.
hampton, in the County of Stafford, and Moses Barnard, of Wil-
lenhall, near Wolverhampton, in the County of Stafford, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF DOOR FASTENERS
AND LIKE ARTICLES."
Sealed the 4th October 1872, and dated the 6th April 1872.
PROVISIONAL SPECIFICATION left by the said Matthew Tildesley and
Moses Barnard at the Office of the Commissioners of Patents, with
their Petition, on the 6th April 1872.
We, MATTHEW TILDESLEY, of Penn Fields, Wolverhampton, in the
County of Stafford, and MOSES BARNARD, of Willenhall, near Wolver-
hampton, in the County of Stafford, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF DOOR FASTENERS
AND LIKE ARTICLES," to be as follows:-
This Invention consists, firstly, in arranging the tools used for piercing
and cutting the plates of door bolts, locks, and like articles so that
instead of all the holes in one plate being pierced at one stroke or

page_text: operation the back holes of one plate are pierced at the same time and
operation that the front holes of another plate are pierced. To effect
this operation we fix the tools in the reverse order as at present, that is,
we place the back tools to the front of the front tools and the cutting
tools between the said front and back tools. By this arrangement of
the tools any distance may be given between the front and back holes
by simply altering the gauge against which the plate is pushed instead
of having to use different tools.
And this Invention consists, secondly, in the use of tools for preparing
the ends of necked and solid ended round door bolts, the said tools being
shaped so as to throw the parts (hitherto made at right angles to the
bolt) at angles inclining outwards from the said bolt, and the said tools
are also made to form the said inclined parts round or circular in section.
Bolts made with these tools are neater in appearance and cost less to
finish.
And this Invention consists, thirdly, in arranging the cutting and
punching tools for padlock plates in one piece or fixture so that the plate
is finished at one operation.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew Tildesley and Moses Barnard in the Great
Seal Patent Office on the 5th October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MATTHEW
TILDESLEY, of Penn Fields, Wolverhampton, in the County of Stafford,
and MOSES BARNARD, of Willenhall, near Wolverhampton, in the
County of Stafford, send grecting.
'
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Sixth day of April, in the year of
our Lord One. thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Matthew Tildesley and Moses Barnard, Her
special licence, that we, the said Matthew Tildesley and Moses Barnard,
our executors, administrators, and assigns, or such others as we, the
said Matthew Tildesley and Moses Barnard, our executors, adminis-
trators, and assigns, should at any time agree with, and no others, from

page_text: 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 Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF DOOR FASTENERS AND LIKE ARTICLES," upon the condition
(amongst others) that we, the said Matthew Tildesley and Moses Bar-
nard, our executors or administrators, by an instrument in writing under
our, or one of our, or their, or one of their hands and scals, 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 we, the said Matthew Tildesley and Moses
Barnard, do hereby declare the nature of our 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 Drawings (that is to say):-.
!
Our Invention has for its object, firstly, an improved arrangement
of the cutting and punching tools. used in forming door bolts and like
articles; secondly, improvements in the shape or configuration of the
dies or tools, used in stamping or pressing the ends of necked and solid
ended round door bolts; and, thirdly, in an improved arrangement of
the cutting and punching tools for forming padlock plates; and
consists,―
Firstly, in arranging the tools used for piercing and cutting the plates
of door bolts and like articles so that instead of all the holes in one
plate being pierced at one stroke or operation the back holes of one
plate are pierced at the same time and operation that the front holes
of another plate are pierced. To effect this operation we fix the tools
in the reverse order as at present, that is, we place the back tools to the
front of the front tools, and the cutting tools between the front and
back tools. By this arrangement of the tools any distance may be
given between the front and back holes by simply altering a gauge
against which the plate is pushed, instead of having to use different
tools for different lengths of plate.
And this Invention consists, secondly, in the use of tools for forming
the ends of necked and solid ended round door bolts, the said tools

page_text: while the front of one plate is being punched and squared by the
tools c', etc., the back holes of another are being punched, and the ends
shaped by the tools c, etc., and that thus there is a plate finished at
each operation, with the advantage of making one set of tools do for
more than one length of bolt.
Figures 2 and 3 shew sections through tools for roughing out the
ends of necked and solid ended round door bolts so as to finish them in
tools or dies shaped as in Figure 4 and shewn on plan.
i
Figure 4 shews one of a pair of finishing tools or dies for necked and
solid ended round door bolts. The half of the shape of bolt is sunk
into cach tool or die as will be readily understood. The parts K are
shewn inclining at angles greater than a right angle from the straight
part of the bolt L. They are also shewn circular in section as is illus-
trated by shading lines on finishing tool, Figure 4. By these tools we
are able to make the diameter of the knob about one-eighth of an inch
larger than the iron. The circular and flat parts in the roughing
tools will be made clear in the shading, and the width of the tools is
not important. The dies for making both the necked and solid end
may be formed in one pair of tools, or separate tools may be used for
each, either for roughing or finishing. We use these tools in a steam
stamp.
The tools for forming the plates illustrated in Figure 1 and the
roughing and finishing tools for forming the bolts illustrated by
Figures 2, 3, and 4 are all drawn full size and are for six inch bolts.
Figure 5 shews a plan and sectional elevation of our tools as arranged
for forming padlock plates. They are shewn as arranged for a front
plate. M is the strip or hoop iron from which the plates are to be cut,
and is shewn by dotted lines on plan. N is the bottom tool; O, the top
tools for punching the holes in plate; P, a punch for making a gauge
or recess in side of plate; R, the top tool for cutting out the plate; S, S,
and S¹ the guides or stops; U, the guard or gauge. The method of
using these tools is thus:-The strip or hoop iron M from which the
padlock plates are to be made is first pushed in the direction of the
arrow W to a little beyond the point X, and the side held against the
guides or stops S, S. The top tools o, etc., and P and R then descend,
the tools.o, etc. punching all the holes, the tool P cutting or punching
a piece, out at the side, and the tool R curving the end of the strip

page_text: at X. The strip M is then pushed forward, and the recess or gauge
formed by the tool P is held against the gauge U, and the side of the
strip M. held against the guides S, S, and S¹ as shewn on the Drawing.
The upper tools o, etc. P and R again descend, when the plate having
the holes already punched in is cut or stamped out complete by the
tool R. The tools o, etc. and P prepare another plate at the same time.
The tool P and the gauge U have a "lead" given to them sideways, to
facilitate putting the recess in the strip against the gauge U. The
method of forming the gauge with a punch P and gauge U may bc
varied to suit the shape of the plate, as for instance if the plate is
straight sided the punch and gauge must be put more forward or
backward, so as to cut from the corner of the plate, and may be of
different shape.
In each case the faces only of the tools are shewn, as the novelty
consists therein, and a competent tool maker will be able to form the
other parts of his tools to suit the machine in which he may wish to
use them.
Having now particularly described and ascertained the nature of our
said Invention, and in what manner the same may be performed, we
declare that we claim, the use of the improved tools as set forth and as
constituting "Improvements in the Manufacture of Door Fasteners and
like Articles," and as various modifications follow obviously from this
description of our Invention we do not limit ourselves to the exact
arrangements as shewn, but claim such arrangements and modifications
as are in harmony with the general description of this our Invention.
In witness whereof, I, the said Matthew Tildesley, on behalf of
myself and the said Moses Barnard, have hereunto set my hand
and seal, this Second day of October, in the year of our Lord
One thousand eight hundred and seventy-two.
