JOHN HENRY STONE, OF TORONTO, CANADA.
LAMP-BURNER.
SPECIFICATION forming part of Letters Patent No. 638,293, dated December 5, 1899.
Serial No. 693 ,048. (No model.)
T0 at whom it may concern.-
Be it known that I, JOHN HENRY STONE, of the city'of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Burners for Lanterns and Lamps, of which the following is a specification.
My inveiition relates to improvements in burners for lanterns and lamps; and the object of the invention is to provide arapid supply of still air centrally to and around the wick of the burner without undue draft; and it consists, essentially, of providing around the wick-tube, inside of the cap of the burner, a double concavo-convex perforated plate, which is supported in the burner and designed to diffuse the draft gently, as hereinafter more particularly explained.
Figure 1 is a detail of the burner. Fig. 2 is a detail of an alternative form of burner. Fig. 3 is a detail of a suitable form of burner for a lamp. Fig. 4 is a detail view.
Referring to Fig. 1 in the drawings, A represents the upper part of the oil-bowl of the lamp, provided with a suitable neck. Fitted to this neclvis a casing R, which is flared outwardly, as shown in the figure. Outside of this casing is a collar 13, forming an inclosing wall and resting at its lower edge upon the bowl. Upon it and over the casing is placed a cap D of the burner, which is provided with the usual slot d and has an outwardly-turned flange at its base. The collar is provided with a slot b, fitted to receive the wick-operatin g spindle, which has at its outer end the ordinary turning-button r. The airsupplying tubes E, used when the burner is placed in a lantern, open into the chamber around theburner through the collarB. The ordinary wick-tube R is located within the casing. The casing has vertical slots 7'' for the admission of the air, which is directed through them from the exterior chamber, this chamber being closed in by the wall of the collar and the flange of the cap. The u pper part of the casing is turned outward, as shown at r, to form a bearing for the concavo-conveX plates r and 0*. These plates are provided with slots 3 and 4, through which the wick-tube passes. They are placed with concave faces inward and the edges are brought together closely. The lower plate has the larger perforations and the upper smaller perforations. These two plates therefore form a double-convex chamberinto which the air is freely admitted by the larger perforations below, but is finely distributed by the smaller perforations in the upper plate. The air is admitted more freely through the larger perforations, maintaining a full supply in the cavity between the concave plates, which full supply is evenly distributed and continuously to the burner without permitting any flickering of the flame, and this may be used whether the burner be adapted to a lamp or to a lantern.
In the lantern form (shown in Fig. l) I have shown the cap D as formed with an outwardly-extending flange D, which fits between the collar B and an outwardly-extending flange R secured to the edge of the flaring casing. This serves to hold the cap securely in place in the swinging of the lantern.
In Fig. 2, which shows the lamp form, the flange B on the lower edge of the cap is inserted between the flange r and the outer edges of the concave disk. In either case the flange is held between surfaces and in frictional contact therewith and more socurely than whenthe cap fits outside of the collar, as heretofore.
Of course itis necessary in the construction of the burner hereinbefore referred to to provide a means whereby the cap maybe always placed in the proper position, and for this purpose I provide a projection 01 on the flange D, which is designed to fit within the vertical slot 19 cut in the collar.
In Fig. 2 any similar form of device for placing the cap in proper position may be provided. The flange D in Fig. 2 of course fits tightly in this instance into the collar 13.
In the lamp form shown in Fig. 3 I show the form designed fora lamp, in which it will be noticed that the chimney of the lamp is held on an outwardly-extending flanged annular support 5. The concavo-convex plates and the form of the bowl are practically the same.
I claim- 1. In combination with the casing having an outwardly-turned flange, the cancavo-convex plates placed with their concave faces toward each other and with their edges in turned flange of the casing, the lower of said therein for the turning spindle, a cap having plates havinglargerand the upper the smaller a depending flange fitting between the flange openings, substantially as described. of the casing and said oollarand a projection 2. The combination with the bowl, the casextending from the flange of said cap and inghavingadepending circumferential flange guided in the vertical slot in said collar, suband the collar surrounding the same, of the stantially as described. cap provided with a depending flange fitting between the flange of said casing and said JOHN HENRY STONE collar, substantially as described.
3. The combination With the bowl, the easing having a depending flange, the collar sur- 1 contact and supported by the outwardly- I rounding the same having a vertical slot 1 Witnesses:
