PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Pulverizing and
Sifting Salt.
1, GEORGE APPLEYARD of 52 Call Lane, Leeds in the County of York, Salt
Merchant, do hereby declare the nature of this invention, to be as follows :-
The object of my invention is to dispense with hand labour and the ordinary
system of crushing under heavy rollers usually employed in reducing or pulverizing
salt from the block.
In bearings on suitable framework I mount a roller or cylinder which is roughed
on the periphery or raised in the manner of a "grater," also at a suitable angle to
this is or are provided another roller or rollers or cylinders having roughed surfaces.
Over these rollers is provided a hopper into which salt in lumps is passed, and at the
bottom of such hopper it comes in contact with the aforesaid rollers and in so doing
is gratered or ground down to a powder, from thence it passes onto a sieve through
which that portion which is sufficiently small passes and into a spout or conductor
which deposits into a sack or other receptacle. The other portions which do not
pass through the sieve are returned to the hopper for the purpose of being reduced to
the proper size.

Improvements in Machinery or Apparatus for Pulverizing and
Sifting Salt.
I, GEORGE APPLEYARD of 52 Call Lane, Leeds in the County of York Salt
Merchant, 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 my invention is to dispense with hand labour and the ordinary
system of crushing under heavy rollers, usually employed in reducing or pulverizing
salt from the block.
In the accompanying drawings Fig. 1 is an end elevation. Fig. 2 a side elevation,
and Fig. 3 an enlarged view of cylinder and parts connected therewith. In bearings A
on suitable framework B I mount a roller or cylinder (which is roughed on the
periphery in the manner of an ordinary grater. At a suitable point or angle to the
cylinder C I suspend an adjustable plate D which is also roughed in the manner of an
ordinary grater; or when preferred an adjustable roughed roller may be employed
instead thereof. Above the roller or cylinder C and on the framework B is mounted a
hopper E into which the salt is passed in lumps, and at the bottom of such hopper E
the salt comes in contact with the roughed cylinder Cand also passes between it and the
adjustable plate D, in so doing the salt is gratered or ground down to a powder; from
thence it passes onto a sieve F suspended on the framework B under the cylinder C,
and through it that portion thereof which is sufficiently small passes and onto a spout
or conductor G, which directs it into a sack or other receptacle.
Those portions which cannot pass through the sieve move down the incline plane
of the riddle away, and are again put through the gratering or pulverizing process.
A shaking motion is imparted to the sieve F by means of a cam or eccentric H
through suitable arm or connecting rod I and gearing J.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The general arrangement, construction and combination of the various parts
forming the apparatus for pulverizing and sifting salt, substantially as herein set
forth.
