12 Claims.

This invention relates to fastening-inserting machines, and is herein illustrated as applied to a machine of the type disclosed in Letters Patent No. 1,815,295, granted on July 21, 1931 upon an application of George Goddu, for driving staples to fasten shoe uppers in lasted position. It is to be understood, however, that the invention is not limited to machines of that particular type nor to machines for fastening shoe uppers.

Machines constructed as shown in the abovementioned Letters Patent comprise in their organization means for driving staples from a guiding nozzle through the shoe upper materials and into an insole to fasten the upper to the insole, and a deflector for engaging the legs of each staple to curve different portions of the legs successively in the driving operation before the different respective portions enter the shoe and thus to cause them to follow curved paths such as to anchor them effectively in the insole without necessarily penetrating entirely through the latter. Since the upper materials are sometimes thicker at one portion of a shoe than at other portions, for example at the shank portion near the heel seat where the counter may be interposed between the upper leather and the lining, it is desirable to vary the degree or radius of curvature of the legs of the staples in operating on such different portions of the shoe in order that the staple legs will be effectively anchored in the insole. The machine disclosed in the above-mentioned Letters Patent was accordingly provided with means for varying the position of the deflector relatively to the staple-guiding nozzle to effect such a variation in the curvature of the staple legs, such means comprising an eccentric controlling the deflector and an adjusting member movable by the operator to turn the eccentric quickly to different predetermined positions corresponding to the desired curvatures of the staple legs in different portions of the same shoe. In View, moreover, of the fact that the uppers of different kinds of shoes also sometimes vary considerably in thickness, the machine above referred to was further provided with means whereby an additional turning movement of the eccentric could be effected to vary the radius of the curvature imparted to the staple legsin operating on different shoes without substantially altering the ratio between the different curvatures predetermined as above described for different portions of the same shoe.

The present invention provides improved means for effecting the above-mentioned variations in the curvature of the staple legs with greater facility than heretofore, and more particularly improved means for quickly effecting an adjustment for this purpose in accordance with differences in the thickness of the upper mate'- rials at different portions of the same shoe or an adjustment in accordance with differences in the thickness of the uppers of different shoes. As illustrated the different respective adjustments are effected through members that are movable I at any time for the purpose in view in response to force applied thereto by the hand of the operator, so that no appreciable loss of time is involved in varying as desired the curvature of the staple legs. The construction shown comprises a member mounted for turning movement to vary the position of the deflector, a device that is' frictionally clamped to this member for turning it and is movable in opposite directions to different predetermined positions corresponding to the desired curvatures of the staple legsin different portions of the same shoe, and means that is carried by the movable device and is itself mov-' able to turn the above-mentioned member additionally an indeterminate distance against the resistance of the friction with which the member is clamped to vary the curvature of the staple legs in accordance with differences in the thickness of the uppers of different shoes.

The novel features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawing and pointed out in the claims.

In the drawing,

Fig. 1 is a view in right-hand side elevation of a portion of the head of a machine in which the invention is embodied, with parts broken away;

Fig. 2 is a perspective view, with parts broken away, showing the means for varying the curvature of the staple legs detached from other portions of the machine; and

Fig. 3 is a sectional view illustrating howthe staple is driven and curved to anchor it in the insole.

In view of the disclosure in the above-mentioned Letters Patent of details of the construc- 4 tion of the machine to which the invention is herein shown as applied, only such parts as it tom as the operator presents the shoe in positions determined by a sole rest 12 and a side gage 14. In time relation to the pulling of the upper in each location a staple is driven from a guiding nozzle 16 by a driver 18 to fasten the upper to the insole. As the staple is driven its legs are engaged by a deflector 20 the lower end of which is positioned opposite the end of the nozzle 16, the deflector acting to curve different portions of the legs successively before the different respective portions enter the shoe to cause the legs to follow curved paths such as to anchor them eifectively in the insole without entirely penetrating through the insole, as illustrated at s in Fig. 3. The driver 18, the deflector 20 and other parts associated therewith are carried by a slide 22 mounted on a guiding member 24'for forward movement in a downwardly inclined path. In predetermined time relation to each upper-pulling operation the slide 22 is moved forwardly to carry the nozzle 16 and other parts associated therewith inwardly over the shoe bottom to lay the margin of the upper over the insole, whereupon the staple is driven and the slide 22 is then retracted to its starting position.

As also disclosed in the previously-mentioned Letters Patent, the deflector 20 is mounted on a pivot pin 26 for turning movement to vary the distance between the portion thereof that engages the legs of the stapleand the points where the legs emerge from the end of the staple nozzle 16 and thus to vary the degree or radius of curvature imparted to the legs in the driving operation, the position of the deflector being determined by an eccentric 28 formed on a shaft 30 which is carried by the slide 22 and is mounted for turning movement to adjust the eccentric. By reference to Fig. 3 it will be seen that the eccentric 28 bears on a boss 32 formed on the deflector 20 and thus limits movement of the deflector about the axis of the pin 26 in the direction to increase the distance between its lower end and the outlet end of the nozzle 16 and accordingly to increase the radius of curvature of the staple legs; It will be understood that the boss 32 is forced against the eccentric by reason of the pressure applied to the deflector in the staple-driving operation, and there is suflicient friction tending to prevent the deflector from turning about its axis to cause it to maintain any position determined by the eccentric.

The shaft 30 in the construction herein shown is, in part, supported by a bracket 34 which is fastened by screws 35 to the slide 22. For turning the shaft and the eccentric 28 to vary the position of the deflector 20 in such manner as to alter the curvature of the staple legs in operating upon different portions of the same shoe, there is provided a device or member 36 having a split bearing portion 38 friotionally clamped to the shaft 30 by a screw 40. Formed as a part of the member 36 is a handle 42 for use in turning the memberand the shaft 30. For the purpose described the member 36 is thus movable in opposite directions between definitely predetermined positions corresponding to the desired curvatures of the staple legs in operating on difierent portions of the shoe. For determining such positions of the member 36 it carries a spring-pressed latch 44 arranged to enter a notch 46 provided in the edge of an arc-shaped portion 48 of the bracket 34 and also arranged to enter a notch 50 provided in a member 52 which is adjustable to different positions along a guideway 54 provided in the arc-shaped portion 48 and is heldf in adjusted position by a set screw 56. When the latch 44 is in the notch 46 the eccentric 28 is set to cause the legs of the staple to receive a curvature of comparatively short radius, as desired in operating, for example, on the forepart of a shoe, and when the latch is in the notch 50 the eccentric is set to cause the legs to receive a curvature of longer radius, as may be desired in operating along the shank portion of the shoe bottom near the heel seat, the radius of this curvature being determined by adjustment of the member 52 along theguideway 54. The latch 44 and the notches 46 and 50 are so formed that the latch will slip out of either notch in response to pressure applied by the operators hand to the handle 42, so that the operator can move the member 36 instantly from one predetermined position or limit of movement to the other at any time.

For additionally varying the position of the deflector 20 to eifect a variation in the curvature of the staple legs in operatingv on different shoes there is provided, in the construction shown, means ior imparting to the shaft 30 turning movement of indeterminate extent against the resistance of the friction with which the shaft is clamped to the member 36. For this purpose there is fixed on the outer end of the shaft 30 a segmental gear member 58 which is engaged by another segmental gear member 60 fast on a short shaft 62 mounted in a bearing in the member 36, thisshort shaft being provided with a hand lever 64 for turning it. It will thus be seen that the mechanism for turning the shaft 30 against the resistance of the friction with which the shaft is clamped is carried by the member 36 and is movable with the latter to the different positions determined by the latch 44 and the notches 46 and 50. While the member 36 is in either predetermined position the shaft 30 may be turned by the operator any distance desired merely in response to pressure applied by the operator's hand to the lever 64.

To avoid any danger of injury to the operators hand in the use of the illustrated mechanism the bracket 34, as shown in Fig. l, is so shaped as to extend far enough rearwardly beyond the forward edge of the adjacent portion of the frame to obviate any possibility that the operators fin.- gers may be caught between the bracket and the frame in the reciprocatory movements of the slide 22.
