IMPROVEMENTS IN APPARATUS FOR MANUFACTURING ICES, ICE CREAMS, AND OTHER ANALOGOUS PURPOSES
Year: 1880

page_text: LETTERS PATENT to Charles France, of No. 28, Rosoman Street, Clerkenwell,
in the County of Middlesex, Fitter, for an Invention of "IMPROVEMENTS IN
APPARATUS FOR MANUFACTURING ICES, ICE CREAMS, AND OTHER ANALOGOUS
PURPOSES."
PROVISIONAL SPECIFICATION left by the said Charles France at the
Office of the Commissioners of Patents on the 18th August 1880.
CHARLES FRANCE, of No. 28, Rosoman Street, Clerkenwell, in the County of
Middlesex, Fitter. "IMPROVEMENTS IN APPARATUS FOR MANUFACTURING ICES,
ICE CREAMS, AND OTHER ANALOGOUS PURPOSES."
The object of my said improvements are to promote cleanliness and afford
increased facilities in revolving the freezers of ice making apparatus. The former
I secure by making the revolving freezers of glass, earthenware, or porcelain,
porous or otherwise, and the latter by the arrangements for mounting herein after
mentioned.
In carrying out my said Invention I fit into a suitable table or frame one or
more (by preference four) ice tubes.
When four are used I arrange these tubes two at each end of the table, and
mount upon the table two flywheels upon horizontal axles in suitable bearings,
with handles for hand driving. Other means of turning such wheels may, however,
be used, such as steam, gas, or other engines, and such wheels may be turned in
contrary directions when required. Suitable driving pullies are fitted to the axles
of these driving wheels with as many grooves as may be required.
At the bottom of each ice tub there is fitted a central wooden boss or bearing in
which the centre pins of the earthenware freezes work. Above the ice tubs there
are fitted metallic frames (which can be removed at pleasure) with holes acting as
bearings to the upper ends of the freezers. The axes of the freezers are therefore
vertical, and the axes of the driving pullies are horizontal. The freezers are caused
to revolve by means of catgut or other driving bands leading from the driving
pullies on the fly wheel axles to the sheaves or pullies mounted upon the covers of
the freezers.

page_text: When required any one or more of the freezers may be caused to cease revolving
by throwing off the band or bands, when the covers can be removed and the
contents taken out.
The glass, earthenware, or porcelain freezers are made cylindrical, closed at the
lower ends, and are each cast or formed with a projecting pin or centre point under-
neath upon which they revolve. The upper open end is fitted with a movable
cover, metallic or otherwise, having a driving pulley and central pin upon which
they also revolve.
The diameter of each ice tub is sufficiently larger than that of the freezer to
enable the proper amount of ice or other refrigerating material to be placed therein,
surrounding the freezer, and a suitable tap or plug is fitted to each tub at or near
the bottom for emptying the same when required.

the said Charles France in the Great Seal Patent Office on the 17th February

CHARLES FRANCE, of No. 28, Rosoman Street, Clerkenwell, in the County of
Middlesex, Fitter. "IMPROVEMENTS IN APPARATUS FOR MANUFACTURING ICES,
ICE CREAMS, AND OTHER ANALOGOUS PURPOSES."
The objects of my said improvements are to promote cleanliness and afford
increased facilities in revolving the freezers of ice making apparatus. The former
I secure by making the revolving freezers (by preference) of glass, earthenware,
or porcelain, porous or otherwise, and the latter by the arrangements for mounting
herein after mentioned.
In carrying out my said Invention I fit into a suitable table or frame one or
more (by preference four) ice tubs. When four are used I arrange these tubs
two at each end of the table, and mount upon the table two fly-wheels upon hori-
zontal axles, in suitable bearings, with handles for hand driving. Other means of
turning such wheels may, however, be used, such as steam, gas, or other engines,
and such wheels may be turned in contrary directions when required. Suitable
driving pullies are fitted to the axles of these driving wheels with as many grooves
as may be required.
At the bottom of each ice tub there is fitted a central wooden boss or bearing
in which the centre pins of the freezers work. Above the ice tubs there are fitted
metallic frames (which can be removed at pleasure) with holes acting as bearings
to the upper ends of the freezers. The axes of the freezers are therefore vertical,
and the axes of the driving pullies are horizontal. The freezers are caused to
revolve by means of catgut or other driving bands leading from the driving pullies
on the flywheel axles to the sheaves or pullies mounted upon the covers of the
freezers.
When required any one or more of the freezers may be caused to cease revolving
by throwing off the band or bands, when the covers can be removed and the
contents taken out..
The freezers, whether made of glass, earthenware, porcelain, metal, or other
material, are made cylindrical, closed at the lower ends, and are each cast or formed
with a projecting pin or centre point underneath, upon which they revolve. The
upper open end is fitted with a movable cover, metallic or otherwise, having a
driving pulley and central pin, upon which they also revolve.
The diameter of each ice tub is sufficiently larger than that of the freezer to
enable the proper amount of ice or other refrigerating material to be placed therein,
surrounding the freezer, and a suitable tap or plug is fitted to each tub at or near
the bottom for emptying the same when required.
And in order that my said Invention may be clearly understood I will proceed
to describe the same more particularly by the aid of the accompanying Drawings,
in which similar letters of reference indicate similar parts.
Fig. 1 is an elevation, partly in section, of my apparatus; Fig. 2 is an end view
of the same, and Fig. 3 is a plan or top view of the same.
a is the stand. This is shewn in the Drawings as mounted on tressels for
stationary purposes, but it is sometimes mounted on wheels so as to be portable,
and can be fitted with shafts for a horse, or otherwise driven; b, b, are the ice
tubs; c, the boss or bearing in which the freezers work; d, d, are the metallic
frames fitted to the tubs, as shewn; the upper horizontal part of this frame can be
removed by withdrawing the pins e, e. By removing these pins the horizontal bar
can be taken off and the freezers removed in order to take out the contents. The

page_text: covers ff, of the freezers are made to fit tightly upon the freezers, and the pullies g, g,
actuate the lids, by which means the freezers are caused to revolve in the ice
tubs; h, h, are the standards upon which the driving axles are mounted. There
are two axles shewn in the Drawings with a handle to each, in order that one may
be in action while the other is at rest, or both may be operated at the same time;
i, i, are fly wheels mounted on the axles, and I, le, are the driving pullies fixed
upon the axles with grooves therein for the driving bands. At 1, 7, suitable pullies
are mounted, as shewn, to lead the driving bands to their respective pullies; at m
there is the usual plug for drawing off any water that may accumulate in the
ice tubs.
Having now stated the nature and objects of my said Invention, and in what
manner the same is to be performed, I would have it understood that what I claim
as my Invention and desire to be secured to' me by the herein before in part recited
Letters Patent is,―
1st. The use and construction of revolving freezers mounted and actuated in the
manner herein before described and shewn on the Drawings, or any mere
modification thereof.
2nd. The general arrangement and combination of parts respectively, together
forming my improvements in apparatus for manufacturing ices, ice creams, and
other analogous purposes.
In witness whereof, I, the said Charles France, have hereunto set my hand
and seal, this Seventeenth day of February, in the year of our Lord One
thousand eight hundred and eighty one.
CHARLES FRANCE. (L.S.)
