PATENT OLIVER H. HAMPTON, OF WILLIAMSBURG, INDIANA.

ACETYLENE-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 674,698, dated May 21, 1901.

Application filed June 28, 1900. Serial No. 21,872. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER H. HAMPTON, a citizen of the United States, and a resident of Williamsburg, in the county of Wayne and State of Indiana, have invented a new and Improved Gas-Machine, of which the following is a full, clear, and exact description.

This invention relates to improvements in acetylene-gas machines; and the object is to provide a gas-machine of novel construction in which the gas will be automatically generated and in which there will be no danger of bursting by overpressure, and, further, to provide a means for automatically maintaining a uniform water-level in the generator.

I will describe a gas-machine embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of a gasmachine embodying my invention. Fig. 2 is a horizontal section of part of the same, and Fig. 3 is a section on the line 3 3 of Fig. l.

The generator comprises a cylinder 1, upon which is arranged a water-tank 2, the said water-tank having a depending flange 3, designed to engage closely in the upper portion of the cylinder 1 and extending below the water-line thereof, thus preventing any possible escape of gas except through an overflowpipe the upper end of which, outside of the cylinder 1, is extended out of doors. Extended upward from the bottom of the water-tank 2 and nearly to the top thereof is a pipe 4:, and a pipe 5, having a funnel-top 6, is extended through the top of the water-tank downward within thepipe 4 and nearly to the bottom thereof. Also extended through the top and bottom walls of the water-tank is a feed-pipe 7, having perforations 8 slightly above the bottom wall of the water-tank and adapted to be closed by a piston-valve 9, having a stem 10, extended upward through the pipe or tube 7. A valve-controlled vent-pipe 11 is arranged at the top of the water-tank.

Removably placed in the cylinder 1 is a tray-case 13, closed at the bottom and open at the top. Within the tray-case is arranged a series of carbid containers or trays l4=,formed into compartments, the said trays being arranged one above another, and each tray is provided with bails 15 for convenience in removing it from. the tray-case. Each tray is provided with a water-inlet 16 near its upper edge, and it will be noted that the traycase is provided with a water-opening 18 near the top. The upper open end of the traycase is closed by the top 21 of the water-seal jacket 12. At'the center of the top 21 is a dome 20, into which pipes 19 and 25 are carried above the water-level in the cylinder 1. Within the dome the top 21 is provided with apertures, as indicated by an arrow, through which gas may pass into the dome. The jacket is removably clamped over the tray-case by means of the jacket-pipe 19, the lower end of which is fastened to the bottom of the traycase, and the upper threaded end of said pipe 19 engages in a screw-threaded opening 26 in the top 21 within the dome, so that by rotating the jacket 12 it may be screwed down and held tightly in position.

The bottom of the carbid-holder is provided with angular legs 22, the horizontal portions of which are designed to engage underneath keepers 23, secured to the inner side of the cylinder 1, and these legs are also designed to rest upon brackets 2 1, arranged within the cylinder for a purpose to be hereinafter described.

The gas-pipe 25 passes upward through the jacket-pipe 19 and above the water-level, and an overflow-pipe 27 is arranged in the cylinder 1 to carry off water should the same rise above the required level. The gas-feed pipe 25 leads into a gasometer consisting of a fixed cylinder 28, in which is movable the bell 29. The pipe 25 connects with a pipe 30, extended vertically in the 'gasometer, and in the upper portion of this pipe 30 is a valve 31, to the stem of which a lever 32 is attached,

the said lever being extended into a longitu dinally-slotted rod 33, arranged in the gasometer. A by-pass or tube 34 communicates with the pipe 30 below the valve 31 and is then extended upward and then downward, its lower end terminating below the waterlevel in the gasometer. From the gasometer the gas passes through a pipe 35, which communicates with an outletpipe 36.

In operation the above-described carbidholder will be submerged in the water con tained in the cylinder and held in that position by the angular legs engaging underneath the keepers 23. It will be seen that the water will try to reach the same level both inside and outside of the carbid-holder and that it will rise between the walls of the tray-case 13 and the walls of the jacket 12 unless prevented by air or gas within the space between the walls of the tray-case and the jacket, and if the head of water in the cylinder 1 be high enough the water-pressure will drive the air or gas that is between the walls throughthe" opening 18 in the tray-case and be followed by the water, which will run down through a boxing X, attached to the inner side of the tray-case, and over the opening 18, passingthrough an opening 17 at the lower end of the boxing X, and will fi=ll beneath and around the lowest tray till it has risen to the Water-inlet 16 in the side of the tray, and thence into the first carbid-compartment of the tray-case, and the generated gas will pass out through the opening of the tray and into the gasometer through the pipes 25 and 30. The flow of Water and the production of gas will continue uninterruptedly so long as the relative conditions of water-head and gaspressure remain the same; but if the head of water be sufficiently decreased or the gaspressure sufficiently increased, so that the gas-pressure is the strongest, it will hold the water below the water-opening 18, and further gas generation must cease for lack of water.

In connection with this device there is shown in Fig. 1 an ordinary storage-gasometer, whose inlet-pipe 30 is fitted with a valve 31, operated by the lever 32, operated by the channel-bar 33, which rises and falls with the gasometerbell 29. When the valve 31 is open, as shown in the drawings, gas can pass freely into the gasometer, and a sufficient water-head being maintained from the reservoir 2 gas-making proceeds until the accumulation of gas under the gasometer-bell closes the valve 31, and any gas made after the valve is closed must go through the by-pass 34, which has its outlet end immersed in the water, and the resistance of the water raises the pressure in the carbid-holder sufliciently to hold the water that is between the walls of the tray-case and the jacket below the opening 18 in the wall of the tray-case, so that no more water can get to the carbiduntil the gas on hand is drawn oit for use. The automatic production of gas can also be eifected by establishing by ineansof the outlet-pipe 7 a waterlevel too low for the production of gas and using any suitable device for opening and closing the air-cock 11 as the gasometer-bell rises and falls or any other device which will pour a suitable quantity of water into the cylinder 1 as it is needed.

It is evident that a nearly-constant waterlevel must be maintained in the cylinder 1, and for this purpose I provide the reservoir 2. When the reservoir 2 is to be filled, the vent 11 must be opened and the valve 9 moved downward to close the openings 8. Then water poured into the pipe 5 will pass downward and then upward between said pipe 5 and the interior of the pipe 4 and over the upper end of said pipe 4. When the tank is filled, the water between the pipes 4 and 5 will form a seal to prevent the entrance of air. After filling the tank the vent 11 must be closed and the valve 9 is to be moved upward to open the perforations '8. If the water-level in the cylinder 1 is high enough to cover the lower end of the pipe '7, no water will flow through it; but whenever the end of said pipe is opened by the Water falling below it the water will flow from the tank 2 into the cylinder.

As before stated, if from any cause the water-level gets too high in the tank it is carried off through the pipe 27.

When the carbid charge is to be renewed in the several holders, the said holders, with the tray and tank, are to be rotated, releasing the legs 22 from the keepers 23, and then by lifting the said parts upward the'legs may be engaged on the brackets 24, which brings the top of the tray-case above the water-level, so it can be opened without water entering. Of course before this is done the water-tank 2 must be removed.

One advantage of the above-described apparatus is that the carbid-holder is entirely submerged in an ample quantity of water, and therefore the gas is kept cool. Another advantage is that the gas generation begins 1 claim as new and desire to secure by Letters Patent- 1.
