Application December 31, 1931 Serial No. 584,125

1 Claim.

the inventive idea will be apparent from the following specification. This application is a continuation in part of my application Ser. No. 334,679, entitled Combination marine lamps, filed January 24th,; 1929, and pertains more particularly to the improved construction illustrated in Figure 6, of the drawing and fully 'de scribed in the original specification. s Referring to the accompanying drawing:

Fig. 1 is a side elevation of a marine lamp;rep-

resenting one embodiment of my invention. Fig.

' 2 is a side elevation of same, in section, showing the illuminating means in position. Fig. 3 is a detail of the novel method of removablyretaining the illuminating means. v The lamp housing 6, it will be; understood, may

' be of any suitable type and construction employed 5 in the manufacture of marine lamps, A hollow,

cast body of cylindrical form is shown, by way of example. Fitted in an opening in the body is a suitable lens 7. The flange 8, serves as a base for the lamp by means of which it may be secured to the boat. The member 9, represents a suitable means for retaining the illuminating means in place in the body. The means 9, may

be a threaded plug as shown or any other suitable retaining means may be employed. Referring to Fig. 2, the threaded plug 9, is shown in place, in

a tapped boss formed in a part of the body shell,

which may be located where ever desired; Pass ing thru the opening 11, in the boss is a suitable electric lamp socket 12, provided with a base 13, ,0 and carrying an electric bulb 14. The-plug 9,

engages the base 13, therebyretaining the illuminating member in place,as shown. The opening 11, is suinciently large to permit the withdrawal of the complete lamp socket and electric bulb for replacing when required, from outside the lamp body.

Electricity is supplied to the lamp bulb by a flexible wire or cable .15, of such length as to permit removal of the lamp. Fig. 3, (Fig. 6 of the original application) is an enlarged detail view in which 6a, is a part of the lampbody' shell carrying the bossIlO. The socket base 13,

' is retained against the shoulder 16, by the retaining means 9, which may beof any suitable design. To aid'in removing the lamp and socket,

It is an object to the base is provided with a projection or handle 17,.and the plug 9, is provided with a screwslot 18.

Heretofore, marine lamps have been provided with a door in the body of the. lamp to afford access to the interior, or if no door is provided,

'it has been necessary toremovethe lamp from the boat to which it is fastened, thus affording access to theinterior thru the open bottom. By the means shown, asimple water-tight lamp may be constructed which may be secured in place I on the boat, and re-bulbing is easily accomplished in .the manner described' Elimination of the' door reduces the cost of construction and simplifies the construction. Moisture does not seep in and interfere with the electrical connections.

If desired, a gasket may be inserted betweenthe shoulder .16, and the base 13. An important feature'of this inventive idea. is that it permits a wide range of body designs, stream-line efiects and special shapes because of the absence of the usual door and the use instead thereof of the small and unique lamp retaining means shown and described. Inthe original application, it

will be noted that the lamp socket is carried by the means which is employed for securing it in place in the lamp 'body and that a swivel joint, for example, is employed to prevent twisting the electric supply wires when the retaining means is rotated while being secured in place. In the present invention there is no tendency to twist the wires be'causethe lamp'socket is independent of the securing means as shown.

I claim:

In combination, a marine lamp, a boss formed on its inner wall, an aperture formed thru said boss, a shoulder formed within said aperture at the inner face of saidboss, an electric lamp socket projecting inwardly thru said aperture and into the interior of the marine lamp, a base plate carried by said socket and engaged by the shoulder within the aperture, a threaded plug' screwed into the aperture for retaining the base plate in engagement with said shoulder, and means within the lamp body for supplying'electric current to the'lamp socket comprising a. flexible electric cable of sufficient length to permit the removal of the socket outwardly thru said aperture.
