PECIFICATION forming part of Letters Patent No. 607,889, dated July 26, 1898. Application filed January 11, 1898. Serial No. 666,296. (No model.)

To all whom it may concern.-

Be it known that I, FRANK A. SMITH, of Oconto, in the county of Oconto and State of \Visconsin, have invented a new and useful Improvementin Apparatuses for Making Gas, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention has relation to improvements in apparatuses for making gas, pertaining more particularly to that class of apparatuses which are intended to be set up for use in dwellings, oftice-buildin gs, and the like in order that gas may be manufactured and supplied for particular premises.

The object had in view is to provide certain improvements upon the form of gas apparatus described and claimed in my pending application for patent for improvements for apparatuses for making gas, filed September 27, 1897, Serial No. 653,225, being intended to comprehend a more simple and compact form of construction than that covered in said pending application for patent.

With the above primary objects in view the invention consists of the devices and parts or their equivalents, as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a sectional view of the entire apparatus,showing a fragment of the gasolene-tank. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section through the carbureter. Fig. 4 is a section through the gasolene valve-casing and the valve mechanism thereof, and Fig. 5 is a section through the water-valve mechanism.

Referring to the drawings, the numeral 6 indicates a main storage-tank for containing gasolene or its equivalent.

The numeral 7 indicates a water-tank which is partially filled with water, and 8 the dis tributing gas-holder, consisting, as usual, of an open-bottom cylinder inverted into the tank. The holder is advisably provided at its top with projecting arms carrying rollers 9, which Work against guides 10 10 and serve to maintain the holder in true upright position and to also facilitate movement up and down of said holder. Extending through the lower portion of the tank 7 and up into the gas-holder for a desired distance is a gas-distributing pipe 11. This pipe after leaving the tank is extended upwardly, so as to conduct the gas to the different rooms or apartments to be lighted.

The numeral 12 indicates another watertank which is formed or provided with an inner wall 13, connected at its lowerend to the outer wall of the tank'and forming a space 14 'for the reception of oil or other suitable liquid 15 in order to provide a seal against the escape of gas. The upper endof the inner wall 13 is of a truncated conical form, and to the lower edge of this truncated cone is secured a packing 16 of leather or other desirable material. The edge of this packing projects for a desired distance beyond the conical surface.

The numeral 17 indicates an initial gasholder which is inverted into the tank 12 and is adapted to extend into the space 14 between the outer wall of the tank and the inner wall 13 thereof. It will be noticed that the outer edge of the packing contacts with the inner wall of the gas-holder 17, and consequently the upper end of the space 14: between the inner wall 13 and the inner side of the gasholder is thereby closed. The top of the gasholder 17 has also extending therefrom arms carrying at their outer ends rollers 18 18, which work against guides 19 19.

Extending upwardly from the bottom of the tank 12 into the chamber confined by the Wall 13 is a pump-cylinder 20. WVithin this cylinder is a piston 21, which has a stem 22 extending upwardly therefrom and through the top of the cylinder. The upper extremity of this stem is adjustably connected to the top of the gas-holder 17, as indicated at 23. Extending through the water-tank 12 and communicating with the lower portion of the pump-cylinderis a water-pipe 2 1. To the outer end of this pipe is connected a coupling, forming an interior valve-chamber 25. WVithin this chamber is a three-way valve 26, provided with two radiating fingers which contact with the inner circular wall of the valve-chamber. This valve is provided with a stem 27, which projects laterally through the valve-chamber, and to the endthereof is connected a crank 28. To this crank in turn is connected a vertical rod 29, which rod passes freely through an eye in an arm 30, projecting out from the top of the gas-holder 17. The rod carries thereon adjustable contactcollars 31 31, located, respectively, above and below the arm 30. The coupling forming the valve-chamber 25 has depending therefrom a water-outlet pipe 32, which is extended to any suitable point for discharge. The outer end of said coupling has connected thereto a nipple 33, which in turn connects with an elbow 34, said elbow having extending from its lower end an inlet-pipe 35.

The numeral 36 indicates a gas-generator or carbureter, consisting, preferably, of a cylindrical tank, which is partially filled with gasolene orother gas-producing medium. This tank is located within the chamber formed by the inner wall 13 of the water-tank 12 and rests on and is secured to the bottom of said water-tank 12. Extendingup from the bottom of the gas-generator is a cylinder 37. The cylinder is not in communication with the chamber of the gas-generator, so that an annular chamber is thereby formed in the lower portion of the gas-generator, which chamber is filled with the gasolene. Surrounding the cylinder 37 and located in the lower portion of the gas-generator is a perforated circular pipe or annulus 38, to which an air-pipe 39 connects, said pipe communicating with the external atmosphere. The cylinder therefore forms a small annular chamber in the gas-generator, and consequently but a small amount of gasolene is necessary to fill the chamber. WVithin a chamber at the outer end of the pipe 39 is a flap-valve 40. The air which enters the pipe 39 passes into the ring .or annulus 3S, and issuing out of the perforations thereof passes through the gasolene, being thereby impregnated with said gasolene and becoming a gaseous vapor, which enters the upper portion of the generator above the line of the gasolene, finally issuing out of a discharge-pipe 41 at the top of the generator and being discharged into the chamber formed by the inner wall 13 of the water-tank 12, from which chamber it is free to pass through the top opening thereof and fill the space below the top of the initial gas-holder 17.

From the gasolene storage-tank 6 extends pipe 41, which pipeleads to a gasolene valvecasing 42. The pipe 41 extends into this casing and connects with a coupling 43. One end of this coupling is extendedinto the pipe 41 for a short distance to form a valve-seat 44. Against this seat is adapted to work a valve 45, which is advisably pressed against by a spring 46 in order to assist in normally holding the valve against its seat. The valve is provided with an inwardly-extending valvestem 47, which extends through the inner end of the coupling and connects with the short arm of a bell-crank lever 48, said lever being pivoted at the point 49. The long arm of this lever carries a float-ball 50. Another pipe 51 leads from the gasolene valve-casing 42 and extends through the water-tank 12 and communicates with the gas-generator 36 near the lower end of said generator.

A pipe 52 extends from the top of the gasolene storage -tank, and is thence extended through the bottom of the Water-tank 12 and upwardly for a desired distance into the chamber confined by the inner wall 13. This pipe 52 is provided medially with a short branch pipe 53, which communicates with the gasolene valve-casing 42. The object of this pipe 52 and the branch pipe 53 is to secure at all times an equal pressure in the gasolene storage-tank in the gasolene valve-casing. It is obvious that the pressure of the gaseous vapor-beneath the top of the gas-holder17 will cause said gaseous vapor to pass through the pipe 52, thence through the branch pipe 53 into the gasolene valve-casing, and also flow through that portion of the pipe 52 leading to the gasolene storage-tank, thereby producing equal pressures in said tank, and into the gasolene valve-casing.

Within the bottom of the chamber formed by the inner wall 13 and below the Water-line is arranged a circular steam-pipe 54. This pipe has an inlet-pipe 55, communicating therewith and leading from any suitable source of steam-supply,and a discharge-pipe 56,1eadin g therefrom. The object of the circular steampipe is to provide as near as possible an equal temperature to the Water in order to prevent said Water from freezing. If desired, the steam-pipe 54 may be entirely omitted and the temperature of the water in the tank regulated solely by the temperature of the in-.

flowing water to the pump.

The circular chamber confined by the wall 13 is connected with the terminal gas-holder 8 by means of a pipe 57. The end of this pipe within the chamber formed by the inner wall 13 is located therein above the waterline and is then extended downwardly and outwardly through the tank 12, thence to and through the water-tank 7, and its discharging end is formed or provided with an elongated conical portion 58, the upper extremity of said discharging portion extending a distance into the gas-holder 8 at a point just above the upper edge of the water-tank 7 To the end of the pipe 57 which is located within the chamber formed by the inner Wall 13 is connected a coupling 59, which forms a valvechamber for a flap valve 60. Extending through the upper end of the conical portion of the pipe 57 and into said conical portion for a desired distance is a rod 61. The lower end of this rod, within the conical portion, is formed with a ball-valve or enlargement 62. At the top of the gas-holder Sis formed an upwardly-extending tubular boss 63,to which is adjusted a screw-cap 64. The upper end of the rod 61 is threaded and passes through a plain opening in the screw-cap. Nuts 65 65 are turned on the threads of the rod and are located above and below the top of the screwcap, as clearly shown. rod, itis obvious that all that is necessary is to turn the screw-cap in the proper direction to either raise or lower the rod, as desired.

The operation of my improved apparatus is as follows: The liquid gasolene is free to enter the gas'generator 36 whenever the valve 45 is away from its seat. The valve is moved away from its seat whenever the float 5O falls to such an extent by the lowering of the level of the gasolene in the generator and in the gasolene valve-casing as to act on the stem of the valve and force said valve away from its seat against the pressure of the coiled spring. As soon as the generator fills to a certain height the float is again raised to such an eX- tent as to force the valve against its seat and stop further inflow of the gasolene.

In this position of the three-way valve 26 water from the source of supply is free to flow through the inlet-pipe 35, thence through the passage of the valve-chamber 25 formed between the radial arms of the valve, thence into the pipe 24, through which pipe it is conducted into the lower end of the pump-cylinder in the space beneath the piston 21. The pressure of the water against said piston will cause the piston to rise, and with this upward movement the piston-stem 22, by its direct connection with the gas-holder 17, will cause an up movement of said gas-holder. With the raising of the gas-holder a vacuum is formed therein and a suction is created through the pipe 39, which opens the flapvalve 40 and draws the external air through said pipe into the annulus or ring 38, and thence out through the perforations of said .ring, and, becoming thoroughly impregnated with the gasolene, issues into the space confined by the inner wall 13 in the form of a gaseous vapor, which fills up the space above the water-line, the oil forming a seal against the escape of the gas. After the gas-holder 17 has moved a certain distance upwardly the arm 30 will contact with the collar 31 and cause an up movement of the rod 29. This arm will therefore turn the crank 28, so as to shift the three-way valve 26 and put the pipe 2a into register with the discharge-pipe 32 and at the same time to close the inlet. The water is now free to pass out of the pump-cylinder.

In further explanation it will be understood that if gas is permitted to pass out of the pipe 11 the gas-holder will necessarily descend, so as to move the ball-valve 62 away from the contracted portion of the conical discharge 58. This will at once permit gas in the holder 17 to flow through the pipe 57 into the gasholder 8, so as to fill said gas-holder with a quantity of gas equal to that withdrawn therefrom, and this operation takes place before any operation whatever of the pump mechanism occursthat is to say, the gas: holder 17 descends a certain distance in order to force gas into the holder 8, and after said holder 17 has descended a sufficient distance to cause the arm 30 to contact with the In order to adjust the collar 31 the valve 26 is turned back to the position shown in Fig. 5, when of course the operation first explained again takes place.

It will be understood that if after the outlet-pipe is opened and the water beneath the piston flows out through this pipe and the gas is turned off or is not being used then the piston will remain at its adjusted position. It will be understood that on the lowering of the gas-holder 17 the flap-valve 6O is'opened and thegas is forced into the pipe 57 and discharged through the conical portion 58 of said .pipe.

The rod 61 and the ball-valve 62 at the lower end thereof are not only for the purpose of governing the amount of gas entering the holder 8, but are also for the purpose of controlling the distance the gas-holder S can be raised vertically-that is to say, they prevent said gas-holder from being raised to such a vertical height as to bring its lower edge above the water-line, and thereby allow the escape of gas. The rod is so adjusted that after the gas-holder has been raised to such a height as to bring its lower edge nearly to the surface of the water the valve 62 will have been raised sufficiently high to bring it into the contracted portion of the conical discharge, and thereby close the piston against further flow of the gas into the gas-holder.

From the above description it will be seen that in my improved apparatus the gasis forced from the initial gas-holder 17 into the distributing gasholder 8 by means of the descent by gravity of the gas-holder 17, while said gas-holder 17 is raised by means of a pump having its piston-stem in direct connection with the gas-holder. The ball-valve 62 necessarily produces an even feed of the gas into the holder 8, and consequently an even pressure of the gas in said holder.

It will be seen that my invention differs from that described in my pending application for patent, filed September 27,1897, Serial No. 653,225, hereinbefere referred to, more particularly in the compact arrangement of the parts. In said pending application the gas-generator and the pump mechanism are not arranged within the initial water-tank, as is the case with my present improvements. In the present improvements the pump mechanism and gas-generator are located within the initial Water-tank, and I also provide Within said tank a suitable means for securing an even temperature of the Water. Furthermore, an improved construction of gas-generator is also provided, and, still further, the piston-rod of the pump is connected directly to the top of the initial gas-holder instead of being connected through the intermediary of a rocking lever, as in my pending application. I have also improved the form of construction of the initial water-tank in the provision of an interior wall forming an annular chamber for the reception of oil, as hereinbefore described.

It will be obvious that in the present ara distance from the other parts of the apparatus, so that danger from explosion is reduced to the minimum.
