     BACKGROUND 
     1. Field 
     This application relates to four post book holder designs. 
     2. Prior Art 
     My patent searching consisted of looking at book holders at book stores. Further searches at WWW.freepatentonline.com reviled many four (4) post designs. There were book holders with page retainers that have to be moved in order to turn book pages. Page retainers in my design are easy to adjust. Once adjusted only slight adjustments are necessary during the reading of the held book. Page retainers do not have to be readjusted or moved to turn the read page of a held book. 
     SUMMARY 
     Holder consist of a base with legs to adjust reading angle. A upper movable fence and a lower stationary fence are provided to hold books in place. Movable tab assemblies with page retainers are attached to these fences in slots provided. Tab assemblies are attached to the fence slots with coil springs and steel pins. This attachment allows the tab assemblies to be moved perpendicularly and/or side to side. This tab movement results is complete adjustability of the page retainers. Turning of the held book&#39;s read page is accomplished without any need to move or adjust the tab or page retainer assemblies.

     Detailed Description of FIGS. 1 to 9 
       FIGS. 1 and 2  show the top and bottom of the holder with the top fence  12  moved up.  FIG. 2  shows the slide  24  which allows the top fence to move. The movement of top fence allows books of various sizes to be installed in the holder.  FIG. 1  further shows the four tab assemblies  16 , 18 , 20 , 22  fastened to the upper and lower fences. 
     The tabs are fastened to the fences as shown in  FIG. 4 . Sec A-A. Tabs are spring loaded to the slots  FIG. 1 ,  50 , 52 , 54 , 56  on each fence. Tabs can move perpendiculy, side to side, relative to the fences in the slots provided. Because of this movement the page retainers  38 , 40 , 42 , 44  can be adjusted to hold book pages down. 
     FIGS.  5 , 6  show the top fence  12  Sec C-C and bottom fence  14  Sec D-D. These two sections show the cover retainer bars  46 , &amp;  48 . Book hard covers slip under these bar retainers when hard cover books are retained by the holder.  FIG. 8 , Sec B-B shows a hard cover of a book under the retainer bar  46 . 
       FIG. 9  shows the holder in storage mode. Legs are folded up. Page retainer tab assemblies are folded down. 
     Operation FIG.  1 , 2 , 4 , 5 , 6 , 7 , 8 , 9   
     Beginning with holder in storage mode  FIG. 9 . Place holder on a horizontal surface. Adjust legs  26 , 28  and lock  60 , 62 . Open base area  10  by moving upper fence  12  up obtaining space needed to accommodate book. Stand up the four (4) page tab assemblies  16 , 18 , 20 , 22 . To install a hard cover book first rotate the four (4) To install a hard cover book first rotate the four (4) page retainer assemblies  30 , 32 , 34 , 36  outward from the holder base. This will allow the book&#39;s pages, after installation, to be turned to the readers chosen start page without interference from the page retainers  38 , 40 , 42 , 44 . Open book so that its back binding can be laid flat on the holder base  10 . Insert bottom book binding under lower fence retainer bar  48 . Holding open book flat to the base  10 , close upper fence  12  to top of book&#39;s pages. When the top fence  12  is moved down the book&#39;s hard cover will slip under the top fence retainer bar  46 . The book, with its cover held down by the retainer bars  46 , 48 , is now moved to extend beyond the top fences  12  right edge. This overlapping of the top fence right edge is required in order to facilitate page turning. 
     With the open book positioned in the holder the page retainer assemblies  30 , 32 , 34 , 36  can be rotated back so that the retainers  38 , 40 , 42 , 44  are positioned over the book&#39;s pages. 
     Adjustments of the page tab assemblies  16 , 18 , 20 , 22  is done by moving them in the fence slots  50 , 52 , 54 , 56 . This positions the page retainers  38 , 40 , 42 , 44 . Tab assemblies  16 , 18 , 20 , 22  are spring loaded and single pinned to the fences thru the fence grooves  50 , 52 , 54 , 56  ( FIG. 4 ). This allows them to move perpendicularly and/or side to side. This movement allows a wide range of adjustment of the page retainers  38 , 40 , 42 , 44 . 
     These adjustments will result with the pages of the book being held down in an acceptable reading position. Proper retainer  38 , 40 , 42 , 44  adjustments will result in a unobstructed view of the book&#39;s words. Page retainers  38 , 40 , 42 , 44  can be rotated, if required, to clear book words if the book top and bottom margins are narrow. In this position they will still retain the book pages. Room is left between the adjusted book pages and the holder base. This is to facilitate page turning. 
     Page turning without any further adjustments to the page tab assemblies  16 , 18 , 20 , 22  is accomplished by placing the tip of the right hand index finger at the top edge of the book&#39;s right page and lifting the page. The lifted page will slip out from under the top right page retainer  40 . When the page is moved to the left side of the book holder the page will slip out from under the bottom right retainer  44 . Since space was left between the open book retained pages and the holder base, the turned page can easily be tucked under the left top and bottom page retainers  38 , 42 . The turning of pages in this holder is much like turning a hand held book page. Turning of pages is accomplished using one hand only. At no time during the turning of pages is any further adjustments required of the page tab assemblies  16 , 18 , 20 , 22 . Some minor adjustments of the tab assemblies  16 , 18 , 20 , 22  may be necessary as the book is being read. This is due to the book&#39;s thickness and page springiness changing as the pages of the book are moved side to side. 
     The installment and holding operation of books without hard covers is accomplished the same way as explained above. Of course there are no hard covers to slip under the fences  12 , 14  cover retainer bars  46 , 48 . The lack of hard covers will not effect the holding of these types of books since all books in this holder are held in place by the page tab assemblies  16 , 18 , 20 , 22  and the leading edge of the hard cover retainer bars  46 , 48 .
