HYDROSCOPE.

Specification of Letters Patent.

Patented April 9, 1907.

Application l September 23. 1903. Serial N o. 174,338-

have applied for Letters Patent of Italy,

July 28, 1903,) of which the following is a specification.

This invention has for its object a hydroscope for exploring and hotographing the bottom of the sea from t e surface and recoveringsubmerged objects.

I am aware that telescopes already exist for, exploring the bottom of the sea; but such apparatus as heretofore constructed are not ages of the objects lying on the bottom of the sea. 'I have therefore constructed a hydrosection and a plan view, respectively of a third 4 4o scope of which the following is a clear and complete descrptionand which is shown in the annexed drawings, of whicl Figural shows the hydroscope formin the object of the invention, partly 1n vertica section, attached to a floating raft or buoy. Fig. 2 shows the apparatus in its 'osition of resti. e., in a condition adapte for being moved from one spot to another or for being towed. Fig.3 is a vertical section of one form of the objective. Fig. 3 is a horizontal sectional view on line 3 3 of Fig. 3. Fig. 4 is a verticalsection of another form 01 the obj ective Fig. 5 is a vertical section of the eyepiece provided with a single telescope. Fig. 6 is a vertical section of the hydroscope arranged upon a vessel, extending and telescoping being obtained by an electrically-worked rack-and-pinion device. Figs. 7 and 8 are a form of the objective. Fig. 9 is a vertical sec tion of a fourth modification of the objective. The hydroscop e may be fixed to a ship or be independent-that is to say, adapted to a floating raft or buoy, on which in this case are installed all the appliances necessary for its working. i j

4 Referring now to Fig. 1 of the drawings, the hydroscope may be formed of one or more tubes 1, suitably connected one to the other, so as to prevent ingress of water at the joints. The hydroscope isl'urtziermore provided at its lower portion with an objective 3. It is obvious that the. hydroscope, either axially motor 15;

case provided with the necessary devices for extenslon toward the ob ects to be surveyed and for telescoping. When the hydroscope is arranged on a buoy 4, in which case it is always arranged axially, Figs. 1 and 5, its ascent and descent is effected by means of a capstan 12 or equivalent appliance on which is wound a cable or chain 9, the other end of whichis fixed and supported on an auxiliary buoy-'10.

By unwinding the chain 9 from the capstan 12, so as to leave said chain slack, as seen in Fig. 1, the device will assume a vertical position, which is the. operative position; but when it, is desired to incline the device for any purpose, as for towing, the capstan is turned so as to wind 11 .the chain, and this will or course. cause the clined position, as seen in Fig. 2. In the said figure, 1 3 is a support placed on the lower extremityof the last or extreme element on the pulley on which glides the said chain.

, The eyepiece 2 maybe provided with lenses, as usual, or with a telescope, as shown in Figs. 5, 6.

The objective 3 is provided with simple lenses or with condensers 5, having two or more lenses, and with a reflector 6, controlled by rods 7., communicating with the platform of the buoy 4 by means of a chain or cable, with the aid of which it may be caused to ap. roach or move away from the condenser.- t also may be' provided with powerful lighting appliances with reflectors.

All the manipulations of the capstan, &c., may be effected by hand or by an electric The latter may also work screwpropellers 14 and 14 for movements of translation, &c., of the hydroscope, Fig. 2. To

incline the apparatus as shown in Fig. 2, it 9 is su'l'licient to turn the capstan 12, Fig. 1-, in the direction of the arrow. The cable in winding itself up will be more and more tightened, and as the buoy 10 does not cede the apparatus will be inclined, owing to the action of support 13 and pulley 8.

-In the form of objective shown at Fig. 3 the condensers 3 are arranged radially to tube 1, which in its lower part is enlarged, so as to receive the polyedric reflecting-conus 2, composed of four or more faces, adapted to reflect on the eyepiece the images takenup by the difl'erent condensers. In the said arranged on a buoy, Figs. 1, 2, and orlfigure the condensers 3 are four, arranged 5 placed on a vessel, Fig. 6, must be in every 1 symmetrically in a horirontal plan; but it is evice to assume an inber of which may vary according to the cir-- cumstances.

6 is the movable polyedric reflecting-conus, located at the exterior of\ the tube, .but axially with the same. the movable rods in communication by ropes or cables with the operator, who thus is capable of raising and lowering the reflectingconus, so as to bring it at the necessary focal distance from the condenser. 8 are the bars of the protectioncage. -9 are the electric lamps; 10*, the corresponding reflectors.

In the form of the eyepiece of the hydroscope arranged on a buoy, Fig. 5 I IS the tube. 2 is the flange of'connection with the elements. 3 is the telescope proper or any equivalent instrument to approach the objects reflected by the cone. In the said figure the telescope is arranged concentrically to the tube of the objective. As, however, the number of telescopes maybe two or more, it is understood that whatever may be their number they will always be arranged eccentrically to the axis and in such a position that the operator will be able to look simultaneously in two of them.

Fig. 6 represents another form of thehydroscope, located in the interior of a vessel to surve vertically the objects placed below the vesse In this modification when the hydroscope is in'its position of rest the objective occupies a kind of chamber 6 in the hull of the vessel, closed. by a rack-actioned door 7 which glides between air-tight walls 8". The hydrosco e, Fig. 6,'complrises two tubes telescoping t e ne within t e other. The outer or stationary one, 2?, bears the telescope eyepiece 10, while the movable one, '1 bears the objective and is provided with a rack 5 0perated by a pinion 4, keyed, which pinion may be rotated by any suitable means, as an electric motor, for instance. Suppose it is desired to lower the hydroscope in order to a proach it to the objects to'be examined. T e sliding door 7 is opened, and then the electric motor 3 is started, which, meshing by a pinion with the rack 5, causes the apparatus to descend, while turning the'motor 7 are in the opposite direction the apparatus, obviously, will be shortened or telescoped.

Figs. 7 and 8 show another constructional form of the objective. The latter consists of a polyedric reflecting-cone placed in the interior of a tube enlarged in its lower portion and is surrounded b a crown of semiconvex lenses independent om each other, each of which corresponds toone face of the said cone. Each lens is protected bv a crystal disk tightly fixed on the tube. In the'said fi ures, a is the objective proper; b, the polyedric reflecting-cone; c, a series of semic0n vex or bulls-eye lenses arranged radially and cachcorresponding to oneof the faces of the said' reflecting-cone. d are the protectingcrystals, forming a tight closure. e is the bottom'of the chamber. 7c is the magnifying-lens.

Fig. 9 shows another simplified constructional form' of the objective. In this figure, g is the tube; f, the magnifying-lens; i, the sem'iconvex or bulls-eye lens, and h the crystal ring protecting the lens.-

Having now particularly described my said invention and the manner in which the same is to be performed, I claim- 1. In an apparatus of the character'described, the combination with a bodyportion composed of tubular sections secured together, of an eyepiece at one end of the body portion, an objective at the opposite end of the body portion, a floatable body from which the tubular body portion is suspended, a capstan carried by said floatable body, a reflector arranged below the objective, a' second fioatable body and a chain connecting the latter and the capstan.

2. In an apparatus of the character described, the combination with a body portion composed of tubular sections secured together, of an eyepiece atone end of the body portion, an objective at the oppositeend of the body portion, a floatable body from which the tubular bodyportion is suspended, a reflector arranged below the objective, a second floatable body, a capstan on the first floatable body, a chain connected with said capstan and the said second floatable body, an arm 13 on the tubular body portion, and a pulley on said arm, around which pulley the chain passes.

In witness whereof I have hereunto set my signature in the presence of two witnesses.
