H.'Hill Company, Inc., Cleveland, Ghio, a corporation of Ohio ,Application May 24, 1957, serial No. 661,477 13 claims. (ci. 27-17) This invention relates to a casket, and particularly to the sealing means between the two separate hinged top ,sections or lids of the casket. Y It is customary in caskets of the type having twoseparate hinged top sections or lids, one for the head end of the casket and the other for the foot end thereof, to provide, in addition to marginal sealing means extending entirely around the margin of the body of the casket and cooperating with the top or lid sections, a sealing means between the two top sections or lids and extendingtransversely of the casket.

Ordinarily the sealing means between the two top sections or lids of the casket includes a transversegasket mounted on a rigid portion of one of the top sections or lids and engaged by a rigid portion of the other top'section or lid when the two sections are in closed position relative to the casket.

ln the usual arrangement the rigid gasket supporting portion on the one top section or lid forms the structural transverse support for the othery top section or lid when thesections are in closed position. However, unless the interrelatedy transverse portions of the two top sections or lids are accurately complementary to one another a perfect transverse seal may not be eitected between the two sections or lids when closed. i

If the interrelated transverse portions of the two top sections or lids are not accurately complementary in shape to each other the only compensation for the inaccuracies is the compressibility of the rigidly supported gasket itself. An object of the invention is to provide in a casket ofthe type having two hinged top sections or lids, improved and novel means carried by one top section or lid and engaged by the other top section or lid when the lids are closed and forming a transverse oating structural support and sealing means between the top sections or lids.

Another object is to provide in a casket construction an improved and novel transverse supporting and sealing means between the two top sections or lids of a casket and which means is carried by one section or lid and is self-compensating to accurately conform to the cooperating portion of the other top section or lid which engages it when the lids are closed and are drawn into tight sealing engagement with the marginal sealing means between the lids and the body of the casket.

A more specific object of the invention is to provide in a casket of the type having two hinged top sections or lids a oating transverse bridge carried by one of the ytop sections or lids and with said bridge mounting a sealing gasket engageable by a portion of the other top section or lid when the lids are closed and are drawn into sealing engagement with the body of the casket, wherefore the oating bridge forms a transverse structural support for the top sections or lids while the floating movement of the bridge, together with the compressibility of the gasket carried thereby, provides for accurate sealing adaptation of the gasket to the contour of the cooperating portion of the `other top section or lid, thus eiecting an improved rates atent V'ice Patented Jan. 20, 1959 body.

Further and additional objects and advantages inherent inthe invention and not explicitly recited above will 'bei come apparent hereinafter during the detailed description of an embodiment of the invention which is illustrated in the accompanying drawings forming a part of this speci# cation and wherein,

Fig. 1 is a perspective View ofra casket embodying the invention with the top section or lid at the head end of the casket in raised or open position while the top section or 'lid Vat the footend of the casket is in closed position.

Fig. 2 is a fragmentary view, partly in plan and partly in horizontal section, of the casket shown in Fig. 1 and is taken through the closed top section or lid at the foot end of the casket and substantially on irregular line 2-'2 ofFig. 3 looking in the direction ofthe arrows.

Fig. 3 is a vertical transverse section through the casket and is taken substantially on line 3-3 of Fig. 2 looking -in the direction of the arrows. l

Fig. 4 is a fragmentary vertical longitudinal section taken substantially on line 4-4 of Fig. 3 looking'in the direction of the arrows, and

Fig. 5 is a view similar to Fig. 4 'but on a reduced scalev and shows the top'section or lid at the head end of the casket closed and engaging the sealing means mounted on the oating bridge that'is carried by the top section or lid at the foot end of the casket.

The casket body 1i) can be of any desired or usual construction and the upper marginal end of the walls of the body mounts a marginal sealing means 11 in the form of a suitable sealing gasket as will be well understood in the art and which may have substantially the form of the marginal sealing gasket shown in the McEwan Patent No. 2,533,827, December l2, 1950.

The casket includes a hinged top section or lid 12 at the head end of the casket and a hinged top section or lid 13 at the foot end of the casket as will be well vunderf Vstood in the art.

The top sections or lids 12 and 13 are hinged along their rear longitudinal sides to the rear of the casket body by suitable hinging means such as indicated at 14 in Figs. l and 3.

The casket is provided with suitable means for drawing the top sections or lids 12 an'l 13 when closed into tight Sealing clamping VContact with the marginal sealing means 11. kThis means for drawing the tcp sections or lids into clamping contact with the marginal lsealing means 11 may take anv preferred form and per se constitutes no part of the invention.

The means just referred to may include headed pull down studs 15 on the marginal front l-fngitudinal portions of the lids 12 and 13. The studs 15 when Vthe lids are closed enter draw dovn devices 16 carried by the longitudinal marginal porticn of the front side of the casket body 10 and operated in unison frm the foot end of the casket by suitable operating means not shown. 'A suitable draw down arrangement of the character just referred to is shown in sa`d Patent 2,533,827 and also vvin Purkiss Patent 2,284,921, issued lune 2, 1942. i The adjacent ends of the top sections or lids 12 and 13 are provided, respectively, with end plates 17 and 1,8,

which when the top sections or lids are in closed position will lie closely adjacent and parallel to each other.

The lower edge of the end plate 18 of the top section or lid 13 is provided at the rear and front of the lid with straight portions 18a and 18h merging into the plane of the marginal sides of the lids and bearing upon the marginal sealng means 11 of the body 10 when the lids are in closed position.

The inner ends of the straight portions 18a and 18b of the end plate 18 connect with upwardly inclined edge portions 18e` and 18d, respectively. The inner ends of the inclined edge portions 18e and 18d of the end plate 18 interconnect with a straght edge portion 18e which is parallel to the straight edge portions 18a and 18b.

The lower edge of the end plate 18 has an inturned flange 19 extending toward the fcot end of the casket and shaped to conform to the straight and inclined portions of the lower edge of the plate 18. The free edge of the flange 19 may be provided with an upturned flange 20.

The flange 19 is provided with a series of openings 21, see Fig. 4, spaced apart transversely of the top section or lid 13 and in the preferred form of construction as presently contemplated therewill be three of these opening although this number of openings may be varied.

The flange 19 suppo-rts beneath it the floating bridge 22. This floating bridge is an upwardly facing channel member having the same general configuration as the lower edge of the end plate 18 but spaced downwardly from said edge. The straght portions of the floating bridge 22 which are beneath the straight portions 18a and 18b of the end plate 18 are substantially shorter in length than said straight portions 18a and 18b for a purpose later to be explained.

The floating bridge 22 is of a width such that it underlies that part of the flange 19 which is adjacent to the end plate 18 but extends beyond the end plate 18 toward the head end of the casket so as to also underlie the top section or lid 12 when the lids are closed as will later become more apparent.

The width of the floating bridge 22 approximately is such that it 4will underlie that half of the width of the flange 19 adjacent to the end plate 18 and half of the width of a similar ange on the end plate 17 and later to be referred to, although it will be understood that the width of the floating bridge 22 could vary so as to have a somewhat different relationship with respect to the widths of said flanges.

The floating bridge 22 has secured to it a series of upwardly extending bolts 23 which pass through the openings 21 in the flange 19 previously referred to, there being in the present embodiment three -of the bolts 23, two of which are shown in Figs. 2 and 3 while the third would be located in the broken away central portions of said figures.

The bolts 23 are secured to the upper side of the bottom of the channel-shaped floating bridge a relatively substantial distance to one side of the longitudinal center line of the bridge for a purpose later to become apparent. The bolts 23 are provided with relatively thin heads 24 which are welded or otherwise secured to the upper side of the bottom wall of the floating bridge.

The channel-shaped oat'ng bridge 22 mounts a sealing means 25, later to be referred to more in detail, and which sealing means is substantially rectangular in cross section and preferably is formed of a compressible natural or synthetic rubber adhered to the floating bridge by a suitable adhesive or cement. The flange on the left-hand side of the bridge 22, as viewed in Fig. 4, is of less height than the other flange of the bridge to provide for greater compressibility of the sealing means 25 that is adjacent thereto.

Thebolts 23 extend through the sealing means 25 as well as the openings 21 and their upper ends project above the flange 19 and mount thereon washers 26 and nuts 27. When the floating bridge is secured to the flange 19 the nuts 27 are not tightly screwed down on the bolts 23 and, in fact, are only screwed down enough to bring the upper side of the sealing means 25 into engagement with the flange 10 and such that they can be unscrewed manually by the fingers.

In view of the fact that the nuts 27 are not firmly tightened down on the bolts and there is a clearance between the wall of the open'ngs 21 and the circumference of the bolts the floating bridge 22 can have limited rocking movement in multiple directions relative to the flange 19, it being recalled that said bolts are located a substantial distance to one side of the longitudinal center line of the floating bridge whereby certain of said rocking movements will have a relatively long radius.

The opposite straight end portions of the floating bridge 22 do not engage the margnal sealing means 11 when the top section 13 is in closed position but are supported by the horizontal arms of the angle brackets 28, the vertical arms of which are rigidly secured to the inner sides of the rear and front side walls of the body 10. These angle brackets 28 provide a structural support for the opposite ends of the floatng bridge when the top section 13 is closed but do not prevent the floating bridge from having said limited rocking movements.

The marginal sealing means 11 substantially midway of the longitudinal length thereof at the rear and the front sdes of the body 10 is cut away and substantially rectangular sealing means 29 are vulcanized to the ends of the sealing means 11 and are secured to the marginal upper edge of the rear and front walls of the body l0. These sealing members 29 on their inner longitudinal edges and substantially midway of the ends of the members are provided with extension portions 29a which overlie and engage a portion of the horizontal arms of the angle brackets 28. The opposite ends of the floating bridge engage the portions 29a adjacent their free ends and compress the same. The extension portions 29a and the sealing members 29 are molded to have a rectangular cross secton.

The sealing members 29 also are provided on their upper sides and in alignment with the portions 29a of the members in the transverse direction of the body with slight depressions or recesses 30 which are indicated for illustrative purposes as of rectangular configuration.

The opposite ends of the sealing means 25 where said means extends beyond the opposite ends of the floating bridge 22 have their undersides formed on a radius as clearly indicated in Fig. 3. Also the opposite ends of the sealing means 25 terminate in very thin portions which may be termed feather portions as indicated at 25a in Fig. 3 and which thin portions overlie the depressions or recesses 30 in the sealing members 29 for a purpose later to become clear.

The end plate 17 of the top section or lid 12 has its lower edge shaped substantially the same as the lower edge of the end plate 18 of the lid 13 and said lower edge of the end plate 17 is provided with a similarly contoured flange 31 extending laterally of the end plate toward the head end of the casket.

We may now assume that the section or lid 13 is in closed position and that the top section or lid 12 is swung downwardly to closed position. This movement of the lid 12 brings the flange 31 of the end plate 17 of the lid into engagement with the sealing means 25. Also the studs 15 of the lid 12 enter their cooperating draw down devices 16 and when the devices 16 are operated in unison from the foot end of the body the lids 12 and 13 will be drawn down tightly into sealing engagement with the marginal sealing means 11. Also the flange 31 will be drawn into tight engagement with the sealing means v25 and will exert a compressing force on said sealing means.

Although the flange 31 ls intended to be complementary t0 the, Sealing means 25 and the fleeting bride@ 2.2 it may not have'the same engaging contact with the Sealing means 25 throughout the entire length thereof and if this is the situation thesealing means 25, due to its compressibility and because of the universal rocking or adapting movements of which the floating bridge is susceptible, will conform itself to the entire area of the flange 31 to provide a complete and eiicientseal therebetween. Also the drawing down of the lids 12 and 1.3 by the draw down devices 16 will press the curved under surfaces of the opposite ends of the sealing means 25 into close sealing engagement with the upper surfaces of the extensions 29a of the sealing members 29. Furthermore, the drawing down of the lids 12 and 13 will exert pressure on the thin or feathered end portions 25a at the opposite ends of the sealing means 25 and cause said end portions to be pressed into the depressions or recesses 30 of the sealing members 29. Consequently an effective hermetic seal is provided transversely of the casket between the top sections or lids 12 and 13 and also between the same, the opposite ends of the sealing means 25 and the sealing members 29 at the front and rear marginal locations of the body.

From the foregoing description it will be noted that the novel tioating bridge 22 which carries the transverse sealing means 25 provides for self-adaptation of the sealing means 25 to the contour of the liange 31 on the end plate 17 of the lid 12 to assure a perfect seal between the lids 12 and 13 transversely of the casket. Not only does the floating bridge 22 perform this function but it also performs the function of a transverse structural supporting element for the lids 12 and 13, thus imparting stability and strength to the casket.
