Self Adjusting Tripod Head.
WILLIAM GOODE Thorn Lodge Mulgrave Road Sutton Surrey Gentleman do
hereby declare the nature of this invention to be as follows:-
With this invention a dead level platform is obtained with one movement. Let
the tripod be placed in any level or uneven surface, by merely tightening a screw
the platform or head is dead level all ways. It is constructed with a ball and
socket joint, to the ball a pendulum with rigid wire, of any length or weight is fixed
to suit requirement. The top socket is screwed down permanently allowing sufficient
play for the ball to move. A screw is placed at the side to fix the ball. There is
a screw on the ball above the socket to take a table or platform, for hand or other
cameras. It can also be adapted to any or most of the tripods in present use, by a
flange fixed to the head. This invention is equally adapted for the theodolite.
dumpy level &c. or any instrument requiring accurate level adjustment.

COMPLETE SPECIFICATION.
Self Adjusting Tripod Head.
I, WILLIAM GOODE, of Thorn Lodge, Mulgrave Road, Sutton, in the County of
Surrey, Gentleman, 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 a self-adjusting tripod head, and will be best understood
by reference to the accompanying drawings in which
Fig. 1 is a perspective view of the upper part of a tripod stand constructed
according to this invention, and
Fig. 2 is a perspective view of the underside of the table for attachment
thereto.
Fig. 3 is a vertical section through the table and ball and socket joint.
Like letters indicate like parts throughout the drawings.
A are the legs all of which are jointed to the socket piece B the upper part of
which is hollowed out as shown in Figure 3 for receiving the ball C and is externally
screw-threaded for receiving the cap or collar D which when screwed in position
holds the ball C in the seat provided in B.
The cap or collar D is formed with one or more screw-threaded holes each for
receiving a screw E provided preferably with a milled head E' and adapted by
being screwed against the ball C to hold said ball and its attachments rigidly in
the position which it has assumed. At the upper part of the ball C is provided the
screwed projection C' on to which may be screwed a nut F secured at the underside
of the table F¹.
Secured to the lower part of the ball C and projecting down through the central
opening of the cup piece B is the rod C on which the tube G' of the pendulum G
fits and is adjustable telescopically.
When it is desired to use the before described apparatus the legs A are opened
out to stand upon the ground in the usual manner and the screws E' are released
from the ball C when by the pendulum G G assuming its normal or vertical
position the table F' will be brought to its horizontal position one or both of the

page_text: screws E¹ are then tightened so as to clamp the table and pendulum in the position
thus assumed.
The before described apparatus may be used for supporting photographic
camera, theodolite, dumpy level or other instruments requiring accurate level
adjustment.
The provision of the tube G¹ on the pendulum for sliding upon rod C³ of the ball
is a convenient arrangement for enabling the parts to be taken asunder should it be
required to remove the ball C from the socket or seat B so as to enable the parts to
be packed into as small compass as possible.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,―
1. In apparatus such as described the combination with a ball and socket joint
such as CBD of a pendulum secured to or formed in part with the ball thereof
substantially as described and illustrated in the accompanying drawings.
2. In apparatus such as described the combination with a ball and socket joint
such as CBD and pendulum such as C G G¹ of adjusting or binding screws such
as E substantially as described and illustrated in the accompanying drawings.
3. The combination and arrangement of parts constituting the self-adjusting
tripod head substantially as described and illustrated in the accompanying
drawings.
