PROVISIONAL SPECIFICATION.
A Hinged Stay for Supporting the Flaps of Tables, Brackets,
or similar articles.
I, JOHN THOMAS MARSHALL Junr. of 28 Hoxton Square London N. Cabinet.
Maker do hereby declare the nature of this invention to be as follows:-
My invention consists of two strips of metal or other material "A" "C" of any
length may desire, hinged together; and a stop B of any metal or material
forming a guide through which the strip A may run; upon the top of the stop B I
fix my rivets or otherwise a spring D of any shape or material most convenient.
The strip C is fixed by means of screws or any other method suitable to the
frame F the hinge end uppermost.
.:
The stop B is fixed to the flap E by similar means in such a position that when
the flap E is raised to the position the stay is required to hold it in the point of
the strip A shall just touch the edge of the stop B at its bottom edge G Fig. 2
and the spring" D at its free end shall press the strip A steadily against the
flap E Fig. 1.
It will now be seen that the pressure of the spring D upon the strip A will keep
the point of the strip A close up to the stop B and thus holding the flap E firmly
in the position desired, and that by relieving the pressure with the fingers of the
spring D upon the strip A, the strip A will enter the groove in the stop B and the
flap E will fall into position E.
To raise the flap E¹ again into its first position E it is only necessary to raise it.
with the hand to position required the hinged stay fixing it automatically.

COMPLETE SPECIFICATION.
A Hinged Stay for Supporting the Flaps of Tables, Brackets,
or similar articles.
I, JOHN THOMAS MARSHALL Junr. of 28 Hoxton Square London N. Cabinet
Maker 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 :-
My invention consists of two strips of metal or other material A, C, either flat or
any other shape most suitable and of any length or width I may desire (as per
drawing left with the Provisional Specification) hinged together; and a stop B of
any metal or other material through which is an hole just large enough to allow of
the strip A running freely through it. On the top of the stop B I fix by rivets or
other means a spring D of any shape or material most suitable.
The strip C is then fixed to the frame F by screws or other means the jointed
end uppermost; and the stop B by similar means to the flap E that has to be.
supported, in such positions that when the flap E is in the position in which it is
required to be held the point of the strip A shall just touch the edge of the stop B
at the angle formed by the edge of the stop against the under side of the flap E
with the free end of the spring Ď pressing against the under side of the strip A the
jointed end of the strip A being fixed at any degree lower than the other end
most convenient.
It will now be seen that when the flap E is raised to the position in which it is
to be held (Fig. 1) the point of the strip A is firmly held (by the pressure of the

page_text: spring D) in the angle formed by the stop B against the under side of the flap E,
so that it is impossible from the upper side of the flap E to force down to position E 1
the said flap either by weight or pressure.
To lower the flap E to position E 1 it is only necessary to relieve the pressure
of the spring D upon the strip A with the fingers the point of the strip A will then
enter the hole in the stop B and the flap will fall into position E 1.
In order to fix the flap again into position E it is only mecessary to raise it into
position, the hinged stay fixing itself automatically.
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 if
claim is
1. In a hinged stay applicable to the flaps of tables, brackets or similar articles
the combination of a hinged stay A. C, stop B and spring D acting substantially
as described & illustrated..
