SHEET-METAL. FRAME.

pplicaton led June 21,

To all l[li/zam, 'it may concern.'

lie it known that I, ERNEST F. JOHNSON, a citizen-ofthe United States, residing at the city ot Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Sheet-,Metal Frames, of which the following, taken in connection with the accompanying drawings, is a slieciiication.

The invention relates to sheet metal trame or trim construction for doors, windows and similar openings; and the object oi' the improvement is to provide a simple and efiicicnt means for attaching the sheet metal structural trim to the wall around the opening, and particitlarly for .holding the simple sheet metal trim or jamb on said wall and so anchored to the same and particularly to the plaster that said plaster cannot part from the edge of the trim or frame, but will y he anchored firmly against the trim for a spaced distance around the same, thereby making a rigid construction to which doors or windows may be hinged or slidably mounted therein; and the invention consists in the novel "features and combinations here-` inaifter set forth and claimed.

ln the drawings, Figure 1 is a perspective view of a portion ot the wall showing the trim in section and one ot the sheet metal anchors in position for fastening in the wall, the other being shown in the attached position in the' wall with the plaster broken away to show the manner ,in which the anchor firmly holds vthe. plaster against the edge oi' the sheet metal trim. Fig. 2 is a sectional View ot' the trim and anchor at line 2-2 in Fig.-5-, showing the plaster extending through the holes in the upwardly extending flanges at each side of the anchor adjacent the edge of the sheet metal trim and for a spaced distance therefrom. Fig. 3 is a perspective view of one of the sheet metal anchors showing its channel shape and anchoring holes and the oppositely extending hooks thereon for engaging the sheet metal trim. Fig. 4 is a sectional view. ot the wall a spaced distance from the sheet metal trim showing the anchor in Sec'- tion with the plaster extending through the openings in the same. Fig. 5 is an elevation ot a door-Way with the brick or tile Wall about the same and/the anchors built into said Wall before said Wall is plastered show- Specificat'on of Letters Patent.

- tachment for the sheet metal frame or trim 11 that the same will be held firmly in posi-l tion against the wall and the plaster against said trim without the alid'oi' the structural trame which is called a buck in the factory. Toward this end a number of spaced anchors 12 are built into the wall. i Said anchors are arranged with barbed or hooked heads to slip onto the inturned flange 13 of the trim 1l at each side, the hookslll being provided at the same angle as the inturned flanges 13 so that said hooks hold firmly against the flanges 13, thereby anchoring the trim 11 firmly in position against the face of the wall 10 around the opening. .y

The anchors 12 are channel shaped in their wall portion and somewhat Wider than the4 brick or tile wall 10 so as to extend out into the central portion of the plaster 15, each of the up-turnedffianges 16 of the channel portion having al series of holes 17 through which the plastery 15 is forced thereby keying or anchoring the anchor 12 firmly in position. A plurality of openings or holes 18 are also provided in the fiat bottom portion of the channel' part of the anchor 12 through which the mortar between the bricks or tiles of the walls 10 is forced, the sheet metal anchor plate 12 being set into the mortar and a portion placed within saidchannel when built into the wall.

One of the main difficulties experienced with a simple trim like the trim or frame 11, as shown, is that thel plaster 15l is apt to separate from the. trim at the point 19 at each side, sincev either the drying of the plaster causes it to draw away from the sheet metal or itsresilience and a knock or heavy pressure upon the same is apt to break and separate the plaster 15 from such a simple trim as the one shown. Accordingly the purpose of the present anchor 12 is to provide a channel shaped portion with the Vianges 16 in the plane of the wallhavv ing a seriesfof holes through .said flanges at each side and extending out a spaced distance from the plaster sheet metal joint 19 around the trim ll. The anchor l2 is embedded in the plaster 1.5 so thoroughly that said plaster is held firmly in position, being anchored against the yedge of the trim 11.

so that it is extremely difficult to separate the same therefrom. As shown in Figs. 1, 2 and 5, the anchors 12 are in spaced relation to 'one another up and down the sides of the trim 11 and so embedded in the plaster 15 that said anchor holds the plaster at each side firmly. the hooks 14 being preferabl \7 made to fit firmly against the inner sides of the trim 11 within the flanges 13 so that said trim cannot resiliently spring inward and break the plaster loose from said trim.

It is apparent that this arrangement makes a very simple yet strong construc-A tion. which is easily built into the wall and trued or adjusted in perfect position, thereb v making it possible to use the simple sheet metal trim shown without additional trim parts or molding.

I claim as new:

l. In combination with a door or window frame, anchor plates having means to attach same at one end to the frame and having their opposite ends extending for a distance beyond the frame, said opposite ends of the anchor plates having vside portions which extend beyond the respective sides of the wall and are spaced from the latter so that the wall plaster will fill the spaces between said side portions and the wall sides.

2. In combination with a door or window frame, channel shaped'anchor plates having means to attach same at one end to the frame and having a width in excess of the thickness of the Wall whereby the sides of the anchor plates will extend beyond the wall sides.

frame and Wider than the thickness of the.

surrounding Wall, the sides of/said channel shaped anchor plates extending into the plane of the wall plaster to hold the same in relation to said frame, said sides of lsaid channel shaped anchor plates having a series of openings therethrough to receive the wall plaster on both sides of said channel sides in anchoring relation through 'said openings to hold the plaster firmly against the edge of said frame.

4. In combination with a channelshaped metal door trim or frame having inwardly extending sides, channel shaped anchor plates for said thereof extending into the plane'of the wall plaster for a spaced distance each side of the wall surrounding said frame to anchor said frame to-said plaster and wall, hooks on said anchor plates engaging said inwardly extending sides to hold said trim or frame in fixed relation to said wall, said channel shaped anchor plates having a series of holes in each ofr the channel sides to receive the plaster therethrough and in the bottom of said channel shaped plate to elnbed in the mortar between the brick or tile of said wall. In testimony whereof I have affixed my signature in the presence of two Witnesses.
