SPECIFICATION forming part of Letters Patent No. 581,020, dated April 20, 1897.

Application tiled December 15,1896. Serial Nol 615,830. (No model.)

To aZZ whom it may concern.-

Beit known that I, WILLIAM II. DENNIS, of the city of Minneapolis, county of Henne pin, State of Minnesota, have invented certain new and useful Improvements in Acetylene-Gas Lamps, of which the following` is a specification. A

My invention relates to acetylene-gas lam ps; and the object of this invention is to modify and improve the acetylene-gas lamp or generator shown and described in my application, Serial No. 610,280, iiled October 2S, 1896.

A further and particular object of the invention is to provide a neat and symmetrical lamp which will be capable of holding a large body of gas and wherein the pressure is at all times equalized; and, further, a lamp wherein a larger supply or head of water may be maintained; and, further, to .render the two parts or cylinders of the lamp or generator practically the same in appearance; and, further, a detail object is to construct the lamp in a cheaper and more durable manner.

With these ends in view my invention consists generally in the combination of a suitable support with two cylinders or chambers, one devoted to the gas-generator and the other to the watersupply and gas-purifier, though the latter may, if desired, be omitted.

The invention consists, further, in particular means of joining the two cylinders and forming the ducts connecting the same; and, further, in a movable gas-holder used in conneotion with the generator.

The invention consists, further, in regulat- .ing means arranged in connection with the movable gas-holder; and, further, in particular constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming part of this specification, in which Figure 1 is a verticalsection of an acetylene-gas lamp or generator embodying my invention. Fig. 2 isa sectional view thereof on the line .fr 0o of Fig. 1 and showing particularly the means for regulating the ow of water to the generator.

As shown in the accompanying drawings, the lamp is in gen eral appearance practically the same as that described in my above-mentioned application and may, like that, be supported upon a standard. I have here shown the lamp provided with a bracket by which it may be fixed upon a side wall.

2 and 3 are the main cylinders or chambers of the lamp. The former is provided with an interior wall or chamber Ll, the two being connected by the annular bottom 5. The edge of the cylinder 2 projects below this bottom 5 to provide space for the packing-ring 6 upon the cartridge 7. This cartridge is of a size to iit into the cylinder and is held therein by friction.. The bottom 8 of the cartridge is preferably formed with the hopper or cavity 9 to receive the refuse. IO indicates a screen bottom in the cartridge. The cartridge may at any time be drained through the valve 1I.

In the upper part of the cylinder 4 is a perforated diaphragm or cone I2. As indicated, the water rises nearly to the top of the opentopped cylinder 4E and enters the cylinder and the cartridge through the small holes or perforations 13 provided in the upper part of said cylinder t. From thence it flows downward and distributes itself over and through the diaphragm or cone 12, so that it is quite evenly distributed over the mass of calcium carbid in the cartridge '7. `The top of the cylinder 2 is open to receive the movable gasholder I5, which is itself open at the bottom and adapted to sink into the annular waterleg formed between the cylinders 2 and 4. The gas-holder has a solid heavy top 1G,which has a weight to counterbalance the pressure of the gas in the upper part of the same and by which pressure of the gas is equalized regardless of its volume. The other cylinder 3 is divided into two parts by apartition I7, and about two-thirds of said cylinder is employed as a water-chamber, which may be filled through the opening I8 in the top. The lower part of the cylinder is employed as a gas-chamber, and in this the gas-purifying agent is placed, if used. In the upper part or watertank portion of the cylinder 3 is a gascoil I9, the gas in which is cooled by the surrounding water.

The upper end of the gas-coil I9 is connected with the gas-outlet pipe 20 in the gas-chamber of the generator; The lower end of the coil is fastened in the sleeve or collar 2l in IOO the partition 17. A pipe conducts the gas from the chamber 2S beneath the partition I7 to the gaspipe 24, with which the burners are connected. The lower end of the cylinder is closed by the bottom 25, provided with the dripeock 2G, and which carries the cylinder or basket 27 to contain the purifying substance or agent.

2S is a screen or perforated bottom for the basket 27, and 2t) is a central tube preferably fastened and supported by the spider-arms 30. rlhe upper end of this tube 29 is threaded to enter the threaded lower end of the sleeve or coupling l in the partition I7, and when the bottom is turned itwill be drawn up thereby. so that the packing-ring 3l will be compressed to make a gas-tight joint between the lower edge of the cylinder and the bottom 25. The bottom 25 is preferably formed with a residue-pocket 32 similar to that in the bottom of the other cylinder. The gas-pipe 2O leads from the space above the water-distributing cone or diaphragm and downwardly between the cylinder i and the gas-holder.

Si represents a casting upon which the two cylinders are secured,and this casting is cored to form the duet 35, the duct 3G, and the duct 37. The duct connects the lower part of the water tank or chamber in the cylinder 3 with the water-leg around the cartridge in the generator.

In the water-duct 35 I provide a small valve 3S of any suitable form and here considerably exaggerated in size. rlhe water maybe shutoft' or regulated by means of this valve, and to automatically control the ilow of water I provide a lever 3) on the valve and connect the same with the movable gas-holder which forms the top of the generator. In order to permit a considerable latitude of movement, I prefer to connect the lever and the gas-holder by a light spring it), counterbalanced on the opposite side by another spring il. These springs are preferably inelosed in telescoping tubes, whereby the springs are concealed, and the upper ends of the springs are connected with the gas-holder by loose links or rings yl-Bgvhich may be easily detached from the lugs ttt on the holder. The lower end of the spring` t0 is preferably connected to the lever 39 by a hook Al5 or other means, whereby the lever may be released to permit the closing of the valve byhand. The lever 3f) is preferably provided with weights 4G to render its return movement automatic. The duct 3G serves to connect the lower end of the pipe 20 with the gas-coil, a part t7 of which extends upwardly to the top of the coil, from whence the gas flows downwardly and iinally delivers into the tube 29 and the space beneath the purifier-basket. From thence the gas rises through the purifying substance and passes off tothe burners through the pipe 29, duct 37, and gas-pipe 2t.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. In an acetylene-gas lamp, the combination, with a suitable cylinder provided with an annular water-leg, of a movable gas-holder forming the top of said cylinder and adapted to sink into said water-leg, a removable bottom for said cylinder, a cylinder or cartridge carried thereby and adapted to be inserted into the bottom of said cylinder, suitable means forpacking the joint between the same, means for distributing water over the material in said cartridge, and a gas-outlet pipe leading from the top of said cylinder downward to a point beneath the lower end of said gas-holder, substantially as described.
