IMPROVEMENTS IN LASTS AND PILLARS OR SUPPORTS FOR THE SAME
Year: 1885

page_text: I JOHN EDWARD BARRACLOUGH ARMYTAGE of Victoria Foundry Stanningley
near Leeds in the County of York, Iron Founder, do hereby declare the nature of
said invention for "IMPROVEMENTS IN LASTS AND PILLARS OR SUPPORTS FOR THE
SAME" to be as follows:-
Hitherto that part of the pillar used for supporting lasts, which is inserted into
the socket or hole in the last has generally an oblong rectangular form.
By the ordinary mode of producing or casting the holes, in the lasts with
ordinary cores no regularity of size or shape could be attained, so that the two
parts (pillar and hole or socket) were not sufficiently uniform in size and shape to
come together and fit.
)
The last and pillar though capable of readily being separated should when
together form a firm base for the shoemaking operation; that is to say; 'that they
should fit so that hammering would not cause any movement or rocking of the last
on the pillar.
'
According to my improvements I make the pillar of cast iron, and by preference
oval at the point to be inserted into the last. The pillars being formed of cast iron
are much more cheaply made and with absolute certainty of fit.
The socket or hole in last is formed by employing a metal chill instead of an
ordinary core; the chill may be the pillar on which it is to be used."
The instep chill of last is placed in the mould and the metal pillar chill firmly
rammed close up to such instep with a thin contraction packing (which may be of
paper or other combustible material), between them. On the moulding of the last
being completed, and the pillar in position, the metal is run in. The packing
being removed by burning the hole or socket is a perfect fit to the pillar when cold,
dispensing with any further labour in obtaining such fit.
The instep chill is hollowed out at small end to suit form or pillar.
Any number of lasts with holes or sockets exactly the same size may be cast in
the above described manner, all such holes or sockets being perfect fits to the
pillar.

I, JOHN EDWARD BARRACLOUGH ARMYTAGE of Victoria Foundry, Stanningley
near Leeds in the County of York, Iron Founder, do hereby declare the nature of
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Hitherto that part of the pillar used for supporting lasts, which is inserted into
the socket or hole in the last has generally an oblong rectangular form.
By the ordinary mode of producing or casting the holes in the lasts with
ordinary cores no regularity of size or shape could be attained, so that the two
parts (pillar and hole or socket) were not sufficiently uniform in size and shape to
come together and fit.
The last and pillar though capable of readily being separated should when
together form a firm base for the shoemaking operation that is to say; that they
should fit so that hammering would not cause any movement or rocking of the last
on the pillar.
Fig. 1 is a side elevation and Fig. 2 a plan of last constructed according to my
improvements.
In accordance with my improvements I make the pillar a of cast iron and by
preference oval as shewn at 6 Fig. 2 to be inserted into the last c
The pillars being formed of cast iron are much more cheaply made and with
absolute certainty of fit.
The hole d in the last is formed by employing a metal chill instead of an
ordinary core; this chill may be the metal pillar a on which the last c is to
be used.
The instep chille is placed in the mould and the metal pillar chill a firmly
rammed closely up to such instep chill e.
These may have a thin contraction packing between them which may be of
paper or other combustible material.
On the moulding of the last c being completed and the pillar or chill a in
position the metal is run in in the usual way. The packing being removed by
burning, the hole d is a perfect fit to the pillar a when cold dispensing with any
further labour in obtaining such fit.
The instep chill e is hollowed out at small end f to suit form of pillar a.
Although I have stated that a packing may be used between the small end of
the instep chille and the pillar chill a, it is not absolutely necessary that this
should be used.
18
In very small sizes of lasts where the metal round the hole at the sides
necessarily very thin I employ an ordinary core instead of the metal pillar chill a
in combination with the instep chill e.
Any number of lasts with holes or sockets of the same size may be cast in the
above described, manner, all such holes or sockets being perfect fits to the pillars.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
Lasts constructed or moulded in such a manner that when cast they are perfect
fits to their pillars and instep pieces, thus forming a firm base for the shoemaking
operation, substantially as herein set forth.
