page_text: I JOSEPH BRUCE of Gt Colmore Street Birmingham in the County of Warwick
Brass finisher do hereby declare the nature of the said invention for AN IMPROVED
FOR OPENING AND CLOSING CASEMENTS AND VENTILATORS to be as
APPARATUS
follows:-
This invention is applicable to all casements whether hung on centres or hinged,
and to ventilators of the louvre description and consists of attaching to the frame
a metal bracket piece carrying a rotating bar with a screw thread on its surface
upon which travels a block with a guiding piece working in a slot along the
bracket. To the one end of the rotating bar is attached a pulley so that by the
action of an ordinary blind cord over the pulley the bar is rotated and the block
caused to travel up the rod. A lugg upon the block piece works in a slot upon a
plate attached to the casement or ventilator so that the travelling of the block to
and frow causes the casement or ventilator to open and shut. By this arrangement
the casement is always locked whether open or closed.
When it is desired not to
project this bracket too far out a cranked arm is attached to the casement and the
lugg works in a slot thereon.

page_text: I JOSEPH BRUCE of 218 Gt Colmore St Birmingham in the county of Warwick
Brassfounder do hereby declare the nature of my invention for OPENING AND
CLOSING OF CASEMENTS FOR VENTILATION and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:—
This invention is applicable to all casements wether hung on centers or hinged
and to ventilators of the louvre description and consists of attaching to the frame a
metal bracket peice carrying a rotating bar with a screw thread on its surface upon
which travels a block with two guiding peices working in two slots along the
bracket, to the one end of the rotating bar is attached a pulley so that by the
action of an ordinary blind cord over the pulley the bar is rotated and the block
caused to travel up or down the rod, a lug upon the block peice works in a slot
upon a plate attached to the casement or ventilator when opening inwards. When
required to open outwards I attach a jointed arm to the aforesaid lug so that the
block travels in an opposite direction to open casement by this arrangement the
casement's are locked at any angle open or closed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
(1) A slotted bracket A provided with a rotating screwd bar, worked by a
pulley e, on which travels a block with guides and lug B in combination with a
plate, secured to the window with a slot for the lug B to work in, substantially
in the manner and for the purpose herein before described and illustrated.
(2) A slotted bracket A provided with a rotating screwed bar, worked by a
pulley e, on which travels a block with guides and lug B in combination with
a bar D pivotted on lug B and on a plate secured to the window substantially in
the manner and for the purpose herein before described and illustrated.
Dated this 30th day of September 1884.
