I, ARTHUR HODGKIN SCAIFE, of Constantinople, in the Empire of Turkey, Agent
for Lloyd's, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to effect improvements in means and appliances for
lifting or hoisting blocks of ice.
In carrying out my Invention, I attach or suspend a horizontal pole or bar, to the
lower pulley block of the jib, traveller, crab, or other equivalent machine for hoisting;
such pole or bar being slung by means of chains, ropes or otherwise I attach to this
pole as many blocks of ice as it can conveniently accommodate, and hoist the same at
one and the same time.
The blocks of ice are attached to hooks fixed to the pole, in convenient positions.
For this purpose I use chains, ropes, rods or hooks, which are pressed into the substance
of the blocks, and caused to enter into the ice a sufficient distance below the outer
surface to ensure safety in hoisting, in the manner well understood as the melting of
ice under pressure, and refreezing; whereby the slings are securely held in position,
and, when being hoisted, the block of ice has no tendency to slip out of the attachments
or slings by which it is suspended.

ARTHUR HODGKIN SCAIFE, of Constantinople in the Empire of Turkey, Agent
for Lloyd's, do hereby declare the nature of my said invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of my invention is to effect improvements in means and appliances for
lifting or hoisting blocks of ice.
In carrying out my invention, 1 attach or suspend a horizontal pole or bar, to the
lower pulley block or chain of the jib, traveller, crab, or other equivalent machine
for hoisting such pole or bar being slung by means of chains, ropes or otherwise.
I attach to this pole as many blocks of ice as it can conveniently accommodate, and
hoist the same at one and the same time.
;
The blocks of ice are attached to hooks fixed to the pole, in convenient positions.
For this purpose I use chains, ropes, rods, wires or hooks, which are pressed into
the substance of the blocks, and caused to enter into the ice a sufficient distance below
the outer surface to ensure safety in hoisting, in the manner well understood as the
melting of ice under pressure, and refreezing; whereby the slings are securely held
in position, and, when being hoisted, the block of ice has no tendency to slip out of
the attachments or slings by which it is suspended.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawing, in which a is the lower pulley
block of a jib or traveller, b is a pole or bar, slung to the pulley block a, c c are the
ropes or other attachments for securing the blocks of ice d d in the manner herein
before described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The improved method of lifting or hoisting a number of blocks of ice, by means of
a horizontal pole or bar attached to the lower pulley block or chain of the jib, traveller,
crab, or equivalent hoisting apparatus; the blocks of ice being slung to the pole by
means of chains, ropes, rods, wires or hooks, substantially as herein before described
and illustrated by the drawing.
