ARCH-SUPPORT.

To all whom it may concern:

Be it known that I, ROBERT E. BELGHER,

Specification of Letters Patent. Application filed February 11, 1914. Serial No. 817,989.

a citizen of the United States, and a resi dent of Chicago, in the county of Cook and :State of Illinois, have invented certain new and useful Improvements in Arch-Supports, of which the following is a specification.

My invention relates to arch supports and contemplates improved features of construction, arrangement and adjustability.

My invention is particularly concerned with arch supports in which metallic spring plates are superposed. In prior devices of this class the superposed spring plates are free to give and flex under the wearers I Patented Mar. 16,1915.

' they may be readily individually bent and weight but no provision is made to limit such flexure, the result being that the plates are bent beyond their elastic limit and will eventually flatten so that the arch support becomes inefi'ective for the purpose for which it was intended. It is also very desirable that the wearer himself may be able to adjust the arch supports,-that is, to make adjustment to increase or decrease the height of the arch. For example where a person with a broken arch decides to wear arch supports, such supports should at the beginning be low and comparatively fiat so as not to immediately raise the foot arches into normal position. Gradually, however, the height of the arch support should beincreased so as tobring the foot arch gradually to normal. adjustment could not be readily eflected by the wearer himself but special mechanical devices or machines were necessary. It is, however, very desirable that the wearer himself may be able to effect such adjustment order that he may obtain the greatest amount of comfort and good from the supports. I

One of the important objects of my invention is to provide spring plates which are free to flex under the wearers weight and movements but whose flexure and relative movement is limited in order that the In prior structures such adjusted, and Fig. 4 shows a modified arrangement for interlocking the plates. f

The arch support comprises the metallic top or arch plate 1, the lower metallic supplemental plate 2, and the leather cover 3 forming an insole. The top or arch plate 1 has one lateral edge 4 curved or curled upwardly to fit the inside curve of the foot instep, as is well understood. The insole .3 is preferably secured to this arch plate as by means of rivets 5 and 6, and the corresponding side 3 of the insole is extended and follows the upward curve 4 'of the arch plate as is well understood;

The supplemental plate 2 is riveted at one end to the corresponding end of the arch plate in order that such-plate 2 may swing about its pivot with relation to the arch plate. As shown, the rivet 7 pivots the front ends of the plates together and the arch plate so that the arch plate rests only at its ends on the supplemental plate. The

plates are stamped from metal which is elastic within certain limits and which can readily be bent by hand, as for example German silver. By 'virtue of the pivot connec tion 7 the supplemental plate 2 can be "swung into position at substantially-right elastic limit is never reached, the plates berangement that the plates can readily be bent by hand by the wearer himself in order to raise and lower the support arch asdesired.

angles with the arch plate (Fig. 3) to thus leave both plates free to bereadily individually bent to vary the degree of bow thereof and therefore to adjust for the height of the arch support. 1

Describing now the means for yieldinglyi locking the plates together after bending and adjustment thereof, the arch plate has extending downwardly therefrom one or more ins 8, 8, the supplemental plate -.;supplemental plate will act as a tie or chord pins reach has one orniore holes or openings 959" and 9", 9' ferthezpinsrespectively.

When ad ustingthe plates 'thesupplemental plate" should preferably- ,be unbowed suifi clentl'y in order thatwhen the plate isswung to plosed position the inner edges eof the guide slots will abut against the respective pins, under the heads thereof and in order thatthe plates will be locked against. pivotal displacement by the engagement of the inner ends ,or pockets f'j'ef the longitudinal-slots to with the pins, When the supplementalplate is brought tonormal position thepins will snap into the inner'ends 7 of the pocketsand accidental displacement of the plates will-be prevented, although the separation. thereof can be readily accomplished by slight pull on the'supplementalplate. In order that a better hold maybe obtained ,onthe supplemental'plate a hole 12 -i s provided in its end the setting in Fig. 2 the heel end of the arch platecan move relative to the supplemental plate until the outer ends g of the .slots 9 and 9, reach the pins, and thereafter the to prevent further longitudinal movement andflattening of the arch plate. 'It w1ll be noted that the slots 9 and 9 arelonger than the slots 9 and 9" This is for the. purpose of allowing for greater relative longitudinal movement of the plates if such 1s- "desired. If such greater movement is desi'red', the supplemental plate ,1 is swung farthen until the longer slots receive the pins. The longestslot is, however, not long enougli to allow flattening of the arch plate beyond its elastic limit so that after each depression or flattening of the arch plate, as during. walking of the wearer, the plate w ll return, the pins playing back-\and forth in the longitudinal slots of the supplemental plate and the supplemental plate preventing further flattening of the arch as'soon as the the outer ends of these 'I thus the arch plate to face for the ends of thearch plate and said supplemental plate'being also bowed but to In Fig. 4'pins 8, 8 are not headed and i have omitted entrance ways to the slots in thesupplemental plate. With this zurangemen't after the "plates" have been swung apart and adjusted the supplemental plate is swung back tonormal across the tops of the pins-.andthen under slight pressure. against the .center of the supplemental plate the end'of the plate will be drawn in f to bring the slots-.irliiregister withv the pins and. the pins will thenbeat the inner ends of the slots, and whenEthe support is .in use the pinsfwill trau'elforth in the slots in the same-' i mannieiifas in the arrange ment of Fig; .2.

There is therefore nothing requiring special skill in the adjustment of the support and such adjustment can be accomr'id. operate and plished by the wearerr himself1veryreadily and perhaps with greatersatisfaction than if performed-bysomeone else.

I do not desire to be .limitedfto the exact construction and arrangement shown as modifications could no doubt be made which would still come within the scopeof the invention.
