Improvements in Appliances for Fastening Skylight Windows,
Fanlights, Ventilators, and for like purposes.
We, SAMUEL HILL of 260 New John Street West, Cabinet Bar Fitter and
FRANCIS JONATHAN HARLO LILLEY of 22 Shakespeare Road Ladywood, Brass
Finisher, both of Birmingham in the County of Warwick, do hereby declare the
nature of this invention to be as follows:-
Our invention has for its object the construction of appliances for opening, closing
and securing skylights, fanlights, ventilators, and other hinged window frames,
whereby a greater length of travel or greater opening is obtained from a slight
movement given to the hand, than is at present possible with the systems and
appliances at present in use.
We are also able to securely fasten our window, ventilator or other frame when
closed; and to effectually hold it open in any desired position without possibility of
accidental or sudden closing.
In carrying our invention into effect, we construct our hinged frame or window
light such as a skylight, in the usual ordinary manner; but we attach to the case-
ment, a lever of metal, wood, or other suitable material, and this lever we preferably
pivot or fulcrum adjacent to the hinged end of the window or light. The other end
of the lever we connect to a link, or cause it to operate upon a link or links, forming
part of a combination of levers known as "lazy tongs." The lever being attached
to or connected with the "lazy tongs," any movement given to the lever will be
considerably increased by the combination of levers in the tongs. The extreme
joint or joints or end of the tongs we connect to the hinged light; so that any
movement of the lever is at once communicated with a considerable increase of
motion to the window or light.
We cause the lever to move in one manner by passing a screw through a portion
of it, or connecting the screw to the lever, and allowing a nut mounted upon a wheel
and held in a fixed position to cause the screw to travel through the nut and thereby
with it the lever. We prefer however to form the lever as the nut and to connect
the screw to the wheel, the wheel being held stationary by a bracket or by any
ordinary arrangement; so that when the wheel is revolved the screw is made to
travel the lever up and down as may be required for opening or closing the
window.
We cause the wheel to revolve by means of a cord or chain, which we pass
around the circumference, and lead off to any convenient position.
Sometimes instead of employing a separate lever in conjunction with the tongs, we
cause the end or ends of one of the pairs of links forming the tongs to be extended
and connected to a screw working through a fixed wheel and nut held in a bracket
in some convenient position, so that when the wheel is rotated as before the pair of
levers are forced in by the travel of the screw, and thus the window is raised.
Instead of carrying a screw from the pair of links, we sometimes carry or connect
them to a nut through which a screw can work, and thus extend or compress the
combination of levers forming the tongs for opening or closing the window; the
screw being caused to travel by means of a wheel or pulley connected to its end,
the pulley and screw being carried or attached in any convenient manner to the
framework of the building.
We do not limit the application of our invention to any peculiar form of light or
window frame; nor to any peculiar arrangement of ventilators or shutter boards;
but employ the same system of construction with ordinary modifications of working

levers cannot be extended or depressed until the wheel is rotated by means of the
cord or other connection being operated upon.

Improvements in Appliances for Fastening Skylight Windows
Fanlights, Ventilators, and for like purposes.
We, SAMUEL HILL, of 260 New John Street West, Cabinet Bar Fitter, and
FRANCIS JONATHAN HARLO LILLEY, of 22 Shakespeare Road, Ladywood,
Brass Founder, both of Birmingham, in the County of Warwick, 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:—
Our invention has for its object the construction of appliances for opening, closing
and securing skylights, fanlights, ventilators, and other hinged window frames,
whereby a greater length of travel or greater opening is obtained from a slight
movement given to the hand, than is at present possible with the systems and
appliances at present in use. We are also able to securely fasten our window,
ventilator or other frame when closed, and to effectually hold it open

In carrying our invention into effect, we construct our hinged frame or window
light such as a skylight, in the usual ordinary manner; but we attach to the case-
inent, a lever of metal, wood or other suitable material, and this lever we preferably
pivot or fulcrum adjacent to the hinged end of the window or light. The other end
of the lever we connect to a link or cause it to operate upon a link or links, forming
part of a combination of levers known as "lazy tongs." The lever being attached
to or connected with the "lazy tongs" any movement given to the lever will be
considerably increased by the combination of levers in the tongs. The extreme
joint or joints or end of the tongs we connect to the hinged light, so that any move-
ment of the lever is at once communicated with a considerable increase of motion to
the window or light.
We cause the lever to move in one manner by passing a screw through a portion
of it, or connecting the screw to the lever and allowing a nut mounted upon a wheel
and held in a fixed position to cause the screw to travel through the nut and thereby
with it the lever. We prefer however to form the lever as the nut and to connect
the screw to the wheel, the wheel being held stationary by a bracket or by any
ordinary arrangement; so that when the wheel is revolved the screw is made to
travel the lever up and down as may be required for opening or closing the
window.
We cause the wheel to revolve by means of a cord or chain which we pass around
the circumference and lead off to any convenient position.
Sometimes instead of employing a separate lever in conjunction with the tongs,
we cause the end or ends of one of the pairs of links forming the tongs to be
extended and connected to a screw working through a fixed wheel and nut held in
a bracket in some convenient position, so that when the wheel is rotated as before
the pair of levers are forced in by the travel of the screw and thus the window is
raised. Instead of carrying a screw from the pair of links we sometimes carry or

screw being caused to travel by means of a wheel or pulley connected to its end the
pulley or screw being carried or attached in any convenient manner to the frame-
work of the building.
We do not limit the application of our invention to any peculiar form of light or
window frame, nor to any peculiar arrangement of ventilators or shutter boards, but
employ the same system of construction with ordinary modifications of working
parts to suit any particular or peculiar form of window, light, or ventilator with
similar advantage.
By this our improved arrangement we are enabled to hold the window or
ventilator firmly and securely in any position between its closed and fully opened
position without fear of any accidental movement being occasioned, seeing that the
levers cannot be extended or depressed until the wheel is rotated by means of the
cord or other connection being operated upon.
In the accompanying drawings
Sheet illustrates our improved arrangement for fastening windows having a
double threaded screw to operate the jointed levers; and
Sheet 2 illustrates one method of carrying our invention into effect when
employing a single or simple threaded screw for the same purpose of operating the
levers.
Figure 1 is a front elevation of a portion of a window frame B having a hinged
window or light A placed within it, upon the side of the frame B we mount a
bracket M having a pulley L for the hand cord or chain N, carried upon the
spindle D within its sides. The spindle D we cause to project from the side of the
bracket far enough to receive and secure a lengthening or connecting piece C which
we employ to permit of our central apparatus being used on windows of varying
widths while the connecting piece C alone is varied in the adaption of one central
portion to another. The connecting piece C we pin or otherwise secure in any
ordinary manner to the end of the pin D and to the end of the screw E for the
purpose of communicating the movement of the hand cord wheel L to the right
and left handed screws E E' which work within nuts K K¹ carried upon or secured
to the free ends of the arms or levers F F¹. The screws E E¹ we carry within
brackets C C C³ secured to or formed upon the back plate C4, which end bracket
we screw or attach to the face of the window frame B.
The jointed levers F, F¹, F', F³ or any number more or less than shown on the
plans Figure 2 and Figure 3; in which Figure 2 is an illustration of the levers
closed and the window in its shut position, and Figure 3 is an illustration of the
levers extended and the window in its open position. The joints fƒ³‚ƒ³‚ƒ³‚ ƒª of
the levers we make of a free nature so that the minimum of friction is caused by
the movement of the levers or rods one upon the other, and to the outer end
of the system of levers we place a bolt or ring H for engaging with the
projecting bracket G which we place upon the face of the hinged window or
light A.
We sometimes employ one screw E as illustrated on Sheet 2 where Figure 4 is
an elevation of a portion of a window frame B and light A, Figure 5 being a plan
with the window closed, Figure 6 a plan with the window open, and Figure 7 a
detail view of the end attachment of the lever F, F to the central spindle or
Screw E.
When employing one screw as illustrated we cause the end of one arm or lever F
to be extended beyond its connection with the corresponding lever or arm F¹ for
the purpose of attaching to the nut K working upon the screw E, and we allow the
ends of the rods or levers F F to be carried upon the screw E by means of the
collar bracket O which is held in position between the bracket C and the recessed
or sunken end of the screw E, by the washer O'. The opposite end of the links
or levers we connect to the bracket G on the window by means of a jaw or link
connection H. The screw we operate by means of a hand chain N working over
a chain wheel L secured to the spindle D on end of the connecting tube or distance

page_text: piece C. Thus when the screw nut is carried backwards or forwards the window is
opened or closed and is effectually and securely held in any position by means of
the nut on the ends of the system of levers as shown on Sheet 1 and Sheet 2. We
do not always employ a screw and nut arranged upon the window or moving frame
to operate our jointed levers as herein before described and as illustrated, but some-
times arrange a vertical or inclined screw placed or carried at or near the side of
the window or frame and having a handle, wheel or other manipulating lever for
operating the jointed rods attached to the movable window ventilator or shutter ;
the rods being constructed and carried upon the window ventilator or shutter similarly
to the manner herein before described and illustrated.
When applying our invention to moving lights, shutters and ventilators without
the use of a screw of any kind to control the movement of the rods or levers, we
attach any ordinary bar or connecting link to the end of the jointed system of levers
and by pulling or pushing the same cause the hinged window or other object to be
moved readily and quickly the motion of the hand lever being slight compared to
the motion of the window or other object :-
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
(1) The construction of appliances for raising, lowering and fastening sky-
light windows, fan lights, ventilators and other like objects, whereby a system
of jointed levers controls the movement, in the manner and for the purposes
hereinbefore described and substantially as illustrated in the accompanying
drawings.
(2) The application and arrangement of a system of jointed levers having a
screw or screws working into a nut or nuts for operating the jointed levers,
substantially as and for the purposes hereinbefore described and as illustrated in
the accompanying drawings.
