THOMAS WATLING SHORT and WILLIAM JAMES MASON trading as Short and
Mason Scientific Instrument Manufacturers 40 Hatton Garden E.C., Co. Middlesex,
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 :-
Our Invention relates to Aneroid Barometers having visible works and which are
provided with transparent Glass dials, & having internal Reflectors for the purpose of
illuminating the Graduations and Indications printed upon the Dial, as well as for
showing clearly the positions of the Hands-and consists in the adoption of the
following substances for the construction of the said Reflectors namely Card,
Clay, Porcelain, Opal Glass Xylonite or similar non corrosive substances other
than Metal.
The accompanying Drawings forming part of this Specification are to be referred
to wherein Figs. 1. 2. 3. & 4 represent Sections of the different forms of Reflectors
used by us and Fig. 5 represents a complete Section of the particular form of
Barometer with the Reflector in position-We do not confine ourselves to these
particular curves-they may be varied to suit the size of the Instrument-the diameter
of the Dial or the contour of the wood or Metal frame in which the Instrument is to
be mounted or fitted-Nor is it of necessity that these Reflectors be all white-
they may be wholly or partially tinted-and with either dead, matted, or glazed
surfaces.
DESCRIPTION OF FIG. 5.
Fig. 5 shows the section of a Barometer with the Reflector in position-as mounted
in a wood or Metal frame-A A A represents the frame. B the inetal plate on which
the Barometer movement is mounted C. C. C is the Barometer movement-D D the
transparent Glass Dial Ę E the Bezil holding the Glass, and R R the Reflector
surrounding the movement.
Having now particularly described and ascertained the nature of our said Invention
we declare that what we claim is
A Barometer wherein the works and the transparent Glass dial are illuminated by
means of a Reflector or Bason constructed of Card-Clay-Porcelain, Opal Glass,
Xylonite, and non corrosive substances other than Metal as and for the purposes
specified.
