COIL SPRING- LOIIGITTTDNAL ARCH SPPQRT Application led. September 8, 1930. Serial No. 380,752.

My invention relates to supports for supporting the longitudinal arch of the human foot, and more particularly relates to an improvement over my United States pat-ent issued June 10, 1930, under Patent Number One object of this invention is to provide a coil spring longitudinal arch support similar to the one covered in the above mentioned patent, but which will require no base between the spring and the insole of a shoe.

This is accomplished by thel provision of a plate extending across and connected to the largest and lowermost one of the springs coils for assisting in the adjustment of the throw of the spring. And also by the provision of an elastic section in the top member and surrounding the spring for permitting free action of the spring without its tending to force the support upwardly away from the insole of a shoe.

With these and other objects in view as will more fully appear, my invention consists in the construction, novel features, and 25 combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated in the accompanying one-sheet drawing, of which:

Figure l is a plan View of the support;

3@ Fig. 2 is a sectional view taken along the 'line 2 2 of Fig. l;

Fig.. 3 is a sectional view taken along the line 3 3 of Fig. l; and,

F ig. 4 is a top view of the spring showing the plate connecting opposite. sides of its largest and lowermost coil.

Like characters of reference designateV like parts in all the figures.

lt is understood that various changes in the form, proportion, size, shape, weight and other details of construction, within the scope oli my 'invention may be resorted to without departing from the spirit or broad principle offmy invention and without sacriiicing any of the advantages thereof; and it is also understood that the drawings are to be interpreted as being illustrative and not restrictive.

l One practical embodiment of the invention as illustrated in the drawings comprises:

lll

A top member 1, formed to substantially' lit the upper surface of an insole 2. Beneath the central portion of said top member 1, is provided a substantially conical coiled spring 3 the largest and lowermost coil of 55 which is connected at opposite sides by a plate 4 having a central pin 5 made integral therewith. Said top member l is bulged upwardly at its central portion to accommodate said spring 3,'and the bulged portion forms a cap 6 `for said spring.

Said cap 6 centrally supports the upper link of a chain 7 by a pin 8. Said chain 7 extends downwardly through said spring 3 and may be hooked over said pin 5 on plate @s 4 for controlling the throw of said spring 3.

Said top member 1 and said cap 6 are both preferably constructed of heavy canvas or leather and are not made integral with each' other, but are connected by a strip 9 ot some 70 resilient material such as rubber or the like which surrounds said cap 6 on three sides. Said strip 9 is securely` attached at its. outer edge to said top member Land at its inner edge to said cap 6 by cementing or the like.

In operation the spring 3 resiliently supports said cap 6 upon which the longitudinal archof the toot rests,whi1e strip 9 Ermits the cap 6 -to move with the arch of f foot while top member l is held stationary vby the w remainder of the foot.

Obviously, the invention is susceptible of embodiment in forms other than that which is illustrated in the accompanyingdrawings and described herein, and applicable for uses as and purposes other than as detailed, and l therefore consider as my own all such modifications and adaptations and other uses othe form oi the device herein described as fairly fall Within the scope of my invention. ee

Having thus described -my invention, what is claimed and desired to be secured by Letters Patent, is:

1. A coil spring longitudinal arch support embodying, a substantially conical coil an spring, a plate connecting opposite sides of the largest and lowermost coil of said spring,

a transverse pin carried centrally by said plate, a 'cap for said spring, a chain carried y said cap and adapted to engage said pin B for controlling the throat of said spring, a top member spacedly surrounding said cap on three sides and adapted to it the insole o a shoe, and a resilient strip connecting said 5 top member and said cap.

2. In a coil spring longitudinal arch support, the combination with a substantially conical spring for supporting the longitudinal arch of a human foot, o" a cap for said spring, a top member spacedly surrounding three sides of said cap and conforming to the shape of the insole of a shoe, and a resilient strip connecting the adjacent portions of said cap and said top member.

3. In a coil spring longitudinal arch support, the combination with a substantially conical spring for supporting the longitudinal arch of a human foot, of a plate extending between and attached to opposite sides of the largest and lowermost coil o said spring, a cap for the top of said spring, a chain carried by said cap and extending through said spring to said plate, means carried by said plate orengaging various links of said chain for limiting the throw of said spring, a top member spacedly surrounding a portion of said cap, and a resilient member connecting adjacent portions of said cap and said top member.

4. In a longitudinal arch support the combination with a resilient member for supporting the arch of a human foot7 a cap for said resilient member, and a base surrounding a portion of said cap, of an elastic strip connecting said base and said cap.
