HARTWELL WILLIAM WEBB, OF NEW YORK, N. Y.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 749,007, dated January 5, 1904.

Application filed March 18, 1903. Serial No. 148,418. (No model.)

To all whom it may concern:

Be it known that I, HARTWELL WILLIAM- WEBB, a citizen of the United States, residing at New York, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Generators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to gas-generators, especially of theacetylene type. Its object is to provide a generator which will furnish a large volume of gas and be particularly useful in connection with vehicle-lamps-as, for example, lamps for heavy automobiles.

To this end it comprises two communicating generating elements, as a carbid receptacle and a surrounding water chamber, means for creating a capillary film of water, means for regulating the supply of water, safety-escapes for the gas, and details of construction.

In the accompanying drawings, Figure 1 is a central longitudinal section. Fig. 2 is a central transverse section, and Fig. 3 is an end elevation. v 1 represents the water-chamber, which in the preferred form I have illustrated is substantially rectangular, inclosing a substantially cylindrical carbid-receptacle 2. The carbid-receptacle is closed at each end by means of caps 3. These caps, as illustrated, comprise a body l and a flanged and corrugated or screw-threaded inner lining 5, the flange taking over the body 4.. In the head of the cap is a gasket or packing 6, secured in place by a flanged plate 7.

8 is a projecting head similar to a bolthead adapted to receive a ,wrench.

In each end the water-chamber has a cir cular depression 9. The carbid-receptacle is preferably formed, as shown, by a cylindrical sheet of metal soldered to an inturned flange of the water-chamber. Secured at each end to the interior of the carbid-receptacle is a flanged cylindrical and screwthreaded ring 10 to receive the cap 3, preferably braced by a wire ring 11 under the top flange of the threaded ring 10.

Within the carbid-receptacle 2 is a curved plate 12, slightly separated by means of indentations 13 from the bottom of the carbidreceptacle so there is formed a capillary space 14. In the bottom of the carbid-receptacle and below the plate 12 are perforations 15, which lead into a small chain ber-a waterbasin formed by a semispherical plate 16.

A tube or guide 17 passes through the water-chamber and the carbid-receptacle and is attached, by means of a screw-thread or other means, to a valve-seat 18,which projects through the bottom of the carbid-receptacle into the water-chamber and has four ways or ports 19, 20, 21, and 22. Passing through the tube 17 is a needle-valve 23, screw-threaded at the top at 24 and having a hand-wheel 25. head 26, and for a short distance above the head is reduced, as shown at 27, so as to form. between it and the valve-seat 18 a capillary space 28, which has its continuation through the tube to the top terminating or discharg-- ing' at the ports 29'.

30 is a port or. passage-way leading from At the bottom it has the usual pointed the carbid-receptacle into a combined gas I,

pipe and condensing-tube 31, which passes through the water-chamber from end to end and terminates in the gas-discharge 32, governed by the usual cook 33.

34 is a feed-spout through which the wan-r is introduced into the water-chamber. It carries as a stop a screw-cap 35, which bears a depending perforated strainer 36 and extending above it a small-discharge-pipe 37, forming a safety-escape for the gas.

39 is a filter-holder.

The generation of the gas proceeds upon J the principles set forth in my copending application, Serial No. 138,156, filed January 7,

1903, in which I have broadly claimed meansfor creating a capillary film and presenting it to the carbid and which it is purposed to haveissue of even date with this application. Water is placed in the chamber 1 through the spout 34:. The valve 23 is turned so that its head 26 is drawn away from the port 19. The water enters the basin or chamber 16 through the ports 19, 20, and 21 and thence passes to the capillary space 14 by the perforations 15. A capillary film of water is carbid in the chamber 2.

the passage 30 and thence by the condenserpipe 31 to the discharge 32, to which may be attached a rubber tube or other connection. The water of condensation will fall into the carbid-receptacle, but in such a manner as merely to accelerate the generation. I have provided alternative safety-escapes for the gas. If with the water-valve 23 and its head 26 lifted to admit the water the cock 33 should be closed, cutting off the discharge of gas, the gas generated will force its way out through the water-passages into the Water-chamber and escape by the strainer 36 and the pipe 37. When the valve-head is down, as shown in the drawings, the water previously admitted to the basin or chamber 16 and the capillary space 14 will have the pressure of gas behind it to resist its (low into the chamber 2 and will then the more readily follow the capillary space 28, finding its exit at 29, thus withdrawing the supply of water and cutting oi? the flow of gas whether the stop-cock 33 be turned or not. This combination of safety devices renders it practically impossible to approximate an explosive force in the generation.

I have so applied the caps 3 that they cannot be readily removed and, in fact, require a wrench to remove them as a precaution against tampering.

The relations of the substantially rectangular water-chamber and the inclosed substantially cylindrical carbid-receptaole are such that I secure a generator readily and firmly fixed in place on a vehicle, for example, and giving the best arrangement for the carbid-receptacle to permit a large supply of water and the immediate action of the capillary film over a large area of carbid. The construction is also a strong one, and I augment this by the manner in which I apply the caps, making them practically flush with the body of the generator.

I have used the terms water-chamber and carbid-receptacle, &c., in this specification and 'in the claims as illustrative and as examples of relative generating elements.

It is to be understood that my invention is broadly applicable to generating elements and to other relative arrangements or modifications thereof by which a liquid is brought into contact with a solid to generate a gas.

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

1. In a gas generator, in combination a water-chamber, a carbid-receptacle, perforations in the carbid-receptacle communicating with the water-chamber,and a plate lying over the perforations and forming with the body of the carbid-receptacle a capillary space.

2. In a gas-generator, in combination a water-chamber, a carbid-receptacle, a plate in the carbid-receptacle and slightly separated from it, a water-basin attached to the bottom of the carbid-receptacle and ports leading from the water-chamber to the water-basin, and ports leading from the basin to the space between the carbid-receptacle and the plate.

3. In a gas-generator, the combination of a carbid-receptacle,a water-chamber surrounding the carbid-receptacle, a plate in the bottom of the carbid-receptacle forming therewith a water-space, a valve and valve-seat passing through the plate and the carbid-receptacle, ports in the bottom of the carbidrecept-acle, a water basin embracing the valve-seat and the ported part of the carbidreceptacle, and a passage from the waterchamber into the valve-seat.

4. In a gas-generator, the combination of a water-chamber, a carbid-receptacle, a waterbasin, and communications, with a needlevalve and tube forming a capillary space and leading to a discharge-port.

5. In a gasgenerator in combination, a water-chamber, a carbid-receptacle, a waterbasin attached to the bottom of the carbid-receptacle, communications between the waterchamber and the water-basin and between the basin and the carbid-receptacle, and a plate forming with the bottom of the carbidreceptacle a capillary space.

6. In a gas-generator, in combination a water-chamber, a carbid-receptacle, communications between the two, a capillary space leading into the ca bid-receptacle, and a capillary space leading from the communications to an outer exit.

7. In agas-generator, in combination a substantially rectangular water chamber, a substantially cylindrical carbid-receptacle, valved communications between the two, and a screw-cap at each end of the carbid-receptacle fitting in a depression in the head of the water-chamber.

In testimony whereof I affix my signature in presence of two Witnesses.
