WlCK-RAISING MECHANlSM.

SPECIFICATION forming part of Letters Patent No. 366,805, dated July 19, 1887. Application tiled February 4 1887. Serial No. 126,5l2. (No model.)

To all whom it may concern.-

Beit known that I, GEORGE W.Wo01)wARD, of Brooklyn, in Kings county and State of New York, have invented a certain new and useful Improvementin ick-Raising Mechanisms for Lamps, of which the following is a specification.

This improvement relates to central-draft lamps; and it consists in the combination, with a wick, of a wick-ring secured thereto, a rod provided with a hand-piece above the lamprcservoir, a bearing in the reservoir which receives but does not engage the rod, said rod and ring being provided, the one with a projection and the other with a pair of shoulders for engaging therewith.

In the accompanying drawings, Figure 1 is a vertical section of a portion of a centraldraft lamp provided with an Argand burner, and embodying my improvement. Fig. 2 is a view illustrating a modification of' my improvement.

Similar letters of reference designate corresponding parts in both the figures.

A A designate the wick-tube of the lamp. The wick-tube consists of two cylindric shells of metal, A A, arranged one within the other concentrically thereto and at such a distance therefrom as to leave a space for a hollow cylindrical ring, 13.

The wick B may be of any suitable construction and material. In the drawings I have intended to represent one of ordinary construc tion and material.

The inner shell, A, of the wick-tube may be a part of the lamp-reservoir and extend entirely through the same. In such case it will be open at the bottom, so that air may pass upwardly through it.

The outer shell, A, of the wick-tube will not extend to the bottom of the reservoir, but will terminate some distance above the same, so that it will leave the lower part of the wick exposed to the oil in the reservoir.

There may be combined with the wick-tube aindistribnters or draft-plates and deflectors in the usual or any suitable manner.

I have shown the upper part of the inner shell of the wick-tube as receiving within it a perforated metal thimble, which extends above the same.

It is immaterial, so far as my present improvement is concerned, what the appurtenances of the wick-tube shall be, as this improvement relates tothe mechanism for ad j usting the wick.

The wickadjusting mechanism consists of a ring, 0, (here shown in the form of a tube,) to which the-wick is attached. As shown, the ring surrounds thewick externally. The wick may be secured to this ring by sewing, or by means of prongs, with which the ring is pro vided. This ringin effect constitutes a wickcarrier, for motion is transmitted to it for the purpose of adjusting the wick.

The means employed to adjust the r111 .0 consist, as here shown, of a rod, D, fitted to a guide in the lampreservoir, so as to be capable of being reciprocated or moved lengthwise in a vertical direction. Its upper end extends through the top of the reservoir, and is provided with a handle which can be conveniently grasped by the hand. The rod does not engage the guide, and it will be seen that below the hand-piece it is substantially the same size, so that it will slide readily through the guide.

The rod D is not permanently connected to the ringO, but is only detachably secured to the latter. Owing to this the ring 0 may be disengaged from the rod, so that it may with the wick B be removed from the lamp without necessitating the removal of the rod. This affords convenience for wicking or substituting in the lamp a new wick for an old one.

Various securing devices may be employed for detachably connecting the ring 0 and rod D. In Fig. 1 I have shown the rod D as provided with a ring, d,'at the lower end. This ring d is adapted to receive within it the ring C, and to engage with the latter when the latter is turned within it. The engagement may be effected by means of screw-threads, or in any other suitable manner. Among other means for effecting the engagement of the rings I may suggest a bayonet-joint, such as I have illustrated in this figure.

Still another illustration of a means of connecting the rod D detachably to the ring 0 is given in Fig. 2. Here the ring 0 is provided with a circumferential-flange, 0, which projeets slightly outward, and the rod D pro vided with an upturned end which is notched at (1 opposite the flange c of the ring 0. The flange c of the ring has a notch, 0', extending vertically through it. \Vhen the ring is adjusted into such position that the notch c of its flange is brought opposite the upturned end of the rod 1), the ring may he slipped downwardly, so as to cause its flange c to occupy a position horizontally in line with the notch d in the upturned end of the rod D. If the ring be rotated so as to bring the notch c of its flange 0 out of line with the notch d in the upturned 'end of the rod D, the rod and ring will be locked together. 1

In both examples of myimprovement shown a projection on the ring engages apair of shoulders on the rod or its appurtenances. Obviously the projection might be on the rod and the jaws on the ring.

I do not herein lay claim to a central-draft lamp provided with awick-raising ring or analogous device surrounding the central-dratt tube, and a rod extending through a guide in the top of the lamp-reservoir, said ring and rod being provided, the one with atongue and the other with a loop.

2 r V I 366805 I do not herein lay claim to the combination, in a central-draft lamp, of a wick, a wick-ring secured thereto, a rod provided with a handpiece above thelamp-reservoir and detachably secured to the ring, and a bearing in the lampreservoir which receives but does not engage the rod, said rod below the hand-piece being substantially the same size, so that the rod may slide longitudinallythrough the bearing, as I intend to make thesame the subject of another application for Letters Patent, and I hereby reserve to myself the right so to do.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination, witha central-draft lamp,

of a wick-ring, a rod provided with a handpiece above the lamp-reservoir, a bearing in the reservoir which receives but does'not en- GEORGE W. WOODVVARD.
