Improvements in the Manufacture of NOTTOK Latenes.
We CHARLES STEER of West Heath House Northfield in the County of Worcester
Director of Nettlefolds Limited and JOSEPH HENRY STUBBS of No. 8 St. Marks Street
Birmingham in the County of Warwick Tool Maker do hereby declare the nature of
this Invention to be as follows :-
Our invention consisis in making Norfolk latches from strong wire or wire rods
preferably of iron or steel substantially in the manner hereinafter described.
In making a Norfolk latch according to our invention we take a length of cylindrical
wire or a cylindrical wire rod and flatten a portion of it near one end the other parts of
the wire or rod being left of the original figure. The extreme end of the wire near the
flattened portion is bent into a circular eye and constitutes the joint end of the latch the
said joint end being connected to the door by a screw pin passed through the said eye and
driven into the door. From the flattened part of the wire that half of the body of the
latch most distant from the joint end is formed. This is effected by doubling the said
flattened part near its middle and bringing the doubled parts parallel to one another.
The unbent and cylindrical part of the wire forming a prolongation of the lower part
of the doubled flattened portion or body of the latch is next so hent and doubled upon
itself as to form at right angles to and crossing the body of the latch the back and
front handles and lifters of the latch. About one half of each of the handles is bent
into a loop and the looped parts are bent downwards at right angles to the other part.
A Norfolk latch is thus made from a single piece of wire or wire rod.
The back part of the lifter of the latch passes through the door and the flattened
portion of the body of the latch works in the "keep" or loop fixed on the door the
curved end of the flattened portion of the body engaging in the catch on the door
frame in the ordinary way.
The flattening of the fore part of the latch may be effected after the wire has been
bent as described instead of previously.

Improvements in the Manufacture of Norfolk Latches.
We CHARLES STEER of West Heath House, Northfield, in the County of Worcester
Director of Nettlefolds Limited and JOSEPH HENRY STUBBS of No. S St. Mark's
Street Birmingham in the County of Warwick, Tool Maker, do hereby declare the
nature of our Invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:
Our invention consists in making Norfolk latches from strong wire or wire rods
preferably of iron or steel substantially in the manner hereinafter described.
In making a Norfolk latch according to our invention we take a length of cylindrical
wire or a cylindrical wire rod and flatten a portion of it near one end the other parts
of the wire or rod being left of the original figure. The extreme end of the wire near
the flattened portion is bent into a circular eye and constitutes the joint end of the
latch the said joint end being connected to the door by a screw pin passed through
the said eye and driven into the door, or by a rivet passed through the eye and riveted
on a plate which is screwed on the door. From the flattened part of the wire that
half of the body of the latch most distant from the joint end is formed. This is
effected by doubling the said flattened part near its middle and bringing the doubled
parts parallel to one another. The unbent and cylindrical part of the wire forming a
prolongation of the lower part of the doubled flattened portion or body of the latch, is
next so bent and doubled upon itself as to form at right angles to and crossing the
body of the latch the back and front handles and lifters of the latch. About one half
of each of the handles is bent into a loop and the looped parts are bent downwards at
right angles to the other part. A Norfolk latch is thus made from a single piece of
wire or wire rod.

The back part of the lifter of the latch passes through the door and the flattened
portion of the body of the latch works in the "keep" or loop fixed on the door the
curved end of the flattened portion of the body engaging in the catch on the door
frame in the ordinary way.
The flattening of the fore part of the latch may be effected after the wire has been
bent as described instead of previously.
We will now describe with reference to the accompanying Drawings the manner in
which our invention is to be performed.
Figure 1 represents in side elevation and Figure 2 in plan a Norfolk latch applied
to a door, the said latch being made according to our invention from a length or piece
of cylindrical wire or wire rod.
a, b is the body of the latch the half being flattened and doubled, the said flattened
half of the body working in the keep or loop c fixed on the door the curved end of
the flattened fore part of the latch body engaging in the catch d on the door frame as
usual. At the end of the half a of the latch body is the eye e which turns upon the
screw pin driven into the door or riveted on a plate: 9 g are the lifters which are

page_text: passed through an opening in the door. The said lifters are situated at right angles
to the latch body a, b and have at their ends the back and front handles h, h which are
partly looped.
In making the said Norfolk Latch we proceed as follows:-We take preferably a
length of cylindrical wire or wire rod and make on one end of it a loop or eye e to
form the joint end of the finished latch body as represented in Figure 3. A portion of
the wire at the joint end e is next bent nearly parallel to the unbent portion of the
wire so as to form a doubled portion as represented in Figure 4. That half of the
doubled and parallel parts nearest the curved end is next flattened at b as represented
in front elevation and edge view in Figure 5. The body of the latch is thereby formed.
The unbent and cylindrical part of the wire Figure 5 forming a prolongation of the
lower part of the doubled and flattened portion of the latch body is next bent at
right angles to the said body as illustrated in Figure 6. The wire is next bent into
the loop at one side of the body of the latch as represented in Figure 7 and the
remaining unbent portion of the wire i is bent into a loop at the other side of the
body of the latch as represented in Figure 8. The last bent portions k, I cross
the body of the latch and constitute the partly made lifters and front and back handles
of the latch. Portions of the looped parts k, are next closed upon one another
leaving loops at each end of the handle parts of the nearly finished latch as represented
in the side elevations, taken at right angles to one another, Figures 9 and 10 and in
the plan Figure 11. About one half of each of the handle parts k, lis finally bent
downwards at right angles to the other part as represented in the finished latch shown
in side elevations in Figures 12 and 13 and plan in Figure 14. A Norfolk latch is in
this way made from a single piece of wire or wire rod. The parts of the finished
Norfolk latch represented in Figures 12. 13 and 14 are marked with the same letters
of reference as corresponding parts of the latch represented applied to a door in
Figures 1 and 2.
Having now particularly described and ascertained the nature of our invention
and the manner in which the same is to be performed we declare that we claim as
our invention
Manufacturing Norfolk Latches each from a single piece of strong wire or wire rod
preferably of iron or steel by the process or combination of processes substantially as
herein before described and illustrated in the accompanying Drawings.
