` Application May 15, 1950, Serial No. 162,052

` (ci. iss- 76) 6 Claims.

My invention relates to the field of combined doors and windows, and is a continuation-impart of my co-pending application, Serial No. `107,172 filed July 28, 1949.

Although the combined door and window disclosed in my coi-pending application has been found to operate satisfactorily, it has the disadvantage that a portion of each mullion used in the device is difcult topaint and service after the glazing of the window has been completed.

The primary purpose of my present invention is to provide a combined door and window having a mullioned construction that will eliminate the above mentioned disadvantage.

A major object of my invention is to supply a mullion for a combined door and window that can readily be painted or serviced after the Window has been glazed.

Another object of my invention is to furnish a mullion having an extremely simple structure,

that can be fabricated from standard commercially available materials, and can be incorporated in my combined door and window at a relatively small increase in cost.

These and other objects and advantages of my invention will become apparent from the following description of a preferred form thereof, and from the drawing illustrating that form in which:

Figure 1 is a perspective view of my combined door and window;

Figure 2 is ay horizontal cross sectional view of one of the mullions taken on the line 2-2 of Figure l; and

A Figure 3 is a fragmentary exploded perspective View of the mullion and the end portion of one of the sliding panels. i

Referring now to Figure 1 for the general arrangement of my combined door and window, it will be seen that it includes a substantially rectangular framework F having a longitudinally extending head member H, a sill S situ-ated thereunder, and the sill and head member being connected at each end by a vertical side jamb J. Two stationary vertical mullions M that extend from the sill S to the head member H are longitudinally spaced and `situated between the side jambs J.

Two substantially rectangular stationary panes G of glass or other transparent material are supported in the frame F, with each pane being situated in one of the end portions of the frame between one of the jambs J and mullions M. Two longitudinally movable panels P are mounted in the frame F, and due to being glazed, serve the dual function of providing a door to close the space between the mullions M, and serving as windows when so positioned.

`The structureof my present invention is identical in a number` of v.respects to the combined door and window shown in my co-pending application Serial No. 107,172.

The mullions M are similar in cross section but oppositely disposed. Each of the mullions M in.

of L-cross section is provided for each of the mul-` lions M, with the member having the end portion of one of its legs 4| situated adjacent to the leg portion 4t'. The member 4| has a second leg 4|" that extends outwardly therefrom. and is positioned parallel to the ange 39.

Each of the slidable panels P, as may best be seen in Figure 2, has a member 42 that forms the outer vertical end thereof. The member 42 includes a substantially vertical strip 43 having a leg 44 disposed normal thereto on the inner edge thereof. A lip 45 extends inwardly from each of the legs 44, and an inwardly extending hooked member 46 is formed on the outer edge of the member 43. The hooked member 46 includes a short inwardly extending leg 41 that is adapted to be situated adjacent to the leg 4|" when the panel P, of which the hooked member is a part, is in the closed position.

Each of the members 4| and the offset leg portion 40 when it is positioned adjacent thereto are formed with longitudinally spaced tapped bores |48 that are in vertical alignment, with the bores being engaged by screws |49 to removably hold each of the members 4| and leg portions 40 together as an integral unit, as may best be seen in Figures 2 and 3.

It will be noted that with one of the panels Pv being placed in the closed position as shown in Figure 1 that the leg 4|" is engaged by the hooked member 46, with the result that a verr tically extending space |50 of rectangular cross.

section is formed between the forward face of the leg 4| and the rearward face of the leg 41. To prevent the possibility of wind or air passing from the outside to the inside of the building in which my invention is installed, a length of Weather stripping W may be aiiixed to the forward face of the leg 4I. The Weather stripping W is of such a thickness that it fully occupies the space |50 when the panel P is in the closed position as shown in Figures 1 and 2.

The operation and installation of my-combination door and window is extremely simple; The frame F and the various component parts making up the finished combination door and window are fabricated by the manufacturer and dispatched to the building in which it will beinstalled. Each of the frames F is installed in the building in accordance with conventional building practice, and the glazing operation oompleted in the frames prior to the building being put in use. The stationary panes of glass G are situated between the jambs J and the mullicns M, with each pane of glass having the bottom edge thereof resting on the upper surface of the sill S, and the upper edge oi glass in contact in a portion of the head member H. The vertical edges of each pane oi glass G are supported by one of the mullions M and one of the jambs J.

Each of the panels P is longitudinally movable within the frame F due to being mounted on rollers as described in detail in my co-pending applicati-on, Serial No. 107,172. Although the painting of my combination door and window can be carried out prior to the glazing operation being performed thereon, it frequently hap- -f pens that the painting is not done until after this operation has been completed. es a result, certain portions of the window as desc ibed in my co-pending application, Serial No. 107,372 are difficult to paint, and this difficulty is eliminated f by my present window construction. In the window disclosed in my fcc-pending application Serial No. 107,172 it was impossible to paint the interior of one of the mullions M after the window had been glazed, but in my present window the mernber 4l may be removed from the supporting mullion M by loosening the screws Mld. Thus, the interior of the mullion is accessible for painting, as well as the interior ci the member di In addition, by removing the member 1li the weather stripping W can be afxed to the forward face of the leg lll" with a minimum of effort when it is found desirable to include weather stripping as a part of the window. 1t will be apparent that after the weather' stripping W has become damaged or worn by use, that the member di may be removed to permit the replacing of weather stripping 'W with new material.

Although the described structure of the mullion M is fully capable of achieving the results and providing the advantages hereinbefore mentioned, it is to be understood that it is merely illustrative or the presently preferred form ol my invention, and that do not mean to be limited to the details of construction herein shown and described other than as defined in the appended claims.
