PROVISIONAL SPECIFICATION.
Improved Appliances for use in Turning Cylindrical Staves and
the like.
We CARL WERNER and ROBERT PÖTZSCH both of Meerane in the Kingdom of
Saxony Empire of Germany, Manufacturers do hereby declare the nature of this
invention to be as follows:-
This invention consists in certain improved appliances forming a machine for
turning cylindrical staves and the like of indefinite length as hereinafter described.
The improved appliances comprise a rotary block for holding or supporting the
adjustable cutters and an adjustable holder or head stock for guiding the stave, in
conjunction with the head stock supporting the hollow mandril to which the cutter
block is attached.
The cutter block is formed of a cone, having on its outer surface raised bars
lying from the base to the summit, having on one face shears by which the movable
bars to which the cutters are fixed are guided so as to be movable along the cone.
The said movable bars are adjusted by screw threaded spindles, revolving in lugs
on the raised bars, and engaging in female threaded nuts, fixed to the movable
bars; each spindle is provided with a bevelled spur wheel and all the bevelled spur
wheels, engage in a bevelled toothed annulus surrounding the cone and revolvable
thereon so that by revolving the said annulus or one of the said spindles, all the
spindles are equally and simultaneously revolved and the cutters moved along the
cone and consequently approached or receded from each other. The improved head
stock comprises two V shaped bodies, vertically guided so as to enclose a more or less
rectangular space between them, the same being made greater or less by simultaneous
movement of said bodies from or towards each other by means of a spindle with
contrary screw thread.
The said cutter block or head stock may be fitted on any suitable lathe. In the
improved machine comprising them the said head stock may support the implaned
stave, the latter passing through the cutter block and through the hollow mandril to
which the block is attached and be supported by springs attached to the headstock of
the mandril.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The cutter block consisting of a hollow truncated cone and knives adapted to be
simultaneously adjusted, each in a plane parallel to a plane in which the axis of the
cone lies.
2. The cutter block consisting of a hollow truncated cone with bars g carrying
knives and adapted to be guided on the cone substantially as set forth, screw
spindles d, toothed wheels and toothed annulus 6 for simultaneous adjustment of
said bars g and knives.
3. The combination of a hollow truncated conical support, having shear plates c
thereon, bars adapted to be adjusted in said plates e projecting fingers n on said
bars, and knives fon said bars adjustable thereon athwart the line of adjustment of
the bars for the purpose set forth.
4. A head stock comprising the two V shaped bodies or frames o. o¹ adapted to be
simultaneously adjusted so that the centre of the adjustable space enclosed by them
remains stationary for the purpose set forth.
5. The combination of the hollow mandril z with springs PP.
the cutter block a
constructed substantially as described and attached to said mandril and the headstock
or guide having the plates o o' adapted to cooperate substantially as and for the
purpose set forth.
