Definitions

  • the path of travel of the engraving tool is either controlled by the movement of a stylus or follower over a master pattern corresponding-to the shape to be engraved, often through the intermediary of a pantograph mechanism, ortelse the path of the engraving tool may be controlled in accordance with data derived from a data processor.
  • the width of an engraved line so formed depends on the cutting width or tip size of the engraving tool employed.
  • a holder for an engraving tool including a body having means for attachment to the rotatable drive of an engraving machine and a tool holding member displaceable relative to the body such that an engraving tool carried thereby can be moved between a position in which the cutting tip of the tool lies on the axis of rotation of the tool holder to a position in which the cutting tip of the tool is displaced from said axis of rotation of the tool holder.
  • the tool is arranged for translational displacement relative to the axis of rotation of the tool holder.
  • the invention provides a holder for an engraving tool including a body having means for attachment to the rotatable drive of an engraving machine and a tool holding member slideable along an axis transverse to the axis of rotation of the tool holder, said tool holding member having a location for receiving the shank of an engraving tool and being slideable such that the tool can be moved translationally from a position in which it lies along the axis of rotation of the tool holder to a position to one side of said axis, and vice versa, and means for retaining the tool in an adjusted position.
  • the tool is mounted so that it can be rotated about an axis normal to the axis of rotation of the tool holder.
  • the invention therefore also provides a holder for an engraving tool including a body having means for attachment to the rotatable drive of an engraving machine and a bore receiving a tool holding member rotatable through an angle about an axis normal to the axis of rotation of the tool holder, said tool holding member having a location for receiving the shank of an engraving tool such that by rotation of the tool holding member, the tool can either be caused to lie along the axis of rotation of the tool holder or at an angle thereto, and means for retaining the tool in an adjusted position.
  • the body of the holder is preferably provided with a shank to fit in the chuck of an engraving machine.
  • the means for retaining the tool in an adjusted position may comprise two set screws arranged at diametrically opposite sides of the tool and engageable with the shank of the tool. By appropriate advancing and retraction of the two set screws, the shank of the tool and hence its tip can be displaced towards and away from the axis of rotation of the tool holder and maintained in any desired position within the possible range of movement.
  • a further set screw may be provided for securing the shank of the tool relative to the tool holding member.
  • the engraving tool holder shown in this embodiment is intended to permit translational displacement of an engraving tool relative to the axis of rotation of the tool holder.
  • the device comprises a cylindrical body 1 having a shank 2 for fitting in the chuck of an engraving machine.
  • the body 1 is provided with a cylindrical diametric bore 3 adjacent its lower end in which can slide with a close fit a correspondingly shaped cylindrical bar 4, forming a tool.holding member, having a bore 5 for locating the shank 6a of an engraving tool 6.
  • a set screw 7 located in a threaded axial passage in the bar 4 is provided for locking the tool 6 in position in the bore 5.
  • the upper end 6b of the shank of the tool 6 extends beyond the bar 4 and is accommodated in an elongated offset recess 8 in the body 1.
  • Two diametrically spaced set screws 9 are located in threaded bores provided in the body 1 above the bore 3 but parallel thereto, such that the set screws can engage the upper end 6b of the shank of the tool 6.
  • the shank 6b of the tool 6 can be moved between a position in which the tip of the tool lies on the axis of rotation of the tool holder and any of many positions in which the tip-of the tool 6 is translationally displaced from this axis, within the range of adjustment permitted by the length of the elliptical recess 8.
  • the tool holding member 4 obviously slides to and fro in the bore 3 as the shank 6b of the tool is moved by the set screws 9.
  • the set screws also serve to lock the tool 6 in an adjusted position.
  • the engraving tool holder shown in this embodiment is intended to permit rotation of the tool about a horizontal axis normal to the vertical axis of rotation of the tool holder.
  • the device comprises a cylindrical body 11 having a shank 12 for fitting in the chuck of an engraving machine.
  • the body is provided with a diametrically extending cylindrical bore 13 which receives a corresponding dimensioned cylindrical tool holding member 14 having a cross hole 15 to receive the shank 16a of an engraving tool 16.
  • the tool shank is held in position in the hole 15 by a set screw 17 extending axially of the cylindrical member 14.
  • the tool 16 extends through an appropriately aligned elongated aperture 18 in the lower end of the tool holder 11 so that rotation of the cylindrical tool holding member 14 about its axis causes the tip of the tool 16 to move between a position along the axis of rotation of the tool holder (shown in full lines in Figure 4) and any of many positions displaced from this axis (as shown in broken lines in Figure 4), within the range of adjustment permitted by the elongated aperture 18.
  • This adjustment is achieved by means of two diametrically spaced set screws 19 located in threaded bores in the body 11 below the bore 13 and at right angles thereto. These set screws are respectively retracted and advanced until the tip of the tool 16 is at the desired position and.are then locked against the shank of the tool to hold it in the adjusted position.
  • the tip of the tool when the tip of the tool is displaced from the axis of rotation of the tool holder the tip of the tool will describe a circular locus which consequently increases the width of the groove cut in a workpiece to be engraved, the magnitude of this increase in width being dependent on the amount of displacement of the tool tip from the axis of rotation of the tool holder.
  • the tool holder according to the present invention provides in particular the following advantages:-
