M. V. B. BUELL, OF BUFFALO, NEW YORK.

VAPOR-LAMP.

Specification of Letters :Patent No. 28,063, dated May 1, 1860.

To all whom it may concern:

Be it known that I, M. V. B. BUELL, of Buffalo, in the county of Erie and State of New York, have invented a new and Improved Lamp; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, said drawing being a side sectional view of a lamp constructed according to my invention.

This invention relates to certain improvements in that class of lamps generallyv known as vapor lamps, those in which the burning fiuid is volatilized and gasiiied in the lamp previous to burning.

The object of the invention is to avoid the accidents attending the use of this class of lamps.

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

A represents a stand which is silnply a vertical rod ci attached to a suitable base B is a receiver or font which contains the burning fluid. This receiver or font may be of any proper shape and to its lower part a horizontal tube C is attached said tube communicating with the interior of the receiver or font and having a spherical chamber c connected with it through which chamber a tube or socket l passes. The chamber c does not communicate with the interior of the socket, but merely forms a proper support or bearing for it and permits the tube C to project beyond the rod a on which the socket d is fitted and allow-ed to slide freely, the socket being secured at any desired point on the rod by a set screw e. The outer end of the tube C is screwed into a cock D having a curved body, its outer end curving upward and having a vertical burner E screwed into it. The burner E extends a trifle above the receiver or font B, as shown clearly in the drawing. The burner is slotted down considerably below its upper end, say fve-eighths of an inch, as shown at f, or holes may be employed instead of the slot.

The operation is as follows: The receiver or font B being filled with burning fluid, and the cock D opened the fluid passes from the receiver or font through tube C, and into the vase of the burner E, which is supplied with a wick F, the supply of fluid to the burner being regulated by the cock D.

In order to light the lamp a match or a piece of burning paper is held for a few seconds to the top of the burner, until the vapor is generated. The vapor ignites, and the fluid is then volatilized by the heat of the illuminating flame, no auxiliary flame being required nor any heater. This result is due to the depth of the slot f or perforations whichever may be used the depth of the slot causes the sides of the burner to be heated as well as the top, and the illuminating flame is thereby made to generate its own gas.

By having the burner E, separated from the receiver or font B, the danger of explosion by a pressure of gas therein is avoided as a great volume of fluid cannot be volatilized, as it is not in close proximity to the flame the fluid therefore is only volatilized as it is burned. By having the tube O horizontal or approximating to such position, and the burner extending upward above it, the burner cannot overflow when the cock is fully open and the receiver or font full, a contingency which is liable to occur in those lamps which have their receivers higher than their burners.

W'hat I claim as my invention and desire to secure by Letters Patent is- Having the burner E, connected to the receiver or font B by a tube C, so that the top of the burner will extend a little above the highest level of the fluid in the receiver or font B for the purpose specified.
