34 Claims. 1
This invention relates primarily to punching mechanisms, although in some aspects it is not thus limited in its applicability, the present application being a division of a copending application for Letters Patent for improvements in Shoe machines, Serial No. 584,763, filed on March 26, 1945, on which Letters Patent No. 2,420,665 were granted on May 20, 1947. The invention is herein illustrated as embodied in mechanism attached to a toe-lasting machine constructed generally as disclosed in United States Letters Patent No. 2,324,509, granted on July 30, 1943, on an application of mine, but modified in some respects as shown in later disclosures of mine including Letters Patent No. 2,391,461, granted on December 25, 1945.
It has been proposed, as disclosed in the lastmentioned Letters Patent, to position shoes in the above-mentioned toe-lasting machine in proper relation to the lasting means by a member engaging the insole of each shoe in an indentation previously formed in the insole in predetermined relation to the edge of the shoe bottom. An object of the present invention is to provide improved mechanism for forming or punching such an indentation, or hole, in the insole, and such punching mechanism is herein shown as attached to the frame of a toe-lasting machine of the abovementioned character and operated by power derived from that machine. Such power is supplied by fluid under pressure, the machine having means for developing and for maintaining such pressure during a cycle of operations, as fully disclosed in the above-mentioned Letters Patent No. 2,324,509.
The insole-punching attachment herein shown includes a punch which is operated to form the required indentation or hole in the insole while the shoe is supported by the hands of the operator, and further includes gage mechanism which is movable laterally of the shoe to position the latter relatively to the punch prior to the operation of the punch. The position of the shoe lengthwise is further determined by a member which serves in response to the presentation of the shoe by the operator to render both the punch and the gage mechanism operative. More particularly, movement of this member closes the electrical circuit of a solenoid which operates a valve to admit fluid obtained from the fluid-pressure system of the lasting machine to fluid-pressure means for operating the gage mechanism, from which fluid-pressure means a restricted passage for the fluid leads to other fluid-pressure means provided for actuating the punch, thus insuring the proper sequence in the operation of the gage mechanism and that of the punch. To cause the parts to return to their starting positions after the punching operation the electrical circuit is broken by the movement of the punchoperating mechanism. For imparting the operative movement to the punch the construction shown comprises a spring-operated hammer which is retracted against the resistance of a spring and is then released to the action of the spring by the fluid-pressure means associated therewith. The hammer is movable in a path substantially at right angles 'to the path of movement of the punch and acts on the punch through an intermediate member which is mounted for swinging movement, the hammer and its spring being parts of a self-contained hammer unit pivotally connected to this swinging member. Various novel features of the invention are to be recognized in the organization thus provided.
The above-mentioned gage mechanism, in the construction herein shown, comprises two pairs of opposite side gages, one pair being displaced lengthwise of the shoe from the other pair and the gages of each pair being connected together for movements toward or from each other independently oi the movements of the other pair. To insure that th shoe will be properly positioned, the difierent pairs of gages are operated respectively by different fluid-operated members which are movable independently of each other by the pressure of fluid thereon. Conveniently, as shown, these members are pistons movable in opposed relation to each other in a chamber common to both of them. It will be evident that with respect to this'ieature, as well as some others, the invention is not limited in utility to insole-punching mechanisms.
The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more par-. ticularly described with reference to the accompanying drawings and thereafter pointed outin the claims.

Further to position the shoe laterally and angularly in proper relation to a punch hereinafter described for punching the hole in the insole, there are provided two pairs of side gages Z2 and 24 includingrespectively arms 26 and 28 arranged to extend lengthwise of the shoe and pivotally mounted on studs 30 on the casting [2. The two gages 22 are arranged to act on the shoe at the opposite. sides of the forepart in the vicinity of. its ball-'"portion, and the two gages 24 are arranged to act thereon at the opposite sides of its toe portion. Each arm 26 carries a stud-32 on; which is pivotally mounted a small :block 34 faced with leather or other appropriate material 36 for contact with the shoe, the block being movable about the stud 32 short distances limitedby its contact with the arm 26 to permit it to adjust itself to the shoe. Each arm 28 has lator provided for storing fluid obtainedsfrorn the.

The toe-'lasting'machine shown in Fig. 1, as
fully disclosed in the previously mentioned Letters Patent; is provided with a plurality of fluidoperated instrumentalities which operate on the shoeinfthe-courseof-a cycle of power operations ofthe-machine. As disclosed particularly in Letters Patent No.-'2-,39 1 ,46l, the shoe is presented tor-the -machine by the operator with the bottom of ithe' forepartoftthev insole in engagement with a plate 2 provided with: a spur 4 whichentersa v small holeon indentation. previously. formed in V the forepart' f theinsole-.toposition. the shoe lengthwise andlaterally in proper relation to the lasting.-instrumentalities, and it .is. clamped against the. plate 2 substantially at the beginningofithe cyclepfaoperations by upward movee mentpi a. fluid-operated. toe rest 6. fiuid.; pr ferably: oil... is. supplied by a ontinuous driven ;pump,(not shown) from a reservoir or sump.8;;to rpressurechamber or manifold (also not-shown) inwhich the fluid is maintained under pressure by the pump during each cycle of Ope a ons To, provide theinsole with the small hole or indentation to receive the spur 4 therev is supported on an: arm I01 fast on the right-hand side of. the frameof the machine the reater portion of," the' insole-punching mechanism embodying features ofj the present invention. This mechani'sm includes a casting I2 on the front end portion 'of'which' are rotatably mounted two 'rolls [4' (Figs. 1,2 and 9) arranged to engage the bottomface of. the forepart of the insole 'in locationsspaced apart-widthwise of the shoe when Operating the-shoe is presented thereto bottom upward by I the'operator. A third roll- I6 is rotatably mounted on'a plate l8 (Figs-6 and 9) secured tothe lower face of the castinglZ. and. is arranged to. engage theinsole in. a location nearer the toe endthereofthan they rolls I4 and substantially midway between the sides of the toe. The three rolls thus; serve. as a shoe rest and facilitate movement of the shoe in a toeward direction after the operator has presented the .-shoe-against them. Such movement: of the shoe is limited by engagement of its, toev-endface'with'an arm 20 which serves as an end gage for theyshoe and fastthereonaa block 38 (Fig. 4) faced with leather 401.: or other? suitable material and provided Withan upwardly extending stem 42 secured to thearm by a nut 44. Integral With the arms 26 are arms 46 (Fig. 9) extending inwardly toward each other and connected together by gear teeth sothat the arms 26 will swing; equal distances inyunison-toward orfrom theshoe. --Sim-ilarly the arms 28' have integral therewith inwardly extending arms idconnected together bygear teeth" so that the arms-28'- 'also willswing-equaldistances inunison toward or-fromtheshoe.

tween the pistons'so thatall-the gases.- are movedwhen the lasting machine is idle there-is provided I an; accumulator 16" more; particularly 5., hereinafter described, which is charged with fluid by the lasting machinerand stores the fluid under pressure for operating the insole-punching mechanism. The fluid is conducted from the accumulator to the cylinder 64 through a pipe 18. Admission of fluid from the accumulator to this pipe is controlled by a valve 80 (Fig. 7) mounted in a chamber 82 at one end of a casting 84 which is part of the accumulator and is supported on the side frame of the lasting machine. The valve 80 is a sleeve valve slidingly mounted on a tube 86 which is divided by a partition 88, one end of the tube communicating with the accumulator and the other end with the pipe 18. When the valve is in its initial position, as shown in Fig. '7, the accumulator is not in communication with the cylinder 64 and the latter is open to exhaust through the pipe 18 and ports 90 in the tube 86, these ports communicating with the chamber 82 from the upper portion of which the fluid is returned to the sump 8 (Fig. 1) through a pipe 92. Movement of the valve 80 toward the left with reference to Fig. '7 opens communication through an annular chamber 94 in the valve betweenthe ports 90 and other ports 96 in the tube 86, thus admitting fluid from the accumulator to the pipe 18. Such movement of the valve is effected through a lever 98 (Figs. '7 and 8) pivotally mounted on a stud I which is supported by a lug I02 extending downwardly into the chamber 82 from a cover plate I04 over the chamber, this lug also supporting a splash shield I06 positioned over the ports 90 and 96. At its lower end the lever is provided with a pin I08 extending into a groove I I0 in the valve. normally in its initial position by a spring I I2 in engagement at one end with a washer I I4 which bears on a lug II6 extending upwardly from the cover plate I04 and in engagement at its other end with a block H8 pivotally mounted on the upper arm of the lever 98 which extends through a slot in the cover plate. A rod I is pivotally mounted on the lug I I6 and extends through the spring and the block H8. The upper end of the lever 98 is connected by a link I22 to the armature I24 of a solenoid I26 supported on the top of the casting 84. Accordingly, when the electrical circuit of the solenoid is closed the lever 98 is operated to move the valve 80 into position to admit fluid from the accumulator to the pipe 18. Such closing of the electrical circuit is effected by the pressure of the toe-end face of the shoe against the previously mentioned arm 20 (Fig. 6) when the shoe is presented by the operator to the insole-punching mechanism. This arm is pivotally mounted on a pin I28 on the casting I2 and is controlled by a spring I30 which is positioned between a lug I32 on the hub portion of the arm and a portion of the casting I2 and tends to swing the arm in a clockwise direction with reference to Fig. 6. Movement of the arm in this direction is limited by its engagement with an edge face I 34 of the casting I2. In this manner the normal position of the arm is determined. Pivotally mounted at I36 on the lower end of the arm is a block I38 which is further controlled as hereinafter described and has adjustably secured to its lower face a plate I40. One edge of this plate is arranged to engage a knob I42 fastened to a switch member I44 which extends into a switch box I46 on the casting I2 and by inward movement against the resistance of a spring (not shown) is arranged to close the electrical circuit of the solenoid. The switch, not shownin detail,
The valve is held is one of a well-known type requiring only a very.
short movement of the switch member I44 to close the circuit. Movement of the arm 20 by the shoe is limited by a screw I48 which is threaded in the lug I32 and is arranged to engage the casting I2. Accordingly the arm is effective not only as a switch-closing member but also as an end gage for the shoe to determine the distance from the end of the toe of the hole punched in the insole.
To form the hole or indentation in the insole there is provided a punch I50 (Figs. 5 and 6) comprising a pin vertically movable in a bore in the casting I2 and having a conically pointed lower end for engagement with the insole. On the upper end of the pin is formed a plunger I52 movable downwardly in another bore in the casting against the resistance of a return spring I54. The plunger I52 is engaged on its upper end by a hardened contact piece I56 carried by a member I58 which is pivotally mounted on a pin I60 on the casting I2. The member I58 is provided with two downwardly extending fingers I62 between which is a pin I64 fast on the casting I2 for limiting movements of the member in opposite directions by engagement with the fingers. As the parts are shown in Fig. 6, the member I58 is held by the spring I54 in the position determined by engagement of the pin with one of the fingers, the punch I50 being retracted above the insole of any shoe presented to the machine. When the punch is operated to punch the hole in the insole its movement is limited by engagement of the pin I64 with the other finger I62 of the member I58, its movement being sufficient to punch the hole only part way through the insole, as illustrated in Fig. 5.
The movement of the member I58 to operate the punch I50 is effected by mechanism which I will now be described. Pivotally connected by a pin I66 to this member is a block I68 to which is rigidly connected a rearwardly extending rod I10, the block and the rod being parts of a, self-contained hammer unit I12. The rod I10 extends through a cylinder I14 which also is a part of the hammer unit and is provided with a roll I16 resting on a flat face I18 formed on a portion of the casting I2. This face accordingly supports the hammer unit against the force of gravity. Surrounding the rod I10 inside of the cylinder I14 is a spring I80. Mounted on the rod i a, washer I82 which is seated against inwardly extending flanges I84 (Fig. 2) of the cylinder I14 and itself provides a seat for one end of the spring. The other end of the spring is engaged by a washer I86 also mounted in the cylinder I14 and confined on the rod I10 by a nut I88. A narrow rearwardly extending portion I90 (Fig.2) of the block I68 lies in a vertical slot in the front end of the cylinder I14 between the flanges I84 to permit relative movements of the block and the cylinder in directions lengthwise of the cylinder while preventing the cylinder from turning relatively to the block. It will be evident that the spring I by its pressure on the washer I82 tends to Fig. 2. Pivotally mounted on a pin I92 (Fig. 6)
on the casting I2 is a lever I94 on the upper end of which is secured a hardened wear plate I96- arranged to engage the edge of a similar plate I98 ascent:
referenceto Fig-. 6' and-to move thepiston 202 to the limit of its inward movement determined-by Operating fluid isadmitted-to the innerend of 5 the cylinder 204 fromthe previously mentioned cylinder fid'throughapassage 2 l 2. By the action of the fluid the piston 2132 is forced. outwardly and swings the-lever l'fl l in a clockwise direction as far as permitted by. engagement of. the-1owerend oflthe lever with that. face of the casting, which is engagedbythe Plunger. 208. In the course of thismovement of the lever. the-plate I 96 bylengagement withthe plate {98 impartsto'the cylinder I'M lengthwisemovement'in a direction away. from the blockltt and thereby compresses the spring I80 through the action of the washer I82 on the spring, this movement of the cylinder being not'of sufficientextent' to cause'the rear-. wardly extending. portion I90 of the block 168 to. 1 be withdrawn from-the slotin the cylinder. Prior to the completion" of the' movement'of the lever I94 the plate 196 slips downwardlypa'sttheedge of'the plate I98, thus releasing thecylinder H4, whereupon the spring 180 impel the cylinder suddenly in the reverse direction until its front end strikes against the block I6 8. By its momentum-the cylinderthus acts as a hammer to swing the member I58 and thereby to impart operative downward-:movement td-theipunch r50 against 40 the resistance of the "spring I 54, themovement of the member litbeing'limited by the-pin l64 as herei'nbefore described. The passage 2I2 connecting the cylinder '64 to'the cy1inder 20'4 is-a're-' stricted passage suchas to retard the flow of the fluid to the cylinder 2M and thereby-to insure that the gages 22- and 24 willproperly position the'shoe before the punch is operated.

The pressure of tlie fiuid' in thiscylinder" then moves-'the pistons 62 in outwardf directionsfl an'd tliereby-swings the-pairs of 'sidegagesQ-fiaiid 26 inwardly to position the shoe between them relatively to the punch I50, as illustrated in Fig. 9. At the same time fluid passes from the cylinder 64 to the cylinder 204 through the restricted passage 2 I 2 for imparting outward movement to the piston 202. The movement of this piston swings the lever I94 to retract the cylinder I14 against the resistance of the spring I80 through engagement of the plate I96 with the plate I98, the cylinder being released to the action of the spring when the plate I96 is moved far enough to disengage it from the plate I98. The spring then operates the cylinder I'I4 as a hammer which by impact on the block I68 swings the member I58 to impart operative movement to the punch I50, the movement of the punch being limited by engagement of the pin I64 with one of the fingers I62. The punch thus forms a hole or indentation in the bottom of the insole without passing entirely through it, as illustrated in Fig. 5. As the punch is thus operated the arm 2I6 of the member I58 acts through the rod 2" to swing the block I38 upwardly and thus to release the switch member I44, thereby breaking the electrical circuit of the solenoid. The valve 80 is then returned by the spring II2 to its initial position, closing the outlet from the accumulator and opening the ports 90 to the chamber 82 to permit exhaust of fluid from the cylinders 64 and 204. The side gages are then returned by the springs 52 and 54, thereby moving the pistons 62 inwardly in the cylinder 64 as far as permitted by their flanges I0, and the piston 202 is returned by the spring 2 I through the lever I94, the hammer unit I12 being swung upwardly by this lever member I58 and to the hammer unit I12. The i return of the member I58 permits the plate I40 to resume its initial relation to the switch member I44 upon return of the gage member 20 by the spring I30 when the operator removes the shoe. The operator then presents the shoe to the lasting machine in position for the spur 4 of that machine to enter the identation formed in the insole and starts the operation ofthat machine. In the course of the operation 01 the lasting machine the accumulator is again fully charged with fluid passing through the pipe 238 to'the chamber 226. The operator will ordinarily present each shoe, after the first one, to the insolepunching mechanism while the lasting machine is operating on a shoe previously operated on by that mechanism, but the charge of fluid maintained in the accumulator permits the use of the insole-punching mechanism at any time.
While the insole-punching mechanism is herein shown asyoperating on a shoe which has already been partially lasted, as is appropriate in view of its attachment to a toe-lasting machine to prepare shoes for immediate presentation to that machine, it will be. understood that such mechanism might be used for punching holes in insoles mounted on lasts prior to the mounting of uppers on the lasts.
