Claims.

This invention relates to improvements in shoes andshoe bottom units. The invention is illustrated with special reference to its embodiment in shank pieces for turn shoes commonly known 5 as turn shanks although it may advantageously be embodied also in reinforced insoles for McKaysewed shoes or other shoes in which the insoles are initially cut substantially totheir finalmarginal contour.

One object of the present invention is to provide an improved shoe bottom unit for use in conjunction with a heel-attaching fastener to brace the heel and stiffen the shank portion of a shoe.

To the accomplishment of this object, one feal5 ture of the invention consists in a shoe bottom unit prepared for the reception of a heel fastener and comprising a shoe bottom piece, for example, a turn shank filler piece, a reinforcing or stiffening member, such as a metallic shank stifiener, located at the outer side of the shoe bottom piece and having a heel-fastener-receiving hole therein, and a heel-fastener-retaining member located at the inner side of the shoe bottom piece and having a heel-fastener-receiving hole therein, said members and the shoe bottom piece being secured together, with said holes in alinement and unobstructed, by means of one of said members extending through the shoe bottom piece and having holding engagement with the other of said members.

As herein illustrated, a heel-fastener is employed which consists of an ordinary wood screw and the heel-fastener-retaining member consists of a thin metallic plate having a hole which is smaller than the head of the screw so that the screw cannot be pulled outwardly through the shoe bottom piece but will be permanently retained in position to fasten the heel securely to the shoe. The illustrated .shoe bottom piece or .0 turn shank filler piece has a hole formed therein for receiving the screw and means is provided for securing together the component parts of the shoe bottom unit or turn shank piece consisting of prongs struck from the material of the screwfastener-retaining plate. The illustrated prongs project downwardly from the edge of the hole in the plate; extend through the hole in the filler piece and through the hole in the shankstiffener; are clenched over the edges ofthe hole in the shank stiffener; and are arranged around the edge of the hole so as not to interfere with the passage of the attaching screw therethrough. Also, as illustrated, the retaining plate is made large enough to serve as a clenching plate for lasting tacks employed to secure the upper to the filler piece, thereby insuring the production of a nailless heel seat in the shoe. Furthermore, the heel portion of the filler piece is preferably split to provide an integral flap for use in covering the clenching plate as well as the head of the heelo0 attaching screw.

Considered in another aspect, the invention resides also in a shoe having an improved shoe bottom unit incorporated therein, the shoe comprising a heel and a heel-attaching-fastener 05 which, as herein illustrated, extends through the component members of the shoe bottom unit and cooperates therewith in bracing the heel and stiffening the shank portion of the shoe.

The invention will be explained with reference to the accompanying drawing in which,

Fig. l is a perspective view of a shoe bottom unit I in the form of a shank piece for a turn shoe;

Fig. 2 is a bottom plan view of the turn shan piece shown in Fig. 1;

Fig. 3 is an edge view 'of the shank piece;

Fig. 4 is a sectional view, on an enlarged scale, taken along the line IVIV of Fig. 2;

Fig. 5 is a sectional view of a portion of a turn shoe having the improved shank piece incorac porated therein; and

Fig. 6 is a perspective view of the improved shoe bottom unit in the form of a reinforced insole for use in shoes other than turn shoes.

Referring first to Figs. 1 to 5, inclusive, which show the invention embodied in a composite shank piece for a turn shoe, the improved shank piece comprises a filler piece 10 made of leather board or other suitable material, a reinforcing member consisting of a metallic shank stiffener strip 12 which is located in a longitudinal groove 14 (Fig. 2) in the outer side of the filler piece, and a heel-fastener-retaining member consisting of a thin metallic plate 16 which is located at the inner side of the filler piece 10 beneath a thin flap 18 which is formed integrally with the filler piece by splitting the rear portion of the latter.- As shown, the filler piece 10 is shaped in marginal contour to correspond to the contour of the interior of the heel and shank portions of a shoe. 100 The shank stiffener 12 is made long enough to underlie the heel seat portion of the filler piece and the rear portion of the shank stiffener is provided with a circular aperture 20 (Fig. 2) for receiving a heel-atlaching screw 22 shown in Fig. 5. 105 The fastener-retaining plate 16 is shown as being cupped to conform to the convexity of the heel portion of the foot and it is provided with a circular aperture 2a for receiving a heel-attaching screw, the aperture being adapted, as herein-= 1 after explained to prevent the head of the attaching screw from being pulled outwardly through the plate 16 and thus the plate 16 serves to retain the screw in heel-attaching position in the shoe. As shown, the retaining plate 16 has a marginal contour corresponding to that of the heel portion of the filler piece 10, this construction adapting the retaining plate to serve also as a-clinching plate for clinching the points of the lasting tacks employed to secure the upper of the shoe to the filler piece. For the purpose of receiving clinching plate 16 at the edge ofthe hole 26, these prongs being conveniently formed by means of a punch die employed in making the hole 24.

In assembling the above described parts the clinching plate 16 is applied beneath the flap 1'8 with the prongs 28 extending through the hole 26 in the filler piece and the shank stiffener 12 is laid in the groove 14 of the filler piece, the hole 20 being placed over the outer ends of the prongs 28. The outer ends of the prongs 28 are then rolled over the edge of the hole 20 in the shank stiffener as shown Figs. 2 and 4, so as rigidly to secure both clinching plate 16 and the shank stiffener 12 to the filler piece with the holes in the clinching plate, the filler piece and the shank stiffener in coaxial alinement. The construction is such that lower portions of the prongs will snugly engage the shank of the heel-attaching screw, while the portions of the prongs adjacent to the clinching plate are curved or bent suificiently to provide a seat for the tapering lower faceof the head of the attaching screw.

In Fig. 5 the composite shank piece above-described is shown incorporated in a turn shoe comprising also an upper 30, a tread sole 32, and a heel 34. The margin of the upper 30, as shown, is lasted over the turn shank filler piece 10 and is secured to the latter by means of lasting tacks one of which is indicated at 36, the points of the lasting tacks being clinched over against the upper side of the fillerpiece by the action of the clinching plate 16 so that a nailless heel seat is provided within the s'hoe.. The heel attaching screw 22 extends through the hole 24 in the clinching plate 16,the hole 26 in the filler piece 10 and the hole 20 in the shank stifiener 12 and is screwed into the heel. The prongs 28 snugly embrace the shank portion of the screw 22 but are shaped near their base portions, as best shown in Fig. 4 to conform to the bevel of the head of the screw sothat the upper surface of the screw head will be substantially flush with the upper surface of the clinching plate 16. As shown, the head of the screw 22' and the upper surface of the clinching plate 16 are covered by means of the flap 18 of the filler piece so that'no metal is exposed and visible in the interior of the shoe bottom. The shank stiffener 12 is countersunk within the groove 14 to such an extent that its outer surface is substantially flush with the outer surface of the'filler piece thus enabling the tread sole to lie close to the filler piece. The countersinking of the shank stiffener in the filler piece also insures that the shank stifiener "i lll not interfere with the pulling over and lasting of the upper margins. The above-described construction is such that the heel-attaching screw co-operates with the'members of the composite shank piece in bracing the heel and stiffening the shank portion of the shoe.

The construction shown'in Fig. 6 is similar to that shown in Figs. 1 to 4, inclusive, except that the shank stiffener 12 and the clinching plate 16 are shown assembled with a full length insole 100 instead of a filler piece such as the filler piece 10. A shoe bottom unit is thus provided for use in shoes other than turn shoes, for example, Mc- Kay-sewed shoes and shoes wherein an outersole is secured to the shoe partiallyor wholly by means of cement.
