LANTERN.

Specification of Letters Patent No. 27,666, dated March 27, 1860.

To all whom it may concern:

Be it known that I, THOMAS E. DE FOREST, of New York city, in the State of New York, have invented a new and useful Method of Making Lanterns; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates particularly to round lanterns (as distinguished from square or other polygonally formed lanterns, in which each side is formed of a separate glass) and has for its object the construction of this kind of lantern, in such a manner that all its clifferent parts shall be securely and in a simple manner united together by means of their peculiar construction and combination, without the employment of any soldering or other cementing material and without riveting; but in such a manner, as to be capable of being readily detached from each other and reunited, while, when together, a more durable and desirable article is formed, than has heretofore been manufactured. And my invention has for a further object a more economical and desirable method of attaching and forming the handle of the lantern, and to these ends my invention consists in connecting the upper and lower ends of the vertical guard wires with the upper and lower metallic cases (or the top and base) of the. lantern by means of bending said ends of said wires into suitable shapes to interlock with annular securing bands or keying flange pieces, which are employed in connect-ion with the metallic top and bottom portions of the lantern, as will be hereinafter more fully explained. And my invention further consists in forming an eye in each of the vertical guard wires by bending, or forming it (around a mandrel or in any other suit-able way) for the reception of the encircling horizontal guard wire, whereby said encircling horizontal guard wire is retained in its proper relative position with the vertical guard wires without being soldered, or otherwise fastened to them. And my invention further consists in so arranging the encircling horizontal guard wire with the vertical guard wires that it shall be capable of sliding into the eyes of the former, and in connecting its ends by a thumb nut (coupling nut) whereby the circumference of the circle it forms may be increased or diminished for the purpose of bracing all the guard wires firmly in their relative positions with each other and with the other parts of the apparatus, as will be more fully eX- plained hereafter. And my invention further consists in connecting the handle to the cap or upper casing of the lantern by a single piece of wire, or its equivalent, so bent or formed as that its lower ends may be pressed together and passed down through the opening in the cap and will then distend and catch under said cap, as will be presently explained. And my invention consists finally in forming the handle of a strip of sheet metal bent into a circular form and its ends united by a screw or bolt, and in forming in the lower portion of said handle a depression for the reception of the connecting link, whereby the handle of the lantern is always retained in a position which renders it convenient to grasp with the hand.

To enable those skilled in the art to make and use my invention I will proceed to describe some of the modes in which I have practiced it, referring to the accompanying .drawings forming part of this specification.

Figure 1, represents an isometrical view of a lantern constructed after my invention. Fig. 2, represents a vertical section through the center of the same. Fig. 3, is a section similar to Fig. 2, of another modification of my invention. Fig. 3, is a partial veu tical section, showing the upper portion of another mode of applying my invention. Fig. 5, is a partial vertical section showing the upper portion of another mode of applying my invention and Fig. 6, is a vertical section through the center of the handle of the lantern.

In Figs. 1, and 2, A, F, F, represent the lower case or metallic portion of the lan tern, and c, g, h, the upper case.

B, is the glass.

(1, are the vertical guard wires and, 7), is the encircling or enclasping guard wire and, 0, its coupling nut, E, is the protector.

D, is the handle by which the apparatus is carried and, 0, is the connecting link by which the apparatus is attached or united to the handle D.

The bottom piece A may be cast of iron or made of sheet metal struck or spun up the annular piece F may be made of sheet metal, and is represented as being secured to the base A, by screw bolt, m, this piece F is of the proper diameter to accommodate the lower end of the glass, B, the lower head (5 of which rests on its upper edge which is turned over to form a rounded seat for it (as seen at a: Fig. 2). In the annular piece F near its lower edge are a number of holes, one for each vertical guard wire, a, and the lower ends of said guard wires a, are so formed that each runs down against the outer surface of the piece F to near its lower edge, and then bent at right angles enters one of the said holes in said piece, and the vertical guard wires, a, are retained in this position at their lower ends by an encircling band, F, which surrounds them, said band, F, having formed on its inner surface a series of depressions, Z, to accommodate the said guard wires, and at the same time lay flush against the outer surface of the piece F g, is a hat shaped metallic piece which is of suitable diameter to receive the upper end of the glass B, and the brim or lower flange of which rests on the upper head i of said glass the top of the piece, 9, is somewhat convex, and is open at its center, thus forming a deflector of the heat and combusted material which rises from the lamp: said piece, 9, like to F is provided with a series of holes to receive the upper and bent ends of the guard wires, a, which are retained by a surrounding band, h, formed with recesses, 2', to accommodate the wires, a, and with an upper flange which projects over the top edge of piece, 9, embracing between it and top edge of said piece the bottom flange of a cap C:the cap C, piece, g, and band, it, being all secured together by screw bolts, 1'. The protector, E, is of an inverted disk form, and has cut in its top a slot, sufliciently long to allow it to drop down on to the projecting parts, 0 of the link, 0. Said link or connecting piece is formed of a single piece of wire, bent into the shape illustrated, and its ends sprung into the holes in cap, C, and deflector cap, 9, (as seen at Fig. 2). The handle is formed of a sheet of strip metal bent round, and its two ends secured together, by a screw and nut, 61, (see Figs. 1 and 6) and its edges around that portion which is grasped by the hand (at, f,) turned over or secured to be more comfortably handled. Near where the two ends of the handle are united is formed a loop, 6, to accommodate the upper end of the link, 0.

In the modification illustrated at Fig. 3, the lower ends of the vertical guard wires, a, have one more bend than those seen in Figs. 1 and 2, (as seen at, (E, Fig. 3), and the glass retainer F 2 instead of having simple round holes to receive the guard-wires as in Figs. 1 and 2, has vertical slots 0 sufliciently long for the bent portions, (4*, of the guard wires to pass horizontally through, and said guard wires are retained or locked in their proper position by an annular flange plate G, the flange of which passes up between the bentportion, a, of said guard wires and the inner surface of the retainer F and is there secured to said piece F by screws or bolts, n, and in this modification of my invention, the upper portion of the lantern is differently formed and the upper ends of the guard wires diiferently secured, though, upon the same principle the upper retainer or glass cap g extends only a very short distance above the top of the glass and has not the guard wires coupled with it as in Figs. 1 and 2said guard wires being in this instance bent over the top edge of said cap 9 (and embracing between them and the said caps top edge, the foot flange of the top cap piece C) and then bent upward a short distance and retained by an encircling band or simple collars, which comes down on to the part, a of said wires and has notches cut on its internal circumference to accommodate or receive the bent up ends of said wires :the end of the guard wires, the cap, C, the cap piece, 9 and collars, 8, being all secured together by two or more small screws, 6 which pass through collar, .9, and foot flange of cap, 6, and into piece, g -the cap C here is illustrated as having a collar or shell C projecting inward from the top hole and the ends 0 of the connecting link, 0, as being caught under the lower edge of said collar, C the method forming the can, C, and attaching the clips of the connecting link 0 renders unnecessary theformation of any collar or shell on the deflecting top part of piece, 9 which I think an advantage over the method shown at Figs. 1 and 2.

At Fig. 4, is illustrated another mode of applying my invention. This figure represents only the upper portion of .the lantern, and shows the upper ends of the guard wires as bent somewhat in the form of a hook, and passing in through one hole, and out through another made in the cap, C, (after the fashion of a stick) and retained by the glass receiver and deflector, 9

In the modification illustrated at Fig. 5, the whole of the upper case or metallic portion of the lantern is formed of one single piece, C, which is so formed as to come down on the head of and embraces the upper end of the glass, B, as seen at g. It also is formed with the internal collar 9 to receive the connecting link and with an annular depression at g and a series of holes near its shoulder, 2'. The guard wires, a, are bent to conform to the depression, g, and then turned at right angles into the holes at, a immediately below the shoulder at 2' while at the depression 9 is wound around the whole (externally) fine wrapping wire, .2, which ties the guard wires, a, securely to the cap, C, they being prevented from changing their distance apart by means of their upper ends being held in the holes at, a

Fig. 6, illustrates particularly the formation of the handle, I), formed of sheet metal, and with a loop at, e, the part, i, is rolled over to make the upper portion of the handle more comfortable to grasp.

By forming the handle D of sheet metal as shown with a loop, 6, and its ends united by a screw bolt, said handle when released cannot drop entirely over to one side as the ordinary wire handles do, while at the same time it may be readily detached from the apparatus and is as economically made as those now in use and more durable. It has been customary in the construction of lanterns to attach the handles by means of a wire connecting link or piece, but in every instance a securing pin or key or other fastening has been employed to unite said link to the lantern. In my invention or improved lantern, it will be seen that said link is connected or united by means of its own peculiar shape; without the aid of any auxiliary piece, thus rendering the apparatus in this respect, more simple and less costly, while, at the same time, the link by being sprung into the annular shell C (as represented at Fig. 3) is retained more fully and rigidly than by the usual method of attaching it to the cap of the lantern. Previous to my invention the vertical guard wires have been soldered to the encircling guard wire, but in my improved apparatus the necessity of soldering or otherwise fastening the vertical guard wires to the encircling guard tire is rendered unnecessary wiile, at the same time they are more durably and eHect-ually braced by said encircling or horizontal guard wire by means of the eye (formed by simply bending the vertical guards) through which the horizontal guard passes as before explained. By forming the eyes a just large enough to admit the guard, Z), freely, said horizontal guard, b, may be distended or contracted as before mentioned by means of its double threaded coupling nut, 0, whereby the guards may be all braced up tightly together after the apparatus is put together. In lanterns heretofore manufactured the upper or lower ends, or both of the vertical guard-wires have been either soldered or riveted to the top and bottom metallic portion of the lantern, but in the construction of my improved apparatus, no soldering or other cementing nor any riveting process is employed, the ends of the guard wires themselves, being so bent or formed as that in connection with suitably constructed top and bottom metallic portions of the lantern (substantially as hereinbefore described) they may be readily and eifectually united to the upper and lower parts of the lantern by being keyed or otherwise locked to them. It will be observed that my invention in this feature of the apparatus is subject to many modifications, without departing from its spirit, since the gist of my invention consists in so making the different parts, that the whole may be formed without the aid of soldering cementing or riveting. It may be remarked in lieu of forming the eyes a in the vertical guards, they might be formed in the horizontal guard, but this mode I do not consider as practical as the one I have shown and described in this application.

Having described the nature of my invention and the manner in which it may be put into practice and not wishing to limit it to the precise details of construction shown and described, what I claim as new and desire to secure by Letters Patent is 1. Connecting the ends of the vertical guard wires, to the top and bottom portions of the lantern by bending them into such form as to interlock with said top and bottom parts and be secured thereto by encircling, or keying bands, or their equivalents substantially in the manner herein set forth. 2. I also claim so bending the vertical guard wires as to form in them eyes as described; in combination, with the encircling horizontal guard wire passing through the said eyes, the whole constructed and operating substantially as specified, for the purposes set forth.

3. I also claim arranging the encircling guard wire, Z), in such manner as to be capable of sliding circumferentially in its bearings in the vertical guards; in combination with the coupling nut, 0, so connected with said guard, b, that by turning it, the said guard wire may be distended, or contracted, substantially as set forth for the purposes described.

4. I also claim in combination with the top cap of the lantern and handle the connecting link, 0, so formed, of a single piece of wire, as to effectually connect or couple the lantern cap to the handle and properly support the protector, without the aid of any coupling pins or other auxiliary partas hereinbefore explained.

5. I also claim forming in the handle, when made of flat metal, a loop, 6, to operate in connection with the upper end of the link, 0, as specified for the purpose set forth.
