IMPROVEMENTS IN TEA ROLLING MACHINERY to be as follows:-

page_text: We JAMES CRICHTON KINMOND of Sunnycroft, Leamington, Warwickshire,
Engineer, and JOHN RICHARDSON of the firm "Robey & Co" of Lincoln in the
County of Lincoln, Engineers, do hereby declare the nature of our said invention
for "IMPROVEMENTS IN TEA ROLLING MACHINERY to be as follows:-
"
This invention relates to improvements in machines for rolling tea leaf and
consists in making such machines more simple of construction, easier to drive, and
more effective in their action.
In previous machines various designs bave been adopted in order to get a circular
rolling motion of the tea leaf between the upper and lower tables and it has been
found that when the upper table only was moved, that the tea was only partially
rolled owing to the part resting on lower table, remaining stationary or nearly so,
and when both tables were given a circular rolling motion great complexity was
introduced with the mechanism and much power was wasted in driving.
In the machine which is the subject of this invention all these objections are
overcome. The machine consists of one circular hopper lined with wood and
receiving its tea leaf from an opening near one end, within this hopper or casing
the upper table is free to move vertically and can be raised by a screw.
This hopper and table receive their motion from a single crank which gives a
circular motion to the inner point, while the point at the opposite end slides in
a straight line, the resulting motion of upper table being an oval which is elongated
as it nears the outer end and approximates nearly to a circle at the part nearest
the inner end.
In order to bring every part of the leaf under the action of the greatest rolling
surface the under table is caused to revolve upon its centres in a contrary direction
to the upper table, were this to take place continually this object would be accom-
plished, but in order not only to subject the whole to equal rolling but also to get
approximately an equal motion at all points, the lower table is caused to rest while
the hopper is taking its motion in the same direction as table, and to move while
the hopper is going contrary to table thus increase the rolling motion at this point,
when most needed the resultant curve described being nearly a circle at all points.

page_text: In order to effect this object an eccentric is keyed on to the vertical driving shaft
a rod from eccentric works a lever and by means of a pawl and ratchet wheel the
required motion at the required time is given to lower table.
In order to reduce the wear of the lower table to a minimum the surface may be
made of hard wood in suitably shaped blocks set up endwise of the grain.
The main features of this invention are:-
The combination of the upper hopper and table worked by one crank with a
lower table to which a slow revolving or hitching motion is given; and the applica-
tion of wood set endwise of the grain to form a hard wearing surface.

We JAMES CRICHTON KINMOND of Sunnycroft, Leamington, Warwickshire,
Engineer and JOHN RICHARDSON of the firm "Robey & Co of Lincoln, in the
county of Lincoln, Engineers, do hereby declare the nature of our said invention
for "IMPROVEMENTS IN TEA ROLLING MACHINERY" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in machines for rolling Tea leaf and
consists in making such machines more simple of construction, easier to drive, and
more effective in their action.
In previous machines various designs have been adopted in order to get a circular
rolling motion of the Tea leaf between the upper and lower tables and it has been
found that when the upper table only was moved, that the tea was only partially
rolled owing to the part resting on lower table remaining stationary or nearly so,
and when both tables were given a circular rolling motion great complexity was
introduced with the mechanism and much power was wasted in driving.
In the machine which is the subject of this invention all these objections are
obviated.
The machine as shown in the annexed drawings Figures 1 and 2 consist of one
circular hopper C lined with wood and receiving its tea leaf from the opening at
D, D, within this hopper or casing the upper table A is free to move vertically and
can be raised by a screw E.
This hopper and table receive their motion from a single crank F which gives a
circular motion to that point, while the point G slides in a straight line the result-
ing motion of the upper table being an oval which is elongated as it nears the
outer end G and approximates nearly to a circle at the part nearest F.
In order to bring every part of the leaf under the action of the greatest rolling
surface the under table B is caused to revolve upon its centres in a contrary direc-
tion to the upper table, were this to take place continually this object would be
accomplished but in order not only to subject the whole to equal rolling but also to
get approximately an equal motion at all points, the lower table B. is caused to rest
while the hopper C is taking its motion in the same direction as table A and to
move while the hopper is going contrary to table B thus increasing the rolling
motion at this point when most needed, the resultant curve described being nearly
a circle at all points.
In order to effect this object an eccentric H is keyed on to the vertical driving
shaft I a rod from eccentric works the lever J Figure 2 and by means of a pawl K
and ratchet wheel L the required motion at the required time is given to lower
table.
In order to reduce the wear of the lower table to a minimum the surface may be
made of hard wood in suitably shaned blocks set un end wise of the arain

page_text: 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
1. The combination of the upper hopper and table worked by one crank with a
lower table to which a slow revolving or hitching motion is given.
2. The application of wood set endwise of the grain to form a hard wearing
surface of the lower table.
