forward side and being inwardly curved at 52 at its rear. This form, as will later more clearly appear, allows the mounting member to freely receive the leg-portion of a high shoe, as the last within the shoe is brought into engagement with the bed-plate. A considerable vertical portion or the member 42 is unbroken, giving the full strength of lthe metal to resist the pressure applied in the heeling operation; -but near its lower end it has a lateral slot 54 receiving an upward laterally extended projection 56 from a bedplate 58. From front to rear or the mounting member extends a groove or arcuate depression 60, in which nts the complementallylcurved surface 62 of the plate, these surfaces taking the thrust of the applied pressure of the machine, yet allowing the plate to tilt laterally. ,',Ilierprojection 56 holds the plate against displacement, having in it an arcuate slot 64 receiving the cylindrical end 66 of a screw 66 threaded horizontally produces no increase Vin the dimensions of the `member 42 from front to rear, and but slightly enlarges laterally this portion of the support. At the bottom of the bed-plate 58 is a plane surface 70 arranged for contact with the end of a cone of a last L within the shoe S. `From this surface depends a pin 72 to enter the last-opening 1 and position said work transversely of the plate. About the periphery of the bedplate is an inclined surface diverging upwardly andeutwardly from the surface 'l0 and forming a projection 74, this serving to hold the top of the jacked'shoe away from the upper extremity ofV the last-cone and thus prevent the top from being pinched between the last and the bed-plate.

In using the work-support of this invention, the operator, with thejack drawn forward from above the die-block and heel-holder, applies the lasted shoe S to the pin 72 upon the plate 58, the projection '74 holding the shoe-top away from the contactingsurfaces of the plate and lastcone, and the laterally reduced plate-mounting 42 receiving the upper extremity of the top within its contracted portion, without throwing any strain upon the work as the last is settled in place upon the pin. The jack-post is then swung into the nailing position appearing in Figs. 1 and 2 of the drawing, and the shoe is correctly located by its engagement with the band-'clamp 17 with reference to the heel H, which has been inserted in the holder 14, and to the nail-passages in the die-block l2. Movement of the mounting slide 30 along the ways 40 of the member 42 enables the operator to carry the jack-post back against its stop after the rearward travel of the work, bed-plate and mounting means has been stopped by the band-clamp. Shifting the slide longitudinally of the ways 26 provides for the proper introduction of the work into the bandclarnp. The turning of the last about the pin 72 to correctly present the lasted shoe to the heel tends to throw the top of the last-cone out of registra- This condition the operator may correct by rotating the projectiony 28 of the slide 30 in the ways 26 to the necessary extent, or until no part of the contact-surface of the cone liesoutside the plate. Crushing and mutilation of the last'is thus avoided. The oscillation of the bed-plate 58 about the pivot 66 on the mounting member, upon the application of clamping pressure by the heeling machine, comi pensates for the lack of parallelism between the end of the last-cone and the general plane of `since the mounting elements of the smaller bedplates are interchangeable in the ways 26 of the post. The bed-plates of this invention may quickly be substituted for one another, together with their mounting members 38 and 42, by release of the single latch 34 manipulated directly from the operators position. This facilitates the employment of a plate of the size best suited for .the particular lasts in the slices being operated upon.
