IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND SHOES
Year: 1881

page_text: LETTERS PATENT to Thomas Laycock, of Northampton, in the County of
Northampton, Boot and Shoe Manufacturer, for an Invention of "IMPROVE-
PROVISIONAL SPECIFICATION left by the said Thomas Laycock at the
Office of the Commissioners of Patents on the 7th September 1881.
THOMAS LAYCOCK, of Northampton, in the County of Northampton, Boot and
Shoe Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND
SHOES."
This Invention relates to improvements in the manufacture of boots and shoes,
whereby the sock now usually employed in machine made boots for covering the
tacks, tingles, and the like projecting from the surface of the insole is not required,
and the improvements consist in manufacturing boots and shoes with what I term
a "double insole" in the manner hereinafter described.
In carrying out my Invention the upper is manufactured in the usual manner,
but instead of employing an "insole" of the usual thickness I employ an insole
made of two thicknesses; the upper is lasted to one of these parts of the "insole"
in the usual manner and the middle and outer soles tacked on; the boot is then
removed from the last and the second part of the insole is placed over the first part
in the inside of the boot, the soles are then screwed to the double insole, the screws
passing into or through the whole so as to secure the upper part of the insole to
the lower part thereof.
In cases where the outer sole is sewn to the middle sole, the middle sole is screwed
to the double insole in a similar manner to that herein before described.
By the employment of this improved or double "insole" it will be evident that
the ends of the tacks, tingles, and the like projecting from the surface of the under
portion of the double "insole" will be covered by the upper portion of the insole,
so that the sock usually employed will not be required, and boots and shoes
inanufactured according to my Invention will be smoother on the insole than those
made by hand.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Thomas Laycock in the Great Seal Patent Office on the
6th March 1882.
THOMAS LAYCOCK, of Northampton, in the County of Northampton, Boot and
Shoe Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF BOOTS AND
SHOES."
This Invention relates to improvements in the manufacture of boots and shoes,
whereby the sock now usually employed in machine made boots for covering the
tacks, tingles, and the like projecting from the surface of the insole is not required,
and the improvements consist in manufacturing boots and shoes with what I term
a "double insole," forming a combined insole and sock in the manner substantially
as hereinafter described.
In carrying out my Invention the "upper" is manufactured in the usual manner,
but instead of employing the usual insole I employ an "insole" made of two
thicknesses or parts; the "upper" is lasted to one of these parts of the "insole" in
the usual manner, and the middle and outer soles tacked on; the boot is then
removed from the last, and the second part of the "insole" (which takes the place
of the ordinary sock) is placed over the first part of the "insole" in the inside of
the boot, the soles are then screwed to the double "insole," the screws passing into
or through the whole so as to secure the upper part of the "insole" to the lower
part thereof.
.
In cases where the outer sole is sewn to the middle sole or welt the middle sole
or welt is screwed to the double "insole" in a similar manner to that hereinbefore
described.
Where the outer and middle soles are sewn to the "insole" the second part of
the "insole" (taking the place of the usual sock) is subsequently fixed by a
sufficient number of screws, either from the middle sole or welt, or from the outer
solc.
In the accompanying Drawing, Figures 1 and 2 represent cross sections of boots.
manufactured according to my Invention, similar letters in both the Figures
representing similar parts.
In Figure 1, a is the usual upper, b and c the two parts or thicknesses forming
my improved "insole." The upper a is lasted to the part c by the tingles d in the
usual manner, and the outer sole e tacked on; the boot being then removed from the
last, the second part 6 of the "insole" (which takes the place of the ordinary sock)
is then placed over the first part c of the "insole." The outer sole e is then screwed
(by the standard screw machine or any other suitable screwing machine) to the
double insole," the screws f passing through the outer sole e, the upper a, and the
part of the insole," and into the part b of the "insole," so as to secure the latter
to the lower part c of the "insole."
"
"
Figure 2 shews a section of a boot in which the outer solo is sewn to the middle
sole or welt. In this case the middle sole or welt g is screwed to the double
"insole" in a similar manner to that shewn for the outer sole in Figure 1; the
outer sole e is then sewn to the middle sole g in the usual manner.
"
By the employment of this improved or double "insole it will be evident that
the ends of the tacks, tingles, and the like, projecting from the surface of the under
portion of the double "insole" will be covered by the upper portion of the " insole,"
so that the sock usually employed will not be required, and boots and shoes
manufactured according to my Invention will be smoother on the "insole" than
those made by hand.

page_text: Having thus described the nature of my said Invention and the best means
with which I am acquainted for carrying the same into effect, I would have it
understood that what I claim is,―
"
Firstly. The manufacture and use of boots and shoes having what I term a
double insole," or combined insole and sock, substantially in the manner and for
the purposes hereinbefore described.
Secondly. I claim a boot or shoe having an "insole" in two parts, one of such
parts being placed into the boot or shoe after the boot or shoe has been taken
from the last, or lasted, the said second "insole" forming a sock for covering the
tacks, tingles, wax, and the like, being secured to the middle sole, welt, heel, or
outer sole from the outside, substantially in the manner hereinbefore described.
In witness whereof, I, the said Thomas Laycock, have hereto set my hand
and seal, this Fourth day of March, in the year of our Lord One thousand
eight hundred and eighty two.
THOMAS LAYCOCK. (L.S.)
