I, GEORGE ALEXANDER DALLAS, 11, Nuttall Street, Hoxton, Manfacturor, do
hereby the nature of this invention to be as folows:-
Consists of arin stay brace rail of wood or any other suitable material going
croosswise under seat connected to arm stumps to right & left of arms the stumps
are connected to under side of arm by plates of metal iorn or brass acting has
hinges to arms the arms are connected to back legs & seat by rivets bolts or
screws as prefered the arms work on three centers back legs under arm & sent
& in the ordinary are easily strained by being pressed on heavily which makes
them loose in a short time the bar being connected to stumps of arms makes them
rigid & firm additional strength can be given by screwing small metal brackets
to crooss bar & stumps if required. By the use of my invention there is no incon-
veinance caused in opening or closeing of chair all working harmonously
together & overcomes a weakness that all folding chairs have been subgect to
since folding chars have been made were the arm works on three centers here in
described to allow of the chair folding & must be an acknowledged improvent

I, GEORGE ALEXANDER DALLAS, of 19, Nuttall Street, Hoxton, Manufacturer,
do hereby declare the nature of this invention and in what manner the same
to be performed, to be particularly described and ascertained in and by the
following statement:―
"
It consists of an arm stay brace rail "A of wood or any other suitable material,
going crosswise under the seat, connected to arm stumps or struts to right and
left of arms. In chairs of this type the stumps are connected to underside of
arms by plates of metal, iron or brass, acting as hinges to arms. The arms are
connected to back legs and seat by rivets, bolts, or screws, as preferred. The
arms work on three centres, back legs under arm and seat, and in the ordinary
way are easily strained by being pressed on heavily, which makes them loose
in a short time, but my bar being connected to stumps of arms, makes them
rigid and firm. Additional strength can be given by screwing small brackets to
cross bar and stumps if required.
By the use of my invention there is no inconvenience caused in opening and

ness that all folding chairs have been subject to since they have been made where
the arms work on three centres, as herein described, to allow of the chair folding;
and it must be an acknowledged improvement to all users of folding chairs where
arms are used for giving them strength and making them rigid and firm.
This invention relates to all folding chairs of one fold, known and termed as
being on the Boston" principle.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:-
