INCANDJESCENTBURNER FOR LANTERNS, &,o.

SPECIFICATION forming part of Letters Patent No. 593,925, dated November 16, 1897.

Application filed February 6. 1897- Serial No. 622,310. (No model.)

To all whom it may concern:

Be it known that-I, JAMES WILLIAM DEAR- ING, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Incandescent Burners for Lanterns and Like Articles, of which the following is a full, clear, and exact description.

The object of my invention is to provide a burner of the incandescent type in which threads or filaments of asbestos or like material or platinum Wire will be supported over a flame, preferably a spirit-flame.

Another object of the invention is to provide a means whereby the filaments may be adjusted in a manner to center them upon the lens of a lantern, for example.

Another object of the invention is to provide such a support for the filaments that they will be rendered incandescent from end to end.

A further object of'the invention is to provide a means of attachinga fuel-reservoir containing oil or spirits to the body of the lantern in a manner which will hold the two parts firmly together yet admit of the parts being quickly and conveniently removed or connected and a perfect draft be obtained. A

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section taken through a bicycle-lantern and the improvement applied thereto. Fig. 2 is a horizontal section taken on the line2 2 of Fig. 1, and Fig. 3 is a perspective view of the incandescent attachment to the burner of the lamp.

The main feature of the invention consists in a sleeve 10, adapted to slide over the wicktube of the burner.

provided atits upper portion with a horizontal flange 11, and uprights 12 are projected from the end portions of the flange. Each upright is usually provided with notches or depressions 13 in its side edges and with apertures 14. Said uprights 12 are adapted to The sleeve is preferably hold asbestos or platinum threads or filaments 15, passed through the apertures thereof, as I shown in dotted lines in Fig. 3 and in positive lines in Fig. 2, but the filaments or threads 15 may be made of anymaterial capable of being rendered incandescent. The sleeve carrying the filaments or threads 15 is used in connection with a receptacle 16, adapted to conapertures 19 in its sides and with other apertures 20 in the top, so that a circulation of air is obtained, the air passing through the side openings 19 and around the burner through the top openings or apertures 20.

The body portion 21 of the lamp may be made of any desired formation and is provided at its lower portion with a set-screw 22, adapted for engagement with the casing or box structure 18 when the latter is introduced in the bottom of the body portion of the lamp.

At the back of the body portion of the lamp a reflector 23 is located opposite a lens 24., which is at the front of the lamp or lantern, the lens 24 being located in a casing representing the frustum of a cone.

The top portion 25 of the body of the lantern is apertured for the escape of heat, and its back portion is provided with a handlesection 26, shaped to be fitted to a bicycleframe A channel 27 is formed in the bottom of the body, which body will surround the top structure or casing 18, as shown in Fig. 1, the setscrew 22 crossing the channel 2'7. Slots 28 are made in the bottom wall of the channel 27, adapted to receive lugs 29, formed upon the box structure or casing 18, as shown in Fig. 2. The lugs of the box structure or casing and the receptacle 16 are so turned in the body that the lugs 29 will be moved around in the channel 27 until one of them strikes a lug 29, secured in said channel adjacent to the set-screw 22-, as is also shown in Fig. 2.

lVhen the set-screw is adjusted, one of the lugs 29 will be between the screw and the stop-lug 29.

lhe sleeve of the incandescent attachment is slipped over the top of the wick-tube 17, the wick 30, located in said tube, being of any desired construction. The sleeve 10 may be adjusted vertically, so as to bring the incandescent filaments or threads opposite the central portion of the lens 2i, and the flame from the wick may be entirely extinguished by drawing upward the sleeve 10 to apredetermined extent. As soon as the wick is lighted the flame produced by the alcohol or other material used will almost immediately cause the filaments or threads 15 to become incandescent, and as burning spirits especially do not show light to any appreciable extent theinc-andescence of the filaments is in no manner interfered with, and a lantern to which the attachment is applied will show light to a great distance in advance of the lantern and over a considerable area.

A tube 31 is secured in the receptacle 16, extending from the upper portion of the fuelchamber to a point near its bottom. A filling 32, of cotton-waste or a like absorbent material, is well tamped in the tube 31, extending to the bottom of the fuel-chamber, as shown in Fig. 1. Until exhausted the liquid fuel will keep the waste saturated. The wick 3O rests upon the filling 32, receiving fuel therefrom, so that the flame will be steady and the liquid supplied to the wick will not be spilled in the top structure or casing 18 or in the body of the lamp or lantern.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A filament-carrier for lanterns, comprising a sleeve having a flange at its upper end and provided at said upper end with uprights apertured and having notches in their edges, substantially as described.

2. In a lantern, the combination of a fount having a box structure on its upper face, said box structure being provided with lugs on its upper edge, a body provided in its bottom with a channel having openings in its bottom and provided with a lug projecting into the said channel, and a set-screw at the lower portion of the body, substantially as described.
