Improvements in Fuses and in Sights for Fire Arms, and in the
Method of Marking the same.
I, THOMAS REEVES, of 36, Unett Street, in the City of Birmingham,
Enameller, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to render more legible the figures, lines or other
markings on fuses and on the sights of fire arms. This, as applied to the sights of
fire arms, I effect by enamelling in white the said figures, lines or other markings,
the body of the sight being oxidized or otherwise made dark. The enamel is sunk
into the face of the sight so that the markings are indelible and being white in
contrast to the body of the sight they can be seen much more clearly than when
they are merely cut or stamped in the surface of the sight as heretofore.
My improved method of enamelling the said markings on the sights is as
follows:-
I make a composition of some or all of the following ingredients in somewhere
about the proportions given below viz. :—
Ground glass
Arsenious acid
Putty
Carbonate of barzola
Red lead
Nitrate of lead
Borax
White lead
Oxide of tin
20 parts by weight,

1 part by weight,

"
"
1 part by weight,
4 parts by weight.
These ingedients are mixed together and ground with sufficient water to make a
stiff paste.
The sight to be marked (made of steel as usual) having its lines and numbers
cut out to the proper depth, is heated sufficiently to burn up all foreign matter
and when the sight is cold the said composition is laid on the markings and then
the sight is again heated so as to fuse the whole of the mixture and cause it to
adhere to the sight. The superfluous white enamel is then removed by filing or
grinding until the white markings appear which will be a dead white. If the
markings are required to be glossed the sight with its white marks formed as
above described is again heated until the desired gloss is acquired.
I do not confine myself to the proportions of the ingredients given above as
they have to be varied according to the nature of the steel and the hardness of the
enamel required. For instance if the steel is very hard I increase the quantity of
red lead and white lead; or if the enamel is required to be not quite so hard as
when made with the proportions given I use a smaller quantity of ground glass.
Nor do I restrict myself to using all the ingredients as I find that some of them
may be dispensed with without materially affecting the result.
My invention is applied to fuses similarly as above described with reference to
the sights of fire arms.

Improvements in Fuses and in Sights for Fire Arms, and in the
Method of Marking the same.
I THOMAS REEVES of 64 Spencer Street in the City of Birmingham Enameller
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 this invention is to render more legible the figures lines or other
markings on the sights of fire arms, ordnance and other munitions of war in which
sights are used. This as applied to the sights of fire arms, I effect by enamelling
in white the said figures lines or other markings, the body of the sight being
oxidized or otherwise made dark. The enamel is sunk into the face of the sight
so that the markings are indelible and being white in contrast to the body of the
sight they can be seen much more clearly than when they are merely cut or stamped
in the surface of the sight as heretofore, as per drawing.
My improved method of enamelling the said markings on the sights is as
follows.
I make a composition of some or all of the following ingredients in somewhere
about the proportions given below viz. :
Ground glass
Arsenious acid
Putty
Carbonate of barium
Red lead
Nitrate of lead
Borax
White lead

-
1 part by weight,
Oxide of tin
4 parts by weight.
These ingredients are mixed together and ground, and calcined until the whole
becomes an opake white, and afterwards ground with sufficient water to make a stiff'
paste.
The sight to be marked (made of steel as usual) having its lines and numbers
cut out or stamped to the proper depth is heated sufficiently to burn up all foreign
matter and when the sight is cold the said composition is laid on the markings and
then the sight is again heated so as to fuse the whole of the mixture and cause it
to adhere to the sight. The superfluous white enamel is then removed by filing or
grinding until the white markings appear which will be a dead white.
If the markings are required to be glossed the sight with its white marks formed a
as above described is again heated until the desired gloss is acquired.
I do not confine myself to the proportion of the ingredients given above as
they have to be varied according to the nature of the steel and the hardness of
the enamel required. For instance if the steel is very hard I increase the quantity
of red lead and white lead or if the enamel is required to be not quite so hard as
when made with the proportions given I use a smaller quantity of ground glass..
Nor do I restrict myself to using all the ingredients as I find that some of them
may be dispensed with without materially affecting the results.
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 4
claim is
(1.) Enamelling sights for tire arms and such like by the foregoing method as
described.
