PROVISIONAL SPECIFICATION.
Improved Sand-making and Stone-knapping Machine.
We, HERBERT William Clarke, Accountant and JAMES EMERY Engineer-
both of 66 Crayford Road, Erith in the County of Kent, do hereby declare the
nature of this invention to be as follows :-
--
This invention relates to a machine for making sand from flints, stones, granite,.
clinker or similar substances or knapping same to special sizes. It consists of a.
wrought iron or steel frame, bolted to a hard wood base by holding down bolts, in.
which frame are worked a pair or more of chilled iron or steel rollers either grooved
or plain working into each other by internal and external motion each roller being
fitted with a dy wheel and driving pulley and working in a cast iron or steel sliding-
block adjustable to the frame, such sliding blocks being set by intermediate plates.
to the size required by an adjustable set screw. A protecting plate is used for
roller bearings and a hopper with adjustable plates to suit feed.

We, HERBERT WILLIAM CLARKE, Accountant, and JAMES EMERY, Engineer,.
both of Crayford Road, Erith, in the County of Kent, 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 make sand from flints, stones, granite, clinker,.
or similar substances, and to crack the last mentioned materials to any required
sizes. The machine by which we effect these objects consists of a wrought-iron or-
steel frame bolted to a hard-wood or metal bed by holding down bolts the whole
being supported on a concrete brick or wooden base; or foundation. The frame is.
provided with one or more pairs of chilled iron or steel rollers (the surfaces of
which may be either grooved, corrugated or plain) revolved towards each other by
any suitable means such as by providing each roller with a shaft (carrying a
fly-wheel and driving-pulley) working in cast-iron or steel sliding-blocks adjustable
to the frame; the said sliding blocks being set by intermediate plates to the sizes
required, and held in position by adjustable sorews, a protecting plate being
provided for the bearings of the rollers, and a hopper with adjustable plates to.
regulate the feed.
In order to render the nature of our invention clearer we make reference to the
accompanying sheet of drawings in which Fig. 1 is a plan Fig. 2. a longitudinal
section through A. B Fig. 1 and Fig. 3 a transverse section through C. D. Fig. 1.
a wrought iron or steel frame; b rollers; with grooves; corrugated or plain
surfaces; e shafting of rollers; & fly-wheels; e riggers for driving; f bearing for
rollers i blocks for carrying the screws by which the rollers are adjusted;

page_text: adjustable screws; i lock nut; j holding-down bolts; foundation; hopper
with internal plate l' (extending from side to side of the hopper) for adjusting feed;
m timber bed slides through which pass bolts attached to 1, & provided with
nuts a' by which the plate can be kept at any distance from the ends of the slots
for moving internal plate to regulate feed of hopper; o adjustable plates for setting
rollers at required distances apart; p protecting plate for bearings of rollers. The
uction of the machine is as follows:-
The boulders, spalls, stones etc., to be reduced are taken of suitable size and
placed in the hopper and the rollers set at such a distance apart as will permit of
the stones or the like being carried through. After having passed the material
through the rollers we either pass it through a sieve, screen or suitable separator,
or through the same or another set of rollers until we get it reduced to the required
size. By these means we can reduce material down to sand or powder or to any
other sizes we may wish.
We do not confine ourselves to the precise shape configuration or disposition of
the relative parts of the machine as described in the Specification or exemplified
in the accompanying drawings as any or all of them may be considerably varied
without departing from the invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. An improved sand making and stone knapping machine consisting of rollers
of chilled iron or steel having their surfaces either grooved, corrugated or plain,
and fixed in a wrought-iron or steel framing with bearing blocks, adjustable by set
screws, and distances plates, and having protecting shields for the bearings sub-
stantially as described in the above Specification and exemplified in the accompanying
drawings.
