PROVISIONAL SPECIFICATION.
Improvements in the Construction of Adjustable Tables and
Supports suitable for Photographic Stands, Engraving Tables,
and other uses where Variations of Height and Angle are
required.
I HENRY DANIEL Buttrum of the Parish of St. Giles Stony Stratford in the
County of Bucks Cabinet Maker and Photographer do hereby declare the nature
of this invention to be as follows:-
To enable the photographer to photograph objects from the floor level to the full
height of the stand or in the case of engraving tables to enable the operator to
rapidly change the height or the angle of the table and this I effect by improve-
ments in the construction of the stand of the table and the bracketed support of
the table, the stand consists of an upright tube of iron or other suitable material
on the top of which a casting of metal is fitted the base may consist of a casting of
metal or a holder of wood and is fitted with suitable castors or rollers to enable the
stand to be moved to the position required the top and base are connected by rods
of iron or other metal and screwed at either end and made fast through suitable
holes with lock nuts, the rods are so placed as to form with the upright tube a
form of tripod the rods are made firm by a stretcher of metal or wood or other
material which grips the rods, the upright tube is turned true or formed of rolled
steel, the top holder has a sheathed pulley in which runs a weighted cord, or chain,
or spiral spring, as a counter weight or motion to the support of the table which is
slideing and adjustable, consisting of a suitably formed slidcing bracket of metal or
other suitable material, one end of which is bored out to fit the upright with a
little play so as to grip the upright the instant the camera is placed upon the
table the other end of the bracket extends out on one side to the distance required
and is fastened to wood work of the usual constructions to move the table it is
nesscessary to take the weight off the upright and it can then be instantly raised
or lowered and placed at any desired position or angle, it is unnesscessary to move
the camera after being fixed to the table as the bracketed table can be swung
round the upright tube and can be instantly brought to any point and firmly griped
by a cam or set screw or any other suitable device.

Cabinet Maker and Photographer, Stony Stratford, Bucks.
COMPLETE SPECIFICATION.
Improvements in the Construction of Adjustable Tables and
Supports suitable for Photographic Stands, Engraving Tables,
and other uses where Variations of Height and Angle are
required.
HENRY DANIEL BUTTRUM Cabinet Maker and Photographer of Stony
Stratford in the County of Bucks 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 this invention is to enable the photographer to photograph objects
from the floor level to the full height of the stand or in the case of engraving

page_text: tables or drilling machines to enable the operator to rapidly change the height or
the angle of the table and this I effect by improvements in the construction of the
stand of the table-and in the bracketed support of the table. The stand consists of
an upright tube of iron or other suitable material on the top of which a suitable
casting of metal is fitted. The base may consist of a casting of metal or a holder
of wood and is fitted with suitable castors or rollers to enable the stand to be
moved to the position required, the top and base are connected by rods of iron or
other metal or metal tubes and screwed at either ends and made fast through
suitable holes with lock nuts the rods are so placed as to form with the upright
tube a form of tripod the rods are made firm by a stretcher of metal or wood or
other material which grips the rods.
The upright tube is turned true or formed of rolled steel or other suitable
material the top has a sheathed pulley in which runs a weighted cord or chain or
spiral spring or other suitable device to act as a counter weight or motion to the
bracketed support of the table which is sliding and adjustable consisting of a
suitably formed sliding bracket of metal or wood or other material one end of
which is bored out to fit the upright tube with little play so as to grip the upright
the instant the camera or other object is placed upon the table, the other end of
the bracket extends out to the distance required and is fastened to woodwork or
other material in the usual manner or as shown in section drawing Figure 4 at (r)
with ordinary wood screws.
In some cases I can use a rule joint acting on a cam to secure the position of
the bracket as shown in Figure 4 at (g).
To move the table it is only nescessary to take the weight off the upright by
raising by the hand the extended part of the bracketed table it can then be
instantly raised or lowered and placed at any desired position or angle the hand
when taken away causes the table to be instantly fixed by its weight.
It is unnescessary to move the camera after being fixed to the table as the
bracketed table can be swung round the upright tube and can be brought
to any point and firmly griped by a cam or set screw or any other suitable
device.
In order that my invention may be fully understood I have shown in the drawings
hereunto annexed, a table stand constructed as above described.

(a) sheathed pulley attached to and forming part of top holder (c) (b) stay rods.
(d) cord or chain attached to the bracketed table (e) (9), and passing through a
hole in the top holder (c) and over the sheathed pulley (a) and is attached in the
usual manner to the weight (h) (f) set screw to the riseing and falling table (e)

at which the bottom part of table is fixed (7) rule joint forming cam for some
machines where other angles are required.
Having now particularly described and assertained the nature of my said inven-
tion and in what manner the same is to be performed what I claim is―
First. A sliding self adjusting bracketed support attached to and forming a table
of wood or metal sliding on an upright tube which can be placed at any angle or
height and held in position by the leverage of the extended portion of the support
or table as shown in the enlarged section drawing Fig. 4.
Second. The combination of a hollow tube with a sliding adjustable bracketed

page_text: table with circular movement and counterweight as described and illustrated in
drawings and in the foregoing Specification.
Third. The single fixed upright tube with or without its stay rods with its holders
top and bottom and the top holder with its sheathed pulley in combination with the
5 adjustable bracketed table as described and illustrated in the foregoing Specification
and drawings.
