page_text: LETTERS PATENT to Charles Chapitel, of the Firm François Durand and
Charles Chapitel, of Boulevard Saint Denis, No. 1, at Paris, for the Invention
of "AN IMPROVED MACHINERY OR APPARATUS FOR BREAKING STONES, ORES,
AND OTHER MATERIALS.
"
:
Sealed the 19th January 1877, and dated the 20th July 1876.
PROVISIONAL SPECIFICATION left by the said Charles Chapitel at the Office
of the Commissioners of Patents on the 20th July 1876.
CHARLES CHAPITEL, of the Firm François Durand and Charles Chapitel, of
Boulevard Saint Denis, No. 1, at Paris. "AN IMPROVED MACHINERY OR APPARATUS
FOR BREAKING STONES, ORES, AND OTHER MATERIALS."
The object of this Invention is to break, during their discharge through the
machine, stones and ores of all kinds. The action of the machine being continuous,
the stones or material to be broken are thrown into a hopper, and a rotary beater
working within a suitably enclosed framework breaks them on their passage (that
is without crushing them against a fixed piece), and the broken fragments are
thrown against an arrangement of iron bars forming a grid or sieve on either side
of the beater. The fragments that are still too large to pass between the bars are
again taken up by the rotary beater and crushed, and so on until they are reduced
to the required size.
The main features of this Invention are--
Firstly. The arrangement within a suitably enclosed framework of a rotary
beater provided with swinging steel hammers jointed to the main portion of the
beater for the purpose of striking and breaking during their passage the stones or
ores which are fed from a hopper or shoot above the machine.
Secondly. The arrangement of an inclined plane or guide for conducting the
broken pieces from the machine to trucks or waggons, and
Thirdly. The arrangement of bars forming a grid or sieve upon which are thrown
the fragments broken by the articulated hammers of the rotary beater.
The rotary shaft carrying the beater is driven by pulley and band or gearing.

CHARLES CHAPITEL, of the Firm of Francois Durand and Charles Chapitel, of
Boulevard Saint Denis, No. 1, at Paris. "AN IMPROVED MACHINERY OR APPARATUS:
FOR BREAKING STONES, ORES, AND OTHER MATERIALS."
The object of this Invention is the construction of machinery or apparatus for
breaking stones, ores, minerals, and generally all substances of a like or similar kind
on their passage through the machine. The action of the machine is continuous.
The stones or material to be broken are thrown into a hopper, and a rotary
beater working within a suitably enclosed framework breaks them on their passage
(that is without crushing them against a fixed piece), and the broken fragments
are thrown over an arrangement of iron bars forming a grid or sieve. The frag-
ments that are still too large to pass between the bars are again taken up by the
beater and rebroken, and so on until they are of sufficiently reduced size to pass
out from the machine between the bars.
The characteristics of this improved machinery are
First. The arrangement within a suitably enclosed framework of a rotary beater
provided with jointed or swinging steel hammers for the purpose of striking and
breaking during their passage the stones, ores, or other material which are fed from
a hopper arranged above the machine.
Secondly. The arrangement of a shoot or inclined plane to conduct the broken
fragments from the machine to trucks or waggons for the purpose of removal.
Thirdly. The arrangement of parallel bars forming a grid or sieve, and on to
which are thrown the fragments broken by the jointed hammers of the rotary
beater.
And, Finally. The general arrangement of apparatus shown and described.
By the Drawings hereunto annexed the arrangement or construction and working
of this improved machine will be well understood.
Fig. 1 is a longitudinal section of the apparatus constructed according to this
Invention; Fig. 2 a transverse section, and Fig. 3 a plan.
The apparatus is composed of an enclosed framework a of wood, of a trough
form, and supported on a foundation or support x, also in wood. The two lateral
sides of the framework a are vertical, and the two ends a¹, a¹, are arranged in an
incliued or sloping direction to facilitate the descent of the fragments of broken
material towards the bottom of the apparatus. This framework is covered in at
the top, at its lateral sides, and bottom with a metallic sheathing to protect samo
from the blow of the broken fragments. Parallel to the sides a¹, a¹, are arranged
the iron bars b, b, forming the grid; they are supported at their base by a support
of cast iron, b¹, furnished with mortises for the reception of the ends of the iron bars,
the which are supported at their upper end by cast-iron plates 6", likewise formed
to allow of their introduction into the machine. These bars are also supported
and guided by the cross supports 6111, secured on the lateral sides of the framework.
The upper part of the framework a is furnished with a hopper c, in which is
thrown the matters to be broken; the bottom d is formed by the support 61, and
below this latter is arranged the shoot or incline f by which the broken particles
are conducted from the machine. The rotary beater g is formed of a cast hub of
an oval form, and cut away at g', gl, as seen in Fig. 1, to allow of the play of the
two tempered steel hammers h, h, jointed on the axes l, l, which pass through the
hub. This beater is mounted on a central shaft i, carrying on one side the driving
pulley and at the other the regulating fly wheel .
A speed of from 800 to 1000 revolutions per minute is communicated to the
shaft either by means of any suitable means of transmission or by that shown in
the Drawings. This latter is composed of fast and loose pullies 3, j, and of another
pulley of a diameter twice that of the pulley i, to which the rotary motion is

page_text: communicated, the three pullies j, j, and m are mounted on the shaft n, supported
by the blocks o, o.
The action of the machine is as follows:-After having started the machine at
the speed above specified, the materials to be broken are thrown into the hopper c,
and these on leaving said hopper are broken on their passage by the jointed
hammers h, h, of the rotary beaters g, and by reason of the enormous velocity they
are broken to pieces. Their reduction is completed by the throwing of the pieces
against or over the bars, rebounding on the support b', and being again taken, up
by the beaters, which effects their complete reduction.
The result of the breaking, that is, the crushed material, escapes through the
bars b, b, and falls into the bottom of the machine on the shoot or incline f
which conveys them away to the trucks or waggons destined for their removal.
The rotary beater may be arranged so that the jointed hammers act vertically
or horizontally for breaking the stones or materials falling from the hopper.
Having now described the nature and particulars of my said Invention, I claim
the use of the improved system of rotary machinery destined to effect the reduction
of ores, stones, and other materials, substantially as herein described, such machinery
being characterised by the following principal features:-
First. The combined arrangement of a rotary beater driven at a high velocity
and furnished with jointed steel hammers, which break on their passage the
materials falling from the hopper.
Secondly. The arrangement of the shoot or incline for the discharge from the
machine of the broken fragments, substantially as herein described.
Thirdly. The arrangement of moveable and parallel bars forming a grid, and on
to which are thrown the fragments of stone or other material broken in their
passage by the hammers of the rotary beater.
And, Finally. The general arrangement and construction of the improved machine,
the which may be varied as to dimensions and requirements for the purpose of
its application to the reduction and crushing of materials generally, substantially
as herein described and set forth.
In witness whereof, I, the said Charles Chapitel, have hereunto set my hand
and seal, this Eighth day of January, One thousand eight hundred and
seventy-seven.
