To all whom it may concern:

Be it known lthat I, IGNACY WuoBLnwsKI, a subject of the Emperor of Austria, and a resident of Krakow, Province of Galicia, Austria-Hungary, have invented certain new and useful improvements in Casement- Windows, of which the following is a specification ac- This invention rclatcs to improvements in French or caseinent windows, more particularly to that class of French windows which open inwardly, and the objects of the invention are to render such inwardly opening windows water tight and practically air tight so that neither water nor dust can pass through the joints.

Other objects of the invention. are to enable one Wing of a double window to be opened by itself while the other remains looked, and to further enable the window to be lockod so that it cannot be opened from the outside.

The invention is equally applicable to doors, which may be locked at night or whenever desired and left free to be swung open and closed at other times.

Further objects of the invention will hereinafter appear and to these ends the invention consists of a French or casement window for carrying out the above objects cinbodying the features of construction, combinations of elements and arrangement of parts having the general mode of operation substantially as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which,

Figure l is a vertical sectional elevation of a window cmbodying the invention on line lvl of Fig. 2, looking in the direction of the arrows; Fig. 2 is a horizontal sectional view, partly broken away, on the line 242 of Fig. 1, looking in the direction of the arrows; Fig. 3 is a detail vertical sectional view, partly broken away, through the .meeting rails of the sashes on the line 3-3 of Fig. 2, looking in the direction of the arrows; Fig. 4 is a detail side view of one of the pivots for the window.

In the class of windows to which this invention belongs the window sash is adapted to be raised from its seat on the window sill and then swung open inwardly. i' The window may be either single or double, and the l construction appliesl equally well' to large or small windows, or to doors, When the sash is in its lowered position it is locked against Swinging movement, and means are provided for raising and lowering the sash or sashes and for locking them so that they cannot be opened from the outside. Means are also provided for' insuring a tight joint between the sash and the window casement at all points, and a tight joint is insured between the meeting sash rails in. the case of a double window. Provision is also afforded for draining off the condensed moisture which accumulates on the inside of the window panes.

Referring to the drawings, A represents the bottom rail of the frame or window sill, Brrepresents the top rail of the frame, and G one of the side rails of the frame. At the top of the casement or embrasure is provided an outer top rail D arranged outside of the frame B and adapted to coperate with the window sash or sashes.

The lower sash rail E and the upper sash rail F ar'e adapted to interlock respectively with the window sill A and the outer top rail D, while the side sash rails Gr are adapted to interlock with the upright side rails 0 of the frame, thereby forming a tight joint around the window casement. Interlocking connections are also provided between the meeting sash rails H and I to form a tight joint.

rlfhe window sill A and lower sash rail 'E in this instance are provided with interlocking grooves and ribs or projections extending across the width of the window, and preferably the window sill A is provided with a groove J, while the lower sash rail E is provided with a rib K adapted to enter the groove J and form a tight joint. In this instance the sill A is provided with a metallic strip L extending across the window in which the groove J is formed, while the sash E is provided with a coperating metallic strip O having the rib K, and these metallic strips may be of zinc or any other suitable metal, but the invention is not to be understood as limited to metallic strips extending along the sill and sash, for the coperating groove and rib may be formed in any other suitable manner or of anyA other suitable material. PreferablyV the window sash E extends downwardly in front of the upper portion of the sill A or strip L as at P to insure a tight joint to prevent the entrance of water, air and dust from the outside.

The upper sash rail F and the outer rail D are also provided with interlocking tongues and grooves in any suitable manner, in this instance the sash being provided with a downwardly extending tongue or rib Q, which interlocks with an upwardly extending tongue or rib R on the rail D, each tongue or rib extending across the width of the window. As shown in the drawings, these interlocking connections are formed by metallic strips S and T, but the invention is not limited to said strips. These strips engage each other hook fashion and each-is substantially in the form of a hook. The hook formed by the strip S, as shown, extends upwardly, while the hook formed by the strip Q extends downwardly, so that an interlocking connection is formed when the sash E is lowered into the groove J. Preferably, the hooks or tongues Q and B are provided with inclined meeting faces which engage each other when the window is in lowered position. In order to enable the window to be raised sufficiently to free the interlocking connections at top and bottom and permit the window to be opened, sufiicient space is providedjfbetween?:thef'npper portions frame B to permit the desired vertical movement.

As shown, the upper sash rail F is provided with the upwardly extending projection W which slides along the inner face of the outer rail D and overlaps the same to insure a tight joint. A convenient construction for the upper sash rail F and rail D is shown in Fig. 1, in

which the sash is recessed at X and the rail D is recessed at Y to afford a clearance space Z between said recesses.

In order to drain off condensed moisture which collects on the inside of the window panes a groove a is provided in the sill A or strip L extending the width of the frame inside of the sash, and connecting channels or outlets b and c extending downwardly and outwardly connect the groove a with the outside of the frame, whereby the water collecting in the groove a may drain off. Preferably the channels b and c are out of line with each other to prevent the entrance of air. The passages b, as shown, communicate with the bottom of the groove J as do the passages c, so that any water which may enter from the outside and collect in the groove J will drain off.. In this instance a metallic angle plate cl is provided to catch the drip from the channel c. As shown, this angle plate cl extends partially under the strip L, then downwardly along the outer upright surface of the window sill and outwardly over the masonry of the casement, forming a drip plate. The inner edge of the angle plate d may be locked between the strip L and the sill A, and for this purpose the strip L is grooved at e to receivethe enlarged or curled end of the angle plate d.

The side frame C and side sash rails G are provided with coperating grooves and tongues or ribs, in this instance the side frame C having grooved metallic strips f, into which extends the tongues g on the metallic strips h on the sashes, and these strips extend throughout the height of the sashes and frames. Preferably also the side sashes G overlap the outside faces of the side frame C as at i to insure a tight joint.

The window sashes are pivoted to swing open and shut in any suitable manner, in this instance the side frames being provided with upwardly extending hooks j over which are placed the eyes 70 connected to the window sashes. Preferably the shanks of the pivotal hooks j eXtend outwardly from the side frames at an angle so that as the sash is lowered into locking position, it is drawn against the side frame, thereby drawing the rib g into its coperating groove in the side frame to make a tight joint.

In order to raise and lower the window sash or sashes a lever Z is 'suitably pivoted to one of the side frames. In this instance the lever being pivoted at oI on a plate p secured to the side frame O in any suitable manner as by means of the screws q. The lever Z is preferably provided with a long arm 1* and a short arm s which may be in the form of. a hook. The short arm s is adapted to coperate with a projection t on the window sash. When the lever Z is moved into the dotted position shown in Fig. l theshorter arm s is moved upwardly under the Projection t on the sash, thereby raising the sash to permit the window to be swung on its pivots. The lever l may be moved slightly longitudinally on its pivot pin 0 to permit the longer arm of the lever to be moved under a stop or proj ection u on the side frame O and therebymaintain the sash in raised position. When the'sash or sashes have been lowered into looking position as shown in Fig. 1 the lever l may be moved into the upright position shown in solid lines, and in order to prevent the sashes from being opened from the outside the lever is provided with a hook r on its upper end adapted to engage a recess w in the sash and thereby prevent the sash from being raised from the outside.

In order to insure a tight joint between the meeting sash rails H and I an outside overlapping vertical strip x is provided on one of the sashes, and furthermore the meeting faces of the rails H and I are provided with interlocking hooks y and z, which are adapted to engage each other when the sash or sashes are lowered into locking position and are disengaged when one sash is raised. A handle a' may be provided on the inside of one of the meeting sash rails preferably opposite the interlocking hooks y and z.

In accordance with this invention one wing of a double window may be raised and opened, while the other wing is left in closed position, which is extremely desirable for suitable ventilation under different circumstances. Both sashes may also be raised to permit ventilation under the lower sashes without Swinging either sash open. It is understood that in case of double windows or doors each sash or door is provided with a raising and lowering device as illustrated in the drawings. Furthermore double windows or winter windows may be constructed in which both the outer and inner sashes operate upon the principles of this invention. As shown in Fig. 1, the inner sides of the top and bottom rails A and B of the frame are constructed to afford provision for inner sashes. As shown, the window sill A is provided with a groove 2, while the top rail B is provided with a hooked projection 3. The said groove 2 and projection 3 extend across the width of the frame and are adapted to receive the inner sashes of the double window. The embrasure may be otherwise suitably constructed to receive a double window. The material of the window frames and sashes may be of any suitable construction, as for instance, wood or metal, or any other desired material. The window or door construction embodying this invention is also applicable for windows and doors comprising one, two or more parts, and such doors or windows may be applied in any suitable manner either for house construction or for balconies.
