IMPROVEMENTS IN APPARATUS FOR MAKING ARTIFICIAL ICE
Year: 1880

page_text: LETTERS PATENT to Charles Edward Young, of 12, Osborne Terrace, Clapham
Road, in the County of Surrey, Engineer, for an Invention of "IMPROVEMENTS
IN APPARATUS FOR MAKING ARTIFICIAL ICE."
PROVISIONAL SPECIFICATION left by the said Charles Edward Young at
the Office of the Commissioners of Patents on the 28th February 1880.
CHARLES EDWARD YOUNG, of 12, Osborne Terrace, Clapham Road, in the
County of Surrey, Engineer. "IMPROVEMENTS IN APPARATUS FOR MAKING
ARTIFICIAL ICE."
My Invention consists in the application of a lever with a fixed pivot having
an oscillating up & down movement, thus by this ascending and descending
movement obliging the water to rise and fall like a wave in the cell or any
other receptacle.
To attain this object I place in the bottom part of each tank or receptacle an
apparatus working on a fixed pivot constructed of a board or flap of metal, wood,
hardened india rubber, or any other appropriate material adapted, by the com-
bination of pivoted levers, to produce the rising and falling movement of the
water like a wave, maintaining in each of the cells a continual movement of
revolution in the water, by which means I obtain artificial ice limped and
transparent.
By my new process the freezing can be continued as well as the movement of
the water until each block is entirely solid without necessitating the stoppage of
the rising and falling movement of the water to introduce the cords, or for any
other purpose, as is necessary in the systems at present in use, which_stoppage
causes the opacity of the ice in the centre of the block, which opacity I cause to
disappear by my new arrangement of pivoted board or flap working before, during,
and after the complete congelation of the ice, that is to say, my apparatus is entirely
independent of the cells.
The pivotted shaft on which is fixed each oscillating board rests at one side in a
bracket, at the other it passes through a stuffing box, so that the oscillation
backwards & forwards acts regularly without shock, being actuated by wheel
gearing, eccentrics, cranks, or any other of the well known mechanical movements.
My Invention also includes au apparatus which carries out the principle of the
rising and falling movement of the water without a pivot fixed at the centre, the
Oscillating movement being replaced by a perpendicular piece of parallel cross
section, and of a horizontal section the same as the tank.

the said Charles Edward Young in the Great Seal Patent Office on the 27th
August 1880.
CHARLES EDWARD YOUNG, of 12, Osborne Terrace, Clapham Road, in the
County of Surrey, Engineer. "IMPROVEMENTS IN APPARATUS FOR MAKING
ARTIFICIAL ICE."
My Invention consists in applying to ordinary freezing tanks the apparatus
herein after described, or one of them, in order to cause the necessary motion of the
water, whereby limpid and transparent ice can be obtained.
Below the brine cells I arrange sufficient space for a plane constructed of wood
or other suitable material to oscillate or vibrate upon a central transverse axle or
fixed pivot, thus imparting to the water a wave motion, the said axle or pivot
being supported by a suitable socket or plummer block at one end, and the other
end of such axle or pivot passing through the side of the tank with a suitable
bearing, having a stuffing box and a crank fitted thereto for imparting the necessary
motion thereto.
By means of my Invention the freezing can be continued as well as the
movement of the water until each block is entirely solid without necessitating
the stoppage of the motion to introduce the cords, or for any other purpose, such
stoppages causing opacity in the middle of the block of ice, which opacity is
prevented by the continuous and uninterrupted motion imparted to the water by
my improvements.
And in order that my said Invention may be more clearly understood, reference
is made to the accompanying Drawings, wherein Figure 1 is a plan of a freezing
tank with my improvements; Figure 2 is a longitudinal sectional elevation on the
line a, b, of Figure 1; and Figure 3 is a transverse sectional elevation on the line
c, d, of Figure 1.
Similar letters indicate similar parts in all the Figures. e is the oscillating plane
fitted to and supported by the axle or pivot f; g is the insido socket or bearing;
is the outer bearing with a stuffing box; i is the crank which receives a vibratory
motion through the connecting rod ; 1, 2, are the metallic cells containing the
refrigerating fluid; and m, m, is the outer casing of the tank. The arc of vibration
of the plane e can be increased or decreased at pleasure by means of the crank i,
but is limited by the space available beneath the cells.
Having now described the nature and object of my said Invention, I would have
it understood that instead of imparting an oscillating pivotted motion to the said
plane, in the manner herein before described, I inny in some cases actuate the plane
in a vertical up and down movement without a pivot fixed at the centre, by means
of suitable levers or their equivalents fitted to the upper part of the tank, in which
case every part of the plane rises and falls simultaneously; and I declare that
what I claim and desire to be secured to me by the herein before in part recited
Letters Patent is,―
The combination and arrangement of apparatus for obtaining a continuous and
uninterrupted motion of the water in order to produce limpid and transparent ice,
substantially as herein before described and shewn on the Drawings, or any mere
modification thereof.
In witness whereof, I, the said Charles Edward Young, have hereunto set
my hand and seal, this Twenty first day of August, in the year of our
Lord Oue thousand eight hundred and eighty.
CHARLES ED. YOUNG. (LS.)
