PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Screening and Crushing Ashes,
Night Soil, Sand, Gravel, or the like.
I, THOMAS PASQUILL of Hope Fold, Atherton in the County of Lancaster,
Foreman Joiner, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object an apparatus for screening sand, gravel, ashes,
night-soil or the like. An important feature of the apparatus is the providing of
a scrubber in conjunction with the screen box, for reducing or breaking up the
material under treatment and screening the same.
In carrying my invention into effect I provide a rocking or vibrating screen
which may be hung from hangers suspended from a frame. One set of these
hangers is jointed in the middle to allow of the lifting or tipping of the screen.
The screen also is preferably placed in a sloping position and is open at the lower
end, to allow of the passage of material which is of too large a grade to pass
through the screen. It is vibrated, and also tipped if desired, by means of an
eccentric mounted on a rotatable shaft or by other suitable device. In the screen
box I place a scrubber, consisting of a framework the sides of which slide on plates
secured to the inside of the box and of rows of chains which are connected to the
framework and run diagonally thereto. The chains are connected to each other
by cross links forming a net.
The scrubber may however be constructed in any other suitable manner and
may be operated from the eccentric, preferably vibrating in the opposite direction
of the screen.
The mode of action is as follows:-
The material is placed on the screen by a shovel or otherwise and is spread by
the scrubber and also crushed and broken thereby. The smaller particles drop
through the screen being assisted in so doing by the vibration of the latter, while
the scrubber rises to permit of the passage of large or hard substances which
cannot be crushed or broken.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Screening and Crushing Ashes,
Night Soil, Sand, Gravel, or the like.
I, THOMAS PASQUILL of Hope Fold, Atherton, in the County of Lancaster,
Foreman Joiner, 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 has for its object an apparatus for screening sand, gravel, ashes,
night soil or the like.
An important feature of the apparatus is the providing of a scrubber in con-
junction with the screen box for reducing or breaking up the material under
treatment and screening the same.
The accompanying drawings illustrate this improved apparatus
Figure 1 being a side elevation with a portion of the screen broken away, and
Figure 2, a plan with a portion of the frame broken away.

page_text: In these-
A, is a rocking or vibrating screen, suspended from the frame A¹ by rods or
hangers B, one set of which is jointed at b to allow of the lifting or tipping of the
screen. The screen is also preferably hung in a sloping position and is open at the
lower end, to allow of the passage of material which is of too large a grade to pass
through it.
The screen is vibrated and also tipped preferably by means of an eccentric C
mounted on a rotatable shaft C', but any other suitable device may be employed.
.D is a hand wheel on the shaft C¹ for rotating the same. E is the scrubber
consisting of a frame E', the ends of which slide on ledges F on the inside of the
screen box A2 and of rows of chains which may be arranged diagonally, but I
prefer them as shown, parallel to the ends of the framework. These chains are
connected to each other by cross links forming a kind of network G, which is
secured to the frame E', at the sides by means of bolts e, and at the ends by means
of bolts e¹ passing through distance pieces e2, Figure 1. The network is left
sufficiently long to allow of its grating on the perforated bottom a of the screen
and to permit of its rising for the passage of large substances. The perforated
bottom a is omitted from the plan for the sake of simplicity.
The scrubber is operated by the eccentric C, being connected therewith by the
rod H shown broken away in the plan, Figure 2. The vibrations of the scrubber
are in opposite directions to the screen, which latter is also operated from the
eccentric C, lugs e c¹ being formed on the eccentric strap, the lower one, c',
operating the screen and the upper one, c, the scrubber. The perforated bottom a
can be of any mesh to suit the material to be screened.
C
The mode of action is as follows:-
The material is placed on the screen by a shovel or otherwise, and, on the
rotation of the hand wheel, is spread by the scrubber and also crushed and broken
thereby. The smaller particles drop through the screen, being assisted in so doing
by the vibration of the latter, while the scrubber rises to permit of the passage of
large or hard substances which cannot be crushed or broken. The lower end of
the frame may be boarded up if required to prevent the screened material mixing
with the refuse.
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. An improved apparatus for screening and crushing ashes, night soil, sand,
gravel or the like, consisting of a screen suspended from a frame and vibrated by
any suitable device, in combination with a vibrating scrubber such as E moving in.
a direction opposite to that of the screen, whereby the material is crushed or
broken and spread over the latter, the smaller particles dropping therethrough
while the larger particles fall over the end of the same, substantially as described.
2. In a screening and crushing apparatus of the kind described, the combination
with the vibrating screen A and scrubber E of means substantially as set forth
. whereby both the screen and scrubber are vibrated in opposite directions by an
eccentric.
3. The general arrangement or construction of parts forming my improved
apparatus for screening and crushing ashes, night soil, sand, gravel or the like,
substantially as set forth.
