TUBULAR SPECIFICATION forming part of Letters Patent No. 572,949, dated December 15, 1896.

Application filed July 8, 1895. $erial No. 555,300. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES BERGENER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Tubular Lanterns; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-letters marked thereon.

My present invention has for its object to provide an improved lantern particularly adapted for use on railroads, and in which the globe is adequately protected from breakage and the lantern-frame strong enough to sustain the shocks to which it is liable to be subjected, and one well adapted for the burning of ordinary kerosene without liability of bein g extinguished by high winds or shock; and to these and other ends it consists in certain improvements and combinations of parts, all as will be hereinafter fully described, and the novel features pointed out in the claims at the end ofthis specification.

In the drawings, Figure l is a sectional view of a lantern constructed in accordance with myinvention, a portion of the upper part being shown in elevation; Fig. 2, a similar view taken at right angles to the plane of Fig. 1; Fig. 3, a horizontal sectional view with the globe removed; Fig. 4, a side elevation of the base, showing the globe-lifting device; Fig. 5, a horizontal sectional view on the line 00 a: of Fig. 1.

Similar reference-letters indicate similar parts.

The base of the lantern is composed of the ordinary oil-pot A, having the usual neck a, into which fits the slip-burner B, 0 indicating the air-chainber around the burner with which the tubes D communicate, and E the burnercone, fitting the top of the air-chamber.

F indicates the globe of the Ordinary type used in railroad-lanterns, resting upon the perforated globe-plate G. This globe-plate differs from the ordinary form in having the outer portion upon which the globe rests slightly depressed, forming a slight groove between the central part and the peripheral bead or flange 9, preventing the globe from slipping laterally when one side of said plate and the globe are elevated for lighting, as will be described, and it is also provided with an operating'handle g, formed of a wire loop, passing around one of the guard-wires H.

Secured to the base of the lantern and extending upwardly therefrom are the vertical guard-wires l-I, (preferably formed of doubled wires,) engaging a wire ring H at the upper end, and between this ring and the base are arranged one or more horizontal wire guardrings H passing through the vertical guards forming a rigid and eflicient basket or guard for the globe not liable to be broken. Secured also to the top ring H are the wire ears h, to which the bail J is attached in the usual manner.

The upper or cover section of the lantern embodies a hood or deflecting-plate K, hinged at 7.; to the ring 1-1 and fastened at the opposite side by the ordinary spring-catch K This plate K is provided with a short collar K, and over it is arranged a dome L, with the lower portion slightly flaring and projecting a slight distance below the top of the collar K, while its upper end is covered by a plate L, and beneath said plate is aseries of perforations L for the escape of the products of combustion. A guide ring or flange M is arranged inside the dome, through which pro jects the upper end of the sleeve or hell N, having the flange a at its lower end and resting upon the upper end of the globe.

Between the flange n and the ring M is arranged a spiral spring Z, holding the globe pressed downward upon its plate, the motion of the sleeve being limited by a cross-pin O in the lantern-top passing through two of the vertical slots P, formed in the sleeve. D D indicate tube-sections on opposite sides of the lantern connected to the dome and plate K, their upper ends entering the air-chamber Q, formed between the dome and sleeve N, while their lower ends are slightly larger than the upper ends of the tubes D and are arranged to receive them and make a tight joint with them when the upper sect-ion is fastened down by the catch.

R indicates short dividing-plates arranged H and also through the air-tubes D, the whole ICO in the air-chamber Q, and extending vertically across the inner ends of the tube-sections D, their function being to prevent the circulation of air around in the chamber Q and to direct a portion of the air entering said chamber from below into the tubes.

IV hen the lantern is lighted, the hot air and products will pass up through the sleeve N an d out laterally through the perforations L while fresh air will enter through the perforated globe-plate and will also be drawn'in from the chamber Q. by the downdraft in the tubes caused by the rise of the air in the globe or chimney from the chamber beneath the burner. By this arrangement the extinguishment of the flame by high winds or rapid movement of the lantern is prevented, currents, which otherwise might extinguish the flame, being equalized in a manner well understood by those skilled in the art.

When the lantern-top is closed, the springpressed sleeve N holds the globe and globeplate down, and when desired to light the wick without opening the top the operator simply raises the handle'g on the globe-plate, as in dotted lines in Fig. at, tilting said plate 011 the burner or the guard, if desired, raising the globe into the dome against the tension of the spring, leaving an aperture between the plate and globe on the side opposite the handle sufficiently large for the illtroduction of a lighted match, which may be applied to the wick. I by preference locate the handle substantially in line with the opening in the burner-cone, so that the wick can be readily reached.

\Vhen it is desired to remove the globe to clean it or for any other purpose, the top section may be tilted back on the hinge, as shown in dotted lines in Fig. 2. The perforated globe-plate will be prevented fromfalling out by reason of the connection of the handle g with one of the vertical guardavires.

The advantages of my construction, whereby a tubular railroad-lantern is provided, will be obvious to those skilled in the art.

I claim as my invention 1. In a lantern, the combination with the base containing the oil-pot and burner and the air-chamber around the latter, the globe, the tubes independent of the globe connected to the air-chamber and open at their upper ends, the vertical guard-wires, the horizontal ring connected permanently to their upper ends and to the tubes, and an intermediate horizontal guard-ring, of the top plate hinged to the top ring of the guard-frame having the dome, the spring-pressed sleeve therein, the tube-sections connected to the dome and cooperating with the upper ends of the lower tubes when the top is closed, substantially as described.

2. In a lantern, the combination with the base containing the oil-pot, burner and airchamber, the globe, the vertical tubes independent of the globe connected to the airchamber, the vertical guard-wires intermediate the tubes, the ring connected permanentl y to their upper ends and to the tubes and the intermediate guard-ring, of the top plate having the perforated dome, the springpressed sleeve therein having the apertures and cooperatin g with the top of the globe and forming an air-chamber between the sleeve and dome, the tube-sections on the plate open at their lower ends and opening into the airchamber, the vertical strips extending across said tube-openings, a hinge connection between the top plate and the ring on the base, arranged between the tubes, and a catch for holding the top plate down with the tube-seetions engaging the ends of the tubes on the base, substantially as described.
