EMMANUEL BALL Professor of Music 112 Lichfield Street Walsall do hereby declare
the nature of this invention to be as follows:-
The two sides which are the chief support of the Music stool or seat may consist
of two strips of Wood, Metal, Metal & Wood combined or any other suitable
Material.
Each of these two strips are pivoted through, or at their centre so as to allow them
to open or close as desired. A cross bar may extend from pivot to pivot if desired,
by way of strengthening the centre of the stool. To support the sides or cross legs
of the stool at the top and bottom, four cross bars may be secured to them. The two
top cross bars may be made to work freely at their ends into the holes made in the
sides or cross legs to receive them, so as not to impede the movement of the screw
pin which works through them. These two top cross bars will each have a hole bored
through them across their centre. The hole in the back cross bar will be tapped so
that a screw pin may be screwed through it into the hole made in the other cross bar
to receive it. The screw pin will have a small wheel or handle at its outer end to
enable one to turn it readily. It will also have a set off or nut and pin arrangement.
at the other end by which means it will be permanently attached to the front cross
bar. It will be clearly seen if the screw pin is permanently fixed to the front cross
bar and works or screws freely through the tapped hole or socket of the back
cross bar, the moveable sides or cross legs of the stool may be opened or closed by it
at pleasure, which by so doing will raise or lower the seat of the stool as desired. The
seat of the stool will be supported and carried by two cross bars which are fixed by
means of Pins or Screws to either side of the top of the moveable cross legs or sides.
These two top cross bars to which the seat is fixed will each have a slot or groove cut
in, or through them at their one end. These grooved portion will work on a pivot or
pin fixed in either side of the stool, and so admit of the seat riding freely on the top
of the inoveable sides when the are opened or closed for the raising or lowering of
the stool. If desired, teeth may he made in the upper portion of the Slots of the
Slotted bars which carry the seat, and a pin fixed in either side of the stool for the
teeth of the slots to fit on. It would then only be necessary to lift and push or pull
the seat over these pins to raise or lower it. This would dispense with the screw pin
arrangement. If desired, the lifting of the slotted bars over the pins to raise or lower
the seat, might be done by means of one or more pins (having a hanale at one end
and a small cog wheel or lift on the other end) being fixed through the sides of the
stool. By turning the pins the tooth slotted bars may be lifted backwards or forwards
over the side pins and so raise or lower the seat. The cross legs or moveable parts of
the stool may be pivoted and made to move only from the centre of the stool, if
desired. The lower part or feet of the stool would in this case be always at a fixed
distance. The Music stool may have a back to it if desired. It may also have a flat
or slanting seat to suit Organists or Pianists. It may have an extra seat folded over
the ordinary seat, on the extra seat may hang from the side or sides of the ordinary,
so that by means of legs or bolts the extra seat could be opened out to form a duett

page_text: stool. The action of this stool is applicable to duett stools or foot stools. The seat
of the stool may contain a drawer or box as a receptacle for sheet music or books.
The stool may also be fitted up with one or more Telescope Music stands or desks at
its back or sides as desired. On these Music Desks may be fixed candle sticks or
Lamps. The seat of the Music stool may be made to take on or off, if desired for
the convenience of packing during transit or storage.
Rubber balls or discs may be let in the bottom of two or more of the legs or
feet of the stool, if desired, to prevent any tendency it may have of slipping or
moving when one is playing the Piano or Organ.

EMMANUEL BALL.
I, EMMANUEL BALL, of 112, Lichfield Street, Walsall, in the County of Stafford
Professor of Music, do hereby declare the nature of my said 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 has for its object a new or improved music seat or stool which is
capable of easy adjustment without detriment to its steadiness or stability.
The two sides which are the chief support of the music stool or seat, may
consist of two strips of wood, metal, metal and wood combined, or any other
suitable material. Each of these two strips are pivotted through or at their centre
or thereabouts so as to allow them to open or close as desired. A cross bar may
extend from pivot to pivot if desired by way of strengthening the centre of the
stool. To support the sides or cross legs of the stool at the top and bottom
cross bars may be secured to them. The two top cross bars may be made to
work freely at their ends into the holes made in the sides or cross legs to
receive them so as not to impede the movement of the screw pin which works
through or in conjunction with them. These two top cross bars will each have a
hole bored through them across their centre. The hole in the back cross bar will
be tapped so that a screw pin may be screwed through it into the hole made in the
other cross bar to receive it. The screw pin will have a small wheel or handle at its
outer end to enable one to turn it readily. It will also have a set off or nut and pin
arrangement at the other end by which means it will be permanently attached to the
front cross bar. It will be clearly seen if the screw pin is permanently fixed to
the front cross bar and works or screws freely through the tapped hole or socket of the
back cross bar the moveable sides or cross legs of the stool may be opened or closed
by it at pleasure, which by so doing will raise or lower the seat of the stool as desired.
The seat of the stool will be supported and carried by two cross bars which are fixed
by means of pins or screws to either side of the top of the moveable cross legs or
sides. These two top cross bars to which the seat is fixed will each have a slot or
groove cut in or through them at their one end. These grooved portions will work
on a pivot or pin fixed in either side of the stool and so admit of the seat riding
freely in the top of the moveable sides when they are open or closed for the raising
or lowering of the stool. If desired teeth may be made in the upper portion of the
slots in the slotted bars which carry the seat and a pin fixed in either side of the
stool for the teeth of the slots to fit on; it would then only be necessary to lift and

page_text: push or pull the seat over these pins to raise or lower it. This would dispense with
the screw pin arrangement. If desired the lifting of the slotted hars over the pins.
to raise or lower the seat might be done by means of one or more pins having a
handle in one end and a small cog wheel or lift in the other end being fixed through
the sides of the stool. By turning round these pins the tooth slotted bars may be
lifted backwards or forwards over the side pin and so raise or lower the seat. The
cross legs or moveable parts of the may pivotted an made to move only
from the centre of the stool if desired. The lewer part or feet of the stool would in
this case be always at a fixed distance. The music stool may have a back to it if
desired. It may also have a flat or slanting seat to suit organists or pianists. It may
have an extra seat folded over the ordinary seat or the extra seat may hang from the
side or sides of the ordinary one so that by means of legs or bolts the extra seat
could be opened out to form a duett stool. The action of this stool is applicable to
duett stools or foot stools. The seat of the stool may contain a drawer or box as a
receptacle for sheet music or books. The stool may also be fitted up with one or more
telescope music stands at its back or sides as desired. On these stands may be fixed
candlesticks or lamps. The seat of the music stool may be made to take on or off
if desired for the convenience of packing during transit or storage. Rubber balls or
discs may be let in the bottom of two or more of the legs or feet of the stool if
desired to prevent any tendency it may have of slipping or moving when one is
playing the piano or organ. The socket, screwed or otherwise, may work on a
gymbol so as to accommodate themselves to the various angles required when raising
or lowering the seat by means of the screw. The bar which carries the seat is slotted
and a right and left hand thread screw carrying a groove round its centre is used to
open and close the legs.
In order that my invention may be clearly understood and more easily carried into
practical effect I have appended hereunto a double sized sheet of drawings upon
which I have illustrated examples of the same showing some of the various shapes
and modes of carrying the same into practice and which will enable others to apply
the invention to stools or the like articles.
Figure 1 is a perspective view of one of my stools or stands with its seat and other
parts put together and complete and ready for use.
Figure 2 is a side elevation of the frame of the stool with the top or seat L with
its frame E removed.
Figure 3 is an end elevation of the same stool also with the top L and its box
frame E also removed.
Figure 4 is a plan of the stool frame with the lid or seat L and box frame E also
removed.
Figure 5 is a side elevation of a frame with a single leg or stand arrangement A*
and feet and a which are fast to the stand A2 but having movable upper
parts T, T hung upon pivots b1 b, which are operated by a screw substantially as
applied to the other figures.
Figure 6 is an end elevation of the arrangement shown by Figure 5.
Figure 7 is a perspective view of a stool of slightly different design but with a
single handed screw operating so that only the upper part of one leg traverses the
slot 3.
Figures 8, 9, 10 and 11 show modified forms of the plates P which allow the
legs to be operated and the top lifted without the use of a screw.
My stool or stand frames are generally constructed with cross legs such as are
shown in elevation by Figures 1, 3, 7 and other figures, the legs being pivotted
together by a pivot B which may continue through from one side to the other as
seen at Figure 7 or as seen at Figure 1. This pivot allows the legs to be drawn
together at the top by a screw S which may be single in its action as shewn at
Fiure 7 or double as seen at Figures 1, 2, 3 and 4. Upon the under side of the
seat, which may be box E as shewn at Figure 7 with its lid L, are fixed two
plates P by means of the ears p¹. These plates in the case of the four first figures
carry two slots
in which pins or projections a freely slide and which are fast

page_text: to the tops of the legs A, A'. The legs are coupled together by lower cross bars M
and upper cross bars N. Between the upper cross bars N is hung a screw S which
terminates at one or both ends with a handle H and the screw is connected with the
bars N at each side by a nut. R pivotted at to N. This screw S is notched or
carries a groove 8 at or near the middle in which a forked strut K fits loosely so that
as the screw is operated by the handle H it turns freely in the fork K carrying the
upper part of the legs A and A¹ closer together along the slots p2 in the plates P
thus raising the height of the top or seat L, and in like manner by reversing the
action of the screw S the seat is lowered. Rubber caps or their equivalents may be
fitted on the ends or feet of the legs A and A¹. In Figure 7 the design of the legs
as regards configuration is somewhat different but that may be varied according to
taste in any of the figures shown, but in this Figure 7 there is only one slot p²
in the plate P as the left hand pivot as does not slide and therefore the screw S is
not double ended but the principle is practically the same.
Instead of using a screw, plates such as are shown at Figures 8, 9, 10 and 11 may
be used, for instance the hollows at the top of the slot p2 when the slot or frame E
is lifted will allow the legs to be moved so that the pivots, pins or rods as will take
into the slots, thus regulating the height of the seat L. In like manner one end
only of the frame may be operated by a pinion W working in teeth p³ with a slot p²
as per Figure 8, or the teeth and pinion may be on the under edge of the plate P
as seen at Figure 9, but the effect in all the cases is very similar, namely, to raise
the height of the seat. Or a star pinion may be used so as to tilt or lift the bar as
shown at Figure 11. Or the legs inay be drawn together by means of a band or cord
arranged so as to wrap round one of the bars or other convenient part of the frame
and a spring arranged so as to force the legs apart when lowering the seat.
In the case of Figures 5 and 6 the parts T are pivotted at b¹ b¹ to the pillars A²
and the feet a³ a' are always at the same distance apart, but otherwise the action of
the screw or its equivalent is the same as explained previously except that the plate P
lifts or slides upon the upper portion a" of the legs A¹ in a dovetailed or recessel
portion of P. It will be understood that the design of the stools or stands may
be varied considerably and that any suitable material may be used in the construction.
Though I have explained the invention as applied to music seats or stands, it will be
evident that the same principle is applicable to tables, stands and other purposes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
