PROVISIONAL SPECIFICATION.
Improvements in Chairs.
I, JOHN HARRINGTON of the Enamel and Cradle Spring Works, Coventry, in the
County of Warwick, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
The invention has for its object improvements in chairs, and relates to means for
supporting the seat and back so as to afford great ease and comfort to the
occupant.
For this purpose I employ a stationary frame or base of any suitable construction
to carry the seat and back. This stationary frame or base is formed with fixed arms
and with or without a fixed back frame.
The seat and back may be made in any suitable manner and upholstered according
to taste. The said back and seat, which in effect are like the corresponding parts of
an ordinary chair deprived of its legs or lower frame, are suspended by springs
of any suitable character from the fixed arms and from the fixed back frame, when
such is used.
I also attach to the seat and to the fixed frame suitable check springs, which will
prevent the seat from tipping unduly in any direction.
When employing a fixed back frame, it will be formed so as to permit the back of
the chair carried by the seat to freely move within certain limits in any direction.
The springs employed to support and control the motion of the seat and back may
be ordinary coiled springs, in which case I encase then in suitable covering tubes or
otherwise protect them so as to prevent injury to the persons or dress of the
occupants of the chair. Or such springs may be formed of india rubber, either in
cylindrical or sheet form; or springs of any suitable material and construction may
be employed.
===
If desired the seat and back may also be provided with arins fixed thereto, so that
whatever position the seat and back may assume, the said arms will always retain the
same relative position thereto.
The fixed frame may also be formed to terminate at or about the level of the seat,
in which case the latter would be provided with downwardly projecting arms or
frame, to the lower end of which the supporting springs would be attached, the upper
ends of such springs being fixed to the upper part of the fixed frame.

COMPLETE SPECIFICATION.
Improvements in Chairs.
I, JOHN HARRINGTON of the Enamel and Cradle Spring Works, Coventry in the
County of Warwick, Manufacturer do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement, reference being had to the accompanying
drawings and to the figures and letters marked thereon:-
The invention has for its object improvements in chairs and relates to means for
supporting the seat and back so as to afford great ease and comfort to the occupant.
Figure 1. is a side view and Figure 2 is a front view of a chair constructed
according to my invention and Figure 3. is a cross section of parts thereof.
In carrying my present invention into effect I employ a lower frame, or base a of

page_text: any suitable construction to carry the seat b and back c. This lower frame, or base a
is formed with fixed arms a' and it may be formed either with or without a fixed
back frame.
The seat, and back c may be made in any suitable manner and upholstered accord-
ing to taste. The said seat b, and back c, which in effect are like the corresponding
parts of an ordinary chair deprived of its legs or lower frame are suspended by
springs d of any suitable character either from the fixed arms a¹ or from stretchers a²
fixed to the lower frame or base just below the arms a' and in cases where a fixed
back is attached to the lower frame or base a the seat & may be partially carried by
springs attached thereto and to the said fixed back.
I also attach to the seat band to the fixed frame or base a, suitable check springs e e
which will prevent the seat a from tipping or swinging unduly in any direction.
When employing a fixed back frame it will be so formed and arranged as to permit
the back c of the chair carried by the seat b to freely move within certain limits in
any direction.
The springs de employed to support and control the motion of the seat band back c
may be as shown in the drawing, ordinary coiled springs in which case I encase them
in suitable covering tubes or otherwise protect them so as to prevent injury to the
persons or dress of the occupants of the chair. Or such springs may be formed of
india rubber either in cylindrical or sheet form or springs of any suitable material
and construction may be employed.
If desired the seat 6 and back c may be also provided with arms fixed thereto as
will be readily understood so that whatever position the seat band back e may assume
the said arms will always retain the same relative position thereto.
The fixed or lower frame or base a may also be formed to terminate at or about the
level of the seat b when the chair is in use in which case the latter would be provided
with downwardly projecting arms or frame to the lower parts of which the supporting
springs & would be attached, the upper ends of such springs being fixed to the upper
part of the fixed frame a.
The drawing represents the chair unupholstered for the sake of clearness but it will
be readily understood that the chair will be suitably covered and upholstered to render
the springs invisible.
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:-
In the construction of chairs, a fixed or lower frame or base with or without arms
and back in combination with a seat and back, provided or not with arms, suspended
from the fixed or lower frame or base by springs substantially as herein shown and
described.
Dated January 3 1890.
