NOW KNOW YE, that I, the said Joseph Gardner, on behalf of myself

Hargrove, and Samuel Hargrove, jun', do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to be
ticularly described and ascertained in and by the following statement :-
Our Invention consists of a new or novel mode by which sheaves and bushes
may be made or manufactured, that is to say, we cast from patterns of required
shape in malleable cast iron a sheave or bush, provision being made in each
case for the reception of a series of rollers which are placed in the body or
centre of the sheave or bush and revolvo upon the sheave pin, and are kept
apart in the following manner:-We make use of two metallic rings with
cone or other centres cast on to correspond with concave or hollow rollers
and protected by grooved plates in which they revolve.
Having now described the nature of our said Invention, and the manner
of carrying the same into effect, we wish it to be understood that we do not
limit ourselves to the precise method herein described, as the same may be
varied without departing from the nature of our said Invention,―
1st, we claim as our Invention the application of malleable cast iron for
sheaves for ships and other pulley blocks, which may be galvanized or
enammeld.
2nd, we claim the sheave bush for pulley blocks in the following arrange-
ments, that is to say, the bush having flat or grooved surfaces internally, in
which are inserted two metallic rings with slides for the rollers to revolve
upon the sheave pin.
In witness whereof, I, the said Joseph Gardner, on behalf of myself and
the said Richard Lee, George Henry Wain, Samuel Hargrove,
Charles Hargrove, and Samuel Hargrove, jun', have hereunto set my
hand and seal, this Eighteenth day of October, in the year of our Lord
