page_text: LETTERS PATENT to Laurence Malone, of Dublin, in the County of Dublin,
Ireland, for the Invention of "AN IMPROVED. APPARATUS FOR MIXING TEA
AND OTHER GRANULAR SUBSTANCES."
Sealed the 8th August 1879, and dated the 12th February 1879.
PROVISIONAL SPECIFICATION left by the said Laurence Malone at the
Office of the Commissioners of Patents on the 12th February 1879.
LAURENCE MALONE, of Dublin, in the County of Dublin, Ireland.
APPARATUS FOR MIXING TEA AND OTHER GRANULAR SUBSTANCES."
"
AN IMPROVED
My said Invention has reference to an improved apparatus for the mixing of teas
and other granular substances in an easy and effectual manner.
For this purpose I construct a cylindrical chamber or vessel, the ends of which
are closed, and through the centres of these ends a spindle or axis is passed, to one
end of which a crank handle is attached.
This cylindrical chamber or vessel I mount and cause to rotate in bearings
secured to suitable framework, and around its interior I arrange a series of spiral
shaped shelves or floats in such a manner that when the apparatus is rotated the
tea or other substances to be mixed will be thrown partly from end to end as well
as from side to side of the cylinder, and thus considerable agitation produced, and
an effectual mixture obtained.
A suitable opening is arranged in the side of the cylinder for the purpose of
introducing and removing the substance to be mixed.

"AN IMPROVED
LAURENCE MALONE, of Dublin, in the County of Dublin, Ireland.
--APPARATUS FOR MIXING TEAS AND OTHER GRANULAR SUBSTANCES."
My said Invention has reference to the mixing of teas and other granular
substances in an easy and effectual-manner.
For this purpose I construct a cylindrical chamber or vessel, the ends of which
are closed, and through the centres of these ends a spindle or axis is passed, to one
end of which a crank handle or hand wheel is attached. This cylindrical-chamber
or vessel I mount and cause to rotate in bearings secured to suitable framework,
and around its interior I arrange a series of spiral shaped shelves or floats in such
a manner that when the apparatus is rotated the tea or other substance to be
mixed will be thrown partly from end to end as well as from side to side of the
cylinder, and thus considerable agitation is produced, and an effectual mixture
obtained.
A suitable opening is arranged in the side of the cylinder for the purpose of
introducing and removing the substance to be mixed.
My said Invention will be more readily understood on reference to the accom-
panying Sheet of Drawings, in which Fig. 1 represents an elevation and Fig. 2 an
end view of the apparatus herein before described. A represents the cylindrical
chamber or vessel, which is caused to rotate in the direction of the arrow by means.
of the train of wheels shown in Fig. 2, and is mounted in suitable bearings on the
framework G; the spiral shaped floats or shelves are shown by the dotted lines
marked ff. It will be evident that these floats or shelves will cause the tea or
other granular substance to be thrown in longitudinal, and transverse directions as
the apparatus is being revolved, and a complete mixture thereby obtained.
Having thus described the nature of the said Invention, and how the same may
be applied in practice, I would have it understood that what I consider new and
useful, and therefore claim as the Invention secured to me by the herein before in
part recited Letters-Patent is, the employment of an apparatus constructed and
operated for the purpose and in the manner specified.
In witness whereof, I, the said Laurence Malone, have hereunto this my final
Specification set my hand and seal, this Ninth day of August, in the year
of our Lord One thousand eight hundred and seventy-nine.
