1, HENRY GRANT MADAN CONY BEARE, of The Hut, Ingatestone, Essex,
Gentleman, do hereby declare the nature of this invention and in what manner
the same is to he performed to be particularly described and ascertained in and
by the following statement :-
An appliance in accordance with my invention is represented by the drawings
left with my Provisional Specification.
Into this
I employ a flange A to be attached to the camera front by screws.
flange I screw a ring B, having a milled edge. On the inside of this ring are
fixed two or more studs D. To the photographic lens or other tube is attached a
flat ring or flange G having two or more notches cut in the edge as shewn at E and
corresponding with the studs fixed to the ring B. On the surface of the flat ring G
near one or all of the notches I fix a small stud or studs K.
In lieu of the above I make recesses in the screwed ring B as shewn
at F and projecting pieces as at H to the flat ring or flange attached to the lens
tube.
The figure on the left of the drawing is a side elevation and shews the parts A.
and B screwed together. The next figure is a section of the same parts separated
the one from the other. Beyond is a front elevation of the two parts and by the
figure at the right of the sheet the flange around the end of the lens tube or other.
tube is shewn. Beneath these are two other figures which represent the modifica-
tion. In its application to a camera,, the lens tube is fixed in place by inserting
the flange G into the ring B when the parts A and B are in the position shewn in
the elevation. The notches E coincide with the studs D and allow the flange to
pass through the ring. The lens tube with its flange G is then turned partly
D

page_text: round until the stop K comes against one of the studs D; then by turning the ring R
the flange G is nipped between the parts A and B.
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 appliance substantially as herein described consisting of parts A and B and
flange G, such parts being so arranged that the flange G can pass through the
ring B, when studs and notches with which the parts are furnished coincide, and
can then be locked between the parts A and B by turning the flange partly round
and screwing in the ring B.
