Be'it known that I, ELMER E. TAGGART, a citizen of the United States, residin in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Acetylene-Generators, of which the following is a specification. The invention relates to means for roducmg acetylene gas and more particularl y to apparatus for use on shipboard.

The'object of the lnvention is to offer a simple, inexpensive apparatus, easily and economically installed and maintained, which shall be efiicient and eminently safe inits operation.

. The invention consists in certain novel features of construction and arrangement by which the above objects are attained, to be hereinafter described. y

The accompanying drawings form a part of this s ecification and show approved forms of t e invention.

Fig; 2 is an elevation of tlielgenerai 3 is a vertical section on a larger scale, p artly! in elevation, with the funnel-shaped part1- tion omitted showing the means for controlling'the deliveryof the carbid.

nected by links D D in the generating cham er E.

Gas generated by contact of the carbid with the water escapes through the deliverv pjlpe E and branch E controlled by a cock 3 to the interior of a small gas-holder or pressure regulator F consisting of an open topped casin p rtially filled with water and containing a e 1 F"w1thin which the branch pipe E terminz' 'te and adapted to rise and sink as the as p 'essure varies. From the top of the be 1 ext nds a link F ivoted to a lever E?! on the (ink E? whereby the flow from the generat is controlled and the gas passing from-the nterior of the bell through theservicepi e i automaticallymaintained at the desired se ice pressure.

The pi e E is preferably extended to a considerable .hei t and is provided with a I descending branc i or leg E serving as a relief pipeconnected to the Water pi e B'f on the sea side of the sea-cock'B or ot ierwise leadin to the water outside the hull of the vessel.

he operation of the apparatus is as follows:Assu ming the sea-cock B to be closed, the screw-capC is removed and a jcarbid introduced, retained by the gates gravity of the float D, and the cap rep aced (and again tightly seoured- The sea-cock is 't'liien opened and water enters the tank, rising in the lattef'until the pressure of the imsufficiently to lift the the carbid; the trot with the water generates latter by co 0 gas as usual, v eproduction contmuing until the-gas pressure is great enough to force dowh th water level in the tank and through the gra i'ty of th float again to .close t e gates. as thus generated flows thropgh the pipe E and branch pipe 1L mtothe bell F which rises as the'service ressure is exceeded and shuts the gas 000 E until the service pressure again falls. When the ressure o f gas in the tank falls the water .lprisoned .air o gas} eguals that induced by evel again rises and a fresh supply of carbid is de- 7 down the water level.

pipe B7 each outflow carries withi-t v'rtiated water and. spent. carbid delivered at the mouth .of

newing the water.

the pipe by the inclined bottom-B of the H is a draw-off cock by which the water level in the generating chamber can belowereel sufliciently to insure the closing of the carbid orifice c in re-charging with carbid after the sea-eoe'kflhas been shut'ofl', and J is a circular gratirig": r latform secured to the bottomB beneath t e opening in'the float to receive the carbid as it falls and provide a resting place therefor during decomposition.-

K is a cap forming a water seal for the 0 en end of the branch pipe E within the bel F to prevent the return of gas from the bell and service pipe.

' The leg E of the pipe E is sealed by water standing therein at thesame level as in" the tank B andis always openyits function is to rovide a harmless escape for gas to the exterior of the-vessel if excessive pressures are accidentally developed in the tank through excessive feeding of carbid. The pipe E and leg E are extended above the water line of the vessel so that when the screw-ca C is removed water cannot enter through tliese pi esand flood the tank.

l 11 order to guard against flooding by inadvertently removing the screw cap before closing the sea-cock, a safety device for these parts of the apparatus may be employed; a simple mechanism for this purpose 18 shown consisting of a chain L from the lever B of the sea-cock to the screw-cap and extendingthrough a lug L on the upper part of the tank having a keyhole-slot Z therein." The chain is of such length as to prevent the removal of the cap while the sea-cock is in the open condition, and the slot is so shaped as to permit the chain to be passed therethrough, aided by the hands, when sufiicient slack is furnished by shutting off the sea-cock to allow the cap to be unscrewed. The engagement of the chain with the slot holds-the sea- -'cock in the'closed condition until the cap is re-a plied and the chain again drawn through the arger portion of the slot to supply the slack required to permit the re-opening of the sea-cock.

Other safety or tell-tale means may be eniployed for this or other portionsoi the apparatus or by exercising care the a paratus may be operated without them, an modifications oi the forms and proportions of the parts may be made without departing from the principle of the invention, the essential features of which are the tank with tightly closed to and open communication from the bottom t ereof to the water in which thevessel floats or is submerged.

It will be noted that the tank is secured to the vessel and that the usual floating bell with its water seal is ehmmated- The vanaflow ofwater in one direction or the othertions i-n'spaee required by variations in volume of gas generated are provided by changes of water level inthe tank, and each alternate change of water level induces acorresponding through the water pipe B Thereisno open-. l

ening'throughwhichgas can escapeyfrom the generator to the interior of the vessel; the" pressure regulator controls the flowto the service pipe and any excesspressure is harmlessly relieved through-the pipes leading to the water outside-the hull, r r

Importance is attachedto the location of the pipefE relatively "to. the water level in the tankand the dischar e orifice from the carbid chamber. I When the supply of carbid is exhausted and'the gas pressure reduced by i consumption, the waterlevel in the ta'nk'will tend to rise to the water line of the vesselunless the sea-cock B be elos edjby locatin the entrance to the pipe E below the carbi chamber and above a line, reached by the water level in its normal fluctuations any further rise covers the end of the pipe E imprisons the remainin gas in theupper ortion of the tank, an canonly rise to a evel at which the pressure of the compressed as equals the pressure due to height of water inc, and the parts are so thus to check the rise be ore the water reaches the carbid chamber.

roportioned as It is also important that the branch pipe E extend above the water linetolinsure against possible flooding of the pressure regulator and service ipe.

The tank will usua y relieve itself of ex: cess pressure through the 'ipe B but if the sea-cock be turned to the s ut position while reli pipe E still permits excess gas to escape harmlessly. i
