I FREDRICK WILLIAM BRAMPTON of No 14 Oliver Street. Birmingham in the
County of Warwick, Manufacturer, do hereby declare the nature of my said
invention for "IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF FENCING
WIRE STAIR AND BEDSTEAD RODS AND OTHER ARTICLES REQUIRING SIMILAR TREAT-
MENT and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement that is to say :-
My Invention has for its object improvements in Machinery for the manufacture
of fencing wire and other articles requiring similar treatinent which enables me to
effectively produce a spiral rod either solid or if necessary hollow, in the most
expeditious and certain manner with a minimum amount of power and in a most
simple and inexpensive way.
In order that my invention may be clearly understood and easily applied in
practice, I have appended. hereunto two examples of the Application of my
invention and from these and the following explanations it will be quite easy
to extend the applications to other varying conditions and circumstances which
are met with in practice.
Figure 1. is a side elevation of a machine suitable for making fencing wire.
Figure 2 is an end elevation of the same machine.
Figure 3 is a plan of the same machine and
Figure 4 shows one of the variations in detail which may be accomplished
without departing from the principle of the invention.
The machine shown by Figures 1, 2 and 3 consists of a pair of rolls A and B.
which are geared to run together by the pinions C and D and are firmly set in the
framing E which is fitted with proper glands journals and other parts for running
such rolls truly and for their adjustment. These rolls are driven by the handle F
or other suitable motion though the shaft H which carries the pinion J working
into the wheel K which is keyed upon the end of the journal of the lower roll B.
The spindle H also drives a longitudinal shaft M through the mitre or bevelled
wheels L and N while the other end of this shaft M carries the disc P which is
fitted with the dovetail slot p¹ in which an adjustable block is fixed at any desired
position for giving an eccentric motion to the die plate which works upon the fast
D .

page_text: pin R by means of the sliding block q¹ which turns upon the pin R allowing the
plate to slide up and down so as to give the die end q2 the circular motion
indicated by the dotted circle 93. The action of the machine is as follows.
The wire S is fed between the rolls A B and they carry it into the die plate Q
which carries a little steel die shown by dotted lines.and in section at Figure 5
which can be exchanged or renewed at any time Now the circular movement
described by,this die plate Q produces upon the wire rod a perfect spiral or twist
as though it had been wound around a core or mandril and this twist may be
regulated partly by the distance of the die from the rolls or the hole T in the
frame as well as by the speed of the shaft M in its relation to the speed of the
peripheries of the rolls A and B The distance of the die plate Q from the hole T
or rolls A and B may be made adjustable so as to be easily set to any distance and
by changing the wheels K and J any desired pitch of spiral may be produced upon
the wire or other article passed through.
Or the rolls may be placed as shown by Figure 4 the wire being fed in as shown
by the arrow and immediately it leaves the rolls it would. pass through the die
plate U and hollow spindle V issuing at the other end as shown in a spiral state
The die plate U is adjustable and this would be found a simple and effective
modification because the hollow spindle V would tend to keep the wire steady
until it was wound upon the reel.
In other cases the wire may be drawn through a die by a drum with an eccentric
die plate between the drum and the disc similar to Q which would also produce the
spiral very simply and without departure from the principle of my invention.
Such machines would twist stair rods or the rods used in the manufacture of
parts of bedsteads and hollow tubes and other articles requiring to be so treated.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The improvements in machinery for the manufacture of fencing wire and other
articles of a die plate made to travel with the wire or other article around the
axis or direction in which the wire or other article is then moving substantially
as herein set forth.
