DUGALD MORRISON 10 Edgcumbe Street Stonehouse in the County of Devon
Fishing Tackle Manufacturer do hereby declare the nature of this invention to be
as follows:-
The principle admits of a graduated increase of weight at a time up to any
aggregat weight. The adjustable sinkers are so fitted that at all intermediate
weights, between maximum and minimum-it is neat & workable. The portions of
it are.
A brass rod bent at right angle in the middle and having one coil at the
angle. At one extreem end of the rod a loop is formed and brazed. The other is
sealed in a hemispherical lead having its flat side upwards. Above this lead slides
on the rod a lead of the shape of a pear from which the upper half has been cut.
This when slid down to the fixed lead makes a neat pearshaped lead of the minimum
weight.
A set of flat detachable weighs is provided slotted to the center a circular
enlargement of the slott in each lead is made. On the lower side of each lead,
towards the edge is a projection which fitts exactley into the circular enlargment
in aney other of the detachable leads. Thus aney number may be slipped on, each
locking into that below it and all kept firm by the sliding cap above.

COMPLETE SPECIFICATION.
Improvements in Leads for Sea Fishing.
I, DUGALD MORRISON of 10 Edgcumbe Street Stonehouse in the County or
Devon Fishing Tackle Manufacturer 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 relates to improvements in leads for sea fishing & consists of a
lead or sinker constructed of suitable material so arranged that it may be easily and
readily increased in weight or lightened according to the requirements of the
varying conditions pertaining to sea fishing. For this purpose i employ a lead or
sinker formed of lead or any suitable material constructed as follows. An upright
wire or rod A provided with an eye F or suitable arrangement for attachment to
the line E is firmly fixed in a mass of lead B of an hemispherical form which forms
the lower portion of the lead or sinker. Free to slide on the wire or rod is another
mass of lead C or any suitable material. The combination of these two portions of
lead forms a lead or sinker of least minimum weight. I also employ flat cylindrical
pieces of lead D which are provided with a slot, or groove G extending from the
outside to the centre for the purpose of easily passing it on, and off, the upright
rod or wire, A. These flat cylindrical pieces take up an intermediate position,
between the two larger portions of the lead B. C and the combination of the top,
and bottom pieces B & C and the intermediate, flat portions D forms the lead, or
sinker, of greatest maximum weight. The method I employ for the purpose of
locking or holding the various loose portions D together is as follows, each loose
portion, is provided with a round lug or projection H and also with a circular
SU 677

of the adjoining piece. The accompanying drawings will clearly explain the
construction of my invention.
Fig. 1. shews a view in elevation of a lead or sinker of greatest weight.
Fig. 2. shews a view in elevation of the lead or sinker, with the intermediate
portions Dremoved, shewing a lead or sinker of the least minimum weight.
Fig. 3. shews in elevation the lead or sinker with one of the flat intermediate
pieces D removed.
Fig. 4. shews a view in elevation of one of the flat intermediate pieces D of the
sinker and shewing the projection or lug H.
Fig. 5. shews a view in plan of one of the intermediate pieces D.
It will be clearly seen that in using the lead, or sinker, for sea fishing, the
varying effects of tides requiring greater or less weights, may be easily, and readily
compensated for, by removing, or replacing, the loose weights D of the lead, or
sinker, as may be best required to suit the circumstances at the time and
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.
First. A lead or sinker for sea fishing constructed of lead or any suitable
material formed in parts which may be readily removed or replaced as may be
required, substantially as herein described.
Secondly. In a lead or sinker for sea fishing a combination of loose weights
formed with projections and corresponding recesses for the purpose of interlocking
and holding together substantially as herein described.
