page_text: LETTERS PATENT to Stephen Tuddenham, of Lower Marsh, Lambeth,
in the County of Surrey, Engineer, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF METAL GATES, APPLICABLE ALSO TO TIE ROD
COUPLINGS, HINGES FOR SHOP BLIND ARMS, AND OTHER USEFUL PURPOSES."
Sealed the 24th Jannary 1871, and dated the 1st November 1870.
PROVISIONAL SPECIFICATION left by the said Stephen Tuddenham
at the Office of the Commissioners of Patents, with his Petition,
on the 1st November 1870.
I, STEPHEN TUDDENHAM, of Lower Marsh, Lambeth, in the County
of Surrey, Engineer, do hereby declare the nature of my said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF METAL GATES, APPLICABLE ALSO O
TIE ROD COUPLINGS, HINGES FOR SHOP BLIND ARMS, AND OTHER USEFUL PURPOSES,"
to be as follows:-
This Invention relates to metal gates, and consists in attaching
1 malleable cast metal socket pieces having lugs cast thereon to the back
and front stiles of the gate, the transverse bars which connect the back

page_text: and front stiles being secured thereto by tangs which pass. thro' the
socket pieces and also thro' the stile, and are rivetted thereto, other
rivets passing through the lugs on the socket pieces and through the
transverse bars, being employed for further security. The socket pieces
for the front stiles may be trough shaped so as to clip or surround the
three sides only of the stile, and may be further secured thereto by
screws, and may have a single lug only cast cast thereon in lieu of double
lugs as in the case of the socket pieces for the back stiles, between
which double lugs the end of the transverse bar enters. In some cases
the socket pieces for the front stiles may have side plates cast thereon
for the reception of the lock or other fastening of the gate. The same
system of preparing malleable cast metal socket pieces having lugs cast
thereon is equally applicable to the junction pieces for the tie rods of roofs
and other structures wherein tie rods are employed, the said combined
sockets and lugs being secured in their place either by twisting the bar
on which the socket is placed or by keying or otherwise. The lugs are
cast on at various angles according to requirement, and are provided
with bolt or pin holes for connecting the end of the tie rod thereto. It
is also proposed to form joints or hinges for shop blind arms and other
purposes in the same way by casting them in the form of a socket piece
and subsequently annealing them, the socket piece being fitted on to the
arm in any convenient manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Stephen Tuddenham in the Great Seal Patent
Office on the 1st May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
TUDDENHAM, of Lower Marsh, Lambeth, in the County of Surrey,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of November, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Stephen Tuddenham, Her special
license that I, the said Stephen Tuddenham, my executors, adminis-
trators, and assigns, or such others as I, the said Stephen Tuddenham,

page_text: my executors, administrators, or 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 CONSTRUCTION OF METAL GATES, APPLICABLE ALSO TO TIE ROD COUPLINGS,
HINGES FOR SHOP BLIND ARMS, AND OTHER USEFUL PURPOSES," upon the condition
(amongst others) that I, the said Stephen Tuddenham, my executors or
administrators, by an instrument in writing under my hand and scal
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Stephen Tuddenham, do hereby
declare the nature of my 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, and the letters and figures marked thereon (that is to
say):
My said Invention relates chiefly to metal gates, and is also applicable
to tie rod couplings, hinges for shop blind arms, and other useful purposes.
of a like nature. It consists as applied to metal gates in attaching in
any convenient manner malleable cast metal socket pieces having lugs.
cast thereon to the back and front stiles of the gate, the transverse bars.
which connect the back and front stiles being secured thereto by tangs.
which pass through the socket pieces and also through the stile and are-
rivetted thereto, other rivets passing through the lugs on the socket
pieces and through the transvers bars, being employed for further
security. The socket pieces for the front stiles may be trough shaped
so as to clip or surround the three sides only of the stile, and may be.
further secured thereto by screws, and may have a single lug only cast
thereon in lieu of double lugs as in the case of the socket pieces for the
back stiles, between which double lugs the end of the transverse bar
enters. In some cases the socket pieces for the front stiles may have-
side plates cast thereon for the reception of the lock or other fastening.
of the gate. The same system of preparing malleable cast metal socket
pieces having lugs cast thereon is obviously equally applicable to the
junction pieces for the tie rods of roofs and other structures wherein tie

page_text: rods are employed, the said combined sockets being secured in their
places either by twisting therein the tie rod or bar on which the socket
is placed when such rod or bar passes entirely through the socket, or by
keying or otherwise.
The lugs are cast on the sockets at various angles
according to requirement, and are provided with bolt or pin holes for
connecting the end of the tie rod thereto. I also propose to form joints or
hinges for shop blind arms, and for other like purposes, in the same way
by casting them in the form of a socket piece, and subsequently
annealing them, the socket piece being fitted on to the arm in any
convenient manner.
And in order that my said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the several Figures on the annexed Sheet of Drawings,
the same letters of reference indicating corresponding parts in all the
corresponding Figures..
Figures 1 to 5 inclusive illustrate my improvements in metal gates;
A, A, are the malleable cast metal socket pieces having lugs or
brackets B, B, cast thereon, which are attached to the back and front
stiles C, C¹, of a metal gate, the transverse bars D which connect the
back and front stiles being secured thereto by tangs a, a, which pass
through the socket pieces A and also through the stile C or C¹, and are
rivetted thereto as shewn in Figures 1, 2, 3, and 4, other rivets b, which
pass through the lugs or brackets on the socket pieces A and through
the transverse bars, being employed as shewn in Figure 6 for further
security. The socket pieces A for the front stiles shewn in Figures 3
and 4 may be trough shaped, so as to clip or surround the three sides
only of the stile C', and may be further secured thereto by screws c, and
may have a single lug or bracket B only cast thereon (see Figure 3) in
lieu of double lugs as shewn in Figure 1, which represents a socket
piece for the back stile. Between these double lugs or brackets B, B,
the end of the transverse bar D enters. In some cases the socket pieces
for the front stiles may have side plates E cast thereon for the reception
of the lock or other fastening of the gate, as shewn in Figure 5, but in
every case the socket A and its bracket or brackets B or lock plate E
(as the case may be) are cast in one piece and subsequently annealed.
By this mode of construction a considerable economy of labour in
manufacturing or constructing the parts is effected, as all forging is
entirely obviated.

page_text: Figures 6 and 7 represent the application of my malleable iron socket
pieces and brackets to the tie rods of roofs for the purpose of coupling
or connecting the same; A is the socket piece, and B, B, the brackets or
lugs cast thereon (shewn clearly in the section Figure 6) with pin holes
drilled therein to receive the coupling or joint pin a. These brackets
or lugs are cast at different angles, as shewn, to the socket to suit the
particular angle of the tie rods C, C, to which rods the socket pieces
may be secured by either twisting the rods therein as shewn, or by keys,
or pins, or otherwise as found most convenient.
Figures 8 and 9 represent the hinges of shop blind arms formed in
malleable iron socket pieces A. secured to the arms B.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used
or carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the manu-
facture of malleable cast-iron socket pieces having brackets, lugs, plates,
or hinge jaws cast thereon, and the application of the same to the front
and back stiles of metal gates, also to tie rod couplings, shop blind arms,
and other useful purposes substantially as herein-before described and
illustrated by my Drawings.
In witness whereof, I, the said Stephen Tuddenham, have to this
my Specification set my hand and seal, this Twenty-ninth day of
April One thousand eight hundred and seventy-one.
STEPHEN TUDDENHAM. (L.S.)
