"IMPROVEMENTS IN APPARATUS FOR PRODUCING TRANSPARENT BLOCK ICE"
My improvement consists in a method of agitating the water in the freezing
chambers during the process of freezing, by a paddle or paddles constructed of
wood or metal or partly wood and partly metal in each chamber the reciprocating
stroke of which is shortened as the paddles or agitators are raised upwards which
may be done automatically or otherwise and at the same time the agitators or
paddles are constructed to yield should the water get frozen at the ends of the
chambers so as to impede their stroke they are also constructed to collapse
laterally should the ice on the sides of the chambers touch them
These paddles are placed in a row or rows and suspended from a bar of metal or
partly metal and partly wood which stretches across the range of freezing chambers
from end to end of the tank in which they are placed the paddles to pass easily
through rectangular holes in the bar the upper ends of the paddles having projecting
bearings to rest on the said bar The openings in the bar are made wider on the
under side to allow the paddles to vibrate should they touch the ice at the end of
the chambers and they are brought to their first-position by springs which bear on
either side
As the whole of the paddles in the range have the same stroke and simultaneous
action should the water in any of the chambers get frozen towards the bottom
before the lifting apparatus has freed the paddles the ice coming in contact with
their lower ends will raise the paddles through the bar and they will be held in
their then position by the springs The bar from which the paddles are suspended
passes at the ends through guide pieces which are connected together so as to form

carry a top frame to steady the guide frame the corners of which are formed to fit
the pillars they have springs or other clastic medium or rollers to bear on themi
The bar from which the paddles are suspended is formed to slide horizontally in
the guide pieces and whether the bar is constructed of all metal or not the ends
that slide in the guides are preferably metal the extremities being so and forming
round bearings embraced by metal bushes which slide in longitudinal openings in
levers which communicate the reciprocating motion to the bar imparted to them
by the motive power and as the guide frame is raised the stroke of the paddles is
shortened as the bar moves towards the centre of motion
These levers are fixed on the ends of a horizontal shaft the bearings of which
rest on pillow blocks on the top frame the vibrating motion is given to them by an
eccentric disc or discs crank or cranks or other means connected with the motive
power When thrown out of gear and the paddles raised clear of the freezing
chambers the levers connected with the agitator bar along with the bar may be
moved to one side thereby placing the paddles clear of the freezing chambers to
allow of the removal of the said chambers with the ice blocks in them or the ice
blocks from fixed freezing chambers and which may be then carried off on a trolly
or rails at the sides of the tank or other-wise The lifting of the agitator frame
may be by means of chains or ropes over pullies to a barrel with gearing connected
with the motive power constructed to revolve at a speed so regulated that by the.
time required to freeze the blocks completely the lower extremities of the paddles
shall be raised from the bottom of the chambers to the top This barrel to be
made so that it can be thrown out of gear and the agitator frame raised or lowered
by hand.
Hydraulic power may be used in place of a revolving barrel by having a ram
placed under each of the four corners of the frame
To cover the openings required for the action of the paddles in the cover of the
tank if necessary bands of some flexible substance may be made to cover each
opening with an aperture or apertures to admit the paddles freely througli
them The ends of the bands to hang over the sides of the tank and loaded
sufficiently to keep them from doubling up when moved along by the stroke of the
paddles
There may be rollers on the top edge of the tank for the bands to pass over
the loaded ends causing the bands to lie flat on the tank cover In place of bands
sliding covers of wood or metal may be used.

"IMPROVEMENTS IN APPARATUS FOR PRODUCING TRANSPARENT BLOCK ICE"
My improvements consist in certain arrangements of apparatus for agitating the
water in the freezing chambers during the process of freezing by means of a
paddle or paddles constructed of wood or metal or partly of wood and partly of
metal placed in each chamber; the reciprocating stroke of such paddles or
agitators being shortened as they are raised upwards. The raising upwards of
the said paddles or agitators may be effected automatically or otherwise. They
are constructed to yield should the water get frozen at the ends of the chambers
so as to impede their stroke and they are also constructed to collapse laterally
should the ice on the sides of the chambers touch them
In the drawings hereto annexed Fig 1 is an elevation partly in section showing
an apparatus constructed in accordance with my invention applied to a range of
freezing chambers. Fig 2 a plan of same and Figs 3, 34 and 3B enlarged views of
the collapsing paddles or agitators. These paddles c are placed in a row or rows
and suspended from a bar s of metal, or partly of metal and partly of wood which
stretches across the range of freezing chambers bb from end to end of the tank a
in which they are placed. The paddles c are adapted to pass easily through
rectangular holes in the bar s the upper ends of the said paddles being furnished
with projecting arms or bearings adapted to rest on the said bar & as shown in
Figs 3, 34 and 3B.
.
The openings in the bar s are made wider on the under side than on the upper
(see Fig 3) to allow the paddles c to vibrate should they touch the ice at the end
of the chambers and they are returned to their first position by springs q which
bear on either side. As the whole of the paddles in the range have the same
stroke and simultaneous action should the water in any of the chambers get frozen
towards the bottom before the lifting apparatus has freed the paddles, the ice
coming in contact with their lower ends will raise the said paddles through the
bars and they will be held in their then position by the springs q. In order
to enable the paddles or agitators c to collapse laterally when the ice on the
sides of the chambers touches them, they are each constructed of two or more.
separate parts or blades hinged together at or near their upper ends and
arranged to close together or to collapse laterally by the pressure of the ice
against them as it grows on the sides of the freezing chambers Fig 3 shows
the said parts or blades expanded and Fig 34 shows them closed together or
collapsed, Fig 3B being a view of the paddle seen edgewise. The bar 8 from
which the paddles c are suspended passes at its ends through guide pieces d
which are connected together by side pieces so as to form a rectangular frame
the four corners of which embrace four upright columns or pillars e which carry a'
top frame f. To steady the guide frame the corners, which are formed to fit the
pillars are furnished with springs or other elastic media, or rollers to bear
against the said collars or pillars The bar s from which the paddles care
suspended is adapted to slide horizontally in the guide pieces d and whether
the said bar is constructed wholly of metal or not the ends which slide in-
the guides are preferably of metal forming round bearings which are embraced
by metallic brushes sliding in longitudinal openings in the levers g which.
communicate the reciprocating motion to the bar s through the lever / actuated
by any suitable motive power. As. the guide frame d is raised the stroke of
"

page_text: the paddies is shortened in proportion as the bar s is moved towards the
centre of motion of the levers g, h,. These levers are fixed in the ends of a
horizontal shaft the bearings of which rest in pitlow blocks on the top frame.
The vibrating motion is imparted to them by eccentric discs, cranks, or other
suitable means connected with the motive power.
When thrown out of gear, and the frame & with the bars and paddles c
are raised so that the latter stand above the freezing chambers b, the levers y
and the bar & may be moved to one side, as shown in dotted lines in fig 1,
whereby the paddles are placed clear of the freezing chambers b to allow of
the removal of the said chambers with the ice blocks in them or of the ice
blocks from fixed freezing chambers (when such are employed) these blocks
may then be carried away on a trolly running on rails at the sides of the
tank or otherwise. The dotted lines 2, 2, show how the ice forms in the
chambers and necessitates the raising of the paddles c and the diminution
of their stroke as the freezing operation progresses. The lifting of the agitator
frame d may be effected by chains or ropes passing over pullies to a barrel j
connected with the motive power by gearing so constructed as to cause the
barrel to revolve at a speed dependent upon the time required to freeze the
blocks completely by which time the lower ends of the paddles are to be raised
from the bottom of the chambers to the top.
This barrel is by preference so arranged that it can be disengaged from the
motive power and the agitator frame & then raised or lowered by hand. The
weight of the frame d may be balanced by a counterbalance weight /.
Hydraulic power may be used instead of a revolving barrel for raising the
agitator frame. Fig 4 is a side elevation partly in section showing two sets of the
apparatus arranged together and furnished with hydraulic presses for raising the
agitator frame Fig 5 is a plan and Fig 6 a front elevation of same. Letters of
reference in Figs 4, 5, and 6 which are similar to those in figs 1 and 2 indicate
similar parts in all those figures. The paddles of both these sets of apparatus may
be operated by the same crank plates r, r, by means of the connecting rods t t.
The hydraulic rams u u are placed under each of the four corners of the frames d.
vis a pipe supplying water under constant pressure w, w, are branch pipes leading
from the pipe to the hydraulic cylinders x x are stop cocks to regulate the
water supply to the hydraulic cylinders for lifting the frame d when the stop
cocks y are shut. y, y, are stop cocks for the discharge of water from the hydraulic
cylinders to allow the frame to descend when the cocks x x are shut.
Figure 7 is an elevation partly in section of two sets of apparatus showing
arrangements for applying the motive power to the lower ends of the levers g.
o is a connecting rod which receives a reciprocating movement from a crank or
otherwise and p p are sliding end pieces for disconnecting the rod o from the
levers when the latter are turned up to clear the freezing chambers. The other
parts in Fig 7 are indicated by lettering similar to that employed in Figs 1. 2. 4.
5. & 6
In order to cover, when necessary, the openings in the cover of the tank required
for the action of the paddles, bands of some flexible substance with an aperture or
apertures therein to admit the paddles freely through them may be made to cover
each opening. The ends of the said bands may hang over the sides of the tank
and be loaded or weighted sufficiently to keep them from doubling up when moved,
along by the stroke of the paddles.
Rollers may be placed on the top edge of the tanks for the bands to pass over
the loaded ends causing the bands to be flat on the tank cover. In place of bands
sliding covers of wood or metal may be employed.
Having now described the nature of the said invention and the manner in
which the same is to or may be carried into effect I would have it understood that
I make no claim to agitating water in the freezing chambers of ice making
apparatus as that method of producing transparent ice is already well known, but
what I do claim is,

page_text: First. The slotted oscillating levers g, the horizontal guides & and the paddle or
agitator bar s so arranged adapted and combined that as the bar s carrying the
paddles or agitators c is raised vertically by the motion of the guides d, as the ico
forms in the freezing chambers, the horizontal travel or stroke of the said bar s
and the paddles or agitators carried thereby is proportionately reduced as herein-
before described and illustrated in Figures 1, 2, 4, 5, 6 and 7 of the drawings
hereto annexed and for the purposes set forth.
Second The arrangements of apparatus for raising the paddles or agitators as
the ice forms in the freezing chamber as herein before described and illustrated in
Figures 1, 2, 4, 5 and 6 of the drawings hereto annexed and for the purpose set
forth.
Third The construction of the paddles or agitators in two or more separate parts
or blades, hinged together at or near their upper ends, and arranged to close
together or to collapse laterally by the pressure of the ice against them as it grows
on the sides of the freezing chambers, as herein before described and illustrated in
Figures 3. 3 and 3B of the drawings hereto annexed.
Fourth The arrangements for suspending the paddles or agitators freely in slots
formed in the carrying bars, such slots being wider at the bottom than at the top,
and the said paddles or agitators being held flexibly by springs which allow them
to yield when they come in contact with the ice at the ends of the freezing
chambers, and to be pushed up and held in the said slots as the ice forms at the
bottoms of the said chambers as hereinbefore described and illustrated in Figure 3
of the drawings hereto annexed, and for the purposes specified.
In witness whereof I the said Charles Denoon Young have hereunto set my
hand and scal this twenty fifth day of September in the year of our
Lord One thousand eight hundred and eighty two.
