Improvements in or appertaining to Lasting Machines.
A. communication from abroad by THE ROCHESTER LASTING MACHINE
COMPANY, of Rochester, in the State of New York, United States of
America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster & 323 High Holborn, in the
County of Middlesex, Civil 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 :—
This invention relates to lasting machines and has reference moro particularly to
the wipers or blades for turning the leather at the heel or toe down upon the
insole at the bottom of the last, the invention being designed more particularly as
an improvement upon the devices represented in British Letters Patent dated
August 7th 1888 No. 11379 and December 23, 1890 No. 20960 to which patents
reference is hereby made for a general description of the operation of the wipers.
In the accompanying drawings,
Figures 1 and 2 are perspective views of the improved wipers looking at them
from opposite faces.
A indicates the stock or stem to which the blades B B are pivoted by means of a
screw C. The blades B B are each provided with a tail or extension D, which
latter are connected by means of a coil spring E tending to keep the operative ends
of the blades or wipers separated.
F indicates a loop loosely attached at its ends by means of screw G to the blades
or wipers B B near their outer ends, the centre of the loop being located a short
distance in advance of the screw or pivot C of the blades or wipers B.
When the device is moved in the direction of its length as described in the
patents above referred to, the loop F will first strike the projecting edge of the
upper and give to it an approximately circular form, so that by the time that
the blades themselves come in contact with the upper they will find that the
preliminary drawing in of the upper has been completed by the wire, and they will
therefore have to perform merely the function of laying the upper down upon the
insole so as to insure its adhesion to the latter.
The action of this wire or loop upon the upper while the latter is held taut by
the toe pincers is found to give excellent results in practice and has rendered the
machine capable of use on shoes made of patent leather, which, as is well known
is a substance difficult to properly handle by machinery.
By providing the blades with the tails or extensions D one is enabled to connect
the fatter by a single spring and thereby dispense with the use of the separate and
independent springs heretofore used:
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
1. In combination with the stem A, the pivoted blades or wipers and the wire or
loop F substantially as set forth.
2. In combination with the stem A, the blades or wipers B B pivoted thereto,
and the wire F formed into a loop and attached to the blades or wipers near
their ends.
3. The blades or wipers provided with a wire or loop F located slightly in
advance of the pivot of the said blades or wipers.

and provided each with a tail D and a spring E connecting the tails of the blades,
all substantially as shown.
