I WILLIAM SAMUEL BEMI of Phoenix Saw Mills, Mansford Street Hackney
Road London E in the County of Middlesex do hereby declare the nature of
my invention for IMPROVEMENTS IN APPARATUS EMPLOYED FOR TURNING FOUR
OR MANY SIDED OBJECTS IN WOOD OR ANY, SUITABLE 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
Figur 2 is a longitudinal section, Figure 6 is an end view.
Figures 4. 5. 7. 8 show details.
Like letters indicate the same parts throughout the Drawings.
This machine is similar in some parts to my Invention 3072. A.D 1884.
A spindle C is placed in two brass bearings or fixed between ordinary.lathe
heads, on this spindle C³ at each end is fixed an iron hoop or rings C, C₁ C on the
outer surface of these rings C is fixed a wooden drum W by means of bolts L, the
circuniferance 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 C by means of bolts L, the surface of the drum is level with
rings C thereby fixing flats (Fig 5) on ring C parallel with flats on drum W.
The ends or edges of rings are provided with a flange F' 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," In place of struts R. I can use a over-
hanging flange F¹ figure 8 with set screws on top E.
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 pieces of wood to be turned are placed around the drum W on the flats in a
horizontal plane between the pins P and struts R. on flange F' and set screws T and
pins P on flange F'.
.
After the pieces of wood are placed around the whole circumferance of the
drum W. I employ the following method of securely fastening and holding them.
I use a pair of clipps A Figure 6 (made of steel or any suitable material) at each
end of the drum, these clipps A are made in semecircles or as many sections of a
ring as I may deem expedient, these have projecting ends or luggs M to each,
a bolt S passes through each end and a nut and bolt N tightens the pair firmly

these bands A moving out of place and better adjusting them a rest or arm B
Figure 4 is fixed to the drum C by means of bolt D. the band A passes through
these arms B thereby keeping them in their place. 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 bands A are
loosed, the peices of wood are replaced on their reverse side and the surface turned
in a simelar manner, then the third and fourth side.
This machine can be used for turning as inany 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 iron, or
any suitable material prefered.
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 C
thereby making a solid drum substantialy as above set forth.
Second. The fixing of wood around the under circumferance of iron hoops or
ring C, thereby making flats on drum W. parallel with flats on rings Figure 5 or 7.
Third. In a wood turning machine the method of fixing each peice of wood to be
turned between a strut and piu at one end (or set screw on flange figure 8) 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 pair of clipps A and fastened by luggs M and bolts S and N, or other suitable
mechanism to fasten these clipps.
