The shoe upper 35 throughout and its outer configuration is deteris shaped so that when in place on the outer sole,

This bead is press the shoe upper and the outer sole together spaced from the peripheral edge 4 of the sole in a firm union. A heel 14 may be cemented or so as to leave an exposed margin 5 entirely otherwise attached to the outer sole when-dearound the periphery of the sole or thatportion sired. of the periphery around which the bead extends. The relative position of the various parts is 45 This exposed margin 5 corresponds in width, and shown in the cross section of Fig. 2 of the drawis made by molding to correspond in appearance, ing. to the exposed portion of the welt in a similar The depressions 8 in the bead fill with cement shoe of the welted type.

Thus an extremely firm union due to the vertical to the surface of the sole and with the cement and the interlocking engagement of the hypotenuse '7 extending downward and inward. shoe upper with the depressions is formed be- 55 tween the upper and the outer .sole, particularly throughout the area of the bead, rendering it well-nigh impossible to separate the upper from the outer sole without destruction of the one or the other.

The peculiar construction of the bead practically limits the disposition of the cement and prevents the cement from producing an unsightly appearance on the exposed portion of the upper and of the outer sole. The sharply defined vertical edge 6 of the bead gives a distinctive appearance to the shoe and with the exposed margin of the outer sole gives a similar appearance to that which characterizes a welted shoe. v

It will thus be seen that the construction provided by this invention enables a shoe of this type of great strength and of highly pleasing and finished appearance to be economically and'readily manufactured by simple methods. I

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:

1. A vulcanized rubber outer shoe sole having a vulcanized bead integral therewith and projecting above the upper surface thereof and spaced from the edge thereof to leave an exposed margin of the sole corresponding to the weltin a similar shoe of the welted type, said bead having a cross section substantially that of a right angle with the shortest side extending Vertical to the surface of the sole and with the hypotenuse extending downward and inward, and presenting extending downward from the upper surface of the bead a series of spaced depressions having the shape substantially of truncated cones with the smaller ends at said surface.

2. A shoe comprising a vulcanized rubber outer sole having a vulcanized bead integral therewith and projecting above the upper surface thereof and spaced from the edge thereof to leave an exposed margin of the sole corresponding to the welt in a similar shoe of the welted type, the said bead having a cross section substantially that of a right triangle with the shortest side extending vertical to the surface of the sole and with the hypotenuse extending downward and inward and the said bead having a series of spaced depressions extending downward from its upper surface, and an upper having an inturned flange at the bottom conforming to and cemented to said vulcanized bead and projecting into said depressions thus forming an interlocking engagement therewith.

3. A shoe comprising a vulcanized rubber outer sole having a vulcanized bead integral therewith and projecting above the upper surface thereof and spaced from the edge thereof to leave an exposed margin of the sole corresponding to the welt in a similar shoe of the welted type, the said bead having a cross .section substantially that of a right triangle with the shortest side extending vertical to the surface of the sole and with the hypotenuse extending downward and inward and the said bead having a series 'of spaced depressions extending downward from its upper surface and having thev shape substantially of truncated cones with the smaller ends at said surface, and the upper having an inturned flange and a fabric base, at the bottom cemented to said flange with the bottom of the upper conforming to and cemented to said vulcanized bead and projecting into said depressions thus form- 3 ing an interlocking engagement therewith.
