Improvements in or relating to Waterproof Foot Coverings.
I, WILHELM SPIESS, of 3A, Werderstrasse, Stuttgart, 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: -
The object of the present invention is a boot which is characterised by a special
waterproof lining which protects the foot from wet and moreover keeps the foot
warm in cold weather.
A boot with this kind of lining is illustrated in the accompanying drawing.
Figure 1 shews one constructional form of the lining in sectional elevation.
Figure 3 is a section (enlarged) of Figure 1, at A-A.
Figure 5 shews a portion of the lining of Figure 1 in section on a larger
scale.
Figures 2 and 6, 4 and 7 illustrate other forms of construction in sectional
clevation and transverse section, the two latter figures being enlarged transverse
sections at B-B Fig. 2 & at C-C Fig. 6 respectively.
This boot is distinguished from those already known, by being lined with a
waterproof lining a. As will be seen from Figure 5 the lining consists of two
layers bb of linen or other woven material, between which is inserted a rubber
layer c. This rubber layer prevents moisture from penetrating, while the foot
is kept warm by means of the woven lining combined with the said rubber
layer.
In the form of construction illustrated in Figures 1 and 3 which shew a boot
of the usual make, the waterproof lining a lines the whole upper part of the
boot.
In the constructional form shewn in Figures 2 and 4 the waterproof lining a
also forms a lining to the inner sole d, and a second inner sole e must then be
placed over the lining. As the ends of the lining a are thus firmly sewn
together underneath the inner sole e and above the inner sole d the boot is
perfectly waterproof.
The constructional form shewn in Figures 6 and 7 illustrates a boot in which
the waterproof lining only extends over a part of the boot, that is no higher
than the level of the instep while the lining of the upper and back part of the
boot consists of ordinary leather or woven fabric f and is sewn to the lining a.
This arrangement can be used for the ordinary make of boot or for that illus-
trated in Figures 2 and 4.
This arrangement of a lower waterproof lining with an ordinary upper lining
can be used for shoes or boots with any kind of fastening, and prevents the
double layer of woven fabric enclosing the rubber layer (see Figure 5) being
injured by friction, or other cause during fastening or unfastening.
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:-
1. A waterproof lining (a) for boots and the like, consisting of a centre layer

page_text: of rubber and two outer layers of woven material, which renders, the boot water-
proof and keeps the foot warm at the same time, substantially as described.
2. A lining for boots consisting of a lower waterproof lining as claimed in
Claim 1 in combination with an upper lining of leather or woven fabric, sub-
stantially as described.
