Definitions

  • This invention relates to a chisel comprising a handle, a metal shaft projecting forwardly of the handle and a chisel blade on the front end of the shaft.
  • Such a chisel is well known for use in chiselling wood and similar material.
  • the chisel is characterised in that the blade is releasably clamped to the shaft so as to be replaceable.
  • the illustrated chisel 10 comprises a handle 11, a metal shaft 12 projecting forwardly of the handle 11 and a chisel blade 13 on the front end of the shaft 12.
  • the chisel blade 13 is releasably clamped to the shaft 12 so as to be replaceable.
  • the blade 13 is releasably clamped to the shaft 12 by an elongate springy member 14 which extends along the shaft 12, being pivotably connected to the shaft 12 by a pivot connection 15 closedly adjacent the blade 13, the pivot 15 taking the form of a rivet, as shown most clearly in Fig. 8.
  • the springiness of the member 14 is such that its front end 14a bears down strongly upon the blade 13 to clamp the blade 13 to the shaft 12, whilst the rear end 14b is biased downwardly into a recess lla in handle 11. To release the blade 13, the rear end 14b of member 14 is lifted out of the recess lla and member 14 is then pivoted about the pivot 15, as shown in Fig. 10.
  • the blade 13 is located on the shaft 12 by a spigot 12a of shaft 12 locating in a hole 13a in the blade 13, and by the pivot 15 locating in a notch 13b at the rear end of the blade 13, as well as the downward pressure of the front end 14a of member 14 when in its normal position as shown in Figs. 1 to 5 and 8.
  • the handle 11 has a cavity llb into which a spare blade holder 16 is releasably clipped by virtue of a small projection llc at the rear end of cavity llb locating in a recess 16a of the blade holder 16 and an integral spring arm 16b of blade holder 16 engaging the front end wall lld of cavity llb of handle 11.
  • the blade holder 16 can hold a number of blades 13c, 13d, for example, of different sizes.
  • One side 16c of the holder 16 is enlarged and seats correspondingly in the handle 11 as shown, so that the holder 16 can only be inserted in the handle 11 one way round as shown.
  • Fig. 11 shows a strip of blades 13e, all of the same size, with waste material between each pair of adjacent blades, whilst F ig. 12 shows six blades 13f to 13k of progressively increasing widths.
  • the chisel 10 can of course be used by anybody, and affords the advantage of the blade being replaceable either when it gets blunt or a different width blade is required, or it is desired to remove the blade during non-use for safety or convenience. It is believed that the "do-it-yourself" handyman in particular will find the chisel 10 useful.
