Improvements in or relating to Sliding and Swinging Window
Sashes and Frames therefor.
I, HENRY JAMES FORD of 29 Lichfield Grove, Church End, Finchley, N. in
the County of Middlesex Gentleman do hereby declare the nature of this invention
to be as follows:-
This invention relates to that class of window sashes which, while usually
intended to slide in their frames, are also so fitted that they may be swung about
one of their side edges when desired for instance for greater convenience of
cleaning or for passing large articles of furniture into or out of the room by
way of the window.
The objects of the present invention are principally to provide for the movement
of the sashes in either way without making one of the sashes of less width
than the other and without altering the general appearance of the sashes or of
the frame, further objects being to simplify the construction, to render it more
easily attained, to render the metal work required more efficient and more easily
fixed and also, as an incidental advantage, to give easy access to the counterbalance
weights of the sashes for the renovation of the sash lines or other purpose.
The sashes are each provided on one side edge with hinges, the improved
hinges being made with a flanged rib along the back of the leaf which is hinged
to the leaf on the sash, so that this rib may ride in the groove provided therefor
in the side of the window frame and the flange or flanges on the rib may engage
behind the plates which face the said groove to hold the rib from falling out of the
groove.
The inside face linings are made removable from their lower ends or near
thereto for a distance so far as may be necessary to enable the lower sash to be
freely swung inwards, and this construction in connexion with the improved method
of hinging the sash enables the latter to be swung through an angle equal to
180° or near thereto, so that the upper sash when drawn down may also be
swung open through 90° or nearly so (sufficiently that is to say for cleaning the
outside or giving a clear passage through the window) even when the face plates
of the upper and lower sash grooves respectively lie both in the same plane as
they are enabled to do by this method, thus allowing both sashes to be of the same
width.
The parting beads are also made removable from their lower ends or near
thereto, so far as may be necessary to allow the upper sash, after it has been
drawn down, to be swung inward in the manner previously described.
In place of making the metal face plates of the side grooves out of two separate
and distinct pieces requiring to be separately fixed and adjusted, the necessary
grooved may be made in one piece of metal, cast or made for the purpose, or
in two or more such parts but so made that by the abutting of one part against
the other in fixing the necessary width and dimensions of the groove are attained
without special attention to that end.
The removable parts of the parting beadings and of the inside face linings may
be fixed in place in any convenient manner for instance by scarfing or tongueiug
one end and fixing the other end by a recessed or other sliding bolt or other
fastener.
The sashes may both be hinged on the same side of the window, or each on
different sides.

page_text: The removable nature of the lower part of the inside face linings allows access
to be had to the sash weights.
Suitable ornamental metal work or other work may be used to hide the meeting
line between the removable and stationary parts of the face linings. The beading
on the inner edge of the face lining is removeably therewith so far as necessary.
This invention may be applied without difficulty to sliding sashes and frames
already in use.
With this invention no sliding bolts are required on the outer swinging edge of
the sash, nor any metal faced or other grooves therefor.

COMPLETE SPECIFICATION.
Improvements in or relating to Sliding and Swinging Window
Sashes and Frames therefor.
I, HENRY JAMES FORD of 29 Lichfield Grove, Church End, Finchley N. in
the County of Middlesex, Gentleman, 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 that class of window sashes which, while usually
intended to slide in their frames, are also so fitted, that they may be swung about
one of their side edges when desired; for instance, for greater convenience of
cleaning or for passing large articles of furniture into or out of the room by way of
the window.
The objects of the present invention are principally to provide for the movement
of the sashes in either way without making one of the sashes of less width than the
other and without altering the general appearance of the sashes or of the frame,
further objects being to simplify the construction, to render it more easily attained,
to render the metal work required more efficient and more easily fixed and also, as
an incidental advantage, to give easy access to the counterbalance weights of the
sashes for the renovation of the sash lines, or other purpose.
The sashes are each provided on one side edge with hinges, the improved hinges
being made with a flanged rib along the back of the leaf which is jointed to the leaf
on the sash, so that this rib may ride in the groove provided therefor in the pulley
style of the window frame and the flange or flanges on the rib may engage behind
the plates which face the said groove to hold the rib from falling out of the
groove.
The inside face linings are made removable from their lower ends or near thereto
for a distance so far as may be necessary to enable the lower sash to be freely swung
inwards, and this construction in connection with the improved method of hinging
the sash enables the latter to be swung through an angle equal to 180° or near
thereto, so that the upper sash when drawn down may also be swung open
through 90° or nearly so (sufficiently that is to say for cleaning the outside or
giving a clear passage through the window) even when the face plates of the upper
and lower sash grooves respectively lie both in the same plane as they are enabled
to do by this method, thus allowing both sashes to be of the same width; or the
hinges fixed to the bottom sash may each be preferably provided with an extra
leaf acting as three-leaf extension hinges, carrying the sash fully back through the
same angle and permitting the essence of the invention to be observed without
altering the usual form of construction of the inside face linings.
The parting beads are also made removable from their lower ends or near thereto
so far as may be necessary to allow the upper sash, after it has been drawn down,
to be swung inward in the manner previously described.
In place of making the metal face plates of the side grooves out of two separate

page_text: and distinct pieces requiring to be separately fixed and adjusted, the necessary
grooves may be made in one piece of metal forming a boxing, cast or made for
the purpose, or in two or more such parts but so made that by the abutting of one
part against the other-in fixing, the necessary width and dimensions of the groove
are attained without special attention to that end.
The removable parts of the parting beadings and of the inside face linings may
be fixed in place in any convenient manner for instance by stub at the lower end
and plate in the sill and locking plate at the upper end and hasp on the fixed
portion of the inside linings and parting beads.
The sashes may both be hinged on the same side of the window, or each on
different sides.
The removable nature of the lower part of the inside face linings allows access
to be had to the sash weights.
Suitable ornamental metal work or other work may be used to hide the meeting
line between the removable and stationary parts of the face linings, the beading on
the inner edge of the face lining is removable therewith so far as may be necessary
and is grooved out on the hinges side to take the knuckles of the hinges fixed to
the bottom sash which project into the front beading.
This invention may be applied without difficulty to sliding sashes and frames
already in use.
With this invention no sliding bolts are required on the outer swinging edge of
the sash, nor any metal faced or other grooves therefor.
In the annexed drawings,
Fig. 1, shews the portion of the inside face linings and parting beadings removed
to enable the sashes to swing; also, the counterbalance weights J exposed for
renovation of the sash lines.
Fig. 2, shews details of the hinges C and D ; also, vertical metal boxing E set
in the pulley style I ; likewise, front beading H grooved out to take the projecting
knuckles of the hinges D fixed to the bottom sash.
Fig. 3, shews stub, which is fixed to the end of the removable part of each
inside face lining; also, corresponding reception plate, which is fixed to the sill.
Fig. 4, shews locking plate which is fixed to the top of the removable part of
each inside face lining; also, corresponding hasp, which is fixed to the lower end
of the stationary part of each inside face lining.
A is the lower sash, B the upper sash. The one leaf of the hinges C, Fig. 2,
is fixed to the top sash and the one leaf of the hinges D, Figs. 1 and 2, is fixed to
the bottom sash, the rib on the other leaf of each of which rides in the slot between
the face plates of the metal boxing E, Fig. 2, and is secured from falling out by the
flange on either side of the rib engaging behind the said face plates of the metal
boxing.
Each metal boxing extends in the pulley style I, Figs. 1 and 2, to a height so
far as may be necessary to hold the sash in its upright position when the latter is
swung inwards, and the pulley styles are grooved out to take the flanges of
the hinges fixed to the sashes to allow them to slide up and down to their full
extent.
Before swinging open the sashes, the lower is raised to clear the bottom beading,
the removable portion of the inside face linings and front beadings are removed by
unbasping the locking plate, see F, Figs. 1 and 4, and lifting the stub out of plate,
see Fig. 3.
After disconnecting the sash cord on the edge of the sash opposite to the hinges
side, the lower sash A, Figs. 1 and 2, is swung well back.
The lower portions of the parting beadings are next taken away and, after
having drawn down the top sash to the bottom of the frame (that is, clear of the
stationary upper portion of the inside face linings and parting beads, see G, Fig. 1)
and disconnected the sash cord, it (the top sash) B, Figs. 1 and 2, can then also be
swung inward.

page_text: 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. In a window having a combined swinging and sliding sash the combination
with the sash and pulley style of the metal boxing E forming a guide slot in the
pulley style and the hinges C and D secured to the sash style and guided and
secured in the metal boxing in the manner herein described and illustrated.
2. In a window having a combined swinging and sliding sash supported by
hinges C or D guided in metal boxing E in the manner described and illustrated
in combination with the removable nature and portion of the inside face linings
and beadings secured by metal stub and plate, Fig. 3, and hasp and locking plate
Fig. 4 substantially as set forth.
