Year: 1880

page_text: LETTERS PATENT to Thomas Matthews, Civil Engineer, of Riversbrooke, Wood
Green, in the County of Middlesex, for an Invention of "IMPROVEMENTS IN
MACHINERY FOR WASHING, CLEANSING, AND MIXING CEMENT, LIME, SAND,
GRAVEL, AND OTHER MATERIALS USED IN MAKING MORTAR AND CONCRETE,
AND FOR OTHER SIMILAR OR SUCH LIKE PURPOSES."
PROVISIONAL SPECIFICATION left by the said Thomas Matthews at the
Office of the Commissioners of Patents on the 14th April 1880.
THOMAS MATTHEWS, Civil Engineer, of Riversbrooke, Wood Green, in the
County of Middlesex. "IMPROVEMENTS IN MACHINERY FOR WASHING, CLEANSING,
AND MIXING CEMENT, LIME, SAND, GRAVEL, AND OTHER MATERIALS USED IN
MAKING MORTAR AND CONCRETE, AND FOR OTHER SIMILAR OR SUCH LIKE
PURPOSES."
My Invention consists of a machine or apparatus for the preparation of materials
such as sand, gravel, broken granite, slag, bricks, or stones of any kind by
thoroughly cleansing them from all natural or other impurities with which they
may be associated. Also for mixing these said or other similar materials with
lime, cement, plaster of Paris, or other binding agents for the purpose of making
mortar, concrete, or other compound used for building, paving, or such like
purposes. The machine or apparatus may also be used for cleansing crushed ores
and separating the metal therefrom.
The said machine consists of a wooden, iron, or stone trough of any desired
length or width having divisions in its under side or bottom, plain or segmental in
section. In each of such divisions pendulous arms connected together by the
necessary framework oscillate to and fro. At the extremity of each arm a paddle,
rake, shovel, scoop, or harrow is attached by a hinge or fixed arrangement, so that.
when the frame to which the arms are fastened oscillates each arm traverses the
space of the segmental or plain division in which it is placed, and its traversing,
motion rakes or agitates the material which is gradually passed on by the arms in
succession until the process of washing, cleansing, and mixing is finished.

page_text: The water for cleansing purposes may be introduced at any point in the length
or breadth of the trough, and in such quantities as may be desired.
For mixing purposes the machine may be used either wet or dry, according to
the purpose for which the materials are required.
Motion is imparted to the machine by an eccentric or crank arrangement and 5
may be driven by manual, horse, steam, or other motive power.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Matthews in the Great Seal Patent Office on the 14th
October 1880.
THOMAS MATTHEWS, Civil Engineer, formerly of Riversbrooke, Woodgreen, in
the County of Middlesex, but now of 10, Caistor Villas, Manor Road, Stoke
Newington. "IMPROVEMENTS IN MACHINERY FOR WASHING, CLEANSING, AND
MIXING CEMENT, LIME, SAND, GRAVEL, AND OTHER MATERIALS USED IN MAKING
MORTAR AND CEMENT, AND FOR OTHER SIMILAR OR SUCH LIKE PURPOSES."
My Invention consists of a machine or apparatus for the preparation of materials
such as sand, gravel, broken granite, slag, bricks, or stones of any kind by
thoroughly cleansing them from all natural and other impurities with which they
may be associated. Also for mixing these said or other similar materials with
lime, cement, plaster of Paris, or other binding agents for the purpose of making
mortar, concrete, or other compound used for building, paving, or such like
purposes. The machine or apparatus may also be used for cleansing crushed ores
and separating the metal therefrom.
The said machine consists of a wooden, iron, or stone trough of any desired
length or width, having divisions on its under side or bottom, plain or segmental
in section. In each of such divisions pendulous arms connected together by
the necessary framework oscillate to and fro. At the extremity of each arm a
paddle, rake, shovel, scoop, or harrow is attached by a hinge or fixed arrangement,
so that when the frame to which the arms are fastened oscillate each arm traverses
the space of the segmental or plain division in which it is placed, and its traversing
motion rakes or agitates the material which is gradually pressed on by the arius
in succession until the process of washing, cleansing, or mixing is finished.
The water for cleansing purposes may be introduced at any points in the length
or breadth of the trough and in such quantities as may bo desired. For mixing
purposes the machine may be used either wet or dry according to the purpose for
which the materials are required. Motion is imparted to the machine by an
eccentric or crank arrangement and may be driven by manual, horse, steam, or
other power.
And for more fully describing the nature of my said Invention I say that it
consists of a machine or apparatus for preparing materials, such as sand, gravel,
broken granite, slag, brick, or stones of any kind, by cleansing them from all natural
or other impurities with which they may be naturally or artificially mixed or

Figure 1 represents a longitudinal section of a different description from that
delineated on Drawing No. 1, and for which another arrangement is provided for
suspending the framework and its attached arms or paddles. The trough is of the
same description as that already described, and made in the same manner, its anglo
of inclination also being capable of adjustment at pleasure. The framework is
suspended by iron pendulums or connecting rods A, A, and connected by overhead
standard or support, the motion being applied by crank or eccentric at any part of
the suspended part of the machine, or as shown at letter F. B, B, represent
the bottom of the trough; C, C, C, its supports or standards; D, D, the movable
frame; and E, E, the paddles or scrapers, which may be tipped or shod with movable
steel points to permit of their separation or renewal when worn.
Having thus described the nature of my said Invention, and in what manner the
same is to be performed, I declare that what I claim is,—
The application of paddles, scoops, or scrapers for cleansing gravel and other
materials, which when cleansed are passed out of the machine by the action of the
framework to which the paddles, &c., are attached, as above described.
In witness whereof, I, the said Thomas Matthews, have hereunto set my hand
and seal, this Fourteenth day of October, in the year of our Lord One.
