This invention rename inner soles for shoes, and one of .theobjecfts of the invention 'isto provide an innerysole' which is rein forced by wirelgauze'disposed between layers 7 of fabric, the wire gauze reinforcing member being so cut that the Wires are on a bias with relationto the lengthof the sole, thus acting to prevent the wire gauzefrom bending in a line at right anglesto the longitu- Q10 dinal wires and thus breakingior wrinkling.

A further object is'to so, construct this reinforcing member that there will be no projecting wires at the margin of the reinforcingmember and to provide a reinforcing 51 5 member of which the body is formed of copper wire while the margin of the "reinforcing member is coated with zinc or like metal so i as to form an electrical element.

Afifurtherobject-is to provide an inner sole 2 0 I which is extremely flexible and which will ex- ,ert no friction on the'foot and will not, there- I fore, tendto cause'undueheatr A further object is to provide an inner sole 7 which will give warmth to the foot by having 25 the upper surface of the inner sole formed of wool while-'the 'lower surface is formed of cotton or like material and which inner sole Another ob'ect is to provide an inner sole .30 with an extension which will extend beneath the great toe and have sufficient flexibility to permit the great toe toiflex without trouble and to, provide means whereby this projecting portion of the inner sole may be trimmed to 3,5 suittheshape of thefoot. I Other obj ectswill appear in the course of e 1 a thefollowingdescription. I

' My invention is illustrated inthe 'accom panying drawings, wherein I 1 F'gure 1 is a plan view of an inner sole constructed in accordance with my inven-' Fi gureQ is a plan view of the reinforcing element for the sole;

V the toe portion thereof;

tudinally of the "sole and extending through Referring to these. drawings; itwill be seen i that the inner sole comprises a lowermost c c importantfeature. f may be readily washed at any tlme,

I 'Figure'Bis a fragmentary section'longi- I ordinary bed ticking, a second layer of cheese "cloth or like material 11, a reinforcing la yer of wire mesh 12, and an uppermost layer con-' 'sisting preferably of twothicknesses of wool fabric,-these thicknesses being both'desig nated 13. The several layers are stitchedtogether around the margin of the innersole.

,- The wire layer 12 does not extend the fulllength of the sole but terminates short thereof on the line 14: so that thelayers oftextile 'fabric project beyond this portion to form r 5 what might be termed a flap 15. This flap is formed with linesof stitches 16 approximately concentric to the rounded end of the, I

reinforcing layer 12; This permits the flap 15 to be trimmed downIto suit anyparti'cular shoe or foot.

--A will be seen from igure 2, the wire mesh reinforcement .12 has its transverse wires extending diagonally to thelength' of the 's'oleafnd its longitudinal wires also extending diagonally to the length of the sole F or atright angles to the transverse wires. 1 Thus the individual wires of the Wire mesh are disposed on'the bias with relation to'the" regard as a very length of the isole'f'This I Furthermore; it will be noted that margin of this reinforcing layer 12 of wire mesh Q is coated with zinc or solder 17- which con- I stitutes what may be termeda binding'for 1 this wire mesh. These two featuresI rei gardas" important for-the following reasons. i .7 I have found by" actual test that it is impract I fticalto have the wires extending longitudie 'nally of and transverselygacross the sole as thelengthwise strandsof the wire mesh b'egin tobreak first in the center of the shank of the sole and their following the Wire cross strands across the sole. Furthermore Ihave found where the cross stra'ndsextend *at right angles to the length of the sole that these cross strands vwould creep out through the edge of the sole regardless 'of'how well it was stitchedgor sewed or whetherit was bound with cheavycloth at the edge. After a the lengthwise strands of wire have'broken across the sole and the transverse wires begin to creep out at the edge, "the solebe-j 00111981300 uncomfortable for wear. I have found that by cutting the Wire on the bias and coating and covering the outer edge with solder, zinc or like material as by'dippingsufliciently to entirely embed the outer edge or marginof the wirenetting with the solder T or zinc, the transverse strands are prevented from creeping out at the edges and furthermore-thisconstruction permits me to securely sew the reinforcing layer 12 in and to the covering of the sole. Relatively long usefhas shown that with such a cons'tructiofn'nas.1 have above described, there are no brolren strands of wire, nor do the wire creep out at the ends, 7. p v 1 The wire mesh being'cut on the bias makes ithe inner sole extremely fiexible. Paper,

. cork or composition inner. soles also tend to unduly .heat the foot. By-havingi wool on top of the inner sole, Warmth is given to the foot withoutundulyheating it While the cot-,

jfton absorbs mo-i sture from the foot. The cold air coming up from the bottom and the.

heat coming from "the foot meet .in the air chamber which is formed injthe interstices of the wire and any condensed moisture is ab- .sorbedby the. cotton-fabric as are also any impurities comingfrom the feet and from thesoles of the sho'es. v This inner sole can 0: be washed and kept clean from all impurities can bescru'bbed in such a manner as to ;remove. ;grease, dirt and filth that may come from orking in shops, etc. The more thisinner sole i -s'washed, the softerathe fabric becomes. Inner, soles that cannot b washed become unsanitary, f

Furthermore the use of zinc as a binding for the copper wire mesh: on coming inlcontact with the moisture of the feet tends to secure a slight electric current andstop any corrosion of the'copper, Ifurthermore find i L that this combinatienjof the copper and zinc rows of stitching extending across it per mitting the flap to be trimmedto fit the foot. 2.
