LOUIS CARSTEN NIEBOUR, of Clarence Street, Kingston on Thames Surrey,
Dealer in Musical Instruments, 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 an Improvement in the mode of raising and lowering
the seats of Music Stools; Chairs and the like. For this purpose I employ two,
three, or more acting screws, each having a nut inserted in the legs or supports of
the stool or chair. On the top of each screw is fixed a small cog wheel, the tops
of screws being kept in position by a plate of iron or other metal. Secured by
screws or otherwise to the under part of the seat is a large cog wheel being held in
position by a bolt which passes through the before mentioned plate, and is screwed
into the centre of the large cog wheel-thereby securing the top of the Stool to
the legs or supports. On the seat being turned the large large cog wheel acts on
the two, three or more smaller cog wheels, simultaneously, rapidly raising or
lowering, and securing a perfectly steady seat.
Instead of the large cog-wheel may
be used a cog-rim fixed to the under part of the seat, and outside the two, three, or
more small cog. wheels..
