' Applicant is Aaware that there are various devices on the market for the purpose of relieving shocks to the Mfoot-and particularly "35 the heel. The ordinary rubber heelis Well known however, the rubber heel has its greatest utility when new, which greatly decreases with wear and other causes until the rubber heel isworn out. In applicants device the "40 samev degree of resiliency is', v maintained throughout regardless of the amount of wearv sustained by the heel. Furthermore, devices have been produced for similar purposesv in which the resilient members are placedwithl i4- in the heel proper, the heel having collapsible sides, unsightly in'appearance and requiring in most instances aspecially constructed shoe f for their adaptation thereto. Applicantsdei vice maybe incorporated into anyrstyle of i 59" boot or shoe, either lfancy', dress or work boots l novel.V construction,arrangement? and combination ofparts herein shown and"described,

This is to allow for a Vslight relative motion between the base 7 and the inner sole 3. p

In adapting applicants device tothe ordinary shoe, it is merely necessary to form the depression 6 in the heel portion thereof a proper depth, inserting the appliance and the shoe is ready to be worn. Shoes, however, may be constructed with the depression already formed in the heel portion thereof. For shoes with narrow heels, s'uch as ladies shoes for instance, the depression 6 is of relatively smaller diameter and the size of the spring '11 selected tosuit the wearer. In

shoes with wider heels such asmens shoes,

the depression 6 is of relatively larger diameter and the size of spring 11 is selected accordingly. The term size above referred to is used in the sense of the amount of force required to compress the spring a desired distance.- For instance, a larger size would re-` quire a greater amount of force. Y

It is not intended that the entire weight thrust upon the heel shall be borne by the spring 11. The spring 11 is Vmerely intended for the purpose Vof relieving the shock, the downward movementv of base 7 being brought to rest by the under surface 12 thereof coming in contact withV the surface 13 of the inner sole 3. The proper size of spring 11 will be left somewhat to the choice of the wearer of the shoe. However, should thewearer of theV shoe desire to have the heel of the foot entirely supported bythe spring, it is only necessary to insert a larger size l(or stronger) spring, or the spring already in use may be stretched if of relatively large size.

Itis obvious that applicants appliance'may be worn with shoes either with or without rubber heels. There is no necessityfor a rubber heel; however, shouldV the wearer choose to have same applied, same will not i interfere in any way withthe operation of This device is of particuL lar utility in large work shoes and boots, particularly hob-nail boots and shoes and those having steel plates applied to the under surface thereof. Y e

In. Fig. 4 is shown a modificationpreferi able when rubber heels are attached. A plate 14Vof metal or other suitable material is placed between the upper portion of the heel 4 and the attached rubber lheel, 15. Spring 11 rests on plate 14. 4, 14 and 15 are secured together by any suitable means, which may be by the usual nails used to attach rubber heels. Y v

In' Fig. 5 plate 14 is inserted ina recess 16 formed in the heel 4. In the latter form the plate is not exposed to View or the elements, and is often preferable. f

Furthermore, the relative movement between the innersole 3 and the base 7 need not be very great to obtain the desired degree of resiliency. In fact the spring need not be compressed any morethan the ordinary rubber Vheel is compressed to obtain the same degree of shock absorbing qualities.

It is readily ,seen that after the pair of yshoes is worn out, the device may be removed therefrom and placed in the next pair of shoes. To restore lost resiliency it is only necessary to Vslightly stretch the spring.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without, departing from the spirit of my invention;

vhence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and. combination of parts herein shown and described, or uses mentioned.

What I claim as new and desire to secure by Letters Patent is 1. In combination, a shoe, a depression in the inner bottom portion thereof at the heel, a resilient member insaid depression and forming frictional Contact `with the sides of the latter, and a base portion above the depressionindependent ofthe innersole of the shoe, said baseportiolv `clamped and supported by said resilient member. I j

2. In combination, a shoe, a depression in the lioor thereof at the rear, said depression extending through the floor of the shoe int-o the heel ofthe shoe, a resilient member within and guided by said depression, a base por= tion above the depression adapted to contact theheel of the foot, said base portion clamped and resiliently supported by said resilient member, said base portion resting upon the innersole when the downward force thereon is greater than the upward force .of there silient member. f

In testimony whereof, I have hereunto signed my name. l
