Bnrrs, a citizen 'of the United States, residing at New York, borough of Brooklyn, in the county of vKings and State of New York, have in-l vented a newand useful Improvement in vTubular Lanterns, of which the following to increase the strength, stiii'ness and dura-V bility of the'lante'rn. Inthe accompanying drawings; Figure 1 is a side elevation of a tubular lantern provided with my improvements.l Fig. 2 is a partly sectional elevation at `rig/ht angles to Fig. 1. Fig. 3 is a fragmentary vertical section, on an enlarged lscale, ofthe upper portion of one of the tubes and connecting parts, 4-4, Fig. 3. 5 is a sectional perspective view of the lower portion of one of the tubes and connecting parts. Fig. 6 is a perspective view of one of the bail ears. Like characters of reference refer to like 'parts in the several figures. A represents the oilpot and B the body .hoop or lower ring of the lantern frame intowhich the oil pot inserted from below and to which the'oil' pot/is ydetachaloly secured by a spring catch bof any suitable con struction. C represents the air tubes which are secured' at their lower ends to the bodyhoop and whichiextend upwardly to -about the level f the upper 'guard ring D. E represents the lantern top which is movably connected to the upper guard ring, preferably; in fthe usual manner by alhinge 10 at therear side and'acatch 11 lat the front lside of the guard, so that the globe F can be introduced into the guard fromabove. l G represents themetallic chimney within 4 a Veitialtransverse section in line the lantern top which bears upon the globe and holds the latter on the body hoop. The hinged lantern top E comprises a cy'- lindrical outer wall 12 forming the upperannular air chamber, a horizontal flange or refiector 13arranged below this wall and cxtending outwardly beyond the same and beyond the air tubes and the `upper guard ring, and elbows 14- which extend from the cylindrical wall 12 to the horizontal iiange 13. The' cylindrical wall 12 of the upper air chamber has its side openings 15, through which the air passes from this chamber into the tubes, provided with outwardly projecting short collars 16, -which 'enter the upper ends of the elbows 14. The lower ends of these elbows are seated in ferrules or socket piecesl which are arranged in openings formed in the horizontal flange 13 above the tubes. The upper portion of each ferrnle is larger in dian'letcrilmn the 'lower portion, forming a. horizontal shoul` der by which the ferrule rests on the hori- Azontal flange 13. 'lhe lower contracted portion lof each ferrule extends downwardly through the opening in the /tlange and regis` ters with the open upper end of the corresponding air tube into which it extends, when thelantern top is closed and locked to the guard. Each yelbow 14 is securely held in place by the collar lfand the ferrule 17, in assembling the parts of lthe lantern top and will remain in its proper position without requiring to be tacked by solder. After the parts have been so assembled the top is dipped in molten tin -in the usual way, whereby all of the parts are periminently and. firmly secured together. The parts of the lantern top are so assembled and secured together in a Very simple and inexpensive manner .and the connections between the elbows, the an' chamber and the horizontal vclosed upon the guard the ferrules, which form downward extensions of the elbows, 4project into the open upper ends of the tubes and produce a'sutliciently tight joint l between the latter and the elbows to pre- -ve-nt external air currents froml exhausting the air from the upper ends of the tubes or' otherwise interfering with the air currents. The rigid lantern" frame comprises the body hoop B, the air'tubes, the top guard ldown to the bottom ring ll. and an interme- `projertinpY short collar lll which projects members Vl are preferably seeured to the i a imn ring,r D, lthe bottom guard ring H, upright main guard wires or members` l which extend from the top ringl? to the bottom guard ring H and arevseenred at the waist to the body hoop B, Supplemental upright Huard wires or members K which extend troni the lower portions otI the air tubes t i l diate guard ring L conne ting); the main upright `guard members between the body hoop and the top ruig, opposite the bulge oit the globe. The upright. `guard members and rings may be of w1re, as shown, or ot any other suitable iiiatei'ial. .lll represents the bail ears which are sleeured to the; outer sides ot the tubes, near the upper ends thereo', and comprise an attaohingl plate 1S and an ear proper 19, both stamped in one piece from a blank ot sheet metal. The attaching plate isreurred to lie snugly against the tube and is provided at 'its lower end with a rearwardly otlzsetV lip i2() which is inserted into the tube through a slit. in the outer side thereof. rlhc upper corners otx the attaching plate are each pro- `vided with a perforation 9.1- and the tube provided with a eoineidentv perforation, i t.lirou1h'both of which the. hooked end port tion 22 oil' the top guard ringl is passed. l ylhese parts are rmly secured together by dipping` when the lantern 'traine has been assenjibl id', and this method otl :securingl the upper guard ring and the bail ears greatly strengthens the upperl portions ol the tubes and increases the strength and stillness ot the lanternl frame. I, The body hoop B is provided around the opening Q23 which communicates with the lower endet the tube with an outwardly into the. lower end of the tube. This end is provided with a projecting lip 25 which is passied through a slit, formed in the body hoop below the collar Q4, and bent. down on the inner sident the body hoop. This collar and this lip hold the tube tirinly in its proper position while assembling the parts and also strengthen the connection nafter the parts have been permanently Secured by dipping. The main upright guard members l extend inwardly adjacent vto the body hoop, or at. the waist of the lantern frame, and are secured to theV body ,hoop by any suitable means. "the upright supplemental guard lower portions olf the air tubes by having their hooked upperends 25 inserted into thetubesI through openings formed in the lower sides thereo'neai.' the lower ends olf the tubes. The lantern trame is also provided with anopen, spider or skeleton base which exposes the oil pot to view, `gives eonl venieut :u:ress to the same, and renders the l traine light and sightly. l do not claim herein the construction of the base portion of the lantern guard or trame because the same is claimed in a divisional application filed Jan. 2, 1909, Serial Kofi-70,449. I claim as my invention: l. ln a tubular lantern, the (combination of an air tube open at its upper end, an upper air chambei movable toward and from said tube, a. horizontal llange below said chamber, an elbow extending from saidv chamber down to said llange, and a ferrule arranged in an opening in said flange and connecting with the lower end of said elbow and registering with said tube, substantially as set -torth. 2. lnay tubular lantern, the combination ol' an air tube open at its upper end, an upper air chamber movable toward and from said tube, a horizontal tlange below said chamber, an elbow extending from Said chamber to ,said llangc, and a ferrnle arranged in an openingin said tlange above said tube and comprising an upper portion which connects with said elbow and a contracted lower `portion which registers With said tube, substantially as set forth. o. in a tubular lantern, the combination of an air tube open at its upper end, a horizontal flange arranged above said tube and movable toward and from the same, a shouldered terrule seated in an openinfY in said llange above said tube, and an el ow connected with the upper portion of said ferrule, substantially as set forth.
