Lorenz, 2433 N. 111th St., Milwaukee, Wis. 53226 Filed Nov. 5, 1968, Ser. No. 773,382 Int. Cl. E04h 13/00; E06b 5/00 U.S. Cl. 52-136 8 Claims ABSTRACT F THE DISCLOSURE BACKGROUND OF THE INVENTION Field of the invention The present invention pertains to mausoleum crypts and relates to mechanism for supporting and releasably locking slabs of marble or other ornamental material at the front of each crypt.
Description of the prior art Heretofore it has been customary to drill holes in the marble fronts and to bolt the fronts in position on the crypts using ornamental rosettes. Some efforts have been made to provide special fittings for holding the marble fronts in position, but all of these fittings have required either the sawing of slits in the marble or the drilling of some sort of hole in the marble. One type of fixture comprised an L-shaped bracket supported on the crypt floor. This carried a shelf member on which the lower edge of a marble front was adapted to rest. There was a small screw operating in a tapped hole in the shelf which had to be manipulated into a drilled hole in the lower edge of the marble. This took a great deal of time to install and there was always danger of damage to the marble when it is necessary to drill holes therein.
Another type of fitting is shown in Pats. Nos. 2,574,- 938 and 2,853,870. These disclose a fixture which is cast into the concrete walls of the crypt and which has a projecting horizontal shelf with a keyway located adjacent the corners of four marble fronts. The lower edge of two marble fronts were adapted to rest on the shelf, but these lower edges had to have slits sawed therein to receive a key member projecting from the shelf. This type of closure was time-consuming and there was always the danger of damage to the marble front. These prior fixtures all had portions engaging in the small space between the lower edge of one marble front and the upper edge of another marble front and there was the necessity of manipulating connection pieces in this small space.
SUMMARY OF THE INVENTION The present invention provides a crypt closure wherein latching members are adhesively bonded to the inner surfaces of the marble fronts, there being complementary latching members adjustably supported on the front edge of the floor of each crypt which coact with the latching strips near the lower edge of one marble front and also with spring sockets near the upper edge of a marble front therebelow. With this arrangement each marble front can be installed by lowering the marble front into tongue- 3,550,337 Patented Dec. 29, 1970 ACC and-groove engagement with the upper latch portions of the crypt fixtures and then by pressing the upper portion of each front inwardly into yielding engagement with ltlijwer latching portions projecting from a crypt floor therea ove.
A. general object of the invention is to provide completely concealed crypt closure fittings, to provide a crypt closure which eliminates the necessity of drilling, sawing, or other mutilation of the marble fronts, and to provide a construction which greatly facilitates the installation of such marble fronts.
A further object of the invention is to provide crypt fronts which may be readily removed only by parties familiar with the procedure.
A. still further object of the present invention is to provide a crypt closure which is relatively simple in construction, inexpensive to manufacture, and otherwise well adapted for the purposes described.
BRIEF DESCRIPTION OF THE DRAWING In the accompanying drawing, in which the same refererice numerals designate the same parts in all of the views:
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring more particularly to the drawing, the numeral 10 designates a series of adjacent crypts, each of which is adapted to be closed by a rectangular front in the form of a slab 11. While these fronts are usually marble, they may be of other stone material orveven of plastic, 'or metal. Each crypt includes a concrete floor 12, which floor also forms the roof of a crypt therebelow. Each crypt also includes concrete sides 13.
Referring now to FIG. 2, the top surface of the concrete oor 12 of each crypt is recessed inwardly from the forward edge as at 14, there preferably being two such recesses for each crypt floor. Fitted in each recess is a support in the form of an angle member 15 having a depending front ange 16 which fits against the forward edge of the crypt floor. The top of each angle member 15 has an elongated slot 17, and a bolt 18, equipped with a nut 19, is employed to bolt each angle member in the position shown in FIG. 2. The slot 17 makes it possible to adjust the angle member in and out slightly. A crypt fixture 20 is in the form of a plate which is adjustably secured by bolts 21 to the depending flange 16 of each angle member 15. The latter extend through upright slots 22 in the plate 20 so that the plate is adjustable in a vertical direction with respect to the angle member support 15. Each plate has an upper latch in the form of a shelf 23 projecting forwardly from its upper edge, the forward edge of the shelf having an upwardly projecting tongue 24. Projecting from the lower forward face of `each plate 20, near the lower edge thereof, is a horizontal latching tongue 25 having an enlarged rounded end 26.
Each upper tongue 24 is engageable with a groove 27 at the lower edge of a latching strip or plate 28. The groove is formed between an outwardly offset, downwardly projecting tongue portion 29 and the inner face of the crypt front 11. Each latching strip 28 is adhesively bonded to the inner surface of the marble or other front. The latching tongues 25 are each engageable with spring socket latch members 30, the backs 31 of which are adhesively bonded to the inner face of each marble front near the upper edge thereof.
The latching strips 28, plates 20, and supporting angles are all formed of suitable metal. It is preferred to employ aluminum or other metal which is resistant to corrosion. The spring sockets 30 are also formed of metal and may be any metal which has desired spring characteristics as well as resistance to corrosion.
The particular :bonding material which is used depends upon the type of material of which the fronts 11 are made. Where these fronts 11 are of marble it is preferred to employ an adhesive which has an epoxy resin base and in which there is a hardener additive capable-.of causing curing at room temperature. The strength characteristic of such adhesive to secure metal to marble should substantially meet the following specifications:
A lap shear strength in the neighborhood of 1,000 p.s.i. after 30 days of curing at 75 F. determined by ASTM testing procedure No. D-l002-64 and a T-Peel (pounds per inch of width) strength of 25 lbs. at 75 F. based on ASTM procedure No. D-1876-61T.
Where the fronts are formed of marble it is found that an adhesive manufactured by the Bonstone Corporation is highly satisfactory. This epoxy resin is marketed under the trade name Bonstone A-530, and there is an additive marketed under the trade name of Bonstone B-SOO. This bonding compound may be described as an amido-amine type of epoxy resin designed for room temperature curing. It is a resin which is Vbased on a diglycidal ether of bisphenol A, There are other epoxy resins on the market which may be used to bond the metal latching members to marble. Inasmuch as the fronts 11 may sometimes be formed of Indiana limestone granite, or other stone, or even of plastic, it is obvious that the exact type of adhesive or bonding compound will have to be selected to meet the requirements of the particular material used for the crypt front.
In installing a crypt front the latching strips 28 are preferably adhesively bonded to the inner face of the front 11 somewhat above the lower edge of the front, as shown in FIG. 2. Inasmuch as two fixtures are generally used on each crypt floor there should be two of the strips 28 secured in latching position. In addition, two of the spring socket members 30 must be bonded in suitable position to the inner face of each marble front near the upper edge thereof, as also shown in FIG. 2. Should there be any problems in installation the angles 15 may be adjusted outwardly by loosening the nuts 19, and the plates may be adjusted in a vertical direction by loosening the bolts 21. After the parts are in proper position a front such as the upper front 11 of FIG. 2 is lowered downwardly by gravity until the tongues 24 engage within the grooves 27. There is just enough play in the tongue-and-groove engagement at 24-27 due to the relief angle at 24 so that the upper edge of each slab may be swung outwardly enough for clearance in handling. During installation this upper edge is pushed inwardly, causing the rounded edges 26 of the tongues 25 to snap into the spring sockets 30. Thus each front will be securely held in place by completely concealed fittings, there being a small clearance space 32 between the upper edge of one marble front and the lower edge of another marble front.
Once the front is in closed position it cannot .be removed unless one has suitable know-how and has an instrument which can be inserted in the clearance space 32 to engage behind the upper edge of the lower slab 11 so that it can be pulled outwardly to release the tongues from the spring sockets 30. Then, with the upper edge swung out far enough to permit upward 4 lifting, the tongue-and-groove engagement at 24-:27 can be readily released.
As shown in FIG. 1 there may be any number of rows of crypts arranged vertically and horizontally, and it is clear from FIG. l that the latching plates 20 projecting from a crypt floor each have coaction with two marble fronts, i.e. with the lower portion of an upper front and with the upper portion of a lower front.
It is obvious from the above that with the preferred procedure above described, no drilling, sawing, or other mutilation of the stone fronts 11 is required, and the installation may be accomplished easily with relatively inexpensive fixtures.
While one of the principal objects of the present invention is to provide a latching arrangement wherein latching members may be adhesively carried by the stone slabs so as to avoid drilling or cutting into the marble, nevertheless certain features of the invention have utility regardless of the particular way in which the latching strips 28 and spring sockets 30 are connected to the inner faces of the slab fronts.
Various other changes and modications may be made without departing from the spirit of the invention, and all of such changes are contemplated as may come within the scope of the claims.
