Improvements in Chair Seats.
I, ANDREW JACKSON KING, residing at 245 West Houston Street, New York, in
the County of New York, and State of New York, United States of America, Show
Card Writer, 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:-
This invention relates to chair seats, and the object thereof is to provide a chair
with a seat which consists of a frame, and a detachable seat proper which is adapted
to be locked in the frame, and to be removed therefrom whenever desired; a
further object being to provide a chair with a detachable seat whereby different
styles of seats may be employed when desired.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which :;
Fig. 1, is a plan view of a chair made according to my invention;
Fig. 2, a bottom plan view of the seat removed; and,
Fig. 3, a transverse section on the line 3, 3, of Fig. 2.
In the drawing forming part of this specification, the separate parts of my
improvement are designated by the same numerals of reference in each of the
views, and in said drawing, I have shown, reference being made to Fig. 1, an
ordinary chair provided with a seat composed of a frame 5, in which is formed a
central opening 6, and said opening in the form of construction shown is
angular in form, and at the front and back thereof, and at the opposite sides are
inwardly directed flanges 7.
I also provide a seat proper which is designated by the referencè numeral 8,
and which is so formed as to exactly fit within the opening 6, in the frame 5, and
said frame is provided with downwardly directed shoulders or projections 9, which
are preferably semi-circular in form, and one of which is formed on or secured
to each side of said seat S, and I also provide a screw or bolt 10, for each of said
shoulders or projections, and these screws or bolts are each provided at their lower.
ends with beveled catches or thumb nuts 11, and when said thumb nuts are turned
into the position shown in Figs. 2, and 3, they will securely lock said seat proper
within the frame 5, and when turned at right angles to the position shown in said
figures, the seat proper may be removed from the frame 5, as will be readily.
understood.
:
The seat proper may be upholstered as shown in Fig. 3, or it may be formed in
any desired manner, and instead of forming the opening. 6, in which the seat
proper is mounted angular in form, it may be circular or of any desired form in
which event the seat proper will necessarily be of the same form.
My improvement is simple in, construction and operation, and is perfectly
adapted to accomplish the result for which it is intended; and it will be apparent
that changes in, and modifications of the construction herein described may be
made without departing from the spirit of my invention or sacrificing its
advantages.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A seat for chairs comprising a frame, and a seat proper mounted therein,
and detachable therefrom said seat proper being provided with downwardly
directed shoulders or projections which pass through the bottom of the frame,
and which are provided with thumb nuts which are adapted to be turned so as
to engage with the bottom of said frame, substantially as shown and described.
2. A chair provided with a seat consisting of a frame in which is formed an
opening, and a seat proper mounted in said opening, and detachable from said
frame, said frame being provided at the bottom of said opening with inwardly
directed flanges on which the seat proper rests, and said seat proper being also
provided with downwardly directed lugs or projections which extend downwardly
to the bottom of the frame, and which are provided with pivoted catches which
are adapted to be turned so as to engage with the bottom of said frame, sub-
stantially as shown and described.
