Ax IMPROVED PORTABLE PUNCH FOR PUNCHING METALS
Year: 1869

page_text: LETTERS PATENT to Edward Craddock, of No. 8, Camberwell New
Road, in the County of Surrey, Engineer, for the Invention of "Ax
IMPROVED PORTABLE PUNCH FOR PUNCHING METALS."
Scaled the 18th July 1869, and dated the 15th January 1869.
PROVISIONAL SPECIFICATION left by the said Edward Craddock at the
Office of the Commissioners of Patents, with his Petition, on the
15th January 1869.
I, EDWARD CRADDOCK, of No. 8, Camberwell New Road, in the
5 County of Surrey, Engineer, do hereby declaro the nature of the said
Invention for "AN IMPROVED PORTABLE PUNCH FOR PUNCHING METALS," to be
as follows:-
This improved portable punch for punching metals is made as
follows: To a suitably shaped body made of metal are connected two
O metallic arms, one of them being fixed to the upper part of the body (or it

page_text: may be cast or made in one piece with it), and the other which is movable
is secured to a quick threaded screw passing through the centre of the
body of the apparatus, to the lower extremity of which screw a punch is
firmly secured. At the outer end of each arm is fitted a jaw or joint
made capable of revolving, and in each jaw or joint a stud or nut is
place, which is also made capable of revolving. A "screw" or circular
piece of steel, one half of which is threaded as a right-hand screw and
the other half as a left-hand scrow, is passed through the stud, one end
heing so formed as to allow a handle or key to be fitted thereon to
operate the screw. On the "screw" being turned by the handle or key
the double action of the "screw" causes the movable arm to approach
to or recede from the other arm, and causes the punch to be forced down
by means of the quick threaded screw secured to the movable arm and
to it, thereby causing the desired punch or perforation to be made in the
metal submitted to the operation. In the lower part of the body of
the apparatus a spaco or cavity is formed to admit the metal (such, for
example, as a boiler plate or sheet) under the punch to be operated on.
In the lower part of this space is fitted a small bed or die, having a hole
in the centre immediately under the punch, through which the pieces
of metal as they are punched out drop down out of the way.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Craddock in the Great Seal Patent Office
on the 15th July 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
CRADDOCK, of No. 8, Camberwell New Road, in the County of Surrey, 2
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of January, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-second year of Her reign, did, for Herself, Her heirs and succes- 3
sors, give and grant unto me, the said Edward Craddock, Her special
licenco that I, the said Edward Craddock, my executors, administrators,
and assigns, or such others as I, the said Edward Craddock, my

page_text: executors, administrators, and assigns, should at any time agres
with, and no others, from time to time and at all times thereafter
during the term therein expressed, should 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 Inven-
tion for "Ar IMPROVED PORTABLE PUNCH FOR PUNCHING METALS," upon the
condition (amongst others) that I, the said Edward Oraddock, my
executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describo
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 Edward Craddock, do hereby
declare the nature of the said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement in writing, and on reference being had to tho
accompanying Sheet of Drawings, that is to say :-
This improved portable punch for punching metals is made as
follows: To a suitably shaped body made of metal are connected two
metallic arms, one of them being fixed to the upper part of the body (or it
may be cast or made in one piece with it), and the other which is movable
is secured to a quick threaded screw passing through the centre of the
body of the apparatus, to the lower extremity of which screw a punch is
firmly secured. At the outer end of cach arm is fitted a jaw or joint
mado capable of revolving, and in each jaw or joint a stud or nut is
placed, which is also made capable of revolving. A "scrow or circular
picce of steel, one half of which is threaded as a right-hand screw and
the other half as a left-hand screw, is passed through the studs, ono end
being so formed as to allow a handle or key to be fitted thereon to
operate the screw. On the "screw" being turned by the handle or key
the double action of the "screw" causes the movable arm to approach to
or recede from the other arm and causes the punch to be forced down
by means of the quick threaded screw secured to the movable arm
and to it, thereby causing the desired punch or perforation to be made
in the metal submitted to the operation. In the lower part of the
body of the apparatus a space or cavity is formed to admit the metal

page_text: plate to be operated on under the punch. In the lower part of this space
is fitted a small bed or die having a hole in the centre immediately
under the punch, through which the pieces of metal as they are punched
drop down out of the way.
Such being the nature and object of my said Invention for "An
Improved Portable Punch for Punching Metals," I will now proceed to
describe more in detail the manner in which the same is to be or may
be performed or carried into practical, and in order that the same
may be distinctly understood I have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures
and letters of reference corresponding with those in the following
explanation thereof, that is to say :-
Figure 1 is a plan, Figure 2 a side elevation, Figure 3 a front
elevation, and Figure 4 a section of my improved portable punch.
a is the metal body, to which are connected two metallic arms b, bª, 1
one of them b¹ being fixed to the upper part of the body a, and the
other which is movable is secured to a quick threaded screw c passing
through the body a, at the lower extremity of which screw a punch dis
firmly secured. At the outer end of each arm is fitted a jaw e capable
of revolving, and in each jaw or joint a stud or nut fis placed, which
is also capable of revolving. A screw g, one half of which is threaded
as a right-hand and the other half as a loft-hand screw passes through
the studs f, one end of the same being so formed as to allow a handle or
key h to be fitted thereon to operate the screw 9. In the lower part of
the body a a space or cavity i is formed to admit the metal plate under
the punch, and in the lower part of the space is fitted a small die or
bed j, having a slightly tapering hole k in the centre and immediately
under the punch d, through which hole the pieces of metal as they are
punched drop down out of the way.
Having now described the nature and object of my said Invention for
"An Improved Portable Punch for Punching Metals," together with the
manner in which the same is to be or may be performed or carried into
practical effect, I would remark in conclusion that I claim as my In-
vention, the improved portable punch for punching metals, substantially
as herein-before described and illustrated on the accompanying Sheet of 8

page_text: Drawings, or any mere modification or imitation thereof acting in the
same or a similar manner.
In witness whereof, I, the said Edward Craddock, have hereunto
set my hand and seal, this Fourteenth day of July, in the year
of our Lord One thousand eight hundred and sixty-nine.
