l. A. `BAUM DOORFHAME Filed March 25. 1929 Patented Dec. 16, 1930 IsAAc A. BAUM, oronraco, ILLINoIs l DOORERAME Application inea march 25, 1929. seriai No. 349,634-

My invention relates to door frames and particularly to an improved buck having numerous advantages hereinafter described.

An object of the invention here described is to providea metal buck adapted to receive nailing blocks for supporting a j amb, the

construction being such that added strengthand stabilityaresecured. These advantages are present by' reason of peculiarities in design; for example, the depth of the channel-y shaped buck is reduced, thereby reducingthe distance between the jamb and the edge of the masonry wall. This lessens the extent of overhand and shortens the leverage tending to separate the buck from the wall unde laterally exerted blows. Y

The rigidity of the structure is increased also by providing a double thickness of metal at the sides of the channel. The strength of the channel is also increased by eliminating cutout portions ordinarily provided in the web of the channel, the lateral positioning of the channel being secured by means of continuous strips.

By reducing the depth of the channel, the size of the wood blocks is correspondingly reduced with a savin of material.

Additional strengt against lateral blows is provided byv utilizing continuous strips from top to bottom of the channel vinstead of the usual ears arranged in spaced relation.

Inasmuch as the projecting or exposed portions of the buck should be painted and as paint will not adhere to black or blue iron sheets, it is essential that these portions be galvanized or similarly coated. By reason of the construction shown the channel member i stood by vreference to the accompanying drawings, in which Fig. 1 is a perspective sectional view of a frame arranged in accordance with my in- W vention; i

through; and, f

Y lF ig. 2is a transverse sectional view there- 'g. 3 is-a .fra mentary sectional view of a modification of the construction. d

Inv the drawings, themasonry `wall is indicated at 10, the jamb at 11 and the wood nailing blocks at 12.7. rIhe buck is of channel form comprisinga ,web '.613 and flanges 14. The margins 15 of the Aflanges project `at right nangles'and constitute plaster terminals. The .channel portion maybe formed of gal-l vafizedmaterial `toadapt the exposed portionsl .to receive paint;` l

- placedasshown and welded tothe -flanges of '55 Chnnelf I -pNlails 17 project through the two thicknesses of metal .and hold the wood blocks. Other nails 18 are used for securing the-jamb tothe nailing blocks. i

The strips attheir'rearward edge project asubsta-ntial,distance beyond Vthe limits of thewchanneland'closely lit the masonry wall. As a n ieanslfor anchoring the plaster to the strips, I strikeout loops 19,ithese being ar ranged in suitablefclosely spaced relation to accomplish the desired result. Wall anchors i 20 having hooked ends that engageinthe apertures V`formed by striking ,out the loops, serve to hold the structure in place.

Inthe modification shown in Fig. 3 the so buck comprises a web 21 and flanges 23 which may be formed of black iron, the strip 23 has the margins 24 forming a plaster terminal and may be of galvanized metal. Otherwise the construction is the same and the function is the same as that already described.

Obviously the construction is capable of some modication and I do not wish to be limited except as indicated in the appended claims.

I claim:

1. In frame construction, the combination .of a channel shaped buck, and a continuous strip welded to a` iiange of the channel and extending readwardly a substantial distance L beyond the limits of the channel in line with the flange, and plaster anchors formed in said strip. y

2. In door frame construction, the combination of a buck of relatively shallow chanlo nel construction, adapted to he mounted with the flanges projecting into the door opening, a wood member in the channel adapted to receive a jamb, and a flat, longitudinally continuous strip permanently secured to the outer face of a channel flange with the inner edge of the strip projecting a substantial distance beyond the limits of the channel and adapted to lie alongside of a wall.

3. In a door frame, the combination of a relatively shallow channel with the margins of the flanges bent to provide plaster terminals, and longitudinally continuous flat strips welded to the outside iac'e's of the flanges of the channel and projecting rearwardly from the limits of thel channel.

4. In a door frame, the combination of a relatively shallow channel with the margins of the flanges bent to provide plaster terminals, and longitudinally continuous flat strips welded to the outside faces of the flanges of the channel and projecting rearwardly from the limits of the channel, and plaster anchors formed in said strips;

5. In a door frame, the combination of a relatively shallow channel with the margins of the ia'nges bent to provide plaster terminals, and longitudinally continuous flat strips welded to the outside faces of the flanges of the channel and projecting rearwardly from the limits of the channel,` and loops struck out from said strips to serve as plaster anchors.

6. In a door frame,V the combination of a relatively shallow channel with the margins of the ilanges bent to provide plaster terminals, and longitudinally'continuous flat strips welded to the outside faces of the flanges of the channel and projecting rearwardly from the limits of the channel, Vwoodumembers in said channel and a j amb secured to the wood members.

In testimony whereof I have aiXed my signature.

ISAAC A. BAUM.
