Improvements in Crushing Machines for Anthracite, Coke, Charcoal,
Schists, and other Minerals.
I, FRANÇOIS FELIX DEPEAUX, of 25, Boulevard Cauchoise, Rouen, in the
Republic of France, Ship Owner, 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:-
The object of this invention is to increase the output of the machine, and at the
same time to lessen to a very great degree the production of waste, that is to say,
of powder and small pieces.
I also obtain greater stability, strength and durability in the machine.
The accompanying drawings represent one of the methods of carrying out my
invention.
on
Figure 1 is a front elevation of the machine, Figure 2 a vertical section
the line A B (Figure 1), and Figure 3 a horizontal section on the line C D
(Figure 1).
The frame E carries two bearings F F in which the driving shaft G rotates,
this shaft carries the driving pulley H, a fly wheel V, and a spur wheel I.
This spur wheel gears with a toothed wheel I' keyed on the crank shaft K. This
shaft rotates in bearings L L' and by means of the connecting rod M gives a
reciprocating motion to the cross head N working between two parts 001 of
the frame, forming guides. At the lower end of the crosshead N is fixed, by
means of a strong bolt, the piece N to which the plate P carrying the punches P¹
is fixed by several bolts.
Lastly the plate Q serves to receive the substance to be crushed; it is pierced
with a given number of holes of suitable size exactly corresponding to the number
and arrangement of the punches P' which divide up the substance. It is the
adoption of this grid instead of a solid plate as in former machines which forms
the main improvement. As soon as the pieces have attained the required size
they fall through the grid and thus escape subsequent action of the punches
which would otherwise reduce them too small and to powder. From this fact a
great diminution in wastage will take place and consequently also a corresponding
increase in the output of the machine.
I obtain a greater amount of work in the same time by the fact that the machine
being of stronger construction, is capable of resisting a greater shock thus allow-
ing a greater number of points to be given to the plate P.
The substance to be crushed may be automatically fed between the grid and the
5 punches by means of an endless band working over rollers. The crushed sub-
stance after having passed through the grid Q falls upon a grading machine which
divides it into as many sizes as desirable.
One of the chief advantages of a crushing machine constructed in accordance
with my invention is the rapidity with which I am able to alter the size of the
10 products crushed, it being only necessary to change the grid Q and the plate I
which carries points corresponding to the holes in the grid.

page_text: 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:
1. In a crushing machine for anthracite, coke, charcoal, schists and other
minerals the use of a pierced plate, forming a grid, as support for the substance to 5
be crushed.
2. The apparatus substantially as described and shown in the drawings.
Dated this 26th day of June 1899.
