IMPROVEMENTS IN PHOTOGRAPHIC CAMERAS
Year: 1884

page_text: SAMUEL DUNSEITH MCKELLEN of Number eighteen Brown Street in the City of
Manchester do hereby declare the nature of my invention for IMPROVEMENTS IN
PHOTOGRAPHIC CAMERAS to be as follows:-
My invention relates to that part of the photographic camera which is usually
called the tail board or base board, and is intended to avoid the necessity of
carrying the loose piece to which the tripod legs have hitherto been attached when
I cut a
the camera was in use and which loose piece is called the tripod top.
circular opening out of the camera base board and I insert the tripod top therein.
This tripod top is made of wood metal or other convenient material and fits neatly
into the aforesaid opening where it is held by flanges which whilst holding the
tripod top firmly in the the base board allow the camera to turn in any direction
as on a turn table in order to bring the camera into the position required The
position being ascertained the flanges can be drawn towards each other by a set
screw or other mechanical arrangement so as to cause them to clip tightly on the
base board and thus fix the camera in its required position.
Dated this first day of January eighteen hundred and eighty four.

page_text: I SAMUEL DUNSEITH MCKELLEN of 18 Brown Street Manchester Watch
Manufacturer & Jeweller do hereby declare the nature of my invention for
IMPROVEMENTS IN PHOTOGRAPHIC CAMERAS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My invention is intended to dispense with the loose tripod head to which the
camera legs are usually attached when the camera has to erected for use. I make
a recess or aperture in the base board of the camera and in this I insert the tripod
head which I now call the turntable' This turntable is constructed so that when
required the legs may be connected with it by means of the usual pins or by
screwing or in any of the ways which are well known to the trade The turntable
may be held in its place by many methods but by preference I fix to its edge two
rings or flanges or work the flanges on it when it is being made. These flanges
project all round the turntable that they overlap a little way on the base board
one flange on each side of it, that is one flange above the wood work of the base
board and one flange below it, or the flange may be worked on or attached to the
upper and lower surfaces of the baseboard and the turntable would then be clipped
between the flanges in either case the turntable and base board would revolve
within and around each other respectively, being held in the same plane by the
flanges When the camera is erected and the proper position obtained it may be
held in that position by any convenient mechanical arrangement but I prefer to
use a set screw which draws the flanges together thus binding them on the base
board or on the turntable as the case may be.
In the accompanying drawings

3 shews the turntable in position in the baseboard which is partly in section.
4 is a plan of the turntable and baseboard.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is 1st In a photographic camera a recess or aperture (in base board) to
receive a turntable or tripod head substantially as hereinbefore described.
2d In a photographic camera a turntable or tripod head inserted and revolving
in said aperture or recess in camera base board substantially as hereinbefore
described.
