VTICK ADJUSTMENT FORE OIL-BURNERS.

"T all whom it may concern:

'Be it known that I, Jacoe SwALLow, a

.CltiZGD of the United States; residing at'Los 7 'Angeles, in the county ofLos Angelefs and *State of California, have invented new and useful Improvements in Tick 'Atl ustme nts. v "for Oil-Burners of whichthe'followlngis specification.

This invention relates to a wick adjustment for oil burners and particularly pertains to a device for adjusting cylindrical wicks in oil stoves, lamps, and the like.

In adjusting the cylindrical wicks in oil stoves and lamps by the mechanism now commonlyemployed, binding of the wick] occurs, especially when it is short, which inhibits its being readily raised and lowered and thereby prevents accurate adjustment and regulation of the flame.

It is the object of this invention to overcome the above difiiculty by providing a mechanism which will operate on opposite sides of the cylindrical wick casing so as to equalize strains thereon and to impart propelling movement to the wick and its casing in such manner as to completely obviate binding of the wick and permit ready adjustment thereof.

Another object is to provide a device of the above character adapted to be applied to the ordinary cylindrical wick type of stoves and lamps now in use without material alteration thereof.

Other objects will appear hereinafter.

The invention is illustrated in the accompanving drawings in which:

Figure 1 is a view of an oil stove in side elevation with parts broken away and showing the invention as applied. Fig. 2 is a plan view of same. Fig. 3 is a vertical section on the line 33 of Fig. 2. Fig. 4t is a plan view illustrating a modified form of the invention.

More specifically, 5 indicates the tank or oil receptacle of an ordinary oil stove having an upwardly extending top 6 and formed with a central cylindrical draft tube 7 which terminates above the top 6 and is surrounded by the usual perforated wick tube 8. The wick tube 8 extends into the tank 5 and is spaced from the cylinder 7 concentric therewith to form a space for the reception of the cylindrical or tubular wick 9.

The present invention resides in a means for raising and lowering the wick tube 8 Specification of Letters Patent.

and'the wick Q'therein, which means is constructed a s'follows: Extending into the top portion 6 of the tank 5 andarrangedhorizontally alongside of'the 'wickitube 8 is a shaft 10, fitted with a hand wheel 11 on its outer end and having a pair of spacedpinions 12 mounted thereon and disposed within the tank. The pinions 12 mesh with verticall'y alined perforations inthe wick tube 8'with the teeth of the pinions extending through the perforations into engagement with the wick '9. The shaft may be mounted in anysuitable'bearings,being here shown as extending through a tube 13 where itpasses through the wall of the top portion G'of the tank and is seated at its inner end in a bracket 14, as particularly shown in Fig. 1. Mounted in suitable bearings and extending parallel with the shaft 10 on the opposite side of the wick tube 8 is a short shaft 15 which is fitted with a pair of pinions 16. The pinions 16 engage the perforations in the wick tube 8 with their teeth engaging the wick 9 diametrically opposite the point of engagement of the pinions l2 therewith. The shaft 15 is designed to be rotated simultaneously with the shaft 10, only in opposite directions thereto. For this purpose the shaft 15 is geared to the shaft 10 so that when the latter is revolved the shaft 15 will be rotated in unison therewith.

The geared connections between the shafts 10 and 15 comprise a spur pinion 17 mounted .on the shaft 10 which mesh with an idler gear 18 which in turn meshes with a. second idler gear 19 meshing with a pinion 20 on the shaft 15. The gears 18 and 19 are mounted in suitable hearings on the outer face of the top portion 6 of the tank, as particularly shown in Figs. 1 and 2, and are preferably arranged intermediate the hand wheel 11 and the pinions 12 on the shaft 10.

In the modified form of the invention shown in Fig. 4, the shafts 10 and 15 are elongated to extend through the top portion of the tank 5 to receive the gears through which shafts 10 and 15 are revolubly connected together on the outer ends thereof. This latter arrangement is employed where it is impractical to provide an end support for the shafts 10 and 15 within the tank.

In this case the shafts 10 and 15 extend through bearings formed in the upwardly projecting portion of the top tank. The

pinions 17 and 20 are of corresponding diameter and the idler gears 18 and 19 correspond to each other so that when the shaft 10 is rotated the shaft 15 will be revolved therewith at a corresponding speed but in the opposite direction.

In the operation of the invention rotation of the shaft 10 operates through the pinions 17, gears 18 and 19, and pinion 20, to rotate the shaft 15, as just described. The rotation of the shafts l0 and 15 operate through the pinions 12 and 16 to advance or retract the wick casing 8 and wick 9. Equal strains are thus brought to bear on diametrically opposite sides of the wick tube 8 which serves to move the tube 9 longitudinally evenly throughout its length, thus obviating binding of the wickand permitting readv and accurate adjustment thereof.

What I claim is: j a

The combination with an oil stove tank formed with an upwardly extending top,

and a vertically reciprocal perforated wicktube extending through the top of said tank adapted to encircle a wick, of a pair of parallel tubular bearings projecting horizontallythrough the tank top, a pair of shafts in said bearings extending into the tank, pinions on each of said shafts engaging the wick-tube on diametrically opposite sides thereof, a spur pinion on each of the shafts adjacent the outer ends of the tubular bearings, a pair of intermeshing idler pinions meshing with said spur pinions bearings for said idler pinions on the outer face of the tank top, and a hand wheel on one of said shafts.

In witness that I claim the foregoing I have hereunto subscribed my name this 22nd day of March, 1915.

JACOB SWALLOIV.
