The invention consists of on improved form of sounder 2.:Ll' ll16ftn3 for controlling and indicating the depth at which it travels and also improved means whereby the contact of the sounder against the bottom will be plainly indicated to the ear. The sounder of pcculior form and constructiomos will (lescribed farther on, and is held to the vessel by a, line wire said out from a registering reel.

This portion of the apparatus may be. secured in any desirable manner to the vessel, and any suitable means may be employed to indicate contact with the bottomas, for instance, the slackening or change of I prefer the apparatus shown in the drawings, consisting of a spar M, removably secured to the rail N of the vessel by engaging in a yoke N of strapiron and held by'a clamp M, compressing the inboard end of the spar firmly to the rail. The spar projects sufiiciently outboard to carry the wire and sounder clear of the vessel. Near the inboard end is a base-plate D, having a pair of standards D, serving as bearings for the shaft D of a reel D mounted between them. One end of the shaft carries a ratchet-wheel D, acted upon by a springpawl D serving to prevent unwinding when engaged, and also with a drum D and friction-band D therefor, operated by a handlever-D and forming-a brake to check the too-rapid unwinding when the pawl is disengaged.

The indications are read by means of a fixed index D mounted on the framing near the dial.
A gear-wheel I) on the drum is in mesh mountedin bearings onthe plateD. The other end of the counter-shaft is squared to receive a crank D, by which the reel maybe turned to wind up the Sustaining-wire B.
t On the outboard end of the spar is removably mounted a peculiarly-formed antifriction-wheel, over which the wire B passes in changing its direction from the horizontal to the vertical. The wheel consists of two circular disks 0 O mounted with freedom to revolve independently on a fixed center 0, carried in a yoke 0, attached to the spar. One of the disks is provided with a raised concentric portion on one face of smaller diameter than the disk, which matches to and is received in a corresponding but shallower circular recession the adjacent face of the other disk, thus producing a deep narrow groove in which the bight of the wire is guided and allowed to pay in or out with perfeet freedom, without friction, and with but little liability to catch or buckle.

plate 0 on which the yoke O is mounted.
The arm G is formed of two or more stiff helical springs. The cylinder lies transversely below the spar, with its outer rounded face held by the arm G in yielding but close contact with the wire B, and serves 'as a resonatorinau'gmenting the sound produced by vibrations of the wire. The variations and interruptions in the sound thus produced indicate to the trained ear of the attendant the contact of the submerged sounder with the bottom and may also indicate the character of the obstruction encountered or the nature of the surface if the sounder-be in rolling contact therewith.
In order that the sounds may be heard in the pilot-house or other distant part of the vessel, I inclose at the inner end of the IBSO-a nator a sound-transmitting device H, which may be an ordinary magneto-telephone connected through a metallic circuit to a similar receiver H, located in the pilot-house or other part of the vessel, or there may be several such receivers in the circuit placed in position for convenient use in various parts of the vessel. g I
The invention is intended to serve in indicating shoal water as the vessel approaches land, and when so used the sounder is put overboard and the number of fathoms to which it is to be submerged is reeled 0E. As long as the water equals or exceeds that depth the sounder travels through the water unimpeded and the resonator gives out acontinuous humming note, due to the passage of the fine wire through the water; but, as soon as the water becomes shallower the sounder contacts with the bottom either intermittently or continuously and the fact becomes immediately apparent by the cessation or' change in the resonator note. The invention also aids in enabling fishing vessels to locate above or near reefs, submerged wrecks, or other fishing-grounds. When thus used, I equip the sounder with one or more baited hooks J, attached to short lengths of line secured to a any convenient portion of the sounder and to the short portion B of the wire. The action of the sounder will indicate the depth and character of the bottom and the-presence of fish will be shown by their attack upon the ably at the rear, a1 electric lamp of the incandescent type, supplied with energy from a dynamo or battery through properly-insulated wires either connected temporarily to the lamp-terminals on the sounder or formed into asmalleablewiththesustaining-WireB. This modification is shown in Fig. 10. The illumination thus produced serves to attract fish to the vicinity of the vessel.
Other modifications may be made without departing from the invention. The form and proportions of the sounder may be varied. Other means for taking up the sustainingwire may be employed. The telephone may be omitted from the: resonator and the contact with the bottom indicated by the sound emitted by the resonator alone. For some uses the resonator may be dispensed with or its character varied. The addition of the baited hooks is intended for the special purpose before mentioned and for general service in indicating shoal water is not employed.
