ALFRED J. ELLIS, OF WOODCLIFF-ON-HUDSON, NEW JERSEY, AND CHARLES E. NELLIS, OF NEW YORK, N. Y., ASSIGNORS TO A. J. ELLIS, INC., A CORPORATION OF NEW JERSEY.

HOLLOW METAL DOOR-FRAME.

Specification of Letters Patent.

Patented July 2, 1912.

To all whom it may concern:

Be it known that we, ALFRED J. ELLIS and CHARLES E. NELLIS, citizens of the United States, residing, respectively, at Woodcliffon-Hudson, township of North Bergen, county of Hudson, State of New Jersey, and city of New York, borough of Brooklyn, State of New York, have invented certain new and useful Improvements in Hollow Metal Door-Frames, of which the following is a full, clear, and exact description.

This invention relates to hollow metal door frames, and has for its object the simplification of such structures providing a hollow metal door frame the parts of which may be readily assembled; our construction also obviatingthe necessity for extreme exactitude in laying out bolt or screw holes,

and the like. The frame is preferably composed solely of straight members, means being provided for. uniting such members to form a unitary structure. 1

A further object of our invention is to provide means integrally formed with certain of the said members whereby the latter may be firmly locked in position in brickwork or the like.

Other objects of our invention will be hereinafter set forth and more particularly pointed out in the appended claims.

Referring to the drawings which form a part hereof: Figure 1 shows an elevation of our improved door frame construction, the left hand side of the molding thereof being broken away to show some of the details of construction; a small section of the jamb and coiiperatin parts being further broken away to provid e a fragmentary section substantiall on the line II of Fig. 2. Fig. 2 is a ragmentary section of our frame, taken on the II-II of Fig. 1, the section being viewed as indicated by thearrows in Fig. 1. Fig; 3 is a perspective view of one end of one of the upright bucks. Fig. 4 is a fragmentary detail showing means for uniting the buck members. Fig. 5 is a perspective view of a left hand upper corner of the assembled jamb, viewed from above. Fig. 6 is a detail of one of the molding clips.

Like reference characters designate like parts throughout the several views.

Referring to the drawings, the vertical jamb sect-ions have been broadly designated 1, and the corresponding horizontal jamb section 2. These jamb sections are provided with suitable moldin 3 and are adapted to receive the door l, in the usual manner. .Each of the individual sections is virtually U- shaped, one of the legs of the U, as viewed in cross section, bein designated 5, and the other 6; the leg 5 being considerably longer than leg 6 for reasons hereinafter set forth. The exposed face of the jamb is rovided with a molding. Upon either sid of the molding 8 of each of the jamb sections are flat portions]? and 8, and such flat portions in the horizontal sections are adapted to slightly overlap corresponding parts of the vertical sections, or vice versa, as indicated in Fig. 5; the horizontal overlapping section there shown being slotted at 9 for the reception of projections or tongues 10 which extend upwardly from the corresponding portion of the adjacent section; such tongues being adapted to be bent over so that the parts may be firmly locked together. Additional tongues 11 may correspondingly project from the overlapping section, such tongues being bent downwardly and inwardly toward and into contact with the adjoining section, thereby still more firmly locking the parts together.

The buck for our assembled jamb sections is similarly formed of two vertical members and a horizontal upper member; such members being respectively designated 12 and 13. These members are adapted to interlock in the manner shown in Fig. 4;, the vertical members being slotted as at 14 for the reception of tongues 15, which extend outwardly from and in alinement with the web of the buck member 13. We prefer to bend such tongues over alternately in opposite directions in the manner shown in.'

Fig. 4, whereby the respective elements are very securely united together. The flanges of all parts are preferably cut at 45 as shown at 16 in Fig. 3. The vertical buck members '12 have a series of U-shaped cuts 17 therein and'the tongue 18 so formed is pressed outwardly substantially at right angles to the body of the member, as in Fig. 3. We prefer also to corrugate such 1 and by reason of this fact it becomes possible to insert the assembled jambstructure into positionwithin the wall inclosed buck, the flanges 6 of the jamb and flanges 21- of the buck being narrow enough to permit of such insertion. After the amb has been so positioned, it may be secured to the buck in any suitable manner, as by screwsor bolts 22,

which engage the wider flanges of the buck and the narrower flanges 6 of the jamb, 20 while corresponding screws or bolts 23 on the other side of the door secure the flanges 5 and 21 together. On the hinge side of the I door, U-shaped hinge irons or strips 24: are

secured at spacedintervals to the inner sides of the flanges of the jamb, a bolt 22 in such cases passing through one of the legs of such U-shaped strip, while the other end of said strips may be correspondingly fastened by means of a bolt'25. We preferto recess of slot the exposed face of the jamb for the reception of the fixed elements 26 of the hinges 27, and hence these members may be directly secured to the hinge strips by means of screws or bolts 28. The webs of the buck members are slotted adjacent the edges thereof .at spaced intervals as indicated at 29 in- Figs. 3 and 4, and substantially L-shaped clips 30 are provided for engagement. with these slots, theinner or at 31 so as to neatly engage the webs. The shorter and laterally projecting legs of these clips areslotted as shown in Fig. 1 for the reception of bolts 32. A buck having been built in position; either before or, afterthe jambis. placed therein, .the clips 30 are hooked into engagement with the respective slots, and the plaster 33 is applied therearound.- This plaster serves to temporarily hold the clips in position so that they pro- .ject outwardly from the face thereof, and the respective sections of molding 34 are then applied-to the face of the plaster and into engagement with the jamb flanges 5 and 6, the inwardly projecting flanges of the moldings 34 entering into and embeddingtheir edges in the plaster as at 35, the bolts 32being' screwed securely into place ,tolock the several partstogether. Bolts 32 are preferably provided with nuts 36; and the clips 30 are slotted at 37 in the manner indicated in Figs. 1 and 6, so that a certain amount of play is allowed in order that the respective molding sections may be neatly fitted together. The provision of slots 37 longer legs of such clips being hooked as in the clips and slots 29 substantially at right angles \to such slots in the webs of the buck'sections, allows for adjustment of the molding sections in all lateral directions and obviates the necessity for any great 'exacti-- tude in the positioning of bolt holes and the like.

It will thus be seen that our com frame construction may be most readily assembled,

preferably but one portion of the same, to wit, the buck, being built, into the brickwork at the time such brick-work erected, the remaining portions being adapted to be applied thereto after the wall has been faced with plaster.

What we claim, is a 1. In a hollow metal door frame, a sheet metal buck having flanges upon opposite sides thereof projecting from the body of the buck out into'the door space, flanges on one side of said door projecting more than the flanges on the other side,'a jamb insertible into said buck, and means for securing said jamb in: place, said jamb being adapted for direct engagement with the sald flanges.

2.
