Abstract

12,934. Bates, C. June 17. No Patent granted (Sealing fee not paid). Gas and like engines, purifying exhaust of. The exhaust gases are filtered and deodorized by passing them first through a liquid, then through cooling- tubes, and then again through liquid. In the apparatus illustrated in Fig. 1, the gases are forced by a pump or fan along the pipe d into the chamber a and then pass through the oil or other suitable liquid in the chamber to the tortuous pipes e, f, g, h communicating with expansion chambers i, i<1>. Baffles c, which slide between guides d in the chamber, compel the gases to circulate in the manner described but allow the liquid to pass through suitable perforations therein. The last pipe h of the series dips below the level of the liquid, and the gases escape to a suitable reservoir through a pipe l. The tortuous pipes preferably are fitted to the liquid reservoir and the expansion chambers by coned surfaces forming joints, while the cover-plates preferably are fitted on to the reservoir and expansion chambers by similar wedgeshaped surfaces. Openings closed by screw-caps b<1>, j, k are made to facilitate cleaning and repair of the apparatus. The apparatus is stated to be applicable particularly for use in connexion with the apparatus described in Specification No. 9752, A.D. 1908. The fan or pump may be dispensed with. The Provisional Specification states that the purified gas may be used for motive power or illuminating purposes.
