Improvements in or relating to Lasts used in the
Boots and Shoes.
We, CHARLES HENRY DALE, and FREDERICK JAMES DALE, trading as H. & F.
ale, 23B, Oxford Street, Leicester, Engineers, do hereby declare the nature
f this invention to be as follows:-
This invention relates to lasts used in the manufacture of boots and shoes
and has for its object a certain improvement applicable to wood lasts and the
nature of which is hereinafter referred to.
The bottoms of wood lasts, as is well known, have leather plugs or discs let
or sunk into them at the points where the sole is temporarily attached to the last
to receive the tacks which are used for such attaching purposes.
It frequently happens that the operator uses tacks too great in length or
hammers them in so far that they pass through the leather plug and into the
body of the last itself, in which case they become so firmly embedded that when
it is desired to detach the sole and partly finished boot or shoe from the last
they offer such resistance that the boot is removed leaving them in the last.
After this has occurred a few times the last is of no further use until these
tacks have been removed and it has been re-plugged.
Our invention is designed principally to overcome this disadvantage by means
which prevent the tacks entering the body of the last.
Our invention consists of a wooden last having let into its undersurface at
20 the points where the sole is temporarily attached thereto, a metal socket or
thimble open at its outer end to admit a plug of leather or other like flexible
substance to receive the attaching tacks and having a metal back or end which
will prevent the points of the tacks entering the body of the last.
The socket may be screw threaded or otherwise roughened or serrated on i
25 exterior surface to hold it in place or it, and the leather plug also if desire
may be overlapped by the usual metal sóle plate attached to wood lasts for t
same purpose.

The metal socket may have parallel, diverging or converging sides and a f
or curved back or end.
With converging sides, the socket would hold the plug in position with
extraneous means.

Improvements in or relating to Lasts used in the Manufacture of
Boots and Shoes.
We, CHARLES HENRY DALE, and FREDERICK JAMES DALE, trading as H. & F.
Dale, 23B, Oxford Street, Leicester, Engineers, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:―
This invention relates to lasts used in the manufacture of boots and shoes
and has for its object a certain improvement applicable to wood lasts and the
nature of which is hereinafter referred to.
The invention has particular reference to the bottoms of wood lasts of the
well known type which have leather plugs or discs let or sunk into them at the
points where the sole is temporarily attached to the last to receive the tacks
which are used for such attaching purposes.
It frequently happens that the operator uses tacks of too great a length or
hammers them in so far that they pass through the leather plug and into the
body of the last itself, in which case they become so firmly embedded that when
it is desired to detach the sole and partly finished boot or shoe from the last
the tacks offer such resistance that the boot is removed leaving them in the last.
After this has occurred a few times the last is of no further use until these
tacks have been removed and it has been re-plugged.
Our invention is designed principally to overcome this disadvantage by means
which prevent the tacks entering the body of the last.
Our invention consists of a wooden last having let into its undersurface at
the points where the sole is temporarily attached thereto, a metal socket or
thimble open at its outer end to admit a plug of leather or other like flexible
substance to receive the attaching tacks and having a metal back or end which
will prevent the points of the tacks passing through and entering the body of
the last.
侮
The socket may be screw threaded or otherwise roughened or serrated on its
exterior surface to hold it in place or it, and the leather plug also if desired,
may be overlapped by the usual metal sole plate attached to wood lasts for the
same purpose.
The metal socket may have parallel, diverging or converging sides and a flat
or curved back or end.
With converging sides, the socket would hold the plug in position without
extraneous means.
The invention will be fully understood from the following further description
having reference to the accompanying drawing, in which
Figure 1 is a central longitudinal section of a portion of a wood last embody-
ing our invention.
Figure 2 is a plan of the bottom or underside of a last similarly constructed.
Figure 3 is a view partly in elevation and partly in section of a metal socket
or thimble and its leather plug, detached from the last.
Figure 4 is an elevation of a socket serrated on its outer surface.
A represents the wood body of the last, B a metallic socket or thimble fitted
tightly within a hole therefor made in the bottom of the last, C a plug of leather
or equivalent material fitting snugly within the socket B, and D a metal sole
plate fixed over the bottom of the last by a series of screws E and furnished with
holes D of smaller diameter than the sockets so that the circumferential marginal
edge of the said plate around the said hole overlaps the upper edge of the sockets
and keeps them in place.

The said plate may also overlap the plug C
referably constructed with three sides one of which forms the
atter will offer such resistance to the point of any tack driven through the plug
s to clinch or up-turn it and prevent it entering the body of the last with the
accruing disadvantages herein before expressed.
When the socket is made with sides converging towards its mouth as shown,
the leather plug C when forced therein under pressure will expand at its lower
part and be held in position thereby.
Instead of the sole plate D being employed to hold the socket in position the
latter may be screw threaded on its outer surface as shown in Figure 4 or other-
wise serrated or roughened so that upon being forced into the last it will be
held in position thereby.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
5 we claim is :-
-
1. A wood last having one or more recesses on its undersurface, a socket o
thimble of the character described fitting into each recess and a plug of leather
or equivalent material fitting into each socket for the purpose specified.
2. The improvement in wood lasts substantially as described and illustrate
anying drawings.
