Improvements in or Connected with Photographic Cameras.
I JOSEPH LENDON BERRY of 43 Cardiff Street Aberdare in the county of
Glamorgan Photographer do hereby declare the nature of this invention to be as
follows:-
In the first place I construct a stock suitable for using from the shoulder, the same
being provided with a suitable block to which any Camera may be attached and also
provided with a holder to contain the ball of a pneumatic release such ball being
actuated by a Trigger forming part of the Gun, instead of by hand as hitherto thus
ensuring perfect steadyness when exposeing a plate, both hands being available for
holding the Gun.
Dated this 10th day of March 1888.

Improvements in or Connected with Photographic Cameras.
I JOSEPH LENDON BERRY of 43 Cardiff Street, Aberdare, in the county of
Glamorgan Photographer 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 :-
I construct a holder A in the form of a gun stock of any suitable wood, having a
block or head B, at the front end of the same, such block or head having a tablet of
wood C projecting from it towards the front sufficiently large to enable any ordinary
Camera to be attached thereto by its screw in the usual manner in which a camera is
fixed to its stand. I construct in the Block or head, a hole D to act as a receptacle for
the ball of any pneumatic shutter that may be used on any Camera, such hole being
perforated through the head from side to side. I also construct another hole E in the
rear end of the block or head into and intersecting the first mentioned hole, this
second hole being furnished with a piston F. such piston being for the purpose of
squeezing the air from the ball through the tube of any shutter that might be used.
The piston has a crosshead or T piece at its rear end which interlocks with a spring
catch G that is affixed to the upper surface of the stock or holder and is acted on by
a trigger H placed in a hole made perpendicularly through the neck of the stock or
holder, the lower end of such trigger may, or may not be covered with a trigger
guard M'as may be desired, the top of such trigger having a small hole made in it
perpendicularly for the purpose of carrying a bent wire 1 fixed in such a manner that
it may be turned forward over the T head of the piston when the T head is inter-
locked with the spring catch so as to prevent it from being discharged by accident as
the trigger cannot be pulled back until such bent wire is turned toward the rear end
of the stock or holder. The piston is pulled toward the ball receptacle D by the force
of two springs JJ which may be of rubber or spiral wire or otlier suitable substance
and are fastened at the front end of the block or head and may or may not be
permanently attached to the T head of the piston, such springs when placed on the
Thead serving to retain the ball in its receptacle as well as actuating the piston.
The stock or holder may. he made to fold in two or more parts thus makeing it more
portable and convenient for transport, such joints or foldings being furnished on one
side with a strong hinge K, and on the other with a similar hinged piece, screwed fast
at one end the other end having a slot in it for the passage of a turn button L
or similar contrivance for the secure fastening of the joints when being used.

page_text: Having now particularly described the various parts of my invention, and
in what manner the same is to be performed now declare that what I
claim is
The form of head of holder or stock with the manner of affixing any Camera to it,
with a receptacle for the ball of any pneumatic shutter in it, also the manner of
actuating the ball by means of a piston furnished with springs and a trigger opperated
in the manner of firing a gun instead of the ball bein squeezed by hand as
hitherto.
