This invention relates to lasting machines of the type which operate progressively in a'step-by-step manner upon the shoe.

In `machines of this type al gripper is actuated to grip orpull andupdraw the upper material and to overdraw orl lay it. upon the insole, and a Wiper is given movement to en-v gage` the upperV material and Wipe it into lasted position upon thel insole, Thejupper material is secured in such position bytacks Which are fed intoL a tack pocketin the Wiper prior to each operative movement thereof and are driven by tack driving means at the,y conclusion of the Wiper advance Suitable gauges are provided for locating the shoe in the proper transverse position with respect to the instrumentalities of lthe machine. Q11 account of the diffe-rence in the contour of the last at various points in its periphery, ithas been the practice toemp-loya thin edge gauge.

at some parts of the shoe and athickcr bunteredge gauge at; others., llllherev the contour of the last Will permit, the operator prefers to use the bunter gauge because its more extended face is Veasieryto nd and follovv with the shoe and because it. is also. effective in holding in position the; upper/material as updrawn by the gripper. i l v Y Machines of th's type are also provided With mechanism for presenting either longor short tacks.v The added4 thickness ofthe upper material supplied by the toe stiffener makes it desirable to employ long tacks; at this part of the shoe and the same is true Where the thickness of the insole material is increased by a reinforcement., On the other hand, good lasting requires the use ofv short tac-ks in lhe forepart of the shoe.` In machines of this, type asl heretofore constructed,

the edge gauges have beenv sorelated tothe tacking mechanism that. only certain combinations of gauge. and tack supplyhave been available. For example, in such machines it is possible to supply long tacks only when the bunter gauge is operative and this has prevented the employment of long; tacks in a reinforced shank Where they are otherwise desirable. From one' standpoint, my invention consists in a lasting machine having tacksupplymg and gauge. mechanismr organized topermit a greater iiexibility of:correlation` Y than heretofore, so that the operator may at will' .in the lasting Operation, emplcy either short or long tacks with one, 01T the other of the gauges. In a more specific aspect, my invention provides. for thel first time an organized machine having an autos. matically shifting bunter gauge organized to permit the employment of' long tacl'rs',y While the bunter gaugeis maintained infre?. tracted position and the thin edge., gauge iseiiective. Y 'i My invention contemplates also novel mechanism for: controlling the presentation of the bunter gauge andk `of the tack rafQeWays such that the'V operator may secure, @Oliveniently, and Without interrupting the lasting operation, VWhatever combination of" gauge and tack delivery he may desire in the par-, ticular part of the shoe which he is present-` ing'to the machine inlasting position. This, I accomplish in the machine Vherein shown by treadle, and mechanism so.v designedthat one;

depression and release of the ltreadle Willen-- ganize the machine for lasting with SliQrtA tacks and the bunter retracted so. that: the thin, edge gauge is effective; a4 second depresisenV and release of the treadle Will organize lthe' machine for lasting with long taClS. Wthfthe bunter gauge effective; While. aI continued depression of the treadle will organize the machine for lasting with long tacks withfthe:L bunter retractedand the thin edge gauge ef?k ective; and iinally,the release 'of the treaClle after such continued holding ,will organize the machine for lasting with shorty tacks with bunter retracted. f

. Asherein shown, I accomplish the desiredA results by utilizing a power-driven part, of, the machine as an actuator for la bunter shift?. ing member and for a raceway shifting mm? ber. Mechanism is interposed between the actuator and these shifting members which: maybe eiiectively connected to the actuatorin any cycle of the lasting machine selected by the operator, and When so. connected the shifting members are moved,y tending to'sliiiit; both the raccWfayand thebunter-,IOm thepof, sitions which theythen occupy. vThe actual movement of both shifting members, however, is under manual control, as by a treadle, so that the operator may delay the shifting of the bunter gauge or the raceway for any desired number of lasting cycles, during which the machine will continue to operate without change of conditions.

As herein shown, safety means are provided for preventing the establishment of an effective connection with the power-operated actuator except when the parts of the lasting machine are properly positioned for the operation of the parts affected thereby. For example, the position of the raceway should not be changed while the tack separator is open, and this contingency is prevented by safety mechanism which prevents the full operation of the treadle control mechanism of the machine except when the separator is closed.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of .illustration and shown in the accompanying drawings, in which Fig. 1 is a view of the machine in side elevation;

The general organization of the machine is best shown in Fig. 1 where a head 10 is represented as mounted in the upper end of a column l1, of which only a portion is shown. Journaled in the head 10 is a horizontal shaft 12 provided with a driving pulley 13 at its rear end and carrying the cams from which the operative movements of the machine are derived.

.The instrumentalities of the machine will be briefly referred to, but since individually they correspond to similar parts of the wellk'nown hand method lasting machine no de-k tailed description is necessary here. A gripper 14 is given the usual closing, updrawing and overdrawing movements for engaging the upper stock and carrying it over the bottom of the last. The shoe bottom is held against a fixed but adjustable rest 15 with its side positioned against one or the other of two edge gauge, a thin edge gauge 16 or a thick edge gauge or bunter gauge 17. A. reciprocat- ,ing wiper 18 is provided to wipe the tensioned upper into lasted position upon the'shoe bottom and atack is fed in each cycle of the machine from one or the other of two raceway channels 19 and 2O to a pocket in the wiper by which it is carried into position to be driven by a driver 21.

rl`he wiper 18 is carried in the forward end of a slide 43 mounted in a horizontal guideway formed in the machine head 10. The slide has an upwardly extending arm provided with a cam roll 44 arranged to run in a cam 45 on the shaft 12, the cam being shaped to impart a complete reciprocationv to the slide in each cycle of the machine. Beside operating the wiper 18 to wipe the stock over the bottom of the last and presenting a tack in driving position, the slide 43 is utilized to actuate other mechanisms, as will appear hereinafter.

The gripper 14 isI carried at the lower end of a gripper bar 30 which is mounted at its upper end in a forked lever 29 pivotally mounted upon a transverse stud 28 for vertical oscillation to give the gripper the required updrawing movement. The gripper bar is controlled at itsr lower end by a train of mechanism actuated by a cam 32 on the shaft 12 to give the gripper the required overdrawing movement. An auxiliary horizontal shaft 33l is connected to the gripper bar through a vertical lever 34 and a rack, not shown, and is rocked by connections with the shaft 12 to impart a twisting movement tov the gripper and this is controlled by the operator through the vertical shaft 27, Vthe yoke 25 and collar -26 on the shaft 33, all as shown in my prior Patent No. 1,623,135, granted April 5, 1927.

rlhe driver 21 is set in the lower end of a driver bar 42 arranged to slide in a driver bar carrier 40. The carrier is ournaled to swing on trunnions 41, one of which is vshown in Fig. l. The slide 43 is provided at its forward end wth an adjustablestop screw 46 which, as the slide is advanced, engages the driver bar carrier 40 and swings it forwardly over the shoe bottom and positions the driver in line with and above the tack pocket of the wiper 18 so that, when tripped, the driver will act to drive the tack through the pocket into theshoe.

In Figs. 1 and 3 the machine is shown with its parts located atan intermediate position inthe cycle of the machine. The gripper 14 is represented as having closed upon the stock, completed its updrawing movement and substantially completed its outward overdrawing movement. The driver 21 has been lifted toits uppermost position and has been moved outwardly with the wiper 16 as the latter advances from its tack-receiving position, which is in lineV wit-h and beneath the passage in the separator 50. The raceway has been moved to bring the channel 19 for short j tacks` intoA register with a tack passage 51 in the separator. With the parts in the position shown in these figures, the machine. will re-. peat without variation its usual functions,

delivering short tacks from the raceway.

Proceeding now to a description of the mechanism with which the present invention is more particularly concernedit will be understood first that the raceway includes two raceway channels 19 and 2O andthat these may be included in one raceway member or arator 50., In the machine herein illust-rated,

both channels are t'ormedin a single raceway member and this is pivotally mounted at a point remote from its deliveryvend so that in the limited movement imparted thereto the ends of the

channels

19 and 20 travel in a sub stantially straight path., Shorttacks are supplied to the outer-channel 19 and long tacks to the inner channel 2O from tack pots of usual construction. Movement is imparted to the racewayby a link 52 having an adj ustable eXtensionS which makes a ball and socket connection with the raceway member.

The link 52 at its Vother end is pivotally connected to a yoke 54 which is suspended upon a screw 55 threaded into an arm 56.` The arm 56 is loosely mounted upon a vvertical pin 57r projecting upwardly from. a stationary bracket 58 secured to or forming a part of the 1 fra-me of the machine head. The arm 56is provided with al horizontallyV extending socket for the reception ot a compression.

spring 59 which presses always against vthe end of the yoke 54 and holds it in Contact with the back of the pin 55,'as shown best yin Fig.

6. Near the. outer end of the arm 56 is a downwardly projecting pin 60 to which is securedone end of a tension spring 61, the other end being secured to an upstanding pin 62set in a bell crank lever 63 mounted to swing about the pin 57 upon which the arm 56 is also journaled. The spring 61l thus tends always to swing the varm 56 ina counter clockwise direction, moving the link 52v to'- ward the right, as seen in Fig. 5, and holding the raceway channel 19 ifo-r short tacks in. registration with the tack passage 51 of the separator. Y Y

The position of the arm 56 in swinging in a counter clockwise direction under the-actuation of the spring- 61 is determined b ya yoke having an upper arm 70, a lower arm71 and a boss 72 projecting from its intermediate portion whichengages a lug 49 projecting from the hub of the arm 56. This is best shown in Fig. 8, from which it will also be.v apparent that the arms 70 and 71 of the yoke are journale'd to swing upon the vertical pin 57, the upper arm 70 of the yoke being locat. ed immediately above the arm 56 to which the link 52 is connected.

A pin 7 3 projects upwardly from the upper arm 70 of the yoke and constitutes a pivotal connection with a horizontally disposed yokel 74, best shown in Fig. 5. The yoke 74 straddles the upright shaft 27 and is guided in its movement by a roller 75 arranged to turn freely on the vertical shaft. Upon the lower face of the yoke 74 are arranged twospaced cam rolls 76 and 7 7 whichengage between them a three-arm `or star cam 7 8 which is also ournaled upon the vertical shaft 27. The rotation of the cam 7.8 is effected a stepA at a time and causes the yoke 74 to move back and fcrth and, consequently, to swing the yoke 7 0 about the anis of the pin 57. lt will be understood, however, that the yoke 74-is notintermittently oscillated in eachv cycle of the machine but remains at rest except when the operator takes appropriate steps to insure its actuation.

The shaft 27 has also journaled upon it av c .ratchet disk 80, see Fig. 6,y immediately below the three-arm cam 7 8. y The ratchet has six teeth' and six flat lands, and is. held againstreverse movement by a locking pawl 81 pivoted at'82 upon a stationary part of the machine head and urged toward the ratchet diskby a tension spring 108,' to be referred to later. The ratchet disk 8O also cooperates with a dog S3, pivotally mounted upon a vertical pin 84projecting from a boss on the slide 43. The dog has a rearwardly extend. arm S5, as shown in Fig. 5, which is acted upon by a Vcompression spring located in a boss 86 projecting outwardly from a statio-naryV but adjustable arm 87 secured'to the trame of the machine head. The dog 83 is thus at all times pressed against onev of the lands of the ratchet disk 8O and in the normal operation of the machine slides Vback and forth in Contact with the land asthe slide 43 is reciprocated. When it is' desired to have the dog 83 turn the ratchet 80, itis Vnecessary to impart to the ratchet a slightrotary movenient in a clockwise direction to advance one oi the ratchet teeth into the path of the dog 83. lThe mechanism for effecting this result is under the. control of the Voperator and will now be described. I y Beneath the ratchet disk 8O on the shaft 27 ispivotally mounted a swing piece 100', shownseparately in Fig. 10.y rFhis'is of irregular shape and Vis provided with a boss 16.11 from which projects a downwardly extending stud 102. The piece 100 is swung in a counter clockwise direction by a tension spring 1.03 secured to the stud 102 at its front end and at its rear end to a pin 137 projecting upwardly from a hook link v136, to be presently described. The swing piece 100 is moved in the opposite direction and in opposition to the spring103 by a link 104, pivotally mounted upon theouter end of an arm 130. l

The swine piece 100 has a radial arm or barrel 105 in which is mounted a spring pawl 106 designed to cooperate with the ratchet disk 80 and to rotate the latter in a counter clockwise direction suiiiciently to position one tooth of the ratchet disk in the path of the dog S3 when the swing` piece 100 is rocked. A pin 107 projects upwardly from the hub of the piece 100 and serves as anchorage for the other end of the tension spring 103 which holds the locking pawl 31 against the ratchet. The swing piece 100 also has an upright boss 100 in which is mounted an upwardly yi,elding dog 110 which normally projects below the surface of the swing piece, as shown in F ig. 4, in position to engage a roller 112 mounted upon the arm 56, already described as carrying the raceway shifting link 52. lVhen, therefore, the swing piece 100 is moved into the path of the roller 112, the link 52 is locked in extended position and the raceway held in position to deliver long tacks from the raceway channel 20.

The swing piece 100 is provided with a second upstanding boss 114, in which is mounted a downwardly yielding dog 115 which cooperates with a safety lever 116 pivotally mounted upon avertical stud 117 projecting from a stationary ,part of the trame. The lever 116 is arranged to be swung back and forth by a segment lever 11S pivotally connectedV to the inner end oit the lever 116 and meshing with rack teeth cut in the side of the slide 43, as shown in Fig. 6. The safety lever 116 has a curved downwardly extending flange on its lower surface which stands in the path of the dog 115 while the slide 43 is in its for vard position and while the tack separator is open. It thus acts positively to prevent the swing piece 100 from being moved and the raceway shifted pt when the slide 43 is retracted and the separator closed.

Before proceeding to a oescription of the mechanism for moving the swing piece 100 and the effect of such movement, the bunter gauge mechanism will be first described in order that its correlation "to the raceway shifting mechanism may be apparent. Th

bunter 17 is pivotally mounted in the slide 90, arranged to be moved inwardly and outwardly in inclined ways formed in a stationary arm 91 secured to the frame of the machine head. The arm 91 is extended to :form the thin edge gauge 16 and when the bunter gauge 17 is advanced to the outward limit of its travel it occupies a position in registration with and immediately beneath the gauge 16, as indicated by dotted lines in Fig. 3. The slide 90 is connected at its rear end to a forked link 92, w ich, in turn, is connected to a bell crank lever 93 pivotally mounted upon a stud 04 projecting downwardly from a part of the arm 91, as shown in F ig. 7. The inner end of the bell crank lever is connected through a link 95 to the bell crank lever 63 journaled to swing upon the lower end of the vert-ical pin 57 and being forked to provide spaced bearings upon the pin 57. The outer arm of the bell crank lever 63 carries the upwardly projecting pin 62 to which the other end of the tension spring 61, already mentioned, is connected, so that the bell crank lever 63 is urged at all times to swing in a clockwise direction and to advance the bunter gauge 17 to its forward limit.

The limiting position of the lever 63 and the bunter gauge is determined by a short inwardly projecting arm 64 on the lever 63 which engages the inner face of the yoke -71 lt will be apparent, therefore, that it the latter yoke is moved in a counter clockwise direction, as seen in Fig. 8, the bell crank lever 63 will be moved in a direction to retract the bunter gauge. The proportion of the parts is such that a limited swinging movement of the yoke 7 0-71 moves the bunter edge gauge shifting mechanism sutliciently to cause the latter to travel from one to the other limit of its path.

Tie mechanism by which the swing piece 100 is controlled by the operator will now be described. The arm 130 is fast upon the upper end of a vertical rod 131 journaled at its upper end in a stationary bracket projecting from the rear of the machine head. The arm 130 carries an adjustable stop screw 132 cooperating with a stationary abutment 133 on the frame to limit its movement in a clockwise direction about its axis. At its free end the arm 130 carries a stud 134 to which the link 104 is pivotally connected and to which is also connected the hook link 136 carrying the stud 137, to which the rear end of the spring 103 is connected. it its tree end the hoc-k link 136 is guided between ears 133 projecting outwardly from the body of the yoke 70 71 so that the hooked end of the link is positioned at all times to engage the stud 62 on the bell crank lever 63 which controls the shifting of the bunter gauge. The spring 103 has the double function of holding the hook link .inwardly in operative relation to the stud 62 and or holding the rear end of a slot in the link 104 normally against the stud 102 of the swing piece 100. Under certain circumstances, however, the swing piece 100 can be swung against the tension of the spring 104 so that the end of the slot in the link 104 is carried away from the stud 102.

The vertical rod`131 is journaled at its lower end in bearings in a bracket 140 secured to the column 11 :and provided also with bearings for the lower end of the vertical shaft 27, as shown in Fig. 2. rlhe rod 131 vhas adjustably secured to it above its lower bearing a cross arm 141 connected at one end to atension spring 142, tending at all times to turn the rod 131 in a clockwise direction. kAt its other end, the cross arm is connected through a universal joint to a link 143 which extends forwardly and downwardly'and'is connected at its forward end to a treadle 144. The treadle 144 is'located at the left side of the column and is arranged for vertical Inovef ment whereby the rod 131 may be turned in opposition to the spring 142 tomove the arm 130 outwardly or in a clockwise direction.

Having described the mechanism of the machine herein shown, the manner ofiits operation will now be set forth, and for this Apurpose it will be assumed that the machine is to be employed inall round lasting a Mc- Kay shoe having a thin insole reinforced in theshank and heel part with leather or libreboard. For such work the operator desires to employ long tacks about the toe of the shoe on account of the-*added thickness of the toe stiifener in the upper material and to position the shoe bythe bunter gauge'. Proceeding along theforepart, the operator desires to employ short tacks-and to gauge the work by the thinedge gauge.: VVReaching the shank'part where the reinforcing material 152 is lirst encountered,.the operator desires to employ long tacks on account of the added thickness of the reinforcing material in the sole and to position the shoe by the thin edge gauge. Passing about the lheel seat, the long tacks are still employed but the bunter gauge is again relied upon in positioning the shoe.

i Passing into the shank on the second side of the shoe, the long tacks are maintained but the 'bunter gauge is retracted. Reaching the forepart on the second side ofthe shoe, short tacks are again employed and theshoe'ispositioned from the thin edge gauge. Finally, again reaching the toe, the bunter is brought forward and the lasting operation finished employing long tacks again. p

The parts of the machine are shown in Figs. 1, 2, 3 and 'with the bunter gauge retracted and he raceway positioned to deliver short tacks. The raceway is so positioned because in a subsequent cycle of the machine the three-arm cam 78 has been turned to move the yoke 74 to the inner limit of its travel, swinging the yoke in a counter clockwise direction to the limit of its oscillation and permitting the spring 61 to swing the arm 55 in the same direction, retracting 'the link 52 and moving the raceway channel lfl into registration with the tackpassage 51 of Athe separator. As already made plain, the machine will continue to operate under these conditions so long as the operator does nothing to vary the cycle.l Operationin this manner, therefore, continues while the shoe ris being lasted along one side of the for'epart between the tip line and the line at the ball where the forward edge of the'reinforcing material 152 is encountered.

As already pointed out, the bunter gauge tained inthe position shown in Fig. 9. In

this movement the hook link 136 is moved toward the right vso that it'engages the pin 62 on the bellcrank lever 63 and holds'the latter in the same position as it formerly occupied and as shown in Fig. 5, that isto say, at the limit 'of Vits movement in acounter clockwise direction with the bunter gauge 17 in retracted position.

vThe movement of the arm 130 alsoA rocks the swing piece and the ratchet disk 80 as above, so that -in the ensuing reciprocation ofthe slide 43 vthe ratchet disk isl again carried one-sixth of a revolution forward and the yoke 7.4 is moved tothe outer limit of its horizontal` oscillation, swinging the yoke 70-71 so that the intermediate portion thereof is carried away from the karm 64 on the lever 63. rlhe vlatter,-however, is now prevented from following the movement of the yoke by the actionof the hooklink 136. The swinging movement of the yoke 7 0-7 1 also swings the arm 56 in `a clockwise direction advancing the link 52 and swinging the racewayl to bring the long track channel 20 into operative position. So long as the operator maintains the treadle 144 in depressed position, the cycle of the machine is repeated, long tacks rbeing delivered and the bunter gauge eing held in retracted position.

' lf the operator shouldzdepress the treadle 144 too early in-thecycle of the machine, that is to say, while the slide143 is advanced from its initial position, the flange` of thesafety lever 116 will-preventmovement of the swing piece 100 by standing'in front of the dog 115 which is mounted therein. yUnder these circumstances, depression of the treadle and movement of the arm 130 merely places the spring 103 under additional tension yiand moves the link 104 aspermitted by its slot connection with ,the downwardly extending stud 102. Depression of the treadle, therefore, maintainsthe spring 103 under tension and when the slide 43 is eventually moved to its vinitial position the safety .lever V116 is moved to release the swing piece 100 and its movement then takes place with the results above set forth.

When the operator has completed lasting the shank and reaches the heel-seat portion of the shoe, it is desirable to advance the bunter gauge into operative position but to maintain the machine in condition for delivering long tacks on account of the added thickness of the counter and the reinforcing material in the insole. In order to organize the ma chine for operating in this manner, it is nec.- essary merely to release the treadle 144i, whereupon the link 104 is moved to the inner limit of its travel, lost motionoccurring between the slot in the link and the stud 102. The hook link 136 is also moved toward the left at this time and is thrown outwardly and disengaged from the pin 62 by the cooperation of the inclined surface of its throat with the curved surface of the yoke -71 between the ears 138. The bell crank lever 63 is thus disengaged and is free to be swung in a clockwise direction under the actuation of the tension spring 61. The bell crank lever 93 is thereupon swung by the link 95 in the direction to advance the bunter gauge, the forward movement of the latter being limited by the engagement of the arm 64 on the lever with the inner face of the yoke 'Z0-71. Fig. 11 of the drawings illustrates the machine organized for operating in the manner above explained.

Upon reaching the shank on the second side of the shoe, the operator may again retract the bunter gauge without disturbing the delivery of long tacks by depressing and holding the treadle 144;. This initiates the movement of the ratchet disk 80 as above and causes the power-operated inward movement of the yoke 74, during which the bell crank lever 63 is rocked in a counter clockwise direction by the engagement of the yoke 71 with the arm 644 so that the bunter gauge is withdrawn. As the treadle is maintained depressed, the swing Apiece is held at the limit of its movement in a counter clockwise direction and the dog is positioned to engage the roller 112 on the arm 56. The link 52 is, therefore, locked in extended position and the raceway maintained in position to deliver long tacks from the raceway channel 20.

'Upon leaving the reinforced shank portion of the shoe-and arriving at the forepart on the second side where short tacks are again desired, the operator will release the treadle, whereupon the swing piece 100 is permitted to move and release the roll 112 on the raceway shifting arm 56, so that under the actuation of the spring 61 the raceway is shifted again to the position shown in Fig. 5 of the drawings, wherein the raceway channel 19 for short tacks becomes operative, and since the yoke 7 4 is moved from the position shown in Fig. 11 to that shown in Fig. 5, the yoke 'T0-71 now occupies a position to hold the bunter operating lever 63 in bunter-retracting position.

Finally, in lasting about the toe portion of the shoe, the treadle is again depressed and released, whereupon both the raceway and bunter are shifted and the machine is organized for driving long tacks with the bunter advanced.

It will be apparent that the machine may be employed in lasting in any order or progression desired and that whether moving from heel to shank or from forepart to shank the appropriate position of the raceway and .edge gauge for shank lasting is obtained by depressing and holding the treadle 144. It should be further noted that after shank lasting succeeding forepart lasting the release of the treadle positions the parts for heel-seat lasting, and that after shank lasting succeeding heel-seat lasting the release of the treadle positions the parts for forepartJ lasting. 1n other words, the organization of the machine is so controlled that without special attention on the part of the operator, the machine adapts itself in anticipation of the lasting conditions desired in the part of the shoe about to be presented.

It willbe noted that the spring 59, in addition to its function of maintaining the yoke 54 in Contact with the screw 55 in the raceway shifting mechanism, provides relief in the train of mechanism in case the race-way should become jammed, as by a misplaced tack, when the arm 56 is moved positively b y the yoke YO-71 in shifting the raceway from long to short tack position. Under these circumstances, the spring will yield and permit lost motion to occur between the yoke 54 and the screw upon which it is suspended. lnasmuch as the shifting of the raceway from short to long tack position is effected under the actuation of the spring 61, there is no danger of breakage if the raceway should be jammed against movement in that direction.
