IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 32,161, dated April '23, 1861.

To all whom it may concern.-

Be it known that I, E. B. COFFIN, of J ohn ston, in the county of Providence and State of Rhode Island,-have invented a new and Improved Lantern; and I do herebydeclare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- 7 Figure 1 is a vertical central section of my invention, taken in the line x m, Fig. 2; Fig. 2, a horizontal section of the same, taken in the line 3 3 Fig. 1.

.Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to obtain a lantern for burning kerosene or coal oil.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a glass globe, the lower part of which isfitted within a base, B, perforated at its side, as" shown at a, and encompassed by a perforated band, G, which forms a register to vadmit more or less air into the lower part of the globe, as may be "desired.

' D represents the fountain or oil-reservoir of forated sides, asshown ate, and a 'tnbe,f, runs centrally through compartment 6, to admit of the glass chimney F passing through into the upper compartment, 0, of cylinder G, as shown clearly in Fig. 1. v

H is a horizontal deflector or plate, which is fitted in the upper compartment, 0, of cylinder G. This plate is of circular form and of smaller diameter than the cylinder G, in order to allow a space, all around between itsedge and the cylinder. The plate ordeflectorH is retained in proper position by elastic lugs or projections h,-which extend from the edge of plate H and bear against the inner small dome-shaped chamber, 1, the sides of which have, apertures'i in them.

7 J represents valves, which are simply metal plates bent in V form and fitted in slots over the apertures z, said'plates or valves being allowed to swing freely in the sides. of the dome or chamber ,1. The lower part of the dome or chamber I communicates with the upper apartment, 0, of cylinder G by perforationsj, and the lower part of the compartment b of cylinder G communicates with the globe A by perforations k.

The wick may be raised and lowered by turning a small shaft, d, which extends through the flange at the bottom of the fountain D, the upper part of said haft being a serew, e'. which gears into a worm-wheel, f, on the end of the shaft 9-, which has the small wheels on it. that engage with the wick. (See dotted lines in Fig. 1.)

From the above description it will be seen that the flame is supplied with air which passes through the perforations e of the compartment b of cylinder G, the air passing down through. the perforationsk at the bottom of said compartment into the globe A, and thence through the perforations of the burner, the warm air passing up the chimney F and through the upper compartment, 0, ofcylinder G'into the chamber I, and out through the openings or apertures i. The valves J, inconnection with the deflector H, prevent any back-draft, the valves closing on the windward side of the dome or chamber 1-, and the supply of air to the flame is rendered very constant in consequence of its circuitous route and the perforations through which itfpasses. The lower perforations may be more or less opened, to admit the air in greater or lessquantity into the lower part of the globe A, by regulating the register or band C, and in case of the'wind blowing strongly, so as to.

affect the flame, they may be nearly or entirely opened.

Having thus described my invention, what I claiin as new, and desire to secure by Letters ranged substantially as and. fer the purpose.

specified.

Patent',is-' In connection with the cylinder'G, e a1-0i1 burner E, and chimney F, theval'ves J in the dome or chamber 1, the deflector or plate H in the cylinder G, and the register 0 at the base of the lantern, when all are combined and ar- E. COFFIN;
