DIP-PIPE.

SPECIFIGATION forming part of LettersV I'atent No. 247,386, dated September 20, 1881. Application filed July G, 1881. (No model.)

.To all rwhom 'it may concern:

Be it known that I, GEORGE A. MOILHENNY,

of Washington, in the District of Columbia,

draulic main, and encircling the upper end ofl the ascension-pipe, which, under my construction, rises through the bottom of the main, said dip-pipe being provided with a removable lid or cover, and with a valve, whereby communication may be established or cut ofl' between its interior and the open space of the hydraulic main.

The accompanying drawing represents a vertical central section of my apparatns.

'Ihe object of my invention is to cheapen the construction of the apparatus, to facilitatc the cleaning or-clearing ot' the pipes, and to provide means for instantly sealing or unsealing any dip-pipe of the series and its corresponding retort.

To this end I construct the parts as shown in the drawing, in which A represents the hydraulic main, B the ascension-pipe passing up through the bottom of the main and rising to a proper height above the liquid therein, and O the dip-pipe passing down through the top of the main, encircling the upper end of the ascension-pipe, and dippinginto the liquid to a sutticient distance to eftectually seal the pipe. Under this arrangement the gas arising in the ascension-pipe will pass out at the top of the same and descend through the annular space ct between said pipe and the encircling dip-pipe to the liquid, through which, unless other escape be afl'orded, it will force-its way beneath the lower end of the dip-pipe and up into the open space of the main, whence it will pass through the intermediate parts ot' the apparatus to the gas-holder.

. For the purpose of permitting the ascension and dip pipes to be readily cleaned or cleared of obstructions the latter is furnished with a removable lid,D, which maybe secured in place in any suitable manner, but which is preferably formed with a beveled edge to fit a mouth of correspondin g form, and held to said mouth or seat by a screw, E, hearing upon it at the center,in the same manner as the lids of gasretorts are secured in place.

In order that the dip-pipes may be readily sealed or unsealed,I provide each With avalve, F, in its side at a point above the liquid in the main, and furnish said valvewith an operating-stem, G, Which passes through a stutfingbox, H, and is preterably'connected with an actuating-lever, I.

It will be seen that by simply opening or closing the Valve free communication may be established or cut off between the ascensionpipe and the hydraulic main quickly and With case. and Without moving or adjusting the dippipe. It will also be seen that When the Valve is closed the gas may escape beneath the end of the dip-pipe, as usual, though prevented from returning to the ascension-pipe by reason of the rise of the sea-ling liquid in the annular space a, when the pressure from within the ascension-pipe ceases.

Under the above construction each retortot' the entire series may be sealed or unsealed without affecting others of the series, and each ascension pipe may be readily reached for cleaning without removing the dip-pipe or disturbin g the Valve and its fixtures.

I am aware that the ascension pipe has hitherto been arranged to pass up through the bottom of the hydraulic main; that the dippipe used therewith has been provided with a removable lid, and that a valve has been applied to`a dip-pipe for the purpose of sealing and unsealing the same; hence [do not claim these features per se but What I do claim isl. `In combination With an ascension -pipe passing upward through the bottom of the hydraulic main, a dip-pipe descending through the top of the main and encircling the ascension-pipe, and provided with a valve whereby communication may be opened or closed between the ascension pipe and the main, substantially as set i'orth.

2. In combination with an ascension-pipe passing upward through the bottom of the hydraulic main, a dip-pipe descending through the top of the main and encircling the ascension-pipe, provided'with a removable lid, and

with a Valve, whereby communication maybe' established between the ascension -pipe and the main.
