This invention relates to improvements in calked soles vand aims primarily to provide a calked sole thatis capable of ready adjustment to various sizes and types of boots or '5 shoes, that is especially designed for rapid attachment thereto and similar removal therefrom, that is particularly adaptable for use by fishermen, hunters, loggers,.mountaineers, shinglers, and the like, and that will not become clogged whilein use. Y

Contemplated by the present invention is a self-cleaning iexible calked sole embodying a vcalked sole section, a shank section hingedly connected to said sole section, a heel section.,

longitudinally adjustable upon said shank section, laterally adjustable means for securing the sole section tothe .shoe or boot of the wearer, means for securing the heel section to such shoe .or boot, and a series lof integral calks of novel form Vdisposed in spaced relation upon the perimeters of the sole and heel sections, all of which are -importantobjects of the invention and are to be correlated in the broad aim of enhancing the efficiency -of thevdev'ice for general use. j

rEhe above, and additionalV objects which will hereinafter be more `specifically treated, are attained .by such means Vas are shown in the accompanying drawings, described'in the following specification and then more clearly pointed outin the claims, which are appended hereto, andV form a part of this application.

With referencejtothe drawings in which there is illustrated one embodiment of the invention, and throughout the several views .of which like Characters of reference designate similar parts.

cated in accordance with the present inven- -752 tion and comprising a sole or forward section 17, to the rear end. of which is hinge'dly connected, as at18, a central or intermediate'section 19 having a relatively narrow rearwardly l extending integral tongue .20, to which is adso Y justably secured a forwardly eXtendingintegral shank 21 of a downwardly voffset heel or rear section 22 having `the material at its rear end bent upwardly to form a heel retaining portion 23. j Y j v 85 The sections 17, 19 and 22are fabricated., from sheet steel, or the like, 'anddisposed in spa-ced relation upon the perimeter .ofthe sole section 1-7 and similarly upon the perimeter `of the heel section 22 is a series of tri 90 angular corrugated calks 24, which arejstruckl from the material of said sections and bent downwardly from theedges thereofsubstantially atright anglesthereto, the apeXes of .f

said triangular calks constituting sharpened j gripping points." During the dielstamping 'j I or forming of the calks 24,the same-are flexed f to provide corrugations25 therein, whichlatter are formed in parallel relation to the axes of the ca-lks, as lshown more clearly `1M.

Fig. 11 vis avertical transverse section lo5 Y Figs. and 12, this for theV purpose of reinforcing such calks andfor providing a par-V ticularly rugged type of calk capable of considerable resistance against termediate vsection '19V is a central row of transversely disposed calks-26, which are also ofA triangular and' corrugated formation. By forming the calks 24 upon. the respective perimeters of the sectionsl 17 and 22 in they mannerherein Vshown andl described, it will Vbe observed that such calks are longitudinally disposedin substantially parallel relation to the axes, of. their correlated"sections,-thus permitting of any bending action or stress u p`on1the calks being applied longitudinally Y 1y prevent llodgen'ient of any foreign mat thereof [and notv transversely, whereby any tendency of such calks to bend duringV rough v`usage is effectively minimized, for the reason that the load is imposed thereon in an edgewise'or sidewise direction, vand 4due to the rerangement 'the present calked sole is self- ,cleaningy inasmuch vas there is sufficient open `space Aand ilatfsurfaces'between the rows of calks, so that yany foreign matter or dirt is `ejected and cannot become clogged between thecalks.'

."Detachably secured," as by a screw 27, to

. the forward end of the Vsole section A17 'is a toe cap or protective member 28, adapted to normally abut the toe ofthe e-15, when the calked sole is in use, whereat'such member functions to effectually prevent debris from finding lodgement between the forward end V,of the cal'kedv sole andthe sole of the shoe.

The sole ysection 17 lis provided substantial- `Yl midwa the lenf'rth thereof Ywith a laterali 1 y y e d vdisposed downwardly offset channel or giuldeY 29', the bottom wall of said channel adjacent `its ends and at each side thereof having lugsy 30 struck therefrom,'which latter are retained 'in the plane of the sole section 17; Slidably interposed between the channel 29 and the' lugs 30 are Aangularly `formed' sole Vvretaining members or keepers 31, the upwardly bent Vouter ends of which are adapted to n normally 'abut` the sides of the sole o f the shoe 1 5, to thereby prevent si'd'ewise or lati Yeral dislodgement ofthe sole section there- V 1 on, Formed and provided within v.each inner terminal portion of the sole retaining'members 31 are' slots 32 havinga series of opposed of the rchannel 29Vare screws` gli, whi'c notches cut in the sides thereof. Selectivelyinsertible lwithin the notchcsr and threadedlyengaged within the bottom wall serve'and functionto lsecure the sole retaining members 31` in predetermined y distortion; VStruck from the sole section 17 and the inlaterally adjusted positions,vwithin and relative to the sole section 17, which positions are deter- :I mined bv and regulated in accordance with Y the `width of the shoe to which the calked sole is applied. It will be apparent and obvious from the foregoing and by reference tothe drawings that vertical dislodgement or displacement of the sole retaining members 31 from the channel 29 is eifectually prevented by the lugs'SO, which function to vmaintain such members within said channel.

The sole section 17 is adjustably secured to the vamp portion ofthe shoe 15 by' a sec- :tional strap 35 havingV its outer terminals riveted to thevouter ends of the sole retaining members 31 and having itsopposing inner terminals adjustably connected vby a frictional buckle 36. 1

- The tongue 20` of the intermediate section' 19 is provided withja longitudinallyv disposed l' central slot 37 Yhaving aseries of opposed notches 38 cut in the sides thereof, said tongue s being also slidably interposed for longitudi-l nal adjustment between the shank 21 of the heel section 22 and a transverselydisposed stripY 39 of relatively light dexible material, thefterminal portions of which are `flexed downwardly Vto pass through longitudinally disposed slots 40 formed within the edge poritions of the'shank 21 andare return bent ther-eat to provide upwardly extending apertured terminals All. Tosecure the tongue 20 in a predetermined longitudinally adjusted position upon the sha-nk 21, a screw 42 is provided, which eXtendsthrough Ythe strip39r and the selected notches ,38 of the tongue'20 and atits lower end is threadedly engaged within. the shank 21. Straps 42 provided with elongated ring members 48 at their'forward looped ends have Atheir forward terminal portions slidably disposed within .the apertured terminals 1l andV alsor within the members 43 and at their rear looped ends'are engagedwithin vangularly disposed slots 44 formed within the vheel retaining portion 23.

A sectionalstrap 45 having its outervlooped ends engagedwithin the Aring members i3 and having its opposing inner terminals adjustably connected by a frictional buckle 46 is provided to adjustably secure the shank 2l and heel section 22 to the heel or rear portion of the shoe 15. It will be notedlby referring to the drawings, that by employing the type of straps herein shown and described,that such straps readily conform and automatically adjust themselves to the contour ofthe heel or A,rear portion ofthe shoe 1,5 irrespective of the size or'type thereoiwhile also fur.- iishing a rapidand efficient means for ad- Viustal' lv secr-.rinfr Ytheheel section 22to the f i s v v shoe v15.

In attaching the flexible calked 'sole` l'to 'he hoe 15, the tongue20 is longitudinally adjusted'upon the shank 21 to vaccommodate such shoe, the retainingvmembers 31 are then laterally adjusted for the same reason, where- Y upon the calked sole is ready for attaching to the shoe, which latter is effected byadjustably securing the straps 35 and 45 with their respective buckles ,36 and 46 in an obvious manner.

Manifestly, therefore, the calked sole of the present invention is extremely simple, durable and economical in construction, is efficient and reliable in use, possesses the requisiteflexibility to assure of ease and comfort in walking, will not cramp the shoe or foot of the wearer, will effectually prevent slipping upon ioy or other slippery surfaces, and will not mar or injure the shoes or boots when positioned thereon. l While I have herein shown and described my invention with suflicient detail to enable those skilled in the art to understand the mode of construction and the principles involved, it is to be understood that there is no intentional limitation herein to the specific form and precise details of construction of the invention shown and described except as expressly defined by the appended claims, and that various modifications of said construction may be resorted to without departing from the invention, or the benefits derivai ble therefrom. I also desire'to have it un- 1. rlhe combination in a calked sole for a shoe,` of a triangular corrugated calk struck from the material of said sole and bent downwardlyrat right angles thereto.

2. The combination in a calked sole for a shoe, of a triangular oalk struck from the material of said sole and bent downwardly at right angles thereto, said calk having a series of corrugations formed thereon substantially in the direction of the length of same.

3. The combination in a calked sole for a shoe, of a triangular calk struck from the material of said sole and bent downwardly vat right angles thereto, said calk having a series of corrugations formed thereon in parallel relation to its axis.

4. The combination in a calked sole, of a heel section having a forwardly extending shank portion provided adjacent its side edges with longitudinally disposed slots, a

and return bent to provide upwardly extending apertured terminals adapted tol receive means for securing said heel section to thel shoe.

In testimony whereof I afiix my signature.

HORATIO A. SMITH.
