Improvements in Machinery for Triturating and Crushing Substances.
I HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents
of 18 Buckingham Street, Strand W.C. in the County of Middlesex, Civil Engineer
do hereby declare the nature of this invention, a communication to me from abroad
by Jaime Planas y Rodoreda and Erasmo Puig y Rodriguez both of Calle de Pino
13, Barcelona in the Kingdom of Spain, Engineers, and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :—
This invention relates to machinery for pulverizing substances. The improvements
are performed as hereinafter described reference being had to the drawings.
Through a funnel A the substance to be pulverized is introduced; when it is
worked upon by the triturating or pulverizing cylinders B. B¹ which are made of
grooved facetted surfaces or channels formed with hollows, slits or any other arrange-
ment which will form teeth of variable shape.
The projecting parts of one of the cylinders gear into the recesses of the other and
one of the two cylinders viz. B¹, rotates quicker than the other, B, that is to say B is
the carrier of the substance to be triturated, and the other B¹ is the actual triturating
cylinder which acts upon the substance to be operated on in the same manner as a file
by scraping. The proportions of these two speeds vary according to circumstances.
The cylinder B can be moved more or less towards the cylinder B to obtain a
more or less fine product. To do this a mechanism as indicated in the drawings can
be employed, which is operated by a screw pressing against the bearings of the
cylinder B which are thus moved away from the cylinder B. These bearings are
pressed on by the springs R which are so arranged as to advance towards the
cylinder B by the action of the spring the pressure of which can be regulated by the
screw S which passes through the nut into which the end of the spring is fastened.
By this arrangement the teeth of the cylinder are prevented from breaking through
the introduction of a body which is harder than the power given to the springs, for
the cylinder B' moves away from B without triturating the same and without breaking
its teeth.
The crushed product is collected in a case M or into sacks or baskets according to
the importances of the manufacture.
The machine can be put into motion by any motor by putting up the necessary
gearing.
The necessary casing is provided for preventing the accidental throwing out of the
product at the sides of the machine.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
In machinery for triturating or crushing.
1. The grooved cylinders B. B₁ formed with recesses grooves and facets etc.
forming teeth for gearing one with the other.
2. The machinery consisting of the grooved or toothed cylinders working in pairs
at different speed, one at less speed for carrying the product or substance and the
other for scraping the substance to pulverize it.
3. In machinery having cylinders made as above described one cylinder arranged
to move away from the other by mechanical means for obtaining a more or less fine
trituration.

page_text: 4. In machinery having the above described cylinders the springs R arranged to
prevent the breaking of the cylinder teeth. All substantially as illustrated and
described and for the purposes set forth.
