To aZZ whom, it may concern;

Be it known that I, FRANK A. SMITH, of Oconto, in the county of Oconto and State of Wisconsin, have invented a new and useful Improvement in Apparatus 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 apparatus for making gas; and it pertains more especially to that class of gas apparatus which is intended to be set up for use in dwellings, hotels, office-buildings, and the like in order that gas may be manufactured andsupplied for a'particular premises.

The primary object had in view is to secure a uniform pressureof the gas in the distributing gas-holder, this being accomplished by forcing liquid gas from the storage-tank to the generator and providing means for raising the initial gas-holder, so that a vacuum is formed in said holder and the vapor gas thereby admitted therein from the generator, and also providing means for causing a subsequent descent of the initial gas-holder by gravity, so as to force the vapor gas into the distributing gas-holder, ball-valve mechanism in the distributing gas-holder compelling uniform pressure of the gas.

An incidental object contemplated is the automatic regulation of the quantity of gas admitted to the distributing gas-holder.

A still further object resides in a novel and improved form of valve mechanism for the forcing-pump.

With the above and other incidental objects in View the invention consists of the devices and parts or their equivalents, as here- 'gasolene or its equivalent.

The numeral 8 in dicates a water tank, which is partially filled with water, and9 the distributing gas-holder, consisting, as usual, of an open-bottom cylinder inverted into the tank. The gas-holder is advisably provided at its lower end, upon its outer side, with rollers 10 10, which are adapted to bear against the inner side of the tank 8, and the tank 8 may also be provided at its upper end with similar rollers 11, which bear against the holder. These rollers serve to maintain the holder in true upright position and also facilitate the movement up and down of said holder. EX- tending through the lower end of the tank 8 and up into the gas-holder 9 is a gas-distributing pipe 12. This pipe after leaving the tank is extended so as to conduct the gas to the different rooms or apartments to be lighted.

The numeral 13 indicates an initial gasholder which fits and is adapted to reciprocate in a water-tank 14, partially filled with Water. The lower end of this gas-holder has projecting outwardly and upwardly therefrom an annular flange 15, which bears at its outer upper edge against the inner side of the tank 14 and serves to maintain the gasholder in true position within the tank.

The cylinder of the pump mechanism is indicated by the numeral 16. Within this cylinder is a piston 17, which is provided with an upwardly-extending piston-rod 18, which rod extends through the top of the pump.

Projecting upwardly from the top of the gasholder 13 is an arm 19,,which forms a fulcrum for a rocking lever 20, one end of said rocking lever being pivotally connected to the upper end of the piston-rod and the opposite end of said lever being pivotally connected to an arm 21. The lower end of this arm 21 is pivotally connected to an upright 22.

An air-pipe 23 extends from the upper end of the pump-cylinder to the upper end of the gasolene-storage pipe 7. The passage of the air through this pipe is controlled by means of a flap-valve 24. Extending into the upper end of the pump-cylinder also is a short airintake pipe 25, which has connected to its outer end a coupling 26, forming a valve- Y chamber for a flap-valve 2'7. Entering the lower end of the pump-cylinder is a waterinlet pipe 28, which leads from the city waterworks or from any suitable source of watersupply, so as to conduct water under pressure to the lower end of the pump-cylinder in the space beneath the piston thereof. A water outlet or discharge pipe 29 leads from the lower end of the pump-cylinder. In each of these pipes is mounted a crank-shaft. The crankshaft of the inlet-pipe is designated by the numeral 30 and that of the outlet-pipe by the numeral 31. The cranks of these respective shafts extend in opposite directions. Within the inlet-pipe is formed a valve-seat 32 and within the outlet-pipe a similar seat 33. Against these seats are adapted to work, respectively, inlet and outlet valves 34 and 35. These valves are provided, respectively, with projecting stems 36 and 37, said stems being connected to the respective cranks of the shafts 30 and 31. To the outer exterior ends of the shafts 30 and 31 are connected, respectively, crank- arms 38 and 39.

' Connected to and extending from the pumpcylinder, near the lower end thereof, is a bracket or arm 40. Pivoted on this bracket at the point 41 is a tumbling-bob consisting of an upright arm 42, provided at its upper end with a weight 43 and an intersecting cross-arm 44. To one end of the intersecting arm is connected a rod 45. This rod extends upwardlya desired distance above the top of the pump-cylinder and has mounted thereon, at desired distances apart,ad j ustable contactcollars 46 46'. Connected to the crank- arms 38 and 39, which are connected, respectively, to the outer ends of the shafts 30 and 31, are other rods 47 47, said rods passing through opposite ends of the intersecting arm 44. Rod 47 has mounted thereon above and below the end of the intersecting arm through which it passes adjustable contact-collars 48 48, and

rod 47 has mounted thereon at correspond- 4psoints similar adjustable contact-collars On the upper end of the piston-rod 18 is adjustably mounted an arm 49. The rod 45 passes freely through an opening in the end of this arm, said end through which the rod passes being located between the adjustable collars 46 and 46.

The numeral 50 indicates the gas-generator, consisting of a cylindrical tank, which is partially filled with gasolene. A pipe 51 extends from the lower end of the gasolene-storage tank 7 and connects with a supplemental chamber 52, projecting laterally from the gasgenerator. This pipe extends into said supplemental chamber and connects with an L-coupling 53. One end of the L-coupling is extended into the pipe 51 for a short distance to form a valve-seat 54. Against this seat is adapted to work a valve 55, said valve provided with an inwardly-projecting spring-actuated valve-stem 55, which extends through the inner end of the L-coupling and connects with a short arm 56, extending from a lever 57. Said lever is pivoted to a projecting lug 58, and at the extremity of said lever is connected a float 59.

The numeral indicates an air-intake pipe which at its outer end communicates with the external atmosphere, and its lower end extends into the generator-tank and connects with a perforated ring or annulus 61, which is located in the lower part of the tank and is adapted to be submerged by the gasolene contained therein. To the outer upper end of the pipe 60 is connected a coupling 52, forming a valve-chamber for a flap-valve 63. From the top of the gas-generator projects a pipe 64, which pipe is extended to and into the water-tank 14 and thence upwardly into the gas-holder 13 for discharging into the space of the gas-holder above the water-line.

The numeral indicates a pipe which connects the gas-holders 9 and 13. this pipe is located in the space of the gasholder 13 above the water-line, and is then extended downwardly and outwardly through the water-tank 14, thence to and through the water-tank 8,andits discharging endis formed or provided with an elongated conical portion 66, the upper extremity of said conical discharging portion extending a distance into the gas-holder 9 at a point just above the upper edge of the water-tank 8. To the end of the pipe 65 which is located in the gas-holder 13 is connected a coupling 67, which forms a valve-chamber for a flap-valve 68. Extending through the upper end of this conical portion and into said conical portion for a desired distance is a rod 69. The lower end of this rod, within the conical portion, is formed with a ball-valve or enlargement 70. The rod is made adjustable by threading its upper end and passing said threaded end through an opening 71 in the top of the gas-holder 9. Nuts 72 72 engage the threads of the rod and are adapted to be turned up against opposite sides of the top of the gas-holder, as clearly shown in Fig. 1, in order to adjust and hold the rod to adjusted position. An opening 73 is provided in the top of the gas-holder 9, which opening is covered by means of a screwcap 74. By removing this screw-cap access can be readily obtained to the interior for the purpose of adjusting the inner nut 72.

The operation of my improved apparatus is as follows: The liquid gasolene is free to enter the gas-generator 5O whenever the valve 55 is away from its seat and there is a pressure on the surface of the gasolene within the gasolene-tank. The valve is moved away from its seat whenever the float falls to such an extent by the lowering of the level of the gasolene in the generator as to act on the rod of said valve and force the 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 extent as to force the valve against its seat and stop further inflow of the gasolene. It will be understood that the coiled spring is not absolutely necessary, as the float itself would be sufficient to force the valve to its seat.

In the open position of the water-inlet valve One end of IIO piston will cause the piston to rise, and withthis upward movement the lever will be acted upon. This lever through the connecting-arm 19 will raise the gas-holder 13. With the raising of said gas-holder a vacuum is formed therein and a suction is created through the pipe 60, which opens the flapvalve 63 and draws the external air through said pipe into the annulus or ring 61 and thence out through the perforations of said ring. The air thus issuing through the perforations passes into and through the gasolene and is thoroughly impregnated therewith, becoming agaseous vapor,which enters and fills the space of the gas-holder 13 above the waterline, the water forming a seal against the escape of the gas. ton-rod 18 has moved a certain distance upwardly the contact-arm 49 thereof will contact with the contact-collar 46 and cause an up movement of the rod 45.

Figs. 1 and 3 show the arm'in contact with the collar 46. This rod will act on the end of the crossarm 44 and cause a tilting of the tumblingbob mechanism in a direction to the right of Fig. 3. Fig. 3 shows the arm 42 moved as far as a vertical position. The moment the upright arm 42 is tilted past this vertical position the weight 43 completes the movement of the tumbling-bob. There is a slight lost motion in the cross-arm 44 until the ends thereof contact with the contactcollars 48 and 48. Contact with the collar 48 will cause a turning of the crank-shaft 30, so as to close the inlet-valve 34, and contact with the collar 48 will cause a turning of the crank-shaft 31, so as to cause an opening of the outlet-valve. The wateris 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 12 the gasholder 9 will necessarily descend so as to move the ball-valve 70 away from the contracted portion of the conical discharge 66. This will at once permit gas in the holder 13 to flow through the pipe into the gas-holder 9, so as to fill said gas-holderwith a quantity of gas equal to that withdrawn therefrom, and

this operation takes place before any operation whatever of thepump-valve mechanism occurs-that is to say, the gasholder 13 descends a certain distance in order to force the gas into the holder 9, and after said holder 13 has descended this certain distance the arm 49 will contact with collar 46 and throw,

the tumbling-bob mechanism in a direction to open the inlet and close the outlet valve,

let-valve is open and. the water beneath the piston flows out through the outlet-valve, the gas is turned off or is not being used, then the After the pispiston will remain at its adjusted position. It will also be understood that on the lowering of the gas-holder 13 the pressure through the pipe 64 causes a closing of the flap-valve 63, so that no escape can occur through the pipe 60, while at the same time the flap-valve 67 is opened and the gas forced into the pipe 65 and discharged through the conical portion 66 of said pipe. It will be evident that whenever the piston 17 ascends the air in the cylinder above said piston is forced through the pipe 23 into the tank '7, so as to act on the up per surface of the gasolene contained in said tank and force saidgasolene through the pipe The rod 69 and the ball-valve 70 on the lower end thereof are not only for the purpose of governing the amount of gas entering the holder 9, but are also for the purpose of controlling the distance the gas-holder 9 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 the 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 70 will have been raised sufliciently 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 gasholder.

From the above description it will be seen that in my improved apparatus the gas is forced from the initial gas-holder 13 into the distributing gas-holder9 by means of the de scent by gravity of the gas-holder 13, While said gas-holder 13 is raised by means of a pump. The ball-valve 70 necessarily produces an even feed of the gas into the holder 9, and consequently an even pressure of the" In other forms of appagas in said holder. ratuses the gas is forced from the'initial gasholder into theterminal or distributing gas holder by means of pump mechanism, which is found objectionable in that an uneven pressureis produced. Attention isalso called to the fact that all of the parts of my apparatus need not necessarily be located in one building, but that the gasolenestoragetank 7 may be located at one place, the water-tank 8 and the gas'holder 9 fitting therein at another place, while the water-tank 14 and gasholder 13, together with the generator 15, may be located at still another point. In many forms of apparatuses all of the different portions thereof are required to be located at one point. i
