' resident of Brockton, county of Plymouth,

State of Massachusetts, have invented an Improvement in Shoes, of which the following description, in connection with the accompanying drawings, is a. specification, like `letters on the drawings representing like parts.

This invention relates to bootsl and shoes, and to a modified type of spring heel shoe which is preferably made by my novel process, as described and claimed in my copending'application Serial No. 772,984, filed June 11, 1913.

, As spring heel shoes have heretofore been made, it has been customary to spring" the sole around one or more heel lifts to constitute the heel, and in order t'omake such a shoe it has been usually found de sirable to out, split, or otherwise reduce the thickness of the outsole at the heel breast to facilitate the springing of the sole around the heel lift. This construction has resulted unsatisfactorily in reducing the thickness of the Wearing capacity *of the outsole vat theA heel portion. Furthermore, the spring heel type of shoe has usually been found suitable only for use in making childrens and iufants footwear, but the improved type of spring heel shoe of my invention is adapted for adult footwear. By the novel process described inmy copending application above identified, wherein the outsole is molded to conform to the nal position it occupies in a completed shoe, the entire thickness of the .outsole is utilized for wearing throughout the entire length, including the -heel and heel breast. Furthermore, such molding condenses the K sole and adds to its Wearing capacity.

My present improved shoe comprises a spring heel shoe which is also a cushion heel. shoe, and its construction provides a shoe of extreme flexibilityyof welt construction throughout both forepart and heel part; without a tack or nail anywhere within the shoe; and which also includes arch supporting and orthopedic features.

An important feature of the present shoe, as also vexplained in my copending application above mentioned, is that the molding of the outer sole acts to etfectually condense the leather, to increase the Wearing qualities thereof, and to aff'ord a' firm and-l hardened tread surface. gations which are ifndentedfin the tread surface of the. sole during this molding, the leather fiber isstill further compacted and condensed, thus affording an anti-slipping ldevice on the sol'e, which will?` not be worn off as quickly as if4 the molding was dispen'sed with.

Fu-rther'features of" the invention, novelcombinations of part-s, and details of construction, Will be hereinafter more fully pointed out andl claimed.

In the drawings, illustrating an athletic orthopedic shoe madeby my improved process, Figure 1 isa side view of such ashoe; Fig. 2 is a view of' the outer sole after it is molded, and with the cushion heel' lift applied thereto; Fig. 3- is a view of the bottom of the sole after it is 4molded and corrugated; and Fig. 4 is a view in cross section on the 'line 4-4 of Fig.3.

The shoe upper. is indicatedl at- 1, a usual type of oxford or low shoe being shown, the upper l being united to a channel insol'e 2 and a welt 3 by inseam stitchin 4,' as illustrated in F ig., 4. It will be un erstood that the welt groove or channelV in the insole 2 i's cut entirely around the heel in order to allow for the stitching of the Welt 3' entirely around the heel also, a stitched heel seat being thus provided in contra-distinction to the usual nailed heel seat. A suitable filling 5 may be applied to both forepart and heel part of the shoe, and the outsole 6, together with the cushion heel lift 7, which have been molded and cemented together as above explained", and constituting a combined heel and sole,

are then applied to the shoe and the outsole stitching 8 lis put in, throufrh the welt 3, the sole 6 and around the heelB portion through By the formation of corruthe cushion lift 7', also uniting the sole, heel lift and welt firmly together.

The shoe made by my improved process is of extreme flexibility, as Well as of the cushion heel type, said cushion being secured without nails, and, in fact, the entire shoe is completed by my process without anail or l tack being left 'in it. The cushion heel liftv 7 may be of' any suitable thickness desired, and While preferably of rubber or rubbercom osition, may be of other yielding and resilient material. The outsole stitchmw 8 which secures the cushion heel 7 to the slice permits the cushion to yield and be flexed f the heel.

n'itliout'any restraint and Without affecting the holding of the stitches. In the shoe herein illustrated it will be lseen that the heel breast 9 is 'preferably formed at an angle having the forwardly extended and thicker portion at the arch side 10 of the shoe thus causing the insole of a shoe to [it up snugly under the arch of the foot, and provide an arrch supporting, as Well as orthopedic. construction.

Preferably I 'make the shoe of the type herein shown without a shank stifener or the like rigid means, although such a stiicner could be employed if desired. My improved process, therefore, enables a cushion heel shoe to be lnade of thevspring heel type, suitable for adult wear, and furthermore provides an extremely flexible shoe and without a nail or tack in its entire construction. Furthermore, by molding the outer sole, as explained, I secure the advantages of the full limit of thickness and wearing |capability of the outer sole, both at the heel breast 0 and throughout the' entire extent of This is of great importance, as heretofore ithas been customary to cut the heel portion of a spring heel shoe at the heel breast and to decrease the wearing thickness of the sole at this point.

By employing a welt construction around the heel, the shoe can be readily repaired and the cushion heel lift 7 can be replaced, should it wear out before the outer sole. By having the cushion lift, however, thus protected between the outsole and the heel of the shoe, its wearing capacity is greatly lengthened and the full capacity of its yield or resilience is left unimpaired.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1,. A spring heel shoe, having, in combination, an upper, an insole, a Welt secured to said upper and insole, and extending around the entire peripher of the shoe bottom, a molded outsole secured to said Welt, said outsole having its heel portion offset below the level of the adjacent end of the shank portion to form a recess for a heel lift, the portion of the sole connecting said shank portion with said heel portion gradually increasing in depth from the outer side of the shank to the inner side thereof, and a heel lift secured in saidrecess of such dimensions that the upper surface of said lift is substantially flush with the upper surface of said shank along their contacting l edges.

Q. A spring heel shoe having, in combination, an upper, an insole, awelt secured to the upper and insole and extending around the entire periphery of the shoe bottom, a molded outsole having anti-slipping corrugations other,

molded therein, having its heel portion offset below the level of theadjacent end of the shank portion to form a recess of greater depth at one slde of the sole than at the and -having its heel breast inclined forwardly from the side of the recess of lesser depth to the side thereof of greater depth, and a cushion heel lift secured in said recess of such dimensions as to fill said recess, said outsole and heel lift being secured to said welt by outsole stitching.

3. A shoe having an upper, an insole, a welt secured to said upper and insole and extending entirely around the periphery of the shoe bottom, an outsole having its heel portion inclined transversely of the shoe to form a recessbetween said heel portion and the level of the adjacent end of the shank portion of the sole' of greater depth at one side of the sole than at the other, and a cushion heel lift in the form of a wedge secured in said recess, the thick end of said wedge lying in the deep portion of said recess at one side of the sole and the 'thin end lying in the shallow portion of said recess at the other side of the sole.

1. A shoe having an upper, an insole, a welt secured to said upper and insole and extending entirely around the periphery of the shoe bottoln, a molded leather outsole having its heel portion inclined transversely to the heel of the shoe to form a recess 'of greater depth on one' side than the other, a cushion wedge heel lift of correspondingly increased thickness on one side interposed between the sole and heel, and stitching uniting the welt, wedge heel lift, and outsole together.

5. A shoe having a leather outer sole molded along the tread surface thereof, and condensed by intersecting depressions indented in the tread face during the moldingoperation and forming a plurality of flat tread spaces between said depressions.

6. A shoe having a leather outer sole molded along the tread face thereof to form both a heel tread face and a forepart tread face, provided with a plurality of intersecting indentations in both said tread faces formed during thel molding operation and constituting condensed portions of the sole along the lines of such indentations and spaced flat tread surfaces between said indentations, whereby an antislipping tread face on a leather sole for both heel and forepartis provided.A

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
