PROVISIONAL SPECIFICATION.
Wood Forming or Turning Machine for Cornice or Curtain Pole
Rings or other Rings.
I, WILLIAM SAMUEL BEMI of 31 & 32 Nelson Street Peter Street Hackney
Road, London E. in the County of Middlesex, Wood Turning and Moulding
Manufacturer do hereby declare the nature of this invention to be as follows :—
A wood turning or forming machine for producing cornice or curtain pole rings
or other rings.
I propose using two cutter heads with spindles revolving in gun metal bearings
with cutter block fixed on end of spindle on which the cutters to form the rings are
fixed. The cutters are made the convex shape of half of ring to be formed, and
the cutters are so made and adjusted on the cutter blocks to present a cutting edge
to wood same as performed or presented by the cut of ordinary hand turning tools.
Each side of ring is formed by several cutters, but all cutting in the same
revolution of spindle.
The wood to be formed into rings is clamped in a vertical frame with set screws,
it is then worked horizontally by means of slide attachment worked by screw
beneath slide with spur gearing and crown wheel and handwheel in front of bed (or
may be worked by hand with lever arrangement). The wood is then brought
against the revolving cutters alternately to form each side of ring, by this
operation the inside of ring is finished.
To finish the outside or outer edge of ring the partly finished ring is then worked
forward by means of slide attachment or by lever arrangement (or by hand without
Ecrew attachment) to get ring into position in front of the third cutter head-which
head has revolving cutting off tools, which are set to clear off outer edge of ring
and cut ring away from the waste wood, this last operation finishes ring.
A pin is fixed on under side of slide which works in a slot in bed of machine to
prevent ring being placed into wrong position in moving forward to cutter or
reverse or horizontal movements.
To prevent the ring being broken by the cutters after forming same I purpose
fixing inside the third cutter bead block a forcing plate with spiral (or direct)
springs at back of plate, the plate by means of the springs is pressed against the
ring untill it is cleared by the cutters from the wood and then forced forward away
from the cutters avoiding breakage of ring-1 may use other springs in place of
spiral, or india rubber pad or plates for forcing ring from cutters.

Wood Forming or Turning Machine for Cornice or Curtain Pole
Rings or other Rings.
I WILLIAM SAMuel Bemi of 31-32 Nelson Street, Peter Street, Hackney
Road, London E. in the County of Middlesex, Wood Turning and Moulding
Manufacturer, 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 a wood forming or turning machine for producing
cornice pole-or-curtain-rings or other rings in wood or other material.
Fig. 1 represents a general view of the machine. H are the cutter heads with
spindles S revolving in bearings B. Care cutter blocks made to revolve on end
of spindles S-the cutter blocks C are fitted with cutters or turning tools T the
shape of each being made the convex shape or part of the shape of ring R to be
formed, the cutters or turning tools T are fixed as near as possible on an angle, the
same as presented by the cutting edge of an ordinary hand wood turning tool.
Fig. 2. shows front view of the cutter blocks C with cutting tools Teach the
reverse part of the shape of ring R to be produced, but I may use more cutters or
tools T than are shown in Fig. 2. thereby producing cleaner work.
Each side of the ring R, is formed by separate sets of cutters C, T, Fig. 2—but
all revolving at the same time.
The wood R to be formed into a ring is fixed in a vertical holder or frame D.
and kept in possition by means of set screw K and plate under set screw R 2.
After the wood is fixed in the holder D it is then worked horizontally by means
of slide attachment V worked by screw N beneath slide V with spur gearing and
crown wheel and hand wheel W, W, at end of machine, (or may be worked by
lever arrangement). The wood R is then brought against the revolving cutters
alternately to form each side of the ring R.
To finish the outer edge of ring or cut ring R off from the waste wood, the
partly finished ring R still remaining fixed in holder D, is worked backward in
slide M. by means of handle L to get partly finished ring R. into possition to be
finished or cut off by tools P-the cutters P are revolving as other cutters-the
wood R is brought against cutters P horizontally by means of screw N, and
wheels W. W.
To prevent the ring R. being broken after being formed by the cutters P, I use
forcing plates or buffers F with springs F. T. Fig. 3. The buffer is held in
possition by pins or rods O, these forcing plates F by means of the springs F T
are pressed against the face of the ring R and directly the ring R is cleared from
the wood the springs F. T. force the ring R forward from the cutters, thereby
avoiding breakage of rings by the cutters.
I may use direct springs in place of spiral springs or india rubber at back of
plates for buffers F or forcing plates.
I may also use these forcing plates or buffers F. O. O. on the cutter blocks C
Fig. 2 and dispence with back cutter block C. C.
Plate 2 shows full size drawing of the cutters T 1. T 2. Fig. 5 has a point for
clearance which Fig. 4 has not, the inside of these cutters are the exact reverse
shape of the ring R.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, I declare that what I
claim is-
1st. The combination of two or three cutter heads H. and blocks C. with

described and shown for the purpose specified.
2nd. The combination of revolving turning tools as cutters T. T 1-T 2—on
cutter blocks Figs. 2-3-4-5 and before described for the purpose specified.

buffers F-F. T. worked by springs or india rubber (Fig. 3) for clearing rings from.
cutters T. P as shown and before described for the purpose specified.
4th. In the holding of the material to be formed into rings, in a vertical frame-
or holder D with a backward and forward movement and horizontal movement as
shown Fig. 1 and before described for the purpose specified..
5th. The general combination and arrangement of the parts constituting this my
machine for the purpose specified and substantially as described and illustrated in
Plates 1 and 2.
