IMPROVEMENTS IN PHOTOGRAPHIC CAMERA STANDS FOR USE OUT OF DOORS ON LAND OR AT SEA
Year: 1884

page_text: PROVISIONAL SPECIFICATION,
I, JAMES THOMSON, of 21 High Park Street, Liverpool, in the county of
Lancaster, Photographer, do hereby declare the nature of my invention for
IMPROVEMENTS IN PHOTOGRAPHIC CAMERA STANDS FOR USE OUT OF DOORS ON
LAND OR AT SEA, to be as follows:-
My Invention relates to extra or additional supports to be fixed or attached to
the legs of any tripod stand by means of suitable screws. These supports may be
made of brass, wood or other suitable material, and when attached and in proper
position extend up to the bottom of the camera and can be attached or pressed
against the same. When so attached or pressed they render the Camera perfectly
rigid in case of wind or other disturbing element. The supports are preferably four
in number and each of them can be elevated or lowered to the position required by
the adjustment of the camera, by means of a longitudinal slot in the lower part of
the support through which slot the screw is attached to the leg of the stand by a
nut or other means. My invention also relates to the adaptation of a double swing
(similar to that of a compass) in the top of the tripod stand. On the top of this
swinging apparatus the Camera is fastened by suitable means. From the swing a
rod or brass tube, (similar to a pendulum) with a weight attached to its lower end
extends downwards thus balancing or maintaining the camera in a horizontal or
level position when being used at sea (or elsewhere under similar conditions) for
taking instantaneous photographs.

Lancaster, do bereby declare the nature of the said invention for IMPROVEMENTS

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
My invention relates to extra or additional supports to be fixed or attached.to
the legs of any tripod stand by means of suitable screws.
These supports may be
made of brass, wood or other suitable material and when attached and in proper
position extend up to the bottom of the camera and can be attached to or pressed
against the same. When so attached or pressed they render the camera perfectly
rigid in case of wind or other disturbing element. The supports are preferably four
in number and each of them can be elevated or lowered to the position required by
the adjustment of the camera by means of a longitudinal slot in the lower part of
the support through which slot the screw is attached to the leg of the stand by a
nut or other means. My invention also relates to the adaptation of a double swing
(similar to that of a compass) in the top of a tripod stand. On the top of this
swinging apparatus the camera is fastened by suitable means.
From the swing a
rod or brass tube (similar to a pendulum) with a weight attached to its lower end
extends downwards thus balancing or maintaining the camera in a horizontal
or level position when being used at sea (or elsewhere under similar conditions)
for taking instantaneous photographs..
DESCRIPTION OF THE DRAWINGS.
Figs 1 and
are side elevations at right angles to each other of a camera and
stand provided with additional adjustable supports under my invention. Fig 3 is
a front view of one of the supports and figs 4 and 5 at right angles showing the
means of securing the supports to the camera stand. a tripod stand of usual
construction. b camera, c additional supports made with slots d and attached
to the legs of the camera stand a by means of the binding screws e which pass
through the slots d and take into the nut plates f secured to the legs of the stand.
The upper ends of the supports c are adjusted to press against the bottom of the
camera before being secured in position or they may be hinged or otherwise secured
to the said camera.
Fig 6 is a perspective view of a camera stand and camera fitted with my
improved swinging apparatus for balancing and maintaining the camera horizontal
or level when being used at sea or elsewhere under similar conditions for taking
instantaneous photographs. Within the cap of the stand a I suspend on pivots g
the ring hand hang from the ring the rod and weight i by pivots j at right
angles to the pivots g. To the upper end of the rod i the platform j on which the
camera rests is connected by the knuckle joint and binding screw k.
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
First. The combination with camera stands and camera's of adjustable additional
sunports.

page_text: Second. The combination with camera's of a pendulum or swinging weight
suspended in cross bearings in the stand substantially as setforth.
Third. The combination with camera's and stands of additional adjustable
supports and pendulum or swinging weights.
