This The valves and the lever 51 are inclosed within 9 5 application in so far as Fig. 1 is concerned a casing, which is preferably roof -shapcd, and the description thereof being in part a above the lever 51, as shown in the figures, division of my copending application, Serial and which extend down around the valves in a way to prevent the entire mass of carbid pressing down upon the valves and interfering with their operation. There is provided a safety valve or stop 70, mounted to swing under and cut off the'feeding of carbid from the hopper when free to move, but normally held in cooperative position, as shown in Fig. 1, by a detent 31, connected as shown, to be supported by a iioat 73. If for any reason the water-level within the generator is forced either by an excess of gas-pressure or the drawing off of the water, vthe fall of the float 73 draws down the detent 71 and releases the safety valve or stop 70, causing it to swing beneath the valve-opening and prevent any feeding of carbid. The gas passes from the generating-chamber to the gasometer through gas-pipe 83. In order to reduce the fiuctuations of pressure which occur by the sudden feeding of carbid within the generator, an annular space 80 of large area is provided above the generating-cham ber, into which the water may be freely forced by an excess of pressure, as indicated by the arrow 81. The space 80 therefore forms a partial reservoir into which a considerable volume of water may be forced by an excess of pressure within the generator. The water iiows back in to the generatingchamber as the excess of pressure is relieved by the escape of gas into the gasometer. In order to insure the venting of the machine both when introducing and withdrawing water, suitable means are provided in accordance with theinvention. This means, presently to be described, prevents the formation of a partial vacuum in the generator when drawing off water and also prevents air being forced into the gasometer when the generator is being filled with water. In Fig. l a special automatic trap is employed for carrying out the invention. As shown, a water-holding vessel 75 is supported somewhat above the normal water-level in the generator and substantially at the top of the generating-chamber, and into this dips and is sealed a vent-pipe 76, which communicates above with the atmosphere. Surrounding the lower end of the vent-pipe 76 is a depending sleeve 77,* which is also'Water-sealed in the receptacle 75, and it is closed gas-tight at its upper end. Assuming that the sleeve 77 extends, say, three inches down into the water within the vessel 75, air will be admitted freely to the interior of the generatorl as long as the pressure within it is reduced to three inches less than atmospheric pressure. As, however, the horizontal section of water admitted within the sleeve 77 is large as compared to the annular space intervening between the sleeve and the walls of the vessel 75, the admission of air in carryingdown the water-level within the sleeve 77 depletes the amount -of water within the y receptacle 75, so that the air may escape still the generator. As soon, however, as the water in the generator rises high enough to pour into and fill the vessel 75 it of course reestablishes the seal, because then the water will reach the foot of the air-pipe 76 and completely seal it against the escape of air or gas. Therefore it will be seen that this special trap admits air readily to the generator and also permits the escape of air while the generator is being filled with water; but as soon as the generator is filled it reestablishes the complete sealing of gas within the generator.

In Figs. 2, 3, 4, and 5 a diierent mode of carrying out the' invention is illustrated as a modification which has been found to operate efliciently and well. While the generator may be constructed in any suitable manner, I

4have preferably shown the same form of construction illustrated in my copending application, Serial No. 142,613, filed February 9, 1903. In this form of generator there is a partition E inside of the outer casing D, the walls of which are extended upwardly at F to form what may be termed a filling-bib, communicating with the inside of the generator by means of a downwardly-extending sleeve Gr, which forms a water seal for the stirrer rod H, suitably connected to the stirrer I. The filling-bib is partly covered over bythe top J, while a suitable hinged lid or cover K affords provision for charging the machine with water. As shown in the drawings, the neck L of the machine is supported from the partition E and extends upwardly through the top J, supporting the hopper O, within which is arranged the carbid-valve. Any suitable mechanism may be provided for operating the valve, none, however, being shown in this instance, as it forms no part of the present invention. An overflow-opening y' is provided in a suitable position on the generator and suitable pipe connections are provided leading from the generator, while a vent-pipe communicates with the outside atmosphere. The vent-pipe Z also communicates with the inside of the generator, as shown in this instance through the interposition of the piping while a vent-cock q is arranged in the vent-pipe to control the same. The lid or cover K, as shown, is provided with a hinged pivot-rod fr at one side,

(best shown in Fig. 4,) while at the other side said cover is connected to the vent cock or valve g, whereby in opening and closing the cover K the valve q will be operated. Any suitable means maybe provided for operatively connecting' the lid or cover K to the valve q, as shown, the lid K being provided with a socket .5', intowhich lits a squared projection t on the valve. The arrangement of the lilling cover or lid K, operatively connected with the vent Q, insures the ventingof the-machine when introducingwater into the v same, because when the lid is opened the ventroo IIO

cock is opened. In order to insure the venting of the machine when water is being withdrawn, in this instance, as shown in the drawings, interlocking connections are provided, including' the cover K and operatively connecting the vent and the Hush-out. The flushl out or lime-gate u, as shown, is provided with an upwardly-extending rod o, the upper end of which extends within the socket w for the hinged pivot 'l' of the lid K. The pivot r is provided with a iiattened or recessed portion fr, which moves into such position when the lid K is opened that the rod c may move upwardly past said flattened portion of the pivot fr; but when the lid K is closed the rod @cannot be moved upward. According to this construction the lime-gate u cannot be opened unless the lid K is opened, and it will also be seen that the lid K is locked open as long as the lime-gate u remains open, because when the interference-rod c is moved upward past the flattened portion of the pivot '7 the lid cannot be closed again until the rod c is lowered. The object of locking the water-charging rod or cover K open in the construction described when the lime-gate is open is to prevent the drawing off of the residuum of water with the closed vent, for it will loe seen that by locking the lid K open the vent q is also locked open. Other suitable interlocking connections may be provided, if desired, between the lime-gate and the vent q without departing from the spirit of the invention.

It will thus be seen that widely-diiering forms of apparatus may be provided for carrying out the leading objects of this inventione-namely, to insure the venting of the machine both when charging Water in and flushing out. In Fig. 1 a special automatic trap is shown, while in the remaining iigures positive mechanical interlocking connections are provided between a vent-cock and a flushout. Theinvention,broadlyconsidered, therefore contemplates any suitable operative means for carrying out the objects of the invention, as hereinbefore stated.

The mechanical interlocking devices herein shown and described in connection with Figs. 2. 3, el, and 5 form the specific subject-matter of some of the claims of my copending application, Serial No. 14Q,613,'filed February 9, 1903, the generic claims in this present application being applicable to both forms of apparatus shown herein, with specific claims for the subject-matter of Fig. l.
