IMPROVED BELL, DOME, GONG OR ALARUM FOR TELEGRAPHIC, TELEPHONIC AND "AN LIKE PURPOSES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, GEORGE WATTS of N° 25 Smith Street Clerkenwell in the County of
Middlesex Engineer do hereby declare the nature of my invention for
IMPROVED BELL, DOME, GONG OR ALARUM FOR TELEGRAPHIC, TELEPHONIC AND
"AN
LIKE PURPOSES to be as follows:―
The object of my invention is to simplify the construction or casting of bells
domes or alarums for telegraphic telephonic and other like purposes and consists in
casting the bell dome or alarum in one piece of a circular shape and by the
inversion of the top or cone the base of the inversion forms the standard by means
of which it can be fixed or fastened to any foundation by a screw or otherwise
through a thread at the bottom of the inverted cone or base.
This apparatus may be cast solid at the top without forming the inverted cone
and fastened to the foundation by the standard by means of a screw passing
upwards from the foundation through this standard but I prefer casting it inverted
or hollow in the top centre as by this method I obtain a more distinct and acute
sound and also effect a great saving in the expense of manufacture.—The apparatus
may be struck or sounded by any of the means now in use.

GEORGE WATTS of N° 25 Smith Street Clerkenwell in the County of Middlesex
Engineer do hereby declare the nature of my invention for "AN IMPROVED BELL
DOME, GONG OR ALARUM FOR TELEGRAPHIC TELEPHONIC AND LIKE PURPOSES,"
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 my invention is to simplify the construction or casting of bells,
domes, or alarums for telegraphic, telephonic and other like purposes, and consists
in casting the bell, dome, gong or alarum in one piece of a circular shape and by
the inversion of the top or cone the base of the inversion forms the standard by
which it can be fixed or fastened to any foundation by a screw or otherwise through
a thread at the bottom of the inverted cone or base.
This apparatus may also be cast solid at the top without forming the inverted
cone and fastened to the foundation by the standard by means of a screw on its
own standard or passing upwards from the foundation, but I prefer casting it
inverted or hollow in the top centre as by this method I obtain a more distinct and
acute sound and also effect a great saving in the expence of manufacture. The
apparatus may be struck or sounded by any of the means now in use.

DESCRIPTION OF DRAWING.
Fig: 1 shews a section of the apparatus with the inversion A forming the
standard B with a screw or other fastening C.
Fig: 2 also shews a section of the apparatus cast solid at the top A, and forming
the standard B with a screw cast at the base of the standard C.
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
The formation of the bell, dome gong or alarum so that the inversion or stem
forms a standard by means of which it can be secured to any foundation.
