'2 Claims.

This invention relates to a concrete vault used for burial purposes and one object of the invention is to provide a vault which will be formed of set' concrete or the like and have a body and a cover so constructed that they will be very strong and durable and not liable to easily crack.

-It is another object of the invention to so form the body portion and the cover of the vault that, when the cover is set in place upon walls of the body, a very good joint will be formed between contacting edge faces of the cover and the walls of the body. 7

It is another object of the inventionto provide improved apparatus for making the vault, this apparatus being in the form of a mold of such construction that the body portion and the cover can be formed in the same mold and thus fit together accurately when removed from the mold. Another object of the invention is to provide a 20 mold which'may be formed of wood and will be very strong and durable and capable of withstanding hardusage.

Another object of the invention is to provide the mold with inner sections formed of sheet met- 25 al and of such construction that, while the vault may be molded about the inner section, the sections can be very easily removed after the concrete has set. i

It is another object of the invention to so form 30 the inner mold for the cover that it will serve to separate the cover from the body portion of the vault during molding thereof and in addition serveto provide the contacting edge faces of the cover and the walls of the vault with interfitting 35. portions to form a tight joint between the cover and the walls of the vault.

The invention is illustrated in the accompanying drawings,-wherein Figure 1 is a top plan view of the mold for form- 40 ing the vault, the inner sheet metal sections of the mold being shown in section,

I Figure 2 is a vertical sectional view taken longitudinally through the mold along the line 2--2 of Figure 1,

45 Figure '3 is a perspective view of one of the sections forming the sheetmetal inner form for the mold,

Figure 4 is a sectional view taken transversely through the mold along the line 4-4 of Figure 2, 50 and 1 V Figure is a perspective view of approximately one-half the form and its cover.

.The vaultformed in accordance with this invention has a body I formed of concrete or simifililar material and a cover 2 which is also formed of concrete, and referring to Figure 5, it will be seen that the body of the vault has a bottom 3 from marginal portions of which extend side Walls 4 and end walls 5 which are shown in Figure 2. The bottom and walls of the body and also the top 5 should be reinforced to prevent cracking, and in order to do so, there have been provided wire mesh reinforcements 6 and 'I which are embedded in the top and in the bottom and walls of the body during molding thereof. Upper edge faces of the walls of the body are formed with longitudinally extending grooves 8 and marginal edge faces of the cover are formed with depending longitudinally extending ribs 9 which fit into the grooves 8 and'not only serve to prevent the cover from shifting longitudinally or transversely of the body out of its proper position thereon but also cause tight joints to be formed between the cover and the walls of the body when the cover is cemented into place. A suitable number of sup- 0 porting strips l0 may be placed in the body upon the bottom thereof so that, when a cofiin is placed in the vault, it will be held spaced slightly above the bottom of the vault. These cross strips may be merely set into the body upon the bottom thereof or secured in place upon the bottom in any desired manner. Eye bolts H which have their lower ends secured through reinforcing mesh 1 of the cover extend upwardly from the cover in order that the cover may be lifted with suitable hoisting mechanism and the body portion of the vault may be formed at its ends with recesses or notches I2 in which grapples of a hoist may be engaged when lifting the vault.

This concrete vault is formed by a molding op eration, and referring to Figures 1, 2 and 4, it will be seen that the mold in which the vault is formedhas a flat bottom I3 which may be formed of wood or any other desired material having sufficient strength and thickness to prevent flexing and consequent distortion of the bottom. Side walls 14 extend longitudinally of the bottom in spaced relationto side edges thereof and are reinforced by uprights 15 which extend the full height of the side walls and are secured thereto. When theside walls are in place upon the bottom, lower end portions of the outer edge faces of the uprights having abutting engagement with inner side edge faces of abutment strips l5 secured along the side edge portions of the bottom, as shown in Figures 1 and 4. Therefore, outward movement of the side walls toward side edges of the bottom will be prevented and bulging of the mold cannot occur. Emd walls I! of the mold are also provided with uprights l8 corresponding to the uprights l5 and having their lower ends engage inner edge faces of strips l9 which correspond to the strips l6 and are secured upon the bottom along end edges thereof. The uprights 29 adjacent ends of the side walls are closer to each other than the uprights I5 and between these uprights 20 are located uprights 2| which are disposed transversely of the uprights 20 and fit snugly between the same with their outer side faces flush with outer edge faces of the uprights 26. These uprights 20 and 2| cooperate with each other to provide the side walls with corner posts, and upon referring to Figure 1, it will be seen that the uprights I8 and the uprights 20 of the corner posts are formed with openings through which to receive metal rods 22 which serve as tie rods, means being provided at one end with a head and having its other end portion threaded to receive a securing nut 23. When the securing nuts are tightened, end portions of the side walls will be held firmly in abutting engagement with side edge. faces of the end Walls and certain of the uprights l6 and the walls of the moldwill thus be firmly held in proper cooperative relation with each other to form a rectangue lar mold. By removing the tie rods the side and end walls will be released and piled upon the bottom. 'It will thus be seen that the mold is of a knock-down construction. Blocks 24 are carriedby the end walls to form the grapple-receiving recesses I 2, at ends of the body portion of the vault and corner strips 25 may be employed to form tight joints between the side walls and meeting side edge faces of the end walls. I

After the side and end walls have been set up.

upon the bottom to form the body of the mold, concreteis poured into the mold to form the bottom of the vault. When approximately one-half the quantity of concrete necessary has been distributed over the bottom of the mold, the wire mesh. reinforcements for the bottomand walls of the vault will be set in place and the remainder of the concrete for forming the bottom of the vault'poured into the mold and evenly distributed therein so that the bottom of the vault will be of the same thickness throughout its entire area. The inner form for the mold is then set in place.

This inner form, whichis indicated in general by the numeral 26, is formed of strong sheet metal and consists of companion sections 21. Four of the companion sections constitute the inner form andeach is constructed as shown in Figure 3. Referring to this figure, it will be seen that each section of the inner form has a bottom 28 and side and

end walls

29 and 30 which are preferably formed integral with the bottom and each, other but may have their abutting side edges welded or otherwise firmly secured to each other. Upper marginal portions of the side and end walls are bent inwardly to form a flange 3| which extends along the side and end walls and since the flange has a'folded under portion 32, it will have a rounded edge. It will thus be seen that the section may be easily grasped by the flange and lifted without danger of cutting a persons hand, and in addition the flange will be reinforced and prevented from being easily broken or bent downwardly out 10f its proper position. The three side and end edges of the bottom Z8 are so out that,

when the sections are assembled to form the inner metal form for the mold, slots or spaces will be provided between confronting edges of the sections, as shown clearly in Figures 2 and 4, and,

thus permitthe'. sections to be shifted andeas'ily removed afterayaulthas been formed andthe accidentally shifting out of their proper position.

In order to secure the form sections 21 in cooperating relation to each other, there have been "provided strips 35 which are secured against the side and end walls of the sections. These strips are formed of angle metal in order to provide flanges projecting from inner faces of the wall and certain of the strips are so applied to the walls that their wall-engaging portions extend downwardly while others have their wall-engaging portions extending upwardly from their outstanding portions. It will thus be seen that when the sections are assembled the strips 35 which are of such length that they project beyond ends of the walls to which they are attached and overlap the cooperating strips 35 of an adjoining mold section may have their outstanding flanges rest fiat upon the outstanding flanges of the strips which they overlap. Slots 35 which are to be. dis: posed in registering relation to each other are formed through the outstanding flanges of the.

strips 35 and through these alined slots are passed tapered wedges which, when driven into place, will firmly hold the sections of the innerform in cooperating relation to each other. It will thus be seen that after the concrete to form the bottomv of the Vault has been poured into the mold and evenly distributed the sections of the inner form can be assembled and the completed inner form then set in place within the mold or the sections 21 may be individually lowered into the mold and then secured to each other to form the completed inner form. With the inner form in place concrete may then be poured into-the space between walls of the inner form and walls of the mold to form the side and end walls of the vault. The,

ally disposed, as shown in Figure 2. Marginal portions of the top form are flat to provide a flange 40 extending along sides andends of the form and intermediate the width of the flange the material thereof is stamped downwardly to provide adepending rib or trough 4!. By forming the flange withthe combined rib and trough 4! the groove 8 will be formed in the upper edge facesof the side and end walls of the body portion of the vault when the form is set in place.

Concrete or the like can then be poured onto the form and since a portion of this concrete will enter the trough the depending rib 9 along sides and ends of the cover will be formed. It shouldalso; benoted that since the combined rib and trough form both the grooves} and the ribs 9 the ribs 9 will fit properly intothe grooves B when;-

the ;cover isapplied and a tight joint formed when the ribs are cementedintothe grooves. A bolt 42 is engaged through an opening formed intermediate the length and width of the form 38 in order that this form may be easilylifted and set into'place, the opening through which the boltextends being of such diameter that after the form-is in place the bolt may drop downwardly to the position shown in Figures 2 and 4 when released. There have also been provided handles or straps 43 which extendtransversely of the form in spaced relation to each other longitudinally thereof. These handles or straps are provided so that, when the form is in an inverted position, it may be lifted. After approximately one-half the concrete required to form the cover has been deposited upon the form and evenly distributed, the wire mesh reinforcements are applied and the remainder of the concrete then poured over the reinforcement and evenly distributed; The eye bolts H are secured through the reinforcement, as shown in Figure 2, and projects upwardly from the finished cover so that grapples may be engaged in the eye bolt and the cover lifted when it is to be applied to the body portion of the vault. Attention is called to the fact that the end walls ll of the mold extend upwardly beyond the side walls l4 thereof, as clearly shown in Figure 4, so that during forming of the cover the concrete may have abutting -engagement with the projecting upper end portions of the end walls. The upper surface of the cover conforms to the transverse outline of the form 38, and when it is troweled to shape it will have side portions of its upper surface curved downwardly. The ends of the cover will have flat faces due to contact of the concrete with the end walls of the mold but if so desired these end portions may be shaped to conform to the curvature of the side portions of the cover. After the concrete forming the cover has fully set, the

cover can be lifted out of the mold and set upon thefloor in an inverted position. The grapples of the hoisting mechanism used for lifting the cover from the mold can then be engaged with the straps or handles 43 and upward pull exerted to detach the form from the cover. It will thus be seen that the form can be again used. After the cover has been removed, it is merely necessary to remove the cross bars and the wedges to release the sections 31 and the sections can then be easily shifted away from the inner surfaces of the side and end walls of the body of the vault and removed. The tie rods 22 can then be removed and the side and end walls of the mold detached from the bottom, after which the body of the vault can be lifted by a suitable hoist The mold can then be reassembled and again used as previously set forth.
