WALL CONSTRUCTION 3 Sheets-Sheet 3 Filed Sept. 29, 1 956 INVENTOR ATTORN EY Patented July 26, 1938 UNITED STATES PATENT OFFICE 12 Claims.
This invention relates to wall structures and particularly to a structural frame device to be incorporated in wall structures for framing doors and windows, and for providing molding, splash panels and composite post structures.
One of the principal objects of the present invention is the provision of a frame device which may be incorporated into the wall so as to form substantially an integral part of the wall structure and which, when incorporated into the wall, provides framing for windows and doors, molding, and splash panels which are substantially flush with the finished wall structure and have no exposed dust collecting shoulders.
Another object is to provide a frame device which may be utilized without any appreciable changes in form and construction, for these numerous purposes, as a result of which special frame and panel elements, parts, fittings and the like may be eliminated.
Another object is to provide a structural frame device which is; decorative, in which the means" connecting the same to the wall structure are concealed, and which, at the same time, provides a suitable conduit for wiring and the like.
Another object is toprovide a device of this character which affords a striking guide orgauge for plaster coated walls such that an accurately finished surface may be obtained and the edges of the plaster coating are held securely in place.
Other objects and advantages will become apparent from the following specification wherein reference is made to the drawings, in which:--

Fig. 8 is a horizontal sectional view through a ment of the structural frame device showing the door frame illustrating another application of the device.
Fig. 9 is a horizontal sectional view of a wall illustrating a molding member for connecting a plaster wall to a wooden wall. 5
Broadly, the frame'device comprises generally a supporting member and a cooperating trim member, the supporting member being fixedly incorporated in the wall structure so as to terminate flush with the finished wall surface and detach.- 10 ably receiving the trim member in a. manner such that the trim member likewise lies substantially flush with the finished surface of the wall and conceals the connections between the wall and the supporting member.
Referring particularly to Figs. 1 to 4, the use of the device in connection with a plaster coated wall W for providing a horizontal molding, a base or splash panel, and wall surface panels is illustrated.
The supporting member I may comprise a single sheet of metal bent or formed between its lateral margins to provide a readily accessible channel having 'a base 2 and flanges 3 which are curved and convex toward the interior of the 25 channel. Beginning near the outer or free end portions t of the flanges 3, the sheet metal is curved more abruptly so as to extend back toward the plane of the base 2, and lie generally parallel to and spaced from the flanges 3, thus providing a 30 double walled flange, the outer walls of which provide anchor portions 5. The outermost margins of the sheet ,of metal are then bent to lie in the plane of the base 2, providing supporting fins 6. Each of the anchor portions 5 is pro- 35 vided with a longitudinal corrugation or concavity I, for purposes later to be described.
The trim member I 0 comprises a single sheet of metal having portions folded back on itself part way toward its mid-portion and then outwardly 40 to provide a generally channel-shaped cross section having a base I I and flanges I2. The flanges I2 are concave outwardly and are adapted to spring in between and lie in juxtaposition with the flanges 3 of the supporting member I. The 45 flanges I2 extend only part way into the supporting member I but firmlyv secure the trim member ID in place with the outer surface of the base I I lying substantially flush with the finished wall surface. The width of the base II is preferably 50 such that it overlies and conceals the portions 3 and 4 of the supporting member I when the trim member III is snapped into place therein.
For the purpose of illustration, the frame device is shown ln Figs. 1 to 5 in connection with a lath and plaster wall. Referring particularly to Fig. 5, a plaster wall comprising a plaster coat I5 trowelled onto the usual wood lathing I6 is shown incorporating the device as a molding. In such an installation, the fins 6 and the base 2 of the channel are'secured to,.the laths I6 by suitable nails so as to mount the supporting member in a horizontal position. The frame member is of such dimensions that when so mounted the ends of the flanges 3, outermost from the lath I6, such as the portions 4-, lie in the plane of the outer surface of the finished plaster wall, as indicated at II. The dimension of the portions 3 and 5, normal to the base 2, are preferably of standard thickness of the plaster coat is so that the supporting member I provides a suitable gauge for the plaster finish.
Similarly, as illustrated in Fig. 1, one of the supporting members I may be used for the splash panel near the base of the wall. These rigid members being of proper dimension and. installed carefully, they provide striking guides for gauging the depth of the plaster coating I5. In most instances, also, some of the supporting members I are placed vertically to panel the wall. Thus the wall is divided into a plurality of sections offrames, each frame being entirely enclosed by the supporting members I which are of equal depth normal to the plane of the wall.
Since the members I are of the depth of the plaster, a single striking tool may be moved across the surface of the members to strike the plaster off fiush with the outer end portions 4 of the flanges 3, thus assuring a true and accurately finished wall surface.
Due to the concavities 1, the plaster coating I5 molds readily thereinto and is constrained from warping outwardly adjacent the supporting member I and from becoming detached therefrom due to shrinkage of the plaster while setting.
After the supporting member is installed in this manner, it is only necessary to snap the decorative trim member I into' place therein, thus concealing the supporting member entirely and providing a decorative panel substantially flush with the finished surface of the wall.
When such a structure is used as a molding and it is desired to hang pictures and the like therefrom, it is only necessary to install the usual thin metal picture hook I8, as illustrated in Fig. 5, before snapping the trim member 20 into place, the picture hook used being relatively thin metal so as not to holdthe trim member Ill out to any appreciable degree from the outer surface 'of the finished wall.
As mentioned above, due to the channel-likeconfiguration of the supporting member and the fact that it is closed by a metallic trim member II), a suitable fireproof conduit is provided in which door bell wiring, light cords, and the like may be carried, especially when the device is used for a splash panel at the base of the wall.
In the case of the base panel, however, it is usually desirable that a larger size of the members I and Ill be utilized, but in such instance, the dimension normal to the plane of the wall remains the same and equal to the depth of the plaster coating.
When both horizontal and vertical supporting member. The adjacent fins 6 of the members thus overlie each other and may be held with common anchor means or nails. The trim'members I0 then may be snapped into place so that the lateral edge of one abuts the end of the other so that the horizontal and vertical panels lie substantially in the plane of the wall with no appreciable crack therebetween. Obviously, panelled frames thus provided have no exposed and dust collecting shoulders.
In some instances, the anchor portions of the flanges may be differently configured, depending upon the use. Referring to Fig. '7, for example, a supporting element 2| is utilized at a wall corner, wherein a wood wall joins a plaster or other wall, extending at an angle to the wood wall. In this instance, the plaster coating of the wall, indicated wall 22 is slightly differently cooperated with the member 2|. For example, this wall is provided with a longitudinally extending slot 24 which snugly embraces the protruding portion of the member I formed by the juncture of the flange 3 and base 2, asindicated at 25. Instead of providing the outer anchor portion 5 between the flanges 3 and fins 6, the outer margin 26 of the flange 3 is bent substantially parallel to the wood wall surface so as to fit into a suitable groove in the end of the wood wall portion.
The member 2| may be secured to a corner post 21 by nailing the base 28 and fin 29 thereof to the post in the manner described in connection with the lathing. The trim member then snapped into place, as described.
Referring next to Fig. 8, a vertical section through a door frame is illustrated. In this form, each of the supporting members 3|, corresponding to the members I; is secured to a corner or end post 32 by suitable screws 33, as illustrated. Instead of the marginal fins 6 and the portions 5 and I, heretofore described, being provided at both edges of the members 3|, the metal of one of the elements 3| is bent, at one margin, as indicated at 34, to form a sheathing for the end of the wall and the usual door stop 35. The corresponding margin of the other element 3| is bent to extend parallel to the portion 34 of the other,
element, as indicated. at 36, and forms a continuation of the, sheathing beyond the stop 35. Each ofthe supporting members 3I- receives a trim member in the usual manner, thus providing a door jamb which is substantially the same Width as and substantially flush with opposite faces of the partition wall. If desired, however, for providing'such a door frame, the two supporting members 3 I together with the portions 34, 35 and 36 may be formed integrally with each other.
Referring to Fig. 9 a molding member for connecting a' plaster wall 40 to a wooden wall 4| is illustrated. In this form of molding member the element 45 is formed of a single piece of strip metal and having portions folded back on themselves intermediate the ends of the said strip, and then each end of the strip bent downwardly to provide a substantially T-shaped member having a tongue 46 which is driven into the wooden wall 4| and attachment portion 41' which lies along the edge of the wooden wall and may be secured thereto by means of suitable nails or screws.
In this form the molding member is first secured to the wood wall and then the plaster wall is applied and brought substantially flush with the outer surface of the molding member in order that a substantially fiat uniform wall surface may be obtained.
It is apparent from the foregoing description that the devices illustrated may be used conveniently for the purposes suggested and other purposes, thus effecting a substantial saving in the cost of wall structures by elimination of special parts and fittings. Furthermore, since the supporting members are fully concealed, they may be made of relatively inexpensive metal, the more expensive and decorative metal or finish being necessary only on the trim members.
