page_text: LETTERS PATENT to Sigourney Wales, of the State of Massachusetts,
in the United States of America, for the Invention of "A NEW AND
USEFUL INVENTION HAVING REFERENCE TO WINDOWS OR THE SASHES
THEREOF."
Sealed the 1st December 1865, and dated the 13th September 1865.
COMPLETE SPECIFICATION filed by the said Sigourney Wales at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 18th September 1865, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT
KNOWN, that I, SIGOURNEY WALES; of the State of Massachusetts, of the
United States of America, have made "A NEW AND USEFUL INVENTION HAVING
REFERENCE TO WINDOWS OR THE SASHES THEREOF," and I do hereby declare the
nature of the said Invention, and the manner in which it is to be performed,
to be fully described in the following Specification, it being represented in
the accompanying Drawings which make a part of such Specification, and
of which Figure 1 denotes a front elevation of a window frame and its sashes
as provided with my Invention; Figure 2 is a horizontal section of them, it
being taken through the lower sash; Figure 3 is an edge view of the said

page_text: sash; Figure 4 is a corresponding or inner side view of the movable connec-
tion piece or bar employed with each sash; Figure 5 is a vertical section
taken through the sashes, their connection pieces or bars, and the window
frame.
The nature of the said Invention consists in the combination and arrange-
ment of what is herein-after termed a connection bar or piece, and its
fastenings with the window sash, and so as to operate therewith, and within
one of the sash grooves or channels of the window frame, substantially as
herein-after described.
And the nature of my Invention further consists in the combination and
arrangement of a flange or rib with each of the said connection bars and its
sash provided with connections and applied together and within a window
frame, substantially in manner as herein-after explained.
The purpose of my said Invention is to enable a sash to be readily removed
from its window frame in order that the panes of such sash may be more
easily washed or cleaned than when the sash may be in place within the frame.
"The Invention dispenses with all necessity of removing from the window frame
in order to seperate a sash from it either of the usual sash-holding bars usually
pailed or screwed to such frame, and employed to aid in the formation of
either of its sash grooves or channels.
In the Drawings A denotes a window frame made in the ordinary manner,
and having within it two sashes B, C, the frame being so constructed as to.
allow of either of the sashes being moved vertically within it.
In carrying out my Invention I make the sash to which it is to be applied
of a width somewhat less than the distance between the bottoms of its two
opposite window frame grooves or channels diminished by the depth of one
of them. In consequence of this I construct one side bar a of the sash of
a width less than that of the other, viz., b, and with the said sash and in that
groove c which is next adjacent to the bar a I employ a connection piece,
'bar, or slide D, to which I attach or apply one of the cords x, x, of the sash
balancing weights y, y, the other end being similarly applied to the other
bar (viz., the bar b) of the sash. The means of applying the weight cords to
the sash I prefer to be such as will readily admit of the cords being discon-
nected from the sash after it may be taken out of the window frame. For
this purpose there may be a knot or knob a¹ at the end of such rope, and
there may also be a groove b¹ in each vertical edge of the sash, and to extend
down from the upper edge of such sash into a chamber or recess c¹ made,
within the sash, and of a size to receive the kuob or knot. The groove
should have a width at least equal to the diameter of the rope. The knot

page_text: may consist of a helix of wire or a piece of wire suitably bent about a knot
made on the end of the rope. The connection bar or slide D may have a
flange or rib projecting from it, and so as to overlap the outer side of the
lesser upright bar of the sash, the same being in order to support the sash
to better advantage than it would be were the slider D unprovided with such
flange. The said bar or slider D, when within the window frame channel
or groove c has the sash resting against it and its flange. The sash and bar
should have appliances by which they may be readily fastened together or
unfastened from one another from the inner side of the window. For this
purpose there may be two spring latches h, h, applied to the bar or slider
D to operate with two suitable catches i, i, affixed to the window sash.
I would remark that in general the lower sash only of a window frame
need be provided with my Invention, for it is this sash which is the most diffi-
cult to clean on the outside surface of its glass when the sash is within the
window frame, the same arising from the necessity which exists of raising
such sash within the frame in order to gain access to the external surfaces
of its panes. As the lower sash while in the act of being raised or while
elevated will double on or more or less lap on the upper sash, access to the
outer surface of the glass of the lower sash will be difficult if not impossible
to be obtained. With my Invention applied to window sashes it will be a very
simple matter to remove either of them from its window frame and weight
ropes, as occasion may require, their readjustment within the frame being
equally as easy.
What I claim as my Invention is the combination and arrangement of
the slide or bar D and its fastenings with the sash made with respect to
and applied to the window frame, substantially as herein-before specified.
I also claim the combination and arrangement of the flange or rib f with
the bar D, and the sash made and provided with fastenings and applied together
and to a window frame, substantially in manner and so as to operate as herein-
before explained.
In witness whereof, I, the said Sigourney Wales, have hereunto set
