GEORGE LAWRENCE of St. Mary Axo, in the County of Middlesex, IMPROVE-
MENTS IN REFRIGERATORS, CONDENSERS, CALORIFERS AND VAPORISERS,
The improvements relate to the following novel features which may be used
separately or in combinations of two or more, and they consist in the building up
of pieces or segments of corrugated metal, or other plates or surfaces in pairs or
series of pairs vetically, horizontally, at an angle, or in curved form, equidistant
from each other or otherwise and forming refrigerators, condensors or calorifers-
Also in the addition of hinged or detachable ends, or pieces, to serve as inlet or
outlet or both, or to close up, and act as stay and distance pieces to the said cor-
rugated plates-Also in the construction and use of external stays or supports
fitting into and holding the corrugations, or embracing tubes, or troughs, and made
to form fixed or detachable or hinged sides, tops, bottoms, and ends or some of them,
secured in place by bolts or otherwise. Also in the use of fixed or movable ripple
plate or plates serving as stays or otherwise. Also of apparatus formed with a
centre chamber and side troughs, or side chambers, and centre trough, or of a series
of such-Also in placing the corrugated surfaces not equidistant one from the
other in all their areas, but in places at an angle to each other or curved-Also in
the use of a corrugated or ribbed false bottom or strainer made in one or more
pieces to be used in combination with the said improvements or some of them, or
as a strainer for general purposes-Lastly in the construction of apparatus for
vaporizing fluids disinfected or otherwise composed of one or more fixed or movable
screens with or without fringes or meshes attached, made to travel, or stationary,
supplied with fluids; forcing or sucking air over or through such screens, for the
purpose of killing germs, or disinfecting or cooling or warming purposes. The
improvements may be performed by making the corrugated surfaces or plates of
metal, glass, carthenware or other convenient material; the ends may be of cast
or wrought metal, or of the same material as the plates-likewise the stays which
are made fixed, or detachable, and to such stays may be attached the sides, tops,
bottoms and ends, or these latter may be made in or of separate pieces; the ripple
plates or plate made of any convenient material is placed externally in the channels,
and internally in the tubes or troughs, they be either fixtures or detachable―

page_text: The chamber and trough apparatus may be made all in a piece of metal or other
convenient material or in separato pieces fixed or held together and supported on
a convenient bed plate, or suspended-In some cases the corrugated plates instead
of being placed equidistant from cach other, each plate or series may be wholly or
in parts inclined at an angle to the other plate or series or arranged in a curved
form The corrugated or ribbed strainer can be made of the same material as the
corrugated plates and for convenience of cleansing and removal is made to fit or
rest on or in recesses or otherwise. The vaporisers are made of metal or other
convenient material with fringes, or in some cases may consist of an endless canvas
or perforated metal sheet passing over rollers, and dipping into or supplied with
suitable fluids, blast fans or bellows are employed to drive or suck the air through
such fringes or sheets, or to send a current of air over them.
