T 0 all whom it may concern:

Be it known that I, SiirnoN' B.v SMITH, a citizen of the United States, residing at New London, in the 'county of New London State of Connecticut, have invented certain new and useful Improvements in Sounding Apparatus for Submarine Boats; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art, to which it appertains to make and use the same.

The present invention relates to sounding apparatus for submarine boats for determining the depth of the sea'while the boat is still or in motion on the surface of'the sea or submerged therein, and the primary object of the invention is to provide coacting means carriedby the boat and by the lead of the sounding apparatus to form a substantially water-tight closure to the sea for the pocket in which the lead is stowed. Accordingly, whenever the sounding apparatus is not in use, the pocket containing the'lead is sealed in a substantially water tight manner to the sea and may be freed from water so that the stability-of the boat is in no wise affected, as may be'the 'case with a pocket of this kindopen to the sea.

Furthermore, the winding drum, which is usually located in thepocket also, is not exposed to the sea water when the sounding apparatus is not in use, and the depth gage carried by the lead may be more readily read from within the boat.

The invention also comprehends, in asso ciation with the pocket and the means for maintaining it Water-tight, suitable means for removing the water from the pocket after the lead is stowed therein, so that not only is the pocket closed to the sea whenever the sounding apparatus is not in use, but it may also be cleared of water at that time to further protect the apparatus in the pocket and to further assist in accurately reading the depth gage.

In the accompanying drawings illustrating the preferred form of my invention, Figure l is a central section through the sounding apparatus; and Figs. 2 and 3 are sections on lines 2-2 and 33, respectively, of Fig. 1.

The bottom of the hull of the submarine of a casing having a central cylindrical portion '3 closed at the top in a substan tially water-tight manner by an enlargement 1 for the winding drum, and having at its loweropen end an expanding section secured at the flanges 6 to theoutside of the hull.

T he lead has an upper cylindrical portion I 7 andia lower portion formed with fins or legs 8 terminating. in an upturned peripheral lip or flange 9. The ballast 28 of lead is firmly held as shown, and adds suiiicient' v weight to the lead to cause it to descend properlywhen the boat is still or in mo-. t on. The leadcarries a Kelvin gage 10', and a pin or knob 11 adapted to coact with v the helical fin 12 on the interior of the 'cy-. lindrical portion 3 of the pocket to bring the gage into position for viewing it from" Within'the boat when the water tight' door 13 is removed. If

The winding'drum isof the well-known type in which the drum proper M is mount: ed on the shaft 15. The shaft 15 projects through a water tight bearing16 into-'the interior of the boat, where it carries a pinerating handle 19. The winding drum is I also provided with the usualform of brake 20 for automatically stopping it when the lead reaches the bottom of the sea. The wire 21 is attached to the lead through a swivel joint at 22, thereby permitting, the

acting as a valve seat, is engaged by the up-v I U turned lip 9 acting as a valve body, to form V ion 17 meshed witha gear 18 having an opa valve closing the pocket to the sea in a substantially water-tight manner. The arrangement of the ring 23 and the peripheral. 7 hp 9 is such that notwithstanding the factwhen the leadis stowed in the pocket, the lead is free to descend immediately that the winding drum starts to pay out the wire 21.

The pocket is provided with a drain pipe 2 1- having a valve 25 therein, and with a pipe 26' communicating with a source of compressed air (not shown), and having avalve 27. When the lead is in stowed posii on they form a substantially water-tight jointtion, the water may be blown from the pocket through the drain pipe 24; by opening the

valves

25 and 27.

Having thus described my invention, what I claim is: V

1. In sounding apparatus for submarine boats in combination with the hull thereof, a pocket open to the sea through the bottom of the hull, a lead adapted to be stowed in the pocket, and a winding drum for the lead, said lead and boat cooperating to form a substantially water-tight closure to the sea.

2. In sounding apparatus for submarine boats in combination with the hull thereof, a pocket open to the sea through the bottom of the hull, a lead adapted to be stowed in the pocket, a valve seat carried by the boat, a valve body carried by the lead and cooperative with the seat toform a substantially water-tight closure to the sea, and a winding drum for the lead. Y

3; In sounding apparatus for submarine boats in combination with the hull thereof, a substantially water tight casing passing through the hull to form a pocket therein, a lead cooperating with the casing to substantially seal the pocket to the sea, and a winding drum for the lead arranged within the pocket.

' 4;. In sounding apparatus for submarine boats in combination with the hullthereof, a casing fastened. to the hull around a passage therethrough to form a pecket open to the sea, alead adapted to be stowed in the pocket, a valve seat arranged around the open end of the poeket,a flange carried by the lead in position to cooperate with the valve seat to form a substantially water-tight closure to the sea, and a winding drum for the lead.

' 5. Insounding apparatus for submarine boats in combination with the hull thereof, a casing passing through the bottom of the hull and being fastened on the outside thereof to form a pocket open to the sea, a valve boats in combination with the hull thereof, a.

pocket open to the sea through the bottom of the hull, a lead adapted tobe stowed in the pocket in such manner as to substantially sealthepocket to the sea, a winding drum for the lead, and means for removing Water from the pocket when the lead is stowed therein. v c

7. In sounding apparatus forsubmarine boats in combination with the hull thereof, a pocket open to the sea through the bottom of the hull, a lead adapted to be stowed in the pocket in such manner as to substantially seal the pocket to the sea, a winding drum for the lead, and means for blowing water from the pocket when the lead'is stowed therein, comprising a drain pipe leading from the pocket and a pipe for discharging compressed air into the pocket.

8. In sounding apparatus for submarine boats in combination with the hull thereof, a substantially watertight casing passing through the hull to form apocket therein, a lead cooperating with the casing to substantially. seal the pozhot to the sea when the lead is stowed inthe pocket, a winding drum for the lead arranged within the pocket, and means for. removing water from the pocket when the lead is stowed therein.

In testimony whereof I afiix mysignature.
