Fanlights, 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 vertically, 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 is made to revolve by a pulley
at its lower end, which is operated by a cord running over guide pulleys carried by
lugs in the same bracket.
A tension spring consisting of a flat plate spring of steel or other metal is made to
bear upon the tension and following cord, so that the action is held in any position
and can be worked either way, with one hand. Instead of working the screw by a
cord and guide pulleys as described an arrangement of spindle and cog wheels acting
at any angle may be adopted.
The action may be so arranged that the opener can be used vertically or
horizontally.
My invention especially applies to the construction of the screw nut, and the gearing
in connection therewith. The nut embraces only about half of the circumference of
the screw, and is held in gear against the thread or worm of the screw, by riding
upon or against a guide running parallel to the screw, and attached to the same
bracket.
By this construction the friction of the screw is diminished, steady working is
secured, and binding from rust or otherwise is avoided.
Two sashes, lights, or frames may be moved simultaneously in the same direction
from the same motion by attaching two links to the screw nut.
Dated this 23rd day of August 1887.

I, 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 the opening, closing and
adjusting of fanlights, and other windows, consisting essentially of a rising and falling
screw, working within a screw box, outwardly formed into a pulley, which is disposed
between the divisional parts of a bracket, carried by an upright carrier, secured to a
window frame, or building wall; and around which said pulley, and also two guide
pulleys, carried by the lower bracket, an operating cord passes, which is held up to
its work, by a yielding tension plate.
The upper end of the screw has fixedly secured to it, a sliding carrier or block,
which is guided by a vertical rod, and with the rear end embracing the sides of the
upright carrier as aforesaid.
The rear end of the sliding carrier, is jointedly connected to an arm, whose upper
end is jointedly connected and keyed to the outer end of a bracket, fixedly secured to
the frame of a fanlight or other window.
I will now proceed to describe with reference to the accompanying drawings, the
manner in which the same is to be performed.
Figure 1 represents partly in vertical section, and partly in elevation, a device or
means for opening, closing and adjusting fanlight and other windows, and which said
device, or means, is shown applied to a fanlight.
Figure 2 represents a front elevation of the same, and figure 3 represents a trans-
verse vertical section, on the dotted lines A B figure 1 thus showing the carrier which
is fixedly secured to the summit of a travelling and vertically directed screw, which is
raised and lowered, by the rotation of a combined screw box and pulley, disposed
between two standing out brackets, at the lower end of an upright carrier, secured to
one of the uprights of a window frame, or other parts of a building, in juxta position
to a window.
Figure 4 represents a transverse section, on the dotted lines CD, figure 1, showing
the positions of the guide pulleys, in respect to the combined screw box and pulley,
as aforesaid, and also the tension plate, which produces a constant pressure, upon the
cord, thereby ensuring friction or bite, for the efficient raising and lowering of a sash,
or opening of a window.
Figure 5 represents in front elevation, with the top part in section, a modification
of my invention, in which the arm is made to swivel upon the side, instead of coming
in a direct line with the device, as in the preceding figures.
Figure 6 represents my invention, applied with gear, for transmitting the necessary
motion, to the loosely working, screw box, through whose middle, the iravelling or
raising and lowering screw, passes.

page_text: The same letters of reference, indicate corresponding parts in figures 1 to 4.
a is an upright carrier, secured to a fixed framing or wall b, and a¹, a², is a sub-
divided standing out bracket, and between the parts a, a, a combined screw box and
pulley c, is disposed, and through the screwed middle of which, a travelling, and.
vertically directed screw d, passes, whose upper end is surmounted by a fixedly secured
sliding carrier ², which is raised and lowered with the scrow, and to its outwardly
directed end or part, the lower end of an arm or long link e, is jointedly connected
at e².
fis a fixed guide rod, upon which the sliding carrier d³, slides, and is guided; and
which said carrier's rear end d³, is gapped, and with the terminations of the gapped
part, embracing the two opposite sides of the upright carrier; so that the sliding
carrier is guided by its rear end, and fixed rod, whilst it is raised and lowered with,
and by the rising and falling screw d.
The upper end of the arm or long link e, is jointedly connected to the cranked end g²,
of the bracket arm g, which is connected to the fraining of the fanlight h, jointedly
connected at its lower end, to the framing b.
The cranked end of the bracket arm is reduced, and has an car g³, upon its
extreme outer end, which forms the means for locking the saine, to the arm, whose
eye or connection, is made of a like figure.
Supported by the lower part a² of the carrier bracket, are two guide pulleys i, over
which, and around the pulley e, a cord j passes, and is forcibly impressed or made to
bite upon the pulleys, by the tension plate, whose upper end is fixedly secured to
the bracket a¹.
By pulling one or other of the sides of the cord j, the combined screw box and
pulley c, is rotated, which raises or lowers the screw d, and with it, its sliding carrier d²,
thus opening or closing the fanlight, through the intervention of the arm or long
link, and bracket e, g.
In figure 5, a² is the standing out bracket, carrying the guide pulleys, a is the
upright carrier, is the rising and falling screw, carrying at its upper end, a sliding
carrier d, with a trunnion like arm d, on its side, with reduced end d³ at its end,
upon which the end e³, of an arm or long link e, jointedly takes. The lower end of
the arm, is jointedly connected to a bracket g.
In figure 6, a is the upright carrier, a', a², the outstanding brackets, between which,
the combined screw box and bevel or mitre wheel c, takes, and through the screwed
middle of which, the raising and lowering screw, passes.
is a second bevel wheel, with a pulley i, at the outer end of its axis, which works
within bearings, made within the depending bracket a³, of the bracket a², whilst the
lower outwardly directed end of the bracket a', is made into a guide, wherethrough
the cord j, which passes over the pulley i, passes.
Thus, on the pulling of the cord j, or one or other of the sides of the cord j, the
pulley is rotated, which imparts motion to the bevel wheel c², which in its turn,
rotates the combined bevel wheel, and screw-box c, thus raising or lowering the screw,
which is provided with parts as in figure 1.
The bevel wheel c², instead of working above the bevel wheel c, I arrange it below;
so that the pull on pulley, and wear of axle of wheel c², always keeps the teeth of the
bevel wheels in mesh.
Figure 7 represents a modification of figure 6.
d is a rising and falling screw rod, to the upper end of which, the connections for
opening and closing a window, are secured, c³ is a screw-box, at the upper end of the
tube c, down the middle of which, the lower end of the rising and falling screw,
passes. The screw box is worked by a rod co, having at its lower end, a bevel wheel c,
which is driven from the bevel wheel c', upon an axis c³, whose outer end is provided
with a winch or handle ct, for communicating to the said screw parts, through the
intervention of the parts, as aforesaid.
The application of my invention to windows in general, and to skylights, differs in
no essential respect from its application to that of a fanlight, as herein described and
set forth.

tion, and in what manner the same is to be performed, I declare that what I
claim is.-
First. Opening and closing, or adjusting fanlights, and other windows, by a rising
and falling, or travelling screw, or screwed rod, which passes through the middle of a
revolving screw-box, loosely embraced between checks, or sub-divided brackets, and
also carrying with it, a rigidly connected sliding carrier or block, whereto, one end of
the main operating arm of the closing appliance, is jointedly connected, substantially
as described and set forth.
