9 Claims. (Cl. 20-12) This invention relates to prefabricated door and door frame units and more particularly to such units of the split-jamb type.

The hanging of doors and the trimming out of the frames has always been an expensive and timeconsuming task. Even though prefabricated door and frame units are known, considerable trouble has been encountered in setting up the units, getting them properly plumbed in the rough frame studding and aligning the separate sections of the jamb before permanently `securing them in place. Many on-the-job improvisations have been resorted to to `hold the various parts in position while they were being aligned and permanently fastened. Many times the jambs were warped during installation so that the frame was not plumb and an imperfectly operating door resulted.

The object of the present invention is to provide a prefabricated door and frame incorporating means for initially plumbing the rst section of the two-part frame and holding it in adjusted position while the remaining portion is installed.

Another object of the invention is to provide in such structure means for accurately aligning the two sections and holding them properly aligned while they are being permanently fixed to the studding.

A further object of the invention is to provide aligning means for the sections which alsoforms a solid base to hold the jambsagainst warping as they are being secured in position. i

A still further object is the provision of means for initially plumbing the rst section to `be installed, which means also serves as aligning means for the several sections. i

Other objects of the invention will become apparent from the following description of practicalembodiments thereof when taken in conjunction with the drawings which accompany, and form a part of, this specification. I i

Figure 5 is a fragmentary elevational view showing a portion of one of the jambsand illustrating a slightly modified form of the invention; and, i

Figure 6 is a partial horizontal section through the structure shown in Figure 5, and is taken substantially on the line 6 5 of Figure 5.`

In general, the present invention comprises Ia pre,- fabricated door and frame assembly of the two-part jamb line type having means for initially holding the frame in place in the rough studding framing the door opening, which means also serves to align the sections of the jarnbs and form a solid base to hold the jamb sections in position while nailing or screwing the assembly in place. i

Referring to the drawings in detail, there is shown the customary rough framing in a partition wall 1 outlining the door opening and to receive the door and door frame. The framing consists of the usual vertical studding members 2 which are spaced apart a distance greater than the desired width of the linished door open ing, and the horizontal member 3 bridging the tops of the vertical members 2. The prefabricated door frame of the present invention is split longitudinally into what will be referred toas a front section 4 and a back section 5. The two sectionsare put in place from opposite sides of the door opening to form the finished frame. The front section 4 of the frame consists of the two jambs 6 and 7 and the lintel 8. The jambs 6 and 7 are permanently fixed to the lintel S, and held in spaced parallel relation by means of the lintel. The usual facing panels 9, 1l) and 11 are nailed to the jambs 6 and 7 and the lintel 3. These panels may be trimmed in any desired manner with moulding strips. When the frame is in place in the door opening the panels cover the rough studding. `A door 12 is mounted in the front section of the frame by means of hinges l?, fixed to the jamb 6. The door has the usual provision for a latch and locking means to cooperate with the jamb 7.

The inner edge of each jamb is provided with arcuate recesses lil spaced apart along its length. Three such recesses are shown on each jamb, but it will be understood that in actual practice more will be provided as required. They probably will be located on eighteen inch centers. The lintel S has its rear edge similarly recessed, as shown at 15. Recesses 14 form the mounting means for small jacks 16. lacks i6 have a cylindrical hub portion 17 which is of a length substan tially equal to the thickness of the wood of the jambs. A flange 1d, of considerably larger diameter than the hub, encircles the jack approximately at the center of the hub, and when the flange is seated in a recess i4, the ends of the hub `are substantially flush with the side surfaces of the jamb. Hub 1;'7 is centrally bored and screw-threaded to receive a screw 19 which carries a bearing head Ztl. The opposite end of the screw 19 has a kerf so that a screw driver may be used to move the bearing head toward and away from the hub portion of the jack. After the ilange of the jack has been inserted in one of the recesses 14, a small nail 2l is driven through the jamb and passes through an opening Z2 in the ilange liti of the jack to securely hold the jack in position upon the jamb.

No jacks are used along the lintel Si, but disks Z3, similar to the flanges itl of the jacks, are seated in the recesses l5 and held in place by nails Disks 23 are imbedded in the lintels slightly less than bali their diameters, as are the anges i3 in the jambs, so that theyproject well beyond the rear edges of the lintel.

The back section of the frame is composed of the spaced jambs 25 and 26 and the lintel Z7. Face panels 28, 29 and Si) are attached to the jambs 2:5', 26 and lintel 27 respectively. The jambs have arcuate recesses 31, similar to recesses 14 and similarly spaced along the rear edges of the jambs. Lintel 27 has the recesses 32. After the front section of the frame has been put in place, as will be described, the back section is slipped into the rough opening and the protruding portions of the flanges 18 of the jacks and the disks 23 iit into the respective recesses 31 and 32 of the back section. This will 'bring the inner `sur-faces of the jambs and lintels of the twg trams restless into absente alignment- Any gap between the edges ofrthe two frame sections will be covered by the installation of a conventional bumper strip 33.

In installino the prefabricated `frame and door unit just described, thefront section.' of the frame with the door in place is slipped into the roughed-in opening until the face panels 9, and 11 lie flat against the plaster or other tinishing substance on the wall. The jacks 16 will v thenbe manipulated ,by means of a screw driver to bring the bearing heads 20 snugly up against the vertical studding members 2. These can be adjusted to set the frame and door plumb in the opening. The jacks are tightened sudiciently against the studding to hold the frame snugly Y Iin place.` The sill 10 may be secured in place bridging the bottoms of the jambs of the front section to hold the jambs in proper spaced relation during shipping and VVto prevent the vbottom of the jambs from being forced toward one another as the jacks are tightened against the st udding. If desired, the sill may be omitted and any suitable brace (not shown) used in its place during shipping and installation. When the front section is irmiy in place, the other section Vof the frame is slipped into the opening from the rother side of the wallV or partition. The recesses 31 and 32 are slipped onto the projecting portions of the anges 18 and disks23, and

the back section pushed inwardly until the facing panels 2S, 2* and 3d lie flush against the wall. The distance separating the edges of .the sections when in place will vary according to the thickness of the wall. The jambs of the two sections can be nailed or otherwise secured Vtotl'ie studding to permanently hold the frame in place. The .nails will be driven through the jambs close to the jacks i6 which willhold the jambs perfectly true during the nailing. The jacks, bearing against the studding, form rigid bases yto prevent movement of the jambs as the nails are driven in. After the two frame sections are securely fastened, the bumper strip 33 is nailed in place covering the gap between the edges or the jamb and lintel sections. This completes the installation.

it will be understood that the two frame sections will be prefabricated and the door hung in the front section at a mill and the unit shipped to the job Where itis to be installed. The unit will be suitably braced and packed for shipmentvto prevent damage. y In Figures 5 and 6 a slightly modified form of the invention is shown. Here, the jambs 34 of the front section are grooved, as at 35, alongthe entire length of their rear edges, and receive a tongue 36. The tongue is as long as the groove and may be fixed in the groove by brads 37, or by other means. The protruding-portion of the tongue is provided with a plurality of openings 38 which are spaced along the tongue close to the edge of Vthe jamb 34 to receive the hubs 39 of jacks 40. In this form, the jacks have'flanges 41 at one end of the hub which are smaller than the anges 18 of the form previously described. The flange fits against one side of the tongue 36 and may be riveted or otherwise secured to the tongue, as at 42. The hub is bored and tapped to receive the screw 43 having a bearing head 44. The inner edge of the rear jamb section 45 is also provided with a longitudinal groove 46 so that when the two sections of the frame are iitted together the tongue 36 will tit within the groove 46 to align the sections. It will be understood that the lintel sections may be provided with similar grooves and a tongue (not shown) for aligning these portions. f

The modified structure is assembled in the same manner as that previously described. The front section is put in the opening and plumbed and locked in position by means of the` jacks 40. The rear section is then put in place and the assembly permanently xed, in place.

While practical embodiments of the invention have been described labo ve,.itwill be ,understood that the prel cise structure disclose dis merely by way of example,

and the invention may take other forms within the scope of the appended claims. Y
