PROVISIONAL SPECIFICATION.
Improved Means for Adjusting Window Casements, Swing Glasses,
Ventilators, and the like in Any Desired Position.
I DAVID OSBORN of Berkhamsted in the County of Hertfordshire Builder, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable casements, swing glasses, ventilators,
and the like to be securely held at any desired angle in an automatic manner,
without the necessity of manipulating any portion of the stay at each movement of
the casement, or the like.
According to this invention I construct frictional pivots in such a manner as by
the operation of a screw or nut, the pivotted parts shall compress a bar or bars in
such a manner as shall hold the bar or bars sufficiently tight at an angle and so
secure the casement, swing glass, or the like in any desired position.
The improved device consists essentially of frictional pivoted parts engaging one
or more bars or rods, which said bars or rods connect in a suitable manner the
casement swing glass, or the like to the frame or portion in which the casement or
other article works.
One way of carrying out this invention is to construct a folding bar with a
frictional pivot at each end, one of which is attached to the casement, swing glass
or the like, and the other is attached to the frame or portion in which the casement
or other article works.
Where only slight restraining power is required the following bar may be
constructed with one frictional pivot, and one free pivot.
As a modification of this invention instead of a folding bar I substitute a single
bar having a frictional pivot at each end, one of which is made to slide along a
slotted plate or slide rod attached to the casement, swing glass, or the like, the
other frictional pivot being fixed to the frame, or portion in which the casement or
other article works; or vice versa as may be most convenient. Or the bar may be
made to slide along a slotted plate, or a slide rod without a frictional pivot at that
end. Or the bar with its frictional pivoted at one end, may itself be slotted with a
pin engaged therein attached to the casement, swing glass, or the like or the
attachment may be vice versa. Or the bar with its frictional pivot at one end may
be made to slide in a rotating sleeve, fixed to the casement, swing glass, or the like
or the attachment may be vice versa.

Improved Means for Adjusting Window Casements, Swing Glasses,
Ventilators, and the like in Any Desired Position.
I DAVID OSBORN of Berkhamsted in the County of Hertfordshire, Builder, 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:
The object of this invention is to enable casements, swing glasses ventilators and
the like to be securely held at any desired angle in an automatic manner, without
the necessity of manipulating any portion of the stay at each movement of the
casement or the like

page_text: According to this invention I construct frictional pivots in such a manner as by
the operation of a screw or nut, the pivotted parts shall compress a bar or bars in
such a manner as shall hold the bar or bars sufficiently tight at any angle and so
secure the casement, swing glass or the like in any desired position.
The improved device consists essentially of frictional pivotted parts engaging
one or more bars or rods, which said bars or rods connect in a suitable manner the
casement swing glass, or the like to the frame or portion in which the casement or
other article works.
One way of carrying out this invention is to construct a folding bar with a
frictional pivot at each end, one of which is attached to the frame or portion in
which the casement or other article works and the other end to the sash or other
article to be held thereby.
Where only slight restraining power is required the folding bar may be
constructed with one frictional pivot and one free pivot.
As a modification of this invention instead of a folding bar I substitute a single
bar having a frictional pivot at each end, one of which is made to slide along a
slotted plate or slide rod attached to the casement swing glass or the like the other
frictional pivot being fixed to the frame or portion in which the casement or other
article works; or vice versa as may be most convenient.
Or the bar may be made to slide along a slotted plate, or a slide rod without a
frictional pivot at that end. Or the bar with its frictional pivot at one end, may
itself be slotted with a pin engaged therein attached to the casement swing glass, or
the like or the attachment may be vice versa.
And in order that my said invention may be fully understood I will describe the
same with reference to the accompanying drawings in which,
Fig. 1 shews elevation of my invention fitted as a fanlight stay.
Fig. 2 side elevation of same shewing fanlight partly open.
Figs. 3 and 4 respectively shew similar views illustrating another way of carrying
out my invention as applied to fanlight stays.
Fig. 5 shews section through line A. B. (Fig. 1) and
Fig. 6 shews section through line C. D. (Fig. 3).
Figures 1 to 6 also represent the application of my invention as casement stays
by applying them in a horizontal manner to the bottom or top thereof as may be
most convenient instead of in a perpendicular manner as represented on the
drawings.
Fig. 7 shews elevation of my invention as applied to a swing glass and Fig. 8
side view of same hereafter referred to.
Similar letters denote the same in all views.
At Figs. 1 and 2 a shews portion of a fanlight sash. b part of frame to the
upper part of which it is hinged c rod fixed on frame b on this rod a sleeve d
works and to this latter an arm e is pivotted the other end of said arm is pivotted
at f. (to a bracket fixed to the sash a) by frictional pivot g. shewn in section at
Fig. 5. so that when the screw h is tightened it causes the parts in immediate
contact with arm e to press upon both sides of said arm e and so create sufficient
friction to keep the sash at any desired angle.
With reference to Figs. 3 and 4 the arm e is pivotted in two pieces o. o. sliding
on a guide piecej by the screw h¹ so as to form a frictional pivot this portion is
shewn in section at Fig. 6. the pieces o. o have grooves in them and slide on
the guide piece j fixed on side of the piece m which is fixed to the sash the other
end of arm e. is pivotted at f. also by means of a frictional pivot g.
With reference to Figs. 7 and 8. as applied to a swing glass or the like, g shews
the frictional pivot and h h the screw which in this case passes through the stand or
supports q. of the glass and the other end of the arm e. is pivotted to a stud or
button r. working in slotted piece s. (the front elevation of this piece is shewn at
Fig. 8) fixed to the frame t that carries the glass this frame is also pivotted in the
stand or supports at its centre in the usual way shewn at u. and my device with
frictional pivots may be either at top or bottom of glass.

page_text: It will easily be understood that by the above means the sash or glass will be
retained at any desired angle by the friction put on the pivots as aforesaid.
I would remark in conclusion that I do not wish to limit myself to the precise
details or the arrangement of parts herein described and shewn on the drawings
as the same may be varied without departing from the principle of my said
invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Improved means for adjusting window casements fanlights swing glasses
ventilators and the like in any desired position by frictional pivots substantially as
described and shewn on the accompanying drawing.
2. The improved means for adjusting window casements fanlights swing glasses
ventilators and the like in any desired position substantially as described and shewn
on the drawings.
