Improvements in Mechanism for Opening, Closing, and Securing
Moveable Casements and other similar Structures.
I HENRY STANHOPE OWENS of Ferne Lea, Greenhill Road, Moseley Birmingham,
in the county of Worcester Brassfounder do hereby declare the nature of this
invention to be as follows:-
This invention relates to the construction and arrangement of parts constituting
mechanism whereby casements, skylights, or other similar hinged structures, may
be adjustably opened or closed, or held securely when closed; and its object is to
provide, that the upper end of the operating rod which is either formed into a slide,
or attached to a slide, shall travel in a slide guide, such guide being also in most cases
of peculiar construction, the said slide communicating motion to the said casement
by means of a hinged arm or link, the outer end of which is secured to a bracket or
fitting upon the casement; that the operating rod shall at its lower end be actuated
by means of bevil gearing carried within a box of special construction, one of the
said wheels serving as a screw nut, working upon a screw thread formed on the said
rod. This mechanism may be applied to the opening of casements opening inwards
or outwards.
As applied to a casement hinged at the bottom and opening inwards, for instance,
its construction and arrangement would be somewhat thus:-
Upon the casement frame, and at the side of the upper part of the casement, I
provide a slide guide or channel.
This guide construct preferably thus:-1 draw a piece of metal into a part tubular
form, that is, forming a base, the two sides, and an overhanging top upon each side,
leaving a continuous central slot or opening along its top. At the one, upper end is
fixed a stop piece. In the said base part are made the screw down holes which are
readily accessible, through the open slot.
Working in this guide is a slide, to which is attached the upper end of an operating
rod, or, if desired, the upper end of the said rod itself may be shaped to so form
the slide.
The other
Upon this slide a joint is made to receive the one end of a link or arm.
end of this arm or link is further jointed to a bracket or other fitting upon the
moveable casement, at a point about opposite the lowest working position of the
aforesaid slide.
Again. At the lower end of the aforesaid operating rod which extends down
the side of the window &c., it is screwthreaded, and at such part, a gearing box
(through which the said screw passes), secured to the casement frame or
fixture.
Within this box is provided a bevil wheel nut, working upon the said screw, and
also at the inner front part of the said box, is a second (horizontal) bevil wheel,
gearing thereinto. Opposite to the centre of the horizontal bevil wheel, is provided a
fixed bracket, between which and the upper part of the box is situated the vertical
cog wheel. Also this fixed bracket serves to furnish a bearing for the front end of
the spindle of the horizontal cog wheel, the outer end of the said spindle being formed
with a square stud or recess to receive a manipulating handle.
Thus when the bevil gearing is rotated, the rod is raised or lowered, and the
moveable casement opened or closed, and when completely closed, forms a very
secure fastening.

as well as inwards by a variation in the shape and disposition of the arm and bracket
upon the said casement.

Improvements in Mechanism for Opening, Closing, and Securing
Moveable Casements, and other similar Structures.
I HENRY STANHOPE OWENS of Forne Lea Greenhill Road, Moseley in the county
of Worcester Brassfounder 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 the construction and arrangement of parts constituting
mechanism whereby moveable casements, sky-lights, or other similar binged structures
may be adjustably opened or closed, or held securely when closed, and its object is to
provide, that the upper end of the operating rod which is either formed into a slide,
or attached to a slide, shall travel in a slide guide, such guide being also in most cases
of peculiar construction, the said slide communicating motion to the said casement by
means of a hinged arm or link, the outer end of which is secured to a bracket or
fitting upon the casement; that the operating rod shall at its lower end be actuated
by means of bevil gearing carried within a box of special construction, one of the
said wheels serving as a screw nut working upon a screw thread formed on the said
rod. This mechanism may be applied to the operating of casements opening inwards
or outwards.
I will now proceed to more particularly describe and explain how this my invention
is to be performed having reference to the accompanying illustrative sheets of
drawings in which :-.
Fig. 1, is a front elevation of the invention as applied to a moveable casement
opening inwards.
Fig. 2, is a side elevation of Fig. 1.
Fig. 3, is a front elevation of the invention as applied to a moveable casement
opening outwards.
Fig. 4, is a side elevation of Fig. 3.
Fig. 5, is an enlarged detailed view of the slido guide, slide and arm &c. as shown
in Figs. 1, & 2.
Fig. 6, is a side view of Fig. 5.
Fig. 7, is an enlarged sectional plan view at A-B, (Fig. 5).
Fig. 8, is an enlarged detailed view of the slide and arm &c., as shown in
Figs. 3, & 4.
Fig. 9, is a side view of Fig. 8.
Fig. 10, is an enlarged sectional elevation of the bevil gear mechanism.
Fig. 11, is a front view of the box &c., carrying the bevil gear mechanism.
Figs. 12, & 13, are views in detail of the manipulating handle.
Fig. 14, is a view of a modified form of slide and slide guide.
As applied to a casement hinged at the bottom and opening inwards, for instance,
its construction and arrangement would be somewhat thus: see Figs. 1, 2, 5, 6, 7
10, 11, 12, & 13. Upon the casement frame a, and at the side of the upper part of
the casement b, I provide a slide guide or channel c. This guide I construct
preferably thus I make a piece of strong metal either drawn or cast into a part
ubulan

page_text: In the said base part are made the screw down holes ƒ, which are readily accessible
through the open slot d.
Working in this guide c, is a slide 9. to which is attached the upper end of an
operating rod, or, if desired, the upper end of the said rod itself may be shaped to
so form the slide.
Upon this slide a joint is made at i, to receive the one end of a link or arm j. The
other end of this arm or link j, is further jointed to a bracket or other fitting k, upon
the moveable casement b.
Again. At the lower end of the aforesaid operating rod h, which extends down the
side of the window &c., it is screwthreaded, and at such part a gearing box 1, through
which the said screw passes is secured to the casement frame or fixture.
Within this box is provided a bevil wheel nut in, working upon the said screw,
and also at the inner front part of the said box, is a second (horizontal) bevil
wheel n, gearing thereinto. Opposite to the centre of the horizontal bevil wheel n,
is provided a fixed bracket o, between which and the upper part of the box is
situated the vertical cog wheel m. Also this fixed bracket serves to furnish a
hearing for the front end p, of the spindle 7, which carries the horizontal cog
wheel, the outer end of the said spindle being formed with a square stud, or a
recess r, the latter preferred, to receive a manipulating handle s.
Thus when the bevil gearing is rotated the rod is raised or lowered, and the
moveable casement opened or closed, and when completely closed, forms a very secure
fastening as seen in Figs. 4, 7, 8, 9, 10, 11, 12, & 13. The same device may be
readily adapted to moveable casements moving outwards, by a variation in the shape
and disposition of the arm j, and bracket, upon the said casement. In other
respects the details are similar to those already described, and their arrangement and
action will be readily understood from the drawings.
While I prefer the form of slide guide as already explained and therefore have
described and illustrated it, yet I may substitute therefor any other suitable guide
without departing from the nature of this my invention as seen for instance in
Fig. 14.
I am
am aware that a vertical rod and also bevil cog wheels have been used in
mechanism of this kind, and therefore I do not wish to claim these broadly but :—
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
1. In mechanism for opening, closing, and securing moveable casements, skylights,
and other similar structures, the combination with the upper end of the operating
rod, of the slide y, working in the slide guide c, and carrying with it the end of
the link j, or j, substantially as described and illustrated upon the drawings.
2. The construction of the slide guide c, from a piece of semi-tubular section drawn
or cast metal, substantially as described and illustrated.
3. The combination with the gear box 1, of the fixed bracket o, serving as a
resistance collar for the cog wheel m, and also furnishing a bearing to carry the inner
end p, of the spindle q, substantially as set forth.
4. The general combination and arrangement of parts constituting these my
improvements in mechanism for opening, closing, and securing casements, skylights,
and other similar structures, substantially as hereindescribed and illustrated upon the
drawings, and for the purposes specified.
