SHEET-METAL ROOFING.
SPECIFICATION forming part of Letters Patent No. 511,775, dated January 2, 1894.
Application filed September 14, 1893- Serial No. 485,485. (No model.)
To aZZ whom it may concern:
Be it known that 1, WILLIAM T. H OLZBACH, a citizen of the United States, residing at Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Sheet-Metal Roofing; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to means for fastening rectangular plates or sheets of Iiat metal roofing to the roof boards and of forming and capping the joints, and its object is a device whereby, without the use of nails or any perforation of the plates, they are securely fastened to the roof boards, and a joint between them is made that is absolutely impervious to water, while the expansion and contraction of the plate material are wholly, and at all times, without injurious effect, thus removing the chief objections that have hitherto existed to sheet metal roofing, namelyz-(first) liability to become leaky by reason of corrosions resulting from the entrance of moisture into perforations occupied by nails or screws, enlarged by expansion and contraction; (second) loosening of nails, or other means of fastening, by expansion and contraction of the plates; and (third) inability to seal the joint beyond danger from the same causes. I accomplish this object by the means hereinafter described and illustrated in the drawings, in which Figure 1 is a side view of a section of a roof board carrying the staples s and the doubly curved wire w, ready to receive and retain the angled sides of the roofing plates 19. Fig. 2 is a cross section view of the same on the line so wot Fig. 1. Fig. 3 is aside view of a section of a roof board carrying the staples s and the doubly angled wire w ready to receive and retain the angled sides of the roofing plates 12. Fig. 4 is a cross section view of the key-cap c. Fig. 5 is a view as in Fig. 1 with the plates 19 in place, secured by the wire w. Fig. 6 is a cross section view of the same. Fig. 7 is a side view of a section of roof with the key-cap c in place and complete. Fig.8 is a cross section view of the same. Fig. 9 is a side view of two sections of the key-cap c, the ends joined by an overlap, showing in dotted lines the edges of the portions in each that are turned upward at an acute angle forming the spaces a a; and Fig. 10 is a side View of a section of the key-cap, 0, showing the triangular notches 71 therein.
Similar letters refer to similar parts in all views.
The novel features of my invention consist of the wires 10 and to, either for use as may be preferred, attached to the roof by staples, or other suitable means, and extending upward, doubly curved or bent to angles as shown to clasp over the edges of the contiguous upward projecting portions or angles of the plates 10 upon their right and left sides alternately; and also of the key-cap c which is a strip of metal of suitable breadth bent 011 the line of its breadth center to an acute angle, each edge being again bent inward to acute angles forming the spaces a a, which, when the key-capo is in place covering the contiguous upward angles of the plates 19, hold the curves of the wire to that are convex to the roofing board, or the downward pointing apices of the wire to. The rectangular and similar roofing plates p, having a narrow strip on two sides turned upward at right angles with the surface of the plate are not new.
The new features above pointed out will be more fully understood when their methods of application, and uses, are described, which I will now proceed to do.
Most conveniently the workman strikes a line upon the roofing boards or slats from eaves to ridge along which at suitable intervals he drives the staples 5 through which the wire w is drawn and curved vertically to, preferably, a half circle, after which each staple by a blow of the hammer is tightened into the board. By the use of a tool provided for that purpose the upper portion of each curvature is bent over laterally to an acute angle, such bends being alternately right and left. One bend for each plate is usually sufficient and separate short wires may be used if the plates are large, for economy. The lateral bending of the curves brings the portion of the wire w that has thus become convex to the roof boards at such exact dis- IOC above described would also be within the scope and spirit of my invention.
lVhile I prefer staples as a means of fastening any other means that will secure the wire to the roof may be used.
"For larger operations, and to facilitate the work of the practical roofers, the wires t0 and w, or any variations of them, may be made in quantities by machines constructed for that purpose, and in lengths to be cut as used, the bends being better effected when the wire is hot. When the wire to or w is attached as above stated, the plates p are pushed to place on its right and left sides, lateral bends clasping over the upward projecting portions or angles of the plates as seen at Fig. 5. The'key-cap c, which has been described, is then placed over the contiguous upward projections or angles of the plates 13, joined, and secured to the roof boards as explained, and, beginning preferably at the lower end is slid to place, the lower portions of the curved part of the wire to that is convex to the roof board, or the downward proj ecting apices of the wire to, being clasped within cept that triangular notches are cut from the lower edges upward in the two sides of the key-cap c at suitable intervals, to permitthe curving necessary.
My invention will now be understood and its value in the art of sheet metal roofing, as the full accomplishment of the object stated in the beginning of this specification, will be appreciated.
What I claim is 1. In sheet metal roofing, in combination with sheet metal roofing plates having the edges upon two sides turned upward at right angles, a wire presenting a series of bends, upward and downward, from the roof boards to which it is secured by a fastening between each bend, the upper portions of the bends being again bent, alternately right. and left, to acute angles with the vertical portions, substantially as described and for the purpose expressed.
2. In sheet metal roofing a roof formed in combination by the sheet metal roofing plates 19, having their edgesupon two .sides turned upward at right angles; the wire to presenting a series ofupward curvatures, secured to the roof boards or slats between each curvature, the upper portions of each curvature being similarly bent alternately right and left to acute angles with its vertical portion; and the key-cap 0 being a suitable strip of metal bent on the line of its breadth center to an acute angle and having the lower edge of each side turned inward to acute angles forming the spaces Ct at, all substantially as described and for the purpose expressed.
' In testimony whereof I hereunto affix my signature in the presence of two witnesses. WILLIAM T. HOLZBAOH. WVitnesses:
