IMPROVEMENT IN APPARATUS FOR THE MANUFACTURE QF GAS.

Specification forming part of Letters Patent No. 122,025, dated December 19, 1871.

To all whom it may concern:

Be it known that I, EDWARD J oNEs, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain nevir and useful Improvements on Stand-Pipes and Mouth- Pieces for Gas Apparatus, of which the following is a specification:

The nature of my invention relates to ilnprovements on stand-pipes and mouth-pieces for gas apparatus, consisting in the employment of a box or receptacle containing water, surrounding the stand-pipes or mouth-piece leading from the retorts at any suitable place. Said box may be cast on, attached or connected to the stand-pipe or mouth-piece, as may be convenient, and is to be provided with one or more openings, through which the water can evaporate up in the standpipe or mouth-piece, and thus dissolve and prevent the accumulations of coal-tar for the purpose of effecting aclear and unobstructed passage for the gas through the standpipe and mouthpiece, as will now be fully shown and described.

On the drawing, Figure l represents a front elevation of my invention. Fig. 2 represents a central longitudinal section over the line A B taken on Fig. l; and Fig. 3 represents a crosssection over the line C D, also taken on Fig. l.

Similar letters refer to similar parts wherever they occur on the drawing.

The object of this my invention is to remove the accumulation of coal-tar in the stand-pipes and mouth-pieces of gas apparatus, for which purpose I surround the stand-pipes or mouth-pieces on 011e or more sides with a receptacle containing water, and provide the said receptacle with one or more openings, leading in the stand-pipe or mouth-piece, through which the water can evaporate and rise with the gas up through the mouthpiece and stand-pipe, and thus dissolve, soften, and combine with the coal-tar, making it so thin that it will iiow easily back to the retort-s and thus keep the stand-pipes and mouth-pieces clear from obstructions and allowing the gas from the retorts to be conducted freely to the hydraulic main.

On the drawing, a is the gas-retort mouthpiece, and b is the lid. c is the stand-pipe, the lower end of which rests in a socket attached to the upper side of the mouth-piece a, as shown. At a convenient place on the stand-pipe o l cast on, attach, or connect a receptacle, d, that may surround the stand-pipe wholly or in part, as may be desired. The upper end of the receptable d is provided with one or more openings, e e e, on the circumference of the stand-pipe c, through which openings the steam from the receptacle d will be evaporated and rise upward through the stand-pipe, thus dissolving the coal-tar accumulations in the stand-pipe. The receptacle d is provided with a pipe, f, stop-cock g, and funnel It, by which arrangement I can iill the receptacle d from the outside. The receptacle d may either be attached to the regular stand-pipe, as shown in Fig. 1, or it may be attached to a short piece, c, provided inits upper end with a suitable socket or similar arrangement, whereby it may be connected to the ordinary stand-pipe, as shown in Fig. 2. The advantage of thelatter arrangement is that old gas-works can easily be provided with my improvement simply by cutting off the or dinary stand-pipes a little and to connect them with the short pipe, c, and the receptacle d attached thereto, as shown.

The operation of my invention is as follows: When the lid b is removed during the charging oi' the retort, I open the cock g and fill the receptacle d with water by pouring it through the funnel h, and when full I close the cock g andreplace the lid b as usual, when the heat from the retort will gradually evaporate the water contained in the receptacle d, that rises up through the stand-pipe, and thus eitect the desired object, viz., softening and preventing the coal-tar from accumulating and clogging up the stand-pipe and mouth-piece. Instead of placing the receptacle d on the stand-pipe Imay also put it around the mouth-piece a, as shown in dotted lines 'i onthe figures. In this case I can either let my receptacle run all around the mouth-piece, or let it eX- tend only on a part of said mouth-piece, as may be desired.

Having thus described fully the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- A receptacle, d, cast onto, attached, or connected to a stand-pipe or mouth-piece for gas apparatus, provided with one or'more openings, c e e, said receptacle el surrounding the stand-pipe or mouth-piece wholly or inpart, for the purpose as herein fully set forth and described.

EDWARD JONES.
