RUBBER Bo'oT oR SHOE.

SPECIFICATION forming part of Letters Patent N o, 541,610, dated June 25, 1895. Y

Appiioation filed April 1s, 1895.

To all whom may concern.:

Be it known that I, CHARLES L. HIGGINS, a subject of Victoria, Queen of Great Britain and Ireland, residing at Montreal, in the Do- 5 minion of Canada, have invented a new and useful Improvement in Rubber Boots or Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of 1o this specification, in explaining its nature.

The inventionl relates to a rubber boot or shoe especially adapted for the use of miners. Such boots have been made of rubber with the exception of the heel and outsole which I5 have been attached to the rubber insole ofthe boot or shoe in the ordinary Way of attachment, namely, by nails or pegs driven through the sole into the rubber insole of the bootvor shoe. This construction has been found to 2o be objectionable in that the holes caused by the uniting nails or pegs oftenafforded channels or passages by which water or moisture found its way to the' interior of the boot or shoe, and also because the boot or shoe so con` structed was very stiff or inflexible, and where two leather soles were used, as was often the case, of course the disadvantages in this respect were increased.

vIn practicing my invention l take an insole 3o and the usual upper part of the boot or shoe and treat thein in the ordinary way for attachment to each other by vnlcanization and vI also unite to the insole and the turned in edge of the upper, by vulcanization, two or more layers of duck, canvas, or other suitable fabric preferably shaped to cover the entire under surface of the insole and to extend about the edge of the boot or shoe to form a section in the nature of a welt to which the 4o leather sole is united; and in the furtherconstruction of the boot or shoe a leather sole is secured to this intermediate canvas or duck section'by stitches passing through the edge of the leather sole and this welt or exposed edge of the canvas or duck section; and the sole is also further secured inside the line of sewing to the canvas or duck section by rubber cement. This provides a union between the leather sole and the remainder of the boot 5o or shoe which does away with all holes ex- Serial No. 545,562. (No model.)

tending to the insole to 'the interior of the boot or shoe, and it also forms a foundation for the reception of another leather or outsole of a nature to permit the said sole to be secured tothe inner leather sole by nails or pegs, it being especially desirable in boots or shoes of this character that the outer sole shall be so secured; and I use for such purpose nails with large heads, such as hob nails, for the purpose of increasing the wear of the 6o boot or shoe and also for the purpose/of providi'ng points or projections extending from the outsole to prevent slipping.

Referring to the drawings, Figure l is a view in longitudinal section of the boot. Fig. 2 is a View in cross-section representing one stage in its manufacture. Fig. 3`is a view representing upon the same section the second stage in its manufacture. Fig. 4 is a view upon the same section representing the final 7o stage in its manufacture.

` A represents the upper part of the boot or shoe. It is of the usual rubber fabric.

B is the insole which is also of rubber stock and to which the edge of the upper is united by vulcanization.

C represents the intermediate section of fibrous material preferably in the form of two or more layers of duck or canvas united together by'a rubber compound and also to the 8cV insole and edge of the upper and thereto by vulcanization, this intermediate section C having an edge cin the nature of a welt but which may extend entirely around the heel end of the boot or shoe if desired. To this extension or welt c`is then secured the leather sole D by stitches which extend through it near the edge and through the welt or extension outside the upper. d represents this line of attachment. The sole is further united to 9o the intermediate section C by rubber cement. The leather outsole E is then attached to the remainder of the boot or shoe by nails or fastenings driven through it into 4the intermediate sole D but not through the. rubber insole B, and for this purpose hob nails or any other Wearing nails may be employed, and the heel F is attached to both leather soles in the usual way by nailing, the fastenings, however, not extending through the insole.

IOO

It will be seen that the rubber insole, the intermediate fibrous section C and the leather sole D form a very firm body or foundation for receiving and holding the fastenings for securing the outsole and the heel which may not extend through the insole.

The advantages of the invention arise from the increased flexibility provided the soles and also from the Waterproof character ofthe construction, as all ways by which moisture can find access to the boot or shoe through the sole are done away with.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. A rubber boot or shoe having a rubber insole, the intermediate fibrous Waterproof section united to the insole by vulcanization and having an edge extended beyond the edge of the upper, a leather sole secured to this intermediate section by rubber cement and by stitches passing through the exposed edge thereof and the edge of the sole, as and for the purposes described.

2. A rubber boot or shoe having a rubber insole, a rubber upper and a Waterproof vulcanizable intermediate fibrous section united to each other by vulcan ization, the said fibrous section having an exposed edge to actas a Welt, a leather sole secured to said fibrous section by rubber cement and by stitches passing through it near its edge and the edge of said fibrous section and an outsole and heel united to the intermediate leather sole D by fastenings Which extend through it into said sole but not through the insole, as and for the purposes described.

CHARLES L. HIGGINS.
