WILLIAM SAMUEL BEM, of Phoenix Mills, Mansford Street, Hackney Road
London E. in the County of Middlesex, Wood Turner, do hereby declare the nature
of my Invention for IMPROVEMENTS IN APPARATUS FOR TURNING FOUR OR MORE
SIDED OBJECTS IN WOOD OR ANY SUITABLE MATÉRIAL to be as follows:-
I employ the following mode of carrying this Invention into effect. A Spindle
is placed in two Brass Bearings, or fixed between ordinary Lathe Heads or Centres,
on this Spindle is fixed a Wooden Drum, at each end of the Drum is fixed an Iron
Hoop or Ring, the circumferance of the Drum and Rings are not quite circular but
made with flat surfaces of Polygonal form in a Horizontal Plane. The ends or
edges of the Rings are provided with a Flange, on one of these Flanges at proper
distances is fixed small Struts or Pins in a Line with the Flats on the Drum
and Rings. The Flange at the other end is provided with small Set Screws in line
with the Pins or Struts. The Pieces of Wood to be Turned are placed around the
Drum on the Flats in a Horizontal Plane between the Pins or Struts on one Flange
and the Set Screws on the other. After the pieces of Wood are thus placed in
position around the whole circumferance of the Drum, I employ the following
method of securely fastening and holding them. I purpose using a Ring or Holder
at each end of the Drum, this Ring or Holder is made in two or three separate
parts, or as many Sections of a Ring as I may deem expedient, each Section or
Holder is attached to the outer end of the Drum, and allowed to work in Slots
or Slides or Gearing, a Screw and Nut working in a Collar or Bearing suitably
fixed is provided to enable the Holders to be adjusted and fixed, the Holders on
the outer or Top Edge are made with a Flange projecting over the Drum sufficient
to catch or hold the Ends of the Pieces of Wood which have been placed around
the Drum for Turning, by using the Screws and Nuts the Holders are brought
firmly down on the Wood, and thus securely fastened. These Holders are used for
the whole circumferance of the Drum and at each end. After the Wood has been
thus fixed over the entire circumferance of the Drum, the Drum is made to revolve
and the whole surface is Turned, after the first side has been finished, the Holders
are loosed by means of the Screws and Nuts then the Pieces of Wood are reversed
and replaced in position and the surface Turned in a similar manner, then the
third and fourth side. This Machine can be used for Turning as many sided
objects as desired, the Wood being first Cut or Planed to any Polygonal form, then
placed around the Drum, the Flat surfaces being presented for Turning and
replaced in succession till the whole number of sides have been Turned. This
machine can be made out of Wood or Iron or any suitable material preferred.

the nature of my invention for IMPROVEMENTS IN APPARATUS EMPLOYED FOR
TURNING FOUR OR MANY SIDED OBJECTS IN WOOD OR ANY MATERIAL and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement: —
I employ the following mode of carrying this Invention into effect in which—
Figure 2 is a longitudinal Section.
Figure 6 is an End view.
Figure's 4, 5, 7, 8, and 10 show details.
Like letters indicate the same details throughout the Drawings.
A Spindle C, is placed in two brass bearings or fixed between ordinary Lathe
Heads, on this Spindle C at each end is fixed an Iron Hoop or Ring C. C, C4, on
the outer surface of these Rings C, is fixed a Wooden Drum W by means of
bolts L, the circumferance of the Drum W is not quite circular but made with
Flat surfaces of Polygonal form, in a Horizontal Plane W, Figure 5 is a section of
front view, showing the Wooden Drum W fixed to the under surface of Rings O
by means of bolts L, the surface of the Drum is level with the Rings C, thereby.
fixing Flats (Figure 7) on Rings parallel with flats on Drum W.
The ends or edges of Rings are provided with a Flange F¹ attached to C¹ by
means of arm H, on one of these flanges F' at proper distances is fixed small
Struts R and Pins P, in a line with the Flats on the Drum W.
The Flange F at the other end is provided with small Set Screws T, and Pins P,
in a line with the Struts R.
The peices of Wood K, to be turned are placed around the Drum W, on the
Flats in a Horizontal plane between the Pins P and Struts R, on one Flange F',
and the Set Screw T and Pins P on Flange Fª.
After the peices of Wood K to be turned are placed around the whole circum-
ferance of the Drum W, I employ the following method of securely fastening and
holding them.
I purpose using a Ring or Holders A. A³ (Figure 6) at each end of the Drum W,
these Rings or Holders A are made in two or three parts or as many Sections of
a Ring as I may deem expedient, each Section or Holder A is attached to the
outer end of Drum W, and Ring C₁ and allowed to work in Slots or Slides B.
E, E³, (Figure 8) the Pin E working in Slide E is fixed to O' by means of an
Arm and Screws E³.
B. are plates to form Top of Slide. In place of slides I may use Slots or
Gearing or other suitable mechanism to work the Holders.
A Screw S, and Nut N, (kept in place by plate D) working in a collar or
Bearings, M is connected and suitably fixed to Holders A, this Screw S is fixed to
a Boss S³ by means of S³, the Nut N working in Bearings M.
The outer or Top edge of Holders A are made with a Flange A projecting over
the Drum W sufficient to catch and hold the peices of Wood K which have been
placed around the Drum W for turning.
These Flanges A³ are fixed to Holders by means of Arms V, (Figure 6) they are
thus arranged as to enable me to use Flanges of larger or smaller Diameters.
By using the Nut N the Screw S draws the Holder A* closer to the Drum W,
.thereby bringing the Holders A* firmly down on the wood K, and thus securely
fixing them for Turning.

page_text: These Holders are used for the whole Circumferance of the Drum and at
each end.
After the Wood has been thus fixed over the entire circumferance of the Drum,
the Drum is made to revolve and the whole surface is turned, after the first side
has been finished the Holders A are loosed by means of Nut N and Screw S, then
the peices of Wood K are replaced on their reverse side in a similar manner,
then the third, and fourth sides.
I can use this Machine for Turning as many sided objects as desired, the Wood
being first cut or planed to any desired Polygonal form. Then placed around the
Drum, the flat surfaces being presented for turning, and replaced in succession till
the whole number of Sides have been turned.
This Machine can be made of Wood or entirely of Iron, or any suitable
material.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is;-
First. The fixing of Wood around the. circumferance of Iron Hoops or Rings,
thereby making a solid Drum, Substantialy as above set forth.
Second. The fixing of Wood around the under circumferance of Iron Hoops or
Rings C, thereby, making the Flats on Drum W, parallel with Flats on Rings
(Figure 7) Substantialy as above set forth.
Third. In a Wood Turning Machine the method of fixing each peice of Wood to
be turned between a Strut and Pin at one end and a Set Screw and Pin at the
other end, on the outer circumferance of a Drum and Ring, Substantialy as above
set forth.
Fourth. In a Wood Turning Machine securing the Wood to be turned by means
of a movable Holder A, worked by means of a Screw S, and working in Slides E
or other suitable mechanism to work these Holders, Substantialy as described and
set forth.
