Improvements in Boots and the like.
I, JULES LOUIS CHAPPUIS, Shoemaker, of Rödingsmarks 15 Hamburg in the
Empire of Germany 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 :-
This invention for improvements in boots and the like has for its object to
effect, by means of an air conduit between the inner sole and the foot, a more
favourable evaporation from the skin and thereby to prevent an undue secretion of
perspiration, and furthermore by changing the height of the inner sole to adapt
the shoe or boot to the particular condition of the foot which is of importance
when they swell as the result of heavy exertion.
In the accompanying sheet of illustrative drawings:
Figures 1, 2, and 3 show partly in section three different forms of a boot con-
structed according to this invention.
Figures 4 and 5 are plans of the inner soles of boots shown in Figures 2 and
Figure 3 respectively.
The perforated sole S of aluminum or other light metal which may be covered
with leather, consists of a body part a and toc part joined together near the ball
of the foot by the hinge c. Rubber or other elastic buttons p are fixed in
symmetrical positions to the lower surface of the main sole, and support the sole S
and leave between it and the leather bottom sole a free air space. In Figure 1
this space is shown communicating with the atmospheric air by an opening o in the
heel which is covered by the cap k in such manner that only the slits corresponding
to the shape of the heel remains open. If required the space between the two
soles can be fitted with a loose material such as wool, hair, and the like.
In Figure 2 an adjusting apparatus is attached to the metal sole. It consists of
a metal block fastened to the underside of the sole and the lower inclined surface
of which slides on a wedge shaped metal base u let into and fastened to the heel
leather and formed with a flange which is covered on the outside by the heel
leather and has cut in it a slot i through which is inserted from the outside a
screw e engaging in a tapped hole in the block k³. Between the head of the screw
and the heel is a washer d and on either side of the washer air holes. By rotating
the screw the block is moved forwards or backwards and thereby raises or lowers
the metal sole S.
In the modification shown in Figure 3 a pin z with a screw thread is fixed by
means of a broad plate / to the lower surface of the sole S and its free end projects
through a slot over the heel which at this point is provided with a ratchet toothed
plate p². A washer plate d also ratchet toothed is pressed against the plate p² by
a nut m on the end of the screwed pin which together with the sole S is thereby
firmly secured in the slot ³.
The form of the latter allows a variation in the height of the pin z which is
raised by raising the washer plate d. Air holes are also provided in this con-
struction.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A ventilating sole for boots and the like consisting of the hinged metal sole
supported above the lower sole by elastic buttons, the space between the soles
communicating with the outer atmosphere by suitable openings substantially as

raising or lowering the metal sole, the air space between the soles communicating
with the atmosphere by means of suitable openings substantially as described.
3. The improvements in boots and the like, substantially as described with
reference to the drawings.
