METHOD AND MEANS FOR MOLDIN G VAULT LIDS.

Application filed February 15, 1928. Serial No. 254,521.

The object of this invention isA to provide a novel method and means for molding a vault lid on a vault body.

Burial Vaults of concrete are very heavy and it is necessary that the .lid should not only be the same size, but. that it should accurately fit the upper edges of the walls ofthe vault body.

Now itis a special feature ofV my invention toziirst complete the vault body and provide the upper edgesl ofthe walls thereof with the proper or desired contour, and then employ the completed vault body as a part of the means or mechanism for molding the lid therefor.v

Inv-accordance; with' my invention, form apparatus iswsupported on and attached to the completed vault onto which and. into which apparatus the concrete or other materialof which` the; lidv is to be formed is poured, so that afterthe, lid has set, it will be accurately thesize necessary for the vault.

body. l

My improvedI formy apparatus is designed and constructed to coact with the vault. wallsand the lid being formed ther-comin a manner to provide sealed spaces, which spaces are -preferablydisposed in what I. will term inwardly and outwardly arranged4 positions with 1 respect to an intermediate strip of contact between they lid and the wall edges...

lily invention has other objects and fea tures which will be more fully describedfin .4 connection with the accompanying drawings and which will` be more particularly pointed outin and `by the appended claims.

In the drawings: Fig. l, is a vertical cross sectional view showing a completed vault body; with my improved form mechanism attached thereto and'rillustrating how the lidis formed thereon..

Fig. 2, is a similar view of the lidi shown detached from the vault body.

Fig. 3, is a View of the vault body with a portion of the form mechanism removed therefrom.

Fig. 4;, is a top plan View of a supporting;

form detached from a position of use and showing` the samev onf a reduced scale rfrom that-employed in Fig. 1.

Fig. 5,A is a bottom plan view thereof. Fig. 6, isa top plan view of the. vault body with theformed lid thereon and show ing the manner in which the outer form mechanism is applied;y

Like characters of reference designate similar parts throughout the diferent' iig--r ures of the drawings.

Reference will first be made to the vault body wherein it will be seen that thevsame consists of a bottom wall l, side wallsQ and end walls 3, all of said walls being preferably alike in contour and cross section. This vault body is made of concrete orlike plastic material capable of being molded and any desired form mechanism may be used, as far as my present invention is concerned. It may be pointed out that theupper portions of walls2 are formed ofa greater thickness thanthe lowerportions to afford the necessary 4width of contact with the lid and provide for rsealing areas, hence, all the walls are made thicker at 4, and on the outside of the walls, I provide the same with a flat vertically disposed abutment portion 5, the purpose of which will later appear.y

The upper edges of the walls are also` formed in a novel manner and for a: purpose of not only providing novel innerand outer sealing spaces but also disposing said spaces so that they will shed water outwardly and downwardly. Y

Thus, as clearly shownat the left of Fig.` 3, the upper edge is provided with a prefy erbaly horizontal inner surface 6, which is also a form supporting surface, as` will later appear. An intermediate surface 7, which isa lid contact surface, slopes downwardly and outwardly from surface 6. A` short outer. surface 8, slopes downwardly and outwardly from the intermediate surface 7. I have thus .set forth the essential novel features. of the4 upper edge portions of the vault walls and I will next describe the manner and means whereby this configuration is transferred to complemental portions of the lid, in accurate registry therewith, so that they lid is bound to lit the vault. f

Oneyof the features of my mold mechanism is in the form of a supporting mold structure which consists in part, of va thin and preferably metal shell 9 which may be flat, as shown, at its central portions but which slopes toward its edges, as indicated at l0, thus providing anarched formation transversely and longitudinally of the form.k As a means of stiiiening the sheet form, I secure thereto a plurality of form beams 11, as by means of nails or screws 12, to hold the shell 9 to form. It will be seen from Figs. 4 and 5, that these beams extend transversely of the length of said form and it will be clear that they terminate at or just inside the inner faces of the walls 2. rIhis arched form imparts to the lid, a similar form, which strengthens the same irrespective of any reinforcements that may be employed. I provide the lid supporting form, which as will now be seen, spans the inner walls 2 and 3, with an outwardly exn tending supporting flange 13. This flange 13, is of a width to seat on the inner section 6, and support the form on walls 2 and 3. Further, this flange 13, is of a thickness sutlicient, and preferably only sulicient to form an inner sealing space between the lid and the upper edges, which sealing .space extends completely around said upper edges. As a means of stilfening the beams 11, and also as an alining means, I nail ory otherwise suitably secure strips 1l and 15 as shown, which strips form abutments that engage the inner faces of walls 2 and 3, to center the supporting form on said walls.

I will next describe the outer or surrounding mold means in which the outer edge portions of the lid are formed.

Said outer form includes mold timbers 1G and 17 which are abutted against the faces 5, and secured by suitable clips 18, at the corners. I prefer to employ a sheet iron or like form 19 and 20, which fits over the timbers 16 and 17, as clearly shown in Fig. 1, and which is provided with a depending portion 21 extending inside the timbers and against which the concrete of the lid extends while being` formed. Each form 19 and 20, is in all respects alike in this particular, therefore, and only one need be described in detail. Said form 19 has a space or sealing form extension 22, which extends inwardly slightly above the outer sealing face 8, with which each upper edge is equipped.

Now it will be assumed that the mold mechanism just described is all in place clearly shown in Fig. 1, with the parts already to pour the lid, which I will designate at 23. As a usual expedient, the supporting form will be covered with paper or something of like character to prevent the concrete from adhering thereto, and likewise, the same will be done as regards portions 21 and 22. In the intermediate space 7, between the sealing spaces 6 and 8 a strip of paper 2K1, will be disposed. Now with these preliminaries accomplished, the concrete will be poured on the form structure and suitably manipulated or troweled to the contour shown. Suitable handles 25 may be disposed in a manner to bury their lower bent ends 26, in the concrete, as shown, and as will be obvious to those skilled in this art.

After the lid 23 has set, the form timbers space forming portion 28, and an inter-` mediate litting or supporting portion 29. Now because of form portions 22 and 13, the lid 23 will only actually engage and come into contact with the upper edges of the vault when portions 29 and 7 contact, assuming that the lid is to be lowered from the Fig. 2, position. Thus, part 27 will be in spaced relation to part 6, and part 28, will be in spaced relation to part 8. It will thus be seen that when the outwardly sloping portions 7 and 29, come into contact, the lid 23 will not only be accurately centered on the vault, but the outwardly lateral sealing space will be below the sealing Space formed by 6 and 27, thereby acting to prevent water from entering the vault.

If the vcasket were disposed in the vault as shown in Fig. 3, a quantity of sealing cement would first be disposed in surface 6, and when the lid 23 was lowered intov place,

the inner seal would have been formed.- ,ByV

reason of the thickness of the form portion 22, and the advantageous slope of portion 8, there would be an outer sealing space which the operator would trowel full of cement and there would thus be provided an inner and upwardly disposed sealed joint and an outwardly and lowermost disposed sealed joint, with the intermediate portions 7 and 29, between the two, and in close engagement.

It is believed that my invention will be fully understood from the foregoing de'- scription, and while I have herein-described one specific feature thereof, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim:

1. In a means for molding a concrete or like vault lid, the combination with a finished concrete vault body with upright walls having top edges, a lid supporting mold form mounted on said vault body and spanning the space between said top edges to receive the major portion of the concrete for forming the lid, and mold members outwardly surrounding said vault body for forming the outer edges of the lid.

2. In a means for molding a concrete vault lid, the combination with a set concrete vault body having upstanding walls, and said walls having top edges having a configuration to be complementally formed on the coacting engaging face of the lid, a lid supporting form spanningsaid walls and h aving a forming flange engaging inner portions of said top edges and said supporting form being adapted to receive the eonorete to form the lid, said flange being adapted to form an inner sealing space between said top edge and said lid corresponding to the thickness of said flange, means for forming an outer sealing space between said top edge and said lid, and a nonjuneture strip disposed between said flange and means to pre-- vent setting of the lid to said top edg 3. In a means for molding a concrete vault lid, the combination with a finished concrete vault body for which a lid is to be molded, said body having upstanding walls having upper edges provided with a eonligura'tion to be eomplementally formed on the coacting engaging face of the lid, a lid support-v ing arched form spanning said Walls and having an outwardly extending sealing space forming and supporting flange engaging portions of the upper edges to support said form.

4. In a means for molding a concrete vault lid, the combination with a nished concrete vault body for which the lid is to be formed, said body having upper edge portions adapted vto form a mold for forming eoaeting portions of the lid7 and mold mechanism eoaeting with said body forv molding the remaining portions of the lid.

5. The herein-described method of molding a concrete lid on a vault, which consists, in supporting and eonlining the Conerete of which the lid is to be molded on and about the vault with the latter' in part forming a mold and permitting the lid material to set thereon, and in interposing material to prevent the lid to bond with the vault.

In witness whereof I have hereunto set my hand.
