The invention relates to mechanism for apparatus intended for use by morticians, funeral directors and the like for the purpose of covering a grave automatically as the casket is lowered.

It is well known that at cemetery services it has now become the practice to place within and about a grave a lining or covering of material which is formed as the representation of grass mats, the purpose being to cover the raw soil and detract from the harsh and cold appearance of the grave. It is also known that numerous me-' chanical devices have been devised for the purpose of gently and slowly lowering the casket as the ceremony progresses, such devices rendering unnecessary the presence of mechanics with the well known hand lowering straps or other devices of the past. However, notwithstanding the progress which has been made along the above mentioned two lines, there still exists a certain amount of shock to the feelings of bereaved spectators when the casket disappears into the yawning void of the grave and it is on account of this latter mentioned fact that I have devised the present invention which has for its general object the provision of novel means associated with and operated by the casket lowering mechanism for automatically drawing and folding the imitation grass mats over the top of the grave as the casket is lowered, the grave being consequently covered by a mound of mat-like material which appears to be sod, thus creating an impression far less harrowing to the sentimentalities of bereaved spectators than would otherwise be the case.

An important object of the invention is to provide a grave cover applying means which may be attached to and used in conjunction with an ordinary type of casket or vault lowering mechanisrn, various features of adjustment being provided for the purpose.

Another object of the invention is to provide a cover applying mechanism which may be used to equal advantage in association with caskets or vaults, a simple adjustment being provided which will take care of the difference in the height of the two types of receptacles.

A further object of the invention is to provide a grave cover applying mechanism equipped with means which may be disposed against a wall of the grave for bracing purposes or which may be engaged within the rough box for the purpose of guiding the casket thereinto so as to avoid the possibility of the casket striking against the edge of the rough box as may occur in the event that the walls of the grave are not exactly plumb.

A still further object is to provide a mechanism of this character which is collapsible for convenience in transportation but yet which will be rigid when in set up condition ready for use.

Another important object of the invention is to provide an apparatus of this character which 5 will be noiseless in operation.

An additional object is to provide a device of this type and for this purpose which in addition to possessing the above mentioned advantageous characteristics will be simple and inexpensive to 10 make, easy to set up and adjust, positive in action, efficient in operation, durable in service, and a general improvement in the art.

To the attainment of the foregoing and other objects and advantages, the invention preferably 15 consists in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which:

Referring more particularly to the drawings, the letter A designates a grave within which, as shown in Figure 2, there is located a rough box B to receive the casket, not shown. Mounted in the usual manner upon the surface of the ground at the grave is a conventional type of lowering mechanism here represented as including corner uprights C upon which or within which are mounted rotatable side rails D carrying the usual webs or straps E upon which the casket, or the vault as the case may be, is initiallyplaced, the casket or vault being permitted to descend by the unwinding of these webs or straps from the side rails D as they are permitted to rotate by the weight of the casket upon the straps or webs. Of course it is well known that a lowering 7 mechanism involves or embodies a brake structure which controls the rate of descent of the casket or vault as the ceremony progresses. The present invention is not at all concerned with the lowering mechanism itself as it can be used in connection with various types. 7

In carrying out the invention I provide two structures or devices which are duplicates, one being located at eachend of the grave and attached to the cross rails F of the lowering device. Each of these devices comprises an upright 20 channel shaped in cross sectionas clearly indicated in Figure 14 and connected at its upper end with a T-shaped head 2| which may be conveniently formed as a casting and to which are pivoted, at 32, arms 23 within which are telescopically slidably engaged extensions 24 terminating in saddle members 25 of semicylindrical shape designed and adapted to be engaged upon the side rails D of the lowering mechanism. In order to avoid or reduce friction between the side rails and the saddle members, the latter are preferably equipped with ball bearings 26 located within recesses 21 and retained therein by means of apertured plates 28 secured in place as by screws 29, as clearly shown in Figures 12 and 13. Obviously these bearing balls 26 will contact with the side rails of the lowering mechanisrn'and will turn in the recesses within which they are disposed as the lowering mechanism is operated to permit descent of the casket or vault. For the purpose of holding the arms 23 in extended position at right angles to the upright 20, I provide braces formed of sections 30 and 3| pivotally connected at 32 with a rule joint and pivotally connected with the upright and arms at brackets 33 and 34, respectively. The extended position of one of thearms is shown at the left side of Figure 4 V and the folded position is shown at the right side of the same figure, it being noticeable that when the rule joint 32 is broken and the brace sections 30 and 3! folded to lie against each other the arm 23 will extend down alongside the upright 20 and in parallel relation thereto so that the device will occupy butlittle space instorage or during transportation.

sides of the grave in parallel relation to the side rails D of the casket lowering mechanism. The purpose of these slots 44 is to enable thepipes 45 to be detached from the arms 43 when it is necessary or desirable to transport the device. It 5 will be noted that the extensibility of the arms 23, that is to say their provision with the extensions 24 carrying the saddle members 25, will enable the device to be used in association with lowering devices adjusted for graves of widely 1Q varying widths. The purpose of the adjustably disposed ball members 40 will be explained hereinafter as the adjustability is necessary depending upon whether a casket or a vault is to be buried. The arms 23 and the extensions 24 slidably engaged therewithin are formed with slots 46 and 41, respectively, for the accommodation and to permit sliding movement of the angular arms 43 which drag or carry the pipes with them.. It is of course to be understood that 20 I along the slot 48 and equipped, preferably, with 30 a wing nut 5! which is provided for the purpose of enabling this plate to be secured at any desired vertically adjusted position depending upon whether it is necessary or desirable to handle a casket or a vault. The plate 49 also carries a 5 screw 52 slidable along the slot 48 and equipped with a nut 53 but this is simply for guiding purposes as the screw carrying the wing nut 5| is sufficient for clamping purposes to maintain adjustment. w

slidably mounted within the channel shaped upright or standard 20 is a carriage 54 of any ordinary or preferred construction and equipped with a screw eye or hook 55, or its equivalent,

with which is connected the lower end of one of 45.,

the cables 38 or 39, the two being connected with each other at some point above the screw eye though it is of course conceivable that both of the cables might be extended to the screw eyeif preferred. The point is that when this carriage or 50 frame 54 moves, the cables and consequently the angular arms 43 will move correspondingly.

Pivoted at 56 within the frame or carriage 54 is a' treadle of trip arm 51 which normally projects horizontally and which is disposed in the path of travel of the casket or vault so as to beengaged thereby for the purpose of applying a pull upon the cables 38 and 39 for moving the pipes or tubular members 45 toward each other to draw the imitation grass mats over the grave. connected at 58 with each treadle 51 is a rod 59 extending through a. coil spring 60 and slidable through a cylindrical member 6| pivoted within the upright or standard 20. The frame or carriage 54 is represented as equipped with wheels or rollers 62 which bear against the inner walls of the channel shaped upright 20, these wheels being for the purpose of insuring free vertical movement of the carriage when the treadle 51 1s engaged and depressed by the casket or vault.

The treadle 51 travels within the standard or upright 20 when engaged by the casket or vault. and to make this movement free and easy it is preferable to provide a wheel or roller 63 which Pivotally is journaled at the lower portion and which bears against the vertically adjustable plate 49.

In order to brace the device against the wall of the grave or to effect guiding of the casket into the rough box H, I provide a casting 64 at the lower end of the upright or standard 20, this casting being provided with vertically extending holes 65 through which extend angularly shaped rods 66 Which diverge and which are held in adjusted position by means of set screws 61, the purpose being that these rods may be adjusted rotatably so as to engage against the end wall I of the grave as shown in Figure 5 or within the rough box H as shown in Figure 2, depending upon circumstances. These rods 66 are of course longitudinally adjustable to take care of the depth at which the rough box is disposed.

Another feature of importance is the ability of the device to be associated with lowering devices of different types. As all such lowering devices embody telescopically engaged transverse members F it becomes necessary to provide a mode of attachment of the device to the lowering mechanism, such attachment being necessarily adjustable for obvious reasons. In the present instance I have shown the heads or castings 2! as formed with sockets 68 receiving stubs 69 projecting from inverted semicylindrical saddle members 10, set screws H being provided for the purpose of maintaining an adjusted position.

In the use of the device, it should be understood that one is located or disposed at each end of the grave, the saddle member 10 of each being engaged over a transverse member F and the saddle members 25 being engaged over the side rails D of the lowering mechanism. Owing to the provision of the ball bearings 26 it is clear that the side rails of the lowering mechanism may turn freely with respect to my attachment without undue friction. The end rails F do not turn so there is no necessity for any friction eliminating features at this point. The rods 66 are adjusted to bear either against the end wall I of the grave or against the inside of the rough box, depending upon which is preferred. In some cases it occurs that the walls of the grave are not exactly plumb and in such an event it is highly desirable to dispose the rods 66 within the rough box so that the casket will be guided thereinto.

The position'of the treadle 51 depends upon whether a casket or a vault is to be buried. If a casket is to be deposited, of course within the usual rough box, the plate 49 is disposed at the upper limit of its movement and is secured by tightening the wing nut 5|. This means that a larger portion of the slot 48 is exposed. Assuming that this is the condition, and that the treadles 51 at the two ends of the grave project horizontally at their uppermost elevation, it will be seen that when the casket is placed upon the straps or webs E and the-lowering mechanism is operated, when the casket, in its descent, strikes against the two treadles 51, it will move them downwardly, thereby applying a pull upon the cables 38 and 39, and drawing the arms 43 toward each other by virtue of the fact that the stops 4!! will engage against these arms. Inasmuch as the imitation grass mats are draped over the pipes or tubular members 45 it is clear that the engagement of the angular arms 43 within these pipes will draw them toward each other, thereby moving the grass mats over the grave in elevated position with respect thereto, depending upon the height of the standards C and producing the effect of a grass mound position by the springs 60.

which will be much less harsh than either an open grave or a bank of clay.

In some instances the casket is originally enclosed within a steel box or vault and in such an event there is no necessity for using a rough box. Under such circumstances it is necessary to lower the treadles 5! owing to the diiference in height or depth of a vault as compared with a casket. Such being the case the wing nut 5| is loosened so that the plate 49 may be slid down to the lower 10 limit of its movement, after which the Wing nut is retightened. The treadles 51 at the two ends of the grave are then of course several inches lower than is the case when a casket is to be buried. When the lowering mechanism of any type employed is operated the vault will be lowered and when it strikes the two treadles 51 it will move the carriage 54 downwardly. This action is the same regardless of whether a casket or a vault is to be buried and when the treadles are moved 20 downwardly, they will slide within the standards or uprights 26 until they reach the lower ends oi the slots 48 whereupon there is nothing to hold them horizontal and they will therefore swing downwardly from the horizontal position shown '25 in Figure 8 into the vertical position shown in Figures 9 and 10. When this occurs the heel por- -tions of the treadles will engage against the lower ends of the slots 48, the treadles being maintained in this position owing to the fact that the 30 rods 59 go past center and are maintained in such Owing to this condition the cables 38 and 39 are held under tension with the pipes or tubular members 45 drawn closely together. The advantage of this is that 35 the weight of the artificial grass mats cannot draw the pipes or tubular members 45 apart and they will be consequently held close together so that the mats will meet at the longitudinal center line of the grave, thereby producing the effect 01' 4o sodding and consequently shielding the grave so that it will have the appearance 01' being entirely covered over and hiding the soil.

From the above description and a study of the drawings it will be apparent that I have thus 45 provided a comparatively simple and yet highly efficient device for the purpose specified. Owing to the pivotal mounting of the arms it is clear that they may be folded down to extend along the uprights 20 as indicated at the right side of 50 Figure 4 for convenience in transportation and storage. Moreover owing to the fact that the rods 66 are not only adjustable but also removable the length of the device may be materially reduced. The adjustability as to the length of 55 the stubs 68 will enable the device to be used in association with lowering devices of diiferent types and the same is true of the extensibility of the members 24 with respect to the members 23 in order to compensate for differences in the widths of different graves. In case caskets of difierent heights or depths are to be buried the adjustability of the plate 49 is of importance as it is not necessary that this plate be disposed at the extreme maximum or the extreme minimum height, any variation in inches of the depth or height of the casket being taken care of by this adjustable feature. Another feature of note is that owing to the provision of the rod 59 and 7 spring 66 which constitute a beyond center look any retrograde movement of the mats is prevented. In addition, the entire device has proved to be noiseless in operation. It is thought from the foregoing that the construction, operation 15 scope of the claims hereunto appended.
