March 1, 1938. H. V. S. MOTT SHOE FlTTING INDEX Filed Jan. 21, 1937 4 INVENToRQ l War/a5 HJ. /Vff A TTORNEYS.

Patented Mar. 1, 1938 UNITED STATES Parleur oFFlcE 14 Claims.

This invention relates to an index device for use in assuring a correct fitting of the foet to footwear; and has for one of its objects to provide means permanently associated with the shoe structure and capable of giving a visual indication of the exact position of the foot within the shoe upon exposure to Roentgen or X-rays for accurately determining with reference to the usual or common measuring standard of sizes taken from lasts in ratio to the shoe whether or not a proper tting of a shoe is obtained.

Another object of the invention is to provide means incorporated in a shoe which is opaque or impermeable to Roentgen or X-rays and capable of being readily differentiated from the permeable parts of the shoe structure and the fleshy and boney structures of the foot, and also be responsive to lateral movement of the foot and move relative to a f xed standard of comparison within the shoe to indicate the exact position of the functioning foot in the shoe.

Another object of the invention is to provide means opaque or impermeable to Roentgen or X-rays and movable laterally of the shoe in accordance with any transverse expansionv of the inner and outer sides of the shoe upper due to filling the same' so that a visual determination of said extent of such movement relative to a stationary index corresponding to the extreme widths of the functioning foot may be observed upon exposure to X-rays in order to indicate the comparative positions of the outlying marginal transverse side portions of the foot with reference to the stationary index whereby an accurate determination of the foot tting is secured.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

As is well known, one method of shoe ttlng practiced in some of the shoe stores has been to employ the use of Roentgen-rays or an X-ray device for visually determining the -fit of footwear. According to this method, the foot during a trial fitting with a shoe of supposedly the correct size is exposed to X-rays, at which time an obser-- vation is made of the shadows of the foot and shoe structures which are cast upon a fluorescent screen. However, the results obtained from the use of such apparatus have not been satisfactory since difliculty has been experienced in determining the exact foot measurements or of locating the positions of its'marginal portions in the shoe owing to the confused or indistinct appearance of the portions of the shadows which represent the outer eshy parts of the foot and the contiguous parts of the shoe upper, which parts of the foot and shoe structures are not of sufiiciently different densities to the passage of Roentgen or X-rays to show strong contrast in the shadows cast on the screen; and in order to overcome these prior diflculties and to the end that an accurate determination of the exact location of the functioning foot in the shoe may be assured, and also that an indication of correct fitting of the foot may be clearly and distinctly shown on the fluorescent screen, I dispose marker or index means, opaque to Roentgen4 or X-rays, within or on the shoe structure above the sole portion thereof and near the outer borders of the foot, and the character of said marker means is such as to be clearly dis-- tinguishable from the shoe and foot structures when exposed and examined under the action of the X-rays; and the marker index means which I employ may comprise two or more index members placed within or on the shoe upper above the sole, each ofwhich is disposed in close adjacency to a side portion of the foot, preferably at the extreme width position thereof, or in proximate relation to the rst and ilfth metatarso-phalangeal joints thereof; and said marker index members may each take the form of a dense member. opaque to X-rays and disposed longitudinally of the shoe at each side of the foot, within or on the .side walls of the'shoe upper and located in a proper position with respect to the extreme width y of the foot and to be close to its outer borders; and these markers preferably should be of such a character that they will be permitted to move in action with any lateral expansion ofthe side portions of the upper due to iilling of the shoe by the foot during a trial iitting. In order that an accurate means of measurement may be had to determine the extent of such lateral movement and correct fitting of the foot, I further provide index means opaque to X-rays and positioned in or on the sole of the shoe in a predetermined xed relation thereon, preferably at theextremewidth position thereof; and said sole index means are so positioned with respect to the sole as to be laterally removed from the borders of the bones of the first and ilfth metatarso-phalangealioints so that the extreme outer borders of said sole index means bear a coincident relation to the soft tissues and extreme width of the foot at. such positions while said border portions of said index means are each normally in an aligned relation with its respective index member of the shoe' upper which is disposed at the same side of the sh when correct shoe fitting is obtained; and I preferably make the lateral distance between the extreme outer border edges of said sole index means to correspond exactly with the extreme width measurements of the particular shoe and predetermined by the shoe manufacturer as being correct and proper for that size and last of shoe; and I may also place an opaque marker or index member at the tip end of the shoe either in or on the sole or above the latter and in or on the end wall of the tip or toe cap of the shoe upper in order to demonstrate sufficient length beyond the ends of the toes; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawing, the numeral I8 designates the upper of a shoe which is usually made of a pliable material, such as leather, and provided with an inner lining II composed of a fabric material suitably secured thereto. Afflxed to the upper Il is the usual leather sole I2 consisting of an insole I3. a slipsole Il and an out'- sole II, the latter being composed usually of leather,.although various rubber compositions or other suitable footwear materials may serve for this purpose.

As one embodiment of my invention I have shown in Figs. 1 to 5 of the drawing a shoe structure in which there is provided a pair of marker index members I1 and I8 `which are positioned within or on the sides of the upper I I and they are preferably so located as to be close -to the sides of the foot and disposed at each side thereof. The members I1 and I8 are of similar construction and may comprise a body opaque or impermeable to X-rays, and preferably of a metallic character, such as a metal strip, wire, foil,

an impregnated or. coated fabric material, or other dense materials or substances which are capable of being easily distinguished from the foot and the shoe materials when exposed to the action of the X-rays. As shown in Figs. 2 and 3, the index members I1 and I8 are each embedded or inserted between the innermost layers of the shoe upper III nearest to the skin of the foot and they are each located above the sole of the shoe and extend in a general longitudinal direction of the shoe from heel to toe and lie substantially in a plane passing through the general medial areas of the joints and extending laterally of the articulations of the first and fifth metatarso-phalangeal joints of the foot. As shown in the drawing, the index I1 is located between the layers of or embedded within the outside wall of the shoe upper whereas the other index member I8 is similarly arranged Within the inside shoe wall.

In order that there may be obtained an accurate determination of the extent of lateral movement of the marker index members I1 and I8 and also in order to properly locate the same when a correct fitting of the foot has been effected, I have provided two fixed or stationary index members 20 which are disposed in the sole of the shoe at positions transversely thereof near the outer borders of the foot and at locations corresponding to the extreme width of foot for the particular size and last of shoe being made. 'I'he index members 28 may each comprise a small body of any suitable dense material which is opaque to X-rays, such as a piece of metal or vulcanized rubber, and may be of any desired form and size, such as a wire or iiat strip,

which permits them to be positioned on or in the sole so as to be disposed below and be com'- pletely removed laterally from the borders of the bones of the foot and thus be located solely beneath the soft tissues of the first and fifth toes at the extreme outer borders thereof so as to bear coincident relation thereto. The index members 20 may be embedded in the sole of the shoe so as to be entirely disposed laterally thereof and lie at the sides and below the first and fth metatarso-phalangeal joints so as to be coincident with the marginal edgesor outer borders of the soft tissues of the foot and corresponding to the extreme width position of the foot. 'I'he members 20 are thus positioned in or on the shoe sole so that they will be in alignment with the movable index members I1 and I8 respectively when examined under the action of X-rays, as shown inA Fig. 4, and thus will indicate on a uorescent screen the extreme width of the functioning foot and the location of the outer borders ofgthe fleshy portions thereof, and also give an indication when a correct iit is had in the shoe.

InFigs. 2 and 3 the positions of the little and great toes respectively, are shown in dotted outline and designated by the numerals 23 and 24 respectively, in order to show their proper positions when correct shoe fitting results. l

It will therefore be seen that a correct fit of theV shoe is obtained only when each of the index members I1 and I8 respectively is in alignment with an index member 20 disposed in the sole at the same side of the shoe, as shown in Fig. 4. However, should the shoe be too narrow in width or nt the foot too tightly then the side walls of the upper will consequently expand outwardly in the course of 'which lateral movement of the index members I1 and I8 will occur in opposite directions and away from the fixed index members 20, as shown in Fig. 5, to visually indicate the position of the foot within the shoe, when viewed to X-rays, and the extent of improper tting or the presence of a mist.

or impermeable to X-rays, such as lead, vulcanv ized rubber and other materials capable of being visually differentiated under the action of X-rays from the structures of the foot and shoe and/or show strong contrast on a fluorescent screen.

The strip 25 is preferably made of a length as to extend beyond the joint between the first metatarsal bone and the proximal phalangeal bone of the first or great toe, and extends transversely across the shoe so as to extend beyond the joint between the fifth metatarsal bone and the proximal phalangeal bone of the fifth or little toe. In Fig. 7 the position of the great toe is indicated in dotted outline and designated by the numeral 23 to show its relation to the shoe structure when a correct fitting is obtained. Thus, the sole index member 25 is intended to properly locate the position Aof the functioning foot Within the shoe in generally the same manner, as that illustrated in Figs. 4 and 5 when the separate index members are used,l and accordingly, the member will indicate correct shoe fitting when the side index pieces I1 and I8 are in alignment with the tips of this transverse sole member 25.

If desired, the opaque sole strip 25 may be further provided with permeable size markings, such as perforations, whereby the size of the shoe will be visibly indicated or shown in the X-ray shadow on the uorescent screen.

As illustrated in dotted outline in Figs. 4 and 5, a xed index piece 2I also composed of an opaque material may be placed at the tip or forward end of the shoe either on or in the sole or above the sole and on or in the toe cap to indicate and locate the amount of length or clearance beyond the distal ends of the toes or digits of the foot.

In accordance with this invention I have thus provided means of improving and facilitating the art and practice of shoe fitting by incorporating relatively movable opaque structures in shoes in such accurate relationship to important foot measurements that those people, experienced or l inexperienced in shoe fitting and interested in the purchasing or sale of shoes can see with the use of X-rays vand uorescent screen that the shoe ts the foot correctly. g

In accordance with my invention I have therefore provided not only a means which responds to expansive movements of the side walls of the shoe upper but also one which is capable of bemeasurements of thefoot to the extreme outer borders of the soft tissues and skin beyond the. lateral borders of the bones of the first and fth metatarso-phalangeal joints.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the device is susceptible,.the invention being defined and limited only by the terms of the 'appended claims.
