  • the upper wall of the channel 22 is formed by the under face 36 of the lip 32 which is of less width than the upper portion of the breast 2i of the heel 20, and the width of the channel is substantially equal to the thickness of a normal outsole. In heels for womens shoes, for example, this thickness would be of the order of six or eight irons, more or less, as distinguished from that of a very thin piece of leather such as is commonly used to cover the breast of a heel.
  • the heel 20 may be described as having a solesupporting ledge or lower channel wall 38 which extends from one forward portion of the rim 40 of the attaching face 30 of the heel to the other, and an approximately vertical shoulder 42 which forms the bottom of the channel 22.

  • a pair of spaced milling cutters not shown
  • the heel blank 50 is then presented to a rotating tubular saw 54 (Fig. 3) of a channeling machine to form the heel blank 55 illustrated in Fig. 4.
  • the heel blank 50 may be supported in the channeling machine upon a table 58 carried by a slide 60 which is movable in directions 62 lengthwise of the tubular saw 54'.
  • the heel blank 50 is centralized in the channeling machine by suitable mechanism (not shown) with the breast edges 64 of the heel in engagement with a bar 66 which is used to locate theheel blank properly in the machine.
  • the channel 22 formed by'the rotating tubular saw 54 may be referred to as a cylindrical kerf the elements of which extend generally lengthwise of the heel. It may also be described as being of arcuate shape transversely of the heel and extending depthwise in a direction approximately parallel to the plane of the rim of the attaching face.
  • the top face 48"of the heel blank 55 is then presented to a concaving machine (not shown) slightly to concave the attaching face 30 v of the heel and to remove material from and concave the upper face of the lip 69 of the heel blank 55.
  • the upper face of the lip 32 Figs. 4 and 5) is therefore continuous with the attaching face 30 of the heel.
  • the rim 40 of the attaching face 30 of the heel 20 lies in a plane which is spaced from and overlies the lip 32.
  • the lip 32 may therefore be described as being located between the sole-receiving channel 22 and the plane of the rim of the attaching face of the heel.
  • the heel 20 may be covered by a single piece of covering material 68 (Fig. 7) I the forward margins of which are secured in overlapping relation to the breast 2i of the heel, the top margin of the cover being inturned upon and secured to the attaching face 30 of the heel and to the lower wall 38 of the channel 22, or it may be covered in any other suitable manner, or otherwise finished, as by lacquering.
  • the short outsole 24 of the shoe 26 has a rear or end face 12 which is located a short distance rearwardly of the heel-breast line of the sole. It is common practice to skive material from the lateral margins of the flesh side of the shank portion of the outsole before the same is attached to the shoe, thereby to provide the sole with beveled margins 13.
  • the outsole 24 is of substantially uniform width from its breast line 10 rearwardly.
  • the width of the rear portion of the outsole 24 of the shoe may be varied in accordance with the length of the channel 22 of the heel to be attached to the shoe, the proportions being such that the edges of the outsole of the finished shoe extend laterally approximately to, but not beyond, the breast corners 14 of the heel.
  • the heel seat (Fig. 8) of the shoe 26 may be built up by means of either a suitably shaped piece of sheet material or by using a mixture 18 of plastic material (Fig. 11) for example. cement andsawdust, which may be applied to the shoe by a machine such as that disclosed in application for United States Letters Patent Serial No. 81,299, filed May 22, 1936 in the name of John T. Lancaster.
  • the heel In order to position the covered heel 1i upon the shoe 2B preparatory to attaching the same to the shoe, the heel is' moved toward and forwardly of the prepared heel seat of the inverted shoe with its lip 32 tilted slightly downwardly, causing the lip to enter a cavity 16, between the rear end of the outsole 24 and the shoe bottom, and causing the rear portion of the outsole 24 to be engaged within the channel 22.
  • the heel When the heel has been moved to its proper position upon the shoe it is attached in any suitable way. If desired, a small quantity of the above-mentioned mixture of pyroxylin cement and sawdust in a moldable condition may be inserted in the cavity 16, just before the heel is positioned upon the shoe.
  • the width of the channel 22 may be varied to accommodate outsoles 24 of different thicknesses, and the curvature of the channel and therefore the under surface 36 of the lip 32 also may be varied in accordance with the transverse curvature of the shank portion of the outsole.
  • the lip of the heel be fairly rigid with relation to the remaining portion of the heel and that the channel 22 be narrow enough to be completely filled by the end of the sole 24, or even better that the sole be compressed somewhat by the channel, thereby forming a tight joint between the heel and the outsole. Since the channel 22 terminates inwardly attachment to shoes.
  • the channel 22 is illustrated as extending only a short distance rearwardly of the breast of the-heel, it is contemplated to increase the depth of the channel, if desired, and to drive and effectively formed in the stock fitting room and does not have to be trimmed for the reception of the covered heel II after attachment to the shoe upper..
  • a lacquered or painted heel 86 of the Louis type having in the upper portion of its breast a channel 88 con-. structed and arranged to receive the rear end of the short outsole.
  • the channel may be formed by presenting the Louis heel to the slotting machine indicated in Fig. 3.
  • the heel 06 may be described as having a cylindrical sole-en.- gaging ledge 90 which extends substantiallyfrom one of the forward portions of the rim of the attachingface 94 of the heel to the other. It will be noted that the marginal portions of the ledge are wider than the central portion of the ledge.
  • the upper wall 96 of the channel 80 is formed by the under side of a thin, narrow reenforcing lip 98 which extends a substantial distance forwardly of the upper breast corners I00 of the heel.
  • the forward edge I02 ofthe ledge 90 will override the entire width of the sole without the necessity of trimming the sole by hand after the sole has been applied to the shoe. If the margins of the shank portion of an outsole I04 attached to a shoe I05 are relatively thick, as
  • the rear. marginal .portions of the outsole preferably should be v 3
  • My invention makes it unnecessary to cover the breast offthe heel with a flap split from the outsole, thus permitting the use of short outsolesin the manufacture of. shoes having Louis heels, with a consequent saving even greater than when Cuban heels are used.
  • a shoe having a short outsole, and a heel having at the upper portion of its breast a lip which is of considerably less width than the breast of the heel and which extends a substantial distance forward of said breast and is located between the rear end portion of the short outsole and the shoe'bottom, said heel also having in the upper portion of its breast-a channel within which the rear end portion of said outsole is received, one wall of said channel being formed by said lip and the other wall of the channel extending from one side of the attaching face of the heel to the otherand providing a firm support for the rear end portion of the short outsole.
  • a shoe having a short outsole,.and a heel having a projecting lip which is of less width than the upper portion of the breast'of the heel, projects forward of the breast of the heel and is positioned between the outsole and the shoe bottom, said heel being provided with a channel in which the rear end of the short-outsole engages and which channel extends around the under face 'of the lip and terminates inwardly from the side faces of the heel.
