Improved Mechanism or Machine for Beading and Wiring the Edges
of Strip Metal and such like.
I, FREDERICK HENRY WILLIAM BREININGER, Engineer to White & Pike
Limited, of Longbridge Works, Northfield, in the County of Worcester, Cycle
Accessories Manufacturers, do hereby declare the nature of this invention to
be as follows:-
The mechanism or machine according to this invention is for beading, or
beading and wiring, the longitudinal edges of strip metal and similar substances,
and is especially applicable for use in the manufacture of mud guards, and it
is characterised by the following essential parts: A flat plate of approxi-
mately five or six inches in length and of the breadth of the strip metal to be
beaded has both its longitudinal edges turned over upon itself, so as to stand
some distance away from the adjacent surface of the plate and form grooves
upon each of the said longitudinal edges. This plate is practically a draw-
plate through which the strip metal is passed to have its edges shaped or turned
up into beadings, the said plate being of a taper figure longitudinally, and the
said shaping or beading taking place within the grooves as aforesaid, that is to
say, the breadth of the starting or feed side of the draw plate is a little larger
than the flat metal unbeaded strip, and the finished side of the said plate of the
exact breadth of the strip when the beaded edges are formed; the grooves
abounding the longitudinal edges of the said plate following the taper so as
to act upon the edges of the strip gradually, step by step, and roll them over or
coil thein up into a circular-sectioned bead.
The draw plate, as aforesaid, has connected to it, either as a fixture or remov-
ably, a centrally-disposed thin bar length, preferably in the form of a plate,
which forms a mandrel to the strip in the formation of the beaded edges, as the
said strip is drawn through the draw-plate between this bar and the beaded edges
are rolled up within the grooves of the draw-plate between the hollowed-out
edges of the said bar; the disposition of the said bar being such as to leave a
space in the draw plate, for the drawing through of the strip, equal to the section
of the strip when finished and following it in the gradual shaping of its beadings.
The strip to be shaped is pulled through the draw plate and mandrel by rolls
which are disposed either in front of the said draw plate, or at the rear, or both,
so as to nip the metal frictionally and feed it along.
If the beaded edges of the metal strip are required to have wires enclosed,
it will be only necessary to feed the wires along with the strip into the draw-
plate, and affix to the front of the said draw-plate guides for the wires, the said
guides being preferably adjustable.
Instead of forming the beaded edges by the draw plate, as described, small
grooved rolls may be disposed on both sides of the strip near the feed rolls so
as to act gradually upon the edges of the strip as it is gripped by the feed rolls,
and roll it over in the groove, in which case a mandrel may or may not be
needed.

page_text: The mandrel may be made in two or more parts and, in the case of the draw
plate, be fitted to the said plate adjustably; and the grooves of the said draw
plate may be formed by attached strips, which would allow of varying-sized
beads being turned up by a small change in the mechanism.
Improved Mechanism or Machine for Beading and Wiring the Edges
of Strip Metal and such like.
I, FREDERICK HENRY WILLIAM BREININGER, Engineer to White & Pike.
Limited, of Longbridge Works, Northfield, in the County of Worcester, Cycle
Accessories Manufacturers, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement : -
The mechanism or machine according to this invention is for beading and
beading and wiring the longitudinal edges of strip metal and other substances,
and is particularly applicable for use in the manufacture of mud guards of
cycles. It is characterised by the following parts: A flat plate, of approxi-
mately five or six inches in length and of the breadth or width of the strip metal
or other substance to be beaded, has both its longitudinal edges turned over
upon itself so as to stund some distance away from the adjacent surface of the
plate and form grooves upon each of the said edges. This plate is practically
a draw-plate, through which the strip metal is forced to have its edges shaped
or turned up into beadings; the said plate being of a taper figure longitudinally,
and the said shaping or beading taking place within the taper grooves. In other
words, the breadth of the starting or feed side of the draw-plate is a little larger
than the flut unbeaded metal strip, and the finishing side of the said plate is
of the exact breath and shape of the strip when the beaded edges are formed;
the grooves abounding the longitudinal edges of the said draw-plate following
the taper so as to act upon the edges of the strip gradually, step by step, and
roll them over or coil them up iuto circular-sectioned beads. The draw-plate,
as aforesaid, has connected to it, either as a fixture or removably, a centrally
lisposed thin bar-length, preferably also in the form of a plate, which consti-
tutes a mandrel to the strip in the formation of the beaded edges, as the said strip
is drawn through the draw-plate between the said draw-plate and this bar, and
the beaded edges are rolled up within the grooves of the draw-plate between the
said grooves and the hollowed-out longitudinal edges of the said bar; the dis-
position of the said bar being such as to leave a space in the draw-plate equal
to the section of the strip when finished and following it in the gradual shaping
of its beadinga. The strip to be shaped is pulled through the draw-plate and
mandrel by rolls which are disposed either in front of the said draw-plate or at
the rear, or both, so as to nip the metal frictionally and feed it along.
If the beaded edges of the said metal strip are required to have wires enclosed,
it will be only necessary to feed the wires along with the strip into the draw-
plate and affix to the front of the said draw-plate guides for the wires, the said
guides being preferably adjustable.
Instead of forming the beaded edges by the draw-plate as described, small
grooved rolls may be disposed on both sides of the strip near the feed roll, so 6

page_text: as to act gradually upon the edges of the strip as it is gripped by the feed rolls,
and roll it over in the groove, in which case a mandrel may or may not be
needed.
The mandrel may be made in two parts and in the case of the draw-plate, be
fitted to the said plate adjustably, and the grooves of the said draw-plate may
be formed by attached strips, which would allow of varying sized beads being
turned up by a small change in the mechanism.
The invention as aforesaid is shown carried into practical effect in the accom-
panying sheet of drawings; Fig. 1 showing a side section; Fig. 2 a front eleva-
tion, partly in section; Fig. 3 a topside plan; and Figs. 4 and 5 detail views.
Fig. 6 is a modification of this invention. In these drawings the draw-plate a
is built up of two parts a², as, horizontally supported within holsters or
uprights, a, a, mounted upon a suitable bed a. The said parts are fitted to
slide within machined cut-away parts c, c, of the uprights so as to approach or
recede from each other through the operation of traversing screw bolts e³, c
which effects an adjustment of the said parts to accommodate varying sized
strips to be beaded. A taper groove d of a bead section is formed in the inner
edge of each of the parts a³, a³, the said grooves being of a cross-sectional
shape to suit the beading required, and the taper commencing from the front
or feed side a of the draw-plate as the largest part, and narrowing in to the
rear and finishing side, a, in the manner shown clearly by Figs. 3 and 4.
The mandrel e is a flat metal plate lying between the grooved edges of the
parts a, a, so that its longitudinal edges e, e, enter the grooves d, d, for a
short distance, the said edges conforming to the taper of the grooves and running
the entire length thereof. This mandrel is fixed in this position but is capable
of adjustment, and its function is to help in the coiling up of the edges of the
strip to be beaded, and to prevent the said strip buckling during the shaping.
The dispositions of the draw-plate and the mandrel with respect to each other,
and with a metal strip shown in position between them, is clearly seen from
Figs. 4 and 5.
In the drawings the mandrel e is fixed in position by a clamping action upon
the draw-plate, and through a strap f and a screw bolt and nut f, f. Behind
the draw-plate and mandrel is arranged a pair of rolls 9, 9, journalled in the
holsters or uprights a, a. These rolls frictionally grip onto the metal strip, k,
under operation of beading and pull it through the space between the said draw-
plate and mandrel. The said strip may however be forced into the machine
as well as pulled through by the provision of a pair of rolls g³, 9³, (shown in
dotted lines in Fig. 1) in front of the shaping devices a and e.
A guide, i, for feeding the strip forward to the machine is provided upon
the front of the machine's frame, and this is made adjustable so as to ensure a
correct feed of the strip into the shaping devices.
From Fig. 4 it will be clear that the unbeaded strip to be shaped enters at the
feed side a of the draw-plate and mandrel, and that its edges are gradually
operated upon in the grooves d, d, as it is drawn or forced through between the
said draw-plate and mandrel by the rolls, so that when it issues from the finished
side a³, its edges are shaped or coiled up to the beaded section required.
In Fig. 4 is shown by dotted lines n, how a wire can be inserted in the bead-
ings at the same time as the beadings are formed.
In the modification, Fig. 6, the feed rolls 9, 9, are arranged central with a
pair of small grooved rolls m, m, which latter roll up the edges of the strip in
the manner shown. These rolls m, m, take the place of the draw-plate in the
first described form, and with them a mandrel may be used if necessary.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
-
First. In beading the edges of strip metal and other substances, the use of

page_text: a draw-plate having within it taper grooves wherein the edges of the strip are
gradually shaped by being drawn through, substantially as described.
Second. A mechanism for beading the edges of motal and other strip, com-
prising a draw-plate having taper grooves within it, a taper mandrel whose longi-
tudinal edges extend into said grooves, and means for feeding forward the strip
to be shaped, substantially as described.
Third. The combination of a draw-plate built up of parts a, a³, having taporing
grooves within them, a mandrel e disposed central to said draw-plate and con-
forming to its taper and whose longitudinal edges project into said grooves,
feed rolls g, g, for feeding said strip, and devices for adjusting said draw-plate,
substantially as described.
Fourth. A mechanism for beading the edges of strip metal and such like con-
structed, arranged and working in the manner specifically as set forth.
