IMPROVEMENTS IN THE APPLIANCES FOR ATTACHING LINES TO SLIDING SASHES OF WINDOWS, and in the PULLEYS EMPLOYED THEREWITH. PROVISIONAL SPECIFICATION
Year: 1873

page_text: LETTERS PATENT to Thomas Harris, of 73, Westbourne Park Road,
Bayswater, in the County of Middlesex, Ironmonger, for the Inven-
tion of "IMPROVEMENTS IN THE APPLIANCES FOR ATTACHING LINES TO
SLIDING SASHES OF WINDOWS, and in the PULLEYS EMPLOYED THEREWITH.
PROVISIONAL SPECIFICATION left by the said Thomas Harris at
the Office of the Commissioners of Patents, with his Petition, on
the 14th March 1873.
I, THOMAS HARRIS, of 73, Westbourne Park Road, Bayswater, in the
County of Middlesex, Ironmonger, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE APPLIANCES FOR ATTACHING LINES TO
SLIDING SASHES OF WINDOWS, AND IN THE PULLEYS EMPLOYED THEREWITH," to be
as follows, that is to say :-
The object of my improvements is to facilitate the application of tho
lines to the sashes of windows, and avoid the removal of the same when
new lines are required.
The first part of my Invention relates to fixing a metal box having a
moveable cover at each end of the bottom rail of the upper or back sash.

page_text: This box is preferably made of a shape similar to and takes the place of
the lower end of the side rail when extended below the meeting rail, as
is usually the case with the better class of sashes, thereby forming an
ornamental finish and adding to the strength of the bottom corners of the
upper sash (a groove being formed along the entire length of the side
rails of the sashes to receive the line).
I construct the aforesaid box with a hole in the top of same, which
when screwed on is exactly opposite the said groove in sash, the line
(which is usually fixed to the sash by nails) is passed down the groove
and through the hole in the metal box and formed into a knot; this knot
will prevent the end of the line being drawn back through the said hole,
thereby attaching the line to the sash. The cover of the box is then
applied and fixed by means of an ordinary screw for wood. In the
lower sash instead of employing boxes to receive and hold the knotted
ends of the lines, I cut a chamber in each end of the bottom rail of the
sash. In each chamber I screw a metal eye through which the end of
the line is passed and knotted as before described. A metal plate is
then screwed on underneath to cover the opening of the said chamber
and also to act as a strengthening plate to the corner of the sash.
I prefer that the above described boxes, covering plates, and screw
eyes should be galvanized in order to counteract the effect of rust on
the same.

By these arrangements nails are not required to attach the lines to
the sashes, and to replace a broken line the beads and sashes need not be
removed; it is simply necessary to remove the cover of the said box or
the metal plate covering the chamber, and to pass the line down the
groove in the edge of the sash and through the hole in the said box or
the eye in the said chamber (as the case may be); the end of the line is
then knottod and the cover or the metal plate replaced as hercin-before
described. The pocket pieces of the weight chambers are so arranged as
to admit of the weights being removed or replaced without the necessity
of taking out the beads or sashes.
The second part of my Invention relates to the construction of an
improved sash pulley, and consists in hinging the part of the frame
carrying the sheave or bowl. to the present plate, so that it may be
brought outwards in a downward direction when a sash line has to be
applied thereto. To carry out this part of my Invention I form in the

page_text: front plate of the pulley frame a larger rectangular opening than usual.
The sides of the frame carrying the pulley are only connected together.
at the bottom, and are hinged to the lower part of the said rectangular.
opening on the front plate. At the back of the front plate the upper-
parts of the side frames are formed with a notch or slot to receive a
catch pivotted to the back of the front plate by which the side frames and
pulley are locked in position. This catch can be raised and lowered
from the front (when the pulley is screwed to the hanging style of the
window frame), by the point of a bradawl, or any other suitable instru-
ment, through a vertical slot in the front plate provided for the purpose.
My improvements in attaching lines to sliding sashes are applicable to
sashes as at present constructed. In this case a groove would have to
be made through the entire length of the sides of the sash.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Harris in the Great Seal Patent Office on
the 12th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL (COME, I, THOMAS.
HARRIS, of 73, Westbourne Park Road, Bayswater, in the County of
Middlesex, Ironmonger, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Harris, Her special licence
that I, the said Thomas Harris, my executors, administrators, and
assigns, or such others as I, the said Thomas Harris, my 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 "IMPROVEMENTS IN
THE APPLIANCES FOR ATTACHING LINES TO SLIDING SASHES OF WINDOWS, AND IN
THE PULLEYS EMPLOYED THEREWITH," upon the condition (amongst others)
that I, the said Thomas Harris, executors or administrators, by an

page_text: instrument in writing under my, or their, or one of their hands and
scals, 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 I, the said Thomas Harris, do hereby declare
the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing hereto
annexed, and to the figures and letters marked thereon, that is to say :-
The object of my improvements is to facilitate the application of the
lines to the sashes of windows, and avoid the removal of the same when
new lines are required.
The first part of my Invention consists in fixing a metal box having a
moveable cover to each end of the bottom rail of the upper or back sash.
This box is preferably made of a shape similar to and takes the place of
the lower end of the side rail when extended below the meeting rail, as
is usually the case with the better class of sashes, thereby forming an
ornamental finish, and adding to the strength of the bottom corners of
the upper sash (a groove being formed along the entire length of tho
side rails of the sashes to receive the line).
I construct the aforesaid box with a hole in its top, which when the
box is screwed on is exactly opposite the said groove in the sash. The
linc (which is usually fixed to the sash by nails) is passed down this
groove and through the hole in the metal box, and its end is formed into
a knot; this knot will prevent the end of the line being drawn back
through the said hole, thereby attaching the line to the sash. The cover
of the box is then applied and fixed by means of an ordinary screw for
wood. For the lower sash I cut out a chamber in each end of the
bottom rail of the sash to receive and hold the knotted ends of the lines.
In cach chamber I screw a metal eye through which the end of the line
is passed and knotted as before described. A metal plate is then
screwed on underneath to cover the opening of the said chamber, and
also to act as a strengthening plate to the corner of the sash.
I prefer that the above described boxes, covering plates, and screw
eyes should be galvanized in order to prevent the same from rusting.

page_text: The pocket pieces of the weight chambers are suitably arranged to
admit of the weights being removed or replaced without the necessity of
taking out the beads or sashes.
The second part of my Invention relates to the construction of an
improved sash pulley, and consists in hinging the part of the frame
carrying the sheave or bowl to the ordinary front plate of the pulley so
that it may be brought outwards in a downward direction when a sash
line has to be applied thereto. To carry out this part of my Invention I
form in the front plate of the pulley frame a larger rectangular opening
than usual. The sides of the frame carrying the sheave or bowl are only
connected together at the bottom, and are hinged at the lower part of
the said rectangular opening in the front plate. At the back of the
front plate the upper parts of the side frames are formed with a notch or
slot to receive a catch pivoted to the back of the front plate by which
the side frames and sheave or bowl are locked in position. This catch
can be raised and lowered from the front (when the pulley is screwed to
the hanging style of the window frame) by the point of a bradawl or any
other suitable instrument through a vertical slot in the front plate pro-
vided for the purpose.
To make my Invention better understood I will now procced to
describe the same by reference to the accompanying Drawing in which
Figure 1 is a plan; Figure 2, a front elevation; and Figure 3, a side
elevation of the metal box for the upper or back sash; Figure 4, section
shewing the said box fixed to a sash, and shewing the knotted end of
the line; Figure 5 is a view (partly in section) of one corner of the
lower sash shewing the method of fixing the line thereto; Figure 6,
outside elevation of a pair of sashes furnished with my improved
appliances for attaching the lines thereto; the dotted lines show the
grooves passing entirely along the sashes; Figure 7, side elevation;
Figure 8, front elevation, and Figure 9 back elevation of my improved
sash pulley, and Figure 10 side elevation shewing the pulley with the
part carrying the sheave or bowl brought outwards in a downward
direction for applying the line thereto. Similar letters in all the Figures
represent similar parts.
The metal box fixed at each corner of the bottom rail of the upper or
back sash, and shown in Figures 1, 2, 3, 4, and 6 is formed with a
moveable cover a having a pin b at its lower end fitting into a hole c in
the back d of the box; this box is formed of the same width as the

page_text: thickness of the sash, and may be of any other suitable shape than that
shewn in the. Drawing. e is the hole in the top of the box through.
which the sash line passes; the box is fixed to the sash, as. shewn in
Figure 4, by screws through the holes f, f, in the top of the box, the
hole e being then under the groove g in the side of the sash for receiving
the sash line h. The cover of the box is fixed on by the pin 6 fitting in
the hole c, and a screw i passing through the hole ; in the cover screwed
j
on to the sash, as seen in Figure 4. In Figure 5, % shews the chamber
formed in the corners of the bottom rail of the lower sash; and 1, the
metal eye screwed into the sash through which the end of the line
passes; m is the metal plate screwed to the corners of the bottom rail so
as to cover the said chambers. By these arrangements nails are not
required to attach the lines to the sashes, it being simply necessary to
pass the line (before screwing on the cover a of the box or the plate m
as the case may be) down the groove g in the side of the sash and
through the hole E or through the screw eye l, and then forming its end
into a knot n, as seen in Figures 4 and 5, which will prevent the line
being drawn back, and thereby attaches it to the sash. The cover a of
the box or the plate m is then screwed on as herein-before described.
These arrangements allow of a broken line being replaced without the
necessity of removing the beads or sashes as is the case when the lines
are attached by nails. To replace a broken line one end of the new line
is connected to the weight, the pocket piece of the hanging style
being arranged to admit of its being removed without disturbing the
beads or sashes, and the cover a, or the plate m being removed the
other end of the line is passed down the groove g of the sash, and into
the metal box on into the chamber k and knotted, and the cover a or
plate m is replaced.
In Figures 7, 8, 9, and 10, shewing my improved sash pulley o, o¹, is
the part of the frame carrying the sheave or bowl p; the front part o¹ is
of a rectangular form and fits in a rectangular opening formed in the
usual front plate q of the pulley; the sides o are only connected together
at the bottom, and are hinged or jointed at 7, 7, to the back of the front
plate q; s is the notch or slot to receive the catch t pivotting at t¹ on
the back of the plate q, and by which catch the side frames o with the
sheave p are locked in position; u, vertical slot in the front plate to
allow of raising and lowering the catch t; v, stop against which the
part of the pulley frame rests. This improved pulley greatly

page_text: facilitates the application of lines to sashes by allowing of the part of the
frame o, o¹, carrying the sheave or bowl p being brought outwards, as
shewn in Figure 10; this movement is effected by inserting the point of
a bradawl under the catch and raising it free of the notch s, and the
side frames o with the sheave or bowl p can then be moved outwards on
the hinge or joint r, the line being inserted through the rectangular
opening in the front plate of the pulley; the frame o) and sheave p are
moved back to their normal position and locked by moving down the
catch by inserting the point of the bradawl or other instrument
through the slot u.
My improvements in attaching lines to sliding sashes are applicable
to sashes at present constructed. In this case a groove would have to
be made through the entire length of the sides of the sash.
Having now described my said Invention, and the best means I am
acquainted with for carrying the same into effect, I wish it to be under-
stood that I do not confine myself to the precise details herein laid down
and shewn in the Drawing, as the same may be varied without departing
from the principle of my Invention, but what I claim is,—
Firstly. The improved appliances for attaching lines to sliding sashes
of windows, as herein-before described and represented in Figures 1 to 6
of the accompanying Drawing.
Secondly. The improved construction of sash pulley as herein-before
described and represented in Figures 7, 8, 9, and 10 of the accompanying
Drawing.
In witness whereof, I, the said Thomas Harris, have hereto set
my hand and seal, this Eleventh day of September, in the
year of our Lord One thousand eight hundred and seventy-
three.
