Novel or Improved Apparatus for Use in Sifting Potters' Slip,
and Method of Driving or Working same.
We, Joux EDWARD JOSEPH BAXTER, Phoenix and Bell Works, Broad Street,
Hanley, Earthenware Manufacturer, and GEORGE EDWARD SIMPSON, 84; Cecil
Street, Cobridge, Engineer, both in the County of Staffordshire, do hereby
declare the nature of this invention to be as follows:-
"
This our invention has reference to a novel or improved apparatus and method
of driving same chiefly intended for use in sifting potters slip," the object
of our said invention being to reduce, size, weight, wear and tear in working
such machines or apparatus, and cost of building or constructing same.
In carrying our said invention into practice we make a square or rectangular.
wood framing or casing of suitable thickness, width and length with open ends,
within such casing we erect a wood, or a wood and metallic perpendicular post
or pillar of suitable cross-section having a steel, a gun-metal or other suitable
metallic lower end for bearing in or upon a brass, a bronze or other suitable
footstep-bearing, the upper and lower ends of such pillar passing through a
circular shaped aperture in a wood, a wrought-iron or other suitable strap or
rod connecting the sides of such casing, the upper end of such perpendicular
post or pillar also passing through a suitable eye-bearing or steady, the opposite
end of the wrought-iron or steel, rod or bar in which such eye-bearing is mounted
or fixed being bolted or attached to a wall, a post or pillar or other suitable place
for maintaining such apparatus in an upright position, to each side of the per-
pendicular pillar or post of such apparatus we fit or fix a vertical or nearly
vertical suitable wood-board so as to extend from the lower end of its casing
or framing to within a short distance of the upper end of such framing so as to
divide the space within such wood casing into four or more compartments or
divisions, to each side of such vertical wood division boards at a suitable dis-
tance apart we fix a suitable number of horizontal suitably shapeil wood ledges.
or strips for enabling the lower side edges of rectangular or square removable
wood-framed "lawns or sieves to rest or bear thereon, and secure such " lawns"
on such ledges within such compartments by means of hinged doors fitted with a
wood, a metallic or other suitable button, bolt or fastening, so that two or more
"lawns" will be supported above each other in each compartment by such ledges.
To the upper end of the casing or framing of such apparatus and top edge
of one division board we attach by screws, nails, bolts or the like a wrought-iron,
a steel or other suitable metallic strap or bar of suitable width and thickness,
so as to extend from the central or perpendicular post to a suitable distance
beyond one side of such casing, to the upper end of the said perpendicular or
central post we fit or fix one end of a wrought-iron, a steel or other strap or
bar of suitable width and thickness, the outer end or portion of such bar or strap
being downwardly curved or bent, and bolted, rivetted or otherwise connected to
the outer or projecting portion of the metallic bar or strap below same fixed to
the upper end of the said casing. On or to the upper surface of the outer end
of such lower or projecting metallic strap we attach fit or fix a suitably shaped
22

page_text: brass or other metallic swivel-bearing to which we connect by a steel, a wrought-
iron or like suitable metallic pin, ond end of a suitable connecting-rod, the
other or adjustable end of such rod being fitted on or to the projecting-pin of.
an excentric plate, to an excentric, or to the cranked portion of a horizontal or
vertical driving shaft having a friction clutch fitted thereto, or a fast and loose
pulley thereon.
When such friction-clutch is thrown into gear, or a driving-band or strap
shifted from the loose pulley on to the fast-pulley on such shaft a vibratory
motion will be imparted to such vertically mounted appliance or sifter, the
slip" which falls on to the top "lawn" in each compartment of such apparatus
being conveyed thereto by a wood trough or troughs having any suitable number
of holes through its or their bottom side, and fixed or suspended at a suitable
height above such apparatus, the "slip" flowing or percolating through the top
sieves on to and through the lawns" beneath same into a wood-framing or
tray from whence it drains or flows through any suitable number of holes or
apertures into an ark or other appliance for further treatment.

"
The lawns used with such sifters may all be of equal mesh, or the upper
lawn" in each compartment of such appliances may be of one mesh, and the
lawns" below same of finer mesh.
By using such improved and reduced size of "sifters," and the method of
driving same we find a considerable reduction in the
wear and tear, facility in repairing such apparatus, and use of construction, in
"
production of an equai
if not a greater amount of sifted slip," than when using a "sifter" of ordinary
construction and larger size driven or worked by reciprocating-motion.

Novel or improved Apparatus for Use in Sifting Potters' Slip,
and Method of Driving or Working same.
We, JOHN EDWARD JOSEPH BAXTER, Phoenix and Bell Works, Broad Street,
Hanley, Earthenware Manufacturer, and GEORGE EDWARD SIMPSON, 84, Cecil
Street, Cobridge, Engineer, both in the County of Staffordshire, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This our invention has reference to a novel or improved apparatus and method
of driving same chiefly intended for use in sifting potters "slip," the object
of our said invention being to reduce size, weight, wear and tear in working
such machines or apparatus, and cost of building or constructing same.
In order that our invention may be readily understood and explained in detail
we have hereunto annexed a sheet of drawings on which letters of reference are
marked.
DESCRIPTION OF DRAWINGS.
Figure 1 is a side elevation of our improved apparatus made according to our
invention, and
Figure 2 is a plan view of Figure 1.
On reference to the drawings hereto annexed a represents a square oak or like
suitable wood casing or framing divided into four divisions by wood partitions

page_text: c of
within which framing we centrally fix a wrought-iron, or steel post or pillar
suitable transverse section having a cylindrical upper portion and a suitably
shaped lower end for bearing in or upon a brass, a bronze,, a gun-metal or other
suitable metallic bearing d such shaft passing through a suitably, shaped aperture
formed in a wrought-iron, .or. steel strap or bars e fixed or bolted to the top
surface of the wood partions for strengthening such wood framing, the upper
end of such shaft passing through a suitable eye-bearing f formed on. or within
a suitably shaped cast-iron or forged iron steadying-bracket g bolted or securely
attached to a wall or to a suitably shaped beam, post or pillar for keeping such
shaft, post or pillar and the framing attached or fixed thereto upright."
The lower sloping surface i of each compartment formed in each division of
the said framing a having a square or other suitably shaped aperture formed
in same so that "slip" may flow or descend down through thd several compart-
ments and sieves placed in same into the space enclosed by the wood framing k
beneath the framing a fixed to the upright shaft or pillar c.
Within each compartment in such framing a we place a removable wood-framed
lawn or sieve and secure same therein by means of wood-flaps or wood strips m
hinged to the framing a kept in position by a wood, a metallic or other suitable
button, bolt, fastening or catch.
"
After such framing a with its several sieves or lawns is vibrated or set in motion
by means of a driving band or strap passing around the fast pulley fixed on the
shaft or by means of a friction-clutch fixed on such shaft, slip" to be sifted
will be conveyed by the wood trough o into the wood troughs p, fixed or sus-
pended at a suitable height above such apparatus to permit such slip" to flow
or pass through a hole or apertures formed in their bottom side or surface on
to the top lawn in each compartment of such framing a, the "slip" by the
vibratory motion imparted being caused to readily percolate through the top
sieves on to and through the lawns or sieves beneath same into the enclosed or
surrounded spaces having a flat, or preferably an inclined surface from whence
it drains or Hows through a suitable hole or apertures formed in the framing k
into a suitable wood trough or troughs t which conduct such sifted slip into an
ark or other suitable vessel for further treatment. By means of the wood slides
or gates u in the troughs p, q, and the wood slide or gate in the trough
flow of the "slip" to the uppermost lawns can be regulated or stopped.
the
The vibratory motion being imparted to such framing or sieve-holder by a con-
necting rod fitted or connected at its outer end to the vertical metallic pin c
fixed or bolted to the outer end of the strap or bars e whilst the inner end of such
connecting-rod is fitted on or to the projecting-pin of a metallic crank-plate y
fixed at the end of the shaft n, the dotted lines and y² shewing where the
driving shaft may be fixed if desired.
The framing of such appliances may be rectangular, pentagonal, hexagonal,
octagonal or other suitable shape in transverse section with any suitable number
of lawns or sieves of suitable shape in each division directly above each other at
any desired distance apart, each lawn consisting of a wood framing with a siero
at its lower side of the usual make employed, and may all be of equal mesh or
the top most lawn in each division may be of one mesh and the lawns or sieves
below of finer mesh.
By using such improved and reduced size of sifters and the method of driving
same we considerably reduce the expense of wear and tear, facilitate repairs
thereto, and produce an equal if not a greater amount of sifted "slip" than when
using a sifter of ordinary construction and larger in size driven by reciprocating
motion.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
Appliances or sifters for potters' use consisting of a wood framtins divided by
.

page_text: wood partitions into two or more divisions and each division into any suitable
number of compartments in which removable lawns may be placed and secured.
directly above each other at a suitable distance apart which appliances when
worked have a vibratory motion transmitted thereto and arranged in the manner
and for the purpose as herein substantially described and set forth.
