Improvements in the Construction of Window Sashes, and Fittings
and Fastenings for the same.
We, THE SIMPLEX WINDOW FITTINGS COMPANY LIMITED, and PHILIP
DAW, both of 63 Temple Row, in the City of Birmingham, Manufacturers, do
hereby declare the nature of this invention to be as follows:-
Our invention has reference to window sashes in which one sash is employed to
balance the other in the manner set forth in the Specification No. 13973 of 1893,
the object of our present invention being to enable each of the sashes to have their
windows opening into the room so as to obviate the necessity of any external
cleaning and also to provide means of giving a slight amount of opening to the
window either at the top or the bottom without raising or lowering the sashes.
In carrying our invention into effect in one convenient manner, we make the
upper sash with an internal independent sash which we hinge at one side or end
upon the main sash so that when the fastening bolt, buttons, staples or other
devices are released the window may be opened any desired amount without
Instead of
altering the position of the two main sashes within their frames.
hinging the one inner frame to the other we sometimes cause the one hinge frame
to be pivoted centrally within the other in order that the inner frame may be
turned inwards to any extent. both for ventilating purposes and for convenience
iu cleaning. The pivot or pivots upon the inner frame are arranged vertically
within the sash or horizontally as may be most convenient for the particular form
of sash and building to which it is to be applied.
We employ the same system of hinging or pivoting one window or one portion of
the window sash to the other upon the bottom sash as well as upon the top, when it
is desired to provide uniformity in the system of construction and to obviate the
necessity for dividing and hinging a portion of the side frames or bodies of the
frame.
We sometimes manipulate our pivoting or hinging sashes by means of a cord or
rod and we attach side racks or guides with link catches for holding securely the
open window in any desired position.
We make our pivoting or hinging sashes of wood or metal and we provide any
ordinary fastening devices for securing the two sashes together or we arrange a
spring bolt to engage with serrations or a series of holes in a plate carried upon
the side of one of the sashes when it is desired to lock the balanced sashes in
any position when open.
We vary the shape of our sashes and the arrangement of the fittings and
fastenings to suit any particular requirement or any particular type of sash which
is to be employed to suit any style of architecture.

page_text: Improvements in the Construction of Window Sashes, and Fittings
and Fastenings for the same.
We, THE SIMPLEX WINDOW FITTINGS COMPANY LIMITED, and PHILIP
DAW, both of 63 Temple Row in the City of Birmingham, Manufacturers, 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 :--
Our invention has reference to window sashes in which one sash is employed to
balance the other in the manner set forth in the Specification No. 13973 of 1893
the object of our present invention being to enable each of the sashes to have their
windows opening into the room so as to obviate the necessity of any external
cleaning; and also to provide means of giving a slight amount of opening to the
window either at the top or the bottom without raising or lowering the sashes.
In the accompanying sheet of explanatory drawings;
Figure 1 is a sectional side elevation of our improved sashes one sash being open
and the other closed.
Figure 2 is a front elevation of the frame with sashes closed.
Figures 3 and 4 are detail views of our improved hinge.
Figures 5 and 6 show our top sash locking catch in detail.
Figures 7, 8, and 9, show details of our side locking arrangement.
Figures 10 and 11 are details of our chain pulley and pulley plate.
In carrying our invention into effect in one convenient manner we make the
upper sash A with an internal independent sash B which we carry upon pivot
plates CD placed on each side of the frame, or which we hinge at one side or end
upon the main sash so that when the fastening bolt E buttons, staples, or other
devices are released the window may be opened any desired amount within the
limits allowed by the detachable link B' without altering the position of the two
main sashes A within their frames H. Instead of hinging the one inner frame
to the other we sometimes cause the one hinge frame to be pivoted centrally within
the other in order that the inner frame may be turned inwards to any extent both
for ventilating purposes and for convenience in cleaning. The pivot or pivots CD
upon the inner frame are arranged vertically within the sash or horizontally as
may be most convenient for the particular form of sash and building to which it is
to be applied. We make the combination pivot plates C D as shown in Figures 3
and 4 the carrying or face plate D₁ being formed with a projecting shouldered side
flange dagainst which the pivoted sash may bed. We form the pivot C as a
hollow pin which enters into a hollow boss D the attaching screw K. passing
through the hollow centre. We thus take the strain off the screw and provide for
the window to turn freely by the same combination hollow pivot plate. By dis-
connecting the detachable link B' the sash B can be lowered beyond a horizontal
position and brought to rest on the lower sash F.
We employ the same system of hinging or pivoting one window or one portion
of the window sash to the other upon the bottom sash as well as upon the top
when it is desired to provide uniformity in the system of construction. We
sometimes divide the beadh and hinge a portion of the side frames or bodies
of the frame so as to move backwards when the buttons L are released as shown
in Figures 1 and 2.
We may manipulate our hinging or pivoting sashes by means of a cord or rod
and we attach side racks M or guides with catches N for holding the opened
window securely in any desired raised position.
We make our pivoting or binging sashes of wood or metal and we provide
any ordinary fastening devices for securing the two sashes together or we arrange

page_text: the spring bolt N to engage with serrations or a series of holes m in the rack or
plate M carried upon the side of one of the sashes as shown in Figures 7 8 and 9
when it is required to lock the balanced sashes in any position.
=
We make our chain pulley P and plate O as shown in Figures 10 and 11 the
boss O being formed hollow within the plate for the projecting hollow boss P¹
of the pulley to enter, the attaching screw or pin R passes through the hollow
central boss, by this arrangement of plate and boss we take the weight of the
sashes off the pin R.
We vary the shape of our sashes and the arrangement of the fittings and
fastenings to suit any particular requirement or any particular type of sash which
is to be employed to suit any style of architecture.
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 ;-
1. The improvements in self balancing window sashes whereby each sash has an
independent opening and closing motion provided substantially as and for the
purposes hereinbefore described and as illustrated in the accompanying drawings.
2. The improved fittings and fastenings for attachment to self balancing and
independent opening window sashes substantially as and for the purposes herein-
before described and as illustrated.
