' To the fastenings employed are common to the glass holder or sash ring and the dead light. That is to say, the same fastening devices are used to hold the glass light and dead light together in. the closed position, or alternatively the glass "'15 light only. Thus, when it is desired to close the dead light over the glass light, the fastenings must be released in order to enable the dead light to be closed. Similarly, when a closed dead light is to be opened, the fastenings must again be released so that the glass light remains unfastened during the opening operation. This is disadvamtageous, for in the event of a wave breaking over the ship during such operations, water would be admitted through the unfastened light.

The principal object of this invention is to enable the aforesaid disadvantage to be overcome in a very simple manner. According to this invention auxiliary devices are provided on the glass light or sash ring and such devices are so adapted and disposed as to be capable of co-operating with the fastening means even in the closed condition of the dead light. By this means, it is possible temporarily to use one or more of such auxiliary devices for the application of closing '35 pressure and the maintenance of water-tightness during the change-over from an open to a closed dead-light condition, or vice versa.

The invention is particularly applicable in those lights wherein the 'fastenings comprise in swing bolts carrying clip devices and nuts for tightening the clip devices. Fastenings of this character, in which the clip devices have an inclined surface to co-operate with an inclined surface on the sash ring or glass holder so as to ob- I tain a. direct or perpendicular fastening pressure, are described in the specification of British Patent No. 300,699 and such lastenings are very advantageously adapted for use in connection with these improvements.

In the application of these improvements to a side scuttle having fastenings of the character last referred to above, the auxiliary devices comprise bifurcated tooth-like projections formed on the periphery of the sash ring, or a part attached 58 thereto, at points corresponding with the positions of the swing bolts around the fixed framing. These tooth-like projections extend outwardly at an angle to'the general plane of the sash and present an inclined surface corresponding with the inclined surface of the fastening 5 clips.

One embodiment of the invention as applied to a light having fastenings of the aforesaid character is illustrated by way of example in the accompanying drawings in which:- 10

Figure l is an outside or front elevation of a scuttle-light with a dead light in position.

Figure 2 is a sectional view upon the line II-II of Figure 1 but to a somewhat larger scale,

showing the fastening means in two different con- 15 ditions, and

Figure 3 is a part sectional View similar to Figure 2 but showing the dead light removed and the fastening means in a third condition.

In general construction, the scuttle-light illus-go trated is similar to that forming the subject of the above mentioned British specification No. 300,699. As will be seen from Figure 1, the sash ring I of the scuttle light is hingedly mounted at 2 on the fixed framing 3, whilst the dead light 4 25 is similarly mounted at 5 so as to be closable over the light when required. The iastenings comprise four swing-bolts 6 pivotally mounted on the frame 3, clip devices I which, by themselves, are free to move along the bolts 6 but are prevented from so rotating thereon by screws 8 engaging grooves 9 in said bolts, and butterfly (or bow-handle) nuts H! to which the clip devices I are coupled by a groove and collar connection H in such manner that the said clip devices can be moved along 56 the bolts 6 by rotating the nuts iii. The clip devices l have an inclined surface I2 which, for se-. curing the scuttle light in the closed position, normally co-operates with a complementary inclined surface i3 upon an annular part of, or attached to to, the sash-ring I (Figure 3). In the construction illustrated, the surface i3 is formed upon a ring H which is secured tothe sash-ring i by screws [5 and serves also to secure the glass in said sash ring. i5 Auxiliary devices provided in accordance with the present improvements comprise bifurcated tooth-like projections 16 formed on the periphery of the ring It at points corresponding with the positions of some or, as illustrated, all of 50 the bolts 6 around the frame 3. Alternatively, such projections might be. provided upon the sash-ring i itself. These projections l6 extend outwardly at an angle to the general plane of the sash and present an inclined surface I! com- 56 plementary to the inclined surface I2 of the clip devices 1. The dead light 4 is provided with an annular rim or, as shown, with arcuate projections i8 forming segments of such a rim, said rim or projections being provided with an inclined surface l9 adapted for engagement by the clip devices 1. v

The manner of operation of the scuttle light is as follows: Assuming that the light is closed (Figure 3) and that it is desired to close and fasten the dead light 4, the nut in of a sash fastening is undone to release the clip device I from the surface i3 and the bolt 6 is swung outwardly. The clip device is then engaged with the corresponding tooth like projection l8 and the nut i0 tightenedfFigure 1, upper right-hand fastening and Figure 2 upper fastening). Where, as shown, there are four fastenings for the sash ring, preferably two opposite fastenings are loosened and re-fastened upon the projections H5 in this way. As soon as the tightness of the sash has been so ensured by engaging one or more of the clip devices with said projections IS, the clip devices of the other fastenings are released and swung out of the way to permit of the closure of the dead light, such closure being unobstructed by the fastenings on the projections l6. The dead light is then secured by the application and tightening of the aforesaid remainder of the fastenings directly upon the projections l8. Finally the. fastening or fastenings engaged with the auxiliary projection or projections i6 is or are then released therefrom and applied to and tightened upon the corresponding projections iii of the dead light. The bifurcations 20 in the projections I6 permit of the bolts 6 being swung in freely, not only to the position for securing the deadlight as shown at the bottom of Figure 2 and the left hand side of Figure 1 but also to that shown in Figure 3, when the dead light is absent.

For the opening or removal of a dead light, the reverse procedure is adopted: One or more of the fastenings is first released from the dead light and applied to the auxiliary projections l6 before the remaining fastenings are released to permit of the opening of the dead light. If the scuttle light is to be secured in the closed condition, the aforesaid remaining fastenings and then the fastening or fastenings first released are applied to the ring 14 as will be readily understood. In this way the sash ring I is never left altogether unfastened during the closing or opening of the dead light 4. r

If the scuttle light itself is to be opened, all the fastenings are swung right out (Figure 1, right hand lower fastening) so that the light can be opened without hindrance.

I claim:

1. In a ships light, the combination with a sash ring, a dead light and a plurality of fastening means common to said sash ring and dead light and comprising hinged bolts with clip devices and clip adjusting means thereon, and means on the sash ring and dead light adapted to'cooperate with said clip devices for holding said sash ring or sash ring and dead light closed,

of auxiliary devices in the form of tooth-like members projecting outwardly from the sash ring at points corresponding with the positions of some at least of the clip devices, said members being adapted for temporarily cooperating with one at least oi": the clip devices to hold the sash ring closed, independently of the remaining clip devices, whilst the dead light is being opened or closed.

2. In a ships light, the combination with a glass holder, dead light and a plurality of fastening means common to said glass holder and dead 5 light and comprising clip devices and hinged bolts having hand nuts thereon, the clip devices being formed each with an inclined surface to co-operate with surfaces on the glass holder and dead light and the inclinations being such that 10 the tightening of the clip devices by the hand nuts tends strongly to maintain the bolts in their upright position so as to ensure maintenance of perpendicular tightening pressure, of auxiliary devices in the form of bifurcated tooth-like pro- 14 jections' carried by the glass holder at points corresponding with the positions of some at least of the clip devices, said bifurcated projections being adapted for co-operating temporarily with one at least of said clip devices to hold the glass 9 holder closed, independently of the remaining clip devices, whilst the dead light is being opened a or closed.
