To allfwliomitmayc0iwe1"lif' Be it known that I DE ROY AUSTIN, a citizen of the United tates, and a resident of Omaha, in the county of D011 las .and

State of Nebraska, vhave invente ,cert-ain new and useful Improvements in Insoles for Shoes, of which the following is a speci- 1 lication. ,y

My invention relates to insolesforboots and shoes, and itis the object thereof-to provide in a boot or shoe an-insole ofrela'f tively heavy material having transverse reduced portions 'by which the same is rendered flexible, and having sai-d 'trans--v verse reduced Aportions reinforced byffresili-l enty material so that the insole will not *be weakened and alsoto that the soles thereof be madeliexible so as to bend easily and permit a natural move ment of the foot. in 'walking 'Suche' ilexibility is` ordinarily attained Iby the 'use of thin soles and insoles,` but the use of thin material, especially for insoles, isobjectionablefor the reason'that at the edges of the sole where it is attached to 'the upper and welt there is insufficient material to give the necessary strength. As a result the insole thus lacking indurability. lIt is also de-I sirablein shoes having cushioned insoles that the cushioning material be so held inl position as to overcome any tendency there- 1 of to bunch orlump, thereby becoming thinner at the points which receive the greatest pressure and thicker at those parts which receive lighter ressures. l

My invention provi es a means for attain ing the above desired results. 1

In the accompanying drawings, Figure 1' is a partial' longitudinal vertical section the sole, so that at the edges ofthe s'ole through a shoe having an insole constructed in accordance with `my invention, Fig. 2 4is a transverse vertical section ofthe same on the plane of the line. of Fig. 1, and Fi 3 is a bottom. plan of the insole and we t with the outsole-removed therefrom.

2 Vand the outsole 3 are all o dinarily used for shoes constructed fordurability and without regard 'for flexibility of provide a resilient or Speeitcaton of Letters Patent. Pattd Jan, 1l),` 1911;' Application filed September 1909; Serial No.

wherethe same are secured-,to the.welt and upperthere isample material to makea strongand durablevseam. :In the front part of the insole, or `fromthe instep to the toe, a number of .transverse channelsI o r grooves are made in the lower side thereof, the. said channels being of uniform depth and the width thereof beingsolnewhat greater than. that of theA transverse-tongues or ribsl 'of The said strips of material are rect-angular in 4 section'and the normal thickness-thereofis'- madegreaterthan theqdepth ofthe trans verse channels so that when the material is vcompressed itl will as nearly asv possible 'just. lill' the channels and the lower surface there-y form to the outline of the`sole,as shownin `,The ends ofy the strip's 4'are shapedto con i gFig. 3, the said strips andthe channels terf'- ',minatinginside the feather 7 vthrough which the insole is sewed to the upper andA welt.`

Between lthe insole and outsole a thinsheet .8 of felt orI other suitable l'material maybe i' f placed, 'and when such sheet i'sused' the vsame is ,preferably cemented in place.'y soon givesway at the edges and the shoe is It willbe'obvious that by the construction" shown a shoe may be provided with a heavy i and durable insole which may be readily..

flexed or bent Vto accommodate the natural bending movement of the foot in walking. The sole rat the thinnedv or weakened portions thereof made by the transversefchannels -is sustained by the stripsf ofresilient der the points ofgreatest pressure so as to conform to'the shape of, the' foot and provide, a cushioned or resilient tread,and that the strips of resilient materialare 4so heldin that Athe same cannotL be displaced' or the cushioning material become unevenlyf dls-v tributed as is liable in cushioned soles wherev material is not so held to its' the cushioning proper position.

"Now, having described my invention,what

I claim and desire to secure by Letters Patent is:
