UNITED STATES ISAAC A. BAUM, OF CHICAGO, ILLINOIS. i

DOORFRAME.

Application filed April 27, 1928.

My invention relates to building construction and particularly to a. novel buck and jamb arrangement involving the use of a metal buck and a Wood j amb suitably joined thereto.

In construction of the described type, it is customary to provide a metal buck of generally channel shape, the channel being open toward the door opening, a plurality of Wood blocks being seated and secured in the channel to provide means for attachment of the j amb. Notwithstanding the most careful fitting of the jamb and molding to the rough buck, there will be points in the length of the l'rame Where a through opening cannot be avoided and consequently light and air Will pass through said opening. This is particularly liable to occur at points between the Wood blocks, at which points there is no filing between the metal buck and the amb.

My invention contemplates the employment of simple means that Will obviate the possibility ot' any open space between the metal and Wood members through which light and air can pass.

My invention will be more readily understood by reference to the accompanying drawings, in which- Fig. 1 is a sectional view through a buck and jamb arranged in accordance with my invention Fig. 2 is a perspective view of a buck and wood block;

Fig. 3 is a sectional view through a modified form of my invention, and

Fig. Ll is a perspective view of the construe tion shown in Fig. 3.

In the drawings and referring particularly tov F igs.v 1 and 2, I have illustrated a metal rough bucl; in the form of a channel having a web 10, llanges 11 and plaster terminal flanges 12, terminating in rebent margins 13 serving as a plaster anchor. A Wood block 14 is seated in the channel, a plurality thereof being preferably employed, in spaced relation. The thickness of the block in this construction must be less than the depth of the flanges of the channel, thereby leaving a recess or pocket to receive the continuous projection 15 from the jamb 16. In other Words, by making the block of less depth than the buck flanges, the jamb is compelled to enter Serial No. 273,305.

and occupy a space Within the limits of the flanges and thereby to etlectually prevent the passage of light transversely through the joint. Preferably the jamb has integral molding 17 that snugly fits against the flanges l2 of the buck. In order to insure a perfect fit against the face of the flanges 12, I preferably proportion the Wood block so that a small space is provided between it and the corresponding face of the jamb. The construction described provides an extremely simple means of accomplishing the purpose and provides an especially desirable arrangement from a construction standpoint.

In the construction shown in Figs. 3 and 4l the buck is identical with that already described. It has, however, in addition t0 the elements described a continuous flat strip of metal 16 Welded to the inside face of one or both of the flanges 11 of the channel and project-ing a substantial distance outside of the limits of the flanges. In this construction, the wood blocks 19 are shown as projecting outside of the limits of the channel, although this is a matter of unconcern to the builder. At any rate the jamb 20 is directly abutted against the block and suitably nailed thereto. Thereafter the molding 21 is placed in the position shown, overlying the metal strip and serving to finish the opening. Obviously an integral 'j amb and molding could be used by providing a longitudinal kerf at the point 0f register With the strip 18 in which case the wood block would of necessity be of less thickness than the depth of the flanges. The construction shown will, however, adapt itself most readily to installation by the ordinary carpenter. If desired the strip 18 may be provided on both sides, thereby insuring the accurate placing of the jamb. In either case the strip serves to el'eet-ually exclude the passage oi' light and air through the Wall at the joint.

Obviously other modilications than that shown may be made without departure from the spirit of my invention.

I claim:

1. In building construction, the combination of a channel shaped buck, a Wood block secured therein, the thickness of which is less than the depth of the flanges of the channel, and a jamb secured to the Wood block and having a substantially continuous portion projecting into the channel, whereby the oint between the block and junib is Within the liniits of the flanges..

2. In building construction, the combina- 5 tion of a channel shaped buck, zi Wood block securedv therein, the thickness of which is less than the dept-h of the flanges of the channel, and a. combined janib and molding secured to the block the janib having a continuous portion projecting into the channel whereby Jdie joint between the block and said portion is Within the limits of the flanges.

In testimony whereof I have ailixecl my signature.

ISAAC A. BAUM.
