l The lpresemt invention relates tothe trim used in buildings, such as door and :window casings. In a more particular `aspect the inventionrelates 4to'metai trim for doors andwindows.

The conventional type `metal trim isot onepece construction. `Itis made at the factory and so 4shipped 'to the Job. `Convention al metal trim has, therefore, 'to be placed in the window and door openings before the walls are lplastered and painted. It has to 'be erected, While heavy work is stili being done on the building. It .has to stand in place while wheelbarrows ,are being rolled back and forth and whue scaffolding and other erection equipment is being Vmoved to and fro. It is very liable. therefore. to be marred or ented- Moreover, 2when it comes time to plaster the walls, the plasterer has to 'plaster-up "tothe trim, which naturally handicaps him. He is not able to make free-swinging strokes; and as a result has difdcultyinproducing a plane surface. Furafter plastering and vpainting aregnished. This prevents the trim from 'being damaged during erection of the building, materially reduces the cost of plastering and painting on 4-a job where metal trim is used, and simplies the work. It eliminates entirely the necessity for cleaning the trim after plastering and painting of the adjacent walls are completed.

Another object of the invention is to Kprovide metal trim which can be shipped in knockdown form and assembled at the vei-ectio'n site by rela'- tively unskilled labor.

7 Claims. (Cl. 18S- 416) lli A further object of the invention is to provide I metal trim which `can 'be removed Aand salvaged .one hundred per cent, without in any way fvide metal trim lfor 'door openings which canlat anytime easily be taken down and `reversecl in the door opening to permit reversal of the direction of swing of the door.

A further .object of the invention is to provide a 'kneckdown type .og trimwhich is made oa minimum number ci parts and isfinexpensive.

A sun further object of the invenu'cmis :to

provide knockdown, easily assemblable trim in which connections between the parts will be `concealed `when the trim is in place and which willll'ook like conventional one-piece trim when erected.

Other objects of the invention will be apparent 'hereinafterfrom'the specification and `from the recital of the appended claims.

' Fig. 10 is a fragmentary elevation with parts broken away, somewhat like Fig. 4, but showing this modified form of the 'invention.

door `casing constructed according to the present invention is' rnade with two main sections and withs'trips kwhich cover the adjoining ends vci the main sections. 'The two main sections for "conveniencemay be called outside and inside lsec-- tions, respectively.' One section seats against one sideandthe other against the other side of the --partition vwall in which the 'door opening is provided and the two sections are vdrawn together to clamp the casing in the opening.

in Figs. 1 to 4 'inclusive the two main sections are denoted at20 and 2i, respectively. These sections are each U-shaped; and each comprises a nair of parallel side rails 22 and a connecting top rail "24. `The side and top'rails of each section are mitered at their adjoining ends and welded together so that leach section can be handled as one piece.

'The rails may obviouslybe `rolled or stamped to any desired shape in cross-section to suit the :style o; architecture selected.: In the embodiment shown, each 4rail `conzipifises anat side 25 from one 'end of which-projects outwardly `a terminal strip 26 and from the other end of which projects inwardly the side wall 21. From the side wall 21 is bent inwardly a flange 28. The flanges 28 of the top and side rails of the two sections are adapted to vabut against opposite faces 30 and 3| of the partition wall in which the casing is to be mounted. l

Each rail is reinforced at spaced points alon its length by reinforcing strips such as denoted at (Figs. 3, 4 and 5). These reinforcing strips comprise strap portions 36 and legs 31 and 38 which project in opposite directions from the strap portions 3B. Each leg 31 has an abutment strip 39 projecting at right angles from it in one direction; and. eachstrap portion 36 has a tongue 40 stamped out of it and bent to project at right angles to the leg 31 of the reinforcing strip in the opposite direction from abutment strip 39. Each tongue 49 has an elongated slot 4| formed therein.. K

, The legs 38 of the reinforcing strips are bent to conform to the shape of the side walls of the frame sections as shown clearly in Fig. 3, and are spot-welded to the insides of these side walls. The terminal portions 42 of the legs 38 are also preferably bent slightly inwardly and spotwelded to the insides of anges 28 of the frame sections. The abutment strips 39 are vspotwelded to the insides of the sides 25 of the frame sections. A very rigid structure is thereby provided. All spot-welding is done, of course, in the factory when the frame sections are being manufactured.

The U-shaped sections 20 and 2| are ordinarily painted at the factory and shipped in cartons to the iob. After thepartition walls have been plastered and painted and all the heavy work on the building is completed, the novel door or window framing of this invention can be placed. To do this the workman may drive nails 43 through the slots 4| in the tongues of the reinforcing strips 35 into the studding`45 (Fig. 3) to hold each frame section in place.

After the two frame sections 20 and 2| are so held, he will pull them together so that their (Fig. 5) in it. To pull the sections 20 and 2| together and clamp them to the partition, the workman drops a bolt 5n in the notches 44 of registering reinforcing strips 35 of the-sections 29 and 2|, puts butterfly nuts 5| on opposite ends of the bolt and rotates the bolt.A 'I'he butterfly nuts are held against rotation by engagement with the reinforcing strips. The bolts 5|) may have polygonal center portions for easy grip by a wrench. The slots 4| in the tongues 40 of the registering reinforcing strips permit adjustment of the frame sections while they are 'held to the partition by the nails 43. One man can, therefore, very easily assemble the fra-me in a door or window.

Ordinarily clamping bolts and butterfly nuts 5| need only be .used in the reinforcing strips attached to the side rails .of .the frame sections to pull the frame sections together. Thetop rail of each framesection is .welded to the side rails thereof so that when the sides of the frame sections are pulled together, the tops of the sections will be pulled together also. If desired, however, bolts 50 and butterfly nuts 5| may be used between the reinforcing strips 35 of top rails as well as of side rails. All the reinforcing strips are made alike for convenience in manufacture, and the reinforcing strips welded to the top rails of the two. sections of the frame will have notches 44 in them just like the reinforcing strips welded to the side rails of the two frame sections.

Obviousl/instead of double-ended bolts, bolts threaded at one end only may be employed to pull the frame sections together. Thus, each bolt may be headed at one end and threaded at the other;A thebolt may be dropped vin aligned notches .44 of registering reinforcing strips 35 with the head of the bolt seated against the outside of the leg 31 of one reinforcing strip and with a butterfly nut 5| threaded on the opposite end andseating against the outside of the registering reinforcing strip. By rotating the bolt, then, the two frame sections may be drawn together. Where a single endedV bolt is used, obviously, also, the bolt may be threaded directly into the leg 31 of one of the two registering reinforcing strips and this strip need not be notched forvv reception of the bolt. Other a1- ternatives will readily suggest themselves to those skilled in the art.

After the frame sections are in place, covering strips are placed over the adjacent ends of the sections to conceal the terminal strips26 thereof, bolts 50, studs 45, etc., and to give the completely assembled frame the appearance of a conventional one-piece casing. Separate covering strips are used for the sides and the top of the frame. The side covering strips are denoted at and the top covering strip at 56 (Figs. 2, 3, 4, '1 and 8).

The side and top covering strips are similar in construction. Each is U-shaped in cross-section and is adapted to be placed over the adjacent ends of the frame sections with its fiat part 51 out and its legs 58 extending inwardly and enclosingv the terminal strips 26 of the frame sec-v tions. The side and top covering strips differ from one another onlv in that the top covering' strip 56 has two parallel slots 59 cut into its iiat part 51 from both ends while each side strip 55 has two tongues 60 bent upwardly from its upper end and is unslotted at either end. The tongues 60 of the two side strips 55. respectively, are adapted toengage in the slots 59 at the opposite ends, respectively, of the top strip 56. Corresponding slots 59 at each end of the top strip may loe-made. as shown in Fig. '7, wide enough to' permit adiustment of the frame members with# out interference.

Spring steel C-clips are welded to the insides of the at portions 51 of both the side and top covering strips. These engage the opposed surfaces of terminal strips 26 of the frame sections to resiliently but securely hold the covering strips in place.

The top covering strip 55 is first put in place by shoving it over the terminal strips 26 of the top rails 24 of the frame sections 20 and 2|. The springs 65'will hold it in place. Then each side lcovering strip 55 may be put in place by irst inserting its tongues 60 into one pair of slots 59 of the top covering strip and then shov- .ing it inwardly to cause its spring clips 65 to engage opposedside surfaces of cooperating terminal -strips .26 of the-related side rails 22 vof the,- -frame sections 20 and 2|. Ijhe springs, 65. willhold the covering strips in assaut place, but, if desired, `each :side 'covering' "strip may, 'in addition, befastened'by a screw 61 itoan anchor plate (Figs. 2, 4 and 6) by threading the screw into one leg 'Il ofthe anchor plate.

The anchor plates may be fastened tothe floor by screws that pass through holes l2 lin theplates. The legs 'I3 of the anchor plates arefadapted to abut against the studding .65.

Where the trim of this invention is to be used as a door casing, one frame section, such as vsection 23, will have hinges 'secured to it on which the door VD (Fig. 3) may be hung. The

covering strips and 5t will vthen Vserve as A4a stop, corresponding legs 5,8 of the side and vtop covering strips seating against the terminal strips 2% of frame section 20 for this purpose. The covering strips are, of course, made suiciently wide to allow of any-required adjustment of the frame sections while accomplishing their purpose. l

in the modiiication of the invention `shown Figs. 9 and l0, two frame sections and cover strips are employed as in the flrst described embodiment of theinvention, but different means is used for drawing the two frame sections to- =f gether to clamp them to the partition wall. 'The frame sections and `8l shown in Figs. 9 and 10 are somewhat diferentin cross-sectional Ashape from the frame sections 20 and 2 I. This simply illustrates that the invention may be used vwith casings of a wide variety of rolled or stamped shapes and architectural styles.

.Each of the ' frame sections 80 and 3,! has a `flat side 86, from one end of which the terminal strip Bl projects outwardly and from the other y end of which the side wall 83 projects inwardly. The side wall is flared laterally as denoted vat 89 and from the flared portion there extends the odset portion 90 which is .parallel to the main portion of the side wall but oiset therefrom. A flange portion 9| extends at -right angles to offset portion 90 of vthe side wall and a terminal abutting strip 92 extends at rightv angles to the flange portion.

To the inside surfaces of the side walls 88 vof the side rails of the frame sections there are fastened at spaced intervals right angular shaped metal strips do `which constitute metal jamb hook eyes. One leg of each of these straps `is spotwelded, or otherwise secured to the side wall 88 of a frame section. The holes 95 in these hook eyes are adapted to receive the downwardly projecting legs 9S of U-shaped metal hook clamps tot, the legs of each clamp vengaging `in the holes ci registering 'hook eyes. legs SS of each hook clamp are inclined and diverge downwardly from one another, so that the hook clamp is driven downwardly in -a pair of hook eyes by a hammer, awedging effect will be obtained and the two frame sections will he pulled together to clamp `opposite sides of the partition wall which are denoted at |05 and it, respectively. The insides of the legs te may also be serrated as shown in Fig. l0 to improve the gripping action of these legs on .the hook eyes. l

ceall -'the terminal' strips 18j, hook clamps, etc., and .to give the casing a :finished appearance. `The covering .strips are heldin place by spring steel clips H0, *similar 'to the `clips 6E used in the dist-described embodiment of the invention kand spotfwelded to the insides of the` covering strips. These `clips engage .opposed surfaces of .terminal strips -81 and resiliently but securely Ahold the covering strips in position. The covering strips `85 serve as a stop when the casing is lused as a door frame.

With either embodiment of the invention it will be seen that the trim can be erected after mastering and painting has been done and without damage to either. l

' Furthermore, with either embodiment of the invention the trim can be removed at any time without damage to the trim or to the walls. The .screws at the bottoms of the side rails can be removed; and the screw driver can then be inserted under the edges oi each covering strip to pryit ci the frame sections. This is a simple task since 'the .covering strips are then only held by spring clips 65 or H0. After the covering strips are removed the bolts 50 can be loosened .and lifted out of the notches 4d of the reinforcing strips 35 and the nails 43 drawn in the case of the embodiment shown in Figs. l to 8 inclusive, or the nails |01 can be drawn and the hook clamps l0!) driven up to release the frame sections in the case of the `mooliication shown in Figs. 9 and lo. In either instance, it is a matter lof a few minutes work to remove the trim; and the trim can be salvaged .It it is desired to change the direction of swing ci a door this can be done readily by removing the frame sections from the door opening, ,reversing them, and reclamping them in the opening. The trim of the present invention,

. there, vis flexible iii-adaptation, easy to erect or dismantle, vand permits of considerable saving in time and cost of erection.
