The first complete fret saw machine was made by H. L. Beach,
of Montrose, Pennsylvania. Motion was given to the saw by an
adjustable friction pulley on the crank shaft, and the speed
could be varied at will by the operator depressing the treadle.
The saw guides were adjustable laterally and transversely to
line, or to give any desired rake to the saw; the cross heads
were also adjustable for wear. Tension was given to the saw
by a ratchet gear. The working parts were suspended to a wrought-iron
tubular shaft, which was held in place by a box and lever, and
balanced by a spring. An adjustable steel bearing supported
the back of the saw, and it could also be used to hold down
the work. An air pump for removing the sawdust was attached
to the cross head.
Mr. W. J. Cunningham, of London, patented about 1865 a combined
fret saw and drilling machine, of very simple construction.
