ACETYLENE-GAS GENERATOR SPECIFICATION forming part of Letters Patent No. 589,799, dated September 7', 1897. Application filed April 5, l897. Serial No. 630,671. (No model.)

To rt/Z whom, it irtag concern..-

Be it known that I, GEORGE TAYLOR, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented a new and Improved Gas-Generator, of which the following is a specification.

Thi s invention relates to apparatus for generating acetylene gas, means for regulating and purifying the gas, and means for removing sediment of carbid from which the gas is generated. I accomplish these obj eois by the hereinaftendescribed apparatus.

Other objects and advantages will be fully understood from the following description and claims when read in connection with the is accompanying drawings, forming a part of tom 2 is fastened securely to the wall of case 1, forming a space or chamber 2. The case 1 is divided. into apartments 19 and 19 by a wall 16, which is fastened securely to false bottom 2' and to the sides of easing 1, so that the apartments are water-tight. On top of bottom 2 is fastened an inverted cylinder 12 in the apartment 19, and in apartment 19 an inverted cylinder 12 is fastened to bottom 2'. \Vithin apartment 19 is mounted an inverted cylinder 4;,that fits loosely around cylinder 12, and within apartment 19 is mounted another inverted cylinder et', which fits loosely around cylinder 12. Cylinder a is provided with a screw-cap 4." or any other suitable device to close the cylinder air-tight after carbid has been put in the cylinder 4. At a suitable place within cylinder 4: is mounted an arrangement for holding carbid, using the partly-spent carbid or residuum and disposing of the sediment after all the gas has been generated from it.

A holder constructed in two sections, a band or upper section 18, having perforations 1S,

and a funnel-shaped basket 11 securely fastened to band 18. This basket has a solid bottom with an opening for pipe 11. Band 18 has an offset by which the band is attached to the wall of cylinder 4. By means of this offset band 18 is far enough away from the Wall to permit water to run in the perforations 1S. Awire screen 10 of any convenient mesh is fastened at or near the middle part of band 18 for holding carbid. Below screen 10, about at the bottom of band 18, is mounted a perforated disklO. Inside of cylinders is a pipe 6, having a funnel or gas-collector 6, which passes through false bottom 2 and projects into the inverted cylinder or purifier 4: to any convenient location. Pipe 6 passes through screen 10 disk 10, and through basket 11. In the head of cylinder 4" is mounted a'p'itman 7, having a movable joint 7 and fastened to another movable joint 7", which is part of valve 7 which has a hinged support 7'. A pipe 13, connected to pipe 11, passes downward and through false bottom 2, then out of case 1, and is provided with a valve 13". On the outside of easing 1, extending all the way around -or only partly around, as may be convenient, as shown in Fig. 3,'is a reserve tank A pipe 15 is inserted in tank 3 and is provided with a shut-off valve 15'. This pipe 15 passes into casing 1, then up through pipe 13 and the carbid-holder and perforated disk 10, and then, by means of elbows, has a short return-bend. In the purifier a is located a pipe 8, provided with a funnel-shaped top or gas-collector 8. This passes downward and through false bottom 2, then up by the side of easing 1 to the top, and then turns at a right angle to any desirable point. This pipe is provided with a shut-01f valve 9. The cylinders 12 and 12 act as guides for cylinders 4 and 4t.

The mode of operation maybe described as follows: Cap l is removed and carbid is inserted and placed on screen 10. then screwed on air and gas tight. ater is put in space 19 for the double purpose of generating gas and to prevent the escape of same. YVater is put in space 19" also to prevent escape of the gas. When water rises high enough in cylinder 4 to flow through perforations 18, it will come in contact with the carbid and gas will be generated. As the gas The cap is ing the sediment.

is generated the funnel G will collect it. The gas will go down pipe (5, as indicated by arrows, into the receiver or purifier at. As this tank is surrounded by cold water, it acts as a condenser and purifier of the gas. lVhen the gas is received into tank or cylinder 4, it is collected by the funnel 8 and conducted through the pipe 8, as shown by arrows, to any desirable place or mains. If the gas is generated more rapidly in cylinder 4 than is being consumed, the pressure of the gas through pipe 6 into cylinder 4: raises this cylinder and consequently pitman 7, which,

presses valve '7 against the discharge end of pipe 6 and therefore cuts off the supply from cylinder 4. No more gas can enter cylinder 4 until the pressure is reduced. hen this is done, cylinder 4 will fall by gravity and consequently open valve '7 and thus get a fresh supply of gas from cylinder 4. lVhen more gas is generated in cylinder 4 from any cause than can escape through pipe 6 into cylinder 4, pressure of gas on head of cylinder at will increase till it raises cylinder & to position indicated by dotted lines, and is prevented from rising still higher and out of apartment 19' by chains 14, which are attached to the top part of cylinder 4 and to casing 1 and to division-wall 16 in any suitable way, as by rings 20. A similar arrangem ent is provided for holding cylinder at down.

As the holder containing screen 10 and disk 10 is fastened to cylinder 4 and the carbid is resting 011 screen 10, it follows that the carbid will be automatically raised out of the water, which comes about up to line 17. henever this is done, the generating of gas will cease, as gas is generated from carbid only when the carbid is in contact with water. When the gas has been consumed enough to relieve the pressure from the head of cylinder 4, this cylinder will fall by gravity and again bring the carbid into the water, and consequently the generation of gas commences again.

One great difficulty experienced in making acetylene gas has been that it is not possible to get all of the gas out of the calcium carbid. The reason of this is that when water comes in contact with the calcium carbid a portion of the carbid is immediately dissolved. In the process of disintegration a large amount of sediment is produced. The sediment surrounding the carbid disintegrates the carbid before all the gas has escaped from the carbid. The sediment absorbs the gas from the carbid, carrying it down the pipe for discharg- This causes the loss of a The holder above described is devised to prevent this loss. Oar-bid is placed on the wire screen 10. As soon as water comes in contact with the carbid through perforations 18 a portion of the carbid is disintegrated and the residuum immediately falls through the meshes of the screen 10 onto the disk 10, leaving the calcium carbid clear from any sediment. Consequently there is nothing to prevent the generation of gas from the carbid. Another advantage of this plan is that when the sediment is immediately separated from the car- 'bid there is a little free gas in it, which may be utilized by catching the sediment on the perforated disk 10. The remaining gas being extracted from the sediment, the water carries the sediment to the inclined plane of basket 11, whence it passes out pipes 11 and 13. The tank 3 is filled with water, and by opening valve 15 water flows through pipe 15 and through pipe 11.

It will be seen that the apparatus can be easily cleaned of all sediment.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
