ACETYLENE-GAS G EN ERATO R.

SPECIFICATION forming part of Letters Iatent No. 655,4;46, dated August 7, 1900.

Application filed October 5, 1899. Serial No. 732,611. (No model.)

To all whom it may concern:

Be it known that 1, JOHN LAWRENCE, acitisuch as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in acetylene-gas generators; and the object of the invention is to simplify and improve the construction and increase the efficiency of the machine.

To this end the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical section of my improved acetylenegas generator. Fig. 2 is a similar view taken at right angles to the section shown in Fig. 1. Fig. 3 is a detail perspective View of the carbid-basket removed from the bell. Fig. 4 is a detail view of the mouth of the hell, with a portion of the wall broken away to show the condenser-chamber. p

In the drawings the same reference characters indicate the same parts of the invention.

1 denotes the tank, and 2 the bell.

3 denotes a relief-pipe which forms a safetyvalve in the event of the gas generating faster than it is consumed. The relief-pipe 3 is formed integral with the bell 2 and projects slightly through the top of the same, as shown in Figs. 1 and 2;

4.- denotes the condenser-chamber fixed in the mouth of the bell; and it consists of horizontal plates 5 and 6, which form the parallel top and bottom of the condenser, the bell forming the curved wall thereof and the plate '7 forming the straight wall, the condenserchamber being air-tight with the exception of the inlet-pipe 8, which extends above the carbid-basket 15, and the outlet-pipe 9, which extends up through the top of the bell and terminates in a stop-cock 10. In practice the condenser-chamber may be made separate caped.

and complete and afterward removably attached to or soldered in the bell.

12 represents a socket fixed to the inside of the bell, and 13 denotes a bracket removably secured in said socket. The upper end of the bracket terminates in a horizontal arm 14, to which the carbid-basket 15 is fixed.

The operation of the device is entirely automatic and simple. The carbid-basket is first charged and then inserted in the bell, which is conveniently done by tilting the bell, so that the basket will enter the mouth of the bell between the straight wall of the condenser-chamber and the curved wall of the bell and the bracket inserted in the socket in the bell.

The bottom of the carbid-basket is horizontal, and it will be noted that the horizontal arm of the bracketextends across the cen-- ter of the bottom of the carbid-basket to act as a brace and prevent the basket sagging at the bottom.

In operation the tank 1 is partially filled with water about two-thirds full. The bell 2 is then placed within it, and the air-cock 10 is opened, permitting the air to escape from said hell 2 through the pipe 9, the stop-cock 10 being again closed after the air has es- The bell 2 will then sink by its own weight until it is stopped by the stop-cock 1O engaging the top of the tank 1. A'sufficient quantity of calcium carbid is then placed in the carbid-basket 15, which as soon as the calcium carbid comes in contact with the water generates the gas which fills the bell and is permitted to'escape at the stop-cock 10 for consumption, except when the gas is being generated faster than it can be consumed,

when the surplus gas escapes through the reis' claimed, and desired tobe secured by Let ters Patent of the United States, is-

In an acetylene-gas generator, the combination with the tank 1, of the hell 2 provided said bell 2 and terminating at its upper por tion in the horizontal arm 14; and the carbid- I basket 15 fixed to said horizontal arm 14; substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

with the outlet-pipe 3 supported in its top portion and projecting through the same; the condenser-chamber 4 at the bottom of said bell 2; the inlet-pipe 8 connected with said condenser-chamber and opening within the upper portion of said bell; the outlet-pipe 9 connected at its lower end with said con- Witnesses:
