COMPLETE SPECIFICATION.
Improved Reversible Sash.
I, JOHN LAMBERT 84 Fleetham Street Middlesboro' 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 and consists in providing a ready means
of cleaning the sashes & also in dispensing with the weights commonly employed
by connecting the two sashes by means of cords or the like passing over pulleys.
Referring to the annexed drawings
Figure 1. is a front elevation showing a window fitted with my invention.
Figure 2 cross section through line x―y.
a is the sash proper which is supported on the screw pivot pin 6 which is carried by
the spring plate c. d is is a tongue or strip having a rebated edge which slides in
grooves in the sash proper a & the styles e so that by raising the tongue d the
sash a is free to be turned on the pivot pin b. f are pulleys attached to the frame
h are the cords which pass over the pulleys & which carry the sashes, a & a¹

page_text: thus dispensing with weights as the sashes balance one another. It will be seen
that owing to the screw pivots the space between the frame and the window sash a
will be closed tight when the sashes are in their closed posit on. By removing
the tongues d the sashes can be rotated on the pivot pins & both sides of the
window be conveniently cleaned.
my
Having now particularly described and ascertained the nature of said
invention & in what manner the same is to be performed I declare that what I
claim is
1. The combination and arrangement of the various parts substantially as
described & illustrated.
2. In window frames of the class herein described in combination, a pulley wheel
over which a cord passes one end being connected to the top & bottom sashes, a
groved tongue piece or slip which engages in a groove on the sash and also in a
groove in the style attached to the cord aforesaid said sash being attached to the
movable style by means of a screw pin attached to a spring substantially as
.described.
