I GURNEY LINDOE FALCONAR of Devon House Fishponds in the County of
Gloucester and Number one All Saints Court in the City and County of Bristol
Architect do hereby declare the nature of this invention to be as follows:
To construct of brick or other burnt clay stone concrete or other suitable material
hollow window jambs and thus provide a space for the balance weights to work
in without the necessity of forming a wooden boxing for the same.
To attach direct to the said jambs non oxidable metal slides or grooves for ordinary
sashes sliding doors or shutters.
To substitute for the ordinary wooden sill a similar metal sheathing secured to the
window board or other internal finishing round window and lapped over a narrow
weathered and throated stepping on the freestone or other external sill.
To secure a similar metal bend to the underside of wood lintel to cover the joint
of the upper or outer sash.
To carry the sash cords over double graduated pulleys secured to wooden blocks
on the under side of lintel.
The following is a more detailed description having reference to the accompanying
drawings.
The Drawings comprise four figures and in each figure the several parts are thus
referred to.
a. The space for the weights.
a. Metal parting strip.
b. The brick or masonry hollow jamb. In the Drawings this is supposed to be built
of ordinary and moulded brickwork.
b. Freestone or other external head to window.
c. Wooden lintel.
d. Wood block attached to lintel to take pulley blocks and upper parts of slides s.
e. Pullies arranged in double blocks and graduated in lovel so as to reduce friction.
e. Slots in slides s. for cords and pullios."
f. Stone or other external sill.
g. Window board fillet or other finishing to wall plastering round window and
dowelled screwed or otherwise secured on to sill f.

p. Moveable panel in same insuring easy access to space a.
8. Metal slides or grooves to take sashes.
s. Shield attached to bottom slide to external (upper) sash to protect the joint
made by metal sheathed sill with the jambs.
Bolt working in hollow beads with ordinary slot or else a metal peg.
3. Metal bead on underside of lintel to retain outer sash.

The slides & would be formed of some non oxidable metal probably zinc a hard
alloy or galvanized iron and be of such a cross section as to prove effectual weather
bars and be secured to the hollow jambs by zinc or galvanized iron screws to gutta
nercha or other composition plugs. In order to ensure the easy removal or reversal

page_text: of the sashes for cleaning or repairs each of these slides would be in two lengths as
shewn in Figures 2 and 3 and would be held together at the points of junction by
means of the metal bolts or pegs s².
The brick or stone work forming sides of hollow jambs being thicker than the
ordinary wood pulley stiles it would be necessary in most cases to have double pullies
to carry the sash cords into the centre of spaces a.
Separate pullies might be used or double blocks as shewn in Figure 2 with graduated
pullies so as to reduce the friction.
The pulley blocks would would in any case have to be secured to the underside of
blocks d.
In the Architrave round the inside of window a panel 2¹ would be so secured with
cups and screws as to give easy access to the space a.
This would obviate the ordinary inconvenience of cutting the frames when repairs
to the lines or weights are required.
The metal sheathing to sill would be secured to the window board g. as shewn in
figure 3 with screws and metal clips 1 bedded between the window board and the
stone sill. The joint formed by the sheathing at the junction with the jambs would
be protected by the shield s attached to the bottom of sush slide as shewn in
figures 1 and 3.
It is to be understood that the details herein described and shewn in the accompanying
Drawings although considered to be generally suitable would be capable of alteration
and modification to suit special circumstances without in any way disturbing the
principles involved and which are
First. The forming of hollow brick or other jambs for the weights to work in.
Secondly. The substitution of metal (non oxidable in preference) for wood in those
parts retaining and protecting the sashes and it is these principles individually or
combined and this plan generally which it is hereby sought to protect by letters
Patent.

An Improved Method of Framing Sash Windows, Doors, or Shutters.
I GURNEY LINDOE FALCONAR of "Devon House," Fishponds in the County of
Gloucester and Number One All Saints Court Exchange in the City and County of
Bristol Architect 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 :-
To construct of brick or other burnt clay stone concrete or other suitable material
hollow window door or shutter jambs and thus provide a space for the counter balance
weights or other gearing to work in without the necessity of forming a wooden boxing
for the same.
To attach direct to the said jambs wrought or cast metal slides or grooves for
sashes sliding doors or shutters to work in.
To substitute for the ordinary wooden sill a similar metal sheathing secured to the
window board or otherwise and lapped over a narrow weathered and throated stepping
on the freestone or other external sill.
To secure a similar metal bead or stop to the underside of wood lintel to cover the
joint of the upper or outer sash when closed.
The following is a more detailed description having reference to the Drawings (left
with the provisional Specification).
In the said Drawings the slides and sheathing are shewn to be of wrought metal.
If cast metal were used a slight modification in details would be required to suit the
material.

page_text: It is desired to be understood that although the details herein described and shewn
n the said Drawings are considered to be generally suitable they would be capable
of alteration and modification to suit special circumstances without in any way

It is desired to be understood that although the details herein described and shewn
n the said Drawings are considered to be generally suitable they would be capable

disturbing the principles involved.
The Drawings comprise four figures and in each figure the several parts are thus

The slides s would be formed of metal (non oxidable in preference) probably zinc
a hard alloy of copper or galvanized iron and be of such a cross section (partly
depending on the material adopted) as to prove effectual weather bars and be socured
to the hollow jambs with zinc or galvanized iron screws and gutta percha or other
composition plugs. In order to insure the easy removal or reversal of the sashes
for cleaning or repairs each of these slides could if desired be made in two lengths as
shewn in figures 2 and 3 and would in that case be held together at the points of
junction by means of the metal bolts or pegs or in other suitable manner.
The brick stone or other material forming the sides of the hollow jambs to
which the slides s are attached being thicker than the ordinary wood pulley stiles
it would be adviseable in most cases to have double pullies which might be graduated
as shewn in Figure 2. The pulley blocks would where the slides were (as shewn in
the Drawings) of wrought metal be secured to the underside of blocks d but in the
case of cast metal lugs or flanges could with advantage be cast on the backs of the
slides themselves ready to receive the pulleys.
In the Architrave round the inside of window a panel p¹ would be so secured
with cups and screws as to give easy access to the space a.
This would obviate the ordinary inconvenience of cutting the frames when repairs
to the lines or weights etc. were required.
The metal sheathing to sill could be secured to the window board with screws
and metal clips h¹ bedded between the window board and the stone sill f. or otherwise
as might be practicable.
The joint formed by the sheathed sill at the junction with the jambs would be
protected by a shield attached to the bottom of the sash slido as
figuros 1 and 3.
shown in

page_text: 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. The forming of hollow brickwork or other suitable material as aforesaid the
jambs of sash windows doors or shutters in the place of wood boxing or casing.
Secondly. The substitution of. metal (non oxidable in preference) for wood in
those parts immediately retaining protecting or guiding the sashes doors or shutters
and it is these principles individually or combined and this plan generally which it is
hereby sought to protect by letters Patent.
