I EDWIN TUDOR OWENS of 12 Bath Street Birmingham in the County of Warwick
Manufacturer do hereby declare the nature of my said invention to be as follows:-
My invention has for its object an improved device for operating fanlights sky-
lights, ventilators and other similar moveable parts of structures so that they may bo
easily opened and closed and secured in either position as well as in any intermediate
position in a very easy simple and inexpensive manner. The device may be fixed
in a variety of positions so as to operate the moving parts when hinged at the top or
bottom or sides or in any other position but I will now explain it as applied to a fan-
light when hinged at the bottom in the usual manner.
My device consists of a cord wheel of peculiar construction hung upon a pivot in
a metallic frame plate in conjunction with an arm which is operated by means of
teeth thereon from a worm upon the face of the cord wheel. The arm at the outer
end is formed with a slot which lays hold upon the neck of a pivot plate which is
secured to the edge or other part of the fanlight or other moving part to be operated
thereby.
The cord wheel is constructed with a curved endless rib or worm upon its outer face
and this wheel is hung upon a substantial pivot which is fast to the frame plate. This
frame plate is substantial in character with a large base upon which the wheel works
and over which a bridge is constructed so as to be practically a part of the frame plate
and this may be accomplished by slotting the ends of the bridge into suitable jaw
projections cast upon the plate through each end of which a pin or screw is after-
wards passed. The bridge is slotted upon its face and is shaped to form a substantial
joint for the base of the arm or lever which is hung therein. This arm or lever is at
its back end formed like the segment of a toothed pinion the teeth of which enter
into the worm or endless rib upon the outer face of the cord wheel in such a manner
that the arm is turned upon its joint when the cord wheel is operated by a cord from
any required direction. The outer end of the arm is fitted with a slot which finishes
with a sufficient enlargement to receive the collar at the end of the pivot bracket when
. n .

page_text: the smaller part of the slot works between the said collar and the back shoulder upon
an oblong oval or double curved neck or pivot piece on the bracket. The other part of
the bracket is formed to suit the position or part upon which it is fixed. Instead of
the fast collar we may use a loose one without an enlargement in the slot of the
arm.

and other similar Movable Parts of Structures.
I EDWIN TUDOR OWENS, of 12 Bath Street, Birmingham, in the county of Warwick
Manufacturor, 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 :-
My invention has for its object an improved device for operating fanlights, skylights,
ventilators, and other similar moveable parts of structures, so that they may be easily
opened and closed, and secured in either position as well as in any intermediate
position, in a very easy, simple, and inexpensive manner. The device may be fixed
in a variety of positions, so as to operate the moving parts when hinged at the top or
bottom, or sides, or in any other position, but I will now explain it as applied to a
fanlight when hinged at the bottom in the usual manner.
My device consists of a cord wheel of peculiar construction hung upon a pivot in
a metallic frame plate in conjunction with an arm which is operated by means of teeth
thereon from a worm upon the face of the cord wheel.
The arm at the outer end is formed with a slot which lays hold upon the neck of a
pivot plate which is secured to the edge or other part of the fanlight or other moving
part to be operated thereby.
The cord wheel is constructed with a curved endless rib or worm upon its outer
face; and this wheel is hung upon a substantial pivot which is fast to the frame plate.
This frame plate is substantial in character, with a large base, upon which the wheel
works, and over which a bridge is constructed so as to be practically a part of the frame
plate, and this may be accomplished by slotting the ends of the bridge into suitable
jaw projections cast upon the plate through each end of which a pin or screw is
afterrwads passed.
This bridge is slotted upon its face, and is shaped to form a substantial joint for the

page_text: base of the arm or lever which is hung therein. This arm or lever is at its back end
formed like the segment of a toothed pinion the teeth of which enter into the worm
or endless rib upon the outer face of the cord wheel in such a manner that the arm is
turned upon its joint when the cord wheel is operated by a cord from any required
direction.
The outer end of the arm is fitted with a slot, which finishes with a sufficient
enlargement to receive the collar at the end of the pivot bracket, when the smaller
part of the slot works between the said collar and the back shoulder upon an oblong,
oval, or double curved neck or pivot piece on the bracket. The other part of the
bracket is formed to suit the position or part upon which it is fixed.
Instead of the fast collar we may use a loose one, without an enlargement in the
slot of the arm.
Having now described the nature of this my invention, I will proceed to explain
more fully how it may be performed, having reference to the accompanying illustrative
sheets of drawings upon which are figures and letters of reference, similar letters
referring throughout the several views to the same thing or part.
Fig. 1, is a side elevation, and Fig. 2, a front elevation showing this my invention
as applied for opening or closing a casement hinged at its bottom end.
Fig. 3 is a section upon line A-B Fig. 1.
Fig. 4 is a front elevation of the worm wheel.
Fig. 5 is a side elevation, and Fig. 6, a front elevation of a modified form of
bracket carrying worm wheel &c., and operating similarly as Fig. 1 &c.
Fig. 7 shows a section through the centre of worin wheel &c.
Fig. 8 illustrates a modification which is made to operate upon a casement hinged
at its upper end.
Fig. 9 shews a front view of Fig. 8.
Fig. 10 represents how it may be applied to a skylight or similar structure.
Fig. 11 is a plan of Fig. 10.
Fig. 12, is an elevation of Fig. 11.
Fig. 13, is a complete view on a small scale of Fig. 12.
I will first describe it as illustrated in Figs. 1, 2, 3 & 4.
a,
is the frame of the window &c., and the casement or other moveable part,
which is hinged or jointed at its lower end. c, is a cord wheel or pulley over which
the manipulating cord passes; being guided by guide pulleys or rollers d.
Upon the face of this pulley c is provided an endless involute rib or tooth e, or this
rib may be upon its periphery, its sectional form answering to that of gear wheel
tooth. This pulley and wheel is mounted upon a substantial pivot f, which is secured to
the frame plate g. This frame plate g, is secured firmly to the fixed structure a, by
means of screws at h. Upon the frame g is formed a joint i, which receives the
quadrantj, the outer end of which operates in conjunction with a suitable bracket k
upon the casement b. Upon the short or inner end of this quadrant bar or lever j, is
formed a segment of a toothed pinion which takes into or gears with the worm rib
before described.
It will now be apparent, that upon a circular motion being given to the pulley c, the
rib e will cause the lever to move in a given direction upon the joint i.
Upon the casement &c. b, I provide a bracket k, having a neck part which engages
in a slot m upon the arm j.
This armis enlarged at its one end to admit of the outer collar n passing
therethrough.
Hence, upon motion being given to the pulley c, the arm is moved upon its centre,
carrying with it the bracket k, and thus the casement is opened or closed.
In Figs. 5, 6, & 7 I have shown a modified form of frame plate g³, and a consequent
modified form of the quadrant bar 1; which is somewhat neater in appearance. It
will here be seen that the plate g¹ is let in, or morticed into the frame a, and the cord
wheel reversed, having the rib e, on the inside. Its motion and its operation upon the
casement b, however will be clearly understood to be similar to that of Figs. 1, 2, & 3.

page_text: Again in Figs. 8 & 9 I have illustrated a modification in form and application, in
which the casement is hinged at its upper end, and in which the said casement is
pushed outwards instead of inwards, as previously described and illustrated.
In this case the position of the pulley c, and the toothed segment is similar to that
of Figs. 1, 2, & 3. The toothed segment l; is extended sideways at its upper part to
the quadrant bar. The said bar being rigidly connected to, or in one with the
toothed segment 1. k¹ is a bracket having a rod o, upon which the joint piece p slides,
which said piece p, is jointed to the bar 2, thus dispensing with the slot as previously
shewn.
From the previous description its action will be understood, the dotted lines shewing
the altered position the parts would assume upon the opening of the casement to that
point.
In Figs. 10, 11, 12, & 13 I further illustrato its application in a modified form to
the operating of a skylight. In this case it will be seen that the frame plate 9³, is
similar to that in Figs. 1 & 2, having an angle plate q, by which it is attached to the
fixed structure a. To connect the end of the bar to the casement, I have shown a
link r, having a ball and socket joint at each end, the one end being connected to the
end of the bar j³, and the other end to the said skylight or casement.
In order the more clearly to explain Fig. 12, I have shown it more completely on
a reduced scale in Fig. 13.
If desired, the worm or endless rib may of course be formed upon a separate wheel
from the cord pulley, both however will work in conjunction with each other, that is,
the worm will be operated by the cord pulley or its equivalent.
Also guides and guide pulleys for the cords may be fixed in any desired position,
in order that they may be made to operate from any given direction.
Although I have shewn this my invention in several ways for the purpose of
explaining how it may be applied, yet it will be clear that the details may be variously
modified without departing from the nature of the invention, and therefore I do not
confine myself to such details shewn, or their precise arrangement.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. The combination and arrangement of a segmental toothed lever or quadrant
bar, with a worm wheel, constructed and operating substantially as described and
illustrated, and for the purposes set forth.
2nd. The quadrant bar or lever, having a toothed surface provided thereon to engage
with a worm wheel, substantially as shown and for the purposes specified.
3rd. The operating of a toothed lever, by means of a spiral rib or worm, in conjunc-
tion with a cord wheel or pulley, substantially as shown, and for the purposes
specified.
4th. The combination of any such, or similar parts hereindescribed and illustrated,
constituting an arrangement for operating fanlights, skylights, ventilators, and other
similar moveable parts of structures.
