SHEET-METAL covERING.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application led August 16, 1917. vSerial No. 186,618.

To all whom 'it may concern.'

Be it known that I. TnoMAs D, MILLER, a citizen of the United States, residing at Catonsville, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Sheet- Metal Coverings, of which the following is a specification.

The purpose of this invention is to provide metal sheets of the dimensions suitable for shingles. siding, rooting, etc., with protective coverings which can be readily manufactured and applied by automatic machinery, which coverings not only protect the faces of the metal sheets, but the edges thereof which would otherwise. be exposed to the weather. Vhile the invention is applicable to met-al sheets of various dimensions for various purposes, it is particularly desirable in connection with sheets of suitable size to form shingles, and, for convenience, the invzntion will be described as applied to shing es.

In-the 'accompanying drawing, which illustrates my invention,

Figure 1 is a plan view of a sheet metal strip suitable for forming the core of a shingle;

Fig. 2 is a similar view of a protecting covering, 'adapted to tit the core shown in Fig. 1;

Fig. 3 is a similar View, showing the covering folded at its center around one end of the core, the two halves of the covering being laid against the opposite faces of the core:

Fig. 4 shows in plan view the completed shingle, the marginal edges ofthe Wider portion of the covering being folded over the side edges of the core and overlapping the marginal edges of the narrower half of the covering;

Fig. 5 is a section on the line 5-5 of Fig. 4;

F ig. 6 is a section on the line 6 6 of Fig. 4;

Fig. 7 is a plan View of a .modified form of covering;

Fig. 8 is a similar view of a shingle with the covering of Fig. 7 applied thereto;

Fig. 9 is a section on the line 9 9 of Fig. 8; and.

Fig. 10 is an edge view, partly in section, of the shingle shown in Fig. 8.

Referring to Figs. 1-6, inclusive, of the drawing` a represents a strip of sheet metal of suitable dimensions-to forni a core for a shingle, and b represents the covering. The covering Z) consists of a fabric, preferably asbestos, and it is pre-formed to fit the core, said covering, for one-half of its length. indicated at 1, being somewhat wider than the core, and the other half 2, of the covering,

being substantially of the same Width as the core.

The core. prior to applying the covering thereto, is coated with a cement, preferably asphaltum, indicated at 3,-which protects the core against rust and also serves to secure the covering to the core. In applying the covering to the core, the covering. is folded at its center, along the dotted line Ll, around one end of the core, and the parts 1 and 2 of the covering are then pressed' by rollers on to the oppositefaces of the core, as indicated in Fig. 3. the marginal edges of the narrower part of the covering registering substantially with the marginal edges of the core, while the marginal edges of the wider part of the covering project laterally beyond the core, as shown at l*l in Fig. 3. The margins of the wider part of the cov ering are then folded around the edges of the core and overlapped on the margins of the narrower part of the covering. as shown in Fig. 4, this folding operation being performed by suitable rollers while the asphaltum cement is still plastic.

It isdesirable to protect the edges of the metal core from the weather, and more particularly the lower end, as the lower part of tbe shingle is always exposed to the weather when in use. It will be seen that in the shingle illustrated in the drawing, the protective covering is folded around one end` which may be considered the lower end of the core. and thus this' end is completely v5 and 6, of

it is not so essentialy to cover the upper edge of the shingle, although this may bev done, if desirable, by slightly lei'igthening the covering so that they two parts vthereof will extend slightly' beyond the upper edge of the core.

In applying the coverings to the metal cores, the cores are engage the latter atthe folding line 4,. each core and covering then passing .through the rolls which press the covering on to the core and turn in the marginal edges of the `wider half of the covering.v The coverings can thus be applied expeditiously andcheaply.

In Figs. 7 to 10, inclusive, a modified form of coveringis shown.` This form, while proportioned in the drawing lto suit a metal core of the. dimensions of an ordinary shingle, is well `adapted for sheets of metal of various dimensionsl suited for other buildingpurposes, such 'as roofing and siding.

Referring to Figs. 7-10, inclusive, the covering indicated at b, in Fig. 7, is approximately twice thel length ofthe core a', to which it is to be applied, and the two halves, the cover sheet have marginal portions 5 and 6a, each one-half the length of the sheet andalternately arranged on opposite sides of the sheet. yThedistance between the edge 5b of the part 5 of the sheet, andthe edge 6b of the part 6 of the sheet is' approxin'iately equal to the width of the core-preferably a triiie less than the width of said core, While the marginal portions 5 and 6EL extend outwardly in opposite directions from the lineof the edges 6b and 5", respectively. Vhen the cover sheet is applied to the core', the former islfolded on the line 4f?, around one edge or end of the core, andthe two parts 5 and 6 are then rolled on to the opposite surfaces of the core, and the marginal portion 5a is turned over one of theside' edges of the core and lapped on to the part 6, while the marginal part 6 of the cover is folded around the opposite' edge of the core and lapped on to the part 5, as shown in Figs. 8 and 9. The asphaltum or other cement'used oozing out under the pressure of the rolls serves to secure the fed by automatic niachinery at right angles tothe coverings and cover of fibrous material adliesively secured thereto in fixed relation and extended around one end of 1said sheet and covering the said end, the opposite surfaces and the side edges of said metal sheet, with the portions of the fibrous material which cover the. side edges of the metal sheet adhesively atiixed to the portions of the cover which are affixed to the opposite surface of 'said metal sheet.

3. lA building material comprising a sheet-V inetal core having adhesively secured thereto, in fixed relation, a one-piece cover of fabric entirely inclosing the core, said cover being approximately twice the length of the core and having at its lateral edges two marginal portions each approximately the length of the core, the bodyof said cover extending around one end and covering the facesof the core, and each marginal portion extendingk around onev lateral edge of the core and overlapping and cemented to the fabric on the oppositeface of the core.

4. A building material comprising a sheetmetal core having adhesively secured thereto, in fixed relation, a one-piece cover of fabric entirely inclosingl the core, said cover being approximatelytwice theflengthof the core and havingat its lateral edges twomarginal portions each approximately the 'length of thecore and alternately arranged on the different halves of fabric, the body of said cover extending around one end and covering the faces of the core, and eachmarlginal portion extending around one lateral edge of the core and overlapping and cemented to the fabric on the opposite face of the core.

In testimony whereofI have laffixed my signature.
