Hinged Parts of Desks, Trunks, and other Box-like Articles.
I, THOMAS MONTEATH of Comrie Road, Crieff, in the County of Perth, Joiner,
do hereby declare the nature of my said Invention for "A. SELF-ACTING STAY
FOR HINGED LIDS, FLAPS, COVERS, AND OTHER HINGED PARTS OF DESKS, TRUNKS,
AND OTHER BOX-LIKE ARTICLES," to be as follows:-
To one or both sides of the desk, trunk, box, or other article, and a little distance
from the front, where the lid or flap opens, I joint a double armned lever pivoted on
a stud or centre. I provide its longer arm at the end with a friction pulley which
is intended to work against the under or inner side of the lid cover or flap, and
I cause the under side of its shorter arm to work against an adjustable stop which
suitably consists of a disc mounted eccentrically on a screw stud in the side of the
desk, and can be secured by such screw. A little distance from the outer end of
the longer arm I connect there to a spring which may be an india-rubber bar spring
or loop spring, the other end of which is connected to the underside of the lid,
cover, or flap, at a point intermediate between the hinge end and the opposite end
of such flap. As the lid is opened, the spring pulls the lever with it, the friction
pulley running against the inner side of lid till the short arm of the lever comes in
contact with the stop, thus forming a self-acting stay or support for the lid.
The eccentric disc stop affords as stated the necessary means for adjustment, both
in the first instance, and in case the spring should become slack by stretching.
The spring is so adjusted that it has its greatest tension when keeping the lid up,
and is slack when the lid is down. The same kind of self-acting stay may also be
applied between an upper and lower division of a box, such divisions being hinged
together.
The spring stay may be jointed at or near the centre, in which case the ends
may be attached, the one to the side of the box, and the other to the lid.

I do hereby declare the nature of my invention for A SELF ACTING STAY FOR HINGED
LIDS, FLAPS, COVERS AND OTHER HINGED PARTS OF DESKS, TRUNKS AND OTHER
BOX LIKE ARTICLES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:—
To one or both sides of the desk, trunk box or other article and a little distance
from the front where the lid or flap opens I joint a double armed or forked lever A
which may be made of Wood, Brass, Iron or their equivalents pivoted on a stud or
centre B I provide this arın at the forked end with a friction pulley C which
pulley may be made of Wood, Iron, Brass or their equivalents which is intended
to work against the inner or under side of the lid, flap or cover, and I cause the
upper side of this arm to work against an adjustable stop D which suitably consists
of a plate E with its upper edge folded over which forms the stop in the side of
the desk and to which the lever is attached by means of a stud, or may be simply
fastened with a screw. I provide this plate with two slots for the purpose of
adjustment. A little distance from the outer end of the arm I connect thereto a
spring F spiral or otherwise which may be an india-rubber, bar spring or loop
spring or may be made of Brass, Steel or their equivalents the other end of which
is connected to the under side of the lid, flap or cover at a point intermediate
between the hinged end and the opposite end of such flap. As the lid is opened
the spring pulls the lever with it, the friction pulley running against the inner
side of the lid till the arm of the lever comes in contact with the stop thus forming
a self acting stay or support for the lid. The plate E on the side of the desk,
trunk, or other box like article affords as stated, the necessary means for adjust-
ment, and in case the spring F should become slack by stretching. The spring F
is so adjusted that it has its greatest tension when keeping the lid up, and is slack
when the lid is down The same kind of self acting stay may also be applied
between an upper and lower division of a box, such divisions being hinged
together.
The spring stay may be jointed at or near the contre, in which case the ends
may be attached the one to the side of the box, and the other to the lid and the
spring fixed at the joint.
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
1st Simplicity.
2nd Automatic.
