Improvements in the Construction of Fanlight Openers, and of
Joints, Links, Handles, Rods, and other Fittings for Com-
municating Power and Motion, Angularly or otherwise, to the
Controlling or other Gear of Fanlights, Swing Windows, Doors,
and Analogous Articles.
I, ROBERT ADAMB of 67 Newington Causeway in the County of Surrey, Engineer
do hereby declare the nature of my said invention to be as follows:
Whereas many of the details and minor parts of apparatas used in connection with
my improved patented fittings described in Nos. 1,3057 4,25983 16,$1784 8,76586
16,6107 and 5,783 and other fittings, as applied to fanlights, swing windows, doors,
and analogous articles, are frequently fixed in situations, which would be more or less
inaccessible or inconvenient, if fitted with appliances as originally constructed, and
such appliances accordingly require modifications and additions thereto to suit them
to such circumstances, and the object. of my present invention is to meet such require-
ments, by means of simple adaptations of and additions to such mechanisms.
For
In modifying my ratchet stay I place the ratchet in bracket guidos, and fit the
same with a spring, so as to cause a tooth, or two or more teeth to engage the bracket
or brackets, the connecting link on the fanlight being jointed to the ratchet.
heavy fan lights it is advantageous to fit a ratchet and connecting link on each side of
the sash, so as to sustain the same equally on both sides and prevent torsional
strain.
In fitting my patent screw fanlight regulators, I sometimes enclose the screw in a
tube or tabes, or its or their équivalent fitted both above and below the regulator, or
otherwise, for the purpose of screening the screw from view, and rendering the device
more sightly, and whereby curtains and other articles are prevented from being
entangled therein or soiled.
When fanlights or the like or the screw or other regulators are placed in inaccessible
or inconvenient positions, I fit or make use of various kinds of permanent or movable
connecting rods, for the purpose of actuating the same from à distance. Such rods
usually require to be rotated on their own centres or otherwise manipulated and to
communicate such rotation or other motion to or from the screwed rod or other
regulator. When a rigid connecting rod is admissible for the purpose, I unite the
same by means of an universal joint or joints, which may be permanent or detachable.
The rigid rod may thus be temporarily moved away from its normal position, rotated
by band or otherwise, and returned to such original position. Or it may per-
manently fixed either in line or out of line with the screwed rod or other regulator,
and operated in any convenient manner, the essence of this arrangement consisting in
the rod, capable of being used at various angles, or in line with the rod, fanlight or
regulator to be manipulated, and the universal joint connecting the same.
be
Various kinds of universal joints may be used, some approximating to the form of
gimbals, and others consisting of square sockets into which a small ball having a
square equator may be caused to enter and rotate the same, and any other convenient
form of universal joint may be applied.
The lower end of the rod may be made square or of any other suitable form to
receive a movable crank, or it may be fitted with an ordinary crank, or a hinged
crank or arm may be fitted thereto, and any other perinanent ineans may be adopted
for imparting a rotary motion to the same:
In some cases I make use of a flexible shaft of any convenient form or material for,
coininunicating rotary motion to the screw rod or other regulator; such flexible shaft
being sometimes enclosed in a tube, or otherwise mounted, and arranged to assume or
approximate to the contour of the structure by which it is supported.

page_text: I sometimes, for the same purpose and in a somewhat similar manner, fit a chain,
composed of metal links suitably made to keep the chain in a central position in a tube
or its equivalent, to enable the shaft to rotate easily. The links of this chain are so
joined together that, on rotating the outer end, the whole chain is caused to rotate and
communicate its motion to the regulator or other object requiring manipulation.
When it is desirable to reduce the length of the screwed rod sfitted to folding stays
as illustrated in Fig. 16 of No. 16,817 and Fig. 6 of No. 16,610 and the various
modificatious thereof in those and other patents or other contrivances having the same
object, I arrange the same so that the rod is actuated by one of the aforesaid methods,
whereby the travelling nut upon the rod is raised and lowered as desired, the con-
necting rods actuating the fanlight in the usual manner.
The several arrangements above described are interchangeable, whenever practicable
and desirable.

COMPLETE SPECIFICATION.
Improvements in the Construction of Fanlight Openers, and of
Joints, Links, Handles, Rods, and other Fittings for Com-
municating Power and Motion, Angularly or otherwise, to the
Controlling or other Gear of Fanlights, Swing Windows, Doors,
and Analogous Articles.
I ROBERT ADAMS of 67 Newington Causeway, in the County of Surrey, Engineer,
do hereby declare the nature of my said invention and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the following
statement
Whereas many of the details and minor parts of apparatus used in connection with
my improved patented fittings described in Nos. 130577, 4259*3, 16,817, 8765",
16,6107 and 5783", and other fittings, as applied to fanlights, swing windows, doors,
and analogous articles, are frequently fixed in situations which would be more or less
inaccessible or inconvenient, if fitted with appliances as originally constructed; and
such appliances accordingly require modifications and additions thereto to suit them to
such circumstances; and the object of my present invention is to meet such require-
ments by means of simple adaptations of and additions to such mechanisms.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
In modifying my ratchet stays described in Nos. 16,817, 8765, and 16,61087, I
sometimes place the ratchet in bracket guides, as shown in Figs. 1, 2, and 3.
Fig. 1 showing the fanlight a hinged at the bottom and opening inwards to the
apartment;
Fig. 2 showing the faulight a hinged at the top and opening inwards; and
Fig. 3 showing the fanlight hinged at the top and opening outwards.
In these figures bis the ratchet, which slides in the slots of the fixed brackets c c.
d (Figs. 1 and 3) is a spring which presses the ratchet b outwards, and thus engages
the bracket. When opening or closing the fanlight, the ratchet bis pushed backwards
so as to overcome the spring and disengage the teeth of the ratchet. e is the
counecting rod to the bracket f.
In the arrangement shown in Fig. 3 a power arm e' is required, as described in my
former specifications above recited, or some of them: In the arrangement shown in
Fig. 2 the spring d may not be required.
Another form of the ratchet bar b is shown in Figs. 4, 5 and 6. Fig. 4 being a
side view: Fig. 6 a front view; and Fig. 5 a plan of the bracket. The bar b may be
of circular or other section. Snugs or projections b' of any suitable shape are formed

page_text: thereon, at suitable distances apart, which rest upon the bracket c, when in the
position shown in figs. 4 and 6. The position of the fanlight is altered and regulated
by means of the ratchet bar b, which is turned upon its centre by a handle or other
suitable means, so as to allow the snugs b' to pass through the slots c¹ of the bracket c.
The sides of the slots c' and also the snugs may be chamfered to facilitate the action
of the ratchet bar when being raised or lowered.
I sometimes form a screw thread upon the bar b, as shown at in Fig. 6, and
form a corresponding thread in the bracket c, whereby a fanlight or other article may
be secured after closing the same.
Another form of ratchet bar and bracket is shown in Fige. 7, 8 and 9. The bar b
is formed with projections b, having segmental portions removed therefrom. The
bracket c has openings c to permit the passage of the flanges b². The revolution of
the bar b to the position shown in Fig. 7 fixes the bar at any required height.
The arrangements above described and illustrated in Figs. 1 to 6 may be modified
and applied to other forms of fanlights and skylights and analogous articles, mounted
on pivots or otherwise; and also to sliding, sashes.
for
In fitting my patent screw fanlight regulators, I sometimes enclose the screw in a
tube or tubes, or its or their equivalent, as shown in Fig. 10, in which g is the bevel
or worm gear regulator is the screw: h¹ h¹ are tobes surrounding the screw,
the purpose of screening the same from view, and rendering the device more sightly
and whereby curtains and other articles are prevented from being entangled therein
or soiled. The tubes may be circular, hexagonal, square, or otherwise in section, or
semi-tubes may be used for the above mentioned purpose.
These enclosures or shields may be fitted to the screws in other positions than that
shown in Fig. 10; and the racks and other appliances herein described may be
similarly enclosed and shielded.
When fanlights or analogous articles, or the screw or other regulators, are placed
in inaccessible or inconvenient positions, I fit or make use of various kinds of
permanent or movable connecting rods, for the purpose of actuating the same from a
distance. Such rods usually require to be rotated on their own centres, or otherwise
manipulated, and to communicate such rotation or other motion to or from the screwed
rod or other regulator. When a rigid connecting rod is admissible for the purpose, I
uuite the saine by means of an universal joint or joints, which may be permanent or
detachable. In Figs. 11 and 12 a detachable universal joint is shown. h is the rigid
rod having a square socket, as shown in plan in Fig. 12. The movable rod i has a
squared end, which fits the socket k, and whereby it may be rotated, by hand or
otherwise. The rods and i need not be in line with each other, and may be operated
at various angles.
In
In Figs. 13, 14 and 15, two other forms of universal joints are shown, which will
be readily understood from the drawings. In that shown in Fig. 13 a pivoted block l
is fitted to connect the rods and i, with the requisite amount of flexibility. Figs. 14
and 15 are views of another form of universal joint, at right angles to each other.
this arrangement the link m unites and also supplies the requisite motion and
flexibility to the rods h and i. lu Fig. 16 a form of flexible shafting n is shown
suitable for the objects of my present invention. This flexible shaft may be formed of
thin metal, or other suitable material. Any of the flexible shafts now in use may be
applied to the same purpose. Figs. 17 and 18 are views, at right angles to each other,
in which the roda h and i are united by means of globular connections, having
eccentrically formed grooves surrounded by rings connected to the rods.
Figs. 19 to 23 further illustrate the last mentioned method of formning the universal
joint. The rods h and i are formed with split rings and ends, as shown in Fig. 22,
whereby they are capable of being sprung on to the globe o. The globe o is shown in
section in Fig. 23. grooves o' o are formed at right angles, and also eccentric to each
other and to the globe. When the rods have been so united, as shown in Fig. 19,
collars ppare driven over the split ends of the rods, whereby the rings are prevented
from opening. In Figs. 20 to 23 the rods and globe are shown separated.
Figs. 24 to 27 show other methods of forming the rings to enter the grooves o' of

page_text: in the ball o. In Figs. 24 and 25 one side o³ of the ring is made separate and secured
by screws of
In Fig. 26 the rod his screwed into the collar 72. The ring o' is made in two parts
and also screwed into the collar p. In Fig. 27 the rod h. and the two parts of the
ringo are driven into the collar p, and thereby secured together. These rings may
be otherwise formed and fitted to the rods, and united to the globes and to each
other by various other methods.
Figs. 28 to 31 illustrate a method of fitting the lower ends of the rods with handles.
is a tubular end (preferably of brass) driven on to the rod h, and secured by a pin
p' is a tube (also preferably of brass) cuclosing the rod h. 2 is a square hole
formed in to receive the square end 8' of the key s. This key may be fixed or
movable.
Fig. 32 shows another form of handle for the lower ends of the rods. The end is
recessed on each side to receive the radial levers, which are opened ont when
required for use, as shown by the dotted lines. Fig. 33 is another form of the same
with a single lever. Fig. 34 shows another method of fitting the rod / with a hinged
handles, which hangs vertically, when out of use; the dotted lines showing, the
position, when in use. Fig. 35 shows a more simple form of hinged handle.
.. :
Fig. 36.illustrates a method of operating the lifting screw and travelling nut, (or
any other analogous device) the hook t being inserted in the eye of the screw and
used to turn the same; the hook may he removed if desired. This screw and that
shown in Fig. 41, may be placed in any convenient position.
I also sometimes form the end of the rod has a simple fixed cranked handle, or with
a fixed wheel, as shown in Fig. 37; or with a hinged wheel, as shown in fig. 38.
Fig. 39 illustrates another forin of handle.
In Fig. 40 one of the applications of my improved gearing is illustrated; the
fanlight a being readily manipulated from below by turning the handles. The strutt
may be fitted with a fork at & for the insertion of the rod h. The strut may be hinged
to the wall so as to fold up out of the way, as shown by dotted lines, and the rod h
may also hang vertically near the wall, as also shown by dotted lines.
Another method of applying my improved gearing to a fanlight is illustrated in
Fig. 41. cc are two fixed brackets. is a screw, capable of revolving in the
brackets c c. is a travelling nut to which the connecting rode is hinged. By
turning the screw u with the rod and universal joint at m, the faulight may be

engages in one of the holes w³ of the rack w.
By inserting a rod in the socket ' the catch 2 may be disengaged and the fanlight
regulated, as desired; or the fanlight may be closed by simply pushing up the slide,
or by inserting a hook in the hole 3. Some forms of swing and other fanlights
require a square-ended tooth to secure the slide in both directions.
A slipper guide may be substituted for that shown in Figs. 42 to 45. The bar w
(Figs. 46 and 47) is fitted to the side of the frame, and the guide and catch z are fitted
thereto as shown.; the action being similar to that shown in Fig. 42.

ventilator, for admitting a vertical current of air, in proximity to a window. 1 is a
glass window (in section). 2 is a glass screen. 3 is a horizontal pivoted door. 4 is
a rod for opening and closing the door, 3. 5 is a spring clip to retain the rod 4 in
position, when raised or lowered.
Fig. 49 is another arrangement for a similar purpose. The door 3 is fitted with a
bracket 6, which receives motion from a travelling nut on the screw 7:
In Fig. 50 the door 3 is hinged to the window bar, and receives motion from the
ravelling nut on the screw 7 by means of the connecting rod 8.
