PROVISIONAL SPECIFICATION.
Improvements in Windows and Window Fastenings.
I AMBROSE FERRETT No. 2 Chamberland Cottage, Victoria Road, Pokesdown,
Bournemouth in the County of Hampshire, Carpenter and Joiner do hereby declare
the nature of this invention to be as follows:-
This Invention relates to improvements in windows and window fastenings whereby
the lower window sash may be readily drawn out from the window frame and may be
readily detached from the cords by which it is suspended with counterbalance weights
employed in the usual way. My improvement so far as the window fastening is
concerned relates to the employment of a fastening device which being secured to
the top rail of the lower sash may engage with either the bottom or the top rail of
the upper sash. In this way such a fastening device may be employed for securely
fastening the sashes when both are closed, or for fastening both sashes together when
the lower sash is opened, so that the upper sash may be pulled down by means of the
lower sash, and may be released therefrom to be left open at any required point, or may
be fastened thereto again for the purpose of closing the upper sash as required.
For these purposes I provide running beads to confine the sash having butt hinges
by means of which the running beads may be folded back so as to allow the with-
drawal of the sash when required. The cords by which the sash is suspended are
provided with snaps or spring hooks to engage in eyes fitted in the sash providing for
readily removing the sash entirely from its frame.
The window fastening referred to consists of a spring bolt secured to the top rail of
the lower sash and engaging with either one of two cups fastened one on the bottom
rail and one on the top rail of the upper sash.
This spring bolt may be withdrawn from the cup for unfastening the window or for
disconnecting the two sashes as the case may require by means of a cord or chain
depending therefrom to avoid the necessity of reaching up to the meeting rails of the
sashes.

Improvements in Windows and Window Fastenings.
I AMBROSE FERRETT of 2 Chamberland Cottage, Pokesdown, Bournemouth in the
County of Hants Carpenter and Joiner do hereby declare the nature of this inven-
tion 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 improvements in windows and window fastenings whereby.
the lower window sash may be readily drawn out from the window frame and may be.
easily detached from the cords by which it is suspended with counterbalance weights
in the usual way.
My improvement so far as the window fastening is concerned relates to the
employment of a fastening device which being secured to the top rail of the lower
sash may engage with either the bottom or the top rail of the upper sash. In this
way such a fastening device may be employed for securely fastening the sashes when
both are closed or for fastening both sashes together when the lower sash is opened so
that the upper sash may be pulled down by means of the lower sash and may be

page_text: released therefrom to be left open at any required point, or may be fastened thereto
again for the purpose of closing the uppper sash as required.
For these purposes I provide running beads to confine the sash, having butt-hinges
by means of which the running beads may be folded back so as to allow the with-
drawal of the sash when required.
The cords by which the sash is suspended are provided with snaps or spring hooks
to engage in eyes fitted in the sash providing for readily removing the sash entirely
from its frame.
The window fastening referred to consists of a spring bolt secured to the top rail
of the lower sash and engaging with either one of two cups fastened one on to the
bottom rail and one on the top rail of the upper sash. This spring bolt may be with-
drawn from the cup for unfastening the window or for disconnecting the two sashes
as the case may require by means of a cord or chain depending therefrom to avoid the
necessity of reaching up to the meeting rails of the sashes.
The accompanying drawings will serve to illustrate my invention when the
fastening and lowering device is applied at one side of the sash in a manner which
may be duplicated if desired at the other side of the sash.
In all the figures the same reference letter indicates the same part.
Figure 1 is a side elevation, partly in section of a pair of window sashes shown in
position in the frame.
Figure 2 is a side elevation partly in section and a plan of the spring bolt. Figure 3
is a front view of the plate or cup for receiving the bolt at the upper part of the
upper sash when employed for lowering purposes.
Figure 4 is a front view of the plate or cup for receiving the bolt at the lower
part of the upper sash when employed for fastening purposes. Figure 5 is a side
view of a detaining lever for retaining the spring bolt in its case when required
and a front view of the plate in which this lever is retained in the required
position.
A is the upper sash B is the lower sash C is the cup or plate in which the spring
bolt engages at the upper part of the upper sash having a segmental flange a
extending therefrom to arrest the spring bolt when it arrives at the proper position
for entering the cavity b. D is the cup or plate in which the spring bolt engages
at the lower part of the upper sash the position for entering the cavity c being
determined by closing both the sashes. E is the bolt fitted in a case F from which it
is urged outwardly by the spring G. H is a curved lever fulcrumed at d and con-
nected with the bolt E by a pin or screw e through a slot in the casing F, a stud f
being provided to which is attached a chain or cord for operating the spring bolt
without reaching up to the meeting point of the two sashes.
Instead of employing a chain or cord for this purpose when the spring bolt is
attached at the side of the sash, instead of at the middle, the curved lever H may be
connected by a connecting rod J concealed in the side rail of the lower sash and
connected at its opposite extremity with a lever K by the stud g.
The lever K is fulcrumed at in a casting L in which it is detained in its lowest
position by being urged laterally by the spring j. M is the bead hinged by the butt-
hinges as shown so as to be moved in a position to allow the removal of
the lower sash to be detached from the snaps or spring hooks by which it is
suspended.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination of the bolt E in a casing F with the spring G, the cup or
plate D and the curved operating lever H for fastening window sashes substantially as
described.
2. The combination of the bolt E in a casing F with the spring G, the cup or
plate C and the curved operating lever H with means of operating the same at a low
'

page_text: level for connecting the upper and lower sashes to as to be enabled to employ the
lower sash for drawing down the upper sash substantially as described.
3. The combination of a hinged bead M with a sash suspended by cords fastened
thereto by means of snaps or spring hooks for the purpose of readily removing the
lower sash from its frame substantially as described.
