IMPROVEMENTS IN APPARATUS FOR OPENING AND CLOSING SWING SASHES SHUTTERS AND DOORS
Year: 1884

page_text: I GEORGE PAINE of Broadwater Worthing in the County of Sussex Machinist
do hereby declare the nature of said invention for IMPROVEMENTS IN APPARATUS
FOR OPENING AND CLOSING SWING SASHES SHUTTERS AND DOORS, to be as
follows:-
The improvements consist of an excentric counter balance weight applied to a
rod or rods fastened or hinged to the swinging sash, shutter or door, one such
weight may be supplied to each rod, or may counterbalance a series of such rods
which in such case are fixed to a main rod and to this main rod the counterbalance
weight or weights are fixed, when several sashes are opened and shut in this
manner I place a wheel or lever arrangement on the main rod and by it actuate
the subsidiary rods and sashes &c. The counter balance may be proportioned to
give any desired opening-The object is to have a simpler opener and fastener,
consisting of few pieces.

page_text: I, GEORGE PAINE, of Broadwater, Worthing, in the County of Sussex, Machinist,
do hereby declare the nature of my invention for IMPROVEMENTS IN APPARATUS
FOR OPENING AND CLOSING SWING SASHES, SHUTTERS, AND DOORS, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
The improvements consist of an excentric lever, and counter balance weight
applied to a rod or rods fastened or hinged to the swinging sash, shutter or door,
one such weight may be supplied to the excentric lever or to each rod, or may
counterbalance a series of such rods which in such case are fixed to a main rod and
to this main rod the counter balance weight or weights are fixed, when several
sashes are opened and shut in this manner I place a toothed wheel on the main rod
and by it actuate the subsidiary rods and sashes &°. The counterbalance may be
proportioned to give any desired opening. The object is to have a simpler opener
and fastener, consisting of few pieces.
The accompanying drawing will show further how the invention may be
performed like letters representing like or corresponding parts in all the figures.
Fig 1 is a longitudinal side view of a conservatory. Fig 3 cross section of same.
Fig 2 plan, having the improvements applied. A is the excentric lever and X the
counterbalance weight. B the rod connecting A with the sash C, said rod being
pivoted at each end as shown, D is a main rod on which the lever A and counter-
balances X are fixed or keyed-the rod D when several sashes are to be opened
and shut is worked by a convenient wheel or lever arrangement turning a rcd
carrying a worm gearing in a worm wheel as shown. Fig 4 shows cross section of
roof of a conservatory and the apparatus arranged for operating the sashes when
used in that position.
In some cases the counterbalance weight and the excentric lever may be made in
one piece.
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 :-
The apparatus consisting of the excentric lever A counterbalance weight X and
pivoted rod B-mounted as shown and operated for the purposes of opening or
shutting sashes shutters or doors, substantially as described and illustrated.
