ASPHALT VA'ULT.

Application led May 7, 1924. Serial No. 711,518.

I To all whom it may concern.'

a citizen of the United States of America, residing in the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Asphalt Vaults, of which the following is a specification.

Numerous attempts have been made to produce a permanent moisture-proof burial vault or container to receive and enclose a coffin or casket to be buried in the earth, the object being not only to exclude moisture but to permanently protect and preserve the coin and the body.

To this end the structure must not only be water-proof but non-corrosive and suliciently rigid to permanently resist the ressure of the earth. j Such containers ave been made from metal, Portland cement, concrete with or without reinforcement, and from metal lined or filled with asphalt, the asphalt being between two metallic casings or walls.

The Portland cement concrete is not eective because while it is reasonably permanent, it is porousand not water-proof, and

the entrancebf moisture results in decay which cannot be long deferred. The metallic vaults are not permanent, none of the available metals being sufficiently non-corrosive. The vaults which have been described as made of asphalt between metal walls or in some instances enclosed between iwalls of wood, are subject to substantially in accordance withthe specic-ations is necessarily soft and relatively fluid, owing to its fluidity soon leaves the inner container or casing exposed to decay or corrosion,

' which takes place as certainly as with metal or wooden vaults, though the decayA may be deferred `for several years.

The present invention relates t0 an asphalt vault or more particularly to an asphalt or bituminous mastlc .for the \manufacture of a vault meeting all the require-- ments of the conditions presented, i. e., a vault for enclosing a casket and body to be buried in the earth and having sulcient rigidity toresist` permanently the pressureF of the earth, and being absolutely moistureproof.y In my co-pending application Ser. No. 711,519, I have described and claimed plete the structure.

"a reinforcing frame for an asphalt vault, Be it known that I, lVILLIAM E. SHEENE,

the same being coated with asphalt to com- In the present application I have described 'and claimed an asphalt vault, the claimsbeing specific to such a structure composed of asphalt which is sutliclently rigid to resist the earth pressure when suitably reinforced, claiming .the constituents, properties and features of the vault as dependent upon the k lasphaltic material.

The mastic which is the subject of the invention 1s cast upon a metal frame or reinforce which shapes and supports the structure, the important featuresof the mastic are that in addition to being capable of bemg melted, poured and molded to advantage, it is, when set, sutliciently hard to ad- Y I here tothe frame and to resist and support the pressure of the earth, upon the frame,

spanning the meshes of the reinforce and A force and a permanent protection to the casket and body, and the mastic is at the same time absolutely vand permanently moisture-proof, so that the most hydroscopic and sensitive substances may be placed on the bottom of the container or vault, and the vault can be submerged for a long period i without evidence of the hydroscopic substances thus exposed having been `in any way attacked by moisture.

In the preferred form the' mastic consists of a high melting point asphalt mixed with limestone dust, fullers earth or infusorial earth and sand or grit. In some instances slate dust has been used instead of limestone dust. In preparing ,the composition I preferably use a blown asphalt which may to best advantage be made of petroleum or'petroleum residue heated and blown until the volatile portions are p-ractically eliminated or oxidized, and until the resulting material has a melting point appreaching 285 Fahrenheit when it will also have the desired property of rigidity whenmixed with the appropriate ingredients and permitted to set or harden and subjected to the earth temperatures and pressures `under burialconditions.v A California orMexican petroleum or residue thus treated is found satisfactory. The preferred proportions are 16% bitumen or asphalt as above, 34% limestone dust, fullers earth or infusorial earth, and.4 50% of sand or other suitable grit. The materials and proportions may be varied to a considerable degree, and a flux which does not unduly interfere with the hardness `of the material when set may be used. 1

The materials stated above are mixed together and cooked, or preferably separately heated, and then mixed and further heated until they form a paste or mortar'capable of being poured and mlded.l Treatment at a temperature of 4500-Fahrenheit. has been found advantageous.

A' suitable reinforce having the shape of the vault or rather two separate reinforcing .members, one having the shape of the vault and the other. 'having the shape of a cover,

are placed .in molds and the material is poured, hardening in the desired form.

onthe line 3, 3 of illustration includes a vault 1 of asphaltA mastic adapted to enclose asingle coin or casket 2, and a cover 3, also of asphalt mastic, the vault and cover being reinforced by means of metal frames 4 and 5, respectively, embedded in'and protected by the mastic. The contact between the vault and cover is closed and sealed by suitable'sealing means 6 of softer bitumen or asphalt adhering to adjacent asphaltic surfaces of the vault and cover, making the structure, when closed permanently, air and moisture-proof at all points, which is believed to be a result.

not previously attained in burial containers of this general type;A

More particularly the vault reinforce consists of longitudinal angle irons 8 extending along the top edges of each side, transverse an leV irons 9 extending across the bottom an up each side, and end angles 10 extending vertically across the ends and turned under the bottom, so that they crossthe transverse angles 9, the depending flanges of the end angles being cut away at 11 to pass the transverse angles. The vertical angles IO and the transverse angles 9' are connected by reinforcing rods or wires 14 which are in turn connected by upright Wires orrods 15, the intersections in all instances vbeing preferably spot-welded or otherwise fastened.

In the form shown the wires are omitted at the bottom and there is a plate 16 which may be turned up at vthe edges at 17, and which reinforces the entire bottom, f the plate being preferably separate from the other reinforce.` Y.

The cover reinforce consists of angles 18 extending longitudinally at the sides and transversely at 19 at the ends, the members 18 and 19 being preferably formedv in a ,single piece, the transverse anglesf20 and longitudinal and transverse. wires or rods 21 and 22. i

The cover' and vault are formed by placing these frame members in suitable molds,

'pouring and removing the mold members. l
