SEAL-TIGHT ROOFING cLEAT.

Application filedJuly 24,1922. i Serial No. 576,918...

To all whom it may concern:

lie it known that I, WILLIAM .C. Jo nsoN, a citizen of the United States, residing at Minneapolis,in thev county of Hennepin and overlapping sheets of roofing material and;

particularly to a cleat adapted to be used with such a roof. Roofs are now com.- monly covered-with sheets of mater alcomprising various waterproof and weather re-. sisting substances such as asphaltum, and

the like. Such sheets are vusuallyjplaced on the roof with the edges in overlapping relation, and such overlapping edges fastened with nails or staples. Under action by the weather, such roofing expands and contracts more or less and the fastening means or nails are lifted somewhat. The moisture often gets under the nail heads and finds its way to the interior of the roof through the nail holes, thus damaging the roof and producing leaks.

It is an object of this invention to provide a cleat covering the edge of the overlapped layer and also adapted to cover the nails or fastening means. i It is more specifically an object of the invention to provide such a cleat comprising a strip of sheet material bent at one edge to contact the edge of the overlapped roofing sheet and having its other edge bent upon itself to cover the fastening means extending through the cleat.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings, in which like reference characters refer to the same parts throughout the different views, and in which Fig. 1 is a plan view of a portion of'the roof showing the cleat applied thereto; and

tially on the line 2-2 of Fig. 1, as indicated by the arrows.

Referring to the drawings, a portion of a roof is shown comprising a base portion formed of boards lplaced adjacent each other and which will be supported on the enable others skilled in the art to which ;it-

roof studding. These boards may,

sired, be provided with interlocking tonguesandgrooves, as shown in F 1g. 2. On this I base are laid the sheets2ofthe roofing ma terial, the lower edges of said sheetsoverlapping the upper edges thereof throughout i the extent'of the roof. ;The; sheets .arefas tened to the roof base by fastening means illustrated as nails 3 which pass through the overlapped portions of thesheets. In accordance .with the presentinvention, acleat designated generally as 4 is provided. This. I

cleat is formed witha strip,orfsheet ofma terial preferably sheet metal, such as :gal-

vanizediron, adapted to extend along and adjacent the edge of the overlapping sheet 2. The nails 3 are driven through the cleat,

as shown in thedrawings said nails. being I spaced at suitable distances to properly-hold the .sheets. The nails may; be driven through. holes provided in...the cleat, or as the cleat is of comparatively thin'material, the nails may puncture the same. when driven. The cleat has one edge 5 thereof illustrated'as the lower edge bent to extend substantially at right angles to the main portion of the cleat which receives the fastening means, and this edge is adapted to overhang and contact with the edge of the overlapping sheet. In making this bend a small bead 6 is formed extending longitudi-- nally of the cleat. The other edge 7 of the cleat is first bent upwardly, as shown in the upper part of Fig. 2, and after the nails 3 are driven in place, the edge is bent downwardly on the body portion 45 of the cleat in substantially parallel relation thereto and has its lower edge positioned substantially in contact with said body portion, as shown in the lower part of Fig. 2. The strips 4 will be made in appropriate lengths and abut, end to end, as shown in Fig. 1. In practice, it has been foundthat the length of about twenty four inches is a convenient length for said cleats.

'While the cleat has been illustrated as applied tothe sheet 2 extending transversely of the roof 1 the plate can be used on roofing in which the sheets extend vertically or up and down on the roof. In some cases it is From the above description it is seen that more convenient to have the length of the sheet and forms a tight seal therewith. The c applicant has provided a simple and eflicienjt roof cleat. By the use of this 'cleat the edge of the roofing sheet is protected and the fastening means are entirely covered. The

cleat presses tightly against the roofing damaging effect of the weather on the attaching portions of the sheet are thus effectively overcome. The cleat has been found to be very efficient and effective in actual practice.

It will, ofcourse, be understoodthat various changes may be made in the form, details andfiproportions of the device without departing from the scope of applicants -in vention, which, generally stated, consists in the matter shown and'described and set forth in the appended claims.

l/Vhat is claimed is:

1;. The combination with overlapped sheets of roofing material, ofa cleat extending along and adjacent the edge of the overlapping sheet and having one edge thereofofa strip of sheet'material and extending along adjacent the edge of the overlapping roofing sheet, said cleat receiving the fastening means therethrough and having one edge bent over parallel to the main portion thereof to cover such fastening means.

3. The combination with overlapped sheets of roofingmaterial', of a cleat having its edge bent to overhang and contact with the edge of the overlapping sheet and having a raised head at said bend, said cleat having fastening means passing thereth-rough and having its other edge bent over on its main portion to cover saidnails.

4. A cleat for sheet roofing comprising a strip of sheet metal bent closely adjacent having its other edge bent over on itself to forma cover for fastening means passing through said cleat.

5. A cleat for sheet roofing comprising a strip of sheet metal'bent closely adjacentone'edge at substantially a right angle and WILLIAM C. JOHNSON.
