To alii/17mm t may concern:

Be it known that l, linnncis Nonni, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful improvement in Shoe-Soles, of which the following is a specification.

This invention relates to certain new and useful improvements in ruhher soies for boots, shoes or other foot wear, and more particularly relates to a new article of manufacture which is especially designed for permanent attachment to such foot wear in a ready and eiicient manner at the expendr ture of less manual effort and without sacrificing strength or rigidity at any point throughout its several dimensions.

This invention relates to a new article of manufacture consisting of rubber or other resilient soles to be attached to boots and. shoes or other foot Wear -as distinguished from rubber soles that are vulcanized vto or integral with boots or shoes and attached thereto during the process of inanuacture.

Heretofore soles of the type mentioned, namely rubber soles, have been reduced in thickness or made thinner throughout the entire shank. thereof than the balance oi the sole, that is the tread portion, in order 'to ena'L-le it to be more easily attached and titu ted to the arch; out this particular or1nation has been found objectionable due to lessened support at this point oi the shoe and a consequent increased tendency 'to break or crack.

An object of this invention is to so fashion the shank portion of the'soie 'whereby full strength and rigidity are maintained and at the same time to permit the thorough and easily accomplished littiaiig of the sole, hy the shoemalrer to the il further obi/ett is to mold the sole with an opper surface esp cially designed to aid by natural action the permanent attaclr ment of the sole to theshoe.

A still i i r ohliec't is to provide or iornl the hall porti n oil the soie with improve-.fi anti-skid means; -r-.f erehy tendency of the wearer oit the thus equip shoe to siipin any direction is eliA @ther and further objects and? advantages will be apparent irons. the iollowing description.

ln the drawing,

l gure l is a bottoni plan view ci the sole equipped with the improved anti-slipping means;

Fig. 2 is a section taken on the line orn Fig. l;

Fig.- 3 is a section taken on theline Y-Y of l;

Fig. i is a section taken on the line W-V of Fig. l;

Fing. 5 is a section taken on the line Z-Z of F ig. l;

Fig. 6 is a bottoni plan view of a inod-iied forni oi' sole showing a slightly diferent pattern of anti-slipping means employed;

Fig. 7 is a longitudinal*section taken on the line lie-R of' Fig. G; and

F ig. 8 is a transverse section taken on the line S-S of Fig. 6.

Lilie numerals of reference refer to like parts in the several figures of the drawing. ln the drawing, the reference character A, see Fig. l, represents the fore part, B the shanlnand C the heel seat of the sole which, as 'will be understood, is adapted for attach-- nient in any desired manner, to either the shoe insole or to the upper thereof. ln the sectional views ci this figure, the entire upper surface of the sole is illustrated as being suitably dished or otherwise provided with a continuousconcave face l0, designed to contact evenly thereabout with the inner sole or lowersurface of the slice, thus retaining the rubber sole in the desired and Athm-oughly effective position during the cenienting action while the sole is being attached to the shoe as well as thereafter. The preferred .manner of constructing the soie is to provide the sanne with a flat or substantially flat base portion l2 of suitable thickness and of a shape generally conforming to that of the inner sole or shoe upper to 'which it is vto he attached but on a somewhat reduced scale; while extending conipletely around the edges of such hase porti nii), is a i3 in the nature of a bevel or appronnnateiy equal thickness with that of the hase. lli/'hen a rubber sole of the type filescrihed attached to the shoe, a resulting natural 'suction and clii'sging tendency is eiiected which cooperates with the artilicial means employed to vfasten the rubber sole in proper position. Furthermore, the iange or beve-i portion is of such nature as enables one to trim the same should there he a porness throughout and terminates at' its rearjextreinity in the shank B, the central portion le of which is of equal thickness with the fore part A from whenceit is charnfered od along its longitudinal edges and at its rear extremity as shown at'l and 16, respec- I tively, t0 form side portions 17 'and the heel seating portion C of less thickness than the tread and the central shank portion. ln this way, a rubber' Whole sole is provided, the shank of which is materially reinforced in strength and which still permits of the easy shaping thereof to the shoe.

In Figs. 6, 7 and 8, is shown a slightly inodiiied construction of sole with more especial reference to the-shank thereof. As in the preferred form, the entire upper shoe contacting surface yof the modification is concaved throughout; while at that portion of the sole corresponding to or constituting the shank ot' the sole, the upper surface of the device is further cupped as shown 'at 18 to form a weakened portion extending centrally and longitudinally of the shank throughout the length thereof, the portions 19 of the shank to either side of the cupped portion 18 being` of equal thickness with the tread of the sole and terminating et their rear .extremities in a heel seat or in a built up integral heel 20 as shown in Fig. 7.

"When molding this forni of sole, it will be understoodthe heel thereof may be equipped l with suitable nail retaining devices such as Lin the washers 21. By this construction, a de- -g'ee of rigidity and strength is afforded at the shank which is not present in rubber soles now on the market and at the saine time the centrally weakened portion permits the flexing 'of the shank to render it easier 'oi' attachment to the shoe.

In its completed form, the fore part of the sole is also provided on its exposed lower surface with a plurality of especially shaped and arranged corrugations whereby tendency of the wearer 'to slip in any direction is obviated. Figs. l and 6 show two pat- "terns of the improved anti-skid inea-ns which have been found to be most practical for the purposes. ln both of these views, the corruu gations, which are illustrated as being rounded 'on their outermost extremities, are spaced at parallel intervals and extend to each side of a 'common line, represented by the nup Vor adjacent their rear ends rwherethe greatest pressure is normally brought to bear. By this particular arrangement,'it will be sppreciated that the possibility ci slipping in any direction isffrninimined.

ln accordance with the'petentstatutes, l have described the principles of operation of my invention, together `with the sole which l new consider to represent the bestembodiment thereof, but .i desire to have it' understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claimsB niff-laying described my invention, what l claim as new` and desire to protect by Letters Patent is:

l. A resilient shoe sole having a body formed with a fore part and shank, the fore part and a portion of said shank extending .from the fore-part to the heel line being of even thickness and the" remainingportion of said shank being` oi less thickness, the

thickv portion. of saidshnnlt being beveled into said thinner portion.v l

2. A resilient sole to be attached. to footwear heving a body formed with a flat upper surface land with a fore part, shank and heel, the heel and fore part being of dierent thickness andthe shank having one portion cfnrrespending,- in thickness with thel
