PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Bombillas.
I HENRY ROBERT BARTON, of Goldthorn Villa, Aldridge, in the County of
Stafford, Manufacturer, do hereby declare the nature of this invention to be as
follows:
This invention relates to the manufacture of the bowl portion of bombillas.
This bowl portion consists of a front "plate" part and a back "bowl" part, both
of which have a number of perforations made in them. These two parts are usually
made separately, the one being partly dished around its edge to receive the other,
and then the two are soldered together forming an interior chamber between the
two. At the one side of these two parts, they are extended and formed into a
tubular nozzle or pipe, which may now be connected up to a tube or mouthpiece
of any suitable or desirable length or shape.
In my improved method of manufacture we proceed as follows:-I cut out one
blank at one operation from which both the front plate and the bowl portion may
be simultaneously made. This blank is now submitted to stamping tools by which
the parts are dished, cupped or otherwise shaped, according to each respective
part.
These tools are duple in form, that is the "front plate" and the "bowl"
with their respective half shanks are shaped at the same operation. In thus
shaping these parts the tools are so arranged that the outer end of the bowl and
that of the plate are contiguous to each other, and having a short connecting
portion of metal left intact thereat, so that at such part, the metal may be
subsequently bent over and the two parts fall fair upon each other. Both these
parts are again pierced at the same operation by duple piercing tools, thus again
doing in one operation what is usually done in two.
Similarly both of these two parts are simultaneously clipped, that is, the surplus
metal around the edges is removed at one operation. The metal is now bent over
at the junction before named, and the edges of the bowl part lie within the raised
edge of the plate part. These are now placed in closing tools which neatly close
down the raised edge of the plate part tightly over the edge of the bowl, and thus
the two are firmly united. Any desirable or suitable stem or mouthpiece may now
be attached to the tubular shank in the ordinary manner.
Thus by means of this duple tool arrangement, and the connecting strip between
the two parts, four operations of the ordinary method are saved, that is, I now
accomplish in four operations what has hitherto required eight, and at the same
time produce a much neater article.
The order of operations subsequent to the cutting out of the blank may be varied
if desired.

I HENRY ROBERT BARTON, of Goldthorn Villa, Aldridge, in the County of
Stafford, Manufacturer, 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 :—
This invention relates to the manufacture of the bowl portion of bombilloas.
This bowl portion consists of a front "plate" part and a back "bowl" part, both
of which have a number of perforations made in them. These two parts are usually
made separately, the one being partly dished around its edge to receive the other,
and then the two are soldered together forming an interior chamber between the
two. At the one side of these two parts, they are extended and formed into a
tubular nozzle or pipe, which may now be connected up to a tube or mouthpiece of
any suitable or desirable length or shape.
In my improved method of manufacture I proceed as hereinafter described, and
in order to more clearly explain this my invention, and the manner in which it is
performed I have appended hereunto an illustrative sheet of drawings upon which
are figures and numbers of reference, similar numbers referring throughout the
several views to the same thing or part, and in which :-
Figs. 1 and 2, are views of the double blank from which the bowl is made.
Figs. 3 and 4, show the same after it has been dished and shaped, ready for
folding together.
Fig. 5, is a view of the bowl after being put together.
Fig. 6, is a sectional view of the bowl on line A-B Fig. 5, before the edges are
closed over.
Fig. 7, is a sectional view of the bowl on line A-B Fig. 5, after the edges have
been closed down.
Fig. 8, is a side view and Fig. 9 a plan view of a bombilloa made according to
this my invention.
I cut out in one blank the two parts 10, and 11, which parts respectively form
the front plate and bowl portion of the bombilloa. This blank is now submitted to
stamping tools by which the parts are dished, cupped or otherwise shaped,
according to each respective part, as seen in Figs. 3 & 4, the part 10 being shaped
for the upper plate 10, and the part 11, being dished to form the bowl 11ª. These
tools are duple in form, that is the "front plate" 10%, and the "bowl" 11ª, with
their respective half shanks 12, and 12ª, are shaped at the same operation. In
thus shaping these parts the tools are so arranged that the outer end of the bowl
and that of the plate are contiguous to each other, and having a short connecting
portion of metal at 13, left intact thereat, so that at such part, the metal may be
subsequently bent over and the two parts fall fair upon each other, as shown in
Figs. 5 & 6. Both these parts 10 & 11 are pierced with holes 14, at the same
operation, which operation is preferably done while the metal is in its flat condition
as seen in Figs. 1 & 2, by duple piercing tools, thus again doing in one operation
what is usually done in two.
Similarly both of these two parts 10%, and 11ª, are simultaneously clipped, that
is, the surplus metal around the edges is removed at one operation. The metal is
now bent over at the junction 13, before named, and the edges 15, of the bowl
part 11, lie within the raised edge 16, of the plate part 10°. These are now placed
in closing tools, which neatly close down the raised edge of the plate part, tightly
over the edge of the bowl, as seen in Figs. 5, 7, 8 & 9, and thus the two are firmly
united. Any desirable or suitable stem or mouthpiece 17, may now be attached to
the now formed tubular shank 18, in the ordinary manner.

page_text: Thus by means of this duple tool arrangement, and the connecting strip 13,
between the two parts 10 & 11°, four operations of the ordinary method are saved,
that is, I now accomplish in four operations what has hitherto required eight, and
at the same time I produce a much neater article.
The order of operations subsequent to the cutting out of the blank may be varied
if desired.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the manufacture of bombilloas, the double method of cutting out, piercing
and dishing and shaping of the parts by means of double tools under simultaneous
action as here described and shown upon the drawings.
2. The manufacture of bombilloas, from a double blank, consisting of the parts 10
and 11, having the connecting bar of metal at 13, as and for the purposes herein
described and shown.
