SHOE-LAST.
Specication of Letters Patent.
Patented Dec. 15, 1914.
Application filed May 9, 1914. Serial N0. 837,427.
To all whom t may concern n Be it known thatl, EvEnETT H. UN' a, a citizen of the United States, re ling at -ynrI the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Improvement in Shoe-Lasts,
of which the following is a specification.
My invention relates to lasts designed to be used for making shoes having a peculiarform of inner sole provided with ay hump or boss intended to support a weakened er fallen or broken arch of the lfoot of the wearer. To make such a shoe it is necessary to use a last having a corresponding depression or cavity in the bottom thereof, and it has been the special object of my invention to make a last the sole-forming cavity of which may be varied or modified without permanently changing the last, so that a person Whose foot needs corrective treatment may provide himself with a last suited to his foot size and have this last used for the making of several shoes, the inner soles of which may vary, one from the other, according to the degree to which his foot is yieldingi to treatment and thereforerequires either more or less support from the hump or boss on the inner sole ofthe shoe.
Myy invention may be more fully understood by reference to the accompanying drawinggin which Figure l is a side View of my shoe. last with a part of the side broken away to show theI boss-forming member, Fig. 2 is a bottom View.
Similar letters refer both figures.
The wooden last A is made and shaped in the usual manner excepting that its bottom is provided with a large cavity a which is normally covered by the metal plate B which is bent so as top-resent a depression b in its under surface. This plate B is fastened by screws C to the wooden last so that its edges are flush with the bottom thereof which is slightly cut away to receive the to similar parts in plate as shown in Fig. l. The plate B is -also provided with perforations through which tacks may bedriven when the upper leather is pulled over and tacked to the bottom of the last according to the usual mauncr inmaking shoes. i
The metal plate B is preferably made of a strong, yet flexible, composition metal so that the depression Z) and the surface corr tour of the platel may be changed from time to time as may be desired. It is often desii-able to form a slight elevation lat one or both sides of the cavity b in order that a corresponding depression may beniade on the side or sidesof the inner sole. of a shoe and it is apparent that this may 'Ue easily accomplished by manipulation of the metal plate B which is readily removable from the wooden last by simply withdrawing the screws C; or another metal plate may be substituted with a surface of contour different from that formerly used. o
It will be apparent to those `familiar with the art of treating dislocated arches of the foot that the plate B as shown in the drawing` is located for constructing a shoe for the treatment-of the anterior transverse, or frontal arch. l do not, however. confine my invention to this use alone, it being' plain that the plateA B 'may be so positioned, by a different placement of the cavity a, that a last may be adapted for constructing a shoe for the treatment of the posterior transverse arch, or the longitudinal arch.
Havingthus fully described my invention whatl claim isl A shoe last. provided with a cavity in the bottom thereof and a removably mounted plate covering said cavity and having a surface of irregular contour arranged to be given different forms by depressing the same more or less into said cavity.
