POROUS BOOT OR SHOE SOLE Filed March 19, 1934 Feb. l11, 1936.

Germany June 23, 1933 e claims. (ci. a6-
This invention'relates to a boot or shoe sole, of rubber or similary material, provided with tread tuds or projections and with holes or perforaions.
According tothe present invention, the perforations or holes are located at the weakest places of the sole material and therefore between the projections ortread studs. Moreover the holes or perforations disposed between the studs 10 are preferably provided in the middle portion of the sole, whilst, ini-the vicinity of the edges, vthe sole is left in an'unperforated condition.
Attempts have 'already been made to provide A holes in smooth rubber soles, that is, soles unprovided With projections or tread studs. These known embodiments, however, are attended lwith the defect that the upper edges of the holes, at the point of ,intersection with the surface of 'the tread, come into direct contact with the dirt or the like so y`that the holes become clogged, and the breathing oi' the soles, attained by means of theperfortions, is rendered` illusory.
' Moreover, in the case of smooth soles, the durability is also lessened as the result of perforation.
'Ihe boot or shoe sole of the present invention fundamentally avoids the defects of the soles hitherto known. The location oi' the perforations or holes between the tread studs, and therefore in the weakest portions of the sole produces an improved effect which should-not be underestimated, namely, that the smallest and weakest surface is available for the attachment and adhesion of the dirt that lodges in the holes. Since,
' in walking, the sole naturally acts on the weakest points, through the pressure on the projections,
the holes, which may have become occupied by dirt, are compressed and re-expanded, thusautomatically dislodging said dirt. 'I'he space 'between the raised studs and. the weaker places, which are 40 situated at a much deeper level and in which the holes are located, enables any dirt that adheres to the soles to dropiout with ease. It is also important that the soles should be so perforated that said perforations are preter- 45.ably located in the'middle portion oi' thesole,
so that the latter is left solid in the vicinitypof Y the edges.
In order more clearly to understand the invention, reference is made to the accompanying drawing whichillustrates diagrammatically and by way oi' example, atypical embodiment of shoesole-according to the invention, and -in which:-
Fig. 1 isa plan of .the sole; and Fig. 2 a section of same.
In said drawinga denotes the leather outer sole, to which the sole b of the present invention 5 is secured, by'cementing, in the known manner. As can be seen from the section, the sole itself is provided with projections or tread studs, between wliich-and therefore at the weakest parts I of the sole material-are located the fbreathing 10 holes c.
`As can be seen from Fig. 1, in order to provide an unperforatedv edge, the holes or perforations do not extend right up to the edge of the sole. @In addition to the advantages hereinbefore de.v 15 scribed, thecementing of the sole is facilitated, inasmuch as, in attaching the sole according to the inventian, any air that is present between the leather-sole and the applied sole can quickly escape at all points, and the formation of bubbles 20 further in is also prevented. Since, in the embodiment according to the invention,'.the flexibility of the sole is increased, it adapts itself to all the irregularities of the ground," and the protrusion of the sole beyond the edge of the shoe 25 is thereby substantially diminished. l l
Having now particularly describedand ascertained the nature of my said invention and in what manner the same is to bev performed, I
declare that what I claim is:- 30
1. A bootJ or shoe soleof rubber or the like material having a plurality of relatively thickr portions defining` a plurality of spaced studs, saidstuds being connected by relatively thin portions of said sole having apertures formed therein and 35 providing a plurality of iiexing elements between s'aid studs4 to change the shape of the apertures when said sole is iiexed. v
2. A boot or shoe sole of rubber or like material having `a plurality of relatively thick por- 40 tions dening spaced rows of studs, said studs being vconnected by relatively thin portions of said sole, said thin portions being provided with apertures in an area less than that of the wholel sole'so that rows of studs and an imperforate 45
