V Referring to' Fig.;1,,-Vreterence character 1 gen-- erally designates a metal vault formed of two, sides 2 and two ends 3 with a top portion 4 of any desired form, but exemplified as beingroof-shaped with a ridge 5 in order to shed water in case the'vault is exposed-t0 rains-The housing or vault l= is adapted to be fitted over a metal plate 6 which may be provided with upstanding flangesor locating the interior-"sur- 40. spaces before receiving the casket; and then desired, ofthin-walled concrete, reinforced and suitablytreated onthe inside and outside-with tar or other water-impermeable substances.-

When the vault is 'made out of metal and before the porcelain is-applied; the'housingds conveniently pressed=-out of sheet metal by a deepdrawing press :inorder to eliminate-any joints at the ends. However,- it is to beunderstood; particularly whenthe casket is to -be inserted into theend of the vault, one orv both end walls 3'may beformed separately fromthe side walls -2 and the root; these end walls being-.1 pro+ videdwith flanged edges which fitsnuglylwith in the mainportion of thevaultand can'be eitherwelded or silversoldered at'the flanges in order to form an integral structure. The handles "i are detachably affixed to the vault in any suitable and well known manner, and mainly used for ornamentation purposes.

When interring a casket the usual practice is to leave the vault above ground and the upper portion thereof removed from the plate 6 for receiving the casket. At the appropriate time the main portion of the vault is placed on the plate 6, using the handles 1 for lifting purposes, and the metal vault is then affixed as by screws (not shown in Fig. 1) to the plate 6. Thereafter, and in accordance with one feature of my invention, silver-solder is poured in the space between the walls and the outer flange of the plate 6 and if desired a layer of tar applied in order to provide a perfect hermetic seal at the joint between the lower edge of the walls, 2,

3 and the plate 6.

It has been found that when the ordinary vaults made of metal are employed for encasing a casket, great deal of moisture collects within the vault over a period of time and this moisture promotes the growth of fungi and similar plants, also tending to cause deterioration of the metal of the vault and the joints between the vault housing and the bottom plate.

In accordance with another feature of my invention, I provide a highly evacuated space between the casket and the vault walls and if the casket itself is not hermetically sealed, this vacuum extends into the casket. For this purpose an opening 8 is provided in the top of the vault (Fig. 6) and this opening receives a metal plug 9, the latter being welded at the edge H1 in order to assure a hermetic joint. The plug 9 is pro vided with a pair of countersunk holes ll, 12 and the latter communicates with the interior of the vault through a small opening l3. The hole or recess II is provided with threads in order to receive a screw plug [4 and the lower hole I2 is provided with a plug of rubber l5 which has a central opening in line with the aperture I3.

The upper end of the plug I5 is given a conical reentrant shape as indicated at [6 for receiving a metal ball H of hardened steel which normally fits over the central opening in the plug and prevents communication to or from the interior of the vault.

After the casket has been placed on the plate 6 and the top portion of the vault I has been placed over the casket and sealed to the plate in the manner explained hereinbefore, or in any other suitable manner, the screw plug H is removed and the end nipple of a suction pipe l3 (illustrated in Fig. 2 in connection with the modified form of vault) is screwed to the threads vacated by the plug.

The pipe or line [3 passes to the suction side of a vacuum pum IQ, of any suitable and well known type, which is operated by an electric motor 20. A combined pressure-suction gauge 2| may be contained in the line [8. Thus as the pump continues to operate, a relatively high vacuum is produced within the vault and if there are any openings present in the casket the air is also evacuated from the casket interior. But the main object of the invention is to evacuate the space surrounding the casket since this space is usually of much greater content than that contained in the casket and for that reason can offer far more deteriorating effects than the air or gas within the casket. The vacuum should be carried as high as possible when using commercially available high vacuum pumps and the operation of the latter and the vacuum conditions within the vault can be read from the gauge 2|.

When all of the remnant air, gas and moisture have been removed from the vault interior, the pipe I8 is disconnected and it will be found that the ball II will drop down into the conical hole to shut off all further communication with the vault interior. In other words, the ball I! serves as a check valve and, due to the rubber seat 15, forms a perfect hermetic seal. The plug I4 can then be re-inserted and after the handles 1 have been removed, the vault is ready to be placed either in the ground or in a mausoleum.

In case the vault is made of concrete, the interior and exterior surfaces should be tarred or otherwise rendered impermeable to air and moisture and a suitable provision can be made for inserting the metal plug 9 for effecting the evacuation of the vault interior.

It has been found that when the interior of the vault, as described, is sufficiently highly evacuated, any gases or moisture given off at the casket are so highly diffused throughout the vault interior that little or no deteriorating effect is noticeable, since the high vacuum provides a protective media and many of the causes for deterioration of the casket and vault from within have been eliminated. Besides, the absence of the normal air content serves to a certain degree to thermally insulate the casket and contents which additionally reduces the ravages of a soil which may be temporarily above normal temperature. The process of evacuating the vault interior is not expensive since, obviously, the vacuum pump can be carried on a truck and moved from one graveside to another with maximum facility and lack of attention after the connections have been made.

My invention is not limited to a single-walled vault but can be readily applied to a double or other multi-walled unit as shown in Figs. 2, 3, 4, 5 and '7. In Fig. 5 there are two metal plugs 22, 23 employed, these plugs being made similar to the plug 9 shown and described in connection with Fig. 6, except that one plug 22 terminates in the space between the walls 24, 25 of the vault, and the other plug 23 terminates at the interior of the vault indicated by the opening 26. When the screw plugs 21, 28 have been removed from the respective evacuating plugs 22, 23, twin suction pipes (not shown) may be taken to the vacuum pump l9 or, if desired, the interior of the wall 25 can be first evacuated and then later the space between the walls, by removing and reinserting the proper screw plugs 28, 21. A single conduit l3 may also be employed with a twin or forked suction nipple structure, in which case a single gauge 2| can determine the vacuum conditions throughout the interior of the vault.

The walls of the double-walled vault can be separated the requisite distance apart by means of longitudinal angle irons 29 (Fig. 3) and the plate on which the double-walled vault is mounted may also comprise a two-walled structure indicated at 30, separated from one another by the angle irons 3|. Openings 32 may be provided in the upper wall of the plate 30 in order to evacuate the air between the two walls of the double bottom plate.

Instead of evacuating the space immediately surrounding the casket by means of the plug 23 (Fig. 5) which withdraws the air from the top of the vault, it may be desirable to evacuate from the bottom of the vault, particularly in case the plate 30 is formed with a double shell. This can plate.

be accomplished by providing a plug 33 which extends through the double wall of the vault at the top and is provided with the screw plug 34 as in the case of the plug shown in Fig. 6. But the opening 35 at the bottom of the plug communicates through a copper conduit 36 with a valve 31 secured to the side of the inner wall of the vault at the bottom. This valve comprises a housing containing the rubber sealing plug 38 and the ball 39. An opening 40 passes through the rubber plug and through the bottom of the valve to communicate with the interior of the vault. Thus when the screw plug 34 is removed and a pump connected thereto, the interior of the vault, as well as the interior of the doublewalled bottom plate, is evacuated.

It will be understood that if desired a plug 22 (Fig. 5) may be employed to evacuate the interwall space, as was explained in connection with that figure, although in general, the manufacturer of the double-walled vault would normally evacuate the inter-wall space at the factory and might also evacuate the space between the two walls of the bottom member 38. In case the inter-wall space is evacuated before the vault is delivered, a plate H is welded to the lower edges of the vault in order to seal the inter-wall space, and this plate can then serve as a securing means to the bottom plate 35 by the use of screws 42 (Fig. 4), or if desired, solely by depositing silversolder 43 in the space between the outer wall of the vault and the flange 45 formed on the bottom It will be understood that when screws 42 are employed, there may be additionally supplied a covering of silver-solder or a tar coating in order to assure a perfectly tight hermetic joint.

The remote position of the valve 31 from the plug 33 offers some advantages over the use of the plug 23 (Fig. 5) at the top, of the vault in that the suction effects of the vacuum pump I9 are carried in a more concentrated form through the conduit 35 to a position near the bottom plate and for that reason is more apt to pick up any moisture collected on the bottom. In order still further to assure the complete disposal of condensed moisture on the bottom plate, conduits 45 may be taken from the opening Ml and terminating at various points throughout the bottom of the vault in order more effectively to pick up moisture as well as to evacuate the lower strata of air. These conduits also serve the additional purpose of strengthening the bottom plate in the longitudinal transverse directions, dependin upon their arrangement, since they can be secured in any suitable manner, as by welding, to the bottom member.

In Fig, 4 there is shown still another optional manner in which the evacuating conduit can be taken out of the vault interior. In this case a vertical pipe extends along one end of the vault and is provided at its upper end with screw threads for receiving a plug Al. The lower end is closed except for an aperture is and this end contains an apertured rubber plug 49 and a steel ball 56. Inasmuch as the pipe M5 runs along one end of the vault, it is out of the way of the casket and obviously, in case the vault is intended for end insertion of the casket, the pipe is positioned at that end which would not normally be disturbed. It will be. understood that as in the case of Fig. 3, a plug 22 may be employed to evacuate the inter-wall space, as was explained in connection with Fig. 5, although if desired, the manufacturer of the vault will already have evacuated this space before the vault is delivered.

' From the foregoing it is evident that I have disclosed a highly evacuated, hermetically sealed vault having one or more walls in which the vacuum extends to the space immediately surrounding the casket, as well as to the inter-wall space. The evacuation process can be performed at the graveside and the high vacuum serves to protect not only the interior of the vault from corrosion, growth fthallophytic plants and other deteriorating effects, but also helps in preserving the casket which may be constituted of wood or metal.

If desired, the vacuum treatment can be given the vault at predetermined times after interment to assure a highly evacuated condition of the interior of the vault, as it would only be necessary to expose the plugs 21, 28 for this purpose.

The invention is not limited to vaults made of metal but can be applied to vaults made of any other material such as plastic, wood or concrete. provided such material is impermeable to gas and moisture or can be made impermeable by suitable coatings and treatments.

It will be understood that various modifications and arrangements in structure could be made without departing from the spirit of my invention and, accordingly, I desire to comprehend such modifications and substitutions of equivalents as may be considered to come within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
