THOMAS W. H. MOSELEY, OF CINCINNATI, OHIO.

ATTACHING IRON ROOFING.

Specification of Letters Patent No. 23,600, dated April 12, 1859.

T o all whom it may concern:

Be it known that I, Trios. IV. I-I. MOSELEY, of Cincinnati, in the count-y of Hamilton and State of Ohio, have invented certain Improvements in Iron Roofing, and that the following is a full, clear, and exact description of the principle or character which dis tinguishes it from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure 1 is a perspective view of the roofing. Fig. 2 represents one of the roofing plates.

My invention consists in an improvement in iron roofing described and represented as follows:

Upon the rafters a a, which may be of wood or iron, arched or straight, I secure byA bolts or screws a series of iron chairs c, c of the .form shown in Fig. l. The dovetail opening' in the chairs is so formed as to embrace the lower half of the iron rails or pur lins c, c, and allow them to move with freedom in the chairs. These chairs are at suitable distances apart in parallel rows upon the several rafters and the lower half of each purlin is passed through each series of chairs. The purlins are formed alike above and below and a cross section would somewhat resemble the letter I, and is in fact what is termed in trade I-iron. To the under side of the roofing m which I prefer to make of corrugated metal I attach by bolts or screws dovet-ail pieces of metal n of form corresponding to the form of the chairs and these pieces I call anchors. They are arranged in lines corresponding to the lines of the chairs c and these anchors embrace the upper flange of the purlins as shown in Fig. l. The sheets of rooting are drawn over the purlins lengthwise and there is sufficient play left for the purlins in the dovetail openings of the anchors to accommodate the expansion and contraction of the rooting, in the direction of the rafters, while the eX- pansion and contraction in the direction of the purlins and the expansion and contraction of the purlins also are accommodated to any extent by the freedom of motion of the purlins in the chains and anchors.

I have thus constructed a perfect metallic rooting of great strength and of the utmost simplicity both as regards the manufacture of the several parts and the putting together, not a bolt or screw being required to secure the roofing plates and a roof which can never suffer from the greatest ranges of atmospheric temperature.

That I claim as my invention and improvements in iron roofing isl. Securing t-he metallic rooting to the ribs or purli ns so that it may slide or move freely upon and in the direction of the length of the purlins substantially as herein set forth.

2. I claim securing the purlins to the rafters of the building so that they may have freedom of motion in the direction of their length substantially as herein set forth.

8. I claim the combination of the chairs c, double flanged rail e, anchors n and metallic rooting m as herein set fort-h.

THOS; IV. H. MOSELEY.
