WHMQMM HENRY J. BOURGEOIS, OF OMAHA, NEBRASKA.

LAMP.

Application filed December 9, 1915.

To all whom it may concern:

Be it known that I, HENRY J. BOURGEOIS, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to an improvement in that class of lamps known as sanctuaryoil burners, and has for its object to provide lamps so constructed that no attention will be required, except at long intervals of time, for replenishing the fuel supply, and which will be convenient and durable in use, and will consist of few and simple parts so that manufacture will be economical.

The invention consists of the novel construction, combination and arrangement of parts as described therein and claimed, and as illustrated in the drawings, wherein,-

Figure l is a view of the device in vertical section. Fig. 2 is a side view of the float. Fig. 3 is a plan view of the float. Fig. at is a broken view of a hook used for lifting the float and wick from the fuel receptacle. Fig. 5 is a side view of the burner. Fig. 6

is a view of the burner in longitudinal sec-' tion. Figs. 7 and 8, respectively, are top and bottom plan views of the burner.

Referring now to the drawing, numeral 9 indicates a receptacle for containing oil or other suitable liquid fuel for producing artificial light by use of a burner.

At 10 is indicated a container for air, or

' float. It may have any suitable form, but

preferably it is substantially elliptical in cross section, and, by use of the tubular section 11 which is disposed parallel with its longitudinal axis, a cylindrical recess 12 is provided which opens upon its top and bottom.

Numerals 14 indicate a pair of eyelets which are mounted on the upper side of the float so that when it is necessary to refill the receptacle with oil or other liquid fuel, the float may be conveniently removed from the receptacle by use of the implement 13 shown in Fig. 4.-.

A wick 15 is provided consisting of any suitable rectilinear fibrous material which will have sufficient rigidity to resist bending when stresses are directed longitudinally thereof by the burner or the float. The wick at its lower end is preferably provided with a weight 16 for disposing it centrally Specification of Letters Patent.

of the receptacle and thereby maintaining the float midway between the walls of the receptacle.

The burner consists of a capillary tube or guide 17 provided at its upper end with a spherical chamber 18 preferably having a flaring terminal wall 00 so that the wick may pass therethrough without being unduly obstructed, the tube 17, as best shown in Fig.

6, being provided with a boss or collar 19 havlng an outwardly divergent wall to pro'' vide projections 20 for engaging the wall of the recess 12 for maintaining the burner in fixed relation with the float, and by means of the engagement of the projections 20 with the wall of the recess 12 the burner may be adjusted longitudinally of the float. It will be understood that, in instances where several small lamps are employed, the work of supplying them with fuel or of adjusting them would generally require considerable time and attention. Among the advantages to be derived by use of the lamps herein described, it may be stated that no attention is required for their care except at long intervals of time. After the receptacle 9 has been filled with liquid fuel, the device is deposited therein. The oil will be conducted upwardly of the burner to the upper end of the wick where ignition. occurs, and gas will form in the chamber 18 for aiding combustion. The rigid wick flts loosely in the tube of the burner, and as the fuel supply gradually diminishes the float will be lowered within the receptacle, the upper end of the wick being gradually consumed. The receptacle is preferably constructed of transparent material so that the limited degree of light produced, discharges all of the functions required for these lamps.

It will be understood that the specific gravity of the liquid fuel may not be uniform, and that if the specific gravity is greater the buoyancy of the float will also be greater, and therefore it is desirable that means for adjusting the burner longitudinally of the float be provided, and it is considered that the means for this purpose are simple and convenient in use.

Having fully described the construction, a further explanation relating to operation is not necessary. While small details have been explained I do not wish to be understood as limiting myself thereby any further than expressed in the appended claims,

bular member within said recess, and a rigid wick supported by the receptacle having a part projecting upwardly within the tubular member..

2. A lamp for a liquid fuel receptacle,

comprising a hollow casing for floating on said fuel, said casing being substantially elliptical in cross-section and provided with a recess opening on its top and bottom, an upright, rigid wick supported by the receptacle and having a part disposed in the recess of the casing, and a tube provided with a spherical chamber at one of its terminals eircumscribing the wick while disposed in the recess of the casing.

3. A lamp for a liquid receptacle, comprising a hollow casing substantially elliptical in cross-section for floating on said liquid fuel, said casing being provided with a recess opening on its top and bottom and with upwardly projecting eyelet members adjacent to said recess, an upright, rigid wick supported by the receptacle having a part disposed in said recess, and a tube ad- Gopies of this patent may be obtained for five cents each, by addressing the Washington, I). C.

justably supported in said recess while circumscribing the wick. a

4. A lamp for a liquid fuel receptacle, comprising a float having an elongated re cess opening on its top and bottom and adapted to be disposed on the liquid fuel, a tube arranged for longitudinal adjustment while disposed in said recess, and an upright, rigid wick disposed in said tube in engagement with the receptacle.

5. A lamp for a liquid fuel receptacle, comprising a buoyant member supported by the liquid fuel, a tube carried by the buoyant member, and a rigid wick having its upper end disposed in the tube, its lower end being provided with a weight for a support upon the bottom of the receptacle.

6. A lamp, comprising, in combination with a receptacle for containing liquid fuel, a rigid, substantially rectilinear wick provided with a weight adapted to be disposed with its weight seated on the bottom of the receptacle, a tubular burner provided with a spherical terminal circumscribing the wick, and a float circumscribing the tubular burner while connected therewith.

In testimony whereof, I have aifixed my signature in presence of two witnesses.
