page_text: JOHN TYLER BARNSLEY BENNETT, 60 Anglesey St. Aston-juxta-Birmingham in
the County of Warwickshire Hinge Manufacturer, do hereby declare the nature
of my invention for "AN IMPROVED SECTION OF IRON OR STEEL BAR OR TUBE
APPLICABLE TO THE MANUFACTURE OF. HINGES AND TO OTHER PURPOSES" to be
as follows:-
My invention relates to "Improvements in the process of manufacturing welded
hinges" whereby a great saving in labour is effected.
In carrying out my invention, the iron or steel from which, I make my "impove-
ments in the process of manufacturing welded hinges" is first welded or drawn
from the skelp. (so called in the trade) in a similar manner that iron or steel tubing
is manufactured, but with this addition-I cause a flange to be added to the tube
running the whole lengeth-and to make this tube and flange together, I cause the
strips of iron or steel to be wider than the usual iron or steel strips from which the
usual iron or steel tubing is made from and these wide strips may also be made
with a grove or groves in them-Also in like manner some addition is made to
the skelp from which iron or steel tubing is drawn from-I cause it to be made
with a flange upon it so that when the tubing is drawn, there shall be a flange
upon it-Thus this iron or steel welded as above and in this shape with the hollow
tubing and the flange being in one peice-I form this iron or steel as being welded
into hinges the hollow tubing (divided into section cut out) answers the
purpose of the knuckles of the hinge, and the flange upon the hollow tubing
answers the purpose of the flaps of the hinge, when the tube and flange is divided
as required & cut apart Thus welded hinges are manufactured from this iron or
steel in a cold state, and out of its lengeths are cut single and double sides (so
called in the trade) of hinges, by milling, cutting, punching sawing, piercing, with
the most suitable tools machines, machinery, as may be required for the purpose of
making this iron or steel into hinges-When these two sides of hinges come
together single & double (and are jointed with a pin) they form the complete
hinge-In finishing the hinges, I shall adopt such dressing, squaring, plaining,
countersinking polishing, by machinery or otherwise as may be required or any
work upon them-It is understood, I shall make any modifaction for carrying out
my invention, and I do not limit myself to details, also any size, thickness,
engeth-shape, pattern of the welded iron or steel, I shall adopt for trade purposes.

I, JOHN TYLER BARNSLEY BENNETT of 60 Anglesey Street, Lozells, Birmingham,
in the county of Warwick. Hinge Manufacturer do hereby declare the nature of my
invention for AN IMPROVED SECTION OF IRON OR STEEL BAR, OR TUBE APPLICABLE
· TO THE MANUFACTURE OF HINGES, AND TO OTHER PURPOSES and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to the method of manufacturing iron or steel hinges, and
also to the section of iron or steel used in such manufacture, or similar sections of
iron or steel, as that such sections have not been hitherto made, but which may be
used to great advantage for several trade purposes; and has for its object the
forming out of flat strips of iron or steel either by rolling, drawing, (similar to tube
making) through dies, or by pressure between dies, such as stamping or such similar
tools in a suitable machine, a section of iron or steel which is readily manufactured
into hinges as hereinafter described and illustrated by drawings, and also has for
its object the use of this said section of iron or steel or any mere modification of
the same for other purposes of trade.
This section is in some respects similar to a tube but with the addition of a
flange formed upon it, such flange running along its entire length. The strips
from which this section is made, may be quite flat, or, if desired (to lessen the
manipulation in the after processes) may be prepared with a groove formed therein
out of which subsequently the tube part of the section shall be formed.
In adopting this section for the manufacture of hinges, the hollow tubing part
serves to form the knuckles of the hinge, with alternate portions of such tubing
part being cut away to allow of the corresponding half of the hinge to fit there-
into, while the flange part of the said section serves to form the flap of the hinge,
or that part through which the screw holes are pierced, by which it is secured in
working position. The cutting away or forming of these knuckles out of the tube
part of the section may be accomplished by milling, punching, sawing, or by other
similar suitable tools, or, they may be formed by piercing if desired, while in
an early stage of its formation, that is, before it is finally formed into the section
form already described.
By the cutting away of these parts thus forming the knuckles, I form the single
or double, or interchangeable sides of the hinge, which are then jointed by means
of a central pin, thus constituting the complete hinge. In finishing the hinge
I shall adopt such, dressing, squaring, planing, countersinking, or polishing &c as
may be necessary to complete them. This section of iron or steel formed after the
manner herein-stated for hinges, or any mere modification of the same is new, and
is applicable to other constructive uses.
In carrying out this my said invention I take the strip as shewn in section at
Fig. 1, or as shewn in Fig. 1A upon the drawings, and roll, or draw, or stamp it
into the form or section Fig. 2; then again from the form or section Fig. 2 it is
further formed by rolling, drawing or stamping into section form Fig. 3, where it is

page_text: ready for welding; or in some instances it may be welded at the same time as
it is thus formed, but more generally first formed thus, ready for welding, and
afterwards welded into section shewn at Fig. 4 by a similar separate operation.
This section of iron or steel, together with similar sections shewn in process of
formation at Fig. 9, 10, & 11 may be as aforesaid used for other purposes of
construction, and may for such purposes be produced not welded, as shewn at
Fig. 3 & 10, or, they may be welded as shewn at Fig. 4 & 11.
In forming hinges out of the section shewn at Fig. 4, I should cut away portions
of the tube part a, as shewn in Fig. 5, in order to form the knuckles of the hinge.
These knuckles would vary in number and order according to the size of the hinge to
be formed, as there may be single and double sides, that is, an extra knuckle on one
side to what there is upon the other, or these sides may be made interchangeable,
that is an equal number of knuckles upon each side, or in forming these knuckles,
I may pierce the hole necessary for their formation, through the strip in its earlier
stages of manipulation, as for instance I may pierce it as shewn at b, Fig. 7.
Having formed the knuckles, it is dressed and finished as shewn at Fig. 8,
varying in size and shape of course, to suit requirement.
Fig. 12 shews tools which may be adopted in suitable machine for welding the
sections at Figs. 3 & 10 into sections Fig. 4 & 11 by stamping or other pressure.
These tools may also if desired, be used to form sections shewn in Figs. 2 & 9,
but when used in the carrying out of this my invention, they would be more
practically adapted for the welding process, than the earlier stages.
Fig. 13, shews a pair of rolls that may be used to form and weld the sections at
Figs. 2, 3, 4, 9, 10 & 11, although the shape and position of the grooves c & d may
be varied to suit requirements.
Fig. 14 shews one form of die through which the tube with flange may be drawn
through its successive stages.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The sections of iron or steel, as hereindescribed and shown upon the drawings at
Figs. 3, 4, 10, & 11, or any mere modification of them, for the manufacture of
hinges or other constructive purposes.
