Improvements in Fittings for Cameras.
We, JOSEPH ARTHUR WILBY and WILLIAM LECK TATTERSALL, trading as
Tattersall and Wilby, of Thornton Grove Works, Armley, in the City of Leeds,
Photographic Apparatus Manufacturers, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to so construct our fittings that the back of the
camera is held rigid in any position upon the base-board.
We employ the ordinary elbow side fittings, but they are each provided with
a V extension which fits into a V groove in the base-plate, or (rice versa) tho
groove may be upon the elbow and the extension on the base-plate.
To the elbow side fittings are hinged the ordinary side struts.
A rod or bolt, threaded at one or both ends, passes across from one elbow
to the other and is provided with suitable nut or nuts with milled head or
heads.
By this means the back can be slid along the base-plate and rigidly fixed in
any position by the bolt or rod and its nut or nuts.

We, JOSEPH ARTHUR WILBY and WILLIAM LECK TATTERSALL, trading as
Tattersall and Wilby, of Thornton Grove Works, Armley, in the City of Leeds,
Photographic Apparatus Manufacturers, 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 our invention is to construct camera fittings so that the body of
the camera may be held rigid in any required position upon the base-board.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of camera with our improved fittings applied.
Fig. 2 is a partial end elevation (enlarged), showing our fittings applied for
adjusting the back of the camera.

page_text: Fig. 3 is a partial end elevation (enlarged) of a modified form of the adjustment
shown in Fig. 2.
Fig. 4 is an enlarged cross-section at a a (Fig. 1), showing our fittings applied
for adjusting the front of the camera.
In carrying out our invention we employ the ordinary elbow side fittings A A, {
but they are each provided with a V-shaped extension B which fits into a corre-
sponding V-shaped groove C in the outer side of the base-board D; or (vice versa)
the groove may be upon the elbow A and the extension on the base-board D.
To the elbow side fittings A A are hinged the ordinary side struts E E. A rod
or belt F, threaded at one or both ends, passes across from one elbow A to the 1
other, and is provided with suitable milled nuts G G. By this means the back H
of the camera may be slid along the base-board D and rigidly fixed in
any desired
position by the bolt or rod F and its nuts G G.
In lieu of the elbows A A being adjusted on one rod or bolt F (as shown
in Figs. 1 and 2) they may if preferred have an independent adjustment at each 1
side of the camera (see Fig. 3). In this case a small plate K slides in a recess
behind the metal strip L in which the V-shaped groove C is formed, the said
plate being tightened against the strip L by the milled nut G.
Our improved fittings may be applied for adjusting the front M of the camera
(as shown in Fig. 4). In this case the V-shaped extensions B B are formed on the 2
side spring brackets N N, and the V-shaped grooves C C on the rack plates P P
which operate the focussing slide R, the adjustment being effected by means
of the winged nuts S S.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what 2
we claim is:
-
1. In photographic cameras, adjusting the body of the camera in any required
position on the base-board by means of sliding V-shaped projections or extensions
fixed or connected to the said body and fitting into corresponding V-shaped
grooves on the base-board, suitable means being provided for clamping the said 3
projections within the said grooves, substantially as shown and described.
2. In a photographic camera the combination of the base-board D having
V-shaped grooves C, the elbow side fittings A A having V-shaped exten-
sions B B, the bolt or rod F with adjusting nuts G G (or equivalent device),
and the side struts E E supporting the back H of the camera, the whole arranged 3
and operated substantially as shown and described.
