We, JOHN CUTHBERT BAILEY Earthenware Manufacturer, and' HENRY
PODMORE, Potter's Foreman, both of Nile Street Works; Burslem; Staffs, do
hereby declare the nature of this invention to be as follows:-
This our invention has reference to apparatus or appliances for use in sifting
" of which are
potter a slip, more especially those machines the sieves or "lawns
mounted upon trays or their equivalent, and driven or worked by, reciprocating
motion, such as those described in the Specification of our invention No. 12584
of 1892, the object of our present invention being to dispense with interior sliding
or bearing surfaces for the " trays" of such machines, and 'to' mount such “trays,”
so, as to prolong their life or period of use, and thus obviate the frequent renewal
of same..
Our improved method of mounting the "lawns" or sieves of such machines upon
their trays is by rigidly fixing or attaching a block or strip of wood of suitable size
on the upper surface of and at the rear end of each' tray, the inner edge or side of
each block being curved to fit against a "lawn when in position, a similar shaped
block being fitted to the upper surface of the front end of each tray, and having
two slotted apertures formed through same so that such blocks can be readily
adjusted to fit against the "lawns or sieves.
"
On the underside of each. tray near to the edge of each side we rigidly attach by
bolts or other suitable means a metallic plate of any suitable length, width and
thickness, at a suitable distance from each end of, such metallic plates we weld, or
connect by any suitable means a metallic bolt or shaft of any suitable size, so that
such bolts or shafts will project a suitable distance beyond the sides of such trays
through a slot or aperture formed in each side of the sifting-box, the outer end of
each bolt or shaft resting in or upon suitably shaped metallic slide-blocks supported
by a suitably shaped metallic slide bolted or otherwise attached to each outer side
or surface of the sifting-box, so that the bearing surfaces or slides can be readily
renewed or repaired, and " slip" prevented from getting on to such wearing
surfaces.

or Machines.
We JOHN CUTHBERT BAILEY Earthenware Manufacturer, aud. HENRY
PODMORE, Potter's Foreman, Nile Street Works, Burslem, Staffs, 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 our invention has reference to potter's sifting-machines, n more especially

page_text: through connecting rods g, levers i and shaft by manual or other motive power
the blocks e are caused to slide or reciprocate to and fro upon the guides d. It
will be understood that two or more shorter brackets; but similar in shape to those
shewn may be used on one or both sides of such sifting-boxes if preferred instead
of a single bracket as shewn, the guide-blocks e may be separate, or connected as
shewn by a metallic web 7, and the inner end of the connecting-rods g may be made
to fit on or around the outer end 9.of the metallic plates 7 nearest to the back end
of such sifting boxes.
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.
olaim is
The mounting of the trays of potter's sifting-boxes upon four or more metallic
bars or brackets fixed to the underside of such trays in suitable position, the outer
end of such hars projecting through slots on each side of such sifting-boxes, and
bearing upon metallic-slide-blocks supported by metallic slides and brackets fixed
to the external surface of each side of such sifting-boxes, reciprocating motion
being transmitted to such trays through shafts, levers and connecting-rods as herein
substantially described and set forth.
