PROVISIONAL SPECIFICATION.
Improvements in Casement Opening, Closing, and Securing
Mechanism.
I JOSEPH LILLY, of 6 Hutton Street, Nechells, in the County of Warwick,
Art Metal Worker, do hereby declare the nature of this invention to be as
follows:
This invention 'relates to improvements in the combination and arrangement of
parts constituting mechanism employed for the opening, closing and securing of
inovable casements such as are carried at their one end or side by hinges, or upon
pivots.
It consists in the combination of a lever grip, and home catch fastening with a
flexible adjustment cord or chain acting with the said grip mechanism and a roller
motion, and having further an operating cord.
Upon the fixed framing a bracket is secured to which the one end of a stout
cord or other flexible rod or chain is attached. Upon this bracket is further
carried an outstanding hook like catch having at its underside an inclined surface
leading to its catch part.
Upon the movable casement is a second bracket carrying an eccentric lever
grip; the one (outer) end of this lever being heavily weighted, whilst its inner
end is shaped to form the counterpart of the hook catch upon the first named
bracket; and also to such inner end is attached the opening manipulating cord.
The closing manipulating cord consists of the flexible cord or chain whose one end
is secured to the first named bracket (as before described).
Preferably for convenience the outer ends of these two cords are connected
together. Carried also upon the casement bracket and below the eccentric grip is
a roller, between which and the grip the adjusting and closing cord passes.
Its action is therefore as follows: Upon pulling the opening cord the catch portion
of the eccentric grip lever is first released from the book portion of the fixed bracket,
then by continuation of pull, the casement may be opened to any desired extent,
the flexible cord being allowed to freely pass between the eccentric grip and the
roller, because the act of pulling the opening cord lifts or turns the eccentric free of
the adjustment cord. Upon letting go the opening cord the heavily weighted end of
the grip lever falls and the eccentric seizes the adjustment cord and prevents
further opening. By pulling down the adjusting cord (which rides upon the roller)
the tendency of the said pull is to free the eccentric therefrom, and thereby the
casement is closed.
Having reached its closed position, the catch part upon the casement bracket
passes underneath the hook portion upon the frame bracket, and the casement is
perfectly locked and secure.

Improvements in Casement Opening, Closing, and Securing
Mechanism.
I JOSEPH LILLY of 6 Hutton Street, Nechells, in the County of Warwick,
Art Metal Worker, 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 the combination and arrangement of
parts constituting mechanism employed for the opening, closing and securing of
movable casements, such as are carried at their one end or side by hinges or upon
pivots.
It consists in the combination of a lever grip, and home catch fastening with a
flexible adjustment cord or chain acting with the said grip mechanism and a roller
motion, and having further an operating cord.
In order to more clearly explain this my said invention, I have appended
hereunto an illustrative sheet of drawings, upon which are figures and numbers
of reference, similar numbers referring throughout the several views to the samė
thing or part.
Fig. 1, is a side view of the invention as it appears when the casement is closed
and secured.
Fig. 2, is a side view of the invention showing the casement in the act of being
opened.
Fig. 3, is a view of the mechanism as it appears when the casement has been
opened to any required position and there secured by the gripping device.
Fig. 4, is a detailed sectional view showing a modification in lieu of the roller
before mentioned.
Fig. 5, is a detailed front view of the lever.
Fig. 6, is a detailed front view of the fixed bracket upon the casement framing..
Fig. 7, is a detailed front view of the casement bracket.
Upon the fixed framing 8, a bracket 9, is secured to which the one end of the
chain 10, is attached. . If desired a stout. cord or other flexible rod may be used
but the chain is preferred. Upon this bracket 9, is further carried an outstanding
hook like catch 11; having at its underside an inclined surface 12, leading to its
catch part 13.
Upon the movable casement 14, is a second bracket 15, carrying the lever 16,
pivoted at 17, and having the eccentric like gripping part at 18. The one (outer)
end 19, of this lever being heavily weighted, whilst its inner end is shaped to form
the latch 20, or counterpart of the hook catch 13 upon the first named bracket;
and also to such inner end of the lever is attached at 21, the opening manipulating
cord 22. The closing manipulating cord 23, consists of an extension of the flexible
cord or chain 10.
Preferably for convenience the outer ends of these two cords 22 and 23 are
connected together. Carried also upon the casement bracket 15, is a roller 24,
pivoted at 25, between which and the grip the adjusting and closing cord passes.
In some cases I prefer to dispense with the roller 24, and provide in its stead the
fixed bridge plate 24", see Fig. 4.
-
Its action is now therefore as follows Upon pulling the opening cord 22, the
latch portion 20, of the eccentric grip lever is first released from the hook portion 13,
of the fixed bracket, by reason of its being turned about its centre 17, (such a
position of lever is shown in Fig. 2); then by a continuation of pulling the cord 22,
the casement 14, may be opened to any desired extent, the chain being allowed to
freely pass between the eccentric grip and the roller 24, or plate 24, as the case
may be, because the act of pulling the opening cord 22, lifts or turns the lever 16,

page_text: so that the gripping part 18, is quite free of the chain 10. Upon letting go the
opening cord 22, the heavily weighted end 19, of the grip lever falls, and the
eccentric grip 18, seizes the chain and prevents further opening, as shown in
Figs. 1, 3 & 4. By pulling down the chain 10 or cord 23 (which rides upon the
roller 24 or plate 24), the tendency of the said pull is to free the eccentric
therefrom, by reason of the grip part 18, being a little below the centre 17, and
thereby the casement is closed.
Having reached its closed position, the catch part 20, upon the lever 16 carried
upon the casement bracket, passes underneath the hook portion 12, upon the
frame bracket, and the casement is perfectly locked and secured as shown in
Figs. 1 & 4.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
In opening and closing mechanism for movable casements the combination with
the flexible chain 10, bracket 9, having the hook 11, with catch parts 12, and 13,
of the pivoted lever 16, having the grip 18, and latch part 20, parts 24 or 24,
and operating cord 22, substantially as described and shown and for the purposes
specified.
Dated this 26th day of April 1894.
