Fig. 6, is a side elevation showing my invention applied to a "retouching
desk.
According to my invention I employ a lantern A having a screen B, which acts
as a reflector, made of white or ground glass or other suitable material at one end,
and a hinged door C with a reflecting surface at the other end. Also a reflector D
composed of plain glass held in a metal frame, adapted to slide in and out of the
lantern A, may be employed, as shown in Figs. 1, and 2, either with or without the
reflector in connection with the hinged door, as aforesaid.
Underneath the said lantern is a lamp E (or a gas burner may be used) Bo
arranged that the light is directed or given off by it in the inside of the said
lantern A, the reflector D and screen B throwing the light through the negative
or print and revealing its flaws and defects.

page_text: If preferred, the screen B may be in the form of a lens, as shown in Fig. 3.
The said apparatus may be fitted to slide in and out of a stand F, see Fig. 4, by
means of ledges G and projection or rim H around the lantern A, or it may be
held by resting upon the flange J of the lamp E, as shown in Figs. 1, and 2, and
by means of pillars K carried by stands L. N are air holes for admitting cold air
to the screen B and reflector D.
My said means or apparatus is placed upon or in connection with an ordinary
"retouching desk," see Fig. 6, in which is the retouching desk, A the lantern,
B the reflecting screen, D the reflector, E the lamp, L the lamp stand, and N the
cold air holes to the inside of the lantern; and its use thereon will be readily
understood by those skilled in the art, without further explanation.
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 :-
1. Means or apparatus whereby photographers can retouch their negatives or
prints with the aid of artificial light, such as shown and described.
2. A retouching lamp for the use of photographers, consisting of a lantern A,
screen B, reflector D, and lanp or burner E, such as shown and described.
