CASEMENT WINDOW SWINGING MEANS Filed April 22, 1929 2 heet 2 Patented June 28, 1932 DAVID J. BARKER, or SEATTLE, wAsHiNGtr'o'N GASEMENT WINDOW SWING-INC MEANS Application filed Apr'i1'22,

Casement windows have certain advantages, such as the ability to open the entire area of the window frame, but frequently their disadvantages outweigh their advantages. Thus, a casement window, swinging outwardly, cannot be conveniently screened, or the screen obstructs the access to the window necessary to adjust it to position; if a roll screen is used it is expensive, in the first place, and not altogether tight. If the casement window should swing inside it interferes with curtains, shades, hangings, or drapes, and such windows are seldom swung in this manner.

It is an object of this invention, therefore, to provide a casement Window and a means for screening the same, by means of which the easement window may be swung from a full open to a closed position, and by means of which it can be adjusted with the screen in place, without removing the screen, and retained in any selected position. It is also a further object to accomplish the above results without any disturbance of the shades, curtains, hangings or drapes, and to so mount the screen that it may be readily removed when its presence is not desired.

A further object is the provision of inexpensive, yet thoroughly reliable, tight, and convenient screening means for casement windows.

A further object is the provision of operating means for such a combination, particularly for the casement window, by means of which the latter may be moved from within the room, and with a screen in place between the operator and the casement window which is being moved.

A further object is the provision of a mechanism for controlling and operating the casement window, which is readily adaptable, without change of construction, to windows which swing from either side of the window frame.

Other objects, and particularly such as relate more purely to structural details, may be ascertained from a study of the drawings which are attached hereto, of the following specification, and of the claims which, terminate the same.

1929. 'Serial No. 357,038.

My invention comprises the novel parts, and the'novel combination and arrangement thereof, together with subcombinations, as are shown in the accompanying drawings, described in the specification, and as will be more particularly defined by the claims which terminate the same. I

In the accompanying drawings I have shown my invention arranged in a typical installation, it being understood that changes in the arrangement of the parts, and in the details of construction, may be made, within the scope of the appended claims, and without departure from the principles of my in vention.

Figure 1 is an outside elevation of a casesment window, showing my screen in position in the window frame, and the casement window partly open;

Figure 2 is a section of the same on a hori zontal plane.

Figure 3 is a section through the sill, and parts associated therewith, the screen being shown as thrown out of the'way, and the case ment window being closed,

Figure at is a detail, in plan, with parts shown in section on a horizontal plane, and arranged in the positions of Figure 3, a cover plate being omitted for clearness of illustration. i v

Figure 5 is a View similar to Figure 4 of the swinging end of the window, and its relation to the screen and frame when the screen is in position.

Figure 6 is a detail in plan view, ure 7 is a detail section on the line 7 7 of Figure 2.

In the construction, arrangement, and mounting of the easement window 1, and its frame 2, my invention does not diifer from that of the ordinary or usual casement win.- dow. The casement window is shown as pivoted in the usual way by the hinges 10 to the frame 2 at one side or the other of the frame. o The frame includes the usual sill, composed of the inner member 20, and the outer slop:- ing member 21, the two joined in such a Way as to leave an outwardly facing shoulder 22, against which the window seats when closed. The top and side members of the frame may and Fig- 1*.

have shoulders in the same plane as the shoulder 22, as this is ordinarily the case, but this is not essential so far as the present invention is concerned.

A screen 3 is made of a size to fit within the frame 2, preferably in a plane parallel to and just inwardly of the plane occupied by the window 1 when closed; This permits the window to swing freely without interfering with the screen, and the latter is far enough out to avoid interference with shades and the like, hung from the frame 2. As the window 1 seats against the shoulder 22, the screen would ordinarily be just enough smaller to seat upon the inside sill member 20. This screen may assume various shapes, and be mounted in a number of different ways, so far as concerns the member for operating the window 1, but for convenience I prefer that it be hinged, as is indicated at 30, at the opposite side of the frame 2 from the hinges 10 of the window 1. I prefer, further, that it be made articulated, and it is shown as composed of two sections, the outer one hinged upon the inner one, as is indicated at 31 in Figure 2. The hinges 30 are of somewhat special design, whereby their pivot axis is outwardly of the plane of the screen when closed, thereby throwing the screen, when folded and swung outwardly, into the dotted line position of Figures 1 and 2 (see particularly the latter). There it may be engaged by any suitable holding means, such as the stop 4 and catch 40, the latter being pivoted and carrying a weight 41, wherebyit will be pushed aside as the screen swings open and engages it, and will rise again to catch and hold the screen in position against the stop 4, where it will not rattle in the wind.

Casement windows frequently carry a lever catch 11, engageable with a complemental member in the frame, and serving as a handle to move the window. This can be operated only through the frame,if the window swings outwardly, as is customary, and hence it will not be possible to operate the window by this lever 11, or to engage the same with its complemental member, except as the screen 3 is removed from its operative position, nor is it possible to adjust the window with the screen in place, except by a type of mechanism corresponding to that which I will now describe.

This window swinging mechanism includes a member engageable by the operator, as, for example, the turn button or handle 50, and a member engageable with the window, as the link 51. Intermediate these members is a member which can translate the turning movement ofthe operating handle or button 50 into longitudinal movement of the link 51.. This may take the form of a transversely movable bar 5, to one end of which the link 51 is removably pivoted, as indicated at 52, and the transverse movement of the bar 5 may be accomplished by forming it as a rack bar with teeth facing inwardly, with which are meshed the teeth of a pinion 53. The operating handle 50 may be secured to the pinion 58, or the shaftof the latter, or a second pinion 5 may be employed, in mesh with the pinion 53, and this pinion 54 may be made somewhat smaller than the pinion 53, to give added force to the window swinging means.

The link 51 being pivoted at 55 to the casement window 1, and the rack bar 5 being suitably guided, by means to be hereafter described, transverse movement of the rack bar from the position shown in Figure at will cause the window to be projected outwardly, as the rack bar 5 moves laterally. This movement can be stopped at any selected location by projecting a locking dog6 between the teeth of some member of the pinion and rack system, as, for example, between the teeth of the inion 53. It might as well be projected etween the teeth of the rack bar 5, or of the pinion 54:. Preferably, this dog 6 is pivoted at 60 upon a suitable support, in the form of a plate 7, and is actuated by a link 61, slidable in a curved slot 62 in the platev7, so that movement of the locking handle 63 secured to the link 61will project the dog into position between two adjacent teeth of the pinion, and will move the locking handle or pin 63 into position where the side of the slot 62 is in effect a shoulder, normal to the line from pin .63 to the tip of dog 6, which prevents reverse movement of the dog when acted upon by a force applied to the window, as, for example, the wind tending to swing the window open or shut Only by movement of the pin 63 in the slot 62 canthe dog 6 be withdrawn.

The rack bar 5 and the pinion means in mesh therewith, together with the locking dog 6 and its operating means, may all be conveniently mounted upon the cover plate 7. Preferably, the sill member 20 is recessed, as may be seen at 25 in Figure 4, to receive the various operating members, and the cover plate 7, in which the pinions are j ournaled, may be set flush with the upper surface of this sill member 20, though still above the surface of the inclined sill member 21. The cover plate 7 may be bent, and cooperates with flange plates 74 and 2 7, to form a guide 75 (see Figure 7) for the rack bar 5, whereby the rack bar 5 is carried at the outer edge of the cover plate 7, and a slot 76 is left therebelow for the connection of the link 51 to the rack bar. The flange plate 74 forms an apron extending downwardly nearly to the outer sill member 21, but inward from the edge enough to leave a recess for the re ception of link 51 when the window is closed. To close the recess 25 in the uppersill member, to keep out rain, an upwardly flanged plate 73 may be secured upon the sill member 21,

this contacting with and cooperating with the apron 7a to form a water tight joint, thus protecting the operating parts of the mechanism.

With the screen 3 in place, the window 1 may be moved from any position, substantially closed, to the limit of its outward swing, merely by turning the handle 50. It is not necessary to remove the screen for this operation,'since the link 51, the only member which extends outwardly of the plane of the wind-ow 1, extends underneath the lower edge of the screen 3, when the latter is in place. It lies beneath the edge of this screen, and in the outwardly facing surface of the shoulder 22. As will be understood, the link 51 is engaged beneath the lower face of the rack bar 5, through the slot 76.

Now, if it is desired to remove the screen, it is necessary, only, to swing the window 1 open, and in this form of the screen to break the screen at the hinge 31, holding the two parts together, and swinging them outwardly into the dotted line position of Figure 2. The window 1 may not be ordinarily closed completely with the screen 3- in place, since the handle 31 would strike the screen 3 and prevent this, but, nevertheless, this handle may be omitted, or a recess may be formed in the screen 3, thus permitting complete closing of the window with the screen in place. However, this is not important, as whenever the window is closed the screen has no function, and might as well be out of the way.

It will be noted that the window swinging mechanism may be employed with windows which swing either from the right or from the left side. It may be let into either side of the sill, and if it is desired to swing a window which is hinged at the opposite side to the window shown in Figure 2 or 4, it is necessary only to disconnect the link 51 at its connection at 52 to the rack bar 5, and connect to the other end of the rack bar, as is indicated at 56, or to remove the rack bar 5 from its guide 75, turn it upside down, and to connect the link again at the under side of the rack bar. It now slides from the left, as seen in Figure 4, rather than from the right, to open the window. Thus, it is necessary to manufacture only a single device, which will accomplish all of the purposes to which it may be put.

It will be noted that various types of screens might be employed. It is not essenti al that the screen be articulated, or even that it be a swinging type of screen, for the operating mechanism will swing the window, whatever type of screen be interposed between the operator and the window. As a matter of fact, it is not essential that the screen be employed, as my device will serve as a means for swinging casement windows, irrespective of the screen, and furnishes a convenient means of holding the windowin any selected position. p What I clalm as my mventionis: 1. A window swinging means for screened casement windows adapted for securement in the window sill, the sill being recessed in its upper andouter faces to receive the windowswinging means, an upwardly flanged plate cl'osingthe outside of said recess, a transverse guide above and outwardly of said flange, an aprondepending therefrom and contacting with said flange to seal the outer side of the recess, a cover plate closingthe upper side thereof, a member transversely slidable in said guide, means operable from a point inwardly ofthe screen for sliding said member, and alink connecting said member and the window. l i r 2.
