XVILLIAM S. DICLEVEE, OF NE\V YORK N. Y.

FORCED-DRAFT LAMP.

SPECIFICATION forming part of Letters Patent No. 320,080, dated June 16, 1885.

Application filed April 4, 1884.

To all whom, it may concern:

Be it known that I, WILLIAM S. MOLEWEE, ofNew York, in the county and State of New York, have invented a certain new and useful Improvement in Lamps, of which the following is a specification.

I will describe a lamp embodying my improvement in detail, and then point out its various features in claim.

In the accompanying drawings, Figure 1 is a vertical section ofalamp embodying my improvemcnt, and Fig. 2 is a horizontal section of the same.

Similar letters of reference designate corresponding parts in both figures.

A designates a base-piece of any suitable material.-as, for instance, sheet metal. It is provided with suitable apertures or openings, (1, for the entrance of air.

In the base-piece is a chamber, A, containing a train of wheelavork, B, and actuated by a spring or its equivalent. This chamber is provided with perforations b, through which air may pass.

Above the base-piece A is a shell, (J, of sheet metal, shown as cylindrical at thelower portion and flaring at the upper portion.

D designates a reservoir for containing oil or other burning-fluid. It is arranged within the shell 0, and conforms to that partof the shell wherein it is located. It is provided with lugs c, which rest upon lugs (1, extending from the shell. In this way the reservoir is supported in the shell. A space is left for the circulation of air between the reservoir and the shell.

Below the reservoir and within the lower part of the shell are fans E F. The fan E is of large diameter, extending nearly across the shell; but the fan F is of much smaller diameter. These fans are mounted on a shaft, G, which is rotated by the train of wheelwork B.

The reservoir is furnished with a burner, H, which is here shown as having two wicktubes, although it may have but one. This burner may be removabl y secured to the reservoir by screw-threads or other suitable means, and the opening wherein it fits may serve as the filling-month for the reservoir.

The wick tube or tubes of the burner may (No model.)

be provided with any suitable means for adjusting the wicks. As here shown, ratchet or star-toothed wheels arranged on shafts e are employed for this purpose.

The shell 0 is provided with a removable cover, 0. This cover is shown as secured in place by screw-threadsf; but it may be secured in place by other means, or it may be merely slipped on. It extends over the top of the reservoir at a suitable distance therefrom to allow of tl'lecirculation of air between it and the reservoir.

The cover 0 has at the apex or center an air-chamber, I, extending to about a level with the tip of the wick-tubes, and surmounted by a deflector, J, whereby air is caused to impinge upon the flames which emanate from the wick-tubes.

The airchamber I is preferably formed in two sections, the upper of which is connected to the lower by ahinge, g, and is capable of being secured to the other when closed by a spring-catch.

The upper section of the air-chamber may be swung back to afford access to the tips of the wick-tubes.

In the upper section of the air-chamber is a perforated diaphragm, K.

The deflector J has two slots, one over the tip of each wick-tube.

The air set in motion by the fans E F rises through the shell to the burner and supports combustion.

No chimney or other draft-inducing device is required.

A globe or shade may be used in conjunction with the burner, if desired. Y

By using two fans arranged one above the other upon the same shaft, one of which is of smaller diameter than the other, I provide for subjecting all of the ascending column of air to the direct action of the fans.

I am aware that lamps have been constructed provided with a train of wheel-work operating a single fan to set in motion a current of air for supporting combustion at the burner. I use two fans arranged one above the other, one of said fans being of smaller diameter than the other. Vhen but one fan is used, much of the ascending column of air is not brought within its influence as it passes upward near the shaft upon which the fan is arranged, and

so comes bu-tslightly in contact with the blades of the fan which are narrowest at=that point,-

vided with air-inlets, a train of wheel-work, two fans arranged one-above the other upon the-same shaft,'"oi1e of i said fansbeing of less diameter than the other areservoir, aburner onthe reservoir, an air-chamber arranged about the burner, a perforated diaphragm within the air-chamber, and a deflector surmounting the air-chamber, substantially as specified.

W. S. MOLEWEE.
