Definitions

  • This invention relates to a boot nailing machine.
  • h'lachines of this type were fitted hitherto either with a horn or with a holder for an iron last.
  • the conveying of the boot was effected by an awl stuck into the sole.
  • the conveying can however not be effected in this manner when the machine is fitted with a last support as at the conveying of the comparatively heavy last support the awl breaks, being adapted merely to convey he unloaded boot.
  • the driving device for the horn is in machines of this type not capable of executing such a long stroke that it would be possible to substitute without any modification a last holder for thehorn.
  • the machines with last holder of known type are not adapted for the nailing by means of a horn as the feeding is in such machines generally tted with the fabric presser arranged for one side only so that when a horn would be substituted for the last holder' the boot would tilt on said horn. rlhere does consequently not exist a practical boot nailing machine which is capable of working perfectly either with a horn or with a last holder. 1
  • the boot nailing machine according to my invention is designed to fill this gap.
  • the machine according to thev invention can be used either with a last holder or with a horn.
  • the feeder of the machine has a two-sided foot, known per se, and the carrier which supports either .a last holder or al horn is adapted to executea long stroke.
  • An arbor is preferably arranged so that it bears on the carrier for the last holder or the horn and engages with the hollow shaft of the last holder or the horn, rod being hingedly connected with said arbor, by the raising of which rod in La mann 4r similar to a crowbar, the last holder vor the horn is temporarily raised, the carrier being simultaneously secured in its position in order to press during the working of the machine the work against the nose of the fastener inserting mechanism.
  • the machine accordingto the invention is specially adapted to be used in bootanakers workshops in which alternately boots are made and repairs are erzecuted. .he horn is best adapted for Inaking new boots.
  • This horn can however be used with advantage for repairing boots the welt of which is still undamaged and smooth and further for repairs of top boots as it is difficult to accommodate the top on the last holder below the last.
  • the nailing on lasts or the use of the last holder' is necessary however when the bad state of the welt does .not permit of a perfect feeding of the boot on the horn,
  • the feed foot is preferably controlled by a bush oscillatable around a bolt with the aid of a cam and adapted to be displaced on said Y bolt in axial direction by means of a capstan
  • the feed foot of the machine executes at first a straight lined downward movement and then a straight lined movement in lateral direction.
  • the feed foot is vertically moved downward by means of a ram acting upon a sliding surface of thefeed foot, whereupon it is moved in lateral ⁇ direction by meansl of an oscillatable .arm with which the feed foot is vconnected by a bolt engaging with a longitudinal slot.
  • the feed foot may be guided, with this object in view, by means of horizontal cross slots on the ram which is vertically guided.
  • a lever arm which effects the lateral movements of the feed foot may 6be fitted with a precisely worked curved face, which curved face holds the feed foot in its final position without play in contact with the other Iguiding means, for instance the bolt.
  • the hammer and awl which with the object in view of becoming alternately operative, are mounted in an oscillatable guide piece can, according to the invention, be guided at the upper end in the oscillatable frame which essentially is of a height corresponding to the length of hammer and awl, by means ot the tool holder in longitudinal guides of said oscillatable frame and at the lower end by engaging with a lower plate ot said oscillatable frame so that the hammer and awl are consequently, in opposition to the commonly used arrangements,not guided only in two places, but in three places.
  • the double gui-ding in the commonly used machines is effected by the tool holder and the plunger situated directly above the tool.
  • he third guiding is situated when the tool is penetrating into the work, approximately at the centre of the tool, so that even in cases in which the work opposes considerable resistance to the penetration oit the tool a breaking or bending of' the tool need not be feared.
  • This arrangement ensures further a low building height. It is advantageous to arrange the last holder according to the invention in a plane perpendicular to the longitudinal axis of the last and inclined with regard to the shaft as with such arrangement the nails penetrate into the sole obliquely with regard to the edge ot the sole and consequently have a more solid hold in the sole.
  • the shaft which carries the last holder can be bent and directly below the last holder a ball-joint can be arranged adapted to be locked by means of a cap nut in order to permit of varying atl will the angle of inclination of the last holder.

  • This nut 3 is connected by springs 4 with the .trarne of the machine and by a link 5 with the pedal lever G.
  • The. springs 4 press the rod 1 and consequently the last holder l or horn f mounted on said rod normally in upward direction so that the boot mounted on the last holder or on the horn is pressed against the machine head.
  • rlfhe pedal lever G serves for pulling the boot away from the machine head with a long stroke in order to enable the adjusting of the boot or any other manipulations.
  • the last holder CZ or the horn j may be mounted on the rod 1 .
  • the last holder consists of the shaft 7 which is hollow at its lower end and bent so that its upper part is inclined at an angle towards the lower part.
