PROVISIONAL SPECIFICATION.
Improvements in Supports for Photographic Cameras.
We, GEORGE MASON, of 180 Sauchiehall Street, Glasgow, in the County of
Lanark, North Britain, Apparatus Manufacturer, and ALEXANDER LAMONT
HENDERSON, of 277, Lewisham High Road, St. Johns, in the County of Kent,
Merchant, do hereby declare the nature of this invention to be as follows, that is
to say:
This invention relates to photographic-camera supports of the tripod or jointed-
leg class, and has for its object to provide improved adjustable mechanism for
fixing the legs rigidly in a required position so that they will not tend to spread or
otherwise move in a manner to alter the position of the camera.
The improved mechanism consists, in the case of a tripod stand, of three
steadying bars, with a clamping screw or screw box for fixing them together
centrally with the bars radiating from the centre to a greater or less extent as
required, in each case. The outer ends of the bars are fitted with parts for easy
attachment to the tripod legs. In the case of a common construction of tripod
stand in which each leg is locked upon the pins in the top frame on which the leg
is hinged, by a strut or turn-down pin which distends the sides of the leg, the ends
of the steadying bars may be arranged to engage with the said struts; or the struts
may be formed on the ends of the steadying bars. Any other convenient means
for connecting the steadying bars to the tripod legs may be used: The steadying
bars may be slotted longitudinally the clamping screw passing through the slots
and the bars being pinched between the head of the screw and a nut. Or the
steadying bars may be unslotted and be passed through slots in a small box, a
screw screwed into one end of the box serving to fix them.
.
When an operator is adjusting his camera- the clamping or fixing screw will be
loose, and the, adjusting bars free to move with the legs, and on obtaining the
adjustment he will simply liave to turn the screw until tight.

Improvements in Supports for Photographio Cameras.
We, GEORGE MASON, of 180 Sauchiehall Street Glasgow, in the County of
Lanark, North Britain, Apparatus Manufacturer, & ALEXANDER LAMONT
HENDERSON of 277 Lewisham High Road, St. Johns, in the County of Kent,
Merchant 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 :-
This invention relates to photographic camera supports of the tripod or jointed
leg class, & has for its object to provide improved adjustable mechanism for fixing
the legs rigidly in a required position so that they will not tend to spread or
otherwise move in a manner to alter the position of the camera.
The improved mechanism consists in the case of a tripod stand of three steadying
bars (a) with a clamping screw (6) or screw-box for fixing them together centrally
with the bars radiating from the centre to a greater or less extent as required in
each case (Figures 1 and 2). The outer ends of the bars are fitted with parts for
easy attachment to the tripod legs. In the case of a common construction of tripod

is hinged, by a strut or turn-down pin which distends the side of the leg. The
ends of the steadying bars may be arranged to engage with the said struts (Figure 3)
or the struts may be formed on the ends of the steadying bars. Any other con-
venient means for connecting the steadying bars to the tripod legs may be used
(Figures 4 & 5). The steadying bars may be slotted longitudinally the clamping
screw passing through the slots & the bars being pinched between the head of the
screw & a nut.. Or the steadying bars may be unslotted & be passed through
slots in a small box; a screw screwed into one end of the box serving to
fix them.
When an operator is adjusting his camera the clamping or fixing screw will be
loose, & the adjusting bars free to move with the legs & on obtaining the adjustment
he will simply have to turn the,screw until tight.
Figure 1 of the drawings filed herewith shows the invention adapted to an
ordinary tripod stand,
Figure 2 shows a complete support,
Figure 3 shows a steadying bar of the invention &
Figures 4 & 5 show a variety of modes of adapting the invention to varying
styles of tripod stands.
Having now particularly described & ascertained the nature of our said inven-
tion & in what manner the same is to be performed we declare that what we
claim is
...
The securing of perfect steadiness to the camera tripod stand when in use by
application of steadying bars (a) which can be made of metal wood or any other
suitable material. For easy attachment to any form of camera stand where struts
are not used a hook (c) is arranged with screw & loop-pin (d) for attaching to leg
or a ball at end of bar (E) for fitting into socket pin (d) for attaching to leg
of stand.
