JOHN WILLIAM SHARP Engineer 24 Thorngate St. Kettering, Northamptonshire
do hereby declare the nature of our invention for IMPROVEMENTS IN IRON JASTS
to be as follows:-
This invention relates to a Last cast in two or three parts.
In carrying out our invention we adopt as follows,
In place of a loose block we adopt a loose heel the joint of the said loose heel
and backpart of the last being shaped & fitted in the form of a double O. G., or
hollows and rounds. Inside of loose heel a recess is cast, there is also cast at the
back part of the last a lug, the said lug being fitted to recess in loose heel allowing
the loose heel to rest on the back part of the said last thus preventing the afore-
said loose heel from moveing sideways or backwards.
A hole being bored through the back of the loose heel and through the aforesaid
recess and into the lug cast on the back part of the aforesaid last into which a
slideing bar is fitted, at the end of the said bar is attached a spiral or any other
suitable spring for the purpose of locking the aforesaid heel to the back part of
the last.
To remove the boot after being made on the said last a small lever is used which
is passed up the hollow part of the loose heel and to the end of the slideing bar;
the said lever being brought backwards thus forceing back the slideing bar and
pressing on the spring liberateing the loose heel from the slideing bar and allowing
the boot to be drawn freely off the last, the said loose heel being left in the boot
thus preventing the disarrangement of stiffener or strain on any part of the upper,
the loose heel is then drawn from the boot.
In case the said boot is to be again drawn on to the said last, the loose heel is
again placed in the heel part of the boot the boot is then drawn on the last, the
loose heel thus pressing on and driveing back the slideing bar until the heel is
brought into position, the spring thus acting upon and forceing the slideing bar
into hole in loose heel and locking same.
In the forepart of the aforesaid last a O. G., or hollow and round dovetail is
cast to which the toepart is fitted, thus allowing any required shape of toe to be
attached to the aforesaid last and held in position by a similar slideing bar and
spring locking same as in the aforesaid heel and back part of last.

page_text: We EDMUND NEWBERRY Engineer 70 Northall St. Kettering and JOHN
WILLIAM SHARP Engine Fitter, 24 Thorngate St. Kettering in the County of
Northampton do hereby declare the nature of our invention for IMPROVEMENTS IN
IRON LASTS 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 a Last cast in two or three parts.
In carrying out our invention we adopt as follows,
In place of a loose block we adopt a loose heel, the joint of the said loose heel
and back part of the last being shaped & fitted in the form of a double O. G., or
hollows and rounds inside of loose heel a recess is cast there is also cast at tho
back part of the last a lug, the said lug being fitted to recess in loose heel, allowing
the loose heel to rest on the back part of the said last; thus preventing the
aforesaid loose heel, from moveing sideways, or backwards, a hole being bored
through the back of the loose heel, and through the aforesaid recess and into the
lug, which is cast on the back part of the aforesaid last, into which a slideing bar
or poppit is fitted, at the end of the said slideing bar or poppit is attached, a spiral
or any other suitable spring, for the purpose of locking the aforesaid heel to the
backpart of the last. To remove the boot after being made on the said last a
small lever is used which is passed up the hollow part of the loose heel and to the
end of the slideing bar or poppit, the said lever being brought backwards, thus
forceing back the slideing bar or poppit and pressing on the spring, liberating the
loose heel from the slideing bar or poppit and allowing the boot to be drawn freely
off the last, the said loose heel being left in the boot; thus preventing the dis-
arrangement of stiffener or strain on any part of the upper; the loose heel is then
drawn from the boot.
In case the said boot is to be again drawn on the aforesaid last, the loose heel is
again placed in the heel part of the boot, the boot is then drawn on the last the
loose heel thus pressing on the slideing bar or poppit and driveing back slideing
bar or poppit until the heel is brought into position, the spring thus acting
upon, and forceing the slideing bar or poppit into hole in loose heel, and locking
same.
In the forepart of the aforesaid last a dovetail is cast, to which the toepart is
fitted, thus allowing any required shape of toe to be fitted to the aforesaid last
and held in position by a similar slideing bar or poppit and spring locking same as
in the aforesaid heel and backpart of last.
In conjunction with the aforesaid last we adopt a regulateing instep made of any
suitable material preferable of brass, which is fitted to the last, by hinge or joint,
the aforesaid instep when the boot is made is then liberated allowing same to
close, on to the body of the last, thus giving ease when taking off elastic or spring-
Bide boots.
Haveing thus fully described the nature of the said invention and incidently
intimated in what manner the same is to be performed we will now proceed by

page_text: reference to accompanying drawings to further and particularly describe and
ascertain in what manner the same is to be carried out in practice that is to say
Fig. 1., is side elevation of our "Improved last complete."
Fig. 2., is top view of last complete.
Fig. 3., represents side elevation shewing dovetail on changeable toe.
Fig. 4., represents sectional view of the body part of last shewing regulateing
instep & slideing bar or poppit, buffer, & O. G's or hollows and rounds.
Fig. 5., represents detail side elevation of loose heel, shewing back chamber or
recess and O. G's or hollows and rounds.
Fig. 6., is front sectional elevation of same.
Fig. 7., represents bottom sectional elevation of Fig. 3.
Fig. 8., represents bottom sectional elevation of Fig. 4.
Fig. 9., represents bottom sectional elevation of Fig. 5 & 6.
Fig. 10., represents an elastic or springside boot partly withdrawn from our
improved last with regulateing instep closed.
A. is the body or centre part of last. B. is the loose heel; secured to the body
or centre part of last A. by means of slideing bar or poppit a, a¹ spring for the
purpose of forceing back slideing bar or poppit a, into hole b. of heel B, a boss or
lug cast on last to receive slideing bar or poppit a, a³ dovetail to which changeable
toe C is fitted. a regulateing instep attached to body of last A., by joint or hinge a³,
a catch, fitted to regulateing instep a', a spring for holding catch as, in position
during operation as is recess cast in body of last A. to receive catch aⓇ & spring a
a shewing a view of double O. G.s or hollows and rounds a¹0 is recess cast in last
to receive stand, pivot, or upright, all is buffer preferable of india rubber, which is
fitted in a hole bored in the backpart of body of last Fig. 4, for the purpose of
resisting the great pressure brought to bear upon the loose heel of the last during
operation & thus preventing breakage thereof. 61 chamber cast in back part of
heel B., to receive lever for the purpose of liberateing slideing bar or poppit a,
20. G's or hollows and rounds, which fit the corresponding O. G's, a on body of
last A., 63 recess cast in loose heel B. to receive boss or lug a³, C fig. 3 shews side
elevation of changeable toe part of last.
Haveing thus described our improvements and the best means we are acquainted
with for carrying same into effect we would have it understood that we do not
confine ourselves to the precise details shewn & described as these may be varied
without departing from the peculiar character of the invention but what we do
claim is
1st The general arrangement and construction thereof, substantially as illustrated
& set forth & for the purpose hereinbefore described & represented in the
accompanying drawings.
2nd The combination of last with loose heel, changeable toes, regulateing instep,
catch, & for the purpose described.
3rd The combination of slideing bars or Poppits & for the purpose described.
4th The combination of buffers double O. Gs or hollows and rounds as illustrated
and shewn in accompanying drawings & for the purpose described.
