25 Claims.

This invention relates to fastening inserting machines and methods and is herein illustrated as applied to a machine of the type disclosed. in United States Letters Patent No. 1,815,295, granted July 21, 1931, on an application filed in the name of George Goddu, this machine being particularly adapted to secure a shoe upper, after it has been tensioned over a last, in lasted relation to a sole member on the last bottom by means of metallic fastenings, such as wire staples. It is to be understood that in its more general aspects the invention is not limited to use in machines of that particular character nor to the manufacture of shoes.

In the machine of the above mentioned Letters Patent, a staple is formed from a piece of wire and thereafter is inserted through the overlasted marginal portion of the upper into the sole memher without penetrating the entire thickness of the latter. This Condition, which is desirable since the points of the staple legs do not enter the inside of the shoe, is obtained by progressively bending the staple legs during the driving operation to cause the staple legs to follow curved paths in the sole and to curl back toward the face of the sole from which they entered it. The staple legs are bent by a deflector which, in the machine of the above mentioned patent, is located on the side of the sole whence the staple is driven and serves to curve successive portions or the staple legs before they enter the sole.

It is an object of the present invention to im prove upon the construction and operation of machines of the above mentioned type, particularly to insur that each staple is so inserted that its crossbar is firmly embedded in the work (in the present case the marginal portion of the shoe upper) without the danger of the deflector impeding, due to its position, such complete insertion of each staple by th staple driver.

To this end and in accordance with a feature of the invention, the illustrated machine is provided, in addition to shoe upper tensicning means, such as a gripper and wiping means for laying the marginal portion of the upper inwardly over the sole, with upper fastening means including a staple driver and a staple deflector, the arrangement being such that the deflector, prior to the insertion of the staple, is caused to enter the substance of the work and serves to bend the staple legs progressively within the substance of the work and after the staple legs have entered the work. This construction insures that each staple is fully inserted into the work with its crossbar embedded in the work surface, since the driver no longer is prevented by the deflector from moving down to the surface of the Work to drive the staple bar home. At the same time this construction in no way disturbs the accuracy of cooperation between the driver and the deflector essential for inserting each staple in a predetermined path in the work.

More specifically, the driver and the deflector are carried by a common supporting member into a position from which they are operated in predetermined directions and in time relation to each other and the operation of both is efiected by a common member which, in the illustrated example, is a lever having connections to additional levers adapted to operate the deflector and the driver. This insures uniformity of operation and accuracy of timing.

In accordance with another feature of the invention, the staple deflector comprises two awllike prongs which enter the work prior to the driving of the staple at a location in which the prongs can guide and deflect the staple legs after the latter have entered the work, the deflector thus, by reason of its positive engagement with the work, effectively holding the work against the operating thrust of the driver. Moreover, since the deflector in entering the work penetrates through the tensioned marginal portion of the upper and enters the sole, the deflector serves the additional purpose of positively holding the tensioned marginal portion of the upper under stress in lasted relation to the sole member before the staple is inserted to secure the upper in lasted position.

Thus, in another aspect, the invention finds expression in a novel method of making shoes, particularly lasting shoes according to which the marginal portion of the upper, after it has been tensioned and laid over the margin of the sole member is immediately secured in lasted position by the deflector which is inserted through it and into the sole. As a result, the benefit of the lasting operation is not even partly lost due to any possible slip back of the marginal portion of the upper after the opening of the lasting gripper and prior to the driving of a staple.

These and other features of the invention are described in detail in the following specification in connection with the accompanying drawings and are pointed out in the appended claims.

In the drawings,

Fig. 4 is a detail view, in left hand elevation, of part of the structure shown in Fig. 1; and

Fig. 5 is a right hand side elevation of mechanism for adjusting the staple deflector.

The illustrated machine in its organization is, except for the construction of portions of the staple driving mechanism and the construction and operation of the staple deflector mechanism,

similar to the machine disclosed in the aforementioned Letters Patent. Accordingly, only such features of the general organization as it is necessary to refer to for an understanding of the invention will be described herein in detail.

It is the purpose .of the illustrated machine to tension a shoe upper A (Fig. 4) over a last B carrying a sole member C (e. g. an insole) on its bottom, to lay the marginal portion of the tensioned upper over and against the plane bottom face of the sole member and to secure the over-- laid marginal portion of the upper in lasted relation to the sole memberby staples D. To this end, the machine is provided with agripper il (Figs. 1 and 4) adapted to pull the upper heightwise of the last and inwardly over the sole ber, and upper fastening mechanism, including a staple driver and a staple deflector, adapted to lay the marginal portion of the tensioned upper inwardly over the sole member and to secure that marginal portion in lasted position. The construction of the gripper mechanism is the same as that of the corresponding mechanism disclosed in or referred to in the above mentioned patent.

To assist the operator in positioning the work piece. that is the last B provided with the sole member C and carrying the shoe upper A, in pro er relation to the operating instrumentalities of the machine, there are provided an edge gage 12,-adjustable height-wise as well as forwardly and rearwardly in the machine, and a similarly adjustable bottom rest I4.

The upper fastening mechanism, including means for forming staples above the line of drive and for transferring them into alinement with the staple driver, is for the most part movable bodily toward and from the work piece in directions inclined to the bottom face of the sole member 0 and the movement toward the work piece is utilized to lay the marginal portion of the upper inwardly over the insole into position to be fastened. Secured to the head of the machine is a supportint member it (Fig. 1) provided with a forwardly and downwardly inclined guideway for a slide 1 3, this slide having mounted thereon the staple transferring, driving and deflecting mechanisms and a portion of the staple forming mechanism. For moving the slide it along its guideway toward and from the Work piece, the slide carries a cam roll 2&3 engaging a cam groove in a cam disk (not shown) mounted on a cam shaft (not shown) of the machine.

The staple is formed from a piece of wire (which is the front end portion of a wire strand) after this piece of wire has been fed into the staple forming mechanism by wire feeding mechanism (not shown), and severed from the wire strand by wire severing mechanism (not shown). The wire severing, staple forming and staple transferring mechanisms with which the present machine is provided are the same as the corresponding mechanisms of the machine disclosed in the above mentioned patent. These mechanisms in part are mounted on a bracket 22 (Figs. 1 and 4) integral with the front portion of the supporting member i6 and in part are mounted on a bracket 255 secured to the lower front end portion of the slide is by screws 2 The wire is advanced by the wire feeding mecha n through a flexible conduit 23 (Fig. 4) to a wire nozzle comprising blocks secured by a screw 32 on an upwardly extending part of the bracket 2s. The wire is fed through an outside staple former (not shown) supported on the brac- 22 on which is also provided a severing knife (not shown). After the wire has been fed through the outside staple former, the slide is caused to move downwardly and forwardly in the machine toward the shoe presented to the machine vith the result that the front end portion of the wire strand is severed. An inside staple former (not shown) mounted on the bracket 25 engages, a result or" the forward movement of the slide iii. the severed piece of wire and pushes it into the outside former to form a staple. Thereafter, the staple transferring mechanism becomes active to move the formed staple into staple driving position. The staple is moved by a transferring member 34 (Fig. 1) which is mounted for movement heightwise of the machine in the slide I3 and which is actuated by a cam operated bar 36. The staple when moved into driving position is tilted by the transferring member as and lowered into a throat which, in construction and function, is like the throat or nozzle of the machine of the above mentioned patent. The throat comprises plates 38 (Fig. 4) secured in opposed relation by screws All! to plates 42 which are fastened together side by side by screw M. The plates 42 are provided at their upper ends with flanges ad which are fastened by screws 43 to the bracket fol on the slide id. The plates are shaped to extend inwardly under the lower edges of the plates 42 and to provide a guideway for a staple driver, to be described, which is T-shaped in cross section. The flanges 55 are provided with up turned portions 5% through which are threaded screws 52, the screws abutting against the bracket 24 and being held in place by locknuts 5d.

The staple driving mechanism comprises a driver 56 (Figs. 1 and 4), already mentioned, which is reciprccated in the guideway formed by the plates 3%} by mechanism to be described. The driver 55 extends into and is movable with relation to a casing 58 (Fig. 1) that contains a driver clamping mechanism and a part of the driver actuating mechanism. The casing 58 is secured by screw bolts iii) to a forward extension 82 of the slide iii, the casing 58 and driver thus participating in the movements of the slide la. The lower end of the casing 58 is provided with a rearward extension 6 engaging a notch provided in the plates 33 and 2 to give additional support to the casing 53. Moreover, the extension has parallel flanges 68 engaging the outsides of the plates 52, The driver 56 extends into a substantially rectangular block 58 which has a sliding fit in the casing '58 and is provided with a bore shaped to accommodate the driver. The block 88 is recessed at its forward end to admit a clamping screw ill which serves to secure the driver 5% to the block 33. The block 68 is also provided with a spherical recess forming a socket in which is received a ball 12 bored diametrically so that the driver can be extended through it and having heightwise extending grooves at opposite sides thereof which are engaged by the bifurcated lower end of a small arm l4 extending through an aperture into the casing 58 and being adjustably secured to a driver operating lever it. The driver 55 thus is fvlcrumed on the arm i l. The driver operating lever is is rotatably mounted on a shaft l8 (Figs. 1 and 2) extending through the forward extension 62 of the slide it and secured against rotation. More specifically, the driver operating lever is mounted on a sleeve fill on the shaft is. The sleeve has a flange 82 abutting the slide extension 22 and carrying locking pins B l engaging holes in the extension 62 to hold the sleeve 8% against rotation and to permit the tightening of a locknut 85 on the shaft '18 which holds the sleeve 85 nd thus the lever 76 in place. On the opposite side of the slide extension 62 the shaft is has a flange 88 carrying locking pins 93 engaging holes in the slide extension 62, thus to immobilize the shaft 12.

To rock the driver operating lever it about the shaft '58, thereby to reciprocate the driver 56, there is provided an operating member in the form of a bell crank lever 92 fulcrumed on a shaft 9 mounted in the slide it. The bell crank lever 52 has a forwardly extending arm carrying a cam roll at which engages a cam track 38 provided in the driver operating lever EB. Downward movement of the cam roll at in the cam track 98 causes a swinging movement or" the lever 16 in a counterclockwise direction as viewed in Fig. l, as a result of which the driver lit is retracted. On-the other hand, upward movement of the cam roll $5 causes a rotation of the lever E6 in a clockwise direction, as a result of which the driver 58 is moved toward the shoe to insert a staple therein. The cam track 98 is so shaped that at the beinning of the upward movement of the roll 95 therein there is a short dwell in the movement of the lever it, for a purpose to be described. The bell crank lever 92 is spring operated to impart to the driver 55 its driving stroke. To this end there is mounted on the hub portion Hit! of the bell crank lever 92 a torsion spring I02 one end of which engages a lug lo l on a downwardly extending arm. i536 of the bell crank lever 92 and the other end of which engages a portion of the slide it. As in the machine of the above mentioned patent the slide it, after having moved downwardly forwardly and after the driver has been operated, is retracted with the driver in its lowermost position. During the retraction the downwardly extending arm Est of the bell crank lever is caused to become locked. To this end the arm Hill is provided with a latch plate H38 which is engaged by a latch Mil pivotally secured on a cam operated: lever H2 rotatably mounted on the machine frame, the latch i l i! being biased by a spring l M which tends to swing the latch H9 about its pivot into latching position. After the latch i it has engaged the latch plate I 08 and when the slide is again advanced downwardly toward the shoe bottom, the bell crank lever 92, due to its latching engagement with the lever H2, is rotated in a clockwise direction (Fig. 1), thereby loading the spring I82. After the slide l8 has arrived in its forward operative position a trip screw lie, secured in a lug of the slide It, has been moved into the immediate vicinity of an upwardly extending arm H8 of the latch HG. However; the latch HE! is not tripped to free the bell crank lever 92 by the screw Ht pushing against the arm N3 of the latch Mil but rather the lever l l2 which carries the latch H0 is operated by its cam (not shown) to cause the arm 1 E8 to abut the screw H6, thereby tripping the latch lit and releasing the bell crank lever 92 to the force of its spring we, The reason for this arrangement is to time the operation of the driver to occur somewhat after the slide l8 has arrived in its operative position to enable the staple forming and transferring mechanisms to form the staple and transfer it into driving position. Rotating the bell crank lever 92 in a clockwise direction, as viewed in Fig. 1, thereby leading the spring M32, as above described, results in a downward movement of the cam roll 95 in the cam track 98 in the cam lever it so that the driver as is withdrawn. Tripping the latch H6 causes a quick upward movement of the cam roll lit as a result of which the driver as is propelled downward to drive the staple into the work with the car of the staple parallel to the sole edge.

To cause the staple, when being driven, to follow a curved path in the work so that the staple curls back toward the surface of the sole member C whence it was driven, without penetrating the entire thickness of the sole member, the stapie legs are progressively bent or deflected during the driving operation. To this end there is provided a deflector lZE (Figs. 1-4) comprising a bifurcated awl-like member which is arranged to enter the work, that is to say to pierce the overlasted marginal portion of the upper and to penetrate part way into'the sole member 0, as illustrated in Fig. 4 of the drawings. The deflector lfiil is caused to enter the work at a point I opposite the outlet end of the throat where the staple emerges when being driven by the driver 56. The two prongs l2! of the deflector lZii have grooves, as illustrated best in Fig. 3, which are curved and which are engaged by the staple legs after the latter have entered the work. The grooves serve to curve or bend the staple legs laterally of the crossbar of the staple so as to make the staple curl away from the edge of the sole member C and back toward the surface of the work whence the staple entered (see Fig. 4). The deflector 522i is mounted to move heightwise of the machine into and out of engagement with the work in a direction substantially normal to the work surface, whereas the driver 55 moves in a direction inclined at an acute angle toward and from the work surface, the driver when on its operative stroke moving inwardly of the machine and outwardly of the bottom of the shoe toward the adjacent edge or" the sole member. Moreover, the deflector E29, as will be described, also is mounted to move with the slide it.

The deflector I2!) is mounted in the machine as follows: The upper part of the deflector is blockshaped and has an upwardly extending stem i2 3 (Fig. 3) which fits into an axially extending bore provided a plunger 26 to which it is secured by 228 so that deflector Hit and plunger 925 may move as a unit heightwise of the ma-- chine. The plunger 626 is movable in a bore E353 provided in a block-shaped deflector guiding member E32 which is secured on a rockshaft its a set screw 38. The guiding member E32 is located between two downwardly extending spaced lugs 538 (Fig. 2) on the above mentioned bracket 2 3, the shaft I35 being rotatably mounted both lugs 938. A rocking movement of the shaft 53:1 thus causes the guiding member 522 to move with relation to the lugs fist, thereby changing the position of the prongs lZZ of the deflector I25, with the result that the curvature of the staple is changed. To this end, the shaft its has an enlarged portion its (Figs. 2 and 3) integral with which'is, an upwardly extending bifurcated member M2. The member 52 engagesan eccentric portion M l or a rockshaft M the left hand end of which (Fig. 2) is arranged in a suitable bearing in the right hand lug 133. The right hand. end (Fig, 2) of the rockshaft M5 is rotatable in a bracket l lo (Figs. 2 and 5) secured to the black t 2% and supporting adjusting mechanism by means of which the shaft 5% may be rocked. this in turn rocking the shaft 535, with the results described. Secured to the shaft 5 .53 is a handle 5 which serves to rock the shaft and carries a spring pressed locking plunger I52 arranged to engage notched stops [E i adjustably mounted on a segment Q55 which is part of the bracket 568. Thus the range of adjusting movement of the handle may be shifted or varied, the handle 55 being held in adjusted position by the stops 554. To make possible furtr adjustment of the deflector 28 in the extr positions of adjustment of the handle the latter is provided with a side bracket in which is mounted a stubshait I55, Splined. to the stub shaft ltd is an auxiliary handle 562 by which the shaft W3 may be rotated. The shaft 35% carries gear segment $54 which meshes with a gear segment I65 on the shaft hi6. By rotation of the auxiliary andle H32, additional movement may thus be imparted to the shaft l hi so that an additional adjustment or the deflector 829 may be effected.

To move the deflector 2d heightwise of the machine and in a direction substantially at right angles to the bottom face of the sole member C into and out of engagement with. the work, the followin mechanism is provided. The guiding member i32 (Fig. 3) is reduced or slabbed off at its upper portion, thereby opening the bore 138 at opposite sides, to permit movement of a cross pin 58 carried by the upper portion of the plunger i2-5. The cross pin 953 extends beyond the opposite sides at the upper portion of the guiding member i32 into slots Eli) provided in the tines of the bifurcated end of an arm H2 secured on a shaft il i which is rotatable in lugs i'lt provided on the bracket 24. To rotate the shaft I'M, the left hand end of it (Fig. 2) has secured to it a forwardly and upwardly extending arm lit which is pivotally connected to the bifurcated end of an arm iSll (Fig. 4) fulcrumed on the left hand portion (Fig. 2) of the shaft IS. A spring 182 (Fig. 4) connecting the arm 89 with a portion of the slide it tends to pull up the :35, thereby elevating the deflector 126. To depress the arm its for the purpose of lowering the deflector into the work, there is provided a deflector operating lever I84 fulcrumed on the left hand portion of the shaft 18. The lever is; is provided with a cam track iBS (Fig. 1) which is engaged by a cam roll 583 carried by the forwardly extending arm of the bell crank lever 93 which, as above described, also serves to actuate the driver 5%, The cam track W6 is so designed that, upon upward movement of the cam roll 5% therein, the deflector operating lever 3 3 is immediately rotated in a counterclockwise direction, as viewed in Fig. 1, this for the purpose of lowering the deflector $28 into the work. To this end, there is provided a latch connection between the lever ltd an the arm E88, the connection comprising a latch plate 193 (Figs. 1 and i) secured to the arm Hill and a. latch 92 in the shape of a bell crank lever pivotally secured to the lever The downwardly extending arm of the latch 492 is arranged to engage the latch plate Nil so that, upon movement of the lever 8 in a counterclockwise direction, the arm I30 is depressed to operate the deflector. For the purpose of breaking this latch connection after the deflector has entered the work and has served to curve the staple legs the rearwardly extendarm of the latch l2 is in engagement with a swivel block carried on a rod 696 and secured in place by nuts and locknuts i923. The rod E connects the latch N32 with a trip arm pivotally secured to the bell crank lever 92 and provided with a tail portion 292 adapted to be engaged by an extension 284 of the cam roll its near the upper end of the upward travel of the latter. To bring about latching engagement of the latch it?! with the latch plate I90, there is coiled about the hub of the latch Hi2 a torsion spring one end of which bears against a pin on the downwardly extending arm of the latch and the other end of which engages a portion of the deflector operating lever fla l. As already mentioned, on upward movement of the cam roll 533 in the cam track E85, the deflector is lowered to pierce through the overlasted narginal portion of the upper A and to enter the sole member C. Just before the completion of the upward movement of the roll 38, it strikes against. the tail portion of the trip arm 29E] thereby lifting the arm and, through the agency of he rod i95, moving the latch 552 out of engagement with the latch plate 99 so that the spring i 52, which has become tensioned as a result of the downward movement of the arm I88, now free to pull the arm 5% up against a stop d3 carried by the slide extension 52. When Sui: the torsion spring E92, which actuates the bell crank lever is loaded upon downward and forward movement of the slide it, the roll 588 is moved downwardly in the cam track E86 and, as soon as it has moved out of engagement with the tail portion 262 of the trip arm Ed t, the torsion spring 2&5 is free to rotate the latch 592 back into latching engagement with the latch plate Hill. The purpose of this arrangement is to insure that the deflector ifit enters the work immediately after the laying of the marginal portion of the upper on the sole member, accomplished by the downward and forward movement of the slide 18 and before the driver 56 is caused to drive the staple into the work. On the other hand, this arrangement insures that the deflector i2!) is immediately withdrawn out of engagement with the work as soon as the staple is driven home and before the slide :8 is again retracted.

In the operation of the machine, the operator presents a work piece, comprising a last B with an upper A thereon and a sole member C, for example insole, on the bottom face of the last, bottom up, to the machine in a position deter mined by the edge gage i2 and bottom rest l4 and inserts the marginal portion of the upper in the open gripper Hi. When the 'rnachine is initially at rest the slide 8 is in its retracted rearward position and the downwardly extending arm i of the bell crank lever 52 is engaged by the latch Mil with the bell crank lever so positioned that two cam rolls E35 and E88 carried by it are in their elevated positions. Consequently, the latch connection 25. 522 between the defiector operating l ver 58 i and the arm 18B is broken and the deflector :29 is up, the driver 51": still being in its lowermost position. After the initiation of a cycle of operations, the gripper IE3 is closed upon the upper and is caused to pull the upper heightwise of the last and to draw the marginal portion of the upper inwardly over the sole member, the gripper then holding the upper stressed until it is released at a later stage in the cycle.

A length of wire having been fed into the staple forming mechanism, the slide it is caused to move forward and downward toward the shoe bottom. This movement of the slide i3 is utilized to perform various operations. fhe throat comprising the plates 38 is carried inwardly over the edge of the shoe bottom, thereby engaging the ten sioned marginal portion of the upper and laying it fiat against the plane bottom face of the sole member in lasted relation thereto. Moreover, the length of wire which has been fed into the staple forming mechanism is severed from the wire strand by the knife to which it is presented by the slide is. The inside former, carried by the slide, then pushes this length of wire into the stationary outside former to form a staple which thereafter is moved by the staple transferring member into driving position in the throat. Finally, the bell crank lever which is carried by the slide :3 and the downwardly extending arm 466 of which is held by the latch iiil, is rotated in a clockwise direction, as viewed in Fig. 1, with the result that the spring W2 is loaded and the cam rolls S5 and 88 are lowered, thereby withdrawing or cocking the driver 56 and permitting the spring 285, as a result of the movement of the cam roll I38 away from the trip arm to move the latch I92 into engagement with the latch plate I95 to establish driving connection between the deflector operating lever ltd and the arm Hill. When the slide it has arrived at the end of its forward and downward travel, the cam rolls $5 and Q88 are located substantially at the lower ends of their respective cam tracks 98 and I86 and the trip screw H5 is now in the immediate vicinity of the arm N8 of the latch iiil. Counterclockwise rotation (as seen in Fig. l) of the cam operated lever H2 then trips the latch HB, thereby releasing the bell crank lever 92 to the force of its loaded spring H32 which rotates the bell crank lever with great speed and force in a counterclockwise direction (Fig. 1). Consequently, the cam rolls 95 and 588 are elevated in their respective cam tracks 98 and I85.

Considering the elevation of the cam rolls 9% and E88 separately and beginning with the action of the cam roll E88, it will be remembered that the cam track H85 in the deflector operating lever I84 is of such shape that the lever I84 is immediately rotated in a counterclockwise direction causing, through the agency of the established connection between the latch E92 and the latch plate 598, a downward movement of the arm 1855. This results in a downward movement of the arms I18 and H2 and of the deflector 928 which is caused to pierce through the overlasted marginal portion of the upper, preferably while it is still held tensioned by the gripper l0, and to enter the sole member as illustrated in Fig. 4. Thus the full tension imparted to the upper is maintained by the deflector having impaled the marginal portion of the upper.

Considering now the action of the cam roll at, it will be remembered that the cam track 98 is designed to permit at first a short dwell in the clockwise movement of the driver o erating lever l6 resu ti g from the u ward movement of the cam roll 9 this to enable the staple transferring member to move the formed st p e to dri ing position in the t roat and the deflector I29 to move into the staple deflecting position inside the work. lhe driver'ilt is then quickly moved down to drive the staple out of the throat into the work, the staple legs, after having entered the work, engaging the curved deflecting grooves provided in the prongs 522 of the deflector and being curled away from the edge of the sole member and upward toward the side of the work from which the staple entered it, without penetrating the entire thickness of the sole member.

It should be noted also that, as a result of the actual penetration of the deflector into the work, the work is effectively held by the deflector against the thrust of the staple driver when on its staple inserting stroke, thus essentially relieving the operator frornthe task of holding the work in proper position and against the work displacing force of the driver.

The staple having been completely. inserted with its crossbar embedded in the work surface, the deflector is immediately withdrawn, as described, while the driver remains down on the work, thus barring any possibility of the deflector interfering with the proper location of the driven staple in the Work upon its withdrawal from the work. As previously explained, the cam roll 288 on its upward travel finally engages the tail portion 262 of the trip arm Zilfi swinging this arm up and thus moving the latch I92 out of engagement with the latch plate 5%, thereby enabling the spring 92 to pull the arm ass up against the stop screw 2% and to withdraw the deflector from the work. The retraction of the slide is into its elevated rear position completes the cycle.

The holes made by the deflector 52% through the overlasted marginal portion of the upper and in the sole member are not objectionable since they are covered by the out-sole after the latter has become attached to the shoe bottom. In fact, -should it be desired to attach the outsole to the shoe bottom by cement, the holes made by the deflector are of considerable benefit since they permit the outsole attaching cement to penetrate through the overlasted marginal portion of the upper into the insole, thereby affording a cement bond of increased strength.

Having thus described my invention, what I claim as new and desire to secure by Letters Patentered the work and to bend the fastening progressively in the driving operation to cause the fastening to become anchored in the work without penetrating the entire thickness thereof.
