Improvements relating to the Manufacture of Boots and Shoes.
I, ALEXANDER WEISZ, of No. 64, Klosterstrasse, Berlin, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
6
The present invention comprises a method of producing boots and shoes, in
which the sole is affixed to the upper by means of screws in such manner that
the upper is held to the sole by the head of the screw, and the thread of the
screw enters the sole, its point automatically upsetting," or turning over
against the ground when the boot is in wear, and so forming a rivet-like fastening
of the sole to the upper. By this method the accidental separation of the sole
from the upper is rendered impossible, and therefore the durability of the boot
or shoe is correspondingly prolonged.
The accompanying drawing shews one example of carrying out the invention,-
Fig. 1 shewing the interior of a shoe at first turned outwards;
Fig. 2 a section of the sole corresponding to Fig. 1, after the upper has been
united thereto by the screws; and
Fig. 3 a section of the completed shoe.
The method of manufacturing boots and shoes in vogue up to the present time,
and, more particularly, the mode of the attachment of the upper to the sole, is
carried out in such manner that after the insole has been laid upon the last, the
upper is united by means of its edges to the insole, whereupon the welt (in welt-
sewn boots and shoes), or the sole itself, is then united to the upper in some
suitable way.
It frequently happens here, however, that the upper, by reason
of the nails or the stitches becoming loose, comes away from the sole. To pre-
vent this is the object of the method hereinafter described.
The attachment of the sole a is effected in this case in such a manner, that
after the sole has been laid with its outer side upon the face of the last (in
contra-distinction to the commonly prevailing method of having the inner side
next the face), the upper b, which it is desired to unite to it, is similarly laid
upon the last with the outside, instead of with the inside, next thereto, and the
edge c of the upper, after being smoothed down and fitted to the last is screwed
to the soles by screws d, instead of the usual nailing or sewing, the thread e of
the screws entering the soles, and firmly securing the upper thereio with their
heads.
When the parts are secured together, the last is taken out and the upper and
sole reversed, so that the outsides of both portions, formerly turned inwards
toward the last, are now outwards, so that, in use, the points of the screws pro-
jecting through the sole, will come in contact with the ground. The action of
walking will form a head upon the point of the screw, that is to say, the points
will become more or less upset" by the walking, and
<<
SO rivetted.
This provides a securer and firmer hold of the sole to the upper, till both are
absolutely worn out. There is also nothing to hinder the rivetting over of the
screw ends immediately after their insertion.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
The herein described method of manufacturing boots and shoes, wherein the
sole a and upper bare put upon the last outside-in, and the edge of the upper
overlapping the sole, is attached to the sole in the manner explained by a num-
ber of countersunk or flat-headed screws d, and wherein, after the removal from
the last, the boot or shoe so made is reversed, the former inside being now the
outside, thus exposing the points of the screws to the ground surface, as and for
the purpose above set forth.
