SPECIFICATION forming part of Letters Patent N 0. 663,293, dated December 4, 1900.

Application filed March 12, 1900. Serial No. 8.351. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM HAMILTON MOGOLDRIOK, a citizen of the United States, and a resident of San Antonio, in the county of Bexar and State of Texas, 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 machines for generating acetylene-gas; and the object is to provide a gas-machine ot' simple and comparatively inexpensive construction, in which the gas is thoroughly washed before entering the servicepipe and in which the water-su pplyto the generator is controlled by the gas-pressure and the carbid kept at all times cooled by surrounding water,

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 perspective view of a gasmachine embodying my invention. Fig. 2 is a plan view and partial section on the line 2 2 of Fig. 3, and Fig. 3 is a section on the line 3 3 of Fig. 2.

The gasometer comprises a fixed tank 4, in which a hell 5 is movable, and the bell is guided in its upward and downward movements by rods 6, extended upward from the tank 4, and with which grooved rollers 7 on the top of the bell engage. Arranged on the top of the bell is a generator-dome consisting of an outer wall 8 and an inner wall 9, the space between these walls being designed to receive water to serve as a seal for a cover 10, having a wall 11 extended down into the water, as plainly indicated in Fig. 3. As a further means for providing a gas'tight con nection between the cover and the gen eratordome I may employa gasket 12, of rubber or the like, arranged between the cover and the inner wall of the generator-dome.

The generator consists of a cylinder 13 extended upward from the bottom of the tank 4and arranged within a jacket 14, which depends froin the top of the bell 5 and has its open upper end extended upward slightly above the bottom portion of the generatordome wall 9, thus forming a water-space between said jacket and the wall 9, and through this water the generated gas is designed to pass, so as to be thoroughly washed.

An open work carbid -basket 15 is supported in the cylinder 18. As here shown, the basket has arms 16, designed to engage over the upper end of the jacket 14, and to these arms 16 a suitable handle 17 is attached, so that the basket may be readily removed or inserted after removing the cover 10.

A pipe 18 provides communication between the interior ofthe wall 9 of the generator-dome and the space in the bell 5 above the water contained therein. From this space in the bell the gas passes through the service -pipe 19, which has its upper end within the bell extended above the water-level. A drip-pipe 20 leads from the lower portion of the service-pipe 19 into the water contained in a bucket or tank 21. This pipe is designed to carry off the moisture escaping from the gas passing through the service-pipe. A safety or blow-off pipe 22 extends upward into the bell and into a jacket 23, carried by said bell.

Arranged in the service-pipe is a shell 19, design ed to receive cotton or similar material for cleaning the gas passing therethrough. The cotton may be replaced with new cotton, as required, upon removing the screw-plug at the end of the shell and after closing the valves at the ends.

Under excessive pressure or excessive amount of gas in the bell it will be raised until an opening 24 reaches a point above the level of the water in the bell. Then the surplus gas may escape through said opening 24 and pass out through the pipe 22 and through a communicating pipe 25, leading therefrom to the outer atmosphere. This pipe 25 also has a drain-pipe 26 extended into the water in the tub 21. The pipe 18 is provided with a valve 27 and also with a vent 28, so that when the valve is closed to cut off the passage of gas from the generator to the bell the said vent will be opened to allow waste gas to blow off. If desired, the vent may be connected to the top of the jacket 23.

Attached to one side of the tank 4, near its top, is a trough 29, which communicates through an opening 30 with the interior of the tank 4. From the trough 29 a pipe 31, having a valve 31, leads to a pipe 32, vhich communicates with the interior of the generatorcylinder 13. The bottom of the cylinder is made funnel-shaped, as plainly indicated in Fig, 3, so that Waste products falling from claim as new and desire to secure by Letters the basket 15 will readily pass into the pipe 32, from which they may be Withdrawn with the water after opening a valve 33 in the pipe 32. By this means the generator may be thoroughly and quickly cleaned.

In operation, after placing water in the space between the walls 8 and 9 of the generator-dome, and also placing water in the tank 4, the said water extending upward into the bell and into the space between the cylinder 13 and the jacket 14:, the basket containing the carbid is to be placed in the generator, after which the cover 10 is to be placed in position and securely locked. As a locking means I have here indicated pins extended inward and downward from the top of the wall 8 and adapted to engage in bayonet slots or notches formed in the top wall of the generator-dome. Water poured into the trough 29 will pass through the pipe 31 into the generator-cylinder 13 to a level slightly above the bottom of the basket suspended in the cylinder. After thus placing the parts in operative position the subsequent action is practically automaticthat is, in its supply of water to the generator-because the pressure of gas in the bell will force the water downward in the bell, causing it to rise at the outer surface of the bell and pass through the opening 30 into the trough 29, and thence through the pipe 31 to the generator-cylinder 13.

' It is obvious that a machine constructed as shown and described has no parts, such as valves, liable to get out of order, and therefore after the first cost there will be no expense to keep the machine in proper working condition, and; further, in view of the great amount of water seal employed-there can be no possible escape of gas into a room, excepting consumed at the burners.

Having thus described my invention, I

Patentv 1. A gas-machine, comprising a tank, a bell mounted to move vertically therein, a generator-dome on the bell and consisting of inner and outer walls spaced apart to provide a water-space, a-cover for the dome, a pipe leading from the interior of the dome through the Water-space and to the interior of the bell above the water-level thereof, a valve in said pipe, a vent connecting with said pipe and movable in the tank, a pipe leading from the generator to the bell, a drip-pipe leading from the service-pipe into a tub adapted to contain liquid, a blow-off pipe extended upward in the tank, a pipe carried by thebell and surrounding said blow-oft pipe, a drip-pipe leading from the blow-01f pipe into said'tub, and

a blow-otfpipe leading from the said pipe car-- ried by the bellto a pipe connection between -the generator and the bell, substantially as specified.

In testimony whereof I have signed my two subscribing witnesses.
