DUPLEX DOOR V J .ZeHaz/en Patented Dee. 31, 1929 UNITED s'iA'rEs JAMES RODGER DE HAVEN, F CHAMPAIGN, ILLINOIS DUPLEX DOOR Application led. May 5, 1928. Serial No. 275,497.

The invention relates to improvements in doors of the general type embodying a plurality of closures, any one of which may be upwardly slid from a pocket, to extend across an opening in the upper portion of the door,

one of the closures eing usually a screen, while the other is either a sash carrying a pane of glass, or a panel of wood or metal.

It is the object of the invention to provide a new and improved door of the general type set forth which, while being rather simple and inexpensive, will be efficient and Idesirable and may be constructed for advantageous use as an'outside door, or as a door for inside use in dwellings, apartment houses, oflice buildings, etc.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. l is a front elevation partly broken away showing one of the closures within the pocket and the other extended therefrom.

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1.

Fig. 3 is a view similar to Fig. 1, but showing said one closure extended from the pocket into operative position.

' Fig. 4 is a vertical sectional view on line 4-4 of Fig. 3. /l

Fig. 5 is a detail horizontal section on line 5-5 of Fig. 1.

Fig. 6 is a view similar to Fig. 5 but showing a wooden panel substituted for the glasscarrying sash shown in the other views.

ln the drawings above briefly described, the numeral 7 denotes ,a rectangular frame whose vertical side bars, upper end bar and lower end bar are identified by the numbers 8, 9 and 10 for future reference. e

Secured against the inner 'side of each bar 8 and extending throughout the length of the latter are three parallel ribs 11 preferably formed from a single sheet metal stamping as shown in Fig. 5, said ribs providing two uideways or runways 12 at each side of the rame. Two panels 13--14 extend between the lower portions of the side bars 8 and are in engagement with the lower end bar 10,

providing 4a pocket 15 within the lower-portion of the frame, while the upper portion of the latter is open. Secured to the lower side of the top bar 9, are two parallel ribs 16 which extend between the runways 12.

Two closures 17--18 have their vertical edges slidably received in the runways l2 so that they may be slid into and out of the pocket as occasion, may demand, and the upper edges of these closures are formed with grooves 19 which snugly receive the ribs 16 upon raising of said closures, as seen most clearly in Figs. 2 and 4. Thus, a tight connection between closure and frame is estaby lished when either closure is raised. To hold the closures in adjusted position, springpressed brake shoes 20 are carried by one edge of each closure to Contact slidably and frictionally with the inner side walls of the runways 12. `Preferably, these shoes are formed by the ends of spring metal strips 21, centrally secured as at 22 to the closures. These shoes hold the closures in desired positions, and appropriate finger grips 23 may be provided upon said closures to assist in raising and lowering them. The upper end of closure 17 is preferably provided with a cowl flange 24 which extends outwardly and downwardly over the upper end of the panel 14y when this closure is lowered, as seen in Fig. 4, materially assisting in preventing entrance of foreign matter into the pocket 15.

in the present showing, closure 17 consists of a glass pane and an appropriate carrying frame therefor, preferably formed from sheet metal, and closure 18 is formed bya sheet of screen wire and an appropriate carrying frame therefor. Obviously, this screen wire may be of any desired degree of iineness, even to the point of preventing vision therethrough while still permitting some passage of air. To limit the lowering of this screen, a ller 25 has been shown secured in the lower end portion of the frame.

If desired, a wooden panel such as 17a of Fig. 6 may be substituted for the closure 17, or a metal closure could be used if desired, in which connection, attention is also invited to the fact that numerous parts of the door may A the outer side of said panel las shown in F1g. 4.

Strip 26 is provided with a flexible edge portion 28 formed of felt, rubber or the like, to abut the closure 17, when the latter is raised and said strip is swung to the position of Fig.

2,'and novel provision is made for holding the strip in this position so that any water running down the exterior of the closure 17,

will be pocket 15.

Two brackets 29- are pivoted at 30 to the inner sides of the bars 8, said brackets carrying two clamping screws 31 for inwardly forcing the strip 26 to tightly engage its flexible diverted and cannot enter the edge portion 28 with the closure 17. The

pivotal mounting of these brackets 29 permits them to swing upwardly to the idle position shown in Figs. 3 and 4 when their use is not necessary, in which position, they will clear the strip 26 and permit downward swinging of the latter. `When the use of this strip 26 is necessary, however, the brackets are swung to the position shown in Figs. 1 and 2 and they thus dispose'the clamping screws 31 for use in holding the strip edgel 28 tightly against the closure 17.

Excellent results are obtainable from the general construction shown and described and such construction is therefore preferably followed. However, within the scope of the invention as claimed, variations may be made and it will be obvious that when the invention is embodied in a door for inside use, the weather strip 26 and associated parts, may be omitted, which is also true of the cowl flange 24, should it be desired to omit suoli ange. Any desired means may be used for locking either of the closures 17 -18 in raised position if desired.

A door comprising a rectangular frame, spaced panels extending between the vertical side bars of said frame in the lower portion of the latter, providing a pocket between said panels, a closure slidable into and from said pocket, said closure extending across the upper portion of the frame when raised, a horizontally elongated strip at the outer side of one of said panels near the upper end of the latter, means pivoting said strip to the side bars of the frame for upward and inward Y swinging to an inclined position over said one panel and over the space between this panel and the closure when the latter is in raised position and for downward swinging to a position at the outer side of said panel, said strip being provided with a flexible edge portion to contact with the closure when the latter is. raised and said strip is swung to said inclined. position, brackets pivoted to the vertical side members of the frame, and clamping screws carried by said brackets for forcing said strip tightly against said closure, said brackets being inwardly and outwardly swingable about their pivots to dispose said screws nor out of yoperative relation with said strip.

In testimony whereof Ihave hereunto afiixed my signature.
