Improvements in Devices for Opening, Closing, and Adjusting Fan-
lights, Sashes, and the like.
I, RICHARD RIDGWAY HARRISON trading as Loach & Clarke of No. 20 Essington
Street, Birmingham in the county of Warwick, Brassfounder, do hereby declare the
nature of this invention to be as follows:-
This invention relates to devices for opening, shutting or adjusting fanlights, sashes
or casements; by means of a screw motion acting vortically, and by means of a link
or links, acting in connection with a screw nut, thereby opening sashes or frames
in or out.
The vertical screw is carried by a fixed bracket, and has a cog wheel attached to its
lower end, the cogs of which are made to work in conjunction with a worm or spiral
projection, upon a spindle which is attached to the fixed bracket, and revolves at right
angles to the vertical screw.
The spindle being operated by a cord passage over a pulley at one end, causes the
vertical screw to revolve thereby raising or lowering the screw nut as required. A
tension spring may be used to increase the bearing of the cord upon the pulley, or the
tension may be increased without springs by passing the cord between two bearings
immediately under the pulley, having their centres at less distance apart than the
diameter of the pulley.
The vertical screw may be attached to one end of a rod, and the cog and spiral
gearing to the other end, in which case the pulley is replaced by a handle, to work
the gearing so that the vertical screw may be operated by rod and gearing if desired,
instead of by cord and pulley.
the
Instead of a spiral or wormed spindle, a bevelled cog wheel and cord pulley com-
bined, attached to the fixed bracket, may be used to operate the vertical screw ;
cug wheel upon the pulley and the screw being bevelled to the same angle.
My invention also applies to the construction of the screw nut and link attachments
thereto.

page_text: The nut may embrace the whole, or any part exceeding one half of the circum-
ference of the screw, and rides upon a guide running parallel to the screw, and
attached to the same bracket. The links are attached to the screw nut, by a screw on
either or both sides or upon the face, the other end being attached to a plate
connected with a bracket containing screw holes for fixing to the fanlight frame.
Two lights or frames may be worked simultaneously by attaching two links to one
opener.

1. RICHARD RIDGWAY HARRISON trading as Loach and Clarke of No. 20 Essington
Street, Birmingham in the County of Warwick, 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 relates to apparatus or means for opening, closing or adjusting fanlights
and other windows and frames, enclosing various openings, and which said invention
is an improvement or an amplification of Letters Patent granted to me on the 24th
day of August 1887 and numbered 11508.
Figure 1 of the accompanying drawing represents partly in vertical section, and
partly in side elevation, a fanlight or other window opener, constructed and arranged
according to my invention.
Figure 2 represents a transverse vertical section of the said figure 1, upon the dotted
lines CD.
a is an attachment bracket, secured by top and bottom extended ends a² to a wall,
frame or other object to which the apparatus is to be applied. is a worm or rotating
screw of a moderate pitch, with its ends 2, 3, working respectively within, and
supported by outstanding arms or brackets a³, a', the latter of which is detachably
connected by small screws.
The lower end of the said worm or screw, carries a worm wheel c, which gears or
meshes with the worm d, whose axis d², carries a pulley, while the axis of both
pulley and wheel is supported by a bracket e.
The groove within the pulley is made undulatory or wave like, so that the cord (or.
chain) will have a better grip upon the surface of the said periphery.
is a rising and falling carrier block, through which the screw band, guide rod i
pass; so that on rotation being given to the worm, the block rises or falls.
The carrier block's outer end has a jointed link k connected to it, and by means of
which, a window is opened or closed.
Thus, to operate the apparatus, pull one side of the cord g, when the pulley and
worm is thereby turned, which imparts motion to the screw pin b, through the worm
wheel G₁
and by such rotation, the carrier block is caused to rise or fall, and a window'
or frame to which the arm k is connected, opened or closed.
Figure 1 represents partly in vertical section, and partly in elevation, a modifica-
tion of the converse action of figure 1. In this arrangement, the block is affixed to
the top of the screw, and rises and falls with it, on the said screw being rotated.
a is a carrier bracket, b is a rising and falling screw, with a carrier block at its
upper end-e is a screwed middle worm wheel, confined within brackets, and where-
through the screw passes when rotated, while d is a worm, gearing with the said
worm wheel, and carrying upon its axis, or upon itself, a pulley f.

page_text: Thus, by pulling the cord g in one or other direction, the screw, and the block /
with it, is made to rise and fall and slide upon the rod ; thereby operating the jointed
link k.
Figure 3 represents another form of my invention. In this arrangement, motion is
communicated to the operating screw of the rising and falling carrier block by means
of bevel gear.
« is a bracket attachment framing, b is a worm or screw, whose ends work within
fixed bearings made through brackets, or arms directed from the main attachment
bracket. The lower end of the screw carries a hanging bevel c, which gears with a
second bevel wheel d, of a combined bevel wheel and pulley d, f, through both of
which an axis or pin 2 passes, which is surrounded by a bearing block 63.
Motion is communicated to the bevel wheels, and the carrier block, through which
the screw b, and guide rod i pass, by means of a cord or chain g, passing around the
periphery of the pulley g.
Thus, to open, close or adjust a window, pull the cord, or the endless cord g, which
rotates the pulley and bevel wheel loose upon the spindle, and thereby communicates
motion to the screw b, through the bevel wheel c, and by such turning of the screw,
the carrier block is raised or lowered, and a window or other frame opened or closed,
by the jointed arm or link k.
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.
First. Opening, closing or adjusting fanlights, and other windows and frames, by
a screw b, working within fixed bearings, and operated by worm, and worm wheel
gearing, of which the latter, or the axis thereof, carries a driving pulley, substantially
as set forth in figures 1 and 2.
Secondly. An apparatus for opening, closing or adjusting fanlights, windows or
other frames, consisting of a screw a, worm wheel e fixedly secured at its end, worm d
with pulley e, carrier block 4, and guide i, arm k, and frame a, a², a³, a; and which
said parts are constructed, arranged and work substantially as described and set forth
in figures 1 and 2.
Thirdly. An apparatus for the opening, closing or adjusting of fanlights, windows
or other frames, wherein the operating screw driven by worm and worm gearing, is
made to rise and fall with the carrier block, substantially as described and set forth
in figure 1^.
Fourthly. An apparatus for opening and closing windows and other frames,
making the groove in the periphery of the driving pulley, undulatory or wave like,
as set forth.in figure 2.
Lastly Opening, closing and adjusting fanlights, windows and frames, by a confined
and turning screw, having fixedly secured to one end a bevel wheel, which gears
with a second bevel wheel, carrying a driving pulley; and which said apparatus is
constructed, arranged and works substantially as set forth in figure 2.
Dated this Twenty-second day of October 1888.
