An Improved Self-acting Stay or Prop for Supporting Hinged Lids,
Flaps, Covers, and other Hinged Parts of Desks, Show-cases,
Trunks, and other Box-like Articles, and for Supporting Roof
and Deck Lights Opening in the same manner as a Hinged Lid.
I, THOMAS MONTEATH, of 76 Burrell Street, Crieff, in the County of Perth, Joiner,
do hereby declare the nature of my said invention for "AN IMPROVED SELF-ACTING
STAY OR PROP FOR SUPPORTING HINGED LIDS, FLAPS, COVERS, AND OTHER HINGED
PARTS OF DESKS, SHOW-CASES, TRUNKS, AND OTHER BON-LIKE ARTICLES, AND FOR
SUPPORTING ROOF AND DECK LIGHTS OPENING IN THE SAME MANNER AS A HINGED LID,"
to be as follows:-
I joint a curved lever or arm A to one or both sides of the desk, trunk, box or
other article pivoted on a stud or centre, or simply fastened with a screw B at the end,
and I provide this arm at the other end with a friction pulley C which is intended to
run on the spring D which brings the arm into position when supporting the lid or
flap E. One end of this spring is fixed to the lid or flap at a point suitable to the
required pitch by means of two screw-nails passing through a slot F by which the
balance of the lid can be regulated. The free end of this spring is bent at a suitable
angle and is forked so the curved arm passes between. The forks are connected at
their extremities by a pin on which revolves a friction pulley or roller G or it may
simply have a rounded pin which bears against the under edge of the curved arm.
The arm with its friction pulley at the end, in passing through the slot so formed, is
directly guided to its bearing on the spring, the spring thereby giving protection to
the lid or flap.
The automatic action may be given to the arm by a coil spring fixed at the pivot
but in this case the spring will be on tension when the lid is shut.
This stay or prop is specially applicable for the support of roof and deck lights
when these are made with wooden frames.

Flaps, Covers, and other Hinged Parts of Desks, Show-cases,
Trunks, and other Box like Articles, and for Supporting Roof
and Deck Lights Opening in the same manner as a Hinged Lid.
I, THOMAS MONTEATH of 76 Burrell Street Crieff, in the county of Perth, Joiner
do hereby declare the nature of my invention for AN IMPROVED SELF-ACTING STAY as
entitled above and in what manner the same is to be performed, be particularly
described and ascertained in and by the following statement:-
I joint a curved lever or arm A to one or both sides of trunk box or other article,
pivoted on a stud or centre or simply fastened with a screw at the end B, and I
provide this arm at the other end with a friction pulley C which is intended to run
on the spring D which brings the arm into position when supporting the lid or
flap E.
One end of this spring is fixed to the lid or flap at a point suitable to the required
pitch by means of two screw nails passing through a slot F by which the balance of
the lid can be regulated.
The free end of this spring is bent at a suitable angle and is forked so that the
curved arın passes between. The forks are connected at their extremities by a pin on
which revolves a friction pulley G or roller, or it may simply have a rounded pin
which bears against the under edge of the curved arm A. The arm with its friction
pulley Cat the end in passing through the slot so formed is directly guided to its
bearing on the spring, the spring thereby giving protection to the lid, flap or other
surface to which it is fastened.
The automatic action may be given to the arm by a coil spring fixed at the pivot
but in this case the spring will be on tension when the lid is shut.
This stay or prop may be applied for the support of roof and deck lights when these
are made with wooden frames.
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,
The use and manufacture of Automatic stays made of iron, brass, or other material,
for supporting the lids of desks and other hinged covers and having a spring
arrangement as hereinbefore described and any modification thereof.
The features of novelty claimed are
1st. Automatic action.
2. Simplicity.
3 Cheapness.
