Definitions

  • This invention relates to lasting machines, and is herein illustrated as embodied in a machine for lasting the toe ends of shoes. It is to be understood, however, that in various novel aspects the invention is not limited to toe-lasting machines, but is applicable, for example, to Inachines for lasting the heel ends.
  • An object of the invention is to provide a machine adapted for convenient use by an operator to perform the lasting operation in a speedy and effective manner with but little effort on the operators part.
  • the construction herein shown comprises a wiper carrier provided with toe-lasting wipers and mounted on swinging supports which are located respectively at diierent distances from the shoe and are movable manually to advance and retract the wipers lengthwise of the shoe, together with a treadle arranged to act through one of the supports to swing the carrier and wipers heightwise of the shoe for upwiping the upper and for later pressing its margin upon the insole.
  • an upwardly extending hand lever mounted to swing about a horizontal axis and connected to one.
  • the invention provides novel means for closing the wipers laterally of the shoe in response to movement of the wiper carrier lengthwise of the shoe. As illustrated, such closing movements of the wipers are effected through levers extending laterally of the shoe and fulcrumed on the wiper carrier, the outer ends of the levers being connected by links to wiper holders on which the wipers are mounted and their inner ends being connected toa normally stationary crank arm, so that swinging movements of the levers in directions to close the wipers result from the move- .ment of the wiper carrier.
  • mechanism is provided for preliminarily adjusting the wipers toward or from each other by swinging the normally stationary crank arm.
  • the invention further provides novel means (c1. viz--nn lengthwise of the shoe, so as to permit a further movement of the wipers in the vdirection to relieve their pressure on the margin of the upper before they are retracted from over the shoe bottom.
  • novel means c1. viz--nn lengthwise of the shoe, so as to permit a further movement of the wipers in the vdirection to relieve their pressure on the margin of the upper before they are retracted from over the shoe bottom.
  • the above-mentioned member on the wiper carrier is not xed thereon, but is yieldable upon lateral engagement of the stop member therewith.
  • themachine herein shown is provided with a toe rest movable by a treadle into shoe-clamping position and with a device for locking it in that position, and in one form illustrated the machine has also a heel rest movable by the operator independently of the toe rest into engagement with the heel end of the shoe.
  • novel means for supporting the heel rest in such manner as tofacilitate its movements into and out of operative position a device arranged to cooperate in a novel manner with such supporting means to lock the heel rest in operative position, and novel means for unlocking the toe rest and the heel rest to permit their return to starting positions.
  • the toe rest and the heel rest may be unlocked by a treadle specially provided for that purpose or, alternatively, by means controlled by that treadle which the operator uses to impart to the wipers their movement heightwise of the shoe.

  • Fig. 11 is a perspective View of the heel rest shown in Fig. 8 and parts associated therewith.
  • the machine comprises a frame 2 on the rear side of which there is secured a bracket 4 having fast thereon a plate 6 provided with three pins 8 arranged to extend through holes in an insole into sockets in the bottom of the forepart of a last to determine the position of the last and shoe relatively to toe-lasting wipers hereinafter described, in accordance with the method disclosed in United States Letters Patent No. 1,674,060, granted on June 19, 1928, upon an application of Arthur F. Pym.
  • the shoe which as illustrated is one of that type in which the margin of the upper in lasted position lies throughout its width in substantially parallel relation to the bottom of the last, is supported under the forepart by a toe rest I0, more particularly hereinafter described, this toeY rest clamping the last against the ends of the pins 8.

  • the bar I2 is further controlled by a bifurcated link 24 pivoted on a rod 26 on the frame, this link being substantially parallel to the lever I4 and of substantially the same length as that arm of the lever to which the lower end of the bar I2 is connected. Accordingly depression of the treadle 26 serves to force the toe rest upwardly into clamping engagement with the shoe after the last and shoe have been mounted by the operator on the pins 8.
  • a plate 28 provided with a plurality of ratchet teeth 30, and arranged to cooperate with these ratchet teeth is a locking pawl 32 pivotally mounted on a rod 34 on the frame and Ahaving integral therewith an arm 36 connected by a link 38 to a crank arm 39 integral with a treadle 4I! mounted to swing about a shaft 42.
  • a spring 44 connected at one end to the crank arm 39 and at its other end to the frame holds the pawl 32 normally in position to cooperate with the ratchet teeth 30.
  • Such return of the toe rest is eiected by a spring 46 connected at one end to the frame and at the other end to the lever I4. It will be understood that by the action of this spring the treadle 20 is swung upwardly. To limit such upward movement of the treadle and determine the normal position of the toe rest thetreadle carries an adjustable stop or buffer 48 arranged to engage a shoulder 50 on the frame.
