ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed October 6,1904. Serial No. 227.237.

To all whom, it may concern:

Be it known that I, AUGUSTUS E. SoHLIn- DER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specificatron.

This invention relates to acetylene-gas generators of that type in which the calcium carbid is automatically fed to the water-receptacle or gas-generator in accordance with the consumption of gas.

The objects of my invention are to provide improved means whereby the refilling of the carbid-receptacle is prevented when the feed opening or outlet thereof is open, to provide a simple and effective agitator for the carbid, and to otherwise improve on gasgenerators of this type whereby high efficiency and simplicity and economy of construction and operation are attained.

To these ends the invention consists in the novel construction, arrangement, and combination of parts to be hereinafter described, and particularly pointed out in the subjoined claims.

In the drawings, Figure 1 is a central vertical elevation of my improved generator. Fig. 2 is an enlarged vertical section of the lower end of the carbid-receptacle and the neck or upper portion of the generatingchamber. Fig. 8 is a vertical section takenon line 4 4, Fig. 2. Fig. 4 is a side elevation of the mechanism whereby the carbid-agi tator is operated. Fig. 5 is an enlarged top plan view of the carbid-crit-ofi valve. Fig. 6 is a bottom plan view of the same. Fig. 7 is a view similar to Fig. 3, showing a modified form of cut-off valve. Figs. 8, 9, and 10 are enlarged vertical sections of the controllerrod which governs the opening and closing of the cut-off valve, said rod being shown in connection with the controller-lever and both being shownin different positions. Fig. 1 1 is a cross-section taken on line 12 12, Fig. 9. Fig. 12is a horizontal section taken on line 13 13, Fig. 8. Fig. 13 is a top plan view of the valvecontroller lever. Fig. 1 4 is an enlarged section taken on line 15 15, Fig. 1. Fig. 15 is an enlarged vertical section of the upper portion of the carbid-receptacle and the closure therefor. Fig. 16 is a bottom plan riew of the closure attached to the upper end of the carbid-receptacle. Fig. 17 is a top plan view of said closure, showing the same secured to the carbid-receptacle.

Referring to the drawings in detail, like letters of reference refer to like parts in the several figures.

The reference-letter A designates the gasgenerating chamber, having a gradually-tapering neck a, on which the carbid-receptaole B is secured.

O designates the gasometer, which is of the usual type, comprising a suitable fluid or sealing receptacle 0, containing water, oil, or any other suitable fluid, and a gas bell or holder 0, which rises and falls in accordance with the gas-pressure. A gas-supply pipe 0 connects the gas-generator with the gasometer.

The carbid-receptacle B may be constructed in any suitable manner, but as shown has its upper and lower ends tapered, its upper end being provided with an opening I) for replenishing the supply of carbid.

A suitable frame D is secured to the upper end of the carbid-receptacle, and formed thereon is alock-post D,having a notch, as at d, to provide an inclined bearing-face d for a lock-bar E, which is provided with an opening e between its ends to permit of its being slid over the lock-post and to be held thereon. Secured to the frame D is a bushing F, around which a rubber gasket f is placed, and bearing against said gasket is a cover F, by means of which the supplyopening in the carbid-chamber is closed. A thumb-screw G is passed through a threaded opening in the lock-bar and is adapted to be screwed against the cover F to securely lock the same. -Wl1en the thumb-screw comes in contact with the said cover, the lock-bar E is elevated, and the upper edge of the opening e engages the notch (1, formed on the lock-post and checks the further movement of the lockbar, while permitting the screw to lock against the cover.

Held in the upper end of the neck a of the generating-chamber is a hopper H, and closing the lower end of said hopper is a cut-off valve H, secured to a rock-shaftH journaled in the neck of the generating-chamber and. in a bracket h, secured to said neck. The valve H is provided with a convex valveplate having angular ends h, one of which is provided with a stub-shaft 7L2, which enters a bearing h secured to the wall of the neck a, and the other end having a socket h, into which the rock-shaft H is secured. The cutoff edge 7L of the valve-plate is curved and sharpened to a knife-edge. By this construction the carbid is fed gradually to the generating-chamber when the valve is being opened, and when the valve is being closed the valve-plate shears the carbid and prevents particles of carbid from lodging between the valve and its seat.

I designates a shaft which is journaled in the bracket h and in the neck a of the generating-chamber, and secured to said shaft is an agitator z' in the form of a star-wheel, which loosens the carbid and prevents wedging of the same in the hopper H. The said shaft I is revolved through the medium of a gear-segment i, secured to the rock shaft H and a pinion i secured to the shaft I, with which said segment is engaged. On the rocking of the rock-shaft the shaft I is revolved.

The gas bell or holder 0 has secured thereon a controller-rod J, which is guided in its movement by a guide-bracket J, secured to the fluid-receptacle c. Said rod is by pref erence formed U shape in cross-section and is provided with a transverse pin 1' and a verti cal slot j, through which acontroller-lever K passes at certain times. The said lever is secured to the rock-shaft H and comprises two sections K K the latter section being secured to said rock-shaft and the section K being pivotally connected to the section K as at k. The section K is longer than the section K and the free end thereof coacts with the controller-rod J. This construction permits the cut-off valve to be closed by hand without changing the relation of the section K to the controller-rod, which is essential when the carbid-receptacle requires replenishing, and the gas bell or holder 0 is in such position that through the medium of its attached controller-rod the controllerlever, and the rock-shaft the cut-01f valve is opened. Such manipulation prevents the escape of gas from the generating-chamber while refilling the carbid-receptacle, thereby preventing possible explosion. The pivoted section K of the controller-lever, which has its free end in engagement with the controller-rod, is provided with a stop against which the section K is held, and with a look if, by means of which said section K is locked against said stop, thereby locking the two sections together. When thus locked, the oontroller-baris operated by the movement of the gas bell or holder, which when filled and elevated to a certain point is positioned relatively to the controller-lever K, as shown in Fig. 10, in which position or when in a more elevated position the cut-off valve is closed. When the gas stored in the gas-bell is being consumed, the said bell and the attached controller-rod drops and the free end of the controller-lever K enters the slot 3" in the controller-rod, and as the controller-rod is lowered still further the said lever moves downward with the rod and causes the cut-off valve to be opened, thereby allowing a quantity of carbid to be deposited in the generating-chamber and causing generation of gas, which is led to the gasometer through the pipe 0 As shown in Fig. 11, the two sections of the controller-lever are disposed in different directions, the section K being in proper relation with the gas bell or holder 0, while the section K is swung upward and held in such position by the lock 7: When the parts are thus positioned, the cut-off valve H is closed, while the remaining cooperating parts retain the positions they assume when the cut-off valve is open, thereby preventing the escape of gas from the generator, while replenishing the supply of carbid. If for any reason the lever K is held against free action and fails to lower with the controller-rod as it enters the slot j therein, the transverse pin in said rod will engage the said lever and force the same downward, the weight of the gas-bell 0 being sufficient to overcome any binding of the valve-actuating mechanism. By this arrangement the charging of the gas-generator is assured under any condition.

, In order that the supply of carbid may not be replenished while the cut-off valve H is open, I provide means to prevent the opening of the carbid-receptacle unless the cutoif valve is closed. This is accomplished by the use of a lever L, secured to the rock-sh aft H and by providing said bar with an aperture Z, through which the lower end of a rod L projects, said rod having its lower end enlarged to prevent its withdrawal through said aperture and having attached to its upper end a chain Z, which is secured to the free end Z of the lock-bar E. When the rock-shaft H is rocked to open the gas-valve, the lever L is moved downward and in its movement engages the enlarged lower end of the rod L, thereby tightening the chain Z and drawing downward on the free end of the lock-bar E, which prevents the disengagement of said bar from the notch on the lockbar, and consequently prevents removal of thecover F.

The fluid-receptacle c is provided with a partition M near its lower end to form a fluid sealing-chamber M, which is filled with water, oil, or any other suitable fluid, and secured in an opening formed centrally in said partition is a filter N of any suitable shape, but herein shown as comprising a cylindrical casing l extending from a point near the bottom of the chamber M" to within a short distance of the upper end of the fluid-recep tacle c and having three perforated partitions n, the lower one of which has secured or formed thereon a depending hood 0, having its lower edge on a level slightly above the lower edge of the filter-casing N. Extending from the upper end of said hood centrally through the perforated partition is a gas-conduit O, which connects said hood with the gas-bell c.

The inlet of the gas-supply pipe 0 terminates in the hood 0 and is provided with a flaring open-ended head P, having itslower edge serrated, as at p, to permit the gas to pass gradually around the lower end thereof, thence up through the gas-conduit O into the gas-bell c. The head P is so positioned that the lower serrated edge thereof is slightly above the lower edge'of-the hood O, and by thus arranging the said head within the hood 0 and similarly arranging the hood within the cylindrical filter-casing the lower end of thelatter is immersed deeper in'the fluid than the lower end of the hood, which, however, is immersed deeper in the fluid than the lower end of the serrated head P. The generated gas passing around the serrated end of the head P rises above the surface of the fluid within the hood 0 and passes up through the gas-conduit into the gas-bell. In thus sealing the gas-inlet the escape of gas from the gas-bell is prevented, the pressure therein being insufficient to displace the fluid and free the inlet.

\Vithin the filter-casing N and surrounding the gas-conduit between the lowest perforated partition and the intermediate perforated partition I interpose charcoal or other suitable material, and between the uppermost partition and the intermediate partition a quantity of batting, cotton waste, or other suitable material is placed.

Entering the filtering-casing N between the lowermost perforated partition and the surface of the fluid in the chamber M is a gas-supply pipe R, which may be led to any place for use. The gas stored in the gas-bell c is forced through the filtering material and out through the supply-pipe.

A safety device is provided to allow the escape of excess pressure from the gas-bell, and it comprises a tube S, secured to and carried with the gas-bell c. Said tube is closed at its upper end and is provided with an aperture 3 near its lower end, which is immersed in the fluid in the tank 0. An escapepipe T, open at both ends, is secured with its lower end in the partition M and extends up into the tube S, and when the gas is generated excessively the gas-bell 0 will be ele vated until the aperture 8 in the tube S is brought above the surface of the fluid in the gasometer, which permits the escape of excess generation through said aperture into the escape-pipe and out through a connec tion t'thereof, which is led into the open air. The excess generation will also cause isplacement of the water in the lower end of the filter-casing and break the seal to permit the escape of gas through the lower end of the filter-casing and out through the lower end of the escape-pipe T into the open air.

In Fig. 8 of the drawings I have shown the valve II reversed, in which case the angular extensions thereof lie on opposite sides of the hopper H and the carbid rests on the concaved surface of the valve.
