PROVISIONAL SPECIFICATION.
Improvements in Machines for Pulverizing and Sifting Salt
and like Substances.
I, GEORGE APPLEYARD, of Call Lane, Leeds, in the County of York, Salt Mer-
chant, do hereby declare the nature of this invention to be as follows:-
This invention refers to apparatus for pulverizing and sifting salt, and my
object is to so construct the same, that the salt is granulated in a more uniform
and regular manner than heretofore.
According to my invention, I employ a framework which supports a hopper
for receiving the salt to be pulverized, and at the base of the hopper a grating
cylinder is provided for the purpose of grating the salt between its surface and
the side of a roughened plate situated in the hopper. Below the grating
cylinder I mount a pair of rolls which are geared together so as to rotate at
the same speed, and motion is imparted to these rolls by means of spur or other
suitable gearing from the shaft carrying the grating cylinder. The salt is
thus first grated by the grating cylinder and it then falls down between the
rolls, where the larger particles become crushed, and the disintegrated salt after
being separated into two or more grades of fineness by a sieve situated below
the rolls, is led off by spouts to sacks or other receivers.

Improvements in Machines for Pulverising and Sifting Salt
and like Substances.
I, GEORGE APPLEYARD, of Call Lane, Leeds, in the County of York, Salt Mer-
chant, 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 refers to apparatus for pulverising and sifting salt, and my
object is to so construct the same, that the salt is granulated in a more uniform
and regular manner than heretofore.
In order that my invention may be readily understood I will describe same
with reference to the accompanying drawings in which Figure 1 is a side eleva-
tion and Figure 2 an end view, of a machine constructed according to my inven-
tion, and Figure 3 is a cross sectional view of the machine.
According to my invention, I employ a framework A, which supports a

page_text: hopper B for receiving the salt to be pulverised, and at the base of the hopper B
a grating cylinder C is provided for the purpose of grating the salt between its
surface and the side of a roughened plate D situated in the hopper B. Below
the grating cylinder C, I mount a pair of rolls E E which are geared together
by spur wheels E2 E2 so as to rotate at the same speed, and motion is imparted
to the rolls E E' by means of toothed wheels F F; the wheel F being mounted
upon the shaft which carries the grating cylinder C, and the wheel F¹ being
carried upon the axle of the roll E. Located below the rolls E E¹ is a sieve H,
fitted with a vibrating device J which derives its motion through the medium
of bevel gear wheels K K. A single shoot L is shown in the drawings, and
the mesh of the sieve H is indicated as of even formation; however, the sieve
may be of compound formation, having a series of different sized meshes, in
which case several shoots would be employed in order to direct the delivery
of different grades of salt.
The salt to be treated is placed in the hopper B, where it is acted upon by
the grating cylinder C and the roughened plate D, from whence it passes to the
rolls E E', where the larger particles become crushed, and the disintegrated
salt falls upon the sieve H, the finer particles passing through to the delivery
shoot L while any residue would tail off the end of the sieve, and be collected
in any suitable manner.
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. Machines for pulverising and sifting salt and like substances, having a
grating cylinder and roughened plate arranged within a hopper in combination
with two rolls, a vibrating sieve and shoot arranged and acting substantially as
herein set forth.
2. The combination of parts constituting my invention in machines for pul-
verising salt and like substances, arranged and acting substantially as and for
the purposes herein before described with reference to the accompanying draw-
ings.
