PROVISIONAL SPECIFICATION left by the said Henry Atkinson and
Robert White at the Office of the Commissioners of Patents, with
their Petition, on the 8th October 1873..

We, HENRY ATKINSON, of Wharf Road, City Road, in the County of
Middlesex, and ROBERT WHITE, of Stafford Road, Bow, in the: said
County, do hereby declare the nature of the said Invention for “A
NEW OR IMPROVED METHOD OF OPENING AND REMOVING. WINDOW AND OTHER
SLIDING SASHES," to be as follows:—
The object of this Invention is to enable any servant or other person
to open the sashes of windows, and to lay or place them horizontally
for the purpose of cleaning the outsides of the glass therein without
detaching such sashes; and also to remove sashes from the frames in

page_text: which they work with the greatest ease and expedition, for the purposes
of cleaning, repairing, painting, and the like.
"
The means by which we propose to attain the said object of our
Invention are as follows:-Instead of attaching the lifting lines or cords
to the sash as usual, the said lines are secured to two rebated strips of
wood of the same length as the styles of the sash, one on each side,
which rebated strips slide up and down in the usual groove in which
the sash styles now work or slide. We pivot with a sliding bolt on one
or both sides the sash styles to the said strips" of wood near their lower
ends, and secure the upper parts of such sash styles thereto by inserting
a flat or plate key in a sunk recess formed or cut in the upper parts of
both sash styles and rebated strips, and the whole slide up and down in
the usual way.
In order to make the sash and rebated strips fit well or tightly
together so as to prevent draughts of air, we form a small recoss in the
upper and lower parts of each side style of the sash, and partly cover
them with a metal plate firmly secured thereto. On the said rebated
strips and opposite each of the said recesses we so fix a metal tongue or
spring plate that each takes into its corresponding recess in the sash
style when closing such sash, and thus forces and holds the two closely
together.
То open the window sash it is only necessary to draw out the said
plate key from the upper parts of the sash and rebated strips, and then
to turn the sash on its bolts, pins, or pivots, when the outside of the glass
can be cleaned within the room as easily and as expeditiously as the
inside; thus avoiding the present costly method of cleaning the outsides
of windows and the risk of accidents.
When it is required to remove the sash, say to insert a pane of glass,
it is only requisite to draw out the plate key and to slide the pivotting
bolts clear of the rebated strips, and the sash is free and can be taken a
to any convenient place for repairs, and thus avoid the dirt usually made
in repairing windows and all damage to the beads and painting.

filed by the said Henry Atkinson and Robert White in the Great
Seal Patent Office on the 8th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
ATKINSON, of Wharf Road, City Road, in the County of Middlesex,
and ROBERT WHITE, of Stafford Road, in the said County, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of October, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Henry Atkinson and Robert White, Her
special license that we, the said Henry Atkinson and Robert White,
our executors, administrators, and assigns, or such others as we, the
said Henry Atkinson and Robert White, our executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "A NEW OR IMPROVED METHOD OF
OPENING AND REMOVING WINDOW AND OTHER SLIDING SASHES," upon the
condition (amongst others) that we, the said Henry Atkinson and
Robert White, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Atkinson and Robert
White, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement thereof, that is to
say:
•
The object of this Invention is so to fix window and other sliding
sashes that any ordinary servant or other person may easily open such
sashes, and lay or place them horizontally for the purpose of cleaning
the outsides of the glass therein without detaching the said sashes; and

page_text: also to remove sashes from the frames in which they work with the
greatest case and expedition, for the purpose of cleaning, repairing,
painting, and the like.
In order that our said Invention may be more easily and more fully
understood and be more readily performed, we now proceed to explain
the same with the aid of the accompanying Drawing which forms part
of this Specification, reference being made thereto by the numerals and
letters marked thereon, and which reference applies to each Figure of
the said Drawing where the same index numerals and letters appear.
Figure 1 is an elevation of a window shewing the lower sash (in
perspective) open and laid down ready for cleaning.
Figure 2 is an enlarged elevation of the side sash stile and of our
rebated sliding strip with the details of our improvements.
Figure 3 is a horizontal plan of the top of the said stile and strip
shewing the position of our improved fastening key; Figure 4 is a side
elevation of the said fastening key.
Figure 5 is a side elevation of a steel spring for holding the sliding
strip in position.
Figure 6 is a side view of a steel spring for pressing the sash stile and
sliding strip closely together; Figure 7 is a front view of the same.
Figure 8 is a perspective view of the pivot on which the sash turns on
being opened and closed.
Instead of attaching the lifting lines or cords to the sash as usual, we
secure such lines to two rebated strips of wood a of the same length as
the stiles 6 of the sash, one on each side thereof, which strips a slide up a
and down in the usual grooves in which sashes now work or slide. Wo
pivot with a bolt c on one or both sides of the sash the stiles 6 to the
strips a near their lower ends, and secure the upper parts of the stiles 6
to the strips a by inserting a flat or plate key d in a sunk recess formed
or cut in the said upper parts of the stiles b and strips a, see Figure 2, 3
and the sash and strip a slide up and down together.
In order to make the sash and strips a fit closely together so as to
prevent draughts of air, we form a small recess in the upper and lower
parts of each stile b, and partly cover such recesses with a metal plate e
firmly secured to the said stiles on the strips a, and opposite each of
the said recesses we so fix a metal tongue or spring ƒ that each such

page_text: spring takes into its corresponding opposite recess in the stile b on
closing the sash, which operation forces the spring f well into such
opposite recess, and thereby draws the strip a and the stile 6 closely
together.
When it is required to open the window sash it is only necessary to
draw the plate key d out of the recesses formed for it in the upper parts
at g of the strips a and stiles b, and then to turn the sash on its bolts,
pins, or pivots c, and lay it upon a table or other support, when the
outsides of the glass can be cleaned within the room as expeditiously as
the inside, thus avoiding the present costly method of cleaning the
outsides of windows and the risk of accidents. When the sash is open
or laid down the strip a is prevented from flying up and is held in place
by the spring which counteracts the action of the sash weight.
When it is desired to remove the sash it is only requisite to remove
the key d as previously described, and to tip or press downwards one
side of the sash when the pivotting bolt c is thereby freed from the
stile b, and the sash is free and can be taken from its place without
injury to the beads and painting, and conveyed to any convenient spot
where it can be cleaned, repaired, painted, or otherwise dealt with, thus
avoiding the dirt generally made in repairing windows.
Having thus fully described the nature of our said Invention and the
method of performing the same, we wish it to be understood that we do
not confine ourselves to the precise dimensions or forms of the details
now illustrated as they admit of variation, but we claim as our Inven-
tion and desire to secure by the aforesaid in part recited Letters Patent,
the method of opening and removing window and other sliding sashes,
substantially as and for the purposes herein described and shewn in the
Drawing.
In witness whereof, I, the said Robert White, on behalf of myself
and the said Henry Atkinson, have hereunto set my hand and
scal, this Eighth day of April, in the year of our Lord One
thousand eight hundred and seventy-four.
