Fig. o snows a guide chuck and
Figs. 6 and 7 are a vertical section and plan respectively of the shaping tem-
plate and rod or stick holder. For the sake of clearness the guide chuck and
cutter are omitted in Figs. 3 and 4.
The machine consists of a knife head b rotating in a seating a made in two
or several parts, and on one side of the head 6 is cast a belt pulley c, whilst
the other side is provided with a ring shaped recess in which engages the con-
centric ring e which at its outer edge surrounds the sliding ring 9. The ring 9.
is prevented from falling out by the nut f and by means of the ribs h and screws i
is connected to a fork k. This fork is attached to the upper end of a bolt Z rotat-
able in a vertical seat m attached to the side of the seat a and carrying at its
lower end one arm n of a bell crank lever, the other arm o of which extends
into a recess 7 made in the lower part of the seat a through which latter the
shaping iron template 9 is carried.
The template (Figs. 6, 7) has a groover corresponding to the profile to be
given to the rod or stick and engaging in the groover is a round or oval shaped
studs fixed to the bottom side of the lever arm o and which by drawing along
the template q is forced to the left or right according to the shape of the groove.
This movement is so transmitted by the bell crank lever n o, bolt I, fork k and
sliding ring g to the ringe that the latter is forced out or in the circular groove d.
Adjustably arranged radially in the cutter head and passing through the
ringe are two or more guide chucks t and also one or more knife holders u.
The guide chucks are hollow bodies (Fig. 5) which by means of springs "
within them and screws 1, the heads of which bear against a plate r fixed in

page_text: the knife head, are forced towards the centre, in order to prevent the guide chucks
flying outwards on the rotation of the knife head.
The knife holder u is also a hollow body in which the turning or polishing
knife y is fixed in the usual manner and is also partially formed like a guide
chuck as shown by Fig. 2.
In both sides of the guide chucks and also of the knife holder u are arranged
inclined slots (Fig. 1) in which slide projections fixed to the ring. If the
ringe is moved in a horizontal direction by means of the before mentioned lever
action, the guide chucks and the knife holder are forced towards or away
from the centre by means of the projections accordingly as the ring is forced
inwards or outwards, which as before mentioned is dependent upon the groove r.
Consequently the shape determined by the template is imparted by this process
to the rods or sticks being operated upon.
The rod or stick inserted between the guide chucks and cutter y to be worked,
is suitably connected with the template, for example by clipping between two
horns 4, 5, (Figs. 6, 7) fastened on the template q in order that it may receive
the same movement as the template.
The guides which are used for the polishing of curved rods or sticks are step
shaped on their polishing surface Fig. 1 in order to give a guide to the worked
and also the raw surface of the article operated on.
The thickness of the shaving removed in the smoothing can be regulated by
the adjustment of the cutter. Both the guide chucks and knife holder can be
fitted with file attachments as may be desired.
For the purpose of polishing, the guide chucks are fitted with polishing pads
but the pads can, for working straight sticks, be fitted against, that is behind the
usual guide chucks.
The difference between the largest and smallest diameter to be worked with
the guide chucks and knife holder of a certain diameter depends upon the length
of the slot and extent of the movement of the ring e and consequently this
machine can be made as large as desired.
The above described construction of guide chucks and knife holder permits of
the working and polishing of curved circular rods or sticks by machinery, they
hitherto having to be done by hand.
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:-
1. Machine for turning and polishing curved and straight circular shaped rods
or sticks, characterised by a knife head b, rotating in a seating made in two or
more parts, provided on one side with a belt pulleye and on the other side with
a ring shaped recess d into which slides horizontally a concentric ring the outer
edge of which encircles a sliding ring g held therein by means of a nut f, the
ring g being connected to a tork k the bolt of which is actuated by means of
a.bell crank lever n fixed to its lower end, one arm o of which projects into an
opening made in the seating a and carries underneath it a projections which
engages in the groove r, corresponding to the shape to be given to the article
worked on of a template y passing through the opening and connected in any
suitable manner with the article worked, so that on the sliding through of the
template the ring is so acted upon that it is forred in or out of the recess in
the knife head according to the shape of the groove in the template.
2. With the machine described under 1 the arrangement of guide cheeks and
also knife holders consisting of hollow bodies adjustable radially in the
knife head band passing through the concentric ring e, which hollow bodies
by means of springs fixed therein in any usual manner are pressed against
the work, and which are provided on their sides with inclined slots in which
slide projections fixed to the concentric ring, whereby on moving the concentric
ring the guide and knife cheeks are forced inwards or extended outwards,

page_text: and which guide cheeks for the purpose of polishing are provided with polish-
ing pads on their contact surfaces, such surfaces being if desired made step
shaped in order to be in contact with the finished and raw part of the article
worked.
3. As a new product of industry curved rods or sticks which are smoothed and
polished by the machine claimed under Claims 1 and 2.
