COMPLETE SPECIFICATION.
Improvements in Means and Appliances for Opening, Closing,
Regulating, and Fastening at any Desired Angle, Swing
Windows, Ventilators, Fanlights, 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 performed, to be particularly described and ascertained in and by the following
statement :-
Whereas the subject matter of the present application for Letters Patent, was
originally filed with the Complete Specification of my former Patent dated
December 2nd 1887 No. 16610, and was described and illustrated therein.
And whereas the Comptroller General of Patents objected to such subject matter
and ordered the Specification to be amended by the withdrawal of such subject matter
and the drawings referring thereto.
And whereas the decision of the Comptroller General of Patents was confirmed on
appeal to the Law Officer.
My invention relates to opening, closing, regulating and fastening, at any desired
angle, swing windows, ventilators, fanlights and analogous articles, whether in groups
of two, three, or more, or singly and the object of my invention is to effect
improvements therein.
:
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.
Fig. 1 is an elevation, Fig. 2 a plan, showing the Fanlight partly open and Figs. 3
to 8 are detail views, showing one form of stay.
c2
a is the transom or frame: bis the fanlight, hinged at the bottom. c is an arın,
e is a slotted rack screwed to the
attached to the transom by the universal joint d.
top bar of the fanlight. This rack is shown separately in Figs. 3 and 4. Fig. 3
being a plan, and Fig. 4 a section on the line 1-2 of Fig. 3. e is the slot and eare
serrations formed upon the rack. is a latch which engages the arm c when the
fanlight is closed, and secures the same. c' is a small bolt passing through the arm c,
and having a ring c² pivotted under the bolt. This bolt is also fitted with a snug g
shown separately in Figs. 5, 6, 7 and 8., in which Fig. 5 is a top view; Fig. 6 is a
side view: Fig. 7 is a front view, and Fig. 8 a back view. This snug is preferably
bored through, vertically to receive the bolt c. The back of the snug has serrated
teeth g', which engage in the rack e², when the arm c is not lifted. is a cord, one
end of which passes through a hole e in the rack e, and is fastened thereto with a
knot. The snug may be otherwise formed, and is in some cases formed in one with
the pin c¹.
The cord is then passed through the ring c², the hole e³ in the rack, and a hole in
the bracket (screwed to the fanlight). The other end 12 of the cord is passed
round the pulley a¹, or its equivalent, and fastened with a knot at ' to the bracket 1.
If the Fanlight is open, it can be closed by simply pulling the cord A², thereby
causing the snug g to travel over, the teeth e².
In order to open the fanlight, the snug g is lifted, whereby it is disengaged from
the rack e and enabled to slide in the slot e¹, the fanlight being opened and fixed in
any required position.
In some cases the cord h, the bracket &', and the pulley a¹ are dispensed with; and
5 the ring may be lifted by hand, or by means of a hook and rod, the opening and
closing of the fanlight being thereby readily effected.
In Figs. 11, 12, 13, 14 and 15 a reversible rack is shown, which will be found
convenient for fitting the arm to act right or left-handed.

page_text: Fig. 11 is a front elevation of this form of rack, Fig. 12 is an end view. Fig. 13
is a section on the line 3-4. Fig. 14 is a plan, and Fig. 15 is a section on the
line 5-6.
The rack is formed in two parts, or in any other convenient manner, but I prefer to
use the following arrangement; e is a frame secured to the fanlight by screws aa.
e is a reversible serrated rack, fitting into the frame e, and secured to the fanlight
by screws y y. The rack is provided with double countersunk holes at 2, Fig. 13.
With this rack I prefer to use a snug or pawl attached to the arm of the form shown
at w in Fig. 15. This pawl we will act in the required manner with the rack e turned
for right or left action.
Fig. 9 is a top view and Fig. 10 a sectional elevation showing my improved flexible
arm or stay applied to the purpose hereinbefore described. is a bracket to which
the flexible stay is pivotted. ¹ is the bolt fixed to the same, carrying the snug g²,
2 is a ring attached to the snug g2, as or similar to that before described. Figs. 16
and 17 are front elevations of this arrangement, the form of the rack.being clearly
shown in Fig. 9.
The snug g2 consists of a circular cone formed in one with a flat plate. The flat
plate is capable of sliding between the circular openings or serrations in or on the
plate e, when the snug g is drawn down, as shown in Fig. 17, by means of a cord or
otherwise, as herein before described. The flexible stay may be so formed as to act
as a spring, having a tendency to raise the snug g², and thereby fix the same in one
of the circular openings. When a lazy jointed stay is used, I prefer to make use of
a suitable spring inserted to keep the snug g² in position. is a bracket having
pin (as shown, or of other suitable shape) which enters a corresponding hole fin
the stay c³. Other suitable catches may be used. When the fanlight is closed the
pin f, enters the hole f2 and secures the fanlight in that position.
a
Figs. 18 to 24 illustrate another method of applying flexible stays for the purposes
aforesaid, in which Fig. 18 is an elevation showing the fanlight & closed. Fig. 19 is
a sectional elevation showing the fanlight open. Fig. 20 is a plan view of Fig. 19;
and Figs. 21 to 24 are enlarged detail views of the lock.
The flexible stay is pivotted to the transom or frame at i, and is pierced with holes
for the passage of the bolt c. The free end of the flexible stay passes between two
clips forming parts of a pivotted guide k. . is a casting, formed in one with the
front plate. This casting is mortised into the rail or stile of the fanlight, and is secured
thereto by the plate as shown. c² is a ring attached to a lever meshing into the
bolt c, as shown in Figs. 22 and 23 (with or without a spring for raising the bolt)
m is a hole in the transom or frame to receive the bolt c (which may be of any
suitable shape or form) when the fanlight is .closed. By raising the ring e² by hand
or with a hook, cord, or other appliance, the fanlight is capable of being opened, and
the fanlight can be set open at any desired angle, as shown in Figs. 19 and 20.
Figs. 25, 26, 27 and 28 illustrate another method of applying flexible stays for the
purposes aforesaid, in which Fig. 25 is a plan view, Fig. 26 is a partial view, Fig. 27
is a section, and Fig. 28 is a partial front view, showing the bolt withdrawn to release
the fanlight.
a is the transom or frame, e³ is the flexible stay, e' is a plate fitted upon the rail,
stile, or frame of the fanlight, and formed in a similar manner to that shown in
Fig. 9. is a plate carrying the snug g which gears into the openings in the plate e'.
The snugg
is provided with a bolt c which enters the recess m in the transom, when
the fanlight is closed and secured. The spring o surrounds a short bolt p rivetted
to the stay. This spring keeps the snug g locked in one of the holes of the plate e',
until it is drawn down, as shown in Fig. 28. In some cases I make the bolt p of a
suitable form and so fitted as to operate similarly to the pin c*.
Figs. 29 to 34 show other forms and methods of utilising my flexible stays. Fig. 29
is a plan and Fig. 30 a vertical. section, showing the fanlight closed. Fig. 31 is a
plan, and Fig. 32 a vertical section, showing the same fanlight open. The Fanlight
in Figs. 29, 30, 31 and 32, are shown opening inwards. Fig. 33 is a plan and
Fig. 34 a vertical section of a fanlight opening outwards..

page_text: In these Figures a is the transom. is the rail or stile of the fanlight. c is the
flexible stay, pivotted to the transom at i. The end t of the stay is fitted with a
traveller nut roller or other projection which slides in the mortice under the plate e,
and retains the end of the flexible stay in contact with the slotted plate e. The lever
arm is fitted at s with a suitable appliance for actuating the same and thereby
regulating the position of the fanlight.
The apparatus hereinbefore described is applicable to fanlights hinged horizontally
or vertically and may be constructed with obvious modifications and additions, and in
combination with my well known appliances for the purposes aforesaid; and in fixing
the same to various windows those parts described as being fixed to the transom or
frame may be attached to the sash or otherwise.
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. The method of opening, closing, regulating, and fastening at any desired angle,
swing windows, ventilators, fanlights and analogous articles, by means of a stay c
rendered flexible by means of a modified universal joint d, substantially as hereinbefore
