Improvements in and relating to Removable Seats for Chairs, Tops
for Tables, and the like.
I, JEREMIAH O'MEARA, a citizen of the United States of America, residing at
Number 1 West Twenty-first Street, in the City, County and State of New York,
one of the United States of America, Engineer, 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 :-
Reference being made to the accompanying drawings, in which―
Figure 1 is a bottom plan view of a chair seat.

Figure 2 is a longitudinal section, taken substantially in the plane of line 2-2,
Figure 1.
Figure 3 is a transverse section, taken substantially in the plane of line 3-3,
Figure 1.
Figure 4 is a perspective view of the stationary and movable parts of the fastening
and adjusting device.
Figure 5 is a perspective view of an auxiliary of the fastening device; and
Figure 6 is a longitudinal section of another form of fastening device.
The object of this invention is to provide means for readily inserting, securing
and adjusting removable seats in the seat-frame of chairs, sofas, settees, and other
objects.
The invention will be best understood by describing its principle as applied to a
chair-seat composed of a rigid stationary frame and having the seat or bottom
member made by upholstering a frame and inserting the said upholstered frame
within the stationary frame from below, and carrying and holding it in place, so
that it may be adjusted or removed at pleasure, by means of fastenings in the nature
of cramps or clamps, comprising a stationary part applied to the stationary frame,
and a movable and adjusting part applied to the upholstered frame and co-operating
with the stationary part, all as I will proceed now more particularly to set forth
and finally claim.
The frame a may be of wood, and of any suitable construction, and preferably
having the adjacent inner edges b of its opening beveled, as shown in Figures 2
and 3. In the instance illustrated in the drawings, I have shown a stuffed seat, or
upholstered seat c, erected upon the frame d, and having the outer edges of its frame
beveled correspondingly with the bevel of the seat frame a.
The devices used for securing the seat in the frame and for adjusting it therein,
comprise a stationary part or keeper e, fixed to the stationary frame, and made as
a socket, and a movable part or bolt fadapted to enter the socketed part of the
keeper and provided with a set-screw 9, which set-screw bears against the frame d
of the upholstered seat so as to cramp or pinch the bolt within the keeper, and, at
the same time, force the upholstered seat home within the seat-frame a. In order
to provide a bearing for the point of the screw against the frame d, I may sink into
the said frame the button or wear-plate h, or, as shown in Figure 6, said button
or wear plate may be carried by the screw g, the shank or tang i being inserted
na socket in the point of the screw and following the screw in its adjustment in
he bolt f.
Two or more of these fastenings may be used at opposite points to secure the seat
vithin its frame.
