Improvements in or relating to Boots or Shoes.
We, GEORGE PADMORE, Junior, of Rutland Street, Leicester, in the County of
Leicester, Hosiery Manufacturer, and FRANK LEIGH, of 45 Darnley Road,
Hackney in the County of Middlesex, Gentleman, do hereby declare the nature of
this invention and in what manner the same to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to boots or shoes intended to have an elastic padding of
some description between the sole and insole; the invention applies both to the
boot or shoe itself and the process of manufacture and will be best understood by
reference to the accompanying drawings in which
Figure 1 is a side elevation, and
Figure 2 a central longitudinal section of a boot or shoe.
Figure 3 is an underside view of the sole and heel.
Figure 4 is a transverse section on lines 4-4 of Figure 1.
Figure 5 is a transverse section on lines 5-5 of Fig. 1, and
Figure 6 is a transverse section on lines 6-6 of Fig. 1.
Figure 7 is a plan of the recessed heel lift.
Figure 8 is a plan of the block.
Like letters indicate like parts throughout the drawings.
In manufacturing this boot or shoe the insole A and upper B are placed upon a
last and a welt C is added in the ordinary manner, excepting that the welt is much
wider than usual as is shown in dotted lines in Figure 4. A block of the required
thickness is then placed upon the insole; this block is preferably made in two or
more parts, in Figure 8 it is represented as being made in three parts DD' D' these
being provided with grooved and tongued joints so that the part D may be readily
withdrawn when the block is to be removed.
The block may be made of metal, wood, leather or other suitable material and
its thickness determines the space or cavity between the insole A and sole E.
The sole E is temporarily attached to the block and if the latter is of metal a
suitable number of holes must be provided for the purpose.
The projecting portion of the welt C is then brought over and secured to the
sole E by stitching. pegging, or the like, as will be well understood. The block is
then withdrawn leaving a compressible space between the inner and outer soles and
the surrounding welt into which we may place any suitable form of padding whether
"pneumatic" (compressed air) pad F, a coil of tubing either containing compressed
air or not, or a relatively solid pad such as cellular rubber, felt, or other suitable
elastic material or filling.

The waist G is channelled or cut away as at G', Figure 3, if a pneumatic"
(compressed air) pad is employed, to receive the air-tube Fi and valve F the
latter being accommodated in the space provided for the purpose in the heel as
hereinafter described; when it is required to use the valve it may be drawn out of
the recess in the heel and subsequently replaced.
When it is intended to apply an air pad we have found it desirable to provide
the insole with strips of tempered steel or the like for the purpose of retaining the
contour of the insole when the pad is inflated.
The heel is preferably built up in the following manner, as may be seen by
reference to Figure 5. A welt C similar to that described above but broader is
attached to the insole A of the heel and upon this are placed one or more lifts H
provided each with a recess H', as shown in Figure 7, to accommodate the valve
and air-tube when the pneumatic pad, as shown in Figure 2, is employed. When

page_text: the requisite number of these lifts have been built up, a solid lift I of ordinary form
is applied and on this in the space represented by J is placed a metal plate of any
convenient thickness, another lift I' is placed upon the metal plate and then the
edges of the welt are turned in over the lift, as at C¹, and affixed thereto by
stitching nailing or other convenient means. Any number of lifts may now be
built upon the preceding lifts the metal plate being used for the purpose of rivetting.
The metal plate is then withdrawn and in the compressible space thus provided we
insert an inflatable pad, indiarubber, or other flexible material K to give elasticity
to the heel.
One or more flaps or covers of leather metal or other suitable material may if
desired be employed to entirely close the opening in the instep and heel or these can
be left open without much detriment to the boot.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1. A boot or shoe having a compressible space between the insole and sole
substantially as described and illustrated in the accompanying drawings.
2. In the manufacture of a boot or shoe forming a compressible space between
the inner and outer sole by the interposition of a removable block over which the
welt is stretched and attached to the sole substantially as described and illustrated
in the accompanying drawings.
3. The combination with the soles of a boot or shoe of a broad welt such as C
substantially as and for the purpose described and illustrated in the accompanying
drawings.
4. The combination of a welt with the heel of a boot or shoe.
5. The combination with the heel of a boot or shoe of a broad welt such as C C
substantially as and for the purpose described and illustrated in the accompanying
drawings.
6. In a "pneumatic" boot or shoe the application of steel or similar strips to the
insole for the purpose of preserving its contour when the pad is inflated.
7. A "pneumatic" boot or shoe having a channel in the waist and a recess in the
heel for the accommodation of the air tube and valve substantially as described and
illustrated in the accompanying drawings.
8. In the manufacture of a boot or shoe forming a compressible space in the heel
by the interposition of a removable plate over which the welt is stretched and
secured to the heel substantially as described and illustrated in the accompanying
drawings.
9. The complete boot or shoe substantially as described and illustrated in the
accompanying drawings.
