To all whom it may concern:

Be known that we, EDwARD FRANCIS, VVILLoUeHBY and EDWARD Manna .BAnroR ItEvILL, subjects of the Kingof 'Grreat' Britain, residing at Wellington, in theLDomim ion of New Zealand, have invented a new and useful Improved Stay for Casement and like Windowsyand we do hereby declare the following to be a full, clear, and exact description of the same. i r

This invention has been designed in order to provide an improved construction of stay for casement and other like forms of windows in which the sashes are hinged within their frames, generally to swing horizontally. The special construction of'stay designed provides forthe casement sash opening and closing freely and for it being retained at any point within the limits of its movement. Its construction is such also as "to provide for the stay bar adjusting itself readily to the variations in the angles necessary to compensate for the different extents to which the sash is opened. the construction provides a lock for locking the sash when it is in the closed position;

The stay is composed generally of two main members, a runner bar that is fastened to the window frame in a line'parallel with the plane thereof, and a stay bar that is pivoted at one of its ends by auniversal joint to the sash and at the other is pivoted to a sleeve mounted to slide along the runnerbar' and adapted to be locked thereto at any point. r v

The invention is illustrated in the accom panying drawings, in which Figure 1 is a side elevation, and

Figure 2 is a front elevation of the stay in position on a window.

Figure .3 is a sectional plan on the line 3-3 of Figure 1.

Figure 4 is a detail view of the means forasapplied to one opeiiin g 'in a means of the'brackets C-'at eachenifsotha In addition '1 he construc- T erect.

P G-1. 1C is the'runner bar.- This islattache'd to; the. inside face of the framefmeinbe'rffi, by

the bar is carried at"a'distanoe"froin tlie" face of A and extends in a line parallel with the member of the sash B to which the stay is to be connected. said'runner bar is a sleeve D that is madeto slide freely along the bar and is provided with thumb screw D passing through it and engaging the bar, by means of which it may be'locked from'movement at any point along the bar. I

E is thestay bar; This has one of its ends .pivotally' attached to the sleeve vD, as at F and its other end attached to the sashB at, a point such that when the sleeve is at the bottom of the runner bar and the sash is in the closed position, the stay bar will extend approximately parallel with the runner bar,

as shown in the drawings... The manner of attaching the stay bar to the sash is such as to permit of it assuming any angle relative Mounted on the thereto both in fa vertical and horizontal plane. This is effected by attaching a hearing bracket G to the faceof the sash B journalling a pinH vertically therein so that its ends project below and above the bracket. The lower end-of this pin'is forked (as at V it Figure 4;) and the top end of the stay bar is ivotally secured to such forki onsequently the opening of the sash will cause the stay bar to turn out on its pivots F and h the sleeve D sliding up the runner bar B as the angle of the stay bar varies in the vertical plane, and the sleeve rotating on the runner bar and the bearingpin 'H rotating in its: bracket G to accommodate for v the varying angles to the horizontal assumed by the stay bar, as the sash opens. Then,by

screwing up the thumb screw D, thesleeve may be locked on the runner bar and thus, hold the sash in the open position. This arrangement and construction of theparts provide for the sash opening and closing freely, as the stay bar readily adjusts itself tov the varying angles and the sleeve runs freely. on the runner bar to permit of such variations.

. Combined with the stay are means for locking the sash in the closed position. These oted onthe upper end of the pin H so as to 'means consist in a catch lever J that is pivturn horizontally, and has its outer end so shaped asto be adapted to engage and fit round the runner :bar B. This catch lever is made of such a length that when the sash is closed, the catch end maybe turned across and sprung over the bar B and will be retaine Y thereby the outward strain on the sash. The catch is made vvith a thumb piece j for grasping and turning it, as shown more same to a window frame, a' sleeve slidable on said runner bar, abracket for attachment to the sash a stay bar pivotally connected at one end to the sleeve, a pin mounted for turning movement in said bracket, and a piv-' otal connection between said stay bar and said pin, and. a catchto engage the runner bar, said catch being also pivotally mounted on said pin.
