The invention relatesto shoes .andmore partic- -Iularly to a heel construction therefor.
Themain object of the `'invention is toprovide a built-in shockv absorbing heel construction .which can: be readilyand expeditiously produced in a shoe factory, which provides a deep full shoe Width heel cushion, which insures a rm anchorageof the'upper, the counter, and the lining to the insole and the outsole of the shoe, and which because of the deep beveled edge of the cushion over and upon which the upper, its lining, and the counter are lasted provides a heel construction in which the cushion heel member is irmly anchored and yet does not itself oiTerdif-l culties in uniformity of product in massproduction and the maintenance of the shape of the shoe and does not change the size or shape of the shoe from that of the ordinary uncushioned shoes. Furthermore, with a beveled heel cushion g() sloping from the outer edge of the heel toward the thicker part of the cushion and against which the upper is lasted there is no tendency to create a hard ridge from the lasted over edge of the counter.
The invention further consists in the several features hereinafter set forth and more particuiarly defined by the claim at the conclusion hereof.
In the drawings:
Fig. 1 is a side elevation View of the heel portion of a shoe embodying the invention, parts being broken away and parts being shown in section;
Fig. 2 is a detailed sectional view taken on the line 2-2 of Fig. 1;
Fig. 3 is a detailed sectional View of certain of parts after the lasting operation;
Fig. 4 is a detailed perspective view of certain of the heel parts;
Fig. 5 is a bottom View of the heel construction shown in Fig. 1 with parts broken away and parts shown in section;
Fig. 6 is a view similar to Fig. 5 showing certain modifications;
Fig. 7 is a detailed perspective View of certain of the heel parts shown in Fig. 6.
Referring to Figs. 1 to 5, the numeral 8 designates a shape-determining insole, 9 the outsole,
I0 the upper, II the lining, I2 the counter, I3
the heel, I4 the heel base, I5 the steel shank stiffener, and IB the shock absorbing or cushioning heel member.
The cushioning heel member I6 is adapted to cover the area of the inner sole at the heel seat d and is cemented or rmly secured to the underside of saidinsole prior to assembly of the other parts of the shoe thereto. This member is preferably formed cf soft sponge rubber, though other suitable cushioning material may be used, and it is formed to provide a deep mid-portion I1, a beveled edge Iiirextending from its outer edge to said mid-portion and meeting a relatively straight edge portion I S which defines the bottom portion `2li of said cushion. It will be notedthat the edge I8 tapers to a thin outer edge. From the breast El of the heel the cushion tapers downwardly to the bottom portion 2t as indicated at 22, and this provides a surface against which the inclined end 23 oi' the shank stiffener labuts as shown in Fig. l.
In the making of the shoe, the insole 8 with the heel member Iii secured thereto is placed on the last with said heel member above said insole, and then the upper iii and its lining II is lasted over at the forepart and secured to the insole in any approved manner, but in the forming of the heel portion of the shoe the upper I0, its lining II, and the counter I2 are lasted over the beveled edge or side I8 of the heel member and secured thereto and to the insole 8 by tacks 24 or other suitable fastening means passing through all of these parts. At the completion of this lasting operation the inner edge 25 of the upper materials terminates adjacent the bottom portion which forms a marking edge for this purpose. Thereafter, the outsole 9 is secured to the insole at the forepart in any suitable manner, and at the heel seat is secured in position by nails 26 passing through said sole, the lasted over edges of the upper, lining, and counter, the beveled edge I8 of the heel member, and the inner sole against which they are clinched. Thereafter, the heel which may be of yleather or` rubber or leather and rubber is secured to the outsole in any suitable manner. For the purpose of illustration of one form of heel, we have shown a rubber heel I 3 with its heel base Ill secured to the shoe by nails 2l passing through these parts the outer sole, the lasted over edge of the upper, its lining and counter, the beveled edge I8 of the heel member, and the insole against which they are clinched.
In those types of shoes using a channelled insole 8', as in the Goodyear Welt type shoe, the
cushion heel member I6 is generally similar to the i'lrst described construction but as shown in Figs. 6 and 7 has portions of its beveled sides cut out adjacent the breast of the heel to form the recessesy 28 to allow the channelled edge v29 of the insole to extend to the heel, and the mid-portion of the cushion at the breast of the heel is provided With a shank positioning and receiving recess 30. In the Goodyear Welt type shoe the upper materials at the forepart and shank are lasted over the inner sole and secured to the channelled p0rtion thereof in the usual manner, and with the heel cushion forming part of this invention the upper materials including the counter are lasted `over the beveled edge I8 of the cushion member as in the rst described construction and secured thereto by tacks 24 and to the outer sole by nails 26 as in said previous construction, and then the heel I3 may be mounted on the shoe in any suitable manner. Y
In the attachment of the outer sole to the shoe the projecting bottom portion 2B will be more or less compressed so that the Vmid-portion of the Y cushion heel member will be somewhat compacted in the completed shoe, and this portion 2l) is- Furthermore, even not change the size or shape of the shoe from that of the uncushioned heel shoe. The construction also makes uniformity in mass production possible, and the lasting of the upper materials against the beveled edge of the cushion heel member prevents the formation of a hard ridge Where the heel fastenings pass through the shoe parts.
We desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such y limitations are included in the claim.
What We claim as our invention is:
Ina shoe, the combination of a channelled insole, a heel cushioning member secured to the underside of said insole at the he-el seat and covering said heel seat area and having a beveled outer edge and recessed portions at the breast of the heel seat and a shank positioning recess, an upper and its lining and a counter having their inturned edges at the heel seat lasted over and against said beveled edge, fastening means securing said lasted over parts to said cushion and to said insole, and an outsole connected to said lasted over parts, the cushion member, and said insole.
