SHOE

Filed Sept. 2, 1930' Patented Mar. 31, 1936 N'ro STATS PAT SHOE

Robert McCulloch, Fort William,

Ontario, Canada Claims.

This present invention relates to certain new and useful improvements in a shoe.

The primary object of the invention resides in the provision of a shoe which is of improved construction and gives more comfort to the wearer than the shoes now in general use.

The invention has for another object the provision of a shoe of the character stated in which the sole is improved and constructed in such a manner as to prevent the formation of lumps or ridges in the toe and curling up of the edge of the insole.

The invention has for a further object the provision of a shoe of the character stated in which the sole is constructed to permit a double flexing thereof during walking and thus supporting the arch of the foot in a natural manner.

The invention has for a still further object the provision of a shoe of the character stated having a sole which is flexible throughout its entire length and substantial in construction, thus forming a soft but firm support for the sole of the foot while the shoe is worn.

The invention has for a still further object the provision of a shoe of the character stated in which the entire inner sole is flexible and free from lumps or curled edges during the entire life of the shoe, thus presenting a flexible smooth support for the sole of the foot while the wearer is standing or walking and thus providing a shoe which will not cause an uneven pressure against nerves of the foot or cause the development and formation of callouses or other foot troubles.

A still further object of the invention resides in the pro-vision of a shoe of the character stated in which the improved insole structure may be readily incorporated in the shoe without materially altering the style or formation of the shoe.

The invention has for a still further object the provision of a shoe of the character stated which will not only give the desired smooth support for the sole of the foot and permit free double flexing of the sole while walking to gently massage the bottom of the foot without irritating the same but will also absorb moisture from the foot without in turn causing absorption of leather dyes and the like by the foot, as occurs at the present time with any type of shoes now in general use.

The invention has for a. still further object the provision of a shoe of the character stated which may be manufactured at a reasonable cost and sold at a popular price with good profit, thus providing a commercially attractive proposition.

To the accomplishment of these and related objects as shall become apparent as the description proceeds, my invention resides in the constructon; combination and arrangement of parts as shall be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

The invention will be best understood and can be more clearly described when reference is had to the drawing forming a part of this disclosure, wherein like characters indicate like parts throughout the several views.

In the drawing:-

Figure 1 is a bottom plan of the improved inner sole for the shoe;

Figure 2 is a longitudinal vertical section through the complete shoe with the improved inner sole incorporated therein; and

Figure 3 is a transverse vertical section, taken substantially on the plane of line 3-3 of Figure 2, looking in the direction indicated by the arrows.

Referring more in detail to the drawing, it is to be noted that the insole E is composed of chrome tanned cowhide or other appropriate material which will not crack or curl up at the edges. The underlining I of leather is stitched in the usual Way to the insole and the edge 8 thereof turned down, except at the heel portion. This underlining T is covered with canvas 9, except at the flat heel portion and the channel formed under the ball and instep portion by turning down the edge 8 of the underlining l is filled with a single strip of sheet cork I!) held in place around its edges vn'th a compound of cork and tar i i. Thus the strip of sheet cork It and canvas 9 are interposed between the insole 6 and the outer sole l2, which is secured in place in the usual and well known manner. The welt strip I3 is also mounted suitably on the upper face of the outer sole l2, along the forward end and side edges thereof to the heel portion of the shoe. The shoe upper I4 is brought down and turned under between the outer sole l2 and the edge of the insole 6 and secured thereto by stitching or other appropriate means. The welt strip I3 may then be readily secured on the outer sole 52 by stitching or other means. The remainder of the shoe may be assembled and finished in any suitable or appropriate manner.

As the construction of the device has thus been described in detail, brief reference is now had to its use and modus operandi: This shoe structure provides a smooth soft sole which is exceptionally flexible and pliable and remains in that condition throughout the life of the shoe. By applying the chome tanned cowhide for the inner sole 6, the canvas covering 9 for the underside and the single strip of sheet cork I0, the shoe sole will not work into lumps or ridges under the foot and. curling up of the edges of the inner sole 6 is also impossible. This combination and arrangement of co-operating elements for building up the sole of the shoe also permits a double flexing of the inner sole 6 as the heel is raised and the weight of the wearer thrown onto the ball of the foot in walking. As the toe of the shoe turns up by the weight of the wearer resting on the ball portion of the foot, the intermediate or instep portion of the inner sole 6 rises, slightly and gently massaging the instep on the bottom of the foot and supporting the same without irritating the foot. Excessive moisture from the foot is absorbed by the chrome tanned cowhide inner sole 6 without absorption into the foot of leather dyes and impurities. The single strip of cork I 0 serving as the filler between the inner sole 6 and the outer sole I2 retains its shape and character throughout the life of the shoe and does not work up into lumps or ridges but permits the foot to have a smooth even support under the sole of the foot, the entire length and width thereof. Furthermore, as it is impossible for the edge of the chrome tanned cowhide 6 to curl up at the edges either when being worn or when the shoe is temporarily laid aside, it is thus impossible for the shoe to develop raised portions within the same along the edge of the inner sole 6.

From the foregoing description taken in connection with the accompanying drawing, it will be manifest that a shoe is provided that will fulfill all the necessary requirements of such a device but as many changes could be made in the above descriptiomand many apparently widely different embodiments of my invention may be constructed within the scope of the appended claims without departing from the spirit or scope thereof. It is intended that all matters contained in the said accompanying specification and drawing shall be interpreted as illustrative and not in a limited sense.

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

1. In a shoe structure, a double flexing chrome tanned leather inner-sole having a noncurlable edge, a leather pocket with a downturned edge under said chrome tanned inner-sole, a flanged canvas cover underlining for said leather pocket, a single strip sheet cork filler held in said canvas lined pocket, a welt stitched to said inner-sole, and an outer sole stitched to said welt and contacting with said single strip sheet cork filler.

2. In a shoe structure, a double flexing inner sole comprising a single strip sheet cork member, surrounded on its top and edges by a canvas liner and a chrome-tanned leather insole with a leather under-piece flanged around its edges to provide a pocket in which said canvas is secured; and an outer sole covering said sheet cork member and the perimeters of said flanged leather underpiece and canvas lining.

3. In a shoe structure, a double-flexing chrome tanned leather insole, an inverted leather pocket underlying the same and on which said chrome tanned leather insole is supported, a canvas lining for said pocket flanged downwards around its edges engaging the entire interior surfaces of said pocket, and a single strip sheet cork filler held in said flanged canvas lining.

4. In a shoe structure, an inner sole comprising a leather pocket surfaced with a double flexing piece of chrome tanned leather, said pocket being inverted, a canvas lining for said pocket flanged downwards around its edges engaging the entire interior surfaces of said pocket, and a single strip sheet cork filler held in said flanged canvas linlng.

5. In a shoe structure, in combination with an upper, a welt and an outer sole; an inverted leather pocket; a canvas lining therefor and a sheet cork filler in said canvas lined leather pocket; and a double flexing chrome tanned leather insole overlying said inverted cork filled canvas lined leather pocket and extending beyond the perimeters thereof to overlie and be stretched to the inturned lower edges of said upper.
