The copyright owner has no objection to the facsimile reproduction by any of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.  
       BACKGROUND OF INVENTION  
       [0002]     This invention relates to the bulk shredding of documents, credit cards and other data storage materials by the average consumer in the home or small business. Hereinafter the small business or home user will be referred to as the consumer, but not limited to, but also to include any user, including lawyers, doctors, government workers, artists and authors and other professionals.  
         [0003]     The use of shredders today by the consumer is typically done in the home or small office. Therefore, the shredders commonly used are limited by types of shredding but also limited by capacity and types of material that can be shredded.  
         [0004]     The shredders commonly used produce either straight or cross sectional cuts, which do not provide the level of destruction, security or secrecy necessary for protecting, confidential medical information or personal and business financial information in today&#39;s environment of identity theft and misuse of personal information.  
         [0005]     The shredders used by these consumers are also limited by their capacity to handle large volumes of materials. Typically these shredders can only handle single, individually fed items, but generally no more than 20 sheets of paper at one time. Any attempts at large capacity shredding may result in device malfunction.  
         [0006]     Another draw back is the limitation to the types of materials that can be shredded in the devices currently being used. These shredders are single use devices used for either destroying paper documents or plastic documents such as credit cards or compact discs (CD&#39;s).  
         [0007]     These drawbacks in terms of types of shredding and limitations with capacity and limitations on types of materials that may be shredded are not as great a problem as the concern for convenience and expense of the shredding process.  
         [0008]     Today, in order to do bulk shredding you have to purchase and expensive bulk shredder or contract these services out to a bulk shredder service company. Bulk shredders are cost prohibitive for the average consumer or small business.  
         [0009]     The consumer would have to purchase an expensive bulk shredder or contract these services to a bulk shredding company. But bulk shredding is cost prohibitive for the consumer or small business because these devices are too expensive to purchase and maintain; and therefore, it is not a feasible proposition. Moreover, consumers often go through periods or cycles when bulk shredding is greatly needed. Other times the need may only be for limited quantities to be shredded, making the purchase of bulk shredders infeasible. In addition, bulk shredders are large items, which take up a great amount of space, makes lots of noise and creates enormous amount of waste product.  
         [0010]     In order to reduce or limit this expense, need for maintenance, lack of space (special constraints), need for outside third party contracting: a bulk shredder, unlike one that currently exists today, which optionally provides the consumer with levels of destruction or obliteration, through a service charged by time and/or capacity built within one unit, would provided a different and new option.  
         [0011]     Summarily there are no shredders today that do bulk shredding that charge either by the capacity, time or level of shredding built into one unit, that allows a consumer to conveniently take his/her bulk shredding to a location, shred the materials themselves and be charged for the shredding by a self contained shredder.
