Jam, 23? Q. J, J, STEFFAN 938,925
DooR JAMB Filed Feb. 13, 1948 INVENTOR. .J.J. STEFFAN BY MW ATTORNEY.
Patented Jan.. 23, 1951 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to door jambs, and more particularly to a novel attachment adapted to form the trim or casing of a jamb for an ordinary door, or for a window in the form of a door having hinges at one side to be attached to the jamb.
In this art, a very strong jamb is required to rmly support a hinged door, but a further requirement appears in providing a trim or casing having the desired durability and appearance in the door frame. Sheet metal, especially aluminum, is quite desirable in door frames, but a metallic jamb strong enough to support a door is likely to be unsightly or expensive.
One of my objects is to conveniently provide for use of any desired material as a firm support for a door, and at the same time employ a highly attractive but relatively weak metallic outer jamb section for the trim or casing. For example, the jamb may include an inner jamb section made of wood, concrete or any other suitable material having the strength to support the hinged door,
while the outer jamb section is composed of du-r rable surfacing material, such as aluminum or other sheet metal, which may be quite thin because it does not have to support the door.
This inexpensive outer jamb section may be a single piece of thin metal shaped to provide theA door stop and all other details of an ornamental trim or casing. In actual practice, an outstanding advantage appears in novel cooperative details whereby the new outer'jamb section conceals the unsightly hinge members which are usually exposed at the jamb. Other interesting details appear at the neat side trim members exposed at opposite sides of the inner jamb section and provided with inturned anchoring margins having recesses for portions of a wall.
With the foregoing and other objects in view, the invention comprises the specific combination and arrangement of details herein shown. However, it is to be understood that the scope of the invention extends to modifications more broadly described by terms employed in the claims hereunto appended.
Fig. 1 is a view of a portion of a wall, showing a door casing provided with an outer jamb section embodying features of this invention, the door and its hinges being omitted.
Fig. 2 is a fragmentary perspective view on a larger scale showing the lower portion of said outer jamb section.
Fig. 3 is a horizontal section on a still larger scale showing said outer jamb section associated with a rm inner jamb section, and a portion of a door hinged to said inner jamb section.
Fig. 4 is a View similar to Fig. 3 illustrating another form of the invention.
Fig. l shows a door frame provided with jambs A and B united with a corresponding lintel C at the top. This view shows the exposed trim or casing members of the door frame which may be made of uniiormly shaped sheet metal with joints at an angle of about 45 at the top. Special attention vvill be directed to the outer section I of the jamb A having hinge-receiving slots 2 shown at upper and lower portions of Fig. l. One of these hinge-receiving slots appears in Figures 2 and 3.
Fig. 3 shows a suitable irm inner jamb section adapted to receive and support the door hinges. This inner jamb section includes a vertical stud 3 united with a hinge-receiving spacer 4. Howe ever, the firm inner jamb section is embraced and concealed by the relatively weak outer jamb section I which forms a trim or casing for the jamb. In Fig. 3, this Weak outer jamb section consists of a thin sheet metal channel having an intermediate web 5 to match the adjacent vertical edge of a door 5, an abrupt extended door stop l at one side of said intermediate web 5, a side trim member extending from said door stop l, and a companion side trim member 9 extending from the opposite side of said web 5.
The side trim member 9 is provided with the hinge-receiving slots 2 at its junction with the intermediate web 5, as shown in Figures l, 2 and 3. rStandard types of door hinges may be employed, each hinge including a member I0 attached to the door as shown in Fig.. 3 and a member l l attached to the inner jamb section. HOW- ever, when the hinge members II are inserted through the slots 2, they will be seated against and concealed between the inner face of the web 5 and the outer face of the rm inner jarnblsection. The intermediate web 5 is provided with ceive the hinge members Il.
holes i2 adjacent to each slot 2 (Figures 2 and 3) for the reception of screws to anchor the door hinges to the rm inner jamb section.
This concealment of the hinge members Il is a very desirable feature in the art of making door casings. The metal of web 5 can be so thin that it will not interfere with proper closing of the hinged door, and it is not absolutely necessary to cut special recesses in the jamb member 4 to re- As a labor saving feature, the slots 2 predetermine the locations of the door hinges, and in actual commercial practice the metallic outer jamb section is conveniently employed as a templet to accurately locate l, the screw-receiving holes in the door 6. Before the metallic frame is assembled, said outer *jamb section is placed on the hinge-receiving edge of the door where the locations of holes for the screws are marked through the holes I2 in the web 5.
terminal anchoring flange I extending therefrom. The ange i5 can be anchored to the rm inner jamb section in any suitable manner. For example, in Fig. 3 I have shown nails i6 as anchoring members. In this View each inturned member i4 has an abutment face at an acute angle to its terminal flange l5, so as to positively anchor marginal edges oi the wall members i3.
e illustrates a jamb similar to Fig. 3, and the same reference numerals have been used for corresponding details. However, Fig. 4 includes a more fim anchorage for wall board, or the like, at opposite sides of a wall. In this view the inturned anchoring margins of the side trim members and 9 are bent to form deep recesses or pockets for edges of wall boards l'f. Each of these inturned margins includes an outer side member 9 arranged parallel with the Wall and bent upon itself to form an inner side member i9, the latter iaving an extension 2G to form the inner wall of the pocket and a terminal ange 2i nailed to a simple vertical stud 22 which provides the inner jamb section. The hinge member i l is inserted through the slot 2 and concealed between the web 5 and the outer face of the stud 22, where it is secured to the stud by 'the usual attaching screws.
Advantages of the invention appear in the single piece or thin sheet metal producing all of the elements required for an ornamental trim or casing, including the door stop, while also con: cealing unsightly hinge members and providing desirable recesses or pockets for wall members at opposite sides of the door jamb.
