WICK -TUBE FOR LAM PS OR OIL -STOVES.

SPECIFICATION forming part of Letters Patent No. 445,789,dated February 3, 1 891.

Application filed February 24, 1890 Serial No, 341,539. (No model.)

to to which it appertains to make and use the same, reference being had to the accompanying draw1ngs,wlnch form a part of this specification.

l\Iy invention relates to a new and useful I improvement in wick-tubes for lamps or oilstoves; and it consists of the devices and appliances hereinafter specified and claimed, and illustrated in the accompanying drawings, in which- K Figure 1 is a longitudinal vertical section through the head of the wick-raiser and adjacent parts. Fig. 2 is an end elevation looking toward the recessed plate, the head being removed from the shaft. Fig. 3 is a vertical cross-section on the line 0cm, Fig. 4, and Fig. 4

is a plan view with the cap removed.

The objects of my invention are to provide an improvement in wick-tubes, whereby greater perfection shall be attained, together 0 with greater simplicity, durability, and econ: omy of construction, and which shall avoid liability of getting out of order.

I carry out my invention as follows:

A represents any desired base or support 5 for the wick-tube. It may consist of a suitable portion of a lamp-fixture or burner or constitute a portion of an oil-stove.

For purposes of explanation I will describe my invention as applied to an oil-stove, and

in which case A may represent the stoveplate, through which the usual wick is projected.

B is the wick-raiser, and O the bearingspindle. The completed wick-raiser and bear- 5 ingspindle may be essentially of ordinary form and construction.

Instead of journaling the wick-raiser and spindle in a stamped sheet of metal housing at one side of the wick-tube, as has heretofore been common, I provide supporting end walls or brackets D I), provided with any suitable journal-bearings or perforations, one or both of which are removably engaged upon the base A in a ready manner, as by a screw D fastening the same upon the base. It will be apparent that one end wall or bracket can be secured upon the base and one end of the shaft of the Wick-raiser B and the spindle C, respectively, be engaged therein. The supporting wall or bracket for the opposite ends of said shaft and spindle may then be engaged therewith, when it, too, may be fastened upon the base in the same manner as the other bracket, as bya screw D As so constructed and arranged, it is evident that the toothed disks 1) on the wick-raiser shaft and the bearing-disks c on the bearing-spindle may be located in place and permanently secured upon said shaft and spindle, respectively, before the same are engaged in said end walls or brackets. Ileretofore, as is well known, it has been necessary, first to engage said shafts and spindles in the bearings of stamped sheetmetal housings before the said disks, respectively, could be located and fastened in place, renderin g the operation less easily and readily accomplished than where, as contemplated by my invention, this work can all be completed before the engagement of the said shaft and spindle in the end walls or brackets.

E represents a cap or housing, which may be separabl y engaged over the wick-raiser and bearing-spindle. I do not limit myself to any specific construction of this cap or housing. As shown, it is constructed with a wick-tube at E, and with flanges e to support the customary perforated plate E It is also shown so made as to be readilyslipped over the wickraiser and bearing-spindle, resting upon the upper edges of the end brackets, making a close housing. At "the base the cap is provided with flanges 6', through which it may be secured upon the base A, as by screws 6 Instead of making both end walls or brackets removably engaged upon'the base, one of 5 them might have afixed engagement thereupon, if preferred,without departing from my invention. So, also, one of the end walls or brackets might be made integral with the cap or housing E without departing from my invention. The wick-raiser and bearing-spindle so arranged will of course operate effectually so far as they are alone concern ed with-' out the cap. A great advantage of this construction and arrangement consists in the fact that the wick-raiser shaft and bearing- 5 spindle will always be the same distance apart or parallel with each other. \Vhere said shaft and spindle are located, respectively, in separate stamped sheet'metal housings, as has been common heretofore, there to has been found a liability that the housings will be unevenly stamped, or that they may be unevenly secured together at the ends, so that the said shaft and spindle will vary in the distance from each other at the ends, ren-' I I5 dering them untrue, and the working of the wick consequently untrue. By my invention, however, any such liability is effectually and completely prevented, the working of the wick being always true at both edges. In Figs. 1. and et I have shown a simple and efficient device for regulating the operation of the wick-raiser.

I'Ieretofore, as far as I am aware; there has been much liability in turning down the wick of turning it down too far and disengaging it from the wick-raiser altogether. To prevent this one end of the wick-raiser shaft is provided with a recessed plate F, which may have recesses 01' perforations f passing through the 0 plate and with recesses more limited in extent, the same entering the plate, as shown at f. The recesses f f are preferably located in alternate order, as shown.

G represents a loose head mounted upon 5 the outer end of the wick-raiser shaft, and provided with a stud 9, adapted to engage in said recesses. The head, bein gloosel y mounted upon said shaft, may be turned back and forth to engage the stud thereof with any de- 40 sired recess in the adjacent plate F. The shaft is also provided with a spring II, which may be engaged thereupon by a washer II, riveted upon the shaft, the arrangement being such as to give a spring-tension to the 5 head G to hold it in any adjusted position. The head is also constructed with a shank or shoulder G, from which the stud projects, said shoulder adapted to strike upon the edge of the base A, as illustrated in Fig. 4, when the stud is located in the perforationsf of the plate F, and to clear the said edge when the stud is located in the recesses f" of said plate. It will be evident that when the stud is engaged in one of the perforations f the head will move inward on the shaft, so as to permit only a partial rotation of the shaft, as the shoulder G will limit the rotation of the shaft when thrown over in either direction against the edge of the base; but if the stud 6c enters one of the recesses f the head will be prevented from moving inward, and will then clear the edge of the base and permit a complete rotation of the shaft.

1 The advantages of this device are evident.

By adjusting the post in one of the perforations f the wick can only be turned down until the shank strikes the base, and it can be turned up until the shank strikes the base in the opposite direction. If morewick is desired to be turned up, as when the end has been burned off,the head may be pulled out, disengaging the stud from one of the perforationsf, when the head may be turned over, engaging the stud in 7 one of the recesses f. The wick may then be manipulated as desired,after which the stud may be re-engaged with one of the perforationsf, again limiting the movement of the wick.

I do not limit myself to the employment of the bearing-spindle in connection with the wick-raiser, as it is evident that it is not indispensable. The cap might,if desired,be so constructed as to form a bearing for the wickraiser. This construction also enables me to provide the wick-raiser and bearing-shaft with. gears, as at Q, inside the end walls, if desired.

\Vhat I claim as my invention is 1. The combination, with a base, of sepa rate end walls united thereupon and a wickraiser journaled in said end walls, substantially as set forth.

2. The combination, with a base, of separate end walls united thereupon, a wick-raiser, and bearing-spindle journaled in said walls, said wickraiser and bearing-spindle geared together inside said end walls, substantially as set forth.

3. The combination, with a base, of separate end walls and a wick-raiser journaled therein, one of said walls having a separable engagement with said base, substantially as set forth.

4. The combination, with a base, of separate end walls united to said base, a wickraiser journaled in said end walls, and a cap E, independent of and removable from said end walls, substantially as set forth.

5. The combination, with the wick-raiser, of a recessed plate rigidly engaged thereupon and an operating-head, with a shank G, and provided with a stud loosely engaged with the recessed plate, substantially as set forth.

6. The combination, with a base, of a wickraiser located thereupon, said wick-raiser havin g, in combination therewith, a recessed plate rigidly secu red thereto, and an adjustable operating-head provided with a shank G and a stud g to engage said recessed plate, said operating-head arranged to clear the base when adjusted for that purpose, and vice versa, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
