Fig. l? is a seetionof a flat paneot glass provided with a lens integral with said pane. Fig. 18 is a longitudinal section of a concave reflecting-glass body, having a closed front and provided with one or more electric lamp-receiving openings in its curved portion.
The nature of my invention is defined in the claims hereinafter presented.
In the drawings, A denotes the lantern, consisting of the tapering exterior ease ll, open at its larger end, the interior body C, also tapering, made of glass or of glass and metal combined, the socket l),conneeted to the said interior body, and the electric lamp 1* which enters into and is supported by said socket.
The construction shown in the first sheet of drawings and the several ways of connecting the socket l) to the interior body relate specially to a lantern for the use of divers in making submarine explorations, working upon sunken vessels, the, and also for use on vessels for the purpose of signaling, it being adapted for use in places where the lantern is liable to be wet. at any time,as it is so constructed that no moisture can get into the light to extinguish it, and in connecting the interior body C, which is usually made of molded glass, to the socket D it is essential that the connection shall be water-tight In l igs. L and the neck of the body C is shown as provided with a screw-thread (I on its exterior, on which is screwed a spun-metal screw-threaded sleeve F, the flanged end Z) of which bears againsta packing between it and the flange c on the said body The lamp-socket .l) in Fig. 2 is screwthrcaded on its exterior at (I to connect with the screw of said sleeve F, said socket being forced against packing at c and f, as shown.
In Fig. 4 the socket is smooth on its exterior and enters the neck of the body t, the flange g of the socket and the end I: of the sleeve being borne against the packings 71 and i, respectively, by the setting up of the sleeve F.
In Figs. 5' and 6 the neck of the body C is smooth, and at its junction with said body has an inwardly-projecting llange It. A spunmetal screwthreaded lining or sleeve (l, having prongs lat one end and a flange or. at the other end and cement applied to its exterior,
is introduced into said neclt. the shoulder o of said lining bears against one sitlcol' the flange it and the ends of th prongs ar turned so as to bear Jllitillsl th ot h.-r itltot' said tlang'c and securely conlin said lining within the ll(tl\', 'lhc lamp ocltct l is st-rcwlhica led on its c\'lct'iot' to connect to the sleeve,orliningytt. tHt-e l"i; itanil it in some cases I secure a spulrmctal screw-lhreadcd sleeve ll toa lamp-socket l having a smooth i exterior (see Fig. to and screw s:|ltl socltct, so mounted. into the lining 41.
in the forcg'oine'dc criptionand in the tie nres of the tll't't\\lllf "s rel'erred to the body is to be of molded gla the front o thcreot i being formed or provided either with or without a lens, (see l-ie's. and 4,) and when provided with a lens the crttcriorconical surface 11 of said body iscoatcd with a rettectint, material q, the latter being covered hya protect tve coating 1'. as in Fig. t said rellector throwing the light forward through the said front and the. lens; but when said front 1/ is unprovided with a lens the concave surface s of it; may be coatcd ith reflectingmaterial I, the latter covered on its exterior with a protective eoating' it, (see Fig. 11,) so as to spread the light upward and outward through the conical portion oi the bodyt. lit the lat ter case the glass body may be protected by enveloping it in a wire-ncttin in placeot' the exteriorcasing ll. A wironettingl is usually applied to the open end ot the casiu; l? to protect the front I), (see l ie's. l and 2,] and said casing is applied to the body t, so that it can be readily detached therefrom, the Springs 1' (see Figs. 2 and 2}) serving to illustrate one of the ways of connecting the hotly and the casing.
The casing 1; may also be provided with pockets u to receive weights K to overcome the buoyancy of the body (I To the easing 1; maybe applied a chamber in which the wires are to becoiled to prevent them from becoming: tangled, the outer end of the chamber after the wires are placed therein being closed by a (o\el,llle wires be ing led out of the chamber through an openi|1ftll9l(lll,2l5 represented in Figs. 12 and 14.
The lantern shown in Figs. 1:, 1 and it is adapted for general use where a powerful light is required and is especially useful in mines, tunnels, holds of vessels,&e.,or in any place where it is not liable to become wet. The glass body in this casemay be connected to the electric lamp in any suitable manner, it not being necessary that the connection shall be water-tight, and the outer conical surface of said body is coated with a reflecting material, the latter being covered by a protective coating, as shown in Fig. 10.
in nothing the rcllcctor ot the lantern ol' tnetal instead ol' glass, the trout end thereot may be closed by a convey, or .t'onc;t\'e,ora tlat plane of glass provided with a lcns, (see Figs. if], I and t7.) l. representin; a portion ola tnclal rcth-ctor; \lithc glass front orplane. and the lens integral therewith 'lheconvex snrl'at-e otthe trout o ol the glass body when ont\\'.ird.as shown in Fig. l l, maybe t'rhllc l with a rctlt-t-ting material. the latter covered with a protective coating, as explained. when said body is nnprovided with the outer casing It. The glass body maybe concave, provided with :I closed t'ront u and one or more openings r in its curved portion, as shown in l i lo, to receive and support "one or more electric lamps, the outer convex surface of said body being coated with a retlcet in e; material, the latter covered with protective coating, as hercinbtzt'ore described.
What i claim is-- l. in a lantern, a tapering body having; at its smaller enda tlange and screw-threadcd neck and at. the target." end a concave-convex front o, provided with a lens, all in one piece of glass, et'nnbined with a StftOW-hlllCfLdGtl metal sleeve, :1 socket, and an electric lamp,
5 said socket supporting the lamp andadapted to connect to said sleeve, essentially as shown and set forth, the tapering exterior of the body bcingeovered with a retlectin; material,
1 the latter covered with protective coating, as explained.
2. In a lantern, a tapering hotly t, having at its smaller end a [lance and scrmr-threaded neck and at its larger end a concave-convex t'ront o, all in one piece ot gla s, combined t with a serew-tln-eaded metal sleeve, a socket, l and an electric lamp, said socket supportingthe lamp and adapted to connect to said sleeve, the tapering exterior of the body being covered by a reflecting: material, the latter covered by a protective coating, as explained.
