PROVISIONAL SPECIFICATION.
Improvements in and connected with Sliding Sash Windows and
analogous Casements.
I, JAMES BARTON, of 3 Braid Street, in the County of the City of Glasgow,
North Britain, Joiner, do hereby declare the nature of this invention to be as
follows:-
-
This invention, which relates to improvements in and connected with sliding
sash windows and analogous casements, has for its object to convert the sliding
action of such windows or casements into a pivotal or hinge action after the
manner of French windows in order to facilitate the cleaning of the outside of the
said windows or casements from within the room, chamber or apartment in which
they are placed.
The invention, whereby this end is.attained consists in fitting to the framework
of the window or casement, corresponding to the lower sash, a pair of hinges of
somewhat novel form or configuration, placed at suitable distances apart from each
other.
One half of each of the said pair of hinges (preferably "butt" hinges) is
bent to such an angle that the portion of the plate in which the counter sink
holes are usually made to enable it to be fixed in position, is at right angles to
the remaining unbent portion of the said half of the hinge containing the pin
joint.
The said bent portion of the hinge is fixed on the outside of the groove or
recess of the framework constituting the part where the sliding action of the
window sashes takes place.
The unbent portion of the said hinge, by virtue of its construction, is flush
with the rear portion of the bead rail, and, consequently lies in alignment
with the sash of the window. The pin joint projecting somewhat beyond the
bead rail.
The surface of both the recess and the back side of the bead rail is recessed to
receive the bent portion of the hinge last described.
The other member or plate of the hinge, not previously referred to, being of
somewhat smaller dimensions and capable of free axial motion, is provided with a
tongue projecting upwards.
Mounted on the stile of the window sash are two metal plates corresponding in
position to that of the said pair of hinges. The body part of each of the said
plates is of hollow' or box configuration, having a rectangular, vertical opening or
cut formed on its lower side. When the free end of the said hinge is turned in a
certain position, that is to say, when it lies against the stile of the window sash,
the tongue formed upon it, will be ready to enter, and indeed does, engage the
rectangular opening formed in the body of the plate above mentioned, the sash
being drawn down the required distance. It being understood that the lower sash
has been previously raised clear of the beading formed at the bottom of the
window to allow this operation being performed.
The free ends of the pair of hinges, the cord at the opposite side of the window
being disconnected, then carry the weight of the bottom sash which is capable of
being turned the required distance to enable the window. being cleaned.
...

page_text: When it is desired to convert the top sash into a pivotal or axial motion a pair
of hinges is also employed and fitted in position on or near the parting trail in a
manner similar to that already described with reference to the lower sash. It
being explained that the metal plates are also comprised in this last mentioned
arrangement.

Improvements in and connected with Sliding Sash Windows and
analogous Casements.
I, JAMES BARTON of 3 Braid Street, in the County of the City of Glasgow,
North Britain Joiner 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 which relates to improvements' in and connected with shiding sash
windows and analogous casements has for its object to convert the sliding action of
such windows or casements into a pivotal or hinge action after the manner of
French, windows in order to facilitate the cleaning of the outside of the said
window's or casements from within the room, chamber or apartment in which'-they
are placed.
•
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings in 'the several
figures of which corresponding parts are marked with the same letters of reference."
Figure 1 is'a front elevation of a window made in accordance with and c
- constituting
my said invention.
Figures 2 and 3 are respectively side elevation and plan of the hinge of novel
construction' with which the said window is fitted!
Figures 4 and 5 are also 'side elevation and plan of the plate receptacle hereinafter
more fully referred to.
Figure 6 is a
part plan and part' horizontal' section of part of a window
illustrating the two sashes converted from the sliding into a hinge or pivotal action
and hereafter more fully referred to.
pair of
The invention whereby this end is attained consists in fitting to the framework
of the window or casement A; corresponding to the lower sash Ba
hinges C, of somewhat novel' form or configuration pláced' at suitable distances
apart from each other.
One half of each of the said pair of hinges C, (preferably butt hinges) is bent
to such an angle that the portion of the plate C', in which the counter-sink holes
are usually made to enable it' to be fixed in' position is at right angles to the
remaining unbent portion C², of the said half of the hinge containing the pin joint
as seen in Fig. 3. The said bent portion of the hinge C, is fixed on the 'outside
of the groove or recess D, of the framework (known as the pulley stile).
+
The unbent portion C3, of the said binge C, by virtue of its construction, is
flush with the rear portion of the bead rail D, and consequently lies in alignment
with the sash' of the window as seen in Figures 3 and 6. The pin' joint projecting
somewhat beyond the bead-rail a's see more particularly in Figure 6.
The surface of both the recess D and the back side of the bead rail D¹ is
recessed to receive the bent portion of the hinge last' described!
The other member or plate C³, of the hinge C, not previously referred to, being
of 'somewhat smaller dimensions and capable of free axial motion, is provided' with
a tongue C, projecting upwards seen in Figures 1 and 2.

page_text: Mounted on the stile of the window sash are two metal plates E, corresponding
in position to that of the said pair of hinges already referred to. The body part of
each of the said plates E is of hollow or box configuration, having a rectangular,
vertical opening or cut F, formed on its lower end, as seen in Figs. 4 and 5. When
the free end of the said hinge is turned in a certain position such as that shewn in
Figures 2 and 3 that is to say, when it lies against the stile of the window sash, the
tongue C, formed upon it, will be ready to enter and indeed does engage the
rectangular opening F formed in the body of the plate E before mentioned,
the sash being previously raised and drawn down the required distance. Such a
position is seen in dotted lines Figure 1. It being understood that the lower sash
has been previously raised clear of the beading G, formed at the bottom of the
window to allow this operation being performed. The free ends C³ of the pair of
hinges, (the cord at the opposite side of the window being disconnected) then
carry the weight of the bottom sash which is capable of being opened pivotally the
required distance to enable the window being cleaned.
When it is required to convert the top sash into a pivotal or axial motion a pair
of hinges C and plate receptacles E¹, are also employed, and fitted in position on
or near the parting rail D2, in a manner similar to that already described with
reference to the lower sash B.
The arrangement and construction of the upper sash will be the better under-
stood reference being had to Figure 6.
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 hinge C constructed as described and fitted on to the pulley stile-
preferably two to each sash-of a sliding sash window substantially as and for the
purposes hereinbefore described.
2. In combination with the hinge C, the plate receptacle E, having a rectangular
vertical receptacle or opening F, for engaging with the tongue C of the said
hinge C, whereby the sliding action of the window is converted into a hinge or
pivotal action substantially as and for the purposes hereinbefore described.
3. The general arrangement and combination of parts operating substantially as
and for the purposes hereinbefore described and shown on the accompanying sheet
of drawings.
