Office of the Commissioners of Patents, with his Petition, on the
15th September 1875.-A communication from abroad by Louis
Florian Pile, of Fives, Lille, Department du Nord, in the Republic
of France.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THE
PREPARATION OF THE STAVES OF CASKS, TUBS, AND OTHER LIKE RECEPTACLES," a
communication to me from abroad by Louis Florian Pile, of Fives, Lille,
Department du Nord, in the Republic of France, to be as follows:
-
This Invention has for its object reducing the number of operations
required in the manufacture of the staves for casks, tubs, and the like;
and thus obtaining a more rapid and consequently less costly production,
and at the same time a more uniform result.

page_text: notch, that is to say, the groove for holding the end or bottom of the
cask or similar receptacle and the bevel, that is to say, to cut the stave
in the longitudinal direction. .
The machine is composed of two distinct parts, viz., a frame or bed
and a carrier sliding thereon. The frame or bed plate which may be of
_cast_iron_carries the mechanism of vertical tools, the function of which
to cut the stave in the direction of its length, that is to say,-to-form
be bevel. The upper carrier which slides upon the bed carries the
mechanism of horizontal tools whose function is to form the croze or
chimb notch; at the same time the staves are cut to the required length
by the same tools or by a saw placed behind the tools.
The carrier is caused to move upon the bed by means of a longitudinal
screw and a nut acting as a pinion, the motion being derived from the
driving shaft and transmitted by means of pullies and a bevel pinion to
the nut. A clutch or coupling is provided so as to enable the carrier to
be moved in either direction, that is to say, backwards or forwards, as.
required.
The stave to be operated upon is placed in a suitable gauge or
template fixed on the moveable carrier, and is held firmly in position by
means of a cast-iron head or block, which may be raised and lowered as
required by means of a screw and hand wheel; the stave thus passes
between the vertical knives or cutters, the inclination of which has been
previously adjusted in such a manner as to cut the edges of the staves
to the angle required so as to form a perfect joint when put together.
The carrier is provided with a cross pieco supported on four columns,
upon which the mechanism of the horizontal tools is fixed, the whole of
this mechanism is supported by a shaft mounted in bearings depending
from the cross piece, and can be caused to ascend or descend as required
-by-means_of_a_screw and suitable wheels; these tools may be moved
apart or brouglit-in-closer-proximity-as required according to-tho-length=
of-the stave, the spindles carrying the tools sliding in bearings, the
height of which may be adjusted by means of screws and slots. The
stave having been placed in the gauge or template the vertical tools
have a rotary motion imparted to them by means of pullies, and the
tools are caused to act upon the stave by means of wheels working
screws, which communicate the motion by means of moveable nuts in
the bearings before mentioned; the motion thus obtained is a circular

page_text: one, the axis of which corresponds with the centre line or axis of a
cask of which the stave being shaped in the machine may form part.
This machine which forms the bevel and the croze or chimb notch
simultaneously may likewise be arranged to perform these operations
soparately, the two series of mechanism being independent of each
other.
