ends to the metal framework or the window, but v this construction has certain practical disadvantages.
According to the invention in a metal casement window having fixed and moving frame members provided with inner and outer co-operating flanges, the guide. bar for the stay arm comprises a rail provided with a retaining rib and formed in one with or united throughout its length such as by welding or riveting to one of the frame members,.the other frame member supporting the stay arm which carries a clamp adapted for sliding engagement with the retaining ribof the rail.
' ,In a preferred arrangement the metal section of the moving frame of'the window along its lower edge is formed with an inwardly extending horizontal flange'constituting the guide rail and along which flange. the window clamp carried on the swinging arm is slidable.
The guide rail, or the metal strip forming the rail and which is attached by riveting or welding to the window section is preferably formed at its extremity with a rib of bulbous section.
A further feature of the invention consists in the manner of attaching the securing clamp to the stay arm by means of its tightening pin, since by anchoring the pin to the arm, it being understood that the head of the pin engages behindthe arm, when the clamp is tightened the arm will berigidly braced by the clamp to the guide rail.
The invention is illustrated in the accompanying drawings in which Figures 1 and 2 are respectively a part elevation and plan view of a metal casement window having a stay fitting in accordance with the invention;
Figure 3 is a transverse sectional view (on an enlarged scale) and showing the clamping mechanism;
Figure 4 is a transverse sectional elevation of an alternative construction of window section;
Figure 5 is a transverse sectional elevation showing a further embodiment of the invention in which the window is constructed to open inwardly.
Referring to the accompanying drawings there is shown a metal casement window comprising a fixed window frame A and a moving frame or window B which is hinged to open outwardly about a centre C (see Figure 2).
On the window frame A is a bracket D, to
which is pivoted one end of a swinging arm or '7 link E of the stay. The other end of the swinging arm carries a clamp indicated generally at F and which is in sliding engagement with a guide bar I on window B.
The essential feature of this invention consists I in a construction in which the guide bar forms a single unit with the metal section of the window and in the arrangement shown in Figures 1-3 the guide bar consists of a metal strip I attached by riveting to the vertical flange of the window hanging rail 3 terminating in a retaining rib 4 which preferably as shown is of bulbous section. The clamp embraces the rib along which it is slidable.
In the construction of Figure 4 the guide bar instead of being attached throughout its length to the section B forms an integral part of the metal section B of the window and for this purpose the vertical flange indicated at 5 of the window section is provided with an overhanging rail portion 3 having the rib l. As shown it is preferable to fit the rib :2 with a liner 4 of brass or other non-rustable material and where the guide bar is attached such as by riveting to the window section as in Figures 1-3, the entire bar may be. formed of brass or other non-rustable material.
According to a further feature of the invention the window securing lamp F, which is formed in two parts 5 and l, is anchored to the swinging arm E of the stay with the result that when the clamp is tightened in addition to its functioning to fix the window by gripping'the guide bar it will also clamp together the guide bar and swinging arm and thus prevent any playtherebetween. The clamping members 6 and l are each formed with a rib-embracing recess shaped to embrace partially and circumierentially the guide bar rib l, thereby providing a large surface area for frictional'engagement of the clamping members 6 and i with the rib section. The guide bar strip comprises an over- It will be appreciated that by eliminating play,
window is set at a small window opening, since in the. normal construction there is a tendency of its shutting of its own accord, due to play at the pivotal points at each end of the arm, Whereas with the clamp of this invention, play can only occur at the pivot between the swinging arm and the window frame.
For this purpose the two parts 6 and I of the clamp are secured to each other by a screwthreaded stud 8, the head or one end 9 of which is anchored to the stay arm E, its other end projecting above the parts of the clamp to receive a thumb or wing nut Ill. The two parts of the clamp are grooved to correspond with the cross section of the rib 4 of the guide bar and in addition are respectively provided with a locating rib and groove indicated at I I. The thumb nut may be secured on the stud 8 by means of a screwed pin I2.
Referring now to Figure 5 there is shown a further embodiment of the invention as applied to an inwardly opening window, in Whichthe metal strip l of the guide bar rail is secured by welding to the vertical flange of the window section B and is formed with a laterally projecting rib l3 as distinct to the arrangement of Figures 3 and 4, where the rail 3, 3' of the guide bar is inclined to the horizontal thereby providing in combination with the window pane, a condensation channel. In Figures 3 and 4 the rib 4 is on one side of the central plane of the rail but alternatively it may be central (not shown). When, however, the overhanging portion is horizontal or substantially horizontal as in Figure 5, by constructing the rib to project upwardly above the plane of the metal the rib itself may be used to provide this channel.
In Figure 5 provision is made for setting the angle of the throw of the tightening piece of the clamp H) as bounded by its locked and release' positions so that it can be properly accommodated within the limited space allowed by the window glazing. For this purpose the stud 8 is formed with a squared portion or spline portion I4 adapted to engage in a spline-receiving groove I5 in the lower half of the clamp, the head of the stud of course being a loose fit in the swinging stay arm E. If on assembly it is found'that the thumb piece fouls the window pane, it is possible by disengaging the squared portion of the stud from the groove in the clamp and turning the screw through or as may be required and then re-engaging the squared portion with the groove, toadjust the setting of the throw of the thumb nut.
In' order to limit the travel of the clamp along the guide bar a stop formed by means of a screw H3 or by crimping a portion I! of the bar itself may be provided.
The sliding stay construction of this invention possesses several advantageschief among which is its neatness of appearance while when the window is in its closed position the swinging stay arm tucks beneath the flange forming the guide bar. Moreover by constructing one of the operating members of the stay as a part integral with the framework of the window, the number of loose parts is reduced.
Moreover, as compared with the existing practice of attaching the guide bar to the window the further advantage that the range of travel of the clamp is increased since it is permitted to move the entire length of the flange.
While the invention is mainly intended for side hung windows with reference to which it has been particularly described, it will be understood that it is applicable to other forms, i. e., top hung, bottom hung, and pivoted.
Although not illustrated it will be obvious that if desired the guide bar or portion of the stay may be integral with the fixed frame or section of the window, although such an arrangement is not so practical as one of the advantages of attaching the guide bar to the moving frame is that it can be utilized as a condensation channel.

1. In a casement window of the class wherein a frame part is movably supported with respect to a fixed frame part, and in which the moving frame part is provided with a-guide rail and the fixed frame part has attached thereto a stay arm, the combination with said guiderail and :said stay arm of a clamp including a two-part sliding member adapted frictionally to engage said guide rail, and a clamping pin extending through the stay arm and the two parts of the sliding member and being positioned to exert clamping pressure on I both the two-part sliding member and the stay arm whereby the c1amp,'the guide rail, and the stay arm will be rigidly looked together.
2. Combination as defined in claim 1 and in which the guide rail is united throughout its length to the movable frame part. f
