COMBINED BUCK AND Jann Application led August 4, 1928. Serial No. 297,454.

My invention relates to building construction and particularly to a framing element for doors and other wall openings.

An object of my invention is to provide an all-metal buck, jamb and stop of the utmost simplicity and of minimum weight of material.

l have in co-pending a plications for patents illustrated other orms of all-metal frames involving a channel shaped buck and a jamb, stop and moulding, but such construction involves the use of an excess of material over that required in the design now submitted. In the present construction, I have combined the jamb and buck in one element of channel shape which is snugly fitted over the margin of the tile wall thus insuring the utmost rigidity. To complete the required elements, I provide an angular strip Welded to a side ange and sha ed to provide a plaster terminal, groun and moulding.

Separate strips secured vto the inside face of the channel at intervals in the length thereof,

serve the double purposes of providing for a wall anchor and as shims for a hinge block.

The invention will be more readily understood by reference to the accompanying drawinUs, in Whichig. 1 is a sectional view through a frame construction in accordance with my invention2 and applied to a tile Wall, and

Fig. 2 is a side elevation thereof.

In the dra-wings, a tile wall is indicated at A, and plaster at B.

The device of my invention consists of a continuous channel having a web 10 and side langes 11. A stop 12 is formed in the web by displacing the metal thereof into the form shown. The channel is so designed that the ilanges fit snugly over the sides of the tile wall, and as the flanges are continuous the framing member is in effect apart of the wall, the thrusts and blows incident to the door action being transmitted directly to 45 the wall and not into any fastening devices such as nails or screws.

In order to provide a nish around the opening, I utilize L shaped continuous strips, the one shown in the upper portion in Fig. 1 having a foot iange 13 that is weldedto the channel flange 11, and a perpendicular iiande 14 havin a depth corres onding to the designed thic ess of plaster li), the flange terminating in a rebent margin 15 that acts as a plaster anchor. The construction shown in the lower portion of Fig. 1 is similar, having a foot flange 16 welded to the flange 11, a moulded lateral flange 17 and a rebent margin 18. These elements are very simply applied in the shop, being spot-Welded at a few points in the length of the frame.

As a means for anchoring the frame against lateral thrusts I provide the T head anchor 19, the shank of which is embedded in the masonry wall and the head of which occupies the space within the stop 12. Short strips 20-21 are welded to the inside face of the web at intervals in the length of the frame. The inner edges of the strips project across the opening into the space within sto 12 and provide an interlock for the T hea anchor. The strip 21 extends laterally outwardly and has a cutout to correspond to a. cutout 22 in the web of the frame to receive the butt of a hinge.v A hinge block 23 is welded to the strip 21 and serves as a mount for the hinge screws. The strip 21 thus serves as a shim for the hinge block and as a means for forming the interlock for the Wall'anchor.

The part-s as described are all formed and welded in the shop and shipped ready for installation. The corner connection is not shown, but is in the form of a sliding interlock such as described in co-pending applications.

The invention is one capable of considerable modification and I do not wish to be limited asindicated in the appended claims.

I claim: p

1. `In door framing, the combination of a channel shaped member, the ianges of which are adapted to receive the edge of a masonry wall, the web of the channel constituting a j amb, and a continuous angle strip 95 constituting a plaster terminal, ground and moulding welded to the side face of a Hange.l

2. In door framing, the combination of a channel shaped member, the flanges of which are adapted to receivethe edges of a masonry wall, the web of the channelconstituting a jamb, and an L sha ed member one leg of which is secured to t e side of a langeand the other leg of which acts as a.

plaster terminal and moulding.

3. In framing, the combination of a jamb of channel shape adapted to be directly mounted over the edge of a masonry wall and an L shaped continuous strip one leg of which is welded to the outer face of a flange and the other leg of which defines the thickness of and acts as a terminal for plaster.

4. In combination, a channel member, the flanges of which directly engage a masonry Wall and the Web of'which constitutes a door jamb, a hollow stop formed in'said jamb, means for partially closing the back opening into the space Within said hollow stop, an

anchor having a head adapted to enter the space Within said stop and to interlock with said closing means, and a hin e block, said closing means serving as a s im for said block.

In testimony whereof I have afiixed my signature.

ISAAC A. BAUM.
