PROVISIONAL SPECIFICATION.
Improvements in and relating to Stools or Seats.
I, JOHN REID, of 5 Madiera Court, Glasgow, Lanarkshire, Cabinet Maker, do
hereby declare the nature of my invention to be as follows:-
This invention has reference to and comprises a new or improved construction or
arrangement and combination of the parts of a stool or portable seat which can be
raised or lowered to any desired height convenient for sitting before a piano, organ,
or otherwise, and which can be folded and packed into small space for transit or
removal:
The improved stool consists of an upper seat frame which may have cushions,
and projecting arms much as usual. But by my improvements there is fitted on
the under surface of this seat frame two sliding horizontal frames. These frames.
are preferably fitted with longitudinal rails on each side formed with grooves or
chaunels which engage with and slide over projecting feathers or ribs formed on the
under side edges of the seat frame. Four legs are preferably fitted to the stool
and are mounted at their upper ends on transverse rails or rods, secured at the outer
ends of the sliding frames, and the pair from each rail pass diagonally across and
are screwed or secured to those from the opposite rail near the centre of their
length, and each pair of rails may be stayed near their lower end: A longitudinal
projecting edge bar or rib would be formed on or secured to one of the sliding
frames preferably at the centre to slide in the groove or channel between two corre-
sponding parallel bars formed on or secured to the other sliding frame; and these
bars would be formed with a series of transverse holes so that a locking pin may
be passed through them and look the frames and legs in any desired position to
suit the height of stool or seat desired. The locking pin may be attached by a
chain, or it may be operated by a hand lever or a lever and spring. When the
stool is to be packed for transit the two sliding frames would be extended out in
opposite directions from each other to their extreme out position, and the legs
would then fold over to a nearly horizontal position. Suitable stops such as
projections on the grooves would be fitted for holding the horizontal sliding frames
in their extreme outer position. The working parts may be made either of wood
or metal or a combination of both, and the projecting feathers may be formed on
either the inside or outside surface of the side rails of seat frame for the grooves.
of movable frames to slide on.

COMPLETE SPECIFICATION.
Improvements in and relating to Stools or Seats.
I, JOHN REID of 5 Madiera Court, Glasgow, Lanarkshire, Cabinet Maker, do
hereby declare the nature of my invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement in writing that is to say :-
This invention has reference to and comprises a new or improved construction or
arrangement and combination of the parts of a stool or portable seat which can be
raised or lowered to any desired height convenient for sitting before a piano, organ,

page_text: or otherwise, and which can be folded and packed into small space for transit or
removal.
And in order that my said invention and the manner of carrying same into
practice may be properly understood, I have hereunto appended an explanatory
sheet of drawings, in which
Figure 1 is a side elevation of a stool or seat as fitted with adjustable sliding
frames in accordance with my improvements.
Figure 2 is an inverted plan view corresponding to Figure 1 showing the under
surface of the sliding frames and their fittings. And
Figure 3 is an end elevation corresponding to Figure 1.
Figure 4 is a detached section showing the side rails of the sliding frames as
formed of dovetail or channel shape to fit within corresponding recessed rails on
the fixed seat frame.
And
Figure 5 represents detached views of the hand operating spring lever. While
Figure 6 represents a view of an alternative arrangement for operating the
adjustable sliding frames.
Referring to these drawings:-
The improved stool consists of an upper seat frame A which may have cushions A
and projecting arms A' much as usual. But by my improvements there is fitted
on the under surface of this seat frame two sliding horizontal frames B, B'. These
frames are preferably fitted with longitudinal rails b, b, on cach side which
engage with and slide over projecting feathers or ribs a, a, formed on the
under side edges of the seat frame A. Or as shown in detached section Figure 4
the longitudinal rails b, b, may be formed of dovetail or channel metal section, to
slide within corresponding shaped metal rails or recesses a, a, on the fixed seat
frame A. Four legs C, C, are preferably fitted to the stool and are mounted at
their upper ends on. transverse rails or rods c secured at the outer ends of the rails
or of the sliding frames B, B, and tho pair from each rail b pass diagonally across
and are screwed or secured to those from the opposite rail near the centre of
their length by a transverse stay C' and end screw nails, and each pair of legs C
may be stayed' near their lower end by transverse stays C. A longitudinal pro-
jecting edge bar or rib b would be formed on or secured to one of the sliding fraines
as. B preferably at the centre to slide in the groove or channel between two
corresponding parallel bars formed on or secured to the other sliding frame B¹
and these bars would be formed with a series of transverse holes & so that a locking
piu d may be passed through them and lock the frames B, B', and legs C, C, in
any desired position to suit the height of stool or seat desired. The locking
pind may be attached by a chain, but would preferably be operated by
a hand
lever d' fulcrumed at d which would press the head of the pin d out against a
blade spring d³ fulcrumed at and the recoil of which when the hand lever d' is
released would press the pin d into the holes 6" opposite it. Instead of adjustably.
securing the eliding frames B, B' by slotted edge bars or ribs and a locking pin
or lever, this may be effected in an equivalent manner as shown in Figure 6 by
screwed spindle and screw nuts. In this arrangement the spindle B would be
formed with right and left hand screws d, d' respectively and work through screwed
nuts or eyes D', D', on the sliding frames B, B, and through a guide bearing
nut Dou the seat frame A and a handle D' would be fitted on the free end of
screw spindle I' to operate sume and bring the sliding frames B, B' towards or from
each other. When the stool is to be packed for transit the two sliding frames B, B¹,
would be extended out in apposite directions from each other to their extreme out
position, and the legs C would then fold over to a nearly horizontal position.
Suitable stops such as pins c' on the sliding frames B, B', to work in grooves cl
in the seat frame A would be fitted for holding these horizontal sliding frames B, B
in their extreme outer positions. The working parts may be made either of wood
or metal or a combination of both and the projecting feathers may be formed. on
either the inside or outside surface of the side rails of seat frame for the grooves of
movable frames to slide in.

page_text: 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:
First. A stool or seat in which the upper ends of the legs are connected to two.
sliding frames which can be adjusted to raise or lower the height of seat and be then
looked in any desired position, substantially as set forth.
Second. In a stool or seat, the combination comprising adjustable sliding frames,
side rails on said frames sliding at sides of seat frame, and an adjustable and locking
device, substantially as set forth.
Third. In a stool or seat the combination comprising two sliding frames, a central
projecting rib formed on under surface of one of said frames to work between two
corresponding ribs formed on the other frame, and a looking pin to pass through
any one of a series of holes formed in said ribs, substantially as set forth.
Fourth. In a stool or seat, the combination, comprising two sliding frames,
formed with projecting ribs or under surface, and a hand lever and spring to
operate a locking pin which passes through holes formed in said ribs, substantially
as set forth.
