Where lorthopedic appliances are to be used in conjunction with the foot for relieving the discomforts` of. and for correcting the deformity caused bybroken or fallen arches, it is highly desirable not only -to provide a support for the broken or weakened arch of the foot but to provide a cushion for the heel bone of the foot. In addition, it is highly desirable to maintain an exact relation 'between the arch support and the seat for the heel bone which relation differs for diierent feet. The present invention provides an extremely simple and effective appliance in which these various advantages are readily procured. n

v For the purpose of illustrating the application of my invention', I have shown in the drawing an ordinary shoe 10 consisting of a sole 11 and having a heel 12 attached thereto. The shoe l0 further comprises the usual uppers 13 including the quarters 14 and the cap 15 which may all be constructed in the usual manner. 'Inasmuch as the construction of the shoe does not form any particular feature of this invention, I have only shown Ythe shoe diagrammatically without indicating the hreo An object of the lnvention resides 1n reducing -par'tlcular Constructwn t e It will presently become apparent that the invention may be used with any type or form of shoe.

In order. to more fully comprehend the application anduse of the invention, I have shown diagrammatically thefoot 16 of the wearer within the shoe 10. In addition, I have illustrated in dotted lineslthe variouslbones of the foot. The lo() tibia is indicated at 17 While the iibula and the anges'. Where the condition of flat feet or broken arch occurs,` the cuneiforrn and scaphoid bones ydrop causing the abnormal condition which I am ablegt@ correct withtne'instantinvention. `In the 110 drawing, bones are illustrated as held in proper position with my appliance.

The invention proper is constructed with rights and lefts and is also made in various sizes to lt different feet. In Figs. 2 and 3 I have shown in perspective a right appliance and a left appliance. Inasmuch as both of these appliances are identical in construction excepting as to the differences pointed out,'only that shown in Fig. 2 will be described in detail. The appliance comprises a heel pad 25 and an arch support 26 which are integrally connected together. These structures are formed with a common cushion member2'7jl constructed of felt or some other suitable material having considerable resiliency and yet sufcient body to form a support forthe foot of the wearer.

lower surface of this cushion member is disposed a facing 29. These two facings are preferably constructed of leather or some other flexible and wear resisting sheet material and serve to hold the cushion member intact. The facings 28 and 29 may be cemented or stitched to the cushion member 28 or the same may be secured together in any suitable manner to form a 'composite rigid construction. 1

The heel pad 25 is constructed inthe shape of the heel of a shoe having the posterior portion thereof indicated at 30 curved and with the interior and exterior lateral edges 3l and 32 extending in a longitudinal direction. The heel pad 25 terminates at the Aanterior portion thereof along a line 33 which is situated in proximity to the cuneiform bones of the foot and which extends from the outer lateral edge of the appliance laterally inwardly.' The arch support 26 is constructed so as to form a continuation of the heel pad 25 and has its interior lateral edge 34 extending in continuation of the edge 32 of the heel pad 25. This structure terminates at the interior thereof along a longitudinal line 35 which is disposed in proximity to the medial plane of the foot of the wearer and which extends from the edge 33 of the heel pad 25 in an anterior direction longitudinally of the appliance. The extreme edge 36 of the arch support 26 iscurved from the edge 35 to the tip 37 thereof meeting the outer edge 34.

In the construction of the heel pad, the portions of the cushion member 27 which I have indicated at 38 and 39 and which follow along the line 33 of the heel pad 25 and line 35 of the arch support 25 are tapered or reduced in thickness as best shown in Figs. 4 and 5 so that the appliance gradually tapers down to a feather edge along these lines. If desired the edges Vof the facings 28 and 29 may be skved to further reduce the thickness of the appliance at these particular localities. y At a positionongthe arch support 26 immediately below the scaphoid bone 21 and rcuneiform bones 22 of Vthe foot is disposed an auxiliary cushion member 40 which is situated between the facing 29 and the cushion member 27. The construction of this member4 may best be seen lin Figs. 1 and 3. The cushion member 40'isconstructed with an edge 43 conforming injcurva- `ture with that of the edge 34 of the arch support 26 and is formed with a rounded edge 44 meeting the edge 43. This cushion member is preferably Vtapered or skived toward the edge 44'so that when the same` is inserted within the arch support a hump 42 is formed on Athe arch support `which tapers off gradually to the thickness of the major portion thereof. l

It can readily be comprehended that size and thickness of the pad 40 may be varied to meet with the requirement of the foot condition of the particular individual to whom the appliance is to be tted. The auxiliary cushion member 40 may be cemented or otherwise secured within the arch support so as to be held firmly in place.

. In the use of the invention, the appliances are selected to nt the particular shoe and foot of the The appliances are then merely placed wearers feet in the usual manner. In the ap- 32 and 34 of the same are disposed along the interior lateral portion 'of the shoe while the heel pad 25 is pulled well back into the shoe to t snugly within the same. Upon placing the weight of the feet upon the sole of the shoe and the appliances disposed within the same, the heel of the foot quickly forms a socket or depression in theheel pad which I have indicated at 41 in Fig. 4. This forms a seat `for the heel which assists in holding the appliance in place within the shoe and prevents movement of the appliance when the user is walking or standing upon his feet. The weight of the foot upon the other portions of the appliance causes the same to fit the anterior of the shoe and to conform to the shape of the foot of the wearer. From Figs. 1, 4 and 5, it will readily become apparent that the hump 42 formed on the arch support fits within the concavity of the arch and operates ina manner to lend support-to the bones of the footso as to relieve'the strain-imparted to the muscles and tendons of the foot.

My inventionis highly' advantageous inV that an extremely simple `and effective appliance is provided for supporting the arch of the foot of the wearer and for 'cushioning the heel thereof. The appliance may be constructed to t within 120 The particular pad and arch support are constructed all in one so that proper correlation of parts is v'The appliance is quite inconthe shoe is removed thereby making it extremely simple' and easy to use. The appliance is constructedsolely of flexible material and is readily molded when the weight of the foot is applied thereto to t the form to the form of the foot thereby making the device extremely easy to wear. The appliance is automatically held in vplace withinV the shoe through the weight of the foot upon the heel pad ofthe appliance so that the device is always inthe proper position to give the support and 'relief desired.

Changes in the vs'pecic Vform of my invention as herein described may be made within the scope of whatis claimed, without departing from the spirit of the invention. v

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

l. An article of the classdescribed comprising a facing having heel and soley portions adapted to lie uponvthe heel and sole of a shoe, said facing at 145 the sole portion thereof being of a width less than the width of the sole of the shoe and at the heel width of said facing at such locality, and means located in the heel portion of said facing having a cupped formation for engagement with the heel of the foot of the wearer for assisting in holding the sole portion and arch supporting pad in place within the shoe.

2. An article of the class described comprising upper and lower facings, said facings being .adapted to underlie the heel and instep of the foot of the wearer, said facings at the portion under the instep extending transversely from one lateral edge up to a medial longitudinal line and terminating at such line, said acings further extending completely across the heel, said facings at one side of the heel forming a continuation of the CHRIS J.
