JOHN BROWN of Edenderry House Shaws Bridge Belfast, Ireland Gentleman do
hereby declare the nature of this invention to be follows:-
as
A sphere of wood or other suitable material fixed to the bottom of the camera has
fitted on it three cupped or hollowed metal pieces, held against it, with moderate
pressure by springs, rubber bands or both combined. Each cup has two pins pointing
inwards on which the camera legs fit in the usual way one side of the divided upper
part of each leg fitting on the pin of one cup and the other side of the leg on that of
the neighbouring cup. In two of the legs the divided upper parts are held together
by catches or hooks.so as to keep the cups on which they fit from separating
beyond a certain distance-or this office may be performed by the springs above
mentioned.
The divided upper part of the third leg has a hook with tightening screw or else an
excentrically slotted look or other contrivance for the purpose of drawing the two
parts and the cups on which they fit together and thus binding the whole rigidly
together and fixing the camera firmly in whatever direction it has been pointed.

page_text: An Improved Adjustable Photographic Camera Stand.
JOHN BROWN of Edenderry House, Shaws Bridge, Belfast, Ireland, Gentleman, do
hereby declare the nature of my invention for AN IMPROVED ADJUSTABLE PHOTOGRAPHIC
CAMERA STAND and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
I employ a sphere of wood or other suitable material capable of being fixed or
attached to the bottom of the camera, and having fitted on it three cupped or
hollowed metal pieces, held against it with moderate pressure by springs, rubber
bands, or both combined. Each cup has two pins pointing inwards on which the
camera legs fit in the usual way, one side of the divided upper part of each leg by
preference fitting on the pin of one cup and the other side of the leg on that of the
neighbouring cup-or the two pins to which the respective legs are connected may
be on the same cup. In two of the legs the divided upper parts are held together by
catches or hooks so as to keep the cups on which they fit from separating beyond
a certain distance; or this office may be performed by the springs above mentioned.
Between the divided upper parts of the third leg or on them I employ a hook with
tightening screw or else an excentric slotted hook or other contrivance for the
purpose of drawing the two parts, or the cups on which they fit, together and thus
binding the whole rigidly together and fixing the camera firmly in whatever direction
it has been pointed.
In the annexed drawings Fig. 1 is a perspective view of one form of my invention
where A is a sphere of wood or other suitable material with a projection B on which
may be fixed a photographic camera, or other required apparatus, by means of the
screw C fixed in B or by a loose serew passing up through a hole in B or by other
suitable means.
DDD are three metal cups fitting on the surface of the ball A and held in
place by a spring E and a ring or spring F or either of them alone.
Each cup carries two projections, (one of which is shown at G) with.pins on which
the legs of the ordinary tripod stand fit in the usual way as above referred to.
Two of the legs are held in place by the usual catches as at HH; the third is
provided with a hook or catch K. so formed that when in the position shown the ball A
may be moved with moderate friction inside the cups D D D in order to point the
camera or other apparatus in the desired direction but when the hook K is pressed
down over the screw S¹ it draws the screws S and S¹ closer together and so clamps
the ball firmly in the desired. position.
Fig. 2 is an elevation of the hook K showing the form preferred and the slot and
clamping bolt for taking up wear.
Fig. 3 is another form of hook K, being a combination of hook and excentric lever
where the clamping action is performed by depressing the lever L so as to bring its
excentric part M against the projection N thus forcing the screw S nearer S¹. It
may also be provided with a slot and clamping bolt as in fig. 2.

page_text: I may also use for the purpose of the hook K, a hook or connexion provided with a
tightening screw by means of which it may be shortened or lengthened as required-
or other suitable contrivance.
Fig. is a perspective view of another modification of my apparatus in which the
description given for the various parts in Fig. 1 applies except as regards the
clamping action.
In this form the lower parts of the cups are made to pass through the ring F
which ring is provided with an excentric lever O. P. With this lever in the position
shown the ball A may be moved round inside the cups, but on depressing the end o
the excentric part 1 is forced against the lower part of the cup D and presses it
onwards, thus binding the three cups tightly on the ball A.
(With this form the legs of the stand may be pressed outwards by the pieces HH
shown in Fig. 1 or they and the pins on which they fit may be similarly arranged to
fig. 1.)
Fig. 5 shows another way of clamping the lower parts of the three cups by means
of a milled nut working on a screw cut on their tapering ends.
Fig. 6 is a sectional plan of the lower parts of the cups when another form of
clamping arrangement is used. Here the ends of the cups D D D are shown apart
hut may be pressed inwards on the ball by turning the hand nut R through one sixth
of a circle.
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-
1. The combination of the spherical ball, with a projecting piece or pieces for the
purpose of attaching the camera or other apparatus, and the sectional cups or sockets,
attachable to the legs and capable of being contracted to clasp the ball as shown and
described.
