Conservatories or similar Places.
I, CHRISTOPHER HENRY METCALFE ALDERSON, of Hilda Vale, Farnborough,
Beckenham, in the County of Kent, Florist, do hereby declare the nature of this
invention to be as follows:-
My invention is an improved apparatus for operating ventilators or windows in
conservatories or similar places. It consists of a pivoted triangular crank and the
necessary attachments thereto, adjusted in such manner as to be operated upon by a
direct pull from a wire, chain, rod or rope; and further, in the arrangement and
operation of the said wire, chain, rod or rope, throughout the said conservatories or
similar places.
The ventilators or windows being hinged on one side in the usual manner, are
opened by my apparatus by tilting or turning on the said hinges.
To effect this, I attach a pivot, stud, or bolt, either to a rafter or any other con-
venient portion of the framework of the building, or to a bracket affixed thereto;
which pivot, stud, or bolt forms a fulcrum upon which the opening mechanism turns.
This opening mechanism consists of a triangular frame (conveniently made of ordinary
iron rod) from one of the lower corners of which, and attached thereto by an eye, I
carry a thrust rod to an eye-bolt fixed in the lower part of the ventilator or window.
The attachments of this thrust rod are approximately equivalent to universal joints,
but I may use universal joints of any other kind. To the third corner of the said
triangular frame, I hinge or pivot a rod, the other end of which I attach by any
convenient means to the said wire, chain, rod or rope; if necessary, the pivotted rod
may be supported in its position, and kept from dropping out of place, by a wire or
cord attached to any fixed point.
The wire, chain, rod, or rope connects the whole or any series of my opening
mechanisms, and is so arranged, that, on being pulled, all or part are opened
simultaneously. The wire, chain, rod or rope may be arranged thus in one of various
ways; as for instance, in the case of the usual arrangement of ventilators on both

page_text: sides of a conservatory, by passing it along one side thereof (beneath the opening
mechanisms to which it is attached by any convenient means), across the end of the
said conservatory, and returning along its opposite side. The two ends of the wire,
chain, rod or rope, may either be attached to each other forming an endless com-
munication, or may terminate at any given point that may be convenient, such
termination being so contrived as to permit the simultaneous opening of the whole or
part of the ventilators or windows as hereinbefore described. Any necessary turn,
bend, or change of direction in the wire, chain, rod or rope, may be readily effected
by the use of suitable cranks, pulleys or other mechanical means.
The wire, chain, rod or rope may be securely fixed at any required position by
means of cleats or their equivalents, or, if endless, by a catch or other fastening.
In order to facilitate the opening of the ventilators or windows, a counter-balancing
weight may be attached to the vertical portion of the wire, chain, rod or rope.

page_text: An Improved Apparatus for Operating Ventilators or Sashes in
Conservatories or similar Places.
I, CHRISTOPHER HENRY METCALFE ALDERSON of Hilda Vale, Farnborough,
Beckenham, in the County of Kent, Florist, do hereby declare the nature of this
invention and in what inanner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention is an improved apparatus for operating ventilators or windows in
conservatories or similar places. It consists of a pivoted triangular crank and the
necessary attachments thereto, adjusted in such manner as to be operated upon by a
direct pull from a wire, chain, rod or rope; and further in the arrangement and
operation of the said wire, chain, rod or rope throughout the said conservatories or
similar places.
The ventilators or windows being hinged on one side in the usual manner are
operated by my apparatus by tilting or turning on the said hinge. To effect this I
attach a pivot, stud, or bolt, either to a rafter or any other convenient portion of the
framework of the building, or to a bracket affixed thereto; which pivot, stud, or bolt
forms a fulcrum upon which the opening mechanism turns. This opening mechanism
consists of a triangular frame (conveniently made of ordinary iron rod) from one of
the lower corners of which, and attached thereto by an eye, I carry a thrust rod to an
eye-bolt fixed in the lower part of the ventilator or window.
The attachments of this thrust rod are approximately equivalent to universal joints,
but I may use universal joints of any other kind. To the third corner of the said
triangular frame, I hinge or pivot a rod, the other end of which, I attach by any
convenient means to the said wire, chain, rod or rope; if necessary, the pivotted rod
may be supported in its position and kept from dropping out of place by a wire or
cord attached to any fixed point.
The wire, chain, rod or rope connects the whole or any series of my opening
mechanisms and is so arranged, that, on being pulled, all or part are opened
simultaneously. The wire, chain, rod or rope may be arranged thus in one of various
ways, as for instance, in the case of the usual arrangement of ventilators on both sides
of a conservatory, by passing it along one side thereof (beneath the opening mechanisms
to which it is attached by any convenient means) across the end of the said con-
servatory and returning along its opposite side. The two ends of the wire, chain, rod
or rope, may either be attached to each other forming an endless communication, or
may terminate at any given point, that may be convenient, such termination being so
contrived as to permit the simultaneous opening of the whole or part of the ventilators
or windows as hereinbefore described. Any necessary turn, bend or change of direction
in the wire, chain, rod or rope, may be readily effected by the use of suitable cranks,
pulleys or other mechanical means.
The wire, chain, rod or rope may be securely fixed at any required position by
means of cleats or their equivalents, or, if endless, by a catch or other fastening. In

page_text: order to facilitate the opening of the ventilators or windows a counterbalancing weight
may be attached to the vertical portion of the wire, chain, rod or rope.
In order that my invention may be the better understood,
same in the accompanying sheets of drawings in which :-
now proceed to illustrate
Figure 1 is a front and Figure 2 is a side elevation of one of my triangular lifting
frames.
Figure 3 shows a portion of a system.
Like letters refer to like parts throughout the figures, in which :-
A are the triangular frames each pivotted to a support B engaging with the ridge
of the house; the frame is pivotted to a thrust rod C, which engages with the
ventilator or sash D. It is also pivotted at E to a rod fixed to the communicating or
operating cord F. This cord, in communication with a series of lifting frames,
conveniently passes over a pulley, and is operated by means of a suitable crank G or
other similar device. It is also conveniently provided with a counterpoise H and a
stop mechanism K, of any suitable kind, such as a cam on a handle jamming the cord,
or a ratchet and spring pressed pawl.
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 :-
1st. In apparatus for the operation of ventilators or sashes, the combination of a
lifting frame pivotted to the building and communicating by means of a thrust rod
with the ventilators or sashes and operated through a pivotted rod by means of a
continuous wire, rod, chain or rope, substantially as and for the purposes specified.
2nd. The combination with such a device of a crank, or other operating mechanism,
counterpoise, and suitable stop apparatus, substantially as and for the purposes
specified.
