I HENRY JONES BROADWAY of Miranda Villas, Whateley Road, Handsworth, in
the county of Stafford Clerk do hereby declare the nature of this invention to be as
follows:-
Improvements in what are commonly known as Casement or Fanlight stays and
fasteners, for holding the Casement, Fanlight, or Window, secure when closed and
when open firm; consisting of a plain or unnotched bar or stay upon which a slide
works, the bar or stay being held in position by a grip like cam or excentric boss or
lever which grips the bar or stay and so holds and fixes it in position; the stay or
fastener according to my invention is simple in its construction, efficient in its action
and cheaply made.

Improvements in Casement or Fanlight Stays and Fasteners.
HENRY JONES BROADWAY of Miranda Villas Whateley Road Handsworth in the
County of Stafford, Clerk, 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:-
My invention consists in constructing what are commonly known as Casement or
Fanlight stays and Fasteners for holding the Casement or Fanlight securely fastened
when closed and when onen firm.

page_text: My said invention consists of a Common plain flat Bar or Stay of metal upon which
a slide works, the Bar or Stay being held in position by an eccentric boss or lever
which grips the Bar or Stay and so holds and fixes it in position, the stay or fastener
according to my invention is simple in its construction and efficient in its action.
I will now proceed to describe my invention with reference to the accompanying
Drawings and the manner the same is to be carried into effect.
Figure 1 is a stay or fastener constructed according to my invention for holding
Casements or Fanlights securely fastened when closed & when open firm, the slide
securing the stay being shown fixed in position & to increase the frictional contact of
the bearing face a strip or piece is interposed between the grip like boss and top
of stay.
Figure 2 is a section of the slide so as to better exhibit the action of the Grip
of the eccentric upon the top of the stay, this drawing shows the Grip raised out of
action, when in this position the bar or stay is free to slide up or down.
Figure 3 is a plan of the stay or fastener this drawing exhibits the plate fastened
on base of slide by which it is secured to the sill of the Casement.
The same reference letters-indicate the same parts throughout, A is a plain bar of
metal at one end of which a joint piece B is fixed for attaching the stay to the Case-
ment, at the other end of bar is rivetted a small knob C to prevent the grip slide E
from leaving the bar, D is an eccentric boss or lever which presses against the friction
plate Fwhich grips the face of the bar A. D2 is the lever which actuates the
eccentric Boss, G is a brass movable plate rivetted on the underside of E by which the
slide is fixed to the sill of Casement.
In order to adjust the stay or fastener to any position required for keeping open or
closed the Casement or Fanlight it is only necessary to turn the eccentric D which
works upon its fulcum D 3 into the position represented in Figure 2 so as to remove
the grip of the eccentric from the friction plate F when the bar A can be moved
inward or outward and so open or Close the casement as required, when in this
position the lever D 2 is depressed bringing the eccentric or enlarged part of boss D
forcibly in contact with the friction plate on the stay and so forcibly holding the
parts in position as represented in figure 1, so that in order to adjust the stay
attached to the Casement or Fanlight it is only necessary to raise the lever of the
eccentric grip, when the parts are liberated and the stay free to be moved in or out.
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 :-
-
The improvements in what are commonly known as Casement or Fanlight stays or
fasteners for holding Casements or Fanlights securely fastened when closed & when
open firm, consisting of a plain metal bar upon which a slide works the said slide
being held in position by an eccentric boss or lever the parts being arranged and
acting in the way & for the purpose as described & set forth in Figures 1, 2, 3, of the
accompanying Drawings.
