An Improved Apparatus for Making Sculptured Images or Works
of Art.
A communication by AUGUSTO BONTEMPI, of 11 Via Pippo Spano, Florence
in the Kingdom of Italy, Lieutenant in the Italian Army.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street,
Manchester, both in the County of Lancaster, 118 New Street, Birmingham
in the County of Warwick and 322 High Holborn in the County of Middlesex,
Civil 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 :-
This invention has for its object an apparatus by which sculptured images or
works of art may be made from a model. This apparatus is characterized essentially
by the various devices being concentrated at one place, and being capable of being
operated by one person.
The object of the invention is shown in the accompanying drawings, in
which-
Figure 1 is a front view of the apparatus ;
Figure 2 a horizontal section on the line a-b of Figure 1;
Figure 3 shows the standards from which the movement of the various parts
takes place;
Figure 4 shows a portion of Figure 3 seen in the direction of the arrow c;
Figure 5 is a plan view of the support of the working tool or steel;
Figure 6 is a further form of construction of the frame necessary for holding the
sculptured images or works of art.
The constructive arrangement is as follows:-
Two supports or standards 2 are adjustably arranged on two slide ways 1
standing opposite one another, and these two frames or supports are connected with
one another by means of a screwed spindle 5 mounted in a support 3 and provided
with a chain wheel 4, so that by revolving said screwed spindle in one direction or
the other, the two supports or frames 2 may be moved mutually to left or right.
The upper end of each support carries a guide bar 6 intended to support the main
frame 7. For this purpose the latter is provided with angle bars 8 which serve as
guides and partly enclose the guide bars 6. A vertically adjustable frame A is
mounted in the framework 7, and consists of two crossbars or beams 9 and 10,
inner vertical guide bars 11 and side racks 12. A second horizontal beam 13 is
mounted on the bars 11 and racks 12 and may have its height varied by means of
pawls 14 arranged on it so as to engage in the racks 12. The frame A is thus
divided into three vertical divisions or compartments which serve for holding the
model 15 and the works of art or images 16 which are to be made.
In order to be able to fix in the frame the model and the rough blocks for the
images which are to be made, the crossbar 13 is provided with set screws 17 which
have at their lower ends a spiked holder 18, whilst the lower crossbar 10 is provided
with supports 19. These supports 19 consist of a crown holder connected to a
worm wheel 21 revoluble on studs 20.
A worm shaft 22 is also mounted in the frame A, so that the worm wheels 21
may be thereby operated, and the model 15 [and the blocks 16 thus rotated
evenly on their vertical axes.

page_text: The frame A may be counterbalanced by counter-weights, connected with
chains 23 travelling over pulleys in order to facilitate the vertical movement of
the said frame. Owing to the crossbars 13 being vertically adjustable, models
and images of various heights may be fastened in the frame. As however both
the copying point and also the working steel or tool do not alter their position,
it is necessary that the model and also the images may be able to be rotated in
the frame on their axes, and this is rendered possible by the arrangement of the
aforesaid supports 19 and worm shaft 22, and it is also necessary that the frame A
should be vertically adjustable in the framework 7, and the framework 7 hori-
zontally on the supports 2, and the whole in another horizontal direction on the
slideway 1.
In order to effect all this, the following arrangement is adopted:
. The lower crossbar 10 of the frame A is provided with a slide guide 24, in which
a screw nut 25 may be adjusted in the direction of the arrows 26 and 27. As
shown in Figures 2 and 3 a stand 28 is arranged behind the whole framework,
which stand carries a fixed vertical screwed spindle 29. On this screwed spindle,
the upper end of which carries the adjustable copying point 30, a support or
frame B slides which carries a horizontally arranged screwed spindle 31, which
engages in the screw nut 25 (Figure 1). In order to render possible a vertical
adjustment of the support B, and therewith of the frame A. with the model 15 and
the images 16, the support frame is provided with a sleeve or socket 32 (Figure 4)
which loosely surrounds the spindle 29 and carries a spline 34 corresponding with
a groove 33 in the screwed spindle 29. A bevel wheel 35 is inserted between the
sleeve 32 and the upper part of the support frame, and the nave of said bevel
wheel is formed as a screw nut and engages the screwed spindle 29. By turning
this bevel wheel, a vertical adjustment of the whole support B is obtained. In
order however to render possible an even rotation of the bevel wheel a second
bevel wheel 36, to engage the former, is mounted in the support frame, and may be
operated by means of a crank handle 37. The screwed spindle 31 is revolubly
mounted in the support frame, and the inner end of the same carries a bevel
wheel 38 standing in engagement with a bevel wheel 40 (Figure 4) which is also
mounted in the support frame and provided with a crank handle 39, so that by
moving the crank 39, a rotation of the screwed spindle 31, and thereby the adjust-
ment of the frame 7 in the supports 2 in the directions of arrows 41 or 42,
respectively may he effected (see Figures 2-4).
Thus by operating the crank 37, a vertical adjustment of the frame A, and by
operating the crank 39, a horizontal adjustment of the frame 7, is effected. In
orler, however, to be able to operate the screwed spindle 5 (Figure 1) for adjusting
the whole system from the standard or support 28, a chain wheel 43 is mounted in
the latter which is connected with the chain wheel 4 by means of a chain 44. The.
axle of the chain wheel 43 is provided with pedals 45 to be operated by the person
using the apparatus in the same way as bicycle pedals. The stand 28 is also
provided with a scat 46 on which the person using the apparatus can place himself.
The necessary borers or tools for making the image are mounted behind the
frame in the plane of the copying point 30, and in a frame 47 composed of two
movable parallelograms. (see Figure 5) The front of this frame is intended to
receive a revoluble sleeve or socket 49 provided with a borer 48, whilst in the rear,
spindles 50 carrying pulleys 51 are mounted corresponding with the sockets 49 and
carrying the same with them when rotated.
The parallel shaped frame has for its object to allow of the various borers 48
being simultaneously and equally adjusted on their axes, whilst preventing any
sideways adjustment of the same, and this is effected by the said frame being
pressed together or collapsed.
In the form of construction shown in Figure 5, the rear of this parallelogram
is presumed to be fixed and all the other parts to be movable but the case may
be reversed so that the front may be fixed and all the other parts remain
movable.

page_text: As however it may happen with certain images that they have recessed parts or
hollows widening inwards, for the making of which the vertical and horizontal
movement does not suffice, it is necessary that the frame A must be capable of
being oscillated on its horizontal axis. Figure 6 shows such an extended form of
construction.
A frame 52 is arranged so as to be vertically adjustable in the framework 7 and
receives the frame A oscillating on trunnions 53. A slide guide 24 is mounted
on the frame 52, otherwise the frame A is arranged exactly like that described in
Figure 1.
The mode of operation of this apparatus is as follows:-
The blocks 16 which are to be treated and the model 15 are gripped in the
frame A, and the borer 48 is set in rotation. The person using the apparatus then.
sits on the seat 46 and effects the adjustment of the frame A, or the said frime
together with the frame 7, in such a way that the copying point 30 comes in
contact with the model. The borers 48 work up to this depth on the blocks 16.
and reproduce in this way the plastic characteristics of the model 15. If an
adjustment or shifting of the entire device becomes necessary, the person using the
apparatus operates the pedals 45 so that the screw spindle 5 comes into action.
If the models have recesses widening inwards, the frame shown in Figure 6 is
inserted in the framework 7, so that it is possible to allow the model and the
images to also oscillate on a horizontal axis, and thereby to reach or have access to
all the inner spaces of the model.
Reproductions of images on a larger or smaller scale may also be produced with.
this apparatus.
For this purpose two apparatuses must be placed side by side or one behind the
other, and the screwed spindles of the one apparatus must stand t those of the
other apparatus in a suitable proportion for increasing or diminishing the size..
In such a case only one apparatus will contain the model, whilst the other is.
intended for receiving the image or work of art which is to be produced.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. An apparatus for making sculptured images or works of art, characterized
by frames (7 and A) for holding the model and images being arranged so as to be.
vertically and horizontally adjustable by the operation of a support (B) from one
place by means of two cranks (37 and 39) and by the whole frame system being
adapted to be moved together with the guide supports into a suitable position, by
the operation of a screwed spindle (5) by means of pedals (45), whereby only
one person is necessary for operating the whole apparatus, substantially as herein-
before described.
in
2. In an apparatus such as described, the system of frames (7 and A) adjustable
one another and arranged in horizontally adjustable guide supports or
standards (2) one frame (A) being provided with supports (19) for the reception
of the model and images and with a worm shaft (22) for adjustment of the latter
supports and having a slide guide (24) in which is mounted a guide nut (25)
connected with the frame supporting device (B) whereby the points of operation
for all movements of the frame are concentrated at one place substantially as.
described.
3. In an apparatus such as described having a system of frames a form of
construction of the frame A, consisting in arranging the same in such a way as to
oscillate in a second frame 52 adjustable in the frame 7, with the object of
permitting the model and images to be inclined to an acute angle to the axis of
the working tool for the purpose of working out inner hollows or recesses
substantially as described.
4. In an apparatus such as described the arrangement of a support (B), adapted
to be vertically adjusted on a fixed screwed spindle (29) by means of a crank (37).

page_text: and bevel wheel gearing (35 &.36) and carrying a screwed spindle (31) revolubly
mounted therein and engaging a guide nut (25) mounted in a slide guide (24) and
adapted to be operated by a crank (39) whereby a vertical adjustment of the
frame A and a horizontal adjustment of the same together with the frame 7 may
be effected from one place substantially as described.
5. In an apparatus such as described, the connection of the two guide supports
or standards (2) by means of a screwed spindle (5) provided with a chain
wheel (4), said screwed spindle being connected with a chain wheel mounted in a
support (28) and adapted to be operated by an arrangement of pedals (45) whereby
a horizontal adjustment of the entire system from one and the same central point
may be effected substantially as described.
6. In an apparatus such as described the arrangement of a support for the
working tool or steel, consisting of a framework (47) composed of two parallel
frames, one longitudinal side of which is fixed, whilst all the other parts are
movable, and one longitudinal side of which carries a borer or tool (48) so that by
shutting up or compressing the parallelogram an adjustment of the borer but only
in its axial direction can be effected, substantially as described.
