Improvements in the Manufacture of Bells or Funnels for Lamps
or Lanterns, Tundishes, and the like.
JOHN WATHEN, 120 Barford Street Birmingham, Stamper and Piercer,
WILLIAM HENRY WATHEN, 120 Barford Street, Stamper and Piercer, both
in the County of Warwick and the City of Birmingham, do hereby declare the
nature of this invention to be as follows:-
The production of that part or portions of lamps or lanterns, tundishes &c.
called the bell or funnel out of tin-plate or other suitable material, entirely by
machinery & in one piece & without join or seam, instead of as formerly by hand
or in part by mechanical devices & with seams or of more than one piece, in the case
of the former articles, by our improvements, the reflector and bell are in one piece.
To attain the object of our invention we construct in the ordinary manner series
of tools or dies in which are formed with great exactitude, cavities of the required
shape or contour for the production of bells or funnels of the various patterns or
configuration suitable for the purposes specified.

Improvements in the Manufacture of Bells or Funnels for Lamps
or Lanterns, Tundishes, and the like.
JOHN WATHEN, 120 Barford Street Birmingham in the County of Warwick,
Stamper and Tool Maker, WILLIAM HENRY WATHEN, 120 Barford Street,
Birmingham, in the County of Warwick Stamper and Tool Maker, 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 object of our invention is the production of that part or portion of lamps or
lanterns, tundishes and the like called the bell or funnel out of tin-plate or
other suitable material entirely by machinery and in one piece without join
or seam, instead of as formerly by hand or in part by mechanical devices and with
seams or of more than one piece, and further in the case of the former articles, by our
improvements, the reflector and bell are in one piece.
To attain the objects of our invention we construct in the ordinary manner
series of tools or dies in which are formed with great exactitude, cavities of the
required shape or contour, for the production of bells or funnels of the various
patterns or configuration suitable for the purposes specified. A further advantage
is that the bells and the like produced according to our said invention are of
perfectly smooth surface fit and ready for receiving the very high polish necessary
to reflectors whereas other and known means cause the metal to become too rough
to polish.

page_text: Figure 1 of the accompanying drawings represents partly in vertical elevation,
and partly in section, the side view of a lamp or lantern with the bell a, constructed
according to our said invention, and having holes b. 61 therein for the insertion &
ventilation of the flame of the lighted lamp.
Figure 2 shows a front elevation of same.
Figure 3 shows a funnel or tundish, a being the portion constructed according
to our invention.
Figure 4 represents an elevation of a pan out of the first die or tool, the cavity
in the said die or tool being exactly of the requisite conformation to produce the
necessary form.
Figure 5 shows in sectional elevation the successive stages, or courses the pan
Fig. 4 passes through in the series of dies or tools, all constructed to the greatest
exactitude and according to the various sections represented at c. d. e. f. g. h. i. k
and l.
Figure 6 shows in vertical elevation the completed bell, the bottom being cut out
at m, for use in ordinary lamps.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is :-
In bells or funnels for lamps or lanterns tundishes and the like, producing same
all in one piece without join or seam, and of perfectly smooth surface, fit and ready
for receiving the high polish necessary for reflectors, substantially described and
set forth.
