Definitions

  • This invention relates to a combined tool jig and work table apparatus for mounting portable power tools, designed to be releasibly attachable to independent means of support, including proprietary work benches, prepared horizontal work surfaces or vertical support walls.
  • a number of free standing work benches and independent work tables allow for the attachment of portable power tools.
  • An example is the well known work bench described in GB-A-1267032 to which can be attached tooling jigs or small work tables supporting portable power tools.
  • the well known work bench described in GB-A-1267032 has been further modified to receive a work table on which certain power tools can be mounted (see EP-A-86307471.2).
  • a combined tooling jig and work table apparatus comprising a work table portion, a tool sole plate portion having an upper surface coplanar with the upper surface of the work table portion, openings in said sole plate portion, means to mount a power tool below said sole plate portion, with a cutter thereof extending upwardly through one of said openings and mounting means to mount said apparatus on a support structure whereby at least the sole plate portion is cantilevered out beyond said support structure, to allow said power tool to be mounted therebelow.
  • the structure of the present invention enables the combined tooling jig and work table apparatus to be attached to any suitable horizontal or vertical surface.
  • the mounting means may comprise holes formed in the work table portion which is suitable for the passage of screws to secure the work table portion to a horizontal support.
  • these holes may be used for the passage of bolts threaded into support blocks adapted to be clamped between the vice jaws of a work bench.
  • the mounting means comprises a support bar adapted to be secured to a wall, holding means to hold the edge of the work table portion remote from the sole plate portion to said support bar, a pair of brackets each adapted to be secured to the wall, below said support bar, a pair of bracing arms each extending upwardly at an acute angle to said wall from a separate one of said brackets and means securing said bracing arms to said brackets and to said apparatus at or adjacent the support plate portion.
  • the work table portion and the sole plate portion are both mounted between two elongate support members.
  • Such an arrangement enables the sole plate to be provided with means enabling it to be readily demounted from the support members, whereby the sole plate may be changed for another, to suit another power tool, and/or reversed temporarily to facilitate mounting of the power tool.
  • the apparatus further comprises a fence which can be slidably and adjustably mounted on said apparatus to guide an edge of a work piece as it is moved past the cutter of the power tool.
  • the fence is of a length to overlie the support members, the fence comprising two pairs of holes, one pair at each end, two generally U-shaped clamping brackets being arranged to have one arm of the U engaged in one of said holes, bolts passing through openings in the web of the U and the other arm of the U engaging under the respective support member, whereby tightening of said bolts will clamp the fence in a desired position.
  • the fence may include a sub-fence adjustably mounted thereon.
  • the apparatus is preferably provided with a template which may be used, for example, when the sole plate is reversed for the purpose of mounting the power tool.
  • the combined tooling jig and work table apparatus illustrated in Figure 1 comprises two angle section supports 10 having mounted therebetween a rectangular work table member 12 desirably made of medium density fibre board and a rectangular pressed steel tool sole plate 14, having its upper surface coplanar with the upper surface of member 12.
  • a rectangular work table member 12 desirably made of medium density fibre board
  • a rectangular pressed steel tool sole plate 14 having its upper surface coplanar with the upper surface of member 12.
  • self tapping screws 16 are provided in order to secure the work table member 12 in place against the vertical arms of the angle section support members 10.
  • self adhesive printed rules 18 Adjacent the upper surface of the work table member, on the upper surfaces of the horizontal arms of the angle section support members 10 are provided self adhesive printed rules 18 which could alternatively be screen printed.
  • the tool sole plate 14 is removably secured to the angle section support members 10 by nylon machine screws 20 permanently located in the support members 10 by means of hank bushes 22 set in the support member 10 and hank bushes 24 set in the sole plate 14 at appropriately disposed positions.
  • the act of mounting a portable power tool on the sole plate may be facilitated by the use of a hardboard template (not shown) interposed between the nylon machine screws and the underside of the sole plate.
  • Figure 1 shows the medium density fibre board work table member 12 provided with four 20mm diameter holes 28 designed to accommodate static vice pegs of the type used with the work bench of GB-A-1267032.
  • a further hole 28A is provided to enable a vertical steel column which may be used to mount a drill stand for vertical drilling, whilst the same hole is used to locate a support bar used for jig and fret-saw work as will be described later with reference to Figure 9.
  • the fibre board work table member 12 is also provided with four 6mm counter-sunk holes 29 which are used to locate self tapping screws (not shown) for securing the tooling jig either to the work bench of GB-A-1267032 or to a prepared horizontal work surface as illustrated in Figure 6.
  • a rebated channel 30 locates a fence (not shown) adjustable from 0 to 180° and is used for mitring and cross-cutting.
  • the removable steel tool sole plate 14 contains four punched and swaged holes 31, and a circular punched and swaged hole 32 having a punched location slot 33. These, together with the 6mm machine screws, nuts, washers and clamps which will be described later, are used to locate a large range of portable tools.
  • the sole plate 40 illustrated in Figure 2A includes a rectangular cut-out 45, two pairs of swaged slots 46 (more may be provided if desired), a cut-out 47 for locating a spreader/riving knife and a counter-sunk hole 48.
  • the plate 50 illustrated in Figure 2B comprises a central cut-out 51 and several counter-sunk holes 52 provided to suit a range of portable planers.
  • the plate 45 is used as the tool sole plate here and this is used together with a portable saw 60 in which the saw blade 61 is shown projecting upwardly through the slot 45.
  • Figure 4 illustrates the sole plate 40 of Figure 2A again, used in conjunction with a spreader/riving knife 63 which is allowed to protrude through the slot 47, having been secured to the sole plate 40 by means of a counter-sunk machine screw, nut and washer fitted into the hole 48.
  • the spreader/riving knife 63 supports a safety guard 65 and the knife itself is used to prevent the two parts of the cut work piece behind the saw from closing towards one another.
  • FIG. 5 one method of mounting the combined tooling jig and work table apparatus of the invention is illustrated.
  • the apparatus is used with the work bench 69 of GB-A-1267032 shown in Figure 3, this work bench 69 having the conventional clamping jaws 70,71 movable towards and away from one another by operation of handles 72 having threaded rods (not shown) associated therewith.
  • the jaws 70 and 71 are opened and then closed again to clamp two inverted T-shaped blocks 73 which are secured to the bottom of the work table member 12 by means of two counter-sunk screws 74 passing through the holes 29 illustrated in Figures 1 and 3.
  • the vice members of the work bench of GB-A-1267032 are first fully opened and the tooling jig assembly lowered into position so that the blocks 73 are placed between the vice members. These are then tightened, thereby clamping the assembly to the upper surface of the vice members 70,71. A slight chamfer on the upper faces of the arms 75,76 ensures that the tooling jig sits closely against the upper surfaces of the vice members of the work bench.
  • FIG. 6 An alternative arrangement is shown in Figure 6 in which the tooling jig is secured to a prepared horizontal surface, such as a work bench, using four counter-sunk self tapping screws (not shown) secured firmly into pre-drilled guide holes in the horizontal work surface 80.
  • a guide fence is illustrated in Figures 7 and 10 and includes a main elongate body member 92, preferably made from machined medium density fibre board, this having a semi-circular cut-out area 94, two through holes 95 and two blind holes 96. These holes are used in conjunction with clamping brackets 97 of modified U-shape having a web 98 and a shorter arm 99 and a longer arm 100 terminating in a small projection 101.
  • the web 98 has an elongate slot 102 through which is passed a coach bolt 103 having a thumb nut 104 threaded thereon.
  • the shorter arm 99 is used to engage under the horizontal arm of the angle section support member 10 on one side and the projection 101 on the longer arm is engaged in the blind hole 96. When the thumb nut 104 is tightened up this will urge the shorter arm 99 against the bottom of the horizontal arm of the support member 10 thereby holding the fence in place. This can be used to guide a work piece at an appropriate angle relative to the tool.
  • a safety guard 107 clamped to the top of the fence and covering the cutter of the power tool, which, in use, will be positioned in the cut out area 94.
  • the safety guard is preferably made of a transparent material, such as that sold under the trade mark "Perspex”.
  • Figure 10 shows the top face of the fence 92 with the through holes 95 and the cut-out area 94.
  • a sub-fence 122 made desirably from extruded aluminium, is shown together with two drilled holes in the fence 92 in which are placed tapped inserts 115.
  • the angled section sub-fence 122 is placed over the fence 92 with the cut-out pieces 54 immediately above the inserts 115.
  • the sub-fence 112 is then clamped upon the main fence 92 by means of thumb screws 126.
  • the fence 92 is indexed by reference to the printed rules 18 affixed to or printed on the surfaces of the two angle section support members 10. The fence is then used to guide the edge of the work piece relative to the tool mounted on the sole plate 14.
  • Figures 8 and 9 show a second embodiment in which a channel section mounting member 110 is secured to a wall surface 112 of a building at a location above a pair of fixing brackets 114.
  • the assembly illustrated in Figure 1 is mounted on the channel section support mounting member 110 by means of two quick release screws 116 and two supporting arms 118, which are made from tubular steel and crimped at their ends to aid fixing.
  • the supporting arms are mounted on fixing brackets 114 by screws and wing nuts 120 and extend upwardly at an acute angle to wall 112, with their upper ends secured to the angle section support members 10 by means of threaded studs 122 welded in a vertical plane to the support members 10.
  • the supporting bars 118 are secured in position by small wing nuts with washers threaded onto these threaded studs 122.
  • a machine tool 124 which, in this instance, is illustrated as a jig saw with a modified blade 126 designed for attachment (not shown in detail) to a sprung over-arm 128 which maintains the cutting blade 126 under tension.
  • the jig saw reciprocates vertically, permanently under tension and is prevented from side-ways movement to ensure cutting precision.
  • the assembly of the work table portion 12 and the sole plate portion 14,40,50 are readily mountable on a support, such as the work benches illustrated in Figures 3 and 6, or the wall illustrated in Figures 8 and 9, so that the assembly is cantilevered out from this support enabling easy mounting of a machine tool and easy operation thereof in use on a work piece.
