A communication by THE GOODYEAR SHOE MACHINERY COMPANY, of Portland,
in the County of Cumberland and State of Maine, 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, 118 New Street, Birmingham
in the County of Warwick and 322 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 perforined, to be particularly described and ascertained
in and by the following statement :-
The invention relates to an improvement in lasting tools having a pivoted
fulorum, and it consists in pivoting to the usual form of lasting pincers a rocking
fulcrum and a means for operating the same, preferably a handle or lever.
The object of the invention is to provide a movable fulcrum having a boaring
surface which when in use rests against the side of the upper when mounted on the
last, in such manner that the edge of the upper may be readily gripped by the jaws
of the pincers, and tightly drawn laterally, over the inner sole on the last.
The invention is illustrated in the accompanying drawings forming a part of the.
specification and on which:
Figure 1 is a side view of the tool or pincers in use, showing the last and upper
in section.
Figure 2 is a top plan view.
Figure 3 is a section on line - Figure 1.
Figure 4 shows the ordinary tool as commonly used.
Like letters of reference indicate corresponding parts in the different views.
A, represents one jaw of the tool and its lever or handle, and B, is the other jaw
with its handle. They are pivoted to each other at their shanks at a, and the inner
faces of the jaws are corrugated, roughened or serrated in the usual manner.
C is the movable fulcrum. It is pivoted in the present instance at its upper end
to the lower jaw of the tool at a', and at the lower end to a toggle D, at a 3. The
fulcrum C, is curved on its inner side, and is of substantially the configuration of.
the side of the last.
The toggle D is a curved lever or arm, and is pivoted at. its front end at a 3, to
the movable fulcrum C, at the lower end of the latter, and at its rear it is pivoted
at a 2, to the operating arm or lever E. The short arm of the arm or lever E is
pivoted to the toggle D, and has an upward curved portion, and at the apex thereof
ia pivoted at a 4, to the handle or operating lever of the jaw B.
A hammer or driver G is tapped or otherwise secured on top of the tool and is
to be used for driving tacks, etc., in a well known manner.
The movable fulcrum C, is shown as bearing against the side of the upper on
the last, in, full lines in Fig. 1 and as withdrawn therefrom when not in use, as
shown in dotted lines.
The lower end of the fulcrum C, may be bifurcated, and the front end of the
toggle D, may be pivoted in said bifurcation; or the toggle may be bifurcated and
the lower end of the fulcrum C, be pivoted therein. It is evident that either
construction would produce the saine result, and the structures just described are
mechanical equivalents.

page_text: The rear end of the toggle D, is pivoted to the operating lever or handle E in
the same manner.
In operation, the jaws grip the edge of one side of the upper, and the carved
edge of the fulcrum C, rests against the upper on the opposite side of the last.
The handles or levers of the two jaws as well as the lever or handle E, are
pressed towards each other by the operator as woll shown in Fig. 1, and the upper
is drawn in close contact to or parallel with the bottom of the last over the insole
mounted thereon.
The fulcrum C, resting against the side of the last with the upper mounted
thereon greatly increases the purchase of the tool and a boot or shoe is lasted with
more ease, in a shorter time and with much better results than with the ordinary
tool.
The tool is especially adapted for lasting the shank of a boot or shoe, although
it is also capable of use in lasting the ball or the sides of the heel.
It is particularly valuable and effective in lasting the shanks, where the heel and
toe are lasted by machine, as is customary in what is known to the trade as "the
Copeland rapid laster:"
As the sections of the upper are drawn over the insole successively, they are
secured by tacks or equivalent meaus in the usual way.
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. A lasting tool having gripping jaws and their operating handles or levers,
and a movable fulcrum pivoted to one of said jaws, and adapted to bear against
the side of the last, and an independent means for operating the same, substantially
as described.
2. A lasting tool having gripping jaws and operating handles or levers therefor,
a movable fulcrum pivoted to one of said jaws and adapted to bear against the side
of the last, a toggle arm or lever pivoted to the lower end of the movable fulorum,
and an operating lever for the toggle and fulorum, substantially as described.
3. A lasting tool having gripping jaws and operating handles or levers therefor,
a movable fulcrum pivoted to the lower jaw, and adapted to bear against the side
of the last, a toggle arm or lever pivoted to the lower end of the fulcrum and a
lever for operating the toggle and fulcrum, substantially as described.
4. A lasting tool having gripping jaws and operating handles or levers therefor,
a movable fulcrum pivoted to the lower jaw and adapted to rest against the side
of the last, a toggle arm or lever pivoted to the lower end of the fulcrum, and an
independent lever or arm, pivoted to the toggle arm, and to one of the handles or
levers of the jaws, substantially as described.
