   Hi,
   This invention relates to fruit juice extractors and, more particularly, to a wiper adjustably and removably mounted to the reamer of the extractor at a point above its juice strainer for selectively determining the amount of pulp passing through the strainer.
   
   2. Description of the Prior Art
   
   It was recognized early in the prior art that the passage of juice, in and through a fruit juice extractor, could be appreciably hastened by attaching a wiper to the handle of a manually operated juicer or the rotating reamer of an electrically powered juicer. Such improvements were directed solely at agitating the extracted pulp lying on the juicer's strainer in order to permit the extracted juice to flow around the pulp which had formerly blocked the strainer's drain holes. In most instances, the prior art wipers only lightly scraped the top surface of the strainer, while in some other instances, the wiper was tightly urged against the strainer, either intentionally or unintentionally as a result of wear or ineffective design. Consequently, depending upon a number of variables such as the diameter of the strainer drain holes or the type of fruit being squeezed, the pulp was either haphazardly forced through strainer holes into the juice or collected in the strainer. The prior art devices lacked versatility and predictability, were not effective, and could not be adjusted to meet these or other contingencies.
   
   SUMMARY OF THE INVENTION
   
   This invention relates to a detachably mounted wiper, which can be operated according to the user's desire, at different heights above the surface of a fruit juice extractor's strainer. At its closest point to the strainer, most of the extracted pulp will be forced through the strainer holes. Such a result may be desired merely as a personal preference or for health reasons to obtain maximum vitamin yield from the fruit or for indicating to customers in restaurants or other public eating places that the juice has been freshly prepared from whole fruit. On the other hand, it may be desired to prepare juice which is relatively pulp-free, as would be the case in feeding the very young or those with digestive problems or those who simply prefer their juice this way. This result can be achieved by moving the wiper to its highest point above the strainer surface.
   
   It is, therefore, an object of the present invention to provide an improved fruit juice extractor which can readily provide pulp-free or pulp-containing juice according to the user's desire.
   
   It is another object of the present invention to provide an improved fruit juice extractor having an adjustably and removably mounted wiper coupled to the driven reamer of the extractor.
   
   It is a further object of the present invention to provide an improved fruit juice extractor wherein the apparatus for selecting and determining pulp content of the extracted juice is simple to operate and easy to remove for cleaning and subsequent reassembly.
   
   Accordingly, a wiper having a relatively thin blade section and a mounting section is provided for use in conjunction with the reamer of a fruit juice extractor. The blade section is formed so that, in a mounted position, it is generally parallel to the surface of the juicer's strainer. The reamer is formed with appropriately shaped receiving and retaining means which serve to capture and retain the mounting section of the wiper, thereby causing rotation of the wiper simultaneously with the driven reamer. By selecting the height of the wiper blade above the surface of the strainer, the user can control the pulp content of the extracted juice. Thus, the pulp content of the extracted juice can be varied from a negligible amount to a predetermined maximum quantity which varies according to the type of fruit being used. It is also possible, where desired, to operate the juicer with the wiper removed so that completely pulp-free juice can be extracted.
