UNITED STATES PATENT OFFICE 2,122,702 INSULATED BURIAL VAULT Mathias A. Wagner, Mount Angel, Oreg. Application May'18, 1937, Serial No. 143,309 3 Claims. (01. 72-7) This invention relates to burial vaults of the individual type that are set into the earth so that the ornamental top member is just above the surface. The above type of vault is being largely em ployed and has numerous desirable features look ing to permanency; but the known art has one weak point, that the top does not provide suffi cient insulation to prevent sun heat from pene 10 trating the vault proper. The object of the present invention is to pro vide an insulation member that has high insulat ing value and at the same time possesses moisture absorbent qualities in a superlative degree, bear “ ing in mind that disposal of moisture in the con tained air of the vault contributes very markedly to the desired end, for as is well known substan~ tially dry air is a far better insulating medium than humid air. I accomplish the objects of the invention by an insulating slab that seals the vault proper, below the exposed top member in a manner supe rior to what has been done heretofore, by the employment of new materials for the purpose, ll) 5 assembled in a new structure. Drawing accompanies and forms a part of this speci?cation which, taken with the written de scription, constitutes a complete disclosure of my new vault. so In the drawing, Fig. I is a longitudinal side elevation, partly in section; Fig. II is a top, plan view; with the top and seal removed; Fig. III is a section on the line III-III of Fig. I. The vault proper, l, is aconcrete box-like mem her with an open top‘ and a moulded shelf 2, a short distance below the top. It will be made of ' well selected materials and completely water 40 proof according to the known art. The slab 6 is a slab-like mass of diatomite, of the best obtainable grade and should be dried to not over 6% moisture content by weight. It is tamped loose into the shell-like structure of the slab, before the application of the top member. 5 The shell is composed of a preferably arched bot tom 9, a top l0, end walls II and I2, and ?anges I5, adapted to rest on the shelf 2. The shell is moulded of a highly porous aggregate mixed with Portland cement and preferably reinforced as by expanded metal at H5. The shell aggregate in its best form is a substance made from a natural Wyoming mineral found in a deposit at Encampment, Wyoming, of essentially silicon, magnesium and aluminates, that has the peculiar 15 property of expanding when burnt so that its weight decreases from about 80 pounds per cubic foot to less than 10 pounds with a corresponding increase in bulk. It is highly porous and has a high insulating value, making it especially suit able for the purpose herein, though a high grade of cinder concrete or other concrete with a po rous though strictly mineral aggregate will serve less efficiently. The material is a commercial product known by the trade name of mikolite. The slab is preferably made by first moulding the side and end slabs like planks, laying the bottom slab in a mould and placing the ends and sides in situ in the soft bottom material. After setting, the inside is ?lled with diatomite as here tofore described and a comparatively dry mix of the porous cementitious material is applied as the top H]. Making the slab 6 in‘ this manner obviates the necessity of leaving any wooden form material in the slab, which is to be avoided. Provision of an insulating slab and applying it to a vault in the manner illustrated and described results in a very much improved structure and is believed to completely solve the problem pre sented but left for solution by previous structures. An ornamental top 4, may be cut from granite, In this speci?cation, diatomite is used as an marble or other natural stone or it may be made of terrazzo, art marble or other dense non-porous material and styled as desired. In use, the vault proper will be set into the expression indicating diatomaceous earth of high purity, the grade found naturally in the deposits earth with its top just below the normal surface, the casket will be placed within and the insulat ing slab, indicated in general by the numeral 6, will be placed within the vault I, to rest on the shelf 2. A dense concrete seal 1, will lock the slab 6, to the vault I; a heavy coat of bitumen 8, will be applied to occupy the position shown in the drawing, to complete the sealing of the vault and particularly to seal the top of the slab 6. will serve in a correspondingly efficient manner. at Terre Bonne, Oregon, being taken as a stand ard of excellence, though grades of lesser worth Having disclosed my invention, what I claim as new and desire to secure by Letters Patent, lSZ-— 1. A burial vault comprising a box-like struc ture with a removable top and an insulating slab positioned on an integral shelf below the top, the said insulating slab being characterized by being constructed of cement concrete made of porous 2 ' ' 2,122,702 “~41: aggregate to form a shell de?ning‘ an interior 7 porous cement shell de?ning an interior enciése'd space, the said space being ?lled with dried dia tomaceous earth. 2. In a burial vault, a vault member, a top adapted to be sealed thereto and an insulating and moisture absorbing slab positioned within the vault below the top and over the vault portion, a sealing material between the vault structure and the slab, the said slab being characterized by a. space ?lled with dried diatomite._ 3. An insulation slab for a burial vault of the character described, de?ned as a generally rec~ tangular prismatic body of absorbent diatoma ceous earth material about which is a casting of porous cementitious material comprising a slab like shell that surrounds it on all sides. .
