LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 360,984. dated April 12, 1887. I 'I vApplication tiled August 10, 1886. Serial No. 210,530. (No model.)

To all whom it may concern.-

Beit known that I, LEwIs J ArwocD, of Vaterbury, in the county of New Haven and State of Connecticut, have invented an Improvement in Lamp-Burners, of which the following is a specification.

This invention is made with reference to that classof burners in whichV two wicks are employed and in which the chimney-holder is adapted to being raised or lowered.

In my improvement the. slide-rods that support the chimney-holder are between the two wick-tubes, and slide through openings in the ratchet-cap and burner-base, and the spring that supports the slide rods and chimneyholder is nearly straight and passes across the middle of the burner above the air-distributer, and its ends are firmly fastened to the burnershell, so that the springcannot become detached or injured, and there is a pusher to unlatch the spring from the slide-rods to allow the burner to descend.

In the drawings, Figure 1 is a vertical section of the burner with the chimney-holderin an elevated position. Fig.v 2 is a plan view 0f the parts below the line m w. Fig. 3 is an inverted plan of the globe-holder and parts connected therewith; and Fig. 4 isan elevation of the sliderods, part of their supportingspring and the bridle-piece detached.

The base of the burner is made as a screw, 2, and above the same the metal spreads outwardly, and is perforated at 3 for the passage of air, and at 4L is the top flange of the base, anda rim, 5, around it.

The ratchetcap 6 covers the ywick-raisers 7 and 8, and it is perforated for the passage of the tubes 9 and 10 for the wicks, and 1l is a foraminous air-distributer resting on the flange 4,andthese parts are all permanently connected together. Y

The chimney-holder 15 is usually made with springs to grasp the base of the chimney, and within the same is the deflector 16, with flameslots above the wick-tubes, and around the chimney-holder is an open gallery, 17, for the shade or globe, and the inwardly-projecting arms 18 are fastened at their outer ends below the gallery and at their 'inner ends to the ver-A tical sliding guide-rods 20, that pass through holes in the air-distributer, the ratchet-cap, and the burnerbase, and at their lower ends there are projections or heads that prevent the chimney-holder being raised too high.

There is a spring, 21, crossing over the airdistributer between the two wick-tubes, and the ends are bent at right angles and riveted to the inner surfaces of the rim 5, and this spring presses against the sliding guide-rods 20 at one side thereof, so as to spring into the notches in such guide-rods and hold up the chimney-holder when it is elevated above the tops of the wick-tubes; y

In order to lower the chimney-holder there is a bridle-piece, 25, attached to the spring and passing around one of the wick-tubes to near the inner surface of the rim 5, and the push-pin 26, passing in through a hole in the rim, is attached to the bridlepiece, and by these the spring is pushed back to unlatch the sliding guide rods and allow the chimneyholder to be lowered.

The parts are compact and strong and are not liable to become bent in use, and the wicks h are easily trimmed or lighted.

When the chimney-holder and gallery are lowered, the latter rests upon the top of the rim 5, as seen in dotted lines, Fig. 1.

I am aware that the chimney-holder has been held upon sliding guide-rods passing through the burner-base'and ratchet-cap, as in the patent No. 34,065, to T. Mayhew, and also that a revolving nut has been used to raise and lower the rods and chimney-holder, and that springs have been employed for sustaining the chimney-holder when elevated. In my improvements the spring, being nearly straight and attached at its ends to the burner, is not liable to be bent or injured, and is much less expensive to manufacture than the devices heretofore employed, and the parts are simple and durable.

I claim as my invention-'- 1. The combination, with the burner-base having the screw and perforated portion, and the ratchet-cap and air-distributer and the two wickftubes passing through the base, lratchetcap, and air-distributer, of vertical guide-rods passing in between the two wick-tubes down through the air-distributer, ratchet-cap, and

rco

burner-basc, and the chimney-holder fastened to the upper ends of the guide-rods, and a spring-catch attached at both ends to the burner and acting to hold the guide-rods when ele- 5 Vated, and a pusher and forked bridle passing at each edge of one of the wick-tubes and attached at its ends to the spring, substantially as set forth.

2. The combination, in a lamp-burner, of [o two wick-tubes7 a burner-base with a rim at its upper edge, a ratchet-cap and air-distributer, two vertical guido-rods passing down through the ratchet-cap and burner-base, and a chimney-holder attached to the guide-rods, and a I 5 deflector carried by the same, a nearly-straight spring passing across the burner between the wick-tubes and attached at its ends to the rim and pressing against the sides of the guiderods7 and a pusher to move the spring, sub- 2o stantially as set forth.

3. The combination, in a lamp-burner, of two wick-tubes, a burner-base, a ratchet-cap and air-distributer, two vertical notched guiderods passing down through the ratchet-cap and burner-base, and a chimney-holder sup- 25 ported by the guide-rods and a deiector carried by the same, a nearly-straight spring passing across the burner between the wick-tubes and attached at its ends to the burner-she117 and pressing against the sides of the guidc- 5o rods, and a pusher to unlatch thc spring, substantially as set forth.

Signed by me this 5th day of August, 1886.
