FELIX E. LIETZ, OF BUFFALO, NEW YORK.

ASIHINGrLE LOCK.

Application led December 18, 1925. Serial No. 76,166.

To all whom t may concern:

Be it known that I, FELIX E. LIETZ, a citi'- zen of the United States, residing in Buffalo, in the county of Erie and State of New York,'have invented new and useful Improvements in Shingle Locks, of which the following is a specification.

This invention relates to the type of vshingles which are substantially square and laid diagonally on the roof and provided with turned-under corners to thicken theii horizontal lower edges and give them a strong and heavy appearance. Usually, they are composed of composition roofing such as felt saturated with asphalt and faced with crushed slate or similar mineral, to render them 'flexible Some of theobjects of my invention are to simplify the means for locking the lower corner of the shingle in place; to provide a strong concealed lock yof this kind which will effectually withstand the lifting and loosening effect of wind andrainstorms and to materially reduce the cost ofthe same. A further object is to so construct the shingle and its locking device that the .shingle can be easily adjusted up or down on the roof to aline it with adjacent shingles in the same row, and so that it is free to eX- pand and contract in response to changes of temperature, thus preventing buckling of the shingle and allowing it t0 lie smooth under all weather conditions.

In the accompanying drawings:

Figure 1 is a fragmentary top plan view fof a roof embodying the invention. Figure 2 is an enlarged fragmentary top plan view, partly in section, on line 2 2, Fig. 3. Figure 3 is a vertical longitudinal section of the roof on line 3-3, Fig. 1. Figure 4 is a perspective view of one of the'fasteners.

Similar characters of reference indicate corresponding parts throughout the several with the head or cross-bar 15 of a substan` tially T-shaped fastener, by preference, of, galvanized iron, the stem 16 of which passes through the slot and is driven through the underlying starting strip or shingle or both, into the roof board. The head or cross-bar of the fastener is of suflicient length to overlapthe folded-under corner for some distance on either side of the slot to form a strong lock which rigidly holds the lower corner of the shingle down in place against the bending or lifting action of storms.

In laying and securing a shingle of this improved construction, assuming a course of such shingles to have been previously laid, one of the fasteners is driven into the roofboards with its shank located below and in line with the meeting side corners of two.

previously-laid shingles and with its crosshead` arranged horizontally, as shown in Fig. 1. A. shingle with its slotted corner folded is then interlocked with the vcross-head of the T-fastener by bringing the slot in line therewith, as shown by dot' and dash lines in Fig. 2; then giving the shingle an upward quarter turn or swing to the position shown by dotted lines in said figure, bringing the slot at right angles to the cross-head, and finall nailing the side corners of the shing es to the roof-boards. To facilitate the turning or swinging movement of the shingle, the end portions of the T-fastener are beveled on their undersides, as shown at 17,l in Fig. 4. A

By this construction, the shingle is securely, interlocked with the fastener and the latter is covered and concealed by the body of the shingle, producing a sightly roof exhibiting thick and heavy-appearing edges at the lower corners of the shingles.

Owing to the vertical arrangement -`of the locking-slots, the shingles, after being interlocked withv the fasteners and before being nailed at the side corners, can be easily shifted up or down to accurately aline their folded lower edges and side corners with REISSUED those of adjacent shingles in the same course.

As is well-known to those conversant with this art, changing weather conditions cause the flexible composition material, from which such shingles are cut, to expand or for such Weather changes, allowing them to remain flat under all conditions and preserving the attractiveness of the roof.

The lock, While affording a strong and reliable fastening, is exceedingly simple 1n construction in that 1t lnvolves no separate or additionalparts and it can therefore be manufactured at a comparatively loW cost. The lock is of such a character that When the shingle is once properly engaged with the fastener, it is impossible for it to become loose or unlocked from it.

While the construction hereinbefore devscribed has been found very useful and desirable, I do'not Wish to be limited to it as it may be modified Within the scope of the appended claim.

I claim as my invention:

The combination of a4 roof, a fastener of substantially T-form engaging the roof, and a flexible shingle having a turned-under lower corner provided with a slot interlocking with said fastener, the body of the shingle overlying and concealing 'the fastener and the shingle slot being disposed at an angle to the cross-head of the fas-- tener, requiring a partial turn ofthe shingle relative to the fastener to interlock its folded corner therewith.`

FELIX E. LIETZ.
