June 14, 1932. J, E BURNS 1,863,186 I PROTECTED METAL ART ICLE Filed Nov. 4. A195o lPatented .lune 14, 1932 UNITED sTATEs PATENT OFFICE JOHN EDGAR BURNS, OF .AMBRIDGZEL PENNSYLVANIA, ASVSIGNOR TO H. H. ROBERTSON COMPANY, OF PITTSBURGH, PENNSYLVANIA, A. CORPORATION OF PENNSYLVANIA PROTECTED METAL ARTICLE Application filed November 4, 1930. Serial No. 493,326.
'This invention relates toan asphalt-protected metal article and particularly to an asphalt-protected metal sheet in which the steel or other metal sheetV has adhesively afb fixed to it by asphalt or like bituminous material`layers of fibrous material saturated with as halt or like bituminous material, which fi rous material is also protected by a coating or layerof asphalt or like bitumi-4 nous material which is united or bonded with the asphalt in the fibrous material.'
In protected metal sheets of the character described, as now vgenerally constructed and known to me, the layers of fibrous material are folded over the side edges of the metal sheet to protect from corrosion the metal sheet, usually of steel, by the asphalt with which the fibrous material is saturated, and the protecive coating is applied to the fibrous laye s to contact therewith throughout their area\ and thereby seal the steel sheet from the weather and the injurious effects l of acid and alkali-fumes.
A protected metal sheet of this character is disclosed in United' States Patent No.
.1,277,755 dated September 3, 1918.
The present invention has for its object to provide a protected metal sheet of this general character in which one or both of the sideedges of the steel or other metal sheet may not be covered by the saturated fibrous layers yet are protected by the coatinglayer which is firmly united with fibrous 'layers/in such manner, as Will be described,
to properly'protect the side edge or edges of the metal sheet4 and enable the protected' metal sheet to be bent at or near its side edge or edges Without cracking or otherwise in]uring the protective coating so -as to ex.
40 pose to the atmosphere the metal sheet'at such bend.
To this end, the steel sheet having the fibrous layers applied thereto and having one or both of its side edges exposed or uncovered by the fibrous layers has applied to the exposed side edge a substantially narrow strip or member, which will be hereinafter termed thc binding strip or member and which may be of metallic or non-metallic material and provided with side walls which of this specification.
overlay the fibrous layers and are provided with edges and With a plurality of openings or perforations at the rear of the edges of said side walls, so that when the protective layer or coating is applied, the-said coating will not only cover andshe united with the unrcpyered portion of the fibrous layers but also will cover the edge strip or binding member and will pass through the openings or perforations ltherein and be united with 00 the portion of the fibrous layers` which are covered by the side walls of the binding strip or member, and thereby effect asufficiently strono union between the protective coating and tie. fibrous layers at the edge my of the steel sheet to enable the protected metal sheet to be bent at or near its normally exposed edge Without danger of cracking or opening up the protective coating adjacent the edges of the side walls of the binding strip or member. j
A protected metal sheet embodying this invention is capable of being made with steel sheets of different Widths and may be provided With relatively sharp bends or flanges, to enable them to be used on buildin s where a protected metal sheet of-normal width and construction in which the fibrous layers are folded over the side edges of the metal sheet couldnot be used.
These and other features of this invention will be pointed out in the claims at the end Flg. 1 represents in plan view one construction of protected metal sheet embodying this S5 invention;
Fig. 2, a plan view 0i. thesheet shown in Fig. 1 with the layers broken away; J
Fig. 3, across section on an enlarged scale of the protected metal sheet-shown" in Fig. 1, o0 taken on the line 3 3;
Fig. 4, a cross section of the protected metal sheet shown in Fig. 1 before the protective coating is applied;
Fig. 5,'a cross section on an enlarged scale4 05 of a modified construction of protected ,metal'f 'sheetembodying the invention, and v l Figs. 6 and 7, cross sections of the protected metal. sheet showing modifications of the binding member.
Referring to the drawing represents a metal sheet, preferably of steel, which has affixed to its upper and lower surfaces layers 12, 13 of fibrous material, preferably asbestos or like felt which is saturated with asphalt or like bituminous .material 14. The saturated fibrous layers 12, 13 as shown in Figs. 1, 2, 3 and 4 are of substantially the same width as the metal sheet 10 and are adhesively affixed to the metalsheet by a layer or film of asphalt or like bituminous material indicated by the heavy black lines 15.
The metal sheet 1-0 and the fibrous layers 12, 13 afhxed thereto are sealed Within a protec- 15 tive coating or envelop 18 of bituminous material, preferably gilsonite fluxed with cotton seed pitch,which protects the steel sheet from corrosion and the action of acid and alkali fumes in the atmosphere, and provision is made for edecting a firm attachment of the protective .coating 18 with the fibrous layers 12, 13 'at the side edges of the metal sheet 10, so that the protected metal sheet may be bent at its side edges without liability of cracking or opening up the protective coating at such bend or bends.
For this purpose the metal sheet 10 having the/fibrous layers 12,\13 applied thereto, is provided at its uncovered sideedge or edges with a binding member 20, which is shaped to cover the exposed edge of the metal sheet 10 and provide side walls 21 which overlay the fibrous-layers adjacent to the edge of the `metal sheet, and said side walls are provided with a plurality of openings 23 (see Fig. 4) located at the rear of the front edge 24 of the side walls, so that the material of the coating or protective layer 18, whichv is plastic when heated, may pass through said openings and 4U unite or bond with the saturant in the fibrous layers 12, 13 behind or at the rear edge of the side walls of the binding member and thereby securely fasten the protective layer 18 "to the fibrous layers 12,13 at the rear of as well as in front of the edge of the side wall 21 of the binding member, and thus prevent movement of the Coating layer 18 with relation to the I front edge of the binding member when the sheet is bent at its edge toi" protected metal form aV flange, and thereby avoid liability lof the coating member 18 being cracked or opened up, so as to expose the steel sheet 10 `to corrosion and the bad effects of acid and a alkali fumes.
vlThe binding member may be of sheet metal and have the holes or openings 23 punched therein and 'sufficient in area to obtain a firm union of thecoating member 18 with the fibrous layers, or said. binding member may be made of an open meshed fabric either 4metallic or non-metallic as represented in Figs.6and7. .l
- When an open meshed fabric issused as the binder member, it may be provided with layers a core 25 to contact with the exposed edge of the steel sheet.
The brous layers 12, 13 may be separate when both edges of the steel sheet are exposed,vor they may be inV one piece and folded over one edge of the metal sheet, as shown in Fig when only one edge of the metal sheet is exposed.
A protected metal sheet provided with a perforated binding member applied to one or both edges of the steel sheet, enables the latter to be obtained by cutting a steel sheet, of normal or standard Width, such as is used in the production of the protected metal sheets disclosed in the Patent No. 1,277,755, and thereby avoids the necessity of the manufacturer of the protectetd metal sheets 0f normal width, to carry steel sheets of different widths in stock to meet conditions of use wherein protectetd metal* sheets of narrower widths than the standard protected Ametal sheets are required. v
