Improvements in Combined Lights and Ventilators for Ships.
I, THOMAS UTLEY, of Sefton House, Crosby Green, West Derby, Liverpool,
Engineer, do hereby declare the uaturo of this invention to be as follows:-
This invention relates to ships side lights so construoted that by moving the
glass holder to and fro in the frame a ventilation opening of more or loss capacity
according to the adjustment of the holder is provided.
For the purposes of my invention I make the frame, which projects inboard a
suitable distance, larger at the outer end than at the inner end and 1 provide the
glassholder with square or equivalent pivots at top and bottom to slide in
guideways formed in or applied to the frame, or I arrange the glassholder to work
npon screws by which it is moved in and out. The glassholder is constructed as
lieretofore with a bead, or flange, on its inner face to make a tight joint with an
india rubber seating ring arranged in a flange of the frame, and it is furnished with
the usual hinged screw bolts and lugs for securing it tightly in place when
required. By loosening the securing bolts and thou sliding the glassholder
outwardly in its guides, or by means of the screws, an opening is made all round
the holder for the admission of air, such opening increasing in capacity the further
the glassholder is pushed out. So that by adjusting the position of the glass-
holder the air current can be regulated as desired. The extent of outward
movement of the glassholder is limited by suitable stops which may be reinovable
plates arranged to close the ends of the aforesaid guideways.
The glassholder may be rectangular, square or round or of any other desired”
shape.
By reason of the flange which carries the jointing ring standing up above the
level of the lower edge of the glassholder the device is rainproof.
In combination with the aforesaid light I prefer to provide a grid ventilator at
the upper part of the frame above the glassholder said ventilator being adapted to
admit air behind the glassholder when the latter is open and so increase the
ventilation. I provide an inclined shield inside the grating to prevent rain from
beating inboard through the grating.
Dated this 2nd day of April 1897.

COMPLETE SPECIFICATION.
Improvements in Combined Lights and Ventilators for Ships.
I, THOMAS UTLEY, of Sefton House, Crosby Green, West Derby, Liverpool,
Engineer, 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 ships lights so constructed that by moving the

page_text: glassholder to and fro in the frame a ventilation opening of more or less capacity
according to the adjustment of the holder is provided. The said lights are
applicable for deck houses and for ships' sides.
For the purposes of my invention I make the frame, which projects inboard a
suitable distance, larger at the outer end than at the inner end aud I provide the
glassholder with square or equivalent pivots or lugs at top and bottom to slide in
guidoways formed in or applied to the frame, or I arrange the glassholder to work
upon screws by which it is moved in and out. The glassholder is constructed as
heretofore with a bead, or flange, on its inner face to make a tight joint with an
india rubber seating ring arranged in a flango of the frame and is furnished with
the usual hinged screw bolts and lugs for securing it tightly in place when
required. By loosening the securing bolts and then sliding the glassholder
outwardly in its guides or moving it by means of the serows an opening is made
all round the holder for the admission of air, such opening increasing in capacity
the further the glassholder is pushed out. So that by adjusting the position of the
glassholder the air current can be regulated as desired.
In combination with the aforesaid light I sometimes provide a grid ventilator
facing outwards at the upper part of the frame above the glassholder, said
ventilator being adapted to admit air behind the glassholder when the latter is
open and so increase the ventilation.
Referring to the accompanying drawings which illustrate a side light constructed
according to my invention.
Figure 1 is an outside clevation of the light.
Figure 2 is a vertical central section, and
Figure 3 is a horizontal central section of the light; and
Figure 4 is a section of a portion of the light illustrating a modification
hereinafter described.
Like letters of reference deuote corresponding parts in the several figures.
A is the frame of the light which is secured to the ship's side or deck house in
the usual or in any convenient manner. The said frame projects inboard a suitable
distance as indicated in Figures 2 and 3, and the sides of it are taper so that the
inner end is smaller than the outer end. B is the glassholder constructed with
square pivots or lugs B', B' at top and bottom the same being arranged to slide
in guides C, C formed in or secured to tho frame A. The glassholder can thus
slide in and out a suitable distance but cannot turn. D, D are removable plates
which close the ends of the guideways and prevent the glassholder from being
pushed out of its frame. I have shown a rectangular frame and glassholder but
they may be square or oval or of other desired shape. The inner end of the frame
is constructed with an inturned flange A' adapted to receive the usual india-rubber
jointing ring E for making a secure water tight joint with a bead or flange B¹
formed around the edgo of the glassholder. E, E are the hinged bolts for
screwing the glassholder tightly home when it is desired to close the light. These
bolts are constructed and secured in the usual manner.
It will be observed that by reason of the taper formation of the frame A. an
opening for admitting air will be formed around the glassholder when the latter is
pushed back, and the further the glassholder is pushed back the larger will be the
opening thus formed, so that a means is thus afforded of regulating the size of
the ventilation opening by adjusting the position of the glassholder in its frame.
In addition to the opening thus afforded, I prefer to construct the light when
used in a deck house with a vontilation grating E at the top through which air
can pass into a chamber or cavity F whence it passes through holes in the plate G
and enters the vessel when the glassholder is pushed back. In order to prevent
rain, sea water or spray from beating inboard through the gratings when the light
below is open I provide a sloping shield H within the chamber so arranged as
to drain off any rain, sea. water or spray, that may enter through the outer
grating E. The flange A¹ prevents rain, sea water or spray from beating inboard
around the glassholder except when the latter is fully open, In lieu of the

page_text: ventilator above described I sometimes use above the light a trunk ventilator of
the kind described in the Specification of my prior Patent No. 20779 A.D. 1892.
In Figure 4 I have shown a modification according to which the glassholder is
adjusted by sorews K passing through the lugs B' of the glassholder. The said
screws also serve as guides for the glassholder in lien of the guides C.
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 that what I
claim is :-
1. In a ship's light and ventilator the combination of a frame which is smaller
at the inner end than at the outer end, and a glassholder, adjustable to and fro in
said frame, substantially as, and for the purpose, specified.
2. In the said light and ventilator the construction of the glassholder with pivots
or lugs at top and bottom which can slide but cannot turn in guidos, or which are
controlled by screws passed through them, substantially as described.
3. The combination, with the ship's light and ventilator covered by the first
claiming clause, of a trunk ventilator such as that hereinabove referred to or a
grating ventilator and sloping shield, substantially as described, and for the
purposes specified.
4. The combined ship's light and ventilator constructed substantially as described
with reference to Figures 1, 2 and 3 of the accompanying drawings and operating
as, and for the purposes, specified.
