Improvements in Revoluble Seats.
I JOSEPH MEES of Comberton Villa Brettle Lane in the County of Stafford,
Professor of Music, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in revoluble seats to be more particularly
used in connection with pedal organ stools the object being to facilitate the using
of the pedals by enabling the performer to turn upon a fixed centre and thus
reach the pedal keys to the right or left without moving about on the stool
and getting out of a central position as is usual with organ stools as hitherto
used.
My revoluble seats may be used in connection with chairs, or stools other than
organ stools when a revoluble motion is required.
My said invention consists in constructing a revoluble seat by means of a top and
bottom plate the top plate being revoluble upon rollers or balls which convey the
weight to the bottom plate the rollers or balls being placed in as large a circle as the
plates will admit the top plate is revoluble with a steady movement and prevents any
rocking or unsteady motion the two plates being kept together by a central pin
having screwed ends or collars and cotters.
I JOSEPH MEES of Comberton Villa, Brettle Lane in the County of Stafford
Professor of Music 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 revoluble seats to be more particularly
used in connection with pedal organ stools, the object being to facilitate the use of
the pedals by enabling the performer to turn upon a fixed centre and thus reach the
pedal keys to the right or left without moving about on the stool and getting out of a
central position as is usual with organ stools as bitherto used. My revoluble seats may

motion is required. In order that my invention may be clearly understood, reference
is made to the accompanying drawings in which Figures 1, 2, 3, and 7, are plan
views of the bottom plate, Figures 4, 5, and 6, are sectional views through the centre
of the top and bottom plates of the improved revoluble seat. Figure 8 represents
the central pin enlarged. The same letters of reference indicate the same parts in
the several figures of the drawings. Figure 1, represents a bottom plate a,
having a groove b, filled with the balls c. Figure 2, represents a bottom plate a,
having rollers d to revolve on centre pins in the frames e, e, e. Figure 3, represents
a bottom plate a, having rollers f, with centre pins f¹, to revolve in holes in the
concentric rings g g, the said rings revolving with the rollers and keeping them apart.
Figure 7 represents a bottom plate a, with the groove b, partly filled with balls c, and
having distance pieces h, to keep them apart. Figure 4 represents a section through a
bottom plate a, and a top plate a', having balls c, in groove b, and the central pin j
(see Fig. 8). Figures 2, 3, and 7, in plan view, represent the bottom plate a open
at k, k, k, k, and a cross piece m for holding the central pin. Figures 5, and 6,
represent openings k, k, k¹, k¹, through the bottom plate a, and the top plate a¹, and
the cross piece m, m, in the bottom plate a, and the top plate a', having the seat
portion,, formed of cane, wood, or other suitable material. Figure 8 represents
the central pinj having a collar n, a peg o, a squared or angular boss p, to prevent
the central pin turning, and a screw nut q with spring washer 1. Instead of the
collar n, and peg o, the top end of the central pin may have a screwed end, and nut
with lock nut. I will now describe the use of the central pin j (see Fig 8). The
squared or angular boss p, on the pin, and the collar n, and peg o, or nut with lock
nut, hold the bottom plate a, and top plate a¹ together, and when the screw nut q is
tightened the washer is pressed against the underside of the cross piece m, or
against the underside of the bottom plate a, Fig. 4, and pulls down the central pin and
collar n, or nut with lock nut, on to the cross bar s which is secured to the top
plate a', see Figures 5, 6, and 8, or against the plate t, which is secured to the
underside of the top plate a', see Fig. 4, and produces friction between the collar n,
the cross bar 8, and the washer u, see Figures 4, 5, 6, and 8, and prevents the top
plate turning too freely and the friction may be varied by slackening or tightening
the screw nut q. Figure 4 represents the groove b wholly in the bottom plate a, but
instead of this the groove may be wholly in the top plate a¹, or a groove may be in
the top plate a¹, and also a groove in the bottom plate a, each groove being of the
proper depth to give a space, when the balls are in place to form a clearance
between the inner surfaces of the top and bottom plates. The rollers d, represented
in Figures 2, and 5, having the frames e, e, e, placed in the bottom plate a, may
instead of this, be placed in the top plate A¹. I do not limit myself to the
number of balls, or rollers, that may be used in my revoluble seat, neither do I
limit myself to the top and bottom plates being round, they may be of any
contour desired, and instead of the seat portion being formed on the top plate a¹,
a separate seat portion such as an ordinary chair bottom or stool top may be placed
upon the top plate a¹.
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:-
1. In a revoluble seat the combination of parts whereby the top part is revoluble with
a steady movement free from any rocking or jolting motion, (and may be used in
connection with pedal organ stools, or in connection with ordinary stools or chairs,)
substantially as hereinbefore described and illustrated.
2. In a revoluble seat the combination of a top and bottom plate, the top plate
being revoluble upon rollers, or balls, which convey the weight to the bottom plate,
substantially as herein before described and illustrated.
3. In a revoluble seat the combination of parts whereby the top plate may be made

page_text: to turn or revolve freely, and easily, or with variable friction, by means of an
adjustable central pin having screw, a nut, and washer, substantially as hereinbefore
described.
