the frame ill at M. A spring 66 attached at one end to the treadle 62' and at its opposite end to the frame It] holds the treadle up so that normally the clutch 48 is out of engagement with the pulley 40. Rotation of the shaft I 6, and consequently of the Welt strip holding means, is produced by holding the treadle 62 down.
The beveled edge of the welting strip and-that portion of the flange adjacent to the stitch line with which the beveled edge of he welting strip is to be brought into engagement and adhesively united to form a permanent bond are coated with latex prior to bringing them together. In bringing the precoated surfaces together, the only pressure employed to cause permanent adhesion be tween the parts is that exerted by th operator in holding the flange of the shoe upwardly against the beveled edge of the welting strip. To make the most of this pressure, the welting strip must be held rigidly at the exact moment and point at Which the welting strip and flange are brought into intimate contact and yet prior to this time the welting strip must be free enough to permit relative movement in the groove 33 as the holding means rotates, and immediately following the attachment of the welting strip to the flange it must be entirely free from the groove so that it will remain stuck to the flange and will not be pulled away from it by the advancing movement of the shoe. This is effected herein by an annular cam 68 (Fig. '7) mounted on the frame l0 adjacent to the rear ends of the stems 3D, the outer surface of the cam being of such formation that as the hub 25 rotates the end of each stem 30 successively engages the cam surface and progressively is pushed forwardly. The high point of the cam 63 is opposite the Working position so that as each sector-shaped head 32 reaches the working position it will press the welting strip against the inside wall of the recess 22 and rigidly grip it, as illustrated in Fig. 1. It is to be observed that the pressure brought to bear upon the welting by the pressing action of the sectors tends to flatten the welting so that it will conform to the shoe. As shown in Fig. '7, the operating portion ofthe cam 68 extends over an arcuate portion thereof adjacent to its edge, sloping gradually from a low point at I to a high point at I2 and then dropping off suddenly at I4. Thus, the grip on the welting strip is gradually applied as the welting approaches its point of attachment and then is abruptly released so that there is no danger of pulling the welting strip away from the flange. As the stems 38 pass beyond the high point of the cam 58 at E2, they are temporarily free to come and go in the hub 25. As they continue their movement and begin again to approach the low point of the cam at 'IIJ, they are brought under control so that when the ends of the stems reach the point III, they will smoothly engage the cam. To this end, notches I6 are provided near the rear ends of the stems 3D. The notches are picked up as they approach the top of the cam by an inturned rim I8 of an arc-shaped flange SI) fixed to the edge of the cam 53 and extending from a point near the top of the cam (Fig. 6) around the same to a point adjacent to the low point I8 of the cam. The inturned rim I8 slopes toward the low point 15. As will be seen by reference to Fig. 4, the welting strip runs into the groove 38 close to the low point III of the cam. The rim I3 holds the heads 32 prior to the engagement of their stems with the low point It at a sufficient distance from the wall of the recess 22 to permit ready entrance of the welting strip into the groove 38. Frictional engagement of the opposite sides of the welting strip is commenced as soon as the ends of the stems engage the low point of the cam.
The welting strip usually has some irregulari ties in thickness. Moreover, as it is led around corners, for example. the tip and heel end of the shoe, it tends to become wavy. The pressure exerted on the welting by the heads 32 as they are progressively advanced toward the wall of the recess tends to eliminate any irregularities in its thickness and to flatten it out as it passes around curved portions of the shoe. It is desirable, however, to subject the welting strip also to a mild beating action as it is applied to the flange further to flatten the welting. This is suitably accomplished by striking the rear ends of the stems 39 of the sector-shaped heads 32 as they advance the welting strip and during the attachment of the welting strip to the flang. It is to be observed that the blows are imparted to the welting strip alone and not to the flange so that there is no danger of damaging the flange. The blows are delivered to the ends of the stems, through the annular cam 8 which is pivoted for thispurpose at 82 (Fig. l to swing outwardly away from the frame It, by a striker pin 84 one end of which bears against the rear side of the cam. The striker pin 34 is slidably mounted. in a bore 85 formed in the front wall of the frame ID and may be continuously and rapidly vibrated, except during the cutting-off operation, by a cam-operated driver 38. As illustrated, a head 98 is formed on the rear end of the striker pin 86 which abuts the end of the driver 88. The head I!!! is held in contact with a stop pin 9 3, which limits its outward movement, by a spring 52 disposed between the head and the inside wall of the frame If]. The driver 68 is provided with a strap 96 which surrounds an eccentric 33 fixed to a shaft I90 journaled in the side walls of the frame. The shaft I00 carries a pulley III2 (Fig. 3) which is connected by a belt Ill l to the driven pulley 44 also fastened to the shaft 46 at the base of the frame. Near the middle of the driver 88 a link IE6 is connected thereto and to a plunger IIEB which passes through an opening III) in a transverse wall H2 extending across the frame. Below the wall between a flange II4 formed on the lower end of the plunger and the bottom surface of the wall II2 there is placed a spring IIB which pulls the link lilii, and conse quently the driver 88, downwardly out of contact with the head 99, a stop pin Hi3 being provided to limit the downward movement of the plunger. A bell crank I pivoted at I22 to the frame has one arm I24 connected to the plunger W8. A knee pad I25 is mounted at the end of the other arm I26 of the bell crank whereby when pressure is applied to the knee pad the driver 88 may be raised into contact with the head 9%. Thus, the pounding means may be moved into and out of operative position at the will of the operator.
After the welting strip has been attached to the entire bottom flange and simultaneously straightened, it is desirable to sever the attached welting strip from the succeeding unattached welting strip. In order to cut the welting strip without pulling it out of the groove 38 and also to cut it at such a point that the cut end will be in readiness for application to the next shoe, that is, so that there will be no forwardly projecting, unsupported end, the welting strip is severed by passing a knife through it between the sectorshaped head which grips the welting strip at the working point and the preceding head which has just released the welting strip. To this end, radial slots I28 (Fig. 4) are formed in the wall of the recess 22, opposite the spaces between successive sector-shaped heads 32, through which the leading end of a knife I30 (Fig. 2) may be passed. As shown, the knife I3ll is mounted for sliding movement parallel to the shaft I6 in a guideway I32 formed in the front wall of the frame, an outboard bearing I34 being provided to support and guide the forward end of the knife. The knife is advanced at the will of the operator by downward movement of a cam plate I36 (Fig. 1) having a forwardly sloping cam slot I38 which engages a pin I40 carried by the knife. To pull the cam plate downwardly, a link I42 is fastened thereto and to an arm I44 pivoted at I46 to the frame ID, the forward end of the arm being movable in a clockwise direction about the pivot I 46 by a rod I48 connected to a treadle 62 corresponding to the treadle 62 and pivoted to the base of the machine at 64, a spring 66 being provided for holding the treadle in an inoperative position. To make sure that the knife I38 is held in an out-of-the-way position, another spring I50 is provided which is connected to the arm I and to the frame ID, the latter spring assisting in holding the arm in a raised position.
In order that one of the openings between the sectors 32 and a corresponding slot I28 in the wall of the recess 22 may be alined with the knife I3!) as it is advanced to cut the welting strip, means is provided for automatically turning the holding means I8 one way or the other to bring the closest opening and slot in line with the knife. For this purpose a gear I52 is fixed to the shaft I 6. The gear has teeth I54 (Fig. 6) thereon which correspond in number and are spaced similarly to the openings between the sectors 32. Be-
low the gear I52 and movable into meshing engagement therewith is a plunger I55. The plunger I58 is slidably mounted in a central bore I58 formed in a rod I80 which passes through the wall H2 and is pivotally connected at its lower end to the rear end of the arm M4 at I62. A spring I64 is disposed behind the plunger I56 at the bottom of the bore I58 and yieldably supports the plunger for sliding movement therein. Since the rod I6!) is attached to the arm I44, when the latter is rotated in a clockwise direction to advance the knife the plunger I56 will be moved forwardly to engage a space between one set of teeth I54 and thus operates to turn the shaft I and to center one of the openings between the sectors 32 with the advancing knife.
In the operation of the machine, the operator draws the leading end of a welting strip w from the reel r and pushes it edgewise between the walls of the groove 38 formed by the rear face of the recess 22 in the disk and the front faces 34 of the sector-shaped heads 32 at the point where the welting strip is substantially tangent to the bottom of the groove 38 (Fig. 4). The machine is then started by depressing the treadle 62' so that the holding means i 3 rotates, advancing the welting strip to the position shown in Fig. l. The operator then lifts a shoe to bring that portion of the bottom flange adjacent to the stitch line into engagement with the beveled edge of the welting strip. Pressing the flange firmly against the beveled edge, the operator advances the shoe by rotating it, thus progressively attaching the welting strip to the flange. During this time, by pressing inwardly on the knee pad I the welting is flattened by the continuous beating action of the striker pin 84 which, through the cam 68 and stems 33 of the sector-shaped heads 32, impart blows to the rear side of the welting strip. When the welting strip has been led around the entire bottom flange of the shoe, or around such portion of it as is desired, the operator releases the treadle 52, thereby stopping the rotation of the holding means I3, and releases the knee pad I25, thereby withdrawing the striker pin 85 from operation. The knife I38 is then advanced to sever the welting strip b depressing the treadle 62 which simultaneously alines one of the slots in the holding means IS with the advancing knife. This completes the operation and upon release of the treadle 62 the machine is ready for the next operation.
