PROVISIONAL SPECIFICATION.
Improvements in Lasts for Shoes.
1, JEAN MARTIN SPENLÉ, of Autet, in the Republic of France, Engineer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to the wooden lasts ordinarily used by boot and shoe makers.
Such lasts consist of two parts, the upper part, or instep, being capable of ready
removal or replacement, and my invention has for its object a novel method of readily
and firmly connecting and disconnecting the parts when required.
For this purpose I connect the front of the two parts together by means of a pin or
peg fitting into them and arranged diagonally so that its lower end is inclined toward
the toe of the last. The back end of the upper part is connected to the lower part by
means of metal tubes or sockets fixed into each part in the same central line but the
lower end inclining backward toward the heel of the last.
These metal tubes serves as a guide for a central pin which fits in them freely and
is provided with a spiral spring round its lower part the tendency of which spring is to
raise the pin, and the pin also has near the middle of its length a lateral projection
which fits into a vertical slot in the side of the lower tube, the said slot also having a
lateral branch at its lower end, so that if the pin be pressed down and then turned
partly round the projection engages in the lateral slot and is held down. If the pin
be turned partly round in the other direction, it is driven up by the spring as soon as
the projection has left the lateral slot. The upper end of the pin is provided with a
transverse notch, or is otherwise formed to receive a screw driver or equivalent tool
by which it is turned round.
If the upper part of the last be adjusted into its proper position upon the lower
part, and the pin be released by the tool, it springs up into the guiding tube in the
upper part, and prevents the latter from moving laterally, whilst the angular position
of the inclined peg or pin in front and of the inclined pin at the back prevents the
two parts from separating until the back pin has been again forced down and turned
partly round by the tool.

COMPLETE SPECIFICATION.
Improvements in Lasts for Shoes.
I, JEAN MARTIN SPENLE, of Autet, in the Republic of France, Engineer, 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 and
accompanying drawing that is to say :—
My invention relates to the wooden lasts ordinarily used by boot and shoe makers.
Such lasts consist of two parts, the upper part, or instep, being capable of ready
removal or replacement, and my invention has for its object a novel method of readily
and firmly connecting and disconnecting the parts when required.
In the accompanying drawing which is in illustration of the invention, as shewn in
figure 1, I connect the front of the two parts together by means of a pin or peg a
fitting into them and arranged diagonally so that its lower end is inclined toward the
toe of the last. The back end of the upper part is connected to the lower part by
means of a novel attachment & consisting of metal tubes or sockets d, k, fixed into the
parts in the same central line but the lower end inclining backward toward the heel of
the last, and a sliding pin c.

page_text: In figure 1, the two parts of the last are shewn fastened together, the attachment at 6
being shewn in section. Figure 2 is a view from above. Figures 3 and 4 are different
views and sections of the fastening attachment. Figure 5 represents a metal socket k
which is fitted into the upper part of the last and receives the pin c which fits freely
in a socket d fixed in the lower part and is provided with a spiral spring round its
lower part the tendency of which spring is to raise the pin, and the pin also has near
the middle of its length a lateral projection which fits into a vertical slot in the side of
the socket d, the said slot also having a lateral branch at its lower end, so that if the
pin be pressed down and then turned partly round the projection engages in the
lateral slot and is held down. If the pin c be turned partly round in the other
direction, it is driven up by the spring as soon as the projection has left the lateral
slot. The upper end of the pin is provided twith a transverse notch, or is otherwise
formed to receive a screw driver or equivalent tool by which it is turned round.
If the upper part of the last be adjusted into its proper position upon the lower
part, and the pin be released by the tool, it springs up into the guiding tube in the
upper part, and prevents the latter from moving laterally; whilst the angular position
of the inclined peg or pin a in front and of the inclined pin at the back prevents the
two parts from separating until the back pin has been again forced down and turned
partly round by the tool.
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 :-
In order to fix together the two parts of a last, the moveable inclined pin e, forced
up by a spring in a slotted socket into a tube k, in combination with the peg or
pin a inclined in the opposite direction, substantially as described and shewn in the
drawing.
