IMPROVEMENTS IN THE MANUFACTURE OF HINGES
Year: 1870

page_text: LETTERS PATENT to Henry Timmins, of Acton, in the County of
Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF HINGES."
Sealed the 15th November 1870, and dated the 3rd June 1870.
PROVISIONAL SPECIFICATION left by the said Henry Timmins at
the Office of the Commissioners of Patents, with his Petition, on
the 3rd June 1870.
I, HENRY TIMMINS, of Acton, in the County of Middlesex, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF HINGES," to be as follows :-
—
In manufacturing hinges according to my Invention I form by the
drawing process strips or bars of metal having in cross section the
figure of one of the flaps of a hinge, excepting that the knuckle part
from which the joint is to be formed has no perforation, that is to say,
is without the hole in which the pin forming the joint is inserted. The

page_text: said strips or bars of metal are cut into suitable lengths, and portions of
the knuckle part are cut away at the required intervals. A hole is
drilled in the axis of the knuckle for the joint pin, and the two flaps
are put together and connected by the joint pin in the usual manner.
The screw holes for attaching the flaps of the hinge to the door
or other article are formed either by stamping, piercing, or drilling.
Instead of forming the said strips or bars by the process called
drawing they may be formed by rolling, but I prefer the drawing
process.
My Invention is especially applicable to the manufacture of hinges.
made of brass, but may also be applied to the manufacture of hinges of
other alloys or metals.
Hinges are manufactured according to my Invention more economically
than by the ordinary methods, and are very strong and durable and neat
in appearance.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Timmins in the Great Seal Patent Office
on the 21st November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
TIMMINS, of Acton, in the County of Middlesex, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of June, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-third year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Henry Timmins, Her special licence that I, the said
Henry Timmins, my executors, administrators, and assigns, or such
others as I, the said Henry Timmins, 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 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
HINGES," upon the condition (amongst others) that I, the said Henry

page_text: Timmins, 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 Henry Timmins, 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 thereof, that is to say :-
In manufacturing hinges according to my Invention I form by the
drawing process strips or bars of metal having in cross section the
figure of one of the flaps of a hinge, excepting that the knuckle part
from which the joint is to be formed has no perforation, that is to say,
is without the hole in which the pin forming the joint is inserted. The
said strips or bars of metal are cut into suitable lengths, and portions of
the knuckle part are cut away at the required intervals. A. hole is
drilled in the axis of the knuckle for the joint pin, and the two flaps are
put together and connected by the joint pin in the usual manner. The
screw holes for attaching the flaps of the hinge to the door or other
article are formed either by stamping, piercing, or drilling. Instead of
forming the said strips or bars by the process called drawing they may
be formed by rolling, but I prefer the drawing process.
My Invention is especially applicable to the manufacture of hinges
made of brass, but may also be applied to the manufacture of hinges of
other alloys or metals.
Hinges are manufactured according to my Invention more economically
than by the ordinary methods, and are very strong and durable and neat
in appearance.
Having explained the nature of my Invention I will proceed to
describe with reference to the accompanying Drawing the manner in
which the same is to be performed.
Figure 1 represents in side elevation, and Figure 2 in end elevation a
strip or bar of brass or other metal or alloy from which hinges are to be
made according to my Invention.
The said strip or bar is marked a, b, and has in cross section the

page_text: figure of one of the flaps of a hinge, excepting that the knuckle part b
of the strip or bar is solid.
In making hinges from the said strip or bar a, b, it is cut into suitable
lengths, and portions of the knuckle part 6 of the said lengths are cut
away at the required intervals, as represented in Figures 3 and 4,
where c represents one flap of the hinge and d the other flap of the
hinge. In the flap c portions of the knuckle part 6 are cut away,
leaving three knuckles or eye pieces e, e, e, and portions of the knuckle
part of the other flap d are cut away, leaving two knuckles or eye
pieces f f f the several knuckles being so arranged that they are
capable of being fitted together. Each of the said knuckles e, f, is next
drilled with a hole for the joint pin. The hollow knuckles e, f, of the
two flaps c, d, of the hinge are then fitted together in the manner
represented in plan in Figure 5, horizontal section in Figure 6, cross
section in Figure 7, and end elevation, with the flaps closed, in Figure 8. 1
The said flaps are then ready to receive the joint pin 9, represented
separately in Figure 9.
Figure 10 represents in plan, Figure 11 in horizontal section, Figure 12
in cross section, and Figure 13 in end elevation with the flaps, folded
hinges, the flaps of which are jointed together by the joint pin g being 2
passed through the hollow knuckles of the said flaps and rivetted in the
usual manner. The hinges are finally finished by forming the screw
holes in the flaps as illustrated in Figures 10, 11, and 12. The knuckle
part 6 of the strip or bar a, b, Figures 1 and 2, through which the joint
pin passes may be drawn hollow, in order to save the drilling process
herein-before described.
Having now described the nature of my Invention and the manner
in which the same is to be performed, I wish it to be understood that I
do not limit myself to the precise details herein described and illustrated,
as the same may be varied without departing from the nature of my
Invention; but I claim as my Invention, the improvements in the
manufacture of hinges, herein-before described and illustrated in the
accompanying Drawing, that is to say, making hinges from drawn or
rolled strips or bars of metal, having in cross section the figure of one of
the flaps of a hinge, the knuckle part of the said strips or bars being
either solid or tubular, the said strips or bars being cut into lengths, and
portions of the knuckle part of the said lengths being cut away at
intervals to form the knuckles, and when necessary drilling the hole in

page_text: the said Knuckles for the joint pin, substantially as described and
illustrated.
In witness whereof, I, the said Henry Timmins, have hereunto set
my hand and seal, this Nineteenth day of November, in the year
of our Lord One thousand eight hundred and seventy.
