The

M m ,1?! mentsbf Whicih are a r me: ha e bee hrinkag bn w 'thebgil d 3 dadoes I3 are wholly concealed when installation is complete, and may be filled with waterproof glue or with calking material at the time of installation, to secure the side jambs and sills together and to prevent entrance of foreign matter or moisture.

The sill I4 having been located and secured in place, the next step is to locate the side jamb I, this being the jamb which carries the hinges I5 supporting the door 9. One end, preferably its upper end, is spaced "from the adjoining studding (see Fi 3) by a spacer II, which preferably extends across the entire width of the jamb. With the jamb I plumb, at least in a direction perpendicular to the general plane of the door frame, its upper end is secured in this position by screwing home the screw II] which passes through the jamb, and which may pass through or near the spacer I I into the studding. Its lower end is then plumbed both ways, and is secured in this position by screws 6 passing through the jamb and into the studding. Preferably resilient means, illustrated as the coil springs I2, are employed between the back faces of the jamb and the studding surrounding the screws 6, these springs serving to space the jamb away from the studding, while yet permitting the screws 6 to draw the lamb towards the studding. These springs will also force the jamb away from the studding, upon slacking off the screws.

With the jamb I thus located, and with a leaf of the hinge I5, or at least the seat therefor, previously fitted at the factory, the door 9 will swing at the proper clearance above the sill I4, and at the proper clearance beneath the head jamb 3, which at this end rests upon the upper end of the jamb I, and is held against separation therefrom, such as would leave a gap.

The next step is the location and securement of the jamb 2, opposite the jamb I which has now been secured in place. The jamb 2 is adjustable in its spacing relative to the jamb I at both ends. It is adjustable at its lower end by reason of the adjustment accorded by the sill being cut short of the bottom of the channel I3. It is adjustable at its upper end by reason of the fact that the head jamb 3 is connected to the jamb I by means which permit some limited adjustment lengthwise of the head jamb 3, but which prevents any separation of the jambs I and 3. For example, screws 4 provided with washers 5 pass through holes in the head jamb 3, and into the end of the side jamb I. These holes are either slotted longitudinally of the head jamb, corresponding to the holes 20 as seen at the left in Figure 1, or are oversize holes permitting limited but sufficient adjustment rele ative to the smaller shank of the screws 4. The screws 4 are sufficiently tight to hold side jamb I and head jamb 3 in close frictional contact against separation, but are loose enough to permit the head jamb to slip across the end of the side jamb I when the screws 6 are tightened.

By such means the spacing between the side jambs I and 2 is adjusted, with just sufficient side clearance for thedoor, and the side jamb 2 is plumbed. It, too, is secured to its studding by screws 6 backed by the springs I2.

During the location of the side jamb 2, or thereafter, the head jamb 3 is leveled, and it will be observed that whereas its right end, as seen in Fig. 1., rests upon the abutted upper end of the side jamb I, its left end abuts the side face of the side jamb 2, and the two are connected in this relationship by' screws I having washers 8, the screw shanks passing through slots or enlarged curement of the casing elements I8. However, if

desired, securing means such as screws 6 and springs l2 may be employed to secure also the 7 head jamb.

The nailing of the casings I8 to the frame elements and to the studding securely and rigidly holds the frame in its proper position. If the casing I8 is nailed only to the studding, later adjustment of thefframe is facilitated, and the screws 6 and springs I2 'or 23 will adequately secure the frame.' Instead of using casings, the surface finish of the wall, such as lath and plaster,

' can be extended to lap onto the edges of the door jambs and be fastened thereto; the joint canbe concealed by a suitable moulding.

The frame having been thus installed the door 9 is hung, and if, as preferred, the hinges I5, the latch elements I6, and the-striker-plate I'Ihave been fitted at the shop or factory, the several parts will match properly and the door is hung and ready for use in-a minimum of time.

Since this is an exterior door [a threshold I9 would normally be installed, after installation of the frame'as described above, and its thickness would be taken into account in initially fitting the door at the factory. Also door stops 2| would be employed, and these may be either formed as part of the jambs or installed after installation of the jambs." If formed as part of the jambs the matching jambs will be rabbeted, as indicated at the top of the side jambI, and at the left end of the head jamb 3, to receive the corresponding door stops 2I, see Figure 2. When such door stops are thus received in rabbets they will not prevent the desired relativeadjustment'of the jambs at the corners, within the general plane of the frame as a whole; but will prevent both.

separation of the jambs at the joint, and adjustment of the jambs out of the common plane of the frame. the stops separately later, mitering their ends, if desired, and securing them in'place to cover the heads of the screws 6 and I0.

The form shown in Figure 2 is in substance the same as is shown in Figure 1, except that at the joint illustrated, that between the head jamb 3 and side jamb 2, while the endo'fthe head jamb still abuts the side face of the side jamb 2, the head jamb 3 is 'provided'with an extension 32 which overlies the end of the side jamb 2, and which is provided'with a hole intowhich is snugly fitted a dowel pin 3Iprojecting upwardly above and in prolongation of the end of the side jamb 2. Such a dowel pin (or pins) prevents relative displacement of the jambs out of the general plane of the frame as a whole, or in a direction lengthwiseo'f the head jamb 3 in this instance, but permits vertical adjustment of this end of the head jamb relative to'the side jamb 2 without the possibility of separation such as would leave a gap at the corner. A similar dowel'construction may be employed at the opposite end of the head jamb, although here horizontally disposed to permit relative'lateral adjustment between the side It is possible, of course; to install.
