Improvements in Apparatus for Employment in Opening and Closing
Fanlights and Skylights, and Retaining them in any Desired
Position.
I, ARTHUR ILLIDGE, of 16 Church Street, Wolverhampton in the County of
Stafford, brassfounder, do hereby declare the nature of this invention to be as
follows:-
This invention consists in certain combinations or arrangements of mechanism
constituting apparatus for employment for the purposes stated in the title.
I will describe this invention specially with reference to falights, for which it
is more particularly intended, when its application to skylights will be sufficiently
obvious.
According to one modification of this invention, for employment in the case of
a fanlight which opens inwards at the top, a spring catch or latch is fixed to
the fanlight and a stay bar is connected with the frame and passes forwards
through a guide or bridle formed on or fixed to the top of the catch or latch
case. A cord or chain is connected at its upper end to a part of the bolt of the
catch or latch, or to a part which when drawn down draws down also such bolt,
and passes down from thence sufficiently to be taken hold of by a person in the
гоот. A number of holes, indentations, or notches are formed in the bar int
any one of which the bolt projects when opposite thereto and free to be moved
up by the spring. To open the fanlight, the cord is pulled downwards to draw
the bolt out of gear with the bar, and also inwards to draw the fanlight open to
any desired extent; and upon the release of the cord the bolt. is again pressed
upwards by its spring and, if opposite thereto, enters one of the holes, indentations,
or notches therein and thus securely retains the fanlight in an open or partially
open position, as desired; or, if the bolt is not immediately opposite one of such
holes, indentations, or notches, it bears against the bar and holds by friction, or
if the fanlight is moved inwards or outwards, by the wind or otherwise, whilst
the bolt is free to be pressed up by the spring, the bolt enters the hole, indenta-
tion, or notch to which it first comes opposite during such movement of the
fanlight. A second cord or chain is connected with the frame and passes over a
pulley carried by the fanlight. The fanlight may be closed by first pulling down
the bolt in the manner above described and then, while it is held down, pulling the
second cord. The catch is then released to fasten the fanlight in its closed position.
The second cord may be used also as a check or drag to prevent the fanlight being
opened too wide as it is pulled open by the first cord. The vibration of the stay
bar may be allowed for by hinging it to the frame, or by forming it of such
shape and material as will allow it to spring sufficiently, for instance as a flat steel
bar.
An important feature of this invention consists in means whereby the stay bar is
turned on one side as the fanlight is closed in. For this purpose the bar may be
curved in shape sideways and be pivotted at its connected end so as to allow it to
turn sideways. In such case it is curved to one side when the fanlight is closed, but
As the
its outer end is drawn forwards as the guide aforesaid slides along the bar.
fanlight is again closed the bar is again turned to one side by the action of the guide
sliding therealong. According to another method, the bar is formed straight and is
pivotted to a bracket which is fixed to the fanlight and which projects sufficiently
forwards through the guide, aforesaid, when the fanlight is closed to allow of the bar
being turned sideways parallel with the plane of the frame; the bar is provided with a
toe-piece or stud on one side at its pivotted end, and when the fanlight is open or

page_text: partially so the bar projects directly forwards, but as the fanlight closes a part carried
thereby pushes against the toe-piece or stud and turns the bar sideways parallel with
the plane of the frame. As the fanlight is opened it is drawn from off the bracket
and slides along the bar. By turning the bar sideways as described the unsightliness
of a bar projecting forwards when the fanlight is closed is avoided, and such an
arrangement permits also of the employment of a blind in front of the fanlight.
The apparatus above described may be applied to a fanlight which opens outwards,
but in such case the catch is fixed to the frame and the bar is connected with the
fanlight, and the fanlight may be drawn in close and moved outwards by any suitable
means now employed for such purpose. When the arrangement of curved stay bar is
employed, cords passing around suitable pulleys and connected with the unconnected
end of such bar may be used for opening and closing the fanlight.
A modification of this invention consists in forming teeth on the stay-bar, above
described as being capable of turning sideways and of being operated to turn in such
direction as the fanlight is closed, and gearing a worm, operated by an endless cord,
therewith (either directly or through the medium of a spur wheel) in lieu of the bolt
above described. In this case the fanlight is not only held in any desired position by
the worm but is also opened and closed thereby.
The application of this invention to skylights will now be sufficiently obvious with-
out need for further detailed description.

Improvements in Apparatus for Employment in Opening and Closing
Fanlights and Skylights, and Retaining them in any Desired
Position.
I, ARTHUR ILLIDGE, of 16 Church Street, Wolverhampton in the County of
Stafford, brassfounder, 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 has for its object certain combinations or arrangements of mechanism
constituting apparatus for employment for the purposes stated in the title.
A modification of the apparatus employed according to this invention, in the case
of a fanlight which opens inwards at the top, is illustrated by figures 1, 2 and 3 of
the drawings herewith, of which figure 1 is a vertical section through the upper end
of the fanlight A and frame B and through the apparatus; figure 2 is a front or
inside view of figure 1, but with the fanlight shewn in its closed position and with the
stay-bar C shewn in section; and figure 3 is a view of the catch mechanism as seen
from the side thereof which is towards the fanlight when fixed in place thereto. The
stay-bar is, preferably, formed as a flat steel bar which will allow of some degree of
elasticity, and is connected with the upper portion of the frame by means of a pin or
rivet a around which it fits somewhat easily so that it may be capable of some degree
of vertical movement. This bar, however, may be rigidly fixed to the frame, if
desired, and be formed of a shape struck to a true curve from the hinge of the fanlight
as a centre so that it has no need to be moved vertically; or it may, when formed as
a flat steel bar, be fixed rigidly to the frame in which case, if not curved concen-
trically with the hinge, it yields elastically as the fanlight is moved. It is preferred,
however, to curve the bar somewhat longitudinally, as shewn, even when made of flat
steel as described.. Catch mechanism carried within a case D is fixed to the upper
portion of the fanlight, as shewn, and a guide or bridle & is formed with and over the
top of such case, and the bar C passes through such guide and is thereby guided, and
retained in proper position, in relation to the fanlight. Holes e are formed through
the bar (or notches or recesses may be formed in its underside if the bar is of
sufficient thickness to admit thereof, or teeth with suitable spaces between may be

page_text: employed) and a catch d is pressed up by springs e e through the top of the case D
and into any hole c to which it may come opposite, and thus the fanlight A is securely
held in any desired position. The catch d may be drawn down clear of the bar, so
as to allow of the movement of the fanlight, by means of a short lever pivoted
within the case and bearing upon a short bar y which joins two sides of the
part of the catch within the case. The lever passes from its pivoted connection,
through an opening above the bar g and between the sides formed through the
part of the catch which is within the case, out through a slotted opening in the
front of the case. This lever is drawn down by means of a cord i. A bracket j
is formed with or fixed to the case D, or is otherwise fixed to the upper portion
of the fanlight, and a pulley k is mounted therein, and a cord which is fastened
at one end to the upper portion of the frame B passes over such pulley and
downwards into a position where it may be taken hold of by the operator. This
cord is for the purpose of closing the fanlight, when desired, and of preventing
it from being opened too suddenly. A guard m is carried over the top of the
pulley to prevent the cord slipping off. o is a stop on the outer end of the
bar ( to prevent the fanlight from being opened too far.
The action of the apparatus is as follows:-
Assuming the parts to be in the position shewn by figure 1, if it is desired to close
the fanlight the cord is pulled down until the catch d is drawn clear of the hole
through which it passes in the bar C, the cord being at the same time pulled down
firmly so as to prevent the fanlight being opened further as the catch is drawn out of
the hole in the bar, and the cord is pulled down tightly while the catch is held out
of the bar, and thus the pulley and consequently the fanlight are moved inwards
towards the frame and the fanlight thereby closed. The fanlight is held in its
closed. position by releasing the cord, whereupon the catch dis shot up by the
springs into the hole c in the bar C which is the nearest to the franie. When it
is desired to open the fanlight the cord is held down with sufficient tension to
prevent the fanlight being opened too suddenly, while the cord is pulled down-
wards to draw the catch out of the hole in the bar and also forwards or inwards
so as to draw the fanlight open while the catch is held down. If on the release
of the cord the catch is not immediately opposite one of the holes c in the bar
it bears against the bar and holds by friction, or if the fanlight is moved inwards
or outwards by the wind or otherwise, whilst the catch is free to be pressed up by
the springs, the catch enters the hole c to which it first comes opposite during such
movement of the fanlight and then securely holds the fanlight in position.
A modification of this invention in which a portion of the stay-bar is hinged to fall
down parallel, or approximately so, with the face of the fanlight in order that a blind
may be used when the fanlight is closed (and to avoid the unsightliness of the bar
projecting forwards into the room when the fanlight is closed), is illustrated by
figure which is a view corresponding to figure 1 but shews the fanlight closed. In
this case a short length of the bar is rigidly fixed to the frame 13 (or it may be
pivoted thereto similarly as the bar C previously described, or otherwise hinged or
pivoted thereto, if desired) and the outer end of the bar is hinged to the forward
end of the part C, as shewn, so that it may fall down into the position shewn when
the fanlight is closed. As the fanlight is drawn open the upper portion of the case D
bears against the underside of the part of the bar and raises it into position to
allow the guide to pass therealong as the fanlight is further opened. In this
modification the cord for pulling down the catch and pulling open the fanlight is
shewn to be fixed to a ring on the bottom thereof, the bottom of the catch passing out
ibrough the bottom of the case D, and the catch is shewn to be pressed up by means
of a spiral spring e around the shank thereof bearing against a shoulder under the
head. This arrangement of catch and spring and means of operating it may be
employed also in the case of the modification previously described, and the corre-
sponding means described with reference to the former modification may be adopted in
this case.
n is a stop projecting forwards from the case D to prevent the part
the bar swinging in against the fanlight.
of

page_text: An important feature of this invention consists in means whereby the stay bar is
turned to one side as the fanlight is closed in so as to admit (as in the modification
last described) of a blind being used when the fanlight is closed (and to avoid the
unsightliness of the bar projecting forwards into the room when the fanlight is closed).
A modification of this part of the invention is illustrated by figures 5, 6 and.7, of
which figure is a front view shewing the fanlight closed, and corresponds to figure 2,
and shews the bar turned sideways so as to leave room for a blind in front of the
fanlight figure 6 is a plan of figure 5; and figure 7 is also a plan of figure 5, but
shews the fanlight to be some distance open. The stay bar C is formed to the shape
shewn, and is pivoted at p within a mounting 7 let into the frame B, otherwise
the construction and operation of the apparatus is substantially the same as that
illustrated by figures 1, 2 and 3. The method of operating the catch, however, is
shown to be the same as illustrated by figure 4, hut it may of course be the same as
shewn by figures 1, 2 and 3. When the catch is drawn down by the cord i and the
fanlight drawn forwards in opening it, the side of the guide through which the bar
passes, bearing against the inner edge of the bar moves the bar forwards into the
position shewn by figure 7 so that the catch may engage with the other holes formed
therethrough. One of the holes, namely the hole r, is shewn on the curved or
slanting portion of the bar, and this hole comes opposite to the catch as the bar is
being turned into position during the movement of the fanlight, and in the same
manner any holes along the bar may be brought into position over the catch. The
opening through the guide is shaped in plan as shewn by broken lines figure 6, and
the bar is moved and guided by the sides of such opening, as will be readily under-
stood. A long slotted hole s formed in the mounting to receive the pivoted end
of the bar when in the position shewn by figure 7.
.
A further modification of the part of this invention in which the stay-bar is turned
to one side as the fanlight is closed is illustrated by figures 8 and 9, of which figure 8
is a plan with the fanlight closed; and figure 9 a plan with the fanlight partly open.
A short length C of the bar is formed as a jaw to receive the outer portion C', which
is pivoted thereto at p so as to be capable of being turned sideways, and the part C is
fixed to the upper portion of the frame. The catch mechanism and the arrangement of
cord and pulley closing the fanlight are of the character as in the other modifications,
and the fanlight is operated in the same manner. When the fanlight is closed the
part C of the bar projects through the guide & formed at the top of the case D. The
inner or pivoted end of the part C¹ of the bar is formed with a toe-piece which,
when the bar is in the position turned to one side shewn by figure 8, bears against
the inside of the guide and prevents the bar from being pulled outwards. As the
fanlight is drawn open the forward edge of the side of the guide hears against the
inner edge of the bar and draws the bar forwards until it is in the forward position
shewn by figure 9; and as the fanlight is closed in the side of the guide presses
against the toe-piece t and moves the bar back again into the position shewn by
figure 8. The bar is hollowed in, as shown at t¹, to allow clearance around the forward
edge of the guide when the bar is turned, sideways into the position shewn by
figure 8.
The apparatus described in the last preceding paragraph, and illustrated by
figures 8 and 9, may be modified as shewn by figures 10 and 11, of which figure 10
is a plan corresponding to figure 8, and figure 11 a side view of figure 10 looking in
the direction of the arrow 2. In this modification, in lieu of forming a toe-piece on
the part of the stay-bar, a stud t projects from the underside of the bar in the
position shewn, and an L-shaped lug formed out from the catch case D catches
against such stud as the fanlight is closed in and so turns the bar into the position
shewn by figure 10. The bar is turned forwards in opening the fanlight as in the
case of the modification last described.. A shallow recess is formed in the top edge of
the case D to allow the stud to clear through it as the case is drawn forwards along
the bar.
A modification of the apparatus described with reference to figures 5, 6 and
7 is shown by figures 12 and 13, of which figure 12 is a side elevation shewing the

page_text: fanlight closed, and figure 13 an inside or front view of figure 12. In this case the
curved bar C is pivoted to hang down, as shewn, when the fanlight is closed, and
the catch case is fixed to the fanlight so that the catch head will shoot, sideways
into the bar, and the catch head is drawn back clear of the bar by means of a
cord operating through the medium of a lever f; otherwise the apparatus is the
same in construction and operation as that described with reference to figures 5, 6
and 7. The means by which the lever operates to draw back the catch head will be
readily understood on perusal of the description of the modification illustrated by
figures 14, 15, 16 and 17. In that case however the lever is towards the opposite
hand and is pulled upwards to draw back the catch head instead of downwards as in
this modification.
The modifications described with reference to figures 8, 9, 10 and 11 may also be
adapted to operate so that the pivoted or outer portions of the stay-bars hang down
when the fanlight is closed. This adaptation will be readily understood without need
for illustration or detailed description, as it is substantially the same as the adaptation
described in the last preceding paragraph of the modification shewn by figures 5, 6
and 7.
A modification of this invention for employment with a fanlight opening outwards
at the bottom is illustrated by figures 14, 15, 16 and 17, of which figure 14 is a
vertical section through a portion of the fanlight and frame and shews the apparatus
for operating it in side elevation, the fanlight being partially open; figure 15 is a
corresponding view to figure 14 but shews the fanlight closed; figure 16 is an
elevation looking in the direction of the arrow y, figure 14; and figure 17 is a
detached view of the catch case, with a portion of the front shewn as broken away to
expose the interior mechanism. In this modification the catch case D is fixed,
preferably, to the side of the frame, but it may of course be fixed to the bottom, and
the stay bar C, which is preferably curved in shape lengthways, as shewn, is pivoted
to a mounting carried by the fanlight. In this case the bar passes through a guide b
formed on one side of the catch case D, and the catch d is in a horizontal position so
as to enter sideways into the holes c in the bar. Upon a stud projecting sideways
from the forward or unconnected end of the bar C is mounted a cord pulley a', and
a cord i passes over the top of such pulley and is connected to a lever which
when drawn up by the cord causes a short follower b' on the same axis to bear against
a lug on the tail of the catch and draw it back against the pressure of a spring e,
and thus draw the catch d clear of the bar C. A guard m on the end of the bar C,
passes partially around the pulley a¹ to prevent the cord i slipping off.
passed over a pulley mounted in a bracket which is formed with or
case D, or which may be otherwise fixed to the frame B, and this cord is fastened, as
shewn, to the fanlight.
A cord is
fixed to the
To close the fanlight both the cords i and I are drawn down so that the cord i shall
pull up the outer end of the lever and draw back the catch d clear of the bar C, and
the cord prevent the tension of the cord i from moving back the bar (and thus
opening the fanlight A still further. While sufficient tension is maintained on the
cord to hold the catch clear of the bar, the fanlight is closed in by continuing to
pull at the cord 1. The fanlight is opened entirely by means of the cord i, which
when pulled down first draws the catch clear of the bar and then moves the bar
outwards. In this latter operation, however, it is desirable to maintain some tension
on the cord in order to prevent the fanlight being opened too suddenly.
In this modification the stay bar may be pivoted to the fanlight as shewn, and the
case D with the guide for the bar may be fixed at such height, as shewn, in relation
to the pivot of the bar, that as the fanlight is closed in the har will be turned up so
as to project a short distance only into the room as shewn by figure 15, and thus
allow a blind to be used therewith. For this purpose sufficient space is left in the
upper side of the guide through which the bar passes. The bar may, however,
be fixed rigidly to the fanlight, if desired, in which case its curve is concentric with
the hinge.
This modification may be used also for a skylight, and in such case the cord 7. may

page_text: be dispensed with as the weight of the skylight will cause it to close when only
sufficient tension has been put upon the cord to draw the catch clear of the bar. If
the cord is used, however, it will enable the operator to ensure the tight closing of
the skylight in case it should stick or bind in its frame and prevent its own weight
from closing it properly.
This invention also comprises modifications in which the stay bars described
with reference to the apparatus shewn by figures 5, 6 and 7, figures 12 and 13,
and figures 14 and 16 (and whether the latter is used for a fanlight or skylight)
are provided with teeth into which gear a worm, operated by an endless cord, either
directly or through the medium of suitable gear.
This part of the invention is shewn in plan as applied to the stay-bar Cof
figures 5, 6 and 7, by figure 18. Sufficient only of this modification is shewn to
make it clear when taken in conjunction with the description thereof and with what
has gone before. The bar, and also the teeth which are formed on the underside
thereof, are shewn by broken lines. Within the case D, which corresponds to the
cases similarly lettered in tho other modifications, is carried a worm e which gears
into the teeth f. The worm is operated by means of an endless cord passing around
a pulley d mounted on the axis of the worm. This pulley should be provided with
teeth, as shewn, to give a firm grip on the cord, and it is convenient to employ a
pulley, recently come into use for this class of apparatus, in which the teeth on one
side of the groove slant in an opposite direction to those on the other side. Figure 19
shews an inside view of one half of the pulley with the teeth thereon, the teeth of the
opposite half being shown by broken lines. The top of the case is provided with a
proper guide or bridle (not shewn on the plan, figure 1S) to act as a guide to the bar
as in the modification shewn by figures 5, 6 and 7. The teeth are shaped and are
used in such position on the bar as to follow one another properly into the spiral of
the worm as the bar turns forwards. The catch and cords used in the other modifica-
tions are of course dispensed with.
The application of this part of the invention to the stay-bars C of the modifications
shewn by figures 12 and 13 and figures 14 and 16 will now be obvious, without need
for special illustration. The teeth are formed on the side of the bars and the worm
is carried in a case fixed on the side of the frame (or it may be at the top or bottom
thereof as the case may be) in lieu of the catch shewn.
When a worm is employed as described it not only operates to open and close the
fanlight or skylight, but acts also to retain it in any desired position.
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 1
claim is :-
