Definitions

  • the invention relates to devices for controlling linear movement of an object such as a fence on a table saw, particularly devices for connecting an auxiliary guide rail to a pre-existing fence rail.
  • Table saws may be equipped with a movable fence to allow an operator to set desired cut dimensions.
  • Table saw fences typically are movable along a rail that is bolted along one side of the table saw. An operator may slide the fence back and forth along the rail and then lock the fence in place by means of a locking handle. Many such table saws are sold in a design that requires manual adjustment of the fence.
  • an object of the invention is to provide an automated fence positioning system that is easy to install and to adapt to different table saw designs.
  • Another object of the invention is to produce a table saw control system that is less expensive to produce compared to prior control systems, without compromising speed, precision, and accuracy specifications.
  • the invention provides automated fence positioning systems that quickly and accurately reposition a fence in the course of executing a pre-determined cut or sequence of cuts on a table saw.
  • a preferred example of a linkage device for connecting an auxiliary guide rail to a table saw employs combinations of metal sheets. For example, a first set of sheets are configured for attachment to a positioner guide rail. A second set of sheets are selected for attachment to another object such as a fence rail. The two sets of sheets are then bolted together forming a robust versatile linkage device.
  • Figure 1 is a perspective view of an automated fence positioning system.
  • Figure 2 is a partial cross-sectional view of the system shown in Figure 1.
  • Figure 3 is a close-up view of a coupling device shown in Figure 2.
  • Figure 4 is a partially exploded view of a rail section and a carriage device configured to move inside the rail.
  • Figures 5 and 6 show side views of a bearing support member, without and with a bearing assembly, respectively.
  • Figures 7 and 8 show close-up details of Figures 5 and 6, respectively.
  • Figures 9 and 10 show side views of brackets used to couple, in parallel, a fence positioning rail to a fence guide rail.
  • Figures 11 and 12 are perspective views, exploded and assembled, respectively, of the coupling device shown in Figures 9 and 10.
  • Figure 13 is a perspective view of another linkage device. Description of Examples of the Invention The invention has numerous aspects and permutations in addition to the examples described below.
  • linkage devices include multiple layers of metal sheets sandwiched together. One or more sheets are configured for attachment to a positioner guide rail. One or more other sheets in the sandwich are configured for attachment to another structure such as a surface on a piece of equipment, for example, a table saw.
  • FIG 1 shows a perspective view of an exemplary fence control system 20.
  • Fence 22 is provided on a table saw to index a piece of material for cutting relative to saw blade 24.
  • Fence 22 is connected to fence support member 26 which is slidably connected to fence positioning rail 30.
  • Fence positioning rail 30 is coupled to positioning guide rail 34 via clamps or linkage devices 36a and 36b.
  • Carriage coupling device 40 rigidly connects fence support member 26 to a carriage (shown in Figures 2- 4) which moves inside positioning guide rail 34.
  • Screw member 42 is driven by belt and pulley assembly 44 and a motor inside housing 46 to move the carriage along with carriage coupling device 40, fence support member, and fence 22 to properly position materials for cutting.
  • FIG. 2 is a cross-sectional view through the assembly of Figure 1 showing the linkage between internal carriage 50 and carriage coupling device 40.
  • Carriage 50 has a cylindrical portion that has internal threads complimenting threads on screw shaft 42. The cylindrical portion of carriage 50 is contained entirely inside positioning guide rail 34.
  • Carriage 50 also has a flange portion 51 that extends through slot 52 and runs substantially the entire length of positioning guide rail 34.
  • Flange portion 51 includes three T-slots.
  • One T-slot has anti-friction surface material 54 so that carriage 50 can move with a low coefficient of friction relative to T-structure 55 on positioning guide rail 34. Two other T-slots are provided.
  • T-slot 56a receives one or more bolts for securing fence structure coupling device 40.
  • T-slot 56b receives one or more bolts for securing interlock plate member 57a.
  • Interlock device 57b is mounted on plate member 57a, and operates to prevent operation of the machine while the carriage is moving.
  • the T-slot configuration shown in Figure 3 provides a rigid, sturdy connection between carriage 50 and carriage coupling device 40, thus enabling carriage 50 to move smoothly on a single rail portion 55 without contacting any other internal surface inside positioning guide rail 34. Therefore, the positioning system can operate with significantly less friction making the device more efficient to operate and less expensive to produce compared to prior positioning systems.
  • Alternative slot arrangements may be used.
  • Other types of fastening devices for example, bolts with nuts, soldered or welded connections, etc. may also be used.
  • Carriage 50 includes cylindrical portion 60 connected to flange portion 51.
  • Flange portion 51 includes three T-slots 64, 66, and 68 for receiving T-structures, as discussed above and shown in Figure 3.
  • Collar members 72a and 72b are secured at opposite ends of carriage 50, and are provided with internal threads 74 complimenting external threads on screw 42.
  • Figures 5-8 illustrate a support device 80 for holding a bearing assembly 82.
  • Bearing support devices 80 may be used at opposite ends of positioning guide rail 34 to support screw 42 to permit driven rotation of screw 42.
  • Figure 5 shows bearing support device 80 without a bearing assembly.
  • a central hole 83 is provided in bearing support device 80 for receiving bearing assembly 82.
  • Longitudinal apertures 84 are provided around hole 83 to provide various potential advantages.
  • longitudinal apertures 84 may allow greater range of manufacturing tolerance for support device 80 and its ability to accommodate bearing assemblies of slightly varying dimension.
  • Apertures 84 may also provide some degree of bend or spring in cross-portions 88, thereby providing a clamping effect on the bearing assembly.
  • Figure 8 shows the original position of cross-portion 88 in dashed lines, and the slightly adjusted position of cross-portion 88 when securing bearing assembly 82.
  • FIGs 9-12 show different aspects of clamp or linkage device 36a.
  • clamp 36a includes four main pieces. Sheet pieces 100a and 100b are sandwiched between sheet pieces 102a and 102b. Sheet pieces 102a and 102b are configured for rigid attachment to positioning guide rail 34. All four pieces include holes 106 for bolting the sandwich together, as shown in Figure 12.
  • Figures 9 and 10 show that multiple holes 106 allow the position of sheet pieces 100a and 100b to be altered relative to sheet pieces 102a and 102b and the positioning guide rail to accommodate different fence positioning rail configurations.
  • External sheet pieces 102a and 102b may be attached to T-grooves in positioning guide rail 34 by T-bolt devices 110, as shown in Figure 2.
  • Figure 13 shows another linkage device 200.
  • Outer plate members 202 and 204 are configured for fastening to external T-slots in a cylindrical guide rail, for example, as previously described.
  • Inner plate members 206 and 208 have flanges 210 and 212 configured for attaching inner plate members 206 and 208 to a substantially planar surface in contrast to the cylindrical * surface of fence positioning rail 30.
  • standard outer plate members 202 and 204 may be used with different inner plate members to connect positioning guide rail 34 to different structures.
  • the invention may be implemented in numerous different machine configurations with varying levels of automation.
  • the invention may also be used to process many different kinds of materials including, but not limited to, wood, wood composites, polymeric materials such as PVC, polystyrene, polypropylene, polyethylene, fiberglass, textiles, etc.
  • the invention may be used to carry out other processing steps such as bonding, sewing, heating, UV curing, painting or graphics application, etc.
  • the subject matter of the invention includes all novel and nonobvious combinations and subcombinations of the various elements, features, functions, and/or properties disclosed herein.
