PROVISIONAL SPECIFICATION.
Improvements in or relating to Lasting Pincers.
I, JAMES ALLEN, of No. 25 Willow Bridge Street Leicester in the County of
Leicester Boot, Shoe and General Dealer do hereby declare the nature of this
invention to be as follows:-
This invention refers to improvements in or relating to lasting pincers of the
kind used for pulling over and tacking the uppers of boots and shoes in the process
of lasting them.
The object of this invention is to obviate what is now a serious defect in lasting
pincers in consequence of their breaking across at their weakest point that is to
say; at the neck or pivotal portion between the upper serrated jaw and handle
which, having to be forced through the groove made in the pivotal portion of the
lower jaw or hammer portion while hot, thus it is not in a fit condition to withstand
the strain exerted in pulling the upper of the boot or shoe over on the last.
To avoid this fracture I cause the pincers to be made in two parts, the upper
part or jaw being laid in a groove or recess in the lower part or jaw, and held
therein by a plate of steel let in and secured by screws to the handle and jaw thereof,
which carries a hammer head in the usual manner. The whole is then pivotally
connected by a bolt and screw or lock nut and washer.
Such plate or cap is let in flush with the side and of a shape corresponding with
the pivotal bearing or body of the pincers; whether of a special circular form, or
of the ordinary well known shape. By placing a cap over the two detachable
portions consisting each of a handle, pivotal base and serrated jaw, such cap being
of good steel-the upper jaw can be put relatively with the other in a condition
well calculated to withstand any amount of leverage exerted against the fulcrum
or hammer head in pulling the upper, of a boot or shoe over on the last during the
process of lasting.
This applies in a measure to machine lasting pincers as well as hand, if they are
put together in the manner as before described.
J
The strength of the steel cap or plate lies more particularly in the fact that by
preference it is let in almost, or approximately parallel, in a diagonal line with the
length, foot or hammer head, and jaws of the pincers.
The outer ends of the handles or levers are pointed and pitched in such a manner
that the operator can use them in levering up, or bringing the lining level with the
upper of any narrow toe, before pulling it over.

I, JAMES ALLEN of No. 25 Willow Bridge Street Leicester in the County of
Leicester Boot, Shoe and General Dealer 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 refers to improvements in or relating to lasting pincers of the
kind used for pulling over and tacking the uppers of boots. and-shoes in the process
of lasting them:
That this invention may be well understood I have appended a sheet of drawings
in which
Figure I is a side view of a pair of lasting pincers constructed in accordance
with my invention.
Figure 2, a bottom view of Figure 1.
"Figure 3, a top view of same.
Figures 4 and 5 are views in perspective of the separated arms and jaws of the
pincers.
Figure 6, a flat view of the plate or cap of steel to secure said arms and jaws.
Figure 7 is a representation of one kind of punch the side elevation showing: the
arrangement of the plate or cap in accordance with my invention.
Figures 8 and 9 represent a lower and upper view of the ordinary way of
making various kinds of pincers, punches and the like, and by "broken line" X
the part likely to fracture, or the point where such articles break.
Similar letters of reference are used' to represent like parts in the drawings.
The object of this my invention is to obviate what is now a serious defect in lasting
pincers in consequence of their breaking across at their weakest-poiut, that is to
say, at the neck "see line ✗"Figures 8 and 9 or pivotal portion between the
upper serrated jaw and handle "see Figure 9" which, having to be forced
through the groove made in the pivotal portion "Figure 8" while hot, is thus not
in a fit condition to withstand the strain exerted in pulling the upper of the--boot
or shoe over on' the last.
To avoid this fracture I cause the pincers or the like to be made in two
parts A, B the upper part or jaw A¹ and 6 "see Figure 4," being laid in a groove
or recess in the lower part or jaw B" "Figure 5" and held therein by the
plate of steel C "Figure 6," let in and secured by the screws D and D' in holes
in the handle, and recess in the upper jaw A, this carries a hammer: head E in the
usual manner. The whole is then pivotally connected by a counter sunk screw,
and out F, or may be washer. Such plate or cap C, is let in flush with- the-side
and of a shape to correspond with the pivotal bearing or body of pincers. By
placing such a cap over the two detachable portions, consisting each of a handle,
pivotal base and serrated jaw, (such cap being of good steel,) the upper jaw can
be put relatively with the other in a condition well calculated to withstand any
amount of leverage exerted against the fulcrum or hammer head in pulling the
upper of a boot or shoe over on the last during the process of lasting.
This invention also applies to other kinds of pincers an example of which is
shown in Figure 7 of the accompanying drawings in the form of an instrument
used for punching out button holes constructed in accordance with my invention.
The strength of the steel plate or cap C lies more particularly in the fact that it
is let in almost or approximately parallel, in a diagonal line with the length, foot
or hammer head, and jaws of the article "see Figure 1."
The outer ends of the handles or levers are pointed and pitched in such a manner
that the operator can use them in levering up, or bringing the lining of a boot or
shoe level with the upper of any narrow toe, before pulling over on the last.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the construction of lasting pincers the combination of the upper and lower
parts with a plate or cap secured flush with the said parts in the manner and
for the purpose substantially as described with reference to the accompanying
drawings.
2. The combination with a recessed upper portion fitting the corresponding part
of the lower or hammer portion of pincers and the like secured by steel plate.
3. The combination of parts forming pincers and the like for the purpose and in
the manner substantially as herein described and set forth.
Dated this 5th day of March 1895.
