Description
lZ~ )S7 This is a division of Canadian patent application Ser.
No. 421,049 filed February 7, 1983 entitled "~RIPPER ASSEMBLY".
The present invention relates to a machine for pulling over and lasting toe portions of shoes.
The term "shoe" where used herein is used generically as indicating articles of outer footwear generally and including such articles in the course of their manufacture.
Machines for pulling over and lasting toe portions of shoes conventionally comprise shoe support means for support-ing, bottom down, a shoe assembly comprising an upper on a last and an insole on the last bottom, a plurality of gripper assemblies arranged in a generally inverted U-formation about the shoe support means, means for effecting relative height-wise movement between the shoe support means and the gripper as9emblies whereby the toe end portion of the upper of a shoe supported by the shoe support means and gripped by the gripper assemblies can be tensioned on its last, and wiper means by which lasting marginal portions of the upper, tensioned as aforesaid, are wiped over and pressed against corresponding marginal portions of the insole of the shoe assembly.
In machines of the aforementioned type, it is often the case that various gripper assemblies are differently constructed according to their position in relation to the shoe support means' further the cost of manufacturing the grippers tends to be greater than if the various assemblies .

were standard one with another. Furthermore, it is frequently the case that, in order to re-set the various gripper assemblies in relation to one another according to the style of shoe to be operated upon, relativel~
S complicated mechanisms are provided and the re-setting operation tends to be time-consuming and tedious. What is more, whereas the individual design of gripper assembly can be dictated to some degree by the general requirements for re setting, where standard gripper assemblies are 1~ provided, the re-setting facilities have also to be standard, and thus accommodate whichever position the gripper assembly is located in.
It is the object of the present invention therefore to provide an improved gripper assembly for use in a shoe toe lasting machine, which gripper assembly is provided with ~ relatively simple setting facilities, but which can neverthe-; less be used in any of the various localities in relation tothe shoe support means of the machine which the gripper assembly is to form part.
The invention therefore provides, in accordance with onè of its several aspects a machine for pulling over and lasting toe portions of shoes comprising shoe support means for supporting, bottom down, a shoe assembly comprising an upper on a last and an insole on the last bottom, a plurality of gripper assemblies arranged in a generally inverted U-formation about the shoe support means, for effecting relative ,, :: ~ . , -f :: :

In addition, more specifically, one adjustment member may be connected to its associated second support plate means via a, further adjustment member adjustment of the position of which is thus effective to vary the relationship between the two adjustment members and thus the relative length~ise positions of the housings.
It will thus be appreciated that firstly by means of the further adjustment member the positions of each of the two most heelwardly i 10 gripper assemblies can be set relative to one another, while, in order, e.g. to accommodate changes between men's and children's sizes, a further relatively coarse adjustment can be made by means of the first-mentioned adjustment member. It will further be appreciated that by both the pin-and slot connection and, in the case of the assemblies other than the two most rearwardly disposed, by the pivotal mounting on the support shaft, orientation of each gripper assembly along an arcuate path can also be achieved.
The mechanism by which the position of the two most heelwardly disposecl gripper assemblies can be adjusted as described above may also be utilized for effecting a rearward pull by said assemblies on an upper, lasting marginal portions of which are gripped thereby, such rearward pull taking place, in the operatiorl of the machine, simultaneously with relative heightwise movement taking place between the shoe support means and the gripper assemblies as a whole.

1 Description of the Preferred Embodiment The machine in accordance with the invention comprises a shoe support means 10 as shown in Figure 1, including a generally U-shaped insole plate by which hot melt adhesive can be applied to the insole of a shoe supported thereby prior to the operation of the machine, as is conventional, and arranged about sa;d plate, ;n a generally inverted U-shaped configuration, is a plurality of (in this case seven) gripper assemblies 12 by which lasting marginal portions of the upper of a shoe supported by the shoe support means 10 can be gripped, whereafter, upon relative heightwise movement beins effective between said gripper assemblies 12 and said shoe support means 10, such upper can be tensioned about its last, also in a conventional manner. The machine also comprises, as is conventional, a heel rest 14, a toe pad 16 and wiper plates 18, by means of which latter the marginal portions of the upper, after being tensioned as aforesaid, can be wiped over and pressed against corresponding marginal portions of the insole, the adhes;ve previously being applied so that said marginal portions are bonded together.
A first gripper assembly in accordance with the invention comprises~a housing 20 as shown in Figure 2 which constitutes a cylinder in which a piston 22 is slidingly accommodate~. A cover plate ` 24 for the cylinder has a first, fixed, jaw 26 formed integral therewith, and pivoted on said jaw 26 is a movable jaw 28, a depending tail portion of which is arranged to be engaged by an end portion of a piston rod 30 carried by the piston 22. A spring 32 acts between the : : ' ~: ~

_ 9 _ 1 fixed and movable jaws 26, 28 urging the tail portion into engagement with the piston rod, and thus urging the gripper jaws to an open condition. Admission of fluid under pressure to the cylinder counters the action of the spring to close the jaw members.
The housing 20 is secured to first support plate ~eans of the gripper assembly, said means comprising an upper plate 34 ~F;gure 3) which is mounted for sliding movelllellt on a lower plate 36 of said means,.the lower plate having a T-shaped projection 3~ which engages in a complementarily shaped slot in the upper plate so as to guide the upper along a rectilinear path in relation to the lGwer plate.
The lower plate 36 is supported by second support plate means of the:assembly in accordance with the invention, said second means compris;ng a block 40. The lower plate 36 has formed, at one end, a depending flange 42 w;th an inturned lip 44, and the support block 40, at a corresponding end thereof, has an arcuate end face 46 and cut-away portion 48 therebeneath, the arrangement being such that, when the assembly is assembled, the cover plate 36 can.pivot relative to the 1. block 40, without risk of jamming, but is nevertheless held in surface : contact with the blocl~ by the interaction of the lip 44 with the cut-away portion 4~. ~
The firsl; and second support plate means are secured together by a ~: . bolt 50 which passes through a slot 52 in the uppèr plate 34 and an :~ aperture 54 in the lower plate 36 and ;s threadedly received in a threaded bore 56 in the block 40. The bolt 50 has a shoulder 58 by which the upper surface of the upper plate 34 is engaged, thus to clamp : : .

: : .
lZ~lOQ57 1 the plates 34, 36 and the block 40 together in adjusted position, a handle 60 being provided on the bolt 50 for easy manual use. The slot 52 serves to allow lengthwise sliding movenlent of the upper plate 34 relative to the lo~/er plate 36, while the aperture 54 enables the first support plate means to be pivoted bodily about the axis of the bolt 50 ;n relation to the block 40.
In this way, the jaw members 26, 28 can be moved in and out towards and away from the shce support means 10, and also are effectively movable lengthwise in relat;on to said support means, while at the same time facilitating arcuate orientation of the jaw members in relation to said support means.
The support block 40 is carried by a support shaft 62 which projects upwardly from and is mounted in a housing 64 secured in a base plate 66 on which all of the gripper assemblies are mounted, and which forms part of the machine frame. A spring 6~ is also accommodated in the housing 64 and acts to urge the support rod 62 and thus the housing 20 upwardly. The support rod 62, which is provided with two flatted ~l portions, also passes through a plate 70 having a slot 72 formed .
therein through which a clamp bolt 74 passes, the bolt being screwed lnto the base plate 66. The slot, which has its center of curvature coincident wil:h the axis of the shaft 62, enables relative movement to take place between the plate 70 and the base plate about said axis, where by the orientation of the support block 40, and thus of the housing 20 and the gripper jaws 26, 2~ can be adjusted. A manually .

- 12~00S7 1 plate 70 in adjusted position. The adjustment about the axis of the shaft 62 is to be regarded as a coarse setting for the gripper assembly, a finer setting then being provided by release of the clamp bolt 50, as described above. The clamp bolts 50, 74 and associated parts constitutes respectively first and second clamp means of the gripper assembly.
It will be seen (from Figure 2) that the axis of the shaft 62 is substantially beneath the piston rod 30, though slightly offset from the jaws 26, 28. The plates 34, 36, on the other hand, are clamped I0 together at a position spaced from said axis. The lip 44 and cut-away portion 48 thus serve to prevent any distortion forces being applied to the bolt 50 arising from the resistance of the gripper jaws (holding the shoe upper) to a downward draft on the assembly for upper-tensioning purposes.
lS A second gripper assembly in accordance with the invention (not shown) is generally similar to the first gripper assembly described above, differing only in that the first support place means comprises a single support block replacing the upper and lower plates 34, 36.
Furthermore, this replacement block has no lip portion, and thus said one end surface of the support block 40 is square-cut and is not cut away.
For urging the gripper assemblies downwardly in relation to the shoe support means 10 whereby to tension an upper gripped by the gripper assemblies as aforesaid, a bar 77, secured by circlips on the ~,5 shaft 62 (thereby enabling the shaft to be rotated relative to the bar) `~

has one end of a Bowden cable 78 connected thereto9 by which a down-drafting force can be applied to its associated gripper jaws, in a manner described in detail in our Canadian Patent No. 1,130,062. For effecting 5 a so-called "discretionary pull" by each gripper assembly 12, furthermore, by which the operator can adjust the position of the tensioned upper on its last, as described in said patent, handles 79 (Figure 1~ are provided,- one associated with each gripper assembly.
In the machine in accordance with the invention, each gripper assembly, other than the two most heel-wardly disposed gripper assemblies, arranged one at either side of the shoe support means 10, can be - constituted eith r by a first gripper assembly or a second gripper assembly as referred to above, while the two mosi heelwardly disposed assemblies 12 (Figure 4) are constituted by third gripper assemblies in accordance with the inventionO In the case of each of these gripper assemblies, the upper plate 34 of the first support plate means is connected, by means of the clamp bolt 50 and slot 52, to a support plate 40', constituting the second support plate means. The first support plate means is thus able to pivot about the axis of the bolt 50 and also to slide in-and-out towards and away from the shoe support means 10, when the first clamp means thereof is released. The support plate 40' is provided on its underside with a slideway 80 by which the plate is mounted on a block 82 fixedly carried at the upper end of the support sha~t 62. The shaft 62 is carried in the housing 64 and urged upwardly by means of a spring 68, as in the case of th~ first : "

In this case, however, there is no facilitv for varying such orientation The longitudinal center line of each block 82, and thus the slide path of each support plate 40', is inclined at an angle of ab~ut 17 to the longitudinal center line of the machine. For effecting adjustment movement of each support plate 40', and thus of each of the two most heelwardly disposed gripper assemblies, along the slide path, the support plate 40' of the left hand gripper assembly as shown in Figure 4 has a block 84 secured to the under-side thereof, said block being connected by a pin 86 to an adjustment plate 88 wilich is mounted on a pivot pin 90 secured in the base plate 66. The right hand gripper assembly also has associated therewith an adjustment plate 88 pivotal about a pivot pin 90, the plate 88 being connected by means of a pin 86 accommodated in an oversize hole in the support plate 40'. Each pin has a knurled retaining nut 87. The adjustment plates 88 are interconnect~d by a linkage 92 such that clock-wise movement of the left hand plate about its pivot 90 causes simultaneous counter-clockwise movement of the right hand plate and vice versa. In this way, the housings 20 of the two most heelwardly disposed gripper assemblies 12 are caused to move simultaneously along their slide pdths .
For adjusting the two gripper assemblies relative to one another, the block 84 of the left hand assembly is secured to the underside of .

The upper end of the pin 86 projects beyond the block 84 and a slot 96 is provided therefor in the support plate.
For effecting movement of said gripper assemblies along their slide paths, the left hand adjustment plate 88 carry a handle 98 associated with which is a depending pin 100, which can be received in a selected one of a row of co-operating apertures 102 formed in a lever - lO 104 also pi~otal about the pivot pin 90 of the left hand assembly. The handle 100 can be slid by hand heightwise of the adjustment plate 88 in order to release the pin 100 from a selected aperture 102, whereafter the adjustment plate can be pivoted using said handle to bring the pin into alignment with another selected aperture. Instead of such an arrangement, an infinitely variable adjustment, e.g. by a conventional clamp together with a pin-and-slot connection, could be used.
Pivotally connected to a lug of the lever 104 is piston rod 106 of ( ~ a piston-and-cylinder arrangement 108 carried by a bracket 110 secured to the base plate 66. h'hen the machine in accordance with the invention is in its rest condition, fluid (e.g. air) under pressure urges the piston rod 106 to its extended condition, and thus the two most heelwardly disposed gripper assemblies are urged toewardly.
Supplementing the arrangement 10~ in this regard, furthermore, is a spring 112 acting between the adjustment plate of the right hand assembly and the base plate 66.

1 Description of the Preferred Embodiment The machine in accordance with the invention comprises a shoe support means 10 as shown in Figure 1, including a generally U-shaped insole plate by which hot melt adhesive can be applied to the insole of a shoe supported thereby prior to the operation of the machine, as is conventional, and arranged about sa;d plate, ;n a generally inverted U-shaped configuration, is a plurality of (in this case seven) gripper assemblies 12 by which lasting marginal portions of the upper of a shoe supported by the shoe support means 10 can be gripped, whereafter, upon relative heightwise movement beins effective between said gripper assemblies 12 and said shoe support means 10, such upper can be tensioned about its last, also in a conventional manner. The machine also comprises, as is conventional, a heel rest 14, a toe pad 16 and wiper plates 18, by means of which latter the marginal portions of the upper, after being tensioned as aforesaid, can be wiped over and pressed against corresponding marginal portions of the insole, the adhes;ve previously being applied so that said marginal portions are bonded together.
A first gripper assembly in accordance with the invention comprises~a housing 20 as shown in Figure 2 which constitutes a cylinder in which a piston 22 is slidingly accommodate~. A cover plate ` 24 for the cylinder has a first, fixed, jaw 26 formed integral therewith, and pivoted on said jaw 26 is a movable jaw 28, a depending tail portion of which is arranged to be engaged by an end portion of a piston rod 30 carried by the piston 22. A spring 32 acts between the : : ' ~: ~

_ 9 _ 1 fixed and movable jaws 26, 28 urging the tail portion into engagement with the piston rod, and thus urging the gripper jaws to an open condition. Admission of fluid under pressure to the cylinder counters the action of the spring to close the jaw members.
The housing 20 is secured to first support plate ~eans of the gripper assembly, said means comprising an upper plate 34 ~F;gure 3) which is mounted for sliding movelllellt on a lower plate 36 of said means,.the lower plate having a T-shaped projection 3~ which engages in a complementarily shaped slot in the upper plate so as to guide the upper along a rectilinear path in relation to the lGwer plate.
The lower plate 36 is supported by second support plate means of the:assembly in accordance with the invention, said second means compris;ng a block 40. The lower plate 36 has formed, at one end, a depending flange 42 w;th an inturned lip 44, and the support block 40, at a corresponding end thereof, has an arcuate end face 46 and cut-away portion 48 therebeneath, the arrangement being such that, when the assembly is assembled, the cover plate 36 can.pivot relative to the 1. block 40, without risk of jamming, but is nevertheless held in surface : contact with the blocl~ by the interaction of the lip 44 with the cut-away portion 4~. ~
The firsl; and second support plate means are secured together by a ~: . bolt 50 which passes through a slot 52 in the uppèr plate 34 and an :~ aperture 54 in the lower plate 36 and ;s threadedly received in a threaded bore 56 in the block 40. The bolt 50 has a shoulder 58 by which the upper surface of the upper plate 34 is engaged, thus to clamp : : .

lZ~lOQ57 1 the plates 34, 36 and the block 40 together in adjusted position, a handle 60 being provided on the bolt 50 for easy manual use. The slot 52 serves to allow lengthwise sliding movenlent of the upper plate 34 relative to the lo~/er plate 36, while the aperture 54 enables the first support plate means to be pivoted bodily about the axis of the bolt 50 ;n relation to the block 40.
In this way, the jaw members 26, 28 can be moved in and out towards and away from the shce support means 10, and also are effectively movable lengthwise in relat;on to said support means, while at the same time facilitating arcuate orientation of the jaw members in relation to said support means.
The support block 40 is carried by a support shaft 62 which projects upwardly from and is mounted in a housing 64 secured in a base plate 66 on which all of the gripper assemblies are mounted, and which forms part of the machine frame. A spring 6~ is also accommodated in the housing 64 and acts to urge the support rod 62 and thus the housing 20 upwardly. The support rod 62, which is provided with two flatted ~l portions, also passes through a plate 70 having a slot 72 formed .
therein through which a clamp bolt 74 passes, the bolt being screwed lnto the base plate 66. The slot, which has its center of curvature coincident wil:h the axis of the shaft 62, enables relative movement to take place between the plate 70 and the base plate about said axis, where by the orientation of the support block 40, and thus of the housing 20 and the gripper jaws 26, 2~ can be adjusted. A manually .

- 12~00S7 1 plate 70 in adjusted position. The adjustment about the axis of the shaft 62 is to be regarded as a coarse setting for the gripper assembly, a finer setting then being provided by release of the clamp bolt 50, as described above. The clamp bolts 50, 74 and associated parts constitutes respectively first and second clamp means of the gripper assembly.
It will be seen (from Figure 2) that the axis of the shaft 62 is substantially beneath the piston rod 30, though slightly offset from the jaws 26, 28. The plates 34, 36, on the other hand, are clamped I0 together at a position spaced from said axis. The lip 44 and cut-away portion 48 thus serve to prevent any distortion forces being applied to the bolt 50 arising from the resistance of the gripper jaws (holding the shoe upper) to a downward draft on the assembly for upper-tensioning purposes.
lS A second gripper assembly in accordance with the invention (not shown) is generally similar to the first gripper assembly described above, differing only in that the first support place means comprises a single support block replacing the upper and lower plates 34, 36.
Furthermore, this replacement block has no lip portion, and thus said one end surface of the support block 40 is square-cut and is not cut away.
For urging the gripper assemblies downwardly in relation to the shoe support means 10 whereby to tension an upper gripped by the gripper assemblies as aforesaid, a bar 77, secured by circlips on the ~,5 shaft 62 (thereby enabling the shaft to be rotated relative to the bar) `~

has one end of a Bowden cable 78 connected thereto9 by which a down-drafting force can be applied to its associated gripper jaws, in a manner described in detail in our Canadian Patent No. 1,130,062. For effecting 5 a so-called "discretionary pull" by each gripper assembly 12, furthermore, by which the operator can adjust the position of the tensioned upper on its last, as described in said patent, handles 79 (Figure 1~ are provided,- one associated with each gripper assembly.
In the machine in accordance with the invention, each gripper assembly, other than the two most heel-wardly disposed gripper assemblies, arranged one at either side of the shoe support means 10, can be - constituted eith r by a first gripper assembly or a second gripper assembly as referred to above, while the two mosi heelwardly disposed assemblies 12 (Figure 4) are constituted by third gripper assemblies in accordance with the inventionO In the case of each of these gripper assemblies, the upper plate 34 of the first support plate means is connected, by means of the clamp bolt 50 and slot 52, to a support plate 40', constituting the second support plate means. The first support plate means is thus able to pivot about the axis of the bolt 50 and also to slide in-and-out towards and away from the shoe support means 10, when the first clamp means thereof is released. The support plate 40' is provided on its underside with a slideway 80 by which the plate is mounted on a block 82 fixedly carried at the upper end of the support sha~t 62. The shaft 62 is carried in the housing 64 and urged upwardly by means of a spring 68, as in the case of th~ first : "

In this case, however, there is no facilitv for varying such orientation The longitudinal center line of each block 82, and thus the slide path of each support plate 40', is inclined at an angle of ab~ut 17 to the longitudinal center line of the machine. For effecting adjustment movement of each support plate 40', and thus of each of the two most heelwardly disposed gripper assemblies, along the slide path, the support plate 40' of the left hand gripper assembly as shown in Figure 4 has a block 84 secured to the under-side thereof, said block being connected by a pin 86 to an adjustment plate 88 wilich is mounted on a pivot pin 90 secured in the base plate 66. The right hand gripper assembly also has associated therewith an adjustment plate 88 pivotal about a pivot pin 90, the plate 88 being connected by means of a pin 86 accommodated in an oversize hole in the support plate 40'. Each pin has a knurled retaining nut 87. The adjustment plates 88 are interconnect~d by a linkage 92 such that clock-wise movement of the left hand plate about its pivot 90 causes simultaneous counter-clockwise movement of the right hand plate and vice versa. In this way, the housings 20 of the two most heelwardly disposed gripper assemblies 12 are caused to move simultaneously along their slide pdths .
For adjusting the two gripper assemblies relative to one another, the block 84 of the left hand assembly is secured to the underside of .

lZ~ S7 1 the support plate 40' by means of a pin 94 screwed into the support plate 40' and accommodated in a slot in the block ~4, release of the pin enabling the support plate 40' to move along its slideway relative to the block 84. The upper end of the pin 86 projects beyond the block 84 and a slot 96 is provided therefor in the support plate.
For effecting movement of said gripper assemblies along their slide paths, the left hand adjustment plate 88 carry a handle 98 associated with which is a depending pin 100, which can be received in a selected one of a row of co-operating apertures 102 formed in a lever - lO 104 also pi~otal about the pivot pin 90 of the left hand assembly. The handle 100 can be slid by hand heightwise of the adjustment plate 88 in order to release the pin 100 from a selected aperture 102, whereafter the adjustment plate can be pivoted using said handle to bring the pin into alignment with another selected aperture. Instead of such an arrangement, an infinitely variable adjustment, e.g. by a conventional clamp together with a pin-and-slot connection, could be used.
Pivotally connected to a lug of the lever 104 is piston rod 106 of ( ~ a piston-and-cylinder arrangement 108 carried by a bracket 110 secured to the base plate 66. h'hen the machine in accordance with the invention is in its rest condition, fluid (e.g. air) under pressure urges the piston rod 106 to its extended condition, and thus the two most heelwardly disposed gripper assemblies are urged toewardly.
Supplementing the arrangement 10~ in this regard, furthermore, is a spring 112 acting between the adjustment plate of the right hand assembly and the base plate 66.

3~ 0 5 7 1 In the operation of the machine, admission of fluid under pressure to the opposite end of the arrangement lO~ is effective to cause said gripper assemblies.to move heelwardly, thereby applying a heelwardly directed pull to the upper gripped thereby. For limiting such heelward 5 movement, either the stroke of the arrangement 108 may be fixed or the pressure of fluid may be set to a given value (in which latter case the amount of movement will be determined by the stretchability of the upper material).
It will thus be apparent that, in using the machine in accordance with the invention, the two most heelwardly disposed gripper assemblies can be positioned along a path inclined at about 17 to the longitudinal center line of the machine, and can thereafter be drawn heelwardly along said direction, the two assemblies operating simultaneously with one another and a single adjustment arrangement and a single power source being required for effecting both adjustment of their position and the application thereby of a heelward pull.
