My invention relates to improvements in templates v for splitting leather soles which are usually used in repairing shoes.

.An Object of my invention is to provide a template to be used in co-operation with a leather splitting machine, so that, by using the template, the desired thipkness and surface of the sole willbe removed without sl 1tting the sole over its entire area. It is the practice, at the present time, to run a sole .through a splitting machine when "the sole is thicker than re uired for the repair WOI'k at hand, This re uces the thickness of the sole, but at the expense of the Wearing surface, as well as at the edges. In other words, the splittingv machine removes a layer of leather from the soleover its entire area.

Bythe use of my invention, this objection is overcome, and a strip of the 'solefonly is removed, where desired, lea derofthe sole of fullthickness.

g the remain- In the embodiment of my invention illustrated in the accompanying drawing, a template is shown which in use permits the removal of a strip ofleather around, or along the marginal edge of a sole whilejretaining the fullthickness' of the. leather at the center of the sole, or; that, artnormallylocated under the ball of the oot, and, therefore, in

aflposition to receive the most wear. How

ever-,1 do not confine myself to this shape,

: as it will be readily understood that-various .shapes of templates may be used, depending. uponthat portion of the sole desired to be portion to'beretained, in.

removed and that any particular case.

Other objectsv and advantages of my' iii-1 vention will appear in the'specification, ac-

As an article ,of manufacture, a template for shoe soles comprising a sheet of thin transparent material, as celluloid, of a shape and size corresponding to'the shape and size 5 of a leather sole and formed with a centrally disposed opening whose periphery is approxi mately parallel to the outer edge or periphery 1 of said template.
