I, HORACE HOLDEN, of East Orange, Essex County, State of New Jersey, United
States of America, gentleman, do hereby declare the nature of this invention to be as
follows:-
:―
This invention relates to a sounding lead for mariners use, which is so constructed,
that the ground taken up by the arming will be protected while being drawn upwards
through the water. Thus the ground will not be apt to be partly or entirely washed
away before it reaches the surface.
The lead is of conical or other shape and has a cavity at its bottom for the
reception of the arming.
Around the lead there is placed a sleeve open on top and bottom and free to slide

the sleeve will drop down, to surround the arming and protect it and the ground
from being washed away.

page_text: Improvements in Sounding Lead.
I, HORACE HOLDEN, a citizen of the United States of America, residing at East
Orange, Essex County State of New Jersey, gentleman, do hereby declare the
nature of my invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
This invention relates to a sounding lead for mariner's use, which is so constructed
that the ground taken up by the arming will be protected while being drawn upwards.
through the water. Thus the ground will not be apt to be partly or entirely washed
away before it reaches the surface.
The invention consists in the various features of improvement more fully pointed
out in the claim.
In the accompanying drawing :"
Fig. 1 is a side view of my improved sounding lead, showing the sleeve down.
Fig. 2 is a vertical longitudinal central section of fig. 1.
Fig. 3 is a similar section as fig. 2 but with the sleeve up.
The letter a, represents a sounding lead of conical. or other suitable shape and
having a cavity in its bottom, to receive the arming b, as usual.
Around the lead a, there is placed a sleeve d, open at top and bottom and having
preferably a flange e, at its upper. end.
The sleeve d, is free to slide up and down on lead a. Its upward motion is
limited by screws or stops f, projecting laterally from the lead a. The downward
motion of the sleeve d, is limited by the flange e, when closely embracing the
conical body of the lead a, or by a laterally projecting flange g, at the bottom of the
lead.
The operation of the device is as follows:
The lead, being dropped, will pass swiftly through the water, so that the resistance
of the water, acting against the lower edge of the sleeve d, will force the same
upwards, until its flange e, strikes against the stops f. The sleeve is of such a length
only, that in this position the cavity, with its arming b, will be exposed (fig. 3) so
that as the lead strikes the ground, the latter can come into contact with and adhere
to the arming.
The lead being next, raised, the gravity of the sleeve, together with the pressure of
the water on its upper edge will cause it to drop down into the position shown in
fig. 2, so as to project beneath the base of lead. Thus the arming and ground
will be protected against all currents and the ground may thus be raised to the
surface without being washed away.
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. The combination of a sounding lead, with a sleeve surrounding said lead and
free to slide thereon, substantially as specified.

page_text: 2. The combination of a sounding lead, with a sleeve surrounding said lead, and
with stops that limit the upward and downward motion of the sleeve, substantially as
specified.
3. The combination of a conical sounding lead, with a sleeve embracing said lead
and having flange e, and with the stop f, substantially as specified.
4. The combination of a sounding lead a, with a surrounding sleeve d, having
flange e, and with the stop f, above sleeve d, and with the laterally projecting
flange g, at the lower end of the lead a, substantially as specified.
