Letters Patent No. 95,732, dated October 12, 1869.

IMPROVBD METALLIC ROOFING.

The Schedule referredto in these Letters Patent und ranking plrto! the lame To all whom 1t may concern Be it known that I, FRANKLYN' RoYs, of East Berlin, county of Hartford, and State of Connecticut, have invented a certain new and useful Improvement in Metallic Roofing; and to enable others skilled in the art to make and use the same, will proceed to describe its construction` referring to the drawings, in which the same letters indicate like parts.

The nature of this invention consists in so forming the edge of' the sheet that one sheet at a time may be laid, and the edge thereof, outside of the joint, may be securely nailed. Then the joint ofthe next sheet is slid over the joint of the edge just nailed, whereby the second sheet is locked over the joint of the rst, and the'headsof the nails of the first sheet are covered by the second.

The end of the second tier or sheets, ascending the roof, overlaps'the upper ends of thc first sheets and joints sutiicent to prevent driving storms reaching or extending over the upper-ends ot' the iirst or underlaying sheets, and so on, successively, until the entire roof is covered.

.- In the accompanying drawingsv 'Figure l is an end lview 0f two sheets of metal locked together after the manner of this invention.

u represents the .timbering or boarding of a rooi`.

b are the sheets ofv metal. f

c are the joint-formations. f f

d are the projecting edges or fastening edges, which project beyond the joint, for the purposeot' securely nailing the edge of each sheet before the joint of the succeeding sheet is slid over'the joint of the first` e represents the nails passing through the project ing or fastening edge d, thus accomplishing a very im- .poltant object, viz, to so fasten the sheets-as Ato eifectually cover and protect the nail-heads e from any exposure to the atmosphere; in other words, by means of the project-ing edges d, of the metal sheet b, outside of the joint-formation c, one sheet is firmly nailed or securedto theboards or timbers or the roof, and thus' each succeeding or alternate sheet, when slid over the joint-formation of the lst, securely covers the nails by which it is secured, and sojon` alternately or successively, until the whole is completed, and thus secure or lock the joints so as to etfectnally stand against the action of heat and cold, and form a perfect joint.

These joints c are bent or formed int-o shape hy mnchines in common use.

The shape of the joint 'inay be formed round, or inan angle shape, but it is believed that the latter will liest accomplish the desired object.

I believe I have thus shown the nature and construction of this invention, so as to enable others skilled in the art to make and use the same therefrom.

I claim a roof of sheet-metal, oneledge, or both, of the plates, which is nailed through the-projecting edge d, outside of thebent-poltion c, wlchiorms the joint, and is connected to the adjacent sheet, as shown and described, to cover the nailed edge, substantially as set 1r. noirs.A [n s1,
