HENRY c. THOMAS, or noon VIEW, NEW YORK.
INSULATED METALLIC ROOF.
SPECIFICATION formingpart of Letters Patent No. 283,166; dated August 14, 1883,
Application filed May 17. 1883. (No model.)
To all whom it may concern.-
Be it known that I, HENRY O. THOMAS, of Rock View, in the. county of Oattaraugus and State of New York, have invented a new and Improved Insulated Metallic Roof, of which the following is a full, clear, and exact description.
The invention consists in a metallic tank with an insulated roof connected with the ground by a lightning-rod, as hereinafter described.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Fig. 1 is a plan View of the tank provided with my improved insulated roof, parts being broken out and others shown in section; and Fig. 2 is a cross-sectional elevation of the same, parts being broken out.
The roof is constructed with wood or iron rafters A, on which boards B are secured, which boards extend to the outer edge of an angleiron, 0, secured to the top of the outer surface of the tank D, or building. sheathing, E, is tacked on the boards, then lapped over the edge Cof the angle/iron, and lapped against the outer side and bottom edge of a wooden strip, F, held to the bottom of the horizontal flange of the an gle-iron by bolts.
G passed through the said flange and strips, as shown. The edge of the asbestus sheathing is tacked to the strip F. The heads of the bolts G' are below the asbestus sheathing, and are countersunk in the upper surface of the horizontal flange of the angle-iron.
An asbestus A sheet-ir6n covering, H, is placed 011 the sheathing E, and projects beyond and down over the edge of the angle-iron. A series of conductors, J, extend over the roof, and are connected with the edges of the metal covering H, and are carried down to the ground and connected to a gas-pipe, K, surrounding the tank and, buried in the ground. A conductor extends from the pipe K to marshy or other moist ground.
The asbestus insulator makes the tank fireproof, and is a perfect electricity-insulator.
mediately pass down the conductors J, it will pass down the metal covering H, and then through the conductors to the pipe K. The lightning will not leave the good metalv conductor and pass through'the asbestus non-conductor or insulator. Likewise it is not apt to leave the good metal conductor and pass through the wooden. strip F.
I am aware that it is not broadly new to con nect a metallic roof with the ground by a lightning-rod; but
WVhat I do claim as new, and of my invention, is
A metallic tank having its roof insulated and connected with the ground by a lightningrod, substantially as shown and'described.
