PROVISIONAL SPECIFICATION.
Improvements in Brackets for Writing and other Tables, Flaps,
Shelves, Seats, and the like.
We, ALBERT BARKER, of New Bond Street, Silversmith, and THOMAS HAYDON,
of 24 Camden Street, Islington, Cabinet Maker, both in the County of London, do
hereby declare the nature of this invention to be as follows:-
This invention relates to that class of bracket in which one hand only is necessary
to effect the raising and lowering of the flap to be supported by the bracket.
For this purpose the upper part of the centrally hinged mainstay is slotted, and
through this slot works a short stay which, at its rear end, is hinged to the underside
of the flap to be raised or lowered, and, at its fore end, terminates in a finger piece
formed with shoulders.
When this finger piece is raised in order to lower the flap, the shoulders, after a
certain amount of travel, strike against the uppermost portion of the centrally hinged
mainstay and thus cause said mainstay to fold inwards on its hinge and the flap to fall
at a right angle to the ledge to which it is hinged. The hinge connecting the short
stay to the under side of the flap is a spring binge, so that directly the flap is raised,
and the finger piece released, this short stay falls to the lower end of the slot and thus
maintains the mainstay rigid and the flap in its raised and horizontal position. When
the flap is closed, the short stay abuts against the upper end of the slot.

COMPLETE SPECIFICATION.
Improvements in Brackets for Writing and other Tables, Flaps,
Shelves, Seats, and the like.
WC, ALBERT BARKER, of 5 New Bond Street, Silversmith, and THOMAS HAYDON, of
24 Camden Street, Islington, Cabinet Maker, both in the County of London, 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 had to the accompanying drawings and to the letters and
figures marked thereon, that is to say :-
This invention relates to that class of bracket in which one hand only is necessary
to effect the raising and lowering of the flap to be supported by the bracket proper or
mainstay.
According to our improvements the upper part of the centrally hinged mainstay
is slotted, and through this slot works a short stay which, at its rear end, is hingel to
the under side of the flap to be raised or lowered, and at its fore end terminates in a
finger-piece formed with shoulders.
When this finger-piece is raised, in order to lower the flap, the shoulders, after
a certain amount of travel, strike against the uppermost portion of the centrally
hinged mainstay, and thus cause said mainstay to fold inwards on its hinge, and the
flap to fall at a right angle to the ledge to which it is hinged. The hinge con-
necting the short stay to the underside of the flap is a spring hinge, so that directly
the flap is raised and the finger-piece released, this short stay falls to the lower end of
the slot and thus maintains the mainstay rigid, and the flap in its raised and
horizontal position. When the flap is closed the short stay abuts against the upper
end of the slot.

page_text: In order that our said invention may be readily understood and carried into effect,
we proceed to describe the same with reference to the accompanying drawings,
which shew our invention applied to a writing-flap.
Fig. 1 is a vertical section shewing the flap raised and ready for use; Fig. 2 is also
a vertical section shewing said flap lowered and out of use; Fig. 3 is a face view
shewing the short stay working in the slot formed in the mainstay.
a is the ledge or rail to which is hinged the flap or leaf b. c, c, is the centrally
hinged mainstay one extremity of which is hinged, at d, to the back support A, and
the other extremity, at e, to the flap b. is the short stay which works in the slot g
and terminates in a finger piece f. This short stay is provided with shoulders,
and is connected to the flap & by the spring hinge f³. When the flap is raised, the
short stay falls, by the action of its spring hinge, into the position shown by Fig. 1,
and the shoulder, coming against the mainstay c, supports the parts firmly in
position. is a piece of elastic material on to which the short stay falls when the
bracket is opened, and is employed for deadening noise.
x
:
When the flap is to be lowered it is only necessary to lift the short stay by the
finger-piece and the shoulder f coming against the mainstay and causing it to
fold inwards on its central hinge permits the parts to turn about their hinges and to
assume the position shewn at Fig. 2. i is a stop, fixed to the back support, for
preventing the flap or leaf from falling too far when closed and out of use.
Although we have described and shewn our invention as applied to a writing-flap,
it is obvious that it may be equally well applied to brackets, tables, shelves, seats, and
the like.
Having now particularly described and ascertained the nature of our invention,
and in what manner the same is to be performed, we claim :-
In brackets for writing and other tables, flaps, shelves, seats and the like, the
combination of the spring controlled hinged short stay, having shoulders, and
finger-piece with the hinged mainstay which is slotted to allow of the working
therein of said short stay, substantially as described and shewn, and for the purpose
set forth.
