PROVISIONAL SPECIFICATION.
Improvements in and relating to Boot Trees.
I, CLAUDE DEVOST, of 212, Faubourg St. Martin, Paris, in the Republic
of France, Last Maker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in boot trees, one of the improvements
being that the tree can be utilized as a last.
In carrying out the invention the boot tree when it is also to be employed as a last
is formed in two parts from the back or the top to the end of the toe, the upper part
of the toe, or the underside. The two parts can be connected together by any suitable
means such as by a screw having a neck formed by two collars, similar in appearance
to washers, which prevent the screw from moving.
Sometimes the parts forming the last do not require to be fastened together and in
such cases a key-piece is employed which is forced between the two parts in order to
strain or stretch the boot or shoe.
The two parts of the last are sometimes provided with projections or steps serving
as a stop.
As the line which divides the two parts of the last passes through or nearly.
through those parts of the last of almost the largest dimensions it allows of
the hollow last being cast, the hollow being produced naturally during the casting
operation.
As the lasts for goloshes do not require to be made in parts and the underside can
be hollow, such hollow is produced naturally in the casting operation.

COMPLETE SPECIFICATION.
Improvements in and Relating to Boot Trees.
I, CLAUDE DEVOST, of 212, Faubourg St. Martin, Paris in the Republic of France,
Jast Maker, 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 relates to improvements in boot trees, one of the improvements
being that the tree can be utilized as a last.
In order to enable the invention to be fully understood I will describe the same by
reference to the accompanying drawings in which
Figure 1 is a section of a boot tree capable of being utilized as a last :
Figure 2 is a sectional view of a last in two parts provided with a stop:
Figure 3 is a sectional view of a tree made in three parts:
Figure 4 is an elevation of a fastening screw :
Figure 5 is a sectional view of a forked tongue; and
Figure 6 shews the screw and tongue in position.
Referring to figure 1 the tree is made in two parts, the division extending from the
back a, or the top b, to the end a, or the upper part of the toe c, or the underside d.
The two parts can be connected together by any suitable means such as by a screw
having a neck formed by two collars o, which prevent the screw from moving. In
some cases, the screw is fixed to the last by a forked tongue-piece, shewn in figure 5,
which is inserted into the last one arm of the fork passing on each side of the neck
of the screw between the collars thus holding it in position; the tongue-piece can also
Prins 21

screw-thread passing through the fork.
Sometimes the parts forming the last do not require to be fastened together and
in such cases a key is employed which is forced between the two parts in order to
strain or stretch the boot or shoe.
In some cases the parts forming the last are shaped as shewn in figure 2 in full
lines a, or as in dotted lines b, the meeting surfaces of the two parts being formed
with a step or projection which serves as a stop; but a solid nail K fixed in some
part of the meeting surfaces of the last while preventing shaking also serves as a
stop. As the line dividing the two parts of the last passes through or nearly
through those parts of the last which are of almost the largest dimensions it
allows of the last being cast hollow, the hollow being produced during the casting
operation.
As lasts for goloshes do not require to be divided and the underside can be hollow,
such hollow part is produced in the casting operation.
When the last is made in three parts, as shewn in figure 3, the two parts a and e
moet at their lower portions (although this is not necessary) and the sides which
come against the middle curved wedge-shaped piece are similarly curved whereby
the boot tree can be easily withdrawn from the boot or shoe thus dispensing with
the necessity of making the foot movable on the leg, as has been hitherto the case, to
allow of the boot tree being withdrawn from the boot. Small step-like projections may
be formed along the meeting surfaces of the parts.
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. A boot tree which may be utilized as a last and formed of two parts, sub-
stantially as hereinbefore described and illustrated in the accompanying drawings.
2. A boot tree having the sides which come against the central part or parts curved
so as to meet at the lower part of the tree, substantially as, and for the purpose,
hereinbefore described and illustrated in the accompanying drawings.
3. A hollow last of cast metal, the hollow being produced during the casting
operation, substantially as hereinbefore described.
4. In a boot tree or last, the combination with a screw having a neck formed by two
collars, of a forked tongue-piece, substantially as, and for the purpose, hereinbefore
described and illustrated in the accompanying drawings.
