PORT LIGHT.
Application filed January 23, 1928. Serial No. 248,609.
This invention relates to a port light for vessels.
The object of the. invention is to provide a novel, simplified and attractive construction of port lightl which may be economically manufactured and in which` the cover member or door may be easily and conveniently opened and closed and locked and unlocked in its closed position. y
A further and more specific object 'of the invention is to provide a novel construction of port light iny which provision is made for maintaining the cover member or door yin different open positions in a novel and simple manner.
With these objects in view and such others as may hereinafter appear, the in,- vention consists in the port light and in the structures, arrangements and combinations` of parts hereinafter' described and particularly defined in the'claims aty the end of this specification. A
In the drawings illustrating the preferred embodiment of the invention, Figure l is a front elevation of the improved portflight; Fig. 2 is a part section and partl plan, the section being taken on line 2-2'of Fig. 1; Fig. 3 is a sectional detail on the liner 3-3 of Fig. 1; Fig. l is a detail to be referred to; and F ig. 5 is a sectional detail of the sleeve and operating handle forming a part of the port light.
Various constructions of port'lights have been heretofore proposed involving more or less complicated constructions with which the covers or doors ycould in practice be opened and closed7 only with difficulty. The present invention contemplates a port light of a simplified construction which may be manufactured at minimum cost and in which the cover member may be opened and closed and also locked and unlocked invits closed position with much more Aconvenience and ease than other prior constructions of port lights of which l am aware. lProvision is made for maintaining anl efcient watertight seal between the cover member and the body of the 'port light when the'cover member is closed and locked. Provision is also preferably made for securing the door or cover `member of the port lightin differn ent open positions in a novel yand simplified is formed with rarear portion 16 designed to lit into the hole l1 and also a forward portion 17 extending in front of the flange 111,'and the end surface 'of the forwardportion 17 of the'lhub is` preferably provided with an annular recess thereinl 'for the rev tenti'on ofa body 18 of resilient waterproof material such asrubber7 a strip of the latf ter] preferably being inset and cemented in the recess. n j
The port light is further provided with aV cover member 2O herein shownfas a cast ring provided with ears 22, which cooperate with ears '23 formed upon and projecting forwardly from ythe surface of the flange 14; to pivotally support the cover member 20 upon the flange by means of a pivot bolt 24: as shown. The cover member 20 is provided with a glass plate 26 secured within the cover 2O by a threaded retaining ring 28 as illustrated in Fig. `2. The interior of the cover ring 2O is also preferably 'provided witha vraised portion 30, whose opposite lsurfaces are tapered or beveled to enablefit tofengage the rubber ystrip 18` and to ber drawn tightly against thesame within the annular recess inthe endof the forward portion 17 of the hub 10, by the action of a locking device to be described, thereby providing a water tight seal for the port light.
Provision is made for holding the cover member 20 in'its closed position withk the y,raised kportion 30 kwithin they cover ring,
pressed against the rrubber strip 18,` as illustrated'in Fig. 2, to render the port light water tight, rand for this purpose as herein shown the interior of the cover member 20 is provided with a plurality of lugs which are spaced at invervals around the cover memberand at a suficient distance from one another to permit corresponding lugs 42 upon the periphery of the sleeve 35 to pass through said spaces when the cover member ismoved vinto a closed position. The adjacent'surfaces of the lugs 40, 42 are beveled to provide cooperating cam surfaces, one of which is shown at 44,'and which are arranged so that-when the sleeve 35 is rotated by means of an operating -handle 46 from a position in which the handle abuts a stop pin 48 in the flange 14, to a position such asis shown in full lines in Fig. 1, the corresponding pairsof lugs 40, 42 through the` cooperating cam surfaces 44 cause the cover member to be drawn toward the lflange 14 so that the port-ion 30 presses tightly against the rubber sealing ring, 18, as shown in Fig. 2-. The cooperating lugs 40, 42 upon the cover member and sleeve 35 respectively constitute locking members which effectively serve to retain or lock the. cover in its closed position until such time as the handle 46 is againv returned to a position abuttino' the stop pin 48.
- In order to hold the cover member 2O lof the portlight in diierent open positions,
provision is preferably made for locking the cover in various open positions, and as herein shown alocking pin 50 having an operating handle 52 is normally urged by a spring 53 within a fitting 54 screwed vinto a hole in one of lthe earsf23, into one of several holes 55 formed in the lower ear 22.
,In opening the port light the operator observed that the presen-t port light presents a vvery attractive appearance, adding considerably to the appearance of the stateroom or other portion of the vessel in which it may be located, and that the port lightdoor or cover may be opened or closed in a minimum time and with minimum eifort. The construction of the' port light is such that an etiicient water tight seal is provided when the cover or door is closed and locked, and in addition the relatively few parts entering into the design of the port light facilitates they economical .manufacture thereof.
