My invention relates to a novel shoe construe-,-

tion and more particularly my, inventionrelates to a shoe outsole formed of'wood. or an equivalent substantially rigid material, constructedso that the necessary flexibility for the foot; is pro- ,5.

It is a further object of the present invention to provide a shoe outsole that, from a utilitarian standpoint is capable of substantially replacing leather. V

It is a further object of the present invention to provide a flexible wooden outsole.

It is a further object" ofthe present invention to provide a novel shoe OlljtSOlBil'l which LRIZQ- vide proper transverse flexibility without; allewingsuch play or looseness as would interfere with the proper use and wear of the shoe.

These objects, 1'; accomplish by so jointing a Wooden shoe outsole that the, outsole, bends at various points along its length but the joints by which this bending is accomplished, are so interlooked that while'there-is a small amount of rotary'w' movement, this rotary movement, is restricted andflimited.

I have also. formed the entire shoe outsole, heel and arch, structure of. one; piece oi wood, thereby avoiding the multiplicity of operations and parts hithertoemnloyed In the drawings,

As seen in Figure 4, 32 is a typical projection which extends into a recess 33. This allows but a very limited side movement and keeps the flexible joints in the outsole made up of such joints in a straight line, thus avoiding wear and tear on the element or elements that secure the jointed parts together, which may for example In Figure 6, 1 show a 51 .3 comprisegajabrio or leather cover element secured at the top of the joints in the position of an insole, or this joint element may comprise a.

rubber insert set into the wooden outsole and attached to the various jointed parts thereof.

, Rubber lugs 34 disposed at various locations throughout the outsole provide a. flexibility and softness that is transmitted from the ground to the insole. I I p V Figurefi showsa detailed cross section in which an insole 40 is set'i'nto an outsole generally de noted as 4|, insole 40 being secured to the separate segments of sections 4t, 42, 43, 44 and 45. The insert 40 may be of leather, fabric orrubber and isxfirmly secured byadhesive or the like securing means to the various wooden sections that comprise "the outsole. When the insert is of rubber,it provides a softness and resilience for the foot that plays a great part in making the r I wooden outsole satisfactory for the purposes described. To enhance that softness and cushioning efiect, ;I provide a'multiplicity of-rubberlu'gs 41 which help to' iorm a path through'the non-compressive wood'b'etween the insert and theground.

i For this purpose the lugs 47 extendslightly below the level'ofthe outsole; 1

'milar construction but in-whichthe lugs 48 are set into the outsole and do not extend up into contact with the insole. The proper distribution of these rubber 'orresilisole give the'wooden outsole a desirable softness and yieldability. The rubber lugs 48'do'not contact 'thefinsert 49 which holds the various wooden sectionsqiill but they do improve the property 'withregard to the softness.

In Figure 7, I show a detailed view of. a structure in whichthe interlocking finger and recessed joints such as Hand 53 are; interlocked with a rod e1e'm'ent 54, thisrod extending through the extending fingers-and through the recesses of the interlocking joints s'othat the proper swivel action of the "joints is obtained. 7 g

In Figure 8 Ishow a shoe-comprising anupper 60 and 3111 911135018 comprising anoutsole portion 16 lflforniedof wood which comprises the heel portion '52 andthe'arch portion Eli-and a partof the forepartfl64fi Secured to the portion 6| in any suitable "manner is a leather forepart portion 65.

'In lieu of leather some otherflexible and/or resilient material, such as 'a-plastic mimmay be employed. :Thus, by; the use of the relatively small amount of leather embodied in portion 65,

" I get mos t of the desirable properties of flexibility'and resilience of the le'ath'er'outsole;

In Figure 91 show a'wooden'outsole 10 with *a'n'insert-H disposed-in a recess 12' in said outsole 70. The insert H may comprise leather or rubber or some other resilient material which provides theproper foot comfort. It is desirable when an all-over wood -;outsole is employed, jointed in whatever way is necessary to give flexibility, that foot comfort be providedin the form of asoftand resilient forepart ball portion; I Bythest'ructures shown herein, I providea shoe "having' a f wooden outsole with many unusual properties, more particularly flexibility for-ithe tially rigid material, the upper surface of said outsole being recessed, a resilient insert disposed in said recess, said resilient insert comprising means for securing said joints to one another,

openingsin said outsole extending vertically and completely through said outsole, and resilient em lugs-atisuitable intervals throughout the outp plugs disposed into said openings said resilient plugs being of sufiilcient length and positioned so as to be in direct'contact with the resilient insert at their upper end and to extend to the outer surface of the outsole at their lower or. opposite end. L k r N 2. An'outsole' comprisingjoints of a substantially rigid material, the upper surface of said outsole being recessed, a resilient insert disposed in said recess, said resilient insert comprising means for securing said joints to one another, openings in said outsole extending vertically and completely through said outsole, and resilient plugs disposed into said'openings, said plugs contacting said resilient insert at their upper end and "extending slightly beyond the lower surface of the outsole at'their lower or opposite end. I

V 3. An outsole comprising joints of a substantially rigid material, the upper surface of said outsole being recessed, a resilient insert disposed in said recess, said resilient insert comprising means for securing said joints to one another, openings in said outsole extending vertical ly and completely'through said outsole, and

resilient plugs disposedintosaid openings, said plugs contacting said securing means at their upper end and extending slightly beyondthe lower surface of the outsoleat theirlower or opposite end.
