PROVISIONAL SPECIFICATION.
A Combined Block and Bull's Eye for Sails.
JOHN COOPER DODD, R.N.R. Master Mariner 3 Moorland Terrace Plympton
Devon do hereby declare the nature of this invention to be as follows:-
In a D-shape block or shell having a groove round the outside, I cut an opening in
which insert a roller or sheave, having its axis parallel to and in the same plane
as the straight side of the D.
This bull's eye is attached to the foot or leech rope of a sail by a cringle lying in
the outer groove of the D and the buntline, leechline or brail passes through the
block and over the sheave, thus travelling with little friction.

COMPLETE SPECIFICATION.
A Combined Block and Bull's Eye for Sails.
I, JOHN COOPER DODD, R.N.R. Master Mariner, 3 Moorland Terrace,
Plympton, Devon, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
My invention refers to combined blocks and bull's eyes for sails, as hereinafter
described, whereby I am enabled to greatly reduce the friction commonly incurred
by the travel of bunt-lines, leech-lines, brails, and the like, therethrough.
According to my said invention, I form an opening or openings in the block or
shell, in which opening or openings I mount a roller or rollers, sheave or sheaves,
upon or between which the said lines or ropes bear during their travel.
My invention will be readily understood by further describing same with reference
to the accompanying drawings, on which similar letters of reference refer to like
parts in the several Figures 1 to 5.
Fig. 1 is a front elevation, Fig. 2 a side elevation, and Fig. 3 is a central vertical
section, shewing my combined block and bull's eye for sails as applied to a D shaped
block or shell.
A is the D shaped block or shell, B is the groove formed around the outer edge
of same, C is the opening, cut or formed in the block A, D is the roller or sheave,
mounted on an axis or spindle D', the axis of the roller or sheave being at Figures 1
to 3 parallel with the straight side of the block.
Fig. 4 shews the block or shell A having two rollers or sheaves D D applied
thereto; in this case the outer edge of the block A is formed circular. The
combined block and bull's eye is shewn at Fig. 4 partially in section, in order to
indicate one of the axes D₁ of the rollers or sheaves D D; E E in Figs. 1 and 4
are recesses formed with a view of lessening the weight of metal. The combined
block and bull's eye Fig. 5 is practically similar to that shewn at Figs. 1 to 3 and
does not require further description in this Specification.
The combined blocks and bull's-eyes may be attached to the foot or leech rope
of sails by a cringle lying in the groove B, and the bunt-line, leech-line, or brail, or
the like, passes through the block A and over the sheave D, whereby the said ropes
are caused to travel with greatly less friction than heretofore. They can also be
attached to the upper side of yard on jackstay for bunt-lines and leech-lines to
reeve through, before going through the bull's eye on foot or leach of sail, or they
may be applied to sails or otherwise wherever they may be required.

page_text: 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 :-
1. A combined block and bull's eye for sails, constructed arranged and acting
substantially as and for the purposes set forth.
.
2. The combined block and bull's eye for sails, composed of a block or shell A
formed with a groove B, and having an opening C in the said block or shell, in
which opening is or are mounted a roller or sheave or rollers or sheaves D on
axes D', all substantially as shewn and described with reference to the accompanying
drawings.
3. The general combination and arrangement of parts composing my new or
improved combined block and bull's eye for sails, all substantially as herein
described and illustrated by reference to Figs. 1 to 5 of the accompanying drawings,
together with any mere modification or modifications thereof.
