We, HENRY TOSH, of 197. Buchanan, Street, Glasgow; in, the County of Lanark,
Ironmonger, and SAMUEL PRESTON, of Logan Cottage, Barrhead; in the County
of Renfrew; Clerk of Works, do hereby declare the nature of the said Invention

こ
This Invention relates to improved devices for opening and closing window
sashes and fan lights which are fitted to swivel or swing in their frames.
The improved devices comprise a long screwed spindle which is pivotted to the
fixed framing of the window in close proximity to the opening edge of the movable
Bash, and a grooved pulley fitted to turn thereon as a nut. The pulley is secured
on a swivelling plate pivotted to bracket pieces fixed on the window sash. Over
the pulley is passed a cord or chain by means of which the pulley is turned on the
spindle: The pulley in turning, travels along the screw spindle, drawing with it
the edge of the window frame to which it is secured, and thus opening the window
to any extent that may be desired!

page_text: We, HENRY TOSH, of 197 Buchanan Street, Glasgow, in the county of Lanark,
Ironmonger, and SAMUEL PRESTON, of Logan Cottage; Barrhead in the county of
Renfrew, Clerk of Works, do hereby declare the nature of our said Invention,
for "IMPROVED DEVICES FOR OPENING AND CLOSING WINDOW-SASHES AND FAN-
LIGHTS," 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 improved devices for opening and closing window-
sashes and fan-lights, which are fitted to swivel or swing in their frames.
The invention is illustrated by the accompanying drawings, in which figure 1 is
a perspective view of a modification as applied to a vertical window-sash or- fan-
light, and figure 2 is a similar view showing the improved devices applied to a
roof-light or sky-light Figures 3 and 4 are respectively an end view and a
sectional elevation of the improved opening and closing devices detached.
The improved devices comprise a long screwed spindle A which is pivotted to a
bracket piece B on the fixed framing C of the window in close proximity to the
opening edge of the movable sash D and a grooved pulley E fitted to turn on the
spindle A as a nut. The pulley E is secured on a swivelling plate F pivotted to
bracket pieces G fixed on the window sash D. Over the pulley E is passed a cord
or chain H by means of which the pulley is turned on the spindle A. The pulley E
in turning travels along the screw spindle A, drawing with it the edge of the
window frame D, to which it is secured, and thus opening the window to any
extent that may be desired.
In the case of the skylight illustrated in figure 2, the screwed spindle A is secured
to the movable window sash D, and the bracket G carrying the pulley E is secured
to the stationary frame C.
Figure 5 illustrates a bracket piéce carrying a pair of pulleys, and which is fitted
to the skylight frame for the purpose of guiding the cord H.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, wo declare that what
we claim is,―
The arrangement of the spindle A in combination with the pulley E, the one
"being connected to the window frame and the other to the movable sash, and the
pulley being operated by a cord or chain substantially as herein described and
illustrated.
