DEVICE FOR LOGA'l'lNC? SUNKEN ARTICLES SPECIFICATION forming part of Letters Patent No. 637,147, dated November 14, 18.99. Appnmion inea my 5,1899. seria No. 715,739. (No man To all whom, it may concern/.-

Be it known that I, TnonAs JOSEPH MORI- ARTY, a citizen of the United States, residing at Newport,i n the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Devices for Locating Sunken Articles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable oth- Io ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forrn a part of this speciiication.

This invention relates to new and useful improvements for locating sunken articles; and it consists in the provision-oi a buoy which is housed in a suitable receptacle and anchored to the article which is sunken by means zo of a cord which has one end secured to the casing, the other end to the b'uoy, and wound about the latter, means being provided whereby said buoy may be released from its'casing, which is carried by the sunken article, means being provided for automatically releasing the cover of the casing by hydrostatic pressure while under water in conjunction with clock mechanism, which may be set so as to allow retaining-bolts to be withdrawn at a 3o predetermined time.

More specifically the present invention consists in' the provision of a device for indicat ing the location of slinken articles, such as torpedoes, firearms of various kinds, lobsterpots, fish-cars, die., and consists in confining within a casing a buoy, about which is reeled a cord, which cord is anchored to the casing, the latter being of such size as to be readily fitted into .the article the location of which 4o is to be indicated, said casing containing a clockwork which is designed to withdraw a retaining-bolt, and a spring-actuated piston which has connection with a second releasingbolt, whereby the pressure 'of water upon the piston-head will cause the second bolt to withdraw from its engaging relation with the cover of the'casing, whereby the buoy will be'allowed to leave the casing and float to the surface o f the water, thus forming an indication 5o of the sunken article.

To these ends and to such others as the invention maypert-ain thesame consists,furth`er, in the novel construction, arrangement, and adaptation of parts, as will be hereinafter more fullydescribed and then specifically dened in the appended claims. l

My invention is clearly illustrated inthe accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings 6o similar letters of reference indicate like parts throughout the several views, in which- Figure l is a sectional view through the casing and the buoys and piston contained therein. Fig. 2 is an end view of the casing, show- 65 ing the cover removed. Fig. 3 is a sectional view through a portion of the stock of a gun, allowing the device as applied to the stock.

' Reference now being had to the details of the drawings by letter, A designates the cas- 7o ing containing my improved mechanism, which may be made of any suitable shape for the purpose for-which it may be designed, and in the present instance I have shown the casing as cylindrical andadapted to beiittcd 7 5 within an automobile torpedoY or any other article the location of which isdesired tobe determined when sunken. This casing con- Atain's the buoy B, about which is reeled a rope C, one end of which is connected to the cas- 8o ing, as at C', and its other end to the buoy, as at C2. Said casing has a cover D, which is hinged at D to the casing and is provided with two catches D2 and DS, which are engaged by the spring-actuated bolts E and F. The bolt E has a series of rack-teeth E at one end, which teeth are designed to mesh with the teeth g of the pinion-wheel G, which is mounted on the shaft G' of the clockwork mechanism, which is contained within the 9o compartment 1I of the casing. This clcckwork mechanism is ot' the ordinary construct-ion common in alarm mechanisms and so arranged that-'it may be set to go olli at any 'stated time and cause the bolt E to be disen- 95 gaged from the notch D2. As no novelty is claimed for this clock mechanism, no detailed illustration or further description of this mechanism is deemed necessary.

On one side of the casing is a cylinder K, roc in which works a pistou J, which is acted upon by a spring L in the lower part of said cylinder, thel tension of which spring serves to keep the piston'J normally at its highest limit, but allowing -the 'same'to be depressed under tension of the spring when the device is sunken and acted u'pongby the, pressure of-v the water bearing upon the upper face of said piston. Mounted in said cylinder' and connected to the piston -is-therod'M, the upper end of which is connectedat n to the segment N, which has a series ofteetl'i'N, which are adapted to mesh with the teeth F on the spring-actuated" bolt'Ffas-'thzepiston is depressed,",th1us :causing bolt to disengage l witlrithe notch D3,';with which it norm ally engages'when -tlreiappalratusis in shape for use.
