UNITED STATES PATENT OFFICE.

FRANCIS LECLAIR, OF NEW YORK, N. Y.

LAMP.

Specification of Letters Patent No. 18,818, dated December 8, 1857.

To all whom it may concern:

Be it known that I, FRANCIS LECLAIR, of the city, county, and State of New York, have invented a new and Improved Mode of Regulating the Heating Flame of Gas- Generating Lamps; and I do hereby declare that the following is a full and eXact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention I will proceed to describe the separate parts.

A, Figure l, is the lamp reservoir.

Bis a wick extending to the gas generating chamber C.

D, is the heating flame tube.

E is the thimble for regulating the heating flame.

F is the handle for turning the thimble E, to raise or lower it on the heating tube D.

Gr is the plane for the handle F to move on, and H is a shield for protecting the heating flame.

J is the common or bat-wing burner which is readily lighted after a short time of action of the heating llames.

L or M is the separate wick independent of wick B.

In Fig. 3, H is the revolving shield and rests on the top of the reservoir A as a bear for it, and on which A revolves. This shield is open on one side for the purpose of easily operating the thimble E by the handles F sliding on plane G. The tube D through which passes wick B in Fig. l, has attached to its'lower end a screw G, which screws into the top of the reservoir A and is the plane on which the handles operate clasping between it and the top of the reservoir, the bottom piece of the shield, H, holding it securely in its position, and at the same time allowing it to revolve. The top of the shield is snugly fitted around the generating chamber C, thus allowing it to be revolved so as to protect the heating flames from the side where the atmosphere is pressing hardest, thus preventing the flame from flaring and causing it to burn steadily; c, the chains attaching the thimbles to the tube D.

A is the reservoir in which the fluid is contained out of which the gas is made and into which reservoir the wicks enter. The wicks L and M in Fig. l carry the fluid up to the heatingburners and the wick B carry it into the generating chalnber C, where it is converted into gas and from whence it escapes through burner, I, where it is con sumed, making a beautiful and brilliant light.

I am aware that shields have been used for protecting the heating {iame in some instances. I therefore do not claim the shield itself as new. But- What I claim is-w The shield H constructed and arranged as described, so as to be held in its position by the screw G, and operating between N and the top (a) of the reservoir (A) as set forth.
