Application filed August 8, 1917. Serial No. 184,993.

To all whom it may concern Be it known that I, OTHO M. O'r'rn, a citizen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Sheet-' Metal Structures, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to sheet metal frames for doors and similar openings in which the sheet metal has to be securely attached to the wall around the opening; and the improvement consists in providing a sheet metal frame with means for securely attaching the same to a wall around an opening by means of the plaster and also by means of hinged adjustable sliding anchors which may be turned to the vertical-position for shipmentand to the horizontal. position for anchorage in the wall as, for example, in the mortar between layers of brick or tile; and the invention consists in the novel. features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is an elevation of a sheet metal door frame with the, anchors in the folded position for shipment, the horizontal anchoring position being shown in dotted line, to which position the anchors drop when released from the shipping crate. Fig. 2 is a perspective elevation of one of the slotted adjustable holding plates through which the anchor is hinged, and for the sides of the channel shaped frame, the sheet metal frame being shown in dotted outline with the holding plate in position'therein. Fig, 3 is a sectional view of a portion of the frame and one of the anchors in the anchoring horizontal positionand supported upon its holding plate, the vertical or folded position being shown in dotted line. 4 is a perspectlve view of one of the sheet metal anchor plates as shaped by suitable dies from asingle piece of metal, and Fig. 5 is a perspective view of a similar'shaped'anchor plate built up of pieces of metal. Fig. 6 is a top plan view of one of the anchors in position, the wall engaging portion of the anchor being partially broken away and the holding plate and a'portion of the frame or jamb being Fig. 7 is a perspective view-of a portion of the inner side of the door jamb or frame with the anchor holding plates thereon showing the holding lugs for said plate as struck up from the sheet metal, otherwise giving a positive outline of the construction shown in Fig. 2. Fig. 8 is a crosswise sectional view of the door frame with the edge portion of the door in section thereagainst,and showing modifications of the construction of the anchor holding plates; and Fig. 9 is a perspective view of a further modification of said anchor holding plate. Fig. 10 is a perspective view of the inner side of a portion of the door jamb or frame showing modifications or different forms of blister or lug construction for holding the crosswise anchor plates within a limited space of adjustment on the frame and also for engaging the mortar. Fig. 11 is a sectional View of a portion of a tile built wall with the mortar on the opposite sides thereof showing its anchorage in the flanges of the sheet metal jamb or frame, with the crosswise anchoring plate in dotted line and the edge portion of the door in position against the jamb.

Like characters of reference'refer to corresponding parts in the several views.

The numeral 10 designates the sheet metal frame for a door, window or similar ,0 ening, which frame is made in channel orm with the sides 11 and inturned flanged edges 12 which incline toward the inner wall of the channel and away from the wall of the opening.

The inwardly inclined flanged edges 12 support thereon in slidable adjustment the anchor holding plates 13, preferably between .the struck out lugs 14 in order to space said anchoring plates 13 and at the same time permit their adjustment to the joints in the wall as the same is built up around the frame 10. The struck out lugs 14 may be made in different forms, as shown at 14:, 15, 16 and 17 and attain the purpose though the outwardly projecting dovetailshaped' lugs 14 are preferred since the body of the lug projects into and is surrounded by the mortar and assists in anchoring the side 11 of the sheet metal frame wall and at the same time provides an opening 18 through which the mortar 32 is forced, thus binding or interlocking with the wall when the plaster 32 hardens.

It is obvious tothe correct construction of a door or window jamb that its sides should be plumb. Accordingly the cross holding plates 13 are placed at spaced intervals along the inner side of the frame 10' against the serving the double purpose of holding the sheet metal sides 11 in correct spaced rela. tion from one another and at the same t1me providing in the lengthwise slot 19 an opening through which the end of an anchor plate 20 may be inserted. In order that the anchors 20 upon each side of a door frame 10 shall occupy as little space as possible during shipment they are made to fold ver tically against the outer sides of the frame 10 so that they will drop into the horizontal position for anchorage in the wall as soon as released from the shipping crate and placed upright.

The anchors 20 are made in the angular form to hinge them to the frame 10, a brace 21 being struck out from the sheet metal or attached thereto to hold the anchor 20 firmly in said angular form. The upper end of the angular portion 21 is turned in lugs 23 and 24: when made from one piece of sheet metal,

or when built up from several pieces as:

shown in Fig. 5, the lugs 23 and 24 may be continuous across the end of the angular anchor plate. The Wall portion 25 of the anchor preferably widens out dovetail shaped, and its sides are preferably turned in angular flanges, thereby'giving a shallow channel shape to the portion 25 which when filled with mortar firmly anchors the end 25 in the wall giving great rigidity to the frame 10.

It is apparent that the lugs 23 and 24 may be inserted through slot 19 of the an chor holding plate 13 before the lug 24 is turned into its holding position, being bent upward after said insertion so that the lugs 23 will hold against the inner side of the holding plate 13 below the slot 19 when the anchor 20 is in the folded position and the lug 24; will hold against the inner wall of the cross plate 13 above the slot 19 when the anchor 20 is in the horizontal position for anchorage in the wall, thus providing the limited hinge movement desired for the anchors 2 0 and at the same time permitting them a sliding vertical adjustment upon the frame: 10, the ends of the plate 13 being formed with the lugs 26 and 27 for engag ing on the opposite sides of the inwardly extending flange 12. The anchor holding plate 13 is preferably made with the top and bottom flanged edges 28 to stifi'en the same and at the same time provide a channel construction which holds more firmly in the plaster when built into the wall. Said fiangesare-usually shaped as shown at 28 in Figs. 9 and 10 though they may be given the modified form as shown at 29 in Fig. 8 in which the flange edges 29 extend out over the inturned flanges 12 and perform the ofiice of the'lugs 26 in holding the plate 13 upon the flanges 12.

It is also apparent that a narrow holding bar as shown-in the modified form 30 may be used though not as strong or serving as good a purpose in holding-the anchors 20.

It does, however, keep the channel sides 11 of the frame 10 from spreading and combined with the plaster holds the frame sides 11 in line thereby partially attaining my purpose though not as efiiciently as by the slotted holding plate 13. lhe ends 31 of the plate 30 are inserted through the openings 18 and bent toward one another to form a strong hooked holding construction.

The bent out loop 15 or blister 17 or turned corner 16 form projections which limit the sliding adjustment of the plate 13 and also provide openings through which the plaster may be inserted to assist in the anchorage of the frame but they do not provide the anchoring projection into the mor-- tar which enlarges outwardly thereby forming a strong holding attachment as in the case of the struck'up lugs 14.

I claim as new 1. In combination with a channel shaped metal frame having inwardly extending sides with the outer edges thereof free, a cross bar having its ends formed with angular parts to engage over said outer edges of the sides, so as to prevent relative spreading of the latter, said sides having their free edges provided with slits and the metal to one side of the slits being bent outwardly and displaced therefrom to engage and support said bar and to extend into the mortar.

2. In combination with a channel shaped metal frame having inwardly extending sides with the outer edges thereof bent inwardly at acute angles free, a cross bar having'its ends formed with angular parts to engage over the inner and outer faces of said outer edges of the sides, so as to prevent relative spreading of the latter, said sides having slits therein and the metal adjacent the slits being displaced so as to project outwardly from the sides to engage and support the bar and to also extend into the mortar, the slits in) also forming openings to receive the mortar.

3. In combination with a channel shaped metal frame having inwardly extending sides, a cross plate having a pair of longitudinally extending slits at each end thereof to form-lugs, the lugs on the outer sides of the plate being bent outwardly and the central lug being'bent inwardly in the opposite direction so as to receive the frame sides between the lugs.

4 In combination with a channel shaped metal frame having inwardly extending sides, a cross plate having a pair of longitudinally extending slits at each end thereof to form lugs, the lugs on the outer sides of the plate being bent outwardly and the central lug being bent inwardly in the opposite direction so as to receive the/frame sides beiii slits being displaced to project outwardly and engage the lugs on the adjacent side of the bar. I i

5. In combination with a channel shaped metal frame having inwardly extending sides, a longitudinally slotted cross plate connected to said sides, anchor plates, and means to hingedly connect the anchor plates to the cross plates consisting of a member extending outwardly from the anchor plate at substantially right angles thereto and adapted to engage the front face of the cross plate to hold the anchor plate at an angle thereto, a lug extending parallel to said member to engage the inner face of said cross plate and a lug extending at an angle to said member to engage the rear face of said cross plate to limit the upward movement of the anchor plate when the latter is folded to lie in inoperative position.

6. In combination with a door or window frame, anchor plates, means to connect said plates to the frame comprising a hinged oint to permit folding of the plates against the frame for shipment and to permit unfolding of the plates to lie at substantially right angles to the frame, and means to hold the plates against downward movement when at right angles to the frame.

7. In combination with a channel shaped metal frame havin inwardly extending sides, a longitudinally slotted cross plate connected to said sides, anchor plates, means borne by the anchor plates and engaged in the slots of the cross plates to provide a hinge connection between the anchor plates and the cross plates so as to permit the anchor plates to fold against the cross plates, and means to limit the downward movement of the anchor plates upon unfolding of the latter so as to hold the anchor plates at substantially right angles to the cross plates.

8. The combination of a channel shaped door or window frame, lengthwise inturned inwardly inclined flanges along the opposite edges of said channel shaped frame, holding plates having a lengthwise slot therein, oppositely turned lugs on the ends of said hold ing plates to slidably engage said inturned flanged edges, spaced projections on said inturned flanged edges to space said holding plate, angular dovetail shaped anchor plates having flanged edges to hold in the mortar of the wall, and lugs on said anchor plates at right angles to one another to form stops for said anchor plates in the folded and extended position when inserted through said holding plates. I

9. In combination with a channel shaped metal frame having inwardly extending sides with the outer edges thereof free, a cross bar having its. ends formed to engage over said outer edges of the sides, so as to prevent relative spreading of the latter, and spaced means integral with the frame sides and extending out therefrom to engage and limit the upward and downward movement of the bar, said bar being slidable between said spaced means and the latter being formed to project into the mortar and to provide mortar receiving parts.

10. In combination with a channel frame having spaced side flanges converging toward their free side edges, a cross brace extending across the space between said side flanges, and spaced means on the cross brace to engage on opposite side faces of the respective side flanges to prevent relative spreading thereof, said means of the cross brace being formed so as to be movable along the lengths of said side flanges of the channel frame.

In testimony whereof I have affixed my signature in the presence of two witnesses.
