FIBER GLASS BURIAL VAULT 2 Sheets-Sheet 2 Filed March 27, 1961 INVENTORS d w M in i2 A .m m r U United States Patent 3,159,901 FIBER GLASS BURIAL VAULT Arthur C. Harrington, Whiteford, Md. (R0. Box 338, Aberdeen, Md), and Ray Hall, RD. 2, Box 171, Street, Md.

Filed Mar. 27, 1961, Ser. No. 98,401 4 Claims. (Cl. 27+?) This invention relates to containers or receptacles of various kinds and composed of various materials, and more particularly to containers or receptacles which are capable of being sealed and made hermetically tight against surrounding influences both from within or without.

' The invention relates further to containers or receptacles in which objects are placed and retained for protection against the elements and specifically to burial vaults in which caskets with persons therein are received and interred.

Burial vaults of various kinds and of a variety of materials have been produced including of wood, concrete, metal, and other materials and with covers of various kinds. These have been unsatisfactory because of excessive bulk, and weight, with consequent excessive transportation expense as a result of both their weight and size, and requiring that they be handled on y with a large vehicle and requiring multiple personnel and energy. Also certain of the prior devices lacked effective sealing and durability.

It is an object of the invention to overcome the difficulties enumerated and to provide a relatively simple, light weight, burial vault, of fiber glass, and which is of minimum bulk and consequently can be handled by a single individual including both during transportation and the lowering of the same into the earth, can be hauled in a small vehicle such as a pickup truck or the like, all of which one result in a substantial saving in material, manpower, space and transportation costs and which device is of maximum efiiciency and durability.

Other objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings wherein:

FIG. 1 is a perspective of a vault and cover;

FIG. 2, a perspective of the cover inverted;

FIG. 3, a perspective of the vault with the cover in place thereon;

FIG. 4, a longitudinal section on the line 44- of FIG. 1;

FIG. 5, a central transverse section on the line 5-5 of FIG. 3;

FIG. 6, an enlarged transverse detail section; and

FIG. 7, a fragmentary part elevational view illustrating how the articles can be stacked' Briefly stated, the invention is a burial vault or hollow container or receptacle and a cover therefor, all of fiber glass and capable of being bonded together to provide a single hermetically sealed receptacle of maximum strength, resistance to chemical reaction and consequent durability, as well as a receptacle and cover which can have the cover inverted and stacked with other receptacles and covers, with the receptacles and covers longitudinally reinforced, by including reinforcing ribs in the uprights walls of the receptacle which serve to assist in resisting upward and lowering movement in the earth, the cover and upper rim of the receptacle being enlarged and providing a roof having an overhangand with interfittin-g tongue and groove portions and the relatively thin walls and cover whereby the overall device is relatively small and light and without excessive bulk and weight. a

With continued reference to the drawings, in the manu- "ice facture of the device a suitable base or mold is provided having an external configuration rectangular or of the shape of the vault or device to be'made and on which mold is applied a couple of layers of fiber glass with a waxed and polished exterior, the said fiber glass forming part of the mold.

On the Waxed and polished surface of the mold is applied a brush coat or layer of resin sufiicient to wet down the mold. After wetting down the mold a finishing layer 10 of fine spun glass fabric sometimes designated 1000 cloth is applied. This finishing layer of fiber glass is thoroughtly wetted with a brush coat of resin and then a layer of roving cloth or coarser and heavier cloth 11 is stretched thereover and to which a brush coat of resin is applied.

In order to reinforce the upright walls of the vault one or more reinforcing rib strips 12 is added, such rib strip being generally in the form of a semi-circle or half round with its flat surface against the coarse cloth 11, two of such rib strips being used along each of the upright walls in spaced parallel relation although any appropriate number may be utilized.

After the application of the rib strips 12 which extend, completely around the vault, an additional coating of resin is applied and sealed to the first coarse layer 11, the exterior surface of which heavy layer 13 is given a brush coat to wet it sufliciently to receive a final layer of coarse heavy roving cloth 14 which is supplemented along its upper portion to provide an upstandingflange or lip 27 and an outwardly extending flange 15 having plete smoothness of the surface the mass is allowed to harden in accordance with conditions and which usually occurs in two or three hours. If desired, color may be incorporated in the first and last layers or in all layers if desired.

After the mass has been allowed to harden the receptacle thus formed on the mold, it may be removed in a conventional manner by compressed air supplied through openings in the bottom of the mold at spaced locations. In order to facilitate the separation of the vault from the mold, the exterior walls of the mold may be tapered slightly outwardly. Consequently when a blast of air is admitted through the bottom of the mold into the area between the mold and the vault in spaced locations, the latter will be freed from the mold and can be readily removed. Theresulting taper of the walls, not shown, will also facilitate stacking of the vault and cover as described previously.

The cover is produced in a somewhat similar manner,

it having been found that from four to six intermediatethe four to six layers of a relatively heavy body-giving" roving cloth 20 andthe final more closely woven finishing layer 22 with each of the layers coated with the resin so that it will be thoroughly wet as each additional layer is applied.

handle mold is placed on the end of the cover and is' covered by the fiber glass fabric and the finishing layer which provides the finished handles by which the cover can be moved;

Around the lower edge of the cover there is provided a flanged portion 24 with a depending rib 25 which is adapted to be receivedwithin the groove 16 of the flange 15 and be sealed thereto by sealing means which may be the resin employed or it may be asphalt, bostic or other substance. 7 The "sealing means 26 is. applied after the casket has been placed in'the vault and just before the cover is put in place to form a permanent and water-tight seal between the vault and the cover.

In the application of the handles care is taken to make sure that the handles are sufiiciently distant from the end of the cover that the cover may nest in the body of the receptacle when the cover is inverted, thus to allow the compact stacking of the receptacles and covers with others of like character and size and with the exterior of the smaller vaults of an overall dimension permit their being received within the larger vaults which is not the case wherecumber'some vaults of bulky compositions are employed.

It will be apparent from the foregoing that a burial vault isprovided which utilizes a minimum of material bulk and weight, which can be readily handled and transported with a of manpower and equipment, is capable of being stacked, and when used will provide a permanent sealed structure.

It will be obvious to one skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the dr'awingan'd described in the specification, but only as indicated in-the accompanying claims.
