DOOR.

Specification of Letters Patent. Application filed March 9, 1912.

Patented Feb. 3, 1914. Serial No. 682.825.

do it known that'l. (HARLES Moscn, a subjer-t. of the Emp ror of (tel-many. residing at lortland in the eounty of hlultnomah and State of Oregon. have invented certain new and useful ltl|])."t)\tt)h3ltl in Doors. of \\'l)l('il the following is a --peeiti('atiou.

This invention relates: doors. and the primary tion is to provide a door-which may be utilized either as a solid panel or glazed door in Mold weather or may be utilized as a screen door in hot weather, without being removed from its hinges.

secondary objeet of the invention to provide a slidahle panel or door member and simple and etticient means for operating the said panel and holding it in its, raised position.

A further objeet of the invention is generally to provide a door which will be neat. in appearance and which will be strong and durable and inexpensive to produee.

The invention is fully illustrated in the accompanying drawings and will he'hereinafter deseribed in detail. the novel features of the same being -.ul. sequently pointed out in the appended claim. a 1

in carrying out myinvention. l unploy 2 frame eonsisting of the stiles l and the uppe and lower rails 2 and 3 and intermediate bar 4 connecting the stiles. The inter mediate bar-t is reeessed at its ends as shown by dotted lines in Figs. '1 and l. and holding or retaining stripe 5' are secured to the stiles and extend aeross the rails and the. said intermediate bar so as to impart a some;

to improvements in l t i 'in the lower edge of the rail and the side as the same is wound upon the shaft.

in the frame. and the lower edge of the what ornamental appearance to the door and also to permit access to the operating parts as will he presently set forth. These several retaining strips are secured to the door trame by Screws (3, preferably, in order that; the removal and replacing of the bars will not cause undue injury to the material of which the frame is made. The lower portion of the frame, that is to say, the part between the lower rail 3 and intermediate bar 4 may be finished in any desired manner to present a solid panel 7 while the portion between the intermediate bar and the upper rail isle ft open to be covered by a sliding panel hereinafter more particularly described.

The inner or facing edges of the stiles are provided longitudinal grooves S in which the operating cord or ea ble 9 plays, the said word 75 etmstituting an endless belt passing arsamd pulleys 10 mounted in reeesses l1 near the lower ends of the stiles and similar pulleys 12 secured rigidly on a shaft or winding rod 13 which extends through the upper rail and is journaled in bearing plates 14 secured in recesses 15 nea' the upper ends of the stiles. The upper rail is provided with a longitudinal recess or cavity or chamher to to aeetmnnodate a shaft or winding rod 13 and a sereen 17, preferably of wire nettingis secured to the said shaft or winding rod and adapted to wind upon or unwind therefrom in the operation of the invention. A longitudinal slot 15 is formed 0 walls ol,tl1e said sl. diverge upwardly, as shown at 1!) in Figs. 2. and 3, so as to accommodate the inelined position assumed by the downwardly extemling portion of th'e sereen I he lower edge of the said screen is secured to a sliding panel or frame 20 which is mounted between the stiles 1 and adapted to move downwardly through the intermediate bar 4 and into a ehamber 21 formed behind the lower panel 7, as will he readily understood upon reference to Figs. 2 and 3. This panel or frame 20 may be equipped with an orna mentalbolid opaque plate. but is preferably glazed. a pane of glass being indieated in the drawings. The pane f2 is seeured within the frame by means of molding strips 23 fitting against the pane and upon rabbets formed sereen 17 is seeured in the upper edge of the said frame 20 by means of a molding strip 24 in a similar manner, as clearly shown. The upper retaining strips 5 extend over the chamber 16 in the rail so as to protect the same against the entrance of dirt and provide removable covers for the said chamber so that access to the parts may be readily had when necessary.

Molding strips 25 are secured to the lower edge of the rail and spaced apart so as to furnish a groove or recess to receive the upper edge of the slidable panel when the same is raised and the lower edge of the rail constitutes a. stop to limit said upward movement, allof which will be readily understood upon reference to Fig. 2. Similar molding strips 26 are secured upon the upper edge of the intermediate cross bar 4 to form guides for the sliding panel as well as to impart a neat and ornamental finish to the door and additional similar strips 27 are secured to the inner edges of the stiles so as to constitute guides for the panel during its movement. Pivoted upon the inner face of the intermediate bar 4, at or near the upper edge of the same, is a. latch 28 which, when the sliding panel is raised, is adapted to swing into the position shown in Fig. 2

whereby the inner end of the latch will pr0- ject under tlre panel and consequently support the same in its raised position. When it desired to lower the panel the free end of the latch is swung downward so that the latch will. be disengaged from the panel, as will. be readily understood on reference to Fig. 3, and to prevent excessive wear upon the upper end of the panel when the same is in its lowered position, I secure thereto a metal strip 29 against which the end of the latch will hear so that the pressure then exerted by the latch will not indent nor mar the ppnel. The panel is connected to the operating cable 9 by a screw 30 which passes through the cord 9 so that the move- -ment of the cord will necessarily be imparted to the panel, and to prevent mutilation of the cord or belt by the screw a reintorcing sleeve or ring 3i is fitted around the same at the head of the screw. In the side members of the panel 20 and. in the inner faces of said side members, I provide handles or pulls 32 which will furnish a (fOllVQlllUllli means-"of grasping the panel when it desired to raise or lower the same. When the panel is in its lowered position the upper handles or pulls 32 will lie di-.

rectly behind the recessed ends of the intermediatcbar l so that if the intermediate retaining strip 5 be removed the handles may be reached and sutliciont force applied thereto to move the panel upwardly so that its edge will project above the intermediate bar. The panel may then be readily grasped so that it may be quickly raised to the limitof its upward nu'wement'.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the use and advantages of my improved door will be readily understood and appreciated. ln cold weather the panel. will be in its uppen most position, indicated in Fig. 2. When the weather becomes hot or, for any other reason, outside air is desired in the room, the latch 28 is depressed and the panel then lowered into the chamber 21, its impact against the bottom of said chamber being cushioned by rubber or other elastic lnifl'ers 33 therein, so that damage to any part of the door through dropping or too rapid lowering of the panel will'be avoided. To further guard against damage from this source I may provide triangular metallic plates 34 at intervals along the meeting edges of the panel and the lower portion of the stileso that'the contact between the overlapping points of said plates will check the descent of the panel. The upper por tion of the stile will be beveled to avoid the wearing away of the same by the plates on the panel. As the panel is lowered it will, of course, pull. downwardly upon the screen 17 so as to unwind the same and draw it across thespace being vacated by the panel so that when the panel reaches its, lowermost position the upper portion of the door will be screened to prevent the entrance of flies or other insects but permit thorough ventilation. The belt or cable 9 will follow the movement of the panel and by its engagement with the pulleys will tend to retard the descent of the anel and also will cause the screen to unw nd evenly so that .wear upon the walls of the slot 18 will be minimized. In raising the panel, the screen would tend to buckle between the upper edge of the panel ind the upper rail 2, but this buckling is av iided by the provision of the cable or belt 9 which will positively actuate the shaft or winding rod 13 and thereby cause the screen to wind evenly and smoothly thereon and at a speed determined by the movement of the panel.

it will be readily noted that my improved door is not bulky and that all the operative parts are inclosed in the frame of the door so as to be protected against injury, and as there is no'con'iplicated mechanism con nected with the door the operation will. be

easy and frequent repairs will be unnecessary.

It will be understood, of course, that while l have shown and described the invention .valllillllll taining strips attached to the stiles and extending below the lower edge of the upper rail I ing chamber,

to fo'rln-ascreen receiving chamber, outer and inner panels supported upon the lower rail and defining asash receiving space, a slidable panel vertically movable in said space, a winding shaft disposed in the screen receiva'screen attached at one end to said winding shaft and at the other to the upper edge of the sliding panel, oppositely disposed pulleys mounted. upon the windin shaft, oppositely disposedpulleys mount in recesses in the inner faces of the stiles and below said panels, an endless flexible connection passlng over.each pair of upper and lowerpulleys and through the longitudinal groove of the stile, and a connection between one flight of each endless connection and the slidable panel, the-pulleys being greater in diameter than the width of the groove the flexible connection pass whereby to frictionallyretard the movement of the flexible connection.

In testimony whereof Iafli'x my signature in presenceof two witnesses. CHARLES MOSOH. 11. SJ
