Mr. T. C. Roach, Familiarity known by pho
togIaphers AL over the United States and
even in Europe ms ''the old man. Is recog-
nized by them as a sort Of mahatma, one
who II he does not quite "know 1t all" is
very liabe to find out anything more that IL
30 III discovered lie has taken out greater
number Of patents ia photography than any
body else in this country. Speaking recently
OF the practical applications OF photography
In late years, he said 10 "a reporter:
"Do you know that watch dials are now
made by photography at a mere fraction OF
their former costi They all used TO be painted
BY hand Now hundred are made in the
time formerly required to produce one, and
each OF the hundred is better than the one
would have been The dial is Of copper COW
erred with enamel. Upon that they lay a SEN
sitizei coating Of nlbunen and bichromate
of potash. A large drawing, say twelve
inches ina diameter, Of the design, figures, and /
dots that IL Is desired to put upon the dial Is +
I photographed down to the required size, /
which makes II 70 very fine that whatever i
inaccuracies may have been in the drawing |
are almost beyond discovery by the micro
scope. The negative thus made is exposed TO
the light In contact with the gelatine coated
watch dial for from TIRES to i've minutes.
Electric light is just as good as sun light.
Where the light has noted the gelatine Is
made insoluble. The dial is now linked over
with common photographic transfer ink.
Next, with a clean sponge moistened with a
little gum water, the ink and gelatine are
wiped Off the dial from all parts except
where the light has acted, and to those IL adj
here's leaving the design In clear black upon
the enamelcd plate. But that design would
easily blur and rub of by wear. Another
process is necessary TO make IL permanent.
A metallic enamel powder Of any color de-
sired black, blue, red, green, or purple-is
busted upon the dial II sticks to the linked
portions, but nowhere else. Then the dial Is
put In the mufiie aud fired The enamel
powder melts into the white enamel base,
and the work Is complete. The Waltham
. Watch company paid 81 600 for that process.
, By it they can turn out, for ten cents each,
!, dias that ia this old way Of making would
, have cost 81 apiece.
''Speaking of that necessity recalls TO me
the effort now making for tho production, for
purpose OF magazine and book illustration,
printed with type, OF photographs from
nature or paintings, by means OF what are
now called tint glasses. About that | am
going To tell you page Of history that has
! not before been published. and that will make
. |. no small stir among number Of persons who
. arc claiming 10 be the inventors Of processes
. Ia that direction at tho present time. The
real inventor of tint glasses or. as he called
!, them. ruled spcctrums was Baron Won EgloH-
: stein, who patented his processes in the
/, United States and England as long ago as
! 1865. He was brilliant, highly educated
= man, who did great deal OF fine engineering
: work for our government, and who went
a away To Europe several years ago. There
