COMPLETE SPECIFICATION.
Receptacle for Refilling Camera Magazines with Photographic Plates
without the use of a Dark Room.
I, LADISLAS NIEVSKY of 14 Gransden Road, Shepherd's Bush, in the County
of Middlesex, London, W. Photographer do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The general object of this invention is to provide a simple and efficient means for
re-filling the magazine in a magazine camera with plaques or sensitized dry plates
in broad daylight without the use of a dark room. Another and special object is to
further expedite and facilitate the use of my so-called simplex photographic machine
described in the Specification of my Patent dated 19th October 1891 No. 17,860.
By that machine or apparatus each plaque delivered from the magazine to the
camera proper is after being exposed opposite to the lens and the object to be
photographed conveyed into a tank where it is expeditiously and conveniently
developed, fixed and washed, and can then be removed from the tank as a finished
photograph. But by my present invention I do away with the necessity for going
into a dark room each time the magazine has to be refilled and the machine can
thus do much more work in the same number of hours than heretofore, because the
speed at which the machine works is so very great that the magazine has to be
refilled very frequently during a busy day.
Fig. 1 of the accompanying drawings is a sectional side view of the upper part
of the simplex machine and Fig. 14 a detail view of part of Fig. 1.
Fig. 2 is a front view of the machine.
Fig. 3 is a sectional view of the receptacle T for plaques U which are to be
charged into the magazine M without the use of a dark room and
Fig. 4. is a part sectional view of the filling receptacle and of the magazine in
the position of being filled.
It may conveniently be made of tin and has a lid T'. Before being taken into
use for charging the magazine a piece of paper pasted over the opening TX at the
outer end has to be torn off and also the lid T has to be removed. The plaques U
in this box are then transferred to the interior of the magazine without exposure to
the light and yet without the use of a dark room by inserting a finger through the
opening at Tx and pressing upon the pushing plate V, at the same time turning the
camera with the lens end downwards until the last plaque comes just below the edge
of the shutter Q whereupon the shutter is pushed in between the plaques U and
the pusher plate V. The first plaque entered may become a waster because of
momentary partial exposure to the light during refilling but this is of small
importance, it may however if desired be replaced by a dummy plaque not sensitized
and which is returned to the dealer for repeated use.
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 :-
The receptacle T with paper covered hole TX at one end, lid T' at the other end,
and pusher plate V for the purpose of transferring plates U therefrom into a camera
magazine without the use of a dark room, substantially as set forth.
