Improvements in or relating to Sectional Heel Lifts for use in the
Manufacture of Boots and Shoes.
I, JAMES HEWITT of 17 Upper Tichborne Street Leicester, Manager of Public
Company, 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 :-
This invention has reference to the manufacture of sectional heel lifts for use in the
manufacture of boots and shoes and is designed, firstly, to permit of the utilization of
small or scrap pieces of leather in the manufacture of same, and, secondly, to overcome
an objection frequently made against sectional lifts of ordinary make which, when
nailed together to form a heel, present a number of cracks or interstices on the
outside edge which have to be filled up before the heel can be finished, and which
during the wear of the boot or shoe often gape or open, presenting an unsightly
appearance and offering facilities for the wet to penetrate to the central portion of the
body of the heel and thereby accelerate its wear.
Sectional heel lifts constructed according to this invention, as hereafter described,
possess a continuous, unbroken external edge, excepting on the front or breast
portion.
In this state it is as readily finished and as durable in wear as heels built of lifts
each composed of one entire piece of leather.
According to this invention I produce a lift shaped piece of leather by means of a
knife or mould, the contour of which may approximate an ordinary entire piece heel
lift but is preferably not so wide across the breast.
This lift-shaped piece of leather is then cut in a line centrally from the breast and
continued to within a given distance of the outer or back edge.
The incision thus formed may be expanded and one or more triangularly or other
suitably shaped pieces of leather inserted therein, thereby imparting to the lift a shape
and size equivalent to the contour of the heel upon which it is to be placed.
In order that the process of making sectional heel lifts according to this invention
may be more clearly understood, reference is made to the accompanying drawings.
A piece of leather of the shape shown in Figure 1 is first produced by means of a
knife or mould in the ordinary way; it may then be cut along the lines a. b. c in
Figure 2; or a knife may be constructed in such a manner as to admit of a piece of
leather shaped and ent as is shown in Figure 2 being produced in one operation.
After having been cut as indicated in the last named figure the lift will assume the
shape shown in Figure 3. A small triangularly or wedge shaped piece of leather d.
nay then be forced edgewise in the incision e. which will expand the lift and cause it
to assume the shape and contour of an entire piece lift as shown in Figure 4.
An alternative inethod of cutting lifts is shown in Figure 5.
A knife may be constructed to remove a piece from the lift leaving an opening f.
and severing it along the line g. ; one or more small pieces of leather h. j. may then
be inserted in the incision to cause the lift to form the shape shown in Figure 6.

tion and in what manner the same is to be performed, I declare that what I
claim is :-
The manufacture of sectional heel lifts substantially in the manner herein before
described and illustrated in the accompanying drawings.
