Application filed t e-m 2a, 1899. Serial No. 707,154. (No many '1?) all whom it may concern- Be it known that I, MAR'Io Russo DASAR,

a subject of the King of Italy, and a resident of Genoa, Kingdom of Italy, have invented certain new and useful Telephouic Apparatus for Use on Vessels for Determining the Posi- .tion of Bodies'Moving Outside of Same,fof

which the following is a specification.

My inventiourelates to a t .elephonic apparo' ratus for use on vessels for determining the position of bodies moving outside of the same, so that. for instance, a vessel in a fog can ascertain the position ,of vessels moving near the same, and thus avoid collisions.

. The water in which a steam vessel travels is put in a vibratory condition owing to the cencussions imparted thereto by the pro pelling apparatus. According to my invention I provide an apparatus'for usein connection with ships to admit of such vibrations being collected and transmitted to a telephonic apparatus, this forming the subject of the present invention.

The apparatus consists ofa sound-receiver,

a direction-indicater, operating means for the same, a microphone, a battery,.and a tele phone.

The accompanying drawings represent the apparatus. 4

Figure lshows the sound-receiver in elevati on. Fig. 2 is'a plan view of the same. Fig. 3 is a section on line a; at, Fig. l. is an elevation-of the direction-indicator, its operating parts, the microphone, the battery, and the telephone. Fig. 5 is'a plan" View of the same. itudinal section through the center of the direction-indicator. j t

The sound-receiver R, Figs. 1, 2, and 3, is a metallic box of the shape of a semiprism, or

havingfaces at angles to each other, with a cpck r serving to' keep it closed when-the air has been exhausted. Each of the facesof the box is provided with a concave semispherical or. parabolic sound-collector A, which .may also be bf metal, the arrangement being such that the axial lines of all the sound-collectors converge toward the rear Wall of the-box, radiating from the same like the lines of a. fan.

5 In the center (If each collector a circular opening is provided, connected to a. metal tube a. All these meta] tubes aare bent down to- Fig. 4-.

Fig. 6 is an enlarged vertical lon-' Ward the bottom of the box in a curved liiie and finally terminate in' the cover of the box itself, whence, through the medium of the wan as many openings Having corresponding sockets as there are collectors in the receiver Rin the present case five. Y To these sockets are secured the tubes b, coming from the receiver R. The second cylinder n is located inside the first. and is adapted to'turu'on'end bearings in he vertical end walls of thecylinder m. T is second cylinder- 91. terminates at one side in a tubepand at the other side in a small shaft q. It is also provided with transmitting-tubes b, of flexible or suitable material, they are connected to the indicator.

This indicator D, Figs.

five openings in line with each other in the direction of its length, which correspond with the five openings of the cylinder at, so that the two'may coincide. In addition to these openings the cylinder n is furnished with live other openings g}, a'rrangedspirally upon its surface, so that at each sixth turn successively one of these openings will correspond with one of the live openings of the cylinder m. The small shaft q, which terminates in a crank w, is provided with, a bevel-wheel which is adapted to gear with another bevelwheel or with a toothed sector mounted on a spindle s. On this spindles a hand or index K iis fixed, which indicates upon the'graduated dial '0 on base 0 which of the openings of the cylinder m and cylinder n coincide; The tube 1) of the cylinder n'extends to the mi? crophone M,. which is in communication with the battery P andwitlr the telephone T.

With reference to Figs. .1 to .6 the operation is as follows: When thefive openings of cylinder 'n, which are arranged in a straight line, correspond with the-five openings of the cylinder m,the.interior of the cylinder 'n receives the sounds collected by all thefive collectors ofthe receiver R; Oirrqtating the cylinder 'n to-the extent of one-sixth of its circumference the coincidence of the first hole-of the cylinder m'withthe first hole a' of the cyl inder'n is obtained. Thus intothe interior-of the lasttcylinder, there will only pass the vibrations collected bythe first collector. On a continuing to turn the cylinder to the extent of another sixth of its circumference the second hole onlyofthecylind'er m will coincide with the second hole a';' of the cylinder n, and thus the vibrations collected by the second collector pass into the interiorot the'cyli-nder "n, and so on,so' that into the interior of the cylinder n there canarrive, andc'onsequently can-bethence transmitted to theniicrophone and to the-telephone-recei ver of'the telephone apparatus, either the vibrations collected by all thecollcctors together or those collected by each collector, according as is indicated by the index 4; upon the'dial o.

' It is evident tha'trthe base 0 may be so arranged on the ship that the direction of the [five collectorsof the collector correspond with the, positibns of the five divisionsof the dial 1;, so that when the operator holds the telephone tohis car while turning the. cylinder 'n'by means of the crank he will, owing to the ";.;.tion'. I 1

" 1 Having now particularly described and ascharacteristic vibrations he hears, gather from thegindex '21 the real direction in which the moving body or vessel he is listening for is at'the time, while the intensity of the vibrations will *be able to approximately indioate the distance. In Fig. 5 indicator D and pipe 1) term means for connecting the- ,collectors at will, separatel'yfo'r together, to

the electric telephone apparatus. Finally, it

. is evident that instead of one telephone two of them may be employed, but joined by a and thatdetails of the differentjarrangements shown in the drawings may be varied withoutdeparting from theessence of my invenband placed ripen the head of the operator,

certained-the nature of; my said inven tion and inwhat manner the same is to be performed,

I v; I declare that whatI claim tit-:-

1. In an apparatus of the character described the combination of a box adapted to be applied to a submerged part of a: ship, the box having several sides at different angles, concave collectors in several such sides, and a separate sonnd transmit-ting tube extending from eachcollector.

2."v The combination of submrfiged collectors A, sound-transmitting tubes 12 extending therefrom, and-a direction-indicator to-which tubes b connect, as and forth. j 3. In a telephonic apparatus for ships two concentric cylinders,the interior one of which for the purposes set is'provided with openings and can be rotated,

while the exterior one-is fixed and is provided with openings and tubes, which are connected to submerged collectors, substantially as and for the purpose described.

4. In a telephonic apparatus for. ships an inner and an outer cylinder each provided with a series of holes all of which can be in,

correspondence with each other at. the same time the in nor one having in addition another series of holes arranged so that-at each turnor partial turnof the inner cylinder one of .75 of the outer cylinder, substantiallyas and for thepurpose described. 7

5. The combination of ,a direction-indicating device, submerged collectors, tubes from them corresponds with one of the openings the collectors to said indicating. deviee,;a microphone, a pipe from the indicating device to said microphone, and altelephone' recei'ver.

.6; The combination of several submerged collectors, electric telephone apparatus at a distance from the collectors,and sound-transmitti'ng' tubes for connecting the collectors .with the electric telephone apparatus.

7; The combination of several submerged collectors,a'direction-indicating device,pipes connecting the several collectors to the indicating device there being a separate'tube for each-"collector, a dial, and an index-hand
