PROVISIONAL SPECIFICATION.
Improvements in Skylights, Ventilators, Sidelights, and the like.
I JOHN MASON 66 Musgrave Street West Hartlepool Joiner do hereby declare
the nature of this invention to be as follows:-
In the specification of Letters Patent granted to me and dated 11th May 1886
(No 6312) for "Improvements in Windows," I therein describe and illustrate several
inethods of applying hinged weathering plates to the Sashes of Windows.
Now this my present invention has for its object the application of the said hinged
weathering plates, but of modified construction, to skylights, ventilators, and for the
like purposes.
In such cases where it is found to be advantagous to construct the said skylights,
ventilators and the like of Cast Iron, Malleable Iron, or other metal, one balf the said
hinged weathering plates may be cast with the solid portion of the frame, and the
other half together with a suitable weathering projection, or bead, to be cast with the
swinging portion of the said sky light or ventilator.
In my previous invention I therein describe and illustrate weathering plates of
rectangular section, the said plates having one or more projections.
I now claim in addition to these, weathering plates of semi-circular or other suit-
able section, either solid or troughed, and which may be plain, or may be provided
with a bead or beads, or a tongue or tongues, of V section, the said bead or beads,
or tongue, or tongues of V section, being on the inside or hollow back of the afore-
said weathering plates.
Although I have referred only to Skylights and Ventilators, it will be understood
that these wenthering plates of whatever kind or section, may be also applied to iron
windows, doors, or other analogous uses.

COMPLETE SPECIFICATION.
Improvements in Skylights, Ventilators, Sidelights, and the like.
I, JOHN MASON, of 66, Musgrave Street, West Hartlepool in the County of
Durham, Joiner, 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 :-
This invention relates to improvements in the arrangement described in the
specification of Letters Patent granted to me on the 11th day of May 1886 and
numbered 6312, for Improvements in windows," and its object is to apply such
improvements to windows having metal frames such as, skylights and sidelights with
malleable iron or other metal frames and flaps used on board ship to light and
ventilate the engine rooms berths etcetera.
The said improvements are applicable to that class of ships lights and the like in
which the flap is pivoted approximately at the centre to each side of the frame and
consist of the arrangement or device herein after described whereby a water-tight
joint is formed between the flap and the frame when the flap is closed.
In order to fully describe my invention reference is to be had to the accompanying
sheet of drawings in which similar letters of reference indicate corresponding parts
in each of the figures.
Figures 1 and 2 represent a skylight in elevation and vertical section to which my
improvements are applied and figure 3 is an elevation showing the same open.

page_text: Figure 4 is an elevation of a sidelight illustrating the application of my improve-
ments. Figure 5 is a similar view of the frame of the latter with the flap omitted.
Figure 6 is a section on a larger scale of said frame and a portion of the flap.
I preferably construct the outer frame A of malleable or wrought iron and secure
it by rivets by means of the bolt holes B in the flange C in the usual manner.
The said frame is provided with hinge knuckles D and D¹ at each end of a pro-
jecting bead E formed round one half of A and such head is provided with a
groove or recess F extending from the centre of knuckle D round the frame to
the centre of D₁ and filled with india rubber or other suitable packing I. A
similar groove F1 also filled with packing extends along the other side and face
of the frame from the centre of knuckle D and D¹. The flap G is also provided
with hinge knuckles H and H₁ pivoted to D and D' by the bolts J and such flap
has Vee section weather bars K formed round the edges next to the grooves F and F¹
which when the flap is closed inbed themselves in the packing 1 and thus form a
perfectly tight joint all round.
The frames A are provided with eyebolts L and wing nuts M engaging claws N on
the Hap by which they are secured in the closed position, and a quadrant arm O pivoted
to the flap and provided with suitable stops may be used to hold the flap more or less
open.
It will readily be seen that by the arrangement herein described a perfect joint is
formed between the flap and the frame thus enabling the convenient method of
mounting the flap illustrated in the drawings to be generally used, which hitherto
has not been practicable owing to the difficulty in providing a tight joint.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare what I
claim is:
:
The construction of ships lights or the like, having the flap pivoted at both sides
as herein illustrated, with Vee shaped weather bars arranged in contact with grooves
containing suitable packing, substantially as herein shown and described and for the
purpose specified.
Dated this 29th day of June 1889.
