METHOD OF ADAPTING AND APPLYING * DANDY SCORE SHEAVES' TO FISHING
SMACKS," to be as follows:-

Our invention has for its object the adaptation and application to fishing
smacks of an improved arrangement of "dandy score sheaves" whereby the
excessive strain now put upon the smack's quarter, when heaving the trawl beam
tight up, may be lessened.
And our invention consists in the substitution for the "dandy score sheave" now
in use with a single lead over a sheave or guide fixed at the stern part of the
smack, of two sheaves or pulleys one horizontal and the other vertical round or
over which the hauling chain is led and caused to travel, thereby easing the strain
upon the smack's quarter. The said sheave or pulley that works horizontally is
mounted in a box securely fixed to the smack, such box being open at each side for
the passage of the chain, and the sheave or pulley that works vertically is mounted
in suitable bearings so placed in relation to the said open box as to facilitate the
passing of the chain from one sheave or pulley to the other in the manner
required.

'
METHOD OF ADAPTING AND APPLYING 'DANDY SCORE SHEAVES TO FISHING
SMACKS and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our Invention has for its object the adaptation and application to fishing smacks
of an improved arrangement of "dandy score sheaves" whereby the excessive strain
Dow put upon the smack's quarter when heaving the trawl beam tight up may be
lessened.
And our Invention consists in the substitution for the dandy score sheave" now
in, use with a single lead over a sheave or guide fixed at the stern part of the
smack of two, sheaves or pulleys one horizontal and the other vertical round or
over which the hauling chain is led and caused to travel, thereby easing the strain
upon the smack's quarter. The said sheave or pulley that works horizontally is
mounted in a box securely fixed to the smack such box being open at each side for
the passage of the chain, and the sheave or pulley that works vertically is mounted
in suitable bearings so placed in relation to the said open box as to facilitate the
passing of the chain from one sheave or pulley to the other in the manner
required.
In order that our Invention may be fully understood we will describe it
more particularly by the aid of the accompanying drawings in which is represented
the improved "dandy score sheave" above referred to.
Fig. 1 is a deck view and Fig 2 a stern view of a portion of a fishing smack
with the improvements applied thereto.
In these figures A is the sheave or pulley that works horizontally within the
box B bolted through a flange to the stern part of the smack, C is the sheave or
pulley that works vertically in bearings at D also bolted to the smack in such a
position as to be suitable for the hauling chain E to pass over the two sheaves or
pulleys as required. The chain E when hauled from the deck of the smack is
drawn over the sheave or pulley A, thereby drawing also a part of the chain over
the sheave or pulley C, by which arrangement the strain upon the smack's quarter
I will be eased as required.

Invention and in what manner the same is to be performed we declare that what
we claim is
The combination in a
"
dandy score aheave" of a borizontal sheave or pulley
with a vertical sheave or pulley respectively adapted for the working of the
hauling chain in the manner and for the purpose substantially as described.
