BURIAL-VAULT OR TOMB.

SPECIFICATION forming part of Letters Patent No. 226,743,- dated April 20, 1880,

Application filed March 21, 1879.

To all whom it may concern Be it known that l, WILLIAM F. GROVES, of Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Burial-Vaults or Tombs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification, in which- Figure l is perspective view of a single tomb hermetically sealed, with the end in crosssection, composed of hydraulic cement and placed under-ground. Fig. 2 is a cross-section of a double tomb under-ground. Fig. 3 is a vertical longitudinal sectional perspectiveview, exhibiting the door in the top provided with packing, also the metallic obstructions and explosives for protecting the tomb. Fig. 4 is an end elevation of a large tomb (underground) provided with a'burglar-proof door which has packing and also explosives. (Shown in dotted lines.)

The object o'f my invention is to construct a tomb that will be impervious to moist-ure, and also burglar-proof, as far as it is possible to make such a structure.

In constructing a tomb, I use hydraulic cement and sand mixed with scrap metal. I i'irst make a box, A, provided with a number of braces, to support the box until the cement sets, and place it in the hole made in the earth B. I then mix hydraulic cement and sand, and place it around the box, forming a wall, C, which I build nearly to the top of the box, and which remains incomplete until the cofn is put in the tomb, when I place a wooden arch, D, on the top of the box the entire length of the tomb, and nish the wall, and on the top of which I commence the arch E. When beginniug the building` of the arch I place as much cement mixed with sand and scrap metal on the top of the wall and slope of the arch as may be desired. I then lay a board, F, on each side, and pack on top of said board suficient earth to hold the cement in place until it sets. I immediately place cement mixed with sand, scrap metal, andexplosives on top of the archmold, and cover it with boards F', and finish the tomb with atop board, F", and then ll in the hole with earth, the same as an ordinary grave. I thus make a hermetically sealed tomb which is impervious to water.

After the walls are formed, and before placing the coffin in the tomb, I remove the braces which were placed there to hold the frame in position until the'cement had set.

When building a tomb with a cement door, G, on the top, as shown at Fig. 3, I place a frame the size of the door on top of the arch, and then complete the arch, as heretofore described. In making the door G, I form it in a separate mold, which is made to fit closely in the doorway, and made air-tight by means of suitable packing material g, and secured to the top of the tomb by a bar or lock, or any suitable fastening.

When building a family tomb under-ground a burglar-proof door is made in the end, as shown at Fig. 4, in the same manner as an ordinary bank -vault door, the rabbets being provided with packing material g, to prevent moisture or water from entering the tomb. Sufficient room may be left in front of the tomb to allow the door to open, and also for a iiight of stairs; so the earth need not be removed whenever the tomb is to be opened.

When the tombI is in the course of construction I place a quantity of scrap metal, H, promiscuously throughout the walls, to retard the efforts of burglars when trying to force au entrance. I also place, in suitable openings throughout the wall, explosive materials, I ,with

fulminate or compounds of nitro-glycerine, so arranged that burglars, when producing any undue concussion on the door or upon any part of the tomb, will cause it to explode and destroy them in their unlawful efforts; or a quanr tity of the ordinary loaded metallic pistol or rie cartridges are mixed with the cement, either in the single grave or tomb, and if any attempts are made to violate the tenement of the dead by working through the hardened stone, sufficiently loud explosions would becaused to alarm the depredators and call assistance, even if the bullets of the cartridges did not seriously wound them.

Having described my invention, I claim the following:
