Improvements in Lasts for the Manufacture of Boots and Shoes.
JOHN SHARP Pattern Maker 17 Thorngate Street JOHN WILLIAM SHARP,
Engineer 46 Wood Street both of Kettering in the County of Northamptonshire
do hereby declare the nature of this invention to be as follows :—
This invention has for its object improvements in and appertaining to lasts used
in the manufacture of boots and shoes, and relates to improvements in lasts used
and made at the present time.
The object of this or these lasts is to be made to enter a boot or shoe similar to
the human foot. That is to say the said last is made with a joint hinged across the
ball or tread near or as near as is possible to be got to the insole of the boot that
is made on the aforesaid last, and to resist the amount of hammering brought to
bear upon the last by operator in making a boot or shoe to same.
We do not confine ourselves precisely to the cutting of the aforesaid last on the
ball or tread. We cut the aforesaid last so as to give ease in entering a boot or
shoe or free delivery from same. More fully described, the aforesaid last is made
with or without an adjustable block. Where a last is used without an adjustable
block, the cutting of a last is carried from near the ball to the instep of same giving
a vacancy for sufficient moving of the said joint and to give a free delivery of the
last from the boot or shoe, and the instep is fitted with a jointed post to rest on a
clip stop-plate near to the waist of the aforesaid last. Where the adjustable block
is used, the said block is cut lower, that is to say, over and to cover the aforesaid
joint on the ball or tread having a conical pin fitted to the said block and a hole
bored in the forepart of the last to suit the said conical pin in block, and the afore-
said block to be locked in position by means of a spring catch, the same to be
released by the insertion of a key or lever hook.
We are well aware of lasts being made with adjustable insteps and loose heels, or
lasts divided in many parts, but what is new and novel in our present invention is a
last with an hinged forepart near the ball or tread. These lasts may be made in
wood or iron suitable for combination or rivetted work.
