LANTERN. a

SPECIFICATION forming part of Letters Patent No. 359,341, dated March 15, 1887.

Application filed July 14, 1886. Serial No.207,970. (No model.)

To all whom it may concern:

Be it known that I, LEwIs F. BE'rTs, of New York city, county of New York, and State of New York, have invented certaiii new and useful Improvements in Lanterns, of which the following is a full, clear, and exact description,- reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention has relation to lanterns, and especially to that class employing side tubes and known as tubular lanterns, though some of the improvements may be applied in connection with lanterns of any class.

Among the objects of my invention are the provision of simple, cheap, and effective means of securing the bail or handle in the upper part of the lantern, the provision of a simple and substantial form of cross-tube, which sustains the central air-pipe and unites the side tubes, and the formation of the oilfount, its top, and. base in such manner as to make all strong and durable, economizing in the consumption of material andin the fitting and securing of parts, and to lock the basepiece and fount together in a simple, easy, and perfectly secure manner without the use of solder.

To accomplish all of this, and to secure other advantages, as will hereinafter appear, my improvements involve certain new and useful peculiarities of construction, relative arrangements or combinations of parts, and details of manufacture, as will be herein first fully described, and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a partial section and'elevation of a complete lantern constructed and arranged for operation in accordance with my invention and involving myimprovements. Fig. 2 is an elevation of the bail or handle detached, showing the formation of the parts which constitute the axes about or on which the bail is allowed to turn or swing.

Fig. 3 is a side elevation of one of the clips employed in mounting and securing the bail upon the cross pipe or tube. Fig. 4c is an end elevation of the cross-tube with one of the bail-clips in place. Fig. 5 is a plan of the 5e blank from which the cross-tube is formed,

. globe.

and Fig. 6 is a vertical longitudinal section of the cross'tube. Fig. 7 is a plan view of the perforated globebottom detached from the Fig. 8 is a plan of the blank from which the lantern-base is formed, the dotted circle indicating the margin of the piece which is removed to form the top of the oil-fount, leaving the opening which receives the bottom of the fount. Fig. 9 is a view in sectional elevation showing the top of the oil-fount, the body thereof, and the lantern-base separated from each other, but ready to be joined for use in accordance with this part of my invention. Fig. 10 is a view of the upper portion of the lantern, showing both side tubes and the central air-pipe in sectional elevation.

In all the figures like letters of reference, wherever they occur, indicate corresponding parts.

A is the bail or handle, the ends of which are stamped or pressed, as best shown at Fig. 2, so that the parts a a are smooth and cylindrical and terminated by shoulders I) b, which operate to prevent the hail from sliding longitudinally in the clips. This formation removes any inequalities in the wire at the parts which form the hinge, allowing the bail to turn smoothly.

B B are the clips by which the bail is secured to the cross-tube. These are formed of thin metal, as tin, being of about the length of the portion a of the bail and creased, as at c 0, so as to fit well around a and elevate the bail slightly above the cross-tube. are slipped upon the ends of the bail and then made to enter the slits in the cross-tube, the lower portion of each clip being bent as shown in Fig. 4, so as to form the outwardly-spreading ends (1 d and the c'reases e e. The margins of the slits in the cross-tube enter the creases e, and the clips and bail are thus sustained in the proper position and at the proper height above the surface of the tube.

B represents the cross-tube, which serves to establish communication between the airtubes 0 O and the central air-pipe, D. The cross-tube is made from a blank, as represented in Fig. 5, the same being recessed, as f f, so that when the blank is turned up the tube will have an opening, as g, Fig. 6, on one 10c The clipsv side and slitted, as at h 71, so that the resulting tube may receive the clips in the manner indicated in Figs. 1 and 4. The tube so formed is passed through perforations in the walls of the central ainpipe, D, and soldered in place. The air-pipe D is capped, as at z". The tube B is thus easily and quickly made, and is thoroughly braced in its seat, affording a passage for air from D to O 0, same as in former constructions, wherein the cross-pipe has been made in two parts, the ends of which were united with the central air-pipe. The tube B having been located and secured, the clips, with the bail mounted thereon, are introduced into the slits 71 71, and then the tubes 0, or the elbows thereon, may be connected with the ends of B. Solder is applied in the creases c e, the form of the clips and the location of the parts which embrace the bail being such as to facilitate the application of the solder without danger of soldering the bail fast, a difficulty commonly experienced in former constructions.

E is the lantern-globe, and F the metallic bottom, upon which it rests. The radial perforations I; admit ingress and egress of air outside the burner-cone and permit theintroduction of a lighted match. The central perforation, 1), fits over the burner-eone.

G is the body or shell of the oil-pot or oilfount. His the base piece or rim, forming an enlarged vase, upon which the lantern may rest, and I is the top of the oil-fount, upon which the lower ends of the air-tubes are secured, and which receives the burner and the air-chamber J. The oil-fount has an outwardly-projecting bead, as at Z, near the bottom, and an inwardly-projecting bead, as at m, near the top. It is drawn or spun orstamped in one piece for greater solidity and security and for eheapness of manufacture. The basepieee II is formed from a circular blank, as indicated in Fig. 8, the central portion being cut out, as along the dotted circle 11, of which the diameter is just equal to the exterior diameter of the fount or shell G. The central portion is preserved to form the cover or top I, and it is of the proper size for that purpose, requiring no further cutting or trimming. The bottom of the oil-fount is inserted in the central opening in H, the bead Z resting upon the upper surface of the margin of the opening, and then to lock the rim or base and fount together the bottom of the latter'is pressed or spun out, as at 0, Fig. 1, so as to clamp the rim tightly against the bead Z. This makes a perfectly secure joint, and requires no solder, and admits of no waste of material. The cone or top I is inserted in the fount, rests upon the bead m, and is secured by bending the margin of G down upon it. This joint may be soldered, if desired, so as insureits being perfectly oil-tight. The joint is circular, and the solder is easily and rapidly aeeomplished. The oil-pot so made and mounted is rigid in all its parts, and when manufactured in large numbers can be rapidly and accurately made and mounted with practically no waste of material.

In drawing up the oil-pot the material of the vertical wall is gradually thinned,and consequently weakened, toward the mouth or upper margin, the bottom part remaining substantially unchanged. Heretofore it has been the ordinary custom to close the mouth of the shell by a piece soldered therein, which piece afterward constitutes the bottom of the oilpot. This construction left the oil-pot thinnest and weakest at the bottom and liable to leak at that part; but by myim proved method the weakest part of the shell is located at the top and the soldered joint (if solder be used) is not liable to leak.

Having now fully described my invention, what I claim as new herein, and desire to secure by Letters Patent, is-

1. The combination, with the bail and the slitted cross-tube passing through the central air-pipe, of the creased clips secured within the slits in said cross-tube, substantially as shown and described.

2. The combination of the central air-pipe, the slitted cross-tube passing therethrough, the creased clips secured within the slits in the cross-tube, the side pipes communicating with the cross-tube, and the bail having the eylindriealportions at each end confined within the clips, substantially as shown and described.

3. The herein-described method of constructing the oil-pot, consisting in drawing or stamping the bottom and vertical wall together, forming the base-rim from a circular blank and the top from the central portion removed from said blank and uniting the parts, substantially in the manner shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.
