Improvements in and relating to Chairs, Stools, and such like
Articles.
I, JAMES BROWN of Newfield Works, Rutherglen County of Lanark North
Britain Cabinet Maker do hereby declare the nature of this invention to be as
ollows:-
Ch
It relates to chairs stools and other such like articles, more especially to those
articles which are known as adjustable baby chairs" and has for its chief
objects:
1st. To adapt such a chair for being raised lowered and adjusted at any required
elevation:
2nd. To adapt such a chair for being turned round with greater ease than
hitherto possible :
3rd. To adapt such a chair for being separated from its supporting base or
pedestal:
4th. To adapt such a chair for being used apart from its supporting pedestal or
the said base apart from the chair:
5th. To adapt such a pedestal or base for serving the various purposes of a chair-
support, stool, table or rocking appliance:
6th. To adapt the back and foot rests of such a chair for being fixed at any
required angle.
7th. To unite a bracket tray to the arms of such a chair without obscuring
their design.
In carrying out this invention in connection with an adjustable baby chair the
said chair is fitted upon a base or pedestal which consists mainly of four adjustable
legs pivotted to an upper frame, the latter being composed principally of a top and
two sides, the aforesaid legs being united together as hereafter described for
simultaneous, conjoint action.
Two of the said legs are pivotted to one side of the upper frame and two on its
opposite side. Each leg is united by means of rails or bars to a corresponding leg
on the opposite side of the upper frame.
The side parts of the upper frame are shaped, when required, as rockers, each
containing an open longitudinal space in which two of the said leg rails move.
One or more longitudinal screws is or are fixed to these last named leg rails and to
one or more fixed staples beneath or near the top. As an alternative arrangement
a screw is fixed to the pedestal and made to engage with one or more toothed
wheel racks or quadrants upon the leg or legs for the purposes hereafter named.
A single screw containing both right and left hand threads is sometimes used for
the said purposes. Such screw or screws being actuated with a handle key or
wheel moves or move the said rails towards or from each other causing each pair
of legs to rotate upon their pivots and move thein wider apart from or nearer to
the other pair, thereby lowering or raising the whole base or pedestal. When the
legs are fully expanded this pedestal rests upon the two sides (or rockers) of the
upper frame only.
The baby chair is mounted upon this pedestal in one or more of the following
ways: In one way the top of the pedestal forms the seat of the chair, the back
arms and foot-rest being united thereto in any ordinary manner or as hereafter

page_text: described in another way a complete baby chair is made of any suitable pattern
and fitted immoveably or removeably upon the aforesaid pedestal: a further
variation consists in making a baby chair of suitable dimensions and form and
pivotting it to or upon the top of the said pedestal so that the chair can be
revolved thereon as required.
In carrying out the improvements whereby my sixth object is effected the chair
arms are pivotted to its back frame and foot-rest-supports, and the back frame and
foot-rest-supports are similarly united to the chair seat the whole of these
pivotted or hinged members of the chair proper move together simultaneously but
are controlled, operated and fixed in any required position or at any required angle
by means of a screw, ratchet or other mechanism engaging with or connected to
one or more of the pivotted joints, so that as the screw is revolved the said
mechanism is put in motion and all the pivotted parts are simultaneously moved in
a slow and gentle manner, free from sudden jerks or impulses.
The bracket tray is connected to the arms of the said baby chair by means of
jointed or other rods attached to the tray and fitted into holes of corresponding
dimensions which are bored lengthwise in the chair arms.
The pedestal or base, adapted for being fixed at various heights as herein
described is designed for use also, when not connected with a baby chair, as a
child's table stand music or other stool.
The removeable baby chair before named is designed in some of its forms for use
as a low baby chair when it is detached from the said pedestal or base.

COMPLETE SPECIFICATION.
Improvements in and relating to Chairs, Stools, and such like
Articles.
I, JAMES BROWN of Newfield Works, Rutherglen County of Lanark North
Britain Cabinet Maker 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:-
It relates to chairs stools and other such like articles, more especially to those
articles which are known as "adjustable baby chairs" and has for its chief objects:
1st. To adapt such a chair for being raised lowered and fixed at any required
elevation ;
2nd. To adapt such a chair for being turned round with greater ease than
hitherto possible;
3rd. To adapt such a chair for being separated from its supporting base or
pedestal;
4th. To adapt such a chair for being used apart from its supporting pedestal or
the said base apart from the chair;
5th. To adapt such a pedestal or base for serving the various purposes of a chair
support, stool, table, or rocking appliance;
6th. To unite a bracket tray to the arms of such a chair without obscuring their
design.
In carrying out this invention in connection with an adjustable baby chair the
said chair is fitted upon a base or pedestal which consists mainly of four adjustable
legs pivotted to an upper frame, the latter being composed principally of a top and
two sides, the aforesaid legs being united together as hereafter described for
simultaneous, conjoint action.
Two of the said legs are pivotted to one side of the upper frame and two on its

page_text: opposite side. Each leg is united by means of rails or bars to a corresponding leg
on the opposite side of the upper frame.
The side parts of the upper frame are shaped when required, as rockers, each
containing an open longitudinal space in which two of the said leg rails move.
One or more longitudinal screws is or are fixed to these last named leg rails and to
one or more fixed staples beneath or near the top. A single screw containing both
right and left hand threads is sometimes used for the said purposes. Such screw or
screws being actuated with a handle, key or wheel moves or move the said rails
towards or from each other causing each pair of legs to rotate upon their pivots
and move them wider apart from or nearer to the other pair, thereby lowering or
raising the whole base or pedestal. When the legs are fully expanded this pedestal
rests upon the two sides or rockers of the upper frame only. The baby chair is
mounted upon this pedestal in one or more of the following ways: In one way the
top of the pedestal forms the seat of the chair, the back arms and foot-rest being
united thereto in any ordinary manner or as hereafter described in another way
a complete baby chair is made of any suitable pattern and fitted immoveably or
removeably upon the aforesaid pedestal: a further variation consists in making a
baby chair of suitable dimensions and form and pivotting it to or upon the top of
the said pedestal so that the chair can be revolved thereon as required.
The bracket tray is connected to the arms of the said baby chair by means of
jointed or other rods attached to the tray and fitted into holes of corresponding
dimensions which are bored lengthwise in the chair arms.
The pedestal or base, adapted for being fixed at various heights as herein
described is designed for use also, when not connected with a baby-chair, as a
child's table, stand, music or other stool.
The removable baby chair before named is designed in some of its forms for use
as a low baby chair when it is detached from the said pedestal or base.
This invention will be better understood if reference is made to the accom-
panying drawings in which :-
Figure 1. is a view in elevation shewing a removeable baby chair made in
accordance with this invention arranged upon a pedestal suitably for rocking with
a cradle motion.
Figure 2. is a view in elevation shewing the pedestal described herein separated
from the chair and adapted for use as a rocking horse appliance.
Figure 3. is a view in perspective shewing the baby chair described herein
removed temporarily from the pedestal.
Figure 4. is a view in elevation shewing the table for the baby chair described
herein, removed from the chair.
Figure 5 is a plan shewing one modification of the baby chair screw adjusting
devices described herein.
Figure 6 is a side view in elevation shewing the removeable revolving baby chair
and pedestal described herein combined and in their highest positions.
Figures 7. and 8. are views of details for attaching, locking and revolving the
chair or other article upon the pedestal as described herein.
Figure 9. is a perspective view of a baby chair and pedestal, made in accordance
with this invention.
Figure 10. is a perspective view of a pedestal, stool or stand made in accordance
with this invention.
Figure 11. is a side view in elevation of a pedestal and chairs arranged as a
see-saw rocking appliance.
Similar letters of reference and numerals, throughout these drawings indicate
corresponding parts.
Referring to the drawings, the two curved legs A are united together by the
rigid rails a' and the rotating bar a whilst the two marked B are similarly united
by the rigid rails 6' and the rotating bar 62. Two of these legs A-B are united to
the side C and the other two to that marked c¹ by means of pivots a³ and 63.
The sides C and care curved as rockers on their under parts when combined with

page_text: a baby chair and are united to the top D: this combination of top D sides Cand
legs A-B thus united together, constituting a stool table or pedestal for a baby
chair in accordance with this invention.
In one modification of this invention a baby chair is constructed upon the top D
Figure 9, with arms E back Fand supports G and with or without a tray or
table H and foet rest J; this chair is not removeable from the pedestal: it can be
lowered from the high position shewn in Fig. 9. until the legs A-Bare lifted from
the ground and the chair rests upon the rockers C by means of the screw and the
handle connecting the rotating bars a² and together. As the screw a is
revolved the said bars are drawn closer together and they acting through the
pivots a rotate the legs A-B upon the pivots a³ and until the low position
shewn in Figs. 1, 2 and 11 or any intermediate position is attained. The smooth
guide bars a Fig. 9 are fixed to one of the rotating bars a or and work in holes
of suitable shape and size formed in the opposite one: these acting in conjunction
with the toothed quadrants fixed upon A-B insure a steady parallel motion of
the bars and prevent any injurious strain upon the screw a which is threaded
into one of the rotating bars only. A slight midification of these screw devices is
shewn at as in Fig. 5: this screw has a right & left thread with centre collar
part a controlled by one or more staples a fixed to a cross bar e; each part of
the screw is threaded into a bar a 12. This screw is extended when required as
shewn in Fig. 5 and fitted with a handle such as a' Fig. 9: or if desired with a
wheel a or with both wheel and handle a" a Fig. 5. By means of these screw
devices this pedestal or pedestal and chair is lowered, raised and fixed at any
elevation required between the highest and lowest possible positions.
The pedestal shewn in Figure 10 has a top D fitted upon rocker shaped
sides C. and united to legs A-B furnished with screw operating devices as
described with reference to Figures 5 & 9 but in addition thereto has a hole d'
pierced through the top for the purpose of enabling it to be united to one or
more removeable baby chairs or rocking appliances as shewn in Figures 1. 2. 6
or 11.
The sides C, c are made in one piece each as shewn in Figs. 1 and 10, or in
more than one piece each as shown in Figs. 9 and J. The baby chair shewn
in Figure 3 is adapted for being attached to the pedestal described with reference
to Fig. 10, so that it can be fixed in a variety of ways and positions and revolved
thereon. A board (or frame) Figures 1, 3, 6 and 7. is fixed beneath or to the
chair seat and the chair feet d³ depend to any suitable extent below for giving
height to the chair when it is used apart from the pedestal. This board or frame d
is designed to rest upon the top D Figures 1, 2, 6 or 10, and in one modification of
the devices for attaching this chair to the pedestal shewn in Figure 10 a hole is
made in to correspond with that marked Figure 10 and the chair and
pedestal are united together by means of a screw passed through the said holes and
a wing-nut screwed thereon as shewn in the detail Figure 8. This chair Figure 3
is when thus attached adapted for being turned round in any position upon the
top D.
In Figure 1. the position of the chair upon the pedestal is the transverse
of that shewn in Figure 9 so that when rocking a child seated in the chair as shown
in Figure 1 the motion felt by the child resembles that of a cradle-namely from
side to side and not from front to back.
Another simple device, consisting of a pin and cottar d' is shewn in Figs. 8 and 11
for pivotting and fixing the chair Figure 3 to the top D and in Figures 6 and 7
another device is shewn for more rapidly attaching an I disconnecting the chair and
pedestal. This consists of a staple fixed upon the board or frame and a piu
or plunger d' is fitted thereto with sufficient length to protrude above the staple
and beneath the top D: the part marked is a head and a couical end and
neck, it is furnished with a spring for imparting automatic action to it.
The shear shaped spring Figure 7 is fixed beneath so that when the
plunger is pressed down through and the shear bows are pressed together
the conical head passes through the eye d and the neck is enclosed within this

page_text: eye, when the bows are released. This lateral spring sometimes consists of only one
of these shear sides or a simple spring of other form moving laterally. When this
lateral spring is pressed back from the neck part of " the pin d³ is released and
springs out of the hole d' thereby disconnecting the chair and pedestal and adapting
them for being separated. The staple d' is fixed to D and the lateral spring 1 to
the board or frame when the conditions of the chair spaces render it necessary.
A great variety of simple equivalents can be employed in place of the uniting and
disengaging appliances shewn herein.
The baby chair shewn in Fig. 3. or other design is sometimes pivotted immoreably
to the pedestal top D so that it may revolve thereon but cannot be separated
from it the pendant feet are not then required and the design is altered
accordingly.
Fig. 11 represents this improved pedestal with a board K fixed upon the top D
by a pin and cottar suitably for the attachment of two baby chairs by means of
the devices before described for the purpose of enabling the children to engage in
see-saw rocking.
In Figure 2 a hobby horse is shewn attached by temporary removeable appliances
to the top D and indicates a further purpose for which this improved pedestal is
designed.
The table or tray marked H' in Figures 4 and 6 has two jointed rods h² for
insertion within the chair arms E which are bored with round holes when the
rods are round or grooved to suit rods of other sections. A notch h³ at the rear
end of one rod engages with a screw or pin 4 inserted across the bore for the
purpose of retaining the table in its position. In order to withdraw the table the
rear end of the rod is raised until the notch 3 is clear of the pin when the rods
can be withdrawn completely from the arms or sufficiently to allow the table
to hang down as shewn in Figure for convenience of packing and other
purposes.
The table rests upon the step e' when the rods are fully inserted within the arms
and is thereby rendered firm and secure from tilting. If the groove in the chair
arm is a rectangular and oblong one the arm is made in two parts the groove being
formed in one part and covered by the other.
A foot rest J of any ordinary shape or kind is combined with this baby chair
when required also small wheels W are combined with the legs of the pedestal
when required.
The rotating bars of the pedestal shewn in Figure 6 operated by means of a
screw a (or a) are pivotted at to the legs A B, below the level of the rocker
sides C, c'.
I am aware that previous to my invention adjustable rocking carriage baby
chairs have been made which could be lowered, raised and fixed at various heights
by means of one or more screw toothed quadrants, wheels and handles for operating
same, also that desks, stands and music stools have been made with vertical screen
appliances for purposes of elevation and that dining tables have been made with
horizontal screw devices for lengthening and shortening purposes it will
therefor be understood that I do not claim any of these things broadly as my
invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the saine is to be performed I declare that what I
claim is :-
First. In an adjustable rocking or carriage baby chair the combination therewith
of the screw operating and adjusting devices described herein with reference to
Figure 9 of the drawings, or any mere modification thereof for the purposes
specified.
Second. In an adjustable rocking or carriage baby chair the combination
therewith of the screw operating and adjusting devices described hereiu with
reference to Figure 5 of the drawings or any mere modification thereof.

page_text: Third. In an adjustable stool, table, stand or pedestal the combination therewith
of the legs A B top D sides C, and screw raising, lowering and fixing devices
as described herein with reference to the drawings or any mere modification
thereof.
Fourth. In an adjustable baby chair rocking pedestal the combination therewith
of the screw operating devices and the chair connecting and separating devices
all substantially as described herein with reference to the drawings or any mere
modification thereof.
Fifth. In a baby chair the combination therewith of the devices for separating
it from and connecting it to an adjustable pedestal or base all substantially
as herein described with reference to the drawings or any mere modification
thereof.
Sixth. In a baby chair the combination therewith of the devices for separating
it from, connecting it to, and revolving it upon an adjustable pedestal or
base all substantially as herein described and drawn or any mere modification
thereof.
Seventh. In a baby chair the combination therewith of tubular arms all
substantially as herein described and drawn or any mere modification thereof for
the purposes specified.
Eighth. In a baby chair the combination with its tray or table II' of the jointed
arms, all substantially as herein described and drawn or any mere modification
thereof for the purposes specified.
