JOSEPH BORRETT of Goldhawk Road, in the county of Middlesex, Boot and
Shoe Manufacturer IMPROVEMENTS IN BOOT AND SHOE SOLE PROTECTING PLATES"
My improvements in boot and shoe sole protecting plates consist in providing a
metal frame of the contour of the sole and having projections nt regular intervals
on its outer edge with spaces left between the projections to receive the sole of
leather or other material which is fixed into the metal frame before described by
means of pressure and afterwards secured by nails in number corresponding with
the raised projections on the metal frame and in order to avoid the frame being
too rigid and firm I cut it at given points in order to produce à natural bend in
the sole.

Where protecting plates are required for parts of the soles of ordinary boots and
shoes already made or otherwise I construct the plates of different shapes but upon
the same principle as above described for the sole frame. These protectors are
constructed of various shapes to suit various parts of the sole and are fixed, by
nailing or otherwise, where protection is required

JOSEPH BORRETT of Goldhawk Road, in the county of Middlesex, Boot and
Shoe Manufacturer "IMPROVEMENTS IN BOOT AND SHOE SOLE PROTECTING PLATES "
My improvements in boot and shoe solo protecting plates consist in providing a.
metal frame of the contour of the sole of the boot or shoe and having projections,
preferably at regular intervals, on it's outer edge or underside with spaces left
between the projections to receive a piece of leather or other material of the shape
of the sole, the said piece being fixed into the metal frame herein before described
by means of pressure, and the combined sole plate thus produced is afterwards
secured by nails, rivets, screws, or other fastenings, to the insole or upper of the
boot or shoe, and in order to prevent the frame from being too rigid or firm I cut
or sever the frame in places or reduce it so as to make it thin at given parts
in order that the sole may be capable of bending to follow the motion of the
foot of the wearer.
"
Where protecting plates are required for parts of the soles of ordinary boots
and shoes already made or otherwise I construct the plates of different shapes
and sizes but upon the same principle as that above described for the complete
sole plates.
These protectors are constructed of various shapes to suit various
parts of the sole and are fixed by nailing or otherwise where protection is
required.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figures 1 and 2, are
plans of the upper and under sides respectively of a frame of metal for use in the
production of a sole protecting plate according to my invention.; figure 3, is a side
elevation of the same; figure 4, is a plan of upper side and figure 5, a section
shewing the said frame to which the leather or the like layer has been applied to
constitute a sole protecting plate for attachment to the upper of a boot or shoe.
Figure 6, is an elevation of a boot with one of the protecting plates fixed thereto
and figure 7, is a plan of the underside of the sole of the same. Similar letters in
all the figures represent similar parts.
a, is the hereinbefore described metal frame of the contour of the sole; the said
frame is cut or severed at b, c, d, and c, and is formed with connecting cross bars f;
it will be obvious that the number of the cuts and of the cross bars may be varied; 8
9, 9, are the projections on the outer edge or underside of the frame a, and also on
the cross bars f. h, are the spaces between the projections g, g.. The layer i, of
leather or other like material is cut to the shape of the frame a, and of the sole,
and pieces are cut at the edges corresponding with the projections g, g, and the
said layer is fixed into the metal frame a, by means of pressure which may be 4
exerted by a powerful press. Figure 4, is a plan, and figure 5, a longitudinal
section of the combined sole protecting plate, it being shewn as having pieces 7j,
of cork or other suitable waterproof material applied for filling up the space or
spaces between the inner sole or welt and the upper surface of the leather, or
the like, in the frame a. When thus put together the outer surface of the 4
leather and the metal of the projections g, are flush at the under part, or the
metal may project slightly if desired. k, k, k, k¹, are holes and slots respectively
in the frame a, for receiving rivets or screws 1, l, to secure the combined sole
plate to the insole or upper m, as shown in figure 7. Instead of the frame a,
being cut or severed as at b, c, d, and e, as hereinbefore described I sometimes 5

page_text: reduce the frame sufficiently thin at these parts to prevent the frame from being
too rigid or firm and to allow a natural bend in the sole, but I prefer to cut or
sever the frame for effecting this object.
It will be evident that the same method of construction may be employed for
various parts of the sole, instead of for a whole sole.
Having thus described the nature of my said invention and the manner of
performing the same I wish it to be understood that what I consider to be novel
and original and therefore claim as the invention secured to me by the herein-
before in part recited Letters Patent is :-
Firstly. The improved boot and shoe sole protecting plate for protecting all, or
a portion or portions of, the sole, consisting of a frame cut or reduced at suitable
parts, and having projections thereon, into which a layer of leather or the like is
forced by pressure so as to form a sole plate of metal and leather, or the like,
combined substantially as hereinbefore described with reference to the accompanying
drawing.
Secondly. A sole protecting plate constructed as hereinbefore described and
claimed, the space or spaces between the under sole or welt and the upper surface
of the protecting plate being filled in with cork or other suitable waterproof
material substantially as herein before described and represented in figures 4 and 5
of the accompanying drawing.
Thirdly. The manufacture and use of boots (or shoes) provided with sole
protecting plates as herein before described and represented in figures 6, and 7, of
the accompanying drawing.
In witness whereof I the said Joseph Borrett have hereto set my hand and seal
this twenty fourth day of October in the year of our Lord one thousand eight
hundred and eighty three
