IMPROVEMENTS IN THE CONSTRUCTION OF DOOR BOLTS AND OTHER FASTENINGS
Year: 1875

page_text: LETTERS PATENT to Matthew Tildesley, of Tettenhall Wood, near
Wolverhampton, in the County of Stafford, Gentleman, for the
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF DOOR BOLTS AND
OTHER FASTENINGS."
Sealed the 29th June 1875, and dated the 1st January 1875.
PROVISIONAL SPECIFICATION left by the said Matthew Tildesley at the
Office of the Commissioners of Patents, with his Petition, on the
1st January 1875.
I, MATTHEW TILDESLEY, of Tettenhall Wood, near Wolverhampton,
in the County of Stafford, Gentleman, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF DOOR
BOLTS AND OTHER FASTENINGS," to be as follows:-
The chief object of this Invention is to construct the articles named
in the title in such a manner that old bale ties or hoops or other narrow
scrap iron may be used for the material composing the said articles, and

page_text: thus considerably reduce their cost. The hollow bolt or rod hereafter
mentioned may however be made from new iron when preferred.
The first part of my Invention refers to the construction of door bolts,
and consists as follows:-I form the bolt plate by placing two strips of
iron edge to edge so as to form one wide plate. I place other strips
of iron, preferably three, but more or less if required, across the two
strips before mentioned, and in positions as required to suit the staples.
I form the staples of two thicknesses of iron, and form the ends so as to
leave an oblong rivet or rivets with the necessary shouldering. The
staples are bent to the required form, and the rivets passed through
openings prepared for them in the cross strips and plate already
mentioned. The staple rivets thus hold together the plate, cross strips,
and staples. One staple is placed at the back of the bolt or rod to act
as a stop. I form the cheeks of two thicknesses of iron by bending the
iron back on itself or doubling it. I form rivets and shoulderings at
the ends opposite to where the iron is bent or doubled, and thus rivet to
the bolt plate. I form the loose staple in the same manner as the other
staples, and rivet it into a plate of double thickness for attachment to
the door post. The holes for the screws for fixing the bolt plate to the
door are made through the cross plates and on either side of the staples,
and the holes for the screws for fixing the loose staple to the door post
are made in the double plate and on each side of the loose staple. I
form the bolt or rod by putting together lengthwise two or more strips
of iron made to form when put together a hollow tube, either round, or
of other suitable shape in section, and fastening them to each other by
means of plates made to fit inside the tube thus formed, and having
rivets formed at suitable places in their peripheries, which are passed
through openings formed in the strips to receive them; the strips are
thus rivetted together. The end plates fitting inside the bolt or rod are
solid, and the intermediate plates have each a hole through them. I
form the knob in shape similar to those generally used, but having a
taper shank, which I pass through the bolt or rod and rivet over at the
back end. Previously to closing up the latter end of the bolt or rod I
pour in liquid plaster of Paris or other cement, which passes through the
openings in the intermediate plates and fills up the bolt or rod. The
shank of the knob is formed so that the plaster of Paris or other cement
will pass by cach side thereof. I form the barrel for a barrel bolt of one
or more strips of iron placed lengthwise and retained at each end by

page_text: cutting away a part of the inside pieces forming the staples and inserting
the ends of the barrel in the recesses thus formed.
-
The second part of my Invention refers to the construction of shuts,
bolts, tumblers, levers, rims, and inside and outside plates for door
latches and locks and like articles, and consists in laying upon each
other separate strips of iron cut to sizes to suit the shape of the required-
shut or bolt or other articles. The whole of the strips thus placed
together are heated and welded together or are rivetted together, thus
avoiding the necessity of being heated.
The third part of my Invention refers to the construction of hinges,
and consists in using iron of two or more pieces in thickness bent back
on itself and welded or rivetted together. The hole for the hinge pin is.
formed in the bend of the iron, and cither in the process of bending or
afterwards in the usual manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew Tildesley in the Great Seal Patent Office
on the 1st July 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MATTHEW
TILDESLEY, late of Tettenhall Wood, near Wolverhampton, in the
County of Stafford, and now of Willenhall, in the County of Stafford,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of January, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Matthew Tildesley, Her special licence that
I, the said Matthew Tildesley, my executors, administrators, and assigns,
or such others as I, the said Matthew Tildesley, my executors, admini-
strators, 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 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

page_text: CONSTRUCTION OF DOOR BOLTS AND OTHER FASTENINGS," upon the condition.
(amongst others) that I, the said Matthew Tildesley, 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 i
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 Matthew Tildesley, do hereby declare;
the nature of my said Invention, and in what manner the same is to 1
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) :-
The chief object of this Invention is to construct the articles named
in the title in such a manner that old (that is used) bale ties or hoops 1
or other narrow scrap iron may be used for the material composing the
said articles, and their cost be thereby considerably reduced. The
hollow bolt or rod herein-after mentioned may however be made from
either old or new iron at a less cost than forming it of solid iron as is
usual.

The first part of my Invention refers to the construction of door bolts,
and consists as follows:-I form the bolt plate by placing two strips of
iron edge to edge so as to form one plate of sufficient width. I place
other strips of iron, preferably three, but more or less if required, across
the two strips before mentioned, and in positions as required to suit the 2
staples. I form the staples of two thicknesses of iron, and form the ends
so as to leave an oblong rivet or rivets with the necessary shouldering.
I bend the staples to the required form and pass the rivets through
openings prepared for them through both the cross strips and plate
already mentioned. The staple rivets thus hold together the plate, cross 3
strips, and staples. I place one staple at the back of the bolt or rod to
act as a stop, as is now sometimes done, and prefer to lengthen the back
end of the bolt or rod so as to be partly retained by the said back staple
when the bolt is fastened, as is also now sometimes done with bolts to
give additional security. I form the cheeks of two thicknesses of iron 3.
by bending the iron back on itself or doubling it, and form rivets and
shoulderings at the opposite ends to where the iron is bent or doubled,

page_text: and thus rivet to the bolt plate. I form the loose staple in the same
manner as the other staples, and rivet it into a plate of double thickness
for attachment to the door post or other required part. The rivets
herein-before mentioned are similar to those ordinarily used, but are of
double thickness. I make the holes for the screws for fixing the bolt
plate to the door through the cross plates and bolt plate on each side of
the staples, and I make the holes for the screws for fixing the loose
staple to the door post or other required part in the double plate on each
side of the loose staple. I form the bolt or rod by putting together
lengthwise two or more strips of iron made to form when put together a
hollow tube, either round or of other suitable shape in section, and
fastening them to each other by means of plates made to fit inside the
tube thus formed, and having rivets formed at suitable places in their
peripheries, which I pass through openings formed in the strips (forming
the tube) to receive them; the strips forming the tube are thus rivetted
together. The end plates fitting inside the bolt or rod are solid, and
the intermediate plates have each a hole through them for a purpose
herein-after stated. I form the knob or handle in shape similar to those
generally used, but having a taper shank, which I pass through the bolt
or rod and rivet at the back end. Previously to closing up the latter
end of the bolt or rod I pour in liquid plaster of Paris or other cement,
which passes through the openings in the intermediate plates and fills
up the bolt or rod. The shank of the knob if fixed before the filling-in
material is inserted is formed so that the filling-in material will pass by.
each side thereof. I form the barrel for a barrel bolt of one or more
strips of iron placed lengthwise, and retained at each end by cutting.
away a part of the inside pieces forming two of the bolt staples, and
inserting the ends of the barrel in the recesses thus formed.
.
The second part of my Invention refers to the construction of shuts,
bolts, tumblers, levers, rims, and inside and outside plates for door
latches and locks and like articles, and consists as follows:-I lay upon
one another separate strips of thin iron cut to sizes to suit the shape of
the required shut or bolt or other article. I heat the whole of the strips
thus laid upon one another and weld them together or rivet them
together, thus avoiding the necessity of heating them; or I form parts
only of some of such articles (for instance, the tails of lock bolts) in the
manner described and weld or rivet such parts to other parts formed as

DESCRIPTION OF THE DRAWINGS.
My Invention as it refers to an ordinary door bolt and loose staple is
illustrated by Figures 1, 2, 3, 4, and 5, and as it refers to a barrel bolt
by Figures 6, 7, and 8. Where the same letters occur on any of the
views they indicate the same or corresponding parts.
Figure 1 shews a view of a bolt and loose staple as they are usually
seen when fixed in position; Figure 2 is a view of what would be the
under side when fixed, as in Figure 1; Figure 3 is an elevation of the
back end of bolt; Figure 4 is a similar elevation of the loose staple;
Figure 5 is an end elevation of one of the cheeks; Figure 6 is a
corresponding view to Figure 1; and Figure 7 is a corresponding view
to Figure 2, but the loose staple, which for a barrel bolt is the same as
for an ordinary bolt, is left out in both these views; Figure S is a
section through a, b, Figure 7.
A is the bolt plate, and is shewn to be formed of two plates each half
the width of the bolt plate; B, B, B, are strips of iron laid across the

page_text: manner.
two strips forming the bolt plate A in positions as shewn; C, C, C, are
the staples, and are shewn formed of two thicknesses of iron; c, c, c, c,
c, c, are rivets similar to those ordinarily used, but of double thickness
cut or pressed out with the staples, and form part thereof. The said
rivets c are shewn passed through the cross strips B and the bolt plate A,
and are rivetted over at the back of the bolt plate A in the usual
manner, thus firmly holding together the bolt plate A, the cross strips B,
and the staples C. The staple at the back end of the bolt is used as a
stop to the knob or handle, similarly as back staples are now used.
D, D, are the bolt cheeks, and d, d, the rivets, similar to those ordinarily
used, but of double thickness cut or pressed out therewith and forming
part thereof. The manner in which the iron is doubled over to form the
cheek is best seen in Figure 5. The rivets d, d, pass through the bolt
plate A only, and are rivetted over at the back thereof in the usual
E is the loose staple. The part to retain the rod or bolt end
is made in the same manner as the other staples, and is rivetted into a
plate e formed of two thicknesses of iron. F, F, F, F, F, F, are the
countersunk holes for the screws for fixing the bolt plate to the door.
For the sake of clearness they are shewn only in Figures 1 and 6.
G, G, are the countersunk holes for the screws for fixing the loose staple
to the door post. For the sake of clearness they are shewn only in
Figure 1. H is the bolt or rod; it is formed of two strips of iron each
bent to form a half hollow cylinder, and then placed together to form a
complete cylinder. The joint line is shewn along the centre of the
rod H in Figures 1 and 6. The two halves of the rod H are firmly held
together by circular plates 1, h, h¹, h', which fit inside the hollow
cylinder H, and are rivetted by means of rivets formed on them into
each half of the cylinder H, as best seen in Figures 3 and 8. The end
plates h, h, are formed solid, but the intermediate plates h¹, h', have an
opening formed through each of them, as shewn in Figure 8, to allow
the filling-in material to pass through them. K is the knob or handle;
it is similar to those ordinarily used, but the shank is made taper and
rivetted into the cylinder shell at the small end of the taper, as shewn.
The shank is shewn sufficiently small for the filling-in material to pass
by each side of it. All the rivetting in the bolt or rod H must be
countersunk flush or practically flush with the outside thereof, but the
remaining rivetting may be countersunk or not as desired. Previously
to closing up the latter of the two circular end plates h, h, liquid plaster
L

page_text: of Paris or other cement is poured into the rod H, which is thus filled
up solid. L, Figures 6, 7, and 8, is a barrel formed of two half hollow
cylinders similar to those for the rod. The halves are put together to
form a hollow cylinder, and are carried by two of the staples C, C, as
shewn. Some of the metal forming the inside layers of the staples C, C,
is dispensed with, as shewn at 1, 1, and the ends of the barrel are inserted
in the rebates thus formed. The barrel is described and shewn as
circular in section, but it may follow the exact shape of the inside layers
of the staples C, C, if desired. In the former case the rebate will not
require to be formed down to the bolt plate A unless for convenience of
manufacture

page_text: described or shewn, but claim all such modifications as follow obviously
rom and are in harmony with the description of this my Invention.
In witness whereof, I, the said Matthew Tildesley, have hereunto
set my hand and scal, this Seventeenth day of June, in the
year of our Lord One thousand eight hundred and seventy-
five.
