AC ETYLEN E-GAS LAM P.

SPECIFICATION: forming part of Letters Iatent No. 650,854, dated June 5, 1900. Application filed January 13, 19Q0. Serial No. 1,262. (No model.)

To aZZ whom it 17mg concern:

Be it known that I, ARTHUR K. MILLER, a citizen of the United States, residing at Waterbury, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Acetylene-Gas Lamps, of which the following is a specification.

One object of my invention is to provide improved means for feeding water to calcic carbid, to the end that the feeding of water can be conveniently regulated in accordance with the quantity of gas to be evolved.

Another object of the invention is to provide an improved construction of acetylenegas lamp particularly adapted for useon vehicles.

The invention also consists in the novel de-' tails of improvement that'will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein Figure 1 is a plan view of a lamp embodying my improvements, the cover being removed. Fig. 2 is a partly-sectional side elevation thereof, and Fig. 3 is a vertical cross section on the plane of the line 3 3 in Fig. 2.

In the accompanying drawings, in which similar numerals of reference indicate corresponding parts in the several views,'1 indicatesa lamp-body, which is shown provided with three main compartments 2 3 4. In the arrangement shown these compartments are formed by means of a horizontally-disposed partition 5, secured to the walls of the body, and a vertically-disposed partition 6, from which a top wall 7 extends'to and is connected with the walls of the body l, (see Figs. 1 and 2,) and thus the body and partitions 5 6 form the chamber 2, the body, with the pars. titions 5 6 andwall 7, form-the chamber 3, and the body and partition 5 form the chamber 4 beneath the chambers 2 and 3. The chamber 2 contains a burner 8, that communicates with chamber 4, and thus chamber 2 constitutes a fire-chamber. The chamber 3 constitutes a water-chamber and the chamber 4 a gas-generating chamber. The wall 7 is shown provided with a screw-cap 9 for the admission of water;

10 is a perforated cover or cap on body 1, that forms the cover of chamber 2.

The front wall of chamber 2 has an opening protected by a glass or other suitable protector 11, which in Fig. 1 is shown curved to correspond to the curve of body 1 and lies against the inner surface of the frontwall of chamber 2, and 12 is a reflector, which extends across chamber 2 at the back part of the same behind burner 8 and has its ends bent or curved forwardly, so as to engage the adjacent vertical edges of protector 11, and the reflector 12 preferably has a central de pression 12", which may be oval, that bears against the partition 6, and thus the parts 11 and 12 are braced against each other and held firmly within chamber 2. The parts 11 and 12 are inserted in chamber 2 by sliding them in through the top opening when the cover or cap 10 i'sremoved and they are held down by the cover or cap. V

13 is a conduit located within the waterchamber 3 and having one 'end leading through an opening in the bottom partition 5 thereof and its other end opening through the outer wall of said chamber. (See Fig. 3.) This conduit is provided with a valve '14, shown in the form of a screw or threaded stem meshing in threads in the conduit and having a tapering end 14 to'fit against a seat in conduit 13, an enlarged portion 13 of said conduit being in line with a rednced'portion' of the valve-stem, an aperture 13 in the'wall of the conduit permitting water to pass from chamber 3 into the conduit. The valve 14 is shown provided with a head 14 for operating it, and packing 15 serves to make a tight joint. The inner end of the conduit 13 leads to a hollow hanger or support 16, that is secured to the partition 5 and depends there- 0 from into chamber 4, said hanger being provided with internal screw-threads thatreceive corresponding threads on a depending tube 17. Said hanger is shown provided with a shoulder 16, against which a cup or the like 18 rests, the upper edges-of'said cup resting againstthe partition 5,and thus forming a chamber to contain a suitable gas-filter, one or more apertures 18 in the cup 18 permitting gas to enter the'same. The burner '100 8 leads to the chamber formed by the cup 18 and the partition 5. (See Fig. 2.) The hanger 16 also has external threads that mesh with internal threads at the upper end of a chamber 19, that has a closed lower end, the tube 17 projecting into said chamber to a point above the lower end of the latter, thereby forming a water-receptacle or well 20 between the lower ends of said parts. (See Fig. 3.) The chamber 19 is shown screwed against the bottom of cup 18, and thus, in con junction with the support 16, holds the latter pressed against the partition 5. 21 is an absorbent material, such as a fibrous wick, surrounding tube 17 and located within chamber 19, the lower end of the wicking leading to the water-receptacle or well 20 but not to the bottom of chamber 19. The chamber 19 near its upper end is provided with one or more ports 20 for the escape of water.

\Vhen the valve 14 is opened, water passes through conduit 15 and tube 17 into the receptacle or well 20 in chamber 19 and engages the wick 21, and is drawn up through the latter by capillary action, escapes through the port 20, and trickles down the exterior of chamber 19. The construction is such as to provide a uniform water feed, or one'that is not affected either by changing weight of water above the feed-tube or the pressure of gas at the outlet, and an alternating pressure between the gas and water is prevented. Thus the small well of water is at the lower part of the lamp,while the reservoir is above, and the feeding action of the water is by capillary attraction upwardly through the wick to the port 16, discharging above the carbid. Chamber 19 projects in calcic carbid to deliver water thereto. The chamber 19 is shown projecting through an aperture in the cover 22 of a carbid-receptacle 23, that is located within the lower end of chamber 4:, and held in place by a cap it, attached to body 1 by any suitable means, such as a pin and slot 25 26, whereby the cap can be removed. To make a gas-tight fit, the receptacle 23 is shown provided with a flange 23, that is alined with the end of body 1, between which a gasket 25 is located, and the end of body 1 is shown bent inwardly to form a somewhat broad seat for the gasket to rest against.

I do not limit my invention to the details of construction shown and described, as they may be varied without departing from the spirit thereof.
