Letters Patent No. 107,165, dated September 6, 1870.I

*Mur- IMPROVEMENT IN SIDE LIGHTS FOR VESSELS.

The Schedule referred to in these Letters Patent and making part of the same I, WILLIAM DARLEY, of Chatham, in the county of Kent, (late foreinan of the Royal Dock-yard, Chatham, in the county of Kent,) have invented lm'- provenients in Ships IlluininatorsorScnttles, of which the following is a specification. i

rlhis invention relates to certain peculiar constructions aiid arrangements ot sliips illuininators or sciittles, applicable both to men-ollwar and to the inercantile navy, whereby facility of adjustment and of opening and closing are combined with economy and simplicity ot' construction.

The essential feature ot' this invention consists in making the dead-light and glass revolve on a pivot, in lieu of titting them with the ordinary hinges.

The dead-light and' glass are made in one frame, balancing each other, or nearly so, or the dead-light or glass, or both together, are made to turn independeiitly on a pivot, the said dead-light or glass, or both,

beingatall times parallel to the face of the sc'uttle or opening tov be covered.

The ti'anie surrounding the scut-tle or opening to be covered contains a packing of vulcanized India rubber, or other suitable material, and the t'raine ot' the dead-light and gia'ss, which inay be ot' iron, is provided with a raised annular projection, which is forced against the packing by the action of two or more screws or nuts, employed for securing the said dead-light orglass in their closed position.

' A helical spring is fitted into the pivot or axis on which the dead-light, or glass, or both turn, in order lthat, when the'saine are beingr opened, they shall be iorced out of contact with`the packing, ireparatory to turning them on their pivot.

A tightening-nut is also fitted onto the pivot oi axis, tor the purpose ot assisting the screw or nut, or screws or nuts,hereinbefore ret'erred to, in receiving 4the dead-light and glass, and also Afor tixing the saine when adjusted or turned on the pivot in any desired position, so as to lleave the opening either entirely or only partially closed. v

These improved seuttles or illuniinato'rs may be applied 0to the ports ot' ships7 cabins, to ships sides between thet'ranies, to water-tight or other bulkheads, and to tightin'g parts ot' iron ships; and,

1n order that my said invention 'nia-y be fully understood, I shall now .proceed more particularly to describe the saine, and for thatpurpose l shall i'eter to the several ligures on the annexed drawing, the saine letters of reference indicating corresponding parts in all the figures.

Figure 1, ot' my drawing, represents a front elevation, one modification of my improved ships illuniinator or scuttle, tully closed by thc glass.

Figure `2 is a vertical section of the same', taken along the line l 2in lig. l.

A represents a ships side, and

B is a tiauged ring fitted onto the mouth of the seattle.

C C' is a frame, hung on a centrally placed pin or pivot, D, the part G constituting the dead-light and the part C' the glass. This frame vC O'is balanced on its pivot or fulcrum D, so that it will oli'er the smallest possible resistance when being turned thereon. i.

The pivot or fulcrum D is securely fixed into the ships side and flange formed .on the ring B, and a helical or other spring, a, is interposedbetween the ,frame C C' and the said Iiaiige, for the purpose hereinafter explained.

A screw-tliread is cut on the outer end of the pivot, and an Ordinar f nut, captble ot' being turned by a spanner or wrench, or a buttertly-nnt, E, capable ot' being turned by hand, is screwed thereon, so as to press or bear against the siii-tace of' t-lie f i'aine O C.

An India-rubber packing-ring, b, is let into an annular groove made in the ring B, and corresponding projecting rings, c c', are formed on the inner faces otl the dead-light and glass-frame.

1 isa strong bracket tixed to the sides ot' ships, and to the flange ot' the ring B, and carrying a tightening-screw, G, provided with a suitable head or handle, H, for turning the saine.

lhe inner end ot' this screw presses or bears upon the edge ot' the dead-light or glass at a point dialnetric-ally opposite to the point where the nut lil on the pivot presses.

VVhe-n open, the fi'arnc C C hangs as shown in dotted lines in tig. 1, being balanced, but when the opening is to be closed, the glass or the dead-light, as the case may be, is turned up, so as to coincide with oi" cover the ring` B, and is then secured and made watertightby tighteningl the nut E on onel side and the screw G on the opposite side ofthe glass ordeaillight frame, thereby causing the projecting ring c or c' to be imbedded in the India-rubber packing.

A stop, d 11.', is formed on the riin ot the dead-light and glass, which bears against the side of the bracket F, when either the glass or dead-light is properly closed. 'f

On opening t-lie Scuttle the screw G and nut E are unscrew'ed slightly, so as to remove the l'ra-n'ie C C' t'roni contact with the India-rubber packing, the spring a, t'oreiigig outward the said frame when the pressure is reiiioved therefrom.

rlhe arrangement' shown at figs. 1 and 2 is adapted for the smaller sizes ot' scuttles, but when large sciittles, say up to twelve inches dianieter, are required, then 1 employ three or more tightening-screws or nuts, disposed so as to bear atseveral points all round the glass or dead-light frame.

Figure 3 represei'its n front elevation ot :t slight-ly modified nrrungonientfof' my -impi'oveiiieiits 'in ships7 seutilcs or illiiniiii ttors, :izlnpted tou twelve-inch sciittle, showing the gloss pn-i't-ly closed l.nid the (lend-light fully open.

Figure 4 is n vcrticztl seetion of' the sinne, sliowin` both `the ghtss rind dond-iight .fully closed.

A is the ships side. l

B, the thinged ring fitted onto thc month of the month of the seuttle.

C, the denddight, and

C', the-freine cnri'ying the glass.

In this ni'odificaition the (lend-light :ind glnss n-rc made sepnrnte, und nre opened und closed independcntly of' euch otlier,.liut11hey both turn upon one pivot oi; f'ulei'nni, l), which is eonimon tothe two. Or, if' l'n'eterred, such may have zi. scpzn'zite pivotor fulcruin ot' its own.

E is the tightening-nut on the pivot 1).

G is the tighteningserew in the iixcd brneltet F, stnnte opposite to the pivot D.

l I' tre lugs, i'oi'nied on the rim of thc dead-light .and gloss, for the reception ot' n loose screw which screws-into the socket. K, (shownin dotted lilies) when the dead-light. and gloss, or the glass only, is closed.

L Lnre notches, also formed on the. rims ot' the deuil-light :ind gloss, tor the purpose ot' engaging with the s tntionnry stud or pin M.

This stud or pin is screwed :it its outer end und provided with n tightening-nut, N, enpzible of'- being screwed down onto thedend-light, or onto the traine ot' thcglnss, :is required.v

b b nre. Iiidin-rublu-r packing-rings, let into grooves mnde respectively in the. fixed ring B, :ind in the f'ruine C ot' the glass; :ind

c o' :ire lprojecting,` rings formed respeetivcly upon t'lie faices ot' the' glnssd'rnnie n.nd desd-light, for the purpose of' insuring u pert'ectly water-tight joint when the shuttle is closed Int-uses where :L glass only is fitted to the senttle, then the Indie-rubber ring b' will he dispensed with.

'lwo helienl, or other openings, :1re employed, the one being interposed between the f'i'ziine ot' the gloss :lnd'the tixed rinr B or side ot' the ship, neeiuding ns the flange oi' the ring B is inside or outside the ship, while the other spring;I is interposed between the f'i'nn'ie of the glnss und the (lend-light. The object of these. springs is to force the gloss or (lend-light clem' ot' its packing prepnraitory to its being opened, und to yield sittliciently to zillow of' these pnrts being screwed up tight n ninst the. packing ngnin, when requisite.

In this modification it will be seen thntthere nre f`onr benring points round the glass or dead-light for the tightening-nuts or screws to beznor press against, whereby perfect security und tightness nre obtnincd.

Iy planing: the flange oi' the fixed ring li outside the ship, :i lnrgei' scuttlc muy be employed, und where the spare or interval between the sliips i'i'zimes is liniited, i' will be formed ndvzintngeons to multe, the gloss und dend-light sepnrzite, :rs shown in tig-s. 3 und 4, by 'reason ot' their then occupying n snnillcr space.

Should it, however, be preferred to in'nke. the dendlight znid glass in one frnine, then the-'ring B should bc mnde sufficiently deep to ndniit of' the Atraine C C working in t'ront ot' or over the4 angle-iron f'rnines of the ship, but within the suri'nce. ot' t-he wood lininior on the ships side.

d' is n buffer or stop of indio-rubber, lo check the full ot' the lend-light or gloss.

Figure 5 is a section taken throngli the fulcrnni, pin, or pivot, of' another modification, based npdn the principles hereinl'ieire described.

rlhe mnin alteration in this modifient-ion is the substitntioii ot' marginal screws on the rims of' the dea-dlight and glass, for securing:r and tightening them in their places, for the nuts und screws pressing upon the rims of the dead-lightvand glass in the previouslydescribed zn'rzingeinents.'

A is the ships side.

B, the fixed ring.

C C', the. dead-light and glass.

Y I), the pin or pivot'lupon which bot-h turn.

ll, the tightening-nut on the pivot.

a to :ire the helical springs for easing ott' the dendlight nnd'glatss as they are unscrewed.

,Lhe glass-trame C' screws, by means of` a. marginal screw :it e, into the tixed ring B b,'and is surrounded by n ring, C, in which it turns freely when being screwed or nnscrewed, it being held in snclr-ring by a pin and circumferential groove.

rlhis ring C" pivots on the pin D, and is forced ontwnrd us the glass is unsci'ewed by the pressure of the spring a.

f f nre two recesses or holes made in the glass-rim, for the enti-anice. ot' n key for nnscrewing the saune.

rlhe piece. ot' glass itself is secured in its frame by :i sinnll ring, y, Vheld in position against a. shoulder on the rini, so :is not to strain the glass, by means of snizill screws.
