WICK RAISING OR LOWERINGATTACHMENT FOR BURNERS.

SPECIFICATION forming part of Letters Patent No. 634,762, dated October 10, 1899.

Application filed April 22, 1899.

T all whom it may concern- Beit known that I, ROBERT WELSH MCFAR- LAND, of Paulton, in the county of Westmoreland and State of Pennsylvania, have invented a new and Improved Wick Raising or Lowering Attachment for Burners, of which the following is a full, clear, and exact description;

The obj ect of my invention is to provide a wick raising and lowering attachment especially adapted for use upon lanterns capable of being operated from the bottom of the lantern and which in addition to being very simple and economic will in no manner interfere with the manipulation of the burner.

Another object of the invention is to so construct the wick vraising and lowering attachment to the'lantern and apply it to the wick spindle or burner that even under exceedingly rough usage the attachment will remain in perfect working order.

The invention consists in the novel conf struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of referenceindicate corresponding parts in all the gures.

Figure 1 is a side elevation of the lower portion of a lantern, parts being broken away,

and a side elevation of the improved wick raising and lowering device appliedl thereto,

. the said attachment being in position to raise l Fig. 2 is a plan view of the oil-receptacle of the lantern and a partial 1 and lower the wick,

the position it assumes when disconnected from the wick-spindle of the burner. Fig. 4l:

to the upper portion of the base of the lantern. A represents the oil-receptacle of a lantern B, the base; C, a guard, and C the burner,

which is provided with the usual wick-spindle v Fig. 3 is a-partial plan view of the oil-receptacle,.the view being on an en larged scale, illustrating the attachment in serai No. 714,033. ci@ moda.)

; but a pinion 11 is securedto said spindle under surface of the upper portion of the base a guide-plate 13 is located, being attached by solder, rivets, orequivalent means, and said guide-plate is provided with a transverse guide-slot 14, extending through one of its edges, and said slot is narrower than the' aperture 12, but .is located immediately below lsaid aperture, as shown best in Fig. l.

A bracket D is secured to the top portion ofthe oil-receptacle A, adjacent to the wick- `spindle 10. This bracket D preferably consists of a horizontal or base member 15 and a vertical member 1G at the inner-longitudinal edge of the vbase member. The vertical mem- .ber 16 of the bracket is provided at the end farthest removed from the Wickspindle with ,an angle-lip 16, that extends inwardly beyond the inner face of the verticalmember'of the bracket and upwardly, as is best shown in Figs. 2 and 3, and the vertical member 16 of the bracket is also provided with a longitudinal opening 17, as is best shown in Fig. 4, adapted to receive a keeper to loe hereinafter described. Y

A latch 1S inthe form of a lever is pivoted upon the inner face of the vertical member 16 of the bracket, at the end nearest the wickspindle, and said latch-lever is provided with a downwardly-extending finger 19, a portion of the linger being adapted to cross the open- :ing 17 in the member 16 or" the bracket when the handle end of the latch-lever is held between-the lip 16 and the bracket member 16, as shown in Fig. 4.

at the outer end of its base member tothe base 15 of the bracket D, at that end adjacent .to the lip 16, and the upper. portion of the hanger 2O is so constructed that it will readily receive the pinion 11 on the wick-spindle 10. A shaft 21 is journaled in the upper member of the swinging hanger 20, and at the upper end of said shaft a worm .22 is formed, adapted for engagement with the pinion 11 ot' the wiek-I spiudle when the bracket is swunginward and the wick is to be raised and lowered from the bottom of the lantern. The shaft 2l passes downward through a guide depression 22a,

A hanger 20, usually of S form, 1s pivoted f ICO made in the side of the upper portion of the oil-receptacle; but said depression is not absolutely necessary, since a guide-pin 23 is preferably located adjacent to the depression, which guide-pin is adapted for engagement with the shaft 2l when the worm 22 on the shaft is in mesh with the pinion l1 on the wickspindle. An inwardly-extending tongue 24 is attached to the lower member of the hanger, and this tongue serves as a keeper and when the worm and pinion are in engagement eX- tends through the opening 17 in the member 16, as shown in Figs. 2 and 4. This keeper is provided at its inner end with a slot 25 in its side edge, said slot being adapted to receive the nger 19 of the latch-lever 18 when the latter is in locking position. Under this construction it is obvious that the latch-lever and keeper when brought in their lockingre-v lation effcctually prevent the worm 22 from leaving the pinion ll on the wiek-spindle, but that at any time desired when the latch-lever is disconnected from the keeper 24 the hanger 20 may be swung outward and in a manner to carry the worm 22 out of engagement with the pinion ll on the wick-spindle, thus permitting the burner to be unscrewed from the oil-receptacle. This position of the attachment is shown in Fig. 3. The lower portion 0f the shaft 2l is passed through the aperture or opening l2 in the base, and just below this aperture in the base the shaft is provided with a reduced section 2G, and this reduced section has play in the slot 14 of the guideplate 13, as shown in Fig. l, and a suitable hand-wheel 27 or its equivalent is attached to the lower end of the shaft, being concealed by the bow or bottoni portion of the buse B. Thus it will be observed that the shaft 2l may be readily swung outward when the hanger 20 is carried in the same direction, and, furthermore, it is obvious that when the worm 22 is in engagement with the pinion l1 on the wick-spindle the wick maybe raised and lowered by simply turning the hand-wheel or head 27 of the shaft 2l in a proper direction.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A wick raising and lowering attach ment for burners of lanterns and the like consisting of a swinging hanger, a shaft secured to and depending from said hanger and having its lower end loosely mounted in the base of the lautern, and a locking device for said hanger, as set forth.

2. A wick raising and lowering attachment for burners, comprising a swinging hanger having a section arranged to receive the head of a wick-spindle, a bracket upon which the hanger is mounted, a keeper upon the hanger, adapted to pass through the bracket, a latch carried by the bracket and arranged to engage said keeper, and a shaft carried by the hanger, provided with a gear arranged for engagement with the head of the wick-spindle of the burner, as specified. f

8. The combination, with the base and oil receptacle of a lantern, its burner and wiekspindle, said spindle being provided with a pinion, of a hanger mounted to swing upon the burner, having a section prepared to receive the pinion of the wick-spindle, a locking device for the hanger, a shaft, one end of which is mounted in the hanger the other end being loosely mounted in the base of the lantern, and a gear carried by the shaft, adapted to engage with the pinion of the wick-spindle, for the purpose set forth.

4. The combination, with the base, oil-receptacle and burner of a lantern, together with the wick-spindle of the burner and a gear secured upon said spindle, of a bracket attached to the oil-receptacle, provided with an opening therein, a latchlever pivoted upon the said bracket and provided with a finger extending across the opening therein, means for locking the said latch lever, a hanger pivoted upon said bracket, having a portion prepared to receive the pinion of the wick-spindle, a keepercarried by the hanger and arranged to enter the opening in the bracket and to be engaged by the finger of the latchlever, a shaft loosely mounted in the base of the lantern, means for turning said shaft from its lower portion, and a gear carried by the shaft and adapted for engagement with said pinion, as described.

5. The combination with a lantern having a wick-spindle and a pinion on' said spindle, of ahanger mounted to swing in a horizontal plane on said lantern and having a shaft mounted therein, said shaft depending from said hanger alongside the lantern and having a gear arranged to be brought into and out of engagement with the pinion when the hanger is swung, means for locking the hanger, and guides on the lanterns and adapted to receive the shaft, as set forth.

6. The combination with a lantern having a wick-spindle and a pinion on said spindle, of an angular bracket secured to said lantern and having a lip at one end and an opening in its vertical member, a swinging hanger mounted on said bracket and provided with a keeper adapted to enter said opening, a latch pivoted on said bracket, the said latch being formed with a finger adapted to engage said keeper when its free end is received in the said lip, and a shaft secured to and depending froin said hanger and having a gear adapted to mesh with the said pinion, as and for the purpose set forth.
