PROVISIONAL SPECIFICATION.
Improvements in and relating to Window Sashes and Frames, and
to other Articles Hung by Weights.
We, ROBERT AMBROSE, and FREDERICK CHARLES AMBROSE, both of 29 Providence
Street, Plymouth, in the County of Devon, Joiners, do hereby declare the nature of
this invention to be as follows:-
This invention relates to certain improvements in window sashes and frames
whereby the sashes can be easily and quickly taken out of the frames when it is
required to clean or paint them, to repair broken sash lines, and for other purposes,
the invention being also equally applicable to shutters and other articles hung by
weights. The invention may be adapted to the sashes and frames and the like in
their manufacture, or may be applied to those already in use.
In fitting window sashes and frames with our invention, we provide the pulley
style of the lower sash with removeable pocket pieces on to which the parting bead
between the two sashes is rigidly affixed or formed in one with the said pocket
pieces. One of the said removeable pocket pieces is preferably made in two or more
sections hinged or pivoted together so that when the lower sash is open and the
attached parting bead pulled out, the upper section or sections may be slid down
between the sash and the pulley style, and may be entirely removed from beneath
the lower sash. Into the space or groove so left the frame of the lower sash may be
pushed laterally and may then be removed from the other side. The parting bead having
been removed with the pocket piece, the top sash can be similarly removed by lowering
it to the bottom of the frame.
For the hanging sashes a hole is bored near the top of the groove for the cord,
transversely and sloping upwards. Into this hole the knot of the cord is placed and
tends to run upwards and inwards thus keeping the cord close to the sash.

COMPLETE SPECIFICATION.
Improvements in and relating to Window Sashes and Frames, and
to other Articles Hung by Weights.
We, ROBERT AMBROSE, and FREDERICK CHARLES AMBROSE, both of 29 Providence
Street, Plymouth, in the County of Devon, Joiners, 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 :-
This invention relates to certain improvements in window sashes and frames
whereby the sashes can be easily and quickly taken out of the frames when it is
required to clean or paint them, to repair broken sash lines, and for other purposes,
the invention being also equally applicable to shutters and other articles hung by
weights. The invention may be adapted to the sashes and frames and the like in
their manufacture, or may be applied to those already in use.
And in order that our invention may be well understood and carried into practice,
we will describe the same with reference to the accompanying drawings in which
similar letters indicate corresponding parts in all the figures.
Figure 1 is a sectional elevation of the inside of a window frame fitted with our
invention; Figure 2 is a section on the line A B Figure 1, the glass of the lower
sash being broken away to shew the pulley style; Figure 3 is part of a view

page_text: similar to Figure 1, but with the lower sash open; and Figure 4 is an enlarged
detail view of one of the pocket pieces.
In fitting window sashes and frames with our invention, we provide the pulley
style of the lower sash with removable pocket pieces CC₁ on to which the parting
bead D D' between the two sashes is rigidly affixed or formed in one with the said
pocket pieces. One of the said removable pocket pieces or is made with the
attached bead D or D₁ in two or more sections hinged or pivotted together....In the
drawings the pocket piece (on the left side of the window frame is shewn as being
made in two sections C and C2 hinged together at E, the attached parting bead being
also in two sections D and D2 meeting when closed at an angle as shewn at E' in
Figure 4. This construction will allow the pocket piece C to be pulled out from the
bottom and turned on the hinge E as shewn by the dotted lines in Figure 1, and by
the full lines in Figure 3, so as to allow the upper section C of the said pocket
piece to be slid down into the space previously occupied by the lower section C until
the upper section is clear of the bottom frame of the lower sash when the pocket
piece may be entirely removed. In Figure 3 the upper section is shewn as having
been partly slid down into the space F previously occupied by the lower section C.
As before stated the pocket piece may be made in more than two sections, each
section being hinged or pivotted to the next, but this will depend on the height as
compared with the width of the window frame. We find however that two sections
are enough for window frames of ordinary dimensions. We prefer to make the
removable pocket piece only slightly longer than the lower sash, commencing at the
sill and terminating say at G Figure 1 or thereabouts, so as to keep the pulley style
as solid and firm as possible.
The pocket piece (" on the other side, i.e. on the right side as shewn in Figure 1,
need not extend more than about three parts of the way from the window sill to
the top of the lower sash, and in some cases the pocket piece on this side
may be made exactly as the other, but this again will depend upon the dimensions
of the window.
To remove the lower sash, throw it up as in Figure 3; catch hold of the parting
bead D and thus pull out the lower section C of the hinged pocket piece; slide
down the upper section C until it can be entirely removed from the space F. Now
pull down the lower sash into its initial position and push it laterally into the space
or groove F previously occupied by the pocket piece. The opposite side of the sash
may now be removed from the window frame and the sash taken out. The parting
bead D having been removed with the pocket piece, the top sash can be similarly
removed by lowering it to the bottom of the frame, pulling it forward and putting it
laterally into the space or groove F.
The styles of the sashes are each provided with a groove nearly its whole length
near the top end of which is a hole bored in a sloping direction to receive a knot
in the line which is to hold the weight; the groove below being to take the loose
line which is left for convenience of raising or lowering the weight when detached
from the sash.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
:-
In the frames of windows, shutters, and other articles hung by weights, on one
side of the said frame, the pocket piece C in two or more sections hinged or pivotted
together with attached bead D, either alone, or in combination with a similar hinged
pocket piece on the opposite side, or with a removable simple pocket piece C¹
substantially as hereinbefore set forth and illustrated in the accompanying drawings,
and for the purpose stated.
