PROVISIONAL SPECIFICATION.
Improved Means for Hanging Sashes to Render them Detachable for
Cleaning or other Purposes.
I, ANNA MARIA AGNES CRISTALL, of 145 New Bond Street, in the County of
London, Artist, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide means for hanging sashes to render them
detachable for cleaning or other purposes.
At the present time considerable inconvenience is experienced in cleaning windows
on account of the difficulty in reaching all the panes of glass, the person cleaning the
window being obliged, either to stand outside, at a serious risk of falling, or else the
sash has to be removed from the sash-frame by displacing one of the inside beads,
a method which is oftentimes the cause of breakage of the panes, and also is very
objectionable because, after a time, the beads become unsightly by their constant
removal and replacing.
Now, according to my invention, I overcome these difficulties in an easy and
efficient manner, by making the two sash lines of either sash, preferably the lower
one, detachable; this I do by providing the end of each of the two sash lines with a
metal piece forming an eye which is capable of being coupled to a hook carried by
the top rail, or the stiles, of the sash. The metal piece forming the eye is so made
that a shoulder upon it prevents the weight carrying the cord into the interior of the
box-frame. There are two of these books, one at each end of the top rail, or one on
each end of the stiles, and they are so shaped as to permit of the eyes on the sash
lines being readily hooked onto, and unhooked from them, and yet, at the same time,
to make the connection secure.
One of the inside beads, instead of being nailed, as is now usual, I attach by hinges,
so that it may be turned out of the way to allow of the ready removal of the same, a
latch or spring catch upon it serves to keep the bead in its closed position when the
sash is restored to its place.
It is not necessary, although preferable, to make both of the sash lines detachable.

COMPLETE SPECIFICATION.
Improved Means for Hanging Sashes to Render them Detachable for
Cleaning or other Purposes.
I, ANNA MARIA AGNES CRISTALL, of 145 New Bond Street, in the County of
London, Artist, 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, reference being had to the accompanying drawings and to
the letters and figures marked thereon, that is to say :-
The object of my invention is to provide means for banging sashes to render them
detachable for cleaning or other purposes.
At the present time considerable inconvenience is experienced in cleaning windows
on account of the difficulty in reaching all the panes of glass; the person cleaning
the window being obliged, either to stand outside at a serious risk of falling, or else
the sash has to be removed from the sash frame by displacing one of the inside beads,
a method which is oftentimes the cause of breakage of the panes, and also is very
objectionable because, after a time, the beads become unsightly by their constant
removal and replacing.
Now, according to my invention, I overcome these difficulties in an easy and
D

page_text: efficient manner, by making the two sash lines of the lower sash detachable. This
I do by providing the end of each of the two sash lines with a metal piece or hood
having an eye which is capable of being coupled to a hook carried by the top rail, or
the stiles, of the sash. There are two of these hooks, one at each end of the top rail,
or one on each end of the stiles, and they are shaped so as to permit of the metal
pieces or hoods on the sash lines being readily hooked onto, and unhooked from,
them, and yet, at the same time, to make the connection secure. The metal piece or
hood having the eye is so made as to prevent the weight pulling the cord into the
interior of the box-frame.
One of the inside beads, instead of being a fixture, as is now sometimes usual, is
attached by hinges, so that it may be turned out of the way to allow of the ready
removal of the sash, a latch or spring-catch upon it serving to keep the bead in its
closed position when the sash is restored to its place.
In order that my said invention may be more fully understood and readily
carried into effect, I will describe the same with reference to the accompanying
drawings.
Fig. 1 is a front elevation, and Fig. 2 a vertical section shewing my invention
applied to the lower sash of a "double-hung" window of ordinary construction.
Figs. 3 and 4 shew, respectively, a front elevation and edge view of a portion of
the lower sash, drawn to a larger scale, and shewing more clearly the means for hanging
the sash.
Fig. 5 is a plan, Fig. 6 a side elevation, and Fig. 7 a longitudinal section of the
metal piece or hood in which is the eye.
Figs. 8 and 9 shew, respectively, a side view and front elevation of the hook.
Like letters refer to similar parts in all the figures.
a is the upper sash, and b, the lower sash. Secured to the upper end of each of the
stiles c, of the lower sash, is a hook d which is countersunk in the sides of the stiles.
e, e, are the sash lines, each carrying, at one end, the ordinary counterbalance weight f
and, at the other end, the metal piece or hood 9. On reference to Figs. 5, 6 and 7
it will be seen that this piece or hood is provided with two holes h and i, the one, h,
being formed in the top for the purpose of receiving the end of the sash line which
passes through it and is secured by a knot on the inside, and the other, i, which forms
the eye before mentioned, being formed in the side for the purpose of engaging with
the hook d. This piece or hood by reason of its shape effectually conceals the knot
and that portion of the hook with which it engages, thereby giving a sightly and
neat appearance. The hook d is furnished with shoulders d', d, near its lower end
(see fig. 9), so that by bearing against the corresponding portions of the recess in
which it lies, a certain amount of the strain is taken off the screws which retain said
hook in place.
When it is desired to detach the sash for cleaning, or for any other purpose, it is
only necessary to disengage the pieces or hoods g from the hooks d, and by turning
the bead about its hinges j, j¹, the sash may be readily removed and brought into
the room where it can be operated on. The bead j, may be provided with a spring
latch k, or bolt, to retain it firmly in its closed position.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I claim :-
The improved means for hanging sashes to render them detachable for cleaning or
other purposes, consisting in the hooks d, carried by the lower sash, and the pieces or
hoods g, having eyes i, and carried by the sash lines, in order to engage with the
said books, so that when the hoods or pieces are disengaged from the hooks, and the
hinged bead turned, the sash can be readily detached and removed, substantially as
described and shewn.
