ARTIFICIAL FOOT AND SHOE.
E PECIPICATION forming part of Letters Patent No. 299,158, dated May 27, 188
Application filed February 9, 18s.). (No model.)
To all whom it may concern:
Be it known that I, EDWARD L. OCONNOR, of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Artificial Feet and Shoes, of which the following is a specification.
The object of my invention is to provide a shoe or boot which shall take the place of the thick cork soles or iron frames now employed by persons having one leg shorter than the other, and which shall, when on the foot of the wearer, have every appearance of an ordinary shoe or boot, the filling or artificial foot contained in said shoe or boot being jointed to re semble the joints of the natural foot, enabling the wearer to walk with ease and comparative grace.
A great many people object to wearing a thick cork sole or iron frame attached to the shoe, as it presents an unsightly appearance, and also when this last-named shoe or frame is worn by a gentleman one leg of the pants must be cut shorter than the other. Vith my invention the thick cork sole and iron frame are dispensed with, and to outward.a1: pearances the crippled foot presents the same appearance as the other foot.
Referring to the drawings forming part of this specification, Figure 1, Sheet 1, is an elevation of the shoe complete. Fig. 2-, Sheet 1, represents a man wearing my improved shoe. Fig. 3, Sheet 1, represents a man wearing a shoe with a cork sole. Fig. 4, Sheet 1, represents an iron frame attached to a shoe, and the position it occupies and the appearance it presents upon the foot of a man in a standing position. Fig. 5, Sheet 2, represents the false foot or filling of the shoe, showing the position occupied by the foot of the wearer. Fig. 6, Sheet 2, represents a vertical transverse sec tion through the false foot in front of the instep, taken at the line :0 m of Fig. 5. Fig. 7, Sheet 3, is a perspective view of the framework of the false foot. Fig. 8, Sheet 8, is a vertical longitudinal section of the false feet.
This false foot A is made in sections, the said sections being jointed together to permit the foot to operate after the manner of the natural foot, and to accommodate itself to the movements of the natural foot, which it is to I support. The heel-sectiona is preferably hollowed out, as shown, forming a cavity, (1, surrounded by walls a. One or more toe-sections, b, are provided, all of which sections are secured to a sole-plate, B, preferably made of spring-steel. The front end of the heelsection a. is covered with a metal plate, B, and the ends of the toe-section b and the inner end of the toe-sections O are each covered with a metal plate, as B. Spaces f are left between the various sections of the foot, and in each of these spaces f are placed and suitably secured the springs D, preferably spiral, and there being preferably two of these springs placed in each space f in the present instance. In order to retain these springs in position, a bolt, d, passes through each spring, one end of each bolt being secured to one of the plates B the other end of said bolt passing through the plate at the opposite side of the space f and being free to move longitudinally through the last-namedplate as the springs D are compressed. These toesections I) may also, if desired, be hollow as well as the heel-section a, and especially may this be the case if the foot is to be worn by a very light or weak person. If, however, the person is very heavy, or has a great deal of walking to do, all of the sections, both heel and toe, are preferably made solid. The toe-sections being secured to the spring-plate B,the false foot is prevented from bending, the springs D between the toesections and the heel-section being compressed. The spring-plate B and the springs D at all times have a tendency to keep the foot straight; but when the wearer raises his heel his weight rests mostly upon the toe-sections, and the plate B is bent and the springs D are compressed, the false foot thus imitating very closethe weight is taken off from the toe the springplate B and the springs d straighten the foot again.
The heel-section a may, if desired, be made in one piece complete; but I prefer to make it in two pieces, as shown, the lower portion, 0, being surmounted by an upper portion, pref erably a block, E, which latter is connected to the portion 0 by a hinge, c, the pivotal point of said hinge being at the front end of the block E. hen the heel-section is made ly the movement of the natural foot, and when in two pieces hinged together,'as described, a bolt, F, is passed down through an opening, f, in the portion E and through the portion-e, and is secured to the sole-plate B, the upper end of the bolt F being provided with a head or nut, F. In order to leave the upper surface of the portion E smooth and unobstructed, this head or nut F is sunk slightly below said upper surface, and the bolt F, below this head, is surrounded by a spring, G, which is compressed between the head F of the bolt F and the bot tom of the opening or recess f in the block E. In the present instance the bottom of this opening is formed by one side of the hinge 0; but, if desired, the opening f may be so constructed near the bottom as to form a shoulder upon which the spring G may rest. A shoulder or projection is preferably connected to portion E to prevent the head of the bolt from slipping down too far. This spring G, being compressed between the head of the bolt F and the bottom of the opening f, tends at all times to keep the block E in contact with the lower portion 0 of the heel-section a;
' heel-section.
but by further compression of the spring the back edge of said block is permitted to move slightly away from the lower portion, 0, of the The purpose of this movement is to prevent any sudden jerk on the foot and leg of the wearer when the toe of the false foot steps 011 a raised projection of any description. This joint in the heel-section also makes the ankle of the false foot more nearly like the ankle of the natural foot, thus permitting more freedom of motion. In the present instance the great toe 7c is supposed to rest just over the space between the heel-section a and the adjoining toe-section b. (See particularly Fig. 5.)
That surface m of the false foot (see Fig. 8)
on which the foot rests is shaped, as shown,
to correspond with the sole or bottom of the natural foot, the thickness of the heel section or sections 0 and E, when there are two or more, being increased to compensate for the shortening of the leg.
A covering, H, preferably of leather, is placed over the upper surface of the false foot, and upon this covering is preferably laid a soft packing, H, of wool, felt, or other soft material to form an easy resting-place for the foot of the wearer. Then the natural foot is in position upon the false foot, the line of the instep is but very little altered, as will be seen from an inspection of Fig. 5, the thick portion of the instep and ankle being raised above its natural position. The heel of the natural foot, however, will project rearward slightly beyond the natural rear line of the ankle; but this projection will be entirely hid by the clothing of the wearer.
The shoe J, into which this false foot and and the natural foot are to be introduced, is shown complete in Fig. 1. The top a of this shoe is made high enough to extend above the ankle of the natural foot when in position therein, and is preferably laced up in front, but may, if desired, be buttoned.
In the interior of the rear part of the top is a pocket or recess, p, in which the heel of the natural foot rests when in position on the false foot.
In each side of the upper end of the top a is preferably placed an elastic webbing, K, which causes the top of the shoe to fit more snugly around the foot of wearer when the foot is in position and the shoe laced. The front of this top n is shaped to accurately fit the instep of the natural foot, which latter is therefore held securely in the shoe.
As an additional means for securingthe natural foot in the shoe and to the false foot,
an ankle-support, L, may be connectedto the heel-section a, which ankle-support fits up around the ankle of the wearer, as shown in Fig. 5. This ankle-support L may, however, be dispensed with, if desired, and the foot of the wearer will be held in the shoe by' the upper a. g
It will be obvious that the false foot may be placed in a boot instead of a 'shoe, the boot being formed tofit the false foot, and also to fit the natural foot inserted therein, in a manner similar to that shown in connection with the shoe and its upper. The upper of the foot is to be provided with the reeessp. This false foot, having been properly formed, is placedin the shoe or boot and remainsthere, not being withdrawn with the foot of the wearer.
By the use of my invention the shoe presents no unsightly appearance, and the wearer is allowed much more freedom of motion than is permitted by the cork sole or iron frame,
as the wearer has every use of his foot that he would have if it were fiat on the floor, and the wearer can therefore walk, run, or'dance with almost as much freedom as a person without deformity. hen preferred, an 6X- terior separate boot or shoe may be dispensed with, and the leather or equivalent material may be permanently connected to and built onto the false foot.
"While the various features of my invention are preferably employed together, as shown, one or more of them may be used separately, and, when desired, in connection, so far as applicable, with other artificial feet and other shoes and boots, than such as are herein shown.
What I claim as new and of my invention, and desire to secure by Letters Patent, is
1. The artificial foot A, consisting of aheelsection, a, and one or more toe-sections, b, said sections being connected by a spring-connection, to permit the foot to bend in imitation of the natural foot, the surface on of said an tificial foot being shaped to correspond with the bottom of the natural foot, and adapted to receive said natural foot, substantially as and for the purposes specified.
2. The artificial foot A, consisting of the heelsection c and the toe section or sections 2), said sections being secured to a spring soleplate, B, and separated by spaces, in which spaces are placed springs D, capable of being compressed between the sections when the foot is bent, substantially as and for the purposes specified.
3. The combination of the heel-section a, having plate B, and the toe section or sections b, having plates B, said sections being secured to a plate, 13, and the springs D, located between said heel and toe sections, and retained in position by the rods or bolts (1, substantially as and for the purposes specified.
4. In an artificial foot, the heelsection (1, consisting of the lower portion or base, 6, and the upper portion or block, E, the two portions being hinged together at the front edge of said block by a hinge, c, substantially as and for the purposes specified.
5. The heel-section a, consisting of the base 6 and the block E, hinged together, as described, in combination with the bolt F, passing through said block and base, and secured to the plate B, and the spring G, located in the recess f in the block E, and surrounding the upper end of the bolt F, and compressed between the head F of said bolt and the bottom of the recess f, substantially as and for the purposes specified.
6. In combination with a false foot provided with a surface, m, shaped substantially as shown, and terminating at rear above the ordinary heel portion of a shoe or boot, the upper 02, provided with recess 1), and for the purposes specified.
