Improvements in Sawing Apparatus for Use in the Manufacture of
Barrels, Casks, and the like.
We, ANTHON BERNHARD ELIAS NILSEN and HAAKEN LARPENT MATHIESEN, both
of Fredriksstad, in the Kingdom of Norway, Millowners do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:—
This invention relates to sawing machinery for cutting the bottoms or ends of
barrels, casks and the like, and has for its object to cut around the whole periphery
of each end at once with a saw-blade bent into the form of a circle instead of sawing
round the periphery with a vertically moving saw, whereby such ends are cut much
more quickly and exactly than heretofore.
According to our said invention the saw-blade is fixed around a rotating wheel of
the same size as the ends or bottoms required, the plane of which wheel is parallel to
the material from which the bottom or end is to be cut.
In the accompanying drawing figure 1 is a side elevation of apparatus constructed
according to this invention, and
Figure 2 is a plan of the same.
Figure 3 is an elevation partly in section and drawn to an enlarged scale of the
saw-wheel.
a is a stand or frame which is secured to a wall or other support and in which is
mounted a vertically rotating spindle or shaft carrying at its lower end a horizontal
wheel c upon the periphery of which the saw-blade d is fastened by screws or other
suitable means. The frame also carries a support for the material from which the
ends are cut.
The spindle is driven through the medium of a pulley e and is raised or lowered
by means of a screw and the gearing 9 which is operated by the wheel h. To
prevent the screw from turning with the spindle a fork i is provided.
The wheel c is of the same diameter externally as the bottom or ends to be cut,
and has fixed within it knives or cutters k adapted to cut the edge of the end
obliquely.

page_text: The
The wood to be cut is placed under the saw upon the sledge or carriage and is
held firmly thereon by the ring m which encircles the saw-wheel and is pressed
against the wood by means of levers n which are operated by the treadle o.
ring is raised by means of the counter-weight p. The said ring is guided by two
guides placed on the stand or support.
q
Below the saw is placed a long table or staging r which on each side exceeds
somewhat beyond the frame.
Two sledges or carriages are provided on which the wood is laid and which are
alternately pushed under the saw.
When the carriage with the wood thereon is placed under the saw-wheel, the
workman depresses the treadle o whereby the ring m is caused to press on the wood
and hold the same firmly on the carriage. As the saw rotates the workman turns
the wheel h to cause the saw to descend to pass through the wood.
When the wood is cut through the ring m is raised, the saw is drawn up by the
wheel and the carriage is moved to one side to receive a fresh supply of wood while
the carriage standing on the other side is brought under the saw and the operation is
repeated.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In sawing apparatus for cutting out the ends of barrels, casks and the like, the
arrangement of the saw blade upon the periphery of a wheel the plane of which is
parallel to the material to be cut substantially as described.
2. In sawing apparatus of the class described in the preceding claiming clause the
arrangement of one or more knives for cutting the edges of the ends or bottoms
obliquely.
3. The improved apparatus constructed and arranged substantially as hereinbefore
described with reference to the accompanying drawing.
