Patented Apr. 21, 1936 PATENT OFFICE WATERPROOF BURIAL VAULT Fred J. Mead, orange, N. J., signor to Mead- Suydam Company, Orange, N. J., a corporation of New Jersey Application February 17, 1934, Serial No. '711,631

3 Claims.

This invention relates to a water-proof burial vault that is made up largely of concrete, the concrete itself not being necessarily water-proof. The vault has a cover which is also water-proof and when it is placed upon the body portion of the vault a water-proof joint or seal automatically results.

In carrying out this invention a layer of waterproof material is interposed between the outer and inner surfaces of the body and cover of the burial vault in such a way that the water-proof layer is continuous on all six sides without any perforations or openings therethrough and without any crack or aperture through which water could gain access to the inside of the vault when the cover'is in place.

The invention will be understood from the description in connection with the accompanying drawing in which Fig. 1 is a. side view of an illustrative embodiment of the invention partly in section; Fig. 2 is a section along the line 2-2 of Fig. 1 on a larger scale; Fig. 3 is a section similar to Fig. 2 showing a modification, but partly broken away and with the cover spaced from the body portion of the vault and Fig. 4 is a section similar to Fig. 3 on a still larger scale through a corner showing the cover in place.

The body portion of the vault comprises an inner box I of concrete, which may be reinforced, as indicated at 2, and an outer box 3 of concrete, which may be reinforced, as indicated at 4. A layer 5 of water-proof material is interposed between the boxes I and 2. This waterproofing inaterial should be of such a character that it is adhesive and does not become brittle, but stays plastic. Bituminous material, such as asphalt, or residues resulting from distilling petroleum oils or 'coal tar products are suitable for this purpose.

In installing the water-proof layer 5 between the boxes, the concrete box I may be made in forms in the usual way and permitted to harden. The forms are removed, the layer 5 of Waterproofing material is applied in any convenient way, as by a brush or spraying, for example. Or the bituminous material may be applied by setting up molds of somewhat larger size around this box I and pouring hot bituminous material into the spaces and permitting it to cool and harden. After the bituminous layer 5 has been applied, forms for concrete are put in .place spaced from the layer 5 and the concrete to form the box 2 is poured in and permitted to harden. The layer 5 of bituminous material is preferably 1A; to 1A of an inch thick, and this material is of such a character or consistency that it does not become brittle but remains pliable, so that even if the concrete cracks this bituminous layer remains intact.

The cover for the vault comprises a lower section I of concrete, which is preferably reinforced, as indicated at 8. This section l is also preferably 5 provided with transverse metal bars 9 which pass along near the lower surface of the section l and have their ends bent upwardly, as indicated at I0, so that the lower surfaces of the ends I0 are flush with the corresponding portions of the lower surlo faces at opposite edges of the section 1. The section I has the lower surface inwardly of its edges projecting downwardly, as indicated at I I, so that this portion extends slightly into the vault when the cover is in place. 15

'I'he cover also comprises a layer of waterproofing material I2 that may be of the same sort of material as the layer 5.l 'I'he layer I2 extends all over the top side of the section l and along all four edges and is preferably of the same thick- 20 ness as the layer 5. 'I'he width and length of the section l of the cover are the same as the outside length and width of the box I so that the exposed edges of the layers 5 and I2 come into contact with each other all the way around when the 25 cover is put in place. Since the material forming the layers 5 and I2 is plastic and sticky or adherent, the contacting edges of these layers adhere or flow together and make a water-proof joint when the cover is put in place. 30

The cover also comprises a. section I3 of concrete that is preferably reinforced, as indicated at I4. The section I3 extends over the top side and along` the edges of the layer I2, thus -providing a fiange I5 around all four sides. The cover may 35 be made in a. manner similar t'o the Way the body p ortion of the vault is made as described above. A metallic ring I6 extends all the way around the outer edge of the flange I5. The flange I5 is preferably of the same thickness as the walls'of the box 3 and the lower edge of the ring I6 extends below the lower edge of the ange I5 so that this ring I6 overlaps the outer upper sides and ends of the box 3 when the cover is in place.

When the cover is in place the ends of the metal bars 9 rest upon the upper edges of the side walls of the box I and avoid the danger of the extending portion II of the concrete falling into the vault.

In the modication shown in Figs. 3 vand 4 a layer of water-proofing material I8, preferably of the same material as the layers 5 and I2, is poured into the groove between the inner surface of the ring I6 and the sloping edges of the extension II. 'I'his is done while the material is hot 55 and the cover is upside down. 'I'he water-proofing material I8 is permitted to cool and set. In this modification a V-shaped groove I9 is left above the exposed edges of the layer 5 of waterproofing material and when the cover is put in place some of the excess material in the layer I8 of water-proofing material flows into the groove I 9 and fills it and becomes sealed with the upper edges of the layer 5, as shown in Fig. 4.

The water-proofing material used in this invention preferably has sufiicient adherence and strength so that when installed as described above the portions on opposite sides of this waterproofing material are held together with suflicient strength or firmness to avoidthe danger of the same becoming separated even when no direct attachment is provided between these parts except this water-proofing material.

I claim:

1. In a burial vault, an inner box of concrete, an outer box of concrete spaced therefrom, a layer of bituminous material in the space between said boxes, and a removable cover for said vault having a thin layer of bitumin extending through the body portion of said cover with downwardly extending narrow edges terminating in flattened portions which contact with the edges of said first 'named layer of bituminous material.

2. In a burial vault, an inner box of concrete, an outer box of concrete spaced therefrom, a layer of bituminous material in the space between said boxes, and a. removable cover for said vault, comprising two layers of concrete with a, layer oi bitumin between them, the edges of said layers of bituminous material being adapted to contact when said cover is in place, the edges of the bituminous material in the cover being spread out laterally.

3. In a burial vault, an inner box of concrete, an outer box of concrete spaced therefrom, a layer of bituminous material in the space between said boxes, and a removable cover for said vault, comprising two layers of concrete with a layerof bitumin between them, the edges of said layers of bituminous material being adapted to contact when said cover is in place, the edges of the bituminous material in the cover being spread out laterally and the edges of the bituminous material in said vault being in a groove.
