PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Bells.
I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of 4, Corporation
Street, Manchester, in the County of Lancaster, Patent Agent, do hereby declare the
nature of this invention, which has been communicated to me from abroad by
R. Daban Fréres, of 15, Boulevard Saint-Denis, Paris, in the Republic of France,
Manufacturers, to he as follows:-
This invention relates to improvements in the manufacture of bells principally such
as are carried by animals or formed with a handle and has for its object to cut,
stamp or block same in one or two parts from sheet metal, the joint formed being
afterwards united.
When giving the bell a round shape it is formed in two halves and with a rim
which serves for fastening the same together. When giving the bell a conical shape
it is formed in one piece, the top in this and the round shape being furnished with
a small handle formed of a strip of sheet metal folded up, the lower part of which
is inserted into the bell, split and soldered to the interior thereof whilst the outer part
may be formed with slots for the reception of a strap.
The bells formed as described and provided internally with the tongue covered with
paper and earth, are placed, also enveloped with paper, upon a layer of clay mixed
with straw and separated from each other by means of strips of the same inaterial.
In and between the joint of each bell are then placed a few grains of copper and the
whole covered with four or five other layers of clay mixed with straw and the cake
thus formed exposed for three-quarters of an hour to a temperature of 1800 degrees,
after which the said cake is thoroughly shaken, the superfluous copper withdrawn
through an opening previously formed therein for that purpose and the cake plunged
into water.
The clay is then removed from the bells and the latter cleaned, the joints having
become united by the said copper mixing with the sheet metal when soft whilst
exposed to the heat described.
The bell thus formed is very strong, durable and has a clear ring.

Improvements in the Manufacture of Bells.
I, FERDINAND BOSSHARDT, of the Firm of F. Bosshardt & Co., of 4, Corporation
Street, Manchester, in the County of Lancaster, Patent Agent, do hereby declare the
nature of this invention, which has been communicated to me from abroad by
R. Daban Freres, of 15, Boulevard Saint Denis, Paris, in the Republic of France,
Manufacturers, 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 improvements in the manufacture of bells, principally

page_text: such as are carried by animals or formed with a handle and has for its object
to cut, stamp or block same in one or two parts from sheet metal and braze same
together so as to be perfectly strong, sonorous and replace advantageously cast bells
which are heavy and brittle.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is an elevation of a round bell and Fig. 2 a plan thereof.
Fig. 3 an elevation and Fig. 4 a vertical section of a conical bell.
Fig. 5 an elevation and Fig. 6 a plan of a modification of the bell shown in
Figs. 1 & 2.
In carrying out this invention and referring to Figs. 1 & 2 I form this shape of
bell of sheet metal in two semi-spherical parts with holes and slit of different shapes
according to the sound to be obtained when secured together at their bases ó which
aro adapted to fit into each other and form a slight beading around the bell. At
the top of the bell is formed a shank having a hole which facilitates its
attachment. When the bell is secured by means of a strap I employ a shank d
shaped as shown in Figs. 3, 4, 5 & 6. This shank is formed in T fashion of sheet
metal doubled and brazed to the interior of the bell and its upper part arched and
formed with slots at e for the reception of the strap. The bell f is formed of one piece
of sheet metal bent to the required shape.
The brazing of the bells is performed as follows ;-
The tongue of the bell covered with paper and earth is placed into the bell which
is also enveloped with paper. after having introduced between the joint a few grains
of copper. A certain number of bells thus prepared are then placed upon a layer of
clay mixed with straw or hemp after which they are separated by strips also made of
clay in such a manner that each is situated in a compartment. A few grains
of copper are then placed into each compartment and the same covered by four or five
other strips of clay to form a cake which is put in an oven to be dryed. The said
cake is exposed for. three-quarters of an hour to a temperature of 1800 degrees
centigrade at which the sheet metal becomes very soft and alloys with the aforesaid
copper thus making the bell very strong and sonorous.
The cake is then withdrawn from the oven, inclined and turned over in all
directions and the copper not absorbed thereby dropped out through an opening
formed previously in the cake after which it is plunged into a basin of water.
The cake is then broken up, the bells removed, cleaned and dryed.
Imperfections which might occur such as granulations and the like disappear when
being polished. The bells may also bo nickled, silvered or gilded and provided with
means for rendering the tongue h inactive by placing the eye of the latter into one
of the holes at the top of the bell and a bar y, see Figs. 2, 5 & 6, through the same
which prevents the tongue from moving.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is-
A bell formed in parts of sheet metal cut out, stamped or blocked and afterwards
brazed together, all substantially as and for the purpose set forth.
