To all who mitt may 'a mem; I I

Be it known that I, CHARLEY BURNETT, a

Washington Court House, in the' county of Fayette and State of I'Ohio,'-J have"invented certain new and useful Improvements, in

I his invention relates to building. construction and is designed particularly as an improved roof construction, [although the invention is not necessarily limited thereto,

inasmuch as the principles and'structures involved may be applied with equalfacility to sidewall and similarconstructions. I

The main object of my invention resides in a construction designed to be 'i veatherproof and water-proof, construc-' tion, all joints are effectively closed to the admission of moisture and likewise all joints are so arranged that warping or shrinking in any manner.

will not distort or destroy the construction I This arrangement is also designed with a view of cheapness, the same being far cheaper to install when itseifectiveness is considered than structures heresectional view taken on the plane indicated by the line 2-2 of Figure 1, and

Figure '3 is an. enlarged detail view disclosing particularly the construction and operative position ofthe burred washer element. I 1 I In these figures, I have illustrated'my 1nvention in connection with a roof, although it is to be understood that the invention is not limited thereto, as it may be applied with equal facility to side wallor other construction.

In these views, the rafters are designated by the reference numeral land a the ridge pieceby the reference numerallk.

Between the rafters 1, I place a plurality of cross pieces 2 offset slightly from each other, as shown, so that the nails 3 may be driven through the rafters and into the ends of each of the cross pieces'2.

- 'After this, the grooves are covered-by means of metallic V-shaped strips 8 which are.

shaped to snugly fit the inclined bottoms 7. These metallic strips are in turn secured in position bymeans of nails 9 preferably having lead washers 1O interposed between their heads and the metallic strips. The metallic strips are preferably punched for the 'reception of these nails prior to their application to the roof, and these punchings are formed it from the inside ofthe stripsloutwardly, so as to leave upwardly projectin burred portions 11 in connection with w ich the lead washers must engage themselves when the attaching nails are driven home. These burred portions embed-themselves in the lead washers to make the joints weather tight and water tight and in additiomthese lead washers prevent direct contact of steel on steel and thus rusting is eliminated. The vnails 9, as shown, are driven into the rafters or cross pieces through the meetingedges of I the boards and because of the V-shaped nature of the metallic strips, any shrinkage laterally of these boards will only tend to tighten the joint between the metallic strips and the inclined bottoms-of the grooves. In this manner, it must be apparent that a very effective joint isproduced. Injoining two sections longitudinally, as is shown at 12,

I arrange the'joints together directly over on'eof the cross'pieces 2'and space the boards slightly from each other. Into the space thus formed, I place asuitable waterproofing' compound such as a combination asphaltum 1 '110 I and asbestos compound. 'These mixtures may be purchased in the open. market and are usually ofa semi-plastic form and when;

a. groove is thus filled with it, a very effective water tight and weather tight joint 13 produced. If desired, the entire roof may be painted with similar weather proofing compound. i. a

From the foregoing description, it will be apparent that I have provided a building construction in which all joints are efectively closed and which-at the same time is comparatively cheap to produce. The

jointsare so fo rmed; that longitudinal shrinka'ge'or distortion of the boards is perf'mitted, becausepreferably there is no perman'ent connection between the metal strips 8 and th'e 'groovededges of the boards to prevent such small relative movement as may occur :during the seasoning of the "boards. Any slight lateral movement or dis I tortion which may also occur during the seasoning action is permitted for the same reason, but this only increases the tightness metal strips 8 andthe offit between the boards themselves.

What I claim, is: In abuildingstructure, in combination, a backing, a pair of longitudinally extending rough forming members arranged side by side upon said backing so that theirmeeting v Witnesses lationship with said faces, consisting of a plurality of headed securing elements adapted to be embedded in said backing and formed to pass through openings provided in the ridge portion of said strip, said openings being punched out to define projecting bu'rred elements, and a plurality of i relatively soft metal washers locatedbetween the heads'of said securing elements and strip, said washers being formed to reopenings when the securing elements occupy their holding positions. V i In testimony whereof I afiixmy signature in presence of two witnesses;
