, ROOF CONSTRUCTION.

-provements 1n Roof Constructions, of which theiollowing is a specification.

Thisinvention relates to roof constructions andit comprises a roof for a tank or j the like niade of sectionsof metal crimped joint comprlsing or'lts e ulvalent and' hooked along their edges and soldered to each other the roof being placed upon the tank or other structure with a loose connection therebetween, said roof being sealed to the side of the tank by an expansible member or expansion joint, the expansion a continuous strip of lead and being secured to the upper e ge of the tank; all las more fully hereinafter set forth and as claimed.

In constructing a tank to hold oils and other liquids, it is desirable to provide a leak-proof-'connecton or sealing member between the ,tank and its roof and it is also necessary to provide for the expansion and contractlon of the metal due to changes in temperature.l In prior constructions of this character attempts have been made to construct a tank whlch is leak-proof,but in such constructions no allowance was made for the expansion and contraction of the parts. In any construction where the edge of a tank roof 1s secured directly to thetank or is indirectly secured to the tank through the use of some rigid element, the desired result. is

not obtained. In veryhot weather the roof expands to such a degree that it is apt to open a seam and in colder weather it may contract to such an extent as to break the connection between the roof and the tank. In some construotionsprovision has been made' for expansion and contraction but without securing a leak-proof or hermetically sealing connection.

In the present invention we provide` a tank with a roof the medium of a {iexi'ble expansion ]o1nt which permits expansion and contraction of the various elements, and at the same time,

we provide a construction which is entirely leak-proof. When used on an oil tank, this construction prevents the escape of gases and va ors and prevents inflow of air into the tank. r

In the present construction a, continuous Specification of Letters Patent.

secured to the tank through y expansion strip of lead is secured to the edge of the roof, and the shell of the tank is provided with an angle iron at its upper edge, 'the expansion strip embracing the angle iron and being secured to the shell of the tank.

In the accompanying drawings we'have shown several advantageous embodiments of this invention. In this, showing- Figure 1 is a partial plan view of a roof lonstructed in accordance with our invenion;

Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1 showing the expansion strIip made of lead; and

1g. 3 1s a similar view showing-,an expanslon strip made of corrugated tin. :jg

In the accompanying drawings'letter'A designates the tank as a whole. It is provided with a roof B. The roof as shown consists of a-plurality of sections 1 which are crlmped along their edges and hooked to E each other. Solder may be employed to insure perfect joint between the sections. The tank is provided with the usual rafters 2 for supporting the roof and a sheathing of wooden strips 3 which rests upon the rafters and forms a foundation for the roof. Angle iron 4 is secured to the shell of the tank at its upper edge. The roof is not connected rlgldly to the shell of the tank or to the angle iron carried at the top of the tank, but is provided with an expansion strip 5 by means of which a flexible connection is made. In Fig. 2 the expansion strip is shown made of sheet lead and in Fig. 3 the expansionv strip 5 is made of corrugated tin. Other sultable matter, such' as fabric water-proofed with flexible oil-proof mater1al such as chromated glue, viscose cellulose, etc., may be employed for this purpose. .The expansion strip is soldered to the edge of the roof at 6 and extends over the outer edge of the angle iron, embracing the angle iron and 4is secured to the shell of the tank between the tank and the vertical leg .of the angle iron b bolt 7. Rivets or bolts may be employed or this purpose, and the expansion strip may be calked on top between the angle iron and the shell. y

When a roof of this character has lbeen assembled, the connection between the tank and the roof is leak-proof, and if'the'tank contains volatile liquids the escape of vapors and gases is prevented. Any inflow of air is also prevented. As the roof is not rigidly Patented Sept. 23, 1919.

climate, even where it will 'be subjected to marked changes inl temperature. When the expansion strip is made'of lead or other metal, an ebrcellent lightning arrester is provided. If. a -bolt of lightning should hit the roof of the tank, it would pass through the metal expansion strip and down the metal side of -the tank Vto the ground.

What we claim "is 1. A roof for storage tanks and the like comprising a Inetal covering for the tank, an angle iron secured to the edge of the tank at "tle rtop thereof, with a loose connection between said metal covering and l said angle Iron, an expansion strip of ilexible metal secured to the edge of the roof, said expansion strip embracing said angle iron and being secured to the shelly of the tank. v g A 2. A roofforstorage tanks and the like comprising a metal covering for the tank, with a loose connection between said metal images covering'- and said tank, an expansion strip of exible metal secured to the/metal covering, and to the tankIi said strip forming a' leak-proof connection between the tank and the roof, and permitting expansion and contraction of the same.

3. A roof for storage tanks and the like comprising a'metal covering for the tank, an angle 'iron secured to the edgeofthe tank at the top thereof, with a loose 'connection between said metal covering andA said angle iron, an expansion strip of lead secured to the edge of the roof, said expansion strip embracing said angle iron and being secured to the shell of the tank.

4. A roof for storage tanks and the like comprising a metal covering for the tank,

with a loose connection between Said metal covering and said tank an expansion strip of lead secured to the metal covering, and to the tank, said strip forming a leak-proof` connection between the tank and the roof,

and permitting expansion and contraction of` the same. Y
