Application led August 7, 1915.

To @ZZ whom/'15 may concern:

Be it known that I, JAMES WV. FRANKLIN, a citizen of the UnitedK States, residing at Bristol, county of Bristol, State of Rhode Island, have invented certain new and useful Improvements in Boots or Shoes, of which-the following is a full, clear, and eX act description.

This invention relates to boots and shoes, more particularly to shoes ofthat general type having a rubber sole and a fabric upper.

It is customary in constructing a shoe of this type to form the sole of such length that it extends throughout the entire ball, shank and heel portion of the upper. The sole is secured to the upper partially by cementing to the insole, and partially by a rubber strip known as foxing, which extends along the wall of the upper and unites the edge of the rubber sole to the sides of the upper. A rubber heel of the hollow or lshell type, which has been previously molded and partially vulcanized, is secured to the heel portion of the sole by cementing its concave top surface throughout to the bottom face of the heel portion of thesole, and during vulcanization of the article, the heel becomes united to the sole, the considerable contacting surfaces of the heel portion of the sole and the rubber heel being depended upon to make a irm joint between the' sole and heel.

The disadvantage hitherto existing in a shoe constructed as above described, is that it has been impossible to obtain a non-separable joint between the heel portion of the solel and the rubber heel. -Furthermore, the edge of the heel portion of the sole has always existed as an unsightly ledge at the base of the counter of the shoe.

To obviate the above described disadvantages `my present invention provides an 'integral strip of rubber extending upwardly from the concave top surface of the heel and lying substantially flush with the'outer wall of the heel, this strip being of suflicieut height to extend up over the upper or the heel foxing of the shoe, as the case may be, and serving to localize the attachment of the rubber heel upon the upper Specication of Letters Patent.

itself, as distinguished from vattaching the heel tothe sole, as hitherto. To accommodate this novel heel construction, I discon- J tinue the heel portion of the sole at, and

countersink the same in, the front wall of the rubber heel, where it is securely united to the heel. As a result, a great saving of stock is effected in the use of this short rubber sole, over the use of the usual long rubber sole, which extends back over the entire top surface of the rubber heel.

For a detailed description of the invention reference may bfc had to the following specification and to the accompanying drawing forming a part thereof, in which- Figure 1 is a view in elevation showing a rubber sole canvas shoe embodying my improvements; Fig. 2 is a fragmentary longitudinal sectional view through the shoe shown in Fig. 1; Fig. 3 is a plan view of the assembled rubber sole and heel constructed in accordance with my invention: Fig. 4is a View in elevation looking toward the front wall of the rubber heel. Fig. 5

is a plan view of a modified form of heel. l

Fig. 6 is a fragmentary sectional view of the modified form shown in Fig. 5.

Referring to the drawing, in which like characters of reference designate similar parts, 10 designates the ordinary fabric.v

such as canvas, upper of a shoe.

In carrying out my invention, I provide a rubber heel 11, preferably of the hollow or interior chamber, or shell construction shown, but not necessarily so, and which is preferably molded and preferably partially cured, the mold sections being so constructed that anI upstanding strip 1Q. of rubber exists around the edge of the concave top surneat appearing and strong joint with the upper, as will be hereinafter more fully described. The heel is formed furthermore with a countersink or recess 15 in the top surface of `its front wall 1l. and into this countersink I fit and preferably cement the rear end portion 16 of a rubber sole 1T, the latter being preferably in a raw or green state, so that the joint between the sole and licei becomes integral and unitary during vulcanization of the article. It will be noted especially that the heel portion of the rubber sole is only about half an inch more or less in length and extends only upon the front wall of the rubber heel, consequently. a great saving in rubber stock is effected over the usual construction without sacrificing strength or durability in the article.

As shown in Fig. the front Wall of the heel may be formed underneath the recess 15 with an integral forwardly extending horizontally disposed rubber strip 12 which overlaps the shanlcportion of the rubber sole and' strengthens the joint between the sole and heel. l

In building the shoe, the bottom edge of the upper is turned inwardly underneath the insole 18 and is preferably cemented to the latter. Below and cemented to, or otherwise united to the insole, is the usual filler 19, ordinarily formed of rag stock and provided on the bottom face with a rubberized fabric layer 20, which, during vulcanizatiou of the shoe, gives a firm bond between the rubber sole and the filler. A strip of foxing 21, of raw rubber, is run entirely7 around the toe, arch, and heel portions of the upper and is turned underneath the insole. The sole and heel,` which are preferably separately assembled, although not necessarily so, are now applied, the heel being positioned so that the upstanding rubber strip 12 contacts with the heel foxing of the upper, and the sole being positioned to contact with the toe and instep foxing, as shown. Preferably, the entire top surface of the rubber sole and top surface of the heel, as well the inner surface of the upstanding strip 1Q, are cemented before application to the shoe, so that during vulcanization the firm` est union between the various parts will be infoduced. 'rl`o ci niplete the article, the saine is placed in the heater or vuli'fanizer and vulcanized.

By virtue ol the upstauding strip 12 ol" thc rubber heel. extending up a considerable distance over thc hecl loxing and being united duringvulcanization in integral unitary association therewith. the heel will he firmly attaclud 'to the upper at a localized portion at the base ol4 the counter of the upper. Thus the joint between the rubber heel and the upp'cr localised on the wall of the upper entirely above the top surface of the heel, in contradistinction to the joint being below the rubber sole itself, as hitherto.

From the above description, and by reference` to the accompanying drawings, itwill be clearly evident that the product is devoid of the usual unsightly joint made by a rubber sole extending over the entire top face of the heel, and that the strip 12 forming as it does a continuation of the heel, produces a neat appearing joint that is iush with the'wall of the upper.

The constructions above described result in a shoe that is not only pleasing in appearance and comfortable to the wearer, but which is also very durable, as it has been found that the upper is firmly united to the l heel by the methods employed as above described, and the usual separable strata of sole and heel positively obviated.

Although the invention may find its widest application as applied to rubber sole shoes,l it also may be applied to an overshoe or a rubber boot, and it will be understood that although the invention is particularly described and illustrated in the drawings as embodied in a rubber sole fabric upper shoe, it is not designed to be restricted thereto, but may be embodied in an overshoe, a ruimer boot. or in fact any article of footwear.

l beliexe that l am the first to produce an article characterized by the features particularly pointed out above, and therefore, l do not limit myself to the exact construetion described and illustrated, it being understood that modifications may be resorted to within the scope of the appended claims. without departing from the spirit or sacrilicing any of the advantages of the invention.

What is claimed is:

1. A shoe comprising an upper, a heel having vertical and bottom walls defining an interior chamber, an upstanding rubber strip integral with and extending above the top surface of said wall and attaching said heel to said upper above said surface, there being a counter-sink formed in said surface, and a sole attached to said upper and having a short heel portion fitting in said countersink.

2. shoe comprising a fabric upper, a rubber heel, an upstanding rubber strip extending around the sides and back of said heel and terminating at the front of said heel and attaching the heel to the counter portion of the upper above the top surface of' the heel, and a rubber sole attached to said upper and to said licei and terminating near the terminals of said strip.

i. A shoe comprising a fabric upper, a concave rubber heel having an integral U-shaped upstanding rubber strip extend- 10 extending above the top surface of the, heel and uniting the heel to the Wall of the upper above the top surface cf the heel, and hmvving an integral strip extending forwardly from the front Wall, and a rubber sole se- -cured to the upper and tc the heel, said forwardly extending strip overlapping and being secured to said sole.
