Improvements in Carving Machines to Produce Carved Articles
Mechanically.
I LOUIS HYPOLITE AMETTE of 167 Pentonville Road in the County of
Middlesex, Saw Mill Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to improvements in carving machines to produce carved
articles mechanically.
To perform this I make the machine circular in shape, the action is vertical, but
I can if desired, make it either horizontal, longitudinal or transverse.
The machine to carve any number of articles at once, whether of the same pattern
or different.
It is composed of a fixed vertical spindle on a base, on this said spindle is another
hollow one, working on two hollowed washers, balls being placed round, thus making
a ball bearing which allows it to work very smoothly.
To the said spindle is fixed a piece holding a camn, thus giving the motion to all
the pieces to be carved.
I also have another moveable piece, which acts according to the cam used.
To the upper part of the said hollow spindle is fixed a large cone pulley which
gives the motion to the drills by any suitable means.
The drills used in this machine are held by a circular horizontal frame.
The drills are made of pieces of steel with saw teeth on one side and a cutting
edge on the other.
I can have round the machine a number of slides either single or double which act
mechanically by means of toothed pinions which allow the design to be varied on
each slide on which is performed the pointing process.
The pieces the machine is executing are suspended above the drills which gives a
superior cut, all the shavings and scrapings falling out, there being no fear of oil
spots. I can if desired have several metallic brushes, which allows the article being
carved to be finished in a superior way.
By means of the same mechanism, machines can be made to carve any number of
pieces according to the size and build of the said machine.

Improvements in Carving Machines to Produce Carved Articles
Mechanically.
I, LOUIS HYPOLITE AMETTE of 167 Pentonville Road, in the County of
Middlesex, Saw Mill Engineer 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:-
To perform this, I make the machine circular in shape; the action is vertical,

page_text: but I can, if desired, make it either horizontal, longitudinal, or transverse. The
machine to carve any number of articles at once, whether of the same pattern or
different.
It is composed of a fixed vertical spindle on a base. On this said spindle is another
hollow one, working on two hollowed washers, balls being placed around, thus making
a ball-bearing which allows it to work very smoothly.
To the said spindle is fixed a piece holding a cam, thus giving the motion to all
the pieces to be carved. I also have another moveable piece which acts according
to the cam used.
To the upper part of the said hollow spindle is fixed a large cone pulley which
gives the motion to the drills by any suitable means.
The drills used in this machine are held by a circular horizontal frame.
The drills are made of pieces of steel with saw teeth on one side, and a cutting
edge on the other.
I can have round the machine a number of slides, which act mechanically by means
of toothed pinions, which allow the design to be varied on each slide on which is
performed the pointing process. The pieces the machine is executing are suspended
above the drills which gives a superior cut, all the shavings and scrapings falling out
there being no fear of oil spots.
I can, if desired, have several metallic brushes, which allows the article being
carved to be finished in a superior way.
In order that my said invention' may be more readily understood and carried
into effect I will now proceed to describe the same with reference to the accompanying
drawings.
Sheet 1, Fig. 1 elevation of circular frame.
Sheet 2 Fig. 2. details of balancing board and slide rests.
Sheet 3 Fig. 3, plan of circular frame.
Sheet 4. Fig. 4 shows working of the drills or cutting tools, Fig. 5 is an enlarged
view of toothed wheel and ratchet, showing the action of working the traveller on
the slide rest.
The machine can produce a number of carved articles according to the number
of drills fitted thereto, and various patterns may be produced according to the
number of slide rests placed round the machine, each slide rest may have a distinct
pattern.
On Sheet 1 the base A has a screw and spindle B. to B. which varies the height
of the whole circular frame C. C, that carries the several moveable drills D. In
the bearing pivot E I place balls round, thus making an ordinary ball bearing, by
which means I obtain a movement of great smoothness. When the machine is at
work and the circular frame C. C. is revolving the cam F. then imparts the vertical
motion to the connecting rods P. and P' operating the catch or leaver Q. on the
toothed wheel R. By the above mentioned action the lifting spring I vertically
operates the balancing board H, thus taking the dead weight off or clearing the
drills D. At one end of the said balancing board is fixed the pattern to be copied
and at the other end underneath is placed the wood to be carved, this end always
being heavier than the other thus keeping the pattern pressed against the guide or
pointer U, which is held in position by the arm S.
The spindle J is hollow and supports and actuates the driving wheel K. by means
of the band V from the engin.
The power now being transmitted from the driving wheel K to the cone or
friction pinions M, shown on Sheet 1 and 4 thus communicating a rotary motion to
the drills D which are placed upon the circular frame C C. by the clamps O, the
said drills can be regulated at different intervals or spaces agreeably to the variations
in the pattern which is desired to work or operate with.
The drills D are of steel having a spindle L L. and with saw teeth on one
side and a cutting edge on the other, which is different to the drills in use at the
present time, but I do not confine myself to this description of tool alone the drills
are assisted in their rotary motion by the fly wheels N.

page_text: The before mentioned balancing board H is attached to the traveller G. at the
bearing G working on the slide rest X by means of the screw W.
When the traveller G has performed its work in one direction, its action is
reversed by the spring being pressed on the other catch or leaver Q', Fig. 2.
Sheet 2 or as shown by pawl or ratchet operated by a spring Fig. 5. Sheet 4, when
the reverse action is required this spring is turned round by hand or by a stop
placed on the slide connected thereto and presses against the other or lower pawl
or ratchet arrangement at Q' Fig. 5 thus reversing the action of the wheel R,
the first or upper pawl being thrown out of gear; or one pawl may be used by
working on a socket Q2; at the same time that the screw W is reversed the
wheel G'is opperated by hand or by suitable mechanism to feed the transverse slide
one step.
My invention provides for and permits of carvings being executed in marbel,
stone, and the harder substances.
The drills can if desired be exchanged for metallic brushes, with which latter to
finish and polish the carved article in a superior manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed; I declare that what I
claim is :-
:―
1. The combination of the movements, giving with very little motive power
effective action to a number of drills or tools.
2. The weight of the mechanism or whole combination resting upon a pivot at
the base.
3. The use of a cone fly wheel which imparts motion to the drills or tools, obviating
the use of all belting and gut bands.
4. A balancing board which facilitates the production of a fac-simile of a pattern
or model operated from either the right or the left, or underneath.
5. The slide rests acting by mechanical motion and allowing many articles to be.
carved at one time.
6. The balancing board being actuated mechanically thus dispensing with hand
work as at present needed.
7. The machine to be driven by any suitable and usual motive power, and the
whole combination as hereinbefore described.
