AN IMPROVED APPARATUS FOR MIXING TRA OR OTHER SUBSTANCES
Year: 1885

page_text: 1, EDMUND BURKE, of 17 and 18 High Street, Dublin, Tea Merchant, do hereby
declare the nature of the said invention for AN IMPROVED APPARATUS FOR MIXING
TRA OR OTHER SUBSTANCES to be as follows:-
The object of my invention is to produce an apparatus for mixing tea or other
substances in a convenient, simple, and effectual manner, and without injury to
the leaf.
For this purpose I form a chamber composed of a suitable number of sides, and
provided with two ends, capable of rotating on a spindle or axle in the manner
presently described. Within this chamber I arrange a number of shelves longi-
tudinally, their ends being fixed to the inner surface of the ends of the chamber,
and so placed that spaces are provided between the edges of each shelf and the
centre as well as the circumference of the chamber. The spindle or axle on which
this chamber rotates is inserted not in centre of the ends, but through suitable
points in said ends, so as to impart an eccentric motion to the chamber. By this
arrangement it is obvious that two motions are imparted to the tea-or other
substance placed within the chamber, viz a rotary and a lateral one.
The action of my invention may be described thus: The tea, or other substance,
is introduced in the usual manner through a suitable opening in the side, and upon
the axle or spindle being rotated it is distributed over the above described shelves,
falling over the longitudinal shelves of same, while at the same time it is thrown
from end to end, a complete mixture being thereby effected.
Dated this 9th day of November 1885.

page_text: I EDMUND BURKE of 17 and 18 High Street Dublin, Tea Merchant, do hereby
declare the nature of my invention for "AN IMPROVED APPARATUS FOR MIXING
TEA OR OTHER SUBSTANCES" and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
The object of my invention is to produce an apparatus for mixing tea or other
substances in a convenient, simple and effectual manner and without injury to
the leaf.
For this purpose I form a chamber composed of a suitable number of sides and
provided with two ends capable of rotating on a spindle or axle in the manner
presently described.
Within this chamber I arrange a number of shelves longitudinally, their ends
being fixed to the inner surface of the ends of the chamber and so placed that
spaces are provided between the longitudinal edges of each shelf and the centre, as
well as the circumference, of the chamber. The spindle or axle on which this
chamber rotates is inserted not in the centre of the ends but through suitable
points so as to impart an eccentric as well as rotatory motion to the chamber.
By this arrangement it is obvious two motions are imparted to the tea or other
substance placed within the chamber viz-a rotatory and a lateral motion.
The action of my invention may be described thus:-The tea or other substance
is introduced in the usual manner through a suitable opening in the side and upon
the axle or spindle being rotated it is distributed over the above described shelves

understood and carried
In order that my said invention may be more readily
into practice I will describe the accompanying Drawings.
Fig. 1 is an end elevation. Fig. 2 is a side elevation. Fig. 3 is a section on
line Fig, I shewing the longitudinal shelves, b, b, and Figs. 4 and 5 show cross
section and plan of the shelves arranged in the chamber.
In Figs. I and 2. A. A. represents the framework of the machine which may be
of such construction as may be found suitable for the purpose in view; B, is the
chamber which is operated by the lever handle C, through the pinion D. and spar
wheel d. The arrangement of the shelves in the interior of the chamber is shown
in the cross section Fig. 3. In the construction of the shelves a web or ledge f
(Figs. 4 and 5) may with advantage be introduced for the purpose of assisting in
throwing the tea or other substance from end to end during the rotation of the
chamber. The edges of the shelves are rounded off as shown so as to obviate the
tendency of breaking the leaf.
Underneath the chamber is arranged a hopper D¹, into which the tea or other
substance is discharged when the operation of mixing is complete and at the neck
of this hopper a number of suitable openings 9, 9, provided with slide shutters are
introduced for the purpose of facilitating the filling of chests, or other vessels as
the case may be.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I desire to state that
I am aware that Letters Patent have been granted to R. H. Broom of Portobello
Road, Notting Hill London for "An improved Tea blender," dated 24th September
1885 No. 11,388 and I do not claim a box or container with a suitable number
of cross bars inside, as described & claimed in said Letters-Patent, but I declare
that what I claim is
First. In an apparatus for mixing tea, or other substance, the construction and
arrangement of a chamber containing a suitable number of internal shelves
as herein described and shewn in the accompanying Drawings.
Second. In an apparatus for mixing tea or other substance the combination
formed by the chamber B with the internal shelves, b, b, so arranged and operating,
substantially as herein described and set forth in the accompanying Drawings.
