Generally it will be wide enough to cover most of the top of the building wall.

Instead of being L-shaped, as shown, the wallplate may, if desired, be T-shaped, i. e., part of its vertical portion may extend below the horizontal portion. All that is necessary is that it possess both a vertical and a horizontal portion, and that at least part of the vertical portion extend above the horizontal portion, thus providing a right-angled seat for the ends of the roof rafters.

The horizontal portion of the wall-plate is provided with apertures or slots 2 that may be approximately one-half the width of that portion and are of considerable length. The length of these apertures is limited by the required rigidity of the structure. Generally speaking, it is desirable to make them as long as is compatible with that requirement. These apertures serve a variety of purposes. In the first place they provide openings large enough so that the plate may be readily set down over the anchor bolts 3 that have been built into the top of the wall as usual by the mason, without any exact measuring or drilling, thus saving considerable labor. They also provide openings through which the vertical portions of the adjustable c eats 4 extend at desired intervals. Finally they serve to lighten the structure and conserve material.

7 It will be noted that at the longer edges of the apertures or slots the Wall-plate is reduced in thickness, providing recesses I9 running the full lengths of the apertures to accommodate the ends of the horizontal portions of the cleats 4. The vertical portion of the wall-plate is provided with means for attaching the gutter 5 thereto. These means may consist of threaded holes 6 at suitable. intervals for the insertion of tap screws 1, as shown in Fig. 1. Preferably these holes are located high enough to be above the water level of the gutter.

The gutter 5 may be of any convenient shape and is suitably furnished in lengths equal to those of the wall-plate. When first installed, the gutter and wall-plate may come assembled and be furnished as aunit. The gutter is provided with corresponding holes for insertion of the cap screws I. Some of the gutter sections may be provided with a hole 8 for insertion of a drain pipe or leader 9. The gutter. is also provided with end or return pieces to give the proper archi tectural effect on the end walls of the'building without the necessity of finished carpentry work to accomplish this result. As shown in Fig. 1, the vertical portion of the gutter, which is attached to the vertical portion of the wall-plate, preferably extends somewhat below the horizontal portion of the plate, so that the gutter serves to seal the oint between the horizontal portion of the wall-plate and the top of the building wall It) against the entrance of moisture.

The adjustable cleats 4 which are shown in detail in Figs. 3, 4 and 5, are right-angled, metal brackets in which the horizontal portion is of greater length than the parallel dimension of the vertical portion, thus affording ends which are to be held under the wall-plate in the recesses along the apertures therein. The said parallel dimension of the vertical portion and the width of the horizontal portion must be less than the width of the apertures in the wall-plate to permit insertion of the cleats through the apertures during installation. The vertical portion of the cleats is provided with a suitable number of holes or a slot I I through which nails l2 may be driven the wall-plate.

into the roof rafters l3 and ceiling joists M, as shown, for example, in Fig. 5. The form of cleat shown in Fig. 4 may be modified by locating the ends of the wire of which the cleat is made at the top of the vertical portion, bending both ends of the wire in a direction parallel to and away from the horizontal portion, and pointing the said ends. These pointed ends can then substitute for the nails indicated in Fig. 4.

The means for fastening the wall-plate to the top of the building wall include the anchoring bolts 3 and anchoring saddles i5, one of which is shown in detail in Fig. 6. The anchoring saddles are of greater length than the width of the apertures in the wall-plate. so that they extend over both sides of the apertures and serve to securely hold down the wall-plate, when the nut I6 is tightened on the anchoring bolt 3. If desired, a washer I1 is provided between the anchoring saddle and the nut.

The method of installing my new wall-plate and of attaching the various building elements thereto is as follows:

The building wall l6, which may be of brick asshown in Fig. 1 or of stone, concrete or any other building material, is brought up to its proper height with built-in anchor bolts 3 at suitable intervals, for example, every 4 or 5 feet. In the case of brick or stone, a thin cement bed is is then trowelled on top of the wall to provide a level bearing surface. Then the wall-plate I is laid on top of the wall with the anchor bolts extending through the apertures 2 in its horizontal portion. The vertical portion of the wallplate is usually, but not necessarily, located flush with the exterior of the building wall, as shown in Fig. 1. The anchoring saddles l5 are then placed over the anchoring bolts 3, as are the washers i1 and the nuts l6. Before tightening the nuts, the desired number of cleats 4 are inserted'through the apertures in the horizontal portion of the wall-plate. This is possible, because the width of the horizontal portion of each cleat is less than the width of the apertures in After insertion each cleat is turned at right angles to assume the position shown in Fig. 1, whereby the ends of its horizontal portion are accommodated by the recesses i9 in the under-surface of the wall-plate on both sides of the apertures. It is also possible, where the required number of cleats is known beforehand, to insert the vertical portions of the cleats through the bottom of the wall-plate before laying down the latter, in which case the horizontal portions of the cleats can be wider than the aperadjoining each of the roof rafters and joists.

While it is customary to provide such rafters and joists at regular intervals, it is sometimes necessary to do so at irregular intervals, in case a chimney, a dormer window, or the like interferes. The length of the apertures in the wallplate makes it possible to adjust the positions of the cleats to take care of any such irregularities.

Once the cleats have been seat up in the desired positions, the nuts on the anchoring bolts ma be tightened to hold them there. Then the ceiling joists and roof rafters are nailed to the vertical portions of the cleats, as shown in Figs. 1, 2 and.5 of the drawings. The ends of the roof rafters are firmly seated within the right angle formed by the wall-plate, and any lateral force exerted by the rafters is taken up by the vertical portion of the wall-plate. The cleats eliminate the necessity of toe-nailing the 'roof rafters and ceiling joists, and the entire assembl provides a very secure joint between the roof, ceiling and building wall.

For the original installation it is preferable that the gutter and the wall-plate be furnished already assembled. Conceivably they might be furnished in a single piece, but this would not be practical, because the wall-plate becomes an integral part of the building and could not be removed, in case the gutter must be replaced due to corrosion or some other injury. It is, therefore, desirable that the gutter be readily removable for replacement, as in the structure shown in Figs. 1 and 2. The joints between the gutter sections may be sealed with a caulking compound as shown at 2| in Fig. 2.

My new wall-plate provides a very convenient means for firmly attaching the gutter. The gutter is securely held so that it can never sag, and yet it can be readily replaced. It is possible to thus provide not only a very elficient gutter construction, but also one that is quite pleasing in appearance.

It is obvious that many variations from the specific construction herein illustrated and described may be made without departing from the scope of my invention. Such variations and modifications will readil occur to those skilled in the art. I, therefore, do not limit myself to the particular forms herein described, but intend to cover all such variations and modifications as are embraced within my claims.

I claim:
