Be it known that l, COSTANTINO Ftieazzi, fa. subject of the King of Italy, residing at ll'est Philadelphia, in the count-'y of Philadelphia and State of Pennsylvania, have iny vented certain new and useful Improvements in Safety Appliances for Ships, and do hereby declare the following to be. al full, Lclear, and exact description of the invention, such as will enable others skilled in the art f to which it appertains to make and use the same, reference being had to the accompany; .ing drawings, and to characters of reference marked thereon, which form a part of this specification.

. This invention has reference, generally, to safety devices for ships; and, the prese-nt 1nvention relates, more particularly to the applicatiou of suitably constructed pneumatic '20 safety appliances which are secured and are variously placed upon the deck of and within the body or hold of the ship, so that the said pneumatic safety appliances, in case the' 4ship is rendered helpless so as to be brought into a sinking condition, will act as buoys,

and will absolutely prevent the loss of the ship and life due to sinking. K

The present invention has for its principal object to provide a novel and simple safetyappliance which can be readily carried upon any ship, and which in the case of `a disastrous collision., or other cause which has placedthe ship in a sinking condition, can

.immediately be brought into use, either by .manualoperation or automatically, the pneu- A matic safety-a )pliance serving to buoy up `the sinking ship, and keeping the saine afloat.

The invention has for its further object to 40 provide a novel and simply constructed .safety-appliance, in the formof an air-filled Cask, barrel, or other suitable holder, and an .easily operated mechanism whereby the airreceiver and holder can be quickly lowered over the side ofthe ship, any number of such air-receivers and holders being adapted to be placed upon cach side of the ship, so as to properly buoy the ship and keep her afloat. V'()ther objects of his invention not at this time more.particularly enumerated will be i clearly understood from the following dctailed description of the said invention.

The invention is clearly illustrated in the aceonipaiiying drawings, in which Figure 1 is a side View of the hull or body I Specification of Letters Patent. l Application filed January G, 1910. Serial No- 536,755.

of a ship, said view showino' in elevation an f arrangement of pneumatic safety-appliances, and mechanism for lowering the same, t f

the' devices and.y parts illustrating one embodiment of the principles of the present inf ff; i

vention. Fig.- 2 is a. similar View of the devices and parts shown in said Fig.` 1, the ship' being represented in a. sinking condia. tion, and the pneumatic safety-appliance having been lowered, and shown floating-in e the manner of air-filled buo'ys upon the sea, so as to prevent the ship from sinkingentirely and becoming a total loss, aswell as preventing or at least minimizing the loss of life. Fig. 3 is a transverse vertical section, I0v made on an enlarged scale, of the hull of a ship, said view illustrating in. Aconnection therewith, and in end elevation, Vone arrangement of a. number of the safety-appliances and means for releasing the saine, to bring the several air-receivers and holders into their floating positions, both without and within the ship. Fig. 4 is an enlarged'detail view i said viewy showing a portionof the hull of the ship, with a part of its deck being rep- 8,0 i i resented in vertical section, and said view showin furthermore in elevation, one of the upper-t eck safety-appliances, in the form of an air-filled receptacle, tank, barrel or. cask, and the mechmism for retaining said safetyappliance in its normallyV inoperative position, and also for lowering the safety-.a pli-` ance upon the outer side of the hull or body of the vessel. Fig. 5 is a transverse vertical section of the parts shown in their normal v initial positions, said section being taken' on line 5 5 in said Fig. 4, looking in the direction of the arrow fr; and Fig. 6 1s a similar sectional representation taken on the same line, but showin the mechanism released to bring the airlled. receptacle, tank, barrel, or cask into its lowered position. Fig. 7 is a transverse vertical section taken .fon line 7-7 in Fig. 4, looking in the direcployed in all of the above'described views, 105' i to indicate corresponding parts. Referring now to the various figures of the drawings, the reference-diameter 1 mdicates the hull of any suitably constructed ship or sailing vessel, 2 is the upper deck; 11

3 and 4 are between l-decks, and 5 indicates the bottom of the vessel.

The novel safety-appliances which are to be used with the ship are inthe forni of pneunia tic floats, of which there may be any esired .numbeigfand which may be suitably disposed upon the upper deck and provided with mechanism to 'lower the floats down the outer sides of the ship; or, the said safet devices may also be placed within the bo y of the shi ,between the various between decks an in the several holds of thefship,

` or such two arrangements of the safety-devices may be combined, substantially as illusstrated more particularly .in Fig. 3 of the drawings, and as will be presently morefiilly described.

Referring now more particularly tov the l .Y safety devices which are placed upon ythe u per deck or outer portion ofthe ship, and

w ich are to be lowered down thel sides of the vessel, the reference-character 6 indicates however, that the Vsaid air-filled safety applianc may be of the usual casks o r barrels of wood, being' made of such strength so as to be useful for the purposes for which they are intended. Any number of such air-filled y t safety-appliances or receptacles 6 may be placed upon either side of the'sliip, each receptacle 6 being formed with a suitable opening for the admission of the air, and forcing it, preferably, under pressure to the air-receiving receptacle, said opening beingV tightly sealed by means of any suitably constructed sealing or closing device 7.

EachV cylindrical or Cask-shaped receptable 6 rests, in its normal initial position,

upon suitable supporting members c. elements 8, which are suitably secured by means of bolts`9, or other suitable fastening means to the upper portions of the sides of the ship, substantially as shown. Each supporting ineinberor element 8 is provided upon its upper edgeportion with an upwardly projecting rib 10, and an ofiset 11, which respectively provide ways and guides for the proper support of an air-filled safety-appliance or receptacle 6y between two of the supportiiio members or elements 8 'substantially as siown in Figs. 1 and 4 o the drawings. As will be seen from an inspection of Figs. 5, 6, and 7 of the drawings,

the said ways 11 incline downwardly toward the outer side of the ship, so that the airflled receptacle, when permitted to roll,

'will move in a direction toward and down the outer side of the ship, in the manner and for the purposes to be presently more fully described. In order to retain each airfilled ,receptacle in its normally inoperative position upon said ways 11 so as to prevent it from rollingoft' into the sea, there is suitably fastened to each receptacle 6, preferably by means of a suitably formed fastening means, as 12, the one end-portion of a flexible connection 13, such as a light chain,

the holding or retaining action of each flexin ectious`13 be disconnected fronrthe respective fastening devices 14, the said air-filled lered down the sides of the shi sf las to drawings, which are sufficient to prevent the upon dangerous reefs. andthe like.

As Shown, each pair of supporting'nieni- F ig. 4 of the drawings, and rotatably inount- 1G, provided at one end `with a crank or operating lever, as 17. Vsuitably. secured upon the said shaft or rod 16 are a parir of ratchetwheels 19. In operative engagement wheel 18 are the links of sprocket-chains or extending around and being in operative engagement with suitable Sprocket-wheels 21.

Vof these bearing-plates 23 are secured upon each side of the ship, by means of bolts or.

screws 9i, or other suitable fastenin at points upon the sides of the hull are sufficiently low, so that when the ship is in a sinking condition and the air-filled receptacles have been lowered, in the. manner to bepresentlv set forth, thel said lowered Each air-filled receptacle 6, in order to be properly lowered, is encircled, at the proper chains, as 25, each connection or chain 25 rope oi cable, which extends over a portion f of the rece tacle, substantially as shown in Figs. 3am 4 of the drawinds, and has its op iosite end-portion detachalily fastened to c eat 14, or other suitable fastening device, 1 liieh is secured upon the upper deck or. lier suitable part of the ship, as will ber clearly evident. Pulling normally against ,80 ble connection or tivhtening means 13 is the f tendency of the cy indrical or Cask-shaped receptacle 6 to rolloft the inclined ways 11 into the sea, and should such flexible con-y serve as floats, as indicated in Fig. 2 of the ed in the said bearing-portions 15 is a rod sprocket-wheels 1S, and also a pair of i other suitable flexible connections 20, said chains or connections extending downwardly upon the outer sides of the shipand csf receptacles G can be easily and quickly low- '95"' bers or elements 8 is made with a bearingf portion 15,iiidicated in dotted outline in with the teeth or Sprockets of said sprocket- These. s rocket-wheels 21 are secured n )on 'A P spindles 22, each of which is mounted in a bearing-plate, as 23. Any suitable number- ,1

,Normally in engagement with said. previously mentioned ratchet-wheels v1S) are springdogs or pawls, as 27,. whichA are' made in the forni of long arms or members which extend. in downward directions upon the in- Y ner side-portions of the. ship, andy are preferably connected by a bar or other suitable portion 28. Each spring-dog or pawl 2 has a suitably `formed bearing 29, by means ot which the said spring-dogs or pawls are oscillatorily'mounted upon and move with a rod which has its end-portions suitably 5 mounted between blocks 31. and 32, or other fastening and supporting means, secured in place uponthe inner faces of the sides of the ship by means of bolts or screws 33. That the upper free ends of' said spring-dogs or pawlszl'` are normally broughtinto operative engagement with` the` teeth of said ratchetwheels 19, suitably constructed displacementbetween the lower end -vportions of said spring-dogs or )awls andthe inner faces of the lsides ofthe s iip, thetendency of. these springs normally being to move Said lower end-portions in the directionofthe arrow y in Fig. 5 of the d awings, and the engaging portions of said spring-dogs or pawls in engagement with said ratchet-wheels 19, as will be clearly evilYhen it is desired to lower the said air-filled receptacles, the flexible connections 13 are loosened from said fastening devices 14 and the' rods or shafts 16 are made to rei volve in their respective bearingiortions by operating the cranks or levers ll.' The rotary movements of the sprocket-wheels 18, thus produced, will cause corresponding and proper movements of the sprocket-chains or tlexible connections 20, and the air-filled receptacles 6 being -flexibly connected with said. chains or connect-ions 20 by means of theend-portions or pieces 26 of the chains or connections 25, they will be caused to roll ott. the ways 11 of said supporting members or elements 8, and then moved downwardly upon the outer sides of the vessel, until brought. either partially or wholly beneath the surface of the sea, upon which they will float, as-will be clearly evident, and will be caused to hug the outer-sides of theshi 3, so as to act in the manner of independent floats 'or buoys which will positively prevent the ship from sinking. The engaging actions of the spring-dogs or wheels 19 is such, that. after the sprocketchains or conections and the an filled sa fety-devices have been lowered, they will -port-ionor piece tally as shown in the several figures of the springs, as 34, are securely' arranged against pawls with the ratchetwhereby, by turning the after the ship` has been again floated', or forl partially ralsmg said receptacles (3, so as to A bring them into their properly adjusted floating and buoymg relations to the sides of the damaged ship and the. lcvel'or` the sea.

kThis dog or patri-releasing mechanism con- 'sists, essentially, -in a rod 3G, the end- )ortions of which are rotatably mounted between' other fastening or` supporting means, the said rod 3G havinr said blocks 31 and 32, or

suitably connected therewith suitably forme( actuating lugs, as 37 which can be rotated against the backs o pawls 27, so as to disengage them. from their engagement with the rods or shafts 16 in the opposite directions, said rods or shafts are opposltely re` n volved, and the said air-illed receptacles (byy means ofthe intermediately placed sprocketchains or flexible connections 20 are suitably raised, as will-be clearlyevident. In order to revolvethe said rod or shaft 36, the lat'- ter has mounted thereon, upon one of end-portions. a lniter or beve -gear 38 which meshes with va miier or bevel-gear 39 mountsubstantially in the ed upon a spindle 40,

F 1g. 3 ot' the drawmanner represented in ings. lhis spindle is rotatably mounted in a bearing-portion 42 which is suitably secured to or forms a. part of a suitably constructed bracket or bearing-member 41, suitably secured by means of bolts or screws to the inner surface-portions Yof the ship, subextends upwardly through and above the upper deck 2, and upon its vided with -a hand-wheel 43, or other suit.- ahly constructed means for operating the spindle.

As shown more particularly in Figs. 4, 5 and 6 of the drawings, the saidspringdogs' or pawls herein-above mentioned extend into and through, and are movably arranged in openings 44 with which the upper deck 2 is provided, said openings 44 beine' bounded by metal lates 45, suitably secur upon the deck, an each plate 45 having an opening 46 which corresponds to and registers with the opening 44 in the deck. order to close the said registering openings 44 and it, and still not interfere with the movement of the spring-dog or pawl in said opening, I have affixed to the said springdog or pawl a plate, as 47,-wl-iichslides back and forth upon the said plate 45, during the movement of the spring-dog or pawl,

Each spindle 40y f "j and Aat not-imc. moves entirely oil' said opening 4(3,iis will he clearly evident. This plate ;"4T,therefore, serves as a closing means which i, iprevents dirt and water passing through t3'1; hev openings 44 and 46. 1 e I Referring now to Fig. 3 of the drawings, f if 1 itivill be secu, that an Aarrangement of air-V ililled safety-appliances may also be provided @between decks, these devices bein@r iny the 1b fprin ofvcylindrical or Cask-shape air-re` -`.;"ceiviiig rece itacles or containeis 48wliich fare dispose in suitable places upon the v f jdecks 3 and 4, and upon the bottom 5 of ythe ."ship. 'These receptacles 48 are of the flfsaine general construction of the receptacles 'y' 6. herein-above described, and said recepta- ,c les are encircled byesiiitable flexible con- .nections oi chains, as 49, and links 50, or "1' auxiliary iexible connections, are suitably f :'2 0,connectedwith said chains 49 and with suitlable eye-bolts 51, or other fastening devices, e ,substantiallyas shown in said Fig. 3.
