A machine for lasting heel seat portions of shoes, comprising:
- a shoe support for supporting, bottom uppermost, a shoe comprising an upper positioned on a last and an insole on the last bottom;
- a wiper assembly, comprising a central wiping member, carried by a support therefor, and two wiper plates, each carried by a wiper carrier, said member being fixed against rotation, while said carriers are mounted for pivotal movement, each about an axis which lies within the confines of the central wiping member, the member and plates presenting a substantially continuous leading edge portion whereby lasting marginal portions of the upper of a shoe supported by the shoe support can be wiped over and pressed against corresponding marginal portions of the insole of such shoe;
- and
- fastener-inserting means, associated with the wiper assembly, whereby fasteners can be driven, through a series of apertures formed in the wiping member and wiper plates, adjacent the leading edge portion presented thereby, for securing said wiped-over lasting marginal portions of the upper to the corresponding marginal portions of the insole, two such apertures being disposed side-by-side in the central wiping member, and the fasteners driven through said apertures being the most heelwardly disposed of the fasteners inserted by the fastener-inserting means,
- wherein advancing means is provided whereby the support for the central wiping member and the wiper carriers can be advanced towards the shoe support, cam means also being provided whereby pivotal movement of the wiper carriers can be effected in response to operation of the advancing means, the position to which the central wiping member is advanced as aforesaid determining the location of insertion of the most heelwardly disposed fastener(s), while the amount of pivotal movement of the wiper carriers, and thus of the wiper plates, determines the overall pattern in which the fasteners are inserted, characterized in that the advancing means is operatively connected to the wiper carriers, and each wiper carrier is connected to the support for the central wiping member, for relative sliding movement therebetween, by an arcuate groove-and-projection connection, the center of curvature of which coincides with the axis of said wiper carriers and in that the construction and arrangement of the cam means is such that during a first part of the operation of the advancing means the wiper carriers are advanced towards the shoe support, while in a subsequent part each carrier merely pivots about its axis.
