To all whom t may concern:

Be it known that I, GEORGE E. CHANDLER, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a certain new and useful Improvement in Acetylene- Gas Generators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in acetylene-gas generators.

One object ofthe invention is to so construct a generator wherein acetylene gas can be generated that feeding of the calcium carbid is positively prevented when the generator is open to the atmos here.

Another object o the invention is to so construct a feed-controller for controlling the feeding of calcium carbid that the same is rendered inoperative by the opening of the generator.

Another object of the invention is to improve the construction of the carbid-feeding mechanism.

Another object of the invention is to irnprove the construction of the machine with relation to the prevention of the escape of gas into the atmosphere from the various Joints or connections.

Other objects of the invention will appear from the description and claims.

The invention consists in a gas-generator rovided with a feeding device, a controller or such feeding device, and means for holding the controller in an inoperative position while the generator is open.

The invention also consists in the construction of the controller and in the combination therewith of means for rendering the controller inoperative.

The invention also consists in the construction of the feeding device.

The invention still further consists in the general novel features of construction of the machine and in the peculiar combination of parts, as shall hereinafter be more fully described, and ointed out in the claims.

Figure 1 o the drawings represents a front elevation of the improved acetylene-gas machine, portions thereof being broken away to more clearly illustrate the construction of some of the parts. Fig. 2 represents a plan view of the same. Fig. 3 represents a detail side view ofthe counterweighted lever and connecting parts. Fig. 4 represents an enlarged sectional view of the feeding device and its coperating mechanism. Fig. 5 represents an enlarged cross-sectional view of the casing for the feed-lever and its shaft; and Fig. 6 represents a vertical sectional view of the upper portion of the hopper, showing the construction of its neck and the closure thereof, taken on a line at right angles to that shown in Figs. 1 and 4.

Similar characters of reference designate corresponding parts throughout.

In carrying this invention into practice my main object has been to prevent the escape of gas into the atmosphere whether such esca e is occasioned by leaks in joints of the mac -ne .in which movable parts are mounted or from failure to close an opening through which gas may escape, my other objects, of equal importance therewith, being to improve the general construction of the machine.

In the drawings, 5 represents the gas-generating chamber, having the feeding-drum 6 furnished at its top portion with the carbidsupply-opening fitting 7, closed by the cap 8, screwed thereon. This chamber 5 is preferably mounted on a base 9 and is provided with a clean-out 10 of anyusual construction.

The construction of the supply-fitting 7 is more particularly shown in Fig. 6, which shows the channel 7 formed in the wall of this fitting and connecting with the upper end thereof, the cap 8 being furnished with an annular compartment 8', in which gas in passing toward the joint between the cap 8 and the fitting 7 may be led to the upper end of the channel 7.

Within the drum 6 is mounted the hopper 11, from which extends the contracted portion or tube 12 and the frame 13, on the bars 14 of which is sustained the cone 15, positioned beneath the portion or tube 12, and on this tube 12 works the tubular feed gate or valve 16, having pins, as 17, or their equivalents, the lower end of this tubular gate 16 Aresting on the cone 15.

From the drum 6 depends the cylinder 18, having an open end around which is fixed the plate 18, having the depending rims 19 19 furnished with serrated edges.

At the side of the chamber 5 is mounted the water-supply inlet 20, connecting with said chamber by a suitably-trapped supplypipe 21 and provided with the gas-escape pipe 22.

IIO

On the drum 6 is secured the casing 23, which connects with the interior of the drum, and in this casing is pivoted the arm 24, having a forked end engaging under the pins 17 17 and provided with the exterior lever 25, having the weight 26 and the roller-bearing 27. The casing 23 is formed and packed to prevent the escape of gas in the manner shown and is provided with the gas-escape pipe 28, connecting with a similar pipe 2S), leading from the channel 7 of the fitting 7, whereby the gas escaping from these parts is conveyed to the main escape-pipe 30, by which it is directed into the atmosphere outside the building in which the generator is stationed. Reference to said figure will show that the casing 23 has a compartment 23, with which the pipe 28 connects, the shaft 24 of the lever 24 being journaled in the casing and compartment and carrying the disks 242 and 243, the latter being movable, and the spring 244, which tends` to force these disks apart and against the walla of the casing and its compartments to more fully close the shaft-bearings therein, as these disks can. be more accurately vfitted than can the shaft, the lever 25 being litted and secured onto the outer end of the shaft 24.

The gas-storage mechanism comprises a casing 31, having the compartment 32, connected by the pipe 33 with the drum 6, and having the pipe 34, leading upward, the partition 35 in this casing supporting the pipe 36, open at its ends and connected with the outer gas-main 37. Extcriorly this casing is supplied with the inlets 38 and 39, the waterlevel below the partition 35 being indicated by the line a c, while the water-level above said partition is indicated by the line b' b.

The gas-escape 30 connects with the compartment of the casing'31 below the partition. 35 to provide for the escape of gas reaching this compartment. i

Within the casing 31 movable the inverted bell 40, having` the top 41, and the inner gas-bell 42, having openings, as 43 43, and covering the open ends of the gas-inlet pipe 34. In the top 41 is secured the tube 44, which works over the guide-rod 45, fixed in the partition 35.

From the upper end of the pipe 33 and partially sustained by the bracket 46 of the casing 31 extends the standard 47, carrying the pivotally-mounted counterweighted lever 48, one arm of which is connected. with the lever 25 by the wire 49, which works through a perforation in said arm and has its lower end enlarged to limit its movement independently of said lever 25.

From any suitable and ordinary support, of which 50 is a part, depends the bracket 51, in which the lever 52 is pivoted, one end of this lever being connected by the connection 53 with the weighted end of the lever 48, while the other end of said lever 52 is flexibly connected by the connection 54 with the cap 8 for closing the carbid-supply opening 7.

The hopper 11 is usually recharged with calcium carbid before the previous charge therein `is wholly exhausted. To effect this recharging, it is necessary to remove the cap 8 from the fitting 7. If now the feeding of the carbid from the hopper into the water contained in the chamber 5 be continued, gas would be generated and a large portion thereof would escape through the opening of the YIitting 7. In order that the continued generation of gas should be prevented, I connect the cap 8 with the feeding-control device, preferably as shown in the drawings, whereby the weighted end of the arm 48 lifts the arm 25 of the feed-control mechanism to thus depress the yoke 24 from any possible lifting action on the feed-gate 16 and to sustain these parts in such inactive position until the cap 8 is replaced and the escape of gas is prevented.

After the supply of calcium carbid has been placed in the hopper 11 and the cap 8 has been screwed into place on the fitting 7 the gas-bell 41 is generally at or about its lowest point of movement, and the downward movement of the arm 25, until the bearing 27 rests on said tank, causes .the proportionate lifting of the feed-gate 16, thus permitting a predetermined amount of carbid to fall from the cone 15 in annular distribution into the water contained in the chamber 5, the action of the water on said carbid generating gaseous globules, the specific gravity of which being less than that of the water causing them to rise toward the surface of the water. In their upward movement these globules are successively disrupted as they drag over the serrations of the lips 19 and the undissolved matter therein liberated for further action by the water. The gas thus generated accumulates between the lower portion of the chamber 6 and the upper portion of the hopper 11 and then enters the pipe 33, passing into the compartment 32 of the storage-tank and thence through the pipe 34 into the chamber 42 of the gasbell 41 until the accumulation of gas in such chamber causes the lifting of the bell to the point where the feed-controller permits the feed-gate 16 to close.

From the upper part of the bell 41 the gas passes down the pipe 36 and into the servicemain 37, from whence it is distributed to the various points of use.

By the connections from the several joints where any escape is possible the escaping gas is conveyed by the pipes 28, 29, and 30 and by the pipe 22 to the exterior atmosphere.

Vhen the gas-bell is lifted by undue pressure of gas to bring the openings 43 above the water-level l) l), the gas escapes from the inner bell into the outer bell and passes down through the pipe 55 (more clearly shown in TOO Fig. 5 of the drawings) to the compartment below the partition 35 and is thence conveyed to the outer atmosphere by the escapepipe 30.

Having thus described my invention, I claim as new and desire to secure by Letters Patent` 1.
