a relatively light. rubber sole capable of being attached by nailing or screw fastening to the leat-her inner 'sole of a 'boot orshoe -at points well inwardly removed ;from the V edges of 'the' two soles;` and at the same time provide that the rubber sole will so co ordinate with the inner sole 'along its edge as to make such tight joint or seal- 'i formngiconnection therewith as will prethus thick and heavy it lacks life bee and cumbersome,` and `can- 'aforesaid' r v vent the entry of water. `The difliculty under such conditions 'of fastenng for' obtaining a tight joint around the edge of 'the inner sole *and between' it and e 'the outer rubber sole resides in the'fact that'thetwo soles are being fastened together at points well inwardly removed from their edges; i If v the rubber sole be made sufliciently and heavy with little body flexibility a' fairly good 'joint may be' obtained under such con-r dtion of fastening between the rubber sole and the edge of the inner sole', but the difli culty is that if the rubber sole be made comes too hea not well be use in 'a' light Shoe.

' A further object of 'the invention rovide a shoe whereby a rubbersole possessmg capabilities within the objects of the' in-` vention above r referred to,` shall also' possess the capability f presenting around its outer edge and the exposed portion thereof adjacent its edge the finished appearanc'e of a heavy sole.

' The'mannerin' which the obi acts of the invention are'attained canbest be seen and understodd by reference tothe drawings in g bodymg the invention,

' on the line 3-*3 of Fig. 1, and showing in` v to the inner sole, or rather the inner sole s `Fig.-2 is a section of the "sole shown in i Fig. 1 on the line 2-2 of this figure.

Fig. 3 is a section of the rubber sole taken addition a'section of an inner sole with to whchit fastened, and

aby the Fig. 41 5 aside elevation of the ruhber sole shown in Fig. "1. i `In the drawings:-

1 represents the 'bodyof the sole which .is made of rubberor rubbe'r compound. The -sole body is made relatively light except'for the-.thickening thereof as approach is made to the edge of the sole as will laterbeexplaine'd, and except, also,' for the non-slip' corrugato'ns 2, and raised protuberancesior bosses 3 on its outer or bottom face.

beveled portion 5. This beveledportion ex face 7 all around and adjacent the edge 8.

The 'efiectzis thatewhle the body 1 of the' sole is'relatively thin the sole will present along'its--outeredge 8 and top' 'surface 7 adjacent this edge the appearance of aheavy .sole. In fact, the' sole is made relatively -heavyad]acent its outer edge with relaton `to its body and which heaviness or increasede Starting from'apoint 4: on its top surface some distance inwardly removed from its .outer edge 8, the rubber soleis. gradually thickned by an outwardly and upwardly,

thicline'ss is obtained 'by the beveling as Formedor moulded integral with the sole and upstanding from the top surface 7 .thereof at apoint inwardly removed from eo e the edge 8 ofthe sole .is a'rib' or bead`10; i

ready for application and fastening to 'an inner sole-11. Before this is done, however, the cavt left in-the-top of the rubbersole eveling and increased thickness thereof all around itsedge 8, is filled with 'some light material or filling 12 so as to inc rease thethickness of the interier or thinner portion'ofthe rubber sole so that it will substantially equal the thickness of the sole around its edge. The rubber sole is applied ing rib or bead 10 on the rubber sole, the two soles being so co-ordinated that such application may be obtained. After this the two soles are connected by fastenings 13 passed from the bottom or under side of the outer sole through the inner sole at a point well inwardly removed from the outer edges of the two soles.

With all the parts thus eo-ordinated and combined the shoe will be found equjpped with a relatively light rubber sole or one having a relatively light body but which is heavily reinforced around its edge not only by thickening the body of the sole adjaeent its edge but also by the reinforcement obtained by the upstanding rib or bead 10 which acts as a reinforcement in the man ner of a flange. In consequence, although the main body portion of the rubber sole may be relatively light its edge reinforced as it is will not drop away from the edge of the inner sole as might be the case if the edge were made less thick or heavy like the main body. In other words, a proper tight joint is made and will be maintained between the rubber sole andthe edge of the inner sole, and this joint is further protected and sealed by the upstanding rib or bead 10 against which the outer edge of the inner sole is snugly fitting. i

In point of finish the edge of the rubber sole will present the finished appearance of thickness presenting a beveled top surface v havin upward and outward inclination and extending from the top surface of the main body portion of the sole, at a. point inwardly removed from the thickened edge portion thereof, to the flat top surface presented by said relatively thick edge portion of the sole,

and a flange-forming rib rising from the flat top surface of the relatively thick edge portion of the sole at a point inwardly removed from the outer edge of the sole and extending around the toe portion of the. sole and along the sides thereof, the'said inner i sole fitting snugly within said fiange-forming rib and having outer edge contact therewith, a filling between the two soles lying within the cavity formed by the beveled portion of 'the rubber'sole, and means for fastening the, two 'soles together;

a wide, heavy sole. The upstanding rib or bead 10 will conceal the joint between the t-wo soles which adds to the appearance and, at the same time, will provide a fixed marker for obtaining precise and proper co-ordination between the two soles and accurate positioning of the outer or rubber sole with relation to the entire boot or shoe( Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. A rubbersole attachable as an outer sole to footwear having an inner sole, said rubber .sole having an integral moulded structure and comprising a relatively thin main body portion, a relatively thick edge portion all around its outer edge presenting a flat top suface, a portion of gradually increasing thickness presenting a beveled top surface having upward and outward inclination and extending rom the top sur-- face of the main body portion of the sole, at a point inwardly removed from the thickened edge portion thereof, to the flat top surface presented by said relatively thick edge portion of the sole, 'and a flange-forming rib rising from the flat top surface of the relatively thick edge portionof the sole' at a point inwardly removed from the outer edge of the sole and extending around the toe portion of the sole and along thesides thereof. 4
