LEON LOBEL, 0F NEW YonigN. YM.

ARCH-SUPPORT.

Application filed .Tu1y'21,-1916.

To 1U/whom t may concern.'

Be it known that I, LEON LoBEL, a citizen of the United States of America, residing at New York city, county and State of New York, have invented certain new and useful Improvement-s in Arch-Supports, of which the following is a full, clear, and exact description.

This invention relates to improvements in arch-supports, and pertains more particularly to an auxiliary or supplemental yieldable supporting element designed to act i'n coperatlon" with the yieldable elements of an arch-supporter, which in turn are arranged t0 perform a kneading or massaging effect during the ambulatory movements of the. wearer. My present invention is intended to improve the construction of archsupporters described in United States Letters Patent `No. 1,129,089, dated February 16, 1915, and my invention consists, generally speaking, of a yieldable element or spring interposed between the base-plate and alining element contacting with the yieldable fingers which carry the covering or pad, the said yieldable element being arranged to be compressed and expand during the ambulatory movements of the wearer, rather than to swing. I am thus able to rovide a stiff but yieldable support for a bro en down arch which is better adapted to cushion shocks than a spring which is secured at one end thereof to the base-plate the free end of which is free to swing. A further object of my invention is to provide a special construction of the yieldable element or spring hereinabove referred to and means to permit adjustment thereof on the base-plate, for a pur ose which will be hereinafter describe I will now proceed to give a detailed description of my invention in connection with the accompanying drawing, forming part hereof, wherein- Figure l is a plan view of my improved arch-supporter, partly broken away t0 show the yieldable elements;

Fig. 2 is an enlarged cross-sectional view, the section being taken on a line 2-2 Fig. 1; @il

ig. 3 is a fragmentary side view looking in the direction of the arrow in Fig. 2.

Referring to the drawing, the supporter Specification of Letters Patent.

Patented June 12, 1917.

Serial No. 110,498.

comprises a base-plate 1 shaped to fit the sole of a shoe, 2 indicating a yieldable supporting element consisting of a plurality of independently yieldable fingers 3 carried by a plate 4 secured at 5 to the platel. The fingers 3 are shaped in such contour as to fit the arch of a foot and support the same. The fingers 3 are covered by a pad 6 of leather or the like, which is secured to the plate 1 by rivets 7. To assist the fingers 3 to perform their function I provide a yieldable alining plate 8 which is fitted to the contour of the fingers 3,` the said plate being secured at 9 to certain of said fingers, the ends 10 of the said plate being unsecured and adapted to slide upon the plate 1.

The supplemental bracing device referred to consists of a coil spring 11 (Figs. 1, 2 and 3) interposed between the alining-plate 8 and base plate 1 in such manner as to be compressed when weight is imposed thereon. The spring 11 may be secured to the alining plate by a rivet 12 at one end thereof, the lower end thereof resting unsecured in contact with the plate 1. As the alining plate 8 rises and falls during the ambulatory movement of the wearer, the spring l1 will be compressed and extend longitudinally thereof. A spring of this formation is far more durable, for the purposes of its present use, than a flat leaf-spring, besides being adapted to yieldably support the alining plate 8. Furthermore, a coil-spring will recover or rebound, after shock, much more quickly and with more snap than a leaf-spring; hence, the kneading or massaging effect desired is more thoroughly accomplished.

Having now described my invention, what I desire to secure by Letters Patent is: I

l. In an arch-support, the combination of a base-plate and a series of arch-supporting fingers, with an alining plate arrange transversely to said fingers and attached t-hereto also curved above said plate and a coiled supporting spring interposed between said base-plate and said alining plate and consisting of a series of superposed convolutions, the uppermost convolutlon being attached to said alining plate, in order that the swinging of said spring may be prevented.

2. In an arch-support, the combination of a base-plate and a series of arch-supporting fingers, with an alining-plate arranged transversely to said ngers and attached Sig-ned at New York city, N. Y., this 19 thereto, also curved above said base plate daypf Jl1'1y,196.

and a spiral supporting spring interposed between said base-plate and said alinn LEON LOBEL' plate and attached at its upper endtoV t 'e Wftnessesr latter in order that the sW1nging.o.Sad MAURICE BLOCK, spring may be prevented. l EDWARD A. JARvIs.
