DOOR STRUCTURE.

Application filed June 15, 1925. Serial No. 37,223.

The main object of the invention resides in the provision of a metal door structure of the sealed or weather proofed type which is simple and effective andwell adapted for its purpose with a View toward withstands ing long periods of hard usage without loss of effectiveness. p 1 \Vith this object in View my invention consists in certain features of novelty in the construction, combination. and arrangement of parts by which the said objects and certain other objects hereinafterappearing, are effected, all as fully described with reference to the accompanying drawings and more particularly pointed out in the'claims.

In the said drawings Figure 1 is'a face elevation of a wall in which is installed a door structure embodying my invention.

Figure 2 is an enlarged the line 2-2 of Fig. 1-.

Figure 3 is an enlarged the line 33 of Fig. 1.

Figure 4 is an enlarged the line 4-4 of' Fig. 1.

partial section on partial section on partial section on Figure 5 is an enlarged partial section on the line 5.5 of Fig. 1'.

' Likecl'iaracters of reference'indicate like partsvin the several views. a I 1 Referring to the drawings 1 designates a masonry wall into a suitable opening of which is secured a door frame2.1 A door 3 is'hinged, by m-eansof hinges 4, at one side of the door frame for openingand closing movement with respect thereto, the door be ing provided with a suitable lock 5 whereby.

to rele-asably secure the door inclosed position to theopposite or look side of the frame.

The frame 2 is formed of suitable sheet metal, such as'cold drawnsteel molded to shape, and is of open-sided outwardly facing channel formation. The door '3 is formed of suitablesheet metal such as cold drawn steel molded to shape, and is of box form, the frame and door being provided with intcriorly disposed relatively thick metal pieces 6 secured, as'by welding. respectively to the body of the door and frame at the hinge sides thereof whereby the hinges 4 may be suitably mortised in and secured to,

the door and frame, the piece 6 of the door extending along the bottom ofth-e door and secured thereat for purposes of strength.

The door 3 when closed is disposed within the opening of the frame 2 adjacenta.

face of the frame, and the frame is provided frame in spaced relation therewith in the direction-of opening movement of the door. The pro ecting edge portion of the strip 8 is bent at a right angle toward the frame and spaced therefrom forming. a door stop shoulder, as designated at 9, against which the door engageswhen closed. At the lock side and top of the frame the strip 8 forms, in conjunction with the door frame andmoldmg 7 thereof, an open-sided channel 11 facsee Fig. 5, and extends therealongiimmediately adjacent the'si'de of the molding 7 ading the closed door. 'See Figs. 2 and 4." An open-sided channel 12 is formed from the metal of thedoor at the hinge side thereof,

jacent the door and faces the lock side of the door frame.

The threshold is formed of relatively thick sheet metal, such as cold drawn steel, and is constructed 'as follows. See Fig. 3. One sheet metal member 13 thereof is of right angle section the main leg 14 of which is horizontally disposed on the inside of the door 3 and elevated above the bottom of the door, and the other leg 15 ofwhich" is disposed at the side thereof farthest from the doorand extends downwardly for engagement with a shoulder of the part of the masonry wall 1 forming the'sillof the door opening therein and extending below a floor 16 on the inside of the wall. The edge of the member 13 adjacent the door 3 extends along the face of the door when the door is closed, and a second sheet metal member 17 of right angle 2 section has one ofthe feet 18 thereof secured by rivets 19 against the underor inside face of the horizontal legportion 14 of the member 13-inwardly of and in parallelism with'the aforementioned edge of I the member 13 adjacent the door. The other foot 21 of the member 17 extends outwardly v from said edge of the member 13 immediatev purposes of drainage, this portion beingon till the exterior where the assembly is installed in an exterior wall. A metal strip 22 is secured, as by welding, in the angle of the foot 21 of the member 17 and has its outer surface disposed in the plane of the aforementioned edge of the member 13 whereby to form a stop shoulder against which the inner face of the door engages when the door is closed. By reason of the arrangement of the members 13 and 17 an open-sided channel 23 is formed on the threshold at the stop shoulder thereof and extending therealong and facing the closed door.

Thus is formed an open-sided channel on the door frame and threshold extending around the margins of the closed door and facing the inner face or plane of the closed door at the lock side, top and bottom of the door and facing the lock side of the frame at'the hinge side thereof.

As hereinbefore described the door 3 is formed of sheet metal and is of box form, and a marginal flange 24 is formed on the door at the inner face thereof by portions of the metal of the door being bent on themselves in overlying relation. See Figs. 2, 3, 4, and 5. The flange 24 projects from the said inner face of the door normal to the plane of the door at the top, bottom, and lock side thereof and projects in the plane of the door at the hinge side thereof. hen the door is closed the flange 24 projects into the channels 11, 12, and 23 and engages a packing 25 of suitable material, such as felt, secured in said channels and extending there along, thereby effectively sealing or weather proofing the door opening, the arrangement of the channels and flange as hereinbefore described permitting opening and closing of the door.

It will be observed that a simple and rugged construction is provided which is well adapted for long usage, and that the packing in the channels is protected against accidental damage or displacement. Furthermore the packing is not exposed and is not liable to be affected by weather conditions.

\Vhile I have herein shown and. particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. The combination in a sheet metal door frame and hinged sheet metal door assembly of a marginal flange on the door and formed from the metal thereof and extending along the sides and top at the inner face thereof and projecting in the direction of closing movement of the door at the top and lock side thereof and in the plane of the door at the hinge side thereof, an intermediately disposed inwardly projecting molding on the door frame and formed from the metal thereof and extending along the sides and top thereof, a metal strip secured on said molding and extending therealong and projecting therefrom normal to the plane of the door frame opening in spaced relation vith the frame in the direction of the door and forming a stop therefor and an open sided channel facing the closed door at the top and lock sides of the frame, and an open sided channel formed from the metal of the frame at the hinge side thereof and extending therealong immediately adjacent the side of the molding adjacent the door and facing the lock side of the frame, said flange being adapted to project into said channels when the door is closed for engagement with packing secured therein.
