Machine for Square Turning, to Turn such Articles as Staircase
Newils and Balusters, Table and Sofa Legs and the like, Square
Instead of Round.
JOHN C. V. STACEY, 70 Cherry Tree Road Sharrow Sheffield, Wood Turner &c.
I do hereby declare the nature of this invention to be as follows:-
This invention for square turning consists of a piece of ordinary round shafting
upon which is placed two large drums.
The features of novelty claimed in this invention are-First-The manner of
securing the various articles inside the circumference of drum, by a recessed flange,
and two small steel pins. Secondly-The manner in which these articles are firmly
attached to the above inside circumference, and recessed flange, by four loose Iron
sections of rings, fitting upon four Iron cramps which are raised or lowered (to suit
size of article to be turned) by four holt screws, placed between opening in each of
four arms radiating from central boss of Drum. Thirdly-A large wooden ring
attached to the inner circumference of metal drum by four screws, diminishing size
of drum, for fewer articles.
In letter D is shewn a perspective view of machine complete; fitted up with
articles to be turned.
It is intended to work this machine by steam or other motive power, by placing it
between the centres of an ordinary turning lathe or by fixing shafting in pedestal
bearings and driving with pulley and band.
No. 71. Round shafting.
No. 72. Key way throughout shafting.
No. 73. Key to secure the two drums (No. 74) in position on shafting, according to
length of articles to be turned.
No. 76. Four arms radiating from central boss to outer rim of drum No. 75.
One of the articles to be turned as No. 83 is passed between the radiating arms of
drun into the lower part of inside circumference of rim of drums. This first article is
firmly secured in position at right angles to ends of drum by a sharp steel pin,

page_text: which is attached to inner circumference of each drum; this also ensures that each
succeeding article shall be exacily parralel to first article so placed, and in a horizontal
position.
To secure these articles from moving endways, a raised flange as No. 79 A,
letter D is cast upon this inner circumference of drum.
When a portion of the articles are so placed in position, a section of Iron ring as
No. 82 is laid upon them.
In the open space in each radiating arm is placed a boli screw as No. 77-the
square head of which projects through the outer rim of drum as No. 78, to receive
spanner.
This bolt screw being used to raise or lower an Iron cramp, as No. 79.
By this cramp section of Iron ring mentioned above is firmly screwed down to back
of articles to be turned, securing them so that the machine may be turned round and
another portion of the articles placed as above. This is repeated with the four sections
of Iron rings & cramps in each drum, until the machine is filled.
To secure the bolt screws from turning when machine is in motion a small flat iron
plate as No. 80-is laid upon each radiating arm, a screw as No. 81-passes through
the centre of this plate, and screws upon and thus secures the bolt screw.
The machine is now in working order and one side of each article is turned to any
design. After which small flat Iron plate as No. 80-and cramps as No. 79-are
sufficiently loosened in succession, so as to allow each article to be so placed that
another of the faces may be turned as before. This is done, until each of the four
sides of article is turned to design:
A finished article is shewn at letter N.
Letter A. Elevation of side.
This Elevation shows No. 1-a length of shafting, with key way (No. 2) from end
to end, upon which is placed two drums (No. 3).
These drums may be fixed any distance apart according to length of articles (as

Instead of Round.
JOHN C. V. STACEY, 70 Cherry Tree Road Sharrow, Sheffield, General wood turner,
Carver &c. I 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 for square turning consists of a piece of ordinary round shafting
upon which is placed two large drums.
The features of novelty claimed in this invention are
Firstly The manner of securing the various articles inside the circumference of
drum by a recessed flange and two small steel pins.
Secondly The manner in which these articles are firmly attached to the above
inside circumference and recessed flange, by four loose iron sections of rings fitting
upon four iron cramps, which are raised or lowered (to suit size of article to be turned
by four bolt screws placed between opening in each of four arms, radiating from
central boss of drum.
And Thirdly A large wooden ring attached to the inner circumference of metal
drum, by four ordinary screws, diminishing the size of drum, so that a smaller quantity
of articles can be turned if required.
In letter D is shewn a perspective view of machine complete, fitted up with articles
to be turned.
.It is intended to work this machine by steam or other motive power, by placing it
between the centres of an ordinary turning lathe, or by fixing shafting in pedestal
bearings, and driving with pulley and band.
No. 71. Round Shafting. No. 72. Key way throughout shafting. No. 73. Key to
secure the two drums No. 74. in position on shafting according to length of articles to be
turned. No. 76. Four arms radiating from central boss to outer rim of drum No. 75.
One of the articles to be turned as No. 83 is passed between the radiating arms of
drum into the lower part of inside circumference of rim of drums.
This first article is firmly secured in position at right angles to ends of drums by a
sharp steel pin, which is attached to inner circumference of each drum. This also
ensures that each succeeding article shall be exactly parallel to first article so placed,
and in a horizontal position.
To secure these articles from moving endways a raised flange as No. 79 A letter D,
is cast upon this inner circumference of drum. When a portion of the articles are so
placed in position, a section of Iron ring, as No. 82 is laid upon them. In the open
space in each radiating arm is placed a bolt screw as No. 77. the square head of which
projects through the outer rim of drum; as No. 78, to receive spanner.
This bolt screw being used to raise or lower an Iron cramp, as No. 79. By this
cramp, section of Iron ring mentioned above is firmly screwed down to back of

page_text: articles to be turned; securing them so that the machine may be turned round, and
another portion of the articles placed as before. This is repeated with the four
sections of Iron rings and cramps in each drum until the machine is filled. To secure
the bolt screws from turning when machine is in motion, a small flat iron plate as
No. 80, is laid upon cach radiating arm. A screw as No. 81 passes through the
centre of this plate and screws upon, and thus secures, the bolt screw.
The machine is now in working order and one side of each article is turned to any
design. After which small flat iron plates as No. 80, and cramps as. No. 79 are
sufficiently loosened in succession so as to allow each article to be so placed, so
that anotlier of the faces may be turned as before. This is done until each of the
four sides of article is turned to design. A finished article is shewn at letter N.

end, upon which is placed two drums No. 3, these drums may be fixed any distance
apart according to length of articles, as No. 13, to be turned. The drums are secured
to shaft by key No. 15, and also by set screws through boss of drum, (see B. No. 18.)
Boss of drum is shewn at No. 3 A. No. shews section of radiating arms.
No. 5 shews section of rim of drum. No. 6 shews small steel pin screwed into the
inside of rim of drum, upon which is placed one of the articles to be turned, as
No. 18. And No. 13 passes inch under rims of drums, as shewn at No. 5. and is
secured endwise by a flange as shewn at B No. 20. and 20+.
No. 7 is a bolt screw, placed in the centre of radiating arm. The point of screw
works in countersunk hole (No. 14), on boss of drum (No. 3A.) and passes through
the cramp (No. 8) raised or lowered by said screw to suit thickness of article to be
turned (as No. 13.)
This cramp (No. 8) also fastens section of iron ring (No. 9) which firmly secures.
