Year: 1880

page_text: LETTERS PATENT to Philip Middleton Justice, of 14, Southampton Buildings,
in the County of Middlesex, Patent Agent, for an Invention of "IMPROVEMENTS
IN COMBINED ADJUSTABLE SEATS AND SCHOOL DESKS." A communication
from abroad by Achille Eugène Jourdain Damman and André Cassard, both
of Brussels, in the Kingdom of Belgium.
PROVISIONAL SPECIFICATION left by the said Philip Middleton Justice at
the Office of the Commissioners of Patents on the 27th October 1880.
PHILIP MIDDLETON JUSTICE, of 14, Southampton Buildings, in the County of
Middlesex, Patent Agent. "IMPROVEMENTS IN COMBINED ADJUSTABLE SEATS AND
SCHOOL DESKS." A communication from abroad by Achille Eugène Jourdain
Damman and André Cassard, both of Brussels, in the Kingdom of Belgium.
This Invention relates to that class of seat and desk which may be adjusted to
different heights as may be best suited to the requirement of the pupil or person
by which the desk is to be occupied. The desk and scat may also be moved from
place to place as may be required. To obtain these desirable results a base or
platform is employed (supported upon suitable castors), from which rise three
hollow cast iron columns within which slide in a vertical manner a corresponding
number of iron rods. Upon the top of two of these rods are secured iron plates or
tables which are secured to and support the desk.
The supporting rods are provided with a series of holes adapted to receive stop
screws, which pass through the hollow columns. The third hollow column is in
the same manner provided with a sliding rod carrying its superimposed platform
upon which is secured the seat. This rod is also provided with holes for the
purpose of receiving a stop screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Philip Middleton Justice in the Great Seal Patent Office on the
25th April 1881.

number of iron rods. Upon the top of two of these rods are secured iron plates
or tables which are secured to and support the desk. The supporting rods are
provided with a series of holes adapted to receive stop screws, which pass through
the hollow columns. The third hollow column is in the same manner provided
with a sliding rod carrying its superimposed platform upon which is secured the
seat. This rod is also provided with holes for the purpose of receiving a stop
screw. To better and more fully describe the nature of the Invention, reference is
made to the annexed Drawing, in which
Figure 1 is a view in perspective of the improved combined seat and desk.
Figure 2 is a top view of Figure 3, showing one of the iron plates or tables to
which the desk is attached.
Figure 3 is a sectional view of one of the supporting legs of the desk.
Figure 4 is a sectional plan of Fig. 3.
Figure 5 is an enlarged view of a portion of Figure 3, showing the stop screw or
pin which holds the desk in position.
A is a wooden.base or platform fixed on a sole B, which is supported by the
three feet or castors C. To the platform A are secured the three hollow cast iron
columns E, E', F, in which slide the iron rods G, G¹, provided with suitably placed
holes through which the stop screws or pins O are passed from the outside of each
column so as to regulate the height of the desk M or seat. A support or socket H¹
is cast on the underside of the iron plate or table H, while in and to this socket is
secured the sliding rod G. In order to render the sent more comfortable, a wooden
back may be secured to the iron supporting rod D, which in its turn is secured to
the iron plate of the seat. Said plate and seat, after being secured to the rod G'
by means of the socket H¹, will be adjustable as to height by the stop screw and
holes in the column F. The height of the desk and seat can thus be varied (and
maintained by the three stop screws O in the cast iron columns) to adapt it to the
height required by the pupil or person.
Having thus described the nature of the Invention of my foreign correspondents,
what I claim and desire to secure by Letters Patent is,-
The improved combined adjustable seat and desk constructed substantially as
herein before described.
In witness whereof, I, the said Philip Middleton Justice, have hereunto set
my hand and seal, this Twenty fifth day of April, in the year of our
Lord 1881
Signed and sealed in the
presence of
