Description

UNITED STATES PATENT OFFICE.
PETER TALBOT PETERSON, OF BROOKLYN, NEW YORK.
soUNDINe-Ll-:AD-
SPECIFICATION forming part of Letters Patent No. 515,128, dated February 20, 1894.
Application filed November 19l 1892. Serial No. 452,504. (No model.)
To all whom Zt may concern.-
Be it known that I, PETER TALBOT PETER- son, a subject of the Queen of Great Britain, residing at No. 226 Fifty-third street, in the clty of Brooklyn, in the county of Kings and State of New York,have invented a new and useful Sounding-Lead, of which the following 1s a specification. n
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 thereafter 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 claims.
In the accompanying drawingsz-Figure l is a side-view of the lead showing the sleeve down. Fig. 2 is a vertical longitudinal central section of Fig. 1. Fig. 3 is avertical longitudinal central section of Fig. l 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 hereinafter described.
o is a cylindrical sleeve open at .the bottom, and so fitted to the lead in its upper part as to prevent any movement downward, and held in place at its upper extremity by the pin e, which prevents any movement upward.
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 the lower end of the sleeve c.
sleeve b, upon which bearings the sleeve b 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 b by accommodating the diameter of the iiange d to the diameter of the lower section of the sleeve b. This sleeve b is supplied with a liange h projecting outward 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 upper section of this sleeve is supplied with a flange t' projecting inward from the surface of the sleeve, and so fitted as to rest upon the ange d and washer when the sleeve b is down, thus limiting the downward motion of the sleeve b.
kThe sleeve c is so fitted to the sleeve b 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 b 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 b and the flange h will force the same upward until its shoulder strikes against 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 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 hwill 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.
What I claim is- 1. The combination of a sounding-lead with a sliding sleeve b surrounding the same and 3. The kcombination of a. sounding lead a, adaptedto be projected beyond its base, subhaving `a ange d with a sleeve b having a lo Stantially as speeied. shoulder and flange h and sleeve or cap c with 2. The combination of a sounding-lead a, a pin e substantially as specified.
having a, flange d with a cylindrical sleeve b PETER TALBOT PETERSON.
having the shoulder and flange h and the Witnesses:
ange i and the sleeve or cap c with the pin HOWARD C. TRACY,
e substantially as specified. JOSEPH IMMERMAN.
