Definitions

  • a machine for simultaneously applying attaching pressure on the sole and heel breast of cement lasted shoes is provided with a back part heel support responsive to relative movement of sole pad elements and a shoe holding device, the mounting of the heel support being such as to accommodate the heel with increasing back-up pressure as attaching pressure is applied to the sole and heel breast.
  • Relative heightwise movement of the shoe being operated on causes the heel support to be pivoted about an axis widthwise of the shoe and simultaneously moved bodily heightwise thereof against the heel thereby to wrap about the heel back contour in a manner enabling increasing heel breast presure to be uniformly distributed while heel displacement on the shoe bottom is avoided.
  • the heel back-up mechanism includes a heel support cooperative with a shank presser pad and swingably mounted for embracing the back parts of heels, the support being pivotal on a fulcrum movable heightwise of the shoe in response to shoe movement during heightwise compression of the shank pad.
  • the present invention requires fewer parts, and the heel support is automatically caused by relative heightwise displacement of the shoe itself to embrace the rearward surface of the heel whereupon that surface can displace and/or bodily move the heel support in counterbalancing pressure applied to the heel breast flap.
  • the heel support mounted as described in the aforementioned patents could provide only such substantially constant counterbalancing pressure as yielding springs permitted, whereas in the arrangement now afforded the heel support automatically and appropriately increases its back-up support for the heel as the shoe assumes the final position for sole and heel flap attachment.
  • FIG. 1 is a view in front elevation of a shoe and heelsupporting pad box and shoe engaging and holding devices cooperative therewith, the parts being in inoperative position;
  • FIG. 2 is a view cor-responding to a right-hand portion of FIG. 1 but showing a different heel with a heel pad now shifted forwardly on its support means and in rest position;
  • FIG. 3 is a view corresponding to FIGS. 1 and 2, with portions in section, and showing a shoe under pressure in sole and breast flap attaching position, pressure distributing linkage now actuating the heel support;
  • FIGS. 4 and 5 illustrate in side elevation, two of many variant contours of different styles of heels.
  • the shoe to be operated upon, often having a high heel, has an upper 20 supported on a last 22 with an outsole 24 spotted in the shoe bottom.
  • the rearward end of the outsole is formed as a reduced portion or flap 26 for covering the usually arcuate front face or breast of the temporarily attached heel 12.
  • the pad box 14 is provided with a composite set of pad elements for accommodating the shoe bottom. These elements are protected by a leather cover 28 secured by a rim plate 30.
  • a forepart tray 32 (FIG. 1), a shank tray 34, and a heel supporting tray 36 are yieldingly held in the pad box in preliminary positions of adjustment.
  • the arrangement is such that the forepart and heel trays 32, 36 are relatively depressed when the shoe is brought under compression on the cover 28, components of the forces bearing on the forepart and heel being imparted through links and levers (largely as fully set forth in the Pat. 3,052,901)
  • the latter are fulcrumed on a shaft 48 rotatable in opposed side plates 50 (one shown in FIG. 1) constituting a base for the box 14.
  • Rearward ends of the levers 46 extend beneath forward arms of the shank tray 34.
  • This tray 34 is in the form of a wide lever pivoted on a shaft 52 extending widthwise of the shoe and journaled in the side plates 50.
  • a link 54 as set forth in the Pat. 3,052,901.
  • the heel support 10 which may be a rubber pad block of selected shape and suitable hardness to accommodate the back ends of the heels to be engaged thereby, it is formed with a widthwise kerf 57.
  • the support is tightly but detachably seated on a pair of aligned, widthwise-spaced upstanding ribs 56 (one shown) integral with the base of the heel tray 36, or when desired the support 10 may be entirely in the tray and retained by the ribs as shown in FIG. 1.
  • the tray 36 is pivotally supported on a pin 58 (FIGS.
  • the heel tray 36 with its support 10 may be readily removed and interchanged with another corresponding assembly when desired and without disassembling the machine since front leg portions 78 of the tray 36 are formed with open-ended bearing slots 80 (only one shown) for receiving the pin 58.
  • the limit of counterclockwise movement of the heel tray with respect to the bell crank lever 62, 64 is determined by engagement of a flat under surface of the portions 78 with a flat 82 on the lever. It is to be noted, however, that a limit of counterclockwise movement of the heel tray is not finally determined until, in the unusual condition, the arm 62 abuts a block 84 (FIGS.
  • the support 10 is bodily movable heightwise of the shoe as well as pivotally about a widthwise axis during pressure engagement with the heel. This combined motion enables the support 10 to accommodate various heels by further concentrating pressure on the breast surface as an increase of pressure on the rear surface of the heel is applied.
  • a machine for applying pressure simultaneously to a shoe bottom and to the breast of a heel attached to the shoe bottom said machine having a pad box relatively movable with respect to cooperative toe and heel engaging devices and including forepart, shank, and heel pressing elements, in combination with a pressure distributing linkage for applying pressure to the shank of a shoe when pressure is applied to the forepart and heel portion thereof, the heel pressing element being pivotally supported on said linkage for movement bodily heightwise of the shoe during application of said shank pressure and for movement about an axis extendingwidthwise of the shoe to embrace the rearward surface of the heel.
  • a machine for applying pressure simultaneously to a shoe bottom and to the breast of a heel attached to the shoe bottom said machine having a pad box relatively movable with respect to cooperative toe and heel engaging devices and including forepart, shank, and heel pressing elements, in combination
  • a pressure distributing means including a forepart tray for the forepart pressing elements and a shank tray for the shank pressing elements, said trays being interconnected, and a heel support operable to embrace the rearward surface of the heel when attaching pressure is exerted by the forepart and shank pressing elements, said heel support being mounted in a heel tray, a bell crank lever fulcrumed in the pad box and pivotally connected to the shank tray, means pivotally mounting the heel tray on an arm of the bell crank lever for movement about an axis extending widthwise of the shoe, and yieldable means connected to said lever for resisting movement of the heel support bodily heightwise of the shoe when the latter and the pad box are relatively moved heightwise.
  • a resilient heel support having an under portion formed with a kerf, a
  • heel tray pivotally mounted for carrying the heel support, said tray having a pair of front aligned ribs extending widthwise of a shoe to be operated upon for retaining the support on the tray or optionally seating in said kerf to retain the support in a second position.
  • a pad box having side enclosing means for confining vertically disposed independent shank engaging elements and a breast flap pressing member, a heel support cooperative with the flap pressing member to hold a heel against displacement relative to its shoe on the pad box, and pivotally related means for simultaneously pressing the shank engaging elements, the flap pressing member and the heel support against the shoe, and means for mounting said heel support, on being engaged by the rearward surface of the heel, for yielding movement heightwise of the shoe and for pivotal movement about an axis extending widthwise of the shoe to cause increasing pressure to be applied by the heel support against the rearward surface of the heel at the desired point on the heel as said pressing member increases its pressure on the flap.
