PROVISIONAL SPECIFICATION.
Improvements in
in or connected with Webs, Trays, Flaps, or
Carriers for Carrying Tea Leaf or other Substances in Drying
Machines.
1, WILLIAM JACKSON, of Thorn Grove, Mannofield, Aberdeen, North Britain,
Engineer, do hereby declare the nature of my invention to be as follows:-
My invention relates to webs, trays, flaps, or carriers, for carrying tea leaf
or other substances in drying machines. Such webs, trays, flaps, or carriers,
whether made as endless travelling webs, or as flaps, or louvres, to tilt over to
discharge the leaf, or other substance, to the support below, have hitherto been
made of perforated metal, but it is not possible to make the perforations therein
small enough to prevent small particles such as dust, or fine tea, or the like, from
falling therethrough. According to my invention I cover one side, or both sides,
of such perforated webs, trays, flaps, or carriers, with wire gauze of fine mesh,
which is counected to the said perforated webs, trays, flaps, or carriers, in any
convenient, or suitable, way, such for example as by clips, rivets, or wire, so that
it forms practically part of the perforated webs, trays, flaps, or carriers, and
prevents small particles such as dust, or fine tea, or the like, from passing through
the perforations, whilst the heated air can pass therethrough efficiently the
perforated webs, trays, flaps, or carriers, acting as supports for the wire cloth and
preventing it from buckling or becoming distorted.

Improvements in or connected with Webs, Trays, Flaps, or
Carriers for Carrying Tea Leaf or other Substances in Drying
Machines.
1, WILLIAM JACKSON, of Thorn Grove, Manuofield, Aberdeen, North Britain,
Engineer, do hereby declare the nature of my invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention relates to webs, trays, flaps, or carriers, for carrying tea leaf or
other substances in drying machines. Such webs, trays, flaps, or carriers, whether
made as endless travelling webs, or as flaps, or louvres, to tilt over to discharge
the leaf or other substances, to the support below, have hitherto been made of
perforated metal, but it is not possible to make the perforations therein small
enough to prevent small particles such as dust, or fine tea, or the like, from falling
therethrough. According to my invention I cover one side, or both sides, of such
perforated webs, trays, flaps, or carriers with wire gauze of fine mesh, which is
connected to the said perforated webs, trays, flaps, or carriers, in any convenient,
or suitable, way, such for example as by clips, rivets, or wire, so that it forms

page_text: practically part of the perforated webs, trays, flaps, or carriers, and prevents small
particles such as dust, or fine tea, or the like, from passing through the perforations,
whilst the heated air can pass therethrough efficiently, the perforated webs, trays,
flaps, or carriers, acting as supports for the wire cloth and preventing it from
buckling, or becoming distorted:
In the accompanying drawings I have shewn portions of webs, trays, flaps, or
carriers, according to my invention from which its general application will be
readily understood.
Each figure shews a plan and an edge view. Figures 1, 4 and 5 shewing edge
views at right angles to each other.
Figure 1 shews the application to a perforated metal tray to be used in an
endless web machine the said tray being covered with wire gauze which is shewn
as being secured to the perforated metal by means of clips A.
Figure 2 shews the same kind of tray with the wire gauze secured to the
perforated metal by means of rivets B.
Figure 3 shews the same kind of tray with the wire gauze secured by means of
wire C.
Figure 4 shews a tray to be used in the same kind of machine with the perforated
metal covered on both sides with wire gauze secured by means of clips A, but it
may be secured by rivetting or sewing as shewn in Figures 2 and 3.
Figure 5 shews the application to a tray flap or louvre. to be used in a drying.
machine where the trays, flaps, or louvres open and shut like. the laths of a
Venetian blind so that the material being dried, drops therefrom onto the surface
below. The wire gauze is shewn as being attached to the perforated metal by
means of clips A but it can be secured by rivets or by sewing as shewn in
Figures 2 and 3 if preferred.
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 :-
In or for drying machines for drying tea leaf or other substances, perforated
metal webs, trays, flaps, or carriers, covered on one side or on both sides with wire
gauze substantially as and for the purposes herein before described and illustrated
by the examples shewn in the accompanying drawings.
