WILLIAM S. HAMM, OF LAKESIDE, ILLINOIS.

LANTERlE-I-BURNER.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed April 8, 1907. Serial No. 366,998.

To all whom "it may concern:

Be it known that 1, WILLIAM S. HAMM, a citizen of the United States, and resident of Lakeside, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Lantern-Burners, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to lantern burners which comprise a wick-tube and a wick raiser in the form of a star wheel carried by the shaft.

The object of the invention is to render the wick raiser more certain in its action, particularly for the purpose of preventing the descent of the wick due to jarring or violent motion of the lantern; and it consists in means for frictionally holding the star wheel or its shaft against rotation, and, more specifically, in a spring yieldingly forcing the shaft against its hearing.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a burner, a portion of the wick being shown; Fig. 2 is a side elevation of the same from a different point of view; Fig. 3 is a sectional view on the line 3-43 of Fig. 1, the wick being omitted Fig. 4; is a side elevation of the burner, partly in section, showing a modified form of construction; and Fig. 5 is a sectional view on the line 5-5 of Fig. 4, the wick being omitted.

The burner head is represented at 10 and comprises a chambered body, preferably of sheet metal, having a threaded shank 11 for engagement with the lantern font, not shown. The wick-tube 12 extends entirely through the body 10, projecting downwardly a suitable distance to guide the wick, and upwardly a suitable distance in order that the flame may be maintained in the proper position in the lantern body.

When a fiat wick tube is used, as in the construction illustrated, a plurality of star wheels 13, 14 and 15 aroused to raise the wick, and are fixedly mounted on a shaft 16 projecting through the body 10 and being adjacent to the wick tube, the latter being apertured to permit the star wheels to project into its chamber. A grip 17 is applied to the outer end of the shaft to facilitate its control.

A bowed spring 18 is fitted within the chamber of the body 10, its ends bearing against the shaft 16, as shown at 19, 20, and its crown bearing against the side of the body, as shown at 21.

As illustrated in Figs. 2 and 3, the apertures in the walls of the body 10 within which the shaft 16 is located, are somewhat larger than the diameter of the shaft, permitting the latter to be forced, under the influence of the spring, against the side wall of the tube 12, so that its bearings consist of the tube wall and the spring ends. By this means a long bearing is provided for the shaft in the Wall of the wick tube, and the spring ends are so shaped, as represented at 19, 20, to constitute bearings of considerable areas, there by reducing the wear on the shaft and its bearings to a minimum.

The spring is contractile in character, that is to say, its elasticity tends to urge its ends toward each other and hence, when fitted within the burner body, it forces the shaft toward the wick tube.

It is important that the shaft bearings be prolonged, and this is preferably secured as above described and as illustrated in Figs. 2 and 3. Other means, however, for providing an extended bearing, in lieu of the wall of the wick tube, may be provided, as, for example, the protruding lips 22, 23, formed around the apertures in the body 10, which accommodate the shaft 16, as illustrated in Figs. l. and 5, such apertures in this case being so disposed that that side of therlips which is opposite the spring 18 constitutes the shaft bearing, holding the shaft out of contact with the wick-tube.

While I have shown and described a wicktube extending entirely through the body of the burner and a star wheel device for raising the wick, taking the form of a star wheel, it will be understood that the invention is applicable to any form of burner in which. there is a wick passage and a star wheel operated by a rotatable shaft for raising and. lowering the wick.

I claim as my invention- 1. In a lantern burner, in combination, a

chambered body, a wick-tube, a star-wheel projecting into the tube, a shaft continuously bearing against the wick-tube and carrying the star-wheel, and a leaf-spring located within the body and reacting between the inner walls thereof and the shaft shaft to yieldingly hold the latter against the to yieldingly hold the latter to the outer Wick-tube, the ends of the spring being pro- 3 wall of the wick-tube. longed parallel with the shaft to form ex- 2.
