PROVISIONAL SPECIFICATION.
A New or Improved Seat or Stool.
I, JAMES CLEGG, of 21 Briant Street, New Cross, in the County of Surrey,.
Carpenter, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved seat or stool for the use of performers
upon the organ, harmonium, and like key board instruments and for other
purposes where it is necessary to adjust the height of the seat to that of the
performer.
In carrying this invention into practical effect I attach to the underside of the
seat, which is preferably of rectangular form, two or more downwardly extending
arms or bars, each provided with a rack on one of its edges. To the base or foot
of the stool which is detached from the part described I secure two or more uprights
or standards (each divided vertically into two portions) grooved on their inner faces
so as to receive between them one of the said arms extending downwardly from the
seat. These standards or uprights support between them a horizontal shaft or
spindle provided with a hand-wheel by which it may be rotated. Secured to each
end of this spindle and located in a cavity in the inner side of the said standards is
a pinion engaging with one of the racks hereinbefore described.
It will be readily understood that the seat may be elevated or depressed by the
rotation of the said spindle. To retain the seat in any desired position a plug or
stop is provided on each standard which takes into the space between the teeth of
the rack. This plug or stop preferably consists of the point of a set screw working
within the said standard, but may be constructed in any other manner.
In order that the rack may be stopped and retained in such a position that the.
said plugs or stops may enter between the spaces and not strike against the teeth of
the racks, I provide one end of the horizontal shaft or axis with a.number of equi-
distant recesses arranged in a line around its periphery and pivot a pawl over the
same so that it may drop into the recesses by its own weight as they pass before it.
These recesses are so arranged that whenever the pawl rests within one of them one
space in each rack is opposite its stop or projection.

COMPLETE SPECIFICATION.
A New or Improved Seat or Stool.
I, JAMES CLEGG, of 21 Briant Street, New Cross, in the County of Surrey,
Carpenter, 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 a new or improved seat or stool for the use of performers
upon the organ, harmonium, and like key-board instruments and for other
purposes where it is necessary to adjust the height of the seat to that of the
performer.
In carrying this invention into practical effect I attach to the underside of the
seat, which is preferably of rectangular form, two or more downwardly extending
arms or bars, each provided with a rack on one of its edges. To the base or foot
of the stool which is detached from the part described I secure two or more uprights

faces so as to receive between them one of the said arms extending downwardly
from the seat. These standards or uprights support between them a horizontal
shaft or spindle provided with a hand wheel by which it may be rotated. Secured
to each end of this spindle and located in a cavity in the inner side of the said
standards is a pinion engaging with one of the racks hereinbefore described.
It will be readily understood that the seat may be elevated or depressed by the
rotation of the said spindle. To retain the seat in any desired position a plug or
stop is provided on each standard which takes into the space between the teeth of
the rack. This plug or stop preferably consists of the point of a set screw working
within the said standard, but may be constructed in any other manner.
In order that the rack may be stopped and retained in such a position that the
said plugs or stops may enter between the spaces and not strike against the teeth
of the racks, I provide one end of the horizontal shaft or axis with a number of
equidistant recesses arranged in a line around its periphery and pivot a pawl over
the same so that it may drop into the recesses by its own weight as they pass before
it. These recesses are so arranged that whenever the pawl rests within one of them
one space in each rack is opposite its stop or projection.
And in order that my invention may be more readily understood and carried into
practice I will now proceed to describe the same with reference to the
accompanying sheet of drawings of which
Fig. 1 is a back elevation and Fig. 2 an end elevation.
The seat a has secured to it two downwardly projecting arms each provided
with a rack on one of its edges. To the base d of the stool are secured two
vertically divided uprights e between the inner grooved faces of which the arms b
slide.
Revolving in bearings in the uprights e is a horizontal shaft provided with a
hand wheel and having secured to each end thereof a pinion / revolving in
cavities in the uprights e and gearing with the racks c.
It will thus be seen that the seat a may be raised or depressed on revolving the
shaft by the aid of the hand wheel
9.
The seat is retained in the position desired by means of set screws & the point of
each of which enters one of the spaces between the teeth of the racks, the seat
being caused always to rest in a position that this may be effected by the aid of
pawl pivoted to one of the uprights e and arranged to drop into recesses / formed
in the surface of the shaft f.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An adjustable stool constructed and operated substantially as described and
ascertained in the accompanying drawings.
