CUBOIDJVIUSCLE DEVELOPER.

Application led July 26, 1922. Serial No. 577,66.'

To all whom t may concern.'

Be it known that I, WILLIAM C. BURNS, a citizen of the United States, residing at Albany, in the county of Linn and State of Oregon, have invented new and useful Improvements in Cuboid-Muscle Developers, of which `the following is a specil'ication.

My present invention has reference to an appliance for footwear and is in the nature of a support of such construction as to slightly elevate the outer side of the foot to effectively contact with the portion of the foot below the cuboid bone, and by virtue of the pressure thereagainst to increase circulation to effectively develop the cords and muscles that support the cuboid bone as well as the other bones of the foot.

A further object is'toproduce a combined cuboid bone support and muscle developer for footwear which may be readily arranged in any construction of shoes and which cannot slip when in position.

A still further object is to produce an article of this character which shall be of an extremely simple construction, cheap to manufacture and market, and which shall be thoroughly efficient for the purpose devised. Y.

To the attainment of the foregoing, and other objects which will present themselves as the nature of the invention f is better understood, reference is to be had to the drawing in which there is illustrated a Satisfactory embodiment of the improvement reduced to practice.

In the drawing Figure l is a side elevation of the im. provement in applied position in a shoe, parts being broken away and parts being in section.

Figure 2 is a bottom plan View of the improvement.

Figure 3 is a fragmentary perspective view looking toward the inner face of theV inthe shoe, the beveled end 4 contacting reinforcement.

Figure 4 is a bottom plan view showing the support provided with transverse elevatin strips and with a leveler. y.

igure 5 is a sectional view on the line 5 5 of Figure 4, the dotted lines illustrating the shoe in which the device is arranged. Figure 6 is a sectional view on the line 6-f6 of Figure 5.

In constructing shoes and foot appliances for shoes, I have discovered that` the use or i walking onthe muscles that'holdthe cuboid bone in place increases the circulation to lan extent that the muscle tissues are builtup to an extent that will strengthen themuscles of the'feet and ankles, and as these muscles return to normal position they holdV the bones of the foot and ankle in normalposition so that the, cause of all foot troubles 4is thus removed. Therefore, I have termed, my improvement a cuboid muscle developer.

The improvement is ofa construction to relieve pressure of corns and callouses,and increases the wearof the shoe inasmuch as it carries most of the weight under thecuboid bone and muscles that hold the bone in place so that the foot is sustained straighter in the shoe, taking olf the pressure onthe toe and causing the shoe to wearmore even-on the'sole and heel. 'l v The support is made of two pieces fof leather, one of which constituting a body 1 Y upon which the foot rests, andthe other v being in the nature kof a reinforcing piece 2 which is adhesively secured to the under face of the vbody l by a water-proof cement. Such construction, it will be noted, is extremely simple, and may be cheaply manufactured,there being no stitchingbetween the parts, or analogous means for connecting the same. Y

By reference to the drawing, itwill be seen that the outer edge ofthe improvement is straight, and this edge is of course, disposed against'the outer side, of the shoe 3. The outer straight edge overcomes the `curved lines vof the shoe and extends out under tliemuscles of the cuboid bone of the foot. Both the body l and the reinforcing strip 2 have their longitudinal edges beveled inwardly, the body member l having its heel and front portion likewise beveled, the last A mentioned ybevel being, for distinction, vindi- `cated by the numeral 4. The beveled edges permit` of the'device being snugly received with the insole of the shoe, as clearly disclosed 1n Figure 1 of thedrawing.` The reinforcing strip 2 is disposed a slight dis- The outer lend of the reinforcementv 2 is curved, as at 5, to correspond withjthepcurv- Figure 3 of the drawing, and indicated byV ature of the outer end of the body 1, while nthe inner end is straight, and the said straight end is provided with a transverse concavity 6 which starts a slight distance from the straight edge of the 'said reinforcement, entering the opposite or curved edge thereof, the outer surface of the said' depression being concaved, as clearly illustrated in the numeral This depression Vtakes the VVdirect weightjoff of the cords of the foot that extends from the heel and serves to 'hold the bones of the foot properly positioned.

Under certain conditions I have found it "desirable to build beneath the vreinforcement 2, and as disclosed in Figures t and 5 and 6, I tack or VotherwiseV secure transversely adjacent the ends of the reinforcing strip 2 buildingV or elevating strips 8. These strips are comparatively thin and Vare constructed of leather. Any desired number' of strips may be arranged one over the other in accordance with foot conditions for the relief of foot troubles. In, ad-

dition to this, I have found it necessary under other causes'and conditions to arrange over'the building-stripsy 8a longitudinally disposed leveler 9. 'Ihis strip may be adjusted to either side vof the device and is designed to straighten the ankle. The depression 6 in the reinforcement 2 permits of the heel portion Vof the body being cupped by thepressure ofthe heel of the wearer thereagainst so that this construction also serves as a means for preventing.

the longitudinal displacement of the device in the shoe. The support cannot move laterally because of its contacting engagement with the sides of a shoe. Movement of the support longitudinally in the Vshoe is further prevented by the contacting engagement of Ythe, strips 8, the rounded end 5 of the reinforcement and the beveled end 4 of the body contacting with'the insole of the shoe. y n

The cause of so much foot trouble in the human family is the neglect of the use of the muscles that hold the cuboid bone in place. These muscles become weakened like any other muscles thaty are not used, and as the weight of the body presses the bones of the foot down and out of their natural position, the circulation is interfered with which causes the feet to tire quickly and become in a weakenedV condition. The weight is then' forced against the cords of the feet, which causes cramps in the feet `and the cords toache in the legs. This condition isfrequently lmistaken yfor rheumatism ofthe feet and legs and is effectively overcome" by inyimprovement.

.My improvement has the saine e'ect upon a'persons foot as were he Walking bare- 'footed' "soft earth, Yit *being well-known that barefooted children develop the muscles of their feet to the highest extent and it is only when they are forced to wear shoes that the muscles begin to deteriorate and foot troubles commence, and it is thought that the foregoing description, when taken in connection with the drawingwill fully setv forth the construction and advantages of the improvement to those skilled in the art to which suchv inventions relate.

Y Having Vdescribed theV invention,- I claim 1.
