Apparatus for immersing lasted boots in a liquid bath

Claim 1

An apparatus for immersing lasted footwear, particularly boots in a bath of an immersion liquid, comprising a vertical central shaft; a table rotatable about the shaft; a plurality of rod arrangements supported at the periphery of the table at equally spaced intervals thereabout; a supporting roll and a last carried by each rod arrangement; a circular guide track positioned in a horizontal plane about the shaft and spaced above the rotatable table, said guide track having a hiatus therein; the supporting rolls normally travelling along said guide track; an immersion bath located below the rotatable table and the hiatus in the guide track, the length of the hiatus corresponding in peripheral length with the length of a portion of the guide track located between two adjacent supporting rolls; said lasts one after another being movable downwardly into the bath through the hiatus in the guide track and thereafter upwardly from the bath without interruption of their rotary movement about the central shaft; movement means operable to support each rod arrangement during its downward movement into the bath,and following immersion of the lasted boot in the bath to return the supporting roll onto the guide track; each rod arrangement including a plurality of pivotally interconnected rods defining a polygon; support means on the rotatable table to which each rod arrangement is pivotally mounted for movement in a vertical plane, the mutual position of the last and the rod pivots being such that during the downward and upward movement of the rod arrangement through the hiatus in the guide track the lasted boot is in a position inclined to the perpendicular, and in a vertical position during immersion; a second roll attached to one of the rods of said rod arrangement; and a rotatable disc constituting a part of the movement means against which said second roll bears during the movement of the lasted boot for immersion to prevent undesired torsion and bending strains on said rod arrangement.

Claim 2

An apparatus for immersing lasted footwear, particularly boots in a bath of an immersion liquid, comprising a vertical central shaft; a table rotatable about the shaft; a plurality of rod arrangements supported at the periphery of the table at equally spaced intervals thereabout; a supporting roll and a last carried by each rod arrangement; a circular guide track positioned in a horizontal plane about the shaft and spaced above the rotatable table, said guide track having a hiatus therein; the supporting rolls normally travelling along said guide track; an immersion bath located below the rotatable table and the hiatus in the guide track, the length of the hiatus corresponding in peripheral length with the length of a portion of the guide track located between two adjacent supporting rolls; said lasts one after another being movable downwardly into the bath through the hiatus in the guide track and thereafter upwardly from the bath without interruption of their rotary movement about the central shaft; movement means operable to support each rod arrangement during its downward movement into the bath,and following immersion of the lasted boot in the bath to return the supporting roll onto the guide track; each rod arrangement including a plurality of pivotally interconnected rods defining a polygon; support means on the rotatable table to which each rod arrangement is pivotally mounted for movement in a vertical plane, the mutual position of the last and the rod pivots being such that during the downward and upward movement of the rod arrangement through the hiatus in the guide track the lasted boot is in a position inclined to the perpendicular, and in a vertical position during immersion; a second roll attached to one of the rods of said rod arrangement; and a rotatable disc constituting a part of the movement means against which said second roll bears during the movement of the lasted boot for immersion to prevent undesired torsion and bending strains on said rod arrangement.
