W ICK-RAISING MECHANISM FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 440,683, dated November 18, 1890.

Application filed March 27, 1890. Serial No. 345,584. (No model.)

To aZZ whom it may concern: 7

Be it known that I, GEORGE W. 700D- WARD, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Vick- Raising Mechanism for Lamps, of which the following is a specification.

My improvement relates to wick-raisers for lamps of the kind generally known as Argand lamps. In this type of lamps it is common to employ a band or ring of sheet metal surrounding and gripping the wick, and such a device is usually adjusted by means of a rod having its upper end extended through the top of the reservoir. To facilitate the removal of the band or ring for rewicking the lamp, provision has been made for the detachment of the band or ring from the rod.

My improvement relates to a detachable band or ring and rod of the kind above mentioned; and the object of the improvement is to provide a more desirable connection be tween such parts.

The improvement consists in the combination of arod having its lower end bent upward and tapered and notched and a band or ring having a spring-clip attached to it for engaging with the notched portion of the rod.

In the accompanying drawings, Figurel is a perspective view of a wick band or ring and adjusting-rod. Fig. 2 is a similar view showing the parts detached. Fig. 3 is a horizontal section taken at the plane of the dotted line 0000, Fig. 1. Fig. 4C isa view similar to Fig. 1, but illustrating a modification.

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

A designates a wick band or ring. It may be made of any desired constructionas, for instance, of sheet metal slitted and punched to provide surfaces that will engage with a wick.

B designates a rod for adjusting the band or ring A with the wick. This rod may be of any suitable shape. As here shown, it is a round rod having a bendat the lower portion and the extremitybturned upward par- In the upturned extremity I) is a transverse notch b. The

the wick-tube, together with the outer-air distributer and chimney-gallery, may be removed. This construction is so well known as not to require illustration.

O designates a spring-clip with which the band or ring A is provided. As here shown, this spring-clip is made of a strip of metal attached to the band or ring and near. the lower end thereof, so as to extend in the direction of the circumference of the same. It is of a width to en gage the notch b of the rod B. This clip is bent in the direction of its length outward, then in the direction of the circumference of the band or ring, and then toward the band or ring, so as to form a looplike portion 0. The free extremity is bent outward, so that it may be easily grasped by the hand for the purpose of pulling the clip outward. The extremity of the upturned portion of the rod 13 is pointed or tapered. This facilitates its insertion in the loop-like portion of the clip from the lower edge of the clip. When the rod is so formed, it 11" ay be engaged with the clip by an upward move ment of the rod after the upturned extremity has been entered in the loop-like portion of the clip, or by a downward movement of the band or ring after the entrance of the upturned extremity of the rod into the looplike portion of the clip. The band or ring may be unfastened from the rod by simply pulling out the free extremity of the clip. When the upturned extremity of the rod is made round, provision is afforded for arocking or oscillating movement of the rod relatively to the band or ring or of the latter relatively to the rod, and this will sometimes prove a convenience in engaging and disengaging the rod and band or ring. When the main portion of the rod is made round, the rod may, after disengagement from the band or ring, be oscillated, so as to move the upturned extremity far away from the band or ring to facilitate the removal and reinsertion of the band or ring with an attached wick.

In Fig. 4 I have shown the clip 0 some- What elevated above the lower portion of the band or ring and have represented the band or ring as provided at its lower portion with a loop D. The upturned end of the rod B is intended to pass freely through the loop and is notched near its upper end, but only throughout a portion of its length sufficient to engage with the clip. The addition of the loop reduces the liability of any rocking of the band or ring or rod.

By my improvement a very simple, cheap, and secure fastening for the band or ring and rod is provided.

It will be observed that the fastening consists, generally considered, of a projection upon one part and a pair of shoulders upon the other part, the shoulders being the portions of the rod above and below the notch which is formed therein, and the projection being'the clip which projects into the notch.

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

1. The combination of a wick band or ring, a rod provided with an upwardly-extended projection or end tapered and transversely notched, and a spring-clip attached to the band or ring and engaging said notch, sub stantially as specified.

2. The combination of a wick band or ring, a rod provided with an upwardly-extended projection or end transversely notched and upwardly tapered, and a spring-clip attached to the band or ring and engaging said notch, substantially as specified.

3. The combination of a wick band or ring "having a loop-like portion, a rod provided with an upwardly-extended projection or end transversely notched and upwardly tapered, and a clip attached to the band or ring and engaging said notch, substantially as specified.

4. The combination of a Wick band or ring provided with a loop-like portion and an upwardly-turned free extremity, a rod provided with an upwardly-extended projection or end transversely notched and upwardly tapered above the notch, and a clip attached to the band or ring and engaging said notch, substantially as specified.

5. The combination of a wick band or ring, a rod provided with an upwardly-extended projection or end transversely notched and upwardly tapered above the notch, a loop on said band or ring for receiving the upwardly. extended projection or end, and a clip attached to the band or ring and engaging said notch, substantially as specified.
