Definitions

  • the present invention concerns such machines as these for drilling openings in the heel-seats or the heels and heel-seats of shoes to prepare them for the insertion of an attaching screw.
  • the guard is provided with a locking member controlled by the contact of the Work, which locking member holds it against movement until said work has been applied to the guard.
  • a careless operator may present the insole of a shoe at such an angle to the work-engaging end of the guard, with the toe inclined upwardly and inwardly, that the contact of the counter-portion with the locking means will release it, so the boring movement may take place prematurely. Under these conditions, the drill may pass into the heel-seat and heel in the Wrong direction, possibly emerging through the rear of the heel. It is an object of this invention to prevent errors oi this character.
  • This result may be obtained by mounting the locking member for compound movement in diierent directions, a component in one direction freeing the member for action, while that in another direction releases the guard for movement.
  • the locking member may co-operate with different movement-limiting means.
  • I utilize a normally locked lever for locking the guard, which guard is shown as a slide, the lever receiving from the work a movement of translation to free it from its lock and arranged to oscillate upon its fulcrum to release the guard.
  • the guard-slide preferably carries a fulcrum-pin passing through a slot in the locking lever to allow the bodily yield which releases the lever for movement of oscillation, this, in turn, releasing the guard for 1. ⁇
  • Fig. 1 being a vertical, longitudinal section th e-rethrough Fig. 2, a partial similar view, showing the elements in their operating relation;
  • Fig. 4 an enlarged, horizontal, sectional detail through the fulcrum of the locking lever.
  • a driven spindle Ill carrying a drill or other tool I 2 extends through a tube I4 projecting horizontally from a bracket It.
  • a tube I8 Arranged to slide within the tube I4 is a tube I8 having xed at its outer eX- tremity a block 20 for engagement with the work.
  • the operation to be performed consists in drilling through the heel-seat of a shoe into an attached heel, the shoe being held with the rear of the counterportion down.
  • the block may have the general form of the rear of a last, it being adapted to hold the Work applied to its end face 22 with the heel-seat-surface in correct relation to the drill, both as to the location in the insole oi the bore produced and the angl-c of this bore to the insole-surface.
  • the block 28 with its guideetube I8 is held normally out, with the surface 22 outside the point of the drill, by a spring 24 interposed between the block and the bracket I6 and surrounding the tubes H5 and I 3. Its inactive position is determined by a head upon a stop-rod 26 projecting horizontally from the bracket and passing through an opening in a rearward extension 28 of the block.
  • the block With the block forced out by the spring 24, it 55 serves as a guard, protecting the operator and the work from accidental contact with the rotating drill. With a shoe S and its heel H applied to the block and pressed in against the resistance of the spring, the block furnishes a guide for the work, initially positioning it in the correct relation and maintaining this throughout the operation.
  • a locking member 3D This, as in the apparatus previously referred to, is in the form of a lever fulcrumed to oscillate about a horizontal pin 32 fixed in a depending portion 33 of the block.
  • the lever is normally so held by a spring 34 acting upon a plunger 35 that its inner end lies opposite a face 36 upon the bracket I6. If the operator presses against the end 22 of the block prior to the placing of the Shoe over it, the extremity of the locking lever strikes the face 3B before the point of the drill is exposed because of the movement of the block.
  • a rotatable tool for operating upon the heelportions of shoes, a rotatable tool, a work-engaging member movable along the tool, and a locking member arranged to hold the work-engaging member against movement by the work and movable to release the work-engaging member, said locking member being normally secured against movement in a direction to effect such release while movable in another direction to free it for such release.
  • a drill In a drilling machine for shoes, a drill, a guard for the drill movable under the influence of work held in the hands of the operator, and a locking member arranged to hold the guard normally against movement by the work and to release the guard by a combined movement of oscillation and translation relatively to said guard.
  • a drill In a. drilling machine for shoes, a drill, a guard for the drill movable under the influence of work held in the hands of the operator, and a normally locked member for retaining the guard against movement, said member being mounted for compound movement, a component of which in one direction acts to release the member for action and in another direction to release the guard for movement.
  • a drill In a drilling machine for shoes, a drill, a guard for the drill movable under the influence of work held in the hands of the operator, a movable locking member for the guard, means for limiting the movement of the member in one direction to prevent unlocking the guard while permitting limited movement of the member in another direction, and means preventing the unlocking movement until the limited movement in such other direction has occurred.
  • a drill In a drilling machine for shoes, a drill, a guard for the drill movable under the influence of the work, and a. normally locked leve-r for locking the guard, said lever having imparted to it by the work a movement of translation to free it from its lock and arranged to be oscillated upon its fulcrum to free the guard.
  • a drill In a drilling machine for shoes, a drill, a support associated therewith, a slide movable upon f the support along the drill, and a locking member pivoted upon the slide to move between positions in which it may respectively engage and clear the support and further being shiftable to bring diierent points into engagement with its pivot, contact with a portion of the slide normally preventing the assumption of such supportclearing position.
  • a drill In a drilling machine for shoes, a drill, a support associated therewith, a slide movable upon the support along the drill and carrying a fulcrum-pin, and a locking lever for the slide fulcrumed upon the pin for oscillation and for bodily movement along said pin under the influence of the work.
  • a drill In a drilling machine for shoes, a drill, a. support associated therewith, a slide movable upon the support along the drill and carrying a fulcrum-pin, a locking lever for the slide having a. longitudinal slot through which the pin passes, and a yieldable member acting to hold one extremity of the slot in normal contact with the pin and the lever locked. by contact with the slide against oscillation about the pin, movement upon the pin under the influence of the work releasing the lever for oscillation to free the slide.
  • a drill In a drilling machine for shoes, a drill, a movable guard for the drill having an end face with which the Work may contact to eiect the movement, and a locking lever for the guard fulcrumed upon said guard for both bodily and oscillatory movements and with its end projecting beyond the end face, the lever locking the guard by engagement with a relatively xed member and being locked by engagement with the guard, movement of the Work against the proijecting end of the lever shifting it bodily to release it from its lock and further movement of the work over the end face of the guard oscillating the lever to free the guard for the drilling operation.
