12' Claims;

This invention relates to lasts for making shoes, boots: and. similar articles of footwear. and, my present last is a; distinct and practical improvement to overcome certain practical objections to, and defects in my lastconstruction shown U. S..Letters; Patent #151920 1 andin other lasts as now universally used in shoe factories.

object of the invention is toprovid'e a last witha. metallic heel plate having a tubular post supported in suchfashion by the heel section of a last as to prevent the heel section. of a wooden last: from cracking, splitting, crushing, or otherwise becoming deformed. under the pressure of nailing machines, or other shoe. makingdev-ice, which has a tendency to materially shorten the life-of the present types. of- -wooden lasts now employedinshoe factories. j v An object: of the invention. resides in attaching the-metallic heel plate to the wooden heel section of. the; last insuch. a'fashion as to cause an edge thereof to'bite. into the wooden material to provide a tight joint between such elements. and thereby prevent lining and leather fragments from finding their way under the heel plate.

Another object; of the invention resides providing. the heel. plate and tubular post with a bracing wing, or wings and through anopening, or openings therein accommodate a. hinge pin also receivable in aligned openings in the heel section of the last.

A. further object of my invention is to provide a last which is. light in weight strong-and durable, highly e-fiicient for the purpose. designed and comparatively cheap in cost of manufacture. With the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and .finally pointed out in the. claims hereto appended.

Referring to the accompanying drawing forming. apart. of this specification'wherein like characters. of reference denote similar parts through.- .out. the several views: 7

Fig. l is a. View partly in-sectional' elevation and partly in side elevation of a. last embodying the features of my invention.

Fig. .2 is a transverse verticalsectional' view of a part of. the heelsection of the last.

Fig.3 is.- a plan view}, partly. in section. of the heel section of..-the last showing one form of hinge member connection.

Fig. l-isa viewfsimiiar to Fig. 3 showing a modified. form of hinge member connection In the drawing, the reference character I designates a'member having a lastsupportingpin 2..

The reference character it designates" the: heel section of a wooden last; 4 designates the frontsection. of the; lastandi 5 designates a suitable hinge memberconnecting' two: last sections.

The heel section 3 of the last is provided with a suitable bore fi extending, from the curved face 1 to the flat face 8 thereof. A suitable tubular post like member 9: is frictionally insertable into the bore: 6 and one end of the tubularmemberis: provided with a suitable heel, plate H1; The tubu lar post 9 may have: outer face tapered and also, if desired-,the outer face of thepostqnray be provided with suitable projections I I; to prevent rotary displacement of the post. 9. relative to the heel section-30f the last. It alsoserves-to more. securely hold the post. against longitudinal displacement due to the frictional resistance that is set up between thepost and the: wall of the. bore in the heel section 3 :of the. last.

The. inner. marginal edge of. the heelbplate l 7 is slightly beveled, or flanged, as. at l2, so .as..to. provide apenetrating edgeH-l to bite into the .material of the heelseatsurface of. the last section 3v and to form a tight joint between the. biting. edge of the metal plate and the wooden heel section 3 of the last. This arrangement prevents fabric shoe lining and leather fragmentsfrom finding their way between the plate and heel sections of the last, and thereby overcomes a common nuisance now contended with when removing shoes from their lasts.

A suitable brace wing M, as. shown in Fig; 4,, or a pair of brace wings M, as shown in Fig. 3; connect. the front end portion of the metal heel plate ID with. the tubular post Sand serves to reinforce such structure. In the .case where the front last section 4 is connected to the heel section. 3 of a two piece wooden last by means of a suitable hinge connection 5,v the pin |5,, which connects the hinge member to the last section 3, passes through an opening IS in the brace-Wings M, or wings M", as well as in aligned openings [6 in the last section 3 and this serves to reinforce the rear hinge connection'and prevent the last from cracking, -or splitting adjacent the rear hinge. connection, and also serves as additional meansto prevent displacementof. the heel plate and. its post. relative. to the heel section 30f; the last. v v

f It will be noted that 'the tubular post -9 is provided with two bores designated. Hand 1 8'providing a suitable shoulder .l9 atthe juncture thereof. The bore of larger diameter and'greater length designated llserves to receive the p in ;2

on the support I for supporting the last in position. The bore l8 which is relatively smaller than bore I1 is employed for the purpose of permitting a suitable screw to be received therein when the last and the shoe thereon have been removed from the supporting pin 2. This screw (not shown), is adapted to be screwed into a suitable shoe heel positioned on the heel seat of the shoe for initially securing the shoe heel to the shoe prior to a final heel nailing operation.

It will be noted that the smaller bore l 8 isopen at its outer end to the heel plate Ill and the outer end of the bore I! is open to and flush with the face 8 of the heel section 3 of the last.

It will be observed that any pressure appliedto the heel plate In is transmitted through. the tubular post 9, thus it takes up the shock that would otherwise be transmitted directly to the wooden heel section 3 of the last. It will be observed that the free end face of the tubular post 9 lies flush with the face 8 of the heel section of the last.

It is to be understood that my invention is equally applicable to a one piece or block last.

From the foregoing description, it is apparent that I provide a heel section for a wooden last that will not be constantly breaking down under pressure of nailing machines and other shoe making devices by splitting of the wood and by its sagging out of shape, as the structure shown and described eliminates these weaknesses which. are found in the present last constructions.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertainsl From the foregoing description, it isevident that a simple device for thiscpurpose has been disclosed, but it is to be understood that I do. not desire to restrict, or limit myself to the very details of the construction shown and described, which is merely illustrative, it being obvious that changes, not involving the exercise of invention, may be made without conflicting or departing from the spirit of the invention within the scope of the appended claims.
