MARTIN H. OTTO, OF MINNEAPOLIS, MINNESOTA, ASSIGNOER. T0 WABASH SCREEN DOOR 00., OF MINNEAPOLIS, MINNESOTA.

COMBINATION SCREEN AND STORM DOOR.

Application filed June 7, 1918.

To all whom it may concern:

Be it known that I, MARTIN H. Or'ro, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Combination Screen and Storm Doors, of which the following is a specification.

The object of my invention is to provide improved means for fastening a screen or storm sash in a door to the end that the door can be easily and quickly converted from a storm to a screen door or vice versa.

A further object is to provide a fastening means for the screen and storm sash which will hold the sash securely, eliminate all danger of rattling and at the same time effectually close the joint between the sash and the stiles of the door.

The invention consists generally in various constructions and combinations, all as here inafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is an elevation of a door with my invention applied thereto,

Fig. 2 is a sectional view through the door, showing the manner of mounting the fastening device therein,

Fig. 3 is a side view showing the manner of grooving the door stile and the sash to receive the fastening device,

Fig. 4 is a perspective view of the fastening device taken apart.

In the drawings, 2 represents a door having stiles 3. Openings 4 and 5 are provided in the door where the panels are usually arranged and I have shown an opening at the bot-tom as well as the top though, of course, the one at the bottom may be omitted, if preferred, and probably would be, as there would usually be no necessity for a transparent bottom panel in the storm door, though frequently desirable where screens are substituted for the glass panels. However, this is unimportant, as my invention is applicable to any style of door regardless of how many removable panels may be provided. The stiles are rabbeted as at 6 to form seats for the sash 7 which may contain either glass or a wire mesh, it being only necessary to substitute one for the other to adapt the door for cold or warm weather.

Various devices have been provided for Specification of Letters Patent.

Serial No. 238,649.

fastening these interchangeable panels or conspicuous, the only elements in view being the ornamental head of the screw on the inside of the door and the pocket into which this screw is inserted. There are, as shown, preferably four of these fastening devices with each panel, one at each corner, and the sash is provided with grooves 8 in the edges and corresponding grooves 9 are provided in the stiles of the door opposite the grooves S. I also provide similar grooves 10 in the stiles in parallel relation with the grooves 9 and separated therefrom by a narrow web 11 which is sufficiently flexible to yield under pressure of the fastening device. A plate 12 has a key-hole slot 13 therein at a point midway between its ends, which registers withan opening 14; extending through the stiles of the door transversely of the grooves 9 and 10 and the web 11. At one end of the bore of this opening is a bushing 15, suitably ornamented and concealing the edge of the opening on the inside. At the other end of the opening on the outside is a plug 16 with a rounded ornamental outer end. A screw 17 fits within the bushing 15 and has lugs 18 formed thereon to fit into the ends of the keyhole slot 13 to turn the plate 12 when the screw is rotated and the plug 16 has similar lugs fitting into the walls of the opening to hold the plug against revolution. The end of the screw is tapped into the plug at l9 and when the screw is turned in toward the door panel the plate 12 will be turned down to a horizontal position with one end fitting within the groove 8 in the sash while the other end, bearing on the web 11, will bend it slightly sothat it will have the effect of a spring for taking up any lost motion and causing the sash to be drawns'nugly against the rab'oeted edge of the stile and be held thereon with a yielding pressure. When the screw is turned in the other direction, the plate 12 will be swung to avertical position and be disengaged from the grooves 8 and thereupon the sash maybe removed from the door. This web 11 formed in the door stile provides an inexpensive and convenient means for taking up the wear of the walls of the grooves in the screen or storm sash panels, or expansion or contraction thereof due to atmospheric conditions, the pressure on the web being increased or decreased to obtain any slight variation in the position of the locking plate with respect to its groove in the sash.

, The storm sash and the screen being interchangeable, one may be substituted for the other and by a simple movement of the locking screws the plates 12 may be swung to their locking position in the sash or the screen, and the substitution of the screen for the storm sash easily and quickly e'ifected without the use of any other tools except an ordinary screw driver. The looking plates will be invisible when mounted in the door and the ornamental head 16 will present a neat, finished appearance to the outside of the door and be the only indication on the outside of any fastening means for the sash or that it does not form a permanent part of the door itself.

I claim as my invention:

1. The combination, with a door having a removable panel and rabbeted edges against which said panel is seated and a stile having a vertical groove therein, said panel having a corresponding groove adapted to register with the groove in the stile when the panel is seated therein, said stile having an opening extending transversely of said groove, a screw fitting within said opening, a plate having means for interlocking with the shank of said screw for revolution therewith, the end of said plate projecting into the groove in said panel when the screw is revolved and said plate having a yielding backing in said stile groove resisting pressure of said screw to seat said plate against the wall of said panel groove and compensate for expansion or contraction of the wood.

2. The combination, with a door having a removable panel and a seat formed in the door stiles to receive said panel, said stiles having grooves in their inner edges and said panel having corresponding grooves to register therewith, plates fitting within the grooves in said stiles and having key-hole slots near the middle portion thereof, said stiles having holes extending therethrough transversely of said grooves, screws fitting within said holes and within the slots in said plates and having means for interlocking with said slots for revolving said plates simultaneously with said screws, the ends of said plates projecting into the grooves in said panel for pressing the panel against the seats in said stiles when said plates are revolved.

3. The combination, with a door stile having a seat for a removable panel and provided with inner and outer recesses and a yielding integral web between them, of a plate mounted in one of said recesses and adapted to be moved from an upright position therein to a horizontal position to engage the door panel, and means for moving said plate and simultaneously flexing said web to hold said panel toward its seat with a yielding pressure.

The combination, with a door having a removable panel and a seat formed in the door stiles to receive said panel, said panel having grooves in its edges and said stiles having grooves arranged in pairs with webs formed between them, one groove oi each pair normally registering with the opposite groove in the panel when the door and panel are assembled, plates fitting within grooves in the stiles and seated against the webs therein, one end of the plates being adapted when revolved to enter the grooves in the panel and means passing through said plates and webs for flexing said webs and clampin said panel in said stiles.

5. The combination with a door having a removable panel and a seat formed in the door stiles to receive said panel, said panel having saw slits in its edges forming narrow grooves and said stiles having saw slits in their edges arranged in pairs with yielding webs formed between them, the grooves of said panel being opposite the grooves in said stiles and onegroove of each pair in the stiles being normally in register with the opposite grooves in the panel, plates mounted to revolve in one of the grooves in the stiles and having ends to enter the grooves in the panel, and means for revolving said plates and pressing them against said webs to flex the same and clamp said plates against the walls of the panel grooves.

6. The combination, with a door having a remo able panel and a seat formed in the door stiles to receive said panel, said panel having grooves in its edges and said stile having grooves in its edges adapted to register with the grooves in said panel, plates fitting within the grooves in said stiles, plugs mounted in sockets in said stiles transversely to the grooves therein, screws fitting within said sockets on the opposite side of said stiles and having one end tapped into said plugs and provided with means for engaging said plates to revolve the same when said screws are revolved, the heads of said screws being within said sockets and partially concealed by the walls thereof, revolution of said screws engaging one end of said plates with the walls of the grooves in said panel.

In witness whereof I have hereunto set my hand this 29 day of May, 1918.

MARTIN H. OTTO.
