` SPECIFICATION forming part of Letters Patent No. 308,708, dated December 2, 188 4.

Application filed November 10. 1853.

T 0 all whom t may concern:

Be it known that I, DUNCAN SINCLAIR, of Vai-Nui Oinata, ITellington, New Zealand, have invented a new and useful Improvement in Marine-Record Preservcrs, ot' which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in whichssiinilar letters of reference indictte corresponding parts in all the figures.

Figure 1 is a side elevation ot' my improvement. Fig. 2 is a sectional side elevation of the saine, taken through the line x m, Fig. l. Fig. 3 is a sectional plan view of the saine, taken through the line y y, Fig. 2.

The object of this invention is to provide a convenient and reliable means for preserving the records of ships wrecked or otherwise lost at sea.

The invention consists in a marine-record preservar constructedwith outer and inner cases connected at their open lower ends by an ann'ular plate,and provided with a cork ling and a separable tube attached at its lower end to a cap-plate screwing into the annular bottom plate, and provided at its upperend with a screw-cap. The preserver is protected from accidental injury by rubber or rubbercloth sheathing plates applied to its outer case, and is made more buoyant, and is i'ur` ther protected from accidental injury by cork blocks strung upon a wire and secured to the outer case and the sheathing-platesby eyerivets, as will be hereinafter fully described.

A represents a case,1nade of thin sheet-copper. The top of the case A is made convex, dome-shaped, or semisphcrical,and the body of the said case is tapered downward,as shown in Figs. l and 2. The convexed top of the case A is connected with the body of the said case bya seam, B. The body ofthe case A is strengthened against injury by sheathing plates D, o1" rubber or rubber cloth, tit-ted to the said case and having their edges bent outward and sewed to each other by wire, or secured by other suitable means. rIhe edge of the case A is soldered or otherwise secured air and water tight to an annular plate, E, to the inner side of which is soldered or other- Wise secured air and water tight the open lower end of the close-topped tubular case F.

Renewed July 2', 1854. (No model.)

By this construction an air and water tight space is formed between the cases A F,which space is designed to be lled when the preserver is being niade with cork, R', cut into such a shape as to iit snuglyinto the said space, andthus make the preserver very buoyant, so that the preserver will ioat evtn should the case A be injured or evenV perforated. In the inner edge of the annular plate E is formed a screw-thread, into which fits the screw-thread formed in the outer surface ot' the tubular iiange` G-, formed upon the' capplate H. A flange "upon the cap-plate H over` laps the outer side of the annular plate E, and has a packing, I, of leather or other suitable material, interposed between it and the said annular plate E, so as to make the joint between tlie said plates H E air and water tight.

To the upper edge of the annular flange G is soldered or otherwise secured air and wa` ter tight-the lower end of atubular ease, J, the open upper end of which is closed by ascrewcap, K, the joint being made ain and water tight by a packing-plate, Il, laid upon the upper end of the tube J and upon which the cap K is screwed down.

In the bottom of the tubular case J is placed a cork plate, llL-for the roll of records to rest upon.

Around the outside ofthe preserver is placed a ring of corks, N, strung upon a wire or chain, O, which passes through the `eyes of eyerivets l?, secured to the said preserver at the water-line, so as to make the preserver more buoyant and further protect itfrom accidental injury.

Upon the bottoni ofthe cap-plate His formed a flange or keel, Q, which has a hole formed through it to receive a lever for screwing the capplate H off and on.

The preserver is designed to have a roll of records giving the naine of the vessel, the termini of the intended voyage, the names of the officers and crew, and any other desired information, and an ink-pencil placed in the inner detachable case, J, so that in case of accident to the vessel the person having the preserver in charge can take out the record-roll, write in it a brief account of the accident, reinsert the record, and throw the preserver overboard, with the expectation that it will IOO bc picked up by sonic vessel or driven ashore by the wind and waves, to give an account of the fate of the vessel and crew in case no one should be saved.

The preserver should be kept upon the deck of the vessel, and secured in such a manner that it cannot become detached by the rolling of the vessel, but will become detached and float should the vessel suddenly sink before the person in charge of the preserver can make an entry and throw the said preserver overboard.

The top of the preserver is designed to be coated with luminous paint, so that the preserver,when floating in the sea,wi1l be visibleA by night, and the painted top of the preserver is designed to be covered and protected by a plate, S, of glass, horn, or other transparent substance, as indicated by dotted lines in Fig. l, the edge of which is secured by atlange, C, soldered or otherwise secured to the said top.

The brass plates H and K are designed to havelegibly engraved upon them the name of the vessel and of the country or port to which the said vessel belongs, and also the date of the building or launching of the said vessel.

Having thus described my invention, I claim as new and desire to secure by Letters Patentm l. -A marine-record preservcr constructed substantially as herein shown and described, and consisting` of the outer and inner cases, A. F, connected at their' lower open ends by an annular plate, E, and provided with a cork filling, R, and the separable tube J, attached at its lower end to a cap-plate, H, screwing into the annular plate E, and provided at its upper end with a screw-cap, K, as set forth.

2. In a marine-record preserver, the combination, with the top of the case A, having a coat of luminous paint, of the transparent covering S and the iiange C, substantially as herein shown and described.

3. In a marine-record preserver, the combination, with the outer case, A, and the sheathing-plates D, of the cork blocks N, the conmeeting-wire O, and the eye-rivets P, substantially as herein shown and described,whereby the preserver is made more buoyant and is protected from accidental blows, as set forth.
