PROVISIONAL SPECIFICATION.
Improvements in Adjustable Seats or Stools for Music and other
purposes.
We JOHN WILLIAM DEANS of Alura Terrace Selby Engineer and ARTHUR MOSS
FOSTER of Park House Selby Manufacturer both in the County of Yorkshire do
hereby declare the nature of this invention to be as follows:-
--
This invention relates to improvements in stools or seats (also known as ottoman
stools) for use when playing the piano or organ etcetera or for other purposes which
seats or stools are capable of adjustment that is the height thereof can be regulated by
raising or lowering according to requirements.
For this purpose we construct such stool or seat according to our present improve-
ments as follows:-
Upon four legs or other suitable supports or body is formed or mounted at the top
part thereof an open framework and at each of the four corners a rack is vertically
mounted firmly secured to such framework.
The seat proper consists of a framework (or kind of cover consisting of four sides and a
top) the four sides of which are made just large enough to enclose the aforesaid top
part of the supporting body and carries on the underside of the top the adjusting
mechanism while on its top side or outside it is upholstered and ornamented or
otherwise as desired.
The raising and lowering mechanism is as follows.
To the underside of the seat or top part of the stool two pairs of brackets are
attached and each pair at its lower end carries a horizontal transverse axle on the outer
ends of which are mounted toothed wheels or pinions (that is four pinions altogether)
which latter correspond with and gear into the aforesaid four racks fixed to the
legs or supports.
These two axles carrying the said four toothed wheels may be actuated in any
convenient manner and for this purpose we find it advantageous to mount about the
middle of each axle a toothed wheel which again are revolved by right and left handed
worms on a third horizontal axle at right angles to the two axles carrying the afore-
said toothed wheels and a supporting bracket for this third axle may be arranged if
desired between the said two worms.
On the outer ends of this third axle (which extend beyond the sides of the seat or
not as desired) are arranged a knob or other suitable handle with which to revolve
said axle and thereby adjust the height of the stool.
The brackets in which the transverse axles have their bearings may be cast separately.
or together as desired and all the several parts being of a simple and inexpensive
character we thus effect considerable economy while producing an adjustable music
or other stool or seat which is readily worked and not liable to easily get out
of order.
If desired the adjustment may be effected with a greater or less number of
racks and pinions than as before described for instance with two racks only instead
of four.

JUDIT LELM DI MULTIVATION
Improvements in Adjustable Seats or Stools for Music and other
purposes.
We JOHN WILLIAM DEANS of Alma Terrace Selby Engineer and ARTHUR MOSS
FOSTER of Park House Selby Manufacturer both in the County of Yorkshire do
hereby declare the nature of this invention and in what manner the sanie is
'to be performed to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in stools or seats (also known as ottoman
stools) for use when playing the piano or organ etcetera or for other purposes--which
seats or stools are capable of adjustment that is the height thereof can be regulated
by raising or lowering according to requirements.
'
For this purpose we construct such stool or seat according to our present
improvements as follows reference being made to the accompanying sheet of drawings
in which-
'
Fig. 1 is a side elevation partly in section of our said improved stool.
Fig. 2 is a cross sectional elevation on line 1-1 Fig. 3.
Fig. 3 is a plan of the stool or seat on line 2-2 Figs. 2 and 4 the cushion part or
covering being removed to shew the adjusting mechanism and
Fig. 4 is a sectional side elevation on the line 3-3 Fig. 3 looking in the direction
of the arrow x.
Similar letters of reference indicate corresponding parts throughout.
Upon four (or more) legs a or other suitable supports or body is formed or
mounted at the top part thereof an open framework 6 and at each of the four
corners thereof a rack c is vertically mounted firmly secured to such framework b.
The seat proper consists of a framework (or kind of cover consisting of four
sides and a top) the four sides d of which are made just large enough to enclose
the aforesaid top part 6 of the supporting body and carries on the underside of
the top e the adjusting mechanism while on its top side or outside it (the top e) is
upholstered and ornamented or otherwise as desired.
The raising and lowering mechanism is as follows.
To the underside of the seat or top part e of the stool two pairs of brackets ġ, g
are attached and each pair at its lower end carries a horizontal transverse axle
on the outer ends of which are mounted toothed wheels or pinions i (that is four
pinions i altogether) which latter correspond with and gear into the aforesaid four
racks C, fixed to the legs or supports a-b.
These two axles h carrying the said four toothed wheels i may be actuated in any
convenient manner and for this purpose we find it advantageous to mount about
the middle of each axle h a toothed wheel m which again are revolved by right and
left-handed worms o on a third horizontal axle n at right angles to the two axles h h
carrying the aforesaid toothed wheel i and supporting brackets p for this third
axle n may be arranged if desired between the said two worms o.
On the outer ends of this third axle ni (which extend beyond the sides of the seat
or not as desired) are arranged a knob or other suitable handle such ass with which
to revolve said axle and thereby adjust the height of the stool as will readily
be seen.
The brackets g in which the transverse axles h have their bearings may be cast
separately or together as desired and all the several parts being of a simple and
inexpensive character we thus effect considerable economy while producing an
adjustable music or other stool or seat which is readily worked and not liable to easily
get out of order.
If desired the adjustment may be effected with a greater or less number of racks
and pinions than as before described for instance with two racks only instead of

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
1. In an adjustable music stool or seat the combination with a supporting frame
and legs a and b of racks c, c thereon and pinions i the latter being attached and
working in the adjustable top part of the stool or seat substantially as and for the
purposes herein before described and illustrated in the drawings hereunto annexed.
2. In an adjustable music stool or seat we claim the movable top part thereof having
pinions mounted thereon actuated from the outside by suitable knobs or handles in
combination with racks mounted and secured on the supporting frame and legs
substantially as and for the purposes herein before set forth.
