LANTERN ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. L11,218, dated September 17, 1889. Application filed January 8, 1889. Serial No. 295,738. (No model.)

To (tZZ whom it may concern.-

Be it known that 1, JOHN WILLIAM FEENY, of Elmira, in the county of Ohemung and State of New York, have invented a newand Improved Lantern Attachment, of which the following is a full, clear, and exact descrip- It frequently happens that lantern-wicks become crusted, and hence give a feeble light, so that at times when a signal is required it cannot be given, as it is impossible to correct the difficulty except by turning up the wick, and this cannot be done in gusty, windy weather, as with the ordinary form of lantern the oil tank or receptacle has to be removed from the globe-holding frame in order to reach the wick-raising spindle, and in so removing the tank the light is liable to be extinguished. his to obviate this difficulty and to providefor the adjustment of the wick that I have designed the attachment forming the subject-matter of this application, said attachment consisting, essentially, of a rack arranged for connection with the base of alantern and a toothed disk or wheel arranged for connection with the wick-raisin g spindle, said toothed disk or wheel being adapted to engage the rack, so that as the oil tank or receptacle is turned a rotary motion will be imparted to the wick-raising spindle, and the wick will thus be adjusted to such position as maybe desired.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a cross-sectional View of a portion of a lantern, representing the same as it appears when provided with my improved attachment. .Fig. 2 is a plan view of the lantern, the globe being removed and the frame being shown in section; and Fig. 3 is a cross-sectional view on line a: (r of Fig. 1.

In the drawings, 10 represents the base of an ordinary lantern, 11 the oil tank or receptacle, and 12 the wick-raising spindle. To the base 10 there is connected a circular plate'l l, provided with inwardly-extending teeth a, which constitute a rack, the plate .said spindle is provided with a toothed disk or wheel 16, the teeth of said disk or wheel being so proportioned as to engage the teeth a of the plate 14, so that if the tank or receptacle 11 be turned, as indicated by the arrow shown in Fig. 2, the wick-raising spin.- dle will be turned in the directionof its ar row and the wick will be raised, a lowering of the wick being brought about by turning the tank 11 in the opposite direction, this movement of the spindle 12 being brought about by reason of the fact that as the receptacle .or tank 11 is turned, as above described, the teeth of the wheel or disk 16 will engage the teeth a, and a rotary motion will consequently be imparted to the disk or wheel and to the spindle to which the disk or wheel is rigidly connected.

By means of this attachment the wick may be raised or lowered so as to vary the intensity of the light at will, and as the rack holds the wick-raising spindle from turning a loose- 'littin g wick which is not liable to crust may be employed. This a-ttaclnnent does not interfere with the manipulation of the wick in the old way.

It will be noticed that the teeth a project inwardly and are separated by slots open at their inner ends, and therefore, when the wick has been properly adjusted, as in Fig. 1., the receptacle may be tilted to the right at its upper end until the teeth of the wheel 16 are out of mesh with the teeth a and then rotated until the wheel passes the teeth a, when the receptacle may be allowed to again assume a vertical position. This disconnection of the gearing prevents the accidental turning of the wick when the lantern is swung, for in this class of lanterns the springs yield sufficiently to allow the receptacle to move axially at times. This disconnection of the gearing may be effected without removing the oil-receptacle.

The improvement may readily be applied to the lanterns now in use.
