Sleeve Sounding Lead.
I, PETER TALBOT PETERSON, residing at No. 226 Fifty-third Street in the City
of Brooklyn in the County of Kings and State of New York, by occupation a
Marine Surveyor, do hereby declare the nature of my invention for A SLEEVE
SOUNDING-LEAD, 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 use in ascertaining the nature of
deposits lying under water, so constructed that the portion of the deposit attached
to the arming upon contact therewith will be protected while the lead is being there-
after drawn to the surface of the water. Thus the portion of the deposit attached
to the arming will not be apt to be washed away therefrom during its passage to the
surface of the water. The invention consists in the various features of improvement
more fully pointed out in the claim.
:-
In the accompanying drawing :-
Figure 1 is a side-view of the lead showing the sleeve down.
Figure 2 is a vertical longitudinal central section of Figure 1.
Figure 3 is a vertical longitudinal central section of Figure 1 but with the
sleeve up.
The letter a represents a sounding-lead of suitable shape, having the usual cavity
in the bottom to receive the arming. b is a cylindrical sleeve open at the top and
bottom having a smaller diameter in its upper part than in its lower, the two parts
of which are connected by a shoulder. It surrounds the lower part of the lead and
is free to travel on it as hereafter described. c is a cylindrical sleeve open at the
bottom, and so fitted to the lead in its upper part as to prevent any movement
downwards, and held in place at its upper extremity by the pin e, which prevents
any movement upwards.
The lead a is of a cylindrical shape, supplied with a flange d at the bottom and
tapering at the top from a point immediately below the hole for the pin e.
It may
be supplied with raised bearings upon its cylindrical surface above the flange d
accommodated to the diameter of the upper section of the sleeve b, upon which
bearings the sleeve is free to move. The upper surface of the flange d is supplied
with a washer fitted to a suitable depression in the lead. Bearings are supplied for
the lower part of the sleeve by accommodating the diameter of the flanged to the
diameter of the lower section of the sleeve b.
This sleeve bis supplied with a flange projecting outwards at the shoulder for
the purpose of affording additional resistance to the water in descending or
ascending, thereby keeping it more securely in the desired position. The lower
section of this sleeve is supplied with a flange i projecting inwards from the surface
of the sleeve, and so fitted as to rest upon the flange d and washer when the sleeve b
is down, thus limiting the downward motion of the sleeve b.
The sleeve c is so fitted to the sleeve as to restrict its upward motion when
coming in contact with the shoulder. It is closely fitted at its upper end to the
lead a, and overlaps the lower sleeve when the latter is down thereby preventing
partly or entirely the entry of a current of water or solid substances at the top of
the sleeve b.
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 and the flange h will force
the same upward until its shoulder strikes against the lower end of the sleeve c.
The sleeve b is of such a length only that in this position the cavity of the lead with
its arming will be exposed, Fig. 3, so that as the lead strikes the deposit the latter

page_text: can come in 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 the flange h
will cause it to drop down into the position shown in Fig. 2, so as to project
beneath the base of the lead. Thus the arming and ground will be protected
against all currents, and the deposit 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. A cylindrical sounding-lead constructed with a flange at the lower end, having
a recess as usual in the bottom.
2. A combination of a sounding-lead with a sliding sleeve surrounding the same
and adapted to be projected beyond its base, substantially as specified.
3. A combination of a sounding-lead a having a flange d with a cylindrical
sleeve having the shoulder and Hange and the flange with the pin é substan-
tially as specified.
4. A combination of a sounding lead a having a flange d with a sleeve bhaving
a shoulder and flange and sleeve or cap c with a stop e substantially as
.specified.
5. A combination of a sounding-lead a with or without raised bearings having a
flanged and a sleeve b having a shoulder and flange h and a sleeve and stop e
substantially as specified.
6. A flange as applied to a sleeve for sounding leads substantially as
specified.
7. A combination of a protecting sleeve or cap c and a sleeve b for sounding
leads, substantially as specified.
8. A combination of a sounding lead with a sliding sleeve arranged to project
beyond the base of the lead so as to protect the deposit on the arming while being
drawn to the surface of the water.
