Definitions

  • This invention relates to manually actuable combination tools, comprising a base plate and a two part metal working device, one part of which is presented by the base plate and the other part is displaceable relative to the base plate via a hand lever.
  • Manually actuable tools each capable of performing a single metal working operation are well known in the art.
  • a manually operable combination tool is disclosed in GB-A-1,066,274 but this disclosure proposes different manual actuating levers for actuating different metal working devices.
  • a device comprising manually actuable tools is also known from FR-A-2,361,982 in which several tools are operated by a single actuating lever, but the operating mechanism itself somewhat limits the number and form of the tools that can be provided.
  • the invention as claimed is intended to provide an efficacious remedy to the prior art requirement of a plurality of separate tools. It provides a combination tool comprising a base plate, a drive member pivotally attached to the base plate, a plurality of two-part metal working devices each having one part presented by the base plate and the other part presented by said drive member, and a single hand lever; the drive member being rotatable relative to the base plate by the single hand lever to effect simultaneous displacement of all the parts of said metal working devices presented by the drive member relative to their co-opreating parts presented by the base plate, the hand lever being pivotally attached to said base plate; characterised in that the hand lever includes a cam presenting an edge cam profile, eccentric to the rotational axis of the hand lever, engaged with the drive member, the axis of said cam being spaced from the pivotal axis of the drive member.
  • the advantage offered by the invention is that a single combination tool can perform a wide range of metal working operations in response to displacement of a single lever, and in view of this and its modest cost, it is of particular advantage to the amateur metal worker.
  • the base plate is supported by a frame so as to be pivotally displaceable between two positions substantially at right angles to one another.
  • the base plate presents guides for a slide element and said slide element is linked to said drive member, for reciprocation in response to oscillation of said drive member, and said slide element presents one part of a metal working device whilst the base plate presents the other part of the device.
  • one, or both, parts of selected metal working devices are replaceable by a part or parts of other metal working devices whereby to increase the metal working operations performable by the tool.
  • Such interchanging of devices can greatly increase the versitility of the tool.
  • the base plate and/or the drive member is adapted to have at least one metal working device attached thereto co-operable with other working devices of the tool to increase the range of metal working operations performable by the tool.
  • the tool preferably provides devices for performing such common metal working operations as shearing, notching, punching, rolling, and bending, on metal in strip, bar or rod form.
  • the tool includes device elements for scroll work conveniently by providing a pivot pin from the base plate and a peg presented by the slide member, the pivot pin serving to support a manually rotatable lever which presents an arcuate member, rigid with said lever and having a peripheral curvature increasing in radius from a slot-like opening intended to receive one end of a metal strip, rod or wire therein.
  • a second arcuate member is pivotally attached at one end to that end of said first arcuate member defining the periphery of the greatest radius and, in that position for said second segment closest to the pivotal axis for the manually rotatable lever, said second segment present a periphery which increases in radius from the pivotal connection with the first segment in such manner that said two segments, in combination, present a periphery gradually increasing in radius away from said slot-like opening.
  • a third arcuate member is pivotally attached at one end to that end of the second member most remote from the first member and, when in its closest position to the axis of the manually rotatable lever, the third arcuate member presents a periphery which increases in radius from that end attached to the second segment in a manner such that the three arcuate members, in combination, present a substantially continuous periphery which increases in radius towards the free end of the third segment.
  • arcuate members are detachably secured together and are interchangeable with other arcuate members of different curvatures.
  • a base plate in the example illustrated in Figs. 1, 2, 3, 4 and 5, a base plate, generally indicated by reference numeral 11, comprises a tool supporting part 11 a with a base part 11 & substantially at right angles thereto.
  • the base part 11 b conveniently includes two countersunk holes 12 and 13, by which the base may be secured to a work table.
  • the base part 11b also includes two upstanding lugs 14 and 15, with axially aligned bores 14a and 15a, by which the base plate 11 may be supported by a support arrangement, to be described hereinafter, as an alternative arrangement to the securement by screws through holes 12 and 13.
  • the base part 11 a includes a bore 1 6 and a drive member 17 is pivotally attached to part 11 a by a screw 18 which passes through a bore 19 in drive member 17 and through bore 16, the screw 18 being secured by a nut 20 on the reverse side of part 1 a.
  • the part 11 a includes an opening 21 therethrough and the part 11 a below opening 21, as viewed in Fig. 1, is deflected away from the plane of the illustrated face to house a shearing block 22 so that the face of block 22 exposed at the illustrated face of part 11 a lies in the plane of said face.
  • the block 22 is secured by screws 23 and 24 entering into tapped holes 25 and 26 respectively in part 11 a.
  • That part of drive member 17 intended to sweep a path adjacent the shearing block 22 has a configuration (not shown) which co-operates with the shearing block 22 to shear a metal strip or wire passing through the opening 21 when the drive member 17 is rotated anticlockwise as viewed in Fig. 1.
  • the tool affords means for shearing metal in wire, rod, or strip form.
  • the part 1 a further includes a section, generally identified by reference numeral 27, deflected away from the plane of the illustrated face to partially house a die 28 which is secured to part 11 a by two screws 29 and 30 which pass through bores in die 28 and enter respectively into tapped bores 31 and 32 in deflected part 27.
  • the die 28 has a bore 28a passing transversely therethrough and a vertical slot 28b, extending from the upper surface of the die block downwardly some distance below the axis of the bore 28a.
  • a punch 33 attached to a yoke 34, is slidably displaceable in bore 28a and the yoke 34 is secured to drive member 17 by a pivot screw 35 which passes through holes 34a in the two arms of the yoke and through a bore 36 in the drive member 17 in such manner that the two arms of the yoke embrace drive member 17.
  • the punch 33 is advanced along bore 28a and can punch a hole through the thickness of a metal strip or plate entered into the slot 28b.
  • the part 11 a includes a slot 37 into which that arm of yoke 34 engaging the side of the drive member 17 adjacent part 11 a can project so that the part 11 a does not interfere with the movement of yoke 34.
  • the part 11 a further includes a tapped bore 38 by which a platform element 39 may be attached to part 11 a by a screw 40 which passes through a slot 39a in element 39.
  • the element 39 has an open slot intended to receive the die 28 therein so that element 39 can support a metal strip or plate entered into the slot 28b of die 28 and the supporting surface of element 39 can be vertically adjusted to any desired plane below the axis of bore 28a.
  • the tool provides a punch device for punching holes in metal sheet or strip.
  • the drive member 17 is displaced by manually actuated mechanism, generally indicated by reference numeral 41, comprising a hand lever 42 with an annular flange 43, an eccentric 44, and a spindle 45 integral therewith.
  • the spindle 45 passes through a slot opening 46 in drive member 17 and through a bore 47 in the part 11 a, the free end of spindle 45 being threaded and captive by a nut 48. With the spindle 45 entered into bore 47 and secured by nut 48 the eccentric 44 lies in the slot 46.
  • the flange 43 has a diameter greater than the width of slot 46 whereupon flange 43 assists in retaining drive member 17 in close relationship with part 11 a.
  • the part 11 a includes a vertical slot 49 and, on the reverse face from that illustrated in Fig. 1 (see Fig. 4) a guide element, generally indicated by reference numeral 50, is secured to the part 11 a by screws 51, 52, 53 and 54.
  • the guide element is of generally U-shaped configuration comprising parallel limbs 55 and 56 and a bridge part 57, and the upper free ends of the limbs 55 and 56 are connected by a bridge piece 58.
  • the distance between the limbs 55 and 56 is greater than the width of the slot 49, the element 50 is secured to part 11 a so that the slot 49 opens between the limbs 55 and 56, and a slide element 59 is slidably disposed between the two limbs 55 and 56 whilst abutting the face of part 1 a a surrounding the slot 49.
  • a pin 60 passes through a slot 61 in drive member 17 and through the slot 49 for securement, as by threaded engagement, with the slide element 59 whereupon, pivotal displacement of the drive member 17 effects linear displacement of the slide element 59 within the guide element 50.
  • An anvil 62 is screwed into a tapped bore 63 in the bridge part 57 and a hammer 64 is screwed into a tapped bore 65 in the slide element 59 so that, when drive member 17 is rotated in an anticlockwise direction, as viewed in Fig. 1, the slide element 59 is downwardly displaced within the guide element 50 and the hammer 64 approaches anvil 62 and can caulk the head of a rivet between anvil 62 and hammer 64, the axis of the rivet lying in a plane passing through the axis of the anvil 62 and hammer 64.
  • the tool provides a device for riveting.
  • the slide element 59 also has a bending block 66 secured thereto by a screw 67 engaged in a tapped bore 68 in element 59, a roller 69 is mounted on a screw 70 secured in a tapped bore 71 in limb 55, and a roller 72 is mounted on a screw 73 secured in a tapped bore 74 in limb 56.
  • the plane passing through the axes of rollers 69 and 72 lies at right angles to the axis of the slide element 59 and thus, by rotating drive member 17 anticlockwise as viewed in Fig. 1, the bending block 66 may be advanced against a strip of wire or plate resting on the rollers 69 and 72 to cause said strip to bend.
  • the bending block 66 is of cube-like configuration arranged with a plane passing through two opposite corners parallel to the longitudinal direction of the slide element 59 so that the block presents a corner to a wire or plate resting on the rollers 69 and 72 to effect a sharp right angle bend to said wire or strip.
  • the bending block 66 may be interchangeable with bending blocks of other form so as to provide, for example, a bend in the wire or plate of desired curvature.
  • the tool provides means for bending a metal wire rod or plate.
  • the screw 67 is removed, to allow the bending block 66 to be removed, and a knurled roller 75, secured on a hand lever 76, is attached to slide element 59 by the screw 67 which passes, with clearance, through a bore 77 concentric with roller 75 before entering into threaded engagement with the bore 68 in slide element 59.
  • the knurled roller 75 is rotated about the axis of screw 67.
  • the drive member 17 can be pivotally rotated anticlockwise as viewed in Fig. 1 to lower slide element 59 and thereby engage the knurled rollers 75 with said wire, rod, or strip and, by further advancing the drive member 17 and knurled roller 75 will deflect the wire, rod or bar between rollers 69 and 72 and, by then rotating hand lever 76, a desired curvature can be imparted along the length of the metal wire, rod or bar.
  • the tool provides means for imparting a curvature along the length of a metal wire, rod or bar.
  • the mechanism illustrated in Fig. 7 allows a further operation to be performed and, as will be noted, said mechanism comprises a hand lever 78 with an arcuate section 79 secured thereto, a second arcuate section 80 pivotally attached to the free end of the first section 79, and a third arcuate section 81 pivotally attached to that end of the second section 80 remote from the first section 79.
  • the first section 79 presents an abutment face 79a engageable with and abutment face 80a presented by the second section 80 to limit clockwise displacement of the second section 80 relative to the first section 79
  • the second section 80 presents an abutment face 80b engageable with an abutment face 81 a on the third section 81 to limit clockwise displacement of the third section 81 relative to the second section 80.
  • the first section 79 includes a slot opening 82 and, when the faces 79a, and 80a and faces 80b and 81 a are in abutting relationship, the sections 79, 80 and 81 present peripheral surfaces 79b, 80c and 81 b defining a curvature of increasing radius from the slot 82 towards the free end of element 81 with respect to the axis of a bore 83 passing through the hand lever 78 and the section 69.
  • the mechanism illustrated in Fig. 7 and described above is attached to the tool by removing the anvil 62 and entering a long screw (not shown) through the bore 83 and into the threaded bore 63 in bridge part 57, the long screw allowing the sections 79, 80 and 81 to lie in planes outwardly of the plane passing through the free ends of rollers 69 and 70.
  • the screw 67 is also removed, to release the bending block 66, and a peg 84 is screwed into the threaded bore 68 in slide element 59 and has such length as to be outstanding from that plane passing through the free ends of rollers 69 and 70.
  • section 80 can be rotated anticlockwise (as viewed in Fig. 7) relative to section 79 and section 81 can be rotated anticlockwise relative to section 80 (as viewed in Fig. 1) to allow one end of a metal wire, rod, or bar 85 to be entered into the slot 82 when, by rotating the lever 78 anticlockwise (as viewed in Fig. 7) the wire, rod or strip 85 abuts the peg 84, whereupon further anticlockwise rotation of hand lever 79 causes the wire, rod or bar 85 to be progressively wound onto the peripheral surfaces 79b, 80c and 81 b, thus to produce a spiral form.
  • sections 79, 80 and 81 may be detachably connected together to permit one or more of said sections to be interchanged with sections of different peripheral surfaces, whereupon windings of different configurations can be obtained.
  • Figs. 8 and 9 show a support arrangement for the base plate 11, said arrangement comprising a base member 86 with its ends 87 and 88 deflected through 90° to receive the part 11b therebetween.
  • a bore 89 passes through both ends 87 and 88 and a pivot pin 90 passes through the bore 89 and through the bores 14a and 15a of part 11 b, thus to pivotally retain base plate 11 with the support 86, 87, 88.
  • the base member also has two bars 91 and 92 welded thereto and bent to channel form and screw elements 93 and 94 pass through the free end limbs 91 a and 92a of bars 91 and 92 and whereby the support arrangement can be mounted on the edge of the work bench by entering the edge of the work bench into the channel form of bars 91 and 92 and tensioning the screw elements 93 and 94 to frictionally engage the bench edge.
  • the end 87 has a bore 95 therethrough so that, when the base plate 11 is displaced to the position shown in Fig. 8, a pin or bolt (not shown) located in bore 95 will retain the base plate 11 in the illustrated position.
