UNITED STATES EDWARD B. HAFERTEPEN, OF CINCINNATI, OHIO.

BOOT AND SHOE.

Specification of Letters Patent.

Patented July 18, 1922.

Application filed August 23, 1920. Serial No. 405,213.

To all whom it may concern Be it known that I, EDWARD B. Hiirnn'rn- PEN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Boots and Shoes, of which the following is a specification.

My invention relates to novel means for correcting and supporting fallen arches of the feet.

The flexible arch-support shoes now on the market have a tendency, after the newness is worn off, to sag and lose the benefit for which they were intended. In the making of such flexible arch-support shoes, the last upon which they are constructed is hollowed out in the shank to allow the molding of a high arch in their construction. This molding of the shank being done while the leather is very wet allows the formation of an arch support, but after short wear by feet which are flat and have fallen arches, the tendency of the shoes is to fall back to the natural position of the fiat leather of which they are made, and lose the benefits entirely for which they are built.

The object of my invention is to overcome the foregoing objection and to provide av comfortable bandagelike resilient shoe whereby the arch support is adapted to maintain its position under continued use and to firmly and yet slightly resiliently support the arch of the foot in its proper position.

My invention consists in constructing the shoe of the welt, turned or McKay type in the usual manner, except that a firmly and closely woven heavy fabric, such as duck or canvas. or a heavy strong leather or other equivalent shank-piece is inserted between the outer and inner sole. or above the sole of a turned shoe, as the case may be, and extending from over the heel to the ball of the shoe, and stitched therein by a row of stitches extending entirely through said inner and outer soles and shank-piece or through said sole and shank-piece, as the case may be, entirely around near the edge of said shankpiece to firmly hold said shank-piece and soles together while the inner and outer soles are in their properly formed or molded wet condition, thereby preventing any lowering or sagging of the arch, then reinserting the last in the shoe and allowing it to dry and set in its proper arched positionv My invention further consists in constructing the shoe with my improved arch so that when finished the inner side of the ball of the shoe will be a trifle higher than the outer side, compelling the foot with fallen arch to assume its normal position and tread.

My invention also consists in the peculiar construction, combination and arrangement of parts and in the method employed in producing the shoe.

In the drawings:

Fig. 1 is a bottom view of a welt shoe with outer sole turned back and showing the shank-piece in position;

Fig. 2 is a bottom view of the shank;

Fig. 3 is a side elevation of a portion of the left shoe showing the position is assumes upon the floor before the weight of the user is placed thereon; and

Fig. 4 is a bottom view showing the stitches by which the shank-piece and inner and outer soles are held in fixed relation to one another, the dotted line showing the position of the stitching above the heel.

In the embodiment of my invention as illustrated and which shows a preferred construction, I have used the welt type of shoe, in which the upper 10, insole 11 and welt 12 are stitched together in the usual manner. I then insert a shank-piece 13 of firmly and closely woven heavy fabric, such as canvas or duck, or a piece of heavy strong leather between the outer sole 14 and the insole 11, and in the space formed by the welt extending from near the back of the heel to the ball of the shoe and having its edges resting closely adjacent to the welt 12. The filler 16 is placed in the regular way and the outer sole 14 is then stitched to the welt 12 in the usual manner, after which the last is withdrawn. The shank is then sewed in position by a row of stitches 15 entirely around near its edge through the inner and outer sole and through said shank-piece while said soles are in a wet state in order to hold them in proper arched position to each other and to said shank-piece, after which the last is reinserted and the shoe is finished in the regular way.

This combination and arrangement of parts secured together under the conditions set forth results in forming a permanent slightly resilient bandagelike suspension arch-support which will maintain its predetermined position under long usage and will at the same time possess sufficient resiliency to always return to its normal predetermined position while yielding slightly under unusual downward pressure cit the toot.

The turned shoe is made in exactly the same way except that the shank-piece is stitched to the inside or the sole through and through therewith whereupon it is relasted and finished.

The firi'nly and closely woven fabric will overcome any sagging and will not give way under usage, but will maintain its supporting qualities.

An advantage of my improved construction is that my improved shank being strong and non-exoansible longitudinally and being iirmly anchored at both ends to the preformed arch, while at the same time possessing a slight degree of resiliency or elasticity between its anchored ends, terms a slightly resilient suspension arch having suillcient resiliency to recoil to its normal elevation after yielding slightly to any excessive pressure. v

By reference to Fig. 3 it will be seen that the inner side of the ballot the shoe is termed a trifle higher than the outer side which is normally held in that position by my iinproved arch and compels the foot with a -fallen arch to assume its normal tread, thereby correcting what is commonly called toeing in, and compelling the foot to follow the construction of the last, thereby making the user walk correctly. 7

It will be apparent that my invention is capable of some modification without dept ture from its scope or spirit, as tor instance, the material used in the construction of the shank-piece may be leather or heavy tabrii'i or any other similar material which is adapt ed to be sewed into posi' on throughout its length, whereby the arch is caused to maintain its suspensiondike normal resilient nonexpansiblc position, and the ssh ank-piece may be varied in length, width and thickness according to the size or other conditions oil the shoe.

The preferred material, so tar as I am at present aware, for the construction of the shanlnpiece consists of firmly and closely woven heavy tabfiic, such as canvas or duck for the reason that when it is sewed between the inner and outer soles or upon the sole, as the case may be, it is caused to be drawn more closely and firmly to the sole, thereby forming a closer union therebetween and entirely preventing the possibility of squeaking. The shank being inserted dry while the adjacent soles are bound thereto while wet and allowed to dry and set, overcomes any tendency or the soles to resume their natural fiat condition.

ll 'hat 1 claim as new by Letters Patent is:

l. A boot or shoe having the inner and outer soles made to conform to the shape of the last, a shank-piece sewed therebetween and extending from the heel of the shoe to the ball thereoi by stitches through and through said inner and outer soles and shankpieceadapted to'hind and hold said shankpiece and inner and outer soles in fixed rela tion to each other.

2. The herein described method of producing a boot or shoe with a shank piece which consists in inserting a shank-piece in the space within the welt and between the inner and outer soles extending from over the heel of the shoe to the ball thereof and stitching said soles and shank together through and through when said soles are in wet condition to retain the term in. which the shoe was molded, and then reinserting the last and al lowing the shank piece to dry and set in its preformed position.

A boot or shoe having a sole formed with. its inner side normally a trifle higher than its outer side, and a shank-piece firmly and fixedly secured to the sole throughout the, length of said shank-piece extending from the heel of the shoe to the ball thereof, whereby pressure of the toot upon the sole will throw the toe outwardly, subsi'l-ant-ially as set forth. and for the purposes specified.

l. in a. shoe, a shaukpiece tor a suspension arch comprising an elongated strip of rigidly and closel y woven heavy fabric such as canvas or duck which is adapted to be sewed throughout its length to and between the inner and outer soles as a support for the arch of the shoe.

5. A shank piece tor boots and shoes comprising a strip non-expai'isible lengthwise, and which is adapted to be stitched throughout its lei'igth to the inner and outer soles thinugh and through to form a suspended bandagelike arc-h.

6. A shoe having a shanlr piece stitched to the outer and inner soles throughand through substantially throughout its length,
