page_text: I, DÉSIRÉ DELBEY, of 58, Rue de la Roquette, Paris, France, Statuary, do
hereby declare the nature of this invention to be as follows:-
The present invention concerns a machine for rough cutting sculpture in wood,
marble, ivory and the like, according to model, also for executing the enlargement
reduction and counter-part of this model.
The machine is composed of a lower part or fixed frame and of an upper movable
part. The frame supports a small puppet bearing the tool which turns by
means of straps and pulleys actuated by a pedal; the frame, moreover, supports
a pivot bearing a cross-beam which swings on this pivot to give a circular and
vertical movement to the upper part of the machine which is fixed on this cross-
beam; this movable part of the machine can slide to the right and left, by means
of an endless screw fitted in the above-mentioned cross-beam and a grooved plate
upon which two lengthening pieces are fixed by means of pivots, this allowing
them to slant to the right and left to constitute the horizontal movement; these
two lengthening pieces are connected by small cross-bars which render their
movements conjointly liable; on one of them the model is placed and on the other
the matter to be sculptured, in proximity to the tool. Bolts forming pivots pass
through joints adapted to the lengthenings and allow the lower parts of these
said lengthenings to slant to the right and left.
A guide, displacing according to the pivot which bears the movable part of the
machine for the enlargements, reductions and counterparts and fitting into its
slide by a bolt, serves to follow the sinuosities of the models which is brought
with the hand into contact with the guide, these movements being repeated from
point to point by the lengthening piece which bears the matter to be sculptured
so, that the tool executes on the matter to be sculptured, all the sinuosities
followed by the guide on the model.

The subject of the present invention is an apparatus intended for the repro-
duction of given models of sculptures in marble, wood, ivory, etc.
The annexed drawing which is given by way of example, illustrates one method
of carrying the invention into practice.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a view of the apparatus in side elevation.
Fig. 2, is a view of the rear face.
Fig. 3, is a view in plan, of the rocking part of the apparatus and serving as
support for the model and for the block which it is desired to sculpture.
Fig. 4, is a view of showing a detail of construction.
The apparatus consists of a frame A supporting an ordinary puppet head of a
drilling counter sinking or recessing machine B, which puppet head carries the
tool B; the frame likewise supports through the medium of two plummer blocks
and gudgeons E capable of rotating in the said plummer blocks, a frame C com-
posed of two longitudinal pieces and of two transverse or cross pieces fixed at the
extremities of these latter. In this frame is mounted a screw having a square
thread which can be rotated by means of a crank-handle a Upon this screw is
threaded an eye bolt 9 which is capable of sliding between the longitudinal side
pieces of the frame towards the front or rear, in accordance with the direction
of rotation imparted to the screw spindle F as is indicated by the arrows m and m¹
(Fig. 3).
Beneath the frame is fixed, by means of a lug provided at its extremity; a stem
or rod X parallel to the frame and carrying a counterweight 1), which latter can
be displaced lengthwise upon the said stem or rod X and secured at any desired
point by means of a clamping screw.
Upon the frame C rests a plate G in which is cut a groove or slot wherein works
a projecting portion of the eyebolt of the frame, and which admits of displacing,
as indicated by the arrows n and n¹ (Fig. 3), the plate in a transverse direction
with respect to the latter, a clamping screw f fixing the said plate in the required
position.
Towards each of the extremities of the plate G is provided an arm H mounted
upon a pivot b, and free to oscillate round the said pivot. To each of these arms
is connected by means of a gudgeon forged in one piece with H, a lengthening
piece I or I¹ having a longitudinal groove or slot k. The two lengthening
pieces I and I¹ are connected together by three transverse or cross pieces J, K, L,
in the following manner: at its front end each of the lengthening pieces possesses
a sleeve m" through which passes the gudgeon (Fig's. I, and 3), and cast in one
piece with which is a square piece o the upper portion of which is provided with
a hole in which engages a cylindrical tenon y which forms the lower part of an
upright having two branches between which is articulated upon a pin o one of
the extremities of the transverse piece J. A small pin w prevents the tenon from
leaving its hole whilst admitting of its rotating freely therein.
At the rear extremity of each of the lengthening pieces is fixed a sleeve mill,
similar to the sleeve m", carrying an upright q corresponding to j, to which
upright is articulated or jointed one of the extremities of the transverse or cross
piece K, by means of the pin o¹, this upright is also connected to the square
piece o of the sleeve m¹, by means of the pin or bolt y'.
Lastly in the sleeve mi is capable of turning freely a gudgeon ", kept in
place by a pin 20¹, fixed to a stirrup L¹ between the forks or branches of which
is articulated by means of a pin one of the ends of the transverse or cross
piece L'.
The transverse or cross pieces J, K, and L, by coupling together in the manner

page_text: herein above described the two lengthening pieces I and I¹, ensure the similtude
and the parallelism of their movements.
Upon the two lengthening pieces I, I', are mounted uprights M which can be
displaced, by means of the grooves or slots in these lengthening pieces, along
these latter, clamping screws d¹, d, being provided for fixing these uprights
at the required points, and the said uprights themselves carrying clamping
screws d, d. Upon the side of the frame opposite to that carrying the head B is
fixed a centre or guide point or piece N, by means of a clamping screw.
At the lower part of the framing is mounted a grooved wheel or pulley P free
to rotate upon a pin fixed to the said framing, and receiving through a pedal Q
the motion which it transmits by means of a cord or belt to the tool.
The arrangement of the part of the apparatus carried by the frame C upon the
pins E admits of the rotation of that part in a vertical longitudinal plane follow-
ing the direction of the arrows p, 2 (Fig. 1.); the rotation, of the arms H upon
the pivots b and consequently of that of the lengthening pieces I, I, which are
connected to them admits of the displacement as indicated by the arrows 4, q',
(Fig. 3), following a plane horizontal or inclined and perpendicular to the pre-
ceding lastly the rotation of the the front ends of the lengthening pieces I, I,
upon the pins belonging to the arms H admits of the uprights M, M, being
inclined as indicated by the arrows r and r¹ (Fig. 2).
In short the arrangement of the transverse or cross pieces J, K, L, upon their
pivoting supports, ensures the constant parallesim of the lengthening pieces I, I',
and of the uprights M, M, which they carry. The operation of the apparatus is
as follows:
The centre or guide point or piece N, is placed in the prolongation of the
tool B¹; the model to be reproduced is fixed upon the lengthening piece I corres-
ponding to the guide N, by means of the uprights M and of the clamping
Screws , d; the material to be sculptured is then fixed in the same manner upon
the second lengthening piece I, corresponding with the tool B
The centre or guide piece or point N is next adjusted upon the most projecting
point as also with the approximate centre of the model, whilst the tool B' is
regulated or adjusted relatively to the approximate centre of the material to be
worked; the model is then moved by hand against the fixed guide, all the
sinuosities presented by the said model being caused to come in contact with this

is finished' the screw F is rotated sufficiently to displace the part carrying the
model and the block to be sculptured, in order to recommence another track, and
so on until the centre or guide point has passed over every portion.
If the model has a large under part, the lengthening pieces I and I are turned
upon the pins so that the model and the material are caused to assume an
inclined position either to the right or to the left, thus permitting the tool to
recess or cut out these under portions.
If the pieces are of large dimensions, they may be placed at a sufficient distance
from the tool B' and from the centre or guide point or piece N, by unscrewing or
slackening the clamping screw f and displacing or shifting the plate G towards
the left (Fig. 2.).
This apparatus may be so arranged as to make at the same time a certain given
number of reproductions, for this purpose all that is required is to arrange upon
the same framing a certain given number of movable arrangements similar to
that which has just been hereinabove described and which is supported upon the
plate G, and to which are communicated simultaneously, by means of any appro-
priate mechanism, the movements of the central arrangement which latter only
is provided with a centre or guide point or piece N, with a screw threaded
spindle F, and with a counter weighted frame C. In this apparatus the move-
ment of rotation is communicated at the same time to all the tools B¹ by a generai
transmission gearing, established upon the entire length of the apparatus and

page_text: which is itself governed by a transmission or by a motor of any suitable
description.
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;-
An apparatus for reproducing model of sculptures, characterized by a framing
having two sides; a grooved wheel or pulley operated by a pedal; a puppet head
of a recessing machine fixed upon one of the side pieces of the framing and
supporting the rotary tool operated by the grooved wheel or pulley to work the
material to be sculptured, a centre or guide point or piece fixed upon the second
side piece of the framing; a frame provided with a counterweight and with two
gudgeons to admit of a rotary movement in a plane vertical to the parts carrying
the model and the material, which parts are arranged on the said frame; a square
threaded screw mounted in the above mentioned frame, and provided with a
crank handle for the purpose of effecting the forward or backward movement of
the hereinbefore mentioned supporting parts, these parts being composed of a
grooved or slotted plate capable of being displaced in a transverse direction to
the frame, of arms pivotally connected to the above mentioned plate and free to
oscillate or rock upon these pivots in order to impart to the two lengthening
pieces which are connected to these arms and which support the model and the
material to be sculptured, a movement in planes horizontal or inclined perpen-
dicular to the vertical planes above mentioned, the said two lengthening pieces
being connected to the two pivoting arms by means of gudgeons which admit of
an inclination in planes perpendicular to the two hereinbefore mentioned direc-
tions, being imparted to the model and the material to be sculptured, jointed
transverse or cross pieces connecting together the two lengthening pieces; lastly
uprights with clamping screws fixed in the grooves or slots in the lengthening
pieces for the purpose of holding in position the model and the material to be
sculptured.
