Definitions

  • This invention relates to fastening-inserting machines and is herein illustrated as applied to a machine of the type disclosed in Letters Patent of the United States 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 of the type shown in the above-mentioned Letters Patent comprise in their organization a driver 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 difier-ent 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.
  • such machines are provided with means for varying the position of the deflector to vary the degree or radius of curvature of the legs of the staples in operating upon such different portions of the shoe in order that the staple legs will be effectively anchored in the insole, this 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 shoe.
  • Shoes of that kind are usually lasted with staples in the shank and with cement at the forepart, and accordingly, it is desirable that the legs of the staples applied along the sides of the iorepart be driven only partially into the work so that they project somewhat from the upper to facilitate the removal of the staples after the cement has set, while in lasting the shank portion of the shoe where the staples serve as permanent fastening means, the legs of the staples are, of course, driven fully into the work.
  • One object of the invention accordingly, is to provide in a machine of the type herein shown, means for quickly adjusting the machine to drive the staples either fully or partially into the work.
  • the invention in one important aspect provides means controlled by the deflectoradjusting member for varying the limit of driving movement of the driver.
  • the fastening-inserting means is moved inwardly over the bottom of the shoe in each cycle of the machine into upper-fastening position by a forwardly movable slide on which there is a camoperated lever for imparting operative movement to the driver after the slide has completed its forward movement.
  • this lever is mounted for swinging movement on an eccentric sleeve to which there may be imparted in each cycle of the machine in response to the forward movement of the slide a turning movement to cause the lever to be swung in a direction to retract the driver and thus to determine a limit of movement thereof toward the deflector short of its normal limit.
  • a latch For turning the sleeve there is provided a latch connected to the sleeve and held by a spring in position to cooperate with a fixed stop in the machine.
  • the above-mentioned adjusting member for varying the curvature of the staple legs carries a roll which, when it engages a lip on the latch, swings the latch into a position in which it will not engage the stop in the forward movement of the slide.
  • the mechanism for varying the limit of driving movement of the driver may be rendered operative or inoperative at will by movement of the adjusting member, the lip on the latch being preferably so shaped that the latch is released to the action of the spring for engagement with the fixed stop only when the adjusting member has been moved into position to cause the staple legs to be curved on a comparatively short radius, as in operating at the forepart of a shoe.
  • 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;
  • Fig. 2 is a view on an enlarged scale of a portion of the structure shown in Fig. 1, showing the mechanism for varying the limit of driving movementof the driver with the parts in inoperative positions;
  • Fig. 3 is a view similar to Fig. 2 but showing the parts for varying the limit of driving movement of the driver in operative positions;
  • Fig. 4 is a top plan view of the mechanism shown in Fig. 3;
  • Fig. 5 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;
  • Fig. 6 is a sectional view illustrating the driving of a staple only part way in the work to facilitate its subsequent removal.
  • a machine of this type is provided with a gripper Ill (Fig. l) which pulls the upper materials over the last and insole successively in different locations along the edge of the shoe bottom as the operator presents the shoe in positions determined by asole rest l2 and a side gage l4.
  • a staple is driven from a guiding nozzle l6 by a driver I8 (Figs. 2 and 3) to fasten the upper to the insole.
  • a deflector 20 the lower end of which is positioned opposite to the end of the nozzle IS, 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 effectively in the insole without entirely penetrating through the insole.
  • the driver l8, the deflector 20 and other parts associated therewith are carried by a slide 22 I mounted on a guiding member 24 for forward movement in a downwardly inclined path.
  • the slide 22 is moved forwardly to carry the nozzle l6 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.
  • the driver I8 is secured to a driver slide 26 which is movable in a guideway formed in a bracket 28 secured to The driver slide is operated by a lever 30 which is pivoted on a stud 32 on the forward extension of the slide 22, the lever 30 having adjustably secured to its lower end a block 34 which is swiveled in a recess in the driver slide.
  • a cam slot 36 engaged by a roll 38 (Fig. 1) carried by an arm 40 pivotally mounted on the slide 22.
  • the cam slot 36 is so formed that staple driving movement is imparted to the lever 30 by upward movement of the arm 40 and driver retracting movement is imparted to the lever 30 by downward movement of the arm.
  • the deflector 2D is mounted on a pivot pin 42 for turning movement to vary the distance between the portion thereof that engages the legs of the staple and 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 44 (Figs. l, 5 and 6) formed on a shaft 43 which is carried by the slide 22 and is mounted for turning movement to adjust the eccentric.
  • an eccentric 44 Figs. l, 5 and 6
  • the eccentric 44 bears on an arm 48 formed on the deflector 20 and thus limits movement of the deflector about the axis of the pin 42 in a direction to increase the distance between its lower end and the outlet end of the nozzle It and, accordingly, to increase the radius of curvature of the staple legs.
  • the arm 48 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 46 is supported in part by a bracket 50 (Figs. 2, 3 and 5) which is fastened by screws 52 to the slide 22.
  • a device or member 54 having a split bearing portion 58 frictionally clamped to the shaft 46 by a screw 58.
  • a handle 6D for turning the member and the shaft 46.
  • the member 54 is thus movable in opposite directions between definitely predetermined positions corresponding to the desired curvature of the staple legs in operating upon difierent portions of the shoe.
  • the member 54 For determining such positions of the member 54 it carries a spring-pressed latch 62 arranged to enter a notch 64 provided in the edge of an arc-shaped portion 55 of the bracket 50 and also arranged to enter a notch 68 in a mem ber H3 which is adjustable to different positions along a guideway 12 provided in the arc-shaped portion 66 and is held in adjusted position by a set screw 14.
  • the eccentric 44 When the latch 62 is in the notch 64 the eccentric 44 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 68 of the member 10, 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 near the heel seat, the radius of this curvature being determined by adjustment of the member along the guideway !2. In order that the radius of curvature of the staple legs may be Varied as desired in operating, for example, along the shank portion.
  • a second member 76 having a notch 18 formed therein to receive the latch 62, the member 76 being adjustable along the guideway '12 and being held in adjusted position by a screw 80.
  • the latch 52 and the notches 64, 68 and 18 are so formed that the latch will slip out of any one of the. notches in response to pressure applied by the operators hand to the handle 60 so that the operator can move the member 54 instantly from one predetermined position to another at any time.
  • the illustrated machine is further provided with means which is substantially the same as that shown in United States Letters Patent No. 1,938,575, granted on December 12, 1933, upon an application of B. B. Blanchard, for additionally varying the position of the deflector 28 :to efiect a variation in the curvature of the staple legs in operation on different shoes.
  • means which is substantially the same as that shown in United States Letters Patent No. 1,938,575, granted on December 12, 1933, upon an application of B. B. Blanchard, for additionally varying the position of the deflector 28 :to efiect a variation in the curvature of the staple legs in operation on different shoes.
  • the illustrated machine is provided with means controlled by the deflector-adjusting means for varying the limit of movement of the driver toward the deflector.
  • This means comprises a sleeve 82 (Fig. 4) which is rotatably mounted on the stud 32 and has a reduced end portion 84 which forms a bearing for the driver slide operating lever 38, this portion of the sleeve being eccentric to the axis of the stud 32.
  • Formed on the sleeve 82 is a depending arm 88 to which there is pivotally connected by means of a shouldered screw 88 a rearwardly extending latch 98.
  • a downwardly extending lip 82 Formed on the latch is a downwardly extending lip 82 and coiled about the shouldered portion of the screw 88 is a spring 88 which tends to swing the latch 98 downwardly and to hold it whenthe parts are in the positions shown in Fig. 2 with the curved edge '96 of the lip 82 in engagement with a stop 98, illustrated as a roll, carried by the handle 88.
  • sleeve 82 is recessed to receive the projection I84, and coiled about the sleeve is a spring I88 which tends to rotate the sleeve in a clockwise direction (Figs. 2 and 3) and to hold the sleeve with a shoulder I88 thereon in engagement with the projection I84 on the collar I82.
  • the length of the lip 92 is such that the roll 98 is moved out of engagement with the lip when the handle 88 has been swung far enough to the left to move the latch 82 into engagement with the notch 84 and to set the eccentric 44 to cause the legs of the staple to receive a curvature of comparatively short radius.
  • the mechanism for varying the limit of move ment of the driver toward the deflector is operative when the parts are in the positions shown in Fig. 3, this mechanism being rendered inoperative by movement of the handle 68 to the right (Figs. 2 and 3) to move the latch 82 into engagement with either of the notches 78 or 88. It will be evident that as the handle 88 is thus swung to the right the roll 98 by engagement with the curve-d edge 98 of the lip 82 swings the latch 98 against the resistance of the spring 98 into a position in which it will not engage the stop I88 in the forward movement of the slide 22. It will be understood that with the latch 62 in engagem'ent with any one of the notches 84, 88 and I8 the position of the deflector may be additionally varied by movement of the hand lever 8
