PROVISIONAL SPECIFICATION.
Improved Means for Raising and Lowering School and other Seats
and Tables and the like.
We HARRY ARNOLD BARLOw of Maple Road, Winton, near Bournemouth,
Coach Builder and Carpenter and EDWIN WILLIAM BUDDEN of Woodend Road,
Winton near Bournemouth, Smith, do hereby declare the nature of this invention
to be as follows:-
This invention relates to means for raising and lowering school and other seats
and tables and the like.
According to this invention we fix a rod under the seat lengthwise such rod
being provided with arms at its ends and to the upper ends of the said arms we fix
rollers capable of revolving and to the lower ends of each of said arms we fix a
toothed quadrant, so that the teeth of each pair of quadrants shall engage.
The aforesaid rod is squared at ends for a spauner, so that the seat, or table and
the like may be raised and lowered at once as may be desired.
And in order that our said invention may be better understood we will describe
the same with reference to the accompanying sheet of drawing in which :-
Fig. 1 shews elevation of our invention as applied to a seat.
Fig. 2 end view of same.

pulled off, n is a pin fastened to chain o. The pin n is to pass into one or other of
the holes pp if it is desired to hold the seat up but not to its full extent.
The action is as follows:-
When it is desired to raise the seat into the position shewn at Fig. 2 the handles h
are turned by which the quadrants ff are rotated and the arms ii are brought
from the position shewn at Fig. 3 to that shewn at Fig. 2 in the direction of
the arrows flight i.e. in the raised position and in order to lower the seat again the
handle would be turned in an opposite direction and the arms would follow the
arrows (Fig. 2) and finally rest as shewn dotted at Fig. 2 until the top a of seat rests
on the frame h.
Should the seat be required to be held at an intermediate height, then we insert
the pius n in one or other of the holes
and p¹.
Various articles may be raised by the above means such as tables desks stools and
the like.

We HARRY ARNOLD BARLOW of Maple Road, Winton, near Bournemouth,
Coach Builder and Carpenter, and EDWIN WILLIAM BUDDEN of Woodend Road,
Winton near Bournemouth, Smith, 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 means for raising and lowering school and other seats
and tables and the like.
According to this invention we fix a rod under the seat lengthwise such rod being
provided with arms at its ends and to the upper ends of the said arms we fix
rollers capable of revolving and to the lower ends of each of said arms we fix a
toothed quadrant so that the teeth of each pair of quadrants shall engage.
The aforesaid rod is squared at ends for a spanner, so that the seat, or table and
the like may be raised and lowered at once as may be required.
And in order that our said invention may be better understood we will describe
the same with reference to the drawings accompanying the Provisional Specification
in which,
Fig. 1 shews elevation of our invention as applied to a seat.
Fig. 2 end view of same.
Fig. 3 detail (shewing seat raised about half way) hereafter referred to.
The same letters denote the same parts in all views.

frames for carrying the raising and lowering mechanism (shewn enlarged at Fig. 3)
ee shew supports for the frames d d. ff are two toothed quadrants keyed on
spindles g g in the frames d d the spindle g¹ running the whole length of seat, and
said spindle is provided with handles hh. ii are arms fixed rigidly to the
quadrants and carrying at their upper ends rollers kk, ll are pieces of metal
having flanges for the rollers & to butt against when the seat is raised to its full
extent as at Figs. 1 and 2. mm shew hook pieces taking under the frames d d
to prevent the top of scat from being pulled off. n is a pin fastened to chain o.
The pin n is to pass into one or other of the holes p p if it is desired to hold the
seat up but not to its full extent.
The action is as follows:-
When it is desired to raise the seat into the position shewn at Fig. 2 the handles h
are turned by which the quadrants ff are rotated, and the arms ii are brought from
the position shewn at Fig. 3 to that shewn at Fig. 2 in the direction of the arrows
flight i.e. in the raised position; and in order to lower the seat again, the handle h
would be turned in an opposite direction, and the arms would follow the arrows
(Fig. 2) and finally rest as shewn dotted at Fig. 2 until the top a of the seat rested
on the frame h.
Should the seat be required to be held at an intermediate height, then the pins n n
are inserted in one or other of the holes p p².
Various articles may be raised by the above means such as tables, desks, stools,
and the like.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
(1) The means for raising and lowering school and other seats and tables and the
like, consisting of the rods bb, tubes c, frames d d, quadrants ƒƒ, spindles g g¹,
