PROVISIONAL SPECIFICATION.
Improvements in or relating to Window Sashes.
I, HENRY JAMES FORD, of 102 Salisbury Road, High Barnet, Gentleman,
do hereby declare the nature of this invention to be as follows:-
This invention relates to window sashes which are usually intended to slide in
their containing frames and it consists in a method or construction by which such
sashes may be so mounted in their frames as to be capable not only of sliding as
aforesaid but also of folding inward when desired principally for the purpose of
cleaning the outside of such windows with convenience.
For this purpose each sash is provided on one side with two or more hinges, the
one leaf of each of which is fixed to the sash and the other leaf forms a runner
engaging in a groove in the window frame, this groove being preferably formed of.
or by two bars of steel or iron fixed to the frame so that the leaf of the hinge runs
in the slot between these bars and is prevented from drawing out by lugs or cross
pins on it engaging behind the bars.
The other side of each sash is provided with one or more sliding bolts which
take into a groove in the corresponding face of the window frame. The sash cord on
the side of the sash where the hinges are, remains fixed to the sash, but the opposite
sash cord which carries the weights which balance the sash on the other side
carrying the sliding bolts is made detachable from the sash for opening the latter
by folding it inwards when desired.
Dated this 1st day of April 1892.

COMPLETE SPECIFICATION.
Improvements in or relating to Window Sashes.
I HENRY JAMES FORD of 102 Salisbury Road, High Barnet, 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 window sashes which are usually intended to slide in
their containing frames and it consists in an improved method or construction by
which such sashes may be so mounted in their frames, as to be capable not only of
sliding as aforesaid but also of folding inward when desired principally for the
purpose of cleaning the outside of such windows with convenience.
For this purpose each sash is provided on one side with two or more hinges the
one leaf of each of which is fixed to the sash style and the other leaf forms a
runner engaging in a groove in the pulley style, this groove being preferably
formed of or by two bars of steel or iron or other metal fixed to the pulley style so
that the leaf of the hinge runs in the slot between these bars, and is prevented
from drawing out by lugs or cross pins on it engaging behind the bars.
The other or opposite sash style is provided with one or more sliding bolts which
take into a groove in the corresponding face of the pulley style. This groove may
also be faced with a bar of steel or iron or other metal on one or each side. The
sash cord carrying the balance weights on the side of the sash where the hinges
are remains fixed to the sash style, but the opposite sash cord which carries the
weights which balance the sash on the other side (carrying the sliding bolts) is
made detachable from the sash for folding the latter inwards when desired.
I DO 1

page_text: The lower or inside sash is made wider than the upper or outside sash and the
metal guides are not fixed in the same plane; the inside guide being set back more
or less according to the thicknesses of the lower sash for allowing the upper sash
to swing inwards parallel with the lower sash when both are swung open for cleaning
or other purposes.
In the annexed drawings
Fig. 1 is a front elevation partly in section of a window frame with two sashes
the lower sash being shown partly raised.
Fig. 2 is a similar view showing the sashes partly swung open.
Fig. 3 is a sectional view on line x Fig. 1 but showing the sashes fully
swung open.
Fig. 4 is a similar section on line y Fig. 1 but showing the sashes closed.
A is the pulley style. B the lower sash. C the upper sash. The one leaf of
the hinges is attached to the sash, the other leaf projects into the slot between
the metal plates a a¹ and is secured by cross pins b. EE are ordinary flush bolts
let into the sash style and projecting when protruded or shot into the groove e of
pulley style to keep the sashes in position and prevent them swinging inward when
not required to be swung open for cleaning or other purposes. ff are the sash
cords, g g the sash weights. At the bottom of each weight box is a concussion
block or buffer conveniently of rubber or felt for use in case the weights fall. The
sash cords on the sides of the window where the bolts E E are, are removably
secured to the sash styles in any convenient way for instance by hook h to engage
with an eye let into the sash style or by a straight pin to be thrust into a hole in
the edge of the sash style. When the sash cord is detached from the sash style it
may be fixed to an eye or hole in the pulley style or frame as in Fig. 2 or thrust
into a socket in the pulley style.
Each guide a a' e extends from the bottom to the top of the pulley style so far
as may be necessary to permit the sash to slide up and down to the full extent.
Before swinging open the sashes the lower is raised to clear the weather bead H
and the bolts EE are drawn back, the lower sash is then swung open slightly
and the sash line detached so that the sash may be fully opened. The upper
sash may then be opened either in its upper position or when it has been drawn
down by similarly drawing back the bolt E and detaching the sash line.
Fig. 2 the sash line of the lower sash alone is shown detached. As the lower
sash is wider than the upper sash the styles of the lower sash are made broader
than those of the upper sash, so that the clear breadth of the light of the sash
may be the same as that of the upper sash.
In
Having now particularly described and ascertained the nature of this 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 bars a a' forming a guide slot in the
pulley style and the hinges D secured to the sash style and guided and secured
in the slot in the manner herein described and illustrated.
2. In a window having a combined swinging and sliding sash supported by
hinges D guided between metal bars a a¹ in the manner described the slot e faced
with metal in combination with the bolts E E and detachable sash cords f¹
substantially as set forth.
