NICK-RAISING DEVICE FOR LANTERNS.

Specification of Letters Patent.

Patented June 27, 1911.

Application filed May 12, 1909. Serial No. 495,478.

To all whom it may concern:

Be it known that I, RICHARD J. KELLY, a citizen of the United States, and resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Wick-Raising Devices for Lanterns, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to provide a lantern with simple and effectual means for raising and lowering the wick without the necessity of lifting the globe thereof.

To that end the invention consists essentially in the combination with a stationary oil-pot and burner supported thereon, of a wick-moving spindle passing through the burner and having one end projecting therefrom, a pinion secured to said projecting end, a circular rack mounted rotatably on the top of the oil-pot and engaging said pinion, and rack-rotating means including an operating member disposed below the oilpot.

The invention also consists in certain novel details of the construction and arrangement of the component parts of the mechanism for turning the wickraising spindle as will be hereinafter fully described and set forth in the claims.

In the accompanying drawings Figure 1 is a vertical sectional view of the lower portion of a lantern equipped with my wickraising device; Fig. 2 is an enlarged detail vertical section view showing the shaft and pinion for operating the gear which is disposed concentric with the rack and is connected thereto, and also showing the means for turning said shaft and for throwing the pinion thereof into and out of mesh with the gear; Fig. 3 is a detail plan view of the burner and attached ring formed with the circular rack; Fig. 4 is a transverse sectional view on the line -a"win Fig. 1; and Fig. 5 is a detail view showing the preferred construction of the thumb-piece for turning the vertical shaft and for drawing the same down to throw the pinion out of mesh with the gear.

In the drawings I have illustrated the well known so-called open-bottom lantern comprising the collar or ring 1 to which is secured the usual wire guard or frame -2 and base consisting of wires -33 and ring 4.

5- denotes the globe which is seated on the top of the collar -1 in the usual mancumferential flange 7 at its bottom which flange is formed with an upwardly projecting rim 8- embracing the lower portion of the collar 1-.

Any of the well known devices may be employed for securing the oil-pot detachably in the collar. To the top of the said oil-pot is applied the usual burner 9 which may be attached in any suitable manner which will permit it to be conveniently removed.

10 represents the wick which passes through the usual flattened upright tube ll of the burner.

In the present instance I have shown the opening of the oil-pot having a bushing 12- which is soldered or otherwise secured therein. Said bushing is formed with a top flange 12 seated at the edge of the opening and is screw-threaded internally to receive a threaded nipple 13 fastened to the burner, said nipple being formed with an external peripheral flange 14- hearing upon the flange 12* of the bushing. The construction of this burner is immaterial to the present invention, however, I prefer to use that illustrated to afford a convenient application of my wick-raising device which will now be described.

15- denotes the usual shaft which extends transversely through the burner for moving the wick. To the projecting end of said shaft is secured a pinion 16 which meshes with a circular rack 17 supported rotatably below the pinion and disposed concentric with the oil-pot. This rack consists of a fiat sheet metal ring provided with uniformly spaced radial slots serving as teeth to engage the pinion as more clearly shown in Fig. 3. To the said circular rack -17 is fastened an internal gear l8- which rotates the same. This gear is formed preferably from a transversely corrugated sheet metal strip bent into the shape of a ring and is soldered or otherwise secured to the inner face of a downwardly projecting peripheral flange -19 on the flat metal ring on which the rack is formed. To rotatably support this flat ring I clamp its inner edge portion loosely between the burner 9 and the flange 14 on the nipple 13 as shown in Fig. l.

Extending vertically through the oil-pot 6-- is a rotatable shaft -20 which projects through the top and bottom thereof. To the upper end of said shaft is secured a pinion 21 which meshes with the internal gear 18, and to the lower end of the shaft is attached a thumb-piece 22- for turning the same. This vertical shaft is adapted to be raisedand lowered to permit the pinion 2l to be moved into and out of engagement with the gear l8. It is obvious that when the pinion and gear are out of mesh the wick will not be moved in the operation of unscrewing the burner. The pinion is held in mesh by means of a spiral-spring 23 disposed between said pinion and top of the oil-pot for forcing the shaft upward, by which action of the spring the thumb-piece 22 is caused to bear against the bottom of the oil-pot. The said thumb-piece consists preferably of a sheet metal plate which is of rectangular shape and is pivotally connected to the lower end of the shaft -20 as indicated at 24.

\Vhen the pinion is in mesh with the internal gear the plate 22 presents one of its longitudinal edges to the bottom of the oilpot as more clearly shown by full lines in Fig. 2. By making the plate in the described shape it acts as a cam when turned to present one of its ends to the bottom of the oil-pot whereby the shaft 20 is drawn down to shiftthe pinion 2l out of mesh with the said internal gear 18 for the purpose stated. I desire to employ a folded metal plate for this thumb-piece and provide the lower end of the shaft 20 with an enlargement formed with an eye and inserted in the fold of the plate, through which fold and intervening eye portion passes a pivotpin 25 as illustrated in Fig. 5.

It is obvious that when the thumb-piece is turned to relieve the spring from compression, the said spring will automatically force the shaft upward.

What I claim is:

1. In a lantern, the combination with the oil-pot and the burner, of a wick-raising device comprising a. shaft extending transversely through the burner, a pinion secured to said shaft, a rotatable circular rack encircling the burner and engaging the pinion, a rotary shaft supported by the oil-pot, a suitably supported gear actuated by the latter shaft for transmitting motion to the rack, and means for turning said latter shaft as set forth.

2. In a lantern, the combination with the burner, and the wick-raising shaft passing therethrough, of a pinion secured to said shaft, a ring supported rotatably on the burner and provided with a circular rack for actuating said pinion and provided with an internal gear below the rack, a pinion supported on the oil-pot and engaging said gear, and means for actuating the latter pinion as set forth.

8. In a lantern, the combination with a stationary oil-pot and the detachable burner thereon provided with a wick-raising shaft,

. of a pinion secured to said shaft, and a circular rack secured rotatably to the burner for actuating the pinion and removable with the burner, and means supported on the oilpot for rotating said rack as set forth.

4. In a lantern, the combination with a stationary oil-pot, the burner, and wickraising shaft, of a pinion secured to said shaft, a circular rack engaging the pinion, a gear fastened to the rack and disposed concentric therewith, a. suitably supported vertical rotary shaft by the oil-pot, a second pinion secured to the upper end of the vertical shaft and meshing with. said gear, and a thumb-piece secured to the lower end of said vertical shaft for turning the same as set forth,

5. In a lantern, the combination with a stationary oil-pot, the burner, and wickraising shaft, of a pinion secured to said shaft, a circular rack supported rotatably above the oil-pot for actuating said pinion, an internal gear fastened to and disposed concentric with the rack, a rotary shaft extending vertically through the oil-pot, a pinion secured to the upper end of the vertical shaft and meshing with the internal gear, and means on the lower end of the vertical shaft for turning the latter shaft as set forth.
