the chain saw in order to assist in the placement of the
cutting element a predetermined distance from the end of a
log. The light beam element, such as a laser, is mounted to
the chain saw at a preselected angle relative to the cutting
plane. When the beam of light is on the end of the log or
cutting piece and the cut is made normal to the log, each cut
section is of equal length.
Representative independent claim 1 is reproduced as
follows:
1. A saw for cutting logs to preselected lengths,
comprising:
power-driven cutting means operable for cutting a log in
a cutting plane;
support means to which said cutting means are mounted; and
a light source secured to said support means, for
emitting a substantially non-expanding light beam at a
preselected angle relative to said cutting means.
