SAMUEL WRIGHT of Harriston, County of Wellington, Province of Ontario,
Dominion of Canada. "IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE
USED IN THE MANUFACTURE OF CASKS OR BARRELS."
The Invention has reference to machinery or apparatus for cutting staves for casks
or barrels.
In a machine for this purpose wherein a stave or staves may be cut to the size
and bevel required for a given diameter or size of cask or barrel, I provide according
to one arrangement, a pair of circular saws, so arranged on separate shafts or spindles,
that they may be placed at the required angle to cut the sides of staves to the
proper shape. One saw shaft or spindle is carried in suitable pedestals formed with
or attached to a frame or table and held in position so as not to move end ways in
the direction of the shaft or spindlo. The other saw shaft or spindle is carried in
pedes: als which are formed with or attached to a sliding carriage which is guided
so as to nove in a line by guides or grooves formed in the table or frame; the sliding
saw shaft or spindle fixing is coupled to a hand wheel and screw, or a hand lever
working on a toothed rack or bar, and is made to approach or recede from the fixed
Enw as may be required for the width of stave to be treated. The two saws are
placed opposite to each other with a sufficient space between them for the width of
staves to be cut, and are set at the necessary angle to suit the width and diameter
of barrel the staves are intended for; that is to say, the shafts or spindles are not
arranged with their axes in a common right line, but those ends to which the saws
are secured are somewhat raised to bring the saws into the proper respective planes
to form the bevels on the edges of the staves. The saw shafts or spindles are driven
by straps or other gearing from a countershaft suitably fixed it may be to the tables
or frames or other structure. Between the two saw tables or frames may be placed
a suitable frame or table, capable of being moved endways, and sliding in grooves
or guides or on antifriction wheels or in any other convenient way. The upper
surface of the sliding table is rounded to radii corresponding to the interior of the
bulge barrel for which the staves are intended, one end may be provided with a
stop or recess into which one end of the stave to be cut is placed, the other end of
the stave is then sufficiently pressed down on to the rounded table and by an

page_text: eccentric, cam or other suitable means held tightly down in position until the stave
has passed between the Raws.
Thus it will be seen that the saws being arranged angularly and the stave bent,
the ends of the stave will be cut narrower than its middle.
If staves are required to be cut for parallel barrels or casks, the before mentioned
sliding table is made flat instead or rounder.
Both sides of a stave or staves may be cut at the same time, or only one saw may
be used if required.
Instead of using saws the stave or staves may be cut by a knife or knives caused
to descend in a groove or grooves, on to the stave to be treated by a foot lever or
other suitable means. In a machine for this purpose for cutting staves suitable for
bulge barrels, the upper or cutting knife is slightly curved as seen in plan, as also
is the fixed knife, to suit the varying width of the stave at its ends and intermediate
parts of its length. Suitable brackets or a moving table are or is provided on which
the stave to be cut is placed, and which may be inclined to give the necessary bevel
to the edge of the stave. Stops or guards are arranged so as to enable various
*widths of staves to be cut as required, also to guide the stave under the knife that
both ends may be the same width.
If parallel staves are to be cut, the cutting and fixed knife or knives are made as
seen in plan straight, that is to say, flat on the face.
Tapered staves suitable for bulge barrels inay ho cut with a flat or straight knife
or knives for which purpose the table on which the stave to be treated is placed, is
rounded on the surface, to a contour corresponding to that of the interior of the
bulge barrel, one end of the stave being held down on the rounded table by a recess
or catch, the other by an eccentric or cam, or by a suitable cross bar with screwя,
eccentrics or other mechanical arrangements.
The table is placed-at-the-required angle to suit the bevel to be given to the
staves, and is also provided with stops, guides or gauges. One or more knives may
be used.
