Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention is directed to devices for assisting in feeding stock material on a wood shaper, a router table or a table saw and more particularly to devices for assisting in feeding stock material on a wood shaper, a router table or a table saw in normal woodworking operations, precision processing of material and in forming small pre-cut panels. 
         [0003]    2. Description of Related Art 
         [0004]    The use of fingers, finger boards, hold down devices, power feeders, fences and a miter slot accommodating miter gages, sliding miter jigs and other accessories milled in the stock support tables of wood shapers, router tables and table saws is representative of the prior art that has addressed apparatus associated with the processing of materials. The invention described does not solve the problem of high precision processing of stock material and small work pieces of material with accuracy, safety, speed and consistent results. 
         [0005]    These systems and methods allow for the manufacture of medium size work pieces only, in a cumbersome manner, while the operator contends with the issue of clogging. Cut material debris in a recessed miter slot may result in the loss of precision and hazard to the operator. 
         [0006]    There is no system that currently exists that can easily be converted to process small work pieces with great precision, flexibility of positioning and offer operator ease and safety. 
         [0007]    Existing systems do not produce precision consistent results, efficient use of the operator&#39;s time or reduce operator stress; kick back or other potential for injury is not reduced. 
         [0008]    There is no system that eliminates saw marks and chatter, the use of waxes, chipping, splitting, tear and blow out of the work piece. 
         [0009]    These systems do not dimension the wood as well as form it. Slightly over cut material is not accommodated. Existing systems do not have a unique indexing system that uses spacers or interfaces with other manufacturers gages for precision processing of materials. 
         [0010]    Many systems do not eliminate waste and improve the performance of the machine on which it is installed. 
         [0011]    These systems require a number of light passes to be made. The best feed rate is the slowest speed. 
         [0012]    From the above, it can be seen what is needed is a system and a process for installation of its major components, comprised of a clamping apparatus and adjustable back fence, for the precision processing of work pieces on a wood shaper, router table and table saw with a greater degree of operator ease, speed, safety, more economical and consistent results, as a clamping apparatus and back fence assembly. 
       SUMMARY OF THE INVENTION 
       [0013]    The present invention is a system and a process for installation of its major components, comprised of a clamping apparatus and adjustable back fence for precision processing of material on a wood shaper, a router table or a table saw. Typically these power tools are used in woodworking shops by professionals and amateurs. These tools are used to process other materials as well. As a result of the use of this system and its process for installation, material processing precision and operating conditions are greatly improved. 
         [0014]    In the preferred embodiment, the assembly features a portable platform universally adaptable to various types of wood shapers, router tables and table saws. The present invention, that is operator controlled, allows for loading and precision placement of a work piece in a controlled and flexible clamping environment. The machine operator is then able to move the work piece through the cutting operation in a positively engaged way with high visibility and with a greater degree of operator safety. The assembly features a back fence, indexing system and compatibility with other manufacturers equipment. The system is useable with power feeders as well as accommodating manual feeding.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0073]      FIG. 1  is a perspective view of the clamping apparatus assembly  10 . It is comprised of a platform base  12  made from 0.75 inch thick Mic 6 aluminum plate. The platform base  12  has a top  14 , a bottom  16 , a front  18 , a back  20 , a left side  22  and a right side  24 . The top  12  has mounted to it a material stop  52  held in place by general assembly round head machine screws  40 . Adjacent to the material stop  52  on the top surface  14  is applied a non slip surface film  48  such as that sold by the 3M Company of St. Paul, Minn. under the brand Safetywalk 3-10 Medium Resilient Tread Film. The bottom  16  of platform base  12  has applied to it a slip surface film  50  such as that sold by the Woodcraft Supply, LLC of Parkersburg, W. Va. under the brand UHMW Slick Strip. 
         [0074]    An overhead guide/guard  26  is made from clear poly carbonate sheet such as GE Brand Lexan. Oversized fastening holes are drilled to accommodate general assembly round head bolts  40  that fix the overhead guard/guide  26  to guide/guard risers  28 . This is done to accommodate final squaring and alignment with a processing machine fence guide  98 . Guide/guard risers are affixed to the top of platform base  12  by general assembly flat head machine screws  42  inserted through the bottom  16  of platform base  12 . 
         [0075]    A secondary riser support  57  is mounted to the platform base  12  with general assembly flat head machine screws  42  to support secondary handle  56 . 
         [0076]    Four clamp risers  46  are mounted to platform base  12  by general assembly flat head screws  42 . This is done to raise sacrifice stick clamp  44 , such as that sold by De-Sta-Co Company of Auburn Hills, Mich. under the brand #309U, to appropriate height. Sacrifice stick  60  is held in its place by sacrifice stick clamp  44 . The purpose of sacrifice stick  60  is to block in the work piece  58 . This serves two purposes. One is to hold in place one side of the work piece  58 . The second is to absorb pressure from any cutter it may encounter, such as wood shaper cutter  88 , router cutter  90  and table saw blade  92 . The work piece  58  is thus saved from break out and chipping by sacrifice stick  60 . 
         [0077]    The work piece  58  is held in place by large clamp  30  such as that sold by De-Sta-Co Company of Auburn Hills, Mich. under the brand #245U. The large clamp  30  is modified by the addition of a custom primary handle  54 . The large clamp  30  is mounted on large clamp riser block  32  by four screws  40 . Clamp riser block  32  is made from 0.75 inch thick 6061 aluminum plate and has four drilled and tapped holes in its upper surface to accommodate four screws  40 . A critical feature of large clamp block  32  is an approximately centrally located drilled and tapped hole in its bottom surface. This drilled and tapped hole accommodates clamp riser block flat head machine screw  38  that is a 0.5 inch×13×1.5 inch in size. This is a critical part of the assembly as the center line of screw  38  becomes the central pivot access of the entire component assembly, comprised of clamp  30 , block  32 , four screws  40  and the screw  38 . This entire assembly may be placed in any of the plurality of holes  100  drilled through platform base  12 . The adjustment holes  100  for block  36  are reamed to accommodate a plane surface  38   a , that is the underside of the head of clamp riser block screw  38 . Another key feature of the invention is, once clamp  30  is pivoted into its selected position, screw  38  is tightened to bear on surface  38   a . An amount of surface area  38   a  is needed to supply the critical binding force to secure and hold the placement of the components mentioned above. 
         [0078]    Another key feature of the invention is work piece block  62  that is comprised of ten plane surfaces, as shown in the drawings in the preferred embodiment, cut from UHMW Polypropylene (ultra high molecular weight) sheet material. A work block non slip top film  64  and a work block non slip bottom film  66  is applied respectively to work piece block  62 . Block  62  may have six or more surfaces, in various manufactures and accommodating various shaped work pieces  58 . Blocking of the work piece  58  can be accomplished by contact of block  62  on one, or two sides in the preferred embodiment, of the work piece  58 . In particular the block  62  or the work piece  58 , as chosen by the operator, is held in its place by medium clamp  34  such as that sold by De-Sta-Co Company of Auburn Hills, Mich. under the brand #237U, that is mounted at the opposite end of the clamping apparatus  10  respective to clamp  30 . 
         [0079]    The medium clamp  34  is mounted on medium clamp riser block  36  by four screws  40 . Block  36  is made from 0.75 inch thick 6061 aluminum plate and has four drilled and tapped holes in its upper surface to accommodate four screws  40 . A critical feature of block  36  is an approximately centrally located drilled and tapped hole in its bottom surface. This drilled and tapped hole accommodates screw  38  that is a 0.5 inch×13×1.5 inch in size. This is a critical part of the assembly as the center line of screw  38  becomes the central pivot access of the entire component assembly, comprised of clamp  34 , block  36 , screws  40  and the screw  38 . This entire assembly may be placed in any of the plurality of holes  100  drilled through platform base  12 . The adjustment holes  100  are reamed to accommodate a plane surface  38   a  that is the underside of screw  38 . This is another key feature of the invention, as once clamp  34  is pivoted into its selected position, screw  38  is tightened to bear on surface  38   a . This amount of surface area  38   a  is needed to supply the critical binding force to secure and hold the placement of the components mentioned above. 
         [0080]      FIG. 2  is a plan view of the clamping apparatus of  FIG. 1  and further shows the assembly configuration as described above. 
         [0081]      FIG. 3  is perspective view of a first embodiment assembly of the clamping apparatus of  FIG. 1 . This embodiment is smaller in its dimension and can also be made of lighter materials than are specified. The object of this first embodiment is to accommodate small processing machines such as are more commonly used by the amateur wood worker in a home environment.  FIG. 3  is a perspective view of the clamping apparatus assembly  10 ′. It is comprised of a platform base  12 ′ made from 0.75 inch thick Mic 6 aluminum plate.

This entire assembly may be placed in any of the plurality of holes  100 ′ drilled through platform base  12 ′. The holes  100 ′ are reamed to accommodate a plane surface  38   a ′, that is the underside of screw  38 ′. This is another key feature of the invention, as once clamp  30 ′ is pivoted into its selected position, screw  38 ′ is tightened to bear on surface  38   a ′. This amount of surface area  38   a ′ is needed to supply the critical binding force to secure and hold the placement of the components mentioned above. 
         [0087]    Another key feature of the invention is work piece block  62 ′ that is comprised of ten plane surfaces, as shown in the drawings in the preferred embodiment, cut from UHMW Polypropylene (ultra high molecular weight) sheet material. A work block non slip top film  64 ′ and a work block non slip bottom film  66 ′ is applied respectively to work piece block  62 ′.

         [0124]    In conclusion thus, the reader will see the Positioning System For Work Piece Milling and a process for installation of its major components, comprised of a clamping devise and adjustable back fence, for precision processing of material on a wood shaper, a router table and a table saw provides a highly reliable, light weight, yet heavy duty, economical device that can be used in a manual version by professionals and amateurs alike and can also be automated by any means possible to further enhance its efficiency. In fact great value is obtained from being able to stack and interchange a clamping apparatus  10 ,  10 ′ and a adjustable back fence assembly  112  to convert from cope cuts to pattern cuts. Great advantage is obtained in being able to switch easily between doing the cope and pattern cuts. This is done by mounting an entire set of cutters, typically six stacked onto the shaper spindle, all at the same time. Individual cutters are typically 1.250 inches in thickness. The cope clamping device has a base that is typically 1.290 inches in thickness. The work piece is mounted on this base. This allows for precision positioning of the work piece to perform the cope cut on the top cutters. The pattern cut is obtained by use of the back fence and the shaper table surface to engage the bottom cutters. With this system, once the cutters are installed, there is no need to move or adjust the cutters. Precision join able cope and pattern cuts are obtained by use of this system. 
         [0125]    While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment and a first embodiment thereof. Many other variations are possible such as additional numbers of clamps, plates, extrusions, automation, other proportional and dimensional configurations, various use of materials in construction, pluralities of work piece blocks, handles and knobs and installation on all types of processing equipment. 
         [0126]    Accordingly, the scope of the invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
