I, BENJAMIN EDWARD HALFORD of 15 Monument Road Birmingham in the
County of Warwick, Machinist do hereby declare the nature of my invention for
IMPROVEMENTS IN BRACELETS AND BANGLE BRACELETS AND IN THE METHOD OF
MANUFACTURING THE SAME to be as follows:-
For impressing upon bracelets and bangle bracelets any ornamental pattern or
figure in the same process, that it is drawn and wound, that is, of drawing the
metal into required shape then bending or winding to the size required to go
round the arm, and impressing any kind of ornamental pattern or figuring on the
metal all at one process, which can be done either in an ordinary screw cutting
lathe, or in a machine specially made and adapted for it, my invention is to be
applied to any kind of flat rolled metal, such as gold, silver german-silver, copper,
brass and all other similar kinds, used in Jewellery, in using the metal for my
process and invention it is cut into strips the required width then being drawn
through what is known as a draw plate, which is a piece of steel having a hole
piercing it the shape the metal is required, the most common shape being half
round or belcher with the edges of the metal turned into a wire or small tubes, this
said draw plate is fixed in a frame or holder which is fixed in the tool rest of the
saddle of the lathe, after passing through this plate the metal is then wound round
a spit or mandril fixed between the centres of the lathe, which mandril is screw cut
with two grooves so as to allow the two wires or small tubes edges, on each edge
of the metal to fall into these spaces or grooves so cut away, as the metal is being
wound on to the mandril, whilst the centre part between the two grooves cut in
the mandril, and which will be of different widths according to the width of the
bracelet or bangle, stands up the top side being rounded sufficient to keep the
half round part of the metal full up to the required shape. Now I purpose with
my invention putting or impressing any ornamental pattern on the centre half
round part of the bracelet or bangle bracelet by impressing the same pattern upon
the raised part of the mandril, or that part between the two grooves by means of
what are called milling tools or small rollers agreeing in shape with the raised part
of the mandril and having the pattern cut or engraved or embossed upon them so

page_text: that when the metal is drawn through the plate and wound upon the mandril this
said milling tool or roller with the same ornament or pattern upon it and the
mandril that is required to be impressed upon the metal is by means of a screw or
any other power convenient pressed tight up to the mandril which is fixed between
the centres of the lathe and by the usual process carried round as the lathe is set
in motion aud that part of a lathe known as the saddle and tool rest which is
moved along the bed by means of the guide screw as made fast to it the said roller
or milling tool and being geared the same pitch as the grooves cut in the mandril,
by the guide screw, in the case of using an ordinary lathe, or by a similar screw in
the case of a special machine, this said roller or milling tool together with the said
spit or mandril forms a pair of rolls through which the metal is passing and by this
means having impressed upon it whatever ornamental or other patterns are upon
the said roller or milling tool and the mandril, for the convenience of the process
I work my lathe, when a lathe is used, backwards or in the opposite direction to
that usual or the top of the mandril as it is fixed between the centres is going away
from you as you stand in front of the lathe.
I do not confine my invention to the half round or belcher pattern bracelets or
bangle bracelets, but I apply my said invention to the figuring of those that are
flat on the outer side, or any other shape convenient, the only necessary difference
being the making of the draw plates and mandrils and rollers or milling tools all
the same necessary and convenient shape required.
I also have a method of ornamenting and impressing patterns on bracelets and
bangle bracelets by passing the metal between a pair of rolls the required shape
and width having the ornamental pattern required impressed upon them, these
rolls being fixed in a convenient place between the draw plate and the mandril, so
that the metal is drawn into the shape required and then passing through this said
pair of rolls is ornamented or figured before being wound upon the mandril instead
of as in the former method being ornamented or figured at the same time as
winding.

BENJAMIN EDWARD HALFORD now of 47 Alston Street Ladywood Birmingham
in the County of Warwick, Jeweller do hereby declare the nature of my invention
for BRACELETS AND BANGLE BRACELETS AND THE METHOD OF MANUFACTURING
THE SAME, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
For impressing upon Bracelets and bangle bracelets any ornamental pattern or
figure in the same process, that it is drawn and wound, that is, of drawing the
metal into required shape, then bending or winding to the size required to go round
the arm, and impressing any kind of ornamental pattern or figuring on the metal
all at one process, which can be done either in an ordinary screw cutting lathe or
in a machine specially made and adapted for it, my invention is to be applied to
any kind of flat rolled metal, such as gold, silver, german-silver, copper, brass and
all other similar kinds used in Jewellery, in using the metal for my process and
invention it is cut into strips the required width, then being drawn through what
is known as a draw plate, which is a piece of steel having a hole piercing it the
shape the metal is required, the most common shape being half-round or belcher
with the edges of the metal turned into a wire or small tubes, this said draw plate
is fixed in a frame or. holder which is fixed in the tool rest of the saddle of the
lathe, after passing through this plate, the metal is then wound round a spit or
mandrill fixed between the centres of the lathe, which mandrill is screw cut with
two grooves so as to allow the two wires or small tubes edges on each edge of the
metal to fall into these spaces or grooves so cut away as the metal is being wound
on to the mandrill, whilst the centre part between the two grooves cut in the
mandrill, (and which will be of different widths according to the width of the
bracelet or bangle,) stands up, the top side being rounded sufficient to keep the half
round part of the metal full up to the required shape. Now I purpose with my
invention putting or impressing any ornamental pattern on the centre half round
part of the bracelet or bangle bracelet, by impressing the same pattern upon the
raised part of the mandrill, or that part between the two grooves, by means of
what are called milling tools or small rollers, agreeing in shape with the raised part
of the mandrill and having the pattern cut or engraved or embossed upon them so
that when the metal is drawn through the plate and wound upon the mandrill this
said milling tool or roller with the same ornament or pattern upon it and the man-
drill that is required to be impressed upon the metal, is by means of a screw or any
other power convenient pressed tight up to the mandrill which is fixed between the
centres of the lathe, and by the usual process carried round as the lathe is set in
motion and that part of the lathe known as the saddle and tool rest, which is moved
along the bed by means of the guide screw as made fast to it the said roller or milling
tool and being geared the same pitch as the grooves cut in the mandrill, by the
guide screw in the case of using an ordinary lathe, or by a similar screw in the case

page_text: of a special machine, this said roller or milling tool together with the said spit or
mandrill forms a pair of rolls through which the metal is passing and by this means
having impressed upon it whatever ornamental or other patterns are upon the said
roller or milling tool and the mandrill, for the convenience of the process I work
my lathe, when a lathe is used, backwards or in the opposite direction to that usual
or the top of the mandrill as it is fixed between the centres, is going away from
you as you stand in front of the lathe.
I do not confine my invention to the half round or belcher pattern bracelets or
bangle bracelets, but I apply my said invention to the figureing to those that are
flat on the outer side; or any other shape convenient, the only necessary difference
being the making of the draw plates, and mandrills and rollers or milling tools all
the same necessary and convenient shapo required.
I also have a method of ornamenting and impressing patterns on bracelets, and
bangle bracelets by passing the metal between a pair of rolls the required shape
and width having the ornamental pattern required impressed upon them, these
rolls being fixed in a convenient place between the draw plate and the mandrill, so
that the metal is drawn into the shape required and then passing through this said
'pair of rolls is ornamented or figured before being wound upon the mandrill instead
of as in the former method being ornamented or figured at the same time as
winding.
I now proceed to describe my invention as shown and illustrated in the accom-
panying drawings consisting of 6 Figures.
Fig. 1 Is a plan, showing such parts of an ordinary screw cutting lathe as
necessary to illustrate my invention. a. is the bed. b the saddle. c the slido rest.
d the tool box or holder in which a cast frame is held by the screw t and made a
shape that is suitable to hold the draw plate e through which the metal fis drawn
to make it the size and shape of the bracelet or bangle bracelet required before it is
wound upon the screw cut mandrill or spit g which has milled or impressed upon
the raised or rounded part any pattern required to be impressed upon the bracelet
or bangle bracelet, the roller or milling tool h which is figured to correspond with
the mandrill or spit g and fixed in the holder n by the screws 8, and is forced or
pressed against the metal after it is wound round the mandrill or spit by the
screw of the slide rest c, by which it is also released and drawn away when the
work is finished. In the process of drawing and figuring my bracelets and bangle
bracelets, the lathe is worked in the opposite direction to that which it is usually
worked, and the guide screw k propells the saddle b along the bed a at the required
speed according to the width of the bracelet. or bangle bracelet by the ordinary
process of the change wheels. The cast frame or holder as shown and illustrated
in Figs. 1, 2, 3, as a flange or kind of three sided frame m, at the front or that end
nearest the mandrill or spit, against which the draw plate e takes resistance when
the metal is being drawn through it, the holder also as a socket or hole n in
which the roller or milling tool holder o is held, and this said frame or holder Z is
fixed in the tool rest d of the lathe, by the screws t.

Fig. 2. Is a side elevation of Fig. 1, showing the hole u in the draw plate e
through which the metalf passes to be made the shape required.
Fig. 3. Is an end elevation showing the spit or mandrill g and the guide screw k
in section at line p. q. in Fig. 2.
Fig. 4. Is a plan of another process of figuring the Bracelets or bangle bracelets
after they are drawn the required shape but before they are wound upon the man-
drill or spit g. which in this case is plain and not milled or figured as shown in
Fig. 1 and 2, in this process the metal passes between a pair of small rollers h
which are figured with the pattern required to be impressed upon the bracelet or
bangle bracelet and placed between the draw plate e and the mandrill or spit g
upon which the metal f is wound, the necessary pressure on the rolls h is applied
by the pins r, the motion of the lathe in this process is the same as in the former
one, and the width of the bracelet is regulated in the same way by the guide screw
of the lathe.

described process, showing in part dotted lines the figured rollers h in position with
the resisting flange m, and the draw plate e and the metal f as passing through
and being wound upon the mandrill or spit g which is shown in section at line p. q.
in Fig. 4.

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
1st The process of drawing into any shape and width required and winding or
bending to the size of arm that kind of Jewellery known as Bracelets and bangle
bracelets and impressing upon them any ornamental pattern or figuring in one
process.
2nd The method of impressing the ornamental patterns or figuring on that kind
of Jewellery known as Bracelets and bangle bracelets by having the said pattern or
ornament impressed upon a screw cut spit or mandrill upon which they are wound
and by having a corresponding patterned or ornamented roller or milling tool and
together forming a pair of rolls between which the metal passes and receives the
said pattern or ornamenting.
3rd The method of impressing the ornamental patterns or figuring on that kind
of Jewellery known as Bracelets and bangle bracelets by the metal after it is drawn
into shape passing between a pair of rolls any width or shape with the required
pattern or ornament impressed upon them.
