To cit-ZZ whom, t may cofwrnfnj 'I Be it known that I, PAUL A. I-IABERL, a

:citizen of the United Statesiof America, re-

siding at Denver, in the county of Arapahoe and 'State of Colorado, have invented a certain new and useful Improved Artificial Foot;

andi do declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompany'- ing drawings, and to the figures of reference vmarked thereon, which form a part of this specification. Y

'My invention relates to an improved arti- 'iieial foot, and my object is to provide a de'- vice of this class which shall be simple-in construction, economical in cost, reliable, durable, and efficient in use.

` To these ends the invention'consi'sts of the features hereinafterldescribed and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated anfeinbodiment thereof.

In the drawings, Figure lis avertical longi- -4tudinal section taken through my improved artiiicial foot. Fig. 2 is an underneath view of the foot, the hinged movable Parts being exposed. Fig. 3 is a sectiontaken on thel line :t w, Fig.' 2.

. Similarreference-characters indicating coi'- responding parts iii-these views, let the numeral 5 designate the framework or body of the foot, preferably composed of some suitable wood. This frame is provided with a central depending projection 5 and is trans- .recess and adapted to receive a tenon 8F',

forme(L en the rear extremity of the toe-piece 5o .8.v The part 6* of the heel-piece'is centrally recessed to receive the rear extremity of the.

tenon Si The part G is provided with vacenj tral aperture registering with an aperture in therear extremity of the tenen 8.`

The heel and toe pieces are connected by Adrawn tightly over thelentire foot., Hencev there is little or no liability for the. sponge rubber to become disarranged or displaced.' f'.

tering apertures. A

Between the heel and toe pieces andthe body part 5 are placed layers 11 and 10,*re-1. spectively, of sponge-rubber or some other?. suitable yielding-or elastic material.

ofthe latter is placed sponge-rubber'lZ or f other suitable, similar, or desirable material.

The sponge-rubber may be'secured in place in any suitable manner, as by gluing .it t'o the ,'gz 'adjacent parts. i

A rubber sheath v(not shown) should bef-I 'lhe

parts

6 and 8. being hinged together,

' and reinforced by the elastic material, allow the artificial foot, asy nearly as may be, allthe y movements of a natural member, thus afford.` 75;

ing the wearer the greatest possible'congifort.V L'

. The foot may be fastened to the stump in any suitable manner. It may also be'fastenedto any construction of artificial limb.'l`

Having thus described my invention, what 8o 1. An articial foot comprising the body part andthe independent heel and toe pieces movably attached to the bod-y part and .rein-v forced by some yielding substance placed between the said pieces and the body part substantially as described. "i

2. An artificial foot comprising the body v part and the independent heel and toe parts movably attached to the body part, an'd reinforced by independent yielding substances placed both abov'e and below the said Inovable part substantially as described.

3. Inan 'artificial foot the combination-of the body part and the independent heelan'd-4 95 toe pieces movably hinged to the4 body part at a common point substantially as'described. Il. In an artificial foot the combination of the body part having a. depending central p'art 5, and the parts`6' and 8 hinged to the body part in such a manner as to bee'apable of movement independently of each other and:
