PROVISIONAL SPECIFICATION.
Improvements in Photographic Cameras.
I, JOHN DAVIES MUCKLOW of 260 Camden Road in the County of Middlesex,
Chemist, do hereby declare the nature of this invention to be as follows:
My improved camera is made by inoulding the different parts of various suitable
substances, such as india rubber compounds which form hard and compact materials,.
woodite and other suitable substances.
The different parts may be moulded either with or without the necessary brass
work or other metal fittings, so that when removed from the mould the different
parts will be fitted with its necessary metal work & ready for putting together to
form a complete camera.
The dark slide and all other accessories are likewise moulded.

COMPLETE SPECIFICATION.
Improvements in Photographic Cameras.
JOHN DAVIES MUCKLOW No. 260 Camden Road in the County of Middlesex
Chemist 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 :-
My improved camera is made by moulding the different parts of various suitable
substances such as india rubber compounds which form hard and compact materials,
woodite and other suitable substances.
The different parts may be moulded either with or without the necessary brass
work or other metal fittings, so that when removed from the mould the different
parts will be fitted with its necessary metal work and ready for putting together
to form a complete camera.
The dark slide and all other accessories are likewise
moulded.
•
To enable my invention to be more clearly understood, I will now describe the
same by means of the accompanying drawing in which :-
Fig. 1, is a plan of the lower part of a metal mould.
Fig. 2, is a transverse section upon line A B Fig. 1, but shewing the upper as
well as the lower part of the mould.
Fig. 3, is a plan of the bottom frame of a camera after removal from the mould
shewn in Fig. 1.
In the drawing 1, 2 are respectively the upper and lower parts of a mould of
iron or other suitable metal designed for producing the bottom frame of a photo-
graphic camera 3, as shewn in Fig. 3. The respective parts of the mould are
preferably held in position by a series of pins 4 which may be driven tightly into
holes drilled into the lower part of the mould but fit loosely into corresponding
holes 5, formed in the upper part. The metallic mountings 6, to which the stay
rods, hinges or other parts of the camera are attached are preferably mounted upon
metal pins 7, which are sunk as shown into the metal of the mould and support
the mountings in the horizontal, vertical or other position required. The edges of
the mountings are preferably bevelled in the manner shewn.
Ebonite, woodite, paper pulp, xylonite celluloid or equivalent material in a plastic
or softened condition is now either pressed or run into the grooves 8, within the
Price Gidl

page_text: mould which is weighted or forced together in any convenient manner. The metallic
mountings are thereby enclosed and secured in position by the plastic material
employed which when set, cold, or sufficiently solid is removed from the mould
trimmed, polished, or varnished, and connected by suitable means to its respective
part of the camera, dark slide or equivalent which has been formed in a mould in a
similar manner. If no metallic mountings are required the pins supporting such
are removed from the mould.
It will be understood that the mould employed varies with the parts of the
camera constructed in this manner; my object being to mould the frames, stays,
dark slides and other parts and accessories connected with or forming part of photo-
graphic cameras with or without the necessary metallic mountings as may be most
convenient so that they may be readily put together to form a complete camera or
part thereof of great lightness and strength.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
The construction of the frames and other parts connected with or forming part
of photographic cameras, dark slides, and accessories, of ebonite, woodite xylonite,
paper pulp celluloid or other suitable plastic material, metallic plates being
embeded therein or not as may be required, by the means, for the purpose and in
the manner described.
