PERCY SEAFORTH HUDSON, OF WATER/LOO, NEAR LIVERPGOL, ENGLAND.
APPARATUS FUR TAKING SOUNDINGS.
To ILZZ whom it may concern:
Be it known that I, PERCY SEAFORTH HUD- son, a subject of the King of Great Britain, residing at Waterloo, near Liverpool, in the county of Lancaster, in the Kingdom of England, have invented certain new and useful Improvements in Apparatus for Taking Soundings, of which the following is a specification.
This invention relates to apparatus or means for taking soundings, more particularly for use in deep water, and consists in providing means whereby practically all the specimens collected are retained until the apparatus has been drawn on board, thus enabling a correct record to be obtained of the substances at the bottom of the water.
The invention also conslsts lIl provldlng means for enabling soundings to be taken irrespective of the speed at which the vessel is moving.
The invention will be better understood with reference to the accompanying drawings, in which Figure 1 is a longitudinal section of the apparatus showing the bag in a collapsed condition; Fig. 1 a plan of the basket or cup; Fig. 2, a longitudinal section showing the bag extended; Fig. 3, a longitudinal section of a modification.
In the drawings, A is a grab, basket, cup or the like, secured to one end of a rod or spindle B, the other end of said rod or spindle B being attached to or fixed into a lead or sinker C, and held in position thereon by means of a lock-nut or the like D. The basket or cup is preferably tapering in form, the taper extending from the base to the upper edge. Slots or serrations E are arranged at the mouth or periphery of the basket A, by means of which a better sample of the sand or the like can be collected in the basket A, during the passage of the apparatus along the bottom of the sea. A cutout or hollowed port-ion F is provided at the bottom of the basket A, for the reception of a bag G of linen or any other suitable material, said bag G being retained in said part F by means of a ring or rod H and a cover or cap I, the cap or cover I being preferably provided with a milled edge. The linen bag G is capable of expansion, as will be hereinafter described. A bossor bridge J is provided inside the cup 01 basket Specification of Letters Patent.
Application filed May 16, 1910.
Serial No. 561,686.
A, into which boss J, one end of the spindle or rod B is secured, thus connecting the basket A to the sinker C. The rod B not only serves as a connection between the basket A and sinker C. but it also acts as a guide rod on which a buoyant valve K can slide, and which valve K, on the apparatus being thrown into the water, is raised off its seat on the basket A and remains in its raised. position until the apparatus is commenced to be hauled in, when, owing to the pressure of water on the upper surface of said valve K, the latter is pressed down again on to the basket A, thereby entrapping the contents in the latter.
In the forms of construction shown in Figs. 1 and 2, the valve K is shown as fitting outside or over the edges of the basket A, and also as being hollowed out on its underside to enable vthe serrations E or upper edge of the basket A to be completely inclosed when the valve is in its lowermost position.
In Fig. 3 is shown a modification of the valve K. In this figure the valve is shown as fitting inside and below the serrations E in the mouth of the cup A, and a packing or washer M of felt or any other suitable material provided thereon. By this means a perfectly tight joint can be made on the valve K reaching its lowermost position.
To prevent the inrush of water down the space between the rod B and valve K, a packing or washer L of felt or any suitable material is arranged, either on the spin dle B immediately above the boss J, or the packing may be arranged on the upper side of the boss itself, or an apron or hood N of linen, canvas or any other suitable material, may be provided above the top of the valve as shown in Fig. 2, the lower ends of the hood N being preferably curved outward as at O. A packing P of any suitable material may also be arranged on the inside of the valve K whereby an additional security for the making of a tight joint at the point where the valve K overlaps the serrations E of the basket A, as shown in Fig. 1, is afforded. I
To enable a sounding to be taken irrespective of the speed at which the vessel is traveling, and also with a view of preventing the lead C and basket A from becoming detached from the line, a spring S is attached to the lead C at one end by means of a hook Patented July 18, 1911.
or bolt T, and at the other end to the rod line in any suitable manner. The spring S is preferably spiral in form, but ofcourse other forms of spring may be employed.
The method of using the apparatus is as follows: On the apparatus being thrown into the water, the latter forces or lifts up the valve K on its red B, until it reaches the nut I), thereby uncovering the basket A. On reaching the bottom of the water the apparatus falls on its side and on being drawn along, the bag is caused to open out, thus collecting and retaining specimens of the sand, shell or the like. Immediately the apparatus is commenced to be withdrawn from the water, the valve K is forced down by the pressure of water on to the basket A thereby preventing the escape of the contents from the bag G. To release the contents of the bag G, the cap I at the base of the cup A is unscrewed, when the bag can be withdrawn, and it will be found that a very large quantity of material has been collected, and owing to the bag G being of a porous nature most of the water collected therein will also be found to have escaped, thus leaving practically a solid sample. To replace the bag after the contents have been examined, it is only necessary to insert it in the hollow F of the basket A and screw the cap I on again.
