     BACKGROUND OF THE INVENTION 
     My U.S. Pat. Nos. 7,591,404, titled Easy Inter Burial Container, 8,046,883, titled Edged Non-horizontal Burial Containers and 8,104,153, titled Non-horizontal Burial Methods, disclose several types of threaded screw-in and bladed self digging burial containers which require rotation to be screwed or self dug into the ground and thus illustrate the need for the present invented apparatus. The invented apparatus is specifically designed to provide means of gripping, lifting, transporting, positioning and rotating the screw-in and self-digging burial containers disclosed in these patents. 
     Current practice for interring horizontally placed burial containers is to dig a hole approximately seven foot deep, by four feet wide by eight feet long and store the removed receiving material for later filling of the hole. A crypt is usually placed at the bottom of the large hole and the coffin is lowered into the crypt. The crypt lid is set in place and a portion of the removed material is placed and tamped around and on the crypt. Grass and other such covering is placed over the top to restore the original appearance of the area and the surplus material is removed from the site. All of which is time consuming and expensive. 
     A particular problem usually occurs when an installation is in a high water table area. A hole soon fills with water, presenting a near impossible problem for a proper horizontal grave site. Screw-in or self digging burial containers solve the problem by using the apparatus of the present invention for vertical interments. These interments do not require large pre-dug holes as these burial containers can be screwed or self-bored directly into the damp ground by this invention. 
     FIELD OF THE INVENTION 
     The present invention relates to apparatus which, when attached to a suitable vehicle, can pick up a threaded screw-in or a bladed self digging burial container, hold the burial container while the vehicle travels to another location and reposition the burial container to the angle in which it is to be interred. The operator of the vehicle and the invented apparatus can move a shaped wrenching section of the apparatus over a matchingly shaped end of said burial container and cause the wrenching section to rotationally screw or dig the burial container into the ground. 
     RELATED ART 
     Large cranes, back-hoes, tractors and similar vehicles are often fitted with various types of augers for boring holes in earth into which are inserted piles and building anchors. The same types of equipment are also fitted with rams for forcefully inserting heavy pilings, posts and building anchors where the inserted item is forced into the ground and left. Many of these machines have drives that fit into a receptor in the item to be inserted. None of this type of apparatus can pick up an item, such as a non-horizontal burial container, transport it to the place where it is to be interred ground, maneuver it into position, engage said burial container with a wrenching device, rotate said burial container to cause it to enter the ground and move a section of the apparatus out of the way so that the top of the interred burial container can be set to ground level by the wrenching device. The same types of vehicles used in the boring and ramming of post holes and pilings are often fitted with clamshell buckets or other digging devices and used to dig the large holes required for current horizontal burial containers. These large holes require removal of a large amount of dirt. After a horizontal burial, about half of the dirt is replaced to fill the hole and for ground cover and the rest is transported to another location requiring several vehicle trips. 
     The present invention is designed to handle non-horizontal threaded screw-in and bladed self digging burial containers, which can replace current horizontal burial containers and the large holes and large land area required for horizontal interments. 
     OBJECTS OF THE INVENTION 
     It is a main object of this invention to provide apparatus with which to transport, position and rotate threaded screw-in and bladed self digging burial containers. 
     It is an object of this invention to reduce the time and cost of a burial by providing means to inter bodies in threaded screw-in or bladed self digging burial containers thus eliminating the digging of a large hole as well as reducing the labor required to handle the left over dirt and clean up and restore the burial site. 
     It is yet another object of this invention to solve the problem of water filling an initial hole for burial containers in high water table areas, by providing a means to non-horizontally screw, bore or ream burial containers into the ground. 
     SUMMARY OF THE INVENTION 
     An apparatus of the present invention is mechanically fitted to a vehicle and the power supply of the vehicle is hooked up to the apparatus. The operator moves the apparatus over a screw-in or self digging burial container lying in a horizontal or other position and sets the shaped wrenching device of the apparatus firmly on the matchingly shaped head of the burial container. The operator closes the gripping arms of the apparatus over the burial container, raises the burial container off of the ground and transports the burial container to the grave site. The operator then turns the burial container to the preferred interment position and maneuvers the burial container over and down onto the interment spot. The operator slightly loosens the gripping arms from around the burial container and begins rotation of the wrenching device, in the correct direction, while pressing the burial container downward. 
     The preferred embodiment of this invention incorporates the use of hydraulic, electric, air or mechanical powered equipment to inter screw-in and self digging burial containers. Regularly available backhoes, tractors, cranes, loaders, forklifts and the like are fitted with the apparatus of the present invention. This apparatus is made using common metal working practices as it is composed of fabricated metal frames, to which are attached metal fabricated gripping, wrenching and rotating sections, along with commonly available motors and power supplies. Together, these components make up a POSITIONING AND ROTATING APPARATUS FOR INTERRING SCREW-IN AND SELF DIGGING BURIAL CONTAINERS. 
     The invented apparatus handles and maneuvers said types of burial containers into position and then rotates them into the ground or other receiving material. The invented apparatus is particularly useful to inter said types of burial containers into water covered, swampy, muddy and high water table areas, using the water to assist interment. The invented apparatus is also used to quickly and easily place hollow screw-in or self digging units, in this case called coffers, containing food, water, hardware, information and or other materials safely and securely into dirt, sand, mud, snow or even under water. Other embodiments, ramifications and combinations of the design shown herein are equally preferred.

     DETAILED DESCRIPTION OF THE INVENTION 
     The apparatus of the present invention is basically characterized by a first support frame,  103 ,  FIG. 1 , which attaches to a powered vehicle,  100 ,  FIG. 1 , and which has a horizontally extending member,  116 ,  FIG. 4 , over which a second member,  106 ,  FIG. 1 , is mounted with bearings between the two members. The second member rotates around the first member as a second support frame. An extendible and retractable linear actuator,  107 ,  FIG. 1 , is mounted on an arm,  102 ,  FIG. 1 , which is attached to the second support frame, and is attached at its opposite end to a fixture,  117 , on the first support frame to control the relationship between the first and second support frames. This arrangement provides for the second support frame to be rotationally controlled between a horizontal and a vertical position. A bi-directional motor,  104 ,  FIG. 1 , is mounted on the second support frame. A wrenching device,  122 ,  FIG. 1 , matching the shape of the headpieces of screw-in and self digging burial containers, coffins or coffers, to be interred is mounted on the output shaft,  108 ,  FIG. 1 , of the motor. 
     The second support frame has a fixed cross beam,  110 ,  FIG. 1 , extending out to each side on which are affixed brackets to hold the upper ends of extendible and retractable linear actuators,  101  and  105 ,  FIG. 1 , which are attached at their opposite ends to arms,  111 ,  FIG. 1 , on each side of the main body of the second support frame. The arms,  111 ,  FIG. 1 , pivot on a second fixed cross beam,  109 ,  FIG. 1 , and extend downward past the pivot point. The section of these arms below the pivot point contain hinge lines for front gripping arms,  112  and  113 ,  FIG. 1 , and rear gripping arms,  119  and  121 ,  FIG. 2 . Extendible and retractable linear actuators,  114  and  115 ,  FIG. 1 , attached to the pivot arms at one end, between the hinge lines, and to the gripping arms at their opposite ends, provide control for opening and closing the gripping arms 
     The invented apparatus is attached to a vehicle,  100 ,  FIG. 8 , and hooked up to the power of the vehicle. The gripping arms,  113 ,  FIG. 8 , are opened and the apparatus is rotated to align with the burial container,  131 ,  FIG. 8 . The burial container, having a shaped headpiece,  140 ,  FIG. 8 , is picked up by the apparatus, with its shaped wrenching device,  122 ,  FIG. 8 , fitted over the headpiece of the burial container. The gripping arms,  113 , are closed as shown in  FIG. 9 . 
     The vehicle moves the burial container to the grave site, as illustrated in  FIG. 9 . Once the burial container is at the spot where it is to be interred,  145 ,  FIG. 10 , it is rotated by way of an extendible and retractable linear actuator,  107 ,  FIG. 1 , to be perpendicular to the ground surface. The burial container is then pressed downward into the receiving material. This action securely sets the top of the burial container into the wrenching device,  122 ,  FIG. 1 , mounted on the motor. The gripping arms  112  and  113 ,  FIG. 1 , are then loosened slightly to reduce drag and the motor is rotated to cause the wrenching device to rotate the burial container in the proper direction. The burial container, by way of its screw threads or cutting edges, enters and continues into the ground or receiving material,  FIG. 11 . Downward pressure and rotation are maintained on the burial container until the bottom edges of the gripping arms,  112 ,  FIG. 11 , approach ground level,  142 ,  FIG. 11 . The gripping arms,  112 ,  FIG. 12 , are then opened and pivoted upward away from the ground, allowing the entire apparatus and burial container to continue downward until the wrenching device,  122 ,  FIG. 12 , has interred the burial container to a position at or below ground level,  142 ,  FIG. 12 .
