Improvements in and connected with Photographic Cameras.
CHARLES HENRY ADKINS Civil Engineer 28 Orrell Lane Aintree near
Liverpool do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved receptacle for containing the sensitizied
plates used in the photographic process, to be called the magazine such magazine
being capable of being completely reversed withdrawn or tilted backward or forward
by means of a surrounding frame the sensitizied plates after use being propelled
forward by a spring and released by a drawbar permitting the whole of the used
plates to fall individually into one of the above described magazines empty and
placed horizontal, also this said magazine is used in conjunction with a special box
or camera of my own design which upon the magazine being removed admits of an
improved method of applying a ground glass screen for focussing, which is with-
drawn and turned vertically in the position previously occupied by the sensitizied
plates when in the magazine previous to use. The above improvements I claim
admit of the entire operation of renewing the supply of sensitizied plates in
daylight or other actinic light thus obviating the necessity of a dark room.
claim from the whole of my invention in combination the formation of a complete
hand or stand photographic camera with improved arrangement for obtaining
direct focus on to the ground glass screen also possessing improved magazine
facilities.

Improvements in and connected with Photographic Cameras.
CHARLES HENRY ADKINS, 28 Orrell Lane Aintree near Liverpool,
Engineering Surveyor, 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 features of my invention are as follows
1st. To be able to obtain an improved hand or stand photographic camera equally
useful in either form and capable of the following facilities.
2nd. To be able by means of the magazines (which have been previously charged
in a non-actinic light) to recharge with sensitizied plates or films such camera under
any circumstance of light and condition and to remove by means of the magazines
the plates or films from same after use.
3rd. To be able to transfer the said plates or films singly after use from one
receptacle to another without the removal of the receptacles.
4tb. To be able to move the upper receptacle backward or forward and maintain
in a light proof condition the lower receptacle.
...
:
The diagrams illustrating the above features are shewn on sheet numbered 1 by
A longitudinal section Fig. 1.
:

page_text: 1st. Two boxes similar to each other in size form and construction, with sliding
doors H, and are No. 1 and 2 on the drawing to be called the receptacles or
magazines.
2nd. Metal carriers for holding the plates or films A.
3rd. Release arrangements in front of carriers to allow a forward movement by
the drawing out or sliding in of the piece B.
4th. Two side pieces of material in front of carriers to act as guides for the
carriers C.
5th. A surrounding square frame to hold the receptacles & focussing screen to
give a tilting movement backward or forward if required D.
6th. A frame enclosing a screen for focussing such frame being attached and
running in a groove E.
7th. An outer casing enclosing the whole of above F which forms the
camera.
8th. A spring G.
9th. A strip of material attached to the inside of magazine B¹.
The purpose of such parts are as follows
1st. The No. 1 receptacle or magazine is constructed for the purpose of holding
the sensitizied plates or films used in photography, each of these plates or films
being placed in a separate holder or carrier A, these carriers are filled & placed
in a non actinic light in No. 1 receptacle in a vertical position one behind the
other, and are held upright by a spring G at the back, and catches or releases B
on the front, these being moved mechanically. The spring at the back G propelling
the carriers forward.
The sensitizied plates or films in this magazine are secured from light by a sliding
door to same H.
2nd. No. 2 magazine is similar in every respect to No. 1 but is placed when in
use in the first instance in a horizontal position empty and immediately underneath
No. 1 magazine which is full or partially so.
f
3rd. The surrounding square frame D into which the magazine & focussing
screen. fit is for the purpose of tilting the magazine backward or forward & is
désigned to be light proof at the lower joint when so moved.
4th. The side guides C are flat pieces of material lipped on two of the outer
edges to prevent the carriers when liberated from falling out of position.
5th. E is a frame enclosing the screen for focussing such frame being attached
and running in a groove.
The operations of the above parts are as follows
:
When the No. 1 charged magazine is placed in the vertical position, and the
No. 2 empty magazine is placed in the horizontal position, the sliding doors H to
each are withdrawn, the carrier in No. 1 magazine is released and permitted to be
pushed forward by the spring G, and by gravitation falls downward on to the
lipped side guides C which being on an incline causes it to fall forward at the top
and slide down such guides, into No. 2 magazine which is empty,
When in use as a hand camera this operation can be repeated without
interruption until the whole of the plates or any number of same are transferred
from No. 1 into the No. 2 or lower magazine, but if at any time during the period
of use it is desired to obtain a direct focus of the object to be photographed or in
other words used as a stand camera, it can be, by means of the screen E' provided
for such purpose, the operation for so doing being as follows;
4
The sliding door H of No. 2 magazine is first closed thus securing the plates or
films therein from the action of light, the sliding door H of the first or No. 1
magazine is then closed allowing it to be, bodily removed & admitting of the
focussing screen E being drawn along the groove provided for so doing, and turned
down into the surrounding frame D, taking a vertical position' similar to that
. occupied by the plate and carrier in No. 1 magazine when replaced, after focussing

page_text: this screen is lifted up and pushed into its original position allowing the No. 1
magazine to be replaced, the sliding doors re-withdrawn, the exposure made, & the
used plate or film transferred from No. 1 to No. 2 magazine as above described, if
during the focus a movement backward or forward is required it is done by
Blackening two side screws which pass through the sides of the outer casing F into
the surrounding frame D, thus permitting its movement, the desired position being
maintained by tightening the screws.
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
That the features of novelty consists
1st. In an improved arrangement of two detachable receptacles or boxes called!
the magazines to be used for the purpose of holding the sensitizied plates or films,.
used for photographic purposes, such arrangement admitting of the said plates or
films being emptied out of one magazine and received into another similar magazine,.
the operation for so doing being performed mechanically, and admitting of the
complete removal, renewal or re-arrangement in daylight or under any other
circumstance, of either or both magazines.
Dated this 25th day of March 1896.
