like Nipping and Gripping Tools.
I, THOMAS RICHARDSON ELLIN of Rockingham Street Sheffield in the County of
York Manufacturer do hereby declare the nature of my said invention for AN IMPROVED
METHOD OF CONSTRUCTING PLIERS, PINCERS, AND OTHER LIKE NIPPING AND GRIPPING
TOOLS, to be as follows:-
My invention of an improved method of constructing pliers and other like nipping
and gripping implements is intended to make such tools lighter, handier, and more
durable than those made by the present methods of forging or casting.
In carrying out my invention in the construction of a pair of pliers, for example
such as are used by gas fitters, I make each side of the pliers by punching a blank
somewhat resembling the letter Y from sheet steel or Iron of suitable thickness. I
then bend the shank, or hollow it longitudinally so as to fit the hand comfortably, the
two top parts are then brought nearly close to each other; the space between being
just sufficient to admit one side of the jaw of the other part.
When the two parts are thus put together, they are secured by a centre pin in the
usual manner.
Grooves are usually made in the jaws of gas fitters pliers for taking hold of piping
and similar round work, and the gripping power of such parts is considerably increased
by my method of construction.
In making a double handled pipe wrench or spanner, I make one part or side out
of sheet steel, bent round in the manner before described, and the other part I prefer
to make solid and of thicker material and place it between the two sides of the part
made from sheet steel, and secure the two parts by a fixed or a removeable pin or
screw passed through them. The space between the underside of the projecting jaw
of the central or solid part, and top edges of the shorter bent sheet steel (or iron) side,
forms the mouth of the spanner, and it may be left plain or be serrated as desired.
Dated the 28th day of October 1886.

like Nipping and Gripping Tools.
I THOMAS RICHARDSON ELLIN of Rockingham Street, Sheffield, in the County of
York, Manufacturer 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 of an improved method of constructing pliers, pincers, and other
like nipping and gripping tools, has for its object to make such implements
lighter handier, and more durable, than such tools as at present made by the processes
of forging and casting.
And in order that my invention may be clearly understood I annex a sheet of
illustrative drawings, representing some pliers and similar tools made according to my
invention; similar letters of reference indicate similar parts in any of the figures in
which they occur.
Fig. 1, represents a cut out blank of Steel from which the pliers shown in Fig. 2,
are made.
Fig. 2, a pair of Pliers, side and edge views.
Fig. 3, two views of a pair of nippers.
Fig. 4, two views of a pair of cutting pliers.
Fig. 5, two views of a gasfitters pliers.
Similar letters of reference indicate similar parts throughout the several views.
In making a pair of pliers similar to those shown in Fig. 2, I first punch out two
blanks such as shown in Fig. 1, preferably from steel increasing in thickness in its cross
section, to the side from which the head or jaws are formed. The part A, is to form
the handle, and the parts B, B, are to form the jaws. I then bend the part A,
ongitudinally, so as to form a semitubular handle, the outside being round, of a good
size to fit the hand comfortably, and the inside being hollow or concave.
The two parts B, B, are then pressed nearly close together but so that one of the
parts B, of the other similarly closed half plier may be passed between them as shown
in the edge view Fig. 2; when the two halves are thus placed in position they are
secured by a strong centre pin C, in the usual manner, forming an axis upon which
the two halves open and close.
The two parts B, which when nearly closed form one jaw may be simply held apart
by a small washer (as shown in Fig. 2) placed between them and secured by a rivet,
or a making up piece of larger size, to fill up the entire space, may be secured in like
manner between the parts B.
If the pliers are made with a toothed recess or hollow D, for gripping round objects
(such as gas pipe for example) my method of construction which separates the gripping
parts into four faces instead of the usual two, gives a much firmer grip upon the object

page_text: than can be obtained with two faces of equal width the handles also being hollow or
semitubular, can be made much larger so as to fill the hand comfortably without adding
to the weight of the tool.
In making the nippers or cutting tools as Fig. 3, the jaw pieces B, are bent back
so as to form supports, upon which the blades E, are secured.
In making the cutting pliers Fig. 4, in which both the jaw pieces of one half are
passed between those of the other half, instead of as before described a piece is cut
out of each jaw so as to form a recess, the corresponding portion on each jaw, marked F,
is bevilled so as to form a cutting edge, similar in form to those in general use.
The Pliers, or gripping tool, such as shown in Fig. 5, and which are particularly
adapted for gripping pipes and similar round work, have only one jaw made according
to my invention; this part G is made from a blank, punched out of plate steel in a
similar manner to that shown in Fig. 1, but shaped more like the letter Y.
The hooked part I, is solid and is made either by forging it from the bar, or by
punching it out of the desired thickness of plate.
The part G, is bent, or doubled, or folded so as to allow the part I, to work freely
between the jaws B, which are preferably serrated or toothed as shown, and the two
parts may be secured together by a removable pin or screw H as shown, so that the
opening between the jaws may be adjusted in size for which purpose the part I, is
provided with a series of pin holes.
Although I have described the jaws of the various tools as being composed of two
sides held apart in various ways, the said jaws may (if it be found desirable) be
welded or brazed together so as to form a solid jaw.
I am aware that prior to my invention blanks of various articles have been punched
out of Sheet Steel, also that articles have been made with hollow or partly hollow
handles, I therefore do not claim such operations broadly, or the manner in which
they have been carried out in the manufacture of other tools or articles.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim,
:-
1-A nipping or gripping tool made from two Y shaped blanks of sheet steel or
other suitable metal, so folded as to form the various parts of the desired tool, and
having a box-joint of four thicknesses of metal substantially as described and shown
in Figs. 1. 2. 3. 4. of the drawings.
2-A nipping or gripping tool one half being made from a blank of sheet steel or
other suitable metal, so folded as to form the various parts required, and the other
half made solid, or not folded, substantially as described and shown in Fig. 5 of the
drawings.
