Definitions

  • This invention relates to a marking jig and relates particularly to a jig for marking a workpiece at desired angular locations and desired orientations.
  • markings it is often desired to mark a work piece with markings at predetermined angular positions.
  • the markings may be desired for subsequent work to be performed on the work piece or for the application of indicia or the like at those locations.
  • Marking templates have been proposed in which the number locations are predetermined. Such templates, however, are only useful for one particular type or size of clock face. A large number of different templates is therefore required for different types and sizes of clock faces. It is therefore desirable to provide a marking jig which facilitates the setting of a number of predetermined angular positions on a work face.
  • a marking jig particularly for marking the number positions for clock faces in which the position of the numbers is accurately determined irrespective of the shape of the clock face. It is also desirable to provide a marking jig in which the angular relationship of the points to be marked can be related to the angular position of those points around a centre.
  • clock face marking jig which is of simple construction and is quick and easy to use and which can be used for any type of clock face marking.
  • a marking jig comprising a base adapted to be engaged with a work piece to be marked, an arm adapted to engage with the base and be angularly movable relative thereto, locating means to locate the arm at one or more desired angular positions relative to the base and a set piece carried by the arm and by which a point is able to be set at a desired location relative to the base.
  • the marking jig is designed for the marking of relative positions of clock face numbers.
  • the arm is provided with twelve holes equally spaced about an axis from which the arm extends radially.
  • the base carries one or more locating pegs adapted to engage one or more of the holes in the arm. With this arrangement, the arm can be positioned at twelve different locations relative to the base, each location being 30° angularly spaced from each other.
  • the holes may be provided in the base and the locating pegs mounted on the arm.

  • the marking block assembly a screw clamp is used to clamp the marking block assembly at the desired radial distance from the center axis, and the block is provided with one or more holes through which punch marks, pencil marks or other markings may be made to the workpiece on which* the base is located.
  • a nail may be used as a punch to mark relatively soft materials such as wood while a pencil may be used to mark relatively hard materials such as metal, ceramic, stone, etc.

  • the base plate 12 is provided, in this embodiment, with three upstanding locating pegs 14. The pegs are accurately positioned around the edge of the base plate 12 so that the division arm 16 can be accurately located relative to the base plate 12.
  • the base plate 12 is provided with a centrally located hole 17 by which it is fastened to a workpiece 18, as shown in Figure 5, by means of a bolt extending through a shaft-receiving hole in the workpiece and a nut 19.
  • the arm 16 is mounted thereon.
  • the arm 16 includes a central boss portion 21 having a central aperture 22 of a size greater than the size of the nut 19. Twelve locating holes 23 are accurately located equally spaced around the boss portion 21 and equally distant from the aperture 22. The locating holes 23 are of a size to engage over the locating pegs 14 to thereby locate the division arm 16 on the base plate 12.
  • the arm portion 24 extends radially from the boss portion 21 and is provided with a slot 26.

  • the marking block assembly 27 and/or template 33 may be used to accurately locate and position the numbers around the workpiece 18. If using the assembly 27, punch marks or pencil marks, or the like 39 ( Figure 5) can be made to show the location of the numbers. If the workpiece is other than circular, such as square, the numbers can still be accurately located at the appropriate angular position by simply moving the marking assembly to the appropriate position along the arm portion 24.

This allows clock numbers to be placed, or marked radially on the workpiece by positioning the top, in the case of numbers 9 to 3, against the straight side 38 and, in the case of numbers 4 to 8, by placing the bottom of the number against the straight side 38.

  • the intervening numbers are then placed with the appropriate 30° or 60° angular marking 37 aligned on the arm portion 24 so as to provide a vertical straight edge 38 when the arm is appropriately positioned to the respective number positions.
  • the numbers may be marked on the workpiece in any suitable fashion, or may be provided in any suitable material and secured to the work piece by any suitable means, such as adhesive or the like.
  • the work face may be of any shape, and the numbers may be positioned at any desired radial distance.
  • the marking jig of the invention enables numbers to be positioned accurately relative to the clock face centre irrespective of the radial distance therefrom of the number.
  • numbers can be positioned on oval, square, or irregular shaped work pieces.
  • the division arm 16 is approximately 200mm long and the slot is 8mm wide. However, the division arm 16 may be made any length commensurate with intended use.
