PROVISIONAL SPECIFICATION.
Improved Mode of Fixing a Photographio Camera to Stand.
HARRY LLOYD WRIGHT The Firs Loughton Clerk. I do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide a simple means of fixing a photographio
camera of any form to a stand of any form, & to do away with the ordinary holding
down screw. To carry out this improvement I have a frame (circular or otherwise)
with a boss in the centre, the level of the top face of boss to be below (say) the
level of the top face of frame. A hole is bored through the boss. An oblong block
having a dovetail shaped groove in the top from end, to ond, having a stem on its
underside is fitted into the hole i.e. the stem is fitted into the hole & the top of block
is to be say below the top face of frame. A small slide is fitted into the groove
in block, & is attached to the base of the camera, so that on sliding it in to tho
groove in block it fastens the camera to the block.
At the bottom of stem & on the underside of frame is fitted an eccentric, ending
inn handle, which turns on a pin driven through eccentric & stem, when the handle
is turned up horizontal the block is quite free to turn round, then by sliding the
small slide into the groove in block on turning the handle down the large part of
eccentric presses against the underside of frame and draws the block with camera
attached firmly down on to the top of frame, thereby 'fixing camera to frame.

COMPLETE SPECIFICATION.
Improved Mode of Fixing a Photographic Camera to Stand.
HARRY LLOYD WRIGHT The Firs Loughton Essex Clerk. I 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 object of this invention is to provide a simple means of attaching a camera
of any form, to a stand of any form & to do away with the ordinary holding down
BCrew.
The means I take to carry out this improvement are, to have a frame with a boss
in the centre, bored to take the stem of a block, the top surface of boss being sunk
below the surface of frame to such an extent that the top of block shall be below
the top surface of frame.
The top of block is grooved to take a small slide, which slide is fastened to the
base of camera.
To the end of stein of block & below boss is fitted an eccentric, so
that when the slide with camera attached is slipped into groove in block, by
revolving eccentric & bringing the largest part to bear against underside of boss, it
draws the block & camera attached down on to the frame thereby fixing it.
Now referring to accompanying drawing,
Fig. 1 is a plan view.
Fig. 2 is a sectional elevation.
Fig. 3 is a side elevation of the central fittings.
Fig. 4 is the same as Fig. 3 with the exception that the eccentric is horizontal
instead of vertical as in Fig. 3.
r
Fig. 5 is a plan & end elevation of slide that fits in groove in block.

page_text: rim of A by six strips, the top of boss being of an inch below top surface of A.
A hole is bored through boss in which fits a block B with a stem, the stem going
right through & projecting on underside of boss.
1n Fig. 2 we have a sectional elevation view of A & shewing end view of block B
& the shape of groove in top of B from one end.
To the bottom of stem of B is fitted an eccentric, C, ending in a handle which
turns on a pin D, driven through eccentric & end of B.
In Fig. 3 we have a side view of B & of C, showing the larger part of C,
marked, E, pressing against underside of boss of A & holding B down on to face of
boss, the handle of C being turned down.
In Fig. 4 we have a view similar to Fig. 3 with the exception that the handle
of C is turned up horizontal allowing the smaller part of eccentric, C marked, f, to
come opposite lower face of boss of A thereby allowing space for B to move up &
down in boss.
In Fig. 5. we have an end & top view of G, a slide that fits in groove in B, & in
Fig. 6 we have a side elevation view of G shewing it attached to base of camera.
Now by turning handle of C up, you can move B up a little & by sliding G with
camera attached into groove in B the camera becomes attached to B, but you are
able to turn camera round on face of A; when you get camera in the required
position by turning handle of C down, the larger part of C, marked, E, presses
against underside of boss drawing block B with camera attached, firmly down on
to frame A thereby fixing camera to A. the tripod legs or whatever other stand
may be suitable are fixed to A.
Having now particularly described the nature of my invention of improved mode
of fixing photographic camera to stand & in what manner the same is to be
performed, I claim
.
Firstly. A grooved block slide as a means of attaching camera to stand head
frame.
Secondly. The use of an eccentric or eccentric shaped fitting to lock camera to
frame, when slide is placed in block by drawing it down on to frame.
Thirdly. By means of a block & eccentric working together as already explained
to have provided a new means of attaching camera to stand.
