i 'l' TN ACETYLENE-G-AS GENERATOR.

To all whom it may concern:

Be it known that I, MELVIN S. MIsHLER, a citizen of the United States of America, residing at Little River, in the county of Dade and State of Florida, have invented new and useful Improvements in Acetylene- Gas Generators, of which the following is a specification.

This invention relates to acetylene gas generators, and the object of the invention is to produce a device of this class which shall be simple in construction, efficient in operation, in which the operation shall be to a large extent continuous and automatic, and in which the charges of carbid may be readily renewed or replaced whenever necessary.

Vit-h these and other ends in View which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifica.- tions within the scope of the invention may be resorted to when desired.

In the drawings, Figure 1 is a vertical sectional view of a device constructed in accordance with the invention, the position shown being the one occupied when one of the carbid charges is practically exhausted, dotted lines being shown to indicate the position when the tank cont-aining the exhaust charge is raised for the purpose of renewing the charge. Fig. 2 is a vertical sectional view showing the device in active operation. Fig. 3 is a sectional view taken on the line 3 3 in Fig. 1. Fig. L1 is a horizontal sectional view taken on the line 4:-4 in Fig. 1. Fig. 5 is a vertical sectional detail view illustrating a slight modification.

Corresponding parts in the several figures are denoted by like characters of reference.

1n the construction of the improved generator there is employed a tank 1, oreferably of sheet metal of cylindrical shape, sa id tank being reinforced adjacent to its upper edge by a cast iron rim 2. Suitably connected with said tank, preferably at diametrically Specification of Letters Patent.

opposite sides, or approximately so, are U-shaped pipes A, B, the bends of which 3 and 4 extend through the wall of the tank adjacent to the bottom thereof. The limbs 5 and 6 of these U-shaped pipes which are inside the tank extend nearly to the upper edge thereof. The limbs 7 and S which'are located outside of the tank are to be connected respectively with the burners of the system and with the atmosphere. The pipe S, however, may, if preferred, be connected with a storage tank to avoid waste of gas.

The pipes A and B are provided with pet cocks 9, 10 for convenience in draining from said pipes any water that may accumulate therein owing to evaporation and condensation. The inverted vessel or bell C which operates in the tank 1 is of such shape and dimensions as to be guided freely within said tank, the walls of the bell being slightly spaced from the walls of the tank. The top plate 11 of the bell is equipped with tubes D, D2 of relatively large diameter extending therethrough, said tubes being provided with ports or openings 12 located a suitable distance below the top plate 11. Valves 13 which operate by gravity to obstruct the ports l2 are hingedly supported adjacent to said ports, and said valves are provided with operating rods 1/1 extending through the ports so as to lie in the path of the carbid tanks E and E2 which are accommodated in the tubes D, D2. A flange or casing 15 of suitable construction extends upwardly from the top plate of the bell and surrounds the tubes D, D2, the intermediate space being partially lled with water which forms a seal when the flanged covers F, F2 are in position, said covers being independently removable so as to constitute closures for the tubes D, D2. Each of the covers is provided with a handle 16 and with a pet cock 17, and suitable stop means in the nature of hooks 1S are provided to retain the covers in position against the pressure of the gas that is being generated within the tank. v The bell is also provided with tubes 19 of relatively small diameter extending from the top plate 11 downwardly into the tank, said tube serving to guide the lifting rods or adjusting rods 20, each of which is provided with a handle 21 to limit its downward movement, and each of which is also provided with suitable adjusting notches 22, Q3 adapted to engage a stop member 24 upon the top plate of the bell, whereby the lifting rods may be retained in adjusted position, said notches 22 being relatively near the upper ends of the rods. The lower ends of the lifting rods 20 are bent upwardly to form legs 25 extending within the tubes D, D2, said legs having terminal brackets 26 carrying anti-friction elements such as wheels or rollers 27 engaging the inner faces of the walls of said tubes. The knees 28 formed by the angles produced by bending the legs 25 to form the brackets 26 abut upon the bottom sides of the carbid tanks E, E2 which are thereby supported. Said carbid tanks have bottom apertures 29 to admit water from the outer tank 1 to the contents of said carbid tanks.

rIhe tank 1 is provided near its upper edge with a filling spout 30 communicating with an aperture 3l through which water may be admitted into the tank, the normal water level being indicated in Figs. 1 and 2 of the drawings. The bell C is also equipped with a sealing member 32 consisting of a cylindrical tube closed at its upper end, the same surrounding the limb 6 of the exhaust tube B which provides for the overflow of gas to the atmosphere or to a storage tank, as hereinbefore stated.

rllhe supporting notches 22, 23, and the handles 21 of the rods 20 are so located that when the bell is at the lowermost position, as shown in Fig. 1, and the rod 20 is lowered until the handle 21 rests upon the top plate of the bell. the carbid tank supported by the limb of such rod will be submerged., as shown at E2 in Fig. 1. Vhen the rod 2O is raised to the first notch 22, the carbid tank will be supported slightly above the water level, as shown at E in Fig. 1. By lifting the rod unt-il it is supported by the second notch 23, the carbid tank will be elevated to a point where it may be readily reached and removed for the renewal of a charge, and this position has been indicated in dotted lines at E2 in Fig. 1 and in full lines at E in Fig. 2, the latter figure showing the carbid tank E2 lowered to the same position which is indicated in Fig. 1, the bell C being, however, shown in a raised position indicating the generator to be partly filled with gas. Normally it is intended that the carbid tanks shall occupy the relative positions shown in full lines in Fig. 1. /Vhen one of the tanks is submerged, gas will be generated, thus lifting the bell with its attachments until both tanks are above the water level. As the gas is being consumed, the lowermost carbid tank will again become submerged, gas will be generated, and the bell will become elevated, and this operation will be repeated until the charge is exhausted. Should this occur afterV dark when it is not desirable to approach the generator with a light, the generator may be restored to active position by simply changing the position of the carbid tanks, lifting the one which contains the exhausted charge and lowering the one containing a fresh charge, when the operation of generating gas will continue uninterruptedly. To replace a charge of carbid in either tank, said tank is lifted by means of the lifting rod 2O until the second notch 23 of said tank engages the stop member 24, as will be seen at E in Fig. 2. The pet cock 17 attached to the cover of said tank is then opened, and the cover is removed, after which the tank may be lifted out, the spent contents emptied and a fresh charge inserted. The cover of the carbid tank is then replaced, and such tank is then lowered until the notch 22 of the supporting rod engages the stop member 2st, the pet cock is closed, and the machine is again ready for operation. By this arrangement it is obvious that the operation of recharging either carbid tank may be performed by daylight, it being understood that the proportions are such that the charge contained in one carbid tank will be suiiicient to furnish a normal gas supply for twenty-four hours, or approximately so.

Should the quantity of gas generated exceed the requirements of the system, the bell will be lifted until the lower end of the closure member 32 reaches the water level or a point slightly above the water level, when the surplus gas will escape through the tube B, the discharge through said tube being automatically checked as soon as the bell descends suiiiciently to cause the lower end of the closure member 32 to become obstructed by the water contained in the tank 1. In Fig. 5 of the drawings has been illustrated a slightly modified form of the vent or safety tube which in this instance has been shown as consisting simply of a tube 35 extending through the top plate 11 of the bell C, the lower end of such tube being so disposed as to reach the water level, thus becoming unsealed when an eX- cess of gas is generated. Escaping gas may be conveyed through the tube C and any suitable connections to the atmosphere or t0 a storage tank.

It will be observed that the valved openings 12 of the tubes D, D2 are so located that when the carbid tank contained in either of said tubes is lowered to its lowermost or to an intermediate position, the valve 13 will be opened owing to the stem 14 being engaged by the wall of the carbid tank, thus establishing communication between the interior of the tube and the space bounded by the outer tank, the bell and the water line. Vhen either carbid tank is raised to the position at E in Fig. 2, for the purpose of renewing the charge, the valve will close by gravity and will be held closed by the pressure of gas within the generator, thus preventing escape or waste of gas while the carbid tank is being removed for the renewal of the charge.

Having thus described the invention, what is claimed as new, is

l. In a device of the character described, an outer tank, a bell movable therein, tubes extending through the top of the bell and having ports, gravity valves supported adjacent to said ports, carbid tanks movable in the tubes, means for supporting` said carbid tanks in upper, lower and intermediate positions, stems connected with the valves extending through the ports and lying in the path of the carbid tanks to open the valves when the tanks are in the lower or intermediate positions, and sealing covers for the tubes.
