page_text: LETTERS PATENT to William Edward Gedge, of the Firm of John Gedge
and Son, of No. 11, Wellington Street, Strand, in the County of Middle-
sex, Patent Agent, for the Invention of "IMPROVED PINCERS FOR GAS AND
OTHER PIPES."-A communication from abroad by Jules Chartiez, of 89,
Faubourg St. Martin, Paris, France.
Sealed the 6th July 1865, and dated the 11th January 1865.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge,
at. the Office of the Commissioners of Patents, with his Petition, on
the 11th January 1865.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVED
PINCERS FOR GAS AND OTHER PIPES" a (communication to me from abroad
by Jules Chartiez, of 39, Faubourg St. Martin, Paris, France, to be as
follows:-
The pincers, the subject of this Invention, is intended to obviate the
numerous inconveniences of ordinary pincers and hand-vices, specially when
men have to work where want of room impedes their motions, and in spots
of difficult or perilous access. It may be easily manoeuvred with one hand

page_text: only, which is a great advantage, as will be seen on reference to the accom-
panying Sheet of Drawing (on which the pincers is drawn usual size). It is
composed of a stem A, B, serving for handle; at the point C of this stem is
jointed (as shewn, Figure 2) a part D, E, F, of the shape shewn, Figure 1.
This piece D, E, F, is of less thickness outside than inside the section;
Figure 3 shews the average thickness. The inner face is cut in arcs or
segments of a circle a, b, c, d, e, f, g, h, i, k, of a radius corresponding with
the radius of the various running sizes of pipe on which the pincers is likely
to be used. These surfaces a, b, c, d, e, f, g, k, i, k, are jogged or notched to
assist in holding the pipes. The upper part A of the handle A, B, is round,
and is also notched. The two pieces D, E, F, and A, B, move freely round the
pin C, which serves as their rotation axis. The inner curve of D, E, F, as
well as the position of the parts a, b, c, d, e, f, are calculated so as to embrace
and completely nip pipes of corresponding diameter by simply causing the
handle A, B, to rotate so that its axis passes to about the centre of the
pipe.
Figure 1 shews in red the apparatus holding a pipe in the segment e, f,
such pipe being rather less than an inch in diameter. The running sizes of
pipes will be divided into series, and a special apparatus will be provided for
each series.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Gedge in the Great Seal Patent Office on
the 7th July 1865.
TO. ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11, Welling-
ton Street, Strand, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of January, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said William Edward Gedge, Her special licence that I, the said
William Edward Gedge, my executors, administrators, and assigns, or such
others as I, the said William Edward Gedge, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to
time, and at all times thereafter during the term therein expressed, should

page_text: and lawfully might make, use, exercise and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVED PINCERS FOR GAS AND OTHER PIPES," (a communication
to me from abroad by Jules Chartież, of 89, Faubourg St. Martin, Paris,
France), upon the condition (amongst others) that I, the said William Edward
Gedge, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe 'and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said William Edward Gedge, do hereby
declare. the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Sheet of Draw-
ing, forming part of this Specification, and to the figures and letters of
reference placed thereon :-
The pincers, the subject of this Invention, has for object to obviate the
numerous inconveniences presented by the ordinary pincers, and screw pincers,
or hand vices, especially when the workmen have to perform a difficult job.
This pincers may be worked with one hand only, which is an incontestible
advantage when working in places of difficult or perilous access.
It is com-
posed of a stem or rod A, B, serving for handle; at the point C of this rod is
jointed, as shewn on the Drawing, a piece D, E, F, of the shape shewn,
Figure 3, or modified as shewn, Figure 1. This piece D, E, F, is of less
thickness on the exterior than on the interior; Figure 4 gives an average
section of it. The inner face (Figure 3) carries notched or toothed segments
of a circle or arcs a, b, c, d, e, f, g, h, i, k, of radii corresponding with the
radii of the various running sizes of pipe. The notching of the arcs serves
to facilitate the grasping and holding of the pipes. The upper part A of the
handle A, B, is round, and is also notched or toothed.
The two pieces
D, E, F, and A, B, move freely on the pin C, which serves as their rotation
axis. The inner curve of D, E, F, as well as the position of the parts
a,
b, c, d, e, f, g, h, i, k, are so calculated as to perfectly embrace and nip
pipes of corresponding diameter on simply bringing the handle A, B, by rota-
tion into such a position that its axis passes nearly through the centre of the
pipe. The position of the handle in relation to the piece D, E, F, when
nipping a pipe of a diameter corresponding with the arc e, f, is indicated in
red at Figure 3.

page_text: Figures 1 and 2 shew a lateral and a back view of a modification of my
improved construction of pincers. The inner face of the piece D, E, F,
is. one single and same curved surface, as shewn on the Drawing, and is
notched or toothed. At the end of the rod A, B, serving for handle, is a
piece G, H, also notched, and it is between this latter and the piece D, E, F,
that the pipes are nipped. This arrangement possesses the advantage of per-
mitting the use of one pincers for nipping pipes of no matter what diameter,
provided always that these diameters are comprised within the two limits
imposed beforehand by the dimensions of the piece D, E, F. The position of
the piece D, E, F, in nipping a pipe of small diameter is shewn in blue, and
its position in nipping one of large diameter in red, Figure 1.
In witness whereof, I, the said William Edward Gedge, hath hereunto
- set my hand and seal, this Seventh day of July, in the year of our Lord
. One thousand eight hundred and sixty-five.
