7 Claims.

This invention relates to doors and particularly pertains to a door of the type embodying an opening in the upper portion thereof and equipped with a vertically slidable window-sash adapted to be positioned to close said opening and also to be lowered to uncover the openingr either wholly or in part.

In doors of the above character it has heretofore been the practice to provide the door with an enclosed recess into which the window sash is adapted to be lowered. This arrangement has proven unsatisfactory in that the sash-receiving recess is liable to entrap water, snow, dirt and other substances, such as to interfere with the proper lowering of the sash into the recess, and which substances ordinarily cannot readily be removed without the provision of removable covers or panels whereby access to the interior of the recess may be had.

A primary object of the invention is the provision of a construction in a door of the type above referred to whereby the use of covered or enclosed sash-receiving recesses may be obviated.

Another object is to provide a door equipped with a vertically slidable window-sash in which the sash is adapted to be positioned to afford a closure for a window opening in the upper portion of the door and when so positioned to be effectively locked against opening from the exterior of the door, and in which the sash-track is Vso arranged that the sash may be lowered to overlie a lower panelled portion of the door.

Another object is to provide a means whereby the sash may be securely held in one or more partly opened positions so as to afford ventilation space in the upper portion of the door without fully uncovering the window opening.

Another object is to provide an arrangement whereby the sash will be securely held in either of its various positions on the door against rattling and against accidental displacement.

Another object is to provide a construction whereby the window-sash may be readily removed from the door.

Another object is tol provide a construction whereby the sash-track may be formed integrally in the door stiles so as to obviate the use of separate guide strips, and yet permit ready removal and replacement of the sash.

A further object is to provide a construction whereby doors of usual thickness may be equipped with vertically slidable sash and with the sash disposed within the thickness of the door thereby avoiding undesired projections on the face of the door.

With the foregoing objects in view, together y with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawing, in which:

Referring to the drawing more specifically A indicates 'generally a door which embodies the usual stiles I 0 and I I, top and bottom rails I2 and I3, and an intermediate rail I4. The upper portion of the door is formed with an opening B framed by the stiles III and II and the rails I2 and I4; and the lower portion of the door is closed by suitable panelling here shown as comprising a single panel I5. The opening B may be covered by a screen I6 carried by a frame I'I, which latter is mounted on the outer side of the door and is preferably detachably connected thereto by screws or other suitable fastenings in the well known manner.

The faces of the stiles and rails are preferably flush and extend on a common plane on the exterior side of the door, and the inner faces of the stiles and the upper and lower rails are flush, but in carrying out the invention the inner face of the intermediate rail I4 is spaced inwardly from the inner faces of the stiles as particularly shown in Fig. 2, and the upper inner edge of the rail I4 is formed with an upstanding flange or tongue I9.

The stiles I0 and II are formed on their inner edges with longitudinal channels 20 and 2l which extend between the upper and lower rails I2 and I3 past the intermediate rail I4 in'spaced relation thereto, and which channels constitute tracks or guideways in which a window sash C is mounted to slide vertically throughout the length of the space extending between the rails I2 and I3. The channels are thus adapted to be formed on the stiles by means of a sticker machine and accordingly obviate the use of separate moldings or other guide members applied to the stiles. The door` stiles thus formed constitute jambs for the vertically slidable sash.

The sash C is formed of a width slightly less than the distance between the stiles II] and II and as a means for affording slidable connection between the sash and the channels, spacedV aligned projections 22-23 are provided on the Side edges of the vertical side rails of the sash and arranged to project into the channels in slidable engagement therewith. The projections are here shown as comprising screw-eyes, the threaded Shanks of which are screwed into the sash and the heads or, eyelet portions of which are arranged to project into the channels with the opposed broad sides thereof extending in the direction of the length of the channels. However, the projections may comprise staples or any other suitable attachments.

The projections 22 are located near but spaced from the upper 'edge of the sash, while the projections 23'are located near butspaced from the lower edge of the sash, with the projections on one edge of the sash disposed opposite those on the other. stitute spaced guide members on opposite edges of the sash adapted to slide in the guide-way channels on the stiles.

As a means for enabling positioning of the projections 22 and 23 within the channels 20 and 2l in mounting the sash on the door and to permit its removal therefrom in eifecting detachment of the sash from the door, the outer walls of the channels 20 and 2I are formed with notches 24 and 25 which open through the inner faces of the s tiles, are opposed to each other, and are located preferably about the mid-length of the channels. In mounting the sash on the door either the upper pair of I projections. 22 or the lower projections 23 are passed through the notches 24 and 25 to position the projections within the channels, whereupon the sash is either raised or lowered to a position to bring the other pair of projections opposite the notches 24 and 25 through which the latter projections are then passed, thus bringing both pairsof the projections into engagement with the channels. By a reverse operation the sash may be removed from the door.

The sash is formed of a thickness preferably less than the distance between the inner face of the intermediate rail I4 and the inner faces of the stiles I0 and II, and the projections are arranged at such distance from the outer face of `the sash that when engaged in the channels the sash may be raised and lowered in the channels in front of the rail I4. While the inner face of the sash may project beyond the inner faces of the stiles I0 and II the sash is preferably formed so that its inner face will be substantially flush with or slightly spaced inwardly from the plane of the inner faces of the stiles, as indicated in broken lines in Fig. 2 so that in shipping or packing the doors may be stacked flat one on top of the other. To further facilitate packing of the doors the space in front of the panel I5 and rail I 4 on the inside of the door and below the sash is of such dimension that The projections 22 and 23 conthe screen frame I1 unattached may be positioned therein.

Leading inwardly from the inner walls of the channels 20 and 2| into the side walls of the opening D are recesses 26 and 21 which are spaced apart such distance as to receive the projections 22 and 23, as indicated in dotted lines in Fig. 2; the recesses being so disposed that when the sash is in its uppermost or near uppermost position the uppermost projections 22 may be advanced laterally into the recesses 2S by shoving the upper portion of the sash toward the outer side of the door, and then on lifting the sash to position the upper margin thereof within a channel 28 formed on the under edge of the top rail I2 to receive it and such distance that the lower edge of the sash will clear the upper edge of the tongue I9, the lower projections 23 may be advanced laterally into the recesses 21 by shoving the lower portion of the sash to a position over the tongue I9 on the rail I4. The recesses 26 and 21 are of such vertical length as to permit slight upward and downward movement of the sash while the projections are positioned therein, and to allow lowering of the sash after it has been disposed above the rail I4.

The lower edge of the sash is formed with a channel 29 arranged to receive the tongue I9 when the sash is lowered into its closed position on the rail I4.

The sash is of such length that when in its closed position with the tongue I8 projecting into the channel 29, its upper edge will project a short distance into the channel 28 so that the sash will then be held against inward displacement without first lifting the sash to free the tongue I9 from the channel 29.

In order to obviate the projections from becoming seated on the bottom walls of the recesses 26 and thereby lobstruct lowering of the sash to an open position, said bottom walls are downwardly inclined toward the channels, as indicated at 26' in Fig. 2, so that the projections on being moved downwardly onto the inclines will be directed forwardly into the channels.

Means are provided for locking the sash in its closed position against opening from the exterior side of the door. This means comprises a clamp fastener D mounted on the upper rail I2 and adapted to be positioned to effect a wedge action between the top rail I2 and the upper edge of the sash. The fastener comprises a bearing member 30 arranged in the channel 28 and pivotally supported on the shank of a screw 3| which is passed through the outer wall of the channel 28, through a bore in the member 30, and screwed into engagement with the other wall of the channel, as particularly shown in Fig. 5. The member 3U embodies an elliptical portion 32 extending eccentrically of the pivotal mounting of the member 3l! which portion is adapted, on swinging the member 30, to be positioned either to exert a downward pressure on the sash to clamp the latter against the rail I4 or to free the sash to permit upward movement thereof into the channel 28. The member 30 is formed with a handle 33 which projects downwardly below the lower margin of the top rail I2.

A screw 34 is screwed into the upper edge of the sash at a point where the head of the screw will serve as a bearing plate for the fastener; the screw aording a means of adjustment between the sash and the fastener so that proper spacing of the bearing point between the head of' the screw and the fastener may be effected by screw ing the screw inwardly or outwardly.

The overlap at the upper margin of the sash by the rail I2 afforded by the channel 28, and the overlap at the lower margin of the sash afforded by the tongue I9 and channel 29 serves as an effective weather seal at the upper and lower ends of the sash, and as a means for providing a weather seal at the sides of the sash, the door stiles I and I I are formed along their inner edges at the outer margin of the opening B with tongues 35 and 36 which overlap the outer faces of the side rails of the sash, as shown in Fig. 4.

Means are provided for limiting downward movement of the sash in a plurality of partly open positions which means embodies a dependent elongated pawl 31 arranged in a recess 38 formed in one of the side edges of the sash. The upper end of the pawl 37 is xed on a rock shaft 39 loosely journalled in the sash and tted with a knurled head 40 adapted to be manipulated to swing the pawl outwardly toward the bottom of the channel 2|. The pawl is normally positioned entirely within the recess under the action of gravity. Formed `:in the bottom wall of the channel 2| is a series of arcuate recesses 4I spaced suitable distances apart, which recesses are designed to receive the lower end of the pawl 3'I when the latter is swung outwardly thereinto, as shown in Fig. 7. The recesses 4I are located at such points that when the sash is disposed in a position to permit engagement of the pawl in a recess the sash will occupy a partly opened position, that is, with its upper edge spaced downwardly from the top rail I2.

While the lower rail I3 serves as a stop to limit downward movement of the sash, a pawl receiving recess 42 is provided in the channel 2l at a point where it may be engaged by the pawl 3l when the sash is disposed nearly at its lowermost position, that is, with the opening B fully uncovered so that the sash may be clamped under the action of the pawl 31 and held against rattling, as will presently be described.

In the operation of the invention, the sash is assembled on the door, as before explained, with the projections 22 and 23 disposed in the channels and 2|, and when it is desired to close theopening B the sash is lifted to such position that the upper projections will ride into the recesses 26 and the upper end of the sash will enter the channel 28 and the lower projections 23 will enter the recesses 21 by shifting the sash inwardly relative to the guide channels 20 and 2|, whereupon the sash is lowered onto the rail I4 where the tongue I9 enters the channel 29 on the sash, as shown in Fig. 2. In the meantime, the fastener 30 has been disposed clear of the upper end of the sash, as indicated in broken lines in Fig. 6. When it is desired to lock the sash in its closed position, the fastener is swung to the position shown in full lines in Fig. 6, so that the elliptical portion will bear against the head of the screw 34 and thereby tightly clamp the sash downwardly against the rail I4.

When it is desired to open the sash, the fastener 3|) is released and the sash lifted upwardly to disengage it from the tongue I9 whereupon the lower edge of the sash is moved outwardly to bring the lower projections 23 into the channels 20 and 2 I. 'Ihe sash is then lowered, which movement initially causes the upper projections 22 to ride down the inclines 26 into the channels, whereupon the sash is positioned to move downwardly in the guide channels past the rail I4.

When it is desired to hold the sash in-a partly openposition, the pawl 31 is swung outwardly by turning the knob and caused to enter one of the recesses 4I, and when it is desired to. fully open the window the sashis lowered until-it either abuts against the bottom'rail I3 or kthe pawl is engaged with the lower recess 42.v

When the pawl is engaged in one of the recesses 4I or 42, as shown in Fig. '7, it extends at an angle to the vertical, and accordingly the weight of the sash in exerting a downward pull on the upper end of the pawl, tending to advance it downwardly with the engaged lower end of the pawl opposing such movement a lateral thrust will be imposed on the sash causing the latter to'beA advanced toward and clamped against the stile III. The pawl 31 will then serve not only to hold the sash against downward movement but to clamp the sash against vibration as well. l Disengagement of the pawl 31 is effected by merely lifting the sash, as upward movement of the sash will free the pawl,'whereupon it will gravitate back into its recess 38 clear of the stile There are occasions when it is desirable to remove the sash from the door, in which vevent it is manipulated to pass the projections 22 and 2 3 through the notches 24 and 25, as by iirst pass'-- ing the projections 23 through the notches, lo'wering the sash, then passing the projections 2.2v

through the notches.

From the foregoing it will be seen that I have provided a door fitted with a vertically slidable sash, which is simple and economical in construction, which embodies few parts adapted to be readily assembled, and in which the parts are so arranged as to be readily accessible.
