PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metallic Scales for Ther-
mometers for Brewers' Use, for Baths, and for other like
Purposes.
I, JAMES JOSEPH HICKS of 8 Hatton Garden in the County of Middlesex, Scientific
and Meteorological Instrument Manufacturer, do hereby declare the nature of this
invention to be as follows :-
Heretofore, in the manufacture of metallic scales for brewer's thermometers, the
divisions and figures have been filled in with "black wax," which, when immersed for
a long period in boiling water, or in oil or spirit, is dissolved out of the spaces or
recesses and the scale becomes very difficult, if not impossible, to read.
"
Now, according to my invention, I substitute for the "black wax a paste, or
preparation consisting mainly of black or other colored ground glass or its equivalent.
I first divide the scale in the ordinary manner but I sink the divisions and figures
very deeply in the metal, I then rub in the aforesaid paste so as to fill the spaces or
recesses, after which I submit the scale to a high temperature in a muffle or other
furnace, which has the effect of melting the glass and causing it to become firmly
attached to the metal in the recesses or spaces of the divisions and figures.

described and ascertained, in and by the following statement :-
Heretofore, in the manufacture of metallic scales for brewers' thermometers, the
divisions and figures have been filled in with "black wax," which, when immersed for
a long period in boiling water, or in oil or spirit, is dissolved out of the spaces or
recesses, and the scale becomes very difficult, if not impossible, to read.
Now, according to my invention, I substitute for the "black wax," a vitreous
enamel paste, consisting of black or other colored ground glass, or its equivalent. I
first divide the scale in the ordinary manner, but I sink the divisions and figures very

recesses, after which I submit the scale to a high temperature in a muffle or other
furnace, which has the effect of melting the glass or vitreous enamel, and causing it to
become firmly attached to the metal in the recesses or spaces of the divisions and
figures.
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 :-
