IMPROVEMENTS IN ICE MOULDS AND IN THE METHODS OF THEIR CONSTRUCTION
Year: 1884

page_text: I SAMUEL PUPLETT of Westmoors Knowle in the county of Warwick Engineer
do hereby declare the nature of my said invention for IMPROVEMENTS IN ICE
MOULDS AND IN THE METHODS OF THEIR CONSTRUCTION to be as follows:-
With Ice Moulds of the usual form and construction difficulties frequently arise
from leakage caused by rivets and seams and the more serious difficulty of removing
the ice from the moulds occasioned by the bulging of the mould and from the
projecting parts of seams and rivets thereby necessitating excessive heating before
removal can be effected-The object of my Invention is to obviate these difficulties
and this I effect in the manner hereinafter described reference being had to the
accompanying drawing and to the letters of reference marked thereon.
In place of forming the moulds by rivetting, double seaming, or locking, I
construct the moulds without seam or rivet-The material may be plates of Copper
Iron or Mild Steel of suitable thickness by preference I recommend the mild steel
as it is easily worked and can be procured with a very smooth surface and it readily
takes on a coating of Copper, Tin or Zine by either of the well known processes
now in use-I form the moulds from three pieces namely two for the body of the
mould and one for the bottom-the two pieces first named after being cut to the
correct outline (6 figure 1)-have their edges (a) scarfed in the direction as shewn
and are then bent at right angles or at an angle something more than 90°-By one
method the scarfed edges of the two so bent plates are then brought together with
a slight lap and united by welding-By another method the scarfed edges are
brought nearly together and a strip or rod of iron or steel is interposed and the
parts are then united by welding-The edges and sides of the third piece forming
the bottom after being cut to a suitable outline (ɓigure 4) are bent or formned to
that extent (figure 5) that when formed it has an outline equal to the internal
dimensions of the body of the mould at the bottom-this piece so formed is then
inserted in the bottom of the mould with the flanged sides outward (C figure 6)
and in this position is perfectly joined to the body also by welding-Another
method of producing a similar result is, with the same number of pieces formed or
bent in the same manner but in place of scarfing the edges for welding they are
dovetailed (figure 7) or otherwise firmly secured and then united by braizing-by
both methods moulds may be formed perfectly tight and free from rivet or seam.

page_text: In all cases where ice is formed within the mould there is more or less trouble
caused by bulging-to overcome this difficulty I provide external stiffeners
(d figure 8) formed of L iron or such other section as will give the greatest support
with the least obstruction to the circulation of the brine-Inasmuch as there are
no seams or rivets to interfere, these stiffening bands can be readily and closely
fitted to the body of the mould thereby giving effective support-It will be readily
seen that by the methods and in the manner described a substantial and durable
mould can be made with a wide range of form and size without seam or rivet
perfectly tight and free from bulging and from which the ice can be removed with
the very minimum application of heat.

page_text: I SAMUEL PUPLETT of Westmoors Knowle in the County of Warwick Engineer
do hereby declare the nature of my invention for IMPROVEMENTS IN ICE MOULDS
AND IN THE METHODS OF THEIR CONSTRUCTION and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
With ice moulds of the usual form and construction difficulties frequently arise
from leakage cause by rivets and seams and the more serious difficulty of removing
the ice from the moulds occasioned by the bulging of the moulds and from the
projecting parts of seams and rivets thereby necessitating excessive wetting before
removal can be effected.
The object of my invention is to obviate these difficulties and this I effect in
the manner hereinafter described reference being had to the drawings accompanying
my provisional Specification and to the letters of reference marked thereon.
In place of forming the moulds by rivetting double seaming or locking I
construct the moulds without projecting seam or rivet, the material may be plates
or sheets of copper iron or mild steel of suitable thickness by preference I
recommend the mild steel as it is easily worked and can be procured with a very
smooth surface and it readily takes on a coating of Copper tin or zinc by either
of the well known processes now in use.
I form the moulds from three pieces namely two for the body of the mould and
one for the bottom the two pieces first named after being cut to the correct
outline b. Fig 1 have their edges a scarfed in the direction as shewn and are then
bent at right angles or at an angle something more than 90°.
By one method the scarfed edges of the two parts so bent are then brought
together with a slight lap and united by welding or by another method the scarfed
edges are brought nearly together and a strip or rod of iron or steel is interposed
and the parts united by welding.
The edges and sides of the third piece forming the bottom after being cut to
suitable outline fig 4 are bent or formed to that extent Fig 5 that when formed it
has an outline equal to the internal dimensions of the body of the mould at the
bottom This piece so formed is then inserted in the bottom of the mould with
the flanged sides outward C Fig 6 and in this position is perfectly joined to the
body also by welding.
Another method of producing a similar result is with the same number of pieces
formed or bent in the same manner but in place of scarfing the edges for welding
they are dovetailed Fig 7 or otherwise firmly secured and then united by brazing.
By both methods mould may be formed perfectly tight and free from projecting
rivets and seams.
In all cases where ice is formed within the moulds there is more or less trouble
caused by bulging to overcome this difficulty I provide one or more external
stiffeners & Fig 8 formed of L iron or such other section as will give the greatest
support with the least obstruction to the circulation of the brine.
Inasmuch as there are no seams or rivets to interfere these stiffening bands can
be readily and closely fitted to the body of the mould thereby giving effective
support against the tendency to bulge.
It will be readily seen that by the methods and in the manner described a
substantial and durable mould could be perfectly tight and free from bulging
without projecting seams or rivets and from which the ice can be removed with the
very minimum application of heat.

page_text: I dont restrict myself to particular forms or sizes as it will be obvious that these
may be varied without departure from the methods of construction hereinbefore
described.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First, Constructing ice moulds from iron or steel plates or sheets without
projecting seams or rivets by uniting the parts by welding substantially as
herein before described.
Second, Constructing ice moulds without projecting seams or rivets from plates
or sheets of various metals uniting the parts by brazing substantially as herein before
described.
Third, Constructing ice moulds with stiffening bands of such section as will
give effective resistance to the tendency to bulge and yet offer little or no
obstruction to the circulation of the brine around and by the moulds substantially
as shewn and for the purposes described.
Fourth, The combination of ice moulds without projecting seams or rivets with
stiffening devices to prevent bulging for the purposes herein before described.
Dated this 21st day of October 1884.
