Figure 1 is a sectional elevation of my improved shoe.
Fig. 2 is a sectional plan view of the same.
Fig. 3 is a section on a a, Fig. 2.
.
Fig. 4 is a section on y y Fig. 1; and
Fig. 5 shows in elevation a boot fitted with my improvements.
A represents the material of the body of the shoe, and A' the lining thereof.
B is the outer sole, above which is preferably laid an inner sole 1, made of thin
metal, to prevent moisture from entering the shoe.
The material between the metal sole I and the inner sole D, or, if the metal sole
is not used, between the outer sole B and the inner sole D, is cut to form passage-
ways b²², running longitudinally, the inner sole D being perforated with holes d'd',
arranged in rows, communicating with said passage-ways, as clearly shown in Figs. 2
and 3.
C is a bulb, made preferably of rubber or any suitable flexible material and
fixed within the boot over the heel thereof and directly under the heel of the wearer.
G is the fresh-air tube, which is open at the top and passes down the back of tho
shoe, terminating in a valve-case F, communicating with the bulb C, and containing
the valve a opening inward toward the bulb.
E is another valve-case connecting the bulb C with the central air-passage 61 and
containing the valve a', opening outward from the bulb. These valves a a¹ are of any
approved construction to keep the circulation of the air in the right direction.
HH are the outlet air-tubes, communicating with the outer passage-ways, b² b³, as
shown in Fig. 2, on each side of the heel, and thence passing upward and around to
the back of the shoe, terminating at the top, preferably on either side of the central
fresh-air tube G.
L is a lining half-sole, the object of which is to cover the bulb C and conceal it
from sight. It is omitted in Fig. 2, so as to show the bulb in place.
The operation of my improved shoe is as follows: At every step of the wearer in
walking the heel of the foot rises within the shoe sufficiently to allow the bulb C to
expand to its full size, thereby drawing the fresh air by suction through the inlet-
tube G into said bulb.
When the heel is again pressed down, the bulb is depressed, forcing the air past
the valve a into the central passage b', and through the perforation d into the shoe.
Thus at every step a bulbful of air is pumped in, the foul air and moisture being.
expelled through the holes d' into the outer passage-ways b¹, and thence through

page_text: the outlet-tubes H into the outer air, the air moving in the direction indicated by the
arrows.
This construction of shoe does not interfere in the least with the comfort of the
wearer, the bulb C being very shallow, and the slightest movement of the heel of
the foot within the shoe in walking being sufficient to create the circulation of air
therein in the manner described.

The same construction may be equally well applied to, a boot, being especially
desirable in rubber boots, which are generally so hot and uncomfortable.
In Fig. 5 I have shown a rubber boot fitted with my improved ventilating devices.
The ventilated boot or shoe is especially adapted for dry hot climates, where ordinary
foot-wear is very burdensome. If desired in extremely cold weather the air-admitting
and air-expelling tubes may be closed, and the shoe will then be as tight as those
ordinarily worn.
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 ventilated boot or shoe having, in combination, a perforated inner sole, and
air-admitting and air-expelling tubes between the outer material and the lining of
the upper, a separate and independent system of longitudinal passage-ways between
the inner and the outer sole communicating with each of said tubes, and an operating
bulb in the heel, all arranged and operating substantially as and for the purposes
described.
2. A ventilated boot or shoe provided between the inner and the outer soles with
a central longitudinal air-admitting passage-way b and independent air-expelling
passage-ways 2 on either side thereof, in combination with a bulb C and an air-
admitting tube G, communicating with said central passage-way b', and provided with
suitable valves, a perforated inner sole, and air-expelling tubes El, communicating
with the passage-ways ², all arranged and operating substantially as and for the
purposes described.
