PROVISIONAL SPECIFICATION.
Improvements in Hinged Casement Opening and Closing Mechanism.
I, JOHN HOWARD CARTLAND, of 68, Constitution Hill, in the City of
Birmingham, Brassfounder do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in mechanism for opening and closing
hinged casements in which the primary object is to provide improved means
whereby the fitting shall project as little as possible from the front of the case-
ment and frame, so as not to interfere with blinds, or the like, and also whereby
the fitting may be fixed with very little skill or trouble.
It consists broadly as follows:-A screw rod having a longitudinal movement
is carried in a suitable bracket, which latter is secured to the window frame
at the side of the casement. In this bracket is also carried a grooved pulley
screw nut which may be rotated by means of a cord. The said cord pulley nut
is prevented from endwise movement, so that when rotated the screw rod is
moved inwardly or outwardly as the case may be. The outer end of this rod
is suitably shaped to engage in a curved slot in a bracket which is secured to
the movable casement, the curvature of such slot being made to accommodate
the circular movement (from the hinge) of the casement with the straight
movement of the screw rod.
In some cases this casement bracket is made adjustable so as to accommodate
the varying front levels of frames and casements.
In some cases instead of the rod being screw threaded, it may have teeth
into which may engage the teeth of a worm carried upon or operated by the
cord pulley.
By these means it will be readily seen that no projection stands outwardly
beyond the bracket upon the casement, inasmuch as the rod travels into the
frame, to accommodate which it is only necessary to bore a hole to permit of
the travel of the said rod.

page_text: 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 mechanism for opening and closing
hinged casements, in which the primary object is to provide improved means
whereby the fitting shall project as little as possible from the front of the case-
ment and frame, so as not to interfere with blinds or the like, and also whereby
the fitting may be fixed with very little skill or trouble.
In order to more clearly explain this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference,
similar numbers referring throughout to the same thing or part.
Fig. 1, is a front view, and Fig. 2, a side view of the invention as applied to
a casement hinged at the bottom and opening inwards.
Fig. 3, is a side view, and Fig. 4, a front view of the invention as applied to
a casement hinged at the top and opening outwards.
Fig. 5, is a detailed plan view of the end of the screw rod.
Referring to Figs. 1, 2 and 5. 7, is the casement hinged at 8 to the framing 9.
10, is a screw rod having a longitudinal movement through the bracket 11, which
latter is secured to the framing 9. Between the sides of this bracket is carried
the pulley nut 12, which is grooved to receive the cord 13. The outer end of
this rod 10, is neck shaped at 14, to fit in the curved slot 15, of bracket 16,
which is secured to the movable casement 7, the curvature of the slot 15, being
made to accommodate or compensate the variation arising from the hinged
movement of the screw rod.
Referring to Figs. 3 & 4, it will be seen that in order to open the casement
inwardly, the position of the brackets 11 and 16 is reversed, that is to say the
bracket 11, is now placed upon the casement 7, to which may be added the
tubular shield 17, which forms a protection or cover to the screw rod 10, when
the casement is closed, as it would otherwise stand forward uncovered, on the
exterior side of the casement. The bracket 16, is secured to the framing 9.
In other respects the parts are arranged and operated as described in reference
to Figs. 1 and 2. Any necessary guide rollers or pulleys for the cord 13, may
be added as usual.
In some cases instead of the rod being screw threaded, it may have teeth
into which may engage the teeth of a worm carried upon or operated by the
cord pulley.
By these means it will be readily seen that no projection stands outwardly
beyond the bracket upon the casement, inasmuch as the rod travels into the
frame, to accommodate which it is only necessary to bore a hole in the frame-
work of the window or the casement to permit of the travel of the said rod 10.
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:
1. In hinged casement opening and closing mechanism the combination
comprising the rod 10, operated by cord pulley carried in bracket 11, and neck
extension 14, with curved slotted bracket 16, constructed and operating as set
forth and shown.
