PROVISIONAL SPECIFICATION.
Improved Method of Constructing Pincers, Nippers, Hand Vices, and
like Tools and Parts of same.
I, THOMAS RICHARDSON ELLIN, of 4, Eyre Lane, City of Sheffield, Manufac-
turer, do hereby declare the nature of my invention to be as follows:-
My invention relates to a method of constructing, pincers, nippers, pliers,
hand vices and similar nipping and gripping devices or implements, or the jaw
portions of such tools from sheet metal, preferably steel.
It consists in cutting out a suitably shaped strip or blank from suitable
metal, for example sheet steel, and bending it transversely on to or towards
itself in such a way as to produce the desired configuration.
For example in the construction of a wire cutting nipper, I cut out from the
sheet metal a blank with two corresponding wings and the centre portion of a
suitable shape to give the desired form of the jaws and joint.
I then fold it transversely, so that the two wings may coincide with one
another, and may be formed into a suitable handle, whilst the configured centre
parts of two such blanks may be assembled together at a suitable joint, and
the jaws pressed or otherwise formed to suit the required purpose.
When I construct the jaw portion only of such tools, I cut out the blank with
short corresponding ends, and fold it together as before described, but as these
short ends do not form the actual handles, their configuration and the position
of the joint require to be modified accordingly.
The chief advantages obtained by this process are, dispensing with the usual
welds, and liability to overheat the material, and also the production of a
stronger article.
Improved Method of Constructing Pineers, Nippers, Hand Vices, and
like Tools and Parts of same.
I, THOMAS RICHARDSON ELLIN, of 4. Eyre Lane, City of Sheffield, Manufac-
turer, 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:-
My invention relates to a method of constructing pincers, nippers, pliers,
hand vices and like tools, or the jaw portions of such tools or implements from

page_text: sheet metal, such metal being preferably steel, and of varying thickness if
desired. It consists in first cutting out or producing a suitably shaped strip or
blank from the material, and by bending it transversely to produce the desired
configuration of the tool itself, or one half of same, or of the jaw portion of such
tool or implement.
A number of tools produced by this method are illustrated in the annexed
drawings.
Figs. 1 & 2, represent a pair of nippers made under my invention, Fig. 3, is
the blank for the jaws.
Fig. 4, represents the jaws of a pair of pliers with the central space filled in,
and the blank.
Fig. 5, represents a pair of gas-pliers, and edge view of same, and Fig. 6 the
blank for the jaws.
Fig. 7, represents a pair of nippers or pliers, and Fig. 8 is the edge view of
same.
Fig. 9, is the blank used in Fig. S, the extreme ends being removed for want
of space.
Fig. 10, two views of pliers made entirely from two of the blanks shown in
Fig. 11.
Fig. 12, a pair of pliers, and edge view of the jaws made from two blanks as
Fig. 13.
Fig. 14, the two jaws of a hand vice, made from blanks shown in Fig. 16.
Fig. 15, the edge view of Fig. 14.
In carrying out my invention in the construction of a cutting nipper for
example as shown in Figs. 1 and 2, I cut from a piece of flat steel, two blanks
of the shape shown in Fig. 3, both of which I fold transversely across the centre,
so that the two wings A and A³, may coincide with each other, the two semi-
circular projections B1 and B2, forming the joint pieces are held together by
the pin C, and the projection 1), forms the cutting part.
The wings A and A2, are pin jointed to handles E, which are made from
sheet metal folded longitudinally in the manner described in my Patent
No. 1406586 and pin jointed at F, forming a toggle joint, the action of which
needs no further explanation.
In Fig. 4, I show a pair of jaws of similar construction to Fig. 1, but as these
are intended to grip the object I fill up the central space between the folded wings
by inserting a metal block G, secured by rivets or the like, and to produce jaws
of this form, I use blanks of the configuration shown.
In constructing gas pliers such as those shown in Fig. 5, the jaw parts are
produced from blanks as shown in Fig. 6, folded in the same manner as herein-
before described, these and the handles are assembled to form the joint, and
secured by the fulcrum pin H; the wings A1 and A2, being secured to the
handles, and the jaws being bent to make them coincide.
In this case the joint pin H, passes through eight thicknesses of metal.
The pliers shown in Figs. 7 and 8, are formed from two blanks shown in
Fig. 9, the handles being flat and either rivetted, brazed or welded together as
preferred, while in those shown in Fig. 10 with a hollow handle, the blank
Fig. 11, is formed with one end A2 to make the handle, and a short end A¹,
which is carried down into the hollow of the handle, to add to the strength of
the joint and adjacent parts.
A very simple pair of pliers is shown in Fig. 12, made from two blanks as
Fig. 13 folded into a somewhat circular shape for the jaws J, and the fulcrum
pin F, passed through the parts B1 and B2, of both halves as shown.
Figs. 14, & 15, are two views of an unfinished hand vice made from two
blanks similar to Fig. 16, by folding the blanks centrally to the desired form
as seen in Fig. 15. For some purposes the space K, in the jaws J, may be left
open, or if preferred it may be filled with any desired facing block, plain,
roughed or serrated, to suit its intended purpose."

page_text: It must also be understood that when a pair of jaws only are constructed on
this principle they may be combined with handles of any suitable construction;
also that although in Fig. 5, the short wings or ends A & A are shown secured
to the inside of the handle, they may be arranged and secured to the outside
of the handle when desirable.
By this novel method of constructing the tools hereinbefore mentioned or the
jaws only of same, I dispense with the usual welds and the liability to damage
the material by overheating in that process, and I also produce a cleaner made
and stronger article.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1-Constructing the jaw parts of pincers, pliers nippers and like tools, either
separately or in combination with their handles; from suitably shaped blanks,
by folding each blank transversely upon itself as herein before described, and
shown in Figs. 1 to 13 inclusive.
2-A handvice, having its jaws and legs made from two blanks of suitable
form, folded transversely as herein before described and shown in Figs. 14,
15, 16.
