COMPLETE SPECIFICATION.
Improvements in Music and other Stools.
I, JOSEPH FREDERICK JOHNSON, late of No. 17 Park End Road, in the City and
County of Gloucester, now of Zephyr House, Shobrooke, Crediton, in the County
of Devon, Furniture Salesman, 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:-
My invention relates to improvements in music and other stools and has for its
object the construction of the means of raising and lowering the stool to any height
to suit the convenience of any individual.
In order that my invention may be clearly rendered, reference may be had to the
accompanying sheet of drawing which is a perspective view of the improved stool
Letters of reference are used to indicate the various parts in the view.
In constructing a stool according to my invention, I employ an interior square
frame a, sliding inside an exterior one b, the interior frame to be raised and lowered
by means of the four wooden slips, c. c. c. c. at front and back. These four slips are

page_text: loosely pivoted together to enable the two upper oues of each series to be released
from the ratchets when raising or lowering the inner frame. The aforesaid upper
slips are so constructed to drop automatically into the ratchets d in legs of exterior
frame; a spring e being affixed above the top of each series of slips to force same
into the ratchets. The two lower slips of each series to be pivoted to the bottom
rails. A projecting piece is employed at front and back for the purpose of
allowing the hands to draw the slips out of the ratchets when required to lower the
inner frame. Said piece g may be either of wood or shaped in metal.
The action is as follows: In increasing the height of the stool, the slips c. c.
move out of their respective ratchets by the act of drawing up the inner frame;
the springs forcing them into the ratchets at the required height. In decreasing
the height, the slips are drawn up clear of the ratchets by the hands being placed
under the pieces g; the inner frame is then lowered to the required height, and on
removing the hands the slips are released and forced into their respective ratchets
by the action of the springs e.
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 1
claim is
"First. In music and other stools the combination of parts whereby the height
may be adjusted instantly, substantially as herein described and shown.
Second. In music and other stools the combination of an inner frame with an
outer one, the inner frame being connected with a series of movable slips at front
and back of stool, substantially as herein described with reference to the appended
sheet of drawing.
