Barrel Finishing Machine.
I PETER JENSEN of 77 Chancery Lane, in the County of Middlesex, Chartered
Patent Agent, do hereby declare the nature of this invention a communication
to me from abroad by Nils Peter Hervig of Fredrikstad, Norway, Mechanician.
This invention consists in a machine for finishing or tooling the outer surface of
a barrel after the staves have been assembled. Such finishing has heretofore
been made only by hand or by primitive mechanical means.
The machine is constructed so, that when the barrel part fixed between end discs
slowly rotates, its outer face is finished by knives or planing irons preferably
curved, fastened on a rotating disc or wheel which may be plane or concave. The
shaft of this disc is in one way or other mounted so, that it may be moved up
against or away from the barrel and also in a tangential or lateral direction by
manipulating a handle. In this manner the finishing of a barrel can easily be
performed in a very short time.
A suitable construction of machine is shown in the drawings.
Figure 1 is a front elevation of this machine.
Figure 2 a side elevation and
Figure 3 a plan view partly in section.
The shaft B' of one of the discs B is by the tooth wheels E' and E geared with
the shaft D' of the pulley D by means of which latter the barrel is set in rotation
while the shaft C¹ of the other disc C is by a link F' connected with a lever F
serving to move this disc C in the axial direction, whereby the barrel may be held
between the discs or disengaged.
The tool or cutter G is mounted on a shaft G¹ rotated by a pulley H. This
shaft may be moved longitudinally in its bearings by an arm N the forked end of
which in a well known manner takes hold of the shaft and is connected with a
counterbalanced lever S with handle P, by means of which the shaft G¹ with the
disc G may be moved up against or away from the barrel. The bearings I and J
for the shaft G' are mounted on a bed plate L which can be swung horizontally
about a spindle K journalled in a supporting frame M, which is adjustable according
to the size of barrel; and from the bearing J an upright R reaches up past the
lever S and forms a guide for it during its up and down movement thus it is
possible to swing round the spindle K by the handle P and thereby cause the
disc G to swing out to the sides.
While the machine is working, the operator holds the handle P and moves the
same up and down, and to both sides, so that the whole face of the barrel is
touched and planed by the knives.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim
as the invention communicated to me is.-
1. In a barrel finishing machine a shaft for holding the barrel and keeping it in
constant rotation in combination with a rotatory cutter disc, the shaft of which is
movable in a longitudinal direction, and the bearings of which are mounted in such
a manner, that the cutter disc may be given a tangential or similar movement
relative to the surface of the barrel, while both the barrel and the cutter disc are
in rotation.
2. In a barrel finishing machine the combination of the shaft G' for the cutter
disc with bearings mounted on a plate pivotted to an axle K, at right angles

page_text: to the shaft of the cutter disc, so that a handle P by which this shaft can be
longitudinally moved, also may serve to swing the cutter disc around the axle K.
3. A barrel finishing machine substantially as described with reference to the
drawings.
