Definitions

  • This invention relates to machines for use in the manufacture of boots and shoes and particularly to the lasting and nailing type of machines, although some features of the invention are useful also in fastening machines in which no lasting instrumentalities are included.
  • the object of the invention is to expedite the work by the reduction of the number of operations necessary to complete the securing of the upper to the insole.
  • the invention comprises for a lasting machine having a pincer that operates successively on different portions of a shoe upper the combination with the pincer of a plurality ofdevices arranged to insert a plurality of fasteners along the edge of the shoe at each pulling operation of the pincer, and means for rendering one or more of said devices inoperative.
  • a double raceway so that two tacks may be delivered together, and it is preferred to arrange it so that one tack may be delivered and driven centrally with regard to the pincer and the other may be delivered and driven to one side of the pincer although of course the tacks might be driven one on either side of the pincer.
  • the pincer it is usual in this class of machine to give the pincer besides its ordinary upper pulling motion a lateral plaiting movement in order to form the necessary plait at those parts.
  • the invention also comprises the provision of means for simultaneously throwing into action the plaiting motion and preventing the delivery of a fastener from one of the raceways.
  • the race way in use from which the fastener is to be delivered will be, in the case of the preferred construction, the one that is central relatively to the pincer-that is, it will not be the offset one.
  • the raceway in use will vary according to the direction of the plaiting movements of the pincer being preferably upon that side of it which may conveniently be termed the following side.
  • the means for preventing the insertion of one of the fasteners and the means for giving the pincer a plaiting movement may be thrown into and out of operation by the same mechanism and at the same time because as a rule the said preventing means will be used only when the pincer is plaiting at the toe.
  • the said preventing means may be rendered inoperative by devices that are actuated by the movement of the edge gage or bunter into position for operating along the sides.
  • the present invention further comprises the provision for a pincer lasting or like machine of a plurality of fastener drivers and means to vary the spacing between them.
  • this automatic adjustment is obtained from a part of the machine which is adjusted according to the requirement of the work and in the embodiment of the invention about to be described this part of the machine is an edge gage.
  • the shoe bottom rest is improved in such a manner that it will adapt itself more readily to the surface of the insole and hold it more securely for the operation of the machine notwithstanding that the said surface is disposed somewhat out of horizontal relationship to the machine.
  • a work rest constructed according to this improvement also allows for tipping the shoe to raise or lower the work surface at either side of the machine whilevstill maintaining the bottom of the last in firm contact with the rest.
  • This invention can with particular advan tage be applied to a lasting machine equipped with the above described invention in which two tacks are inserted at each operation of the machine during the operation upon certain parts of the work as by its application it is insured that both tacks are driven to a more equal extent.
  • a feature of this new shoe rest or Work support for use in a lasting machine of the hand method type is that it is mounted to swivel laterally for the purpose above set forth.
  • the shoe rest or Work support mounted as above described may also be arranged to swivel at right angles to the swiveling motion first mentioned so as to compensate for angular disposition longitudinally as well as for lateral displacement out of the horizontal.
  • the swiveling action of the rest under the influence of changes in the level of the work surface may be utilized to effect through suitable connections corresponding of the invention.
  • Figure 1 is a side elevation of a machine equipped with the present invention
  • Fig. 2 is a fragmentary view of the reverse side of the machine

  • Fig. 4 is a front View, partly in section, of the tacking devices
  • Fig. 5 is a side sectional elevation of the raceway.
  • the machine comprises a column 2 on which is supported a head 4 that has bearings for the usual cam shaft.
  • This shaft is provided with the usual complement of cams for actuating the pincers, including the updraw cam connected yieldingly to the updraw lever from the front end of which the pincer 5 is suspended; the closing cam which operates through the usual rock shaft, carried in the updraw lever for shutting the aws upon the upper and holding them closed while the pincers are lifted to stretch the upper; and the overdraw cam acting through the stem. of the overdraw yoke for moving the pincer inwardly from the edge of the shoe bottom to carry the pulled upper into position to be fastened.
  • One of the cams on the shaft also has the usual cam groove for oscillating the lever 6 which continuously actuates the rock shaft 8, said rock shaft having a head in which is adjustable a driver for moving the pincer laterally and turning it to effect the plaiting movements which are needed for disposing of the surplus stock carried over the shoe bottom by the pincer at the toe and sometimes at other parts of the shoe.
  • This driver is adjusted by the same mechanism as that shown in said patent, including the sleeve 10 which slides on the rock shaft and is moved by a knee lever connected to a vertical pivot attached to the post 2. All of these parts of the machine may be substantially as described and shown in full in said patent and further description is therefore unnecessary in this specification.
  • the machine has in accordance with this invention, a double raceway 20 having two tack chutes 21 and 22 and associated with each of these chutes are the usual or suitable devices for separating and delivering tacks from each.
  • the tacks are delivered to two tack holders 24, 25 the former of which is rigidly connected with the reciprocating tack block supporting slide 26 of the commercial machine which is arranged and actuated by a cam on the cam shaft, as is fully disclosed in said prior patent.
  • the tack holder 24 has on its left hand side, Fig. 3, a lateral projection with which the tack holder 25 is pivotally connected for ZLdJHStment from and toward the holder 24 about a vertical axis.
  • the tack holders are formed on their lower faces to wipe or rub over the shoe bottom during their forward stroke for pressing the upper into position to be tacked and because of this function these tack holders are sometimes referred to as reciprocating wipers.
  • the tack holder 24 may have, as shown in Fig. 3, an end plate 28 which constitutes its most advanced upper rubbing portion and which is extended laterally across the space between the two tack holders and across the front end of the holder 25 so as to present a continuous upper wiping surface at the front end of the two holders.
  • the tack driver bar 30 is movable endwise in its guideway for driving tacks as and by the means described in said patent and has at its lower end a driver 32 cooperating with the tack holder 24.
  • the driver bar has a lateral projection 34, Fig. 4, upon which is pivoted an auxiliary driver bar 35 having a driver 36 cooperating with the tack holder 25, the pivotal connection between the bars 30 and 35 permitting the latter bar to be properly positioned laterally for alinement with the driver passage in the tack holder 25.
  • a tack arresting finger 40 which has one end located over the lowermost tack in the tack chute 21 and which is mounted for pivotal movement about a connection with the machine frame at 41 to engage said tack and thereby prevent further delivery of tacks from the chute 21.
  • the second end of the finger 40 depends into the path of the cam slide 42 in the right hand lateral face of which is a depression 43 between two high portions or surfaces.
  • the spring 39 presses the finger toward the cam slide.
  • the cam slide is connected by a vertical pivot 44 and a spring pressed friction pin 45 with a rack bar 46.
  • the rack bar is engaged by a segment toothed end of a lever 47 which comprises the two arms of the rock shaft 48,0ne arm being located substantially above the other arm as appears from Fig. 1, and being connected by a vertical stud 49 to a lateral projection from the fork 50 which is attached to the upper end of the usual rocker of the machine which is connected downwardly to the knee lever, all as fully shown in said prior patent.
  • the purpose of this knee lever, rocker and fork, as fully described and illustrated in said patent, is to shift the sleeve 10 lengthwise of. the rock shaft 8 for adjusting the'head of the rock shaft or the driver through which the extent and direction of the upper plaiting movements are controlled.
  • This mechanism being well known and not of importance in connection with the present invention are not necessary here to describe.
  • the position of the finger 40 is controlled by the plaiter control.
  • the cam slide is so arranged with relation to the finger 40 that when no plaiting movement is being effected the lower end of the finger stands in or opposite to the depression 43 in the head of said slide but when the plaiting mechanism is thrown into action by turning the lever in one direction or the other, as may be required for plaiting one side or the other of the toe of the shoe, the cam slide will be shifted to bring one or the other of the high portions of its head into engagement with the finger 40 and rock the latter into position and arrest the delivery of tacks from the chute 21.
  • the chute 22 and the tack holder 24and driver 32 are positioned centrally with relation to the pincer while the chute 21, holder 25 and driver 36 are offset with relation to the pincer and that it is the delivery of the offset tack which is discontinued when the plaiting mechanism is rendered operative.
  • This arrangement provides one tack only for each operation of the pincers around the toe of the shoe and for driving that tack centrally with relation to the plait formed by the pincers as is known in the use of this type of machine, while two tacks are driven for each operation of the pincers when the plaiting mechanism is not in use.
  • the offset tack is advantageously on the following side of the pincers, that is, the direction of progress is such that the ofiset tack is driven in the space between the central tack and the last tack inserted by the previous cycle of operation of the machine.
  • the pivotal connection 44, 45 permits a limited swinging movement of the cam slide 42 on the rackbar 46 which is sufficientto render the cam slide ineffective for rocking the finger 40 and stopping the delivery of tacks when no supplemental means is operative for preventing the relative pivotal movement of the cam slide and rack bar.
  • the usual bunter edge rest 60 of the machine which slides forwardly and backwardly in a fixed track as indicated by full and dotted lines in Fig. 1 has a spring pressed pin 62 which in the forward or operative position of the bunter edge rest engages a depending flange 63 of the cam slide 42 and holds it out toward the lower end of the finger 40 as is clearly shown in Fig. 4.
  • the bunter edge which the holder 25 receives its tack.
  • the thick edge gage or rest (30 is also herein connected to devices which control the lateral position of the tack holder 25 and driver 36 with relation to the holder 24 and driver 82 thereby controlling the spacing of the two tacks.
  • the thick gage carrier has rack teeth 65 on an upper edge face, or a rack bar is attached to said gage carrier, and the teeth mesh with a pinion 66 which is fast on a shaft 68 that turns in the machine head and has a threaded end as shown best in Fig.
  • the threaded end of the shaft turns in a nut that is secured to the rear end of a leverr'O the hub of which turns in bearings in the machine head and the front arm of which is formed with a slot that extends from the center of oscillation of the lever radially and is as long as, or longer than, the usual length of reciprocatory movement of the tack holders 24-. 25.
  • tack holder 24 There is erected on the side of the tack holder 24:, or on the tack block supporting slide 26, bearing for a vertical rock shaft 75 the lower end of which shaft may conveniently serve the pivoted carrier upon which the tack holder 25 is fastened for movement laterally from and toward the holder 24.
  • the lower arm of the rock shaft extends backwardly and' has a stud standing in the slot in the lever 70 whereby, as the tack holder and its supporting slide are reciprocated in and out, the rock shaft is turned in proportion to the angularity of the slot in the lever 70 with relation to the path of the tack holder 24 and supporting slide 26.
  • the location of the slot in lever 70 by which it extends from the axis of the lever provides for returning the tack block 25 always to a predetermined lateral relation to the tack block 24 and to the tack raceway and the chute 21 from This tack receiving position will not be altered by any adjustment of the lever 70 by the edge gage and this is an important feature of the construction.
  • An upper arm of the rock shaft engages the head of the sliding block which is normally held against said arm by a spring pressed plunger 82.
  • the block 80 has a forwardly projecting stud carrying a roll that stands in a groove in the rear face of the driver bar 35. Through this connection with the driver bar said bar is swung about its pivotal connection with the bar 30 and adjusted laterally in company with the tack holder 25.
  • the tack driver 36 is adjusted in company with its tack holder
  • This arrangement provides for driving the tacks relatively closer together at the heel seat than at the sides of the shoe.
  • the spacing of the tacks may be initially determined by adjustment of the shaft 68 with relation to the pinion 66.
  • the pinion may be held normally fast on the shaft by a screw 67 which can be loosened to permit movement of the shaft independently of the pinion.
  • the shoe bottom rest is carried by a bracket located in front of the pincers and comprises an arm. which is formed with a bearing for a rod 92 that can turn about an approximately horizontal axis extending from front to back of the machine.
  • the bottom rest foot 94 On the inner end of this rod the bottom rest foot 94 is mounted to turn per and a tacker cooperating therewith to about a horizontal axis 95 which extends fasten the pulled upper, said machine havtransversely of the first mentioned axis. I ing provision for adjustment to cause the This mounting for the bottom rest foot per Inits the foot to turn in any direction necessary to adapt itself to the level of the work or the angular position which the particular portion of the work engaged by it may occupy. This arrangement provides for such relative adjusting movement of the rest and two drivers as enables the operator to obtain insertion of the two tacks from the tack holders to the same depth.
  • the thick edge gage When the shanks and sides of the shoe have been lasted the thick edge gage will be returned to its operative position. This adj ustment will change the angular position of the lever and cause the tacks to be spaced nearer together. It will also, by means of the plunger 62, press the cam slide 42 into position to cause delivery of tacks from the chute 21 to be stopped whenever the plaiting mechanism is thrown into operation.
  • the operator may obtain wide or narrow spacing of the tacks as may be best suited to the portion of the shoe which he is lasting and may discontinue the insertion of one of the tacks while plaiting the toe without being obliged to give any special attention to these adjustments or to make any manipulation of the machine in addition to those to which he is accustomed.

LASTING AND TACKING MACHINE.
Specification of Letters Patent.
Patented Oct. 31, 1911.
Application filed March 15, 1,911. Serial No. 614,607.
To all whom it may concern:
Be it known that I, ARTHUR BATES, a subject of the King of Great Britain, residing at Leicester, Leicestershire, England, have invented certain Improvements in Lasting and Tacking Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to machines for use in the manufacture of boots and shoes and particularly to the lasting and nailing type of machines, although some features of the invention are useful also in fastening machines in which no lasting instrumentalities are included.
The invention will be explained in connection with a single pincer lasting machine of the type shown in United States Letters Patent No. 584,744.
The object of the invention is to expedite the work by the reduction of the number of operations necessary to complete the securing of the upper to the insole.
In a pincer-lasting machine it has been customary to drive one tack after each upper pulling operation of the pincer and it is now proposed that either one or more than one tack should at the will of the operator be driven to each upper pulling operation. This is particularly advantageous in that type of machine known as a single pincer-lasting machine for in this case the pincer is caused to grip the upper and move it over the shoe bottom where it is tacked and to repeat this operation progressively around the upper until the whole has been pulled and secured. Hence, in such a machine, at certain parts of the boot or shoe the space between the two successive grips of the pincer may be widened by the use of the present invention and consequently the time occupied in lasting the complete shoe may be reduced considerably.
Accordingly the invention comprises for a lasting machine having a pincer that operates successively on different portions of a shoe upper the combination with the pincer of a plurality ofdevices arranged to insert a plurality of fasteners along the edge of the shoe at each pulling operation of the pincer, and means for rendering one or more of said devices inoperative.
According to one embodiment of this invention in a single pincer machine it is proposed to use a double raceway so that two tacks may be delivered together, and it is preferred to arrange it so that one tack may be delivered and driven centrally with regard to the pincer and the other may be delivered and driven to one side of the pincer although of course the tacks might be driven one on either side of the pincer. At the toe it is usual in this class of machine to give the pincer besides its ordinary upper pulling motion a lateral plaiting movement in order to form the necessary plait at those parts. hen this is done it will be frequently unnecessary or inadvisable to drive a tack at more than one place, and consequently the invention also comprises the provision of means for simultaneously throwing into action the plaiting motion and preventing the delivery of a fastener from one of the raceways. It will be obvious that the race way in use from which the fastener is to be delivered will be, in the case of the preferred construction, the one that is central relatively to the pincer-that is, it will not be the offset one. In the case where the nails are delivered anddriven one on either side of the pincer the raceway in use will vary according to the direction of the plaiting movements of the pincer being preferably upon that side of it which may conveniently be termed the following side.
Conveniently the means for preventing the insertion of one of the fasteners and the means for giving the pincer a plaiting movement may be thrown into and out of operation by the same mechanism and at the same time because as a rule the said preventing means will be used only when the pincer is plaiting at the toe.
In some classes of work it may be desired to plait at portions of the side and still use the two tacks and in that case the said preventing means may be rendered inoperative by devices that are actuated by the movement of the edge gage or bunter into position for operating along the sides.
It has been found that in certain cases it is advisable that the spacing between adjacent fasteners should be varied, and this is particularly the case at the heel and sides of the shoe.
Accordingly the present invention further comprises the provision for a pincer lasting or like machine of a plurality of fastener drivers and means to vary the spacing between them.
According to a further feature there may be combined with'these relatively adjustable drivers a plurality of fastener carriers or throats and means to vary the spacing between them. Conveniently there may be operative connections such that adjustment between the drivers efiects a corresponding adjustment between the throats or vice versa.
According to one arrangement of the invention there may be automatic adjustment between the drivers and if desired there may also be automatic adjustment between the throats, these adjustments being according to the requirements of the work or that part of the work which is being dealt with; and in a convenient construction this automatic adjustment is obtained from a part of the machine which is adjusted according to the requirement of the work and in the embodiment of the invention about to be described this part of the machine is an edge gage.
As herein shown the shoe bottom rest is improved in such a manner that it will adapt itself more readily to the surface of the insole and hold it more securely for the operation of the machine notwithstanding that the said surface is disposed somewhat out of horizontal relationship to the machine. A work rest constructed according to this improvement also allows for tipping the shoe to raise or lower the work surface at either side of the machine whilevstill maintaining the bottom of the last in firm contact with the rest.
This invention can with particular advan tage be applied to a lasting machine equipped with the above described invention in which two tacks are inserted at each operation of the machine during the operation upon certain parts of the work as by its application it is insured that both tacks are driven to a more equal extent. Accordingly a feature of this new shoe rest or Work support for use in a lasting machine of the hand method type is that it is mounted to swivel laterally for the purpose above set forth. Conveniently the shoe rest or Work support mounted as above described may also be arranged to swivel at right angles to the swiveling motion first mentioned so as to compensate for angular disposition longitudinally as well as for lateral displacement out of the horizontal. The swiveling action of the rest under the influence of changes in the level of the work surface may be utilized to effect through suitable connections corresponding of the invention.
Figure 1 is a side elevation of a machine equipped with the present invention; Fig. 2 is a fragmentary view of the reverse side of the machine; Fig. 8 is a plan view, partly in section, of certain parts shown in Figs. 1 and 2; Fig. 4 is a front View, partly in section, of the tacking devices; Fig. 5 is a side sectional elevation of the raceway.
The machine comprises a column 2 on which is supported a head 4 that has bearings for the usual cam shaft. This shaft is provided with the usual complement of cams for actuating the pincers, including the updraw cam connected yieldingly to the updraw lever from the front end of which the pincer 5 is suspended; the closing cam which operates through the usual rock shaft, carried in the updraw lever for shutting the aws upon the upper and holding them closed while the pincers are lifted to stretch the upper; and the overdraw cam acting through the stem. of the overdraw yoke for moving the pincer inwardly from the edge of the shoe bottom to carry the pulled upper into position to be fastened. One of the cams on the shaft also has the usual cam groove for oscillating the lever 6 which continuously actuates the rock shaft 8, said rock shaft having a head in which is adjustable a driver for moving the pincer laterally and turning it to effect the plaiting movements which are needed for disposing of the surplus stock carried over the shoe bottom by the pincer at the toe and sometimes at other parts of the shoe. This driver is adjusted by the same mechanism as that shown in said patent, including the sleeve 10 which slides on the rock shaft and is moved by a knee lever connected to a vertical pivot attached to the post 2. All of these parts of the machine may be substantially as described and shown in full in said patent and further description is therefore unnecessary in this specification.
The machine has in accordance with this invention, a double raceway 20 having two tack chutes 21 and 22 and associated with each of these chutes are the usual or suitable devices for separating and delivering tacks from each. The tacks are delivered to two tack holders 24, 25 the former of which is rigidly connected with the reciprocating tack block supporting slide 26 of the commercial machine which is arranged and actuated by a cam on the cam shaft, as is fully disclosed in said prior patent. The tack holder 24 has on its left hand side, Fig. 3, a lateral projection with which the tack holder 25 is pivotally connected for ZLdJHStment from and toward the holder 24 about a vertical axis. The tack holders are formed on their lower faces to wipe or rub over the shoe bottom during their forward stroke for pressing the upper into position to be tacked and because of this function these tack holders are sometimes referred to as reciprocating wipers. The tack holder 24 may have, as shown in Fig. 3, an end plate 28 which constitutes its most advanced upper rubbing portion and which is extended laterally across the space between the two tack holders and across the front end of the holder 25 so as to present a continuous upper wiping surface at the front end of the two holders.
The tack driver bar 30 is movable endwise in its guideway for driving tacks as and by the means described in said patent and has at its lower end a driver 32 cooperating with the tack holder 24. The driver bar has a lateral projection 34, Fig. 4, upon which is pivoted an auxiliary driver bar 35 having a driver 36 cooperating with the tack holder 25, the pivotal connection between the bars 30 and 35 permitting the latter bar to be properly positioned laterally for alinement with the driver passage in the tack holder 25.
As appears from Figs. 1, 4 and 5, there is a tack arresting finger 40 which has one end located over the lowermost tack in the tack chute 21 and which is mounted for pivotal movement about a connection with the machine frame at 41 to engage said tack and thereby prevent further delivery of tacks from the chute 21. The second end of the finger 40 depends into the path of the cam slide 42 in the right hand lateral face of which is a depression 43 between two high portions or surfaces. The spring 39 presses the finger toward the cam slide. The cam slide is connected by a vertical pivot 44 and a spring pressed friction pin 45 with a rack bar 46. The rack bar is engaged by a segment toothed end of a lever 47 which comprises the two arms of the rock shaft 48,0ne arm being located substantially above the other arm as appears from Fig. 1, and being connected by a vertical stud 49 to a lateral projection from the fork 50 which is attached to the upper end of the usual rocker of the machine which is connected downwardly to the knee lever, all as fully shown in said prior patent. The purpose of this knee lever, rocker and fork, as fully described and illustrated in said patent, is to shift the sleeve 10 lengthwise of. the rock shaft 8 for adjusting the'head of the rock shaft or the driver through which the extent and direction of the upper plaiting movements are controlled. The details of this mechanism being well known and not of importance in connection with the present invention are not necessary here to describe.
By reason of the connections from the fork 50 to the cam slide 42 it will be understood that the position of the finger 40 is controlled by the plaiter control. The cam slide is so arranged with relation to the finger 40 that when no plaiting movement is being effected the lower end of the finger stands in or opposite to the depression 43 in the head of said slide but when the plaiting mechanism is thrown into action by turning the lever in one direction or the other, as may be required for plaiting one side or the other of the toe of the shoe, the cam slide will be shifted to bring one or the other of the high portions of its head into engagement with the finger 40 and rock the latter into position and arrest the delivery of tacks from the chute 21. It may be here noted that the chute 22 and the tack holder 24and driver 32 are positioned centrally with relation to the pincer while the chute 21, holder 25 and driver 36 are offset with relation to the pincer and that it is the delivery of the offset tack which is discontinued when the plaiting mechanism is rendered operative. This arrangement provides one tack only for each operation of the pincers around the toe of the shoe and for driving that tack centrally with relation to the plait formed by the pincers as is known in the use of this type of machine, while two tacks are driven for each operation of the pincers when the plaiting mechanism is not in use. Considered with reference to the direction of progress of lasting, the offset tack is advantageously on the following side of the pincers, that is, the direction of progress is such that the ofiset tack is driven in the space between the central tack and the last tack inserted by the previous cycle of operation of the machine.
The pivotal connection 44, 45 permits a limited swinging movement of the cam slide 42 on the rackbar 46 which is sufficientto render the cam slide ineffective for rocking the finger 40 and stopping the delivery of tacks when no supplemental means is operative for preventing the relative pivotal movement of the cam slide and rack bar. For the purpose of providing this means the usual bunter edge rest 60 of the machine which slides forwardly and backwardly in a fixed track as indicated by full and dotted lines in Fig. 1 has a spring pressed pin 62 which in the forward or operative position of the bunter edge rest engages a depending flange 63 of the cam slide 42 and holds it out toward the lower end of the finger 40 as is clearly shown in Fig. 4. The bunter edge which the holder 25 receives its tack.
rest occupies its advanced operative position l during the lasting of the toe and of the heel but this rest, on account of its thickness, must be moved backwardly into an inoperative position in order to allow the shoe to be so presented to the machine that the shank can be lasted. As a matter of practice, operators shift the thick edge rest to its inoperative position for lasting the shank and also the sides and in doing so expose for use the thin edge rest 61 which is immovably supported directly over the thick rest and is so shaped that it offers no obstruction to the presentation of the shank and side portions of the shoe to the machine. It will now be seen that while lasting the shank and sides of the shoe the cam slide 4L2 is not held to its work and that therefore the plaiting mechanism can be thrown into operation as is sometimes desired in lasting around the forepart or corner of a deeply incurved shank, without stopping the delivery of the offset or second tack. The thick edge gage or rest (30 is also herein connected to devices which control the lateral position of the tack holder 25 and driver 36 with relation to the holder 24 and driver 82 thereby controlling the spacing of the two tacks. To this end the thick gage carrier has rack teeth 65 on an upper edge face, or a rack bar is attached to said gage carrier, and the teeth mesh with a pinion 66 which is fast on a shaft 68 that turns in the machine head and has a threaded end as shown best in Fig. The threaded end of the shaft turns in a nut that is secured to the rear end of a leverr'O the hub of which turns in bearings in the machine head and the front arm of which is formed with a slot that extends from the center of oscillation of the lever radially and is as long as, or longer than, the usual length of reciprocatory movement of the tack holders 24-. 25. There is erected on the side of the tack holder 24:, or on the tack block supporting slide 26, bearing for a vertical rock shaft 75 the lower end of which shaft may conveniently serve the pivoted carrier upon which the tack holder 25 is fastened for movement laterally from and toward the holder 24. The lower arm of the rock shaft extends backwardly and' has a stud standing in the slot in the lever 70 whereby, as the tack holder and its supporting slide are reciprocated in and out, the rock shaft is turned in proportion to the angularity of the slot in the lever 70 with relation to the path of the tack holder 24 and supporting slide 26. The location of the slot in lever 70 by which it extends from the axis of the lever provides for returning the tack block 25 always to a predetermined lateral relation to the tack block 24 and to the tack raceway and the chute 21 from This tack receiving position will not be altered by any adjustment of the lever 70 by the edge gage and this is an important feature of the construction. An upper arm of the rock shaft engages the head of the sliding block which is normally held against said arm by a spring pressed plunger 82. The block 80 has a forwardly projecting stud carrying a roll that stands in a groove in the rear face of the driver bar 35. Through this connection with the driver bar said bar is swung about its pivotal connection with the bar 30 and adjusted laterally in company with the tack holder 25.
The above described arrangements are such that when the thick edge rest occupies its retracted position shown in dotted lines in Fig. l, which is the position for lasting the shank and sides of the shoe, and is that position in which two tacks are driven uninterruptedly without regard to the plaiting mechanism, as above described, the lever 70 will occupy its position of greatest angularity with reference to the direction of reciprocation of the tack block 24 and slide 26. The tack block 25 will then advance in each operation of the machine from its constant tack receiving position under chute 21 and be moved toward the left in Figs. 3 and 41- to a position for driving the offset tack spaced widely from the tack that is inserted from holder 241-. It will then return to its constant tack receiving position, the roll on the lower arm of the rock shaft 75 standing centrally with relation to the axis of the lever- 70. When the thick edge gage is adjusted to its forward position for lasting the heel of the shoe it will effect through rack teeth (35, pinion 66 and screw 68 an adjustment of the lever '70 to position said lever with its slotted arm more nearly parallel with the direction of reciprocation of the tack holder 24 and slide 26 and therefore, while the edge rest remains forward, the rock shaft 75 will receive a short oscillation and the tack holder will thereafter be spaced in its tack driving position at a less distance than formerly from the holder 24. Through the upper arm of the rock shaft 75 the tack driver 36 is adjusted in company with its tack holder This arrangement provides for driving the tacks relatively closer together at the heel seat than at the sides of the shoe. The spacing of the tacks may be initially determined by adjustment of the shaft 68 with relation to the pinion 66. For this purpose the pinion may be held normally fast on the shaft by a screw 67 which can be loosened to permit movement of the shaft independently of the pinion. The shoe bottom rest is carried by a bracket located in front of the pincers and comprises an arm. which is formed with a bearing for a rod 92 that can turn about an approximately horizontal axis extending from front to back of the machine.
On the inner end of this rod the bottom rest foot 94 is mounted to turn per and a tacker cooperating therewith to about a horizontal axis 95 which extends fasten the pulled upper, said machine havtransversely of the first mentioned axis. I ing provision for adjustment to cause the This mounting for the bottom rest foot per Inits the foot to turn in any direction necessary to adapt itself to the level of the work or the angular position which the particular portion of the work engaged by it may occupy. This arrangement provides for such relative adjusting movement of the rest and two drivers as enables the operator to obtain insertion of the two tacks from the tack holders to the same depth.
In the use of the machine the operator will proceed in accordance with his usual custom in lasting shoes upon this well known commercial type of machine. Ordinarily the shanks and sides are lasted first and for this purpose the thick edge rest is pushed back to expose the thin edge rest. By this adjustment of the thick edge rest the tack holders and drivers are spaced wide apart and the plunger 62 is withdrawn from the cam slide 412. The machine then proceeds to drive after each pulling movement of the pincer, two tacks, one of which is located centrally with relation to the pincer and the other of which is offset laterally therefrom. The insertion of the offset tack will not be interrupted by throwing the plaiting mechanism into use at any time that that may be needed. When the shanks and sides of the shoe have been lasted the thick edge gage will be returned to its operative position. This adj ustment will change the angular position of the lever and cause the tacks to be spaced nearer together. It will also, by means of the plunger 62, press the cam slide 42 into position to cause delivery of tacks from the chute 21 to be stopped whenever the plaiting mechanism is thrown into operation. It is a very advantageous characteristic of the described construction that the operator may obtain wide or narrow spacing of the tacks as may be best suited to the portion of the shoe which he is lasting and may discontinue the insertion of one of the tacks while plaiting the toe without being obliged to give any special attention to these adjustments or to make any manipulation of the machine in addition to those to which he is accustomed. He is also enabled by the driving of two tacks for each operation of the pincers to last the sides and the heel of the shoe by a substantially smaller number of machine cycles than heretofore and therefore in a materially shorter time than is required by machines not equipped with this invention.
