' Application filed July 1l, 1899. Serial No. 723.499. (No model.)

y To a/ZZ whom, it may concern/.-

Be it known that I, CARL WILHELM SDER- BERG, a citizen of Norway, anda residentof Nordstrand, near Christiania, Norway, have invented certain new and useful Improve? ments in Apparatus for GeneratingAcetylene Gas, of which the following is a specification.

My invention relates to apparatus for generating acetylene gas, and more especially to that class of such generators in which certain quantitiesof calcium carbid are from time to time bymechanical means thrown into a body of water contained in a icloscd vessel communicating withan expansible gas-reservoir.

The object of my invention is to provide an improved apparatus of this kind which is simple in'fconstruction and operation and which is so constructed and arranged that no air can possibly enter the generator' when the apparatus is charged with new carbid and so no gas can escape during charging operation.

It is also the object of my invention to so construct the apparatus that the moving'or.

operating parts of the same are out of cont-act with the gas, whereby they are prevented from becoming corroded by the action of the gas and whereby easy access to the saidparts may be had. l

My invention consists in thev combination,

' with a container for water having a number of carbid-receptacles placed on its top, of movable covers closing said receptacles to the'interior of the water-container andof vmeans for automatically opening and closing said covers through the action of the vertical movement of the expansible gas-reservoir;`

and it also consists in certain special features of arrangement and construction whereby the aforesaid objects are attained.

In order to fully explain'my'invention, I have shown in the accompanying drawings an apparatus constructed in accordance with my invention; but it is tobe understood that the apparatus shown` is only one of the forms which the same'may be given.

In the drawings, Figure l represents a side elevation, partly in section, of the said improved apparatus. Fig. 2 is a horizontal plan of the same. Fig. 3 is a detail view of one of the carbid-containers. Figs. i and 5' are rea and the gasometer h. The gas-generator a consistsof the waterreservoir,`which is funnel-shaped below, as shown at et', and is providedwith the discharge-pipe g,'said resvervoirbeing filled with water to`about three- "fourths/'ot' itsheight and closed above in gasproof In'anner by a top a2 and wall a3, depending into the water,-for1ning a water seal. From this wall extends inwardly and downwardly a deiiecting-wall a4, the lower edges of -thiswalland the wall a3 contacting with the supplemental perforated bottom a5. By means of atube o running-into the upper partqof the generator the acetylene gas collecting over the water is fed to the gasometer b. This maybe ofthe ordinary or any desired construction and comprises a body h and movable bell h', the latter being guided by antifriction-rollers bbearingfagainst vertical posts-or rods 198. -0nthe'upper part' of the gas-generator a number offreservoirs A are arranged. Nine of these are shown in the drawings for purposes of illustration. They serve as recipientsforv the carbid. These receptacles are locked'- in gas-proof manner above by a lidor cover A', secured in place ,bya suitable clamp A2, while a lid B, which lcan be opened, is closely pressed against the lunder side.' Under each carbid-receptacle A, vwhich is reduced somewhat vtoward the upper part for the purpose of betterrelease of the carbid, a cylinder Lis sitnated'which reaches through the top a2 ofthe generator vessel ct and extends somewhat below the level of the water. The lids or covers B, which close the lower ends of the carbid-reservoirs,

have each on their axle or shaft C, on which they rock, a weighted lever D, which rests with its lower edge d on a disk G, which is pivoted on a pin F on the top a2 of the generatorcasing a. This dish or plate Gr is IOO when the bell b' sinks. In this action the edges d rub on the disk G, so that the lids B of the carbid-reservoirs are constantly kept locked by the revolving disk G. This disk G is provided with an opening IFI,which when it reaches a position under the lever D of al cover B allows the lid B to open, as the disk D and the weight of the lid B causes it to fall, thus opening the carbid-reservoir. The contents of the carbid-reservoir A fall into the water vessel a. It is apparent from the above that with every descent of the bell b a carbid-receptacle A is opened and the contents thereof discharged into the water-reservoir a. The contents of a carbid-receptacle A will develop an amount of gas equal to the quantity required to fill the gasometer. The revolution of the disk or plate G occurs only at the descent of the receiver or bell b', while it stands still when the same ascends upon introduction of carbid in the water. This action of the mechanism is d'ue to the manner in which one of the toothed wheels N or O is mounted on its axle, one of kthese wheels being not keyed to the axle, but is loose on the same, being provided with a spring-pawl cooperating with a ratchet-wheel on the axle, so that the toothed wheel may move freely in one direction without taking the axle with it, while in the other direction it moves together with the axle.

In order to ascertain from the outside which receptacles A are still filled with carbid and which are empty, a little indicator K is arranged on each carbid-receptacle A, which indicator is turnedl by an arm I, connected with the disk G at the point where the carbid-receptacles discharge. In order to permit the downward movement of the bell without a corresponding backward movement of disk G, gear-wheel O is looselyT mounted on shaft O/ and carries a pawl o, pressed by a spring 0' into engagement with a ratchet-Wheel 02 on the shaft O. A gravity-pawl g, engaging circularly-arranged ratchet-teeth g on the under side of the disk G, prevents any backward movement thereof. If this indicator K stands vertical, the reservoir is filled if hori` zontal the reservoir is empty. In manipu lating the apparatus it is only necessary td feed the emptied carbid-reservoirs at determined intervals again with carbid.

The advantages which distinguish the acetylenegas generator described above over others with automatic action consist,primarily,in the stationary arrangement of the individual carbid-chambers, so that they need not move in the operation of the apparatus. Furthermore, another advantage is obtained for the presentapparatus because the various parts effecting the automatic feed of carbid are arranged outside of the gas-room. These mechanisms are, therefore, not exposed to the humidity and the highly destructive influence of the sulfureted hydrogen, the phosphureted hydrogen, and the ammonias, rbc., developing in the generation of the acetylene. The particular construction of` the regulating mechanism renders the whole apparatus rather insensible against shocks and similar inuences. Furthermore, carbid cannot under any circumstances be introduced into the water at an improper time. This feed of carL bid is regulated by the operation of the apparatus in the most positive manner. over, this apparatus permits no air to penetrate into the generator when the carbid-rea ceptacles are being filled.

I claim- In an acetylene-gas generator in combina= tion, a generator-chamber, a fixed top or cover for the same, a circular row of xed tubes passing through the said fixed top and dipping into the Water of the generator-chamber, carbid-receptacles of less diameter than the said fixed tubes mounted'on top ofsuch tubes and provided with air-tight covers at the top, throttle-valves mounted within said tubes and forming movable bottoms for the said receptacles, operating-shafts for holding the said bottoms up against the shoulders formed between the tubes and the receptacles, said operating-shafts having their operative ends placed outside the generator-chamber and means for operating the shafts substantially as described.

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