a Claim. (Cl. lit-7) This invention relates to that class of self-sealing ,vaults or receptacles comprising a box body, and a cover member, one of said members having a marsinal tongue, and the other of said mem l bers having a grooved marginal portion adapted to admit and engagesuch tongue, and to contain a filler of plastic material, or materials heated and introduced into 'the groove in a liquid and adhesive condition, and having a skin or covering 10 spread over or integral with the illler material, and the outer suriace of which covering when dried in relatively harder than the filler material within the groove and over the surface of which such covering is adapted to extend so as to tend I to or temporarily hold the adhesive filler material in place within-the groove, and until suit-' ably conditioned by cooling .and drying out to permit the spreading thereof between the grooved margin of the box cover and the tongue of the box body or receptacle upon the application of pressure incident to the entry oi the tongue'into the'groove of the cover upon amembly and due to the weight of the cover.

, The principal object of the invention is to pro- 25 vide a simple, economical and eillcient self-sealing vault or receptacle comprising a box body member having a tongue in its upper margin, and a cover member having a groove adapted to admit such-tongue, and adapted to contain a illler, and

80 to be hermetically sealed by the spreading of such filler between the margins; the tongue being formed on the box body so that a minimum oi ilatsurfaces will be formed upon which pebbles,

v dirt and other ior'eign matter might collect to as interfere with the proper sealing of the vault and materials may collect.

A further object of the invention is to provide such a device in which abutting horizontal sur- 40 faces are reduced to a'minimum or in which the contour of some of the normally abutting surface is interrupted or varied so that expanding or gradually widening openings will be formed between the cover and body adjacent the tongue 45 upon the assembly of the cover, into which some of the sealing material may be discharged or may ilow to. produce a wash over such remaining relatively flat-surfaces as may be required to provide proper limiting stops, for removing obstructing 50 materials such as may collect thereon and to provide a suitable discharge channel for such mate-' rials.

Other and further objects of the invention will appear from the following description and claims. as and from an inspection oi' the accompanying drawing, which is made a part of this specification.

The invention consists in the features, combinations, and details of -const ruction herein described and claimed.

In the accompanying drawing:--

Figure 1 is a view in perspective of a vault comprising a box body and cover formed of concrete, or equivalent material, showing said cover' and box body in transverse vertical section and sepa- 10 rated, as they would appear before placing the cover upon and in position to cover and close the box body, and before causing the normally plastic filler material to spread and hermetically seal the tongued and. grooved margins of the cover and box body;

' Fig. 2 is an enlarged detail view in vertical section showing the marginal portions, including the grooved'bottom margin,; and tongue and top margin of the cover and box body respectively, as they would appear before placing the cover in position upon the box' body,"

Fig. 3 is a similar view in detail, in vertical section, of the parts shown in Fig. 2, as they would appear with the cover in place upon and in position to close the box body, and with the normally plastic filler material spread between and acting to hermetically seal the united margins of the cover and box body:

Fig. 4 is an enlarged detail view in vertical section showing the grooved bottom margin of the cover provided with a illler of asphaltum spread into and in direct adhesive contact with the walls of the groove, and with the outer surface of the v filler material sumciently hardened by cooling and 3i; to eliminate recesses or pockets in which such I drying, to render the illler the groove; and' Fig. 5 is a similar view'of a modification showself-sustaining within lng means for covering the normally plastic filler material within the groove. I 40 In constructing a vault, or receptacle, in accordance withmy invention and improvements, I provide a boxbody or main vault body member i, comprising side walls I, end walls 3, and bottom 4, and a vault cover I.

The vault or box body is formed of or comprises by preference, concrete, containing sand or hydraulic Portland cement intermixed in suitable-proportions, and formed or molded into the desired shape and dimensions while in a plastic 50 condition. and then" allowed to set and dry and harden. f

The cover member I comp ses a top wall or main cover portion I, which is, by preference, arched, and provided with grooved bottom side It and end margins or upright walls 1 which extend entirely around the bottom or rim of the cover.

The bottom side marginal portions or side walls of the'cover are in parallel relation to and adapted to be secured inabutting engagement with the top margins of the side walls 2 of the box body; and the bottom end walls, or bottom end margins and upright end wall portions of the cover are in parallel relation to and adapted to be secured in abutting engagement with the upper margins of the limit stop portions of the corresponding upright end walls 1 of the box body.

Zlihe cover member 5 is provided with a bottom marginal groove 1, which is, by preference, substantially in the form of an inverted V, in crosssection and extends entirely around the bottom margin or rim of the cover, or, in other words,

along the bottom edge of the upright side and end wallsor bottom'marginal portions 1 of the to extend into and ininterlapping engagement with the bottom groove 8 in the bottom margin of the cover.

The bottom marginal groove l in the cover is, by preference, tapered, or approximately V- shaped in cross-section, as a ready suggested, and is located between inner and outer marginal wall portions III and H; and the endless upwardly projecting marginal tongue 9 on the upper margin or rim of the box body member is also, by preference, similarly tapered, and somewhat wider at its base than at its upper edge, and adapted to flt within the groove snugly, and sumciently close to thewalls of the groove to hold the cover accurately in proper fitting engagement with the box body, but with sufflcient space between the tongue and the adjacent walls of the groove to admit and, permit the proper spreading of suitable filler and sealing material between the tongue and groove.

A quantity of suitable filler and sealing material l2, which, by preference, consists of or comprises asphaltum, or a suitable composition containing asphaltum or equivalent water-proof sealing material, is introduced into the marginal groove 8 in the cover, while said flller or sealing material is in a liquid adhesive condition, and adapted to adhere tightly to the concrete which forms" the walls of the groove, as well as to the tongue 8 on the top margin of the box body,- when said tongue is introduced into the groove,

so as to form a strong water-proof sealed connection between the grooved marginal portion or rim of the cover, and the tongue and top margin or rim of the box body, when the cover is placed upon and in position to close the latter.

For this purpose, I prefer to employ asphalt, or a bituminous compound or composition containin asphalt, which is introduced into the open bottcmmarginal groove or slot I in the bottom rim or margin of the cover, in a heated condition.

and while sufliciently liquid to tightly adhere to theconcretewallsofthe slotorgroove. A sumcient quantity of this bituminous filler and sealing material is thus introduced into the groove I while the cover i is inverted, to partially, and. by preference, almost. entirely flll the groove.

and the upwardly projecting flange or or may consist of hydraulic cement, or composition containing bituminous cementitious material or asphalt, or other suitable adhesive material spread upon and in adhesive contact with the inner surfaces of the inner flange Iliandouter flange l I which form the opposite side walls of the groove or recess 8, and the depending marginal rim or recessed depending marginal flange of the cover member. The flller ii of bituminousor asphaltic material in.a liquid condition maythen be introduced into the recess or groove 8, and after cooling dries on the external surface to formla relatively hard skin I! covering the inclo'sedmore plastic material. An ideal consistency of; the plastic material is such that it will be plastic only under pressure or when pressure is applied and when heated sothat it may be applied after,

being heated to a liquid state and so that after cooling it will flow only under pressure due to the weight of the cover upon assembly thereof to the box.

I have found in practice, however, that, by pro viding a bituminous or asphaltic material or com-' position I! of suitable normally plastic adhesive consistency, and introducing it into the groove 8 while warm and in the manner already described,

but without first applying a coating ll of adhesive material to the concrete wallsof the groove, and then allowing the filler or bituminous composition I! to dry and harden at its outer exposed surface, so as to 'form an outer coating or covering l5 which is integral with the filler l2 thus formed, the filler I! with its integral outer or bottom exposed relatively strong and hardened, but sufllciently fragile coating or skin covering ii in adhesive contact with the walls of said groove, is adapted to sustain itself within the groove even when relatively soft filling ma-' t'erial is used and when the cover- 5 is in upright position, and that the outer integral skin or covering l5, thus formed, is adapted to be automatically broken by the introduction of the tongue 9, and will permit the flller l2 to automatically spread and seal the connection between the cover and box body as already described. (See Fig. 4.)

In Fig. 5 isshown a grooved bottom wall or rim 1 of a cover 5, containing a flller of bituminous or asphaltic material I2 in a normally plastic adhesive condition, as last-above described in connection with Fig. 4, but with a modifled form of covering it, of paper, or other suitable flbrous or similar sheet material, covering the outer surface of the filler i2 and adhesively secured in engagement with the walls of the groove,

the device shown in Figs. 1, 2

said covering of sheet material I, beingsufllcient-- lystrong to retain the flller within and in adhesive engagement with the walls of the groove, and sufllciently fragile to be. automatically broken, and to permit'the spreading of the flller and sealing material I! in adhesive hermetically sealed engagement with the recessed and flangedmarginal portion of the cover and the flanged upper rim of the box body when the cover is in place,

and the vault is closed. 7 Y

From the foregoing it will be readily understoodthat by having the bottom recess or groove 8 and the plastic material in the flanged cover, tonsue I some on the upper margin ori 'rim of the box-body, the

normally plastic adhesive material or cement contained in said groove or recess will be shielded and protected when the cover is off, and also during the operation of lowering and placing the cover upon and in position to close the vault. Since the recess opens downwardly no traps or pockets will be formedin which pebbles and foreign particles of material such as may interfere with the proper; sealing of the vault can collect.

To pron 'le limiting stops for limiting the downward movement of the cover the wall 2 of the box is thicker tha. the base of the tongue so that substantially horizontal surface portions II are formed at both sides of the tongue, either one or both of which may function as a limiting stop and in accordance with my invention the area of one surface portion I1 is reduced at least about the outside of the tongue 9 to the minimum required for stops and so that the area upon which pebbles and foreign materials may collect is reduced to a minimum. This is accomplished by varying the contour of the surface I! interruptedly or by chamfering orbeveling the outer margin of the top rim of the box-body, so as to provide an upper marginal surface portion or series of beveled mar ginal surface portions I8 which extend downward and outward at an incline outside of the flange 9 and from the base of said flange to the outer face of the upright wall of the box-body beneath the outer flange ll of the cover on all sides of the cover. And marginal shoulders l9 are formed on and integral with the upper beveled margin or rim of the box-body. Said shoulders project outward from the upper extremity of the beveled surface portions I8 and beneath the outer depending flange ll of the cover, for limiting the downward movement of the cover relatively to the box-body, particularly during the operation of lowering the cover into position to close the vault.

Any foreign subst'ances which may fall upon the upper flanged rim of the box-body will thus be thrown oil or permitted to escape from between the marginal flange of the cover and the rim of the box-body or vaultv In operation, the cover, having the bottom marginal cement-containing groove normally open downward on the under side of the cover, is

- placed over the box-body member. and its contents, with said bottom cement-containing groove of the cover in position to receive the upwardly projecting marginal tongue or flange on the upper rim of the box-body within said groove, and upon the entry of the tongue 9 into the groove and the application of the weight of the cover the plastic sealing material is squeezed from the groove and molded about the tongue 8- due to the applied weight of the cover and until the limit stops formed of the surface I! prevent further downward movement of the cover at which time the tongue and groove portions of the box and the cover are separated only by a thin fllm of the sealing material which is intimately engaged with the surfaces of both and forms a water proof seal.

As above mentioned the beveled marginal portions II of the surface I! cooperate with the adlodged from obstructing positions or eliminated.

' I claim:

1. In a vault, the combination of a box-body, a

cover having a bottom recess on its under side adapted to contain cement for securing the cover in hermetically sealed engagement with the boxbody, a depending marginal flange on said cover and forming an outer side wall of said recess, and

an upwardly projecting marginal flange on the upper rim of the box-body and adapted to extend into said recess and inside of and in lapped relation to the depending marginal flange on the cover, said box-body having a beveled marginal surface portion extending downward and outward at an incline beneath said depending marginal flange on said cover and adapted to permit the escape oi foreign substances from between the margins of the cover and box-body. 2. In a vault, the combination of a cover having aibottom recess on its under side adapted to contain cement for securing the cover in hermeti cally sealed engagement with the box-body, a depending marginal flange on' said cover and forming side walls of said recess, a box-body having an upwardly projecting marginal flange adapted to extend into said recess and inside of and in lapped relation to said depending marginal flange on said cover, said box-body having a beveled upper marginal surface portion extending downward and outward at an incline beneath said marginal flange on said cover, and marginal vshoulders on the rim of the box-body and projecting beneath the bottom margin of said depending marginal flange on said cover, for limiting the downward movement or the cover relatively to the top margin of the box-body.

3. In a vault, the combination of a box-body, a cover having a bottom recess on its under side adapted to contain cement for securing the cover in hermetically sealed engagement'with the boxbody, a depending marginal flange on said cover and forming an outer side wall of said recess, and an upwardly projecting marginal flange on the upper rim of the box-body and adapted to extend into said recess and inside of and in lapped relation, to the depending marginal flange on the.
