PROVISIONAL SPECIFICATION.
Improvements in Means for Opening and Closing Windows,
Ventilators, and the like.
We, CHARLES EDWARD BATCOCK and JOHN HENRY KENYON both of
3 Watcombe Terrace High Street, Ponders End, Middlesex, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in means for opening and closing windows,
ventilators and the like and consists in an improved arrangement of the levers and
their connection to the window, ventilator or the like, and the same is carried out
as follows:-
We employ a main pivoted lever either in one or more parts, one end being
connected to a sliding rod by means of a pivoted rod or bar; the other end being
connected to the window, ventilator or the like through the medium of a rod,
attached to the window, ventilator or the like; a small wheel or pulley being
carried at the end of the main lever and running upon the said rod; a. guard rod
being provided to prevent the window, ventilator or the like from having
independent movement from the lever aforesaid. Any well known convenient
arrangement such as a rack and lever may be employed to operate the sliding rod.
If desired instead of a pivoted lever, I may employ a chain passing over a pulley
and having a guard or pulley to maintain same in position.

Improvements in Means for Opening and Closing Windows,
Ventilators, and the like.
We, CHARLES EDWARD BATCOCK and JOHN HENRY KENYON Durants'
Harbour Ponders End Middlesex Engineers, 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 improvements in means for opening and closing windows,
ventilators and the like and consists in an improved arrangement of the levers and
their connection to the window, ventilators or the like, and the same is carried out
as follows:-
We employ a main pivoted lever either in one or more parts, one end being
connected to a sliding rod by means of a pivoted rod or bar; the other end being
connected to the window, ventilator or the like through the medium of a rod
attached to the window, ventilator or the like, a small wheel or pulley being
carried at the end of the main lever and running upon the said rod; a guard rod

-arrangement such as a rack and lever may be employed to operate the sliding rod.

a is the window or ventilator upon which the rail or bar bis secured. The
lever is provided with a small wheel or pulley e which runs upon the rail or bar b,
d being a guard which prevents the rail from leaving the wheel or pulley e and
also prevents the window or ventilator being blown open by the wind so that the
window or ventilator is secured in the desired position. is the pivot or support
upon which the levers c & d¹ turp said two levers-c & d being secured or rivetted
.at h.
The rod is pivoted at j, to the lever d' which is pivotally attached at k, to the
rod or bar which is supported in suitable. bearings and by moving the rod or bar
in the direction of the arrow 1, which will cause the window.or ventilator a to be
raised, the hinges for which will be situated at the end a¹ of the window or
ventilator.
In Figure 2, the lever m, is secured or rivetted at n to the lever o, which are
again secured together by the bar p, which is rivetted at g, and r, to the levers m,
and o. The lever m, is again carried upon the pivot or support f.
In Figure 3, the pivot f, is formed with the plate s, which may be attached to or
formed integrally with the screw pin or bolt which has a square or other suitable
shaped head t in order that the same may be driven or screwed into the wood work
or other support u. Of course it will be seen that the pivot may be secured in
position by any well known or suitable means, but I prefer that shown in
Figure 3.
The dotted lines in Figure 1. show the position of the levers when the window or
ventilator is opened or raised.
Any convenient or well known arrangement of mechanism such as a rock and
pinion may be employed to operate the rod or bar l, or if desired a cord may be
attached to the end v, of the rod i and passed over a pulley or the like so that the
lever i, may be operated.
Any required number of the arrangement of levers shown in Figures 1 & 2 may
be operated by the rod or bar mechanism, for the purpose of opening windows or
ventilators.
When desired a suitable form of catch may be employed to secure the window or
ventilator in its closed position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be carried out we declare that what
we claim is:
1. The combined construction and arrangement of the various parts substantially
as described and illustrated herein.
2. In means for opening or closing windows ventilators and the like; a pulley
which bears upon a rod or rail secured to the window, ventilator or the like and
having a guard for maintaining said rod or rail in position upon the pulley; said
pulley and guard being carried upon the end of the opening or closing lever
substantially as described and illustrated.
