PROVISIONAL SPECIFICATION.
Improvements in Lasts and Boot Trees.
I, EDWIN BOSTOCK Junior, c/o Edwin Bostock of Stafford, Shoe Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to lasts and boot trees formed of two parts viz., a heel part
and a toe part hinged together, and has for its chief object to provide an improved
hinge for the said parts.
According to my invention I secure, by screws or otherwise, a circular rod or
bar to one portion preferably the heel portion of the last or boot tree, near the
sole thereof, and I drill or otherwise provide a transverse hole in the other or toe
portion of the last or boot tree to receive the said rod and to form a socket in
which it can turn. The rod forming the hinge is then slid or passed into the socket
prepared for it and plugs are secured at each end of the socket to retain the parts
in position.
For what are known as making-lasts I preferably extend the sole of the toe part
of the last rearwardly and provide a corresponding recess in the heel portion to
receive the said extension. The ends of the extended part and of the recess aforesaid
are preferably curved. This form of construction gives additional strength to the
last, and enables it to withstand a heavy stress.
In the case of a making last rigidity while in use is ensured by fixing the last
sole upward on a jack that has a peg to fit a hole in the upper part of the heel,
and by a rest to support the toe part of the last.

I, EDWIN BOSTOCK Junior, c/o Edwin Bostock of Stafford, Shoe Manufacturer,
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:-
My invention relates to lasts and boot-trees formed of two parts, viz. a heel part
and a toe part hinged together and has for its chief object an improved hinge for
the said parts.
In order that my invention may be clearly understood I will describe the sanie
with reference to the accompanying drawings, in which,
Figure 1 is a side elevation of my improved last.
Figure 2 is a side elevation of the two parts of the last detached from each
other.
Figure 3 is an end elevation of the heel part showing the hinge.
Figure 4 is a side elevation of a making-last to be hereinafter more fully
described.

page_text: Like letters denote corresponding parts in the several figures.
A is the toe portion of the last; B is the heel portion thereof.
In carrying my invention into practice I secure to the heel portion B of the last
a circular rod or bar C, by means of screws C¹ or otherwise, and I drill or other-
wise provide a transverse recess A' in the toe portion A of the last to receive the
said rod C and to form a socket in which the rod can turn.
The said recess or
socket A¹ is open at the side as clearly shown in Figure 2. The rod C which is
somewhat shorter than the width of the last as seen from Figure 3 is slid or passed
into the socket or recess A' and plugs D are then secured in each end of the said
socket to retain the parts in position.
The dotted lines in Figure 1 show the position of the heel portion when the last
is being removed from or introduced into a boot.
For what are known as making-lasts I preferably extend the sole of the toe part
of the last rearwardly, as shown at A2 in Figure 4 and I provide a corresponding
recess B in the heel portion B to receive the said extension. The end of the
extended part A2 and of the recess B¹ may be curved. This form of construction
gives additional strength to the last, and enables it to withstand a heavy stress.
In the case of making-lasts rigidity in use is ensured by the jack-post E that fits
into a hole provided in the upper part of the heel portion B of the last, and by a
rest F to support the toe part A of the last.
My improved hinge may be also adapted for use with boot-trees as well
as lasts.
It is obvious that I may reverse the position of the rod and socket, that is to say,
I may secure the rod to the toe portion of the last, and form the socket in the heel
portion.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
--
1. For a last or boot-tree made in two parts, a hinge comprising a rod secured to
one part and a socket provided in the other part to receive the said rod, substantially
as described.
2. A hinged last constructed substantially as described with reference to
Figures 1, 2 and 3 or to Figure 4 of the accompanying drawings.
