MAX RACHLIN, OF BROOKLYN, NEW YORK, ASSIGNOR F ONE-HALF TO SAMUEL M. GOLD, 0F NEW YORK, N. 'Y.

ROO'F COVERING.

Application led February 8, 1922. Serial No. 534,933.

To all whom it may concer/n.'

Be it known that I, MAX RACHLIN, a citizen of Russia, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new 'and useful Improvements in Roof Coverings, of which the following is a specification.

The present invention relates to a roof llcovering, and more particularly to that type wherein sheets of roofing material are laid and fastened to a supporting surface in the ordinary manner of laying shingles.

In this type of roof covering, sheets of a size exceeding considerably that of ordinary shingles are fastened to a supporting surface on the roof, the sheets of each succeeding row overlapping the underlying row. Each of the sheets is of a width,

corresponding to the length of an ordinary shingle and its length being a multiple of the width of a shingle. The sheets are fastened to the supporting surface by nails, extending in a line that coincides practically with the longitudinal center line of the sheet, care being taken that the nails are not driven through the sheet of the underlying row of sheets. The exposed longitudinal edges of! the sheets are thus free l i, and apt to be raised from the supporting surface by the force of the wind blowing against the roof or are apt to warp due to weather conditions.

The main object of the present invention is to provide a roof covering of the type mentioned, wherein the exposed longitudinal edge of each sheet is held down by means carried by the underlying row of sheets, the arrangement being such that water cannot find its way through the covering, or in other words a weatherproof covering is obtained.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the ap pended claim, without departing from the with the present invention; 'Fig. 2 is a' similar view, on a larger scale; Fi 3 is a section taken on line 3 3 of ig. 2; Fig. 4 is a section taken on line 4 4 of Fig 2; Fig. 5 is a view similar to .the one shown in Fig. 2 of a modification of the invention; Fig. 6 is a section taken on line 6 6 of Fig. 5; and Fig. 7 is a section taken on line 7 7 of Fig. 5.

Referring now first to Figs. 1 to 4, inclusive, of the drawings, the numeral 10 indicates a supporting surface on the roof construction, to which the covering is to be attached. The covering is made up of strips or sheets 11 of any suitable roong material, for instance of water-proof felt,

that is coated with crushed slate, each sheet being of substantially oblong configuration, its length exceedin considerably that of its `width. Each o.' these sheets is provided with a. plurality of equidistantly spaced slots 12, which extend at. right angles to the longitudinal center line of the sheet from one of its longitudinal edges to approximately said center line. Adjacent each slot that is fastened to the sheet a flexible, preferably, metallic strip 13, said strips abutting against the underfaces of the strip and being secured thereto by means of prongs 14, which are made integral with and extend through the sheet andare then bent against the upper face thereof. The free ends of the strips 13 extend into the respective slots 12, and are adapted to be bent through the slots over the `upper face of the sheet.

The operation of this device is as follows: In laying the sheets, the. same are fastened to the supporting surface and are disposed thereon in the manner of ordinary shingles. Each succeeding sheet is staggered in relation to the underlying sheet and overlapping two' underlying sheets, as clearly shown in Fig.` 1 of the drawings. Each sheet is secured to the supporting surface by a row of nails, denoted in the drawings by the numeral 15, care being takenthat"` the Asaid nails do not penetrate the underlying sheets. After the sheets have been secured in the manner indicated to the supporting surface, the strips 13 of an underlying sheet are bent over the free exposed edge of an overlying sheet, thereby holding the said exposed edge firmly in position, preventin it from being lifted by the force of wind or otherwise.

The slots 12 are provided in the sheets, to give the roof covering the appearance of ordinary shingles.

The modification illustrated in Figs. 5 to 7, inclusive, of the drawings differs from the one above described in that the strips 13 thereof are made integral with the sheets 11. In this instance, the sheets are made of metal. Otherwise the construction and operation of the elements are the same as Lacayo? of those described in connection with Figs. 1 to 4, inclusive, of the drawings.

Attention is called to` the fact that the covering herein described is not limited in its use to roofs, but may be employed in connection with building walls, etc.

What I claim is The combination with a supporting surface, of aplurality of overlapping sheets of covering material attached thereto, each sheet being provided with a plurality of equidistantly spaced parallel slots, and a strip carried by each sheet in alignment with a slot adapted to be extended through said slot and bent over the free exposed edge of the overlappingsheet for securing said edge in place.

Signed at New York, in the county of New York and State of New York, this th day of January, A. D. 1922.

MAX RACHLN.
