LAMP-BURNER.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed March 26, 1904. serial No. 200,089.

To all La7/1.0177, t may concern:

Beit known that I, FREDERICK J. LANDER, of Rochester', in the county of Monroe and State of New York, have invented certain new and useful Improvements in Lam p-Burners; and I do hereby declare the following to be a full, clear, and exact description of the same. reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to burners adapted particularly to be applied to the base or oil-font of lamps or lanterns and consisting generally of the base or attaching portion, the shell or chimney-gallery andthe wick-tube extending therethrough and provided with a wick-raiser; and my invention has for its object to provide means for retaining a lampwick within the tube when it has been disengaged from the raiser and also to provide means for raising the wick into engagement therewith.

To these and other ends my invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described and the novel features pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is avertical sectional view of a burner constructed in accordance with my invention, the wicktube and the means for retaining and raising the wick being' shown in elevation. Fig. 2 is a crosssectional View taken on the line 2X 2X of Fig. 1. Fig. 3 is a top plan view of the burner, shown with the cap removed. Fig. 4 is a horizontal sectional View on the line 4X 1X of Fig. 1, and Fig. 5 is a detail sectional view showing a modification.

Similar reference-numerals in the several figures indicate similar parts.

In illustrating my invention I have shown it applied to a lamp-burner comprising the base 1, having the threaded portion 2, by means of which the burner is attached to the usual lamp body or font, as will be understood. Extending through the base is the wick-tube 3, and at the side thereof is arranged the air tube or passage 4f. The upper end of the wick-tube extends above the base 1, and arranged between the latter and the upper end of the tube is the usual foraminous air-defiecting plate 5, from which depends the shell 6, forming the chimney-gallery. Surof the tube.

mounting the shell is the removable burnercap 7, which is preferably hinged at one side,

as indicated at the point 8 in Fig. 2, and provided with the transversely-extending iiameaperture 9, arranged in alinement with the end of the wick-tube. The burner may be provided with the usual or any preferred form of wick-raiser, and in the present illustration I have shown this as consisting of a spurwheel 10, mounted upon a laterally-extending shaft 15, journaled in the base 1 and provided at its outer end with a knurled head or operating-handle 16. In applying my invention to a burner of this description the burnertube 3 is preferably elongated slightly at its lower end, as shown in Fig. 1, and at one side thereof it is cut away to form an aperture 17 through which operates the wick-retaining device, which engages the wick to hold it in frictional engagement with the opposite side This retaining device may be constructed in any suitable manner, and the form which I have illustrated embodies a spur-Wheel 18, journaled on the bar or support 19, extending over the aperture 17 and arranged so that the teeth of the wheel are embedded in the wick suiiciently to prevent the end of the latter from being drawn out of the wick-tube by its weight when disengaged. from the wick-raiser, and yet permitting it to be removed when it is desired to insert a new wick or for any other purpose.

The grappling device for moving the wick upwardly. consists of a small rod or bar 20, arranged exteriorly of the wick-tube and extending through the base 1 and the air-defiecting plate 5. At its upper end the rod is bent,`as

shown in Figs. 1 and 2, to form an operatinghandle 25, by means of which the rod may be rotated to move the laterally-extending talon or finger 26 at its lower end into engagement with they wick through the aperture 17, as

shown in dotted lines in Fig. 1, when it may be drawn upwardly to move the wick longitudinally in the tube 3. By arranging the grappling device in proximity to the wicktube and providing it with the laterally-extending operating end which engages the side of the tube its rotary movement is limited and the talon or finger 26 cannot be operated a suiicient distance through the wick to cause the fibers thereof to be frayed or severed.

In Fig. 5 I have shown aconvenient means of mounting the retaining device, and in this IOO "is afforded to the grappling dev ice.

illustration the spur-wheel 18 is shown as supported upon an ear 37, formed by striking up a portion of the wick-tube at one side of the aperture 17, the bearing or journal for the Wheel being formed by a bur or tubular extension 28, formed at one side of the ear.

From the foregoing description it will be seen that if by accident the operator rotates the wheel 10 of the wick-raiser in the wrong direction the wick is moved out of engagement therewith, so that the wick will be held by the retaining device 18, and when the burner-cap 7 is opened on its hinge 8 access The rod 20 being moved downwardly to its lowermost position it may be rotated to the position shown in full lines in Fig. 2 and in dotted lines in Fig. 3 to cause the talon or {inger 26 at its lower end to engage the wick, and when elevated to the position shown in l'ull lines in Fig. 1 the end of the wick will then be engaged with the spur-wheel 10 of the wickraiser, permitting the wick to be elevated in the usual manner when the shaft 15 is rotated in the proper direction, as will be understood.

The devices constructed in accordance with my invention are simple in form and capable of being applied to lamp-burners without necessitating any material change in the construction thereof, and when so applied the obvious inconvenience and disadvantage of removing the burner from the lamp-font when the wick is disengaged from the raiser is overcome.

I claim as my invention- 1. The combination with a lamp-burner comprising a base, a shell surmounting the base having a plate and a wick-tube extending through the base and plate and provided with an aperture, of a wick-raiser located in the base and extending into the tube, a wick-retainer extending into the tube beneath the base, a grappling device journaled in the base and plate and movable longitudinally of the tube, having a finger adapted to extend through the slot in the tube and engage the wick between the wick retaining and raising devices.

2. rlhe combination with a lamp burner comprising a base, a shell sui-mounting the base having an air-deflecting plate, a removable burner-cap on the shell and a wick-tube having its lower end extending beneath the base and provided with an aperture and an upper end projecting into the burner-cap, of a wick-raiser extending into the tube, a wickretainer projecting through the aperture in the tube and a grappling device movable longitudinally of the latter and revolubly supported in proximity thereto, an operatinghandle on the device located within the burnercap and a linger also arranged thereon and adapted to be projected through the aperture in the tube into engagement with a wick.
