GOODWIN, or HAVERH'ILL, MAssAoHUsETTs' Assieiion4 on, ONE-HALii To JOSEPH o. PARIS, on HAVERHILD, yivressncnnsirirrs vrioni) non sOLnPREssiNeMAOHINEs Appiicaiioainea August 15, 192s. serial No.: 299,844. Renewed January si, i930;v` Y 'l This invention relates particularly to a sole-leve1ing machine which includes an vin-y ner mold or form'on which a partially cornpleted shoe, without a heel, is supported, and

5 an outer mold having a molding face adapted to cooperate with the inner mold in leveling the outsole of the shoe, means being provided for moving one of said molds, relative to the other to compress the outsole, mold its outer face,y and press down the usual channel flap of the outsole.

The invention is embodied in a supplemental ,mold member adapted to bear on the heel end of the outer mold and cooperate therewith and with theinner mold in compressing and molding the heel end of the outsole, in such manner as to form thereon a convex heel seat conforming tothe recessed end of a Wood heel, and a transverse shoulder defining the forward lend of the heel seat and offset therefrom, to overlap the upper portion of the heel breast, so that the sole-- leveling operation provides the outsole with a heel seat adapted to closely lit the recessed end of the heel and form a close joint at the upper portionof the' breast thereof.

Of the accompanying drawings forming av part of this specification,"v l

Figure 1 is a side view, showing the outer and inner molds of a sole-'leveling machine in pressing relation witheach'other, and .a supplemental mold member `ernbodyingthe invention, a portion of a heelless shoe supported by the inner mold being shown by Online 6 -6 of Figshowing the heel end of the inner mold, the

heel'end of the outsole withits heel seat coml pleted, and a portion of a wood heel of the CubanV type seated on the heel seat and ready to be nailed thereto.

In the drawings, 12 designates theinner mold or form of a well known type of soleleveling machine, adaptedto support a partly completed'shoe without' a heel, the heel` end of the outsole being designated by 13, the.up.

per by 14, and the shank piece by 15. In preparing the outsole I skive the inner side of the'.l1eel end thereof, to provide it with a feather edge 16 (Figures 8, 9, and 10) which is-spaced'from the shank piece before the pressing operation,fas1showu by Figures 8 and 9. Y Y

17 designates the outer mold which hasfthe usual recessed molding face18 indicated; by Figure 5,-and bythe dotted line in Figure 1, and'adapted to exert leveling pressure on the( outsole,\as usual in sole leveling machines. The molds12 and lfmay be elements of the welly known Goodyear. direct leveling machine,l theri'nner mold 12 being horizontally movable and verticallyrimmovable, while the Outer mold 17- horizontally immovable and verticallyy movable so that a shoe may be applied to the inner mold whiler the latteris out of the path of the outer mold, and then be moved into said path preparatory to the leveling operation. Y

The" supplemental mold member charac-V n terizingy myV invention includes y, a plate 19,

Y offset from the face 18, The form and arrangement of said porti-ons are such that when the supplemental member bears on the outer mold, as indicated by Figures 1, 5 and 6, and the outer kand inner molds exert pressure onV the outsole, the supplemental mold compresses and molds the heel endfofthe outsole, the feather edge VV16` being pressed against the shank piece, as shown by Figures 7 and 10. At the same time, the thicker Aedge portions 21 indent the outer surface of the Outsole, and form thereon the transverse shoulder shown by Figure 10, said shoulder being composed of two portions 2a of maximum depth at the opposite edges of the outsole, and disappearing at the longitudinal center thereof. 'Said shoulder defines the forward end ofthe heel'seat, and is odset therefrom, so that when the recessed end of the Wood heel 25 is seated on the heel seat, the shoulder portions 24 overlap and snugly iit upper portions of the breast of the heel, as indicated by F ilgures'1() and 10a, a close Joint being thus formed at the intersection of the shank portion of the outsole with the upper portion of the. breast. i

' It will be seen that the heel seat and slioulders are formedV entirely by the sole-leveling operationfthelheel end of the outsole being adapted by th'efeather edge 16 to be conformed by the supplemental mold member to the vrecessed end 'of the heel 25, so that the usual cutting and trimming of the heel end of the outsole by a hand-operated knife, to enable it to conform to the recessed end of the heel is obviated. Such trimming isobjectionable, because of the time and labor,

and the liability of Verror involved thereby. The supplemental mold member may be maintained iii operative relation to the vouter mold 17 by any suitable means, the'preferred means being as next described.

The ends of the member are provided with upstandingears 28. Links 29 arefconnected by pivots 30 with the ears 28, and by pivotsV 31 with the'oi'i'ter 'mold 17.4 VThe length Jof the links is such they may be swung on the pivots 31, to carry the supplemental mold member away from the pressing face of the outer Vmold when the use of the supplemental member is not required.: The ears 28 are provided with slots 32, receiving the pivots 30, and permitting adjustment 'of the supplemental mold'memb'er. V Y

Spring detent-s 38 may be .provided to yieldingly holdthe supplemental mold in its operative position, said detents 'being fixed to opposite sides ofthe outer mold member and adapted tov yieldinglyen'gage V'the links 29.

Another detent 33a may be provided to yieldingly hold the supplement-al mold in its inoperative position, as shown at the left-hand portion of Figure 1. The innermold niember may be provided with a marking die 34, adapted to indent the inner surface of a sha-nk piece supported by said-member, and thus .mark the shank piece 15, to indicate the size of the shoe. g Y. K u

ItV is obvious that Vmy invention is not limited to the preparation 4of heel seats for Cub-an Aheels, and may be adapted to prepare seatsfor full'Louis and half Louis heels.

g claim :V Y

1. A supplemental mold-member' formed to compress and mold the heel end of the outsole of a'supported shoe, to form thereon a heel seat conforming to the recessed Vend of a wood heel, and a transverse shoulder defining the forward end of the heel seat and offset therefrom, to overlap the upper portionof the heel breast, said member being provided n with means whereby it may be engaged with the outer mold. of a sole-leveling machine,

and located in its operative .positionrelative j to said mold, said member being la plate formed to extend across the'heel lend ofthe outer mold face, and havingv a rear end formed to be seated on said face, and aV forward edge including relatively thick shoul'- der-forming end portions, and a curved vthin- W, L L

edged central portion odset from said race.

2. The combination with the outer mold of a'sole-leveling machine, of a supplemental;

mold member formed to bear onk and extend across the heel portionof said mold-and cooperate therewith iii forming, on the heel end of the outsole of a shoe supported by the inner mold of themachine, a heel seat conforming`v to the recessed end of a wood heel, and a transverse shoulder defining the forward-endY of the heel seat and oEset therefrom, to bear on the upper portion of the heel breast, and

means niovablyconnecting said member with i heel breast, said member having upstanding ears, at its opposite ends, and` links pivoted to said ears vand tothe outer mold, said links permitting the location of the mold member in its operative position relative to the outer mold, and its removal from said position.

In testimony whereof I have aiiixed my signature.

EDWARD eoonwiN.
