| description | The present invention relates to sawing apparatus comprising a supporting base from which extend four uprights whose axes are at the vertices of a rectangle, a platform mounted for movement longitudinally of itself across said supporting base and between opposed pairs of said uprights, the platform being preferably mounted on rollers engageable with parallel rails supported on the supporting base, a cradle mounted for vertical sliding movement along said uprights and supporting in an underslung position, preferably to be orientable in a horizontal plane, a chain saw for sawing timber carried by said platform, and a head frame above said cradle, said frame including tubular members dimensioned and positioned to fit slidably about said uprights and being preferably braced where fitted about said uprights, first locking means to lock said head frame relative to said uprights, said head frame mounting means for adjusting the level above said platform of said cradle and hence of said chain saw, and second locking means for locking said cradle at its adjusted level relative to said uprights. Both the platform and the rails may be in interconnected lengths to enable both to be reduced in length appropriate to transport purposes. |
